The total number of hours for these services combined over two months was M = 34 . Estimated total costs of health-related services were M = 1210 EUR (SD = 2160 EUR); indirect societal costs were M = 1624 EUR (SD = 1317 EUR). Regression analyses suggested that costs rise with age and presence of intellectual disabilities, but not with severity of autism; (4) Conclusions: The high extent of community-based services indicates good accessibility but also considerable variation in the receipt of services. The costs of autism services are considerable. Further research is needed to investigate whether services received match individual needs. Autism spectrum disorder (ASD) refers to a range of lifelong neurodevelopmental conditions characterized by the presence of early appearing symptoms in two core domains: impairments in reciprocal social communication and the presence of restricted interests and repetitive behaviours DSM-5; ICD-11) . ASD aff; ICD-11 https://www.who.int/news-room/fact-sheets/detail/autism-spectrum-disorders, accessed on 1 April 2020) recommend evidence-based psychosocial interventions including behavioural treatment and parent skills training programmes which can minimalize limitation in communication skills and social behavioral skills with improving well-being and quality of life for both individuals with ASD and their parents. Based on current best evidence, guidelines developed by Autism-Europe [It is important to provide individuals with ASD and their families with support to live their best possible life. There is no cure for autism nor one care package that suits everyone. People with autism require different support at each age of their lives, and it is therefore essential to ensure the right type of evidence-based therapy at the right time. Relevant guidelines often emphasize general principles in the absence of more specific evidence.

For the current study purpose, only data collected at baseline on scores of the ADOS and ADI-R, IQ level, as well as costs and concomitant treatments were included. Parents answered a detailed questionnaire regarding services received and out-of-pocket expenses during the past two months. The following data were collected:Respondents were asked to reply with regard to the last 2 months. The limited recall time frame was used to minimalize the recall bias following other economic evaluations e.g., ,36.

All health services costs were sourced from personal communication and represent typical costs in Austria, a Central European country and one of the countries where data were collected. Heath services costs were set up to be 84 EUR per 60 min (one session) based on 1:1 setting, and discounted for group settings, assuming a group size of 5. Costs of institutional stay (310.08 EUR per day) and outpatient treatment (167.10 EUR per contact/visit) were retrieved from a report of Unit Costs of Health and Social Care [https://ec.europa.eu/eurostat/en/web/products-datasets/-/ILC_DI08, accessed on 4 March 2021), the following unit costs were obtained: 1946.08 EUR per month for full-time work where both parents had a university degree; 1391.42 EUR per month where both parents had 12 or more years of education; and 1129.42 EUR per month where at least one parent had less than 12 years of education or education level was unknown. No unit costs were imputed for medication and special diets because these costs were found to be negligible in children with ASD [https://ec.europa.eu/eurostat/tgm/table.do?tab=table&init=1&language=en&pcode=tec00118&plugin=1, accessed on 4 March 2021).Unit costs were inserted where a service was used but parents reported no expense for the service. Costs were transformed into EU-28 average using purchasing power parity , and intellectual disability (below-average intelligence) and health services costs and societal costs. Following literature that the age and severity of autism symptoms are significant predictors of costs for children at preschool age and in an = 140).A sensitivity analysis was used to determine how data retrieved from non-European countries affected the obtained health services costs and societal costs. In order to determine the robustness of our results by examining the extent to which results of health services costs and societal costs are affected by country of origin, we calculated costs including only 217 children from Europe and excluding individuals from other non-European countries and clinical judgement (n = 140), the results of which indicate that 47% of children (n = 163) had IQ below 70. The majority of individuals attended to school (62%), while 22% to full-time care and 11% to part-time care. More details can be found in the top half of The total of 357 children (83% boys) were included with a mean of age 5.4 years (SD = 0.9). As can be seen from In regard to parents\u2019 situation of work, the majority of mothers were homemakers (34%) followed by 26% being part-time employed, while the majority of fathers were working full-time (74%). Regarding education, many parents had a university degree , followed by education equivalent to high school , and less than high school . The bottom half of Of 357 children, 122 (34%) received specialist autism services; 149 (42%) received sensory/motor therapy; 205 (57%) received speech/language therapy; 35 (10%) received play therapy; 55 (15%) received behavioural interventions; 31 (9%) received social skills training; 47 (13%) participated in therapeutic recreational activities; and 59 (17%) received other services . The totThe sum of indirect societal costs was M = 1624 EUR over the last 2 months with a wide range . It can be seen that the SDs are relatively high compared to the means; sometimes higher than the means. This reflects the skewed nature of these data, which is a common phenomenon in health economic data ,41.p < 0.048) and intellectual disability (p < 0.005) on health costs attended school, 91 of included children (25%) attended kindergarten ; while 5 (1%) attended none of aforementioned. Regarding other services, 10 children (3%) had an institutional stay over the last 2 months; 24 (7%) received outpatient treatment; 55 (15%) received medication; and 38 (11%) a special diet. It can be seen from the data in n = 85; 24%); 111 had reduction in working hours (31%) due to a child care assist and required an additional aide at school or home .The results about schooling indicate that the majority of individuals from European counties . It may be explained by the fact that communication problems belong to the core autism symptoms; thus, children may benefit the most from this kind of treatment at this early stage of life. The second and most frequently chosen form of therapy was sensory and motor therapy . High use (42%) of this intervention might be due to the core nature of sensory symptoms in individuals with ASD, particularly to sensory over-responsivity . On the Estimated total costs of health-related services were M = 1210 EUR for a 2-month period, while specialist autism services contributed to these costs the most (315 EUR) followed by behavioural intervention (284 EUR) and speech/language therapy (251 EUR).Roggie and Janssen in theirThe present results indicated a high diversity among children\u2019s needs and therefore health care services used. Institutional admissions occurred in 12 cases (3% of cohort), while visits to psychiatric, somatic, or other specialized outpatient services occurred in 37 cases (10%). Even though our data indicated a relatively low mean cost of institutional stay (3 EUR) and outpatient services (1 EUR) over a period of two months when averaging across the whole sample, the wide range of costs show that there were families who incurred very high costs related to these services, whereas other families did not have these costs at all. A large and growing body of literature has investigated healthcare utilization expenditures for individuals with autism. Other research in medical and healthcare costs has emphasized the higher costs for individuals with autism compared to individuals without ,19,21,22One third (31%) of the included families in our sample experienced some costs related to medication. Even though the present data indicate a relatively low cost of medication (approx. 6 EUR) over a period of two months, the range of costs (from 0 to 290 EUR) emphasizes that there were families who incurred very high costs related to these services, and families who did not have these costs at all. There is a large volume of published studies e.g., describiSeventeen percent of the included children in our study experienced costs associated with a special diet; across all included children, the cost of special diet was on average 7 EUR over a period of two months. The broad range of these costs from 0 to 455 EUR indicates that some families have had a very high cost associated with a special diet. These results are likely to be related to a possible relationship between nutritional status and general condition of ASD children. Peretti and colleagues emphasizResults of the present study indicated the indirect societal costs to be around 1624 EUR over a period of two months. In terms of societal costs, an additional aide at school or home contributed the highest costs (621 EUR), followed by reduction in working hours (M = 524 EUR), childcare/school (M = 461 EUR), and child care help (M = 18 EUR).Our findings seem to be consistent with other research which found a high economic burden linked with ASD on society . For insFamilies of individuals with ASD face significant economic burden due to reduction or interruption of employment . The resData from our study indicate that the reduction in working hours was linked with costs of 524 EUR; child care help with additional costs of 18 EUR over a period of two months. Our findings have confirmed previous results ,30 that It was hypothesized that younger participants with a diagnosis of autism with intellectual disability will bear higher costs compared to those with older age, with broader ASD category and with intellectual disability. Regression calculation of costs confirmed that health costs change with age for children with ASD during ages 4\u20137 and with presence of intellectual disabilities, but not with societal costs. Our results indicated that health costs increased by 213 EUR per additional year of child\u2019s age and by 566 EUR for children with intellectual disability, indicating that both age and intellectual disability are significant factors related to total health costs. However, such a relationship was not observed for the social costs.Our results are in line with earlier findings. Research by J\u00e4rbrink found thThe results of our study did not confirm the predictive role of symptoms severity in the health costs and societal costs measured by ADOS total score, which is consistent with another study . HoweverLittle is known about autism-related costs in Europe. Total costs including health services costs and societal costs were estimated to be around 2834 EUR for the whole sample size compared to 2489 EUR for individuals from Europe. The results obtained from the sensitivity analysis showed that for children from European countries the pattern of services used is similar (but not exactly the same) for those from non-European countries. Children outside Europe attended more often health care services in the pre-school period, which has a direct impact of health services costs (1210 EUR vs. 740 EUR for the 2 months). Speech/language therapy; behavioural intervention; and sensory/motor therapy were associated with the highest costs for children from Austria, Israel, Italy, Norway, UK; while for the whole sample the main cost drivers were specialist autism services followed by behavioural intervention and speech/language therapy. Estimated societal costs were relatively close both in Europe and outside with the same key cost driver .The generalisability of these results is subject to certain limitations. For instance, the most important limitation lies in the fact that the study used self-reported data of costs threatened by self-reporting bias as: social desirability and recall bias , but theThe present research explores, for the first time, the costs of services received and associated costs for children with ASD bason on 5 European countries and 4 non-European countries . Total costs including health services costs and societal costs, were estimated to be around 2834 EUR over last 2 months with a wide range from 84 EUR to 26,051 EUR. Estimated total costs of health-related services were around 1210 EUR and indirect societal costs were 1624 EUR (with a wide range from 0 to 6263 EUR). Specialist autism services; behavioural intervention; and speech/language therapy were key cost driver in this group followed by sensory/motor therapy (213 EUR) play therapy (32 EUR), therapeutic recreational activities (23 EUR) and social skills training (12 EUR). Among indirect societal costs the important cost driver was an additional aide at school or home (621 EUR) followed by reduction in working hours (524 EUR), childcare/school (461 EUR) and child care help (18 EUR).The current findings add to a growing body of literature on services and costs for children with ASD by confirming that families of children with ASD bear higher costs related to the child\u2019s age and child\u2019s intellectual functioning . This study has also shown that the diversity of approaches recommended in guidelines across countries. The pattern of services used by children with ASD from European countries is similar (but not exactly the same) for those from non-European countries. The high extent of community-based services indicate good accessibility but also considerable variation in the receipt of these services. Notwithstanding the limitations, these results suggest that the costs of autism services are considerable. There is still abundant room for further progress in evaluating data on services received by individuals with ASD and associated costs for Europe. To develop a full picture of costs additional studies targeting adolescents and adults with ASD is recommended. Further research is needed also to investigate whether services received match individual needs."} +{"text": "The Centers for Medicare & Medicaid Services defines a hospital readmission as an inpatient stay that begins within 30 days of the discharge date of an index admission, to the same or a different hospital. The aims of the study were to analyze the recurrent readmissions of older persons admitted to a community hospital with diagnoses of: Chronic Obstructive Pulmonary Disease (COPD), Pneumonia (PNA), and Congestive Heart Failure (CHF). Based on the results, we will develop additional strategies that can be used to reduce the rate for hospital readmission for older patients. A retrospective chart review of hospitalizations was conducted. Among 30 readmissions, the mean age was 79.5\u00b114. The index disposition was distributed among three destinations: self-care (27%), home health organization (40%), and to skilled nursing home (33%). Most of the readmissions were for CHF (27%), COPD (10%), and PNA (13%), the only other large category include respiratory failure (10%). The readmission disposition was different from the index disposition: self-care (7%), home health organization (47%), and to skilled nursing home (20%). After hospital readmission within 30 days, older persons were more likely to be discharged to home health care organization than self-care, p<0.05. Actions that can be taken by hospitals to reduce 30-day readmissions to maintain older person independence include: clinical readiness of patients for discharge, proper infection prevention techniques, reconciling medications, good communication, and adequate patient education. This study reports that that older persons are at higher risk for unplanned hospital re-admissions and often lose their independence."} +{"text": "While Alzheimer\u2019s disease (AD) and vascular dementia (VaD) may be accelerated by hypercholesterolemia, the mechanisms underlying this association is unclear. Using a novel, 3-step study design we examined the role of cholesterol catabolism in dementia by testing whether 1) the synthesis of the primary cholesterol breakdown products (bile acids (BA)) were associated with neuroimaging markers of dementia; 2) pharmacological modulation of BAs alters dementia risk; and 3) brain BA concentrations and gene expression were associated with AD. We found that higher serum concentrations of BAs are associated with lower brain amyloid deposition, slower WML accumulation, and slower brain atrophy in males. Opposite effects were observed in females. Modulation of BA levels alters risk of incident VaD in males. Altered brain BA signaling at the metabolite and gene expression levels occurs in AD. Dysregulation of peripheral cholesterol catabolism and BA synthesis may impact dementia pathogenesis through signaling pathways in the brain."} +{"text": "The expression of the chosen genes was confirmed by RT-qPCR technique. Thus, it can be assumed that the identified genes involved in the regulation of growth and development of muscle tissue and the processes of protein metabolism in the examined cattle breeds may be responsible for the greater gain of muscle mass in beef-breed bulls.The aim of the study was to compare the transcriptomic profiles of fully differentiated skeletal muscle derived from bulls belonging to different breeds of varying performance. Microarray analyses were performed to determine the differences in the expression profiles of genes between semitendinosus muscles of 15-month-old beef-breed bulls (Limousin\u2014LIM and Hereford\u2014HER) and dairy-breed bulls (Holstein Friesian\u2014HF). These analyses allowed for the identification of those genes the expression of which is similar and characteristic of fully differentiated muscle in beef breeds, but differs in skeletal muscle of a typical dairy breed. The analysis revealed 463 transcripts showing similar expression in the semitendinosus muscle of beef breeds (LIM/HER), in comparison with the dairy breed (HF). Among the identified genes, 227 were upregulated and 236 were downregulated in beef breeds. The ontological analyses revealed that the largest group of genes similarly expressed in LIM and HER was involved in the processes of protein metabolism and development of muscle organ. In beef breeds, some genes involved in protein synthesis and proteolysis showed an upregulation, including The online version of this article (10.1007/s13353-020-00577-1) contains supplementary material, which is available to authorized users. The quality of livestock meat is very important from an economic point of view, and hence, research has been carried out over the past few decades to increase the production of beef, accelerate the growth rate of cattle, and improve the quality of meat cattle breed and the early-maturing Hereford (HER) breed (with a large proportion of well-marbled muscle) are both beef breeds, whereas the early-maturing and poorly muscled Holstein Friesian (HF) is a typical dairy breed. The gains of muscle mass up to the 16th month of life are about 1000\u20131300, 850\u20131400, and 800\u20131000\u00a0g per day in LIM, HER, and HF breeds, respectively. The reason for these differences observed in the gain of muscle mass is not sufficiently explained, and the genes determining the rate of growth and metabolism of muscle tissue in these breeds remain to be identified skeletal muscle in cattle depending on their breed and performance. The analysis allowed for a better understanding of the genetic regulation of the development of muscle tissue, as well as determining the putative genes involved in myogenesis and development of muscle tissue in beef-breed bulls.It was assumed that the results obtained will enable the selection of those genes that are involved in the process of myogenesis and maturation of skeletal muscle and modification of their expression for achieving greater gains of muscle mass in beef-breed bulls.All the procedures related to animal experiments were approved by the Local Ethics Committee.n\u2009=\u20094), HER , and HF used as a reference. The bulls were housed, fed, and slaughtered at the age of 15\u00a0months as described earlier and total RNA isolation and validation were done as described in previous papers of 15-month-old bulls from beef breeds Limousin (LIM) and Hereford with bulls of the Holstein-Friesian (HF), a dairy breed (reference), was done using the GeneSpring software , t test with p\u2009\u2264\u20090.05 and fold change \u2265\u20091.3 as the criteria of significance. Each comparison was performed individually, in four biological repetitions. In the subsequent stage, a comparative analysis of both transcriptomes was performed, aiming at identifying common genes with different expression in the muscles of bulls from beef breeds . The data obtained from the microarray experiment were deposited in the NCBI Gene Expression Omnibus database and numbered GSE137565 (HER vs. HF) and GSE137566 (LIM vs. HF).The gene expression profile was analyzed using Bovine (V2) Gene Expression Microarray 4\u2009\u00d7\u200944\u00a0K oligonucleotide slides and Two-Color Microarray-Based Gene Expression Analysis kit . Probe labeling, hybridization, signal detection, and data extraction were done as described in a previous paper was used as a nonregulated, reference gene for normalizing the expression of the verified genes was applied. The mRNA sequences of the genes selected for validation were obtained from the NCBI Nucleotide database. Primer sequences were designed using the Primer3 and Primer-Blast software (NCBI database) and then checked using Oligo Calculator as described previously . For the purpose of publication, the color immunoblot images were converted into black and white in the Odyssey software.The protein extracts obtained from the skeletal muscle tissues were lysed with RIPA buffer supplemented with protease inhibitor cocktail and phosphatase inhibitor cocktail for 30\u00a0min at 4\u00a0\u00b0C. The lysates were cleared for 30\u00a0min at 14000\u00a0rpm, and the supernatants were collected. The concentration of protein in the lysates was determined using Bio-Rad Protein Assay Dye Reagent according to the manufacturer\u2019s instructions . The proteins (50\u00a0\u03bcg) were resolved by SDS-PAGE and transferred onto a PVDF membrane . For immunostaining, the membranes were blocked with 5% nonfat dry milk in TBS containing 0.5% Tween 20. The membranes were then incubated with the following primary antibodies: monoclonal anti-mouse GDF-8 antibody (1:100) and polyclonal goat GAPDH antibody (1:500). Then, the membranes were washed three times for 15\u00a0min and incubated further with appropriate secondary antibodies conjugated with an IRDye 680 or IRDye 800 CW fluorophore (1:5000). An Odyssey Infrared Imaging System was used to analyze the fluorescence. The scan resolution of the instrument was set at 169\u00a0\u03bcm, and the intensity at 4.

In addition, during the development of data from microarrays, numerous internet databases, grouped in NCBI, such as GenBank, OMIM, PubMed, and iHOP, were used.The results were subjected to ontological analysis using the following online available databases: Panther Classification System was performed in terms of biological processes, in which products of expression of these genes might be involved. Ontological analysis demonstrated their relationship with 13 biological processes, including the following: metabolic processes 236 genes), cellular processes (161), regulation of biological processes (101), developmental processes (63), localization (54), response to stimulus (53), cellular component organization or biogenesis (39), immune system processes (35), multicellular organismal processes (26), cell adhesion (17), apoptosis (11), reproduction (5), and locomotion (1) , followed by phosphate-containing compound metabolic process (31), nitrogen compound metabolic process (27), biosynthetic process (17), catabolic process (11), generation of precursor metabolites and energy (5), coenzyme metabolic process (3), sulfur compound metabolic process (2), and vitamin metabolic process (1).Further functional classification of DEGs demonstrated that among 195 genes involved in primary metabolic processes, the highest share was exhibited by the genes involved in protein metabolic process (99), nucleobase-containing compound metabolic process (91), lipid metabolic process 20) carbohydrate metabolic process (17), and cellular amino acid metabolic process (5) Fig. . The mul0 carbohyUsing the Pathway Studio software, a network of relationships was performed for the differentially expressed genes assigned to the processes associated with protein metabolic process. This enabled a visualization of interaction between DEGs and additionally demonstrated the affiliation of genes to two major processes associated with protein metabolic process: protein synthesis 36 genes) and proteolysis (33 genes) , mesoderm development (19), anatomical structure morphogenesis (19), ectoderm development (12), apoptosis (11), cell differentiation 5), embryonic development (3), pattern specification process (2), and endoderm development (1) .

These results confirm the results obtained with microarray analysis and exhibited the same direction of expression change as in the microarray experiment.In order to verify the results of transcriptomic analysis, validation of gene expression with the use of qPCR technique has been performed. For the purposes of result verification, seven genes were selected, demonstrating similar changes of expression in both beef breeds (LIM and HER) compared with typical dairy breed (HF), associated with the processes of muscle tissue development and protein metabolism processes. Results of verification with real-time qPCR are presented in the form of block diagrams. The level of mRNA expression is presented as \u0394\u0394Ct Fig. .

Increased level of follistation expression and decreased myostatin expression level in skeletal muscles of beef breed bulls indicate the role of follistatin as antagonist of myostatin in the regulation of myogenesis, and it may play a significant role in stimulating development and growth of muscles in these breeds, and as a consequence greater gains of muscle mass. Moreover, the faster growth and development of muscle tissue in beef bulls can be associated with the elevated expression of fhl2 and fhl3 genes encoding FHL proteins , playing putative role in the process of skeletal muscle differentiation including formation of myotubes and expression of proteins characteristic of muscle fibers. The genes identified in this study, involved in the regulation processes of growth and development of muscle tissue and protein metabolism processes in the tested cattle breeds, may be responsible for greater muscle mass gains in bulls from beef breeds and may constitute a new cattle selection tool towards highly efficient meat production, which may be of considerable economic importance.Comparison of transcriptomic profiles of fully differentiated skeletal muscle originating from 15-month-old bulls from various breeds with different performance enabled formulation of the following conclusions. Greater growths of muscle mass in bulls from beef breeds than in the dairy breed (HF) stem from the differences in protein transformations and are associated with elevated expression of genes stimulating synthesis and inhibiting degradation of proteins (ESM 1(DOCX 73\u00a0kb)"} +{"text": "Given extended life expectancy, family caregivers are needed to provide care for older adults at home.

Activation mapping of the clinical VT (VT1) revealed the earliest ventricular activation site at the right ventricular outflow tract (RVOT).

Activation mapping of VT2 established the site of origin at the commissure between the right (RCC) and left (LCC) coronary cusps. This case is indicative of the presence of myocardial fibers displaying preferential conduction properties from the RCC\u2013LCC commissure to a breakout site at the RVOT. The QRS morphology was suggestive of a right ventricular outflow tract (RVOT) site of origin (SOO). An electrophysiologic study was performed in a fasting state without sedation.

Following the change in QRS morphology, an additional attempt of RF delivery was performed at this site but failed to suppress the arrhythmia. Meticulous activation mapping of the VT2 was subsequently performed at the RVOT, the left ventricular outflow tract (LVOT) including the coronary cusps, and the coronary venous system [great cardiac vein (GCV)]. The new activation mapping attempt revealed the earliest activation site at the RCC\u2013LCC commissure (\u221225 ms) and 2C. Catheter ablation at this site led to suppression of the arrhythmia. Of note, very low voltage and fragmented bipolar signals were recorded at the successful ablation site . On the contrary, the unipolar signal exhibited an initial r-wave with a less steep negative dV/dT as compared with during VT1. VT2 was not inducible by atrial or ventricular stimulation with or without isoproterenol infusion 30 minutes after ablation. The patient remained free from arrhythmias six months after the procedure.Activation mapping of the RVOT revealed the earliest activation site at the posterior septum (\u221223 ms) This case report is suggestive of the presence of myocardial fibers displaying preferential conduction properties from the RCC\u2013LCC commissure to a breakout site at the RVOT.1 Of 202 patients with monomorphic VT or premature ventricular contractions (PVCs) originating from the outflow tract, six patients (3%) showed changes in QRS morphology following RF energy delivery, requiring an additional RF application at a different site, which was often the LCC. Yamada et al. reported that VAs originating from the coronary cusps display preferential conduction to the RVOT and an insulated myocardial fiber across the ventricular outflow septum may exist in these cases.2 Especially, in 25% of patients with VAs of a coronary cusp origin, pacemapping from the RVOT yielded a closer match of the QRS morphology than pacing from the coronary cusp. In these cases, pacemapping identified the preferential breakout site.2 In the study by Shirai et al., a QRS morphology shift following catheter ablation at the earliest activation site was observed in 4% of cases of idiopathic outflow-tract VAs. The shifted VT or PVC demonstrated a distinct ECG QRS pattern supporting the notion that different preferential QRS exit sites within the outflow tract were operative in these cases. After remapping, the earliest activation site of the second VT or PVC moved to a different anatomical structure adjacent to the initial ablation site in 65% of cases, which was most frequently the LVOT region (coronary cusps).Tada et al. initially investigated the prevalence and characteristics of idiopathic outflow-tract ventricular arrhythmias (VAs) with altered QRS morphology following RF catheter ablation.3 An intramural SOO with preferential conduction channels to specific sites of the outflow tract may explain this phenomenon.3 The presence of preferential conduction can be unmasked by ablation at the first earliest activation site when the first preferential exit of the VT/PVC is eliminated.3 Unipolar signals displaying an rS pattern at both the earliest activation sites, as seen in our case, favors the presence of an intramural SOO.The complexity of the myocardial network around the outflow tract with the potential for preferential/alternative conduction and multiple exiting sites has been suggested to explain subtle variations in the QRS morphology of idiopathic outflow-tract VAs following RF ablation.In conclusion, a QRS morphology shift following catheter ablation of idiopathic outflow-tract VAs is not an uncommon phenomenon. Meticulous activation mapping usually reveals the true SOO in an adjacent site, which is more commonly the coronary cusps."} +{"text": "The Mong Cai pig is an indigenous breed and popularly raised as maternal line in northern Vietnam.

The majorchallenges relate to its size heterogeneity and related issues including (1) useof appropriate calibrators (2) standardization of calibration protocols (3)traceability and (4) reporting units. In the UK, results from the current EQAschemes for lipoprotein(a) suggest that there is considerable work required tostandardize lipoprotein(a) measurement. This is becoming increasingly pertinentwith the increasing recognition of lipoprotein(a) as an independent risk factorfor cardiovascular disease in international guidelines and the emergence ofnovel antisense therapies to effectively reduce lipoprotein(a). This articleraises awareness of the importance of measurement of lipoprotein(a) for theassessment of cardiovascular disease risk and gives guidance to clinicallaboratories regarding choice of appropriate assays. Remarkably, Lp(a)plasma concentrations within the population can therefore vary by 1000-fold. Thepathophysiology underpinning Lp(a)\u2019s role in atherosclerosis is thought to be two-fold:12,13 firstly, a pro-thrombotic effect by inhibiting fibrinolysis due to thesequence homology of apo(a) to plasminogen and secondly, a pro-atherogenic effectthrough its ability to accumulate in the intima of arteries. Epidemiological andgenetic data have now confirmed Lp(a) as an independent risk factor for coronaryheart disease, stroke and calcific aortic valve stenosis.1416Composed of an LDL-like particle, in which a single apolipoprotein B100 (apoB) iscovalently linked by a disulphide bond to a single apolipoprotein(a) (apo(a)) , Lp(a) pA personal or family history of premature atherosclerotic cardiovasculardisease (<60 years of age).First degree relatives of those with high Lp(a) plasma concentrations(>200 nmol/L).Familial hypercholesterolaemia (FH), or other genetic forms ofdyslipidaemia.Calcific aortic valve stenosis.A borderline increased (but <15%) 10-year risk of a cardiovascularevent.HEART UK (Hyperlipidaemia Education and Atherosclerosis Research Trust UK) recentlypublished a consensus statement that makes recommendations regarding the use ofLp(a) measurement in clinical practice and also reviews current and emergingtherapeutic strategies to reduce plasma Lp(a) concentrations to decrease risk ofCVD. HEART UK recommends Lp(a) measurement in the following groups: 17 to grade this risk on the basis of percentile distributions as follows:32\u201390\u2009nmol/L minor; 90\u2013200\u2009nmol/L moderate; 200\u2013400\u2009nmol/L high; >400 nmol/L veryhigh. Further studies are required to derive ethnicity-specific ranges, appropriateto the UK population as Lp(a) concentration varies by race/ethnicity.18As plasma concentrations of Lp(a) are predominantly genetically determined, they arerelatively stable over a lifetime. Therefore, Lp(a) may only need to be measuredonce, unless a secondary cause is suspected or a specific treatment is instituted inorder to lower its plasma concentration. The cardiovascular risk conferred by Lp(a)may be graded depending on the lipoprotein(a) particle concentration and HEART UKhave employed data from the ongoing Copenhagen General Population Study19 and over the past two decades the questionable performance of these assayshas hampered the incorporation of Lp(a) measurement into routine clinical practice.20 However, the recent demonstration that the genetic risk of variants in theLPA gene is fully captured by measurement of Lp(a) particlenumbers (expressed in nmol/L) using commercial immunoassays standardized andcalibrated to minimize isoform sensitivity21 shows that reliable methods for assessment of Lipoprotein(a) associated CVDrisk are available on modern high throughput platforms. There is now an urgent needfor assay harmonization to allow reliable clinical decision making.Despite the efforts of the International Federation of Clinical Chemistry (IFCC) todevelop a reference material for standardization of analytical methods (WHO/IFCCSRM-2B), shortcomings of commercially available immunoassays for this complexparticle, primarily due to their sensitivity to apo(a) isoform size variation, havelong been apparent22 The antibodies used against apo(a) are usually polyclonal and cross-reactwith the multiple KIV-2 repeats thereby overestimating Lp(a) plasma concentrationsin individuals with large isoforms and underestimating the concentrations in thosewith small isoforms.22 As a consequence of this bias, the strength of the relationship between Lp(a)and CVD risk has appeared inconsistent and has frequently been underestimated. Morerecent studies using a monoclonal antibody-based ELISA22 assayinsensitive to apo(a) isoform size variability show a consistent positiverelationship between high levels of Lp(a) and CVD, whereas earlier studies usingisoform sensitive assays have missed this important relationship. In particular, twoinfluential epidemiological studies which reported negative results, were repeated using the isoform insensitiveELISA assay and were clearly positive.23 This highlights the importance of using suitable and standardized methods forLp(a) measurement to accurately assess CVD risk.The large heterogeneity in apo(a) size between, as well as within individuals becauseof the inheritance of two different apo(a) alleles, has been a major challenge tothe accurate measurement of Lp(a).10,11 Concerted effort was made by the IFCC to select and characterize a suitablereference material and to develop a multistep standardization protocol to be used bymanufacturers and clinical laboratories. However, traceability to the WHO/IFCCSRM-2B improves assay comparability but does not eliminate the isoform sensitivityof the analytical methods.24 The target value assigned to the reference material is in nanomoles per litreof Lp(a) protein, reflecting a mole for mole interaction of antibody with apo(a).Lp(a) has historically been expressed in mass units (mg/dL) encompassing the mass ofthe entire particle, including the content of apo(a), apoB-100, cholesterol,cholesteryl ester, phospholipid, triglyceride and carbohydrate. This ismetrologically unsound because what is measured by immunoassays is the proteincomponent of Lp(a) and not its lipid and carbohydrate content. Therefore, the mostappropriate units of measurement of Lp(a) are nmol/L. Lp(a) concentrations shouldnot be converted from nmol/L to mg/dL, or vice versa, as all conversion factors areinherently isoform dependent.25Many studies have shown differences between Lp(a) assays.2628 Of the commercially availablemethods measurement are inherently isoform insensitive.methods , theDenCheck that the accuracy of the assay has been certified by the NorthwestLipid Research Laboratory in Seattle making sure the certificationapplies to the specific instrument.Do not convert results to mass units.External quality assurance programs should distribute samples with knownapo(a) isoform composition and Lp(a) values assigned by a methodvalidated to be independent of apo(a) size polymorphism and calibrationtraceable to the WHO/IFCC SRM-2B reference material.External quality assurance samples should cover the clinically meaningfulrange, especially the management threshold range of 90\u2013200 nmol/LWe suggest the following to improve harmonization of Lp(a) assays: In the UK, there is a long way to go with assay harmonization. The vast majority oflaboratories report Lp(a) concentration in mass units , with no22 However, Lp(a) particles have been found to associate noncovalently withtriglyceride-rich lipoproteins which could result in overestimation of Lp(a)measured by immunoassays based on the apo(a) capture/apoB detection approach.22,29 Another approach to circumvent the effect of apo(a) size variability, is thedevelopment of methods that are not antibody-based. Mass spectrometry methods havealso been reported30 or are under development. However, to be of the greatest clinical utility,new assays should provide the same high throughput as the analytical platformscurrently used in clinical labs as this will facilitate a more widespreadmeasurement of Lp(a).There is clearly a need for innovation in the development of isoform insensitiveLp(a) assays. One approach could be a sandwich immunoassay with antibodies detectingthe apoB component of Lp(a) or monoclonal antibodies to apo(a) directed to a uniqueepitope not present in kringle IV type 2.31,32 Currently, lipoprotein apheresis is the only reliable means of achieving asubstantial reduction of plasma Lp(a); however, its use is limited by its high cost,low capacity and lack of accessibility. Injectable antisense oligonucleotidestargeting hepatic LPA RNA have been shown to reduce apo(a)production and apo(a) assembly with apoB, leading to >90% reduction in Lp(a)particle concentrations. These agents are now in Phase 3 trials (NCT04023552) andthe results will confirm whether selective reduction of Lp(a) levels reduces CVrisk. The need for clinical laboratories to deliver timely, accurate andstandardized measurements of this enigmatic lipoprotein has become one of vitalimportance for us all to address.There is now an urgent need for the standardization of Lp(a) assays firstly, to meetgrowing demand with the recognition in international guidelines of this important,largely unmeasured cardiovascular risk factor and secondly, due to the prospect ofnovel treatments to dramatically lower Lp(a)."} +{"text": "We compared indicators of influenza activity in 2020 before and after public health measures were taken to reduce coronavirus disease (COVID-19) with the corresponding indicators from 3 preceding years.

Several studies included samples of athletes practicing different sports. We applied a classification of sport impact based on the study by Groothaussen and Siener that has2 and 6 to 19 h of training per week. Collectively, these observations suggest that the high volume and intensity of training along with low energy availability could be potential risk factors for developing UI in adolescent female athletes.The benefits of sports practice early in life are well established; however, young female athletes are not immune to suffering sport-related injuries or illness . ParticuB\u00f8 and Sundgot-Borgen described that the presence of UI early in life is a strong predictor for UI later in life (ORR of 8.57) ,21. Due Limitations of this review are the small sample size, heterogeneity, and variability of outcome measures as well as the lack of reliable quantitative outcome measures for UI. The selected studies used validated questionnaires to assess urinary symptoms in young athletes. However, these questionnaires were validated in adult populations. More reliable diagnostic outcomes would improve the quality of the studies. In addition, the analysis of co-founding factors specific to the female adolescent athlete such as menstrual cycle and nutritional status would improve the quality of the studies. We recommend the use of the STROBE checklist for risk of bias study assessment to improve the scientific report of these studies and a classification of sport characteristics and impact, which would additionally improve their comparison and assessment. The development and validation of a specific questionnaire for assessing UI symptoms in adolescent females is warranted.UI during exercise and sports is a concern for young female athletes. Our findings highlight a 48.8% prevalence rate among adolescent female athletes where practitioners of high-impact sports show the highest prevalence rates. Given the high prevalence of UI among adolescent female athletes involving impact sports graded 2 and 3, concerted efforts are needed to provide early education and implement prevention measures before young female athletes experience the burden of UI.

Their definition of EZ was an ictal electro-clinical concept based on SEEG recordings. Over the past 50 years, the concept of EZ has evolved due to invention of sophisticated localizing tools.

Nearby cortex (4 of 6 patients) was the most epileptogenic in the presence of a dominant tuber that lacked center-to-rim gradient in EI. Importantly, these results may contribute to development of an effective implantation strategy of intracerebral electrodes in further defining EZ in TSC, as one of the challenges of using SEEG is determining targets and trajectories based on presurgical data and EZ hypothesis.

Additionally, the effects of spiral corrugation in enhancing the nonlinear buckling behavior of spiral corrugated sandwich FGM cylindrical shells are validated and discussed. Due to their excellent thermo-mechanical properties, functionally graded materials (FGMs) have been applied in engineering structures, such as military structures, nuclear reactors, civil engineering structures, and other technology areas . ResearcBased on Love\u2019s shell theory, Arshad et al. ,3,4 studFor corrugated cylindrical shells, some previous studies have focused on experimental and numerical analyses of the mechanical behavior of these structures. Yang et al. establisDue to their excellent load carrying capacity and conformance with manufacturing technology, spiral corrugated cylindrical shells are often used in engineering structures. According to the best of the authors\u2019 knowledge, there is currently no semi-analytical approach for investigating the mechanical behavior of spiral corrugated cylindrical shells made of sandwich FGM surrounded by an elastic foundation. This paper presents a semi-analytical approach for examining the nonlinear buckling responses of spiral corrugated sandwich FGM circular cylindrical shells using a homogenization technique . The spConsider a spiral corrugated sandwich FGM cylindrical shell with an axial length Based on the geometrical calculations, the relation between the angle of corrugation and the number of full waves of corrugation in a loop coil can be established asThe geometrical parameters of the cross section of corrugations The force and moment results of a sandwich cylindrical shell are expressed by applying the homogenization procedure for corrugated structures established by Xia et al. , as(4){The stiffness matrix terms of non-corrugated shells can be determined asBased on the coordinate transformation technique, the force and moment results of the corrugated sandwich FGM shells in the As can be recognized, the spiral corrugated sandwich FGM cylindrical shells are equivalent to the non-corrugated sandwich FGM cylindrical shells with the new stiffness matrix presented in Equation (6).Based on the nonlinear strain\u2013displacement assumption of von Karman and Donnell shell theory, the strains at the mid-plane of non-corrugated sandwich FGM cylindrical shells can be expressed as (9)\u03b5x0=uThe strains across the shell thickness at a distance From Equation (9), the deformation compatibility equation can be directly established asThe nonlinear equilibrium equations of a non-corrugated cylindrical shell based on Donnell shell theory areConsidering the first two equations of Equation (12), a stress function Substituting Equations (6) and (13) into the third equation of (12), the nonlinear equilibrium equation is obtained in a new form, asFrom the constitutive relations of Equation (6), the inverse relations can be established, taking into account Equation (13), asBy substituting Equation (15) into the deformation compatibility Equation (11), the equation can be rewritten asConsider a spiral corrugated sandwich FGM cylindrical shell under external pressure The solution of the deflection satisfying the boundary condition in Equation (17) in an approximate sense can be applied as a three-state form:Clearly, the simply supported boundary conditions in Equation (17) are approximately satisfied.Substituting Equation (18) into Equation (16), the form of the stress function Substituting the solution form of deflection Equation (18) and stress function form Equation (19) into Equation (14) and then performing the Galerkin procedure in the integral domain Unlike the cylindrical panel, the circumferential closed condition in an average sense must be satisfied for all revolution shell types, asUsing Equations (15) and (18), the closed condition Equation (23) becomesEliminating When the nonlinear amplitude of the postbuckling state The critical buckling pressure By using Equations (20)\u2013(22), the maximal deflection of a shell located at The postbuckling curves of spiral corrugated sandwich FGM cylindrical shells can be determined by combining Equation (25) and Equation (27).In this section, the accuracy of the semi-analytical approach presented for the critical buckling pressure of isotropic cylindrical shells and sandwich FGM cylindrical shells under external pressure is compared with the results reported by Shen et al. , Vuong aAs can be seen in 2 and Alumina 2, and the Poisson ratio was assumed to be a constant value of Numerical investigations were performed to predict the nonlinear buckling responses of spiral corrugated sandwich FGM cylindrical shells subjected to external pressure and surrounded by an elastic medium. The sandwich FGM corrugated cylindrical shells with the following geometrical parameters were considered: The effect of elastic foundation moduli is presented in The postbuckling curves of round spiral corrugated sandwich FGM cylindrical shells are shown in The effect of geometrical parameters of corrugation Corrugated sandwich FGM shells are homogenized to non-corrugated sandwich FGM shells;(2)The critical buckling pressure of a corrugated sandwich FGM cylindrical shell is greater than that of a corresponding non-corrugated sandwich FGM cylindrical shell;(3)The geometrical parameters of the cross section of corrugation and the material properties strongly influence the buckling and postbuckling behavior of sandwich FGM cylindrical shells.Some significant results have been obtained as follows:"} +{"text": "RAD51 (rs1801320) and XRCC2 (rs3218536) genes polymorphism having association with colorectal cancer risk. For this reason the aim of this study is to ascertain their interrelation with colorectal cancer occurrence in Bangladeshi population. In case of Bangladeshi population, no report is observed till now showing the genetic variations of A case control study was conducted where 200 colorectal cancer patients and 200 healthy volunteers were figured for this research using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). RAD51 (rs1801320), G/C heterozygous genotype was found significant . On the other hand, G/G genotype was not found statistically significant and significance was observed for GC+GG . In case of XRCC2 (rs3218536), C/T heterozygous genotype was remarked statistically significant . The T/T genotype was not recorded statistically significant but significance found for CT+TT . Moreover, it is found that the risk factor of developing CRC is observed in G/C, C/T heterozygote and GC+GG, CT+TT (heterozygote+ mutant) in RAD51 (rs1801320) and XRCC2(rs3218536) respectively although no significance is observed in case of G/G and T/T mutant. Here, in case of RAD51 (rs1801320) and XRCC2 (rs3218536) genes polymorphism with colorectal cancer risk is observed in Bangladeshi population.So, the association of In Bangladesh, cancer can be said as one of the uppermost reasons of expansion of death and morbidity in the approaching years. According to International Agency for Research on Cancer, in 2030 the death rate will be 13% and it was 7.5% in 2005 which determines the proportion is appraised to be precisely twofold compared to 2005 . Presumption says, by 2040 the figure will be expanded from 18.1 million to 29.5 million. Colorectal cancer is attributed as the most usual malignant tumours affecting the parts of alimentary canal appeared from large intestine due to unusual extension of cells having potential to invade several parts of human body . Depending on the initiating point, these types of cancers can be said either as colon or rectal cancer. Colon cancer is noticed to be identified in two-third cases and remaining one-third as rectal cancer . 75% of CRC can be remarked as sporadic. In tumour development, a part of modification in case of other genes can be observed and the occurrence of ultimate addition of supplementary malicious attributes such as intrusiveness of tissue and the ability to metastasize takes place .Several risk factors related to CRC are individual study of adenomatous polyps, one\u2019s own record of inflammatory bowel disease, genealogical account of colorectal cancer or adenomatous polyps and inherited genetic risk factors, coronary artery disease notably . Familial Adenomatous Polyposis (FAP) as well as Hereditary Non-Polyposis Colorectal Cancer (HNPCC) also called Lynch syndrome are the most frequent inherited conditions and approximately 5 to 10% of CRCs are a sequel of accepted hereditary condition . The probability of colorectal cancer is actively governed by diet where modification in nutritional habits might diminish up to 70% of CRC implication . High meat consumption, diets with high fat specifically animal fats has also been bundled in colorectal cancer continuation . At adolescent period, several aspects like physical inactivity and corpulence, smoking, strong drink consumption are responsible for the starting of colorectal cancer. Evidence shows that continuing regular use of aspirin along with Non-Steroidal Anti-Inflammatory Drugs (NSAIDS) lessen the probability of CRC considerably . 5-fluorouracil (5-FU) capecitabine, oxaliplatin and irinotecan are utilized predominantly in chemotherapy for the patients of CRC. Targeted therapy is regarded as an advanced sector of drug evolution. It is engaged with targeted therapy which consequences from expanded apprehension of the molecular differences necessitated in cancer occurrence. Particular molecules engaged in tumor magnification and development are featured by these drugs having divergent and generally less serious after effects compared to traditional chemotherapy drugs .RAD51 is up regulated in different cancers. Attachment of the DNA with RAD51 protein takes place at the site of a break and encompassed in a protein case which is indispensable introductory step in the restoring operation. RAD51 gene is an extremely protected well-designated DNA repair protein . The scheme of RAD51 along with molecular regulation has not yet been completely confirmed .The protein, indispensable for reconstructing the damaged DNA is formed by instructions provided with RAD51 gene which plays a fundamental role in homologous recombinational repair. It is evident from innumerable studies that XRCC2 (X-ray repair cross complementing 2) is 7q36.1 which is a member of the RAD51-related protein family. Chromosomal fragmentation, translocations and deletions are thought to be repaired by XRCC2. Additionally, this gene is found to be necessitated in the HR repair (HRR) pathway of DNA double-stranded breaks (DSBs). An association between XRCC2 (rs3218536) single-nucleotide polymorphisms (SNPs) and cancer incidence risk are found to be the most common mutation observed by numerous studies . The increment of cancer risk is appeared due to two known epigenetic causes of XRCC2 deficiency. One of them is the XRCC2 exponent methylation and epigenetic repression of XRCC2 by over-expression of EZH2 protein. Depletion of homologous recombinational repair and epigenetic repression of RAD51 paralogues including XRCC2 are accompanied by increased expression of EZH2. Over-expression of EZH2 protein between 40%-75% is found in breast cancer and EZH2 mRNA is up-adjusted, about 7.5-fold .The location of RAD51 (rs1801320) and XRCC2 (rs3218536) genes have been perceived in different ancestral groups. A case-control study on Bangladeshi population was conducted recently where the high risk association between altered gene expression of RAD51 (rs1801320) gene polymorphism and breast cancer development was detected. In different ethnicities, RAD51 (rs1801320) and XRCC2 (rs3218536) gene polymorphisms are certified to be a threat aspect of colorectal cancer and RAD51 (rs1801320) gene polymorphism in breast cancer evolution in Bangladeshi population. A possibility may arise basing on a correlation between RAD51 (rs1801320) and XRCC2 (rs3218536) polymorphisms with colorectal cancer risk in Bangladeshi population. Moreover, no related investigation has been supervised concerning this feasible association in Bangladeshi populace. We, consequently, presume to find out that predictable relationship of RAD51 (rs1801320) and XRCC2(rs3218536) genetic polymorphisms with colorectal cancer risk in Bangladeshi citizenry for the very first time.As a probable element for breast, colorectal, lung, prostate, endometrial as well as gastric cancers both Study populationRAD51 (rs1801320) and XRCC2 (rs3218536) polymorphism with clinic pathological characteristics of patients are mentioned in RAD51 (rs1801320) and XRCC2 (rs3218536) polymorphisms, patients who have primary location of cancer in rectum are found to be more susceptible to have colorectal cancer as statistical significances are observed; RAD51 and XRCC2 and in both cases the p values observed are less than 0.05. No other factors are found to be significantly associated with RAD51 (rs1801320) and XRCC2 (rs3218536) polymorphisms. Approval of the study protocol was done by the ethical committees of the respective hospitals and the research was executed according to the descriptions of Helsinki and its following editions . An informed consent document was signed by each patient and control subject after briefing the motive of the study. The genotyping scrutiny was done in the laboratory of Biotechnology, Faculty of Pharmacy, The University of Asia Pacific, Dhaka-1205, Bangladesh.A case control research was co-ordinated on 200 colorectal cancer patients and 200 healthy volunteers basing on age, weight and sex. Colorectal cancer patients were enlisted from Ahsania Mission Cancer and General Hospital and National Institute of Cancer Research and Hospital (NICRH), Dhaka, Bangladesh. After that, physical analysis of controls were picked by matching age and genetic history to colorectal cancer patients. The age of patients ranged from 13 years to 89 years (mean 51 years). Most of the patients are observed having tumour stages I, II and IV (mostly stage II). Age, sex, diet, weight, BMI, TNM staging, demographic characteristics, lifestyle factors data were stockpiled via interrogations by skilled attendants in presence of specialized doctors. The demographic characteristics of the patients and the controls are presented in Genotyping RAD51 (rs1801320) and XRCC2 (rs3218536), PCR-Restriction Fragment Length Polymorphism (RFLP) approach was applied to genotype. PCR product of 157 bp and 234 bp were obtained for RAD51 (rs1801320) and XRCC2 (rs3218536) SNPs respectively. PCR amplifications conditions are given in RAD51 (rs1801320) was dispatched with BstNI by incubating at 60\u00b0 C for 4 hours which produced two fragments 86 bp and 71 bp in case of G/G allele while for C/C allele it produced only one fragment of 157 bp. Restriction enzyme Hph1 (37\u00b0 C overnight) bisected the T/T allele of XRCC2 (rs3218536) giving two fragments of 147 bp and 87 bp but didn\u2019t divide the C/C allele that is only one fragment 234 bp was observed. These DNA fragments were blemished with ethidium bromide and pictured on 2% agarose gel electrophoresis.Genomic DNA was separated from the blood specimens assembled from all patients by the help of DNA extraction mini kit, Favorgen, Taiwan. Genomic DNA amplification was executed using the predesigned forward and reverse primers. PCR was done by following the standard protocol mentioned in published method . In case of bothStatistical analysisStatistical analyses were carried out using the SPSS software package 13.0 . Mean age for cases and controls was evaluated by using Student\u2019s t-test. Odd ratios (ORs) and the corresponding 95% confidence intervals (CI) calculated by using logistic regression analysis were used to analyse the association between the polymorphic genotypes and CRC risk, based on heterozygous and homozygous comparison models with the wild type genotype served as the reference. Odds ratios of > 1.00 specified a positive risk association and vice versa. P values of < 0.05 were significant. Study populationRAD51 (rs1801320) and XRCC2(rs3218536) with a number of 200 controls. This study included 97 males (%) and 103 females (57.5%) colorectal cancer patients with an average age of 51 and the control group covered 87 males (43.5%) and 113 females (56.5%) with an average age of 47.The study was conducted through 200 patients of RAD51 (rs1801320) polymorphismRAD51 (rs1801320). This population based case-control study was conducted to survey the prevalence of RAD51 polymorphism in Bangladeshi population of CRC patients and normal controls. The genotype frequencies in cases and controls are presented in It was evident after gel electrophoresis that DNA fragment pattern of BstNI digestion of the PCR product was done to recognize the genetic variation at XRCC2 (rs3218536) polymorphismXRCC2 (rs3218536). This population based case-control study was conducted to investigate the prevalence of XRCC2 polymorphism in Bangladeshi population of CRC patients and normal controls. The genotype frequencies in cases and controls are presented in Digestion by Hph1 shows the mutation of RAD51 (rs1801320) and CRC with present study is shown in XRCC2 (rs3218536) and CRC with present study is given in A comparison of previous association studies between HRR) genes have an extremely immediate association with cancer threat. Both RAD51 and XRCC2 proteins are fundamental constituents of DNA double strand breaks (DSBs) reconstruction by HRR. Constructional at the same time functional correspondences are noted between RAD51 and XRCC2 gene . Genomic instability is demonstrated if cell deficient with any of RAD51 or XRCC2 genes products are defective in homologous recombination. The X-ray repair complementing defective repair in Chinese hamster cells 2 (XRCC2) gene plays an important role in the homologous recombination repair (HRR) pathway at the same time can be said a functional member for taking part in tumor progression . Improvement of unrepaired DNA destructions would be conducted by under expression of RAD51 gene. Replication blunders past these destructions would guide to the growth of mutations and cancer.Protein haploinsufficiency regulation by genetic polymorphisms in homologous recombination repair . Another Chinese case control study says that in CRC tissue, the expression of XRCC2 is inflated and notable interdependences are also found among positive XRCC2 expression, tumor size, Dukes\u2019 stage and TNM stage . In case of Australian population, a comparative consequence of the XRCC2 alteration to cancer threat is remarked for members of this family . Another case study on Polish population (Warsaw) also said that the feasible character of XRCC2 gene polymorphism is responsible for neoplastic diseases. Therefore, XRCC2 polymorphisms may take part dominant role in colorectal cancer tumorigenesis, conferring susceptibility to rectal tumors in Polish population . Similar relationship is also observed when studied on English population . The investigation on RAD51 and XRCC2 gene polymorphism was done by being encouraged with strong association between these genes and these gene polymorphisms may be used in several areas in colon cancer management, such as early detection of the carcinogenesis, prediction of tumor biologic behaviour and being a candidate therapeutic target for colon cancer. Evidence is yielded by this study that RAD51 and XRCC2 gene polymorphisms may be risk factors for colon cancer progress . A result of meta-analysis says that the RAD51 135 G/C polymorphism is responsible for increased risk of CRC in total using allele (OR=1.21) and recessive models (OR=1.62). However, XRCC2 rs3218536 A/G was not associated with the risk of CRC in total or in subgroups in that particular study. As claimed by the consequences of meta-analysis, the RAD51 135 G/C polymorphisms might influence colorectal cancer risk . Few reports are also made out regarding the impact of RAD51135G>C in spread of CRC in Asian populations. In a subgroup of population of Kashmir, RAD51135G>C has marked the association with CRC . On the other hand, in case of Iranian population RAD51 135G>C presumably does not impact on CRC susceptibility and other risk factors should be contemplated for furtherance of management potentials of the disease in Iran .Colon carcinoma can occur due to elevated-expression of RAD51 (rs1801320) and XRCC2 (rs3218536) genes have increased probability of colorectal cancer and both genes are significantly associated with colorectal cancer occurrence and further elucidate the relationship of multiple genotypes at the RAD51(rs1801320) and XRCC2 (rs3218536) locus with colorectal cancer occurrence. The outcomes found from our research are harmonious with various prior studies yet corresponding genotyping analysis in more racial communities is still necessary to confirm the association between SNPs and susceptibility to colorectal cancer. Our results confirmed that RAD51 (rs1801320) and XRCC2 (rs3218536) genes helps to recognize the malfunction of these proteins and can lead to successful therapies for colorectal cancer. In this study, it is observed that the risk factor of developing CRC is noticed in G/C, C/T heterozygote and GC+GG, CT+TT (heterozygote+ mutant) in RAD51 (rs1801320) and XRCC2 (rs3218536) respectively but no significance is found in case of G/G and T/T mutant. So, it can be said that a significant association between RAD51 (rs1801320) and XRCC2 (rs3218536) and colorectal cancer development is confirmed in our population. If the study can be conducted by using more samples from different areas, G/G and T/T mutant can also be found significant. However, it is the first study in Bangladesh and with a limited number of cases and controls. Therefore, RAD51(rs1801320) and XRCC2 (rs3218536) genes polymorphism and colorectal cancer risk is an important research area that needs much more attention as some statistically strong risk factors required to be excluded because of a small number of sample and control. It will also reduce the number of injuries or deaths resulting from incorrect or ineffective prescriptions prescribed for cancer patients and tend to integrate into personalized medicine.In summary, studying SNP in"} +{"text": "The 4Ms of an Age-Friendly Health System start with What Matters to the older adult.

Dental safety-net programs included 1) state-sponsored school sealant programs, 2) county-funded public health departments offering dental services, 3) federally qualified health centers offering dental services, and 4) dental hygiene programs providing community dental services. We obtained information on school sealant programs from the Georgia Department of Public Health Oral Health Program , informaOur visualization indicated good allocation of scarce dental public health resources. Of the 131 dental safety-net programs, 88 (67.2%) were in high-need counties, which is twice the number in low-need counties (43 or 32.8%). Many high-need counties, however, did not have dental safety-net programs. Among the 80 high-need counties, 52 had no programs . In high-need areas, programs were more common in the metropolitan Atlanta area than in the rest of the state. This information is important for planning purposes, although the state may not be able to immediately address the problem of dental shortages in nonmetropolitan counties because of resource constraints and the higher cost of serving areas farther away from the State Oral Health Program, which is based in Atlanta.The maps also illustrate the importance of a granular visualization in areas with diverse populations, such as metropolitan areas. If only county levels are used, small pockets of need may be missed, as in Fulton County. Visualization at the census-tract level in Fulton County provides a better assessment of need and targeting.Our mapping technique provides decision makers in Georgia with a visual tool for assessing how well current dental safety-net programs are allocated across the state and identify gaps in resource allocation where needs could be addressed in future program planning.

Standardizing how caregivers\u2019 needs are assessed in healthcare delivery can help clinicians design care plans that take caregivers\u2019 capabilities into account and provide targeted recommendations for caregiver support. Despite the potential of caregiver assessment, little is known about its use in primary care practice. The present study surveyed a national random sample of 1,000 U.S. primary care clinicians to characterize current practices, barriers, and facilitators of caregiver assessment. A total of 231 completed responses were received. A minority of respondents (11%) reported that their practice or clinic had a standardized procedure for caregiver assessment; one in ten (10%) reported that they had personally conducted a caregiver assessment using a standardized instrument in the past year.

Aluminum is considered as the most common metallic element detectable in natural waters, animal, and plant tissues (3) leading to a significant upsurge in both gastrointestinal absorption and urinary elimination of aluminum in exposed individuals (4). The affinity of aluminum to other elements stimulates free radical-mediated reproductive cytotoxicity causing impairment of testicular tissues to both humans and animals (5). Aluminum compounds are widely used as by-products for the manufacture of several household cooking utensils andpharmaceutical drugs (6). Increase in the level of exposure to aluminum-containing products will boost the concentration of this metallic element in different organs thereby causing harmful effects to the well-being of humans (7).In addition, elevated concentrations of Aluminum in human sperm and seminal plasma were observed to decrease sperm viability and motility (8). Testicular Aluminum accumulations cause spermatocyte necrosis and trigger other reproductive toxicity through several mechanisms such as oxidative stress, which ultimately interferes with spermatogenesis and steroidogenesis, bloodtestis barrier, and endocrine disruption (9). The application of nutritional antioxidant supplements has increased over the years to tackle oxidative stress-induced tissue damage since they act as defense regulators and scavengers of reactive oxygen species. Sulforaphane (SFN) is the most active natural products found in crucifers such as broccoli sprout, cabbage, and kale with the potential of lowering the risk of cancer, oxidative stress-induced tissue injury, and age-related diseases (10). SFN possess antiproliferative activities and can effectively halt the initiation and progression of chemically induced tissue damage in animals (11). In addition, SFN has been suggested to have antidiabetic properties for normalizing changes in blood glucose and insulin sensitivity (12-14), and is used in cardiovascular and antihypertensive protection . It has been reported that SFN can promote elimination and detoxification of aflatoxin (17), acetaldehyde (18), methylmercury (19), acrolein (20), benzene, crotonaldehyde (21), and free radicals (22) through the Nrf2-mediated mechanism. Furthermore, some clinical studies have demonstrated the effectiveness of SFN supplements in the prevention and/or improvement of skin erythema (23), autism (24), insulin resistance (13), Helicobacter pylori-infection (25), and liver abnormality (26). SNF also has the ability to cause programmed cell death(apoptosis) and cell cycle arrest linked to their ability to regulate several proteins such as Bcl-2 and Bax family proteins, caspases, p21, cyclins, and cyclin-dependent kinases (27).This study was therefore designed to investigate the ameliorative response of SFN on the histomorphometric and enzymatic antioxidants on Aluminum chloride were obtained from the animal house, Department of Human Anatomy, Ladoke Akintola University of Technology, Ogbomosho. The rats were collected in an isolated cages in the experimental house of the Department of Human Anatomy, Federal University of Technology, Akure.

The SOD activity in the testes was also determined according to the method described by Adelakun and co-workers (31).\u201cThe hormonal levels of testosterone (TT), follicule-Stimulating Hormone (FSH), and Leutenizing Hormone (LH) were measured using available immunoassay (ELISA) kits according to manufacturer's instructions\u201d.\u201cThe testes of the rats were harvested and fixed in Bouin's fluid for 24 hr before being transferred to 70% alcohol for dehydration. The tissues passed through 90% and absolute alcohol and xylene for different durations before being transferred into molten paraffin wax for 1 hr each in an oven at 65\u00b0C for infiltration. The tissues were embedded and serial sections cut on a rotary microtome set at 5 microns were performed. The tissues were picked up with albumenized slides and allowed to dry on hot plates for 2 min. The slides were dewaxed with xylene and passed through absolute alcohol (two changes), 70% alcohol, 50% alcohol, (in that order), and then in water for 5 min. The slides were then stained with Hematoxylin and Eosin, mounted in DPX, and photomicrographs were taken at a magnification of 100 \u201cMorphometric studies were carried out with modification of Akang and co-workers (32). Briefly, four sections per testis and six microscope fields per section were randomly chosen for analysis. Fields were sampled as images captured on a Leica DM750 bright field microscope (Germany) via LAZ software. Volume densities of testicular ingredients were determined by randomly superimposing a transparent grid comprising 35 test points arranged in a quadratic array. Test points falling on a given testis and its ingredients were summed over all fields from all sections. The total number of points hitting on a given ingredient (lumen (EL), epithelium (EE), interstitium (EI)), divided by the total number of points hitting on the testis sections (ET) multiplied by 100 provided an unbiased estimate of its percentage volume density/volume fraction. The estimation of the volumes of seminiferous tubule EE (seminiferous EE) and EI in the testes was done in accordance with Howard & Reed (33) and Baines and co-workers\u201d (34).\u201cThis was carried out according to the method described by Adelakun and co-workers (31).

The exposure of male individual to environmental toxicant is regarded as the channel that results in reduced sperm counts and infertility . Aluminum is considered as the most common metallic element detectable in natural waters, animal, and plant tissues (3). Compounds of Al due to its reactivity with other elements such as Sulphur and chloride are widely used in many products such as storage utensils, household cookware, food additives, toothpaste,and pharmaceuticals (3). The enormous rate of exposure to Al increases the chances of health-related issues to human due to increase metallic concentration in various organs thereby damaging various tissue of the body including testicular tissues of animals and humans (38). Testicular weight is crucial in the evaluation of male fertility test due to its important association in sperm production (39).

For each of 15 game types (12-month time frame), a parallel multiple mediation model was applied to disaggregate bivariate associations of last year game type participation and problem gambling (Problem Gambling Severity Index) by six mediating mechanisms: (1) demographic problem gambling propensity, (2) number of game types played, (3) gambling frequency within the type, (4) maximum gambling frequency across all types beyond, (5) usual spending within the type, (6) maximum usual spending across all types beyond. Games showed two distinct profiles via which mediator they mostly impacted problem gambling: Electronic gaming machines offline, scratch cards offline, live betting online, and poker offline as well as online impacted problem gambling mostly via gambling frequency within, whereas all other types mostly impacted via the number of game types played. The applied mediation models answer the question by which mechanism game types impact problem gambling in a more exhaustive way than previous research.Bivariate associations of problem gambling with participation in particular game types often decrease when adjusting for demographics or consumption behavior . A summary of 14 peer-reviewed studies showed inconsistencies as well as conceptual and methodological challenges. The aim of this study was to expand previous research by a combination of (1) sophisticated feature-engineering, which disaggregates gambling intensity into facets In general, it is a well known fact that problem gamblers tend to invest more time and money into gambling and usually participate in a larger number of games than non-problem gamblers were applied. However, all of them were based on vastly different samples, ranging from the general population of Australia to patrons of two Las Vegas resort casinos Table\u00a0. In addiHowever, in spite of the methodological variations, the core idea of all data analyses was to examine the statistical association of participation in a specific game type and problem gambling. Therefore, participation in individual game types was applied as a predictor of problem gambling outcomes. This was done either in simultaneous model estimation with all game types and other covariates . They also underlined the importance of another construct of overall gambling intensity, the depth of involvement. Exemplary measures of depth of involvement include frequency of gambling across all game types during the last year combined . This further complicates the complex relationship between problem gambling, game types, context, individual predisposition, and behavior .In sum, the partially inconsistent empirical results of previous sophisticated regression-based studies document the complex relationship between gambling behavior and problem gambling as well as the challenges statistical modeling approaches of this relationship face. Hence, it is a major duty for further research (1) to disentangle the complexity of gambling problems and behavior as precisely as possible and (2) to provide a valid groundwork for evidence-based harm reduction measures referring to particular game types and overall gambling behavior in a given population. In a more practical sense, the inconsistent previous results also show that an unbiased evaluation of the impact of participating in particular game types on problem gambling behavior has to consider (1) demographic characteristics of the gambler and (2) his overall gambling behavior depth and breadth of involvement in regression-based models, however, not only results in the aforementioned empirical inconsistencies, but also in several methodological problems: First, the additionally inclusion of measures of overall gambling intensity (breadth or depth of involvement) in a bivariate model that predicts problem gambling by gambling participation in a specific game type only allows for indirect appraisals of the importance of the intensity measure. The extent of the decrease in statistical association of game type and outcome may be indicative for such an indirect appraisal by which a predictor variable X affects an outcome variable Y (problem gambling). In other words, mediation analyses answer the question how a predictor impacts an outcome and provide explicit point estimates and confidence intervals for specific mediating mechanisms of problem increasing gambling behaviors. Particularly this aspect qualifies parallel multiple mediation analysis to compare the importance of different plausible mechanisms within and beyond a game type, which may impact problem gambling.Against this background of empirical inconsistencies and methodological challenges, mediation analyses may solve some of the outlined problems. The core idea of mediation analyses Hayes is to exIt is worth noting that the depicted previous linear-regression models in their current way of application are similar to an old-fashioned approach of mediation analyses, the so called \u201ccausal steps approach\u201d Hayes . The criMoreover, percentile bootstrap estimation of indirect effects and their confidence intervals is able to cope adequately with some bias caused by strongly correlated mediators like in the case of measures of gambling intensity. Neglecting correlated mediators can affect the standard errors of the association of mediator and the outcome of interest . This in turn affects statistical inference with normal-theory-tests for indirect effects no explicit statistical information about the importance and confidence of specific mechanisms probably impacting problem gambling, (2) multicollinearity of gambling behaviors, (3) lack of conceptual clarity]. The proposed gambling consumption mediation model (GCMM) in the following analyses provides a novel analytical framework that includes (1) last year participation in particular game types as dichotomous predictor variable , (2) different proxy measures of gambling involvement (within and beyond the type of interest) as parallel mediators, and (3) a formative index of socio-demographic covariates that commonly increase the risk of problem gambling as another mediator that may pose an additional way via which particular game types impact an (4) outcome of problem gambling. The presented analytical approach of parallel multiple mediator models for each individual game type in the GCMM generates precise information by which specific indirect effect participation in a particular game type increases gambling problems. These empirically confirmed mechanisms can be addressed precisely by evidence-based harm reduction measures. Moreover, the applied mechanisms of the model (demographics or gambling behavior) are (1) founded in current research (Table\u00a0The aim of this study is to provide a new framework of models 2012\u20132019 by Andrew F. Hayes), a syntax oriented supplementary tool for advanced mediation analyses in SPSS and SAS, based on ordinary least squares path analysis .A conceptual map of the applied parallel mediation models for each game type is illustrated in Fig.\u00a0p-level of 5% most game types showed statistically significant changes across the years of the surveys. Only scratch cards offline and sport betting offline showed no significant changes. However, the majority of changes were based only on minuscule effect sizes with Cramer\u2019s\u00a0V values below 0.1.Table\u00a0A small effect emerged for lotto offline with increasing participation from 2007 (75.6%) to 2011 (79.4%) and decreasing participation in 2017 (68.0%). A small effect also emerged for lotto online on an Icelandic website with an increasing participation from 8.7% in 2007 to 10.5% in 2011 and 19.5% in 2017. Moreover, participation in live betting online on Icelandic or foreign websites increased from 0.8% in 2007 to 4.6% in 2017. Also sport betting online on a foreign website increased from 0.2% in 2007 to 1.2% in 2011 and 5.3% in 2017. Poker offline increased from 7.4% in 2007 to 15.5% in 2011 and decreased again to 9.6% in 2017. Participation in bingo offline changed from 8.9% in 2007 to 15.2% in 2011 and 21.1% in 2017. Dividing participation rates of 2017 by rates of 2007 showed that the mean ratio for all 8 offline game types was 1.04 with largest growth values for bingo offline (2.36) and poker offline (1.29). In contrast, the ratio of 2017/2007 prevalence rates for the 7 online game types showed a mean growth rate of 7.06 with largest values for sport betting on foreign websites (24.89), poker online on a foreign website (7.15), live betting on an Icelandic or foreign website (5.85), and other online gambling on foreign websites (4.31).p\u2009\u2264\u20090.05) but minuscule effect sizes (Eta Square\u2009<\u20090.01) for the majority of inspected attributes . The only at least small effects (0.03\u2009\u2265\u2009squared eta\u2009\u2265\u20090.01) emerged for the following attributes: The number of game types involved in increased from a mean of 1.660 in 2007 to 1.921 in 2011 and 1.944 in 2017. Frequency within bingo offline, lotto online on an Icelandic website, sport betting online on foreign websites, and live betting online on Icelandic or foreign websites increased from 2007 to 2017. Usual spending within bingo, lotto online on Icelandic websites, sport betting online on foreign websites, live betting online on Icelandic or foreign websites, and poker offline increased from 2007 to 2017. Usual spending beyond a given game type increased for every game type from 2007 to 2017.Kruskal\u2013Wallis tests of the metric and ordinal variables across the years of the surveys also showed significant within and beyond in many or even all game types. However, all relevant trends showed only small effect sizes between 2007 and 2017. Consequently, treating the entire dataset as one homogeneous population in the following analyses represents a justified step.Model estimates for unstandardized effects and 95%-percentile bootstrap confidence intervals of the parallel multiple mediation models are presented in Tables\u00a0total effects on problem gambling of last year participation in 11 of the 15 game types were of statistical relevance and 10 types were of problem increasing impact . Lotto offline was the only game type with a statistically relevant problem decreasing impact . For several game types the total impact on problem gambling was not statistically relevant: Lotto online on an Icelandic website, sport betting online on a foreign website, bingo offline, and other online gambling on foreign websites (not poker or betting).The Direct effects of game type participation on gambling problems became non significant for 8 of the 15 game types. Statistically relevant problem increasing direct effects of last year participation when simultaneously considering all other mediating impacts were left only for lotto offline, sport betting online on a foreign website, and other online gambling on foreign websites (not poker or betting). Problem decreasing direct effects occurred for sport betting online on an Icelandic website, EGMs offline, scratch cards offline, and poker offline.specific indirect effects (a*b-paths) which provides an effect size and confidence intervals for each mediator, while considering the direct path and all other mediators (indirect paths) within the model simultaneously. The metric of the unstandardized effects is determined by the scales of the X and Y variables (winsorized sum score of gambling problems), which both were similar across all analyzed game types. Hence, the size of the indirect effects is comparable across the mediators.However, total and direct effects are only of minor interest in the parallel mediation analyses at hand that try to answer the following question: By which mediator (gambling behaviors or demographic propensity) is last year participation in game type X impacting gambling problems most severely? This aspect can explicitly be tackled by the quantification of breadth or (2) mostly via frequency within.A close look at the specific indirect effects revealed two distinct profiles of decisive mediators impacting gambling problems within the different game types: (1) mostly via breadth (number of game types involved in). Breadth was the strongest mediating mechanism of gambling behavior on gambling problems for participating in:lotto offline,lotto online on an Icelandic website,betting on sport pools offline,betting on sport pools on an Icelandic website,sport betting offline,sport betting online on an Icelandic website,sport betting online on a foreign website,betting on skill games offline,bingo offline andother online gambling on foreign websites (not poker or betting).Table\u00a0frequency within. Frequency within was the strongest mediating mechanism of gambling behavior on gambling problems for participating in:EGMs offline,scratch cards offline,live betting online on an Icelandic or foreign website,poker offline andpoker online on a foreign website.Table\u00a0The decision about the most important mediating gambling behavior was unequivocal in almost all game types. For several game types there was only one relevant positive indirect effect like breadth for lotto offline or lotto online on an Icelandic website (positive a*b-path). All other mediating mechanisms did not show statistically relevant effects for these two game types or even showed problem decreasing effects such as propensity for lotto offline or online on an Icelandic website (negative a*b-path).But these negative effect sizes did not mean that the mediating path propensity was not associated with gambling problems for individuals that participated in lotto (positive b-path). Rather, the negative effect was the consequence of a negative association of gambling lotto offline and demographic problem gambling propensity (negative a-path). In other words: Individuals who participated in lotto showed a reduced level of demographic propensity for gambling problems . Consequently, the product of a*b for the mediator propensity among individuals participating in lotto offline showed negative effect sizes. Hence, this mediator could not be an important problem increasing mechanism for lotto offline, even if it was positively associated with gambling problems in general.problem reducing impacts were not plausible from a theoretical position . However, in all five depicted situations with statistically relevant negative single b-paths the products of a*b-paths were not statistically relevant. Hayes in the following situations: (1) betting on sport pools online on an Icelandic website via spending within; (2) live betting online on a foreign or Icelandic website via spending within; (3) sport betting online on foreign websites via spending within; (4) other games online (not betting or poker) on a foreign website via frequency within; (5) other games online via usual spending within. These t. Hayes , p. 520 breadth of involvement (10 game types) or (2) via frequency of gambling within that type of interest (5 game types).A simple descriptive rule of thumb to determine the most important mediator among a game type is to divide the largest statistically relevant and positive effect by the second largest relevant and positive effect within a game type . In almost all game types, this ratio was between values of 3.96 (betting on sport pools on an Icelandic website) and 2.20 (live betting online on an Icelandic or foreign website), indicating distinct orders of most important mediating mechanisms (effect size of the most important mediator outperforming the second by at least factor 2 in 14 of 15 game types). The only exception from this order was betting on skill games offline, with a ratio of only 1.64 between the mediators breadth and propensity, indicating a more equivocal profile of most important mediators among this game type. Participation in any other analyzed game type was unequivocally most strongly mediated either via (1) However, the remarkable positions of the two mediators breadth and frequency within for some game types did not disqualify the other mediators in the GCMM as redundant. On the contrary: Propensity and frequency beyond both showed statistically relevant specific indirect effects in 14 of 15 game types, spending beyond in 13 of 15 game types, and spending within in 3 of 15 game types.The presented GCMM provides, for the first time, an analytical frame work to disentangle the complex network of (1) last year participation in particular game types, (2) an outcome of problem gambling and different proxy measures of (3) socio-demographic problem gambling propensity, (4) overall gambling involvement , and (5) game type-specific gambling involvement . The chosen approach of parallel multiple mediation analyses allowed for explicit quantification of the behavioral or interpersonal mechanisms, by which participation in specific game types impacts the outcome of problem gambling. Cohort analyses of the three merged Icelandic surveys warranted treating the empirical dataset as homogeneous population even though the number of used game types increased slightly and online game types showed continuously increasing levels of participation.p-levels within the parallel mediation analyses at hand were not adjusted for multiple testing, in order to uphold statistical power of the first time application of the GCMM. Further research may apply a more confirmative approach of model testing, including model-fit-statistics, but the aim of this study was rather exploratory.A short summary of 14 peer-reviewed regression-based studies outlined inconclusive results as well as methodological and conceptual challenges that can partially be resolved by the chosen approach of parallel multiple mediation analyses for each particular game type with the proposed mediating mechanisms characterizing gambling behavior and demographic problem gambling propensity. The state-of-the-art percentile bootstrap procedure to estimate effects and confidence intervals of mediators is able to cope adequately with unspecified correlated error terms (multicollinearity of mediators), providing robust estimates of indirect effects with adequate errors of type I and II. Inconsistent results of former research may be partially caused by a lack of such robustness and statistical power of very complex models with many highly correlated predictors. Consequently, statistical mediators appears to be conceptually more convincing than the commonly applied regression-based models with many covariates, because gambling behavior in terms of regularity, diversity, and spent money or time may be part of the etiological process of developing gambling-related harms and problems\u2014not only a covariate one has to adjust for statistically.Treating different attributes of problem gambling behavior or propensity as Of course, mediation analyses are mathematically also regression-based, but the product-term a*b to quantify indirect effects provides additional information. Mediation analyses enabled us to quantify effects and confidence intervals to make precise evaluations of the most important mediating mechanisms by which behavior particular game types impact gambling problems. This information is of notable interest for testing competing models or theories Hayes and for within and beyond as well as the number of game types a person was involved in. The applied maximum function to aggregate the beyond variables was chosen to curtail high correlations with the breadth variable, which occur by the alternative sum function across all game types. Further research is needed to make an informed choice about the most appropriate aggregation, because mean or median functions could also be useful proxies. However, the combination of (1) mediation analyses and (2) precise feature-engineering revealed explicit estimates and insights which were mostly concealed or at least only implicit in former research.The outlined analytical potential of mediation analyses was combined with a very elaborate process of feature-engineering for proxy measures of gambling behavior which distinguished mechanisms of demographic propensity, usual spending and frequency frequency within these types and not by the breadth of involvement or any other mediating variable of the model. Interestingly, results support findings of previous studies in which some of these types still showed explanatory power for gambling problems despite lots of other covariates in the models see: Afifi et al. The empirical findings of the GCMM showed that last year participation in (1) EGMs offline, (2) scratch cards offline, (3) live betting online on Icelandic or foreign websites, (4) poker offline, or (5) poker online on foreign websites impacted gambling problems mostly via mechanisms of gambling To our knowledge, the GCMM represents the first analytical approach that provides explicit estimates of indirect effects and confidence intervals of the most important mediating mechanisms of a game type of interest impacting problem gambling. This data-driven information facilitates a valid evaluation of risk increasing mechanisms of game types and complements former evaluation tools impacted gambling problems mostly in a qualitatively distinct way different from the breadth mechanism\u2014namely via gambling frequency within the type of interest. Furthermore, type-specific measures of gambling frequency within EGMs and poker. Obviously, the GCMM has the potential to conceptually support, model and specify a promising line of research on gambling consumption that tries (1) to explicate the dose\u2013response-relationship of gambling intensity and measures of gambling related harm and (2) to establish evidence based thresholds of low-risk gambling intensity by risk-curve- and receiver-operating-characteristic-curve-analyses , supply and access reductions may be effective due to the simple and convincing mechanisms of the total consumption model of game type participation on gambling problems still showed stabile risk increasing or decreasing impacts. For instance, (1) lotto offline, (2) sport betting online on a foreign website, or (3) other online gambling (not betting or poker) on a foreign website showed direct problem increasing impacts. On the contrary, (4) sport betting online on an Icelandic website, (5) EGMs offline, or (6) scratch cards offline or (7) poker offline showed direct problem decreasing impacts (some kind of protective effect). Obviously, the applied mediators of the GCMM were not able to disentangle the complexity of gambling behavior exhaustively and other potential mediators may be at work that can additionally explain direct effects thoroughly. A mediation model which includes all relevant mechanisms will dissolve all direct effects (c\u2032-paths) completely. Hence, future research on mediating mechanisms on problem gambling should include additional variables, for instance psychological or psychiatric attributes or other operationalizations of propensity that include comorbidities or attributes of personality. For example, the problem increasing direct effect of lotto may be attributable to demographics and health related behavior demographic propensity, of which information is available in most monitoring datasets, and via which game type participation may positively impact ascending levels of problem gambling. Therefore, the result section was mainly narrowed to the problem increasing mechanisms, mostly disregarding problem decreasing mechanisms. Further research is needed to elaborate potential beneficial mechanisms or protective factors. Further research should also specify the applied descriptive rule of thumb (ratio of largest and second largest positive indirect effect) to discriminate both emerging mediating profiles (mostly via breadth or via frequency within) by inferential statistics. Moreover, structural equation models could be applied to explicitly include correlated mediators into the statistical model.The focus of the current GCMM was on mechanisms of (1) The aggregation of demographic information into a mediating propensity score allows for precise comparison of the indirect effect sizes of demographics and behavior. However, in other situations applying demographics as covariates or moderators may be more adequate.The analyses at hand treated gambling problems as a continuously ascending scale.

In the Nationally, the most commonly missed opportunity for preventing congenital syphilis was lack of adequate maternal treatment, likely driven by the high numbers of cases in the South, where this missed opportunity was most prevalent. The most common missed opportunities for preventing congenital syphilis differed by geographic region. In the West, a lack of timely prenatal care was the most commonly missed opportunity, and in the Northeast, late identification of seroconversion was the most common. Regional clinical and demographic differences in mothers of infants with congenital syphilis indicate that different populations are at increased risk and might require different interventions. The high proportion of mothers with early syphilis in certain regions signals recent heterosexual transmission and the potential for future increases in congenital syphilis cases if no intervention occurs. The high proportions of symptomatic and stillborn infants in certain regions might be related to early syphilis among their mothers, given that higher rates of vertical transmission and worse infant outcomes are associated with early syphilis during pregnancy and a lack of timely prenatal care (28%), followed by late identification of seroconversions (11%); prevalences of these missed opportunities differ regionally and by race/ethnicity.Halting continued increases in congenital syphilis requires understanding the missed prevention opportunities and implementing tailored interventions based on local experience."} +{"text": "Dementia is arguably the most devastating condition of older adulthood with treatment options still elusive. Alzheimer\u2019s is the most prevalent form of dementia where cognitive deficits relate strongly to underlying brain pathology. However, there exist cases in which cognitive performance does not match the corresponding level of neuropathology. Attempts to explain this phenomenon often include the concept of cognitive reserve (CR), whereby greater CR presumably results in less impairment relative to the extent of pathology early in disease progression but also greater impairment once cognitive symptoms manifest.

Applying the rate constant distribution (RCD) model to the kinetic curves of Cu(II) ion sorption on PAA and PEI cryogels, we have elucidated the difference in sorption/desorption rates and affinity constants of these materials and showed that physical sorption contributed to the Cu(II) uptake by PAA, but not to that by PEI cryogels. It was shown that PAA cryogels had significantly higher selectivity for Cu(II) sorption in the presence of Zn(II) and Cd(II) ions in comparison with that of PEI cryogels, while irreversible sorption of Co(II) ions by PEI can be used for the separation of Ni(II) and Co(II) ions. Using IR and M\u00f6ssbauer spectroscopy, we have demonstrated that strong complexation of Cu(II) ions with PEI significantly affects the in situ formation of Cu(II) ferrocyanide nanosorbents leading to their inefficiency for Cs Taking into account the difference in affinities of PAA and PEI cryogels toward Cu(II) ions, we have investigated how a polymer matrix affects the efficiency of composite sorbents containing Cu(II) ferrocyanide for cesium ion removal.

The column with the composite material (CuFCN/PAA (precipitation) cryogel) was washed with distilled water and used to investigate the dynamics of Cs+ ion sorption and Cs+ uptake in a batch. In situ formation of composites containing CuFCN was performed as follows: PAA and PEI cryogels were saturated with Cu(II) ions under dynamic conditions and washed with distilled water; in a week, 10 mL of 0.01 M K4[Fe(CN)6] solution was fed through the column at a flow rate of 8 BV/h. Finally, the composites were washed with 150 mL of distilled water, removed from the column, and air-dried for investigation of Cs+ uptake in a batch.Composite cryogels containing CuFCN were fabricated by (i) precipitation of ex situ formed CuFCN colloids on PAA-DGEBD 1:8 cryogel, and (ii) in situ formation of CuFCN in PAA-DGEBD 1:6 and PEI-DGEBD 1:4 cryogels. The composite formed by precipitation method was obtained as follows: 0.5 mL of 0.1 M Cu(NO+ ion uptake in a batch was determined as follows: 5 mg of the composite cryogel was shaken for 24 h with 5 mL of CsCl solution containing 20 mgCs/L (pH~6).

He was started with oral valaciclovir 1gm three times daily (TDS) for 7 days and Tab prednisolone 60mg daily for 5 days. Two days after initiation of the treatment vesicular lesions disappeared but neurological examination revealed right-sided grade IV facial nerve palsy. Ramsay Hunt syndrome or Herpes Zoster Oticus is characterized by reactivation of latent varicella zoster virus in the geniculate ganglion and subsequent spread to cranial nerve. The diagnosis is mainly clinical. The facial paralysis seen in Ramsay Hunt syndrome is often more severe with the increased rate of late neural denervation and decrease the chance of complete recovery."} +{"text": "This presentation reports an exploratory study evaluating the effect of Asian Care Training (ACT) Manual on Asian American (AA) caregivers\u2019 care capacity and knowledge growth.

At the end of exposure, ten dams and ten offspring from each group were used for assessment of cell-mediated immunity and a similar number of animals were sacrificed for evaluating the humoral immune response and serum protein profile. Aluminum chloride exposure of dams (G2 & G3) caused significant suppression of both cell mediated and humoral immune responses in the obtained offsprings compared to the control group (G1) without any significant effect on the immune responses of these dams. Moreover, the serum total globulins, albumin/ globulin (A/G) ratio and gamma globulin fraction were significantly decreased in the treated dam\u2019s offsprings compared to the corresponding controls while the serum total protein and all serum protein fractions showed non significant difference between the control and treated dams and between the two treated dam groups themselves.

NGS is a valuable tool in the diagnostics of various forms of cystic kidney diseases. Its results changed the clinically based diagnoses in 16% (n = 5) of the children.Cystic kidney diseases are a very heterogeneous group of chronic kidney diseases. The diagnosis is usually based on clinical and ultrasound characteristics and the final diagnosis is often difficult to be made. Next-generation sequencing (NGS) may help the clinicians to find the correct final diagnosis. The aim of our study was to test the diagnostic yield of NGS and its ability to improve the diagnosis precision in a heterogeneous group of children with cystic kidney diseases. Next-generation sequencing of genes responsible for the formation of cystic kidneys was performed in 31 unrelated patients with various clinically diagnosed cystic kidney diseases gathered at the Department of Pediatrics of Motol University Hospital in Prague between 2013 and 2018. The underlying pathogenic variants were detected in 71% of patients (n = 22), no or only one pathogenic variant was found in 29% of patients (n = 9). The result of NGS correlated with the clinical diagnosis made before the NGS in 55% of patients (n = 17), in the remaining 14 children (45%) the result of NGS revealed another type of cystic kidney disease that was suspected clinically before or did not find causal mutation in suspected genes.

Four children with a clinical diagnosis of ARPKD was diagnosed as having genetically NPHP11 and one patient (28) de novo ADPKD. The clinical and ultrasound picture of ARPKD and NPHP can be similar making the differential diagnosis difficult mainly in children with non-neonatal manifestation in ARPKD and in absence of extra-renal/hepatic manifestation such as eyes or central nervous system abnormalities present in NPHP.

Also, the causing variant could have been filtered out as variant of unknown significance (VUS) as its function is yet unknown or could have been missed by bioinformatic processing.Moreover, a combination of heterozygous mutations in two different ciliopathic recessive (or dominant) genes could theoretically cause a severe cystic kidney disease phenotype as an oligogenic inheritance where variants in different genes modify final phenotype was already described in ciliopathies (reviewed in ), as welAnother possibility for the discrepancy between clinical and genetic diagnosis is that the cystic kidney disease in a given child is non-inherited which is however very rare in pediatric patients especially if manifested in neonatal/infant age.Extra-renal manifestations, such as eye or CNS abnormalities were the best clues for the correct clinical diagnosis of patients with non-ADPKD cystic kidney diseases . NystagmThe strengths of our study are a very well clinical and ultrasound characterization of the patients, the long-term follow-up and the high number of ciliopathy genes in our panel. The genetic diagnosis consisted of several methods of sequencing and CNV detection and thus provided reliable results.

Its results changed the clinical diagnosis in number of the children. The correct final genetic diagnoses enable better management of children with different forms of cystic kidney diseases and provide efficient genetic counseling.S1 Table(PDF)Click here for additional data file.S2 Table(PDF)Click here for additional data file.S3 Table(PDF)Click here for additional data file.S4 Table+, yes; -, no.(PDF)Click here for additional data file."} +{"text": "We conducted a genome-wide association study of 1317 centenarians from the New England Centenarian Study and 2885 controls using >9M genetic variants.

Initially, (p)ppGpp has been discovered as a transcription regulatory molecule as it binds to RNA polymerase and regulates transcriptional gene regulation. During the past decade, several other target proteins of (p)ppGpp have been discovered and as of now, more than 30 proteins have been reported to be regulated by the binding of these two signaling nucleotides. The regulation of diverse biochemical activities by (p)ppGpp requires fine-tuned molecular interactions with various classes of proteins so that it can moderate varied functions. Here we report a structural dynamics of (p)ppGpp in the unbound state using well-defined computational tools and its interactions with target proteins to understand the differential regulation by (p)ppGpp at the molecular level. We carried out replica exchange molecular dynamics simulation studies to enhance sampling of conformations during (p)ppGpp simulation. The detailed comparative analysis of torsion angle conformation of ribose sugar of unbound (p)ppGpp and bound states of (p)ppGpp was carried out. The structural dynamics shows that two linear phosphate chains provide plasticity to (p)ppGpp nucleotides for the binding to diverse proteins. Moreover, the intermolecular interactions between (p)ppGpp and target proteins were characterized through various physicochemical parameters including, hydrogen bonds, van der Waal\u2019s interactions, aromatic stacking, and side chains of interacting residues of proteins. Surprisingly, we observed that interactions of (p)ppGpp to target protein have a consensus binding pattern for a particular functional class of enzymes. For example, the binding of (p)ppGpp to RNA polymerase is significantly different from the binding of (p)ppGpp to the proteins involved in the ribosome biogenesis pathway. Whereas, (p)ppGpp binding to enzymes involved in nucleotide metabolism facilitates the functional regulation through oligomerization. Analysis of these datasets revealed that guanine base-specific contacts are key determinants to discriminate functional class of protein. Altogether, our studies provide significant information to understand the differential interaction pattern of (p)ppGpp to its target and this information may be useful to design antibacterial compounds based on (p)ppGpp analogs.

These nucleotides are synthesized by (p)ppGpp synthetase by transferring pyrophosphate groups from ATP to GDP/GTP to form ppGpp and pppGpp, respectively . There aThe molecular dynamics simulation studies provide structural dynamic information in the solution state of a molecule. Although, glycosidic bond and ribose sugar in the nucleotide structure exhibit conformational flexibility and classical molecular dynamics simulation on nucleotides is challenging because of energy barriers and sampling of conformations are limited. Therefore, Replica Exchange Molecular Dynamics (REMD) simulation was carried out on ppGpp and pppGpp nucleotides in solution states. In REMD, several identical replicas run in parallel at different temperatures and these allow enhanced sampling of high energy conformations. Moreover, these replicas are allowed to swap their states based on Boltzmann-weighted probability at neighboring temperature state. This process is repeated iteratively during the simulation and subsequently enhanced sampling of conformations is achieved at various temperatures.3 for both molecules and upon addition of buffer, the box volume was expanded to 145262 and 150766 \u00c53 for ppGpp and pppGpp, respectively. Negative charges, due to phosphates groups of (p)ppGpp molecule, were neutralized by the addition of 20 mM Mg2+ in the simulation system. The Optimized Potential for Liquid Simulations 3 enhanced (OPLS3e) force field was selected for the simulation ppGpp-protein complexes. The structural alignment was carried out in PyMol using an atom alignment algorithm. The distribution frequency of glycosidic bonds in unbound states of ppGpp and pppGpp were plotted at 300 K simulation pose in Schrodinger. The torsion angle and phase angle values were calculated from Pseudo-Rotational Online Service and Interactive Tool (PROSIT) , 2005.The structures of (p)ppGpp-protein complexes were downloaded from Protein Data Bank (PDB). The PDB ligand code G4P for ppGpp, 0o2, and C1Z for pppGpp was used as a search term to obtain structures of ppGpp-protein and pppGpp-protein complexes, respectively. As shown in Molecular dynamics simulation is one of the most commonly used approaches to understand structural dynamics of biomolecules in solution state . It has 2+ ions during the simulation, yet higher flexibility of phosphate atoms was observed in the RMSF plot. In contrast to (p)ppGpp, the phosphate groups in cyclic messenger nucleotides show lesser flexibility due to the unavailability of free phosphate chains (2 group of guanine ring of (p)ppGpp in REMD simulation. The detailed analysis of molecular properties shows the overall quality and conformational dynamics of (p)ppGpp during the simulation ppGpp were obtained by energy minimization in Maestro. The structural coordinates of bound (p)ppGpp were extracted from structures of (p)ppGpp-protein complexes. The structural alignment of unbound state and bound state of (p)ppGpp shows substantial similarity in the guanine ring region with RMSD of atoms less than one. However, the phosphate chain shows divergence upon structural alignment which is in agreement with our simulation RMSF plot.syn conformation, however, some occurrences were observed in anti conformation. Our results on the frequency distribution of glycosidic conformation in unbound states are similar to those observed in the bound states in the crystal structure. As most of the structures of (p)ppGpp-protein complexes have anti conformation of glycosidic bond except in few cases it was found in syn conformation such as nucleosidase (6GFM) and maximum puckering amplitude (\u03bdmax) which show that ribose sugar adopts north conformation in both states ((p)ppGpp nucleotides exhibit a substantial extent of conformational flexibility because of various rotatable torsion angles present in the structure particularly a ribose ring .

The ribose moiety of (p)ppGpp makes comparatively fewer interactions with protein atoms which may be the consequence of the structural restrain of the ribose ring. Similarly, van der Waal\u2019s interactions were found majorly in the region of the guanine ring of (p)ppGpp ppGpp . The avaBacillus subtilis ppGpp synthetases are apparent (p)ppGpp binding proteins as these enzymes synthesize ppGpp and pppGpp from ATP and GDP/GTP, respectively. However, most of the structures determined so far are in complexes with substrate analogs as these complexes explain the catalytic mechanism. A brief structural review on (p)ppGpp synthetase proteins has been described previously hence cusubtilis ; small as aureus and one mophiles . The (p)2+ ions. Therefore, these interactions are considered as ionic interactions. The observed binding mode of (p)ppGpp to the nucleotide enzymes is similar due to an analogy of substrate nucleotide structure to the (p)ppGpp. As shown in the graph, the N1, N2, N7, and O6 atoms of the aromatic guanine ring of (p)ppGpp is a major contributor to hydrogen bond interaction with protein residues.There are six crystal structures of (p)ppGpp and nucleotide metabolic enzymes complexes available in the Protein Data Bank which includes Xanthine phosphoribosyltransferase (XPRT) , PyrimidThere are five crystal structures of GTP binding GTPase proteins in complex with (p)ppGpp available till now. These include Obg GTP binding protein , GTPase RNA polymerase was the first protein complex reported to regulate its activity by binding of (p)ppGpp . There aThere are several crystal structures of various other functional class of (p)ppGpp binding proteins reported including translation peptide chain release factor 3 (PDB: 3VR1) , acetylt2+) plays a significant role in the structural stability of nucleic acid and nucleotides by neutralizing highly negative charged phosphate groups (2+ ions assist in the specific interaction of (p)ppGpp to their target protein. As shown in the graph ppGpp synthetase, RelTt, it binds to only one chain of phosphate ppGpp but it also mediates interactions between (p)ppGpp and protein side chains. Each phosphate chain of (p)ppGpp is making interactions with one Mg2+ ion in the complex of RNA polymerase-(p)ppGpp. Altogether, we have observed Mg2+ ions in several other complexes of (p)ppGpp-protein structures except for few complexes which may be the limitation of electron density interpretation as discussed earlier ppGpp have linear phosphate chains that provide additional flexibility to adapt various conformations according to the stereochemistry of the binding site of a respective target protein. Overall, our results support the hypothesis that the conformation flexibility of glycosidic bond, ribose sugar puckering, and phosphate groups provide structural plasticity to the (p)ppGpp for binding to the various functional class of proteins. The structures of unbound ppGpp and pppGpp in solution states obtained by MD simulation are similar to that observed in the structures in bound form, hence, these structures resemble biologically active conformations of (p)ppGpp. The gyration conformation profile of glycosidic bond is in agreement with the conformation of (p)ppGpp observed in the bound state. The analysis of (p)ppGpp-protein interactions reveals that the binding pattern of these nucleotides governs the regulation for a particular class of target proteins.The original contributions presented in the study are included in the article/GK and NB conceptualized the study.

ERp57 may become a potential biomarker and therapeutic target to combat cancer development and chemoresistance. Here, we summarize the available knowledge of the role of ERp57 in cancer and the underlying mechanisms.Endoplasmic reticulum resident protein 57 (ERp57) has a molecular weight of 57 kDa, belongs to the protein disulfide-isomerase (PDI) family, and is primarily located in the endoplasmic reticulum (ER). ERp57 functions in the quality control of nascent synthesized glycoproteins, participates in major histocompatibility complex (MHC) class I molecule assembly, regulates immune responses, maintains immunogenic cell death (ICD), regulates the unfolded protein response (UPR), functions as a 1,25-dihydroxy vitamin D With cancer incidence and mortality rates increasing rapidly, cancer has become a global problem and is expected to become the leading cause of death worldwide in the 21st century according to the Global Cancer Statistics 2018 report The PDI family includes more than 20 members that catalyze cysteine-based redox reactions and play critical roles in productive protein folding in vitro analyses and clinical trials support that ERp57 is overexpressed in a variety of cancers. ERp57 expression is significantly different between tumor tissues and normal tissues (P < 0.05) in a wide variety of cancers, including stomach adenocarcinoma, colon adenocarcinoma, liver hepatocellular carcinoma (HCC), breast invasive carcinoma, and prostate adenocarcinoma, as shown in Figure http://ualcan.path.uab.edu/analysis.html) Recent research from In vitro, knockdown of ERp57 in HeLa cells inhibits cancer invasiveness and metastasis Some studies have demonstrated that ERp57 is a primary cellular target that inhibits cancer cell proliferation + T cells is enhanced when ERp57 is knocked out in human CD8+ T cells because ERp57 knockout in CD8+ T cells regulates the expression of multiple immune regulators and effectors on the cell surface + T cells need to be explored in detail to expand the utility of ERp57 in cancer immunotherapy strategies.Calnexin (CNX) and calreticulin (CRT) predominantly act as lectins that specifically interact with nascently synthesized glycoproteins in the ER, and ERp57 forms complexes with these proteins to accomplish efficient folding and proper formation of intramolecular disulfide bonds in glycoproteins in vivo because CRT translocation is inhibited and immunogenic cell death is abolished Immunogenic cell death (ICD), a type of regulated cell death (RCD), induces adaptive immune responses to kill cells directly Due to its disulfide isomerase activity, ERp57 forms a complex with CNX and CRT to specifically modulate the folding of newly synthesized glycoproteins by facilitating the formation of native disulfide bonds Recent data suggest that ERp57 plays an important role in the DNA repair process. ERp57, accompanied by high mobility group proteins 1 and 2 (HMGB1 and HMGB2), acts as a component of a complex that detects damaged DNA, inactivates the mismatch repair system and decreases the sensitivity of cells to thiopurine treatment Taken together, the evidence indicates that ERp57 has a protective effect on the survival of tumor cells due to its contribution to the DNA repair process, which regulates the sensitivity of the tumor to DNA-modifying chemotherapy. Thus, it may become a biomarker to predict therapeutic failure and success. However, further studies are required to confirm these findings and identify potential antitumor targets.2D3 is the active form of vitamin D, and its analogs exert inhibitory effects on the proliferation and progression of multiple cancers, including melanoma 3-membrane-associated, rapid response to steroid binding receptor, mainly located on the plasma membrane and Golgi/ER 2D3 to form a ligand-receptor complex to mediate several rapid signal transduction cascades; for example, it regulates STAT3 2+ release from lysosomes to activate autolysosomal degradation In vitro studies have revealed that knockdown of ERp57 inhibits HCC cell proliferation 1,25(OH)Mitomycin C (MMC) exerts anticancer effects by inducing DNA cross-linking in cancer cells Affymetrix microarray results suggest that cytoskeletal remodeling and the Wnt signaling pathway are the two of the top pathways disrupted by ERp57 silencing in HeLa cells 3-MARRS receptor ERp57 plays an important role in the natural history of cancer and the therapeutic process.

It is the fourth for both incidence and mortality. For cervical cancer, imaging and pathology assessments are incorporated in the revised 2018 Federation of Gynecology and Obstetrics (FIGO) staging system. Uses of imaging techniques for the pre-treatment work-up of cervical cancer have been increasing. Among imaging techniques for the evaluation of cervical cancer, ultrasound is cheaper, faster and widely available than other imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI). Advanced technique in ultrasound, such as three-dimension (3D) ultrasound and color Doppler, have improved the clinical application of ultrasound in cervical cancer. Ultrasound may provide highly accurate information on detecting tumor presence and evaluating local tumor extent if performed by ultrasound-trained gynecologists; the experience of readers is also critical for correct pretreatment staging and assessment of response to treatment. Sonographic images could be useful to predict response of neoadjuvant chemotherapy, radiotherapy, chemotherapy and concurrent chemoradiotherapy in patients with cervical cancer. This review article attempted to present the most updated specific applications of ultrasound in cervical cancer. Cervical cancer is a common gynecologic malignancy among women. It is the fourth for both incidence and mortality in Global cancer statistics 2018 Patient age, performance status, para-aortic lymph node status, tumor size, and pelvic lymph node status are significantly associated with progression-free interval Cervical cancer can spread by lymphatic or hematogenous dissemination or direct extension. Staging cervical cancer is critical for approaching the most effective treatment strategy and predicting the outcomes. Stage IA cancer can be treated with cervical conization procedure or simple hysterectomy, while later stages may require neoadjuvant chemotherapy, radical surgery, radiation, chemotherapy or a combination of therapies. It is valuable to evaluate the response to treatment in cervical cancer women.For cervical cancer, imaging and pathology assessments are incorporated in the revised 2018 F\u00e9d\u00e9ration internationale de gyn\u00e9cologie et d'obst\u00e9trique (FIGO) staging system Transvaginal and transrectal ultrasound (TVUS and TRUS) are typically performed by the gynecologist with the advantage of low cost and wide availability A study enrolled 52 patients, 13 were advanced-stage disease (stage \u2265IIb) and 39 were early-stage disease (stage \u2264IIa), to evaluate the combined use of transvaginal elastography (TVES) and high-resolution TVUS in comparison with the diagnostic performance of magnetic resonance imaging (MRI) in detecting parametrial invasion in cervical cancer. It could be promising and economic for pre-operative work-up of cervical cancer by a dedicated gynecologic radiologist using TVES combined with TVUS In the cases with negative paraaortic lymph nodes on computed tomography (CT) or positron emission tomography (PET-CT), it could be necessary to perform dissection of the paraaortic lymph node in surgical staging. Obtaining an ultrasound or CT-guided tru-cut biopsy in equivocal extrauterine lesion is recommended to reduce false positive findings by imaging methods Hence, uses of imaging techniques for the pre-treatment work-up of cervical cancer have been increasing Among imaging techniques for the evaluation of cervical cancer, ultrasound is faster, radiation-free, cheaper, noninvasive, no contrast medium required and more widely available than other imaging techniques The characteristics of the cervix blood flow in normal women and in women with precancerous lesions or invasive cancers were reported by using three-dimensional power Doppler ultrasound (3D PDU) indices, including the intensity of flow at the time of volume acquisition (FI), the number of vessels within the volume of interest (VI), and both blood flow and vascularization (VFI) TVCD combined with colposcopy was used to diagnose precancerous lesions and early stage cervical cancer A thorough evaluation to determine the extent of cervical cancer should be performed if the diagnosis has been identified. There were several studies involving detection of the extension of cervical cancer lesion Table .The role of ultrasound for staging cervical cancer was reported in early 90s The accuracies of staging with TRUS and clinical staging were 83% and 78%, respectively. The sensitivity, specificity and accuracy of TRUS for extent of parametrial involvement were 78%, 89% and 87%. TRUS could be helpful applied to routine pretreatment assessment of patients with cervical carcinoma In the assessment of parametrial infiltration in cervical cancer, a study included 29 patients using MRI and 2D and 3D ultrasound examination before treatment. The result showed that 2D and 3D ultrasound had similar moderate agreement with MRI. However, 2D and 3D ultrasound examinations are more available at low cost than MRI. Ultrasound could be considered as a method for preoperative work-up of cervical cancer The agreement of clinical examination, 3D and 2D sonography with MRI for local staging of cervical carcinoma was evaluated For evaluating the tumor's volume and intra-tumoral vascularization, the study enrolled 27 patients, with cervical cancer and stage 1B1 disease, who have an initial 2D ultrasound examination and followed by 3D volumes of the cervix. The Virtual Organ Computer Aided Analysis (VOCAL) program was used to calculate the tumor volume and vascularization A recent study reported the local staging of cervical cancer for 46 patients who underwent MRI of the pelvis and high\u2010resolution TVUS A previous prospect study, included 38 cervical cancer patients, involved the TRUS in the evaluation of cervical carcinoma and comparing with spiral computed tomography (SCT) and MRI For locally advanced cervical cancer, 3-dimensional transvaginal ultrasound (3D-TVUS) was used to diagnose the extent of invasive cervical cancer and compare to that of Magnetic resonance imaging For cervical primary tumor confined to the origin, the sonographic detection rate is high; transrectal or TVUS is a highly accurate modality in classifying early-stage tumors The diagnostic performance of TVUS and MRI for assessment of presence and extent of cervical cancer was investigated by a prospective study The diagnostic performance of TVUS examination with regard to local extent and tumor size of the disease of early stage cervical cancer was investigated Assessment of the extension of the lesion has been researched Furthermore, angiogenesis, the formation of new vessels in a specific area, is required for tumor growth and progression Transvaginal Color Doppler in cervical cancer allows non-invasive assessment of tumor angiogenesis Color Doppler findings associated with risk factors was reported by a study involving neoangiogenesis measured in early cervical cancer cases Angiogenic parameters, including subjective assessment of pulsatility index (PI) and the amount of vessels within the tumor (scanty-moderate or abundant), were evaluated by transvaginal color Doppler ultrasound for 27 early stage cervical cancer patients. The risk factors were recorded. Tumors with abundant vasculization were significantly associated with parametrial involvement, lymph-vascular space involvement, pelvic lymph node metastases etc. Postoperative treatment was significantly more prevalent in patients with profuse vascularization The p53 protein expression in cervical cancer after RT correlated with transvaginal color Doppler ultrasound findings was reported by a recent study Several studies have evaluated the role of ultrasound for predicting the response to varied treatment in women with cervical cancer.The role of TVUS in early prediction of pathological response in a large series of locally advanced cervical cancer patients arranged neoadjuvant treatment followed by radical surgery was investigated by using 3D PDU Using Power Doppler vascularity index (PDVI) to predict the response to neoadjuvant chemotherapy (NACT) in bulky early stage cervical carcinoma was reported A prospective study involved 42 women with locally advanced cervical cancer referred for NACT Transvaginal Color Doppler sonography used to predict the response to chemotherapy in patients with advanced cervical cancer was reported The residual tumor in locally advanced cervical cancer patients receiving chemoradiation and radical surgery was assessed by 3D power Doppler, 2D ultrasound parameters, or contrast-enhanced indices Ttransvaginal color Doppler ultrasonography (TCD) used to predict response to preoperative chemoradiation for locally advanced cervical carcinoma patients was investigated Alterations in cervical intra-tumoral vascularization during and after radiotherapy investigated by 3D PDU was reported The evaluation of radiotherapy response of cervical cancer by suing gray scale and color Doppler ultrasonography was report It was reported that Transvaginal color Doppler sonography could be useful in predicting clinical response to concurrent chemoradiation for locally advanced cervical carcinoma The investigation of early response of locally advanced cervical cancer patients undergoing concurrent chemo-radiotherapy (CCRT) by ultrasound was reported The role of intraoperative ultrasound guidance in intracavitary brachytherapy of cervical cancer was investigated in a recent retrospectively study In a recent systematic review and meta-analysis, a decrease of uterine perforations by using ultrasound image-guided applicator insertion for cervical carcinoma patients underwent intracavitary brachytherapy was revealed TRUS guided high dose rate (HDR) interstitial brachytherapy for patients of cervical cancer was investigated For the ability of evaluating morphology and intensity of blood flow, ultrasound technique might be used to improve cervical cancer screening, and this need more studies to confirm the applications. Imaging during the primary diagnostic work-up is essential for accurately assessment of tumor extent and selecting the best therapeutic option for cervical cancer patients. Ultrasound may be a useful modality to evaluate local extent of disease in cervical cancer. This technique is limited for evaluating lymph node status. Tumor vascularization by Doppler ultrasound could be useful for monitoring and predict response to therapy."} +{"text": "The Medication-Related Osteonecrosis of Jaws (MRONJ) diagnosis process and its prevention play a role of great and rising importance, not only on the Quality of Life (QoL) of patients, but also on the decision-making process by the majority of dentists and oral surgeons involved in MRONJ prevention (primary and secondary). The present paper reports the update of the conclusions from the Consensus Conference\u2014held at the Symposium of the Italian Society of Oral Pathology and Medicine (SIPMO) \u2014after the newest recommendations (2020) on MRONJ were published by two scientific societies , written on the inputs of the experts of the Italian Allied Committee on ONJ (IAC-ONJ). The conference focused on the topic of MRONJ, and in particular on the common practices at risk of inappropriateness in MRONJ diagnosis and therapy, as well as on MRONJ prevention and the dental management of patients at risk of MRONJ. It is a matter of cancer and osteometabolic patients that are at risk since being exposed to several drugs with antiresorptive or, more recently, antiangiogenic activities. At the same time, the Conference traced for dentists and oral surgeons some easy applicable indications and procedures to reduce MRONJ onset risk and to diagnose it early. Continuous updating on these issues, so important for the patient community, is recommended. Medication-Related Osteonecrosis of Jaws (MRONJ) and its prevention play a role of great and rising importance, not only on the Quality of Life (QoL) of patients, but also on the decision-making process of the majority of dentists and oral surgeons, involved every day in MRONJ prevention (primary and secondary). The present report illustrates the update of conclusions adopted from the Consensus Conference held at the Symposium of the Italian Society of Oral Pathology and Medicine (SIPMO) on 20 October 2018, in Ancona (IT), when opinions were discussed and synthesized by 24 Italian experts. The Conference was the first national consensus to address the MRONJ disease and specific interventions , it sharThe present report was considered by the experts as convenient and worthwhile in the light of the new findings ,12,13 anThe updated Consensus Conference focused on the common practices still at risk of inappropriateness in MRONJ diagnosis and prevention, and on the dental management of patients exposed to ONJ. It is matter for the cancer and osteometabolic patients, since they are exposed to an increasing number of drugs with antiresorptive or antiangiogenic activities ,16,17,18The experts focused on the topic of MRONJ using the following 6 main subcategories (issues): (1) clinical diagnosis; (2) radiologic diagnosis; (3) primary prevention (before and during drug intake); (4) dental management; (5) drug holiday (temporary suspension vs. therapeutic suspension); and (6) therapy.The IAC-ONJ planned that a recommended practice equivalent will be advised for any inappropriate practice, within these 6 issues.Assume that the Italian Consensus adopted the previously described definition of MRONJ ,5, as be(#1) Restricting the anamnestic interview only to the assumption of bisphosphonates for diagnosing MRONJ.(#2) Carrying out routine bone biopsies when suspecting an MRONJ.(#3) Considering the presence of exposed necrotic bone, in the oral cavity, as an essential (conditio sine qua non) sign to diagnose MRONJ.(#4) Judging the presence of pain as an essential symptom for diagnosing MRONJ.(#5) Believing that all MRONJ are preceded by dental invasive procedures.(#1) Evaluate not only the intake of bisphosphonate drugs (current or past), but also further pharmacological therapies and perform a thorough physical examination and medical history, together with targeted radiologic examinations see (confirm(#2) Perform jaw bone biopsies only if there is a suspicion of metastases in cancer patients (confirmed).(#3) Take into the account not only the presence of exposed necrotic bone but considering also other clinical signs and first/second-level imaging (confirmed).(#4) Consider that the symptom \u201cpain\u201d may not always be present in MRONJ cases, especially in the early stages (confirmed).(#5) Consider that some cases of MRONJ can arise from the presence of dental-periodontal diseases or spontaneously, without any relation to invasive dental procedures (confirmed).Radiologic imaging is assumed to be a fundamental tool for diagnostic completion, defining the extent of the disease at the skeletal level, staging and the correct therapeutic planning. Even if it is well known that no specific radiological signs of disease can be defined until now, an increasing volume of evidence recognizes some radiological characteristics that, although non-specific, are associated with MRONJ ,23,24,25(#1) Starting therapies at risk of ONJ without a radiologic assessment of dental arches, remarkably in cancer patients.(#2) Omitting the radiologic assessment for those patients at risk of MRONJ in the presence of dental/endo-periodontal diseases.(#3) Prescribing to everybody exposed to therapies at risk of ONJ all imaging techniques to rule out MRONJ.(#4) Requiring radiologic exams without a specific diagnostic hypothesis.(#5) Prescribing radiological exams for MRONJ only after onset of jawbone exposure.(#6) Diagnosing MRONJ only on the basis of the clinical signs, without radiologic assessment.(#7) Prescribing high-resolution imaging for soft tissue (with contrast medium) for diagnosis of MRONJ.(#8) Planning MRONJ treatment without second-level imaging exams for assessing jawbone disease extension and severity.(#9) Monitoring the extension of the MRONJ process only by investigations of first-level exams .(#1) Evaluate clinically and radiologically any local risk factors for MRONJ for preventive dental screening in patients, remarkably cancer ones, who are candidates for therapies at higher risk of MRONJ; sometimes, MRONJ could manifest like a dental/endo-periodontal disease, or a worsening of a pre-existent disease (updated) .(#2) Perform radiological exams in all cases of dental/endo-periodontal diseases in patients at risk of MRONJ (confirmed).(#3) Reserve the indication for the execution of radiological exams of the second level to patients at MRONJ risk only in the presence of ascertained clinical or radiologic signs compatible with MRONJ (confirmed) ,9,22.(#4) Specify always the diagnostic hypothesis when prescribing radiological exams of any level in patients at MRONJ risk (confirmed).(#5) Do not delay in prescribing radiologic exams to investigate any clinical signs of possible MRONJ, independent of the presence of bone exposure or fistulas (updated).(#6) Integrate always the clinical check-up with the appropriate imaging exams for the diagnosis of MRONJ (confirmed).(#7) Prescribe radiologic exams for bone diseases without contrast medium for diagnosis of MRONJ (confirmed).(#8) Set up the MRONJ treatment after defining its extension and severity also by targeted imaging (confirmed).(#9) Use targeted imaging to monitor MRONJ during follow-up after conservative and/or surgical treatment (updated).Assuming that recently it has been confirmed that MRONJ prevention means applying the correct protocols of (1) primary prevention for both pre-treatment and in-treatment patients, and (2) secondary prevention , the ConPrimary prevention for MRONJ mainly means elimination/reduction of the oral and dental risk factors ,27,28,29A new emerging and huge aspect is that primary prevention should be performed not only prior to taking the MRONJ-related drugs but also during and after the treatment with antiresorptive agents (AR), in order to eliminate any infective outbreaks of MRONJ. It is the responsibility of the dentist to accurately assess the risk factors leading to the development of MRONJ and suggest a strategy to remove these factors or minimize the risk. The dentist must also stress the importance of maintaining effective dental hygiene , including regular check-ups, for the patient. Both are necessary to maintain oral health, reducing the outbreak of MRONJ and/or detecting possible signs of the early symptoms of this disease.Secondary prevention or early diagnosis is the second pillar in the strategy against MRONJ, since we know that MRONJ diagnosed at an early stage is more likely to be treated successfully. With respect to the diagnostic work-up, the main problem is the possible under-diagnosing of MRONJ cases without bone exposure (or fistula). A recent multicenter study ,30 has d(#1) Keeping teeth with endodontic and/or periodontal diseases at uncertain prognosis only to avoid extractive and invasive procedures, in patients at risk of MRONJ.(#2) Extracting teeth in partial or total inclusion for pure preventive purposes in patients that are candidates for treatment with drugs at risk of inducing MRONJ.(#3) Scheduling in cancer patients the first dental check-up only after diagnosis of bone metastases.(#4) Omitting in osteometabolic patients dental check-ups for oral health status assessment and relative preventive dentistry actions.(#5) Omitting periodic dental check-ups for edentulous patients or wearing removable prostheses, if they are at risk of MRONJ.(#6) Underestimating the usefulness of the imaging performed to evaluate cancer disease extension with respect to MRONJ early diagnosis (and follow-up).(#1) Extract teeth with endodontic and/or periodontal diseases, in patients at risk of MRONJ, when a conservative approach is not possible and a good tooth prognosis is not guaranteed (confirmed).(#2) Maintain teeth in partial or total inclusion, if no sign and/or symptom is present (confirmed).(#3) Schedule in cancer patients the first dental check-up as soon as possible, preferably during the tumor staging process (confirmed).(#4) Consider in osteometabolic patients a potential gradient in MRONJ risk (updated(a) Administration and duration of treatment with MRONJ-related drugs ,6,37,38;(b) Eventual presence of comorbidities and further medical therapies indirectly associated; assess, during the prescription of the MRONJ-associated drugs, the oral health status even by a questionnaire 39]; sc; sc39]; (#5) Schedule preventive dental check-ups even in patients at risk of MRONJ even if edentulous or wearing removable dentures, in order to intercept and correct any injury on the oral mucosa (confirmed).(#6) Research any sign of jawbone alterations in cancer patients, revising the pictures of the imaging investigations already performed to stage the cancer disease, in order to potentially detect eventual early signs of MRONJ, before prescribing further specific imaging (updated).Assume that the Consensus Conference has now adopted the new protocols for dental management in patients at risk of MRONJ, published in the recommendations on MRONJ by the two scientific societies SICMF/SIPMO , in whic(#1) Building an implant rehabilitation in cancer patients who have to take or are taking MRONJ-associated drugs due to advanced cancer disease.(#2) Considering as contraindicated, in an absolute sense, implant rehabilitation in osteometabolic patients taking MRONJ-associated drugs (including cancer patients treated with antiresorptive agents for CTIBL).(#3) Prescribing antibiotic prophylaxis before non-invasive dental therapies.(#4) Performing extractive procedures without removing, even if necessary, the alveolar bone, and plan the healing as a second intention .(#1) Avoid in cancer patients implant rehabilitation and plan non-surgical rehabilitation (confirmed).(#2) Plan implant rehabilitation in osteometabolic patients taking into account the cumulative dose of the drug already taken, the periodontal status, lifestyle , comorbidities and other drugs.

It can mainly mean (1) the temporary and preventative suspension of drug therapy in a patient at risk of MRONJ, before the necessary dental procedures (tooth extraction or jawbone surgery); or (2) the suspension of drug therapy due to a diagnosis of MRONJ, hypothetically finalized to stop or to slow the osteonecrosis process (a practice with scarce literature as support). This document will afford only the first meaning of a \u201cdrug holiday\u201d.It is well known that suspension of drug therapy can create different cost\u2013benefit balances, according also to the type of molecule in those two patient populations.In cancer patients with advanced disease , suspension of antiresorptive drugs has to be decided on the basis of a difficult balance between a possible positive drug effect and a potentially higher risk of a side effect anyway present . Clearly that balance could individually change on the basis of the moment along the patient cancer history and along the drug administration history: hypothetically, in the first months of drug administration for bone metastases or myeloma, the suspension is potentially more harmful for the (lack of reduction of) risk of SRE but less dangerous for the risk of triggering MRONJ; vice versa after two years of antiresorptive administration, for example, the suspension appears less dangerous for the risk of SRE (anyway present) whereas the risk of MRONJ (being higher with longer time and higher cumulative drug dose) might receive maximum benefit from the suspension.(a) -BPs have a long half-life and are able to accumulate in the bone tissue, potentially influencing the post-extractive bone tissue repair. Furthermore, for some largely used BPs , a possible antiangiogenic effect was described in the literature, potentially reducing the soft tissue repair process.

Although notable progress has been made, there remain a number of controversial aspects on MRONJ, especially regarding pathogenesis, diagnosis and treatment.The present paper updated conclusions from the Consensus Conference at the Symposium of Italian Society of Oral Pathology and Medicine (SIPMO) , after the newest recommendations on MRONJ were published in 2020 by two scientific societies , written on the inputs of the experts of Italian Allied Committee on ONJ (IAC-ONJ). Some recommendations were confirmed.We defined six issues of MRONJ and submitted for every issue the current knowledge and the appropriate best practices, in order to improve the management of patients.We highlighted the importance to disclose the appropriate information about MRONJ, and the statements and recommendations presented in this paper might represent a beneficial instrument both at a national and international level to better understand and manage this singular and severe disease.In the absence of clear knowledge on the etiology and given the continuous spread of the application of new target therapies, it will be fundamental to continue the research, to report any cases using new drugs and to clarify by evidence-based medicine all the controversial aspects of MRONJ."} +{"text": "Radiotherapy is an important therapeutic approach to treating malignant tumors of different localization, including brain cancer. Glioblastoma multiforme (GBM) represents the most aggressive brain tumor, which develops relapsed disease during the 1st year after the surgical removal of the primary node, in spite of active adjuvant radiochemotherapy. More and more evidence suggests that the treatment's success might be determined by the balance of expected antitumor effects of the treatment and its non-targeted side effects on the surrounding brain tissue. Radiation-induced damage of the GBM microenvironment might create tumor-susceptible niche facilitating proliferation and invasion of the residual glioma cells and the disease relapse. Understanding of molecular mechanisms of radiation-induced changes in brain ECM might help to reconsider and improve conventional anti-glioblastoma radiotherapy, taking into account the balance between its antitumor and ECM-destructing activities. Although little is currently known about the radiation-induced changes in brain ECM, this review summarizes current knowledge about irradiation effects onto the main components of brain ECM such as proteoglycans, glycosaminoglycans, glycoproteins, and the enzymes responsible for their modification and degradation. Adjuvant chemoradiotherapy with temozolomide is a conventional protocol for the standard treatment for newly diagnosed glioblastoma multiforme (GBM) . Last deRadiotherapy (RT) represents an essential part of this post-surgery GBM treatment, and the current standard usually includes 30 X-ray fractions \u00d7 2 Gy, although multiple non-conventional RT sources and regimens are under active investigation .RT aims to destroy the residual GBM cells at the resection border and prevent the disease relapse, but it has wide biological effects on different molecular and physiological parameters in the irradiated brain tissue as well . NegativAlong with that, RT-induced lymphodepletion and subsequent suppression of immune response contribute to the insufficient efficiency of conventional RT and may be limiting the success of GBM treatment . Also, iAt present, more and more evidence is accumulating showing that TME is actively involved in the molecular fate of GBM tumor-initiating cells and tumor development, and significantly modifies the epigenetic landscape of GBM cells with unknown mechanism . IrradiaThe presented data demonstrate that different components of the GBM TME actively respond to X-ray irradiation, whereas the contribution of extracellular matrix (ECM) to radiation-induced changes in both GBM tumor and normal brain tissue remain much less investigated. The available information on this issue is very scanty and fragmentary, but it may be useful to summarize it in order to outline possible directions for future research in this scientific field.Here, the effects of experimental and clinical irradiation onto key brain ECM components in normal brain tissue and GBM cells/tumors will be reviewed.Proteoglycans (PGs) are the main components of brain ECM and play important roles in normal brain physiology and gliomagenesis . They reA major component of the brain ECM is chondroitin sulfate proteoglycans (CSPGs), which are actively involved in the organization of GBM TME and glioma invasion . The comThe few available data on radiation effects on CSPGs are quite controversial, although expression of CSPG-coding genes has a tendency to be down-regulated in non-tumor tissues and up-regulated in glioma cells or tissues upon X-ray irradiation . Cranial125I) seed results in an increase of NG2 content in the brain tissue. The U251 cells with activated NG2 expression (U251\u2013NG2) were significantly more resistant to 5 Gy irradiation compared to the NG2-negative U251 cells suggesting NG2 as an important prognostic factor for radiotherapy resistance activates the expression of CD44 in these cells is an integral component of any tissue, but it plays a particularly important role in the brain, where it represents a major component of intercellular space .Irradiation effects onto HA remain to be almost uninvestigated. The only study by Yoo et al. demonstrates that irradiation of GBM U87MG cells (2 Gy/day for 3 days) or U87MG orthotopic brain tumors (2.5 Gy/day for 3 days) results in a significant increase of HA content in GBM cell-conditioned medium and experimental tumors, respectively. The increase of HA content in tumor tissue affects the biomechanical tension in the GBM microenvironment and provides pro-invasive extracellular signaling cue due to binding with CD44 receptor and SRC activation sufficient for a mesenchymal shift of GBM cells. These findings suggest an explanation for the frequent brain tumor relapse after radiotherapy .Heparan sulfate proteoglycans (HSPGs) represent one of the main components of the neurogenic niche. Tight involvement of both the polysaccharide heparan sulfate (HS) chains and their degrading enzyme heparanase in the development of the nervous system and growth and invasion of glioma tumors are comprehensively described by Xiong et al. , 45. AmoThere is just fragmentary information on the irradiation effects onto these macromolecules.Experimental irradiation of normal mouse brain (7 Gy in a single dose) did not change expression levels of syndecan-1, glypican-1, and perlecan in short-term period (24\u201372 h) . HoweverDespite the common extracellular glycoproteins not being much abundant in brain tissue, they are intrinsic components of brain ECM. Radiation-induced changes in their expression contribute to pathological brain ECM reorganization during radiotherapy.Whole-brain irradiation of experimental animals (a single dose of 10 Gy for rats or 8 fractions \u00d7 5 Gy for 4 weeks for mice) decreases collagen IV content in brain tissue by 24 h after irradiation, while no significant changes are shown at 4 or 8 h after irradiation. Simultaneous up-regulation of expression and enzymatic activity of MMP2 and MMP9 seems to be a molecular mechanism for irradiation-induces ECM degradation .Long-term effects (6 months) of irradiation of the whole brain of Rhesus macaques (age 6\u201311 years), which had received 40 Gy , increased expression of fibronectin 1 (FN1) in brain tissue at mRNA level and protIrradiation of U87 GBM cells (2 Gy/day for 3 days) does not affect the expression of collagen type-I alpha 1 (COL1A1) and collagen type III alpha 1 (COL3A1) .Brain ECM structure is tightly determined by a complex interplay between the expression of ECM glycoproteins/PGs/GAGs and their proteolytic remodeling by matrix metalloproteinases (MMPs) and GAG-degrading enzymes , 48. RadX-ray irradiation of animal brain results in a quick (4\u201324 h) up-regulation of expression and enzymatic activity of MMPs: MMP2 and MMP9 and MMP2 . IrradiaIrradiation of U87MG GBM cells at 2\u20136 Gy doses increases expression and enzymatic activity of MMP2 in these cells and experimental orthotopic U87 tumors obtained from them . This reHeparanase (HPSE) is the main enzyme responsible for the degradation of polysaccharide chains of HS at the cell surface and ECM of all tissues. It involved in normal physiology and pathological reorganization of ECM into TME and cancer progression and metastasis , 45, 49.Gamma-irradiation of brain microvessel endothelial cells results in a significant increase in the release of heparanase, which degrades [35S]-labeled heparan sulfate from the subendothelial matrix. This was most pronounced at the 24 h after irradiation and can affect the interactions of tumor cells with endothelial cells and their microenvironment, which in turn facilitate the formation of metastasis in irradiated tissues . The relAccording to the presented data, X-ray radiation affects all key components of normal brain ECM in different extent and directions .An interesting observation is that radiation has a much pronounced effect on normal brain tissue than on tumor cells. There is a common tendency to the increased expression of glycoproteins (collagen and fibronectin) and decreased expression of main proteoglycan components of brain ECM indicating significant changes of normal structure of brain ECM . ReplaceOn the other side, GBM cells and tumors demonstrate more resistant phenotype to X-ray irradiation and completely different pattern of radiation-induced changes. Only three of fifteen ECM components respond to irradiation by activation of their expression/content . The cooThese radiation-induced changes in brain ECM and the residual GBM cells cooperate to provide a favorable microenvironment for GBM progression. Moreover, multiple studies show that radiotherapy not only serves as a therapeutic mean to eliminate glioma cells but also activates proliferation and invasion of those cells which survived irradiation. This seems to occur due to the selection of radioresistant GBM clones and their active invasion in previously irradiated GBM tumor microenvironment .in vivo, possibly through the imbalance between MMP2 and TIMP2 and ECM degradation (Molecular mechanisms of negative side effects of irradiation are tightly related to GBM TME: subcurative irradiation of primary human GBM tumors in rat brain results in the increased proliferation (3-fold), migration, and invasion of the survived GBM cells associated with increased expression of CD44 and activation of MMP2 expression ; irradiaradation . Besidesradation .Radiation induces also significant changes in immune components of brain microenvironment, which contributes to poor efficacy of anti-GBM radiochemotherapy. Irradiation results in activation of the expression of immune-associated genes in murine glioma and human glioma U87 cell line, leading to changes in immune microenvironment, glioma cells radioresistance, and treatment failure .

While institutions planned for an explicit and systematic approach to resource allocation in crisis settings, this approach did not address many challenges encountered by frontline clinicians, leaving them to struggle with what constituted acceptable standards of care and to make difficult allocation decisions.The findings of this study suggest that expanding the scope of institutional planning to address a broader spectrum of resource limitation may help to support clinicians, promote equity, and optimize care during the pandemic. This qualitative study describes the perspectives and experiences of clinicians involved in institutional planning for resource limitation and/or patient care during the coronavirus disease 2019 (COVID-19) pandemic. Little is known about how US clinicians have responded to resource limitation during the coronavirus disease 2019 (COVID-19) pandemic.To describe the perspectives and experiences of clinicians involved in institutional planning for resource limitation and/or patient care during the pandemic.This qualitative study used inductive thematic analysis of semistructured interviews conducted in April and May 2020 with a national group of clinicians involved in institutional planning and/or clinical care during the COVID-19 pandemic across the United States.Emergent themes describing clinicians\u2019 experience providing care in settings of resource limitation.The 61 participants included in this study were practicing in 15 US states and were more heavily sampled from areas with the highest rates of COVID-19 infection at the time of interviews . Most participants were White individuals (39 [65%]), were attending physicians (45 [75%]), and were practicing in large academic centers . Three overlapping and interrelated themes emerged from qualitative analysis, as follows: (1) planning for crisis capacity, (2) adapting to resource limitation, and (3) multiple unprecedented barriers to care delivery. Clinician leaders worked within their institutions to plan a systematic approach for fair allocation of limited resources in crisis settings so that frontline clinicians would not have to make rationing decisions at the bedside. However, even before a declaration of crisis capacity, clinicians encountered varied and sometimes unanticipated forms of resource limitation that could compromise care, require that they make difficult allocation decisions, and contribute to moral distress. Furthermore, unprecedented challenges to caring for patients during the pandemic, including the need to limit in-person interactions, the rapid pace of change, and the dearth of scientific evidence, added to the challenges of caring for patients and communicating with families.The findings of this qualitative study highlighted the complexity of providing high-quality care for patients during the COVID-19 pandemic. Expanding the scope of institutional planning to address resource limitation challenges that can arise long before declarations of crisis capacity may help to support frontline clinicians, promote equity, and optimize care as the pandemic evolves. Early reports from frontline clinicians in global epicenters describing extreme shortages and bedside rationing of ventilators and intensive care unit (ICU) beds2 prompted a national conversation about how to respond to similar challenges in the United States.3 Hospitals and health care systems drew on frameworks developed by the Institute of Medicine (IOM) and other national organizations to guide care in resource-limited emergency settings.7Since the first US case of coronavirus disease 2019 (COVID-19) was diagnosed in mid-January 2020,8 Under crisis standards of care, a specialized triage team becomes responsible for rationing scarce resources and making decisions about which patients will and will not receive potentially life-saving treatments.Under the IOM\u2019s framework, resource allocation is intentionally siloed from other aspects of clinical care to ensure a fair process and spare frontline clinicians from the responsibility of having to ration scarce resources at the bedside. The IOM recommends a phased adaptation to resource limitation. Institutions first shift from conventional to contingency capacity, in which resources are adapted, optimized, and redistributed to maintain a standard of care that is functionally equivalent to usual care. If resources become so limited that a functionally equivalent standard of care can no longer be sustained, institutions then shift to crisis capacity, and care is redirected to provide the greatest aggregate benefit to the population.10 and has been iteratively refined through ethical analysis8 and community deliberation,12 there have been few opportunities to test the framework in real-world clinical settings. Reports from past pandemics14 and from early global epicenters of the COVID-19 pandemic,15 press reports,17 and perspectives published in the scientific literature19 describe some of the challenges faced by frontline clinicians. However, there is little empirical work describing the experiences and perspectives of US clinicians pertaining to resource limitation and clinical care during the COVID-19 pandemic.21 To address this knowledge gap, we conducted a qualitative analysis of interviews with US clinicians during the pandemic.Although the IOM framework reflects lessons learned during earlier pandemicsCOREQ) reporting guideline at our own institution (the University of Washington). We then expanded recruitment to include other groups of clinicians and those practicing in other parts of the country. We used a snowballing recruitment strategy in which we asked participants to identify colleagues with relevant experience who might be interested in participating in the study. We did not exclude participants who had collegiate relationships with members of the research team. Interviews were conducted between April 9, 2020, and May 26, 2020. The University of Washington institutional review board approved this study and authorized verbal in lieu of written consent. Verbal consent was obtained from all participants. We report details of our methods using the Consolidated Criteria for Reporting Qualitative Research .

A semistructured interview guide independently reviewed and openly coded transcripts until reaching thematic saturation ,25 which occurred after reviewing 30 interview transcripts. One of us (C.R.B.) coded all remaining transcripts for concurrence. Throughout the analysis, the 2 investigators iteratively reviewed codes, collapsed codes into groups with related meanings and relationships, and developed larger thematic categories, returning frequently to the transcripts to ensure that emergent themes were well-grounded in the data.25 All coauthors reviewed example quotations and themes and together developed the final thematic schema. We used Atlas.ti version 8 (Scientific Software Development GmbH) to organize and store text and codes.We conducted an inductive thematic analysis26 All but 1 participant completed the online survey. The mean (SD) age of participants was 46 (11) years, and most were White (39 [65%]), were attending physicians (45 [75%]), and were practicing in large academic hospitals .

Among those who agreed to participate, we purposively sampled 61 clinicians to participate in interviews from April 9, 2020, to May 26, 2020 .26 All bThree overlapping and interrelated themes pertaining to resource limitation and clinical care during the COVID-19 pandemic emerged from qualitative analysis, as follows: (1) planning for crisis capacity, (2) adapting to resource limitation, and (3) multiple unprecedented barriers to care delivery. Exemplar quotations are referenced in parenthesis and listed in Institutional leaders who participated in planning for crisis capacity described the challenges of adapting and operationalizing existing guidelines as well as the substantial moral weight of the task. They were relieved when it became clear that these processes would likely not be needed at their institutions .Clinicians who were involved in institutional planning described strong institutional support for their work to develop protocols to guide care should their region reach crisis capacity (quotation 1). They believed that establishing protocols in advance would allow for a more carefully considered approach (quotation 2) and would be reassuring to staff (quotation 3).Their work involved developing actionable triage algorithms based on existing frameworks (quotation 4). Group deliberation focused on both big picture ethical questions (quotation 5) as well as more granular operational details (quotation 6). Several clinicians with whom we spoke were not formally involved in institutional planning efforts but had offered input and/or developed their own protocols when they identified gaps in planning or disagreed with institutional policies (quotations 7 and 8).To support fairness and avoid bias, the plan was for triage team members to receive very limited information about individual patients when making selection decisions (quotation 9). Some clinicians involved in planning were skeptical about the feasibility of making triage decisions in the absence of detailed clinical information (quotation 10). Others expressed uncertainty about whether and how triage protocols would address more ambiguous or dynamic types of resource limitation (quotation 11). Clinicians could also be mindful of how their work might be viewed by other clinicians and the public (quotation 12) and were wary of sharing details about committee deliberations (quotation 13), plans (quotation 14), or team membership (quotation 15) with their colleagues and/or during the research interview.Clinicians who had been appointed to triage teams were usually respected leaders in intensive care, palliative care, or bioethics who were recognized for their ability to collaborate and communicate (quotation 16). Some of the intensivists and ethicists with whom we spoke saw the work of the triage team as an extension of their usual work (quotations 17 and 18), but many clinicians saw this experience as entirely new (quotation 19). Clinicians described being motivated to participate in the triage team out of a sense of duty and desire to contribute (quotation 20) but were also cognizant of the moral weight and emotional burden of the task before them (quotation 21).Clinicians involved in triage planning understood the processes they were developing to be intended exclusively for crisis settings (quotations 22 and 23) and saw the importance of optimizing resources under contingency capacity to avoid having to resort to crisis standards of care (quotation 24). While several clinicians described a period of intense planning early in the pandemic, by the time of our interviews, many were relieved to report that crisis standards of care were unlikely to be invoked at their institutions, and some had paused or disengaged from triage planning (quotations 25 and 26).Clinicians working during the pandemic were forced to grapple with multiple expected and unexpected forms of resource limitation that did not rise to the level of triggering crisis capacity. Nevertheless, these limitations could compromise care, require that they make difficult allocation decisions, and engender moral distress .Although none of the clinicians with whom we spoke reported a shift to crisis capacity at their institutions, they nevertheless described being faced with a range of expected and unexpected forms of resource limitation (quotation 27) that could arise in a haphazard manner with little warning (quotation 28). Some expressed frustration that resource shortages they were seeing in practice were not acknowledged as such by hospital or regional leadership (quotations 29 and 30) or felt unsupported by colleagues at neighboring medical centers (quotation 31). When not available from their institutions, some clinicians resorted to obtaining health care equipment through personal contacts or even fabricated it themselves (quotations 32 and 33).Clinicians were strongly motivated to avoid situations in which they would have to categorically deny needed treatment to any patient (quotation 34) and went to great lengths to develop alternative treatment options (quotation 35). This might involve using unorthodox therapies or nontraditional approaches to care delivery that could be suboptimal or potentially harmful (quotations 36 and 37). For example, some nephrologists described triaging patients for hemodialysis based on immediate need (quotations 38 and 39), delaying dialysis until there was an emergent indication (quotation 40), and/or prescribing shorter treatment times. As 1 clinician explained, \u201ceveryone gets a little bit of bad care\u201d (quotation 41). Rarely, clinicians were able to draw a clear line between acceptable and unacceptable care (quotation 42), but most focused on doing the best they could under the circumstances (quotation 43).The notion of rationing generally had negative connotations (quotation 44), and some clinicians even described erring on the side of providing more intensive interventions to avoid the appearance of rationing (quotation 45). With rare exceptions (quotation 46), clinicians did not explicitly speak of having had to ration health care resources (quotation 47). Nonetheless, some clinicians did describe situations in which they had to make difficult choices about which patients would and would not receive life-saving therapies, typically on the basis of age and/or comorbidity. This was often seen as part of the spectrum of normal clinical decision-making (quotations 48 and 49) and within their scope of practice (quotation 50). Some clinicians did describe struggling to understand what constituted acceptable practice vs rationing (quotations 51 and 52) and expressed misgivings about the approach to selecting patients for life-saving treatments during the pandemic (quotations 53 and 54).Many clinicians were fearful of having to ration resources (quotation 55). Even in lower acuity and outpatient settings, some struggled with whether it was acceptable to provide suboptimal care (quotation 56) and worried about the potential harms of disrupted care practices (quotation 57). A sense of responsibility for poor outcomes could take a substantial emotional toll (quotation 58). Some clinicians felt that explicit guidelines would be helpful in limiting this moral distress (quotation 59), while others felt personally responsible for poor outcomes regardless of whether they were adhering to institutional recommendations or requirements (quotation 60).Clinicians described multiple barriers to care delivery during the pandemic. These challenges compounded and were difficult to disentangle from the effects of resource limitation .Policies and practices were modified to limit physical interaction between staff, patients, and family members with the dual goals of reducing viral spread and conserving personal protective equipment. While necessary, policies to limit contact with patients were seen as being detrimental to care and to the experiences of both patients and clinicians (quotations 61 and 62). Decisions about something as routine as whether to perform a physical examination could expose tensions around the conflicting goals of conserving scarce resources, protecting oneself, and caring for patients (quotations 63 and 64). Visitor restrictions could complicate and disrupt the process of engaging family members in decision-making (quotations 65 and 66).The rapid pace of change and limited scientific understanding of COVID-19 (quotations 67 and 68) led to substantial uncertainty in day-to-day practice. A sense of desperation and a desire to do everything possible to save lives might lead to more aggressive treatment practices and/or greater willingness to try unproven therapies (quotation 69), reluctance to engage palliative care specialists (quotation 70), and delays in end-of-life decision-making (quotation 71).Many clinicians commented that families and patients were often quite understanding of care disruption (quotation 72), and that they were surprised at how accepting some families could be when care was compromised by the need to conserve resources and/or protect clinicians (quotations 73 and 74). However, some clinicians did describe contentious interactions with family members (quotation 75) and patients (quotation 76) who felt that care was being inappropriately withheld. Other clinicians described deliberately avoiding mention of resource limitation when talking with families (quotation 77).30 the clinicians we interviewed described how, even in the absence of formal declarations of crisis capacity, a variety of expected and unexpected forms of resource limitations severely compromised care and required that they make difficult allocation decisions at the bedside.Our thematic analysis of interviews with US clinicians who were directly involved in patient care and/or strategic planning during the COVID-19 pandemic highlights the real-world complexity of adaptation to resource limitation. Clinicians described patterns of institutional planning that mirrored the IOM\u2019s phased approach, which assumes a common understanding about what constitutes usual standards of care with a plan for a coordinated regional response when these become untenable. However, consistent with prior anecdotal reports,31 and may not be supported by societal priorities for fairness in resource allocation.35Clinicians and clinical teams went to great lengths to develop alternative treatment options and to stretch existing resources to provide at least some care to all in need and avoid having to categorically deny treatment to any patient. However, this approach could mean providing care that fell far short of the IOM standard of functional equivalence to usual care. When substituting lower-quality or delayed treatments, clinicians and clinical teams were left to grapple with what constituted an acceptable standard of care, which could be a source of self-doubt and moral distress. While most clinicians did not feel that they had been in the position of having to ration scarce resources, some nevertheless described practices, such as selection by age or comorbidity, that may be subject to implicit biases7 represent an important step toward promoting fairness through transparent allocation processes.36 However, our results suggest that a narrow focus on crisis capacity may fail to address the full spectrum and complexity of challenges to providing high-quality care encountered by frontline clinicians during the COVID-19 pandemic .In this qualitative study, many clinicians described institutional planning for crisis capacity, but this did not always address real-world challenges to providing care when resources were limited. Expanding the scope of institutional planning beyond crisis capacity may be helpful in supporting clinicians and addressing moral distress, promoting equity, and optimizing care as the pandemic evolves."} +{"text": "Shortening of the hospital stay in patients admitted with the diagnosis of acute myocardial infarction (AMI) has been observed within the last decades.

It is designed to be a part of the standards of patient\u2019s care, to investigate and improve quality of AMI management and outcomes among a diverse population; general and cath consents were taken and has received approval of the ethics committee/institutional review board of our institution.As mentioned earlier, our center is the only cardiac center in Makkah with cath lab facilities, which provides invasive management of AMI, and we envisage capturing almost all AMI patients suitable for invasive management. Every year, our center receives about 1000 AMI patients; a quarter of them were admitted during the hot season in Makkah (2\u20133\u2009weeks of hajj). Our study population included residence and hajj patients . They were referred either from other primary, secondary, and Al-Mashaer hospitals or presented directly through our emergency department, and underwent coronary angiogram and PCI with drug eluting stents.All patients admitted with established diagnosis of AMI during the few weeks of hajj seasons 2018 and 2019.Patients presenting with AMI where coronary angiography was not done because of preference of the patient or due to any other reason and AMI patients admitted outside hajj seasons were not included as well.Demographics.

Categorical data were given as a percentage and compared with a Chi-square test. A P value <\u20090.05 was considered statistically significant.Statistical analysis was performed by the use of the SPSS software package ; version 21.0. Continuous data were expressed as mean \u00b1 SD and compared using the Student Out of 1972 AMI consecutive patients, five hundred fifty seven were treated with PCI during their admission in our center within the two hajj seasons (2\u20133\u2009weeks of hajj) of the 2 consecutive years 2018 and 2019, respectively. Patients were distributed in to two groups: group I, 310 (56%) who were fulfilled the given early discharge criteria and discharged, and group II, 247 (44%) who were discharged late (after 72\u2009h). From the whole discharged AMI patients in the study period, 89 (16%) were discharged within 24\u2009h and 221 (40%) were discharged within 48\u201372\u2009h from admission. One hundred twenty patients (39%) were early discharged in the hajj season 2018 while 190 (61%) were early discharged in the hajj season 2019 . They also showed less prevalence of DM (161 (52%) vs 148 (60%)), HTN (181 (58%) vs 158 (64%)), history of ischemic heart disease (55 (17%) vs 53 (21%)), and previous coronary revasculrization (27 (9%) vs 34 (14%)) compared to group II patients and 212 (68%) vs 87 (35%) and 146 (59%); P = 0.04). The early discharged patients had better hospital outcomes compared to the other group as they showed less prevalence of post myocardial infarction pulmonary edema (5 (2%) vs 15 (6%); P = 0.006) and higher LVEF . Otherwise, regarding the other treatment modalities, there were no detected significant differences between the two groups for the use of thrombolytic therapy and/or tirofiban post AMI treated with PCI.As shown in Table P = 0.003). Also, patients of group I with early discharge had favorable coronary artery disease anatomy as they showed less prevalence of both left main and three vessel disease in their coronary angiography compared to those of group II (7 (2%)and 55 (17%) vs 17 (7%) and 65 (26%); P = 0.01 and 0.02, respectively) vs 171 (69%); Among 310 early discharged patients, only 187 (60%) could be contacted by phone (with help of many translators of different languages) for follow-up within 15\u2009days from the discharge date. They were questioned and found that 177 (95%) patients were totally asymptomatic, 6 (3%) had nonspecific chest pain which did not require any hospitalization, 2 (1%) had minor bleeding (epistaxis resolved spontaneously), and 2 (1%) re-admitted with heart failure symptoms. Those two patients re-admitted with heart failure had been found to have low ejection fractions with ischemic mild to moderate mitral regurge in their pre-discharge echocardiography and their follow-up echocardiography showed the same findings; however, they had mild chest infection, which predisposed to aggravation of heart failure vs 6 (2%), respectively) Fig. . No recoThe overview of most of literature investigating the issue of safety and feasibility of early discharge in AMI patients shows variable methodology and this explains that guidelines for early discharge are based just on limited data derived from randomized trials. The issue of early discharge was investigated in PRAGUE 5 study, which after pilot phase randomized 56 low-risk probands with STEMI, discharged even the next day after successful PCI. It was the first study in which mean length of hospital stay was shorter than 72\u2009h . Most ofIt has been proven that substantial reduction in-hospital length of stay has been associated with reduction of in-hospital charge with no Our center is the only cardiac center in the region providing tertiary care facilities and receives a huge number of AMI patients especially during the 2 to 3\u2009weeks of hajj seasons, subsequently this puts a big burden for the required provided service and hospital costs. The primary aim of our study is to create and implement successful safe early discharge program to improve bed\u2019s utilization efficiency and provide the best, safe, and maximum service for cardiac patients during over crowdedness of the hajj season. To the best of our knowledge, there are no similar studies conducted in our region concerned with this idea. We selected few weeks of each hajj season to conduct this study for many reasons: First, as previously mentioned, our cardiac center is the only center in the region of Makkah that has cath lab facilities and this required to provide tremendous tertiary care services to pilgrims and residents of Makkah during hajj season. Therefore, appropriate improvement of bed utilization is crucial with subsequent increase of hajj population in the successive years. Second, during this selected period, most of our AMI patients were pilgrims who had special ritual, religious emotions, and soul as most of them were doing their hajj for the first time having beliefs that longer hospital stay might reduce the opportunity to complete the hajj for which they were coming and persistently asking all the time for discharge. We believe that appropriate early post AMI discharge might grant their wishes provided it is totally safe. Third, during this short 2\u2009weeks of hajj season additional two millions of population increase within Makkah city from pilgrimage and this requires a huge health service demand. Many facilities provided by the Ministry of Health and Hajj Committee during hajj seasons to provide a tremendous 24\u2009h non-stop cardiac services included increasing manpower, raising number of working cath labs, improving working network, expanding all available services, and hence all that motivate the huge work and discharge of stable cases. We started implementation of early discharge program on hajj season 2018 and continued on 2019 to enlarge our sample size, which might help to gather more data and generalize our conclusion.Our results concluded that those early discharged patients had higher percentage of pilgrims who were in high need for early discharge to compete their hajj pillars with their groups and return back to the their home countries safely. They also showed to have low-risk AMI features including less prevalence of cardiovascular risk factors and comorbidities, which all might predict safe early discharge post revascularization. Early revascularization with PPCI with appropriate target for DBT was recorded higher among those early discharged patients and this reflects higher quality of service provided by our center to AMI patients and could help in the process of early discharging them from the hospital. Clinical features and short-term outcome of AMI patients post event are crucial once decided the discharge process and these were followed carefully during our program implementation . Reassuringly, most of our early discharged patients had favorable coronary artery disease anatomy and this encouraged their early discharge process.Follow-up data results were impressive as majority of our early discharged patients were totally asymptomatic (95%). Few percentages of those patients had non-serious symptoms and did not require any major intervention and this might reflect the early success of implementation of such program in our facility, which is considered the corner stone in the region.Finally, our current experience reflects many advantages: great compensation of the huge required hospitalization burden; provision of the best, safe, and maximum service for cardiac patients during over crisis periods; lower hospital cost; and improvement of patient\u2019s satisfaction.Our study is limited to a single center and relatively small population number (short period selected only two hajj seasons) corresponds to the conclusions of mentioned studies. There are many factors explaining limitation of our follow-up data (as 40% of our early discharged patients lost their follow-up): language barrier, wrong written contact number in our records, non-attending calls, and higher percentage of those patients were pilgrims who returned back to their countries immediately after hajj without any follow-up here. We tried to support our results with some previous randomized studies with such recommended strategies and shorter length of hospital stay.Suggested plan to establish proper educational program with help of the health promotion department supported with different language materials, which will be provided to those patients during their hospitalization regarding to their disease process, medication compliance and proper short-/long-term follow-upProper recording of correct contact numbers of the patients organized by our admission office and bed management departmentsMotivation of the primary and secondary hospitals in the regions to conduct similar programs and possible organization of better follow-up protocolsWe hope to reduce these limitations in future seasons by the following suggestions:Our results provide preliminary data to support safety of early discharge in a carefully selected group of AMI patients while providing them dedicated telephone support and follow-up. Early but safe discharge may have huge impact on increasing patient\u2019s satisfaction, bed availability and reducing hospital costs. Furthermore, a larger multi-center study in the region has been encouraged to generalize our conclusion."} +{"text": "The present study analyzes the drug-target-disease network and may prove to be a useful tool in gene-phenotype connectivity for genistein in HBV-related liver cancer. Our data also pave the way for further research on Grb2 during the development of chronic HBV infection in liver cancer.Genistein is a type of isoflavone, which has been widely described as an antitumor agent in many cancers. The present study aimed to provide information on the mechanisms of genistein's activity and thus enable a wider range of targeted therapies in hepatitis B virus (HBV)-related liver cancer. We searched the DrugBank database for direct targets of genistein, which were then analyzed through the STRING database to predict their secondary protein targets. Thirteen primary protein targets of genistein and 209 secondary protein targets-associated genes were identified. The data were integrated into the network of protein targets-associated genes and visualized with the Cytoscape software. We further carried out GO (Gene Ontology) analysis and KEGG (Kyoto Encyclopedia of Gene and Genome) pathway analysis using DAVID tool. The top 14 KEGG pathways were further assessed, and 19 overlapping genes derived from pathways of hepatitis B and cancer were discovered. The overlapping targets were further mapped in the online tool UALCAN to evaluate the survival rate of hepatocellular carcinoma (HCC) patients. We found that the overexpression of Grb2 (growth factor receptor-binding protein 2) ( Worldwide, chronic infection due to hepatitis B virus (HBV) is recognized as a major reason for hepatocellular carcinoma (HCC), with a huge financial burden to the society database, and generated 209 secondary protein targets-associated genes and constructed their protein\u2013protein interaction (PPI) network with the Cytoscape software. Primary target genes and the genes associated with them were further analyzed using DAVID online tools for KEGG (Kyoto Encyclopedia of Genes and Genomes) biochemical pathways, and finally, the top 14 KEGG pathways were picked out. Nineteen overlapping genes derived from hepatitis B and pathways in cancer on the top 14 KEGG pathways were identified. At last, the expression level and overall survival (OS) of these hub genes were analyzed with UALCAN, which is a tool to facilitate the study of survival associations and gene expression variations across tumors based on exhaustive evaluation of TCGA (The Cancer Genome Atlas) gene expression data enrichment analysis and KEGG pathway enrichment analysis were carried out using an online tool DAVID, which is an online database and analytic tool that provides information about a large list of genes or proteins and their potential functions between normal and tumor samples and assess the effect of clinicopathologic features and level of gene expression on patient survival , prolactin signaling pathway (19 genes), pathways in cancer (37 genes), hepatitis B (23 genes), focal adhesion (26 genes), erbB signaling pathway (18 genes), PI3K/AKT signaling pathway (33 genes), proteoglycans in cancer (25 genes), estrogen signaling pathway (18 genes), colorectal cancer (15 genes), FoxO signaling pathway (20 genes), AMPK signaling pathway (19 genes), mTOR signaling pathway (14 genes), and HIF-1 signaling pathway (17 genes) .

We found that expression of GRB2 (p\u2009<\u20090.0001) followed by AKT1 (p\u2009=\u20090.0015) and PIK3CA (p\u2009=\u20090.0088) was linked to worse OS for liver HCC patients (The expression level and prognostic details of 19 selected genes are accessible online (patients . The UALInvestigations carried out in the past decades have shown that genistein demonstrates synergistic activities combined with chemo-drugs (Spagnuolo et al., A system biochemistry approach integrating multiple web-based tools was applied, and associations of HBV-related HCC and biological molecules with drug targets were evaluated. We obtained 13 primary and 209 secondary target genes/proteins in DrugBank and STRING. Nineteen overlapping genes from 2 of 14 enriched KEGG pathways related to genistein-altered genes were selected. The overexpression of AKT1, PIK3CA, and GRB2 in HCC was linked to decline in OS as per UALCAN. Therefore, we hypothesized that those three genes might be potential targets by genistein during the development of chronic HBV infection into liver cancer.The PI3K/AKT signaling pathway has been found abnormally activated in HCC and affects cell behavior, including proliferation, survival, metabolism, and tumorigenesis (Chen et al., In conclusion, with the increase in number of studies on genistein by traditional experimental techniques, more and more genistein targets will undoubtedly be identified. However, there is ambiguity in determining whether the specific biological effects on genistein can be definitively assigned to the individual or simultaneous modulation of their newly established or identified targets. This analysis enabled the interpretation of the inherent mechanisms of HBV-related cancer and genistein's target identification and would ultimately aid in future studies with rational experimental likelihood for detection and validation of logical hypotheses about the role of genistein in HBV-related liver cancers in the future."} +{"text": "This talk explores the importance of a racially diverse graduate student interacting in an applied care setting with minority older adults in the Southeast relative to assessment of cognitive status and in the context of cultural mistrust and misdiagnosis. ~250 older adults (16% AA) in an applied care setting were administered a cognitive screener as part of a larger research battery.

Seventeen participants (34%) occasionally used a test for prediction of the ovarian reserve before surgery, and the most commonly used test was anti-mullerian hormone assay . Laparoscopy was the preferred method for staging tubal disease .Thirty-seven (76%) participants always performed salpingectomy or tubal occlusion before the first IVF attempt. Thirty (60%) of the gynaecological surgeons considered the outcome with tubal surgery and IVF to be similar in mild tubal disease, whereas for severe disease, 31/50 (62%) felt that surgery had worse outcome. Among other factors to be considered in choosing a strategy for treating infertility, 20/50 (40%) of respondents listed the stage of disease. The findings of this survey suggest that first-line treatment for women younger than 35 years old with minor tubal pathology, is tubal surgery. IVF appears to be offered if there are other infertility factors, if the patient is >38 years old and if moderate to severe tubal disease is present. Tubal disease is responsible for 30-40% of cases of female infertility. Pathology of the fallopian tubes may vary from peritubal adhesions and distorted tubal anatomy or damaged fimbriae to hydrosalpinx or tubal blockage . Pelvic st to March 31st , 2019, ESGE members were invited by the ESGE Central Office to complete a 22-item online questionnaire, accessible through the ESGE website. For some questions, more than one answer was acceptable. The invited gynaecological surgeons were not specifically infertility specialists, but they had experience in laparoscopic treatment of tubal-factor infertility. The participants received three reminders during this period. Fifty 50 gynaecological surgeons participated in the survey.A questionnaire survey was conducted to assess the approaches of members of the European Society for Gynaecological Endoscopy (ESGE). From March 1Forty-eight (96%) of the participants were specialists and two (4%) were trainees. Sixty per cent of the participants were aged 35 to 54 years; 25(50%) were experts who performed more than 90 laparoscopic procedures per year; and 19 (38%) had over 16 years of practice in endoscopic operations. Eighteen (36%) of the participants performed more than 30 laparoscopic tubal operations per year and 22 (44%) performed 10 to 30 per year. Seventeen of the participants (34%) worked in a university teaching hospital and 25 (50%) worked in a national health service hospital.According to 43 (86%) of the surveyed gynaecological surgeons, the best method for staging tubal disease was laparoscopy. Salpingectomy was the operation preferred by 30 (60%) participants, salpingoneostomy by nine (18%), tubal anastomosis by six (12%) and tubal occlusion by two (4%). Twenty-nine (58%) of the participants preferred bipolar energy for electrocoagulation during surgical treatment for tubal disease. When there is an incidental finding of hydrosalpinx 21(42%) of the gynaecological surgeons reported treatment in all cases; 18 (36%) reported treatment depending on the case; six (12%) reported no treatment; and 4 (8%) reported treatment only in case of bilateral disease. When hydrosalpinx was an incidental finding, 43 respondents (86%) preferred to inform the patient first and perform second-look surgical treatment only when there is indication, such as pain or infertility.In treatment of asymptomatic hydrosalpinx 23 (46%) gynaecological surgeons reported using no routine antibiotic treatment, 18 (36%) reported using occasional antibiotic treatment; and five (10%) reported using antibiotic treatment in all cases. When antibiotics were used for this condition, 20(40%) of the gynaecological surgeons seemed to prefer a combination of doxycycline, cephalosporin and penicillin, whilst 25 (50%) seemed to prefer doxycycline or cephalosporin only.Twenty-two (44%) participants reported using a test for predicting ovarian reserve in all cases before tubal surgery for infertility, and 40 (80%) felt the most precise and reliable test for predicting ovarian reserve is the serum anti-Mullerian hormone assay. Twenty-four (48%) reported salpingectomy as the best method for surgical treatment of hydrosalpinx in case of infertility, while 17 (34%) prefer laparoscopic tubal occlusion, six (12%)prefer salpingostomy, and three (6%) prefer hysteroscopic tubal occlusion, with permanent micro inserts to cause fibrosis and irreversible tubal occlusion, which develop within three months of insertion.Thirty-seven (76%) participants always performed surgical treatment of hydrosalpinx before the first IVF attempt, and 40 (80%) supported salpingectomy as being the best operative method regarding the outcome of a following IVF attempt. For women with mild tubal disease, good ovarian reserve and no other infertility factors, the prognosis of tubal surgery versus IVF is similar according to 30(60%) respondents. For women with moderate tubal disease 19(38%) participants felt that surgery and IVF had similar outcomes, and 17 (34%) felt that surgery had worse outcomes. In the treatment of severe tubal disease, 31 (62%) gynaecological surgeons stated that tubal surgery has worse outcomes than IVF. Twenty-two (44%) of participants reported that the combination of both methods imposes higher cost. Finally, according to 20 (40%) of the surveyed gynaecological surgeons, the stage of tubal disease is the first factor to take into account when considering strategies for treating infertility, whereas 30 (60%) felt that age and other infertility factors are most important.The results of this survey of 50 members of the ESGE on surgical treatment of tubal-factor infertility are comparable to the published literature on this subject. Thirty-eight (76%) participants favoured laparoscopy as the ideal method for the evaluation of tubal patency and the diagnosis of tubal disease, which is in line with reported practice . Almost Based on the survey responses, first-line treatment for women less than 35 years old with minor tubal pathology seems to be tubal surgery. IVF appears to be offered when there are other infertility factors, if the patient is >38 years old, and when moderate- to-severe tubal disease is present. According to the surveyed laparoscopic surgeons, tubal surgery and assisted reproductive technology in most of the cases are not competitive techniques, but usually tubal surgery is a prerequisite for the success of the IVF. Optimizing pregnancy rates and reducing the risks associated with IVF or surgical treatment should always be the main goal. The outcome of our survey is especially meaningful because of the high level of expertise in laparoscopic surgery and the high level of expertise in the laparoscopic treatment of hydrosalpinx among the participating gynaecological surgeons. On the other hand, the insufficient number of participants is a drawback, which points out the need for a future survey, better designed and with more gynaecologists with experience in laparoscopic treatment of tubal-factor infertility. Such a survey would minimize bias and produce clear answers and recommendations."} +{"text": "Family caregivers provide the majority of support for older adults and people with disabilities in the U.S. The onset of the COVID-19 pandemic forced radical changes in duties and relationships between family caregivers and care recipients. These changes can be attributed to fears of virus transmission as well as federal, state and local government mitigation strategies resulting in social distancing and quarantining limiting caregiving interactions. This qualitative investigation conducted 55 Zoom interviews over summer 2020 with family caregivers to explore their changing roles and duties during the pandemic. Researchers utilized a semi-structured interview guide to explore caregiver experiences with COVID-19. The average age of the caregiver participants was 59 and the average age of the care recipients for whom they provided care was 74. All participants provided unpaid care for family members. Interviews were conducted in English (n=40), Spanish (n=5), Somali (n=5) and Korean (n=5). Care recipients resided in a facility (70%) with the caregiver (20%), and in a separate independent setting (10%). Data from each interview were coded into themes by two researchers. Themes that emerged from the analyses included concerns about care recipient mental and physical health deterioration, lack of communication from formal providers, change in relationships with other family members, and future concerns.

In this study, researchers interviewed 17 Chinese homebound adults aged 45 and older who have received HBMC, and collected detailed information regarding their experiences and attitudes toward HBMC. Participants were recruited from healthcare institutions in Shanghai, Jinan, and Zhangqiu of China. The evaluation of patients\u2019 experiences with HBMC yielded both positive and negative aspects. Positive experiences included 1) the delivery method was convenient for homebound patients; 2) health problems could be detected timely because doctors visited patients regularly; 3) home care providers had better bedside manners and professional skills than hospital-based providers; 4) the medical insurance covered the cost of home care services. Negative experiences related to the supply and quality of care, including 1) the scope of current HBMC services was too limited to meet the needs of homebound patients; 2) the visit time was too short; 3) healthcare providers\u2019 professional skills varied greatly. Findings from this study suggest that the HBMC model benefited Chinese older adults, primarily homebound adults, in terms of convenience and affordability. There are opportunities to expand the scope of home care services and improve the quality of care. Policymakers may consider providing more resources and incentives to enhance HBMC in China.

Growth models with distal outcome were used to examine whether different trajectories of functional abilities (activities of daily living (ADL); and instrumental activities of daily living (IADL)) between 2002/03 and 2010/11, were associated with dementia incidence four years later (2014/15). Participants with an increasing number of functional impairments (Class III), were more likely to be classified with subsequent dementia compared with those with no impairments (Class I). An increased risk was also observed for individuals with raised levels of impairments (Class II). We found IADLs more sensitive than ADLs, and this may imply a more comprehensive ascertainment during the prodromal stage of dementia."} +{"text": "In 2020, the Center of Innovation for Veteran Centered and Value Driven Care (COIN) continued its monitoring and evaluation of the Veterans Administration (VA) Medical Foster Home (MFH) programs expansion into rural areas. Veterans in MFHs are provided 24/7 care by VA trained and supervised community caregivers and primary care by VA Home Based Primary Care (HBPC) teams. One year after the three-year (2017-2019) expansion funds stopped, COIN continued monitoring remaining programs. Objectives were to understand factors critical for program expansion and sustainability and the impact of COVID-19. Phone interviews were conducted with sixteen coordinators from seventeen programs. A thematic analysis approach was used to address the evaluation objectives using transcript data. Findings showed factors important to program sustainability were: 1) Program fit (finding caregivers in the community); and 2) Local VA facility support . COVID prompted losing some caregivers and prevented others from joining. Program staffing was not impacted as many program activities ceased. Recreational therapists (RTs) were significant to maintaining Veterans well-being and reducing social isolation through virtual activities. COVID required coordinators transition their supervision of MFHs to new virtual environments and HBPC to increase telehealth to new levels. Local leadership became important to monitoring local conditions and providing support to programs. The evaluation: 1) Found factors important to program sustainability were also critical to keeping programs operational during the pandemic; and 2) Stimulated future research on the suitability of MFH programs to meet challenges to resurgences of COVID or other national emergencies."} +{"text": "The literature on the contribution of elastic fibre deposition to alcohol-related liver disease (ARLD) is limited. We studied: (1) 180 liver biopsies from ARLD patients; (2) 20 ARLD explant livers; (3) 213 liver biopsies with non-ARLD injury. Elastic fibres were assessed in terms of their distribution around hepatocytes [pericellular elastosis (PCE)] and within bridging fibrous septa and scored using a semiquantitative system. We also investigated the composition of the elastic fibres in 20 cases. PCE was associated with steatohepatitis in ARLD patients and with ARLD when compared to non-ARLD cases (p\u2009<\u20090.001). Oxytalan fibres were identified in PCE in ARLD biopsies and broken dense perisinusoidal mature elastic fibres in explanted livers. Septal elastosis increased from intermediate to advanced fibrosis stage. Early septal elastosis contained oxytalan fibres, whereas septal elastosis at more advanced stages contained mainly mature elastic fibres. PCE is a typical feature of steatohepatitis in ARLD and includes oxytalan fibres. Septal elastosis is a gradual process with a transition from oxytalan to mature elastic fibres usually present in explanted livers. There may be different dynamics in the assembly and reabsorption of pericellular and septal elastic fibres, and a potential role for stratification of patients with advanced stage ARLD. The spectrum of liver injury in alcohol-related liver disease (ARLD) ranges from simple steatosis to steatohepatitis and from minimal or no fibrosis to cirrhosis2. Elastic fibres are a component of the extracellular matrix (ECM) along with collagen, glycoproteins, glycosaminoglycans and proteoglycans3. The elastic fibres are composed of a core of elastin made of tropoelastin monomers encoded by ELN and a microfibrillar mantle composed of fibrillins, glycoproteins which in humans are present in three isoforms4. The relative proportion of tropoelastin and microfibrils divide elastic fibres into three main types: oxytalan, composed of microfibrils only with no elastin core; and elaunin and mature elastic fibres, both characterized by a central cross-linked core of elastin and a surrounding microfibrillar component. Elaunin fibres have a lower amount of elastin compared to mature elastic fibres5. Oxytalan fibres can be differentiated from both elaunin and mature elastic fibres by removing the oxidation step of histochemical elastic fibre staining methods such as the orcein stain or analogues9. Oxytalan fibres do not react with this modified protocol, whereas both elaunin and mature elastic fibres remain positive. Elastogenesis begins in the late stages of development and early after birth10 and is particularly active in those tissues in which elastic properties are essential for their function such as the aortic wall and lung parenchyma4. Elastogenesis is attenuated in normal adult tissues but reactivates in a wide spectrum of disease processes10 including wound healing12. Elastin has long been known to accumulate in fibrotic livers13. Little is known however about its role in the progression of ARLD and the literature on the contribution of elastic fibre deposition in ARLD injury is limited14. Porto et al.14 showed that in the early stage of alcoholic fibrosis there is deposition of oxytalan fibres in the space of Disse in the perivenular region. The internodular bridging fibrous septa of more advanced stages contained oxytalan and elaunin fibres. Our aim was to evaluate retrospectively a large series of liver biopsies from patients with ARLD focusing on the pattern, distribution and composition of elastic fibres.Worldwide alcohol-related mortality in 2016 was high at 38.8 per 100,000 people and half of cirrhosis related deaths were due, at least in part, to alcohol useOut of our initial cohort of 303 biopsies 180 fulfilled our selection criteria and were selected for our study.Seventy-three biopsies (40.6%) showed steatosis only (mild in 36 (49.3%), moderate in 28 (38.4%) and severe in 9 12.3%). Ninety-seven biopsies (53.9%) showed steatohepatitis. Ten (5.6%) biopsies were classified as NOS of liver biopsies at the different disease stage were as follows: 0 (no fibrosis)\u2009=\u20094 (2.2%); 1 (early)\u2009=\u200984 (46.7%); 2 (intermediate)\u2009=\u200934 (18.9%); 3 (advanced stage cirrhotic transformation)\u2009=\u200913 (7.2%); 4 (advanced stage cirrhotic)\u2009=\u200945 (25%).For reference, examples of none and focal perihepatocytic elastic fibres, and PCE are demonstrated in Fig.\u00a0The correlation between pericellular elastic fibres and overall disease pattern is detailed in Supplementary Table PCE was identified in 58 32.2%) of the 180 cases studied. PCE was present in 7 (9.6%) of the 73 biopsies with steatosis, 47 (48.5%) of the 97 biopsies with steatohepatitis, and 4 (40%) of the 10 biopsies classified as NOS. When biopsies were divided into two groups according to presence or absence of steatohepatitis, PCE was significantly associated with steatohepatitis with end stage ARLD. All patients had been abstinent at the time of transplantation for at least 6\u00a0months.Most cases showed a combination of grades 2, 3 and 4 of septal elastic fibres. Grade 0 was not observed in any of these 20 cases and grade 1 was present in three cases only. PCE was not identified in most cirrhotic nodules in 18 cases. It was present very focally in occasional cirrhotic nodules after extensive examination at high magnification in 4 cases, and was easily identified at low magnification in a few (7 cases) or several (7 cases) cirrhotic nodules. The pericellular elastic fibres were often in the form of broken dense strands or in a more perisinusoidal distribution. Examples are shown in Supplementary Figure In two other cases PCE was more prominent affecting approximately half of the cirrhotic nodules in the sample examined. There was no evidence of active steatohepatitis.We next correlated our findings with the immunohistochemistry for elastin and the repeat Victoria blue stain with and without the oxidation step to explore the proportion of oxytalan, elaunin and mature elastic fibres. , in all ten biopsies showing grade 1 or grade 2 septal elastosis with the conventional Victoria blue an appreciable reduction in elastic fibre stain with the modified Victoria blue method suggested the presence of a significant proportion of oxytalan.Grade 3 or 4 septal elastosis, consisted of elastin positive septa without reduction in stain with the modified Victoria blue stain indicating that the septa were composed mostly of mature elastic fibres.PCE appears to be composed of a significant proportion of oxytalan in most of the biopsy specimens and of mature elastin in the explanted livers . Further studies are needed to better understand whether the elastification process can be used to stratify patients with advanced stage ARLD and correlate with clinical outcome.Our study was based on four cohorts of specimens; (i) a series of 303 core needle biopsy specimens from patients with known ARLD clinically; (ii) a series of 20 livers removed at transplantation for ARLD; (iii) a control group of 213 core needle biopsy specimens with a variety of liver conditions other than ARLD characterized after clinico-pathological correlation; (iv) a selection of representative cases from cohorts (i) and (ii) to investigate in more details the elastic fibres morphology and composition in terms of oxytalan, elaunin and elastin content.16: steatosis, steatohepatitis, and not otherwise specified (NOS).Our review of the first cohort of biopsies included the assessment of the overall pattern of liver injury, fibrosis stage, and pattern of elastic fibre deposition. The biopsies were divided into the following categoriesFibrosis staging was carried out using a semiquantitative scoring system (0 no fibrosis identified); 1 or early; 2 or intermediate (bridging fibrosis); 3 or advanced stage with features of cirrhotic transformation; and 4 or advanced stage cirrhotic.We assessed the presence of elastic fibres in a pericellular/perivenular distribution and within fibrous septa.Pericellular elastic fibres were classified as absent, focal and after extensive search), or pericellular elastosis (PCE) (perihepatocytic elastic strands obvious at 10\u2009\u00d7 or 20\u2009\u00d7 magnification).We classified septal elastosis into the following grades: grade 0: bridging fibrous septa with no elastic fibres; grade 1: bridging fibrous septa with delicate fibres visible only at high magnification; grade 2: elastic fibres visible at low magnification and clearly distinguishable from the residual portal or liver capsule elastic fibres, grade 3: strong elastic bundles well visible at low magnification and of similar density, blending with or indistinguishable from the to the residual portal normal or liver capsule elastic fibres; and grade 4: slender, regressive type dense elastic bundles visible at low magnification. Pericellular and septal elastosis were further investigated, in terms of their composition on a subseries of 20 cases using 6 serial sections. The sections were stained in the following sequential order with (i) anti-Elastin [BA4] antibody IHC (ab9519), (ii) Victoria blue with no oxidation step (demonstrating only mature elastin fibres and Elaunin), (iii) Victoria blue with oxidation and decolourisation step , (iv) (spare unstained back-up section), (v) Picrosirius red and (vi) Haematoxylin and Eosin. Reduction in stain between the Victoria blue with and without oxidation step was assessed as follows: minimal and focal ; partial ; marked . Septal elastin immunohistochemical stain was regarded as diffuse when present in most or all septa and patchy when approximately half of the septa were negative. Pericellular elastin stain was considered as diffuse (most hepatic plates), patchy , focal (identified at high magnification after extensive search) or absent.Details on the biopsy selection, histological categories, fibrosis scoring system staining protocols, statistical analysis and elastic fibres assessment are provided as supporting information. All methods were carried out in accordance with relevant guidelines and regulations, experimental protocols were approved by the Royal Free Hospital Ethics Committee (07/Q0501/50) and informed consent was obtained as appropriate.Supplementary Information."} +{"text": "Loneliness and social isolation present emerging public health challenges for aging populations.

We used longitudinal, repeated measures data to isolate effects of loneliness and social isolation from effects of socioeconomic circumstances and psychological vulnerabilities, rule out reverse-causation, and test dose-response in associations with morbidity, disability, and mortality. We also explored the biological basis of relationships by testing associations with biological aging. We analyzed data from more than 12,000 adults aged 50-95 in the US Health and Retirement Study (HRS) who reported on symptoms of loneliness and social isolation at 2-3 time points during 2006-2014. We measured loneliness using the 3-item Revised UCLA Loneliness Scale and social isolation using a 6-item scale. We tested associations with chronic disease, disability, and biological aging in 2016 and with mortality through 2018. We found (1) associations of loneliness and social isolation with adverse aging outcomes are not fully explained by socioeconomic circumstances and psychological vulnerabilities; (2) the direction of relationships with disability indicates temporal precedence of loneliness and social isolation; (3) there is a dose-response in associations with loneliness; and (4) there is evidence of a biological mechanism explaining associations with loneliness and social isolation.

As an alternative to synthetic chemical treatments, plasma technology could be one of the emerging technologies to enhance seed germination and seedling vigor by managing environmental stressors. Recent studies have shown its beneficial effects in various stress conditions, suggesting that plasma treatment can be used for early crop stress management. This paper reviewed the effects of different types of plasma treatments on plant responses in terms of the seed surface environment (seed scarification and pathogen inactivation) and physiological processes (an enhanced antioxidant system and activated defense response) during the early growth stages of plants. As a result, plasma treatment can enhance seed invigoration and seedling establishment by alleviating the adverse effects of environmental stressors such as drought, salinity, and pathogen infection. More information on plasma applications and their mechanisms against a broad range of stressors is required to establish a better plasma technology for early crop stress management. Rapid seed invigoration and seedling establishment during the early growth stages of crops are necessary to prevent crop yield loss due to unfavorable environments. Seed germination and early seedling growth are the most sensitive growth stages for a crop to a wide range of environmental stressors . Once thPlasma technology has been widely designated as an advanced oxidation process . It has However, no review has yet summarized plasma applications and their protective mechanisms against a broad range of stressors. The potential applications of plasma technology for early crop stress management are largely unknown. This review evaluated the effects of the different types of plasma treatments on plant responses in terms of the seed surface environment (seed scarification and pathogen inactivation) and physiological processes (an enhanced antioxidant system and activated defense response) during the early growth stages of plants. Recent information on plasma applications and their mechanisms against a broad range of stressors was reviewed from these two perspectives. Thus, this review proposes that plasma technology has potential uses for seed invigoration and seedling establishment under stressful conditions.The seed coat regulates seed germination through its thickness and permeability. Therefore, seeds with thick coats are incapable of water uptake rapidly unless it is scarified . In part6H5NH2) or cyclohexane (C6H12). However, RF discharge delayed the germination time of maize, radish, and some legumes such as soybeans, peas, and common beans when generated from carbon tetrafluoride (CF4) or octadecafluorodecalin (ODFD) otherwise known as perfluorodecalin (2H4) .Dielectric barrier discharge (DBD) has been proven to be effective for seed germination and seedling vigor when generated under optimal conditions. DBD in air induced faster germination, leading to a better germination rate and early seedling growth of wheat, barley, and peas under laboratory conditions . A DBD wOther discharge plasmas, including corona, arc, glow, and microwave discharges, also have shown stimulating effects on seed invigoration of some crops although their maximum values differ depending on the treatment conditions of the plasma sources .These results suggest that plasma treatment can enhance the water absorption of seeds, thus leading to a better invigoration of crops. The beneficial effect of plasma treatment on seed invigoration is mainly associated with its power (W) and exposure time (min) , plasma treatments with DBD and arc discharge effectively inactivated its growth and thus reduced the fungal infection of rice by a maximum value of 51% under environmentally controlled conditions radical into hydrogen peroxide (H2O2) and an ordinary molecular oxygen (O2). Finally, CAT in peroxisomes and PODs in the cytosol detoxify the hydrogen peroxide (H2O2) by catalyzing its reduction to water (H2O). Together with these enzymes, non-enzymatic antioxidants can provide cells with highly efficient machinery to detoxify the molecular species of active oxygen. After plasma treatment, the enhancement of these antioxidant systems has recently been reported in a few crops , catalase (CAT), and peroxidase (POD), in plant cells . The antCellular antioxidant systems are effectively enhanced by plasma treatments with a low power (W) and short exposure (min) see . SimilarDielectric barrier discharge has shown positive effects on the contents of the total phenolic compounds under laboratory conditions, although its effects depend on the types of feed gas. These results indicate that plasma treatments generated with a low power and short exposure time can enhance cellular antioxidant systems through H2O2-mediated signaling activating defense-related responses and physiological processes in seeds under stressful conditions such as drought, salinity, and pathogen infection (1) reduce infection with pathogenic microorganisms in germinating seeds or growing plants (2) regulate ROS homeostasis through the antioxidant machinery of plants (3) activate other defense-related responses in plant cells and the seed surface, seed-borne pathogens, and cellular homeostasis, respectively. Although the plasma-induced effects are still poorly understood, their potential mechanisms for crop stress tolerance can be suggested based on the review of the literature on plasma-induced plant responses (Section 2). The ROS, RNS, and UV of plasma can change the physical and chemical properties of the seed surface before exposure to environmental stressors, thus enabling seeds to be more hydrophilic and permeable to water. Scanning electron microscopy studies have shown partial degradation of cellulose and formation of cracks on the surface of plasma-treated seeds . Additiog plants , 2) reguf plants , and 3) nt cells . Many stnt cells . AltogetSeed invigoration and seedling establishment under stressful conditions are highly variable depending on numerous factors, including biological and environmental factors . There is little or no information for establishing crop stress management practices using plasma technology. To our knowledge, there are only a few studies under laboratory conditions on crop tolerance to disease , droughtPlasma applications have been widely used for seed scarification, pathogen inactivation, and antioxidant system activation with proven beneficial effects on seed invigoration and seedling establishment under laboratory and greenhouse conditions. Moreover, the optimal plasma exposure can enhance crop tolerance before stress events by modulating the seed surface environment and physiological processes in seeds. This promising technology is potentially valuable for alleviating the adverse effects of environmental stressors on seed germination and seedling growth in crop production. However, information on plasma effects under stressful conditions is limited to a few crops under laboratory conditions. Further studies are necessary to fully understand the effectiveness of plasma applications to a broad range of stressors under field and greenhouse conditions. This review suggests that the power (W) and exposure time (min) are vital operating parameters of the plasma treatment that affect the phenomenon of the plasma. More experimental evidence is needed to adopt the use of the power (W) and the exposure time (min) as standardized values for the plasma treatment of various crops \u201d through the National Fusion Research Institute of Korea (NFRI) funded by government funds.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "The Chinese Center of Disease Control and Prevention (CDC) executed an intensive investigation program.

Materials and methods: Questionnaire mailed in autumn 2015 to members of human pharmacology societies in Europe for anonymous responses via the online tool SurveyMonkey. Results: 53 of the ~ 700 addressees participated in the survey. 23 female trial participants and 11 female partners of male trial participants were exposed to investigational medicinal products during unintended pregnancies in a clinical trial. Most survey respondents confirmed adequate contraceptive methods by in/exclusion criteria and the use of pregnancy tests in female trial participants at screening and before the first dose. The last menstrual period was documented less frequently . A considerable proportion of respondents denied the routine use of compliance checks about the appropriate use of contraceptive methods, had no procedures in place if contraceptive methods failed, and did not train physicians in instructing trial participants about the appropriate use of contraceptive methods. Conclusion: The methods to avoid unintended pregnancies during participation in a clinical trial need improvement and should include (i) pregnancy tests, (ii) documentation of last menstrual period before the first dose, (iii) compliance checks of the appropriate use of contraceptive methods, and (iv) training of trial physicians. Procedures should be in place for what to do if contraceptive methods fail. What is known about this subject Pregnancies in early clinical drug development must be avoided Appropriate methods to avoid unintended pregnancies are to be defined in the clinical trial protocol Guidance is provided in the ICH M3(R2) and the respective European Clinical Trial Facilitation Group recommendations (CTFG 2014) What this study adds This AGAH survey revealed that unintended pregnancies occur in early clinical drug development Regulatory recommendations are not fully implemented The methods to avoid unintended pregnancies during participation in a clinical trial need improvement A series of workshops related to early-phase clinical development has been hosted by the scientific society \u201cAssociation for Applied Human Pharmacology\u201d (AGAH e.V.) in Germany since 2012. In 2015, members from the pharmaceutical industry, contract research organizations, academia, ethics committees, and the German competent authority discussed unintended exposure to an investigational medicinal product (IMP) during pregnancy in clinical trials and its prevention [In early drug development, data on reproduction toxicity are in general not yet available. According to the ICH M3R2) Guidance [ Guidance\u201cMen can be included in Phase I and II trials before the conduct of the male fertility study since an evaluation of the male reproductive organs is performed in the repeated-dose toxicity studies\u201d \u201cFor women of childbearing potential (WOCBP) there is a high level of concern for the unintentional exposure of an embryo or foetus before information is available concerning the potential benefits versus potential risks\u201d If reproduction toxicity studies are not available, and WOCBP are planned to be included in a clinical trial, the guideline recommends limiting the risk by taking precautions to prevent pregnancy by (i) pregnancy testing , (ii) use of highly effective methods of birth control, and (iii) trial entry only after a confirmed menstrual period. To enable trial participation of WOCBP, the ICH M3R2) Guidance [ GuidanceInformed consent should be based on known risks to the embryo/fetus related to reproduction toxicity. A general assessment of potential toxicity of pharmaceuticals with related structures or pharmacological effects should be provided If no relevant reproductive information is available, the potential for unidentified risks to the embryo or fetus should be communicated as well Subjects should be instructed to use adequate contraceptive measures during the period of drug exposure which could exceed the length of the trial Pregnancy tests are required during the trial to ensure compliance with the contraceptive measures planned in the trial protocol In Europe, the Clinical Trials Facilitation Group (CTFG) has issued further recommendations related to contraception and pregnancy testing in clinical trials . They arA survey was conducted (i) to collect information on unintended pregnancies during clinical trials in early drug development and (ii) to learn from current experience whether applied precautionary measures are in line with current guidances , 3 and aDefinitions used are: Drug exposure via parent (DEVP) Unintended drug exposure during pregnancy in a clinical trial The survey addressed specialists working in early-phase drug development in Germany, Belgium, France, and the United Kingdom. The questionnaire compriseThe questions covered the following topics (see questions (Q) provided in Characteristics of survey participants Number and cause of unintended pregnancies in female participants and female partners of male trial participants in clinical trials combined in one protocol (Q3\u00a0\u2013\u00a0Q8) Age of women becoming accidentally pregnant in a clinical trial (Q9) Preventive measures (Q10\u00a0\u2013\u00a0Q13) It cannot be excluded that different participants belonging to the same organization referred to the same trial protocol(s). In consequence, a qualitative rather than quantitative interpretation of results is indicated. Not all survey participants answered all questions. For the respective questions, the total number of responses is given . A total of 53 of ~ 700 addressees answered the questionnaire. The majority came from contract research organizations (19), the pharmaceutical industry (15), but also from academia (8), independent consultants (8), biotechnology (2), or regulatory authority (1). Participants were from Germany (47), The Netherlands (3), Belgium (1), Luxembourg (1), and South Africa (1). 15 survey participants reported that 23 female clinical trial participants were unintentionally exposed to IMP during pregnancy in a clinical trial they sponsored or conducted during the past 10 years. 33 survey participants denied the occurrence of such pregnancies. A total of 10 survey participants reported that 11 female partners of male clinical trial participants were unintentionally exposed to IMP during pregnancy in a clinical trial they sponsored or conducted during the past 10 years. 36 survey participants denied the occurrence of such pregnancies. These included (i) non-compliance with trial-specific contraceptive methods (9), (ii) \u00a0failure of contraceptive methods (3), and (iii)\u00a0failure of the pregnancy test to detect pregnancy at screening or before first dose (1). The main outcome of this AGAH survey demonstrates that the occurrence of unintended pregnancies is a relevant issue in early drug development despite considerable effort to avoid them. Taking into account that 53 out of ~ 700 addressees responded, it may be assumed that the unintended exposure to IMPs in early pregnancy is higher than reported here. The number of participants is not a representative sample of all parties conducting clinical trials in Europe. Participants from the same organization may have referred to the same trials. To provide (i) data with respect to a topic with considerable lack of information, (ii) data on failure of/or compliance with contraceptive methods, (iii) data on training of physicians in instructing trial participants how to use the contraceptive methods as specified in the clinical trial protocol. Despite the advice provided in the ICH M3R2) guidance guidance, 5, 6, 7If contraceptive methods fail in a clinical trial, the following procedures are useful in identifying the risk of having become or becoming pregnant and to estimate the usefulness of emergency contraception: Identification of exact kind and time point of contraceptive failure Cycle history Urine pregnancy test If possible, transvaginal ultrasound for determination of ovarian activity Blood sampling for determination of beta-human choriogonadotropin (\u03b2-HCG), estradiol, luteinizing hormone (LH), and progesterone There was agreement among participants of the workshop that good practices to avoid unintended pregnancies in early drug development comprise: Implementation of adequate contraceptive methods in the clinical trial protocol st dose, at appropriate time points thereafter, and upon completion of the clinical trial Pregnancy tests in female trial participants depending on the kinetics of the tested compound. At least screening before 1Written subject information concerning the adequate contraceptive methods to be used during the trial and the necessity avoiding DEVP as well as measures to be taken in case of possibly failed contraception before or during the trial Training of trial physicians on how to instruct trial participants about the appropriate use of adequate contraceptive methods as well as measures to be taken in case of possibly failed contraception Routine compliance checks whether enrolled subjects are appropriately using the contraceptive methods as per protocol Standard procedures in place regarding what to do if contraceptive methods failed Decision on further measures to avoid unnecessary elective pregnancy terminations Compliance with measures indicated by the CTFG publication Female clinical trial participants and female partners of male clinical trial participants must not become pregnant during early drug development; however, this AGAH survey shows that pregnancies did occur. According to the discussions during the workshop, the methods to mitigate the risk of unintended pregnancies need further improvement and should include (i) written information of the trial participants regarding contraceptive measures and the necessity of avoiding drug exposure via parent, (ii) repeated pregnancy tests, (iii) documentation of last menstrual period before the first dose, (iv) compliance checks of the appropriate use of contraceptive methods, (v) training of trial physicians. Procedures should be in place for what to do if contraceptive measures fail. Lessons learned from unintended pregnancies should result in appropriate modification of hitherto implemented procedures. This will mitigate the risk of DEVP in early-phase clinical trials. We thank Sam Welgemoed for her technical support . We thank all participants of the survey for their contributions. Survey: None.

Supplemental material"} +{"text": "Following these two introductory chapters, the monograph can then be divided into four main sections: (i) the technical overview of currently available commercial SGRT Systems (chapters 3\u20135), (ii) the commissioning of the systems described in part (i) (chapters 6\u20138), (iii) the clinical application of SGRT (chapters 9\u201319), and (iv) miscellaneous topics in surface image guidance (chapters 20\u201326). While the corresponding chapters in part (i) and (ii) can be read independently of each other, I personally would have found it more helpful if the technical overview of a particular surface image guidance technology would have been followed by the chapter on its commissioning. Having said that, each of the chapters in part (i) and (ii) strikes the right balance between technical detail and brevity, making them very useful both as a reference and an introduction to the technology and how to commission a given technology of surface image guidance. Part (iii) begins with an in depth look at the clinical application of this technology to breast cancer (chapters 9\u201311), while Chapters 12\u201314 consider Stereotactic Radiosurgery and Stereotactic Radiation Therapy in depth, including a very nice chapter on the risk analysis for SGRT\u2010based SRS/SRT. Part (iii) continues with a detailed description of respiratory motion management strategies employing surface image guidance in SBRT (chapter 15), including the use of surface image guidance for SBRT without respiratory gating (chapter 16). Chapters on the use of surface image guidance in the treatment of Head and Neck (chapter 17), extremities (chapter 18), and pediatric patients (chapter 19) conclude Part (iii). Chapters 20\u201326 round out the presentation with three perspectives on the clinical implementation of surface image guidance, one from the point of view of a physicist and two from the that of a radiation therapist (chapters 20\u201322); applications of surface image guidance to proton therapy (chapter 23); integration of surface image guidance into tomographic and bore type gantry systems (chapter 24); use of consumer grade cameras and alternate approaches to surface image guidance (chapter 25); and a final chapter discussing future directions for SGRT (chapter 26).In summary, this monograph presents a very readable account of the technical features of currently commercially available SGRT technologies, considers the commissioning of each in detail, and discusses in detail the clinical implementation and use of these systems for a number of important clinical sites, such as Breast, Stereotactic Body Radiation Therapy, Stereotactic Radiosurgery and Stereotactic Radiation Therapy, and Head and Neck. Regardless of career stage, professionals in either therapeutic medical physics or radiation oncology will find this monograph beneficial.

Diagnostic imaging is irreplaceable in both diagnosing and monitoring patients suffering from systemic sclerosis. In addition to routinely used methods, such as comparative X-ray of the hands or a contrast-enhanced examination of the upper gastrointestinal tract or chest, there is an array of less widespread examinations, with an emphasis on magnetic resonance imaging (MRI) and ultrasonography, not only in the evaluation of the musculoskeletal system. This article will review the various imaging modalities available for SSc imaging and assessment, focusing on their utility as tissue-specific diagnosis and treatment monitoring. Systemic sclerosis belongs to a wide spectrum of connective tissue diseases\u2014a diverse group of disorders characterised by chronic inflammation of connective tissue, usually of autoimmune origin . The mosSSc typically affects women (4:1 predilection), with the median onset at the age of 30\u201350 years. There is a higher morbidity within black patients than in other ethnical groups. A very high prevalence of SSc in Choctaw Native Americans suggests the possibility of a genetic factor in the pathogenesis of this disease. Reports of familial history of SSc or other autoimmune disorders in SSc patients have also shown support for the genetic grounds of SSc. The incidence rate seems stable over several decades in both Europe and the United States ,3,4,5. TThe diagnostic criteria for SSc are still not universal. The classification criteria of the American College of Rheumatology (ACR), presented in 1980 and updated by a collaboration of ACR and European League Against Rheumatism (EULAR) in 2013, are used most commonly. According to those criteria, skin thickening proximal to the metacarpophalangeal joints is sufficient proof of SSc. If it is not present, seven other signs should be evaluated: (1) skin thickening of the fingers (either sclerodactyly or puffy fingers); (2) fingertip lesions ; (3) telangiectasia; (4) abnormal nailfold capillaries; (5) pulmonary arterial hypertension (PAH) and/or interstitial lung disease; (6) Raynaud\u2019s phenomenon; and 7) SSc-related antibodies: anticentromere and/or anti-topoisomerase I (anti-Scl-70) and/or RNA polymerase III , al, al83], The prevalence of ischaemic heart disease related to vasospasm is increased in SSc patients. The vasospasm is often triggered by low temperature, and this symptom is sometimes labeled as the Raynaud phenomenon of the heart. It might be confirmed by visualising subendocardial hypoperfusion areas during an MRI examination .MRI \u2018wall tagging\u2019 and phase contrast techniques are useful to assess fibrosis and diastolic heart failure .Native and post-contrast T1 mapping combined with T2 mapping and LGE (late gadolinium enhancement) discriminate between several myocardial diseases and notably between myocardial fibrosis and edema. The number of studies regarding T1 and T2 mapping is rapidly increasing and the available data show that native T1 mapping detects left ventricular elevated T1 in 50% of patients with SSc while a third of them had normal conventional screening (including standard CMR). This proves that T1 mapping cardiac MRI imaging frequently detects subclinical diffuse myocardial fibrosis in systemic sclerosis patients .In patients without evidence of fibrosis (in LGE), T1 mapping parameters (extracellular volume fraction (ECV), gadolinium partition coefficient (\u03bb), pre-contrast T1, and post-contrast T1) correlated with the modified Rodnan skin score, indicating a correlation between SSc cardiac and skin fibrosis. .Moreover, T1-mapping offers incremental diagnostic value in the identification of patients with high risk of cardiovascular incidents and in addition to independently predict adverse outcomes at follow-up. Thus, CMR may be considered in cases where echocardiographic results are equivocal but the clinical picture warrants a higher index of suspicion, in order to identify high-risk patients early on and to institute prompt changes in the therapeutic management of SSc-related cardiac involvement .MRI allows to recognize one of the more common manifestations of the SSc in the GI tract\u2014lesions of the anus and rectum. Characteristic symptoms include ventral displacement of the anterior rectal wall, decreased thickness of the anal sphincter, and its reduced contrast enhancement caused by its fibrosis . In the A recent survey implies possible applications of MRI ultrafast echo-spin sequences in diagnosing interstitial pulmonary involvement\u2014a correlation between the results of MRI and HRCT was proven .In conclusion, SSc is associated with various radiological findings of specific organ and system manifestations of SSc, which may be apparent in its initial presentation and/or subsequent disease phases. This review may help clinicians and radiologists in the initial diagnosis and monitoring of progression of SSc."} +{"text": "This cohort study examines the association of participation in a summer college academic enrichment program with diversity of students in medical school and intent to practice in underserved areas. As a strategy to increase diversity, many organizations and institutions sponsor premedical summer college academic enrichment programs (SCAEPs) that may address Liaison Committee for Medical Education Standard 3.3, Diversity/Pipeline Programs and Partnerships.2 and Graduation Questionnaire.3 The AAMC Human Subjects Office exempted the study from institutional board review because it did not constitute human participant research and used deidentified data. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline.This cohort study included US medical school matriculants from 2013 to 2015 who graduated through 2019 and voluntarily completed the Association of American Medical Colleges (AAMC) Matriculating Student Questionnaire5, by using program reports to the AAMC and other SCAEP participants (excluding those in SMDEP) by Matriculating Student Questionnaire self-report.2 We examined bivariate associations between SCAEP participation and sex, race/ethnicity, and first-generation college graduate (FGCG) identity and examined factors associated with sustained career intention (Matriculating Student Questionnaire and Graduation Questionnaire self-report) to practice in underserved areas by multilevel logistic regression. P values were 2-sided, and statistical significance was set at P\u2009<\u2009.05. Deidentified individual-level data linked via unique AAMC identifiers were analyzed using Stata, version 15 (StataCorp LLC).We identified SCAEP participants in the Robert Wood Johnson Foundation Summer Medical and Dental Education Program (SMDEP), which is a cost-free, 6-week national program to strengthen academic proficiency and career development of students underrepresented in health care professionsThe study sample included 29\u2009456 graduates . A total of 15\u2009050 (51%) were women, 4375 (15%) were graduates from racial/ethnic groups that are underrepresented in medicine, and 4255 (14%) were FGCGs . Among 25 of SCAEPs have shown an increase in the likelihood of application and matriculation to medical school associated with SCAEP attendance. We observed an association between SCAEPs and increased student diversity and that SMDEP participants were more likely to report sustained career intentions to practice in underserved areas. Because career intention to practice in underserved areas at graduation has established predictive validity,6 our findings may inform medical schools\u2019 investments in programs to recruit diverse students whose career goals align with national needs to increase access to care.Previous studiesOur study was limited by small numbers of American Indian or Alaska Native only and Native Hawaiian or other Pacific Islander only graduates, precluding their examination as discrete groups. In addition, we could not further disaggregate the other SCAEPs , which limits generalizability of observations for this group. In the context of the current coronavirus disease 2019 (COVID-19) pandemic and recent activism in response to anti-Black racism, SCAEPs such as SMDEP may play a particular role in medical schools\u2019 efforts to recruit and educate a diverse physician workforce that will meet national health care needs."} +{"text": "Hepatocellular carcinoma (HCC) and pancreatic cancer (PC) belong to the most lethal malignancies worldwide. Despite advances in surgical techniques and perioperative multidisciplinary management, the prognosis of both carcinoma entities remains poor mainly because of rapid tumor progression and early dissemination with diagnosis in advanced tumor stages with poor sensitivity to current therapy regimens. Both highly heterogeneous visceral carcinomas exhibit unique somatic alterations, but share common driver genes and mutations as well. Recently, circulating tumor DNA (ctDNA) could be identified as a liquid biopsy tool with huge potential as non-invasive biomarker in early diagnosis and prognosis. CtDNA released from necrotic or apoptotic cells of primary tumors, metastasis, and circulating tumor cells can reveal genetic and epigenetic alterations with tumor-specific and individual mutation and methylation profiles. In this article, we focus on clinical impact of ctDNA as potential biomarker in patients with HCC and PC. Hepatocellular carcinoma (HCC) and pancreatic cancer (PC) represent two of the most challenging visceral malignancies in oncology with rising incidence and lack of reliable biomarkers for early diagnosis, prognosis, and therapy response. PC and HCC are estimated to become the second and third respective leading causes of cancer-related death in western countries by 2030 , Topoisomerase I inhibition by irinotecan, the DNA crosslinking agents oxaliplatin and cisplatin, and the tubulin inhibitor paclitaxel 1\u20133, platelet-derived growth factor receptor (PDGFR) beta, c-KIT, and RAF/mitogen-activated protein/MEK was the sole drug approved for the treatment of advanced HCC between 2007 and 2016 with a response rate of less than 5% and an extended median overall survival of 2.5 months DNA originates from normal cells exported by exosomes as well as from apoptotic and necrotic cells with highly fragmented, double-stranded DNA of approximately 150\u2013180 base pair fragments in size being released into the bloodstream. In 1948, Mandel and Metais first reported the presence of cfDNA in human circulation followed by detection in urine, saliva, and other body fluids DNA is becoming a research hotspot with high potential as liquid biopsy marker in cancer medicine and digital droplet PCR (ddPCR) are the most promising methods for the detection of mutations in liquid biopsies. In general, plasma samples are used in preference over serum because of lower concentrations of wild-type DNA in HCC patients Table . TERT pr. detected concurrent p15 and p16 methylation in 74% of ctDNA of 23 blood samples from 92% of HCC patients with tumor p15/p16 methylation , RASSF1A, and secreted frizzled-related protein 1 (SFRP1) resulted in an increased accuracy of 93% to differentiate between HCC and healthy controls and therapy stratification in advanced non-small cell lung cancer patients (Zhang et al. Overall, ctDNA mapping of somatic driver mutations and specific epigenetic alterations has great potential in early detection and dynamic monitoring of hepatic or pancreatic carcinomas to achieve a significant decrease of mortality. However, low sensitivity of current ctDNA assays rest a major challenge.So far, ctDNA analysis in PC and HCC could reveal high frequency of common key mutations as TP53 and CDKN2A. CTNNB1 and TERT mutations and aberrant methylation of RASSF1A and CDKN2A were detected in ctDNA of HCC patients, whereas high frequency of KRAS mutations was characteristic for PC. Prospective trial data based on sufficient sample size and defined entry criteria regarding the blood draw procedure and pre-analytical variables as well as standardization of experimental techniques that demonstrate the clinical utility of ctDNA assays in PC and HCC are required."} +{"text": "Pterocarya stenoptera is a common fast\u2010growing tree species often used in the ecological restoration of riverbanks and alpine forests in central and eastern China. Until now, the characteristics of the distribution of this species' habitat are poorly known as are the environmental factors that influence its preferred habitat. In the present study, the Maximum Entropy Modeling (Maxent) algorithm and the Genetic Algorithm for Ruleset Production (GARP) were used to establish the models for the potential distribution of this species by selecting 236 sites with known occurrences and 14 environmental variables. The results indicate that both models have good predictive power. Minimum temperature of coldest month (Bio6), mean temperature of warmest quarter (Bio10), annual precipitation (Bio12), and precipitation of driest month (Bio14) were important environmental variables influencing the prediction of the Maxent model. According to the models, the temperate and subtropical regions of eastern China had high environmental suitability for this species, where the species had been recorded. Under each climate change scenario, climatic suitability of the existing range of this species increased, and its climatic niche expanded geographically to the north and higher elevation. GARP predicted a more conservative expansion. The projected spatial and temporal patterns of P.\u00a0stenoptera can provide reference for the development of forest management and protection strategies.Climate change poses a serious threat to biodiversity. Predicting the effects of climate change on the distribution of a species' habitat can help humans address the potential threats which may change the scope and distribution of species. Minimum temperature of coldest month (Bio6), mean temperature of warmest quarter (Bio10), annual precipitation (Bio12), and precipitation of driest month (Bio14) were important environmental variables influencing the prediction of the Maxent model. Under each climate change scenario, climatic suitability of the existing range of this species increased, and its climatic niche expanded geographically toward farther north and higher elevation. The GARP predicted a more conservative expansion. The results will allow researchers to identify the future suitable habitat and help in the use, management, and cultivation of P.\u00a0stenoptera.To determine the potential geographical distribution and the environmental variables influencing habitat suitability for this species, we used Maxent and GARP modeling to predict the future distribution of 22.1http://www.tropicos.org/), the Global Biodiversity Information Facility (http://www.gbif.org) and the Chinese Virtual Herbarium (http://v5.cvh.org.cn/) database; the latter holds the plant distribution records of the main herbaria of China.

The positively selected mutations detected in IGF2BP2 likely affected the functionality of the encoded protein. IGF2BP2, which has been reported to simultaneously prolong life span and increase energy expenditure, could be responsible for the evolution of shortened MLS associated with the loss of flying ability.Acquisition or loss of flying ability is evolutionarily linked with maximum life span (MLS) in mammals and birds. Although ecological factors, such as extrinsic mortality, may lead to either shortened or extended life spans through natural selection, MLS is influenced by complex molecular and metabolic processes, and the genetic changes associated with flying ability that have led to either a longer or shorter MLS are unknown. Here, we examine the parallel evolution of flight in mammals and birds and investigate positively selected genes at branches where either the acquisition (in little brown bats and large flying foxes) or loss of flight abilities occurred. Although we found no shared genes under selection among all the branches of interest, 7 genes were found to be positively selected in 2 of the branches. Among the 7 genes, only Positively selected genes at the branches of interest. It has been proposed that species with lower extrinsic mortalities have longer life spans because they can invest in long\u2010term survival receptors may have contributed to the evolution of their long life spans and the little brown bat (Myotis lucifugus), as volant species with a longer MLS in mammals; and two penguins, the Ad\u00e9lie penguin (Pygoscelis adeliae) and the emperor penguin (Aptenodytes forsteri), and eight ratites, the common ostrich (Struthio camelus), the emu (Dromaius novaehollandiae), the great spotted kiwi (Apteryx haastii), the little spotted kiwi (Apteryx owenii), the okarito brown kiwi (Apteryx rowi), the greater rhea (Rhea americana), the lesser rhea (Rhea pennata), and the cassowary (Casuarius casuarius), as nonvolant birds with a shorter MLS. We then searched for positively selected genes among the different lineages to identify genes that evolved in parallel and are related to both flying and life span. Genes detected among multiple branches where changes in flying ability had occurred are discussed for their possible roles in energy expenditure and alteration in life spans.To shed light on the parallel evolution of either longer or shorter MLSs with that of either acquisition or loss of flight ability, it is necessary to examine candidate genes that have been subject to positive selection in multiple lineages of birds that have lost their flying ability in addition to those of mammals that have evolved the ability to fly. The purpose of our research was to detect positively selected genes at the branches where the acquisition or loss of flying ability occurred, using whole\u2010genome\u2010sequenced mammals and birds, and to explore the genes responsible for shorter or longer MLSs associated with the evolution of the loss or acquisition of flying ability.

Genomes of the zebra finch, emu, and the three kiwis were obtained from Ensembl 98 , reportedly the longest\u2010living bat, and the flightless brown kiwi were not included in our analysis as their assembled genome sequences included many gaps and a sufficient number of orthologous genes was not available.

A retrospective, uncontrolled, cross-sectional study of 31 Lassa fever survivors (62 eyes) who underwent an ophthalmic evaluation in January 2018 at the Kenema Government Hospital in Kenema, Sierra Leone was performed. Data collection included demographic information, ocular/systemic symptoms, visual acuity (VA), and ophthalmic examination findings. Main outcome measures included anterior and posterior segment ophthalmic manifestations and level of VA impairment in Lassa fever survivors. Anterior segment findings included cataract (18%) and pterygium (2%), while posterior segment manifestations consisted of glaucoma (6%), preretinal hemorrhage (2%), and lattice degeneration (2%). Findings suggestive of prior sequelae of uveitis included chorioretinal scarring (5%), retinal fibrosis (3%), and vitreous opacity (2%). Visual acuity was normal/mildly impaired in 53 eyes (85%), moderately impaired in 6 eyes (10%), and 3 eyes (5%) were considered blind by the World Health Organization (WHO) criteria. Median VA was worse in Lassa fever survivors with ophthalmic disease findings (p<0.0001) for both anterior segment (p<0.0001) and posterior segment disease (p<0.013). Untreated cataract was a significant cause of visual acuity impairment (p<0.0001). Lassa fever survivors in this cohort were found to have cataract and posterior segment findings that potentially represent sequelae of uveitis associated with visual impairment. Future studies are warranted to improve our understanding of the spectrum of ocular disease in this emerging infectious disease of public health consequence. Arenaviridae family. Lassa fever is endemic to the West Africa countries of Benin, Ghana, Liberia, Guinea, Mali, Sierra Leone and Nigeria, affecting 100,000 to 300,000 people annually, and causing approximately 5,000 deaths per year 19\u201350). The median time from the date of Lassa fever diagnosis to the date of ophthalmic examination was 10.03 years (IQR 6.0\u201312.0). Five patients (16.1%) reported eye symptoms including pain, redness, and blurry vision during the acute phase of Lassa fever. At the time of ophthalmic examination, Lassa fever survivors reported ocular symptoms including blurry vision (42%), itching (13%), pain (6%), redness (6%), tearing (6%), loss of near vision (3%), and floaters (3%) . Review Anterior segment findings included cataract (18%) and pterygium (2%). One patient had a traumatic cataract from penetrating corneal injury, which had self-sealed without surgical repair and showed evidence of uveitis with focal posterior synechiae . This siOphthalmic manifestations in the posterior segment included the presence of glaucomatous optic neuropathy (6%), chorioretinal scarring (5%), retinal fibrosis (3%), peripheral drusen (3%), preretinal hemorrhage (2%), lattice degeneration (2%), and vitreous opacity (2%) . There wVisual acuity was normal or mildly impaired in 53 eyes (85%), moderately impaired in 6 eyes (10%), and 3 eyes (5%) were considered blind according to the World Health Organization classification of visual impairment . The thrWe analyzed the impact of ocular structural complications on visual acuity, which are summarized in any ophthalmic abnormality by exam (p > 0.05). Individuals with any ocular abnormalities were likely to be older compared to patients evaluated without ocular findings . Patients who were older tended to report blurred vision symptoms than younger patients . Gender was not associated with the presence of ocular complications or blurred vision symptoms .A significant minority of Lassa fever survivors (42%) reported blurred vision and we thus assessed the relationship of this patient-reported symptom to visual acuity impairment and ophthalmic findings. No association was observed between individuals with reported blurred vision and at least moderate visual acuity impairment . In addition, no association was observed between blurred vision and evidence of Audiovestibular symptoms and joint pain have been reported in Lassa fever survivors and their relationship to ophthalmic disease was analyzed. Seven patients were found to have audiovestibular symptoms (23%) including 6 with hearing loss and 1 patient with tinnitus, which developed after acute Lassa fever. Hearing loss included bilateral disease (1), right ear (2), left ear (1) and unspecified (2). Hearing loss was not associated with patient-reported blurred vision or the presence of posterior segment or anterior segment disease findings . Joint pain was similarly unassociated with ocular findings (p > 0.05) in our series of patients, although like hearing loss, was observed in a modest proportion (26%) of patients evaluated.The ophthalmic sequelae of Lassa fever have not been well-characterized, and the aim of this study was to provide a preliminary investigation of the ophthalmic manifestations in Lassa fever survivors. Ocular involvement during the acute phase of Lassa fever has been reported to manifest as conjunctivitis, typically starting on day 7 of illness and lasting for a duration of 5 days . SubconjBlurry vision was a common visual complaint with over 40% of patients describing this symptom at the time of ophthalmic evaluation. The majority of patients (85%) had normal or mild vision impairment according to the WHO classification of visual impairment. While McCormick et al identified cases of uveitis with transient vision loss, we did not observe signs of active uveitis in our cohort of Lassa fever survivors who were evaluated . MoreoveThere are few reports in the literature documenting the prevalence and causes of visual impairment in the general population in West Africa. The Tema Eye Survey, a population-based cross-sectional study of 5,603 participants residing in an urban West African location, reported a 17.1% prevalence of visual impairment and 1.2% rate of blindness in Tema, Ghana, West Africa . RefractOther untreated ophthalmic conditions that were observed in our study of Lassa fever survivors included open globe trauma, cataract and advanced glaucoma. Specifically, cataract and end-stage glaucoma were identifiable causes of blindness (vision loss worse than 20/400) in three patients (9.7%). A dense mature cataract precluded view to the fundus in one of these patients, and thus it is unknown whether there were other posterior segment findings suggestive of cataract formation related to intraocular inflammation or if the cataract was merely age-related. The mechanism of glaucoma is unknown in the two patients with end-stage glaucoma and hand motions visual acuity; however, they did not have visible sequelae of prior ocular inflammation. In comparison, a retrospective study of a hospital population in Sierra Leone, West Africa conducted in 1989 and 1992 revealed that senile cataract was the major cause of blindness followed by uveitis despite a significant decrease in blindness from onchocerciasis . BlindneLong-term systemic symptoms were also present at the time of ophthalmologic examination, including joint pain (26%), hearing loss (16%), and headache (16%). Hearing loss is a well-documented and potentially profound sequelae of Lassa fever, and a literature review of five hospital-based and population-based studies of Lassa fever survivors revealed that approximately one-third (4%-75%) of Lassa virus-infected patients developed sudden sensorineural hearing loss .

A singlToxoplasma gondii. Selection bias was also a potential limitation, as patients may have presented for an ophthalmic examination primarily if they reported ocular symptoms. Future controlled, longitudinal studies with larger sample sizes are planned to characterize the prevalence of ocular disease and the spectrum of ophthalmic complications associated with Lassa fever.Limitations of our study include the cross-sectional, retrospective nature of the study.

Conversely, the vestibular mutant SERT-G402H merely displayed the high force population. These observations provide physical evidence for the existence of two binding sites in SERT. The dissociation rate constant of both binding sites was extracted by varying the dynamics of the force-probing experiments. Competition experiments revealed that the two sites are allosterically coupled and exert reciprocal modulation.Crystal structures and experiments relying on the tools of molecular pharmacology reported conflicting results on ligand binding sites in neurotransmitter/sodium symporters (NSS). We explored the number and functionality of ligand binding sites of NSS in a physiological setting by designing novel tools for atomic force microscopy (AFM). These allow for directly measuring the interaction forces between the serotonin transporter (SERT) and the antidepressant S-citalopram (S-CIT) on the single molecule level: the AFM cantilever tips were functionalized with S-CIT via a flexible polyethylene glycol (PEG) linker. The tip chemistry was validated by specific force measurements and recognition imaging on CHO cells.

Force sensing in physiological conditions allowed for the extraction of dynamic information, thus unequivocally documenting the existence of two binding sites in SERT. Furthermore, our force experiments revealed a positive allosteric effect on the S2 site induced by the binding of S-CIT at S1 site. Given the importance of allosteric regulation in biology and pharmacology, SMFS provides a unique approach to explore transient binding sites in clinically relevant membrane transporters for addressing the modulation of interaction forces between ligands and allosterically coupled binding sites.Indeed, such an allosterically enhanced binding strength of S-CIT at the S2 site could be a critical contribution for the capture of the S2 site by X-ray crystallography.

Knowledge about the spatial distribution of biodiversity and biological processes within wetlands provides essential baseline data for predicting and mitigating the effects of present and future environmental change on these critical ecosystems. To explore the potential for environmental DNA (eDNA) to provide such insights, we used 16S rRNA metabarcoding to characterise prokaryote communities and predict the distribution of prokaryote metabolic pathways in peats and sediments up to 4m below the surface across seven New Zealand wetlands. Our results reveal distinct vertical structuring of prokaryote communities and metabolic pathways in these wetlands. We also find evidence for differences in the relative abundance of certain metabolic pathways that may correspond to the degree of anthropogenic modification the wetlands have experienced. These patterns, specifically those for pathways related to aerobic respiration and the carbon cycle, can be explained predominantly by the expected effects of wetland drainage. Our study demonstrates that eDNA has the potential to be an important new tool for the assessment and monitoring of wetland health.

Use of therapy with IV iron and/or ESAs was identified among patients diagnosed with CKD and anemia. The study index quarter was the first quarter in 2006 during which the patient had primary or secondary diagnoses of both CKD and anemia. Based on the receipt of IV iron or ESA treatment in the index quarter, patients were classified into 1 of 4 treatment groups: IV iron and ESA; IV iron without ESA; ESA without IV iron; neither IV iron nor ESA. Therapy with oral iron was not measurable with this database. Clinical and economic outcomes, including the progression to advanced CKD stages, development of anemia, mortality, hospitalization, and net Medicare reimbursement for all-cause health care services, were examined for 1 year following the index quarter. Between-group differences were tested using Pearson chi-square for categorical variables and the Kruskal-Wallis nonparametric test for reimbursement. Multivariate logistic regression models were estimated to assess the associations of mortality, inpatient hospitalization, skilled nursing facility (SNF) admission, and hospice care with treatment regimen, controlling for patient demographic and clinical characteristics.Of the 4,310 study patients with both CKD and anemia, 2,913 (67.6%) received neither IV iron nor ESA; 984 (22.8%) received ESA without IV iron; 277 (6.4%) received IV iron and ESA; and 136 (3.2%) received IV iron without ESA in the index quarter. Logistic regression analyses showed that patients receiving neither IV iron nor ESA (reference group) were at increased risk of death compared with patients receiving both IV iron and ESA .

The phyB-PIF hub is at the core of all shade-avoidance responses, whilst other photosensory receptors and transcription factors contribute in a context-specific manner. CONSTITUTIVELY PHOTOMORPHOGENIC1 is a master regulator of this hub, indirectly stabilizing PIFs and targeting negative regulators of shade avoidance for degradation. Warm temperatures reduce the activity of phyB, which operates as a temperature sensor and further increases the activities of PIF4 and PIF7 by independent temperature sensing mechanisms. The signaling network controlling shade avoidance is not buffered against climate change; rather, it integrates information about shade, temperature, salinity, drought, and likely flooding. We, therefore, predict that climate change will exacerbate shade-induced growth responses in some regions of the planet while limiting the growth potential in others.When exposed to changes in the light environment caused by neighboring vegetation, shade-avoiding plants modify their growth and/or developmental patterns to access more sunlight. In Arabidopsis ( The signaling network involved in shade avoidance responses integrates information from environmental variables such as temperature, water availability, and salinity. Shade avoidance responses are changes in plant growth and/or developmental patterns elicited by modifications of the light environment caused by neighboring vegetation. Their function is to increase access to sunlight and reduce the risk of future shade .There are four strategies to achieve these goals: (a) To overtop neighbors, elevating the foliage above vegetation shade; (b) to move the position of the foliage on the horizontal plane away from the shade of neighbors; (c) to reduce the proportion of the foliage placed at the shaded base of the canopy; and (d) to modify the phenology to elude the time when deep shade is present.The growth and developmental responses inherent to each one of these strategies, respectively, include (a) enhanced elongation of the stem or petioles and the shift of leaves to a more erect position (enhanced leaf hyponasty); (b) asymmetric growth of the stem or the leaves (the phototropic response of light-grown seedlings can be included within this class of shade avoidance responses) and asymmetric branching; (c) the inhibition of branching at the base of the plant, the reduction of expansion of shaded leaves and the advanced senescence of basal leaves; and (d) the accelerated transition to reproduction (flowering) to complete the life cycle before shade becomes too deep and the delayed seed germination until shade disappears.Glycine max) (Helianthus annuus) (Triticum aestivum) (Hordeum vulgare) (Sorghum bicolor) (Zea mays) and sunflower and sunf annuus) , reduce estivum) , barley vulgare) , and sorbicolor) , and enhbicolor) and orieea mays) and sunfea mays) .

Tight glycemic control with intensive insulin therapy has been suggested to reduce the risk of such complications in several diabetes populations; however, such an approach can also be associated with risks and challenges. There are currently several modalities available to deliver insulin and monitor glucose levels to achieve glycemic goals in diabetic patients. In July 2012, the Agency for Healthcare Research and Quality (AHRQ) published a systematic review on the comparative effectiveness of insulin delivery systems and glucose-monitoring modalities in diabetic patients receiving intensive insulin therapy. Studies from 44 publications included in the review compared the effects of continuous subcutaneous insulin infusion (CSII) with multiple daily injections (MDI) and/or real time-continuous glucose monitoring (rt-CGM) with self-monitoring of blood glucose (SMBG) among children, adolescents, or adults with either type 1 (T1DM) or type 2 diabetes (T2DM), or pregnant women with pre-existing diabetes (either T1DM or T2DM). This comparative effectiveness review evaluated which modality results in improved glycemic control, less hypoglycemia, better quality of life, and/or improved clinical outcomes. The numerous technologies and the challenges that clinicians face when determining which patient population may benefit from different insulin delivery systems and glucose-monitoring approaches motivated AHRQ to synthesize the available information to assist health professionals in making evidence-based practice decisions for their patients. The review also delineates advances in insulin delivery and glucose-monitoring systems, practical methods to achieve tight glycemic control and strategies to minimize associated risks, as well as highlights gaps in research and areas that need to be addressed in the future.To (a) educate health care professionals on the findings from AHRQ\u2019s 2012 comparative effectiveness review on insulin delivery and glucose-monitoring modalities in patients with diabetes; (b) apply review findings to make treatment decisions in clinical practice; and (c) identify shortcomings in the current research and future directions relating to the comparative effectiveness of insulin delivery and glucose-monitoring modalities for patients with diabetes.The AHRQ systematic review of randomized clinical trials reveals that both insulin delivery modalities (CSII and MDI) demonstrate similar effectiveness on glycemic control and severe hypoglycemia in children and adolescents with T1DM and in adults with T2DM. In adults with T1DM, hemoglobin A1c decreased more with CSII than with MDI with low strength of evidence, but one study heavily influenced these results. In children and adults with T1DM, the use of CSII was associated with improved quality of life compared with MDI, with low strength of evidence, while there was insufficient strength of evidence to make conclusions regarding the quality of life for adults with T2DM. The study investigators suggest that the modality to deliver intensive insulin therapy can be individualized to patient preference in order to maximize quality of life. On all measured outcomes, there was insufficient or low strength of evidence regarding pregnant women with pre-existing diabetes.The AHRQ investigators found studies comparing the effectiveness of glucose-monitoring modalities in individuals with T1DM only. The systematic review demonstrates that rt-CGM is associated with greater lowering of A1c compared with SMBG (high strength of evidence) without affecting the risk of severe hypoglycemia (low strength of evidence) or quality of life (low strength of evidence) in nonpregnant individuals with T1DM, particularly when compliance with device use is high. Additional findings suggest that the use of sensor-augmented insulin pumps (rt-CGM + CSII) is superior to the use of MDI/SMBG use in lowering A1c in nonpregnant individuals with T1DM (moderate strength of evidence). Comparison of other outcome measures did not yield firm conclusions due to low or insufficient evidence."} +{"text": "Retirement from sport is a life transition that has significant implications for athletes\u2019 physical and mental health, as well as their social and professional development. Although extensive work has been done to review the retirement experiences of athletes, relatively less work has been done to examine and reflect on this expansive body of literature with a pragmatic aim of deciding what needs to happen to better support retiring athletes. This study used scoping review methodology to review current academic reviews, gray literature articles, and support programs on athletic retirement. This review followed the Joanna Briggs Institute reviewer\u2019s manual guide on scoping reviews and adhered to the PRISMA-ScR checklist. Academic articles were identified from PubMed, Embase, Web of Science and Scopus. Gray literature articles and support programs were identified using advanced Google searches. This study identified 23 academic reviews, 44 gray literature articles, and 15 support programs. Generally, the results suggest that athletic retirement encompasses a drastic shift in identity, a loss of social networks, a lack of career ambitions, and potential risks to physical and mental health. While there was a gap in the academic literature regarding practical strategies to support retiring athletes, the gray literature suggests many creative ideas. Stepwise programming may be beneficial to help athletes: (a) make sense of their athletic experience and see retirement as an ongoing process; (b) develop a well-rounded sense of self identity and understand how to apply their unique skills and strengths in new ways; (3) gain control over their retirement transition by establishing a clear plan and adjusting to new routines and opportunities; and (4) normalize the transition experience by \u201cliving in the next\u201d and building confidence in new life directions. Future research may benefit from developing and evaluating more programming to support athletes through the retirement transition. Retirement from a high-performance sport is a life transition that has significant implications for physical and mental health, as well as social and professional development . AthletiReviews of the academic literature on athletic retirement have generated mixed findings regarding the impact of retirement from sport on mental and physical health , 11, 12.Several approaches can be used to examine individuals\u2019 retirement experiences, including approaches from the field of social gerontology where retirement is seen as a career transition that results in the termination of paid work \u201326, and Regardless of the approach taken, there appears to have been extensive work done to review the retirement experiences of athletes in both academic and non-academic settings. Despite these important advancements, relatively less time has been taken to examine and reflect on the expansive body of literature, with a pragmatic aim of deciding what needs to happen next to better support retiring athletes. Despite numerous evidence syntheses, athletes still face physical, mental, and emotional struggles after retirement with a lack of appropriate supports. Though nearly every move an athlete makes is scrutinized, relatively little attention is paid to an athlete\u2019s transition to life after sport. In light of the current state of the literature, this review presents a scoping review of the athlete retirement transition experience, focusing on existing reviews of the academic and gray literature, with a pragmatic aim to improve future practices.The objective of this scoping review is to review other academic reviews, gray literature articles, and support programs that address athletes\u2019 experience transiting into life after sport, with a pragmatic aim of identifying how athletes can be supported through the retirement process. To encompass a wide range of athlete experiences, this review includes both amateur and professional athletes. This review will address the following specific questions: (1) what are the main characteristics of academic and gray literature studies that review athletes\u2019 transition experiences? (2) what does the current body of synthesized literature say about the key barriers and enablers to a successful athletic retirement transition? (3) what does the current body of synthesized literature say about the negative and positive impacts of athletic retirement? and (4) what does the current body of synthesized literature say about the programming needed to better support athletes\u2019 transition into life after sport?other reviews as our primary evidence source [We followed the Joanna Briggs Institute reviewer\u2019s manual guide on scoping reviews, with a focus on e source . We wante source .rd, 2022, with search terms related to athletes, retirement, and reviews. Results were limited to English. We ensured our search was specific enough to yield highly relevant reviews we knew we wanted to include. To find relevant gray literature sources, several targeted advanced Google searches were conducted between August and September 2022. The advanced Google searches included search terms related to athletes, retirement, and organizations that our research team identified as highly relevant . For pragmatic reasons, only the first 50 sources were used for each advanced Google search. Our full search strategy can be viewed in The search strategy was developed by the lead authors (PV and MS). To find relevant academic sources, a search of the databases PubMed, Embase, Web of Science and Scopus were conducted on July 23For our academic search, included papers were restricted to full-text, original, peer-reviewed evidence syntheses . The reviews had to focus on athletes as their primary population . We decided to include amateur and professional athletes to encompass the wide range of athletes who experience the retirement transition process. The reviews also had to have a clear focus on athletes\u2019 retirement or transition into life after competitive sport . Although we did not constrict our paper eligibility by the type of review, the review had to include a clear search strategy . For our gray literature search, advanced google searches either identified: (a) programs that support athlete transitions, or (b) non-academic articles about athlete transitions. No restrictions were put on the date or location of included sources, although certain search terms focused on American and Canadian programs specifically.Reviews from the academic database searches were handled using Covidence reference management software. Reviews were deduplicated and imported for a 2-level screening process. During level 1 screening, titles and abstracts were double screened by two reviewers (AR and LA) using the eligibility criteria. Publications with titles and abstracts not meeting the eligibility criteria were excluded. During level 2 screening, full-text papers that passed level 1 were screened by the same two reviewers (AR and LA). Studies that met the eligibility criteria were included for full data extraction. Discrepancies during level 1 and 2 screening were discussed over several meetings with final decisions on screening made by PV. Programs and articles from the gray literature search were handled using google sheets. One reviewer (JC) scanned the advanced google searches for relevant programs and articles using the eligibility criteria. The reviewer copied and pasted relevant programs and articles into a google sheet, which was then reviewed by PV. After discussion between JC and PV on the included programs and articles, the final gray literature source inclusion was finalized by PV.Data from the included academic reviews were extracted using a data extraction form that included information on reviews\u2019 title, author, year, journal, review type, study objective, databases searched, date range searched, population limitations, setting limitations, number of papers included, paper types included , paper locations, paper populations , and the key thematic constructs identified in the review. The thematic information we extracted included information on (a) the barriers and enablers of athlete retirement transitions, and (b) the negative and positive outcomes of athletic retirement. Barriers to retirement transitions and negative outcomes after retirement were indicated using a negative text symbol high athletic identity, or (-) worsening anxiety and depression). Enablers and positive outcomes were indicated using a positive sign planned retirement, or (+) relief from pressure and expectation). The data was initially extracted by one reviewer (IH) and then reviewed and refined by the lead authors (MS and PV).articles were extracted using a data extraction form that included information on the title, author, host origination, organization mission, organization location, key themes about (a) athletes\u2019 unique experiences, (b) athletes transition challenges and enablers, and (c) strategies or programs for improving the transition experience. Data from included gray literature programs were extracted using a data extraction form that included information on the title, author, host origination, organization mission, organization location, and the program\u2019s offerings for athletes . The data was initially extracted by one reviewer (JC) and then reviewed and refined by the lead authors (MS and PV).Data from included gray literature sources were extracted using two different data extraction forms. Data from the gray literature The lead author (PV) completed a descriptive analysis of the data collected from the included papers that aligned with the objectives of this review. For the academic sources, we start by presenting an overview of the review characteristics. We then present a summary of the major findings across the reviews depending on the review topic reviews that explore the general psychosocial experiences of retiring athletes, (b) reviews that specifically explore the cognitive and mental health experiences of retiring athletes, and (c) reviews that specifically explore the musculoskeletal and cardiovascular experiences of retiring athletes. For the gray literature sources, we first present an overview of the gray literature source characteristics. We then present a summary of the major themes across the gray literature sources, including summaries about (a) the unique experiences of athletes themselves, (b) athletes\u2019 experiences with retirement, specifically, and (c) support programming for retiring athletes. All reviews were published in the last 10 years (between 2013\u20132022). In total, 10 reviews explored the general retirement experiences of athletes, 8 reviews explored athletic retirement with concussion, cognitive, and mental health concerns, and 5 reviews explored athletic retirement with musculoskeletal and cardiovascular health issues. The majority of the reviews were systematic reviews (n = 20), in addition there was a scoping review (n = 1), a critical review (n = 1), and a literature review (n = 1). Most reviews combined athletes from multiple different sports (n = 14); the remaining reviews focused on soccer players (n = 5), cricket players (n = 1), rugby players (n = 1), American football players (n = 1), and gymnasts (n = 1). Most reviews included athletes from multiple countries (n = 21), however, 2 reviews specifically focused on athletes in the United States. The number of articles examined in each review ranged from 4 articles to 219 articles, with the mode being 17 articles. Most reviews included male and female participants (n = 15), with the exception of reviews that focused on females only (n = 1), males only (n = 3), or did not report on gender (n = 4). Most reviews focused on quantitative studies (n = 16); however, several reviews included multiple study designs (n = 5). Only 1 review did not report the designs of the studies they included. The majority of reviews focused on professional and elite athletes (n = 11); several reviews featured sub-elite athletes (n = 6), such as club or high school athletes, and a substantial number of reviews did not report the level of the athletes in the studies included (n = 7).We identified 23 academic reviews of literature examining the retirement transitions of athletes. A detailed description of the academic reviews included in this overarching review is provided in the Among the 10 reviews that explored the general retirement experiences of athletes, we identified numerous barriers and facilitators that affected athletes\u2019 ability to smoothly transition into life after sport. Barriers included: (1) having a high athletic identity; (2) high perfectionism and comparison; (3) athletic career dissatisfaction; (4) involuntary retirement ; (5) amount of other life changes occurring at the same time as retirement; (6) despair about future career; (7) lack of coping strategies; (8) low social support; (9) lack of transition planning; (10) education and resource dissatisfaction; (11) previous concussions; (12) raising body mass index; and (13) onset of osteoarthritis. Facilitators included: (1) having a good sport-life balance ; (2) positive self-perception and self-control; (3) athletic career satisfaction; (4) voluntariness of retirement; (5) gradual reduction of training; (6) length of time since retirement; (7) retirement planning; (8) support program involvement; (9) planned occupation after retirement ; (10) educational attainment; (11) financial planning; (12) social support network; (13) continued relationships with coaching staff; (14) strong coping strategies crisis preparedness.In addition to barriers and facilitators that affected athletes\u2019 retirement transition, we also identified numerous negative and positive impacts of athletic retirement itself. Negative impacts included: (1) worsening anxiety and depression; (2) feelings of burnout; (3) feelings of grief, loss, and void; (4) sleep disturbance and distress; (5) adverse alcohol use; (6) adverse smoking behaviours; (7) brain atrophy and dementia; (8) difficulty establishing new a lifestyle routine; (9) adverse nutrition behaviour; (10) disordered eating; (11) body dissatisfaction; (12) compensatory exercise; (13) high incidence of osteoarthritis incidence; (14) high incidence of join pain/back pain; and (15) high incidence of skin cancers. Positive impacts included: (1) relief from pressure and expectation; (2) high capacity for resilience and toughness; (3) greater or similar long-term quality of life; (4) greater capacity in certain mental proficiencies; and (5) difficulties with transition will fade over time.Among the 8 reviews that explored the relationship between athletic retirement and cognitive or mental health outcomes, several reviews examined and found that history of concussion during sport was a significant risk factor for cognitive impairment and mental health issues among retired athletes. Only one review reported mixed findings about this association . Most reAmong the 5 reviews that explored the relationship between athletic retirement and musculoskeletal and cardiovascular health issues, 4 reviews specifically focused on osteoarthritis prevalence among retired athletes, while 1 review focused on cardiovascular disease risk . Among tS3 and We identified 15 unique programs from our gray literature search that provide information about support for athletes through their athletic retirement transition. In addition, we identified 44 unique non-academic articles that describe and provide practical advice on athletic retirement transitions. Athlete retirement transition programs were based in different regions including, Canada (n = 7), the United Kingdom (n = 2), the United States (n = 2), Australia (n = 1), and South Africa (n = 1); while some programs had a clear global presence (n = 2). A full description of the programs and articles we identified in the gray literature search can be viewed in the Based on our analyses of the gray literature, 10 features emerged as unique aspects of the athlete experience: (1) living in a highly structured environment ; (2) living in a high pressure and stimulating environment ; (3) athletics is experienced as a way of life ; (4) high identity association with being an athlete ; (5) young career termination ; (6) high focus on body function and image ; (7) experiencing injury and/or significant bodily changes ; (8) large personal sacrifices during their career ; (9) unique financial situations ; and (10) gaining distinctive skillsets that can be transferable to other life circumstances .In terms of the athletic retirement transition, 10 key challenges and 5 key opportunities emerged from the gray literature. Challenges include: (1) athletic termination as a crisis ; (2) athletic retirement as a long process, not a quick event ; (3) loss of identity ; (4) lack of purpose in day-to-day life ; (5) lack of stimulation and psychological demands ; (6) loss of significant relationships ; (7) physical adaptations ; (8) financial concerns ; (9) mental health issues, ; and (10) substance use concerns. Athletes\u2019 transition opportunities relate to: (1) exploring new social networks and lifestyle opportunities ; (2) exploring other career interests ; (3) having the chance to unwind ; (4) the stamina and strength gained in athletics ; and (5) being psychologically disciplined and accountable .Factors that influence whether an athlete has a positive or negative transition experience were found to be context dependent and related to issues such as: (1) voluntariness of retirement; (2) timing of retirement; (3) duration of the transition; (4) amount of other life changes during retirement; (5) positive or negative reflections on athletic career; (6) financial and career planning for retirement; (7) fitness and dietary planning for retirement; (8) personal brand built through athletics; (9) high athletic identity association; (10) ongoing injury issues; and (11) prioritization of retirement planning.The primary themes that emerged in relation to athlete retirement transition supports include the deliverer of support, the receiver of support, the delivery mode of support, and the content of support. Regarding the deliverer of the support, many different groups provided athletes with support, including: (1) athletic organizations; (2) third-party organizations ; (3) sports psychologists and counsellors; (4) family, friends, mentors, and peers; and (5) coaching staff and other team personnel . Regarding the receiver of supports, many different groups also accepted support, including (1) athletes themselves; (2) coaching staff; (3) athletic organizations; and (4) parents, family, friends, and partners. Regarding the delivery mode of support, avenues tend to be resource-based or systems-based . Resource-based supports include: (1) resource repositories; (2) educational information; (3) employment lists; (4) extracurricular activities lists; (5) educational opportunities lists; (6) videos with education/advice; (7) podcasts sharing lived experiences; (8) speaker series sharing lived experiences; (9) social media stories; (10) assessment tools; (11) reflection workbooks; and (12) guided journaling. Systems-based provisions include: (1) person-to-person support (online or in-person); (2) email or text-based support; (3) stepwise multicomponent programming; (4) team-integrated programming; (5) small group workshops; (6) membership to a community network; and (7) conferences or retreats. Regarding the content of support, the following issues were addressed: (1) personal wellbeing; (2) identity shifting; (3) mental health; (4) social networks; (5) personal relationships; (6) career building; (7) educational development; (8) physical health; (9) diet and exercise; (10) financial planning; (11) stories about others lived experiences; (12) education about transitioning; (13) personalized sports psychology; and (14) stepwise programming.S5 Table.Stepwise programming tended to include multifaceted interventions that featured the following steps: (1) come to terms with their retirement and see the retirement transition as a process; (2) develop a well-rounded sense of self identity and understand how to apply their unique skills and strengths in a new setting; (3) gain control over their retirement transition by establishing a future plan and adjusting to new routines and opportunities; and (4) normalize the transition experience by \u201cliving in the next\u201d and building confidence in new life direction. The contents of these steps have been fully detailed in high athletic identity is consistently associated with difficulties in transitioning into life after sport. Among elite athletes, it is not uncommon for their social networks, career ambitions, physical goals, psychological stimulation, and sense of self-worth to be distinctly tied to their sport [This paper presents a scoping review of the synthesized academic and gray literature regarding athlete retirement transitions.

Developing interests outside of sport and making time to develop contingency plans for life after sport helped ameliorate the transition. A second notable enabler was that athletes who can gain a sense of perceived control over their athletic termination, and gradually reduced their athletic participation, are able to transition better into retirement. Although supporting athletes to maintain balance, plan for their retirement, and gradually detrain themselves may seem counterintuitive to sports organizations who want the most out of their current athletes, our paper indicates that athletes who plan for retirement may actually perform better while still competing.Although identity loss, career regret, and abrupt lifestyle modifications were common conditions among retiring athletes, several key factors emerged across the academic literature as enablers of positive retirement transitions. The first notable enabler was that athletes who create a While much attention has been placed on the need to enhance athlete mental health and wellbeing , 53, lescognitive impairment, mental health issues, and osteoarthritis complications [Across the synthesized literature is a consensus that retiring athletes are at a particularly high risk of experiencing ications , 7, 36. a wide range of supports from different sources in order to address different needs. Stepwise programming, where athletes work through a series of ongoing interventions to prepare for a retirement transition, emerged as a robust enabler of a positive transition experience. Gradual, longstanding, embedded investments into retirement planning may be highly advantageous for improving athlete retirement transition outcomes. Researchers and practitioners may deeply benefit from investigating the mechanisms that best support the development of a well-rounded sense of self throughout an individual\u2019s athletic career and through the retirement transition experience.Despite indicating that retirement planning facilitated a better transition to athletic retirement, a clear gap in the academic literature exists with regard to how to develop and implement specific strategies for retirement planning based on sport and level. Fortunately, much of the gray literature focuses on these specific details, suggesting a multitude of creative ideas for how to better support athletes transition into life after sport. What is clear across the gray literature is that athletes need This review is the first of its kind to examine existing review articles from academic literature as well as current evidence from gray literature on retirement from sport. Limitations of this review include that we only included studies published in English and therefore may have excluded potential studies published in a different language. In an effort to be inclusive of the existing literature on athletic retirement, our review incorporates reviews of studies that combine different types of sport, multiple geographic regions, individuals of varying gender, and combines data on professional as well amateur athletes. Retirement experiences are likely to differ based on factors like these. Future research may benefit from focusing on developing and evaluating retirement support interventions based on characteristics of the individual athlete, the sport, as well as regional variations and other contextual factors.This review scopes the current synthesized academic and gray literature on athlete retirement transitions, with a pragmatic focus on how retiring athletes can be better supported. We identified and examined 23 academic reviews of literature examining the retirement transitions of athletes, 15 unique programs from gray literature that aimed to provide information about support to athletes through their athletic retirement transition experience, and 44 distinct non-academic articles that described and provided practical advice on the athletic retirement transition. The literature illustrates that feelings of loss, identity crisis, career regret, and difficulties with abrupt lifestyle modifications are common experiences in an athlete\u2019s retirement transition. While the academic review literature presented a gap in evaluating programs that aim to ameliorate athletic retirement, the gray literature provided multiple creative ideas for how to improve programming to support athletes\u2019 transition into life beyond sport.S1 Checklist(PDF)Click here for additional data file.S1 Table(DOCX)Click here for additional data file.S2 Table(DOCX)Click here for additional data file.S3 Table(DOCX)Click here for additional data file.S4 Table(DOCX)Click here for additional data file.S5 Table(DOCX)Click here for additional data file."} +{"text": "We review the latest information related to the control of fruit softening in tomato and where relevant compare the events with texture changes in other fleshy fruits. Development of an acceptable texture is essential for consumer acceptance, but also determines the postharvest life of fruits. The complex modern supply chain demands effective control of shelf life in tomato without compromising colour and flavour.Solanum lycopersicum) are discussed with respect to hormonal cues, epigenetic regulation and transcriptional modulation of cell wall structure-related genes. In the last section we focus on the biochemical changes closely linked with softening in tomato including key aspects of cell wall disassembly. Some important elements of the softening process have been identified, but our understanding of the mechanistic basis of the process in tomato and other fruits remains incomplete, especially the precise relationship between changes in cell wall structure and alterations in fruit texture.The control of softening and ripening in tomato ( Solanum lycopersicum) and other fruits is essential to the successful function of the modern fresh market supply chain. Substantial losses during transportation, susceptibility to post harvest diseases and limited keeping quality, result from fruits that ripen and soften rapidly. This has led to the use of a range of natural ripening mutations in commercial tomato breeding that slow the ripening and softening processes. The best known of these is the ripening inhibitor (rin) mutation. The use of the rin mutation in commercial practice has been very important in extending tomato shelf life, but it has detrimental effects on colour and flavour and downstream genes Fig.\u00a0.Fig. 1HPlant hormones, such as ethylene, act as endogenous and exogenous cues that govern the transition stage from fruit development to ripening. Extensive studies have shown that fruit ripening is modulated by a complicated network of feedback and crosstalk among different phytohormones including ethylene, abscisic acid (ABA) and auxin and ABA 8\u2032-HYDROXYLASE (SlCYP707A2) genes, which are genes involved in ABA biosynthesis and catabolism, resulted in elevated pectin levels and improved texture and shelf life and several genes encoding major cell wall catabolic enzymes were down regulated , a gene which encodes an ABA receptor, has revealed a role for SlPYL9 in regulating ABA signalling and ripening in tomato by affecting expression of ripening-related genes involved in ethylene production and cell wall modification , \u03b2-GALACTOSIDASE (Fa\u03b2GAL4) are positively regulated by ABA and negatively regulated by auxin , CELLULASE 1 (CEL1), and CELLULASE 2 (CEL2) were significantly up-regulated by ABA treatments, thus accelerating ripening in strawberry within the QTL was cloned. This FIS1 gene encodes a GA2-oxidase, an enzyme that inactivates endogenous GAs and their precursors also participate in modulating tomato fruit ripening via an interplay with ethylene. In several recent studies GA has been demonstrated to play a negative role in regulating tomato ripening. It is associated with suppression of the expression of ripening associated transcription factors and inhibiting ethylene production , and RNA methylation. Many of these events have now been shown to be associated with the progression of normal ripening and softening in tomato and other fruits subfamily played a positive role in regulating fruit softening through the activation of the same set of cell wall related genes regulated by SlHDA1/3 proteins within the polycomb repressive complex act as repressors of gene expression via histone modifications , non-ripening (nor) and Colourless non-ripening (Cnr) , ENDO--\u0392-MANNANASE 4 (LeMAN4) and \u03b1-EXPANSIN 1 (LeEXP1), CEL2, XYLAN 1,4-BETA-XYLOSIDASE1 (XYL1) was highly ripening-related. Repression of SlFSR significantly reduced the expression of multiple cell wall modification-related genes including PL, PG, TBG4, CEL2, XYL1, PECTIN ESTERASE (PE), MANNOSIDASE (MAN1), XYLOGLUCAN ENDOTRANSGLUCOSYLASE/HYDROLASE (XTH5) and EXP1, and prolonged shelf life, but did not influence other aspects of fruit ripening. These observations reveal the potential role of SlFSR in targeted control of tomato fruit shelf life by regulating cell wall metabolism TF, SlLOB1 has been shown by Shi to act as a transcriptional activator of a broad suite of cell wall\u2013related genes and to control softening were direct targets of SlHY5. However, the interplay between SlHY5 and these regulators needs further investigation in Arabidopsis (Wang et al., In a similar way to the pectin domain, disassembly of the hemicellulose and cellulose domains in the wall also appear to be a common feature of ripening in tomato and other fruits, but the contribution of these events to texture changes is even less well understood (Pos\u00e9 et al., Cell wall enzymes and other factors - In both tomato and strawberry the expression of genes encoding enzymes with PL activity has been demonstrated to be important in softening of these fruits. In the absence of PL expression, tomato fruit softened more slowly and HG was retained at cell junctions in the pericarp (Uluisik et al., The action of PL on wall mechanical properties has been studied in onion cells. Here lateral mobility of cellulose microfibrils was greatly increased at the nm-scale after PL treatment. However, concomitant effects on wall loosening and tensile properties were absent (Zhang et al., EXP1 is silenced (Brummell et al., EXP1 expression alters the extent of pectin depolymersation (Brummell et al., EXP1 has been shown to be important in tomato softening and there is an inhibitory effect on the process when SlLOB1 (Shi et al., EXP1 are strongly suppressed in SILOB1 RNA interference lines and induced in SlLOB1-overexpressing fruits.

Myeloid sarcoma disrupts the normal architecture of its surrounding tissues. When it forms in long bones, it can cause their pathological fracture. We recently experienced a rare case of MDS presenting with myeloid sarcoma in the femur that eventually resulted in its pathological fracture. Detailed chromosomal analysis of the bone marrow cells suggested emergence of myeloid sarcoma during the fast-paced progression of MDS just after acquiring trisomy 22. A comprehensive review of previous cases of myeloid sarcoma-associated pathological fracture indicated possible involvement of structural rearrangements of chromosomes 9 and 22. Management of myeloid sarcoma should continue to improve, and clinicians should note that myeloid sarcoma with specific chromosomal alterations needs extra medical attention to prevent pathological fracture. Myeloid sarcoma is a tumor mass consisting of myeloblasts with or without maturation involving any anatomical site. Most often, myeloid sarcoma is formed in patients with acute myeloid leukemia (AML), either at the time of diagnosis, during or after chemotherapy. This medical condition is well established in AML patients with recurrent genetic abnormalities, especially in cases of core binding factor AML that are characterized by the presence of either t8;21) or inv(16) scan was immediately taken, but did not locate any origins of fever.

It sometimes develops as a de novo isolated sarcoma without bone marrow involvement . Besides, extensive review of the past literatures on myeloid sarcoma-associated pathological fractures, we have identified 18 cases that had been reported with description of the results of cytogenetic analyses. In a sharp contrast to the chromosomal alterations seen in myeloid sarcoma in general, our detailed review elucidated that the incidence of t in myeloid sarcoma with pathological fractures (8/19 cases) is considered to be much higher than expected. Thus, we suspect the potential yet vital role of chromosomes 9 and/or 22 alterations in the development of myeloid sarcoma-associated pathological fractures. Given that the present case developed myeloid sarcoma soon after the immature myeloid cells acquired additional chromosomal alteration of\u2009+\u200922 (Fig.\u00a0As shown in Table 1In summary, we have experienced a rare case of MDS presented with a myeloid sarcoma in the right femur that eventually resulted in its pathological fracture. Reviewing the past cases, the possible involvement of the rearrangements of chromosomes 9 and 22 is suspected in the occurrence of myeloid sarcoma-associated pathological fractures. To seek the optimal management of myeloid sarcomas and prevention of associated complications, clinicians are encouraged to pay extra medical attention to the myeloid sarcoma cases involving chromosomes 9 or 22 alterations."} +{"text": "This cross-sectional study assesses the prevalence of conflicts of interest (COI) associated with guideline-recommended drugs among Infectious Diseases Society of America clinical practice guideline authors and compliance with the Council on Medical Specialty Societies and Institute of Medicine guidelines. The prevalence and nature of COI among authors of infectious diseases CPGs are poorly understood. We assessed the prevalence of COI associated with guideline-recommended drugs among Infectious Diseases Society of America (IDSA) CPG authors and compliance with Council on Medical Specialty Societies (CMSS) and Institute of Medicine (IOM) guidelines.5Conflicts of interest (COI) among clinical practice guideline (CPG) authors are commonSTROBE) reporting guideline and was determined to be exempt by the HealthPartners institutional review board because it was non\u2013human participants research.In this cross-sectional study, we searched all IDSA CPGs from June 1, 2017, to March 31, 2022 (N\u2009=\u200937). We excluded guidelines not published primarily by IDSA (n\u2009=\u200917) and guidelines without recommendations regarding specific antimicrobials (n\u2009=\u200910). We identified all CPG authors, their status as chair or co-chair, disclosed relationships, and relationship time frames. We included relationships only with pharmaceutical companies that developed or sold drugs. We extracted all drugs recommended in each CPG and excluded drugs recommended only in a clinical trial or sold only outside the US. We searched US Food and Drug Administration websites to identify drug manufacturers and approval dates. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology and a pharmaceutical company if the company manufactured a guideline-recommended drug at the time of publication. Companies associated with a manufacturer as a subsidiary or acquisition were included.

This idea may have motivated the curiosity of Zhu and colleagues to interrogate how the inheritance of somatic phenotypes is underscored by the gene expression modulatory activity of SWI/SNF subunits that linger at mitosis.1The SWI/SNF or BAF complexes are chromatin remodelers assembled on a modular basis and in a context-specific manner to dictate gene expression patterns that influence cell state and function.1 employed a biochemical fractionation strategy to investigate the presence, subcellular localization, and interaction of SWI/SNF complexes with chromatin in synchronized mouse embryonic stem cells spanning the cell cycle. It was identified that SMARCB1 and SMARCE1 were bound to mitotic chromatin, whereas other SWI/SNF subunits, including SMARCA4 (Brg1), were disengaged or residually bound. They subsequently used live cell imaging to substantiate the observation by in situ visualization of mitotic chromatin localization of SMARCB1 and SMARCE1 alongside SOX2, a classic mitotic chromatin-bound factor. The outcome of chromatin immunoprecipitation and sequencing, which was tweaked by Cut & Run sequencing approach, revealed the promoter region as the preferential genomic location of SMARCB1 and SMARCE1 in mitotic cells and BAF170 (SMARCC2) as the earliest assembled subunits of SWI/SNF complex5 may benefit expanding the range of SWI/SNF subunits involved in mitotic bookmarking and transmission of the transcriptional memory in cell cycle stages. Knowing the expression dynamics of SWI/SNF subunits driving gene bookmarking in the M-phase of lineage stem cells and cancer cells can lend therapeutic information.For future work, it would be interesting to probe the plausible contribution of SMARCC1 (BAF155) in mitotic bookmarking as it was observed bound to mitotic chromatin, although at a mild intensity."} +{"text": "Misoprostol is a prostaglandin E1 (PGE1) analogue that has been on the World Health Organization (WHO) List of Essential Medicines since 2005.Brazil has one of the most restrictive regulations in the world related to the use of misoprostol establishing it is exclusively for hospital use with special control, and sale, purchase and advertising prohibited by law.Misoprostol is currently the reference drug for pharmacological treatment in cases of induced abortion, both in the first trimester of pregnancy and at more advanced gestational ages.Misoprostol is an effective medication for cervical ripening and labor induction.Misoprostol is an essential drug for the management of postpartum hemorrhage.The use of misoprostol is recommended for the following situations: legal abortion, uterine evacuation due to embryonic or fetal death, cervical ripening before labor induction (uterine cervix maturation), labor induction and management of postpartum hemorrhage.Misoprostol 800 mcg vaginally (four 200 mcg pills) is recommended for uterine evacuation in pregnancy loss up to 13 weeks.In cervical preparation for surgical abortion at less than 13 weeks of pregnancy, the use of misoprostol 400 mcg vaginally 3-4 hours before the procedure is recommended.The use of misoprostol alone according to the gestational age for uterine evacuation is recommended for termination of pregnancy in legal abortion.The use of vaginal misoprostol according to the gestational age is recommended for uterine evacuation in case of fetal death: at 13-26 weeks, 200 mcg every 4-6 hours; at 27-28 weeks, 100 mcg every 4-6 hours; and over 28 weeks, 25 mcg every six hours.The use of misoprostol at an initial dose of 25 mcg vaginally every 4-6 hours is recommended for cervical ripening and induction of labor with a live fetus in pregnancies over 26 weeks.The use of misoprostol for cervical ripening and induction of labor with a live fetus is not recommended in women with a previous cesarean section due to the greater risk of uterine rupture.Misoprostol is a safe and effective option for women with premature rupture of membranes and unfavorable uterine cervix, as long as they do not have contraindications for taking the medication, for example, previous cesarean section.Rectal misoprostol 800 mcg is recommended as part of the drug treatment of postpartum hemorrhage.In Brazil, misoprostol should be made available to all health services at all levels of care, and it is desirable that outpatient use be allowed, when indicated.Misoprostol is a synthetic analogue of prostaglandin E1 (PGE1) with gastric secretion inhibitory and mucosal protection properties through the production of bicarbonate and mucus. It was first approved to be used to protect the stomach mucosa in patients using non-steroidal anti-inflammatory drugs.Misoprostol is a synthetic analogue of PGE1. It is metabolized in the liver, deesterified and becomes the active metabolite, misoprostol acid. It has the ability to bind to uterine smooth muscle cells, increasing the strength and frequency of uterine contractions.Although other prostaglandins can cause myocardial infarction and bronchospasm, misoprostol is not associated with these effects. Toxic doses have not been well established and cumulative doses of up to 2,200 mcg in 12 hours are well tolerated without significant adverse effects.The Food and Drug Administration (FDA) classifies misoprostol as a category X drug in the first and second trimesters of pregnancy. Animal studies have shown a significant reduction in fertility with the use of high doses (6.25 to 625 times the maximum human therapeutic dose). In pregnant rabbits, doses of 300 to 1,500 mcg/kg of misoprostol on days 7-19 of embryogenesis have been associated with teratogenic effects.Misoprostol is used for uterine evacuation in first trimester pregnancy loss. On ultrasound examination, pregnancy loss can be characterized by the following aspects: presence of gestational sac without yolk sac or embryo and with mean diameter \u2265 25 mm; embryo with crown-rump length greater than or equal to 7 mm without cardiac activity; no embryo with a heartbeat two weeks after an examination demonstrating an empty gestational sac or no embryo with a heartbeat at 11 or more days after an examination demonstrating a gestational sac with yolk sac. In these situations, three approaches are possible: expectant management, mechanical uterine evacuation, or pharmacological evacuation.Brazil has one of the most restrictive regulations related to induced abortion - induced abortion is only legally permitted in cases of pregnancy resulting from rape, risk to the woman's life and fetal anencephaly \u2013 and to the use of misoprostol in the world. In a study of countries in Africa, Asia and Latin America, Brazil was close only to Vietnam among those with greater restrictions on access to medical abortion in the world.In cervical preparation prior to surgical abortion in pregnancies over 12-14 weeks, the use of misoprostol 400 mcg 2-3 hours before surgical treatment is routinely recommended.The use of misoprostol on an outpatient basis is considered effective and safe for the treatment of induced abortion, especially in the first 12 weeks of pregnancy. The use of misoprostol during this period has minimal adverse effects, such as diarrhea, vomiting, nausea and fever, which can be easily treated by professionals outside the hospital setting.When the diagnosis of fetal death is established, the health professional assisting this pregnant woman and her family must always be able to answer the posed questions with empathy and embracement, even if there are no answers to all. A systematic review including 14 controlled and randomized studies that evaluated the use of misoprostol in fetal death in the second and third trimesters found 100% effectiveness in uterine evacuation within 48 hours.In cases of fetal death after more than 24 weeks, labor induction depends on the conditions of cervical maturation. In patients with a favorable cervix (Bishop index \u2265 6), labor induction can be started with oxytocin without the use of misoprostol for previous cervical ripening. In patients with an unfavorable cervix and without previous uterine scar, misoprostol is the agent of choice for preparing the cervix and inducing labor.25-26 weeks: misoprostol 400 mcg vaginally or sublingually every 4-6 hours;27-28 weeks: misoprostol 100 mcg vaginally or sublingually every 4-6 hours;Over 28 weeks: misoprostol 25 mcg vaginally every six hours.In patients with previous segmental scarring and unfavorable cervix at 24-28 weeks, cervical preparation can be performed with a mechanical method followed by the use of oxytocin. The use of misoprostol seems to be an acceptable alternative at this gestational age, since the risk of uterine rupture is low. In a review study in which misoprostol was used at this gestational age, the risk of uterine rupture was 0.28% (95% CI: 0.08-1.00) in patients with a previous cesarean section versus 0.04% (95% CI: 0.01-0.20) in patients without a previous cesarean section.In the labor induction process, when the situation of the uterine cervix is unfavorable, a maturation process is recommended to shorten the duration of induction and increase the chance of vaginal delivery. When the Bishop score is less than 6, the cervix is generally considered unfavorable, and mechanical and/or pharmacological methods can be used in this process.Women planning a vaginal birth after a previous caesarean section may need labor induction. There are two concerns: reduced chances of vaginal birth after caesarean section (VBAC) and increased risk of uterine rupture. Having a previous vaginal delivery and a favorable cervix are the main predictors of induction resulting in VBAC.No previous vaginal delivery \u2013 for example, in a study, the risks of rupture during TOLAC-induced in women without a previous vaginal delivery versus a previous vaginal delivery were 1.5% and 0.6%, respectively;Use of prostaglandins \u2013 induction with prostaglandins appears to be associated with a greater risk of uterine rupture than induction with oxytocin or cervical ripening with mechanical methods followed by administration of oxytocin.Risk of rupture with prostaglandin use\u2013 Data from large randomized trials and from good quality observational studies on the effects of prostaglandins alone or in combination with other agents for cervical ripening in TOLAC are not available. Much data on prostaglandin use in women with a previous caesarean section has been derived from observational studies in which misoprostol (PGE1) was used. Reports on the use of other prostaglandins, such as prostaglandin E2, are limited by their small size, the co-administration of other agents and the lack of stratification by previous vaginal delivery.Unspecified prostaglandin\u2013 Concern over the use of prostaglandins arose following the publication of a large population-based retrospective cohort study that analyzed data from 20,095 primiparous women who delivered after a single previous cesarean section.Repeat cesarean sections without labor: 1.6 ruptures per 1,000 planned repeat cesareans;Spontaneous labor: 5.2 ruptures per 1,000 spontaneous deliveries;Induced labor (without prostaglandins): 7.7 ruptures per 1,000 labors induced without the use of prostaglandins;Induced labor (with prostaglandins): 24.5 ruptures per 1,000 labors induced using prostaglandins. Compared to repeat cesarean delivery, the relative risk of rupture with the use of prostaglandins was 15.6 (95% CI: 8.1-30.0).However, despite the very large number of cases, the information in this study is from a database and individual reviews of medical records were not performed to check other medications administered. The risk of uterine rupture reported in this retrospective study was lower in another large prospective study.American College of Obstetricians and Gynecologists (ACOG \u2013United States)Society of Obstetricians and Gynecologists of Canada (SOGC \u2013 Canada)National Institute for Health and Care Excellence (United Kingdom)In conclusion, the use of misoprostol in women with previous cesarean is not recommended given the higher risk of uterine rupture. Note that mechanical methods are available, effective and safe.Premature rupture of membranes (PROM) is one of the most common complications of term and preterm pregnancies, but there is a gap in knowledge about how management affects the cesarean rate. As gestational age at delivery is the critical factor influencing perinatal outcome, expectant management is generally adopted when far from term. In PROM at term, the risk of maternal and fetal infectious morbidity increases with longer duration of membrane rupture. Therefore, expectant management should be brief, with instructions for induction of labor.Postpartum hemorrhage affects around 2% of all patients, and in only 25% of cases the risk factors are pronounced. The obstetrician must perform prophylaxis in 100% of cases and be aware of the occurrence of PPH, even if drug prophylaxis is performed. There is strong evidence that the association of uterotonics prescribed in the immediate postoperative period of childbirth reduces blood loss greater than 500 mL: ergometrine plus oxytocin and misoprostol plus oxytocin and reduces the need for blood products .Oxytocin:In post-vaginal delivery: single dose of 10 IU intramuscularly right after birth;In cesarean section: 5 IU in slow intravenous infusion in three minutes and maintenance solution ;Misoprostol: single dose of 600 mcg rectally;Ergometrine: single dose of 0.2 mg intramuscularly.For the drug treatment of PPH, the use of misoprostol 800 mcg rectally is recommended. It is important to remember that since the onset of action of rectal misoprostol is slower than that of other uterotonics, it should be used as an adjuvant to treatment with oxytocin. Misoprostol should not be used in isolation, maintaining uterine massage until the onset of its effect, which may take 15-20 minutes. Always consider the use of tranexamic acid 1 g intravenously over 10 minutes, with the possibility of repeating the 1 g dose in 30 minutes if bleeding persists.Circular letter number 182/2021 of the Office of the President of the Brazilian Federal Council of Medicine,In obstetric practice, misoprostol has been widely used in legal abortion, uterine emptying due to embryonic or fetal death, cervical ripening and labor induction, and management of PPH. Contrary to the accumulated scientific evidence, Brazil has one of the most restrictive regulations in the world related to the use of misoprostol. The great difficulty in acquiring, storing and dispensing the medication imposed by Ordinance No. 344/1998 of Anvisa, still in force, contributes to denying the right to safer outpatient treatments for women who need it. These restrictions also hinder the availability of this medication, essential and mandatory, in obstetric care services.National Commission Specialized in Childbirth, Puerperium and Abortion Care of

that focused on the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination, and their relation with depression and post-traumatic stress disorder (PTSD). The overall research aim was to examine the relationship between these transdiagnostic factors and their relation with depression and PTSD symptoms. The systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Out of the 768 articles initially identified, 55 met the inclusion criteria for the current review. The results determined that intolerance of uncertainty is indirectly related to depression and PTSD symptoms, mainly through other factors including emotion dysregulation and rumination. Additionally, emotional dysregulation is a significant predictor of both depression and PTSD symptoms. Rumination is a robust factor related to depression and PTSD symptoms, this relationship was significant in cross-sectional and longitudinal studies. This review provides evidence on the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination in the relationship with depression and PTSD symptoms. Depressive, anxiety, and substance use disorders are among the leading contributors to the global disease burden lack of awareness, understanding, and acceptance of emotions; (b) the inability to control behaviors when experiencing emotional distress; (c) lack of access to situationally appropriate strategies to modulate the duration and/or intensity of emotional responses to meet individual goals and situational demands; and (d) unwillingness or reluctance to experience emotional distress as part of seeking meaningful activities in life guidelines Empirical quantitative research reports published in a peer reviewed journal (2) Written in English or Spanish language, (3) Outcome measures related to depression or PTSD symptoms or diagnosis. Studies were excluded if the following criteria was met: (1) No depression or PTSD outcome measure, (2) No rumination, intolerance of uncertainty or emotional dysregulation measure, (3) Not depression PTSD comorbidity, (4) Children or adolescent sample, (5) Insufficient or inappropriate data reported , specifically USA (21 studies), and Canada (3 studies). Followed by 25.5% from European countries, 16.4% from Asia including China (4 studies), Japan (1 study), India and Iran (2 studies each), 7.2% from Oceania particularly, Australia (4 studies), and 7.2% from South America including Argentina (2 studies), Colombia and Chile (1 study each). Community-based studies were the most frequent type (39%), followed by undergraduate student sample (27.1%), clinical sample (18.6%), and trauma exposed sample (15.3%). Most of the studies were cross-sectional (66.1%), followed by longitudinal (28.6%) and a minority were experimental (5.4%).Eleven studies examined the relation between intolerance of uncertainty and depression symptomatology. Empirical evidence indicates that intolerance of uncertainty is a significant predictor of depression symptoms, even when anxiety symptoms where accounted for (Barry et al., Six studies that examined the relation between intolerance of uncertainty and PTSD symptoms. This evidence indicates that intolerance of uncertainty is a significant predictor of PTSD symptoms. These result remained significant even after covarying for other PTSD risk factors including: rumination, neuroticism, and worry (Boelen et al., When the relation between intolerance of uncertainty and PTSD symptoms DSM-V clusters was examined, there was a significant association to the avoidance, hyperarousal and emotional numbing symptom clusters (Oglesby et al., We identified 8 studies that assessed the relation between emotion dysregulation and depression symptoms. Results indicated that emotion dysregulation was positively associated with depressive symptoms, even when controlling for baseline mindfulness (Diehl et al., Seven studies assessed the relation between emotional dysregulation and PTSD symptoms. Longitudinal assessments found that emotional dysregulation was significantly associated with the probability of developing PTSD symptoms 4\u00a0months later (Fujisato et al., Thirteen studies examined the relation between rumination and depression symptoms. Results from longitudinal associations indicated that rumination predicts depressive symptoms and that depressive symptoms predict rumination at 4-year follow-up (Whisman et al., Ten studies examined the relation between rumination and PTSD. Repetitive and anticipatory rumination moderated the relationship between PTSD and MDD symptoms (Roley et al., The current systematic review sought to identify quantitative empirical studies that focused on the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination, and their relation with depression and/or PTSD. This review identified 55 studies that reported the association between the transdiagnostic factors of interest in depression and PTSD symptoms.Intolerance of uncertainty was a consistent significant predictor for both depression and PTSD symptoms, as suggested by other authors (McEvoy et al., Emotional dysregulation has been found to relate to depression as well as many other psychiatric symptoms including PTSD (Aldao et al., Rumination is an important factor related to the maintenance and exacerbation of depression and PTSD symptoms (Olatunji et al., This systematic review had a number of limitations that should be taken into account when interpreting the results and addressed in future research. First, even though studies in Spanish were included in an attempt broaden the scope, the majority of the studies were conducted in North American and European countries. Furthermore, taking into consideration the evidence that culture may play a significant role in the manifestation of psychopathology Rathod, , the resThis review provides evidence that the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination are consistent significant predictors for both depression and PTSD symptoms. Particularly, intolerance of uncertainty is indirectly related to depression and PTSD symptoms through other factors including emotion dysregulation and rumination. Meanwhile, emotional dysregulation is a significant predictor of both depression and PTSD symptoms. Rumination is a robust factor related to depression and PTSD symptoms, this relationship was significant in cross-sectional and longitudinal studies. Both emotional dysregulation and rumination can mediate the relationship between several risk factors including intolerance of uncertainty and depression and PTSD symptoms. This study provides insight into understanding these factors in the onset and maintenance of depression and PTSD symptomatology. Consequently, contributing to the evidence that allows the development of theoretical and empirically supported transdiagnostic models. Which may ultimately promote the development of cost-effective treatments that targets underlaying mechanism or factors, thus promoting preventative alternatives for multiple disorders."} +{"text": "Motivation is an important factor in therapy and potentially even more so in an online setting. Earlier research shows that more autonomously motivated patients have better outcomes and completion rates than more controlled motivated patients\u00b4. However, little is known about how motivation type influences treatment effect in an online setting and in patients with binge eating disorder specifically.This study set out to investigate how motivation type as per the Self-Determination Theory would affect treatment adherence and effect in a sample of 148 patients, undergoing an Internet-based Cognitive Behavioral Therapy (iCBT) for BED.The study was mixed-methods. A sample of 148 patients gave two written qualitative statements regarding their motivation for seeking treatment and reasons for choosing online therapyThe statements were transformed into quantitative units via the condensation method. The themes were categorized according to the model by Ryan and Deci based on level of autonomy and perceived locus of causality.This was compared with completion rate and outcomes on eating disorder symptomatology. Completion was designated into three groups. Low adherers - less than six sessions (n=54), high adherers \u2013 between 7 and 10 sessions (n =56) and full adherers - 10 session plus follow up (n=37).The effect of the treatment was measured via the Eating Disorder Examination Questionnaire (EDEQ) and Binge Eating Disorder Questionnaire (BEDQ).Perceived locus of causality and level of autonomy, did not affect level of adherence or outcome of treatment in either setting. This unexpected result may suggest that internet-based therapy is less dependent on motivation types, when comparing with face-to-face treatment.None Declared"} +{"text": "Correction to: Japanese Journal of Radiology (2021) 39:84\u201392 10.1007/s11604-020-01040-1In the original publication, the last sentence under heading Patients in section Materials and methods should read as:All patients gave written informed consent for the procedure.The revised Ethical approval statement should read as:Ethical approval All procedures performed in these studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki Declaration and its later amendments.

Anticoagulant prophylaxis is necessary to reduce the risk of deep vein thrombosis (DVT), which may progress to symptomatic outcomes such as pulmonary embolism (PE). Prophylaxis and treatment of patients with symptomatic VTE occurs in 2 phases. Initial therapy focuses on rapid achievement of effective anticoagulation and usually involves subcutaneous low-molecular-weight heparin.

Based on the support of the young sections of Italian Association of Medical Oncology (AIOM), Italian Association of Radiotherapy and Clinical Oncology (AIRO) and Italian Society of Surgical Oncology (SICO) merged into the NutriOnc Research Group, we performed a multidisciplinary national survey with the aim to define the awareness of nutritional issues among healthcare professionals delivering anticancer care. The questionnaire was organized in four sections, as follows: Knowledge and practices regarding Nutritional Management of cancer patients; Timing of screening and assessment of Nutritional Status; Nutritional Treatment and prescription criteria; Immunonutrition and educational topics. The modules focused on esophagogastric, hepato-bilio-pancreatic and colorectal malignancies. Overall, 215 physicians completed the survey. As regards the management of Nutritional Status of cancer patients, many responders adopted the ERAS program (49.3%), while a consistent number of professionals did not follow a specific validated nutritional care protocol (41.8%), mainly due to lack of educational courses (14.5%) and financial support (15.3%). Nearly all the included institutions had a multidisciplinary team (92%) to finalize the treatment decision-making. Cancer patients routinely underwent nutritional screening according to 57.2% of interviewed physicians. The timing of nutritional assessment was at diagnosis (37.8%), before surgery (25.9%), after surgery (16.7%), before radiochemotherapy (13.5%) and after radiochemotherapy (7%). Most of the responders reported that nutritional status was assessed throughout the duration of cancer treatments (55.6%). An important gap between current delivery and need of nutritional assessment persists. The development of specific and defined care protocols and the adherence to these tools may be the key to improving nutritional support management in clinical practice."} +{"text": "Sussex cattle breed is characterized by their distinctive solid red coat colour and white tail switch. Sussex cattle are known for being easy to handle and manage, making them an ideal choice for cattle farmers. The phenotypic characterization of this cattle breed in South Africa is unknown. Hence, the objective of this study was to characterize the morphological structure, phenotypic and body indices traits of Sussex cattle in South Africa at Huntersvlei farm, Frere State province of South Africa. One hundred and one weaners (n = 101) between 6 and 8 months old and fifty yearlings between 12 and 15 months old were used in this study. Body weight at weaning, yearling and linear body measurements such as head length (HL), head width (HW), ear length (EL), ear width (EW), sternum height (SH), withers height (WH), heart girth (HG), hip height (HH), body length (BL), rump length (RL), and rump width (RW) were measured. Moreover, the animals were assessed for coat colour and horn presence. Descriptive statistics, Pearson\u2019s correlation and Principal Component Analysis (PCA) were used to describe the Sussex cattle breed. The results indicated that male Sussex cattle had highly significant (p < 0.01) mean numeric values for the BW and morphometric traits. The results further showed that Sussex cattle had highly significant (p < 0.01) increase for the BW and morphometric traits as age advances in all sexes. Interaction effect of sex and age showed a highly significant (p < 0.01) effect with BW and measured morphometric traits, while moderately significant (p < 0.05) with EW. Male Sussex cattle showed highly significant (p < 0.01) higher mean numeric values for the body index (BI), length index (LI) and compact index (CI) indices. While female Sussex animals showed highly significant (p < 0.01) mean numeric values for area index (AI) and proportionality (PR). Body weight showed a positive highly significant (p < 0.01) correlation with the measured morphometric traits except for the moderate significant (p < 0.05) correlation with EL. Coat colour traits ranged from 15 (9.93%), 103 (68.21%) to 33 (21.85%) for light, moderate and dark colours, respectively. While horn presence traits ranged from 48 (31.79%), 42 (27.81%) to 61 (40.40%) for polled, scur and horned respectively. The PCA results extracted only two components in both sexes of the animals. The morphological variations obtained in this study could be complemented by performance data and molecular markers of single nucleotide polymorphism (SNP) to guide the overall breed characterization, conservation and development of appropriate breeding and selection strategies. Livestock plays an important role in the social, economic and cultural stability of rural households in many parts of the world . MASA 22 reporteThe experimental procedures were conducted following the University of South Africa (UNISA) Ethics code for the use of live animals in research, ethics reference number: 2022/CAES_AREC/171.This study was conducted at Huntersvlei farm also known as Rhys Evans Group (RE) in the Free State Province, South Africa. The farm is situated in Viljoenskroon, Fezile Dabi municipality; the site, temperatures, latitudes, longitude, and rainfall of the study area similar as described by Bila . HuntersAll the animals used in the study were exposed to a traditional management grazing system which allows animals to freely graze in the camps during the day and afternoon. Fresh clean water was always available in the camps. Animals received a routine inspection and dipping for herd health management purposes. The linear body measurements were taken while the animal was in a standing position with head raised up and weighed on all four feet. A functional handling facility with a crowding pen, working crush and head clamp was used for handling the animals to minimize movement during the measuring process.Morphometric traits and live body weight at two different stages were taken. The first stage was at weaning age in one hundred and one (n = 101) South African Sussex weaner animals between 6 and 8 months old. Second stage yearling age is 50 South African Sussex yearling animals are between 12 and 15 months old. The animals used in the study at weaning age were between six to fifteen months old. The live body weight at the two stages was measured using a balance weighing scale whereas linear body measurements were measured using a measuring tape calibrated in centimetres (cm). The body weight at weaning, yearling and morphometric traits, namely head length (HL), head width (HW), ear length (EL), ear width (EW), sternum height (SH), withers height (WH), heart girth (HG), hip height (HH), body length (BL), rump length (RL), and rump width (RW) were measured following the guideline defined by Lomillos and Alonso , Tyasi eTo prevent individual variations in measurements, only one individual was taking the body weight and morphometric traits. The horn presence was assessed using three point scale following the guidelines reported by Grobler et al. . Moreove2) test was used to find the significant difference on qualitative traits. Procedure of correlation (PROC CORR) was used to determine Pearson\u2019s correlation matrix. These analyses were then followed by a principal component analysis (PCA) to reduce the dimensionality of the morphometric data using the procedure of principal component (PROC PRINCOMP and PROC FACTOR). Furthermore, to examine the morphometric traits and body indices that have the most discriminating power the stepwise discriminant analysis was applied using the STEPDISC procedure (PROC STEPDISC). The significant difference was observed at P<0.05 and highly significant at P<0.01.The Statistical Analysis System version The overall summary of the collected data discoverMeans and standard deviation for the sex effect on body weight and morphometric traits is given in The overall summary of the collected data discoverMeans and standard deviation for the overall sex effect on body indices is given in In females, the BI showed a positive highly significant (p < 0.01) correlation with LI, while moderately significant (p < 0.05) correlated with PI and insignificant (p > 0.05) correlated with CI .

Phenotypic variation of local animal resources shows a genetic diversity that may be worth conserving for future uses while better understanding of the external features assists to facilitate the implementation of conservation policies intended to ensure local resources survival . FirstlyFurthermore, the results of the study showed that the coat colour both in male and female populations had a highly significant effect with males showing a maximum incident of dark coat colour while females showing a maximum incident moderate coat colour. On the other hand, the horn presence showed a significant effect amongst the sexes with males showing a maximum occurrence of horn presence and females showing a maximum occurrence of polledness. Bila and Tyasi showed tThe importance of morphological characterization of cattle breed\u2019s genetic resources cannot be emphasized. The present study is based on morphometric and certain phenotypic traits of Sussex cattle at Huntersvlei farm in South Africa. The study findings displayed the morphological and phenotypic variations between ages and genders of the Sussex cattle breed at Huntersvlei farm. It was found that the Sussex cattle breed in the study area have developed some diverse phenotypic traits such polled, scur and horns. Moreover, the Sussex cattle at Huntersvlei farm showed that the male animals had a much darker red brown colour in comparison to female animals. The correlation results shown that in male BW had highest positive association with HH, BL and WH and hence can be used as markers to predict BW using regression equations. The extracted principal components from different morphometric traits symbolize the general body size and shape of the Sussex cattle population at Huntersvlei farm. Stepwise canonical discriminant analysis showed that head width, head length, hip height, sternum height, heart girth and rump width are the suitable discriminating morphometric traits in the Sussex cattle breed. Furthermore, an investigation on the molecular characterization using molecular markers SNP will complement the results obtained from morphometric variation. Lastly these findings might be helpful in breed characterization, conservation and developing breeding and selection strategies.S1 FileIt is an Excel file with variables fully explained in column P and Q of the sheet.(XLSX)Click here for additional data file.S2 FileIt is an Excel file with variables fully explained in column E, F and G of the sheet.(XLSX)Click here for additional data file."} +{"text": "Based on studies showing the use of autologous skin cell suspensions (ASCS) leads to burn wound closure with significantly smaller amounts of harvested donor skin, the Food and Drug Administration approved the first ASCS for the reconstruction of thermal injuries in September, 2018.

It is included on chest radiographs of dogs and cats, but little information is available for veterinarians on what abnormalities or diseases affect the chest bone in companion animals. We reassessed chest radiographs of dogs and cats taken in our hospital over a 2 year period to describe these changes. We found that abnormalities of the chest bone were visible in 24% of dogs and 29% of cats, with the most common abnormality being age-related degeneration. Most of the abnormalities noted were of minor clinical importance, but in some animals, conditions that could be painful or otherwise affect well-being were seen.Evaluation of the sternum is part of the routine examination of small animal thoracic radiographs. However, descriptions on frequency and type of abnormalities are lacking. This retrospective observational study aimed to describe abnormal radiographic findings of the sternum in a cross-section of client-owned dogs and cats undergoing thoracic radiography between 1 January 2019 and 1 January 2021 for reasons unrelated to diseases of the sternum. The study population consisted of 777 dogs and 183 cats . Sternal abnormalities were observed in 189/777 (24%) dogs and 53/183 (29%) cats, mostly around the intersternebral cartilages, accounting for 32/80 (40%) dogs and 20/35 (57%) cats. This was followed by an abnormal number of sternal segments . Pectus excavatum was observed in 6/777 (0.8%) dogs and 6/183 (3%) cats, and pectus carinatum in 18/777 (2%) dogs and 2/183 (1%) cats. Post-traumatic changes, such as subluxation, were observed in nine dogs (1.1%) and three cats (1.6%). Presumed prostatic carcinoma metastasis and malignant lymphoma were observed in two dogs (0.2%). Incidental radiographic sternal abnormalities are common in cats and dogs but mostly of unknown clinical relevance. An evaluation of the sternum is part of the routine examination of small animal thoracic radiographs, as it forms the ventral contour of the thoracic cavity. The sternum contributes to the bony protection of the intra-thoracic cardiopulmonary structures, as well as to the stability and breathing motion of the thorax.manubrium sterni), is wider and longer than the other sternal segments. The manubrium of the sternum is the point of insertion of the sternocephalicus muscle and has lateral shelves of bone accommodating the attachment of the costal cartilages of the first pair of ribs. The body of the sternum (corpus sterni) consists of six rectangular to cylindrical-shaped sternebrae. The most caudal last sternebra, or xiphoid process (processus xiphoideus), is flat and long, occasionally with a foramen in its caudal half. The xiphoid process is prolonged caudally by the xiphoid cartilage (cartilago xiphoidea), which supports the cranial part of the ventral abdominal wall and from which the linea alba extends caudally to the symphysis pelvis. The individual sternebrae are connected by intersternebral cartilages, forming cartilaginous joints , and the sternum is covered on the ventral and dorsal surface by thickened periosteum, forming the sternal membrane (membrana sterni). Whilst the costal cartilages of the first pair of ribs articulate directly with the manubrium of the sternum, the costal cartilages of the second to seventh ribs articulate with the consecutive intersternebral cartilages between the individual sternal segments, and both the costal cartilages of the eighth and ninth rib pairs articulate with the intersternebral cartilage between the seventh sternebra and the xiphoid process. The first eight paired sternocostal joints are synovial joints, but no synovial joint was found at the ninth sternocostal articulation The costal cartilages of the last four pairs of ribs do not directly articulate with the sternum but connect via the costal arch or are floating ribs, and these ribs are therefore considered asternal ribs ) if normally distributed or as median (range) if the distribution was skewed.

Marked degenerative changes, such as narrowing of the intersternebral cartilage space (n = 13), vacuum phenomenon (n = 13), and subluxation (n = 5), were mainly observed in the mid-section of the sternum, between the 3rd and 4th and 4th and 5th sternebrae (n = 16). The mean age of dogs with degenerative changes was significantly higher than the mean age of dogs without these changes .Abnormalities were most frequently observed in the area of the intersternebral cartilages in dogs . Less than eight sternal segments were observed 46 dogs (6%): seven sternebrae were visible in 40 dogs, six sternebrae in four dogs, and three and four sternebrae in one dog each. The latter resulted in morphologically abnormal short sternum (n = 5) or four (n = 2) sternebrae. Three dogs with lower number of sternebrae showed border effacement of the ventral thoracic diaphragmatic surface and the caudal ventral cardiac silhouette due to cranial excursion of the diaphragm, but none of these animals had evidence of peritoneopericardial herniation. Supernumerary sternal segments were observed in 16 dogs (2%), affecting predominantly medium and large breed dogs.

Concurrent gas opacity in the intersternebral cartilage space or associated subluxation of sternebrae was not observed in any of the cats with signs of degenerative changes of the intersternebral cartilages.Degenerative changes, consistent of mineralization of the sternal cartilages or formation of bony spurs, were observed in 15 cats (8%). Cats with degenerative changes were significantly older than those without or sixth and seventh sternebrae (n = 5). The other nine cats with seven sternebrae had an absence of one sternal segment. One Domestic Shorthair had six individual sternebrae, caused by complete fusion of the fourth and fifth sternebrae and the absence of one sternal segment , of which seven cats had nine sternebrae. Nineteen cats had seven individual sternal segments, which, in ten cats was caused by complete fusion of the first and second sternebrae ( segment .Pectus excavatum was observed in six cats (3%), and the severity was considered mild in four cats and moderate and severe in one cat each .

Other aThe sternum develops from the fusion of bilateral mesodermal bars which unite from day 25 of gestation in dogs and day 28 of gestation in cats, starting cranially at the manubrium of the sternum and ending caudally at the xiphoid process ,24. OssiAs in previous reports, pectus excavatum mostly affected the caudal sternum in dogs in our study population, which is the typical form of pectus excavatum . Komsta In agreement with a previous publication by Hassan and colleagues (2018), we observed pectus carinatum predominantly in small breed dogs, except for in one English Springer Spaniel . In thatAlthough neoplastic disease was the most common indication for thoracic radiography in dogs, only two cases presented with radiographic aggressive bone lesions affecting the sternum. One dog diagnosed with malignant lymphoma presented with pathological fractures of multiple sternebrae, the other dog was diagnosed with prostatic carcinoma and had an aggressive bone lesion affecting the second and third sternebrae. However, the sternal lesions were not biopsied in these dogs and therefore it remains unknown if these aggressive bone lesions indeed were caused by neoplastic disease. Skeletal involvement affecting the spine has been described in canine multicentric lymphoma ,30, but synchondroses sternales, mostly consistent of mineralization of the sternal cartilages or formation of bony spurs, was the most common finding in our study, with a prevalence of 14% in dogs and 8% in cats. In 13 of the dogs affected, gas opacity was observed in between the sternebrae on the left lateral view radiograph. Gas accumulation within synovial joints and intervertebral disc spaces is termed vacuum phenomenon. This gas consists of 90\u201392% nitrogen and its presence has been associated with intervertebral disc degeneration in dogs [synchondrosis sternalis in dogs, similar to the above-mentioned association between vacuum phenomenon in the intervertebral disc space and intervertebral disc degeneration in dogs [Age-related degeneration of the in dogs ,36,37. T in dogs and, in in dogs . In our Sternal dislocation is infrequently reported in veterinary literature and is most often considered to be of traumatic origin ,16,17. BOur study had several limitations. First, the retrospective design prohibits adequate correlation between radiographic findings and clinical signs. For example, it cannot be reliably determined if sternal dislocation in dogs with severe intersternebral cartilage degeneration was associated with pain or other clinical signs, because no specific history and physical examination addressing these findings were performed in these cases. Secondly, the large variety in breeds in combination with the relatively low number of cases for each disorder impedes drawing firm conclusions on any breed predispositions. Thirdly, the use of radiography instead of a cross-sectional technique such as computed tomography results in a lower sensitivity for detection of abnormalities because of the inferior contrast resolution and problems of superimposition inherent to radiography. Moreover, computed tomography would allow a better representation of the anatomy. For instance, computed tomography was reported to be useful for evaluation of thoracic asymmetry and sternal torsion in cats with pectus excavatum, which cannot be done with radiography . In addiSternal abnormalities are common incidental findings on thoracic radiographs of companion animals and were observed on thoracic radiographs of 24% of dogs and of 29% of cats in our study population. Clinically relevant abnormalities, such as severe degeneration of the intersternebral cartilage space, dislocation, or aggressive bone lesions, were only recognized in few cases, whilst most animals showed abnormalities that were unlikely to cause clinical complaints."} +{"text": "To determine the extent to which primary care physicians have been willing to incorporate computerized protocols and clinical information systems into their practices.A survey was fielded to both primary care and non hospital-based specialty group practices of five physicians or more.The types of these technologies in use and the degree to which the physicians themselves were active users.Findings (n=197 or a 38% response rate) are presented grouped by three stages of software application adoption: (1) transaction; (2) decision support; and (3) expert systems or simulation of human thought. Transaction systems, particularly applications that support practice administration such as registration, billing, and scheduling, have the highest percentage of adoption (82% to 97%). Expert systems are uncommon (3% to 6%), with slightly higher penetration of telephone triage (such as \"ask-a-nurse\") and prevention reminders applications . Within group practices, physician \"hands-on\" use of systems is low for viewing (28%), and even lower for entering patient information (6% to 8%).Emerging knowledge technologies such as medical decision support or expert systems are not widely accepted and may even threaten traditional physician domains of expertise.

Total numbers and mean diameters of cavitary and solid nodules in each thorax computed tomography (CT) have been determined and followed up by two experienced pulmonary physicians. Moreover, changes in treatment after the development of the CPN lesions and characteristics of cavitary nodules were collected.Eleven patients with CPN lesions were reported. At the time of CPN diagnosis, more patients were taking leflunomide than methotrexate (81% vs 19%). Half of the patients were receiving biologic therapy and only 18% were taking anti-TNF drugs. After a median of 24 (3\u201365) months of follow-up, the regression of CPN lesions was determined in 45% (5/11) of patients. Four of these 5 (80%) patients were switched to a treatment regimen without leflunomide and three of them to nonanti-TNF biologic treatment or targeted synthetic DMARDs .CPN lesions seen in RA patients are often pulmonary manifestations of the underlying disease; however, one must rule out malignancies or infections.

Pulmonary disease, which is a major source of morbidity and mortality in RA, manifests most commonly as interstitial lung disease (ILD), airways disease, rheumatoid nodules (RN), and pleural effusions .The prevalence of rheumatoid pulmonary nodules, also called necrobiotic nodules, ranges from less than 0.4% in radiological studies to 32% in lung biopsies of patients with RA [Nodules usually present a diagnostic challenge rather than therapeutic. Nodules in RA patients should be evaluated similarly to those in any other patient presenting with solitary or multiple pulmonary nodules, as nodules may reflect the presence of infection, malignancy, or other inflammatory diseases. Biologic drugs are now widely used for treating RA. Various side effects, mainly infection, have been described with these drugs. The efficacy of these agents for the treatment of pulmonary involvement of disease has not been specifically evaluated in large placebo-controlled randomized trials.We report characteristics of 11 patients with RA developing cavitary pulmonary nodular (CPN) lesions under disease-modifying antirheumatic drugs (DMARDs) and follow-up of cavitary nodules and their outcome with the treatment were reported.RA patients who presented with CPN lesions during follow-up between September 2009 and April 2019 in rheumatology outpatient clinic were recruited retrospectively in this case series analysis. Diagnosis of the CPN lesions was made with computed tomography (CT) scan and indication for imaging of these patients were constitutional/respiratory symptoms or any abnormality at routine annual conventional radiography during biological treatment. Characteristics of the patients, positron emission tomography (PET), and biopsy (if available) findings were collected from patient reports. Patients without biopsy were the ones who did not accept biopsy or who had contraindication for biopsy (with cardiac failure and arrhythmia treated by the cardiac pacemaker). In addition to these, changes in treatment after development of the CPN lesion and characteristic of cavitary nodules were collected. Outcome assessment focused mainly on the number and characteristics of all nodules with the modification of treatments, but we also evaluated cavitary nodules separately. Total numbers and mean diameters of cavitary and solid nodules in each CT have been determined with the agreed decision of two experienced pulmonary physicians, who were aware of the clinical data of the patients. An increase in total nodule count or new cavitation of a solid nodule at CT was accepted as a progression of the lesion. It is also accepted as a progression of the lesion if there is a 20% or more increase of mean nodule size even though total and cavitary nodule count is stable. A decrease in total or cavitary nodule count and a 30% or more decrease in mean nodule size is accepted as regression of the lesion.The study was approved by the local clinical research ethics committee (reference number: 09.2019.592)Before initiation of biologic drugs (except rituximab), each patient was screened for tuberculosis and underwent conventional radiography, clinical pulmonary examination, and ppd/QuantiFERON test, and tuberculosis prophylaxis (9 months of isoniazid) was given to 5 of them as the results of these tests.Two patients received antituberculosis treatment after the detection of CPN; the negative QuantiFERON test turned positive during abatacept treatment in 1 patient (case 4) and biopsy of the nodule was necrotizing granuloma for the other one although tuberculosis bacilli were not detected (case 8). After antituberculosis treatment, there was no regression at the cavitary nodules.Respiratory symptoms were reported by 2 patients and constitutional symptoms by 2 patients while the others were asymptomatic during the diagnosis of CPN. All patients were seropositive, 2 patients had p ANCA (antinuclear cytoplasmic antibody)-positive, but the ELISA test for anti-MPO (myeloperoxidase) and PR3 (proteinase) were negative. Extensive examinations for microbial organisms (mycobacteria and opportunistic infections) were all negative .A total of 48 CTs were evaluated by two experienced pulmonary physicians. We are presenting CT findings showing cavitary and solid nodules of our patients in Fluorodeoxyglucose (FDG) PET/CT scan examination of nodules was performed to exclude malign conditions in 7 patients. We determined that both mediastinal lymphadenopathy (LAP) and cavitary-solitary nodules had increased uptake with a standardized uptake value (SUV) of 1.6\u20137.9 FDG. Salivary gland adenocarcinoma was detected in one of the patients with 12 FDG uptake value at the submandibular area, but biopsy from mediastinal lymph node (11 FDG) showed tuberculosis-negative necrotizing granuloma.We evaluated CTs of patients for the total (solid/cavitary) nodules at the end of 28 (3\u201365) months follow-up and 4 (36.3%) patients were diagnosed with regressed lesions while 7 (63.7%%) patients had progressive lesions compared to previous CTs and switch to biological DMARDs with different modes of action. In addition, improvement of the CPN lesions might be seen with non-TNF biologic treatment or targeted synthetic DMARDs ."} +{"text": "Scientific Reports 10.1038/s41598-021-03609-w, published online 10 January 2022Correction to: The Acknowledgements section in the original version of this Article was incomplete, where the grant number of one of the funding agencies was omitted.\u201cSP would like to acknowledge support of the National Science Centre of Poland within the OPUS programme.\u201dnow reads:\u201cSP would like to acknowledge support of the National Science Centre of Poland within the OPUS programme (2020/39/B/ST2/01524).\u201dThe original Article has been corrected."} +{"text": "In India, unsafe sex has been documented among truck drivers. This study explores the factors influencing their attitude of trucker towards condom use.A cross-sectional study design was adapted for this study in which 25 factors were chosen to assess attitude toward condom use on 7 point validated Likert scale UCLA Multidimensional Condom Attitude Scale on 5 subcomponents -Reliability, Pleasure, Stigma associated with condom use, embarrassment about negotiation and use of condom and about purchasing condom. Hundred truck drivers were recruited using convenient sampling and Mann-Whitney U and Kruskall Wallis Test were used to validate the subcomponents among those practicing unsafe sex.Positive attitudes regarding reliability and effectiveness of condom were significantly higher among adult entrants and those resting more than 10 hours during journey whereas positive attitude regarding pleasure associated with condoms and stigma towards it is significantly higher among truck drivers travelled long distances and resting more than 10 hours.Adolescent entrants, those who have not travelled long distances and not rested more than 10 hrs requires improvement in the attitude towards condom use. WHO reports globally 36.9 million people are living with HIV. 1In South-east Asia, 1.7 million people are living with HIV and number of people living with HIV in India is 2100000.2Sexual promiscuous lifestyle is common among truck drivers and therefore susceptible of acquiring HIV infection. 12There seems to be few studies highlighting the attitude toward condom use among truck drivers. This study was undertaken with an objective to assess the attitude towards condom use and its predictors among truck drivers at transhipment location in Meerut district, IndiaThis cross-sectional study was conducted at Trans-shipment area in Meerut district, India which is home to over two hundred transporters and over 500 trucks are available at any given point of time. Furthermore, a typical halt can range from thirty minutes to two days and work hours of most transporters are eleven hours.Hundred truck drivers were recruited who were having a valid driver's license from the trans-shipment area using convenient sampling procedure.A pre-tested validated questionnaire comprising closed ended questions was used to document socio-demographic-occupational profile and for assessment of attitude towards condom use University of California Los Angeles Multidimensional Condom Attitude Scale (UCLA MCAS) was used.13The truck drivers were briefed about the purpose of the study, importance of their participation, its consequential benefit to truck drivers and assurance of their confidentiality. After briefing them, the informed consent was taken from truck driver agreeing to participate and regardless of the participation, the truck drivers were given condoms and advices related to health issues. Truck drivers having wrong perception about condom were educated about the benefit of condom The pilot study, modification of questionnaire, recruitment of participants for main study and data analysis was done from a period of August 2014 to September 2015.Occupation profile: Type of truck drivers (based on distance traversed), average number of days away from home, average resting time during trip and type of entrant (adolescent or adult)Unsafe sex: Our criterion for unsafe sex was operationally defined as inconsistent use of condom with high risky sexual partners like CSW and MSM irrespective type of intercourse-vaginal, anal or oral (Fellatio) and practicing either Cunnilingus or Analingus or both.Attitude towards Condom Use: The 25 item UCLA MCAS 7-point Likert scale was used to assess the attitude towards condom use. The UCLA MCAS has 5 subscales (or domains) - Reliability and Effectiveness of Condoms, Pleasure associated with Condom, Stigma associated with condom use, Embarrassment about negotiation and use of condom and Embarrassment about purchasing condoms. 13Reliability and effectiveness subscale included 1) Condoms are an effective method of preventing the spread of Aids and other sexually transmitted diseases 2) Condoms are unreliable (reverse scored) 3) I think condoms are an excellent means of contraception 4) Condoms do not offer reliable protection (reversed score) 5) Condoms are an effective method of birth control. Pleasure associated with condoms included 1) Use of condom is an interruption of foreplay (reversed score) 2) Condoms ruin the sexual act (reversed the score) 3) Condoms are a lot of fun 4) The use of condom can make sex more stimulating 5) Condoms are uncomfortable for both parties (reversed score)Stigma associated with Condom use included 1)Women think men who use condoms are jerk (reversed score) 2)If a couple is about to have sex and the man suggests using a condom, it is less likely that they will have sex (reversed score) 3) People who suggest condom use are a little bit geeky (reversed score) 4) Men who suggest using a condom are really boring (reversed score) 5) A woman who suggests using a condom does not trust her partner (reversed score). Embarrassment about negotiation and use of condom include 1) It is really hard to bring up the issue of using condoms to my partners (reversed score) 2) When I suggest using a condom I am almost always embarrassed (reversed score) 3) It is easy to suggest my partner that we use a condom 4) I never know what to say when my partner and I need to talk about condoms or other protection (reversed score) 5) I am comfortable talking about condoms with my partner. Embarrassment about purchasing condoms include 1) I always feel really uncomfortable when I buy condoms (reversed score) 2) I don't think that buying condoms is awkward 3) It is very embarrassing to buy condoms (reversed score) 4) It would be embarrassing to be seen buying condoms in a store (reversed score) 5) It would be embarrassing to be seen buying condoms in a store (reversed score)The analysis was done in SPSS 21.The total score for each item = + + + + + + / Total Response (100)Mean score% for each subscale = (mean score \u2013 1)/Minimum value = 1 and maximum value = 7The mean score for individual participant in different subscales was computed and non-parametric test [Kruskall Wallis and Mann-Whitney U Test] were applied to find the predictors of attitude regarding condom use.The study was a component of a dissertation and Subharti Medical College Institutional Committee approved the dissertation (SMC/PG-13/2013).Of the 100 participants, most were married (72%), literate (90%), adult entrant (69%), travelled long distance (77%) average time away from home less than 10 days (71%) and resting during journey less than 10 hours (65%).The attitude among truck driver regarding reliability and effectiveness of condom is 88.3% , pleasure associated with condom is 70.3% , stigma associated with condom is 73.7% , embarrassment about negotiation and condom use is 76% and purchasing condoms is 75.8%.The mean score for attitude regarding reliability and effectiveness of condoms is significantly higher among adult entrants than adolescent entrants and those resting more than 10 hours during journey whereas mean score for regarding pleasure associated with condoms is significantly higher among truck drivers travelled long distances and resting more than 10 hours. Furthermore, the mean score for attitude regarding stigma associated with condom use is significantly higher among truck drivers travelled long distance and attitude regarding embarrassment about negotiation and use of condom was significantly higher among truck drivers resting more than 10 hours. However, mean score for attitude regarding embarrassment about purchasing condom use was significantly higher among adult entrants and those who have travelled long distance. This seems to be the first study for elaborative assessment of attitude toward condom use among truck driver population in India using UCLA Multidimensional Condom Attitude Scale. The findings of the study indicate in almost all domains the attitude of truck driver was far from satisfactory.This scale was used among 20 recruited community members assessing difference in attitude towards condom use between those consuming alcohol and does not consuming it.18The study is subjected to limitation because of small sample size recruited using convenience sample and social desirability bias may have influence on the response of the participants. Hence it is recommended the study be conducted on a large sample size using probability sampling.The age of the entrant, travelling long distances and resting time more than 10 hours were predictors significantly affecting attitude of truck drivers regarding condom use."} +{"text": "C) to the neurotoxic pathogenic form (PrPTSE) via a yet undefined but profoundly complex mechanism. Despite several decades of research on PrD, the basic understanding of where and how PrPC is transformed to the misfolded, aggregation-prone and pathogenic PrPTSE remains elusive. The primary clinical hallmarks of PrD include vacuolation-associated spongiform changes and PrPTSE accumulation in neural tissue together with astrogliosis. The difficulty in unravelling the disease mechanisms has been related to the rare occurrence and long incubation period (over decades) followed by a very short clinical phase (few months). Additional challenge in unravelling the disease is implicated to the unique nature of the agent, its complexity and strain diversity, resulting in the heterogeneity of the clinical manifestations and potentially diverse disease mechanisms. Recent advances in tissue isolation and processing techniques have identified novel means of intercellular communication through extracellular vesicles (EVs) that contribute to PrPTSE transmission in PrD. This review will comprehensively discuss PrPTSE transmission and neurotoxicity, focusing on the role of EVs in disease progression, biomarker discovery and potential therapeutic agents for the treatment of PrD.Prion diseases (PrD) or transmissible spongiform encephalopathies (TSE) are invariably fatal and pathogenic neurodegenerative disorders caused by the self-propagated misfolding of cellular prion protein (PrP TSE) of normal cellular prion protein (PrPC) (Prusiner Prion diseases (PrD) or transmissible spongiform encephalopathies (TSE) are progressively rapid and fatal neurodegenerative diseases (NDs) with a defining hallmark of vacuolation in the brain tissue , Gerstmann\u2013St\u00e4ussler\u2013Scheinker (GSS) and fatal familial insomnia (FFI) while sporadic CJD (sCJD) presents with disease aetiology from unknown origins. PrD with acquired aetiologies from exposure to pathogenic prions includes iatrogenic CJD (iCJD), vCJD, and kuru. To date, various human-to-human iCJD transmissions occurred due to incomplete decontamination of surgical equipment, corneal grafting, dura mater grafting, cadaveric pituitary-derived growth hormone or gonadotrophin, and blood transfusions denaturation, proteinase K (PK) treatment and high-performance liquid chromatography (HPLC) purification yielded the significant component of a single protein ranging 27\u201330\u00a0kDa in size (PrP 27\u201330) TSE isofoC has high endogenous expression in neurons and is encoded by only one exon out of three exons in the PrPC gene at chromosome 20 anchor at the C terminus (residue 230) and two N-linked glycans at residues 181 and 197. Nuclear magnetic resonance (NMR) examination of PrPC structure revealed an intrinsically disordered N-terminal tail (residues 23\u2013128), three \u03b1-helical regions (two of them linked by a disulphide bridge) and a short anti-parallel \u03b2-sheet , where it is packaged in extracellular vesicles and released into the extracellular environment was developed model \u2013based structure isolation of infectious prions from different prions strains for dynamic and multi-angle light scattering (DLS/MALS) analysis showed quaternary structure difference resulting in PrPTSE strain heterogeneity polymorphism fragment on SDS-PAGE gels, three different PrPres subtypes have been identified, which include type 1 (21\u00a0kDa), type 2 (19\u00a0kDa) and type intermediate is a technique that converts normal brain homogenate PrPTSE deposition are the characteristic features of prion-infected brains, the mechanism of neurotoxicity has remained elusive. However, several studies have investigated the synergistic effect generated by the interaction of PrPC and PrPTSE, providing some explanation on the neurotoxic effects of PrPTSE. Grafting neural tissue overexpressing PrPC into PrPC null mice brains and intracerebrally injecting scrapie prions produced severe histopathological changes exclusively in the grafted tissue starvation followed by ATP depletion and exosomes classified based on biogenetic pathway and size. Apoptotic bodies (500\u20135000\u00a0nm) arise from the cell fragmentation during apoptosis, microvesicles (200\u20131000\u00a0nm) from outward budding and shedding from the plasma membrane, and exosomes 40\u2013200\u00a0nm) which are released intercellularly following production via the endosomal pathway and fusion of the MVB to the plasma membrane , and many have predicted targets in crucial neuronal signalling pathways. This suggests that EVs could carry brain-associated miRNAs and into the blood play key roles in gene regulation either by inducing mRNA degradation or repression of mRNA translation. A plethora of miRNAs are present in the brain, indicating that complex physiological and neuronal development functions of miRNAs are more enriched in the brain regions, which shows the complex physiological functions of the brain , a regulator of ceramide biosynthesis, reduced exosomes as well as miRNA secretion, an effect that was reversed following overexpression \u2013infected N2a cells overexpressing murine prion protein demonstrated upregulation in the redox chaperone, protein disulphide isomerase (PDI) and ATPase (complex V). A more recent study validated mitochondrial respiratory chain deficiency in human sCJD brain temporal cortex with immunohistochemistry, demonstrating a loss of all mitochondrial complexes (I\u2013V) and Alzheimer\u2019s disease (AD). An early study of scrapie-infected hamster brain cerebral cortex transmission electron microscopy images depicted alterations in mitochondrial morphology and depletion of mitochondrial matrix and cristae \u2013derived EVs from human placenta intravenously delivered to multiple sclerosis mice demonstrated increased motor abilities, reduced DNA damage and increased myelination \u2013derived EVs injected into the bloodstream ameliorated neuroinflammation and increased cognitive function in immunocompetent mice (Leavitt et al. EV research is a burgeoning field elucidating the dynamic nature of intercellular communication in the local and distal areas of the body, and has opened a new horizon to decipher the fundamental biological processes in health and disease. Studies exploiting EVs as the biomarker source and their subsequent role in pathogenic and neurotoxic processes aid a better understanding of the complexity of PrD. The gaps in the study of proteomics and lipidomic cargo from the infectious EVs of several prion strains would help to reveal common neurotoxicity-related pathways. Moreover, the functional study of infectious prion EVs in communication with the glial cells can reveal these EVs\u2019 immunomodulatory and inflammatory effects. While secondary lymphoid organs, including the spleen, are indicated as an early accumulation site for prion replication following peripheral prion infection, isolating EVs from these organs for infectivity and cargo assessment would result in better understanding of EVs\u2019 associated roles. Future studies utilising emerging technologies to examine the nanoscale world of EVs will shed more light on this growing field, promoting strain-specific biomarker discovery for disease diagnosis and enabling the engineering of EVs for disease treatment."} +{"text": "This study aimed to use data analytics to retrospectively identify the prevalence of inpatients across a system of hospitals with a BAAL who received and tolerated the culprit or related beta-lactam (BL) without proper documentation in the allergy profile of the electronic medical record (EMR).

Inactivated and viral vector were the most common vaccine types received by the PLHIV as the first and second doses , while mRNA vaccine was the most commonly used as a booster dose (57%). For the first and second vaccine doses, the most common AEs were fever (15% and 11%) and injection site pain (11% and 11%). The mRNA vaccine significantly caused more overall AEs, injection pain, fatigue, and rashes than the other two types, while the mRNA and viral vector vaccines significantly caused more fever than the inactivated vaccine. For a booster dose, viral vector vaccine significantly caused more injection site pain and headache than the other two types. Most of the PLHIV reported that the AE intensity was similar between the first and second doses (49%) and was more for a booster dose compared to the first dose (50%). The majority of all AEs of the first, second and booster doses spontaneously recovered without treatment or required symptomatic treatment without hospitalization . By multivariable analysis, receipt of viral vector or mRNA vaccine and age less than 40 years were independently associated with any AEs of the primary series vaccines, while having AEs from the previous dose and female sex were factors associated with any AEs of a booster vaccine.The three types of COVID-19 vaccines were generally safe among PLHIV. Most of the AEs were non-severe and did not require hospitalization.

Moench] utilizes the cytoplasmic-nuclear male sterility (CMS) system for seed production and subsequently harnesses heterosis. Since the cost of developing and evaluating inbred and hybrid lines in the CMS system is costly and time-consuming, genomic prediction of parental lines and hybrids is based on genetic data genotype. We generated 602 hybrids by crossing two female (A) lines with 301 diverse and elite male (R) lines from the sorghum association panel and collected phenotypic data for agronomic traits over two years. We genotyped the inbred parents using whole genome resequencing and used 2,687,342 high quality single nucleotide polymorphisms for genomic prediction. For grain yield, the experimental hybrids exhibited an average mid-parent heterosis of 40%. Genomic best linear unbiased prediction (GBLUP) for hybrid performance yielded an average prediction accuracy of 0.76\u20130.93 under the prediction scenario where both parental lines in validation sets were included in the training sets (T2). However, when only female tester was shared between training and validation sets (T1F), prediction accuracies declined by 12\u201390%, with plant height showing the greatest decline. Mean accuracies for predicting the general combining ability of male parents ranged from 0.33 to 0.62 for all traits.

The modification was done by blocking each complete replication into smaller blocks based on previously observed maturity and height phenotypes for the male parent of the hybrids to avoid shading effect of taller lines on neighboring plants. There were a total of 40 blocks per replication and each block consisted of 30 individual plots. Each plot had two rows with a row length of 6.096 m and a row spacing of 0.762 m. The experimental hybrids, their parental lines and check hybrid variety (83P17) were randomized completely for each small block nested within each replication. Preplant fertilizer was blended based on soil sample results and per field recommendations for cereal grain production. In 2019, the fertilizer blend consisted of granular muriate of potash at 300 kg haPhenotypic data were collected for days to anthesis (DTA) when about 50% of the primary panicles in the plot were at mid-anthesis. Plant height (PH) was measured from the base of the plant to the top of the representative panicle within the plot after physiological maturity. Plants were harvested when the majority of the plants in the plot reached post-physiological maturity (grain moisture below 18%) using a Wintersteiger Delta two row combine plot harvester.

The comSince the possible hybrid combinations even in a medium sized breeding program far exceeds the capacity to test them in actual hybrid crosses, one of the main motivation for the use of GP in hybrid breeding is to be able to estimate hybrid genetic value of those untested hybrid crosses or only female parent (T1F) were shared between training and validation sets to understand the effect of parent testing on the accuracy of single cross predictions. While single-cross performance was predicted with high accuracy in T2 scenario, a strong decline (12\u201390%) in prediction accuracy was observed in T1F compared to T2. This is expected because the predictions from the model in T2 rely not only on kinship between male parents , as in the case of T1F, but also on information from other crosses in the training set that involves the male parent of predicted hybrid with the other female tester. Plant height showed the greatest decline in prediction accuracy in T1F, which could be due to very limited phenotypic variability among female lines for PH, and as a result, accuracy for PH could have been driven primarily by male parent. GP of sorghum hybrids using GBLUP model and cross-validation involving leave one parent out strategy (similar to our T1F) showed mean prediction accuracies (0.31\u20130.54) for grain yield that was similar to accuracy from our T1F prediction scenario (Prediction of testcross performance of inbred lines in hybrid combinations has been studied across multiple crop species ( studied .

No prior studies have specifically explored protective factors against suicide and interpersonal violence in Azerbaijan.This study aims to address this gap and to identify culturally relevant protective factors against suicide and violence against women in Azerbaijan.A total of 51 women with lived experience and mental health providers participated in either in-depth qualitative interviews or focus groups. The interview guide for the focus groups and one-on-one interviews were developed by the study PI. A list of questions served as the basis for the discussions and was revised and expanded as the groups progressed. For the qualitative analyses, conventional content analysis following a systematic process of coding and classification was utilized.Three main protective factors against suicide were identified: 1) psychological support (33%); 2) psychoeducation to raise awareness of suicide and reduce stigma (28%); and 3) providing financial opportunities/supports (10%) and for violence against women 1) advocacy (28%); 2) psychological support (28%); and 3) changing cultural values (17%).This study fills a much-needed gap in our understanding of suicide and violence against women in Muslim populations.

To address this gap, our study evaluates the effect of universal gloving (UG) for all patient contact to prevent transmission from these patients. However, the gloving intervention involves complex behavioral practices with wide variations in compliance; thus, data on intervention implementation provides critical context.

We evaluated some of the potential risks and proposed redesign of infection prevention and control measures in April 2021 to improve the overall clean care at the orthopedic outpatient clinic. Methods: We conducted an operational study to redesign various components of clean care using a before-and-after evaluation of infection risk. The study was led by an IPC nurse and was supported by all levels of stakeholders at Sardjito Hospital, a referral and academic hospital in Yogyakarta, Indonesia, during May\u2013September 2021. Results: The redesigned components covered continuing professional development (CPD) through a workshop on clean care and wound care for doctors and nurses. The workshop also encouraged high-level management to make several important changes: (1) to redistribute medical staff schedules, (2) to start online patient registration to better distribute and decrease patient loads, (3) to set up the waiting room as well as the dressing room with strictly separate between dirty and clean areas, (4) to schedule daily general disinfection at noon during service hours, and (5) to perform routine air disinfection after daily clinic services as well as placing an additional portable HEPA filter for continuous air disinfection. After the these changes, during 2021, 7 SSIs occurred among postoperative orthopedic implant patients, a decrease of 85%. We observed more clean and neat rooms without patient overcrowding as well as easy and comfortable flow of patients and staff. Environmental pathogen germ counts decreased significantly.

The high incidence in women living with HIV and late presentation often at advanced stages of ICC with limited treatment facilities often result in early mortality. We sought to compare the epidemiologic characteristics and survival differences in HIV status of ICC patients in Nigeria.We conducted a cohort study at two federal academic hospital-based research sites in Jos University Teaching Hospital, and Lagos University Teaching Hospital Nigeria, between March 2018 and September 2022. We enrolled women with histologically confirmed ICC with known HIV status, and FIGO staging as part of the United States of America\u2019s National Institutes of Health/National Cancer Institute funded project titled \u2018Epigenomic Biomarkers of HIV-Associated Cancers in Nigeria\u2019. The primary outcome was all-cause mortality with assessment of overall survival (OS) and time to death after ICC diagnosis. OS distribution was estimated using the method of Kaplan-Meier and compared between groups using the log-rank test.A total of 239 women with confirmed ICC were enrolled and included in this analysis, of whom 192 (80.3%) were HIV-negative (HIV-/ICC+), and 47 (19.7%) were HIV-positive (HIV+/ICC+). The HIV+/ICC) patients were younger with median age 46 (IQR: 40\u201351) years compared to 57 (IQR: 45\u201366) among HIV-/ICC+) , with 12-month OS 84.1% (95%CI: 75% - 90%) and 67.6% (95%CI: 42%\u221284%) respectively.ICC is diagnosed at a relatively young age in women living with HIV, with a significantly lower overall survival probability compared to women without HIV. The trend of presentation and diagnosis at advanced stages in women living with HIV could partly explain the differences in overall survival. The World Health Organization (WHO) global estimates showed that 604,127 new cases of invasive cervical cancer (ICC) and 341,831 deaths occurred in 2020.Late presentation and diagnosis, lack of access to care, low resources, and ineffective treatment of ICC have contributed to the high mortality and poor survival for cases of ICC in Nigeria and most low- and middle-income countries (LMICs). \u20138 The dePrevious epidemiologic studies have focused on the survival outcomes of patients with cervical cancer based on stage at diagnosis, access to treatment by surgery or chemoradiation, but few have compared survival outcomes by HIV status., 11, 12 We conducted a cohort study at two academic hospital-based research sites in Jos and Lagos , Nigeria.

For categorical variables, frequencies and percentages were reported, and proportions were compared using Fisher\u2019s exact test. Frequencies of missing observations were tabulated, and missing observations were not included in these descriptive analyses.Primary objective was to determine the association between HIV status and overall survival (OS) among ICC+ patients. OS distribution was estimated using the method of Kaplan-Meier, and survival estimates are reported with the corresponding 95% confidence bands, 25th, median, and 75th percentiles survival times are presented. Overall survival was compared between groups using the log-rank test. Overall survival was estimated for HIV+ and HIV- groups, and by study site.Statistical analyses were performed using R v. 4.2.2 statistical software, and usiBetween March 18th, 2018, and September 30th, 2022, a total of 239 women with confirmed invasive cervical cancer were enrolled and are included in this analysis, of whom 192 (80.3%) were HIV-negative (HIV-/ICC+), and 47 (19.7%) were HIV-positive (HIV+/ICC+).The median age at study enrollment was 53 years (IQR: 44\u201365) among the ICC+ participants overall. HIV-positive patients were younger with median age 46 (IQR: 40\u201351) years compared to 57 (IQR: 45\u201366) among HIV-negative ; had a higher level of education with only 10.6% having no formal education as compared to 32.6% in the HIV- groups (p<.001); and a higher number of lifetime sexual partners with median of 3 (IQR: 1\u20134) partners among HIV+ patients vs. 1 (IQR: 1\u20132) in the HIV- group (p<0.001). Women without HIV had a higher number of childbirths but comparable age at first childbirth (median 20 years old in both groups) and BMI (median 25 in both groups) to women with HIV. The most common histopathologic variant of ICC was squamous cell carcinoma in 80.4% of all cases and was similar among HIV+ and HIV- women . The majority of patients (68.1%) had moderately differentiated tumor grade , and the histopathologic variants and tumor grading were comparable in both groups. HIV+ women tended to be diagnosed with advanced stage more frequently (64.9%) than HIV- women (47.9%) although the difference was not statistically significant (p=0.10). Other descriptive statistics of the participants with ICC by HIV status have been summarized in Following diagnosis and enrollment of participants with ICC, types of treatments received were not significantly different for women with HIV and without HIV as shown in We also compared the survival outcomes by HIV status and founThis manuscript discusses the descriptive epidemiologic characteristics and survival outcomes of women with and without HIV diagnosed with invasive cervical cancer enrolled in two large tertiary academic medical centers in Nigeria. We found that women with HIV were 11 years younger at diagnosis of ICC compared to women without HIV. Although there were no significant differences in baseline BMI, FIGO staging at diagnosis, histopathologic variants, tumor grading and types of treatment received, we found that overall survival was significantly better in ICC participants without HIV compared to those living with HIV. Our findings were similar with a larger Zambian cohort of ICC patients that showed women with HIV were 10 years younger at diagnosis with a poorer prognosis compared to those without HIV.The relatively low survival rates in our primary analyses likely reflect the fact that treatment options for cervical cancer are greatly limited in most LMIC settings including Nigeria, with a paucity of trained gynecologic oncology specialists and limited cancer centers with chemoradiation facilities. A recent review has corroborated the poor treatment facilities, particularly the lack of radiotherapy centers to compensate the poor surgical services for gynecological cancers in sub-Saharan African settings.These chaThe paucity of trained gynecologic oncologists and limited compliance to treatment guidelines is widespread in LMICs. This has been reported in a related study in Botswana in southern Africa that showed comparable findings of women with HIV being diagnosed with ICC at a much younger age compared to women without HIV, and the hazards of early mortality were significantly higher in women with HIV. The effeThe above findings have implications given the evidence of high incidence of cervical cancer in women living with HIV. It is imOur data showed comparable histologic types of ICC and tumor grading irrespective of HIV status. As in most literature, the most common histologic variant found in both HIV positive, and HIV negative cervical cancer tumors is squamous cell carcinoma variants. A previous study report of a retrospective cervical cancer cohort found that women living with HIV were significantly more likely to be diagnosed at advanced stages of cancer compared to HIV negative women. Our dataA previous histopathologic study of ICC showed that the commonest variant in both HIV positive and negative patients is the squamous cell type, and as in our study cohort is diagnosed at younger age in HIV-infected patients compared to HIV-negative patients. The studOur study findings are unique and are based on the strength of the enrollment protocol jointly developed by investigators from both participating sites in two distinct geographic zones in Nigeria in collaboration with Northwestern University. The histologic diagnoses and tumor grading were further subjected to peer review and quality improvement through a telepathology scanning and video conferencing platform involving the two participating sites and Northwestern pathology core. To the bCervical cancer remains a significant public health concern, diagnosed at a relatively young age in women living with HIV, with a significantly lower overall survival probability compared to women without HIV. The trend of presentation and diagnosis of this cancer at advanced stages in women living with HIV could partly explain the differences in overall survival. Strategies that strengthen access to primary prevention, early detection through screening, and early provision of effective treatment should be prioritized for all women- particularly those infected with HIV.Supplement 1"} +{"text": "Frontotemporal dementia (FTD) encompasses a group of clinically, genetically and pathologically heterogeneous neurodegenerative disorders that mainly affect people under the age of 64 years.

Using delayed fluorescence imaging of indocyanine green (ICG), a method called second window ICG (SWIG), we have shown that high dose ICG persists in burn wounds in both animals and patients 24 hours after infusion. The necrotic avidity of ICG is proposed as the underlying mechanism, although inflammation also likely has a role. The objective of this study is to examine the hypothesis at both the tissue and cellular levels.To examine the localization of ICG in burn tissue, 4-mm biopsies taken from burn patients who underwent SWIG were embedded and sequentially sectioned for H&E (tissue architecture) and LDH (tissue viability) and ICG fluorescence imaging. To examine whether ICG preferentially binds to necrotic cells, primary skin cells (fibroblasts or keratinocytes) were subjected to thermal injury at 65\u00baC for 0 (untreated), 2.5 or 5 minutes. The cells were subsequently incubated with ICG at concentrations ranging from 0.5 to 5 \u03bcg/mL at 37\u00baC for 30 minutes. A necrosis and apoptosis detection kit with Yo-Pro\u2122-1 and propidium iodide (PI) was used to differentiate live, apoptotic and necrotic cell populations in flow cytometry. The ICG florescence intensity of each cell population was measured with flow cytometry.The fluorescence microscopic imaging revealed that ICG intensity was most intense in the superficial severely thermally-injured tissue and gradually decreased with depth. This zone of high ICG intensity was co-localized with high cellularity (shown in H&E) consisting of a mixture of nonviable skin cells (shown in LDH) and inflammatory infiltrates. Using flow cytometry, the optimal concentration of ICG with the highest ICG florescence median intensity (FMI) and the best separation of live, apoptotic and necrotic cell populations was 2.5 \u03bcg/mL, which was used for subsequent flow cytometry experiments. For both fibroblasts and keratinocytes, the ICG FMI was significantly higher in the necrotic cell population than that of either the live or apoptotic cell population, suggesting higher affinity of ICG to necrotic cells. The ICG FMI of necrotic cells with longer heat exposure (5 minutes) was significantly higher than that of necrotic cells with shorter heat exposure (2.5 minutes), suggesting that the binding sites for ICG increase with the degree of thermal injury.This study demonstrates the necrotic avidity of ICG in burned skin tissue and two primary skin cell types. Further studies are needed to study the ICG binding characteristics with inflammatory cell populations and single cell suspensions dissociated from human burn tissue.This, along with our pilot study of SWIG in patients, supports the feasibility of SWIG in guiding surgical decision-making in burn excision by defining thresholds of fluorescence intensity values."} +{"text": "PLOS Biology demonstrates that combined therapy targeting enhancer of zeste homolog 2 (EZH2) and histone deacetylases (HDACs) may sensitize CRPC to both epigenetic and standard therapies.Development of resistance in castration-resistant prostate cancer (CRPC) involves epigenetic pathways. A new study in Development of resistance in castration-resistant prostate cancer (CRPC) involves epigenetic pathways involving EZH2 and HDACs. This Primer explores a PLOS Biology study showing that combined epigenetic therapy targeting these enzymes can activate cellular stress pathways, which may sensitize CRPC to both epigenetic and standard therapies. Despite advances in diagnosis and treatment, prostate cancer remains the second-leading cause of cancer-related death in men and a significant health concern. This is attributable to its high incidence (an estimated 1 in 8 men are diagnosed with prostate cancer), late stage of diagnosis and development of treatment resistance. Prostate cancer develops in the prostate gland mainly due to dysregulated androgen signaling through the androgen receptor. Androgen receptor has a critical role in regulating the growth and differentiation of prostate cells and is frequently overexpressed or mutated in prostate cancer cells. Suppression of androgen receptor signaling by androgen deprivation therapy (ADT), which involves blocking the production or activity of androgens, has been a major treatment approach for prostate cancer. However, the effectiveness of ADT is limited, and prostate cancer cells can eventually develop resistance to this therapy by finding alternative ways to activate the androgen receptor signaling pathway, leading to development of castration-resistant prostate cancer (CRPC). CRPC consequently is an advanced stage of prostate cancer with limited treatment options. Understanding the biological mechanisms involved in maintenance of CRPC and ways to directly target the resistance mechanisms are therefore critical.Development of the CRPC state involves epigenetic reprogramming in response to persistent androgen receptor targeting, wherein the epigenetic enzyme enhancer of zeste homolog 2 (EZH2) has a critical role. EZH2 is a histone methyltransferase that complexes with polycomb repressive complex 2 (PRC2) components to catalyze the trimethylation of histone H3 lysine 27 (H3K27me3), which is associated with gene repression . EZH2 ovIn addition to EZH2, another key epigenetic enzyme important in CRPC is the class of histone deacetylases (HDACs). HDACs are enzymes that remove acetyl groups from histone proteins in chromatin, which can lead to a tighter packing of DNA and a reduction in gene expression . HDACs aPLOS Biology, Schade and colleagues found that targeting the epigenetic functions of both EZH2 and HDACs together had a synergistic effect in killing CRPC cells, independent of androgen receptor activity [ATF3, which resulted in an acute cytotoxic effect both in vivo and in in vitro models of aggressive CRPCs. Schade and colleagues hypothesized that genes suppressed by EZH2 are incompletely derepressed upon inhibiting EZH2 alone because of sustained presence of deacetylated histones at the target gene regulatory elements by performing expression analysis to identify up-regulated genes and pathways, ChIP-seq, and siRNA knock-down screens. reatment .

WGS found the 3 patient isolates were identical (0 single nucleotide polymorphism (SNP) difference). The same healthcare personnel (HCP) team had performed the procedures for all 3 infected patients. A site visit identified gaps in IC and injection safety practices. One HCP who provided care to all 3 patients had visible skin lesions on their hands, wore bracelets, and was unaware of a facility policy to report if they were unable to perform adequate hand hygiene. MSSA screening cultures were collected from 3 involved HCP and were positive in only the HCP with skin lesions. WGS showed that the HCP MSSA isolates were highly related to the patient isolates (0-2 SNP difference). We advised the facility to develop an IC program tailored to the procedures performed, including adverse event surveillance, adherence monitoring of hand hygiene and environmental services practices, and attention to injection safety. The MSSA colonized HCP was referred for treatment of their skin condition and decolonization and was restricted from patient care until their skin condition improved.Phylogenetic tree for MSSAA combination of injection safety and hand hygiene lapses led to MSSA transmission from an HCP to 3 patients.

Unlike cell membrane G-protein-coupled receptors that elicit biological responses through second messenger signaling, nuclear receptors are a large family of transcription factors that primarily bind to genomic DNA and regulate the expression of target genes, although non-genomic actions of nuclear receptors have also been identified . These studies demonstrate that 2ME2 downregulates AT1 receptor expression in the kidney cortex and liver without impacting angiotensin II binding affinity . The blood pressure-lowering effect of 2ME2 is independent of sex in Wistar rats infused with angiotensin II. In addition, prolonged 2ME2 treatment decreases heart rate and body weight in male SHRs. Collectively, this study demonstrated that 2ME2 plays a critical role in regulating the renin\u2013angiotensin system and resting heart rate through the downregulation of angiotensinogen and AT1 receptor . Sundin et al. determined that turbulent kinetic energy of blood flow in the healthy human thoracic aorta increases with dobutamine stress and is strongly related to cardiac output. Quantification by magnetic resonance imaging (MRI) was performed to determine 4D flow-based hemodynamic parameters and turbulent kinetic energy and evaluate dobutamine stress on thoracic aortas. Findings of this study demonstrate that turbulent kinetic energy with cardiac stress could serve as a risk assessment for aortic disease development . Future studies that focus on the therapeutic potential of 2ME2 to treat hypertension and MRI-based 4D turbulent kinetic measurement to assess cardiovascular disease progression are required.Two original research articles provide novel findings on the regulation of angiotensin type 1 (AT1) receptors by the estrogen metabolite, 2-methoxyestradiol (2ME2), and quantification of turbulent flow and aortic disease development.

A typical presentation includes dyspnea, tachycardia, and chest pain. Importantly, serial cardiac exams in such high-risk patients can detect other concurrent pathologies. We present an unusual case of a patient who initially presented with an acute circumferential pericardial effusion and upon serial POCUS exams developed an unexpected Takotsubo cardiomyopathy in the setting of cardiac tamponade. A 63-year-old woman with a past medical history of Human Immunodeficiency Virus, asthma, and previously treated Hodgkin\u2019s lymphoma presented to the emergency department with 3 weeks of worsening shortness of breath. On initial assessment in the emergency department, the patient was hemodynamically unstable with a heart rate of 140 beats per minute (bpm) and a blood pressure of 88/68 mm Hg. Bedside point of care ultrasound (POCUS) was performed and demonstrated a moderate circumferential pericardial effusion with normal left ventricular function and a collapsible inferior vena-cava (IVC). Intravenous fluids were initiated with resolution of the patient\u2019s hemodynamic instability (Video S1). A computer tomography (CT) of the chest was also obtained in the emergency department which showed extensive mediastinal lymphadenopathy with right middle lobe consolidation. The patient was admitted for evaluation of the pericardial effusion and CT findings. Forty-eight hours after admission, the patient reported persistent midsternal chest pain and shortness of breath with a blood pressure of 110/60 mm Hg, heart rate of 127 bpm, and an oxygen saturation of 100% on 2-liters nasal cannula. Repeat troponin I was elevated at 1.02ng/ml (ref - <0.03 ng/ml). POCUS was performed which revealed mid-to apical left ventricular (LV) akinesis and an interval reduction of LV function along with right atrial systolic collapse, right ventricular diastolic collapse and a plethoric IVC (Video S2). Limited transthoracic echocardiogram done by the echocardiography lab shortly after confirmed the findings. These findings were concerning for Takotsubo/stress induced cardiomyopathy in the setting of tamponade physiology. The patient underwent a pericardiocentesis with removal of 240 mL of fluid with improvement of tachycardia and dyspnea. Formal echocardiography 48 hours after the procedure showed minimal residual effusion with improvement of LV function, which returned to normal within a week (Video S3). Cytology of the pericardial fluid showed inflammatory and mesothelial cells with no evidence of malignant cells. However, subsequent lymph node biopsy revealed recurrence of Hodgkin lymphoma to which her pericardial effusion was attributed. Cardiac tamponade is a pericardial syndrome characterized by impairment of diastolic filling of the ventricles causing reduction of cardiac output. The classically advanced signs of tamponade described as hypotension, distension of jugular veins, and diminished heart sounds (Becks Triad) are present in a minority of patients. The most common initial presenting symptoms are dyspnea and tachycardia, which may be present in the absence of hypotension Echocardiographic evaluation of tamponade includes: i) Quantity and quality of pericardial fluid ii) Systolic right atrial collapse iii) Diastolic right ventricular size and variability with the respiratory cycle iv) Interventricular septal shift of the left ventricle during inspiration v) Collapsibility of IVC Diastolic right ventricular collapse is specific for tamponade while IVC plethora is highly sensitive. Systolic right atrial collapse is often the earliest sign of tamponade. Comprehensive or advanced critical care echocardiography can be used to detect exaggerated respiratory cycle changes in mitral and tricuspid valve in-flow velocities as a surrogate for pulsus paradoxus In this patient the initial POCUS exam revealed a moderate sized pericardial effusion with a fully collapsible IVC making tamponade physiology less likely. When the patient developed new onset chest pain and shortness of breath this raised the concern for worsening tamponade. A repeat ultrasound revealed an unexpected finding of stress induced cardiomyopathy which can potentially be attributable to progressive tamponade development. Potentially the tamponade was further exacerbated by left ventricular dysfunction.In dog models right atrial and ventricular collapse occurred with significantly smaller volumes of pericardial fluid in the setting of induced left ventricular dysfunction Takotsubo-associated myocardial dysfunction is irrespective of vascular territories, and commonly presents as transient mid to apical akinesia, hypokinesia, or dyskinesia in the absence of obstructive coronary disease. Other findings include circumferential apical dilatation , basal hyperkinesia and a severely reduced left ventricular function This case highlights the importance of serial cardiac POCUS examinations in the evaluation of pericardial effusion. Additionally, it highlights the importance of recognizing an acute concurrent cardiac pathology that can quickly lead to a vicious cycle of cardiac dysfunction leading to decompensation.

Patterns of differences are now being recognized as patients\u2019 age and these patterns bring about new opportunities for disease prevention and treatment. Low bone mineral density (BMD) has been reported in many studies of males and females with DS yet the specific effects of trisomy 21 on the skeleton remain poorly defined. Therefore we determined the bone phenotype and measured bone turnover markers in the murine DS model Ts65Dn. Male Ts65Dn DS mice are infertile and display a profound low bone mass phenotype that deteriorates with age. The low bone mass was correlated with significantly decreased osteoblast and osteoclast development, decreased bone biochemical markers, a diminished bone formation rate and reduced mechanical strength. The low bone mass observed in 3 month old Ts65Dn mice was significantly increased after 4 weeks of intermittent PTH treatment. These studies provide novel insight into the cause of the profound bone fragility in DS and identify PTH as a potential anabolic agent in the adult low bone mass DS population. Although Down syndrome (DS) was initially described in 1866 Several investigators, including ourselves have reported that adults (and children) with DS have lower bone mass, expressed as BMD, especially in the lumbar spine, compared with their peers without mental retardation or with mental retardation but without DS The Ts65Dn mouse is one of several mouse models of DS that has been developed to investigate the pathology of DS phenotypes 16)65Dn (Ts65Dn) mouse model of DS at both 3 and 24 months of age To investigate bone health in DS, we determined the skeletal phenotype of the Ts at both 3 months and 24 months of age .

Sub-region analysis of the mid-shaft of the femur revealed that trisomy significantly decreased cortical thickness in both 3-month old were used.Mice were treated with daily i.p. injections of 30 or 80 ug/kg PTH(1\u201334), or vehicle control, for 28 days. PTH increased whole-body BMD in both 3 month old WT and Ts65Dn mice as determined by DXA . In WT mIntermittent PTH treatment caused an approximately equivalent increase in BV/TV in both WT and Ts65Dn mice . PTH incThe observed increase in trabecular bone mass and volume was mediated by a PTH-stimulated increase in mineral apposition rate and bone formation . Osteoblex vivo bone marrow cultures, the differentiation capacity of osteoblasts and osteoclasts were impaired in Ts65Dn mice, demonstrating the cell intrinsic nature of the bone phenotype, and confirming both mesenchymal and hematopoetic lineages as targets of trisomy 21. Interestingly, and as reported by others The present study demonstrated that Ts65Dn DS mice have lower trabecular bone volume and trabecular number and higher trabecular separation in the proximal tibia and distal femur as well as decreased cortical thickness and strength compared with WT littermates. The low bone mass phenotype is consistent with the human DS population that also displays a low BMD due to decreased bone turnover Ts65Dn mice at 3-months and 24-months of age have significant decreases in trabecular and cortical bone. The BV/TV and trabecular number are significantly decreased at both ages. With the decreased number of trabeculae, there was a subsequent significant increase in trabecular spacing. Interestingly, trabecular thickness was not significantly affected, suggesting that the fundamental mechanism controlling the development of trabeculae is intact in trisomic Ts65Dn mice, but the rate at which they are generated is decreased. These results extend those of Blazek Other DS mouse models have been developed and their bone phenotype investigated The low bone mass phenotype of Ts65Dn male mice like people with DS is profound and is the result of decreased bone turnover. The decreased bone turnover is unexpected, given the hypogonadism and infertility associated with the disorder in humans ex vivo bone marrow cultures and in the histomorphometric analysis of tibias from 3-month old Ts65Dn mice. In ex vivo cultures, both osteoblast and osteoclast differentiation was significantly decreased in Ts65Dn compared with control. In vivo, osteoblast number per bone surface, osteoclast number per bone surface and bone formation rate were all significantly decreased. These observations suggest an intrinsic defect in both the mesenchymal and the hematopoetic cell lineages. While the defect in megakaryocyotopoiesis in DS has been well studied in humans and is recapitulated in the Ts65Dn mouse The defect in both osteoblast and osteoclast differentiation in Ts65Dn mice was observed in both th decade of life and are presenting in increasing numbers with low bone mass and fracture Histological evaluation of the bone marrow confirmed the megakaryocyte hyperplasia as has been reported in Ts65Dn mice and in DS patients Collectively, these observations provide evidence that the low bone mass observed in humans with DS and Ts65Dn mice is due to a cellular defect in both the hematopoietic and mesenchymal lineages, such that aneuploidy\u2019s effects on the available pool of precursor cells decreases their capacity for normal differentiation and function. Thus, fewer cells differentiating into functional osteoblasts and osteoclasts results in the accrual of lower bone mass, which is a mechanism fundamentally distinct from the high bone turnover observed in hypogonadal women and men, where increased numbers and activity of cells leads to low bone mass.In support of this idea, the Ts65Dn mice demonstrate a lifelong deficit in bone turnover, such that normal peak adult bone mass is never achieved. It is important to note that the serum bone turnover markers of control animals revealed the expected age-dependent increases in both formation and resorption markers, whereas markers in Ts65Dn mice do not increase with age and are consistently lower compared with control throughout the life of the mice. If this temporal difference in bone turnover is recapitulated in humans with DS, it would indicate that low bone turnover is sustained in DS resulting in lower bone accrual and is an area that we are actively investigating. Perhaps most importantly, our studies provide the first data to demonstrate the efficacy of a bone anabolic agent in the treatment of low bone mass in DS and call into question the routine use of bisphosphonates (which decrease bone turnover) in this patient population.Intermittent PTH therapy increases bone formation by stimulating osteoblast numbers at sites of bone remodeling, where old bone is replaced with new by the concerted efforts of both osteoclasts and osteoblasts Thus, these data provide a clearer understanding of the cellular mechanisms leading to the low bone mass in DS, suggest a new direction for treatment and provide a relevant animal model for continued studies of the skeleton in DS. Given the elevated fracture risk and rate in DS patients our data provide the rationale to consider bone anabolic therapies in DS patients with low bone mass.ad libitum and a 12-hr light:dark cycle. Only male mice were evaluated due to the decreased fertility of Ts65Dn male mice and the necessity of Ts65Dn female mice for colony maintenance. Animals were purchased at 6 weeks and aged as required. Some mice were aged and maintained at UAMS for up to 24 months.All animal handling and experimentation was performed in accordance with approved University of Arkansas for Medical Sciences (UAMS) institutional guidelines and protocols and approved by the UAMS Institutional Animal Care and Use Committee (IACUC).

Upon arrival they were housed individually with food and water available For bone phenotyping, animals were sacrificed at 3 months and 24 months and long bones and spines harvested. Some three month old animals were injected with calcein (administered 8 days prior to sacrifice) and alizarin red S (Sigma) or alizarin red complexone (Sigma) (administered 2 days prior to sacrifice), for subsequent determination of dynamic parameters of bone histomorphometry with an inter-label distance of 6 days as described In Ts65Dn and WT mice, serum was extracted from blood drawn at sacrifice and serum procollagen-1 N-terminal peptide (P1NP) and tartrate resistant acid phosphatase (TRAP) measured.

Femoral cortical geometry was assessed in a 1-mm-long region centered at the femoral midshaft. The outer contour of the bone was found automatically using the built-in manufacturer\u2019s contouring tool.

Its endogenous ligand, tuberoinfundibular peptide of 39 residues (TIP39), is synthesized in only two brain regions, within the posterior thalamus and the lateral pons. TIP39-expressing neurons have a widespread projection pattern, which matches the PTH2R distribution in the brain. Neuroendocrine centers including the preoptic area, the periventricular, paraventricular, and arcuate nuclei contain the highest density of PTH2R-positive networks. The administration of TIP39 and an antagonist of the PTH2R as well as the investigation of mice that lack functional TIP39 and PTH2R revealed the involvement of the PTH2R in a variety of neural and neuroendocrine functions. TIP39 acting via the PTH2R modulates several aspects of the stress response. It evokes corticosterone release by activating corticotropin-releasing hormone-containing neurons in the hypothalamic paraventricular nucleus. Block of TIP39 signaling elevates the anxiety state of animals and their fear response, and increases stress-induced analgesia. TIP39 has also been suggested to affect the release of additional pituitary hormones including arginine-vasopressin and growth hormone. A role of the TIP39-PTH2R system in thermoregulation was also identified. TIP39 may play a role in maintaining body temperature in a cold environment via descending excitatory pathways from the preoptic area. Anatomical and functional studies also implicated the TIP39-PTH2R system in nociceptive information processing. Finally, TIP39 induced in postpartum dams may play a role in the release of prolactin during lactation. Potential mechanisms leading to the activation of TIP39 neurons and how they influence the neuroendocrine system are also described. The unique TIP39-PTH2R neuromodulator system provides the possibility for developing drugs with a novel mechanism of action to control neuroendocrine disorders.

While the DILP producing IPCs of the brain secrete DILP2, 3, and 5, fat body produces DILP6. Identification of factors that influence dilp expression and DILP secretion has provided insight into the intricate regulatory mechanisms underlying transcriptional regulation of those genes and the activity of each peptide. Studies involving loss-of-function dilp mutations have defined the roles of DILP2 and DILP6 in carbohydrate and lipid metabolism, respectively. While DILP3 has been implicated to modulate lipid metabolism, a metabolic role for DILP5 is yet to be determined. Loss of dilp2 or adult fat body specific expression of dilp6 has been shown to extend lifespan, establishing their roles in longevity regulation. The exact role of DILP3 in aging awaits further clarification. While DILP5 has been shown associated with DR-mediated lifespan extension, contradictory evidence that precludes a direct involvement of DILP5 in DR exists. This review highlights recent findings on the importance of conserved DILPs in metabolic homeostasis, DR, and aging, providing strong evidence for the use of DILPs in modeling metabolic disorders such as diabetes and hyperinsulinemia in the fly that could further our understanding of the underlying processes and identify therapeutic strategies to treat them.The neuroendocrine architecture and insulin/insulin-like signaling (IIS) events in Drosophila, eight insulin-like peptides (DILPs) and one insulin receptor (DInR) are found. DILPs 1\u20138 have been identified mostly through their sequence homology to the mammalian insulin and the typical B-C-A domain structure as observed in mammalian insulin in the brain has provided a physiological link between those two major tissues governing nutrient sensing, metabolism, and aging pathway governs growth and development, metabolism, reproduction, stress response, and longevity. In Drosophila insulin-like peptide genes (dilp1\u20137) with diverse temporal and spatial specific expression patterns and several neurons in the brain constructs in their fat body similar to the levels observed in dSir2 RNAi flies , short neuropeptide F (sNPF) modulates metabolism and lifespan revealed an up-regulation of dilp1 and dilp2 mRNA as the result of sNPF overexpression accompanied by increased IIS in the periphery , a member of Drosophila E3 ubiquitin ligases and adaptor proteins, negatively regulates the expression of brain dilps. Neuronal and IPC-specific knockdown of dcbl results in up-regulation of dilps 2, 3, 5 whereas the Epidermal growth factor receptor (EGFR) signaling pathway mediates this regulatory effect of dCbl only on dilps 2 and 3. Thus, a likelihood of other mediators for dilp5 is speculated play a prominent role in regulating insulin secretion in \u03b2-pancreatic cells signaling -producing corpora cardiaca (CC) cells are neurosecretory cells that function to regulate metabolic processes in the fly (Rulifson et al., dilp2 overexpression strongly supported the notion that loss of DILP2 was responsible for the phenotypes (Rulifson et al., The first set of compelling evidence demonstrating the functional extent of DILPs in controlling growth, development, and glucose homeostasis was generated by the destruction of IPCs. Ablation of IPCs during the early larval stage results in severe developmental delay with a reduction of both cell numbers and body size accompanied by an increased level of circulating sugars suggesting a diabetic-related phenotype (Rulifson et al., daf-2, a gene encoding the insulin receptor homolog in C. elegans nearly doubled the lifespan of the organism (Kenyon et al., Drosophila homolog of the insulin receptor substrate CHICO similarly render cell non-autonomous effects in lifespan extension as the result of reduced IIS (Clancy et al., The role of IIS pathway in aging was first discovered when mutations of dilps and DILP2 possesses the highest homology to the mammalian insulin with a 35% identity in protein sequence (Brogiolo et al., dilp2 is associated with lifespan extension under several conditions. First, activation of dFOXO in the pericerebral fat body extends lifespan with an accompanied reduction in dilp2, but not in dilp3 or dilp5 mRNA levels (Hwangbo et al., dilp2 is associated with the extension of lifespan observed in those flies (Wang et al., dilp2 transcript levels, again indicating that the reduction of dilp2 expression was closely associated with extended longevity under those genetic conditions (Bauer et al., dilp2 expression and increased lifespan, direct modulation of dilp2 levels was needed to assess the causal relationship between dilp2 expression and lifespan control. To this end, surprisingly, while causing a severe reduction of dilp2 transcripts, targeted knockdown of dilp2 in IPCs did not result in any lifespan extension (Broughton et al., dilp3 and dilp5 expression was observed in those flies raising the possibility that a compensatory mechanism exists to modulate overall dilp expression in the IPCs. However, this compensatory increase in dilp3 and dilp5 expression could not completely account for the lack of lifespan extension in dilp2 knockdown flies as a similar increase of dilp3 and dilp5 transcripts was observed in long-lived dilp2 null mutant flies and increased dilp5 expression levels in long-lived dilp2\u20133 mutants (Gronke et al., dilp2 knockdown elicits additional genetic alterations neutralizing the effect on lifespan associated with reduced dilp2 transcripts. The extended lifespan measured in dilp2 null mutants, however, confirms a major role of DILP2 in longevity control. The absence of any change in lifespan in flies with a dilp3 deletion is intriguing as both dilp2 and dilp5 transcript levels are lowered in those flies (Gronke et al., dilp transcript levels and lifespan effects in dilp2, dilp2\u20133, and dilp3 null mutants requires further clarification with measurements of DILP peptide levels as possible compensatory mechanisms to modulate IIS and lifespan regulation. An involvement of DILP3 in longevity control is worth further investigation, however as dilp3 transcript levels appeared to be specifically reduced in long-lived flies with increased mitochondrial uncoupling in adult IPCs (Fridell et al., dilp5 null mutant appeared to have no effect on lifespan under standard diet (Gronke et al., dilp5 levels are moderated in DR-mediated lifespan extension (Min et al., dilp6 loss-of-function mutation neither had any effect on adult Drosophila survival nor on any compensatory increase in the expression of other dilps (Gronke et al., dilp6 in the adult abdominal fat body significantly extends lifespan in females in a diet-dependent manner and negatively affects expression of dilp2 and dilp5, whereas a modest effect in survival is observed when dilp6 is expressed in the pericerebral fat body. This study also shed light on the fact that the longevity effect of dFOXO when overexpressed in the pericerebral fat body requires dilp6 (Bai et al., dilp mutants has confirmed lifespan extension as the result of dilp2 deficiency suggesting a major role of DILP2 in modulating IIS. On the other hand, targeted expression of dilp6 in the adult fat body results in profound longevity and metabolic consequences that underlies its role in lifespan regulation.A significant amount of interest has been bestowed upon DILP2 as its transcript is most abundantly expressed among all dilp mutants have paved the way. IPC ablated flies exhibit high levels of trehalose, lipid and glycogen stores, accompanied by increased stress resistance (Broughton et al., dilp2 loss-of-function mutant with no change in lipid or glycogen levels (Gronke et al., dilp 1\u20134 loss of function mutants were starvation resistant recapitulating the role for dilp2 in starvation resistance (Gronke et al., dilp2 null mutants nor dilp 2\u20133, 5 deletion mutants, created by homologous recombination, were resistant to starvation (Gronke et al., dilp2 null mutants. A putative role for DILP2 in response to oxidative stress was discovered in the context of JNK signaling upon oxidative stress where dilp2 expression is repressed in IPCs (Wang et al., dilp2 RNAi hypomorphs (Broughton et al., dilp2 loss-of-function mutants (Gronke et al., dilp6 over expression in the abdominal fat body exhibit metabolic phenotypes reminiscent of those seen as a consequence of reduced IIS (Bai et al., dilp6 loss-of-function mutants only had high stored lipid levels revealing its specific role in lipid storage (Gronke et al., To aid a better understanding of the significance of DILP2 and DILP6, physiological alterations that accompanied lifespan extension in respective dilp3 or dilp5 single mutants were neither resistant to starvation or oxidative stress nor was there any change in their trehalose, glycogen, or lipid levels (Gronke et al., dilp3 overexpressors play a role in regulating triglyceride levels (Varghese et al., Unlike DILP2 and DILP6, an involvement of DILP3 and DILP5 in any physiological feature that plays a part in lifespan regulation has not been identified. Drosophila. While the exact molecular mechanisms behind DR-mediated lifespan extension are yet to be completely elucidated, several molecular pathways have emerged as important players involved in DR responses (Narasimhan et al., C. elegans, depending upon the methods of DR, lifespan extension associated with DR is largely independent of IIS (Kaeberlein et al., Drosophila (Clancy et al., chico mutants did not respond to optimal DR for additional lifespan extension indicating an overlap between IIS and DR (Clancy et al., dFOXO mutants remained sensitive to DR thus suggesting that DR acts independently of IIS (Min et al., Drosophila in order to reconcile discrepant findings as well as pinpoint a role of IIS in DR (Tatar, Through dilution of nutrient content, DR is a robust intervention that has been shown to extend lifespan in R Tatar, .Drosophila are shown to extend lifespan with changes in dilp5 mRNA levels but not dilp2 or dilp3 levels (Min et al., dilp5 mRNA and DILP5 protein levels are down-regulated in wild type flies under a yeast DR diet where only yeast is diluted while keeping carbohydrate levels constant (Broughton et al., There is emerging evidence on the role of IPCs in lifespan extension through DR, as those neurosecretory cells appear to respond to nutrient changes (Broughton et al., dilp5 knocked down by a UAS-dilp3RNAi construct that repressed expression of dilps 2, 3, and 5 and blocked the nutrient-dependent expression of dilp5, exhibited a normal response to DR under a yeast DR regime implying that DR-mediated lifespan extension works independently of DILP5 (Min et al., dilp6 in the fat body lowers dilp2 and dilp5 expression as well as the respective hemolymph peptide levels, the lifespan of dilp6 overexpressors was similar to the controls under a yeast restricted diet corroborating with the evidence that DR works independently of dilp5 and DILP5 (Bai et al., Flies with dilp5 null mutant flies that displayed a normal DR response also exhibited a compensatory up-regulation of dilp2 mRNA when raised on food with high yeast concentration while dilp3 mRNA levels were up-regulated in these flies raised on food with relatively low yeast concentration (Gronke et al., dilp5 loss-of-function flies raised on yeast DR diet. Supporting evidence for the involvement of DILPs in DR, if not a direct role, was presented when dilp 2\u20133, 5 deletion mutant flies (Gronke et al., per se but whose activity has shown to modulate DR response when over-expressed (Giannakou et al., dilp5 is modulated under DR, this change in expression could simply be a response associated with dietary alterations but does not trigger the longevity effect of DR. Further clarification is required to definitively assign a physiological role of DILP5, if any, in DR response.However, Drosophila homolog of IGF-binding protein, Imp-L2 is shown to bind to DILP2 (Honegger et al., dilps have confirmed that loss of dilp2 and over-expression of dilp6 is sufficient to extend lifespan (Gronke et al., Drosophila as a model to study cross talk between the nutrient sensing fat body and the neurosecretory IPCs has shed significant insight into a systemic control of DILP activities as the result of communication between those two tissues tightly associated with metabolism. The studies highlighted in this review have underscored the importance of measuring DILP levels in order to substantiate and validate their functional significance. Specifically, measuring circulating DILPs in the hemolymph should provide most relevant assessment on secreted DILP levels and their systemic effects (Bai et al., DILPs are involved in a myriad of physiological processes ranging from growth (Brogiolo et al., dilps 1\u20135 mimics phenotypes seen in type 1 diabetes (Rulifson et al., dilp levels in modeling type 2 diabetes (Musselman et al., dilps in Drosophila, metabolic disorders such as diabetes, hyperinsulinemia, or those affecting glucose homeostasis can be modeled in this genetic organism. These approaches will likely further characterize the molecular mechanisms behind these disorders, discover drug targets, and screen potential therapeutic modes to treat these disorders. Apart from disease models, emerging research has revealed an involvement of DILPs in stem cell biology including stem cell proliferation (LaFever and Drummond-Barbosa, dilp8 in tumor eye discs that responds to signals from peripheral tissues to mediate their growth and development has further strengthened Drosophila as a model for investigating mechanisms underlying inter-organ communication and demonstrated a role for DILP8 in cancer biology (Garelli et al., Drosophila through diverse mechanisms that are being unraveled.Ablation of IPCs or deletion of The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "This study evaluated the potential of the NAVIGATOR (Applied Physiology) haemodynamic monitor to improve consistency of cardiovascular assessments amongst ICU members with different levels of expertise and experience.n = 20) post cardiac surgery were monitored by NAVIGATOR to display heart efficiency (Eh), mean systemic filling pressure (Pms) and vascular resistance (SVR) against targets for mean arterial pressure and cardiac output set by the clinical team.

This paper reports preliminary data from the first four months after the implementation of the standardized data collection protocol.The University of Minnesota Institutional Review Board and State of Washington Institutional Review Board approvals were obtained for this study. All local public health agencies in Washington State were invited to a statewide training on the data collection system (September 2010) and to participate in the data collection starting November 2010. The data collection period for this study ended in February 2011. Visit reports were submitted to State of Washington Department of Health CSHCN officials for program evaluations by 25 of the 35 local agencies during this time period.

Problems are uniquely identified by distinctive definitions and signs and symptoms (s/sx). The Intervention Scheme is used for addressing the problems which are described using the four-level Intervention Scheme.

The use of the CSHCN visit reports will generate large data sets that will enable further evaluation of the effectiveness of PHN interventions for these problems. Previous studies have described intervention tailoring and effectiveness for high risk families \u201321. Furt The use of the Omaha System enabled the aggregation of standardized CSHCN data for program evaluation. Assessments and intervention data from 25 of 35 local health jurisdictions were included in this study. The 127 visit reports were submitted to the Department of Health on the paper visit report forms. Data from electronic documentation of CSHCN assessments and interventions were not included in this study but will be available in the future. The interoperability of electronic systems continues to be a challenge. It is essential for state and local health jurisdictions, software vendors, and policy makers to work together to achieve the goals of standardized, interoperable systems to support uniform data collection for program evaluation and research.The results of this study will be used by the Washington State CSHCN program to focus nursing activities on the problems most likely to be encountered by PHNs serving the CSHCN population. Additionally, these results will be used to further refine the program evaluation process.National, state, and local officials have a responsibility to develop, support, and maintain CSHCN programs , 22. Pub With all research using large observational data sets, limitations of the data include observer bias and fidelity to documentation procedures. While the sample of 127 clients from 25 local health jurisdictions demonstrates the feasibility of the approach, bias toward submitting forms for clients with the greatest need may exist. This limitation is supported by the PHN interpretation of the findings reported in Section 5.0. Therefore, alternative explanations for the findings must be considered. In this study, many of the local health jurisdictions started to use the Omaha System for the CSHCN at the beginning of the data collection period. Documentation quality was supported by peer training and the use of KBS rating guide supplements. However, no evaluation of documentation quality was included in the program evaluation protocols. Further research is needed to create quality assurance measures that can be implemented as an integral part of program evaluation.This study demonstrates the feasibility of a structured approach to case management, surveillance, and program evaluation for CSHCN using a standardized terminology. The use of the Omaha System facilitated uniform data collection of client assessments and services across 25 of 35 local health jurisdictions in the first four months of the evaluation. Preliminary findings suggest that critical needs existed among CSHCN in Washington State. In the future, larger data sets will be used to evaluate the quality of PHN services, inform public policy, and improve the health CSHCN and their families."} +{"text": "A number of studies have outlined mechanisms by which mycoplasma infection may promote allergic lung inflammation.

Advanced quantitative magnetic resonance imaging (MRI) techniques enable to explore in vivo the volume and microstructure of the cerebral cortex in ALS. We studied with a combined voxel-based morphometry (VBM) and magnetization transfer (MT) imaging approach the capability of MRI to identify the cortical areas affected by neurodegeneration in ALS patients. Eighteen ALS patients and 18 age-matched healthy controls were examined on a 1.5T scanner using a high-resolution 3D T1 weighted spoiled gradient recalled sequence with and without MT saturation pulse. A voxel-based analysis (VBA) was adopted in order to automatically compute the regional atrophy and MT ratio (MTr) changes of the entire cerebral cortex. By using a multimodal image analysis MTr was adjusted for local gray matter (GM) atrophy to investigate if MTr changes can be independent of atrophy of the cerebral cortex. VBA revealed several clusters of combined GM atrophy and MTr decrease in motor-related areas and extra-motor frontotemporal cortex. The multimodal image analysis identified areas of isolated MTr decrease in premotor and extra-motor frontotemporal areas. VBM and MTr are capable to detect the distribution of neurodegenerative alterations in the cortical GM of ALS patients, supporting the hypothesis of a multi-systemic involvement in ALS. MT imaging changes exist beyond volume loss in frontotemporal cortices. Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative disorder characterized by upper motor neuron (UMN) and lower motor neuron (LMN) degeneration The UMN involvement in ALS cannot be easily established based on the clinical ground because of the confounding effect of LMN involvement.

They were located in the superior, middle and inferior frontal gyri , in the supplementary motor area (AAL 20) and in the temporal lobe (AAL 85) . These rResults of the between group MTI analysis revealed that the MTr values were significantly lower in ALS patients than in the healthy controls in the following cortical regions: superior, middle and inferior frontal gyrus , gyrus cinguli , supplementary motor area , insula and temporal lobe .Results of the between group regional MTI analysis corrected for atrophy revealed that the MTr values were significantly lower in ALS patients than in the healthy controls in the superior, middle and inferior frontal gyri , in the gyrus cinguli , in the supplementary motor area , in the insula and in the temporal lobe .No cluster of significant association between atrophy or MTr changes and clinical scales was detected in the respective statistical maps.ALS is emerging as a multi-system disease involving several frontal-temporal structures beside motor structures and functions In order to compare the spatial distribution of atrophy and MTr changes in ALS we adopted in the present study a voxel based approach of MT data Since a region specific MTr decrease in the sensory motor cortex is observed with advancing age Although we do not know the exact meaning of the reduced MTr in the cerebral motor-related and extra-motor cortex of ALS patients, the rate of MT effect depends on the surface chemistry and the biophysical dynamics of the macromolecules, as well on the concentration of macromolecules and water The neuronal loss and degeneration in the V layer of the cortex into the precentral gyrus is considered the pathological hallmark of the UMN involvement in ALS In the present study the voxel-wise analysis of GM volume, MTr and MTr data corrected for regional atrophy failed to show any structural abnormality in the precentral gyrus of ALS patients. This result may reflect both the fact that the pathological changes in primary motor cortex of ALS patients are subtle On the other hand our and other studies showed clusters of atrophy and MTr changes in motor-related area. Clusters of decreased MTr independent of cortical atrophy were observed in the premotor cortex particularly in the superior, middle frontal gyri pertaining to the fronto parietal circuit At multimodal image analysis, the MTr decrease in prefrontal and temporal cortex of our ALS patients survived correction for local atrophy indicating that the microstructural changes exist beyond the areas of cortical atrophy. This interpretation is supported by the observation that MTI can detect microstructural changes in cortical areas unaffected by atrophy also in patients with Alzheimer disease (AD) A longitudinal evaluation of VBM and MTr data could be a further fundamental step in evaluating their spatial and temporal relationship in the progression of motor and cognitive functions in ALS and is currently under way.We recognize as main limitation of our work that we did not obtain a detailed neuropsychological profile of our patients. This hinders investigation of the relationship between behavioural and cognitive functions and regional volume or MTr of the cortical GM in specific brain structures VBM and MTI reveal regional atrophy and microstructural changes of the cerebral cortex in ALS involving not only motor-related areas but also frontotemporal cortices.MTr reduction occurs in non atrophic cortical areas suggesting that microstructural degenerative phenomena can extend beyond the tissue loss in ALS.Table S1Demographic and Clinical data.(DOC)Click here for additional data file.Table S2VBM results: clusters of cortical atrophy.(DOC)Click here for additional data file.Table S3MT Imaging results: clusters of reduced MT ratio.(DOC)Click here for additional data file.Table S4MT Imaging results: clusters of reduced MT ratio adjusted for atrophy.(DOC)Click here for additional data file."} +{"text": "A number of human diseases such as obesity and diabetes are associated with changes or imbalances in the gut microbiota (GM). Laboratory mice are commonly used as experimental models for such disorders. The introduction and dynamic development of next generation sequencing techniques have enabled detailed mapping of the GM of both humans and animal models. Nevertheless there is still a significant knowledge gap regarding the human and mouse common GM core and thus the applicability of the latter as an animal model. The aim of the present study was to identify inter- and intra-individual differences and similarities between the GM composition of particular mouse strains and humans.A total of 1509428 high quality tag-encoded partial 16S rRNA gene sequences determined using 454/FLX Titanium (Roche) pyro-sequencing reflecting the GM composition of 32 human samples from 16 individuals and 88 mouse samples from three laboratory mouse strains commonly used in diabetes research were analyzed using Principal Coordinate Analysis (PCoA), nonparametric multivariate analysis of similarity (ANOSIM) and alpha diversity measures. A reliable cutoff threshold for low abundant taxa estimated on the basis of the present study is recommended for similar trials.Distinctive quantitative differences in the relative abundance of most taxonomic groups between the examined categories were found. All investigated mouse strains clustered separately, but with a range of shared features when compared to the human GM. However, both mouse fecal, caecal and human fecal samples shared to a large extent not only representatives of the same phyla, but also a substantial fraction of common genera, where the number of shared genera increased with sequencing depth. In conclusion, the GM of mice and humans is quantitatively different (in terms of abundance of specific phyla and species) but share a large qualitatively similar core. Shifts in the composition, known as dysbiosis, of the human GM have in several studies been associated with diseases such as allergies Rodents are the mammalian model most extensively used to investigate the relationship between GM and health and disease. The reason for the popularity of mouse models is their well explored genetic and relatively close physiological similarity with humans and the ability to control a wide range of environmental factors which reduces variation in the baseline gut microbiota between individual study objects Lachnospiraceae family have been suggested as possible biomarkers to help predict predispositions to inflammatory bowel disease Many GM related disorders have been linked with bacterial dysbiosis on a higher taxonomic level proving the usefulness of sequencing the GM to e.g. phylum and family level. For example, Turnbaugh et al. showed that a switch from a low fat to a high fat, high sugar diet in mice, which was associated with obesity, lowered the Bacteroidetes/Firmicutes ratio in the gut within one day However, the usefulness of mice models for such studies would to a large extent also depend on similarities in their GM profiles at genus or species level with humans. The aim of the present study was therefore to demonstrate inter- and intra-individual differences and similarities between the GM composition of three laboratory mouse strains commonly used in research in chronic inflammatory diseases with those of humans based on more than 1.5 million high quality sequences of partial 16S rRNA gene verified with tag-encoded 454/FLX Titanium (Roche) pyro-sequencing.A total of 88 mice and 128 human GM profiles determined using tag-encoded 16S rRNA gene 454/FLX Titanium (Roche) pyro-sequencing were included in the study . All samAll animal experiments were carried out in accordance with the Council of Europe Convention European Treaty Series (ETS) 123 on the Protection of Vertebrate Animals used for Experimental and Other Scientific Purposes, and the Danish Animal Experimentation Act (LBK 1306 from 23/11/2007). The study was approved by the Animal Experiments Inspectorate, Ministry of Justice, Denmark.Human specimens used in this meta-analysis come from the independent study that was approved by The Scientific Ethics Committee of Capital Region, Denmark (reference H-4-2010-137). Written informed consent was obtained from volunteers prior to recruitment.http://www.drive5.com/usearch/). The representative sequences from each cluster were aligned with pyNAST (http://qiime.org/pynast/) and subjected to the Ribosomal Database Project (RDP)-based 16S rRNA gene annotation. For intra-individual assessment all mouse and 16 human samples from the control group were subsampled to an equal number of reads per individual (4500 reads per sample which constitutes to 85% of the second most indigent sample in the dataset). For inter-group comparison the reads were merged according to host (mouse strain/human) and subsampled to an equal number of sequences per category, respectively 80000 reads for mice strains comparisons and 600000 reads for similarity assessment between mice and humans. Both numbers constitute approximately 85% of the least numerous category. Alpha diversity measures such as rarefaction curves based on the estimated species number (97% sequence identity threshold), Chao1 and Shannon indexes were calculated for OTU tables that were unified to 4000 (first most indigent sample) sequences per sample.The dataset was analyzed using the Quantitative Insight Into Microbial Ecology (QIIME) open source software package In order to investigate the influence of the sequencing method into variance between categories, which is caused mostly by the low abundant taxa, a set of 16 samples each sequenced in 4 independent runs were compared within their quadruplicates. A set of 1000 subsampled OTU-tables was generated for each sample (3000 reads per sample). Low abundant taxa were removed until taxa similarity of all replicates within a given sample crossed 99%. An average, minimum cutoff value was therefore calculated based on 16000 subsampled OTU tables using an in-house Matlab (Mathworks) script.Principal Coordinate Analysis (PCoA) plots were generated with the Jackknifed Beta Diversity workflow based on 10 distance metrics calculated using 10 subsampled OTU tables. The -e value (number of sequences taken for each jackknifed subset) was set to 85% of the sequence number within the most indigent sample. Analysis of similarities (ANOSIM) was used to evaluate group differences using weighted and unweighted uniFrac distance metrics that were generated based on rarefied (4500 reads per sample) OTU tables. The relative distribution of the GM genera registered in 88 mouse and 16 human samples was calculated for unified, summarized at the genus level OTU tables.http://metastats.cbcb.umd.edu). From each group 14 samples were randomly chosen and combinations of group pairs were tested using 1000 permutations . The relationship between sequencing depth and shared GM, classified into phylum and genus level, between mice and humans was plotted based on multiple subsampled OTU tables composed of two categories collecting 794988 human and 714440 mouse GM 16S rRNA gene reads. Simulation of each sequencing depth was repeated 100 times and an average proportion of shared taxonomic groups between the two categories were calculated (abundance threshold for unshared taxa\u200a=\u200a0.19%).Differences in taxa abundances at phylum and genus level between categories were verified with Metastats (http://www.cytoscape.org/).A network presenting shared genera between categories was prepared for normalized OTU tables (600000 reads per category) after filtering the low abundant OTUs (abundance threshold for unshared taxa\u200a=\u200a0.19%) using the make_otu_network.py script (QIIME). The visualization of the OTU-networks was performed with an open source platform \u2013Cytoscape yielded 1753858. After removing chimeric sequences a total of 1509428 reads remained, meaning that the ChimeraSlayer algorithm Alpha diversity assessment using rarefaction curves revealed that the fecal GM of the BALB/c mice is the most rich in OTUs (species-level). The average Chao1 index calculated for 4000 reads per sample was 2.5\u20135 times higher in this group compared with other groups . SpeciesobLep/J groups where age was the only varying factor were only partially separated . The three remaining mouse strains were either devoid of bacteria from this phylum, or the bacteria were below the detection limit.All reads used in this study were classified into 9 phyla after applying the abundance threshold (0.19%), with one phylum noted as unclassified . GeneralAlistipes (12%), while in human specimens \u2013 Roseburia (12%) and unclassified genus representing the Clostridiales order (10%) were the dominating genera.The relative abundance of genera depicted for all samples individually shows explicit alterations between studies with the human specimens being the most conspicuous category . In totaMetastats analysis revealed widespread differences in the bacterial relative abundance at both phylum and genuobV-Lep/J pups and the NOD group was not detected in the adult B6. obV-Lep/J counterparts (examined in the age of 16 weeks), nor in any of the BALB/c mice. The Akkermansia genus which is the only representative group of the Verrucomicrobia phylum, was therefore the reason of discrepancies on both the phylum . The similarity of the collective mouse and human microbiomes without the abundance threshold was correspondingly 40% and 57% lower at the phylum and the genus level comparedIn Laboratory mice are commonly used as experimental models for diseases such as diabetes Qualitative and quantitative-based analysis of the three mouse strains fecal GM compared with the mice caecal and human fecal GM (PCoA and ANOSIM) disclosed significant separation of all microbial profiles. The composition of the GM has previously been shown to be influenced by multiple factors including environment and host genetics Diet is an environmental factor known to strongly influence GM composition Early priming of bacterial colonization during early life may also influence GM and immunity later in life Lastly, for adult humans and mice the influence of age on the GM profiles seems to be minor as neither human samples collected from patients at different age (18\u201350 years) nor NOD mice analyzed at different ages (14\u201330 weeks) clustered according to age. This supports the high level of GM composition stability in adult individuals which was previously documented among humans and mice Although innovations in high throughput sequencing techniques offer insight into microbial communities at an hitherto up-preceded level of details one need to be aware of constrains that comes with it, for example: sequencing depth, reads error rate and length or analysis methods In the present study the Firmicutes fraction was more abundant than the Bacterioidetes in most fecal and caecal samples, except for the BALB/c fecal samples, which showed an inverted proportion of these two phyla. Human fecal samples had relatively more Firmicutes and less Bacteriodetes compared to most mouse fecal and caecal samples. This is in accordance with earlier studies reporting that the majority of bacteria in the gut are members of these two phyla and that in mice the Firmicutes fraction seems to be much larger than the Bacteriodetes fraction As seen from Prevotella genus has been found to be inversely correlated with body weight gain, cholesterol accumulation, insulin resistance and diet-induced adiposity Odoribacter genus which relative abundance was recently shown to be increased in the caecum of mice exposed to grid floor induced stress obLep/J group that on the other hand were lacking members of the Akkermansia genus.

Among these 9 genera were Faecalibacterium from the Ruminococcaeae family and Asteroleplasma from phylum Tenericutes that both have been suggested as possible indicators of a healthy human GM since disturbances in the relative distribution of common species from these genera have been linked with the etiology of Crohn\u2019s disease (CD) and ulcerative colitis (UC) Megasphera genus was also unique for humans not being detected in any of the three mouse strains.

The main function of inflammation is to resolve the infection or repair the damage and return the body to a state of homeostasis. Acute inflammation can induce signals that result in two main functions: 1) initiation of an inflammatory cascade that helps limits the infection and 2) activation of the immune response. In this study we determined the impact of the nature and magnitude of acute inflammation on the host anti-tumor activity against Ehrlich Ascites cancer cell (EAC) line as a model system which forms either peritoneal ascites upon intraperitoneal injection.Different inflammatory signals, including agonists for toll-like receptor (TLR) 2 (zymosan) and TLR3 agonist (poly (I:C) or its clinical grade Hiltonol\u00ae), complete Freund's adjuvant (CFA), and incomplete Freunds Adjuvant (IFA), and BCG from Bacillus calmatte (TLR9 agonist) were used to induce acute inflammation 1 day after i.p. challenge with EAC.We found that Hiltonol\u00ae, poly (I:C), IFA, CFA, and BCG induced inflammatory cells associated with anti-tumor activity that resulted in significant decrease in the tumor growth measured by the total number of tumor cells after 7 days of tumor challenge.

The aim of the study was to assess: the relationship between angiogenic factors, their soluble receptors and organ dysfunction associated with DIC precipitated by severe trauma; and the effects of DIC-induced platelet consumption, thrombin generation and tissue hypoxia on the expression of these factors and receptors.Fifty-seven patients with severe trauma were divided into two subgroups: 30 DIC patients and 27 non-DIC patients. The serum levels of angiogenic factors were measured on admission (day 1), day 3, and day 5. We compared serum levels of these angiogenic factors between with and without DIC groups and evaluated their predictive value for organ dysfunction and outcome.DIC patients showed higher Sequential Organ Failure Assessment (SOFA) scores, soluble fibrin and lactate levels. The serum levels of VEGF, Ang1, and the sTie2 levels were lower in the DIC patients than the non-DIC patients. The serum levels of sVEGFR1, Ang2 and the Ang2/Ang1 ratio in the DIC patients were higher than in those without DIC. The sVEGFR2 levels showed no statistically significant difference between the patients with and without DIC. The levels of sVEGFR1, Ang2 and the Ang2/Ang1 ratio correlated with the SOFA score. In particular, sVEGFR1 and Ang2 were independent predictors of an increase in the SOFA score. The lactate levels independently predicted increases in the levels of sVEGFR1 and Ang2 and platelet consumption also independently predicted the increase in Ang2 levels in severe trauma patients with DIC.Angiogenic factors and their soluble receptors, particularly sVEGFR1, play pivotal roles in the development of organ dysfunction in DIC associated with severe trauma. The DIC-induced tissue hypoxia and platelet consumption plays crucial roles in inducing sVEGFR1 and Ang2, and in determining the prognosis of the severity of organ dysfunction."} +{"text": "Molecular epidemiologic findings suggest an ancient focus of TB. Mycobacterium tuberculosis in India is largely unknown. A collection of 91 isolates originating from 12 different regions spread across the country were analyzed by genotyping using 21 loci with variable-number tandem repeats (VNTRs), by spoligotyping, by principal genetic grouping (PGG), and by deletion analysis of M. tuberculosis\u2013specific deletion region 1. The isolates showed highly diverse VNTR genotypes. Nevertheless, highly congruent groupings identified by using the 4 independent sets of markers permitted a clear definition of 3 prevalent PGG1 lineages, which corresponded to the \"ancestral\" East African\u2013Indian, the Delhi, and the Beijing/W genogroups. A few isolates from PGG2 lineages and a single representative of the presumably most recent PGG3 were identified. These observations suggest a predominance of ancestral M. tuberculosis genotypes in the Indian subcontinent, which supports the hypothesis that India is an ancient endemic focus of TB.Although India has the highest prevalence of tuberculosis (TB) worldwide, the genetic diversity of Mycobacterium tuberculosis, its main causative agent, is widely disseminated and is one of the most successful human pathogens today, with 2 billion persons infected. Most of the disease's effects are now concentrated in countries with few resources; India has the highest number of cases (Tuberculosis (TB) in humans has been described since ancient times. M. tuberculosis of genetic elements named mycobacterial interspersed repetitive units (MIRUs) were used to assess consistency of the genetic relationships obtained by VNTR typing and spoligotyping at a broader evolutionary level. SNPs in the katG and gyrA genes classify M. tuberculosis isolates into 3 principal genetic groups (PGGs) thought to have evolved sequentially from group 1 to group 3 according to the previously described method . MIRU-VNTR profiles were compared to each other by using the neighbor-joining algorithm.

NMUR1 is expressed predominantly at the periphery, while NMUR2 in the central nervous system. Elements of the NMU/NMS and their receptors network are also expressed in the HPA axis and progress in molecular biology techniques provided new information on their actions within this system.

Of particular relevance is the local production of autoantibodies such as rheumatoid factor and anti-citrullinated protein antibodies in the inflamed synovial tissue. The mechanisms underlying break of B cell tolerance and local autoantibody production remains poorly understood. This study was conducted in order to identify cellular and molecular pathways implicated in RA-specific humoral autoimmunity.Synovial tissue samples were obtained by arthroscopy from untreated individuals with RA (n=33) and inflammation matched SpA controls (n=58). Gene expression profiling was performed on tissue samples of patients with established arthritis using 44K Whole Genome Human microarrays (Agilent). Top differentially expressed genes were validated on three independent cohorts by Taqman based RT-qPCR and immunohistochemistry. Collagen-induced arthritis (CIA) and Experimental autoimmune encephalomyelitis (EAE) experiments were conducted using Bob1 knockout mice and their littermate controls.\u2212/\u2212 mice were fully resistant to CIA induction compared to their wild-type littermates. This remarkable protection from CIA is explained by failure to produce pathogenic anti-collagen autoantibodies in the absence of Bob1. In contrast, Bob1\u2212/\u2212mice were susceptible to MOG protein induced EAE and incidence and severity of clinical disease were not altered in these mice comparing to wild-type littermates, suggesting that absence of Bob1 does not impact on antigen-presentation/costimulatory capacity of B cells.Microarray screening for genes differentially expressed in the inflamed synovium, the key target of the disease process in RA, revealed a prominent and disease-specific B cell/plasma cell signature with the B cell-specific transcriptional co-activator Bob1 and its transcriptional target BCMA among the most upregulated genes. Validation by RT-qPCR on two independent cohorts representing early and established arthritis confirmed microarray data and demonstrated elevated expression of Bob1 and BCMA not only in established RA, but also at the early phase of the disease. Quantitative evaluation of immunohistochemical stainings of synovial tissue with monoclonal antibody for Bob1 revealed significant increase in Bob1 positive cells in RA synovium (p<0.01). Next we determined whether lack of functional Bob1 modifies disease onset or severity in CIA. Interestingly, the results showed that Bob1The specific increase in Bob1 expressing cells in RA synovitis and the resistance of Bob1-defecient mice to development of CIA indicate that Bob1/BCMA axis may contribute to humoral autoimmunity in RA.

In our experiments, electrical stimulation produced a wide variety of effects depending on stimulation frequency, intensity, and the drug concentrations used. At stimulation intensities near threshold we were able to produce phase advances and delays that resolved within a single step cycle. During these single-cycle alterations we observed different effects after stimulating dL2 and dL5. Stimulation of dL2 during ipsilateral extension typically produced an early onset of the next flexion and termination of current extension in the ipsilateral activity with or without rhythm disturbances on the contralateral side of the cord (subject to drug concentrations and stimulus intensity). These disturbances represented a true phase resetting characterized by a full flexor phase expression independent of ending the stimulation producing the disturbance. In contrast, stimulation of dL5 often produced a complex bilateral effect starting from a brief activation of ipsilateral extension (for the stimulus duration) with a corresponding reduction in the flexor activity followed by a reactivation of ipsilateral flexor activity (a full second burst that could represent a rebound evoked by end of stimulation) and then by an enhanced next extensor burst.

A new paradigm of targeted therapies holds the most promise for the future, making identification of tumor-specific therapeutic targets of prime importance. ERBB2/HER2, best known for its role in breast cancer tumorigenesis, can be targeted by two types of pharmacological manipulation: antibody therapy against the extracellular receptor domain and small molecule compounds against the intracellular tyrosine kinase domain.

The discovery of primary activating mutations and the emergence of acquired secondary mutations represent sophisticated challenges for effective treatment approaches.

In an adaptive response, bacteria have evolved systems to acquire the metals in the face of this competition while effluxing excess or toxic metals to maintain a bioavailability of transition metals that is consistent with a particular inorganic \u201cfingerprint\u201d under the prevailing conditions. This review highlights recent biological, chemical and structural studies focused on manganese (Mn) acquisition and homeostasis and connects this process to oxidative stress resistance and iron (Fe) availability that operates at the human host-pathogen interface.Pathogenic bacteria acquire transition metals for cell viability and persistence of infection in competition with host nutritional defenses. The human host employs a variety of mechanisms to stress the invading pathogen with both cytotoxic metal ions and oxidative and nitrosative insults while withholding essential transition metals from the bacterium. For example, the S100 family protein calprotectin (CP) found in neutrophils is a calcium-activated chelator of extracellular Mn and Zn and is found in tissue abscesses at sites of infection by The most abundant transition metals in humans are iron (Fe) and zinc (Zn) , Mn(IV) and Mn(V)] and is most strongly linked to oxidative stress resistance mediated by Mn superoxide dismutase (Mn-SOD) . This is generally expressed in nmol or ng of each metal per mg total protein and is readily measured by inductively coupled plasma mass spectrometry (ICP-MS) of acid-solubilized cells. A remarkable aspect of the inorganic fingerprint relevant to this discussion is the fact that the total Mn:Fe ratio varies by over seven orders of magnitude when various single-celled organisms are compared with one another when grown in the presence of oxygen and Fe(II), if left unregulated metal ions to the exclusion of all others or hydrogen peroxide (H2O2) atoms from enzymes harboring mononuclear Fe and 4Fe-4S cluster cofactors dissociation, essentially analogous to that which occurs in the peroxide sensor Fe-PerR H2O2 induces the OxyR regulon which includes genes encoding a manganese import pump MntH and the DNA binding iron-scavenging protein Dps .Manganese as a micronutrient is critical to the viability and virulence of many Gram-positive and Gram-negative bacterial pathogens .

Another example of this type of cofactor replacement is the iron sequestration protein, Dps, in Kineococcus radiotolerans via cofactor substitution in the oxidative stress response functions as an antioxidant through a combination of enzymatic degradation of oxidants by Mn-SOD and other Mn(II)-containing enzymes, nonenzymatic degradation of oxidants by LMW-Mn complexes, and metalloenzyme cofactor substitution to prevent Fe-induced peroxide chemistry and subsequent enzyme inactivation Figure .

This is also true from the perspective of fundamental inorganic chemistry since Mn(II) complexes will tend to be far less thermodynamically stable than \u201cisostructural\u201d Zn(II) complexes Figure Waldron.

For example, the S100A7 homodimer limits growth and invasion at epithelial surfaces through chelation of Zn(II) . One simple explanation is that more resistant bacteria express Mn(II) uptake systems that possess a higher affinity than CP for Mn(II) and thus will compete more effectively with CP for extracellular Mn(II). This requires knowledge of the structure and Mn(II) and Zn(II) binding affinities of CP. Initial studies established that a single S100A8/S100A9 heterodimer is capable of binding two molar equivalents of transition metal, designated S1 and S2; however, while Zn(II) could fill both sites, Mn(II) could fill only one with high affinity (S1) which is well-modeled in metal binding experiments as two functionally independent heterodimers as a competitor ligand for Zn(II) revealed KdZn1 = 0.13 nM and KdZn2 = 185 nM (\u2013Ca) and KdZn1 \u2264 0.01 nM and KdZn2 \u2264 0.24 nM (+Ca) Mn(II) site conforming to octahedral coordination geometry site, thus likely connecting Mn(II) sequestration to the biological activity of CP. Although CP may have a lower affinity for Mn(II) than bacterially encoded SBPs transport into the cytoplasm with significantly higher affinity (\u2265100-fold), a finding consistent with the Irving-Williams series and Fe(II) can influence Mn(II) acquisition and intracellular Mn(II)-dependent metalloregulation of transcription. For example, Zn(II) has been shown to inhibit Mn(II) uptake by binding irreversibly to s Figure - or Mn(II)-specific metal-sensing repressor -MntR and two related Fur family members, the peroxide sensing, Fe(II)-binding PerR levels to rise to a level sufficient level to fill the mutant PerR regulatory site with cognate Fe(II) and Mn(II) homeostasis systems may well be more relevant to bacterial cell physiology and pathogenesis than is Zn(II)-Mn(II) crosstalk. These two metals lie at the same weakly competitive end of the Irving-Williams series and the Fe:Mn ratio might be considered a reporter of microbial lifestyle, capable of altering the altering the resistance of an organism to ROS -specific in vivo. Remarkably, this Fe(II)-specificity is lost in a perR mutant strain. Here, the combined impact of increasing Fur concentrations and intracellular Mn(II) levels relative to Fe(II), leads to conditions where Fur binds Mn(II), which in turn, leads to inappropriate Mn(II)-mediated repression of the fur regulon, including genes responsible for Fe(II) uptake. Thus, PerR may directly impact Fe(II) homeostasis by modulating Fur levels in response to a change in the Mn:Fe ratio, i.e., that which might occur under conditions of high Mn(II) and Fe(II)-deplete conditions :Fe(II) ratio :Fe(II) ratios under conditions of low iron is also critical to virulence in sepsis models effluxer, MntE, that is required for virulence -Mn(II) crosstalk influences bacterial pathogenesis is not firmly established, a number of recent studies suggest that maintenance of an optimal Mn(II):Fe(II) ratio can impact the virulence of pathogenic bacteria.

Loss of PTEN function results from several genetic mechanisms including small scale PTEN gene mutations , allelic loss at chromosome 10 and epigenetic silencing via hypermethylation of the PTEN promoter region. PTEN geFurther complicating the situation, the frequency of loss of PTEN expression increases from progression from normal colonic mucosa to adenoma, primary CRC and ultimately metastasis. The resClearly the role of PTEN is more complex than KRAS gene mutation where a single identifiable mechanism (activating mutation), largely concordant between primary and secondary tumours, confers near complete resistance to anti-EGFR MoAbs. Understanding this complexity is central to interpreting the current literature relating to PTEN and its potential role as a predictive biomarker. Recently reported cohorts of mCRC patients receiving anti-EGFR MoAbs have used PTEN loss of IHC expression to report loss of PTEN function. While this represents the functional outcome of several genetic mechanisms of PTEN loss, IHC relies on subjective interpretation and has the potential for inter reporter variation. Furthermore there is variability over the definition of 'loss of PTEN\u2019 based on IHC scoring. In the largest cohort of mCRC patients, PTEN loss was defined as no staining in any cells at any intensity, while oOur group undertook an analysis of PTEN status in the AGITG MAX study of mCRC patients to identify the rate of inter-observer variability in IHC assessment and the rate of discordance between IHC and PCR assessment of PTEN status.The MAX study design and eligibility criteria have been reported previously.The primary objective of this Phase III randomized trial was to evaluate the effect of adding bevacizumab to capecitabine (with or without mitomycin C) on progression free survival (PFS) among patients receiving first line chemotherapy for mCRC. Four hundred and seventy-one patients were enrolled between July 2005 and June 2007. We have used the TaqMan\u00ae Copy Number Assay to assess for PTEN allelic loss and have previously reported that loss of PTEN copy number was not prognostic nor predictive of outcome in the MAX trial cohort. In thisFormalin-fixed, paraffin-embedded (FFPE) samples of tumor tissue from archival specimens collected at the time of diagnosis were retrieved from storage at hospital pathology departments. For Copy Number PCR, genomic DNA was extracted from FFPE tissue sections with the use of the QIAamp DNA FFPE tissue kit . Manual micro-dissection was performed on samples with less than 80% malignant cells when visualized by microscopy. The same tissue blocks were used to make tissue microarrays (TMAs) and were assessed for PTEN expression by IHC. Researchers who assessed PTEN IHC expression were blinded to the PCR results.Immunohistochemical staining was carried out on TMAs using the PTEN monoclonal antibody 6H2.1 that has been used previously-36.

The assay is a duplex PCR for the PTEN gene and the reference gene, RNaseP , set up according to the supplier\u2019s protocol and run on the Rotorgene 6000 real time PCR instrument . The results are calculated as a ratio relative to a 2-copy control using the 2-\u2206\u2206Ct method (Rotorgene software), and multiplied by 2 to give the copy number. We tested DNA from colon cancer cell lines to determine the reproducibility of the assay and to select cell lines to use as copy number controls. HT29 (ATCC) is known to have 3 copies of chromosome 10 as determined by spectral karyotyping and comparative genomic hybridization[The PTEN TaqMan\u00ae copy number assay was performed using 10 ng DNA in quadruplicate PCR. The primers provided in the assay were entirely within exon 9 of dization. For theFifty-nine tumor specimens were analysed for loss of copy number by Taqman\u00ae and for loss of protein expression by IHC. Eight samples were found to contain no tumor tissue and were excluded from further analysis..Two blinded pathologists assessed 51 specimens independently for PTEN protein expression with IHC. Pathologist JC assessed 29/51 (57%) as having PTEN expression loss, while pathologist AR assessed 17/51 (33%) as having loss of PTEN expression. Concordance between pathologists on final IHC assessment (PTEN loss/no loss) was 37/51 (73%), indicating in 14/51 (27%) of specimens there was discordance in the final assessment of IHC PTEN loss had \u22641.5 copy number and were thus classified as PTEN loss.\u00ae PCR concordance analysis. Fifteen specimens had PTEN loss on IHC of which 10 (67%) also had PTEN allelic loss on Taqman\u00ae PCR. Seventeen specimens had PTEN allelic loss on Taqman\u00ae PCR of which 10 (58%) had PTEN loss on IHC. Fifteen specimens had preserved PTEN on both IHC and Taqman\u00ae PCR analysis. Overall concordance between IHC and Taqman\u00ae copy number in PTEN loss assessment was 25/37 (68%) whether protein expression is reduced and whether such reduction confers a growth advantage is unknown. Sood et al. also demonstrated monoallelic PTEN dysfunction (by mutation or promoter methylation) resulted in loss of protein expression in only 38% of samples, while biallelic inactivation resulted in loss of PTEN expression in 80% of cases. Ali et In our cohort 25% of cases without PTEN allelic loss demonstrated complete absence of PTEN expression on IHC. These findings confirm alternative genetic mechanisms, beyond allelic loss, are responsible for loss of PTEN protein expression. Several authors have undertaken more comprehensive analysis of PTEN status on CRC specimens and provide an important insight into the often coexisting genetic mechanisms of PTEN dysfunction. Goal et al. demonstrated hypermethylation of the PTEN promoter region occurred in 10/132 (7.6%) sporadic CRC specimens, with a higher rate (19.1%) in microsatellite unstable CRCs. PTEN mutations coexisted in 4/10 (40%) of hypermethylated PTEN specimens. Eighty percent of patients with promoter hypermethylation had reduced (+1) or loss of PTEN protein expression and in the 3 cases of complete loss of PTEN staining, promoter hypermethylation coexisted with PTEN mutation or allelic loss. PerroneAlternatively, focusing on loss of protein expression at least represents the functional outcome of any such genetic insult. We have demonstrated the current limitations of IHC for this purpose. In our cohort, IHC assessment of PTEN loss by two pathologists was 33% and 57%, with overall concordance of 73%. As this was designed as a validation subset we did not ask the two pathologists to discuss the results that were not concordant, nor seek a further opinion, methods commonly described in papers reporting PTEN IHC aimed at reducing the apparent discordance rate. In all Overall the current literature highlight the difficulty in accurately measuring PTEN function to date; measurement of a single genetic insult, while minimizing inter-observer variability, does not capture the often coexisting mechanisms required for biallelic inactivation. The use of IHC, while potentially a better measure of PTEN function, is observer dependent and there remains a lack of consensus on optimal methodology and scoring.Given the limitations of PTEN assessment discussed here, it is not surprising reports of the predictive value of PTEN as a biomarker in CRC remain conflicting,17,27,31The lack of standardization in assessing loss of PTEN function appears to have contributed significantly to the conflicting results from retrospective cohort studies. Further elucidation of PTEN as a potential biomarker for colorectal cancer relies on defining PTEN loss of function and standardizing analytical methods and scoring systems. Future studies assessing PTEN function may be better served by obtaining a more comprehensive analysis of PTEN function by assessing PTEN mutation, hypermethylation of PTEN promoter, PTEN allelic loss and protein expression on each specimen. An alternative approach may be to explore improved methods of measuring reduced protein expression beyond IHC, given reduced or absent protein expression should reflect the functional outcome of PTEN loss irrespective of the genetic mechanism. Immuno-PCR may provide an option of combining the protein-specific capability of antibodies with the objective quantification of real-time PCR.

We propose that widespread postzygotic aneuploidization of selected brain areas is a mechanism for AD neurodegeneration. Such area-specific distribution of aneuploidy can be explained by the accumulation of aneuploid cells during postnatal life or abnormal selective pressure against non-aneuploid cells (3).

They are all extremely rare but are clinically important as they cause very significant day to day symptoms and carry a high risk of early death due to AA amyloidosis. With the exception of familial Mediterranean fever treatment was essentially ineffective until this century.The discovery in 2002 that specific IL-1 blockade completely prevented all symptoms in cryopyrin associated periodic syndrome (CAPS) transformed treatment of this rare genetic disease. Isolation of the responsible gene, NLRP3, followed by rapid advances in molecular biology and identification of the inflammasome has made it clear that CAPS is purely a disease of IL-1 dysregulation. These discoveries combined with the availability of specific anti IL-1 agents have resulted in new insights into the regulation of IL-1 beta production in humans and its long term consequences.IL-1 is now recognised to be an important mediator of inflammation in other inherited autoinflammatory diseases such as Familial Mediterranean fever (FMF), TNF receptor associated periodic syndrome (TRAPS), deficiency of IL-1 receptor antagonist (DIRA) and mevalonate kinase deficiency and has transformed patient prognosis and quality of life.

We obtained five mitochondrial and five nuclear markers (6.8 kb) from 37 taxa corresponding to 17 of the 21 known extant species of Agnotecous, and including several localities per species, and we conducted phylogenetic and dating analyses. Our results suggest that the diversification of Agnotecous occurred mostly through allopatric speciation in the last 10 Myr. Highly microendemic species are the most recent ones (<2 Myr) and current sympatry is due to secondary range expansion after allopatric speciation. Species distribution should then be viewed as a highly dynamic process and extreme microendemism only as a temporary situation. We discuss these results considering the influence of climatic changes combined with intricate soil diversity and mountain topography. A complex interplay between these factors could have permitted repeated speciation events and range expansion.Islands are bounded areas where high endemism is explained either by allopatric speciation through the fragmentation of the limited amount of space available, or by sympatric speciation and accumulation of daughter species. Most empirical evidence point out the dominant action of allopatric speciation. We evaluate this general view by looking at a case study where sympatric speciation is suspected. We analyse the mode, tempo and geography of speciation in Diversity hotspots in islands are characterized by very high specific richness and endemism resulting from local diversification of groups which are \u201ctrapped\u201d in very limited spatial areas Empirical case studies showed or suggested that diversifications in islands most often result from repeated events of local allopatric speciation and subsequent establishment of microendemism New Caledonia, one of most diverse island biodiversity hotspots AgnotecousHere we analyse the mode, tempo and geography of speciation in the microendemic species of the cricket genus We use a dated species-level phylogeny, analyses of diversification time-course, and age-range correlation methods to investigate the mode of speciation and causes of microendemism. We aim at discriminating between two alternative scenarios:Under a scenario of dominant allopatric speciation, the observed pattern of sympatry is caused by secondary sympatry with post-speciational movements.Under a scenario of dominant sympatric speciation, the observed pattern of sympatry results directly from recent sympatric speciation, with little or no post-speciational movements.According to the dominant mode of speciation, we will compare and discuss the pattern of microendemism and tempo of species diversification in New Caledonia with respect to the influence of climatic changes combined with intricate soil distribution and mountain topography. This study will allow us understanding the origin of microendemic distributions in an evolutionary and biogeographical perspective.Agnotecous.

We tested the null hypothesis of equal diversification rates across the Agnotecous data set and using the estimated pure speciation value.We also compare the fit of rate-variable models to the null hypothesis of constant diversification by using likelihood methods based on birth-death models and model-fitting approach (BDL) implemented in the R package LASER A. petchekara is close to A. azurensis, A. humboldti and A. nekando are close to A. chopardi, and A. novaecaledoniae is close to A. sarramea (within clade B2).To compare diversification rates, we used APE Data on geographic distribution of the species were obtained from the collections of the following institutions: Mus\u00e9um national d\u2019Histoire naturelle (Paris), Natural History Museum (London), Queensland Museum (Brisbane), Osaka Museum of Natural History (Osaka), Naturhistorisches Museum (Vienna) and National Museum of Natural History (Leiden).

However the assessment of infarct zone (IZ) viability was not used as an inclusion criterion in the this trial. Several studies in patients with stable coronary artery disease have shown that only patients with preserved myocardial viability benefit from revascularization.Therefore we decided to assess the frequency of IZ viability in patients fulfilling the criteria for randomization in the OAT trial.Until now the registry included 16 patients screened for participation in the Cardiac magnetic resonance for the Occluded infarct-related Artery Treatment (COAT) trial which is a single center randomized study conducted in the Institute of Cardiology in Warsaw to compare late revascularization with optimal medical therapy alone on days 3-28 post MI in stable patients with preserved IZ viability. Estimated enrollment into the randomized phase is 40 patients. Viability is defined as necrosis transmurality <50% in at least 4 segments of IZ on cardiac magnetic resonance. The primary end-point of the study is a change in systolic wall thickening (SWT) at 6 months. Secondary end-points include change in left ventricular ejection fraction (LVEF), wall motion score index (WMSI), end-diastolic and end-systolic left ventricular volumes .In the studied group 8 patients (50%) did not have preserved viability of the infarct zone. Patients with preserved IZ viability were randomized to late revascularization (4 patients) or optimal therapy alone (4 patients).Lack of preserved IZ viability in 50% of patients fulfilling the criteria for randomization in the OAT trial might have influenced the negative results of this trial regarding late revascularization in STEMI. Hypothesis tested in the ongoing COAT trial assumes that late opening of the occluded infarct-related artery only in patients with preserved myocardial tissue viability may lead to improvement of left ventricular function and/or volumes."} +{"text": "Arabidopsis thaliana ovules initiate within the developing gynoecium from meristematic tissue located along the margins of the floral carpels. When fertilized the ovules will develop into seeds. SEUSS (SEU) and AINTEGUMENTA (ANT) encode transcriptional regulators that are critical for the proper formation of ovules from the carpel margin meristem (CMM). The synergistic loss of ovule initiation observed in the seu ant double mutant suggests that SEU and ANT share overlapping functions during CMM development. However the molecular mechanism underlying this synergistic interaction is unknown. Using the ATH1 transcriptomics platform we identified transcripts that were differentially expressed in seu ant double mutant relative to wild type and single mutant gynoecia. In particular we sought to identify transcripts whose expression was dependent on the coordinated activities of the SEU and ANT gene products. Our analysis identifies a diverse set of transcripts that display altered expression in the seu ant double mutant tissues. The analysis of overrepresented Gene Ontology classifications suggests a preponderance of transcriptional regulators including multiple members of the REPRODUCTIVE MERISTEMS (REM) and GROWTH-REGULATING FACTOR (GRF) families are mis-regulated in the seu ant gynoecia. Our in situ hybridization analyses indicate that many of these genes are preferentially expressed within the developing CMM. This study is the first step toward a detailed description of the transcriptional regulatory hierarchies that control the development of the CMM and ovule initiation. Understanding the regulatory hierarchy controlled by SEU and ANT will clarify the molecular mechanism of the functional redundancy of these two genes and illuminate the developmental and molecular events required for CMM development and ovule initiation.In flowering plants the gynoecium is the female reproductive structure. In Arabidopsis thaliana, two rows of ovules develop from a ridge of meristematic tissue on the inner surface of the seed pod or gynoecium. Within the developing ovule primordia, much is known about molecular patterning events along the proximal to distal axis and the mechanisms of integument development In both gymnosperms and angiosperms, ovules are critical for reproductive competence. Ovules contain the female gametophyte and thus the egg cell. Additionally, upon fertilization the ovules develop into the seeds that nurture and protect the developing embryos. In Gynoecial development in Arabidopsis initiates at stage 6 of floral development single mutant is nearly wild type while the aintegumenta (ant) mutant conditions the loss of about 50% of the ovule primordia. Together the loss of both the SEU and ANT activities in the seu ant double results in the complete loss of ovule initiation, indicating a synergistic genetic interaction and suggesting a degree of overlapping function for SEU and ANT during CMM development.A number of genes have been suggested to play a role in the maintenance of meristematic potential in the CMM and for the subsequent initiation of ovule primordia from the flanks of the CMM. While no single mutant has been reported to strongly disrupt ovule initiation, several higher order mutant combinations have been reported to disrupt the initiation of ovule primordia from the CMM SEU and ANT both encode transcriptional regulators ANT encodes an AP2-type DNA binding transcription factor that is expressed in all lateral organ primordia ANT is expressed throughout the stage 6 gynoecial mound with a higher level of expression within the adaxial core ANT is strong in the ovule anlagen and early ovule primordia as they arise. ANT activity during primordium development supports organ growth by maintaining the developmental period during which cell growth and cell divisions occur ANT has also been shown to contribute to proper specification of floral organ identity and polarity specification ANT regulation have not yet been published, PHB and cyclinD3 have been shown genetically to be downstream of ANT regulation ANT in organ polarity specification and regulation of cellular proliferation and/or organ growth.SEU encodes a transcriptional adaptor protein that is expressed widely throughout the plant SEU does not have a specific DNA binding activity but rather complexes with sequence specific DNA binding proteins in order to exert its effects on transcriptional regulation AGAMOUS (AG) expression during floral organ identity specification AG transcription through the recruitment of histone deacetylase proteins seu ant mutant is not conditioned simply by a de-repression of AG, but rather that SEU and ANT function to maintain or specify adaxial fate in the gynoecium and that this fate specification is critical for proper CMM development PHABULOSA (PHB) and REVOLUTA (REV) are reduced in the adaxial core of the stage 6 gynoecium in seu ant mutant plants. PHB and REV encode transcriptional regulators of the Homeodomain Leucine Zipper Class III type (HDZip-III) that are known to play a key role in the specification of adaxial identity in lateral organs SEU and ANT activity on HDZip-III expression was due to a direct or indirect regulation of their expression or accumulation. Additionally the defects in ovule and CMM development observed in the seu ant double mutant were not rescued when PHB activity was replaced, suggesting that either that PHB could not substitute for the other HDZip-III family members or that gene functions in addition to HDZip-IIIs are required downstream of SEU and ANT for CMM development ant rev double mutant, but not in ant phb double mutant support the idea of a functional differentiation between the PHB and REV activities within the CMM SEU and ANT that remain to be elucidated.A variety of experimental data suggest that the disruption of CMM development observed in the SEU and ANT are members of gene families whose members have been shown to share redundant function SEUSS-LIKE genes, SLK1, and SLK2 genetically enhance the ant mutant phenotype with respect to ovule initiation defects ANT-LIKE family member, AIL6, shares a critical redundant function with ANT as the ant ail6 double mutants flowers display reduced medial domain development and initiate very few ovule primordia ANT and the YABBY family members YAB1 and YAB3 is suggested by the synergistic disruption of ovule initiation observed in the ant yab1 and ant yab1yab3 mutants ant shatterproof1 (shp1) shatterproof2 (shp2) crabs claw (crc) mutants implicates the SHP MADS domain transcription factors in CMM development. These studies together highlight an important role for ANT function during CMM development and ovule initiation as well as reveal a high degree of functional redundancy within this tissue.Although no single mutant has been identified that eliminates CMM development or ovule initiation, a number of double mutant or higher order mutant combinations condition a severe disruption of the CMM and CMM-derived tissues (e.g. ovules) seu ant double mutant. In particular we sought to identify transcripts whose expression was dependent on the coordinated activities of SEU and ANT gene products. We hoped to both identify novel regulators of CMM development and to examine the molecular mechanism of the functional redundancy of SEU and ANT during CMM development. Our analysis identified a diverse set of transcripts that display altered expression in the seu ant double mutant tissues. Our in situ hybridization analyses indicate that many of these genes are preferentially expressed within the developing CMM. The analysis of overrepresented Gene Ontology classifications suggests a preponderance of transcriptional regulators including multiple members of the REPRODUCTIVE MERISTEMS (REM) and GROWTH-REGULATING FACTOR (GRF) families of transcriptional regulators are mis-regulated in the seu ant gynoecia. This study is the first step toward a detailed description of the transcriptional regulatory hierarchies that control the development of the CMM and ovule initiation.A number of key regulators of CMM development may be difficult to recover with standard forward genetic approaches due to a high degree of redundancy. Identifying genes that have specific patterns of spatial and temporal expression in the CMM would generate a set of candidate genes that could then be analyzed by reverse genetic approaches. In this paper we employ a transcriptomic profiling approach to identify sets of genes that are differentially expressed in the developing carpels of the seu ant double mutant relative to either single mutant. We isolated RNA from staged and hand-dissected gynoecia to limit the developmental window of the sample to the period just before and then during ovule primordia initiation, the earliest steps of ovule development. This differentiates our work from that of the Gasser and Colombo groups that have focused on later ovule developmental stages when identifying ovule-specific transcripts In an effort to identify novel regulators of CMM development and ovule initiation we identified genes that are preferentially expressed within the CMM within the context of the gynoecium. Additionally we endeavored to prioritize genes whose expression is synergistically disrupted in the seu-3, ant-1, and seu-3 ant-1 double mutant). We first analyzed mRNA accumulation in each single mutant relative to the Col-0 wild type gynoecial samples. To identify transcripts whose steady-state levels were altered in the single mutants relative to wild type, we utilized a 1-way ANOVA and identified probe sets (transcripts) that displayed a statistically significant difference in accumulation by the genotype term. This analysis identified 120 under-expressed and 200 over-expressed transcripts in the seu single mutant and 219 under-expressed and 241 over-expressed transcripts in the ant single mutant (We utilized the Arabidopsis ATH1 Gene Chip (Affymetrix) to compare transcript levels between four different genotypes over-represented GO terms suggest a role for this gene set in transcriptional regulation and relevant developmental processes, and 2) the reduced accumulation of these transcripts in the seu ant double mutant suggests that they may be preferentially expressed in the CMM in the wild-type gynoecium and, thus, are candidates for novel regulators of CMM development.We focused our attention on the genes that displayed seu ant double mutant we used a second analytical approach (Approach II) comprised of two steps. We first selected probe sets for which the mean expression was significantly lower in the seu or ant single mutant relative to wild type . These include AT1G02800 (ATCEL2), AT3G55560 (AGF2), AT5g57720 (REM15) AT2g46870 (NGA1), AT1G68640 (PAN), AT2G34710 (PHB), AT4G37750 (ANT), AT1G70560 (TAA1), AT5G18000 (VDD), AT3G17010 (REM22), and AT4G31610 (REM34 - previously AtREM1) PHB and TAA1) has been previously shown to be reduced in seu, ant or seu ant mutant gynoecia SEU and ANT have been implicated in the repression of AG in perianth organs, the levels of AG expression were not significantly different from wild type in the seu or ant single mutant gynoecial RNA samples . The Arabidopsis B3 superfamily consists of 118 genes all of which encode proteins containing one or more B3-type DNA binding domains. The B3 superfamily is comprised of four sub-families: REPRODUCTIVE MERISTEM); LAV (LEAFY COTYLEDON2[LEC2]-ABSCISIC ACID INSENSITIVE3 [ABI3]-VAL); ARF(AUXIN RESPONSE FACTOR);REM ( and RELATED TO ABI3RAV( and VP1). Six of the seven B3 regulators that were identified in our transcriptomics approach are from the REM subfamily for which there is little functional data. Four of these genes, AT4G31610 (REM34/AtREM1), AT5G18000 (VDD), At5G57720 (REM15) and AT3G17010 (REM22), have been previously reported to display CMM-enriched expression Surprisingly, seven out of the 31 Approach II candidate genes were members of the factors [49], with experiment number (E-MEXP-3293).Two analyses were run on our data. The first was a simple 1-way ANOVA by genotype. This method identified genes with expression levels that were statically different from that of the mean of the expression values. Class variables were specified as the genotype and the genotype was modeled as a fixed effect. The data was not compared to any baseline, but the LSMeans were run for simple differences of genotype using pFDR for the multiple testing method with an alpha of 0.05. Additionally we required that log2 of the magnitude of the expression level difference between the compared genotype means was greater than 0.35. The fixation method for the data points with large residuals was set as the False Positive Rate and the LSMeans standardization rate was set for Standard Deviation. The second analysis method (Approach II) was directed at detecting genes whose expression was synergistically affected in the enes See . Gene liseu, ant, and seu ant genotypes. Each biological replicate was assayed in triplicate. Results in ADENOSINE PHOSPHORIBOSYL TRANSFERASE1 . Results shown are the average expression normalized to APT1 and the standard error of the mean for four biological replicates.

Genetic analysis involving the study of loss of heterozygosity (LOH) has been evaluated on their tumours using well characterised and new markers of UC .Five of the six patients demonstrated informative results. Four of five (80%) of patients had synchronous or metacharonous UC tumour and showed patterns of LOH consistent with tumorigenesis from monoclonal tumour origin. One of five (20%) patients exhibited a LOH consistent with oligoclonal tumorigenesis.These findings suggest that both the monoclonal and field cancerization theory of tumorigenesis may play a role in tumors of the urothelial tract. However, more data is needed. Urothelial carcinoma (UC) of the bladder is the fifth most common solid cancer in the industrialized world as a measure of clonality model exposed to known carcinogen N-butyl-N-(4-hydroxybutyl)nitrosamine has shown oligoclonal tumour development in 30% of mice, suggesting that the field defect means of tumorigenesis plays a significant role in cancer of urothelial tract with UC of the UUT and synchronous or metachronous bladder UC that underwent surgical excision of their tumours were identified. These patients underwent nephroureterectomy for their UUT tumour(s) and transurethral resection of their bladder tumour(s). All tumours excised were high grade UC. The patients were not treated with any radiotherapy or chemotherapy prior to their surgical resection. Patients had not received any intravesical chemotherapy or immunotherapy for the bladder tumours. Tissue sample and microdissection: Formalin fixed paraffin embedded archival tissue was cut to 5um sections, and stained with haematoxylin and eosin for microscopic evaluation. Pathological identification of tumours was done with guidance of pathologist. Laser assisted microdissection of neoplastic tissue was performed using the PixCell II Laser-Capture Microdissection\u00ae apparatus was used to amplify genomic DNA at four specific loci on two different chromosomes: 9p21 (D9S171), 9q32 (D9S177), 9q22 (D9S303) and 17p13 (TP53). D9S171 is associated with tumour suppressor gene p16, a well characterized marker of early bladder tumorigenesis was examined in 6 patients. Of the six patients, five patients showed informative results (83%) in one of the four loci studied. However, no patient showed informative results through all four loci with informative loci showed a monoclonal pattern of LOH, while only one of five patients (. (20%) showed an oligoclonal pattern of LOH. Unfortunately, the patient with the oligoclonal pattern of LOH was male, and a confirmatory x-inactivation study could not be conducted. These findings are consistent with results seen by Sidranksy et al. Habuchi while the overgrowth of one clone in late stages tumorigenesis (high-grade tumours) may result in pseudomonoclonality or intraepithelial spread. In one of case however, there was evidence for tumour that may arise independently, consistent with the field cancerization model. This suggest that although the single cell theory of tumorigenesis may be the predominate means of UC progression, the field cancerization model may also play a small albeit significant role, which must not be overlooked when considering appropriate treatments modalities, and when using molecular diagnostic techniques to diagnosis and monitor for disease recurrence."} +{"text": "Right heart catheterization (RHC) is required for definitive diagnosis of pulmonary hypertension (PH) and serial echocardiograms or RHC are necessary for long term disease management.

Total MPs (anxV+), platelet MPs , tissue factor MPs , and endothelial MPs were assessed in venous blood samples. Measurement of MPs levels were obtained at early (<3 days) and delayed phase (7 to 10 days). Multiparameter MRI was performed to evaluate ischemic damage and vasospasm at the same time points. Qualitative evaluation of severity of ischemic damage was performed on DWI sequences. Levels of MPs were evaluated comparing different groups in terms of SAH severity , ECI severity and occurrence of delayed complications (vasospasm and DCI).n = 9) when compared with WFNS 1 to 2 (n = 16) patients. Interestingly, patients with most severe ECI and DCI showed the highest values of MPs, but this trend did not reach statistical significance, probably because of the small number of patients included in the study.Twenty-five patients were included in the analysis. Overall increased levels of MPs were observed at early phase after aSAH when compared with controls. Contrarily to our hypothesis, in the early phase no significant differences of MP level were observed in WFNS 4 to 5 (Microparticles and microthrombosis may increase the severity of early and delayed ischemic damage after aSAH."} +{"text": "Studies report that women with Rheumatoid Arthritis (RA) are not wearing therapeutic footwear.

Tau pathology is characterized by insoluble filamentous aggregates of hyperphosphorylated tau in CNS neurons known as neurofibrillary tangles (NFTs) and neuropil threads (NTs). NFTs and NTs are implicated in mechanisms of neurodegeneration through gains of toxic functions or losses of normal tau functions. Hyperphosphorylation and decreased solubility of tau leads to a loss of the ability of tau to bind to and stabilize microtubules (MTs) which impairs axonal transport and results in neuronal dysfunction and degeneration. This presentation describes the use of MT stabilizing drugs to counteract the loss of tau function and prevent/ameliorate tau mediated neurodegeneration in a transgenic (Tg) mouse model of an AD-like neurodegenerative tauopathy. Briefly, proof of concept prevention and intervention studies of the brain-penetrant MT-stabilizing agent epothilone D (EpoD) are described in young (prevention) and aged (intervention) P301S mutant tau Tg mice (PS 19 mice) with little (young PS 19 mice) or abundant tau pathology and behavioral impairments (aged PS19 mice). In the prevention and intervention studies, EpoD treatment reduced axonal dystrophy and increased axonal MT density which led to improved neuronal integrity and cognitive performance. EpoD treatment also improved fast axonal transport in the aged PS19 Tg mice. Unexpectedly, aged PS19 mice treated with EpoD showed a marked reduction in forebrain tau pathology and increased hippocampal neuronal integrity. There were no dose-limiting side effects in the EpoD treated young and aged PS19 mice. These studies support the view that EpoD and other brain-penetrant MT-stabilizing drugs offset the loss of tau function in neurodegenerative tauopathies and therefore are potential therapeutics for the treatment of AD and related tauopathies. Finally, a new seeded transmission model of tauopathy is presented using injections of preformed tau fibrils into the brains of PS19 mice which presents new opportunities to assess the efficacy of MT stabilizers and other potential passive immunization therapies for AD and related tauopathies.Supported by grants from the NINDS/NIA."} +{"text": "The overall outcome of HIV disease may depend on the host's capacity to maintain dendritic cell (DC) homeostasis at mucosal sites, where DC populations, one of the earliest cell types to be exposed to the virus, present an inherent capacity to modulate the balance between tolerance and protection.

The importance of the medium spiny projection neurons is highlighted by the severe debilitation associated with the loss of their dopaminergic input in Parkinson\u2019s disease or degeneration of these cells in Huntington\u2019s disease . Approximately half of all medium spiny striatal neurons express the dopamine D1A receptor (Drd1a) and these neurons comprise the direct output pathway to the medial globus pallidus and substantia nigra pars reticulata . Early deletion of the Drd1-expressing striatal neurons in mice results in severe motor impairment, eating deficits and reduced striatal volume . In order to separate potential developmental effects from the normal role of the Drd1a-expressing striatal cells in adult mice, we have made a mouse model that allows for the inducible deletion or expression of targeted genes specifically within the Drd1a-expressing striatal neurons using BAC transgenesis.A bacterial artificial chromosome (BAC) designated RP23-47M2 was obtained from BACPAC resources of the Children\u2019s Hospital Oakland Research Institute (CHORI). This BAC contains the Drd1a locus. Using the techniques of bacterial homologous recombination , a cassette containing the reverse tetracycline-controlled transactivator (rtTA) fused to the herpes simplex virus VP16 transactivator was inserted at the ATG start site of the Drd1a locus. Transgenic mice with the modified BAC randomly integrated into their genomes were produced by microinjection of the modified BAC into mouse zygotes at the University of Michigan Transgenic Core. Transgenic mouse lines carrying the rtTA allele were crossed with reporter transgenic mice carrying the allele for tetO-lacZ. In bi-transgenic mice this approach (TET-ON) allows for the activation of the tet operator by rtTA in the presence of doxycycline (DOX). Therefore, during DOX administration, the lacZ gene produces \u03b2-galactosidase which can be detected through X-gal staining.Drd1a-rtTA/tetO-lacZ lines were screened and at least one line to date has shown strong expression specifically within the mouse striatum. X-gal staining is present throughout the striatum, with somewhat higher levels in the medial aspects of the structure. We are continuing to screen additional lines and are determining the minimal parameters of DOX administration (dose and duration) necessary for the inducible expression of rtTA/VP16.We have made the first inducible Drd1a TET-ON mouse. This mouse, in conjunction with other transgenic models, will allow for the inducible expression or deletion of target genes specifically within Drd1a-expressing cells and will be highly useful in the study of Parkinson\u2019s and Huntington\u2019s diseases, addiction and the normal role of Drd1a-expressing cells."} +{"text": "Adverse drug reactions (ADR) appear more frequently then what is actually reported and registered.

ADR were recorded in the following way: patients were interviewed on the basis of a symptoms list and any signs which could point to eventual ADR. Secondly, lab tests and other available parameters were monitored.At the time when interviews took place, patients received on average 8.0 \u00b1 2.6 medicines (2\u201317). In total, 67 patients (33%) had 75 ADR. Twenty one ADR (28%) are classified as serious. Fifty four ADR resulted in the recovery of the patient (72%), eight had as an outcome prolonged hospitalization (11%), another eight were life threatening (11%), while five ADR (6%) were the cause of the hospitalization. The most frequent ADR which had as an outcome admission to hospital were caused by digoxin (40%), prolonged hospital stay by furosemide (38%), while the most frequent registered ADR which were life threatening were caused by streptokinase (50%).Monitoring ADR in patients using cardiovascular drugs is a matter of importance since this class of medicines is usually used by elderly patients with critical conditions and accompanying diseases. Considering increased use of cardiovascular drugs and limitations in pre-marketing trials for drug safety evaluation, post marketing evaluation of adverse drug reactions induced by this class of medicinal products seems necessary.

To verify the frequency, the anatomical localization and the phenotype of misplaced endometrial tissue along the fetal female reproductive tract, histological and immunohistochemical analyses of uteri, fallopian tubes, and uterosacral ligaments were performed. Methods: Reproductive organs were collected from seven female fetuses at autopsy, five of them from gestational ages between 18 and 26\u2009weeks and two fetuses with gestational ages of 33 and 36\u2009weeks deceased of placental anomalies. Serial sections from areas containing ectopic glands and embryonic duct residues were analyzed by histological and immunohistochemical procedures. Results: Numerous ectopic endometrial glands and stroma were detected in the myometrium in two fetuses with low levels of expression of estrogen receptor-alpha (ER-\u03b1) and progesterone receptors (PR). The embryonic ducts were localized in the uterine broad and ovarian ligaments and under the fallopian tube serosa in six fetuses. Low levels of steroid receptors expression were found in the embryonic residues, whereas the carcino-embryonic antigen (CEA) and the tumor marker Ca 125 were not detected. The embryonic residues stromal component strongly expressed the CD 10 and vimentin proteins. Conclusion: The anatomical and the immunohistochemical features of the ectopic organoid structures identified in fetal female reproductive tract suggest that endometriotic as well as neoplastic disease in adult women may develop on the basis of misplaced endometrial glands and/or embryonic cell remnants. Endometriosis is a heterogeneous gynecological disease clinically characterized by the presence of different anatomo-clinical subtypes Giudice, . The mosIn the present study, we evaluated the incidence and the anatomical location of displaced endometrial tissue in the reproductive tract in seven female fetuses. Serial sectioning of the reproductive organs was realized followed by immunohistochemical analysis of tissue areas containing ectopic glands and embryonic cell rests. It was observed that the anatomical and the phenotypic features of the mislocated tissue components recall some pathological characteristics of both benign and malignant gynecological conditions.Reproductive organs from a series of seven human female fetuses at different gestational ages ranging from 18 to 36\u2009weeks were obtained at autopsy. All together, the causes of fetal death were placental pathology in two samples, cardiac malformations in two cases and voluntary abortions in three. The reproductive organs were carefully dissected, fixed in buffered formaldehyde, and included in paraffin.Between 200 and 400 serial sections with thickness of 5\u20137\u2009mm from each paraffin block containing uteri, fallopian tubes, ovaries, and uterosacral ligaments were prepared and stained by hematoxylin and eosin (H&E). To ascertain tissue sections containing ectopic endometrial glands and/or embryonic duct remnants, every sixth slide was separately stained and microscopically analyzed.The following antibodies were employed; rabbit anti estrogen receptor-alpha (ER-\u03b1), ; monoclonal mouse anti human progesterone receptor, clone PR 636 ; monoclonal anti human CA125, clone M11 CA125 (Dako); monoclonal anti human CD10 clone 56C6 (Dako); monoclonal anti human carcino-embryonic antigen (CEA) clone II-7 (Dako); rabbit anti human alpha-1-foetoprotein (Dako); monoclonal anti human epithelial membrane antigen (EMA) clone E29 (Dako); mouse anti human Cytokeratin 7 and monoclonal mouse anti-vimentin clone VIM 3B (Dako).Five micrometres thick sections were deparaffinized in xylene, rehydrated through graded alcohol series, and washed in PBS. For antigen retrieval, the slides were immerged in citrate buffer (pH\u2009=\u20096.0) during 25\u2009min at 96\u00b0C essentially as described , PR (14%), and ER-\u03b1 (6%) was revealed in the ectopic glandular structures localized in the uterine wall. A strong expression of CD10 (41.3%) but lower level of vimentin specific immunolabeling (20%) was observed in the stromal component surrounding the displaced glands. Representative illustrations of PR expression in orthotopic endometrial cells as well as the expression of PR, ER-\u03b1, and CD10 in the uterine ectopic glands and stroma are shown in Figures Concerning the embryonic remnants, consistent EMA immunostaining ranging between 32 and 53% was detected in the duct lining cells, while lower level of expression in duct cells of both ER-\u03b1 10\u201323%) and PR (13\u201344%) molecules was found in all samples. The stromal-like component surrounding the duct residues contained between 1 and 3% of immunoreactive cells for ER-\u03b1 and between 4 and 13% of immunoreactive cells for PR. Approximately 2\u201311% of the ductal cells and 1\u20133% of the stormal cells expressed cytokeratin 7, while CEA and CA125 molecules were not detected. Using anti alpha-1-fetoprotein antibody, close to 42% of the epithelial and duct surrounding mesenchymal cells were intensely immunoreactive on sections from two fetuses. Representative illustrations of the embryonic duct residues labeled with anti ER-\u03b1, anti PR, anti alpha-1-fetoprotein and anti CD10 antibodies are shown in Figures 0\u201323% andIn this study we show presence of misplaced endometrial glands and embryonic duct-like remnants in the reproductive organs in six of seven examined female fetuses. The phenotypic features of the ectopic glands in the myometrium of two fetuses indicate particularly weak expression of PR and ER-\u03b1 steroid hormone receptors in comparison to their high level of expression in cells lining the endometrial cavity. In these two cases, moderate level of PR expression was also revealed in the cell nuclei of the stromal component, while ER-\u03b1 receptors were not found. Overall, the presented findings are in accordance with other studies describing the levels of ER-\u03b1 and PR in misplaced glands in patients with both endometriosis and adenomyosis (Van der Walt et al., Concerning the foci of embryonic duct remnants observed, moderate expression of PR and low levels of ER-\u03b1 were uniformly revealed in the epithelial cells in all cases. Histologically, some ducts appeared dysplastic and surrounded by a dense cellular stromal layer consistently expressing vimentin and CD10 molecules. Of interest, these tubular structures in most of the samples did not clearly express cytokeratin 7, and Ca 125 protein molecules. This might be related to particular phenotypic features of coelomic metaplastic cell rests at given gestational age (Batt and Smith, de novo expression of this protein in ovarian malignancy arising from endometriosis (Horiuchi et al., In spite of the limited number of studied cases, the findings of ectopic glands and/or embryonic ducts in the reproductive tract of female fetuses is a remarkable phenomenon that could be referred to the theory of involvement of M\u00fcllerian or Wolfian cell rests in the pathogenesis of both endometriosis and particular pelvic malignancies Fujii, . At presIn conclusion, the presented data support the theory that at least some subtypes of endometriotic and gynecological neoplastic lesions may be related to anomalies occurring during the embryogenesis. These data stand in relationship with the embryological origin of certain pelvic malignancies based on the metaplastic potentiality of the secondary M\u00fcllerian system. The observed frequency of displaced embryonic structures, also suggests a complex pathogenetic mechanism in the development of endometriosis-associated neoplasms including genetic, hormonal, and/or environmental events. Consequently, further studies of endometriotic and neoplastic lesions should include novel embryonic cellular phenotypic markers, that could provide important diagnostic and predictive information to guide clinical decision making.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "Our objective was to investigate the molecular mechanism underlying the processing of proBNP, levels of which are increased in heart failure ,2.Rat neonatal atrial and ventricular myocytes were cultured separately.

Each trial report was reviewed to determine the extent and nature of reporting on DTP and whether statistical methods were used to deal with DTP for both benefit and harms analyses.Even the most basic adherence information was not presented in some trials. Forty-two publications did not state how many patients actually initiated their randomised treatment. Information about treatment discontinuation can be vague and may not allow assessment of the number of patients who completed the treatment protocol.Ninety-eight publications reported at least one form of DTP, including non-receipt of allocated treatment , incomplete treatment in those who initiated allocated treatment (78), switching trial treatments (12), starting disallowed/non-trial treatment (4), starting open label treatment out of trial (7), contamination across groups (3) and other nonadherence to treatment dose or schedule (23). Treatment providers were reported to be nonadherent when delivering treatment in 12 trials.More than half (50 (51%)) of the publications that reported DTP used some method to deal with it, but none were based on randomisation-preserving techniques. The most common method was based on per protocol (PP) analysis (46) (including one instance of using inverse probability of censoring weighting) often labelled as intention to treat (ITT) (18) or modified ITT (5), but missing data techniques (2) and as treated analyses (3) were also implemented. Less than 40% (26) of the 69 trials which presented harms analyses specifically defined harms analysis populations, and the majority of these definitions were based on actual treatment received (18). The majority (31) of the 43 trials that did not explicitly specify harms analysis population appeared to analysed harms outcomes using ITT. Twelve reports explicitly commented on the fact that DTP was likely to have influenced the observed treatment effect.DTP data presented in RCT publications, particularly related to treatment initiation and discontinuation, may be ambiguous or scant.

In recent times PAC has been used less with less invasive methods becoming more popular.

EndoMT is a complex biological process induced by members of the transforming growth factor (TGF-\u03b2) family of regulatory polypeptides in which endothelial cells adopt a mesenchymal or myofibroblastic phenotype acquiring motile and contractile properties and initiating expression of mesenchymal cell products such as \u03b1 smooth muscle actin (\u03b1-SMA) and type I collagen. Although these experimental studies provide compelling evidence for the participation of EndoMT in the development of experimentally-induced fibrotic processes the precise role of EndoMT in the pathogenesis of human fibrotic disorders requires confirmation and validation from studies of human clinical pathologic conditions. Such confirmation should lead to a change in the paradigm of the origin of profibrogenic myofibroblasts involved in human fibrotic diseases. Further understanding of the molecular mechanisms and the regulatory pathways involved in EndoMT may lead to the development of novel therapeutic approaches for the incurable and often devastating fibrotic disorders. It is generally accepted that activated mesenchymal cells or myofibroblasts play a crucial role in the pathogenesis of various fibrotic diseases including interstitial pulmonary fibrosis, systemic sclerosis and liver or cardiac fibrosis being responsible for the exaggerated production and accumulation of extracellular matrix proteins in various organs affected by these diseases -4. AlthoThe occurrence of EndoMT in experimentally induced cardiac fibrosis was originally described by Zeisberg et al. employinin vitro. The treated cells displayed a progressive loss and the eventual disappearance of endothelial-specific cell markers (CD-31 and VE-cadherin) and a parallel acquisition of mesenchymal cell markers including vimentin, collagen I and N-cadherin. These results suggested that intestinal endothelial cells exposed to an inflammatory environment may participate in the intestinal fibrotic process which accompanies intestinal inflammatory diseases. The in vitro observations were confirmed by studies of molecular co-localization in human colonic mucosa [In contrast with the extensive evidence from experimental animal models demonstrating the important participation of EndoMT in the development of tissue fibrosis studies with human endothelial cells are just beginning to appear.

However, larger datasets and results of ongoing adjuvant trials are needed to provide confirmatory evidence for or against the concept and feasibility of withdrawal therapy in locally advanced and metastatic breast cancer.The authors declare that they have no competing interests.KLC conceived this study.

The resultant wounds are generally deep and associated with prolonged healing times. Negative pressure wound therapy (NPWT) is increasingly used to facilitate healing of these complex wounds. This retrospective audit provides outcome data on patients with post-surgical wounds managed with NPWT within our High Risk Foot Service (HRFS). There is a paucity of data on clinical outcomes of DRFU treated with this therapy.Data from patients treated for post-surgical wounds within the HRFS was extracted from our electronic data base. A manual review of the patients records treated with NPWT was conducted to determine wound severity (University of Texas grading system), time to healing (from date of surgery), duration of NPWT and complications including new or recurrence of wounds and the need for further surgical management.155 patients with post surgical wounds were managed by the HRFS between September 2006 and November 2010. Many (83%) of these were superficial ulcers (grade 1), the remainder involved tendon and or bone (Grade 2 and 3). Thirty seven patients (37 wounds) were treated with NPWT. Two were superficial (grade 1), 19 were to tendon (grade 2) and 16 were to bone (grade 3). Most (34) were clinically infected at baseline and 13 were ischaemic. Median time to healing (from the date of surgery) was 121 days. Twenty one healed and 5 cases are ongoing. NPWT was used for a median of 30 days. Two required further foot surgery before healing, 14 patients developed new ulcers (unrelated to NPWT), 3 patients who healed required below knee amputation within 2 years and 1 died during the follow-up period.NPWT is often used in our service for the management of complex post surgical wounds with close to 60% achieving complete wound closure and a low rate of major amputation. While many factors may influence this result, the increasing use of NWPT is supported in this setting. Data collection is ongoing and we plan to compare these outcomes to a historical control group and hope that this sets a benchmark for appropriate use of NPWT."} +{"text": "Cancer remains a major health concern in the management of HIV infection in areas of the world with and without access to highly active antiretroviral therapy.

The increasing implementation of clinical information systems in the UK and internationally provide new opportunities to systematically identify patients at risk of PDRM for targeted medication review. The objectives of this study were (1) to develop a set of explicit medication assessment criteria to identify patients with sub-optimally effective or high-risk medication use from electronic medical records and (2) to identify medication use topics that are perceived by UK primary care clinicians to be priorities for quality and safety improvement initiatives.For objective (1), a 2-round consensus process based on the RAND/UCLA Appropriateness Method (RAM) was conducted, in which candidate criteria were identified from the literature and scored by a panel of 10 experts for 'appropriateness' and 'necessity'. A set of final criteria was generated from candidates accepted at each level. For objective (2), thematically related final criteria were clustered into 'topics', from which a panel of 26 UK primary care clinicians identified priorities for quality improvement in a 2-round Delphi exercise.(1) The RAM process yielded a final set of 176 medication assessment criteria organised under the domains 'quality' and 'safety', each classified as targeting 'appropriate/necessary to do' or 'inappropriate/necessary to avoid' (safety) medication use. Fifty-two final 'quality' assessment criteria target patients with unmet indications, sub-optimal selection or intensity of beneficial drug treatments. A total of 124 'safety' assessment criteria target patients with unmet needs for risk-mitigating agents, high-risk drug selection, excessive dose or duration, inconsistent monitoring or dosing instructions. (2) The UK Delphi panel identified 11 (23%) of 47 scored topics as 'high priority' for quality improvement initiatives in primary care.The developed criteria set complements existing medication assessment instruments in that it is not limited to the elderly, can be implemented in electronic data sets and focuses on drug groups and conditions implicated in common and/or severe PDRM in primary care. Identified priorities for quality and safety improvement can guide the selection of targets for initiatives to address the PDRM problem in primary care. Systematic reviews have demonstrated deficits in the quality and safety of medication use in primary care to an extent sufficient to constitute a public health threat. Three to four percent of all unplanned hospital admissions are due to preventable drug related morbidity (PDRM), with the majority attributed to high-risk prescribing and inconsistent monitoring -4. AntipThe 'Data-driven Quality Improvement in Primary care (DQIP)' research programme is designing and testing a complex intervention to improve the quality and safety of medication use in UK primary care. It is based on encouraging and facilitating primary care medical practices to systematically and continuously identify, correct or otherwise manage drug therapy risks that are potential pre-cursors to PDRM . The DQIA number of explicit medication assessment tools have been developed in recent years. The Beers criteria set lists potopics, are perceived to be priorities for quality improvement by professionals working in UK primary care.The study had two aims. First, we aimed to develop and classify by clinical importance a set of up-to-date medication assessment criteria that can be implemented in routine primary care clinical datasets to identify instances of (a) sub-optimally effective medication use for conditions commonly encountered in primary care and (b) high-risk use of drugs that have been shown to either commonly cause harm and/or cause severe harm in primary care. Second, we aimed to elicit the extent to which thematically-related medication assessment criteria, subsequently referred to as The study was conducted in three stages. First, an extensive list of candidate medication assessment criteria was generated based on a structured literature review. Second, an expert panel participating in a modified RAND/UCLA (University College of Los Angeles) Appropriateness Method (RAM) study scored these items by clinical importance based on a summary of research evidence and their clinical judgement. Candidate criteria with high importance scores were translated into a final criteria set by removing redundancies (see below). Final criteria were characterised by the type of medication use targeted, informed by available taxonomies -15. ThirPrescribing is a ubiquitous feature of medical care which makes a systematic evaluation of the literature on prescribing quality or safety unfeasible in a single research project. We therefore focussed on medication use for conditions commonly encountered in primary care and drugs with clear evidence of significant benefit or harm. The literature review drew initially on UK national clinical guidelines, prescribing advice, and safety alerts, supplemented by European or other clinical guidelines and targeted primary literature review in selected areas as detailed below.Candidate medication assessment criteria either described potentially beneficial medication use or the use of potentially harmful treatments ('safety'). Candidate 'quality' criteria targeted common conditions where there are compelling indications for drug therapy based on UK and European guidelines -25. CommIn order to identify candidate safety criteria, the drug groups reported to be most frequently implicated in PDRM hospital admissions were identified from systematic reviews and large scale studies -4,34. FoThe RAND/University of California Los Angeles (UCLA) appropriateness method is a rigorous way of combining research evidence with expert opinion , and hasimproper' not to be offered or avoided, whereas 'appropriate' is a more neutral balancing of net benefit or harm [The questionnaire aimed to classify candidate medication assessment criteria derived from the literature as either 'necessary' or 'appropriate' care table . 'Necess or harm -45. Foll or harm ,46.and three or more ratings of 1 to 3) on the appropriateness scale were rejected. Those items with median ratings of 7 to 9 were accepted as 'appropriate' and those with median ratings of 1 to 3 as 'inappropriate'.All candidate quality and safety assessment criteria were scored for 'appropriateness'. Candidate criteria with a median rating of 4 to 6 ('uncertain') or disagreement were accepted. Candidate safety assessment criteria were additionally scored on a 'necessary to avoid' scale, where items with a median rating of 1 to 3 (= clearly necessary to avoid) were accepted. Candidate criteria with median ratings of < 7 on the 'necessary to do' and > 3 on the necessary to avoid scale and those showing disagreement (defined as above) were rejected. The concept of 'necessary to avoid' was an extension to the original RAM method to differentiate between prescribing that is 'generally not worthwhile' from 'improper' in safety terms (see box 2).The ten RAM panel members were emailed the first round questionnaire and a summary of the supporting evidence base. Panellists were asked to rate each item with reference to an 'average' patient consulting an 'average' primary care clinician in 2009 based on both the evidence summary and their clinical judgement . PanelliA random sample of general medical practitioners (GPs) and eligible pharmacists in Scotland and England was invited to participate by e-mail. In order to be eligible, pharmacists had to have experience of working in medicines governance, as a prescribing advisor or as a practice pharmacist. Twenty three (64%) GPs and 13 (36%) pharmacists agreed to participate.'The described topic is a priority for collaborative quality improvement in primary care'. The term 'collaborative' was used in order to emphasise that the intended purpose of this study was to identify priority topics for quality improvement rather than measures for judging practitioners or practices as part of performance management.The Delphi questionnaire listed the medication improvement topics to be scored together with a short summary of the scientific rationale for each topic. For each item, panellists were asked to state their level of agreement with the statement and 30% or more ratings of 7 to 9) were accepted as 'priority', with median ratings of 8 or 9 defined as 'high priority'. All findings reported in this paper refer to second round ratings.As in the RAM study, all ratings used an ordinal scale of 1 to 9 (1 = strongly disagree and 9 = strongly agree). Panellists were instructed to rate topics in relation to primary care in general, rather than their own practice. The first round ratings were summarised and returned to participants by email for a second round of scoring. Topics with second round median ratings of 7 to 9 without disagreement candidate assessment criteria. Upon completion of the second rating round, 318 (82%) candidates were accepted at the 'appropriate' and 275 (71%) items at the 'necessary' level. A number of candidate criteria were duplicates, in the sense that they were designed to determine thresholds beyond which care was judged appropriate and necessary. For example, 18 candidate quality assessment criteria related to glycated haemoglobin (HbA1c) levels beyond which treatment intensification was appropriate or necessary. Removing redundant candidate criteria yielded 52 quality and 124 safety assessment criteria to be included in the final set. Forty (77%) final quality assessment criteria and 107 (86%) final safety assessment criteria were derived from candidates accepted at the 'necessary' level. The results of the RAM study are summarised in tables Table Similarly, table The majority of safety assessment criteria are drug-focussed (74%), either targeting drugs reported to be frequently implicated in PDRM hospital admissions (54% - section A) or others implicated in severe preventable harm (20% - section B). The remainder (26% - section C) target medication use in particularly vulnerable groups, namely the elderly 15%), patients with heart failure (8%) and children (4%). Over a third (36%) of final safety assessment criteria focus on potentially harmful use of NSAIDs, antiplatelets, anticoagulants and diuretics, the drug groups most frequently implicated in PDRM hospital admissions [5%, patieOver half (52%) of safety criteria target the selection of high-risk drugs (MS2 to 4), either for indications where safer alternatives exist (MS2) or in patients particularly susceptible to adverse reactions because of age/co-morbidity (MS3) or co-prescription (MS4). A further 15 (12%) criteria target omissions of drugs indicated to mitigate the risk of adverse events from high-risk treatments (MS1), while twenty (16%) criteria target inconsistent laboratory monitoring (MS8). Two (2%) criteria focus on prescribing that may jeopardise patient compliance with methotrexate dosing schedules (MS7).The majority of quality (81%) and safety (71%) assessment criteria are not restricted to the elderly (patients aged 65 years or older).Grouping of thematically related assessment criteria that were derived from candidates accepted at the 'necessary' level yielded a total of 47 medication improvement topics to be rated by the Delphi panel. Thirty-six Delphi study participants completed a first round and 26 (73%) a second round questionnaire and high-risk use, inconsistent monitoring or patient instructions for drugs implicated in preventable harm (medication use safety) in primary care. All items are classified by clinical importance (appropriateness and necessity) as the output of an extended RAM process. Key professionals in UK primary care identified eleven clusters of thematically related medication assessment criteria (topics) as 'high priority' for quality improvement initiatives. The three highest rated topics related to methotrexate dosing instructions, high-risk prescribing of NSAIDs and antiplatelets and underuse of corticosteroids in asthma.The RAM approach had advantages over the Delphi technique as an initial step in the criteria development process, because the face-to-face meeting ensured the necessary commitment of panellists to place ratings on an extensive and thematically broad list of candidate criteria that were grounded in the evidence base. The original RAM approach was extended in this study by introducing the concept of 'necessary to avoid', in order to distinguish between inappropriate ('not worthwhile') and 'improper' medication use in safety terms results in the UK are often held in bespoke systems which hinder the implementation of meaningful measures for monitoring anticoagulant use -4. SimilAlthough the DQIP criteria set has been developed for application in UK primary care, the drug groups reported to be implicated in PDRM events in primary care are similar internationally -52, and The Delphi approach allowed stakeholders in primary care to prioritise the chosen medication use topics for improvement initiatives in UK primary care. The Delphi panel was deliberately chosen to include both day to day prescribers and those involved in prescribing governance and improvement (predominately pharmacists but including GPs with a more strategic role). A limitation is that our focus on professionals involved in primary care prescribing meant that we did not seek to include either specialist or patient/public perspectives in the Delphi panel. Since there is evidence that practitioners' perceptions of a targeted behaviour as meaningful is a pre-requisite to changing behaviour we aimedIt is important to note that even those topics that were not considered to be priorities contain individual criteria that were agreed to be 'necessary' to do or avoid by the RAM panel. Examples are 'inadequate dose titration of ACEI, ARBs and beta blockers in chronic heart failure', and the 'using of warfarin without a compelling indication in atrial fibrillation with low risk of stroke'. These should therefore not be neglected. Lower priority ratings nevertheless indicate that changing and improving the corresponding medication use aspects may require targeted effort (or resources) in order to influence prescribing behaviour.NCT01425502).The DQIP medication assessment criteria set presented here has been developed using established consensus methods and complements existing medication assessment instruments by not being limited to the elderly and by targeting a wide spectrum of medication use practices implicated in common and/or severe PDRM events in primary care. As all previously published explicit medication assessment tools, the criteria set presented here does not, however, provide comprehensive coverage of all situations that put patients at risk of PDRM, reflecting the large scope and high complexity of medication use in primary care and the limitations of current UK clinical information systems. The best choice of criteria set will therefore depend on the main purpose to be addressed and will be guided by local priorities. Informed by the priority ratings of a panel of UK primary care professionals, we have selected a subset of the DQIP criteria to serve as outcome measures in a cluster randomised trial evaluating the effectiveness of a complex intervention to improve prescribing safety and the extent to which any improvements in prescribing or monitoring translate into improved patient outcomes therefore deserve further study.ACEI: Angiotensin converting enzyme inhibitor; ACOVE: Assessing care of vulnerable elders; ACS: Acute coronary syndrome; ADE: Adverse drug event; AF: Atrial fibrillation; ARB: Angiotensin receptor blocker; BB: Beta blocker; BP: Blood pressure; CCB: Calcium channel blocker; 2: CHADSScore for stroke risk assessment in atrial fibrillation based on the following risk factors: cardiac failure, hypertension, age > 75, diabetes and stroke; CHD: Coronary heart disease; CHD: Coronary Heart Disease; CHF: Chronic heart failure; CKD: Chronic kidney disease; CKD: Chronic kidney disease; COPD: Chronic obstructive pulmonary disease; COX: Cyclo-oxygenase; CVD: Cardiovascular disease; DM: Diabetes mellitus; DMARD: Disease modifying antirheumatic drug; DQIP: Data driven quality improvement in primary care; eGFR: Estimated glomerular filtration rate; FBC: Full blood count; GIP: Gastro-intestinal protective agents; GP: General practitioner; HbA1c: Glycated haemoglobin; HIV: Human immunodeficiency virus; HRT: Hormone replacement therapy; HTN: Hypertension; INR: International normalised ratio; IT: Information technology; MI: Myocardial infarction; MTX: Methotrexate; NSAID: Non-steroidal anti-inflammatory drug (includes non-selective and COXII selective agents unless stated otherwise); NS NSAID: Non-selective NSAID NYHA: New York Heart Association; PDRM: Preventable drug related morbidity; RAM: RAND appropriateness method; SABA: Short acting beta 2 receptor agonist; SD: Standard deviation; START: Screening tool to alert doctors to right treatment; STOPP: Screening tool of older person's prescriptions; TCA: Tricyclic antidepressant; TIA: Transient ischaemic attack; U&E: Urea and electrolytes; UCLA: University College of Los Angeles; UK: United Kingdom; Z-drug: zopiclone, zolpidem or zaleplone.The authors declare that they have no competing interests.The study is part of the Data-driven Quality Improvement in Primary Care (DQIP) research programme, which is led by BG.

A successful continuation of rheumatology follow-up beyond childhood depends on how clinicians think about transfer and transition (2).To explore the attitudes of rheumatology practitioners on transfer and transition from pediatric to adult health care of adolescents with a rheumatic disorder.A survey among rheumatology practitioners attending the Pediatric Rheumatology European Society congress in 2010. Overall, 138 individuals participated, of which 59 were medical doctors (MDs) with paediatric and rheumatology background; 30 MDs with pediatric background; and 21 MDs with rheumatology background.Participants judged that, when patients with active rheumatic disorder reach adulthood, they should receive medical follow-up from an adult rheumatologist (87%). Only 19% thought that patients should stay under surveillance of a paediatric rheumatologist. Several initiating factors for transfer were marked as important: readiness of the patient according to the caregiver (62%), age (61%) and psychosocial maturity (49%). A transfer meeting with the patient (76%), a referral letter (73%), or a medical transfer file (64%) were most preferred transfer communication tools with adult healthcare. Joint outpatient clinic, phone calls, and transfer meetings without the patient were considered to be less useful. The pediatric (94%) or adult rheumatologist (83%), parents (81%) and the nurse specialist (74%) were stated as most important active participants in the transition process.This study emphasized the importance of transfer to specialized rheumatology care of adolescents with an active rheumatic disease and highlighted transfer initiators and transfer communication tools."} +{"text": "We analysed the responses using descriptive statistics; 660 individuals responded to the public and 303 individuals responded to the expert survey. We found evidence of public skepticism about the use of neuroimaging for applications such as lie detection or to determine consumer preferences and considerable disquiet about use by employers or government and about how their data would be stored and used. While also somewhat skeptical about new applications of neuroimaging, experts grossly underestimated how often neuroimaging had been used as evidence in court. Although both the public and the experts rated highly the importance of a better informed public in limiting the inappropriate uses to which neuroimaging might be put, opinions differed on the need for, and mechanism of, actual regulation. Neuroscientists recognized the risks of inaccurate reporting of neuroimaging capabilities in the media but showed little motivation to engage with the public. The present study also emphasizes the need for better frameworks for scientific engagement with media and public education.Emerging applications of neuroimaging outside medicine and science have received intense public exposure through the media. Media misrepresentations can create a gulf between public and scientific understanding of the capabilities of neuroimaging and raise false expectations. To determine the extent of this effect and determine public opinions on acceptable uses and the need for regulation, we designed an electronic survey to obtain anonymous opinions from as wide a range of members of the public and neuroimaging experts as possible. The surveys ran from 1 Am I politically right or left wing? Which of sex or money interests me most? Should I take an fMRI lie detector test? Can other people see my dreams? Can neuroimaging help me chose the right career? Can imaging identify future criminals amongst young children? The potential for new technologies to improve the health, living and economic prospects of society quite rightly attract public curiosity We are exposed, almost weekly, to reports of new, thrilling and increasingly fantastical applications of neuroimaging to unravel the complexities of our minds \u2013 Misinterpretations of neuroimaging research by the public may arise in several ways: the distortion of findings by scientists or the media to enflame interest, through commercial interests, or poor engagement of the public by researchers. Promotion of the level of public understanding of neuroscience concepts Motivated by the need for evidence-based solutions to these challenges, we surveyed the public for their thoughts on the current uses, communication of, and need for regulation of, neuroimaging research. In parallel, we also surveyed experts in neuroimaging to provide a benchmark of the scientifically accepted uses and identify where public and professional opinions might differ.We designed two short questionnaires, one for the public and one for neuroimaging experts, suitable for delivery online or on paper. The public and expert surveys were modified to reflect the respondents' likely knowledge of and degree of personal relevance in determining their opinion on each issue. There were 10 questions in the public survey and 21 questions in the expert survey , websites , tweets , and science blogs as well as to attendees at meetings (e.g. Scottish Parliament Futures Forum) and societies for public engagement (Beltane http://www.publicengagement.ac.uk/about/beacons/edinburgh-beltane). The Expert Survey was distributed via university mailing lists , professional interest websites and individual imaging research centre websites) to target individuals who routinely used neuroimaging methods . Ethics approval was not sought. A level one self-assessment indicated that there was no risk to the respondent or the researcher.The survey was posted online, using the Survey Monkey Pro web survey template, between 31p<0.05). All available data were included. Percentages are based on samples of completed response, as opposed to the entire potential sample. After main effects were examined, we examined for trends within demographic profiles. The public sample was divided into groups based on scientific interest. The expert sample was divided based on the capacity in which they used neuroimaging technology .We used descriptive statistics to characterize the composition of the sample, t-tests to examine differences between the samples and chi-squared tests to analyse main effects and the majority described themselves as professionals (60%), students (16.5%), administrator (9.8%), not working (9.8%), skilled manual (2.7%) or manual workers (1.1%). The highest educational attainment was university undergraduate degree (30%), a Masters degree (21.3%), a PhD (15.9%), a professional qualification (15.5%), minimum school leaver's exam (8.9%) or final school leaver's exam (8.1%). Most respondents to the Expert Survey were neuroscientists (27%), followed by psychologists (17%), neuroradiologists (12.5%), psychiatrists (12.5%) or medical physicists (10.5%); had been using neuroimaging for 5\u201310 years (31%), <5 years (28%) or 10\u201320 years (26%); and were based in Scotland (34%), elsewhere in the United Kingdom (32%), Europe (16%) or the United States (15%).n\u200a=\u200a39, 5%) who said that their professions involve neuroimaging and may therefore not be representative of the public profile was identified, but no differences were found between the groups (p>0.05).Almost half the sample reported themselves as at least \u2018a little\u2019 aware of neuroimaging uses (47%), followed by \u2018quite aware\u2019 (26%), \u2018no awareness\u2019 (17%) and \u2018very aware\u2019 (10%).

Of those who reported using online sources, twitter and blogs were the most popular. When asked how often they encountered information on brain imaging, responses were highly varied with about a third reporting a little , often and very often .When asked about the regulation of brain imaging, most public respondents chose legislation (85%) and professional regulatory bodies (86%), followed by increased public awareness (84%). The least favoured response was the self-regulation of brain imaging research by the scientists themselves (53%), followed by the licensing of the scientists to conduct neuroimaging research (66%).Most expert survey respondents reported using neuroimaging for neuroscience research (66%), followed by clinical research (47%), medical diagnosis (35%), neuromarketing (4%), forensic purposes (3%) and security purposes (1%). The majority of respondents were aware of the use of neuroimaging outside traditional research (86%), particularly for neuromarketing (67%) and lie-detection (68%). Moderate awareness was reported for legal uses (48%), neuroaesthetics (56%), cognitive enhancement (55%) and mind reading (45%). Few were aware that neuroimaging was being used for security purposes (11%).Most respondents report specialist peer-reviewed literature as their main source of information on neuroimaging (84%), followed by general literature (65%), popular science media (50%), research conferences (54%), science blogs (25%), newspapers (25%) and popular science websites (23%).Most respondents thought that neuroimaging could improve the understanding of cognition , or improve treatment of psychiatric illness .

These vIn terms of strategies for regulating use of neuroimaging, respondents ranked professional guidelines first (66% ranked first or second choice), followed by more funding for interdisciplinary projects integrating neuroscience and law (50%) and improved public awareness (51%), with legal regulation (16%) and self regulation (15%) being placed last.A substantial majority (87%) felt that neuroimaging was not accurately portrayed in the media. When asked why, most cited poor journalism (54%) as either a quite or very important factor, followed by exaggerated results by researchers (51%), a lack of effective scientific communication (38%) and poorly conducted research (44%). Most respondents believe that increased exposure to neuroimaging research would raise its public profile as a beneficial technology (96%), whereas 80% foresaw a public backlash on the widespread use of the technology. 92% predicted an increase in funding opportunities, but 44% anticipated the opposite trend. 69% feared the over regulation of neuroimaging in research.Having said that, although most respondents thought it was important to communicate with the public (69%), most do not regularly engage with the media (52%). Of those that do communicate their results to the public, most used media and peer-reviewed publication to do this (78%), followed by public seminars (49%), the internet (39%) and television (28%). Among those that did not engage with the public, the majority gave little opportunity (58%), little incentive (38%) and distrust of media (27%) as their main reasons, followed by a lack of public speaking training (15%) and a fear of criticism (5%). When asked how this situation might be improved, most rated as \u2018quite\u2019 or \u2018very effective\u2019: professional credit for public engagement (75%), making public communication a funding requirement (72%), increased public exposure of research (76%), and outlets for a career in the media (25%).This survey of members of the public and neuroimaging experts revealed a range of similarities and differences of opinions. About a third of the public saw articles on neuroimaging in the media once or twice a month indicating, in line with previous research Although the public and experts were generally in agreement about some points, e.g. both had little faith in uses of neuroimaging in non-medical applications and both agreed on some methods to use for regulation, the results also suggest that extensive media coverage has moderated viewpoints and awareness differentially among the public and experts. The public were concerned about data protection issues. The experts had little awareness of how often neuroimaging had been used in court in the USA and one in three experts reporting no familiarity with neuromarketing or commercial lie-detection, although the public were aware of these uses. Although the experts thought that neuroimaging results were not well communicated in the media, and recognised the dangers of public loss of trust, few experts seemed motivated to improve the situation.Who can say which, if any, of the current legal, commercial or governmental uses of neuroimaging may become in future years routine, reliable tools? Neuroimaging is a rapidly evolving discipline; insights gained from well-conducted neuropsychological imaging research are in turn influencing knowledge of human behavioural traits on which many of society's attitudes are based. Consequently, it is entirely possible that society will need to adjust its views on behaviour, culpability, consciousness, etc. in future. However, a major focus of the present study was to determine how the public perceived the current capability of neuroimaging. Limited confidence in diagnosing psychiatric illness, lie-detection and neuromarketing was found, and to a far lesser degree in revealing racial and political attitudes and inner thoughts. Interestingly, the evidence base that complex social behaviours, such as racial attitudes and basic forms of mental representation, can be inferred using neuroimaging especially with regards privacy and human rights (e.g. \u201cAnything that is voluntary is acceptable. Mandatory brain scans are not\u2026\u201d). The public distrust of other technologies used to extract sensitive information for non-health related uses has been echoed in a public survey on the acceptability of genetic testing in insurance and employment settings One of the clearest trends identified in the survey is the public disapproval of the use of neuroimaging in non-medical or scientific settings, such as in marketing research, and in employment screening.

We used this measure of genetic effect modification to predict the expected difference in clinical benefit among KIF6 719Arg allele carriers and non-carriers in response to therapies that reduce LDL cholesterol. We then conducted a meta-analysis of statin trials to compare the expected difference in clinical benefit with the observed difference during treatment with a statin.In a meta-analysis involving 144,931 participants, the KIF6 719Arg allele was not associated with the relative risk (RR) of CVD . Meta-regression analysis involving 88,535 participants, however, showed that the 719Arg allele appears to influence the effect of LDL cholesterol on the risk of CVD. KIF6 carriers experienced a 13% greater reduction in the risk of CVD per mmol/L decrease in LDL cholesterol than non-carriers. We interpreted this difference as the expected difference in clinical benefit among KIF6 carriers and non-carriers in response to therapies that lower LDL cholesterol. The difference in clinical benefit predicted by the increased vulnerability to LDL cholesterol among KIF6 carriers agreed very closely with the observed difference among 50,060 KIF6 carriers and non-carriers enrolled in 8 randomized trials of statin therapy .The KIF6 719Arg allele increases vulnerability to LDL cholesterol and thereby influences the expected clinical benefit of therapies that reduce LDL cholesterol. A common single nucleotide polymorphism (rs20455) results in an argine to tryptophan substitution at position 719 (Trp719Arg) in the gene encoding kinesin-like protein 6 (KIF6). Some One possible explanation is that the KIF6 719Arg allele may increase the risk of cardiovascular disease (CVD), and that treatment with a statin may ameliorate this increased risk through a pleiotropic effect A biologically plausible hypothesis that can potentially reconcile these apparently conflicting findings is that the KIF6 719Arg allele may increase vulnerability to LDL cholesterol. If carriers of the 719Arg allele are more vulnerable to the deleterious effects of LDL cholesterol, then they should experience a greater increase in the risk of CVD per unit increase in LDL, and a correspondingly greater reduction in the risk of CVD per unit decrease in LDL, as compared to non-carriers. Therefore, if KIF6 carriers are more biologically vulnerable to LDL cholesterol, they should derive a greater clinical benefit per unit reduction in LDL cholesterol than non-carriers in response to therapies that lower serum LDL cholesterol levels.The primary aim of our study was to test the hypothesis that a common polymorphism can influence biological vulnerability to LDL cholesterol, and thereby influence the expected clinical benefit of therapies that reduce serum LDL cholesterol levels. To test this hypothesis, we first conducted a systematic review and meta-analysis of the association between the KIF6 719Arg allele and the risk of CVD. We then conducted a meta-regression analysis to measure the effect of the KIF6 719Arg allele on the association between LDL cholesterol on the risk of CVD. We used this measure of effect modification to estimate the expected difference in clinical benefit among KIF6 carriers and non-carriers in response to therapies that lower serum LDL cholesterol level. We then conducted a systematic review and meta-analysis of the effect of the KIF6 719Arg allele on the clinical efficacy of statin therapy. Finally, we compared the expected difference in clinical benefit predicted by the meta-regression analysis with the observed difference in clinical benefit among KIF6 carriers and non-carriers in the meta-analysis of statin trials.We searched Pubmed, Embase, Index of Science, HUGEnet, and Google Scholar, using the search terms: KIF6, rs20455, 719Arg, and Trp719Arg without language restriction; we also checked the abstracts and presentations from major cardiovascular medicine meetings held from 2004 to present First, we conducted an updated systematic review and meta-analysis of the association between KIF6 719Arg carrier status and the risk of CVD. For this analysis, we included case-control studies, epidemiologic cohort studies, and the treatment allocation arms of randomized trials of statin therapy that have reported data separately among KIF6 719Arg allele carriers and non-carriers, but excluded family-based studies. We included both the placebo allocation and statin allocation arms of the placebo controlled trials, as well as both the less intensive and more intensive treatment allocation arms of the trials that compared different treatment intensities of statin therapy. Each treatment allocation arm was considered as a separate prospective cohort study for the purposes of this analysis. For study samples that were included in more than one report, we used data from only the most recent report. In each study, Hardy-Weinberg equilibrium was assessed, as appropriate, using a chi-square test. For each prospective cohort study , we extracted the total number of KIF6 719Arg allele carriers and non-carriers, as well as the number of KIF6 carriers and non-carriers who experienced an incident CVD event during study follow-up. From each case-control study, we extracted the total number of prevalent cases and controls for both KIF6 719Arg allele carriers and non-carriers. We used these data to create 2\u00d72 tables to calculate the unadjusted relative risk (RR), and 95% confidence interval (CI), for each prospective cohort study, and the unadjusted odds ratio (OR), and 95% CI, for each case-control study (as an approximation of the RR) 2) by the effect modification was calculated as the difference in tau2 between the regression model with and without a regression term, expressed as a percentage.Next, we performed a random effects meta-regression analysis to measure the effect modification of study baseline LDL cholesterol level on the association between KIF6 carrier status (and separately KIF6 genotype) and the risk of CVD Finally, we conducted an updated systematic review and meta-analysis of statin trials that have reported results stratified by KIF6 carrier status (or KIF6 genotype). From the report of each randomized trial, we extracted data on the number of persons assigned to either treatment allocation arm and the number of incident CVD events that occurred during study follow-up in each arm, stratified by KIF6 carrier status. We used these data to create 2\u00d72 tables to calculate an unadjusted RR (and 95% CI) for the effect of statin therapy as compared to placebo (or more intensive statin therapy as compared to less intensive statin therapy) on the risk of incident CVD events, separately among KIF6 carriers and non-carriers in each study. All analyses were by the intent-to-treat principle. We then standardized the estimate of the effect of statin therapy per mmol/L reduction in LDL cholesterol across trials by multiplying the natural logarithm of the RR for each trial (and its standard error) by 1\u00f7 Y, where Y is difference in average LDL cholesterol during follow-up between the two treatment allocation arms . We then combined the adjusted RR for each trial using an inverse variance weighted random effects model We standardized the effect of statin therapy per mmol/L reduction in LDL cholesterol in order to compare the observed difference in clinical benefit in the meta-analysis with the expected difference in clinical benefit estimated from the meta-regression analysis using the same scale. Standardizing the effect of statin therapy also allowed us to include both the trials that compared statin with placebo and the trials that compared more intensive and less intensive statin therapy. In the meta-analysis, therefore, the primary measure of effect is not the clinical benefit of statin therapy per se, but rather the clinical benefit per mmol/L reduction in LDL cholesterol during treatment with a statin.2 metric Heterogeneity was measured using Cochran's Q, and the IA total of 37 case-control studies, prospective cohort studies, or randomized trial treatment allocation arms (each considered as a separate cohort), including 144,931 participants and 27,465 CVD events, were included in our meta-analysis of the association between the KIF6 719Arg allele and the risk of CVD [1]\u2013[6],2\u200a=\u200a58.7%).Among the 37 study samples included in our meta-analysis, 19 prospective cohort studies involving a total of 88,535 participants and 9,692 incident CVD events, provided information on the average baseline LDL cholesterol level of the population under study and therefore were included in our meta-regression analysis Relying on the symmetrical nature of the effect modification between any two epidemiologic exposures A total of 8 randomized trials, involving 50,060 participants and 7,307 incident cardiovascular events, were included in our meta-analysis of the effect of statin therapy, stratified by KIF6 carrier status [1]\u2013[6],The magnitude of the difference in clinical benefit per mmol/L reduction in LDL cholesterol observed among KIF6 719Arg carriers and non-carriers in response to treatment with a statin was nearly identical with the expected difference in clinical benefit per mmol/L reduction in LDL cholesterol predicted by the increased vulnerability to LDL cholesterol among KIF6 719Arg carriers from the meta-regression analysis .Our study demonstrates that the common KIF6 719Arg allele appears to increase vulnerability to LDL cholesterol, and thereby influences the expected clinical benefit from therapies that lower serum LDL cholesterol levels. Persons who inherit one or more copies of the 719Arg allele appear to be more biologically vulnerable to the deleterious effects of LDL cholesterol than non-carriers. As a result, KIF6 719Arg carriers appear to derive a greater reduction in the risk of CVD per mmol/L reduction in LDL cholesterol than non-carriers. The results of our study resolve several apparently conflicting lines of evidence to provide a biologically plausible explanation for how KIF6 carriers can derive a greater clinical benefit from treatment with a statin than non-carriers, even though this polymorphism does not have any impact on the LDL cholesterol lowering effect of statins, and is not independently associated with the risk of CVD.More generally, our study demonstrates that a common polymorphism can influence vulnerability to LDL cholesterol, and thereby influence the expected clinical benefit from therapies designed to lower serum levels of LDL cholesterol. The concept of genetically-mediated differential vulnerability to LDL cholesterol is illustrated in Our study shows that, on average, KIF6 719Arg allele carrier status is not associated with the risk of CVD. Our study also shows, however, that this association varies significantly according to the average baseline LDL cholesterol level of the population under study . FurtherOur findings do not challenge the results of a large-scale meta-analysis of statin randomized trials that found that the clinical benefit of statin therapy is determined largely by the magnitude of LDL cholesterol reduction achieved during treatment Importantly, our study shows that the KIF6 719Arg allele increases vulnerability to LDL cholesterol even though it is not, on average, associated with an increased risk of CVD. This means that all 2.5 million directly genotyped and imputed polymorphism measured in previously conducted genome-wide association studies of CVD, very few of which have been shown to be reliably associated with the risk of CVD Our study has several limitations. Most importantly, we did not have any data on the association between LDL cholesterol and the risk of CVD, stratified by KIF6 carrier status. Therefore, we could not estimate the effect modification of KIF6 on the association between LDL cholesterol and the risk of CVD directly. Instead, we estimated this effect from the meta-regression estimate of the effect modification of LDL cholesterol on the association between the KIF6 719Arg allele and the risk of CVD. We believe this approach is valid because these two estimates of effect modification are equivalent as shown in In conclusion, we found that the common KIF6 719Arg allele appears to increase vulnerability to LDL cholesterol, and thereby influences the expected clinical benefit from therapies that lower serum LDL cholesterol levels. More generally, our study demonstrates that a common polymorphism can influence vulnerability to a common modifiable risk factor for CVD even if it is not independently associated with the risk of CVD. Our study provides a roadmap for further research that could potentially lead to the discovery of polymorphisms that cause large differences in vulnerability to common modifiable risk factors for CVD and thus lead to correspondingly large differences in the clinical benefit derived from therapies used to treat these risk factors. Incorporating such polymorphism into the care of individual patients may help to guide the selection of optimal medical therapies for each individual person based on their genetic background and therefore introduce a practical clinical strategy to personalize the prevention of CVD.Table S1A list of studies included in the meta-analysis of the KIF6 719Arg allele and the risk of cardiovascular disease.

We investigate causal links between a dramatic faunal turnover and two dominant geologic processes operating within Laurentia during the Late Ordovician: the Taconian Orogeny and GICE related global cooling. We utilize a novel approach for elucidating the relationship between biotic and geologic changes using a time-stratigraphic, species-level evolutionary framework for articulated brachiopods from North America. Phylogenetic biogeographic analyses indicate a fundamental shift in speciation mode\u2014from a vicariance to dispersal dominated macroevolutionary regime\u2014across the boundary between the Sandbian to Katian Stages. This boundary also corresponds to the onset of renewed intensification of tectonic activity and mountain building, the development of an upwelling zone that introduced cool, nutrient-rich waters into the epieric seas of eastern Laurentia, and the GICE isotopic excursion. The synchronicity of these dramatic geologic, oceanographic, and macroevolutionary changes supports the influence of geologic events on biological evolution. Together, the renewed tectonic activity and oceanographic changes facilitated fundamental changes in habitat structure in eastern North America that reduced opportunities for isolation and vicariance. They also facilitated regional biotic dispersal of taxa that led to the subsequent establishment of extrabasinal (=invasive) species and may have led to a suppression of speciation within Laurentian faunas. Phylogenetic biogeographic analysis further indicates that the Richmondian Invasion was a multidirectional regional invasion event that involved taxa immigrating into the Cincinnati region from basins located near the continental margins and within the continental interior. Late Ordovician (~450 Ma) shallow marine deposits of Laurentia record a series of dramatic faunal and biogeographic shifts including a rapid change from predominantly warm to cool water adapted taxa during the middle Mohawkian (late Sandbian) and a major regional biotic immigration event into the Cincinnati Basin during the early Richmondian (Katian) ,2. TheseDuring the Late Ordovician, the Taconian orogeny developed along the eastern margin of Laurentia as a result of diachronous collisions with an island arc and/or microplates \u20135 , carbonate deposits of eastern Laurentia reflect a heterozoan assemblage typified by cool water and/or non-photosynthetic organisms, whereas tropical-style carbonates became restricted to the continental interior and marginal basins ,7. This sequenceAlso during the M5 sequence, faunas of the Appalachian Basin transitioned from predominantly warm to cool water adapted. The biotic overturn was accomplished primarily through immigration of extra-basinal taxa into a region following regional generic extinction . For exaThe Richmondian Stage was employed as described in Wiley & Lieberman . SpeciesBecause different geologic processes operated before and after the M4/M5 sequence boundary, LBPA was employed in a time-stratigraphic framework to more accurately discern patterns of biogeographic differentiation. Stratigraphic dimension was incorporated based on equal phylogenetic split using first and last appearances of species at the level of depositional sequence. Cladogenetic events were separated into Time Slice 1 (T1), approximately corresponding to the Blountian tectophase (W-b through M4 sequences), and Time Slice 2 (T2), approximately corresponding to the Taconic tectophase (M5 though C6 sequences) . AdditioGlyptorthis indicates that the genus originated in the Southern Midcontinent region and subsequently underwent a major dispersal event into the Appalachian and Central Basins with frequent episodes of speciation via dispersal into neighboring tectonic basins during T2 , whereas the other tree is consistent with a more recent exchange of taxa between Anticosti Island and the Midcontinent region (supported by biogeographic affinities of Psubquadratus. ). These data indicate that both dispersal pathways were operational during the Richmondian Invasion.The diametrically opposed patterns of speciation and biogeographic differentiation between T1 and T2 reflect different biogeographic controls operating before and after the M4/M5 sequence boundary. This discrepancy is clearly illustrated by the divergent topology of vicariance trees between times slices and the dissimilarity of the geodispersal and vicariance trees within each time slice , 3. The The level of congruence between vicariance and geodispersal trees is indicative of the style of geologic processes impacting macroevolutionary patterns . CongrueDuring T1, the Blountian tectophase introduced siliciclastics into eastern Laurentia yet did not inhibit the production of tropical carbonates ,6. The hDispersal became the dominant mode of speciation during the Taconic tectophase of the Taconian Orogeny T2). The combination of flexural downwarping of the craton and GICE related oceanographic changes facilitated the upwelling of cool, nutrient rich water into the shallow epieric seas of eastern Laurentia ,5,9. Thi. The comThe shift in speciation regime across the M4/M5 boundary is significant because high rates of vicariance are typically associated with high rates of speciation, whereas high rates of dispersal are associated with reduced speciation . The negThe main pulse of the Richmondian Invasion into the Cincinnati Basin occurred during the C5 sequence . The retPhylogenetic biogeographic analysis of species-level patterns in Middle to Late Ordovician brachiopods indicates a shift in biogeographic patterns and macroevolutionary dynamics between the Blountian and Taconic tectophases of the Taconian orogeny . These patterns were driven largely by geologic processes related to the Taconian Orogeny and global cooling at the boundary between the Sandbian and Katian stage boundary (M4/M5 sequence boundary). Prior to the M5 sequence, tectonic activity associated with the Blountian tectophase produced increased habitat fragmentation in tropical carbonate environments, thereby facilitating high levels of vicariant speciation. In contrast, the post-M5 sequence interval corresponds to a shift in paleoceanographic conditions related to the combined effect of structural deformation from the Taconic tectophase and GICE related global cooling, whereby cool, nutrient rich water from the Sebree Trough was introduced into shallow intracratonic seas. Dispersal became the dominant form of speciation and the increased number of invasive species may have led to increased faunal homogenization between basins. High rates of dispersal in the T2 interval and a return to tropical conditions within the Cincinnati Basin facilitated the Richmondian Invasion into the Cincinnati Basin. Species-level phylogenetic biogeographic patterns suggest both intracratonic seas and marginal basins supplied invasive species into the Cincinnati Basin.Figure S1The division between TS1 and TS2 is indicated by the horizontal line.(TIF)Click here for additional data file.Table S1Numbered columns refer to nodes and tips on the stratocladograms .

Brain volumetric measurements were also performed to assess the extent of central nervous system involvement and whether this correlated with the development of extraocular neurological features in patients with CPEO+ phenotypes.The study cohort included: (i) nine patients with single, large-scale mtDNA deletions \u200a=\u200a3.0 years), (ii) eleven patients with multiple mtDNA deletions , and (iii) ten age-matched normal controls Table 1.POLG mutations (n\u200a=\u200a4) PEO1 mutations (n\u200a=\u200a3) OPA1 mutations (n\u200a=\u200a1) RRM2B mutations (n\u200a=\u200a1) c oxidase-deficient fibres in addition to prominent ragged red fibres.All patients were assessed by an experienced multi-disciplinary team of neurologists and ophthalmologists to define the clinical phenotype and disease severity Table 1.Text S1), with a high degree of intra- and inter-observer reliability (Table S1).MRI and MRS data were acquired on a 3-Tesla Philips Achieva clinical MR system using an 8-channel head coil. Proton MRS analysis was performed by an experienced research physicist (FES) to derive brain metabolite concentrations in the parietal white matter and brainstem regions: (i) choline; (ii) creatine; (iii) total glutamate and glutamine (Glx); (iv) myo-inositol; and (v) N-acetyl-aspartate (NAA). Extraocular and brain compartment volumes were measured using standardised semi-automated segmentation protocols . Group comparisons were made using the unpaired t-test. Intra-observer and inter-observer variability for the measurement of extraocular muscle and brain volumes was assessed with Pearson correlation coefficient (r). and and There was a significant reduction in extraocular muscle volumes in the CPEO group compared with normal controls for all four recti muscles Figure 1There was no significant difference in metabolite concentrations between the patient and control groups in both the parietal white matter and brainstem voxels Table 4.Carlow and colleagues observed a significant reduction in extraocular muscle volumes for the inferior rectus, medial rectus and lateral rectus Ortube and colleagues measured extraocular muscle volumes in five patients with a clinical diagnosis of CPEO Ortube and colleagues, including the relatively small number of patients that were recruited and the lack of a confirmatory molecular diagnosis. Furthermore, only a relatively small portion of the extraocular muscle belly was sampled, which could have underestimated the degree of atrophy in the recti muscles.This study has shown clear evidence of significant extraocular muscle atrophy involving all four recti muscles in CPEO. This striking observation was noted for both patients with single, large-scale mtDNA deletions and for those harbouring multiple mtDNA deletions secondary to an underlying nuclear genetic defect. In a previous report of nine patients with CPEO, Our study is the first to demonstrate objectively that the extent of extraocular muscle atrophy in CPEO is highly symmetrical between the two eyes of the same patient, reflecting the ophthalmoplegia pattern observed clinically A variable decrease in N-acetyl-aspartate (NAA) has previously been reported in the brain of patients with the Kearns-Sayre syndrome \u2013 a particularly severe clinical phenotype characterised by the development of CPEO and pigmentary retinopathy before the age of twenty years, often in association with progressive cardiac conduction block Patients with CPEO+ features had significantly reduced total grey matter and cerebellar volumes compared with controls, in keeping with the higher burden of neurological disease in this specific patient population. The prominent degree of atrophy seen in the cerebellum further highlights the particular vulnerability of this specific brain region to the deleterious consequences of mtDNA defects This comprehensive magnetic resonance study of patients with molecularly confirmed CPEO has revealed a number of important findings that are directly relevant to our understanding of the underlying pathophysiology in this mitochondrial ocular disorder. In addition to marked generalised extraocular muscle atrophy, there was clear evidence of significant CNS involvement in this disorder, which becomes clinically manifest in a subgroup of patients.Figure S1Voxel placements and proton magnetic resonance spectra.(PDF)Click here for additional data file.Figure S2Boundary delineation of extraocular muscle cross-sections.(PDF)Click here for additional data file.Figure S3Measurement protocol for brainstem and cerebellar volumes.(PDF)Click here for additional data file.Table S1Validation of extraocular muscle and brain volume measurements.(DOC)Click here for additional data file.Text S1Supplementary methods.(DOC)Click here for additional data file."} +{"text": "Malaria prevalence has recently declined markedly in many parts of Tanzania and other sub-Saharan African countries due to scaling-up of control interventions including more efficient treatment regimens (e.g. artemisinin-based combination therapy) and insecticide-treated bed nets. Although continued molecular surveillance of malaria parasites is important to early identify emerging anti-malarial drug resistance, it is becoming increasingly difficult to obtain parasite samples from ongoing studies, such as routine drug efficacy trials. To explore other sources of parasite DNA, this study was conducted to examine if sufficient DNA could be successfully extracted from malaria rapid diagnostic tests (RDTs), used and collected as part of routine case management services in health facilities, and thus forming the basis for molecular analyses, surveillance and quality control (QC) testing of RDTs.Plasmodium species detection. Additionally, 165 archived RDTs obtained from ongoing malaria studies were analysed to determine the amplification success and test applicability of RDT for QC testing.One hyper-parasitaemic blood sample was serially diluted in triplicates with whole blood and blotted on RDTs. DNA was extracted from the RDT dilution series, either immediately or after storage for one month at room temperature. The extracted DNA was amplified using a nested PCR method for DNA was successfully extracted and amplified from the three sets of RDT dilution series and the minimum detection limit of PCR was <1 asexual parasite/\u03bcl. DNA was also successfully amplified from (1) 70/71 (98.6%) archived positive RDTs (RDTs and microscopy positive) (2) 52/63 (82.5%) false negative RDTs (negative by RDTs but positive by microscopy) and (3) 4/24 (16.7%) false positive RDTs (positive by RDTs but negative by microscopy). Finally, 7(100%) negative RDTs (negative by RDTs and microscopy) were also negative by PCR.This study showed that DNA extracted from archived RDTs can be successfully amplified by PCR and used for detection of malaria parasites. Since Tanzania is planning to introduce RDTs in all health facilities , availability of archived RDTs will provide an alternative source of DNA for genetic studies such as continued surveillance of parasite resistance to anti-malarial drugs. The DNA obtained from RDTs can also be used for QC testing by detecting malaria parasites using PCR in places without facilities for microscopy. Malaria has for a long time remained a major cause of morbidity and mortality in most endemic countries particularly in sub-Saharan Africa. However, recent reports have indicated that malaria prevalence has declined drastically in some endemic countries -4.

Archived RDTs were obtained from ongoing studies in Muheza and Korogwe . Other 94 RDT samples (on ParaHIT\u00aef), included 24 RDT false positive (positive by RDT but negative by microscopy), 63 false negatives (negative by RDTs but positive by microscopy) and seven negative samples (negative by both RDTs and microcopy) obtained from a cross-sectional survey conducted in May 2010 in four villages in Muheza district where high level of false positive and negative RDT results were observed in previous surveys . All 165 RDT samples were stored at room temperature in the field or laboratory for a duration of 6 - 95 days (Table The archived RDT samples included 71 RDTs (positive for both RDT and microcopy) collected at health facilities in Muheza and Korogwe districts and stored without any preservatives at room temperature (temperature ranging from 25 - 34\u00b0C).

However, because of this current positive trend, recruitment of malaria positive patients for various studies, such as malaria drug efficacy trials has proved to be difficult. Since the region has been known as a hotspot for the emergence of anti-malarial drug resistance in Eastern Africa [Previously, malaria has consecutively been shown to be the main cause of morbidity and mortality in Tanga region, as for the rest of Tanzania -31. Howen Africa -36, it iIn this context, the study presented here has shown that archived RDTs used for malaria diagnosis in routine practice can be used as an alternative source of DNA for detection of malaria parasites and other molecular analyses. The RDTs can also be used as source of DNA as part of QC testing of RDTs instead of microscopic examination of Giemsa-stained blood smears, by comparing RTD results produced by health workers with those obtained in the laboratory based on detection of malaria parasite by PCR. Thus, after deployment of RDTs in the field, archived RDTs can also be used for QC of RDTs in addition to using Giemsa-stained blood smears, particularly in health facilities without capacity for performing malaria diagnosis by microscopy or lacking the skills and experience to prepare good blood smears as recently shown in Eastern Tanzania by McMorrow and colleagues ,25.Storage of RDTs (that were prepared in the laboratory) for one month either with or without silica gel as preservatives did not affect the quality of extracted DNA as determined by the detection limit of PCR in the diluted samples and band intensity of amplified products in comparison to known standard DNA samples which were used as control. Similarly, field samples stored at room temperature without preservatives for over 3 months were equally amplified. However, the impact of long term storage of RDTs beyond this duration on the quantity and quality of DNA is not clearly known, particularly if they are stored at room temperature without preservatives and under high ambient temperature, and humidity (as in most parts of Tanzania) which support growth of moulds that can degrade the parasite DNA.

Furthermore, the RDTs can be used for QC testing of RDTs deployed in the field for malaria diagnosis based on comparing the results obtained by PCR genotyping of DNA extracted from archived RDTs with the test results produced by health workers, particularly from remotely located health facilities without the capacity of microscopic examination of blood smears. Thus, availability of archived RDTs after the tests are deployed in all health facilities in Tanzania as planned by the Ministry of Health and Social Welfare will provide a good source of parasite DNA for laboratory studies.Plasmodium falciparum; PfHRP-2: Plasmodium falciparum histidine rich protein 2; RDTs: Rapid diagnostic tests; WBCs: white blood cells; WHO: World Health Organisation; \u03bcl: microlitre.ACT: artemisinin combination therapy; DNA: deoxyribonucleic acid; pLDH: Plasmodium lactate dehydrogenase; NIMR: National Institute for Medical Research; NMCP: National Malaria Control Programme; PCR: polymerase chain reaction; Pf: The authors declare that they have no competing interests.DSI, MA conceived of the study, designed the experiments, supervised the laboratory analyses and wrote the manuscript.

Intra-specific recombination has been proposed as an important, but underestimated, driving force in herpesvirus evolution. Recently, two distinct field strains of infectious laryngotracheitis virus (ILTV) have been shown to have arisen from independent recombination events between different commercial ILTV vaccines. In this study we sequenced the genomes of additional ILTV strains and also utilized other recently updated complete genome sequences of ILTV to confirm the existence of a number of ILTV recombinants in nature. Multiple recombination events were detected in the unique long and repeat regions of the genome, but not in the unique short region. Most recombinants contained a pair of crossover points between two distinct lineages of ILTV, corresponding to the European origin and the Australian origin vaccine strains of ILTV. These results suggest that there are two distinct genotypic lineages of ILTV and that these commonly recombine in the field. Herpesviridae have genomes ranging in size from 124 to 241 kbp Alpha-, Beta- and Gammaherpesvirinae. Classically, sequences obtained from a single gene or multiple concatenated genes have been used for phylogenetic analyses of herpesviruses. More recently developments in high-throughput sequencing techniques have resulted in the availability of complete genome sequences for comparative complete genomic analyses of herpesviruses Herpesviruses are highly host-specific double stranded DNA viruses that have been isolated from most animal species, including mammals, birds, reptiles and fish. The Alphaherpesvirinae (genus Iltovirus) and causes acute upper respiratory tract disease in chickens Iltovirus genus (including psittacid herpesvirus 1 (PsHV1) and ILTV) separated from the mammalian alphaherpesviruses around 200 million years (Mys) ago, in agreement with the theory that herpesviruses have co-evolved with their hosts AlphaherpesvirinaeInfectious laryngotracheitis virus belongs to the subfamily In Australia three commercial live ILTV vaccines are registered for use. The SA2 vaccine strain is an attenuated ILTV field strain isolated from South Australia in 1950 Australian ILTV field strains and vaccine strains have been classified into nine genotypes (classes 1 to 9) using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis th century) In a previous report we analysed and compared the complete genome sequences of two Australian origin ILTV vaccines and a European origin ILTV vaccine strain. The genome sequences of the two Australian origin vaccines differed by only 23 nucleotide substitutions, even though one of the strains was derived from the other after more than twenty-five serial passages in cell culture and embryonated eggs. Although similar to each other, these two Australian vaccine strains showed considerable divergence (0.8% nucleotide difference) from the genomic sequence of the European origin ILTV vaccine strain. This is higher than the 0.1\u20130.5% nucleotide difference reported between the most distantly related strains of varicella zoster viruses (VZV), which is a human alphaherpesvirus with the same genomic sequence arrangement as ILTV The aim of this study was to better understand the molecular epidemiology of ILTV by analysing a broader range of ILTV sequence data, including currently available complete or partial genomic sequences of ILTV. The complete genome sequences of two Australian ILTV field strains (V1-99 and CSW-1) were determined using high-throughput sequencing and included in these analyses. Additionally, we aimed to identify the origins of the parent strain of the Australian ILTV vaccines by searching for similar genotypes among publically available nucleotide sequences from ILTV strains isolated in other countries.de novo and mapped to the complete genome sequence of the Serva vaccine strain. Sequence gaps were filled and ambiguous sequences clarified using Sanger sequencing. The size of the ILTV genomes ranges from 150,335 to 153,952 bp . The size of the strain V1-99 genome was 153,631 bp, similar to that of the Serva strain . The V1-99 and Serva strains shared 99.6% nucleotide sequence identity. The CSW-1 strain genome was somewhat smaller due to three large deletions within the unique long region and both the internal and terminal repeat regions (463 bp) (Sequencing data from the V1-99 and CSW-1 strains of ILTV obtained by high-throughput sequencing were assembled (463 bp) . Excludi(463 bp) .In order to further understand the relationship between ILTV vaccine strains and Australian field strains of ILTV, complete genome sequence alignments were performed and phylogenetic trees were inferred using the six complete genomic sequences of ILTV currently available. This analysis included a European origin vaccine (Serva), an Australian origin vaccine (SA2), two Australian field strains (V1-99 and CSW-1) and two strains from the USA (63140 and USDAref). The sequences were examined in order to identify relevant genes that could be used to differentiate between all six strains .All predicted ORFs were extracted from the complete genome alignments and separate phylogenetic trees were inferred from the nucleotide sequences of each ORF. Similarly, alignments of amino acid sequences for all the predicted ORFs were performed separately and phylogenetic trees were inferred. The UL21, 32, 34 and 43 genes of all six ILTV strains were found to share 100% nucleotide and amino acid sequence identity. The UL3, 4, 13, 14, 18, 24, 31, 33, 40 and 49 genes of the six strains had differing nucleotide sequences, but were predicted to have 100% amino acid sequence identity. The ICP4, UL27, UL36, US5 and US8 genes showed the most variability within the six strains of ILTV and the six strains could be distinguished using the nucleotide and/or amino acid sequences of these genes . The UL2All available nucleotide sequences for the ICP4 and UL27 genes of ILTV from the NCBI database were aligned and phylogenetic analyses were performed . The EurTo confirm the close relationship between the Australian origin vaccine strain and strains isolated from backyard flocks in the USA, concatenated nucleotide and amino acid sequences were generated using all available sequences for each of these strains. This included the complete sequences of the UL27, UL32 and UL10 genes from the unique long region, the UL47 and US4 genes from the unique short region, and the complete sequence of the ICP4 gene from the repeat region. Surprisingly, one of the strains isolated from backyard flocks in the USA (25/H/88/BCK) shared 100% amino acid sequence identity with the concatenated sequence of the Australian origin vaccine. Another strain isolated from backyard flocks in the USA (12/D/02/BCK) differed in only two amino acid residues from the Australian origin vaccine strain . These rA possible mosaic pattern of relationship between the genome sequences of the Australian field strains of ILTV was detected in the phylogenetic analyses of the UL27 and ICP4 genes . In addiTo confirm the mosaic patterns of these relationships and detect the suspected recombination events responsible, we performed additional phylogenetic analyses on the nucleotide sequences of the UL47 and US4 genes . As expeIn order to define recombination crossover points, Bootscan analyses were performed using complete genome alignments of five ILTV strains . Bootscan analyses of the 1874C5 and CSW-1 strains revealed pairs of crossover points in the repeat region, while the 81658 strain had multiple tightly grouped pairs of crossover points in the unique long region . Most ofA history of recombination was not detected in the sequences located in the unique short region of the genome of the eight strains of ILTV for which complete genomic sequence was available, so the sequences of this region were used to investigate the evolutionary history of ILTV. In the resulting trees, all Australian strains of ILTV clustered together and separately from European and USA strains of ILTV . The timin vivo. In this study, we sought to perform broader phylogenetic analyses of ILTV in order to understand the evolution and molecular epidemiology of the virus. We found that the parent strains of Australian origin vaccine and Australian field strains may have been imported into Australia from the USA. Moreover, with the exception of field isolates derived from bird-to-bird passage of commercial vaccines, most field strains of ILTV isolated in Australia and in other geographic areas of the world show evidence of historical recombination events between two distinct viral lineages, represented by the Serva and SA2 strains.Genome wide comparative sequence analyses of closely related strains of ILTV, or of strains from specific geographical regions, have been reported previously The Australian origin SA2 vaccine was produced using an Australian field isolate that induced comparatively smaller pocks on the chorioallantoic membrane of embryonated hen eggs In order to search for an SA2-like strain of ILTV in other geographical areas, we compared the phylogenetic tree inferred from alignments of complete genome sequences with those inferred from alignments for all individual predicted ORFs. The ICP4, UL27, UL36, US5 and US8 genes were found to be sufficiently divergent to allow differentiation between distinct strains of ILTV . ComparaThe European origin Serva vaccine strain was recently registered in Australia and rapidly became widely used by the Australian poultry industry within a relatively short timeframe The Australian field strains V1-99 and CSW-1 and the USA field strain 874C5 shared a distinct sequence segment in the unique long region. This suggests that the Australian field strains and the 1874C5 strain may have shared the same (or very similar) parent strain(s) before recombination, or that these strains may have obtained this distinctive sequence segment from some other strain in independent recombination events.Evidence of historical intra-specific recombination in alphaherpesviruses has been described previously With the exception of the USDAref and 81658 ILTV strains, which each contained three recombination crossover points, all other ILTV recombinants contained a single pair of recombination crossover points between the Serva-like and the SA2-like parental strains, as detected by bootscan analyses. Recombination networks further supported these findings, confirming that recombination events occurred in the unique long and the repeat regions, but not in the unique short region and 7. TIn conclusion, the origins of Australian strains of ILTV have been determined using complete genomic sequence analyses of multiple strains of ILTV and wider phylogenetic analyses. Moreover, evidence for significant recombination events in most field strains of ILTV was identified by recombination network and bootscan analyses. We found that the Serva-like and SA2-like lineages of ILTV have recombined frequently over the history of ILTV evolution. This, taken together with data from our previous studies Pock purified V1-99 (six passages from isolation) and a laboratory stock of CSW-1 ILTV (approximately twenty passages from isolation) de novo assembled contigs and to produce a consensus sequence using the Serva ILTV genomic sequence (Genbank accession HQ_630064) as reference. Any sequence gaps or ambiguous regions of sequence were confirmed by Sanger sequencing using BDT version 3.1 (Applied Biosystems).

However, whether or not elements of the local climate that are relevant for cholera transmission have stationary signatures of the IOD on their dynamics over different time scales is still not clear. Here we report results on the time-varying relationships between the various remote and local environmental drivers and cholera incidence in Bangladesh.We performed a cross wavelet coherency analysis to examine patterns of association between monthly cholera cases in the hospitals in Dhaka and Matlab (1983\u20132008) and indices for both IOD and ENSO. Our results showed that the strength of both the IOD and ENSO associations with cholera hospitalizations changed across time scales during the study period. In Dhaka, 4-year long coherent cycles were observed between cholera and the index of IOD in 1988\u20131997. In Matlab, the effect of ENSO was more dominant while there was no evidence for an IOD effect on cholera hospitalizations.Our results call for the consideration of non-stationary, possibly non-linear, patterns of association between cholera hospitalizations and climatic factors in cholera epidemic early warning systems. Vibrio cholerae, the bacterium that causes the disease, is known to inhabit riverine, estuarine and coastal ecosystems with specific abiotic and biotic components V. cholerae has an increased growth rate in aquatic environments with warmer temperatures, particularly when combined with a high pH and blooms of phytoplankton, aquatic plants or algae Cholera remains a major public health problem in many places, including Bangladesh, India, and a number of countries in Africa and South America V. cholerae multiplication It has been reported that the El Ni\u00f1o-Southern Oscillation (ENSO) plays a role in the interannual variation of endemic cholera in Bangladesh The Indian Ocean Dipole (IOD) is another climate mode that arises from ocean-atmosphere interactions that cause interannual climate variability in the tropical Indian Ocean Wavelet analysis is useful for epidemiological time series analyses mainly because of the non-stationarity of associations between the disease dynamics and exposure covariates Dhaka: The ICDDR,B hospital serves a large urban population within the city of Dhaka and provides free treatment for more than 100,000 cases of diarrhea each year. A surveillance system was established at the ICDDR,B in 1979 to systematically sample children and adults with diarrheal illnesses th patient was enrolled in the surveillance system, and since 1996 every 50th patient has been enrolled. Matlab. Matlab is a rural and riverine delta area situated approximately 57 km southeast of Dhaka. Every hospital visit of patients residing within the area covered by the Health and Demographic Surveillance System (HDSS), which consists of 142 villages with populations over 220,000, was registered in the hospital surveillance system The primary outcome for this study was the monthly number of patients with cholera who attended the International Centre for Diarrhoeal Disease Research, Bangladesh hospitals in Dhaka and Matlab . Dhaka: V. cholerae. The details of the laboratory procedures were described in a previous study V. cholerae of the serogroups O1 or O139 was identified in the stool specimen, regardless of the presence of other pathogens. From the surveillance data that had been collected over a 26-year period (January 1983 to December 2008) for Dhaka and 28-year period (January 1981 to December 2008) for Matlab, we retrieved the date of the hospital visit and the pathogens identified in each stool specimen. From these data, the monthly cholera cases in Dhaka and Matlab were counted separately and used for analysis.For each diarrhea patient of the ICDDR,B hospitals in Dhaka and Matlab, the stool was microbiologically examined to identify common enteric pathogens including www.jamstec.go.jp/frcgc/research/d1/iod/). The DMI values were calculated using the SST data from the HadISST dataset (http://www.metoffice.gov.uk/hadobs/hadisst/). The base period for calculating anomalies was 1958\u20132008. These values were standardized to zero mean and unit standard deviation. The strength of the ENSO was measured by monthly average SSTs in the Ni\u00f1o 3 region (Nino3) in the Pacific Ocean that we derived from the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center data (http://www.cpc.ncep.noaa.gov). We examined the association between DMI and monthly average SST in the northern Bay of Bengal to gain some insight into the causal pathways linking the IOD to the number of cholera cases. Mean monthly SSTs in the Bay of Bengal were derived from the NOAA Optimum Interpolation Sea Surface Temperature dataset The strength of the IOD was measured by the dipole mode index (DMI), defined as the difference in SST between the western and eastern tropical Indian Ocean The daily rainfall and maximum and minimum temperature data for Dhaka and Matlab were obtained from the Bangladesh Meteorological Department. The data for the daily river levels of the Brigonga (Millbarrak in Dhaka) and Danagoda (Matlab Bazaar) rivers were obtained from the records maintained by the Bangladesh Water Development Board. The monthly means for the maximum temperature (\u00b0C) and maximum river level (m), and the total monthly rainfall (mm) were calculated from the daily records. Missing values (17 [5.4%] in Dhaka and 6 [1.9%] in Matlab) for river levels were imputed using the average values of the same month in the other years over the whole time series.Temporal patterns of association in the time series were studied using the continuous wavelet transform 0\u200a=\u200a6 months , a total smoothing window of 31 and parameter W0\u200a=\u200a6 (dimensionless parameter of the Morlet Wavelet). Further details about cross wavelets and software are described in Maraun and Kurths V. cholerae El Tor O1 biotype strain and one for the O139 Bengal strain.We also estimated the cone of influence, where inferences from the wavelet analysis outside the cone of influence are not valid because of the manipulations that were performed to generate the wavelet spectrum in the absence of data for larger period frequencies We did not stratify the analysis by age, because the seasonal patterns were the same and there was no likely reason to expect different cholera-climate associations between the age groups at interannual time scales.The associations between DMI, Nino3 and monthly average temperature, rainfall and SST in the northern Bay of Bengal were also examined by wavelet coherence analysis. All the analyses were performed with R software (version 2.0).The time series for the number of cholera patients per month, by serogroup and biotype, ambient temperature, rainfall and river level during the study period are shown for Dhaka and MatlThe time series for Dipole Mode Index (DMI), Nino3 and sea surface temperature (SST) during the same period are shown in Four-year long coherent cycles between O1 cholera and DMI were seen in 1988\u20131997 in Dhaka while thV. cholerae were similar to the result for the El Tor O1 biotype strain alone because the frequency of the O1 biotype was dominant during the study period in the Bay of Bengal The association between Dipole Mode Index (DMI) and cholera hospitalizations that we found in Dhaka was not observed in Matlab, while a consistent association between Nino3 and cholera hospitalizations was observed only in Matlab. The associations that we found between DMI and Nino3 with cholera are broadly consistent with previous finding There are some limitations in this study. First, less severe cases of cholera are less likely to have been included in the surveillance data; however, this should not pose a threat to the validity of the comparison over time, which was the subject of this study. Second, some cases could have been missed because of limitations in the capacity of the hospitals to receive the patients; particularly, during epidemics of cholera. However, in principle, the hospitals accept all patients who visit the hospital. Thus, the capacity of the hospitals should not be an important limitation of this study. Third, the wavelet analysis explores a periodical synchronicity between two time series, and so has no bearing on mechanisms. Further environmental and microbiological studies are necessary to elucidate the causal pathways of the associations.Because of the serious global consequences of cholera and its sensitivity to climate, the World Health Organization has proposed that an early warning system for cholera epidemics using climatic parameters could be developed Figure S1Monthly time series of cholera hospitalizations by (a) serotype O1 & O139 and (b) bio-type El Tor & Classical for Dhaka (January 1983\u2013December 2008).(TIF)Click here for additional data file.Figure S2Monthly time series of cholera hospitalizations by (a) serotype O1 & O139 and (b) bio-type El Tor & Classical for Matlab (November 1981\u2013December 2008).(TIF)Click here for additional data file.Figure S3Cross wavelet coherence of global and local climatic time series with cholera in Dhaka and Matlab.

Hypertrophic cardiomyopathy (HCM) is the most common cause of SCD among the young patients. SCD is often the first manifestation of the disease. There are 5 major risk factors for SCD in patients with HCM. However, no single risk factor can be used as a screening test in assessment of SCD. Nowadays new non-invasive risk factors, such as T-wave alternation (TWA), are being studied. They may provide important information on the patient\u2019s susceptibility to life threatening arrhythmias.The study involved 33 hypertensive heart disease (HHD) patients and 22 HCM patients. All patients underwent echocardiography test (ECHO) and 24h Holter monitoring with mTWA evaluation using the modified moving average method. The evaluation involved maximum mTWA figures in 24h (mTWA max), mTWA figures at the heart rate of 100/min (mTWA 100) and at 5:00 am (mTWA 5:00).The common group demonstrated a weak direct correlation between the thickness of ventricular septum (IVSth) and mTWA max, as well as a weak reverse correlation between the left ventricular posterior wall thickness (LVPWth) and mTWA 100. These correlation were revealed primarily in HHD patients who demonstrated correlation between mTWA max and IVSth, between mTWA 5:00 and IVSth, LVPWth, as well as between mTWA 100 and LVPWth. The HCM patients did not demonstrate correlation between mTWA and the thickness of left ventricular wall. The patients with non-obstructive HCM (n=15) demonstrated significantly higher mTWA 100 in comparison to the patients with obstructive HCM (n=5). The presence of higher SCD risk factors in the HCM patients (n=6) did not influenced mTWA figures. The mTWA figures in the HHD and HCM patients differed insignificantly, with the only exception of higher mTWA 5:00 in the HHD in comparison to the HCM group.mTWA figures correlate with the degree of left ventricular hypertrophy, however the revealed correlations are weak. The causes of lower MTWA 100 in patients with more intensive hypertrophy (reverse correlation) as well as in patients with obstructive HCM in comparison with non-obstructive HCM call for additional studies."} +{"text": "Bordetella pertussis (DTwP). In contrast, similar studies suggest that many African females and males may have their lives saved each year by the nonspecific immunological benefits of Bacillus Calmette-Guerin (BCG) vaccination. From an immunological point of view, we hypothesise that the adverse effects of DTwP vaccine may occur because of the Th2-polarising effect of the aluminium phosphate adjuvant in the vaccine and because intramuscular administration of the vaccine may cause chronic inflammation at the site of injection. However, the Th1-polarising effect of BCG is likely to be beneficial. Sexual dimorphism affecting immune functions and vitamin A supplementation may influence both the deleterious and beneficial nonspecific effects of immunisation.A number of mainly observational studies suggest that many African females below the age of one year die each year from the nonspecific effects of vaccination with diphtheria-tetanus toxoids and killed (whole-cell) The paper discusses the immunology behind the reported nonspecific effects of DTwP and BCG vaccination: increased childhood mortality rates after DTwP and decreased mortality rates after BCG vaccination given during the course of the WHO recommended vaccine programs implemented in Guinea-Bissau and other low-income countries , 2.

The contribution of hereditary variants in the genes of transient receptor potential channels to neuropathic pain is unknown. We investigated the frequency of transient receptor potential ankyrin 1, transient receptor potential melastin 8 and transient receptor potential vanilloid 1 single nucleotide polymorphisms and their impact on somatosensory abnormalities in neuropathic pain patients. Within the German Research Network on Neuropathic Pain (Deutscher Forscbungsverbund Neuropathischer Schmerz) 371 neuropathic pain patients were phenotypically characterized using standardized quantitative sensory testing. Pyrosequencing was employed to determine a total of eleven single nucleotide polymorphisms in transient receptor potential channel genes of the neuropathic pain patients and a cohort of 253 German healthy volunteers. Associations of quantitative sensory testing parameters and single nucleotide polymorphisms between and within groups and subgroups, based on sensory phenotypes, were analyzed. Single nucleotide polymorphisms frequencies did not differ between both the cohorts. However, in neuropathic pain patients transient receptor potential ankyrin 1 710G>A was associated with the presence of paradoxical heat sensation (p\u200a=\u200a0.03), and transient receptor potential vanilloid 1 1911A>G with cold hypoalgesia (p\u200a=\u200a0.0035). Two main subgroups characterized by preserved (1) and impaired (2) sensory function were identified. In subgroup 1 transient receptor potential vanilloid 1 1911A>G led to significantly less heat hyperalgesia, pinprick hyperalgesia and mechanical hypaesthesia and transient receptor potential vanilloid 1 1103C>G to cold hypaesthesia (p\u200a=\u200a0.002), but there was absence of associations in subgroup 2. In this study we found no evidence that genetic variants of transient receptor potential channels are involved in the expression of neuropathic pain, but transient receptor potential channel polymorphisms contributed significantly to the somatosensory abnormalities of neuropathic pain patients. Neuropathic pain arises after lesions or diseases of the somatosensory nervous system and involves multiple somatosensory phenomena. In addition to spontaneous pain, these include negative and positive symptoms and signs such as hypaesthesia, hypoalgesia, thermal and mechanical hyperalgesia and allodynia The understanding of the molecular basis of neuropathic pain has been expanded by the cloning and characterization of the transient receptor potential (TRP) family of voltage-gated ion channels. Among these the TRP vanilloid 1 (TRPV1), TRP melastin 8 (TRPM8) and TRP ankyrin 1 (TRPA1) subfamilies have been found to play important roles in transduction and sensitisation in primary afferent somatosensory neurons Beside these physiological functions, TRPs are thought to play an important role in the generation of neuropathic pain, as demonstrated by in vitro and in vivo animal studies and neurophysiological and psychophysical studies in human experimental pain models and pain patients However, the contribution of a genetic variability in TRP channels on pain perception and pain generation in neuropathic pain patients is unknown. In this study we describe the results of an association analysis of polymorphisms in TRPV1, TRPM8 and TRPA1 genes with somatosensory signs of neuropathic pain patients. The aims were (1) to determine the frequencies of TRP variants in a large group of neuropathic pain patients of different aetiology and a cohort of healthy volunteers and (2) to determine the relationship of TRP gene variants and somatosensory function in neuropathic pain patients. Within this study we could demonstrate significant associations between the somatosensory function and TRP gene variants in neuropathic pain patients but no differences in the TRP frequencies compared with healthy volunteers.All subjects gave their written informed consent and the study was approved by the ethics committee of the Medical Faculty of the Christian-Albrechts-University Kiel and subsequently the Ethic Committees of the other participating DFNS centers and performed according to the Declaration of Helsinki.www.neuro.med.tu-muenchen.de/dfns/) were included in the study .

The final concentration of gDNA was determined spectrophotometrically. Two SNPs in TRPV1, six in TRPM8 and three in TRPA1 genes were identified by literature review in the context of neuropathic pain and selected for detailed association analysis . Except Before statistical analysis the QST values that did not show normal distribution were transformed logarithmically In order to identify major subpopulations of patients who are characterized by a typical combination of signs, a cluster analysis was performed in those patients only from whom complete QST results were available and for bi-allelic polymorphisms each subtest and genotype were calculated using analysis of variance (ANOVA). For dominant and recessive models the t-test was used, if applicable. To correct for multiple testing each test was performed using 100,000 permutations.The frequency distribution of all polymorphisms investigated was in Hardy-Weinberg equilibrium. Moreover, after correcting for multiple comparisons, the frequency of all SNPs did not differ significantly between neuropathic pain patients, healthy controls and data from the HapMap project .First, within the group of patients who suffered from paradoxical heat sensation (PHS) heterozygous and homozygous carriers of the TRPA1 710G>A variant were significantly under-represented as compared to neuropathic pain patients without PHS . Second,Hierarchical cluster analysis detected two main clusters . ClusterZ-scores of all QST tests were stratified to all TRP variants investigated in the entire sample and in both clusters. After correcting for multiple comparisons, two TRPV1 polymorphisms, 1911A>G and 1103C>G, were identified that had a significant relationship with the somatosensory function in cluster 1 .The TRPV1 1911A>G polymorphism was significantly associated with altered heat pain thresholds (HPT). Neuropathic pain patients being heterozygote or with wild type TRPV1 1911G genotype (AA or AG) tended to show heat hyperalgesia whereas TRPV1 1911G homozygotes exhibited significantly higher, i.e. normal heat pain thresholds . Homozygous variant carriers (GG) exhibited cold hypaesthesia compared with heterozygous or wild type carriers Click here for additional data file."} +{"text": "The intestine and the intestinal immune system have evolved through a symbiotic homeostasis under which a highly diverse microbial flora is maintained in the gastrointestinal tract while pathogenic bacteria are recognized and eliminated. Disruption of the balance between the immune system and the gut microbiota results in the development of multiple pathologies in humans. Inflammatory bowel diseases (IBD) have been associated with alterations in the composition of intestinal flora but whether these changes are causal or result of inflammation is still under dispute. Various chemical and genetic models of IBD have been developed and utilized to elucidate the complex relationship between intestinal epithelium, immune system and the gut microbiota. In this review we describe some of the most commonly used mouse models of colitis and Crohn's disease (CD) and summarize the current knowledge of how changes in microbiota composition may affect intestinal disease pathogenesis. The pursuit of gut-microbiota interactions will no doubt continue to provide invaluable insight into the complex biology of IBD.

Mucosal macrophages may prime the local inflammatory response through both phagocytosis of DSS and activation by bacteria products. The contribution of macrophage polarization phenotype to the development of CAC has been described using this model including the demonstration that Akt2 deficient mice are partly protected from DSS-induced colitis because of a macrophage phenotype shift from M1 to M2 in the colonic mucosa . DSS administered to the drinking water in repeated cycles triggers a state of chronic intestinal inflammation by binding to medium-chain-length fatty acids present in the mouse colon, inducing disruption of colonic epithelial barrier by cytochrome P450 . DMH is metabolized in liver and its derivatives induce the production of diazonium by gut epithelial cells. The aforementioned metabolite exerts mutagenic effects through oxidative stress and methylation events initiates acute T cell-mediated, IL-12 driven intestinal inflammation and develops numerous adenomas.

Recipient mice repopulated with CD4+CD45RBLo T cells or total CD4+ T lymphocytes do not develop colitis, despite their ability to colonize the host gut. This phenomenon is attributed to the presence of CD25+FoxP3+ regulatory T cells within the CD4+CD45RBLo population conditions results in spontaneous colitis which is transmissible to wild-type animals (which express T-bet) upon cross-fostering or co-housing , which harbors 8 genes and 5 micro RNAs and confers protection against H. hepaticus-induced chronic colitis and inflammation-driven colon cancer activity. Resident Treg produce IL-10 which inhibits Th1 cells and monocyte effector functions associated with inflammation.

Diagnostic guidelines for HLH and sJIA-associated MAS were applied to all MAS and control patients. Because no patient had NK-cell activity and soluble CD25 determination available and bone marrow aspirate was performed in only a few patients, these 3 criteria were excluded from HLH guidelines. HLH criteria were, therefore, met when at least 4 of the 5 remaining variables were present. sJIA-associated MAS criteria were met when at least 2 laboratory criteria or at least 1 laboratory criterion and 1 clinical criterion were present. Sensitivity and specificity of guidelines in discriminating patients with MAS from control patients were assessed.The table shows the comparison of sensitivity and specificity of diagnostic guidelines.The diagnostic guidelines for sJIA-associated MAS revealed strong sensitivity and specificity, whereas HLH guidelines were highly specific, but lacked sensitivity.

For this reason the recognition of pain and its severity is extremely important. Several pain scores and protocols are in use. We aimed to elucidate current practice of pain measurements and treatment in Dutch ICUs.In March 2011, a questionnaire was sent to all Dutch adult ICUs irrespective of the number of ICU beds with active follow-up by telephone calls to optimize the participation rate.A total of 84 ICUs (84/107) returned the survey, representing a response rate of 87%. Most ICUs are community teaching hospitals and nonteaching hospitals (85%) in comparison to academic hospitals (15%). Most ICUs (94%) use a standardized pain score in the group of patients who are capable of verbal communication: the Visual Analogue Scale (57%), Numerical Rating Scale (48%) and Faces Pain Scale (5%) being the most frequently used scores. In the group of patients who are unable to communicate, ICUs less frequently use pain scores (19%), with the Critical-Care Pain Observation Tool (6%) and Behaviour Pain Scale (5%) being used most frequently. Measurement of pain was considered most important for patients with burn wounds (67%), trauma patients (64%), postoperative patients (57%) and those who receive end-of-life care (64%). Barriers to use pain measurements included the patient's inability to communicate (82%), interference with pain assessment due to sedation (79%), hemodynamic instability (64%), insufficient dosages of analgesics (60%) and the unavailability of a standard pain scoring system (51%). In addition, guidelines for management of sedation and analgesics from the Netherlands Association for Intensive Care (NVIC) had been read by only 20% of the respondents. Factors that were mentioned to be useful in contributing to an improvement in pain assessment and effective pain control included adequate analgesic dosage (87%), utilization of protocols and directives (86%), enthusiastic and motivated personnel (81%) and the utilization of standardized pain measurement tools.Most Dutch ICUs measure pain frequently (94%) in patients who are able to communicate. However, in the group of patients who cannot communicate only 19% of the Dutch ICUs use a standardized pain score.

While our ability to identify abrupt regime shifts in natural ecosystems has improved, detection of potential early-warning signals previous to such shifts is still very limited. Using real monitoring data of a key ecosystem component, we here apply multiple early-warning indicators in order to assess their ability to forewarn a major ecosystem regime shift in the Central Baltic Sea. We show that some indicators and methods can result in clear early-warning signals, while other methods may have limited utility in ecosystem-based management as they show no or weak potential for early-warning. We therefore propose a multiple method approach for early detection of ecosystem regime shifts in monitoring data that may be useful in informing timely management actions in the face of ecosystem change. Transitions between alternative states, i.e., regime shifts, have been shown to occur across an array of complex systems Several early-warning indicators have been proposed to describe the temporal dynamics of complex systems close to a critical transition Pseudocalanus acuspes and Acartia spp., two key indicator species significantly contributing to the reorganization of the Baltic Sea ecosystem and sprat (Sprattus sprattus) Pseudocalanus acuspes and Acartia spp. serve as suitable indicators for the ecosystem regime shift in the Central Baltic Sea.

We used data representing spring as this is the main reproductive season of the copepods We used Pseudocalanus acuspes and Acartia spp. within a 10, 15 and 20-year sliding window, following the approach by Dakos et al.

Although not specifically designed for early detection of regime shifts, the idea of using trend analysis as an early-warning signal lies in the possibility of detecting a slight increase in the rate of change (either in an upward or downward trend) in advance of a critical transition in an ecological time series. The approach is based on fitting non-linear Generalized Additive Models (GAM) The third approach was not primarily designed for early detection either, but rather for the identification and detection of regime shift. It is based on the evaluation of statistical time series models including structural breaks and combines several statistical indicators into a so-called \u201cshiftogram\u201d per se but to assess how under the constraints of real ecological time series similar to ours, different approaches may or may not work, and which assumptions and drawbacks may pose the greatest challenges in terms of early-warning detection and applicability to management.The full set of early-warning methods were assessed in terms of (i) the potential for detecting early-warnings signals in the selected indicator time series, (ii) how far in advance early-warning signals could potentially be detected, (iii) associated methodological assumptions and drawbacks influencing early-detection and (iv) applicability to real ecosystem management in terms of data requirements. While the trend analysis and shiftogram approach may quantitatively evaluate the first two criteria , no predefined reference levels exist to objectively assess the performance of our ecological indicators of critical slowing down, nor the possibility to theoretically crash test the methods against a simulated (modeled) spatio-temporal data set Pseudocalanus acuspes strongly increased two years before the regime shift in 1988 one year ahead of the regime shift correlation showed p-values exceeding their upper confidence intervals one year in advance of the regime shift for both species .

Human sexuality is inherently related to some of the social and public health problems in India. These problems may involve contraceptive use, child abuse, sex education, legal issues of homosexuality and AIDS. These health problems have a significant impact on existing health infrastructure and budget. These problems also need to look within the context of poverty, stressful living situations, diverse cultural belief systems, quackery, ignorance and inadequate health services. However, there is little recognition of how these health problems are related to human sexuality and their dysfunctions. There is a need to understand how sexual attitudes, beliefs, and values act and influence these problems. Our cultural perspective can also shape the experience and understanding of these disorders. There isIn this review, our aim is to present sexual dysfunction from the Indian perspective. Available data, based clinical studies from India, are reviewed and important findings highlighted. Our presentation is limited to sexual dysfunction only and paraphilias will be not discussed.et al.

This MRI technique provides quantitative data on water molecular motion, as a marker of tissue structure. Materials & Method \u2013 Seventeen untreated migraine without aura (MO) patients underwent MRI scan (3-Tesla Siemens Gyroscan) during (n=7) and between attacks (n=10) and were compared to a group of 14 healthy volunteers (HV). We examined fractional anisotropy (FA) and mean diffusivity (MD) in the thalamus.Between attacks MO patients had a significantly higher FA and lower MD values in the bilateral thalami when compared to HV (p<0.05). During attacks, all MRI quantitative measurements in migraineurs were similar to those found in HV. In MO patients, FA of the right thalamus was positively correlated with the number of days since the last migraine attack .The higher thalamic FA values noted between attacks in MO patients may be related to a decrease in regional branching and crossing of fibers, which normalizes during an attack. Whether these changes could be considered as the anatomical counterpart of the cyclic functional fluctuations previously observed with the neurophysiology in migraine remains to be determined."} +{"text": "Sheep chromosome 3 (Oar3) has the largest number of QTLs reported to be significantly associated with resistance to gastro-intestinal nematodes. This study aimed to identify single nucleotide polymorphisms (SNPs) within candidate genes located in sheep chromosome 3 as well as genes involved in major immune pathways. A total of 41 SNPs were identified across 38 candidate genes in a panel of unrelated sheep and genotyped in 713 animals belonging to 22 breeds across Asia, Europe and South America. The variations and evolution of immune pathway genes were assessed in sheep populations across these macro-environmental regions that significantly differ in the diversity and load of pathogens. The mean minor allele frequency (MAF) did not vary between Asian and European sheep reflecting the absence of ascertainment bias. Phylogenetic analysis revealed two major clusters with most of South Asian, South East Asian and South West Asian breeds clustering together while European and South American sheep breeds clustered together distinctly. Analysis of molecular variance revealed strong phylogeographic structure at loci located in immune pathway genes, unlike microsatellite and genome wide SNP markers. To understand the influence of natural selection processes, SNP loci located in chromosome 3 were utilized to reconstruct haplotypes, the diversity of which showed significant deviations from selective neutrality. Reduced Median network of reconstructed haplotypes showed balancing selection in force at these loci. Preliminary association of SNP genotypes with phenotypes recorded 42 days post challenge revealed significant differences (P<0.05) in fecal egg count, body weight change and packed cell volume at two, four and six SNP loci respectively. In conclusion, the present study reports strong phylogeographic structure and balancing selection operating at SNP loci located within immune pathway genes. Further, SNP loci identified in the study were found to have potential for future large scale association studies in naturally exposed sheep populations. Haemonchus contortus, Teledorsagia circumcincta, Trichostrongyles, Nematodirus sp. impose severe constraints on sheep and goat production especially those reared by marginal farmers under low external input system. These parasites incur heavy losses to farmers in terms of body weight loss, direct cost of anthelminthic drugs, loss due to mortality, etc. For example, annual treatment cost for Haemonchus contortus alone had been estimated to be 26 million USD in Kenya, 46 million USD in South Africa and 103 million USD in India Haemonchus contortus, Trichostrongylus colubriformis, Teledorsagia circumcincta and various Nematodirus species. Considerable variation has been reported among sheep breeds on their ability to resist gastro-intestinal nematodes (GIN). For example, indigenous sheep breeds like Red Maasai 2\u200a=\u200a0.149, Avikalin sheep 2\u200a=\u200a0.41, Armidale sheep Assessment of livestock health conditions in developing countries for identification of priority diseases to be targeted for control, revealed helminth infections as one of the most important problems in sheep and goat Exploration of genetic variation either within specific regions of genome or more specifically in candidate genes involved in innate and adaptive immune pathways may help to identify a set of DNA markers significantly associated with parasite resistance characteristics. The former approach in terms of quantitative trait locus (QTL) analysis is a powerful method to understand genotype-phenotype relationship. Several QTL studies on parasite resistance characteristics have been reported in sheep. A quick evaluation of Animal QTL database Haemonchus contortus parasite).One of the important objectives of QTL studies is to identify underlying causative gene polymorphisms associated with the trait. Different QTLs reported in chromosome 3 for parasite resistance characteristics were found to be distributed all over the chromosome with varying overlapping regions. Hence, different candidate genes within chromosome 3 along with genes involved in immune related KEGG pathways (KEGG-Kyoto Encyclopedia of Genes and Genomes) could be important targets for establishing underlying causative variations. It is expected that the potential causative polymorphisms within candidate genes are members of the same overarching KEGG pathway that lead to the phenotypic expression on parasite resistance characteristics in each population. Further, the extent of genetic diversity and population sub-structure at such polymorphic loci are critical for such a genotype-phenotype association study. Population stratification has been demonstrated to result in false positive associations in various species including humans Haemonchus contortus and blood samples were collected from jugular vein under the supervision of qualified veterinarians for extraction of DNA and assessment of blood parameters. 42 days post challenge, animals were dewormed to clear parasites from the gut after the experiment. The experimental challenge in both locations did not involve animals from any endangered or protected species/breeds. Blood sample collection for DNA extraction and genotyping from remaining breeds were performed by local veterinarians in respective countries following good animal practice.All procedures for artificial challenge experiment at different locations in Argentina and Indonesia were approved respectively by the Institutional Committee for Care and Use of Experimental Animals of the National Institute of Agricultural Technology (CICUAE-INTA), Argentina (protocol number 35/2010) and Institutional Research Animal Facility, Bogor Agricultural University, Indonesia following the guidelines described in their institutional manuals. Experimental animals were challenged with infective L3 larvae of in vitro conditions. All animals were maintained together during the entire trial in dry lot or under conditions of minimum additional parasite challenge. Body weight (BW), fecal egg count (FEC) and packed cell volume (PCV) were recorded at 0, 28, 35 and 42 days after artificial infection. 136 animals from Corriedale (66), Pampinta (34), Indonesian Fat Tail (17) and Indonesian Thin Tail breeds of sheep (19) were utilized for artificial challenge at experimental stations located in Argentina and Indonesia respectively.A total of 713 unrelated sheep from 22 different breeds/populations were utilized for diversity analysis in the present study. The sheep breeds/populations were distributed in three macro-environmental geographical locations including Asia (tropics), Europe (temperate) and South America (tropics) with the assumption that level of parasite load and infections vary significantly across these regions http://www.mbio. ncsu.edu/bioedit/bioedit.html). 44 novel SNPs were identified within the candidate genes under study for which competitive allele specific PCR (KASPar) assay based on FRET chemistry were developed for genotyping . Briefly, two forward primers one specific to each allele were designed with the respective proprietary tail sequence complementing the FAM or HEX fluorescence reporting system. A common reverse primer was designed for each genotyping assay. Thermal cycling parameters and recycling conditions were followed as per manufacturer's recommendations and are available on request. Endpoint allele discrimination module incorporated within the BioRad CFX96 was utilized for calling the genotypes based on fluorescent intensity recorded for each of the two alleles. The emission data of all the samples in the plate were plotted in X and Y axis respectively for each allele and the genotypes were called based on distinct clustering. Quality of allele calling was confirmed by comparing the genotypes derived from KASPar assay with the available sequence data on individuals from the panel of unrelated animals. 38 out of 44 assays passed quality control and were subsequently utilized for genotyping large number of animals. Additionally, ten toll like receptor (TLR) genes were selected for in silico mining of SNP variations from sequences available at NCBI-GenBank database. A total of 14 non-synonymous SNPs within coding DNA regions of TLR genes were identified for development of genotyping assays using SPSS version 13.0. The first three principal components were used to draw the scattergram so as to understand underlying genetic structure and relationship of different breeds in three dimensional geometric space. The extent of population sub-structure was further explored using STRUCTURE with the assumption of different clusters, K\u200a=\u200a1\u201315, 20, 25 and 30. Five replicate runs were performed for each K under admixture model without a priori population information. The number of burn in periods and MCMC repeats used for all the runs were 50000 and 100000 respectively. To identify the optimal \u2018K\u2019, the second order rate of change of L(K) with respect to \u2018K\u2019 was calculated by following the procedure reported elsewhere Basic diversity indices like allele frequency, genotype frequency, expected heterozygosity and test for Hardy Weinberg equilibrium were calculated using PEAS www.stat.washington.edu/stephens) ST values using ARLEQUIN version 3.1 Thirteen SNP loci within candidate genes involved in different immune related KEGG pathways and located in chromosome 3 were used to reconstruct haplotypes from unphased genotypic data. Reconstruction of haplotypes and estimation of haplotype frequencies were performed using PHASE for Windows, version 2.1 , body weight change (BWC) and packed cell volume change (PCVC) measured 42 days post infective L3 larvae challenge. The data on FEC were subjected to log transformation before applying the program of least squares, LSMLMW A total of 243 sequences were generated by targeted re-sequencing of selected candidate genes to 0.315 (Hamdani) while the mean expected heterozyosity varied from 0.237 (Pampinta) to 0.315 (Indonesian Thin Tail). Among different geographical regions, mean observed heterozygosity was highest in South West Asian sheep populations (0.309) followed by European populations [0.296] while South East Asian populations had the least mean observed heterozygosity (0.270). This is consistent with the fact that the diversity remains higher around the centre of domestication while decreasing with increasing geographic distance ST to 0.469 (Pampinta/Mouflon). 21.3% of total genetic variation was found to be due to between breed differences while 77.3% was due to within breed differences. The values are much higher than that reported for European sheep (13.1%) ST values observed could be understood from the fact that the samples were derived from wide geographic locations in the present study . Further, phylogenetic analysis of pair-wise allele sharing distance revealed two major clusters with most of South Asian, South East Asian and South West Asian breeds clustering together while the European and South American sheep breeds clustered together separately were plotted on a three dimensional scattergram to evaluate the genetic structure of sheep breeds on 136 animals was used for least squares analysis under a complete fixed effect model. The effect of location of experimental stations was not found to have significant influence on fecal egg count and packed cell volume while significant effect was observed with respect to body weight change (P<0.01). Although the locations are wide apart geographically, uniform protocol was followed across different experimental stations in terms of age of lambs selected for experiment, deworming and data recording schedule, however some differences did exist in terms of quality of pasture available for grazing, etc. Higher observed body weight change in animals challenged at Aguil Experimental Station (AES), Argentina was due to better growth performance of Pampinta lambs. Higher body weight achieved by Pampinta lambs were due to their genetic differences in growth rate (average pre-weaning weight gain of 295 g/day) and weight gain (average weaning weight of 33.4 kg) as compared to other breeds like Corriedale (218 g/day and 24.6 kg) To evaluate the potential utility of the SNP loci for future association study on a large number of samples, a pilot analysis was performed with the phenotypes generated in four breeds after artificial challenge with infective L3 larvae of In conclusion, the present study reports strong phylogeographic structure in sheep across Asia, Europe and South America and balancing selection operating at SNP loci located within immune pathway genes. Although the present association analysis is preliminary in nature, the SNP loci on chromosome 3 and those within immune pathway genes indicated their potential for future large scale association studies in naturally exposed populations.Figure S1http://www.animalgenome.org/cgi-bin/QTLdb/index).(a\u2013c) QTLs related to gastro-intestinal nematode resistance in sheep (d) Chromosome-wise distribution of QTLs related to parasite resistance traits in sheep and number of SNP loci investigated in the present study (e) Quantitative trait loci (QTL) map of chromosome 3 related to parasite resistance traits in sheep Click here for additional data file.Figure S2Distribution of allele sharing distance (IBS) between pairs of individuals.

The level of cytosine methylation of CpG-rich (5meC) regions of the genome is a major epigenetic regulator and active global demethylation of 5meC throughout the genome is reported to occur within the first cell-cycle following fertilization. An enzyme or mechanism capable of catalysing such rapid global demethylation has not been identified. The mouse is a widely used model for studying developmental epigenetics. We have reassessed the evidence for this phenomenon of genome-wide demethylation following fertilisation in the mouse. We found when using conventional methods of immunolocalization that 5meC showed a progressive acid-resistant antigenic masking during zygotic maturation which gave the appearance of demethylation. Changing the unmasking strategy by also performing tryptic digestion revealed a persistence of a methylated state. Analysis of methyl binding domain 1 protein (MBD1) binding confirmed that the genome remained methylated following fertilisation. The maintenance of this methylated state over the first several cell-cycles required the actions of DNA methyltransferase activity. The study shows that any 5meC remodelling that occurs during early development is not explained by a global active loss of 5meC staining during the cleavage stage of development and global loss of methylation following fertilization is not a major component of epigenetic reprogramming in the mouse zygote. The mechanism that is currently considered to best describe 5meC reprogramming should result in an almost complete loss of methylation (<1%) by the time the embryo reaches the blastocyst stage. Analysis of around 1000 CpG islands (CGIs) within ovulated eggs shows that 15% are methylated de novo methylation occurs later, upon epiblast formation (D6.5)The dominant paradigm describing the processes of epigenetic reprogramming in the embryo holds that global active demethylation of 5meC occurs within the first cell-cycle. This demethylation acts preferentially on DNA inherited from the male while passive demethylation of the maternally derived genome occurs over subsequent mitoses Reports of an active process of global 5meC demethylation of the zygotic genome within hours of fertilisation in some species . This re-analysis did not find evidence for extensive active loss of methylation in zygotes or progressive loss due to an absence of maintenance methylation across the first several rounds of cell division. Rather, it was found that the reported loss of methylation immediately after fertilisation was accounted for by changes in the conformation or structure of chromatin that resulted in antigenic masking of 5meC.Mouse zygotes, 2-cell, 4-cell and 8-cell embryos were collected directly from the female reproductive tract from B6CBF1 strain female mice . The embryos were fixed and immunostained with anti-5meC. Zygotes were collected at various times after mating and staged according to the maturation of their pronuclei , is an independent measure of the global levels of CpG methylation. Western blot analysis showed two dominant molecular weight forms of MBD1 present in oocytes and the early stages of development . ImmunolBrief acid-treatment of cells has been the most widely used method of 5meC antigen retrieval reported. Altering the duration and concentration of HCl treatment did not change the pattern of 5meC staining in PN5 zygotes (not shown) showing that the difference between anti-5meC and anti-MBD1 staining was not due to increased acid-sensitive masking of 5meC. To determine whether other forms of masking may have occurred, fixed and acid-treated zygotes were subjected to extensive tryptic digestion. This caused a loss of MBD1 staining from nuclei 1\u20137 and aTo further assess this antigenic masking, condensing chromosomes of the zygote and 2-cell embryo were triple stained for DNA (blue), 5meC (green) and MBD1 (red). Acid-treated chromosomes from the zygote had some segments of undecorated DNA and large segments decorated by MBD1, but were largely devoid of staining by anti-5meC 1. By conIt is reported that further passive demethylation of the embryonic genome occurs during the cell-cycles following fertilisation due to limited maintenance methylation of the newly synthesized DNA Asymmetric anti-5meC staining of the male and female pronucleus after acid-pretreatment has been reported These analyses were all undertaken on embryos from hybrid (B6CBF1) mice. To assess whether the strain of mouse influenced the patterns of anti-5meC staining we also examined staining in an inbred (C57BL/6j) and an outbred (Swiss Quackenbush) strain embryos. Zygotes were collected directly from the reproductive tract fixed and stained for anti-5meC and PI. Hybrid embryos were collected and processed at the same time to act as controls. This analysis showed in acid-treated zygotes there was a similar progressive loss of anti-5meC staining of both PN4 and PN5 pronuclei in all three strains . Hybrid mice were used in most experiments.

Cardiac MRI (CMR) is now increasingly used for evaluation of these patients for defining pulmonary vein anatomy prior to PVI.We hypothesized that 2D and 3D non-contrast and contrast CMR is as effective as TEE in evaluating for LAA thrombus while providing simultaneous comprehensive non-invasive evaluation of the pulmonary vein anatomy within a single exam.Afib Pts underwent TEE and non-contrast and contrast CMR prior to undergoing an initial PVI procedure. CMR was performed on 1.5T GE scanner and two blinded CMR experts analyzed the images. The CMR images were analyzed under two categories: 1) the 2D non-contrast cine images showing LAA in 2 chamber and orthogonal views 2) 3D atrial contrast source-images acquired during pulmonary vein angiogram. CMR variables evaluated were the presence or absence of LAA thrombus, quality of images and the results were compared with the results of TEE in a blinded fashion.In 62% of pts (n=65) the CMR and TEE studies were performed on the same day, in 37 % of patients (n=39) the mean interval between the two studies was 7 days and in the remaining 6 patients the mean interval was 3+1months. All pts (n=110) were analyzed for the evaluation of LAA thrombus (avg time: 35 min). All (100%) of patients were in Afib and in all (100%) the images were of diagnostic quality (good correlation between the two CMR observers with only one grade difference when in disagreement). Thrombus was absent in 108 of 110 pts on TEE and CMR and present on 2 TEE and CMR images (100% concordance). In 9 cases the 2D CMR images were indeterminate where 3D contrast images were most helpful in the final rule out of LAA thrombus.CMR offers a comparable and equally specific alternative to TEE for the complete non-invasive evaluation of LAA thrombus in patients with Afib without the obligate need for sedation, radiation or nephrotoxicity. In one single examination a CMR exam can provide LAA anatomy, rule out thrombus and display the pulmonary veins in patients undergoing a PVI procedure."} +{"text": "Despite the availability of an effective vaccine, Hepatitis B virus (HBV) infection still remains a foremost health problem.

Vertical profiles of fine root attributes adjusted to one unit of basal area (BA) exhibited partial root system stratification when central beech is growing with spruce competitors. In this constellation, beech was able to raise its specific root length (SRL) and therefore soil exploration efficiency in the subsoil, while increasing root biomass partitioning into deeper soil layers. According to relative values of fine root attributes (rFRA), asymmetric below-ground competition was observed favoring beech over spruce, in particular when central beech trees are admixed with spruce competitors. We conclude that beech fine rooting is facilitated in the presence of spruce by lowering competitive pressure compared to intraspecific competition whereas the competitive pressure for spruce is increased by beech admixture. Our findings underline the need of spatially differentiated approaches to assess interspecific competition below ground. Single-tree approaches and simulations of below-ground competition are required to focus rather on microsites populated by tree specimens as the basic spatial study area.Scientists are currently debating the effects of mixing tree species for the complementary resource acquisition in forest ecosystems. In four unmanaged old-growth spruce-beech forests in strict nature reserves in southern Sweden and northern Germany we assessed forest structure and fine rooting profiles and traits (\u22642 mm) by fine root sampling and the analysis of fine root morphology and biomass. These studies were conducted in selected tree groups with four different interspecific competition perspectives: (1) spruce as a central tree, (2) spruce as competitor, (3) beech as a central tree, and (4) beech as competitor. Mean values of life fine root attributes like biomass ( Fagus sylvatica L.) and Norway spruce [Picea abies (L.)

All sites have comparably low amounts of fine-textured soil and are riddled with boulders. Soil traits of all three sites are comparable with a moderate to thick accumulation of organic material 5\u201312 cm; the humus type is moder to raw humus or raw humus (Siggaboda) with a high C/N ratio. Fine soil material is dominated by silt (40\u201365%) and sand (18\u201352%); the clay proportion is relatively low (8\u201317%) and the texture can be classified as sandy silt or silty sand, respectively. The soil type is a Haplic Podzol BGR, with a hdbh), tree heights, and basal area (BA) .All three mixed stands are dominated by spruce with higher mean values of stem density, diameter at breast height (A) Table . The SweForest stand structures were recorded in a 1 ha square core plot (100 \u00d7 100 m) in the center of the semi-natural forest representing a typical section of the old-growth stand. We subdivided the plot using a 20 m-grid of 7 cm and larger in winter 2004 at Siggaboda and in spring 2005 at the other sites. For each tree, species, cardinal location coordinates of the stem using above mentioned equipment and dbh with a girth tape were recorded. Subsequently, a tagging system was used for temporarily (between 2004 and 2007) marking and numbering each measured tree.Within the entire 1 ha core plot, we assessed each tree with a A) spruce as the central tree, (B) spruce as competitors, (C) beech as the central tree, and (D) beech as competitors. This design was completed by monospecies groups with comparable intraspecific competitive status that was only used as a reference for analyses of mixed species representation .We studied fine root structure of mature trees focusing on tree groups with one central tree with its mostly four\u2013five competitors . Therefore, beech-spruce tree groups representing four different types of interspecific competitive situations were selected: until the solid bedrock layer was reached. The maximum mineral soil depth sampled varied from 20 to about 40 cm. Various studies revealed that the maximum of fine roots is found in the top soil layers and vitality . We applied morphological criteria for the identification of dead root material: dead root parts exhibits a dark discoloration of the central cylinder and a decreased flexibility of root segments . The reported measurements allowed the calculation of specific root length and specific root surface area (SRA) from the ratio of fine root length (FRL) and root biomass, and fine root surface area and rooting biomass, respectively.All recorded root fragments were then dried for 48 h at 40\u00b0C and weighed in order to measure living fine root biomass , and thus variable species abundance above-ground :The data was included in a relational database running on the open source database system PostgreSQL and analyzed with the software package Statistica 9 and SAS JMP 9 (SAS Institute Inc. 2010). Differences between mean root traits were assessed either by the Kolmogorov-Smirnov-two-sample test, or by the Kruskal-Wallis H test when more than two samples or groups were compared. We used the respective tree BA per hectare of either spruce or beech as a reference unit for the comparison of fine root attributes (FRA are the life fine root attributes in terms of FRB (g m\u22122), FRL (m m\u22122), and RAI (cm2 m\u22122) of a central tree (CT) or n competitors (COMP), respectively. BA (m2 ha\u22121) is the BA of either spruce or beech, and FRAad are fine root attributes adjusted to the same BA (1 m2 ha\u22121) of either one central tree or of n competitors .where CT) or competitor (COMP) constellations of spruce and beech were further assessed by calculating relative fine root attributes in mixed groups with either CT or COMP constellations to those of pure stand groups (Equation 3). This enables the assessment of under- (<1) or overrepresentation (>1) of beech and spruce below ground growing in different mixed stand constellations under interspecific competition.The fine root representation of either central tree attained higher adjusted fine root abundance along the vertical rooting profile than the competitors exhibited significantly higher fine root abundance in both the humus layer and deeper soil layers compared to beech competitors (COMP). This was not the case for spruce with a quite equal allocation of fine root proportion along the profile for both CT and COMP constellations. A spatial separation of the fine roots of spruce and beech was visible for the deeper soil horizons (10\u201340 cm) when growing with beech as the central tree and spruce as competitors resulting in high beech and low spruce fine root quantities. This partially vertical stratification was mainly due to high plasticity of beech fine rooting as a central tree. No stratification was visible in the organic layer and top soil where both species reached their maximum abundances.For both spruce and beech, central trees (SRL and specific fine root surface area (SRA) attained values for mixed beech (CT and COMP) of SRL 12.7 \u00b1 5.5 m g\u22121 and of SRA 367.3 \u00b1 125.9 cm2 g\u22121 compared to mixed spruce of SRL 6.6 \u00b1 3.8 m g\u22121 and of SRA 253.6 \u00b1 108.1 cm2 g-1 . However, total SRL and SRA differences between CT and COMP constellations within both species were not significant.Total means of specific SRL and SRA support the idea of higher plasticity of beech fine rooting . For spruce in contrast, we did not find such changes between central spruce trees (CT) and its competitors (COMP) rooting behavior. However, significant higher SRL and SRA values of CT constellations in the humus layer and the top soil points to higher competitive investments for rooting space sequestration in the upper soil horizons of single central spruce trees (CT), whereas single beech trees (CT) invested more in deeper soil horizons with less competitive abundance of spruce roots. Comparing beech and spruce as interspecific competitors (COMP), one can observe quite similar vertical rooting behavior , beside the above mentioned fact that the overall level of beech is much higher than that of spruce.The vertical profiles of g Figure . WhereasrFRA, cf. Equation 3) in mixed CT and COMP constellations and COMP constellations on interspecific tree species representation compared to the intraspecific one (Table rFRA). Two major findings were derived: (1) spruce is underrepresented in fine root abundance in mixed stands (mean rFRA < 1) whereas beech is overrepresented (mean rFRA > 1); (2) both beech overrepresentation and spruce underrepresentation address CT constellations with beech as the central tree (B). This indicates that beech rooting was favoured by an asymmetric interspecific competition of both species when several spruce competitors grew together with a single beech tree. But this was not the case for CT constellations with central spruce and beech competitors where we found a quite symmetric interspecific competition. Combining results from the existing mixtures (means of A + D) of central spruce (CT) and competing beech (COMP) or vice versa (means of B + C) one can assess fine root representation effects of the mixtures compared to either beech or spruce pure groups. It turned out that due to the low fine root representation of spruce no existing mixture reaches the high fine root representation of pure beech. However, both mixture constellations lead to higher fine root representation compared to the pure spruce plots.For the analyses of fine root representation of the mixed stand plots in Sweden is related to the remarkably low tree abundance above ground compared to the Swedish plots. The positive relationship between tree dimension (BA) and soil exploration (FRB) on microsite and tree level has been demonstrated by Bolte and Villanueva of central beech and competing spruce in deeper soil horizons and mixed beech (12.7 m g\u22121) lie within the lower part of the range for spruce and beech (d < 2 mm) of 4.5\u201326 and 5.7\u201331.5 m g\u22121, respectively, reported by the extensive meta-analyses of Ostonen et al. are similar to those reported for mixed spruce by Bolte and Villanueva of beech does not mean that resource exploitation is more efficient compared to spruce increased SRL in deeper soil layers. This indicates additional soil exploration activities at low carbon costs in soil depths from 20 cm downwards fitting well to the findings of changed root system partitioning favouring deeper soil horizons for increasing complementary resource exploitation and \u201cunderground niche separation\u201d adjusted to the same unit of above ground performance (1 m2 BA per hectare) with adjusted values for monospecies plots is in line with other studies reporting an over-proportional reduction of fine root abundance in beech mixtures with spruce surrounding a single beech tree (CT) have a low fine root representation possibly reflecting intensive above ground competition between central beech and spruce competitors leading to increased biomass partitioning toward aboveground tree compartments. Beech fine root representation on the other hand is favored by interspecific competition with spruce. The found morphological belowground plasticity (variation of rooting depth in CT constellation and of SRL/SRA) reflects the high crown plasticity (Dieler and Pretzsch, The relative fine root representation is a measure to compare mixed species abundance (SRL and with this soil exploration efficiency in the subsoils while increasing root biomass partitioning toward deeper soil layers. Moreover, asymmetric below-ground competition was observed favoring beech toward spruce in a mixed constellation with central beech. We conclude that beech fine rooting is facilitated in the presence of spruce by lowering competitive pressure compared to intraspecific competition whereas the competitive pressure for spruce is increased by beech admixture. This is most obvious when central beech trees are admixed with spruce competitors. Our findings underline the need of spatially differentiated approaches to assess interspecific competition below ground. Since tree competition is a process that affects tree at an individual scale, stand scale analyses should be complemented by single tree approaches, above and below ground. In line with the recent development of crown competition assessments and stand simulation methods (e.g., Pretzsch et al., The results of the presented study exhibited an only partially vertical root system stratification in the subsoil in the three spruce-beech old-growth stands and depended on specific mixture constellation: beech central tree with spruce competitors.

Despite significant advances in understanding structure and function of molecular chaperones, organizing molecular principles that control the relationship between conformational diversity and functional mechanisms of the Hsp90 activity lack a sufficient quantitative characterization. We combined molecular dynamics simulations, principal component analysis, the energy landscape model and structure-functional analysis of Hsp90 regulatory interactions to systematically investigate functional dynamics of the molecular chaperone. This approach has identified a network of conserved regions common to the Hsp90 chaperones that could play a universal role in coordinating functional dynamics, principal collective motions and allosteric signaling of Hsp90. We have found that these functional motifs may be utilized by the molecular chaperone machinery to act collectively as central regulators of Hsp90 dynamics and activity, including the inter-domain communications, control of ATP hydrolysis, and protein client binding. These findings have provided support to a long-standing assertion that allosteric regulation and catalysis may have emerged via common evolutionary routes. The interaction networks regulating functional motions of Hsp90 may be determined by the inherent structural architecture of the molecular chaperone. At the same time, the thermodynamics-based \u201cconformational selection\u201d of functional states is likely to be activated based on the nature of the binding partner. This mechanistic model of Hsp90 dynamics and function is consistent with the notion that allosteric networks orchestrating cooperative protein motions can be formed by evolutionary conserved and sparsely connected residue clusters. Hence, allosteric signaling through a small network of distantly connected residue clusters may be a rather general functional requirement encoded across molecular chaperones. The obtained insights may be useful in guiding discovery of allosteric Hsp90 inhibitors targeting protein interfaces with co-chaperones and protein binding clients. The molecular chaperone Hsp90 (90 kDa heat-shock protein) is required for managing conformational development, stability and function of proteins in the cellular environment E coli homologue, HtpG Structural and biochemical studies have established Hsp90 as an ATP-dependent system that operates as a homodimer in a functional cycle associated with the ATP binding and hydrolysis Modern biophysical approaches including X-ray crystallography, electron microscopy and small-angle X-ray scattering (SAXS) have provided a more detailed characterization of the Hsp90 conformational states during progression through the ATPase cycle Computational approaches have been instrumental in revealing the atomic details of the inter-domain communication pathways which may regulate the conformational equilibrium of the molecular chaperone. We have recently reported the first computational study of the Hsp90 allosteric binding with an atomic level analysis of the conformational motions and the inter-domain communication pathways in the full-length yeast Hsp90 dimer in the apo form and complexes with ATP and ADP Mechanistic and thermodynamic models of allosteric communication have become widely accepted and broadly applied to analyze mechanisms of allosteric regulation in proteins and biological networks Structure-functional studies of Hsp90 regulation have proposed a number of functional motifs that may contribute to the regulation of Hsp90 activity, including ATP hydrolysis and allosteric interactions. Nevertheless, molecular mechanisms that control the relationship between conformational diversity and biological functions of Hsp90 lack a detailed quantitative characterization. In this work, we integrated molecular dynamics (MD) simulations and modeling of the principal collective motions with the energy landscape models and structure-functional analyses of regulatory interactions to characterize functional dynamics of the Hsp90 molecular chaperones and formulate a unifying theoretical framework that may adequately describe and rationalize molecular principles of Hsp90 dynamics and function.We begin by providing a road-map through the manuscript and formulating main questions, computational experiments conducted and hypotheses tested. In the present work, we integrated all-atom MD simulations with modeling of principal correlated motions, the energy landscape analysis and structure-functional characterization of regulatory interactions to investigate functional dynamics and mechanisms of the Hsp90 molecular chaperones. The following specific objectives were pursued in this study: (a) to quantify molecular mechanisms by which functional dynamics and allosteric motions of Hsp90 may be connected with the probabilistic nature of the underlying energy landscape; (b) to identify and characterize functional hotspots shared by the Hsp90 chaperones that could coordinate functional dynamics and \u201cconformational selection\u201d of the functional states. We proposed that conformational dynamics and functional motions of Hsp90 may be described using the energy landscape models and principles of \u201cconformational selection\u201d (or \u201cpopulation-shift\u201d) between preexisting conformational ensembles In the first section, we discussed the results of MD simulations performed for all structural forms of Hsp90. A comparative analysis of the conformational ensembles highlighted fundamental aspects of Hsp90 dynamics that may be exploited by the chaperone to accommodate functional requirements during the ATPase cycle. In the second section we characterized functional dynamics and principal collective motions of the molecular chaperone. This analysis demonstrated that a central evolutionary conserved characteristic of Hsp90 dynamics is the presence of long-range inter-domain motions that enable allosteric signaling. We concluded that allosteric interactions may provide a mechanism for structural adaptation of Hsp90 by shifting the dynamic equilibrium between the ensembles of functional states. A switch-based conformational change is a hallmark of complex biomolecular systems that function via allosteric signaling and are often regulated by a relatively small number of functional hot spots , , The crystal structures of the full-length Hsp90 dimer from three different species revealed a similar domain architecture, yet significant differences in the global conformational flexibility and the relative domain orientation Figure 1Figure S1) that may serve as stabilizing \u201chandlers\u201d in assisting the central \u201cstrap\u201d of hydrophobic residues (residues 755\u2013765) to ensure structural integrity of the M-domain and CTD of MD trajectories.

This analysis identified the shapes of the low frequency modes and the protein regions subjected to correlated and/or anti-correlated motions along the selected low frequency modes.Sstructural mapping of the HtpG mobility projected along the low frequency modes revealed a heterogeneous and diffuse network of structurally stable regions distributed across all domains of the extended HtpG form , the catalytic loop in the M-domain (residues 332\u2013342) and the adjacent H10 helix (residues 343\u2013366) are among functional regions that become protected upon ATP binding The full-length mammalian Grp94 in complex with either ATP or ADP has a semi-open, V-shaped conformation of the dimer , , , The ATP-bound yeast Hsp90 is characterized by structurally constrained conformation, stabilized by a dense network of both intra-monomer and inter-monomer interactions , , , 8These findings are in accordance with insights by Wolynes and coworkers Within the energy landscape framework, long-range cooperativity of allosteric interactions during allosteric transitions may favor a combination of the population-shift and induced-fit mechanisms Allosteric signaling is often enabled by a relatively small number of evolutionary conserved and sparsely connected regulatory hotspots. In this section, we describe a computational approach to identify and characterize a network of conserved functional motifs responsible for regulation of Hsp90 dynamics. We propose that functional motifs coordinating functional dynamics and collective motions of the Hsp90 chaperone may serve as central regulators of Hsp90 activity. Structurally rigid and conformationally flexible residues may often occupy proximal positions to the hinge sites, since the regions of high and low structural stabilities could participate in binding sites We focus on the low-frequency functional motions represented by the normalized mean square fluctuation (NMSF) of the Hsp90 chaperone residues, along the two lowest frequency modes. These profiles can reflect salient features of the intrinsic protein dynamics , , According to this analysis, the NMSF profiles along the two slowest modes of HtpG motions confirmed the presence of anti-correlated motions between the NTD and CTD in the open apo-HtpG form , 10. TheInterestingly, this charged linker in Grp94 (residues 287\u2013327) was deleted in the protein construct and replaced by four glycine residues in the crystal structures In the framework of the energy landscape model, this inter-domain region may facilitate cooperative interactions and efficient allosteric communication networks in HtpG. The alterations in this region observed in Grp94 may introduce a degree of inter-domain frustration that would detrimentally affect allosteric interaction networks. These findings could rationalize several important biochemical experiments REILQD-342 in HtpG . When Hsp90 dimer forms an initial complex with two Cdc37 molecules Figure S2). According to our mechanistic model, the binding sites of these motifs may recognize the \u201cincoming\u201d co-chaperone molecules, and the Cdc37 dimer would then bind the two linker regions. The regulatory elements of these motifs may then \u201cpass\u201d the binding signal information via allosteric communication pathways and trigger switching of the thermodynamic equilibrium towards a more open and flexible ADP-bound state of Hsp90 suitable for recognition of protein kinase clients.Hence, allosterically regulated conformational equilibrium of Hsp90 and co-chaperone binding are closely associated and may be modulated via the stochastic nature of the underlying energy landscape. Based on our findings and agreement with structure-functional experiments , IV-539 containing a pivotal switch point Ile-538 in HtpG emerged as a central element of the CTD regulatory motif involved in coordinating the inter-domain communications. The evidence of an efficient molecular communication between NTD and CTD regions at the interface is of special importance given a rapidly growing interest in developing novel and specific Hsp90 inhibitors targeting allosteric C-terminal nucleotide binding site Hence, we identified universal functional motifs shared by the Hsp90 chaperones in different species that could play a universal role in coordinating functional dynamics and principal collective motions of Hsp90. These motifs may also serve as central functional regulators of Hsp90 activity, including control of ATP hydrolysis, the inter-domain communications and protein client binding. We observed that recognition sites may correspond to the conformationally mobile regions along slow modes of principal motions. Moreover, the recognition sites are often strategically positioned close to the regulatory anchor motifs containing catalytic and/or hinge residues. According to our results, functional coupling of structurally stable and conformationally mobile elements in the regulatory motifs is what may enable allosteric signaling and recognition of co-chaperones and protein clients. The central result of this study is that a small number of functional motifs may be utilized by the chaperone machinery to act collectively as central regulators of Hsp90 dynamics and activity, including the inter-domain communications, control of ATP hydrolysis, co-chaperone binding and protein client recognition. Mutations, drug targeting, and probing protein binding in these regions would allow furthering pinpointing specific residues responsible for various functions including protein binding.It becomes more apparent now that functional dynamics of Hsp90 is closely associated with the ability of the molecular chaperone to bind and control activity of numerous protein clients. During client binding, the Hsp90 chaperone can adopt equilibrium between structurally different states that is maintained even after substrate loading In this work, we identified and characterized evolutionary and functionally conserved elements of the Hsp90 chaperone that may serve as key regulators of collective motions and hubs of long-range communication networks. We propose that functional clusters corresponding to stable regions in principal collective motions define minimally frustrated anchor sites (\u201chot spots\u201d). These minimally frustrated residue clusters with optimized local interactions may be critical for regulation of allosteric signalling between distant protein regions. The proximal recognition sites (\u201csoft spots\u201d) may be functionally coupled to the anchoring regulatory residues and form networks of communicating interaction clusters. These \u201csoft spots\u201d may be formed by locally frustrated residues, whose interaction networks are energetically optimized and prone to dynamic modulation by mutations or protein client binding. Hence, allosteric signaling may involve a dynamic coupling between structurally rigid and plastic clusters of residues. A switch in state at a soft cluster upon protein client binding can shift the thermodynamic balance and activate a specific network of allosterically coupled residues. This model is consistent with the central role of regulatory nodes as \u201cdiscrete breathers\u201d or independent dynamic segments in allosteric signaling Overall, the proposed mechanistic picture of Hsp90 function is consistent with studies showing that allosteric networks orchestrating cooperative protein motions can be formed by evolutionary conserved and sparsely connected groups of residues, suggesting that rapid transmission of allosteric signals through a small network of distantly connected residue clusters may be a universal requirement encoded in the molecular chaperones and possibly other macromolecular assemblies. Our analysis has also confirmed that Hsp90 homologues sharing the same fold architecture may exhibit similar dynamical characteristics, including conservation of principal collective motions. The results support a mechanistic hypothesis according to which that the interaction networks regulating collective motions of the Hsp90 chaperone may be determined by the inherent structural architecture of the molecular chaperone. At the same time, the thermodynamics-based \u201cconformational selection\u201d of Hsp90 functional states is likely to be readily modulated by co-chaperones and protein binding partners.Targeting allosteric binding sites and interrupting protein client binding with Hsp90 can produce a broad-spectrum antitumor activity and a low risk of drug resistance due to a combinatorial blockade of multiple signaling pathways. While there has been a steady progress in structural studies of the Hsp90-NTD complexes with small molecules, much less is known about the molecular basis of allosteric Hsp90 binding with co-chaperones and protein clients. A second nucleotide-binding domain has been reported to exist in the C-terminus of Hsp90, and specific inhibitors to this domain are represented by novobiocin and the related coumarin antibiotics The results of our study could guide design of experiments for probing allosteric binding of celastrol by introducing mutations in the communicating residues from the regulatory and recognition motifs of Hsp90. Integration of computational and experimental approaches may thus facilitate experimentally-guided mapping of allosteric binding states and help to specify whether Hsp90 or its co-chaperone Cdc37 is the primary target for binding of celastrol. Recent evidence suggests that Hsp90 interacts and stabilizes a growing list of protein kinases, and Cdc37 serves as the key co-chaperone for a large portion of the yeast kinome +) and chloride (Cl\u2212) counter-ions were added to achieve charge neutrality in MD simulations at physiological concentration of 0.15 mol/L. All Na+ and Cl\u2212 ions were placed at least 8 \u00c5 away from any protein atoms and from each other. The system was subjected to initial minimization for 20,000 steps (40 ps) keeping protein backbone fixed which was followed by 20,000 steps (40 ps) of minimization without any constraints. Equilibration was done in steps by gradually increasing the system temperature in steps of 20 K starting from 10 K until 310 K and at each step 15000 steps (30 ps) equilibration was run keeping a restraint of 10 Kcal mol\u22121 \u00c5\u22122 on protein alpha carbons (C\u03b1). Thereafter the system was equilibrated for 150,000 steps (300 ps) at 310 K (NVT) and then for further 150,000 steps (300 ps) at 310 K using Langevin piston (NPT) to achieve uniform pressure. Finally the restrains were removed and the system was equilibrated for 500,000 steps (1 ns) to prepare the system for simulation. An NPT simulation was run on the equilibrated structure for 20 ns keeping the temp at 310 K and pressure at 1 bar using Langevin piston coupling algorithm. The integration time step of the simulations was set to 2.0 fs, the SHAKE algorithm was used to constrain the lengths of all chemical bonds involving hydrogen atoms at their equilibrium values and the water geometry was restrained rigid by using the SETTLE algorithm. Nonbonded van der Waals interactions were treated by using a switching function at 10 \u00c5 and reaching zero at a distance of 12 \u00c5. The particle-mesh Ewald algorithm (PME) as implied in NAMD was used to handle long range electrostatic forces.MD simulations of the Hsp90 structures (each of 20 ns duration) were performed for a closed ATP-bound conformation of yeast Hsp90 (PDB ID 2CG9) \u03b1 atoms) i and j was calculated for each of the 20 ns MD simulation trajectories: snapshots from trajectories were taken every 200 ps, overall translation and rotation were removed, and only C\u03b1 was kept for analysis.Protein flexibility was analyzed by combining the results of MD simulations with the principal component analysis of conformational ensembles To obtain collective motion coordinates that represent the overall dynamics of each trajectory, PCA was performed, in which the covariance matrix Figure S1Time-Dependent History of High Occupancy Salt Bridges.

Here we examine the hypothesis that these differences arise because of a link between the tonal characteristics of a culture's music and its speech. We tested this idea by comparing pitch intervals in the traditional music of three tone language cultures and three non-tone language cultures with pitch intervals between voiced speech segments. Changes in pitch direction occur more frequently and pitch intervals are larger in the music of tone compared to non-tone language cultures. More frequent changes in pitch direction and larger pitch intervals are also apparent in the speech of tone compared to non-tone language cultures. These observations suggest that the different tonal preferences apparent in music across cultures are closely related to the differences in the tonal characteristics of voiced speech. Tonal differences between traditional Eastern and Western music are readily heard. Explanations often refer to the use of different scales The use of pitch in speech varies greatly among languages. The most obvious example is the broad division of languages into \u201ctone\u201d and \u201cnon-tone\u201d groups Based on these differences, we asked how, if at all, differences in the use of pitch in the traditional music of tone and non-tone language speaking cultures compares with the use of pitch in speech. To address this question, we compiled databases of speech and music from several tone and non-tone language cultures. The analysis focused on two aspects of pitch dynamics: the frequency of changes in pitch direction , and the size of the pitch intervals used. These aspects were chosen because they differentiate tone and non-tone language speech and play a central role in the structure of musical melodies U\u200a=\u200a9843.5, P<0.001; U\u200a=\u200a2317, P<0.001; t\u200a=\u200a-11.4, P<0.001), whereas intervals equal to or larger than a major second occur more often . The only exception in this overall pattern is major thirds (400 cents), which are more frequent in the music of non-tone language cultures (7.7% vs. 2.3%). t\u200a=\u200a\u22125.6, P<0.001), whereas larger intervals occur more often . and three that use non-tone languages . The patterns apparent in music parallel those in speech. Thus the music of tone language cultures changes pitch direction more frequently and employs larger melodic intervals. Similarly, the speech of tone language cultures changes pitch direction more frequently and employs larger prosodic intervals. Presumably tone language speech exhibits these characteristics because the lexical meaning of each syllable in a tone language is tonally determined The only exception to this pattern is the use of major thirds. Despite the greater frequency of larger prosodic intervals (\u2265200 cents) in the speech of tone compared to non-tone languages, there are fewer melodic major thirds (400 cents) in the music of tone language cultures see . A possiIn sum, co-variation of tonal characteristics in the music and speech of the tone and non-tone language speaking cultures we examined indicates an intimate relationship between these two modes of social communication, providing a way of explaining at least some aesthetic preferences in biological terms.Monophonic folk melodies from tone and non-tone language speaking cultures, all of which could be either played on an instrument or sung, were obtained from scores and MIDI format files obtained principally from National University of Singapore and the Singapore National Library Board. The tone language database comprised 50 traditional Mandarin, 20 traditional Thai, and 20 traditional Vietnamese melodies. The non-tone language database comprised 50 traditional American, 20 traditional French, and 20 traditional German melodies.

Each speaker read 5 emotionally neutral monologues translated into the appropriate language . Prior tThe analysis of music focused on melodic slope reversals, and melodic interval size. Melodic slope reversals were defined as any change in the direction of the pitch contour of a melody. For each melody, the number of local minima and maxima was tabulated and divided by the total number of notes; this value was multiplied by 100 to give the incidence of melodic slope reversals per 100 notes. Melodic interval size was defined as the pitch difference (in cents) between adjacent notes see . The analysis of speech focused on two aspects of pitch dynamics analogous to those examined in music: prosodic slope reversals, and prosodic interval size.

Analysis of V(D)J recombination activity is typically performed using extrachromosomal recombination substrates that are recovered from transfected cells and selected using bacterial transformation. We have developed a two-colour fluorescence-based system that simplifies detection of both deletion and inversion joining events mediated by RAG proteins.This system employs two fluorescent reporter genes that differentially mark unrearranged substrates and those that have undergone RAG-mediated deletion or inversion events. The recombination products bear the hallmarks of true V(D)J recombination and activity can be detected using fluorescence microscopy or flow cytometry. Recombination events can be detected without the need for cytotoxic selection of recombination products and the system allows analysis of recombination activity using substrates integrated into the genome.This system will be useful in the analysis and exploitation of the V(D)J recombination machinery and suggests that similar approaches could be used to replace expression of one gene with another during lymphocyte development. The antigen receptor loci of B and T lymphocytes exhibit a unique mechanism of control amongst the genes of multicellular organisms. The production of functional immunoglobulin (Ig) and T cell receptor (TCR) genes is accomplished through a tightly regulated process of recombination.

Additionally, the functional divergence within the myogenic determination factors or differentiation factors was also under positive selection pressure. The positive selection sites were more frequently detected from MyoG and MyoD than Myf6 and Myf5, respectively. Amino acid residues under positive selection were identified mainly in their transcription activation domains and on the surface of protein three-dimensional structures. These data suggest that the functional gain and divergence of myogenic regulatory factors were driven by distinct positive selection of their transcription activation domains, whereas the function of the DNA binding domains was conserved in evolution. Our study evaluated the mechanism of functional divergence of the transcriptional regulation factors within a family, whereby the functions of their transcription activation domains diverged under positive selection during evolution.The functional divergence of transcriptional factors is critical in the evolution of transcriptional regulation.

In contrast, MyoG and Myf6 are myogenic differentiation factors that contribute to the differentiation of myoblasts and act downstream of Myf5 and MyoD, though Myf6 partly acts at both the determination and differentiation levels Myf5 and MyoD have redundant functions in myoblast determination and can compensate for the functional loss of each other, Myf5 plays a more critical role during the early determination of epaxial muscle, whereas MyoD is more critical for hypaxial muscle determination Myogenesis involves two major temporally ordered steps. First, myogenic progenitor cells (myoblasts) originate from mesenchymal precursor cells, and second, these cells then terminally differentiate into mature muscle fibers Myf5, MyoD, MyoG, and Myf6 genes were duplicated from a single invertebrate gene Caenorhabditis elegansAnthocidaris crassispinaDrosophila melanogasterCiona intestinalis, it gives rise two different transcripts of MRFs (MDFa and MDFb) as a result of alternative splicing. Moreover, in cephalochordates, the amphioxus have two MRF genes: BMD1 and BMD2MyoD in ascidians suggest that the regulation pattern of multiple MyoD genes has evolved under selective pressure before the MRF genes were duplicated into multiple copies Myf5 and MyoD genes were then duplicated from one of these two lineages, whereas MyoG and Myf6 were duplicated from the other lineage during vertebrate evolution. Therefore, the functional redundancy between Myf5 and MyoD as well as between MyoG and Myf6 might be due to their common genetic origin Genome duplication is believed to be a major genetic event that occurs during the evolution of a gene family from a single gene to multiple gene copies The mechanisms underlying the evolution of the MRF gene family during their duplication remain unclear. In particular, the evolutionary forces affecting the functional divergence of the four MRFs genes have not been fully elucidated. In this study, we investigated the mechanisms underlying the evolution of the four MRF genes with particular emphasis on the selective pressures imposed on the branches and sites of MRFs during vertebrate evolution. Our study provides several lines of evidence for the role of positive selection in the functional divergence of transcription factors.Myf5 and MyoD), but not in the myogenic differentiation factors (Myf6 and MyoG) .

The functional divergence between these factors was estimated using the DIVERGE 2.0 program Myf5/MyoD and MyoG/Myf6 branches, which was significantly greater than 0 (p<0.01). Thus, the functional divergence between Myf5/MyoD and MyoG/Myf6 was significant. Twenty-nine residues have a stringent threshold of a posterior ratio higher than eight. Most of these sites were located in the BASIC, MYF5 domains and C-terminus, which might be critical for the functional divergence between the myogenic determination factors (Myf5 and MyoD) and myogenic differentiation factors (Myf6 and MyoG) (Myf5/MyoD lineage (branch a in MyoG/Myf6 lineage (branch b in The myogenic determination factors (nd MyoG) .

In addition, two amino acid regions (SXXTSPXSNCSDGM and SSLDCLSXIVXRIT) might be critical in the functional gain of the myogenic determination role in Myf5 and MyoD and differentiation factors (Myf6 and MyoG) was driven by positive selection. Positive selection sites responsible for this divergent process were identified from the BASIC, MYF5 domains and C-terminus was also under positive selective pressure. The evolution processes of MyoD in all vertebrates are driven by positive selection on the BASIC and MYF5 domains also diverged under positive selection. The positive selection on the BASIC and C-terminus were identified in the bird MyoG lineage and the teleost MyoG lineage . The MRF sequences were aligned by the program MUSCLE or ClustalW, and all gaps were eliminated by manual edition and synonymous (dS) substitution rates were calculated by the Nei-Gojobrotri (Jues-Cantor) method as implemented in the MEGA5.0 program to measure the pairwise sequence distances of the three domains among different MRFs The CODEML program in the PAML4 Three-dimensional structures of the proteins were predicted using the worldwide web following the methods of a case study using the Phyre server Myf5/MyoD) and myogenic differentiation factors (MyoG/Myf6).

The aim of this study was to identify patients with Parkinson's disease who showed loss or decrease of nocturnal blood pressure fall (nondipper patients) as a marker of autonomic dysfunction. Presence or absence of orthostatic hypotension was considered to investigate whether alterations in circadian blood pressure pattern are associated with posture-related dysregulation of blood pressure. Methods. 40 patients with Parkinson's disease underwent 24-hour blood pressure monitoring. 21 patients were diagnosed with arterial hypertension and received anti-hypertensive drugs. Nondipper patients were defined as having nocturnal decrease of mean systolic and diastolic blood pressure less than 10%. Presence or absence of orthostatic hypotension was determined by Schellong's test. Results. We identified 35 nondipper patients (88%). Nondipping was detected in 20 patients with orthostatic hypotension (95%) and in 15 patients without orthostatic hypotension (79%). 18 patients with hypertensive and 22 patients with normal blood pressure values were detected. Conclusions. In conclusion 24-hour blood pressure monitoring showed a high prevalence of nondipping in 40 patients with Parkinson's disease with and without orthostatic hypotension independent of coexisting arterial hypertension and antihypertensive treatment. 24-hour blood pressure monitoring may be useful to identify non-dipping as a marker of autonomic dysfunction in patients with Parkinson's disease. Parkinson's disease is a multisystem degeneration . Beside Involvement of the autonomic nervous system (ANS) occurs in the early stages of the disease . Cardiovascular dysautonomia, especially orthostatic hypotension, is frequently reported in Parkinson's disease .Involvement of peripheral components of the ANS can be demonstrated by MIBG scintigraphy.MIBG scintigraphy shows reduced cardiac uptake of MIBG (meta-[123I]iodobenzylguanidine) representing loss of postganglionic myocardial sympathetic nerve fibers in patients with Parkinson's disease and autonomic failure . HoweverFurther effects of autonomic cardiovascular dysfunction are demonstrated in earlier studies such as baroreceptor reflex dysfunction, alterations in circadian blood pressure regulation, and supine hypertension \u201315. FindAmbulatory blood pressure monitoring is frequently used in the diagnosis and therapy monitoring of arterial hypertension and allows an evaluation of the circadian blood pressure evaluation , 18.The aim of this study was to identify patients with Parkinson's disease who showed loss or decrease of nocturnal blood pressure fall (non dipper patients) as a potential marker of autonomic dysfunction.Presence or absence of orthostatic hypotension was considered to investigate whether alterations in circadian blood pressure pattern are associated with posture-related dysregulation of blood pressure.40 patients with Parkinson's disease underwent ambulatory 24-hour blood pressure monitoring. Parkinson's Disease was diagnosed according to the criteria of the United Kingdom Parkinson's disease Society Brain Bank . None ha20 of the patients were male, 20 were female; they were aged 41 to 82 years ; disease duration (Parkinson's disease) was 1 to 152 months (mean disease duration 49 months) . 21 patiLong-term blood pressure measurements were performed with \u201cMobilograph,\u201d an oscillometric recorder . Patients were asked to maintain their normal physical activity. Nondipper patients were defined as having nocturnal decrease of mean systolic and diastolic blood pressure less than 10%. Presence or absence of orthostatic hypotension was determined by Schellong's test ; orthostatic hypotension was defined as a minimum decrease in systolic and/or diastolic blood pressure of 20\u2009mmHg or 10\u2009mmHg, respectively, on standing at the third minute .Results are presented as mean values (\u00b1 standard deviation (SD)). A correlation analysis was performed between the presence of loss of nocturnal blood pressure fall and disease duration, age and presence of arterial hypertension/use of antihypertensive medication.Ambulatory blood pressure was recorded without interruption in all patients with a mean measurement period of 23 hours . The average number of measurements obtained during the 24-hour recording was 88% (\u00b1 11). Results of the mean diurnal arterial pressure showed 18 patients with hypertensive blood pressure values and 22 patients with normal blood pressure. Beside the 21 patients who were already diagnosed with arterial hypertension 6 patients showed hypertensive blood pressure values in ambulatory blood pressure recording; thus a total of 27 patients (68%) had arterial hypertension .We identified 35 non dipper patients (88%) among 40 examined patients with Parkinson's disease; 25 patients (63%) showed nocturnal increase of blood pressure . CorrelaAutonomic test results showed 21 patients with orthostatic hypotension. Loss of nocturnal blood pressure fall was detected in 20 patients with orthostatic hypotension (95%); this was also detected in 15 patients without orthostatic hypotension (79%). We found 11 patients with supine hypertension who were non dipper (100%) and 24 patients without supine hypertension who were non dipper (83%) .We investigated ambulatory blood pressure monitorings in patients with Parkinson's disease to evaluate the circadian blood pressure profile, especially the presence or absence of loss of nocturnal blood pressure fall (non dipper). Results of earlier studies show a variable percentage of non dipper patients , mainly Our results show that most of our examined patients with Parkinson's disease were non dipper (88%); this was even found in 79% of the patients without orthostatic hypotension. In conclusion, ambulatory blood pressure monitoring could be useful to detect autonomic dysfunction even in the early stages of Parkinson's disease when orthostatic hypotension is not present. \u03b1-adrenergic receptors due to sympathetic denervation in patients with Parkinson's disease may contribute to supine hypertension during the night due to exaggerated vasoconstriction [The alterations in the circadian blood pressure profile may be caused by impairment of the autonomic regulatory mechanisms, possibly through postural dysregulation of blood pressure as mentioned in earlier reports . This dytriction , 23, 24.Presence or absence of arterial hypertension was additionally investigated in our patients to evaluate a possible association with loss of nocturnal blood pressure fall; there was no correlation between the presence of non-dipping and the presence of arterial hypertension or use of antihypertensive medication. 27 patients were additionally diagnosed with arterial hypertension or had hypertensive blood pressure values in ambulatory blood pressure recording (68%). 24-hour blood pressure monitoring should be performed in patients with Parkinson's disease and coexisting arterial hypertension, who are treated with antihypertensive medication. For prevention of an increased prevalence of end-organ damage we propose treatment of nocturnal hypertension in patients with Parkinson's disease. Treatment with antihypertensive drugs in patients with orthostatic hypotension may be complicated by worsening of the postural blood pressure fall in the upright position in these patients and thus may cause syncopes or cerebral ischemia. Consequently, vasoactive drugs should be used carefully in patients with Parkinson's disease and autonomic dysfunction. Alternatively sleeping in a 12\u00b0 head-up tilt position may be helpful . Concerning an increased cardio\u2014and cerebrovascular risk in patients with nondipping, Corn\u00e9lissen et al. showed that\u2014compared with dipping\u2014abnormal chronobiological end points such as reduced circadian standard deviation of heart rate or elevated pulse pressure are more useful to discriminate between patients who are at a higher risk and who are not . HoweverIn conclusion 24-hour ambulatory blood pressure monitoring showed a high prevalence of non-dipping in 40 patients with Parkinson's disease with and without orthostatic hypotension independent of the coexisting arterial hypertension, and antihypertensive treatment. Our data strengthens the role of ambulatory blood pressure recording for detection of non-dipping not only in patients with orthostatic hypotension, but also in patients without orthostatic hypotension. Beside other autonomic tests 24-hour blood pressure monitoring may be helpful to support the detection of autonomic dysfunction in patients with Parkinson's disease even in the early stages of the disease."} +{"text": "There is an error in the legend for Figure 3.

Reads were trimmed using the FASTX toolkit and aligned to hg19 using Bowtie. Reads mapping to a microRNA locus were grouped into those with the canonical seed and those with an alternative seed due to variation in the 5' start position (isomiRs). Negative binomial generalized linear models were used to identify microRNAs and isomiRs differentially expressed between phenotypes.

Results indicated relatively rich genetic diversity (He = 0.63-0.65) in Italian rice varieties. Further analyses revealed a close genetic relationship of the Italian traditional varieties with those from northern China, which provides strong genetic evidence for tracing the possible origin of early established rice varieties in Italy. These findings have significant implications for the rice breeding programs, in which appropriate germplasm can be selected from a given region and utilized for transferring unique genetic traits based on its genetic diversity and evolutionary relationships.The characterization of genetic divergence and relationships of a set of germplasm is essential for its efficient applications in crop breeding and understanding of the origin/evolution of crop varieties from a given geographical region. As the largest rice producing country in Europe, Italy holds rice germplasm with abundant genetic diversity. Although Italian rice varieties and the traditional ones in particular have played important roles in rice production and breeding, knowledge concerning the origin and evolution of Italian traditional varieties is still limited. To solve the puzzle of Italian rice origin, we characterized genetic divergence and relationships of 348 rice varieties from Italy and Asia based on the polymorphisms of microsatellite fingerprints.

Nearly all rice varieties grown in Italy are japonica ecotype [Italy is the largest rice production country in Europe, with about 250,000 hectares of cultivation area , although no written document about these is available. The earliest rice cultivation documented in Italy can be traced back to 1468 in the wetlands of Tuscany, near Pisa [Magnaporthe oryzae). To guarantee the continued rice cultivation that was seriously threatened by this fungal disease, new varieties were introduced from China and Japan at the beginning of 19th century. These varieties were characterized by their high yielding and resistance to rice blast. As a consequence, five Italian rice varieties were cultivated in Italy in 1872: Ostiglia, Bertone, Novarese, Francone, and Giapponese. Because of the recrudescence of blast attacks that created a new crisis for Italian rice cultivation, more rice varieties were imported from Asian countries including China, India, and Japan in 1880, which led to a substantial increase in the number of Italian rice varieties in the subsequent years. A milestone of Italian rice cultivation in history was the presence of a set of varieties grouped under the general name of \u201cChinese Originario\u201d with high yield and strong resistance to blast [The first official documentation of rice introduction to Italy is related to the Spanish Presence in the Kingdom of Naples because of the ties between the Aragon family (The Kings of Naples) and the Sforza family (Dukes of Milan) in the second half of 15 century .

In addition, Italian rice germplasm as a whole showed a relatively distant genetic affinity with that from South Asia and Southeast Asia, where varieties, it makeindica and japonica differentiation as suggested by other studies [Notably, the Italian traditional and locally improved rice varieties have a close genetic affinity with Chinese and East Asian varieties. When alien germplasm was introduced from North America and used as breeding materials for hybridization, the genetic relationship between Italy-3 and Chinese/East Asian rice varieties became loose due to mixture of North America rice germplasm.

The intindica and japonica rice varieties [Our results generally indicated a close relationship of Italian traditional and locally bred modern varieties to Chinese varieties as a whole group. However, China is a large country with the extensive cultivation of diverse types of arieties ,23,24. IOur results based on genetic similarity analysis of Italian traditional varieties with Chinese rice germplasm represented by different Provinces evidently indicated their close genetic affinity to that from northern rice cultivation regions . These rAlthough the tales such as Marco Polo\u2019s contribution to the introduction of rice from China to Italy may never be fully confirmed, results from this study provide solid genetic evidence to confirm the close linkage between Italian and Chinese rice varieties. Rice varieties from northern China may provide genetically most accessible and useful germplasm for Italian rice breeding because of their close genetic relatedness and abundant genetic diversity, even though rice varieties from other regions in Asia can also provide unique and especially valuable germplasm that has not been represented in the Italian rice gene pool. As the largest rice production country in Europe, Italy holds important and diverse rice germplasm, which guarantees the sustainable rice production and breeding in Italy and neighboring countries. Knowledge concerning the genetic diversity, origin, and evolutionary relationships of Italian rice has important implications for its effective breeding by selecting proper exotic rice germplasm. The early introduced rice varieties such as \u201cChinese originario\u201d have played an important role in Italian rice production and breeding programs. However, the origin and evolutionary relationships of these early introduced varieties have not been properly documented. Results based on SSR fingerprints of a large set of rice germplasm from Italy and Asia in this study demonstrate a close genetic relationship between Italian and Chinese rice varieties, suggesting the possible origin of Italian traditional rice from northern China. Although the conclusion on Chinese origin of Italian traditional rice still needs supports from further studies, this finding has significant implications for Italian rice improvement by including appropriate exotic germplasm in its breeding programs.Figure S1A Neighbor-Joining (NJ) tree showing individual-based genetic relationships of 348 rice varieties analyzed in this study (see Table 1 and Table S1 for detail information), using wild rice as an out-group (root).

To investigate this interplay, we analyzed fluctuations in coastal phytoplankton concentration in relation to the tidal cycle. Time series of chlorophyll fluorescence, suspended particulate matter (SPM), salinity and temperature were obtained from an automated measuring platform in the southern North Sea, covering 9 years of data at a resolution of 12 to 30 minutes. Wavelet analysis showed that chlorophyll fluctuations were dominated by periodicities of 6 hours 12 min, 12 hours 25 min, 24 hours and 15 days, which correspond to the typical periodicities of tidal current speeds, the semidiurnal tidal cycle, the day-night cycle, and the spring-neap tidal cycle, respectively. During most of the year, chlorophyll and SPM fluctuated in phase with tidal current speed, indicative of alternating periods of sinking and vertical mixing of algal cells and SPM driven by the tidal cycle. Spring blooms slowly built up over several spring-neap tidal cycles, and subsequently expanded in late spring when a strong decline of the SPM concentration during neap tide enabled a temporary \u201cescape\u201d of the chlorophyll concentration from the tidal mixing regime. Our results demonstrate that the tidal cycle is a major determinant of phytoplankton fluctuations at several different time scales. These findings imply that high-resolution monitoring programs are essential to capture the natural variability of phytoplankton in coastal waters. What drives fluctuations in population abundances? In the 1920s the famous zoologist Charles Elton argued that population fluctuations of many birds and mammals are most likely due to climatic fluctuations This interplay between intrinsic population processes and external forcing is exemplified by the plankton of freshwater and marine ecosystems. Theory and experiments have shown that plankton communities can display striking fluctuations, and even chaos, under constant conditions without external forcing Environmental forcing by the tidal cycle is an important driver of phytoplankton variability in coastal waters We hypothesize that these different sources of phytoplankton variability can be distinguished by investigating the time scales of phytoplankton fluctuations. For instance, phytoplankton fluctuations with a periodicity of 6 hours 12 min indicate an alternation between entrainment of sinking phytoplankton into the surface layer during high tidal current speeds and settlement of sinking phytoplankton during tidal slacks. A periodicity of 12 hours 25 min indicates changes in phytoplankton concentration due to horizontal transport of different water masses. A 24 hour periodicity would signal environmental forcing by the day-night cycle , which would be very different from the 24 hour 50 min periodicity of a mixed semidiurnal tide. At longer time scales, the spring-neap cycle and apogee-perigee cycle generate variation in the intensity of tidal mixing that could affect phytoplankton populations.Furthermore, we hypothesize that the impact of environmental forcing on phytoplankton population dynamics will depend on the relative magnitude of intrinsic population growth versus environmental forcing. For instance, settling and resuspension of phytoplankton in shallow coastal waters depends on the vertical mixing intensity generated by wind action and tidal motion To investigate these hypotheses, we analyze phytoplankton fluctuations in a high-resolution time series obtained from an automated mooring station in the coastal North Sea. The mooring measured chlorophyll fluorescence, suspended particulate matter (SPM), nitrate, salinity, temperature and irradiance at a high temporal resolution for a period of nine years. Earlier analysis of the first year of this time series showed that the phytoplankton spring bloom was initiated by an improved light availability in spring, due to a combination of enhanced solar radiation and reduced SPM concentrations We analyzed data of mooring station Warp, located in the coastal waters of the southern North Sea near the Thames Estuary . The maihttp://www.cefas.defra.gov.uk. More information on the methodology and application of SmartBuoys can be found in Kr\u00f6ger et al. At the mooring station an automated measuring platform, called a \u2018SmartBuoy\u2019, has been deployed from 30 November 2000 onwards, as part of the United Kingdom\u2019s eutrophication monitoring program in situ Seapoint fluorometer measurements versus extracted chlorophyll concentrations in the water samples had a R2 of 0.86 when averaged over all monthly samples. Although chlorophyll fluorescence is a very convenient measurement technique, it is known that the fluorescence signal can be quenched when cells are exposed to high light Chlorophyll fluorescence was measured with a Seapoint fluorometer (Seapoint Inc.). Fluorescence data were calibrated against chlorophyll concentrations in water samples taken during monthly service visits to the mooring stations. Chlorophyll concentrations were measured by filtering known sample volumes through glass fiber filters in triplicate. Pigments were immediately extracted in 90% buffered acetone and refrigerated prior to analysis. A Turner Designs Model 10AU filter fluorometer was used to measure the fluorescence of extracted chlorophyll and phaeopigment before and after acidification as described by Tett in situ Seapoint turbidity measurements versus SPM concentrations in the water samples had a R2 of 0.72 when averaged over all monthly samples.Optical backscatter was measured with a Seapoint turbidity meter (Seapoint Inc.), and converted to SPM concentration using calibration against monthly water samples. SPM concentrations in the samples were measured by filtering known sample volumes through pre-weighed 0.4 \u00b5m polycarbonate filters and subsequent rinsing with 2\u00d750 mL ultrapure water. Filters were then dried in a desiccator at room temperature and weighed until filter weight remained constant. Calibration curves of The concentration of total oxidisable nitrogen (hereafter referred to as nitrate) was measured with a NAS-3X nutrient analyzer (EnviroTech). Salinity and temperature were measured using an FSI CT sensor . Salinity measurements were calibrated using a Guildline 8400B salinometer, which had been standardized with IAPSO standard seawater. Downwelling PAR was measured at 1 and 2 m depth using two LiCor (LI-192) underwater quantum sensors (LiCor Biosciences).The SmartBuoy measurements went through a Quality Assurance protocol within the SmartBuoy Data Management System, checking all data manually for possible sensor malfunction and biofouling. For instance, fluorescence measurements directly before each monthly service were compared with those directly after monthly service to identify signatures of biofouling. Data that looked suspect were flagged and not used in the analyses.Phytoplankton species composition at the mooring station was determined on an approximately monthly basis. Water samples (150 mL) taken at 1 m depth were preserved with 2.5 mL acidified Lugol\u2019s solution, and analyzed by inverted microscope after 12 hours of settling in a 25-mL glass chamber Tidal data were obtained from a tide gauge at the nearby coastal station Sheerness . Inspect\u00b5mol quanta m\u22122 s\u22121), to remove possible effects of non-photochemical quenching of chlorophyll fluorescence. We analyzed the hourly averaged and daily averaged time series separately to investigate variability at different time scales.Because the sampling interval of the automated measurements varied between instruments and between years, we calculated hourly averages to obtain a more uniform dataset. We also calculated daily averages of all variables, where the chlorophyll data were confined to measurements made in the dark to reduce the effect of small-scale variability caused by e.g. measurement noise, intermittent turbulence or local patchiness. We used these small intervals for the moving average filter to avoid smoothing out relevant periodicities of the tidal cycle. Third, we calculated the rates of change from the difference between the data values at time t and time t-\u0394t, where \u0394t represents a single time step of one hour or one day. Because we had log-transformed the data, this procedure effectively resulted in a time series of the relative rates of change (\u2018relative growth rates\u2019) of the measured variables, since.We analyzed the rates of change of the data instead of their concentrations, because concentrations are the result of growth and decay processes during the preceding period whereas instantaneous rates of changes better reflect the conditions at the time of measurement.We used wavelet analysis We applied wavelet coherence, an extension of wavelet analysis, to investigate the \u2018coherence\u2019 of two time series http://www.pol.ac.uk/home/research/waveletcoherence/).The statistical significance of periodicities revealed by wavelet analysis was tested by comparing the wavelet power spectrum of our time series against the 95% confidence level of wavelet power spectra generated by red noise, using an autoregressive AR1 model with the same autocorrelation coefficient as our time series Our time series contained several data gaps. Small gaps of at most one data point were filled by linear interpolation. Larger gaps could not be filled by interpolation without affecting the results. Therefore, we calculated separate wavelet power spectra for all subsets of the time series with a sufficient number of consecutive data points. Wavelet analysis can accurately detect periodicities up to \u223c25% of the length of a time series Phaeocystis). Most abundant were chain-forming diatoms , and benthic diatoms .Time series of water level, chlorophyll, SPM, nitrate, light intensity, temperature and salinity all displayed strong variability at several different time scales , S8, S9.Light intensity (PAR) at 1 m depth followed the expected seasonal pattern, but with distinct daily and biweekly variation . High liWe first analyzed the tidal data measured at station Sheerness . In lineThe spring-neap cycle is clearly visible in the time series of the tidal range . Close iWavelet analysis of the hourly-averaged chlorophyll concentration of the year 2007 reveals significant periodicities of 6 hours 12 min and 12 hours 25 min during most of the year, and an additional 24-hour periodicity in late spring and summer only . LikewisComparison with the tidal data reveals that chlorophyll concentrations consistently peaked a few hours before high tide and a few hours before low tide . The timTaking the absolute value transforms the 12 hour 25 min periodicity of the water level to a 6 hour 12 min periodicity in tidal current speed. Indeed, the rate of change in chlorophyll concentration seems to fluctuate in phase with tidal current speed .This phase relationship can be tested by wavelet coherence analysis, which displays the coherence (colors) and phase angles (arrows) between two fluctuating time series. Bold black lines delineate areas of significant coherence. Arrows pointing to the right indicate in-phase fluctuations. This confirms that the rate of change in chlorophyll concentration fluctuated in phase with tidal current speed at a significant 6-hour periodicity . In otheIn Wavelet coherence analysis shows that the chlorophyll concentration fluctuated in phase with the tidal range and SPM This sequence of events, where a strong decline of the SPM concentration in late April or early May was accompanied by a large spring bloom, was also observed in the years 2001, 2003, 2004 and 2008 , S8, S9.\u22123 of chlorophyll should contribute 100 mg m\u22123 of SPM. In view of the measured concentrations of chlorophyll and SPM in our time series, this implies that phytoplankton comprised less than 5% of the SPM concentration throughout the entire year, except during the spring bloom when phytoplankton increased to \u223c20% of total SPM. However, during the spring bloom the phytoplankton dynamics diverged from the SPM dynamics, as the decline in SPM concentration was accompanied by a rise in chlorophyll concentration. For these reasons, the in-phase fluctuations of chlorophyll and SPM cannot be explained by the assumption that SPM consisted mostly of phytoplankton particles.Our results show that short-term fluctuations of coastal phytoplankton were dominated by periodicities of 6 hours 12 min, 12 hours 25 min, and to a lesser extent 24 hours, reflecting the typical periodicities in tidal current speed, horizontal displacement of tidal waters, and the day-night cycle, respectively. Likewise, SPM also fluctuated at 6-hour and 12-hour periodicities, in phase with the chlorophyll fluctuations. One possible explanation for the in-phase fluctuations of chlorophyll and SPM could be that SPM is largely composed of phytoplankton. We therefore estimated the relative contribution of phytoplankton to SPM. Assuming a phytoplankton biomass to carbon ratio of 2.5 Cylindrotheca, Paralia, Plagiogrammopsis), which combine a benthic and pelagic life style as they commonly settle on the sediment during weak mixing but are resuspended during intense tidal mixing Instead, we hypothesize that the 6-hour periodicity and in-phase dynamics of chlorophyll and SPM are explained by alternating sinking and vertical mixing of phytoplankton and SPM driven by the tidal cycle. Phytoplankton and SPM both have a particulate nature. Hence, surface concentrations of phytoplankton and SPM will decrease simultaneously due to sedimentation during weak turbulent mixing . Conversely, phytoplankton and SPM will increase simultaneously by resuspension during periods of intense tidal mixing generated by the high current speeds between each high and low tide. This explanation is supported by the in-phase fluctuations of the chlorophyll dynamics and tidal current speed . In fact\u22121\u22121Sinking rates of single diatom cells range from near zero to 10 m dSalinity, nitrate and temperature are not subject to sedimentation and resuspension by tidal mixing. Indeed, salinity, nitrate and temperature showed only minor 6-hour periodicity, but fluctuated predominantly at a periodicity of 12 hours 25 min. This periodicity matches the typical time scale of horizontal displacement of water masses moving back and forth by tidal motion. Horizontal transport of different water masses is further confirmed by the observation that salinity fluctuated in phase with water level, while nitrate fluctuated in anti-phase with water level at a 12-hour 25-min periodicity . This reAn additional process contributing to the 12 hour 25 min periodicity might be the vertical excursions of the SmartBuoy, which moved up and down with the water level. This could be particularly relevant in waters with strong vertical gradients of the chlorophyll and SPM concentrations in the upper meters of the water column, where the measurements are made. At station Warp, however, the upper meters of the water column are well mixed . TherefoIn summer, we also found a 24-hour periodicity in chlorophyll fluorescence, but not in SPM. The 24-hour periodicity was less pronounced than the periodicities at 6 hours 12 min and 12 hours 25 min. Wavelet analysis indicates that this 24-hour periodicity is independent of the tidal periodicity, because the peak of the global power spectrum was located at 24 hours sharp rather than at 24 hours 50 min. This day-night cycle is probably caused by non-photochemical quenching of the fluorescence signal during sunny days. Alternatively, this day-night cycle might reflect diurnal variation in convective mixing driven by thermal micro-stratification during the daytime and surface cooling at night. Van Haren et al. Superimposed upon the 6-, 12- and 24-hour periodicities the chlorophyll concentration also fluctuated at a significant 15-day periodicity, in phase with the spring-neap tidal cycle. A possible explanation for the 15-day periodicity in phytoplankton abundance is that the spring-neap cycle modulated the nutrient supply. This mechanism was described by Sharples et al. 2. Hence, the chlorophyll and SPM fluctuations observed at the time scale of the spring-neap cycle will probably not represent small-scale processes restricted to the local neighborhood of station Warp, but may integrate sedimentation and resuspension over a large area. The 15-day periodicity of the SPM concentration confirms recent spectral analyses of remote sensing data of the North Sea, which indicated spring-neap variations in SPM in the East Anglia plume and Rhine plume Instead, the in-phase fluctuations of both chlorophyll and SPM with the tidal range suggest that a large fraction of the phytoplankton and SPM sinks to the sediment or deeper water layers during calm conditions at neap tide, while they are resuspended by strong tidal mixing during spring tide. Station Warp is part of a large shallow outer estuary of more than 100 kmEarlier analysis indicated that the spring bloom at our coastal mooring site is triggered by improved light conditions due to a combination of enhanced solar radiation and reduced SPM concentrations in spring What caused the conspicuous decline of the SPM concentration in mid spring? It might be induced by a strong reduction in tidal range, weakening tidal mixing and thereby enhancing sedimentation of SPM. For instance, the strong SPM decline in early May 2007 occurred when spring tide coincided with apogee of the moon, resulting in a weak spring tide . LikewisThe phytoplankton spring bloom resulted in rapid depletion of inorganic nutrients, which was followed by lower phytoplankton concentrations during the remainder of the summer. This classic pattern was also observed in the earlier study of Weston et al. Prorocentrum micans and Peridinium trochoideum) aggregated near the water surface during slack water, while they became homogeneously distributed when tidal mixing intensified. Conversely, large pelagic diatoms (Coscinodiscus spp.) relied on enhanced turbulent mixing during ebb and flood currents to prevent sinking from the photic zone. In view of these studies, it seems quite plausible that the 6-hour periodicity in chlorophyll concentration observed in our tidal system may also be accompanied by a concomitant 6-hour periodicity in phytoplankton species composition, due to species-specific differences in vertical dispersal by the tidal cycle.Temporal variation in turbulent mixing may result in temporal variation in the phytoplankton community. For instance, Huisman et al. According to the intermediate disturbance hypothesis, biodiversity will be highest in ecosystems exposed to intermediate frequencies of environmental forcing The superposition of several periodic fluctuations in chlorophyll concentration and phytoplankton species composition are a challenge for the design of marine monitoring strategies. Measurements taken at fixed time intervals that are not commensurate with the natural frequencies of the tidal cycle may introduce structural biases in monitoring data. For instance, the semidiurnal tidal cycle takes slightly longer than 12 hours. Hence, if measurements are taken, say, once every day at noon, this may erroneously suggest large changes in phytoplankton concentration over a period of several days, while these data simply represent different phases of the semidiurnal tidal cycle. Likewise, the spring-neap cycle takes slightly longer than 14 days. Hence, if a water body is sampled once every two weeks, then the data may erroneously suggest large changes in phytoplankton concentration and phytoplankton species composition over a period of several months, while these data actually reflect different phases of the spring-neap cycle. To avoid such structural biases, the temporal resolution of the measurements should be sufficiently refined to capture the periodicities in the system. In practice, this implies that chlorophyll concentrations should be measured at minimum time intervals of \u223c1 hour to capture the semidiurnal tidal cycle. Alternatively, if resources are limited, one might consider measuring less frequently but always at the same moments with respect to both the semidiurnal and spring-neap tidal cycle. In those marine ecosystems where the tidal cycle is a key determinant of chlorophyll variability, it will be difficult to make sense of phytoplankton data obtained from low-frequency sampling programs ignoring the tidal periodicities.Our results show that careful investigation of the time scales of population fluctuations in relation to environmental forcing can reveal much information on the underlying processes. We found that phytoplankton fluctuations in the southern North Sea reflect different oscillatory modes of the tidal cycle, including variation in tidal current speeds (6 hours 12 min), horizontal water motion (12 hours 25 min) and the spring-neap tidal cycle (15 days). A weaker 24-hour periodicity was also observed. During most of the year, chlorophyll and SPM concentrations fluctuated in phase with the tidal cyle, indicative of alternating periods of sedimentation and resuspension. However, phytoplankton escaped from the spring-neap tidal cycle in spring, when a strong decline in SPM concentration led to improved light conditions. Hence, fluctuations of coastal phytoplankton were strongly driven by external forcing, but intrinsic population processes took over when growth rates were high during the spring bloom. Our findings illustrate that high-resolution monitoring is required to capture this natural variability, which is considered an essential first step for the reliable detection and prediction of the long-term response of coastal phytoplankton to changing environmental conditions.Figure S1Contour plots of water density.

The Child Health Questionnaire (CHQ-PF 50) was used to assess the health related quality of life.Rapid clinical and laboratory improvement was observed in all patients, but six patients who declined treatment and experienced progressive course of the disease. All the treated patients maintained persistent remission; 5 patients required an increase of the dosage to 300 mg per day. No adverse effects were recorded except injection site reactions.Until today, 8 of the 16 patients initially treated with Anakinra have subsequently switched to Canakinumab at the initial dose of 150 mg every 8 weeks.IL-1 inhibition seems to be crucial in modifying the natural history of CAPS. Long-term follow up of patients treated with Anakinra established its efficacy and tolerability. The same evaluation will be done for Canakinumab, that appears to be equally effective but whose side effects still need to be evaluated. The bimonthly administration of Canakinumab may be certainly useful, especially in pediatric population, however its long half-life implies a tight surveilance in case of infections."} +{"text": "The objective of this study was to systematically review the medical literature for the prevalence of waterpipe tobacco use among the general and specific populations.We electronically searched MEDLINE, EMBASE, and the ISI the Web of Science.

Pathological etiology is deposition of hemosiderin (a product of the breakdown of blood) in leptomeninges, subpial layer, ependymal surface and other parts of central nervous system (CNS) and typically leads to neurological dysfunction and progressive irreversible signs and symptoms. We present a 33-year-old man with complete deafness in left ear, partial hearing loss in right ear, gait imbalance, bilateral frontotemporal throbbing headache and anosmia resulted from superficial siderosis. His familial history was noncontributory.Neurological examination revealed a good alert patient with no evidence of cognitive impairment, horizontal nystagmus in both eyes with normal saccade and pursuit, normal force and tone of muscle with decreased light touch and pin prink with stocks and gloves pattern, severe dysmetria and moderate dysdiadochokinesia, generalized hyperreflexia, bilateral equivocal plantar reflexes, and ataxic gait with impossibility to perform tandem gait.Audiogram showed bilateral, high-frequency sensorineural hearing loss especially in left side.Magnetic resonance imaging (MRI) findings are shown in 2 It was first described in 1908 by Hamill; but with no access to modern technology and MRI, the only diagnostic way was biopsy.2 Using the results of 270 reported cases of SS in articles from 1908 to 2006 revealed different causes for this disease;2 some of the most frequent ones are Idiopathic (35%), head or neck trauma (13%), AVM (9%), current CNS tumor (15%), previously resected CNS tumor (6%), post CNS surgery (non-tumor) (7%), amyloid angiopathy (3%), brachial plexus injury (6%), and other cause of subarachnoid hemorrhage (6%).5 The probable cause in the presented case was recurrent head trauma in his childhood.Superficial siderosis (SS) is a rare disease affects people in all ages and both sexes but three times more in men.4 and as the result of these depositions and central nervous system involvement; there are progressive, irreversible clinical manifestations of the disease; the most common one is sensorineural hearing loss which over a period of 1 to 12 years progresses to total deafness.2 In our case, hearing loss and loss of sense of smell began at the age of 20 and over 13 years developed to complete deafness and anosmia. The second most common sign is gait imbalance and ataxia which was also in our case a remarkable, slowly progressive problem.After breaking down of erythrocytes or red blood cells exiting in CSF and CNS, hemoglobin and iron-containing heme are released in CSF and in response to this upsurge in heme levels, Bergmann glia and microglia cells produce heme oxygenase-I enzyme which breaks down free heme into biliverdin, carbon monoxide and iron. The deposition of iron in cerebral tissue is the main pathology of superficial siderosis2 The largest review of the literature to date, reported that patients presented with bilateral SNHL (95%), ataxia (88%), and pyramidal tract signs (46%);6 cerebellar dysarthria is common and nystagmus may be present.7 But, sensory symptoms or a sensory level are uncommon.8Using the result of 270 reported cases of SS, the most common features of the disease are hearing loss (81%), ataxia (81%), myelopathy (53%), urinary problems (14%), headache (14%), anosmia (14%), diplopia (4%), bowel problems (3%), and cranial nerve palsies (2%).2 and optic or trigeminal neuropathy9 also are uncommon but have been reported. In approximately one third of the cases in an earlier literature review,2 severe recurrent headaches which were indicative for symptomatic subarachnoid hemorrhage were reported; but was infrequent in recent large studies.10Extraocular nerve palsies11The first step for early detection of SS is via MRI which shows iron depositions in affected tissues as a hypointense band, and characteristic rim of intensity appearing on the cerebellum, with no enhancement These signal loss areas in T2-weighted scans are pathognomonic for the disease, but hyperintense rime is also rarely seen.11 Iron or copper chelators and steroids are other treatments but with little success.12 In one study, using oral deferiprone (a lipid-soluble iron chelator with ability to cross the blood-brain barrier) at a dose of 30 mg/kg per day has been caused reduction of hemosiderin deposition in MRI;13 and the usage of trientine also has been reported to reduce iron concentration in CSF.14There is no successful or specific treatment for SS. With early detection of source of bleeding, the surgery may be helpful.In conclusion, according to our literature review, SS with CNS involvement is a rare disorder which formed because of the deposition of hemosiderin in leptomeninges, subpial layer, ependymal surface and other parts of CNS and leads to neurological dysfunction and progressive irreversible signs and symptoms. In our case, hearing loss and loss of sense of smell began at age of 20 and over 13 years developed to complete deafness and anosmia. There is no successful or specific treatment for SS but Iron or copper chelators and steroids are some treatments with little success."} +{"text": "Identification of the genetic differences between the two lesions may assist in identifying genes that promote the invasive phenotype.

Matched IDC and DCIS showed highly similar copy number profiles (average of 83% of the genome shared). Four regions of loss and four regions of gain were recurrently affected in IDC but not in the matching DCIS. CCND1 and MYC showed increased amplitude of gain in IDC. One region of loss (17p11.2) was specific to DCIS. Our data shows that DCIS is an advanced pre-invasive tumour with genetic instability and continues to evolve in parallel with co-existing IDC.

A secondary school having girl students in the age group of 12\u201315 years studying in sixth to ninth standard was selected. Serum ferritin concentration was estimated by ELISA. For assessing the cognitive function mathematics score, one multi-component test for memory, attention and verbal learning and Intelligent Quotient scores of the students were used. Results. Scholastic Performance, IQ and Scores of Mental balance, Attention & Concentration, Verbal Memory and Recognition were decreased in iron deficient girls, both anemic and non anemic as compared to the non iron deficient girls.Iron deficiency anemia is most common nutritional deficiency disorder in India and remains a formidable health challenge. Girls in the period of later school age and early adolescence are prone to develop iron deficiency. Iron deficiency leads to many non-hematological disturbances which include growth and development, depressed immune function in infants; reduces physical work capacity; decreases the cognitive function in both infants and adolescents. Present study was done to know the prevalence of iron deficiency in both the anemic and non anemic school going adolescent girls, to assess the effect of iron deficiency on cognitive functions in anemic iron deficient and non-anemic iron deficient school girls in a village school situated in central India. Iron deficiency is the third greatest global health risk after obesity and unsafe sex . Anemia Iron deficiency has both physiologic and pathologic causes. Physiologic causes relate to the greater iron demands during periods of growth and development whereas pathologic causes refer to iron losses secondary to a chronic medical condition. In general, iron deficiency results when iron demands by the body are not met by iron absorption. Thus, iron deficiency can result from inadequate intake, impaired absorption, increased requirements, and chronic blood loss.More than half of the world's undernourished population lives in India and halfIron deficiency is a systemic condition which has many non ematological consequences, which occurs in relation to its severity, like decreased physical work capacity , decreasIn present study, effort has been made to assess the effect of iron deficiency on cognitive functions in anemic iron deficient and in nonanemic iron deficient school going adolescent girls in a village school.The present study was carried out in the Department of Pathology, MGIMS, Sevagram, India from July 2007 to September 2009. Approval was obtained from the Institutional Ethics Committee for the study.A secondary school in the neighborhood, having girl students in the age group of 12\u221215 years studying in sixth to ninth standard was selected. Necessary permission was taken from the school authority and girls were explained in detail about the study in the school assembly. Participation in the screening programme was voluntary. An explanatory letter and consent form was given to all the girls. Written consent was obtained from parents or guardian for participation in the screening as all participants were minor. Participants completed a questionnaire asking for significant family, medical and menstrual history, parent education, and their dietary habits.Screening for anemia and iron deficiency was done by (1) complete blood count: done by automatic cell counter, that is, Coulter for hemoglobin concentration. (2) estimation of serum ferritin concentration was done by ELISA. For this recommended protocol by the kit used was followed. Established age adjusted values for hemoglobin and serum ferritin were used.Group I\u2014participants who were anemic (Hb < 12\u2009gm%) and iron deficient (serum ferritin less than 12\u2009\u03bcg/L).Group II\u2014participants who were nonanemic (Hb \u2265 12\u2009gm%) and iron deficient (serum ferritin less than 12\u2009\u03bcg/L).Group III\u2014participants who were nonanemic (Hb \u2265 12\u2009gm%) and noniron deficient (serum ferritin levels of 12\u2009\u03bcg/L or more).The participants after screening were divided into three groups.After dividing the participants into three groups, that is, anemic iron deficient (group I), nonanemic iron deficient (group II), and nonanemic noniron deficient (group III), for assessing the cognitive function mathematics score, one multicomponent test for memory, attention and verbal learning, and intelligent quotient (IQ) scores of the students was used.For assessment of scholastic performance, the mathematics score obtained in the final term examination was noted from the report card. The score obtained were from total 100 marks.Multicomponent test of the three groups was assessed after randomization by using PGI test\u2014(Dr. N. N. Wig & Dr. Dwarka Prasad) for testing memory attention and verbal learning Both parPGI test\u2014(Dr. N. N. Wig & Dr. Dwarka Prasad), consisted of the following ten subtests: (I) remote memory, (II) recent memory, (III) mental balance, (IV) attention and concentration, (V) delayed recall, (VI) immediate memory, and (VII) verbal retention for similar pairs, (VIII) verbal retention with dissimilar pairs, (IX) visual retention, and (X) recognition.For assessing the intelligent quotient of the girl student's, Bhatia battery performance test\u2014(Dr. C. M. Bhatia) for intelligent quotient (I.Q) was used, which includes two subtest Kohl's block design and Pass along test .Statistical analysis: the data was analyzed with SPSS (version 16) statistical software. One-way ANOVAs test 63 of 100 girl students had hemoglobin levels less than 12\u2009gm% and 37 had hemoglobin levels above 12\u2009gm%. Thus, prevalence of anemia in school going adolescent girls was 63%. The overall mean hemoglobin in the study was 11.66 \u00b1 1.27\u2009g/dL.Out of the 63 girl students who had anemia, 56 girls (56%) had Hb values between 10 and 12\u2009gm%, 5 girls (5%) had Hb values between 7 and 10\u2009gm%, and rest of the 2 girls (2%) had Hb values below 7\u2009gm%. Thus, mild anemia (Hb 10\u201312\u2009gm%) was present in 56% of the study subjects, moderate anemia (Hb 7\u201310\u2009gm%) in 5%, and severe anemia (Hb < 7\u2009gm%) was present in only 2% of the study subjects.\u03bcg/L). So the prevalence of iron deficiency was 67%.Serum ferritin was done in 100 girl students between the age group of 12\u221215 years, 67 were iron deficient between nonanemic noniron deficient (group III) and anemic iron deficient (group I), it was significant between nonanemic noniron deficient (group III) and nonanemic iron deficient (group II).The difference in mathematics score was highly significant (Multicomponent test (MCT) of verbal learning, attention, memory and IQ scores of all the three groups was assessed after randomization. Tests were administered under the guidance of trained research assistant of the Department of Psychological Medicine. The person who was assessing the tests was unaware of the group assignment.P value < 0.0001) and also the scores of mental balance differed significantly between the nonanemic noniron deficient (group III) and nonanemic iron deficient (group II). The difference in scores of attention and concentration was significant between non anemic noniron deficient (group III) and anemic iron deficient (group I). And the nonanemic iron deficient (group II) and nonanemic noniron deficient (group III) also showed statistically significant difference in scores of attention and concentration.The difference in scores of mental balance between the nonanemic noniron deficient (group III) and anemic iron deficient (group I) was significant , and on comparing the scores of Verbal Retention for Similar Pairs between the non-anemic iron deficient (group II) and non anemic non iron deficient (group III) the difference was also statistically significant .Non anemic non iron deficient (group III) and anemic iron deficient (group I) when compared for scores of Verbal Retention for Similar Pairs showed significant difference and also between the nonanemic iron deficient (group II) and nonanemic noniron deficient (group III) showed statistically significant difference .The difference in scores of verbal retention for dissimilar pairs between the anemic iron deficient (group I) and nonanemic iron deficient (group III) was statistically significant , similarly the difference in scores of recognition between the nonanemic iron deficient (group II) and nonanemic iron deficient (group III) were statistically significant .The scores of recognition between the anemic iron deficient (group I) and nonanemic iron deficient (group III) showed significant difference (For assessing the intelligent quotient (IQ) of the girl students two test, that is, Kohl's block design test and Pass along test were used. After obtaining the test quotient (TQ) from these two tests the IQ was calculated.P value < 0.0001 and also between nonanemic noniron deficient (group III) and nonanemic iron deficient (group II) .The IQ levels differed significantly between nonanemic noniron deficient (group III) and anemic iron deficient (group I) with Thus, the cognitive function scores which included the mathematics score, multicomponent test scores, and IQ scores were less in iron deficient both anemic and nonanemic groups (group I and II) than the noniron deficient nonanemic group (group III).Although all the features of cognition are important but verbal learning and attention and concentration along with memory are particularly more important for academic performance.In present study, iron deficient both anemic and nonanemic students had scored less in mathematics than the normal non iron deficient students. This is in accordance to the study done by Prestonjee wherein Multicomponent test of verbal learning, attention, and memory of all the three groups was assessed after randomization. The overall total score was less in iron deficient both anemic and nonanemic groups than noniron deficient nonanemic group.Similar findings were also seen in scores of mental balance and verbal retention for similar and dissimilar pairs. There was no difference in score of recent and remote memory, delayed and immediate recall, and visual retention subsets between iron deficient (group I and II) and noniron deficient (group III).The findings suggest that iron deficiency, even in the absence of anemia causes decrease in at least some aspect of cognitive functioning.The present findings are in accordance with the findings of a randomized trial done by Bruner et al. on nonanThe difference of mean IQ scores between iron deficient both anemic and nonanemic groups (I and II) and nonanemic noniron deficient was statistically significant.Pollitt et al. , SoemantThe findings of the present study are iron deficient school going adolescent females both anemic and nonanemic had low scholastic performance in the form of low mathematics score and low scores in verbal learning, attention, mental balance, and recognition component of multicomponent test along with low IQ scores than their noniron deficient comparers. Iron deficiency independently leads to decreased cognitive scores. Iron deficiency without anemia is the initial stage and as the iron deficiency increases anemia manifests. The cognitive scores were lowest in the iron deficient anemic (group I). In iron deficient without anemia it was slightly more than group I but much less than group III, that is, nonanemic noniron deficient subjects. Prevalence of anemia was 63% while prevalence of iron deficiency anemia in present study was 50%.There is need to initiate programme for supplementation of iron and folic acid to school going adolescent girls for the prevention of hematological and nonhematological consequences of iron deficiency with government and private organizational efforts."} +{"text": "To the Editor: Approximately 3,000 cases of tickborne encephalitis virus (TBEV) disease are registered annually in Europe , aseptic meningitis (3 cases), encephalitis (2 cases), meningoencephalitis (8 cases), and meningoencephalomyelitis (3 cases) (,During the past 20 years, TBEV has reemerged in several European areas that had been disease free (The implementation of a regional active surveillance system allows the highest sensitivity in assessing the epidemiologic features of TBEV infections, which are characterized by highly disease-endemic microfoci in areas free of the problem ("} +{"text": "Down syndrome includes learning and memory deficits in all cases, as well as many other features which vary in penetrance and expressivity in different people.

Recently, with new insights gained from studying mouse models of Down syndrome, specific genes and pathways are being shown to be involved in the pathogenesis of the disorder. This is opening the way for exciting new studies of potential therapeutics for aspects of Down syndrome, particularly the learning and memory deficits.Chromosome copy number aberrations, anueploidies, are common in the human population but generally lethal.

Extracts of Boswellia serrata have been clinically studied for the treatment of many inflammatory conditions such as osteoarthritis and rheumatoid arthritis (3). The resin from Boswellia Serrata contains a number of biological actives called pentacyclic triterpene acids, which give the extract its anti-inflammatory and analgesic properties, with boswellic acid the major active ingredient (4). These acids have been demonstrated to interfere with the body\u2019s natural inflammatory response by inhibiting cytokines and leukocyte activity. The present study aims to evaluate the long-term efficacy of Boswellia Serrata on headaches and disturbed sleep in patients with CCH.In an open-label study, 4 patients with CCH and disturbed sleep received oral Boswellia Serrata.The effects were long-lasting in 3 patients (mean 15 months) and transient (6 months) in one patient. The rapid improvement of nocturnal pain within weeks is similar to the analgetic effect observed in recent trials using Boswellia Serrata in cancer pain The mechanisms of how Boswellia Serrata reduces pain in CCH remain unclear. Boswellic acids, constituents of Boswellia extract have subsequently been identified as selective redox independent noncompetitive inhibitors of both 5-lipoxygenase, the key enzyme in leukotriene biosynthesis and human leukocyte elastase.

Overfilling of the balloon resulted in larger errors only in two catheters. Compliance estimations resulted in errors below 1 ml/ cmH2O. Superimposed pressure had no relevant effect on compliance estimation.During the initial inflation most catheters showed pressure artifacts resulting from material adhesion. Those artifacts disappeared during following inflations. Static pressure measurements could be performed with an error below 1 cmHThe reliability of pressure measurements and also of compliance estimation via the tested catheters is high. Only in two catheters was the filling volume a critical point for a precise measurement of pressure or for estimation of compliance. Immediately after unpacking, adhesion of the balloon material might prevent reliable pressure measurement, therefore before the first measurement overfilling of the balloon and retention of the excess gas seems strongly recommended."} +{"text": "Evaluate the effect of myocardial scar burden, scar location, and scar transmurality on response to cardiac resynchronization therapy (CRT)not respond to cardiac resynchronization therapy (CRT).

We theoretically demonstrate that extending the duration between the resection and the first BCG instillation negatively influences treatment outcome. Simulations of higher BCG doses and longer indwelling times both improved the probability of tumor extinction. A remarkable finding was that an inter-instillation interval two times longer than the seven-day interval used in the current standard of care would substantially improve treatment outcome. We provide insight into relevant clinical questions using a novel mathematical model of BCG immunotherapy. Our model predicts an altered regimen that may decrease side effects of treatment while improving response to therapy.Intravesical Bacillus Calmette Gu\u00e9rin (BCG) immunotherapy is considered the standard of care for treatment of non-muscle invasive bladder cancer; however the treatment parameters were established empirically. In order to evaluate potential optimization of clinical parameters of BCG induction therapy, we constructed and queried a new mathematical model. Specifically, we assessed the impact of (1) duration between resection and the first instillation; (2) BCG dose; (3) indwelling time; and (4) treatment interval of induction therapy \u2013 using cure rate as the primary endpoint. Based on available clinical and Adjuvant treatment of non-muscle invasive bladder cancer (NMIBC) using intravesical Bacillus Calmette-Gu\u00e9rin (BCG) after transurethral resection was established empirically almost 40 years ago in vitro experimental data to construct and parameterize a new stochastic mathematical model describing the interactions between BCG, the immune system, and tumor cells with the primary endpoint being the probability of tumor extinction. We did not aim for precise quantitative results but rather for a robust qualitative understanding that would remain valid for future models that could integrate increasing levels of detail. Herein, we assessed the impact of: (1) varying the time from resection to BCG instillation, (2) modulating the BCG dose used during intravesical instillation, (3) the indwelling time of BCG, and (4) the inter-instillation interval.Using a refined mathematical model that includes the adaptive effector functions of the immune system, we address several clinical parameters in order to learn about their impact for an optimal protocol of successful BCG immunotherapy. Specifically, we integrated available clinical and Although all parameters influenced treatment outcome, the most surprising result concerned the impact of the inter-instillation interval where simulations suggested that an interval two times longer than the seven-day interval used in the current standard of care, would substantially improve treatment outcome. Our study provides useful insight and testable hypotheses that could lead to improved management in NMIBC.Our mathematical model makes assumptions about the interactions triggered by BCG instillations and simulates the dynamics of populations of cells. Prior to initiation of BCG therapy, three cell populations are present: healthy urothelial tissue, tumor and innate immune cells. The interactions between these cell populations are negligible. The processes that take place for each of these cell populations before therapy are cell migration and/or local proliferation and death varying the time from resection to BCG instillation, (2) modulating the BCG dose used during intravesical instillation, (3) the indwelling time of BCG, and (4) the inter-instillation interval. Each probability of tumor extinction was calculated by running 1,000 stochastic simulations, such that it's resulting 95% confidence interval became reasonably small. The computer code was also employed in uncertainty and sensitivity analyses for assessing the robustness of our results .

But how do you know which animals are carrying disease? Sometimes they appear perfectly healthy. A study of 57 apparently healthy show pigs at a 2009 US state fair found that almost 20% were carrying influenza virus and at least 4 were carrying the 2009 pandemic virus. Of concern is the possibility that different types of influenza virus\u2014pandemic, swine, avian\u2014could combine in pigs and emerge as new viruses that then spread to humans. Swine workers, veterinarians, and other persons with pig contact may be at high risk for infection with pig influenza and should receive seasonal influenza vaccines, use personal protective equipment when working with healthy pigs, and limit their contact with sick pigs. Regular monitoring of influenza virus among pigs and testing of sick persons who have been exposed to pigs are needed. Within 5 months after the earliest detection of human influenza A(H1N1)pdm09 virus, we found molecular and culture evidence of the virus in healthy US show pigs. The mixing of humans and pigs at swine shows possibly could further the geographic and cross-species spread of influenza A viruses. Cross-species infections with influenza A viruses readily occur between humans and pigs. Pigs often have been infected by human epidemic viruses and South Dakota (2009). Exhibitors were eligible for the study if they reported working with pigs at least 1 cumulative hour per week and had no current immunocompromising condition. Enrolled participants completed a questionnaire and permitted collection of nasal swab specimens from their show pigs. Before data were collected, multiple institutional review boards, the Institutional Animal Care and Use Committee of the University of Minnesota and the University of Iowa, and state fair officials approved the study.After acquiring informed consent, we recruited persons t) values <35 were considered positive for influenza Avirus; specimens with Ct values of 35 to <40 were suspected to be positive; and specimens with Ct values >40 were considered negative. In a blinded fashion, aliquots of swab specimens from pigs were shared with the Minnesota Veterinary Diagnostic Laboratory , where rRT-PCRs for matrix, hemagglutinin (HA), and neuraminidase (NA) genes were performed. Specimens were then shared with the National Veterinary Services Laboratory and later with CDC for further molecular and sequencing studies.We used the Centers for Disease Control and Prevention real-time reverse transcription PCR (rRT-PCR) (http://blast.ncbi.nlm.nih.gov).Positive and suspected-positive rRT-PCR specimens were cultured in shell vials on MDCK cells by using standard techniques. Sequence-based analyses of the influenza A virus isolates were performed by the CDC influenza division, using full or partial genome sequencing approaches for all 8 gene segments. Sequences were compared by using BLASTn alignment search techniques (<1 year of pig exposure (Questionnaires were completed by 121 (98%) participants. Participants were predominantly male (71%), and their median age was 34.9 years (range 9\u201375 years); 24% of participants were <18 years of age. Some pig exhibitors were children with exposure ; others Nasal swab specimens were collected from a total of 149 pigs . Almost all (97%) swabbed pigs were <1 year of age, and 40% were female. All pigs were observed to be healthy by a veterinarian before they were permitted to enter the show.In 2008, nasal swab specimens from show pigs showed no molecular or viral culture evidence of influenza A virus. However, in 2009, a number of pigs were positive for influenza A virus. Comparing the molecular results of the 3 laboratories and using conservative rRT-PCR result interpretations on which all laboratories agreed, we determined that influenza A virus was detected in 12 (12%) of 102 swine respiratory samples by rRT-PCR; 11 (19%) of these were from among the 57 pigs swabbed at the Minnesota state fair . Viral cA follow-up telephone survey of study participants identified 2 with influenza-like illness (ILI) within 7 days after the fair: an adult, with ILI with onset 1 day after his pigs arrived at the fair (and 4 days before pig swabbing), and his daughter who developed an ILI on the last day of the fair (3 days after pig swabbing). Three pigs exhibited by the child tested positive for influenza A virus.We found a 19% prevalence of influenza A virus among the 57 show pigs swabbed at the 2009 Minnesota state fair, which occurred during the second wave of the 2009 pandemic. Temporal analysis of the results indicated that most pigs with rRT-PCR\u2013positive results were sampled within 24 hours after arriving at the fair, suggesting that they probably were infected before their arrival . None ofThese detections of A(H1N1)pdm09 virus in the United States (reflecting the ease of transmission from humans to pigs) were soon followed by multiple other detections in US pigs (Of concern is that new reassortants between A(H1N1)pdm09, enzootic SIVs, and possibly other human- or avian-origin viruses might emerge and possibly spread to humans who have contact with asymptomatic pigs (Because of the possibility of novel virus generation in pigs and of human-to-pig and pig-to-human transmission of influenza virus, routine influenza A virus surveillance among pigs and influenza A virus testing of ill persons exposed to pigs is needed to ensure timely detection of novel influenza viruses in humans and pigs ("} +{"text": "Porphyromonas gingivalis include phosphoethanolamine (PE DHC) and phosphoglycerol dihydroceramides (PG DHC) lipids. These PDHC lipids mediate cellular effects through Toll-like receptor 2 (TLR2) including promotion of IL-6 secretion from dendritic cells and inhibition of osteoblast differentiation and function in vitro and in vivo. The PE DHC lipids also enhance (TLR2)-dependent murine experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis. The unique non-mammalian structures of these lipids allows for their specific quantification in bacteria and human tissues using multiple reaction monitoring (MRM)-mass spectrometry (MS). Synthesis of these lipids by other common human bacteria and the presence of these lipids in human tissues have not yet been determined. We now report that synthesis of these lipids can be attributed to a small number of intestinal and oral organisms within the Bacteroides, Parabacteroides, Prevotella, Tannerella and Porphyromonas genera. Additionally, the PDHCs are not only present in gingival tissues, but are also present in human blood, vasculature tissues and brain. Finally, the distribution of these TLR2-activating lipids in human tissues varies with both the tissue site and disease status of the tissue suggesting a role for PDHCs in human disease.Novel phosphorylated dihydroceramide (PDHC) lipids produced by the periodontal pathogen Porphyromonas gingivalis is a periodontal pathogen strongly associated with development of destructive periodontal disease in adults. We have recently characterized the structures of novel phosphorylated dihydroceramide (PDHC) lipids produced by this organism P. gingivalis. Little is known regarding the capacity of other common human bacteria to produce these lipids and most importantly, whether these lipids can be identified in human tissues distant from sites normally colonized by these bacteria. Therefore, the purpose of this investigation was to evaluate intestinal bacterial species as well as other periodontal organisms for their capacity to produce PDHCs and to examine blood and human tissue samples for the presence of these novel TLR2-activating bacterial lipids.Bacteroides, Parabacteroides or Prevotella genera produced PDHCs and of these, most produced predominantly PE DHC lipids , whereas the remaining intestinal and oral bacteria produced negligible amounts of UnPG DHC lipids (PG DHC lipids (both the HM and LM forms) can exist with three aliphatic chains (the substituted or \u201cSub\u201d form) or can be de-esterified to a lipid class with 2 aliphatic chains (the unsubstituted or \u201cUn\u201d form) C lipids .In contrast, human tissue samples revealed significant percentages of both LM or HM UnPG DHC lipids . We nextOf note, the average total ion abundances of PDHC lipids per microgram of total lipid extract were at least 33 times higher in the control artery segments than the atheroma segments sites. We also evaluated blood plasma samples taken from periodontally healthy subjects or subjects with destructive periodontal disease. Two-factor ANOVA revealed significantly lower percentages of HM and LM SubPG DHC lipids and significantly higher percentages of HM and LM PE DHC lipids in periodontitis gingival tissue samples versus healthy samples . SimilarFor quantification of absolute PDHC lipid levels in control and periodontitis gingival tissue samples, each tissue lipid extract was supplemented with 1.5 \u00b5g of synthetic phospholipid internal standard before analysis by MRM/MS. This analysis revealed that lipid extracts of periodontitis tissue samples contained significantly higher mean levels of HM PE DHC and LM PE DHC lipids than that recovered in healthy gingival tissue samples until the time of lipid extraction. Human brain specimens were obtained as postmortem samples from the Colorado Brain Bank, Denver, CO.Porphyromonas gingivalis , Tannerella forsythia (generously provided by Dr. Sigmund Socransky) and Prevotella intermedia were grown in broth culture and after pelleting bacteria by centrifugation, the bacterial pellets were stored frozen until processing. At the time of lipid extraction, samples of bacterial pellets were removed and extracted using the same phospholipid extraction procedure.Intestinal bacterial samples that were previously stored frozen were grown on blood agar plates after demonstrating purity of bacterial isolates. The plates were scraped to recover the bacterial colonies and were extracted using the phospholipid extraction procedure of Bligh and Dyer All tissue and blood samples were stored frozen until processing. Gingival tissue, atheroma and brain samples were thawed and at least 20 mg of tissue was minced and extracted for several days in organic solvent according the method of Bligh and Dyer Individual lipid samples were analyzed using a QTrap 4000 mass spectrometer (ABSciex). A standard volume of each lipid sample (5 \u00b5l) was analyzed by flow injection and HPLC solvent was run at a rate of 80 \u00b5l/min. Using previously purified lipid preparations of each phosphorylated dihydroceramide class, the instrument parameters were optimized for detection of each lipid component based on gas phase transitions depicted in Each lipid ion transition peak was electronically integrated and the percentage abundance of each lipid class was calculated from the integrated lipid ion transition peaks. For each category of tissue or blood samples, all samples within a particular tissue or blood category were analyzed during a single analysis session.

Small RNAs were analysed from leaf and stolon tissues. 28 conserved miRNA families were found and potato-specific miRNAs were identified and validated by RNA gel blot hybridization. The size, origin and predicted targets of conserved and potato specific miRNAs are described. The large number of miRNAs and complex population of small RNAs in potato suggest important roles for these non-coding RNAs in diverse physiological and metabolic pathways.Micro RNAs (miRNAs) represent a class of short, non-coding, endogenous RNAs which play important roles in post-transcriptional regulation of gene expression. While the diverse functions of miRNAs in model plants have been well studied, the impact of miRNAs in crop plant biology is poorly understood. Here we used high-throughput sequencing and bioinformatics analysis to analyze miRNAs in the tuber bearing crop potato ( The recent discovery of small RNAs and their widespread roles in post-transcriptional gene regulation has changed our basic understanding of how genes are regulated during development and in different biological processes. These RNAs represent an additional layer in regulation of gene expression. The pathways and key enzyme components are well described and are highly conserved in plants and animals Increasing evidence shows that miRNAs play important roles in developmental processes and gene regulation upon biotic and abiotic stresses http://www.fao.org). Moreover, potato is being grown more extensively in developing countries with rapidly growing populations, such as those in South East Asia, so it is playing an increasing role in addressing food security issues. It is extremely important to understand the as yet poorly known molecular events in tuber development, which ultimately impact on the breeding of cultivars with improved tuber characteristics . There is a great deal of current interest and research in the molecular signals which promote tuberization in potato Potato is an important global food crop which is cultivated for its underground storage stems (tubers), rich in starch and nutrients and is unique among the major crops in tuber formation. The importance of potato globally is shown by the \u223c330 million tons production in 2010 (Solanum tuberosum group Andigena (clone ADG573) was used for small RNA library preparation and next generation sequencing. This clone was developed at The James Hutton Institute from the Commonwealth Potato Collection . ADG573 has the feature of being able to tuberize under short days (SD) but not under long days (LD), which is typical of germplasm originating from the Andes in South America. From 12 libraries of leaf and stolon materials using LD and SD conditions with three biological replicates about 60 million raw reads were obtained and further analysed. Firstly reads were quality filtered, adaptors were removed and ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), small nuclear RNAs (snRNAs) and small nucleolar RNAs (snoRNAs) were filtered out from the database . These miRNAs have relatively high read numbers in our database and each originates from one locus in the genome.

PotatoMir1005047020 showed similar expression pattern in different tissues in all the plants but PotatoMir1005907528 had lower levels in roots and higher in stolons. PotatoMir1005564753 had strong expression in every tissue in the different plants. These analyses strongly suggest that the examined miRNAs exist in plants and have high expression levels in several potato tissues.To validate the presence of these miRNAs in plant tissues RNA gel blot hybridization was performed. All the examined miRNAs are highly expressed in the examined tissues . We haveWith the aim to better understand the biological role of conserved and potato specific miRNAs we searched for putative target genes by using a plant small RNA target analysis tool: psRNATarget RAP1 (Relative to APETALA2 1) RAP1) was found for all the miR172 family members as a predicted target with low expectation score and unpaired energy suggesting it to be a highly likely target. Additionally, the NL25 protein disease resistance gene transcript (PGSC0003DMT400006234) is targeted by miR482b which is present in our prediction To prove the power of our prediction we searched among the predicted targets of miR172 for the known target miRNAs play key roles in most biological processes in animals and plants The small RNA analysis of potato showed that the 24 nt length class dominates in the dataset in total number and unique sequences strongly suggesting that small RNA directed heterochromatin silencing plays an important role in this crop similar to other species Most predicted miRNAs are of 21 and 24 nt in length. 21 nt miRNAs have the canonical size for small RNAs derived from DCL1 processing but a little variation in size might originate from the inaccuracy of DCL1 processing The prediction of miRNAs in our study, in contrast with previous reports, is based on results from high-throughput small RNA sequencing. Zhang et al. (2009) predicted 21 miRNA families but our study predicted 14 additional conserved miRNA families in potato. For 6 families we have predicted more members in the same family but our high-throughput study could not confirm the prediction for 9 of the reported miRNA families. Similarly, twelve miRNA families were found in common with another study Potential targets with a wide variety of predicted functions were identified for the miRNAs in potato: transcription factors, genes with a role in defence mechanisms, kinases and ion homeostasis genes. We have predicted the mRNA/gene targets of many potato miRNAs. Some have known functions in flowering and tuberization (miR172) or guiding cleavage of transcripts of immune receptors (miR482) Solanaceae species.In summary, we have identified conserved and potato specific miRNAs and their targets for the first time at a genome-wide level.

For sequences see For RNA gel blot hybridization of miRNAs total RNA was separated by 15% polyacrylamide (19:1) gel with 8M urea and 1 \u00d7 MOPS buffer. RNA markers were end labelled by http://code.google.com/p/cutadapt/). First, low-quality ends were trimmed by applying a quality score threshold of 20. In the applied trimming method, the threshold is subtracted from all quality scores and partial sums from all indices to the end of the sequence are then computed. Sequences are cut at the indices where the sums are minimal. Adaptors were then removed by matching the first (for 3\u2032 adaptors) and last (for 5\u2032 adaptors) 8 nt of the adaptor sequences while allowing 1 nt of mismatch maximum.Quality trimming and adaptor removal of the Illumina reads were carried out using Cutadapt (http://www.phrap.org/phredphrapconsed.html). The sequences aligned to the above databases with at least 10 matched nts and a minimum alignment score of 10 were excluded from further analysis. Sequences, shorter than 17nt and longer than 35 were also discarded.Sequences were then searched against ribosomal, transfer RNAs, snRNAs and snoRNAs from Rfam, the Arabidopsis tRNA databases and plant rRNA and tRNA sequences from EMBL using cross_match (http://potatogenomics.plantbiology.msu.edu/index.html) on all of the plausible positions using Bowtie with perfect matches (0 mismatches). Then the sequences that were mapped to multiple positions in the genome were filtered based on the maximum size of potato miRNA families. The threshold was set at 30 to recover small RNAs with relatively large family sizes. 4,006,195 flanking regions of the 3,113,450 filtered sequences were retrieved from the genome using a window of 250 bps.

This hook protects the apical meristem from mechanical damage during seedling emergence from the soil. In darkness, gibberellins act via the DELLA-PIF (PHYTOCHROME INTERACTING FACTORs) pathway, and ethylene acts via the EIN3/EIL1 (ETHYLENE INSENSITIVE 3/EIN3 like 1)-HLS1 (HOOKLESS 1) pathway to control the asymmetric accumulation of auxin required for apical hook formation and maintenance. These core pathways form a network with multiple points of connection. Light perception by phytochromes and cryptochromes reduces the activity of PIFs and (COP1) CONSTITUTIVE PHOTOMORPHOGENIC 1\u2014both required for hook formation in darkness\u2014, lowers the levels of gibberellins, and triggers hook opening as a component of the switch between heterotrophic and photoautotrophic development.

Light exposure initiates the transition between skoto- to photomorphogenesis is perceived mainly by phyA, phyB and cry1. phyA is important for the early steps of this transition, which is completed by phyA itself under dense canopies and by phyB and cry1 in open places to the active (Pfr) form and part of these Pfr pools migrate to the nucleus in Figure A. thaliana seedlings grown in darkness, the formation phase lasts approximately 26 h after germination while the maintenance phase, where the hypocotyl remains closed, lasts another 25 h and the concave (inner) and convex (outer) sides across the hook or 1-naphthoxyacetic acid (1-NOA) reduces hook formation and GH3 (GRETCHEN HAGEN 3) gene families and AUX/IAA (AUXIN/INDOL-3-ACETIC ACID) proteins gene encodes a N-acetyltransferase that is required for apical hook formation. The hls1 mutant fails to form the apical hook due to defects in both differential cell elongation and cell division and PIF4 see Box , interfeSo, gibberellins are crucial for apical hook formation. Gibberellins are needed to maintain DELLA levels reduced and thus PIF and EIN3/EIL1 transcription factors are available to increase WAG2 and HLS1 which regulate asymmetric auxin accumulation.ethylene overproducer mutants confer ethylene insensitivity and lack of an apical hook, while loss-of-function mutations cause hypersensitivity to ethylene and exaggerated hooks after ethylene treatment , ERS1, ERS2 (ETHYLENE RESPONSE SENSOR 1 AND 2) and EIN4 (ETHYLENE INSENSITIVE 4) receptors , the enzyme that catalyzes the first limiting step in tryptophan synthesis are higher in the inner than in the outer side lack an apical hook in darkness reporter gene which is involved in brassinolide synthesis, shows induced expression of the reporter gene by ethylene in apical hooks. Also, dark-grown det2 mutant seedlings treated with exogenous ethylene are not able to induce an exaggerated hook suggesting ethylene action requires brassinosteroids that is deficient in the perception of brassinosteroids but have activated downstream brassinosteroids responses due to a dominant mutation that stabilizes BZR1, forms and apical hook similar to that of the WT that phosphorylates ARF2 and reduces its activity, leading to the enhanced expression of auxin responsive genes and phyB . Since BBX23 is a repressor of photomorphogenesis required for hook maintenance in darkness, down-regulation of its expression enhances hook opening , which attenuates late hook opening possibly as part of a mechanism that avoids an exaggerated response of hook opening to light stimulus once seedlings are de-etiolated show impaired hook opening under far-red light, but hfr1 (long hypocotyl in far-red) and laf1 (long after far-red light) mutants are affected in hypocotyl elongation but not in hook opening under far-red light see Box .

PIFs operate downstream of gibberellins and affect auxin transport and ethylene synthesis. EIN3/EIL1 are indirect targets of light signaling, through the PIFs and DELLA pathways, operate downstream gibberellins and ethylene and affect auxin transport, synthesis and signaling. The connections between COP1 and the hormonal network that underlies the formation of the hook in darkness are not firmly established.The coordinated actions of gibberellins, ethylene and brassinosteroids control asymmetric auxin distribution to allow the correct development of the hook in darkness. This control occurs at multiple levels, including synthesis, distribution by the action of specific transporters and abundance of transcription factors involved in the control of auxin-responsive genes. PIFs and EIN3/EIL1 are key connectors of gibberellins and ethylene pathways with auxin signaling in the hooks. The repressors of photomorphogenesis PIFs and COP1 are indispensable for hook development in darkness and the activation of phytochromes and cryptochromes by light negatively regulates the activity of PIFs and COP1, leading to the opening of the hook.Considerable progress has been made in recent years in the elucidation of the signaling network that controls apical hook formation in darkness; however there still are several gaps concerning how light-regulated proteins modulate hook formation and triggers hook opening.

The MSN express dopamine receptors that are either positively (D1) or negatively (D2) coupled to adenylyl cyclase therefore dopamine directly influences intracellular levels of cAMP. Participants in cAMP mediated signalling pathways are often organized in multiprotein complexes around A-kinase anchoring proteins (AKAPs).

We also demonstrated the great potential of TEs and transposition in the generation of diverse phenotypes as well as in the natural amplification and dissemination of genetic information by horizontal gene transfer, which is considered the driving force of bacterial evolution.Several trap plasmids (enabling positive selection of transposition events) were used to identify a pool of functional transposable elements (TEs) residing in bacteria of the genus Transposable elements (TEs) are components of nearly all prokaryotic genomes. They are mobilized to change their location in DNA by the action of a transposase (TPase), an enzyme which catalyses transposition, i.e. recombination that does not require sequence homology between the TE and the target site. The presence and activity of TEs may lead to structural changes in both the size and composition of a genome. TEs can generate (i) various mutations, such as insertions, deletions, duplications, inversions and translocations of even large DNA fragments, and (ii) replicon fusions The simplest TEs are insertion sequences (ISs), which are highly abundant in bacteria. They carry only genetic information that is necessary and sufficient for transposition and its regulation. The majority of ISs are composed of a single open reading frame (ORF), encoding a transposase, flanked by two inverted repeat sequences (IRs) that are recognized by the TPase during transposition. In most cases, the transposition of ISs causes duplication of the target site, so that the inserted element is bordered by two short (2\u201315 bp) identical direct repeat sequences (DRs) Bacillus cereusISs are also able to form more complex TEs such as (i) composite transposons consisting of random segments of genomic DNA (core region) bordered by a pair of ISs, or (ii) transposable modules (TMos) and ISCR elements composed of one IS copy, which can mobilize an adjacent DNA segment for transposition 3 and Tn7 families. Besides a transposase, the Tn3 elements contain a site-specific recombination module encoding a resolvase , while the Tn7 elements are known for their complex transposition machinery (they encode five transposition proteins) There is another widely distributed group of TEs called the non-composite transposons, which is divided into the TnLarge-scale genome sequencing projects have led to an explosion in the number of annotated prokaryotic and eukaryotic TEs . This genus currently comprises 31 species, which have been isolated from many geographical locations and from different environments. Paracoccus spp. are physiologically among the most versatile bacteria, and are able to perform a number of different growth modes. Many are aerobic chemoorganoheterotrophs utilizing a wide variety of organic compounds, including potential pollutants like acetone, N,N-dimethylformamide and methylamine Paracoccus spp. are facultative chemolithoautotrophs utilizing reduced sulfur compounds, molecular hydrogen and Fe(II) as energy sources In 2009 we initiated a project aimed at identifying functional transposable elements harbored by bacteria belonging to the genus Paracoccus spp., it is tempting to speculate that their physiological heterogeneity might result from various transposition events.Although there is no direct evidence linking the presence of TEs with important phenotypic traits of Paracoccus species were analyzed. For the identification of functional TEs we used trap plasmids, which are convenient tools enabling the direct identification of even phenotypically silent elements (reviewed by Solyga and Bartosik) P. pantotrophusP. solventivoransP. marcusiiP. methylutensPme2, ISPpa2, ISPpa3, ISPpa4, ISPso2, ISPso3 (IS5 family), ISPpa5 (IS66 family), ISPpa1, ISPso1 (IS256 family) and IS1247a, ISPme1 (IS1380 family), ISPmar4 (ISAs1 family) 3 family \u2013 cryptic Tn3434 and streptomycin resistant Tn5393Ppa1, whose transposition is mediated by two copies of Tn34341380-family element and adjacent fragments of genomic DNA of various lengths Paracoccus spp. strains. We also analyzed the structure, frequency of transposition, specific features and distribution of the captured TEs, which allowed us to draw more general conclusions concerning their evolutionary impact, as well as the direction and frequency of horizontal gene transfer in this group of bacteria.In this study, TEs residing in strains representing 20 r) derivatives of the wild-type strains of Paracoccus spp. (listed in Escherichia coli TG1 Paracoccus spp.) or 37\u00b0C (E. coli). P. homiensis DSM 17862 was cultivated in Marine Broth (Difco). Where necessary, the medium was supplemented with sucrose (10%) and with antibiotics at the following concentrations (\u00b5g\u00b7ml\u22121): kanamycin, 50; rifampicin, 50; tetracycline, 0.3\u201335 (depending on the strain).For identification of transposable elements rifampicin-resistant a silent tetracycline resistance gene tetA under the control of the bacteriophage lambda pR promoter, and (ii) the gene encoding the lambda cI repressor. Inactivation of the repressor gene (e.g. through insertion of an IS), results in constitutive expression of tetracycline resistance r version pEBB10, contains the sacB gene of Bacillus subtilis, coding for levan sucrase \u2013 an enzyme that catalyzes sucrose hydrolysis and levan extension. The products of this reaction are toxic for gram-negative bacteria. Therefore, cells carrying the functional sacB gene are sucrose sensitive (Sucs) and their cultivation in medium containing sucrose results in cell lysis sacB mutants (Sucr) (e.g. carrying inserted TEs), whose growth is not affected under these conditions, thus enabling positive selection of transposition mutants. The BHR trap plasmid pCM132TC, contains a promoterless tetracycline resistance gene tetA. In this case, the transposition of TEs containing strong promoters upstream of the tetA gene can initiate its expression, resulting in tetracycline resistance in cells carrying such mutated plasmids Ppa1 were (i) pBBR1MCS-3 oriV of pMAR4 of P. marcusii DSM 11574; oriT RK2; Kmr), (iii) pDIY703 oriV RA3; oriT of RK2; Kmr), (v) pMAO-MS oriV RA3; oriT of pIGRK of K. pneumoniae 287-w; Kmr) For the identification of TEs, the following trap plasmids were used: pMEC1 Paracoccus spp. strains by triparental mating as previously described E. coli cells was performed according to the method of Kushner DNA was introduced into Paracoccus spp. was isolated by the procedure described by Chen and Kuo Plasmid DNA was isolated using a standard alkaline lysis procedure r strains of Paracoccus spp. The overnight cultures of the transconjugants were spread on plates with solidified LB medium supplemented with tetracycline or sucrose (pMAT1 or pEBB10). Appropriate dilutions of the cultures were also spread on LB medium in order to determine the frequency of transposition. For each strain, the plasmids of at least 100 Tcr or Sucr clones were analyzed. Three classes of plasmids were distinguished carrying (i) potential insertion sequences (inserts <3 kb), (ii) putative transposons (inserts >3 kb) or (iii) point mutations (replicons of the same size as the trap plasmid). The insertion sites of the elements were localized by performing PCRs with the trap plasmid insertion derivatives (as template DNA) and previously described sets of cassette-specific primers Trap plasmids were introduced into the RifParacoccus ferrooxidans NCCB 1300066 digested with restriction endonucleases NcoI or XhoI. The digested DNA preparations, purified using a Clean Up kit (A&A Biotechnology), were then self-ligated overnight at 16\u00b0C with T4 DNA ligase (Fermentas). The ligation mixture was used as the template for amplification by PCR of the DNA flanking Tn6097 in the host genome. The synthetic oligonucleotides used in PCR were LIPCRPF2 and RIPCRPFE (Templates for inverse PCR (IPCR) were prepared from total DNA of RIPCRPFE .Dot blot analysis was performed using a Bio-Dot apparatus (Bio-Rad) according the manufacturer's instructions. To determine copy number of TEs in parental strains Southern blotting was carried out as described by Sambrook and Russell tetA gene in this vector) were analyzed to localize the TE-derived promoters. Deletion analysis was performed for two of the analyzed elements (Tn5393 and Tn6097), by removal of different parts of the inserted TE by digestion with appropriate restriction enzymes, followed by religation and characterization of the resistance phenotype. The constructed mutants contained different parts of the 3\u2032-end of the transposon, adjacent to the promoterless tetA gene. For the insertion sequences ISPam1, ISPkr1 and ISPaes3, PCR was applied to amplify (i) the terminal 3\u2032-end DNA fragments of the elements and (ii) analogous fragments with an attached short DNA region of the trap plasmid, adjacent to the target site of transposition (identification of possible hybrid promoters). The amplified DNA fragments were cloned into pCM132TC (Tcs) upstream of the promoterless tetA gene or into pCM132 upstream of promoter-less lacZ reporter gene. The presence of a promoter (tested in Paracoccus spp. hosts) resulted in a Tcr phenotype (pCM132TC) or expression of \u03b2-galactosidase (pCM132). \u03b2-galactosidase activity was measured as previously described A pool of derivatives of the trap plasmid pCM132TC (containing inserted TEs able to drive transcription of a promoterless http://www.ncbi.nlm.nih.gov/). G+C plots were created using the program Artemis 6097 and Tn6122 was assigned by the Tn Number Registry website according to the generally accepted nomenclature Nucleotide sequences of TEs were determined using a dye terminator sequencing kit and an automatic sequencer (ABI 377 Perkin Elmer). A combination of vector-derived primers and primer walking was used to obtain the entire nucleotide sequences. Similarity searches were performed using the ISfinder The nucleotide sequences of the elements identified in this study have been submitted to the ISfinder and GenBank databases. Accession numbers of the sequences are given in Paracoccus spp. we used mobilizable trap plasmids pMEC1, pMMB2, pMAT1, pEBB10 and pCM132TC carrying three types of cassette enabling positive selection of transposition events (see cI-tetA or sacB cassettes) enable the capture of all types of TEs, irrespective of their structure, specific features and genetic load. In contrast, pCM132TC only permits the identification of elements containing strong outwardly oriented promoters or those able to generate hybrid promoters, which drive the transcription of nearby genes.To identify functional TEs of ents see . The plaParacoccus spp. and pools of clones carrying mutated plasmids were obtained and analyzed as described in 3 family .The trap plasmids were introduced by conjugation into 25 strains of 3 family and 2. TThe nucleotide sequences of the captured ISs were subjected to detailed analysis. All contained a transposase gene(s) and terminally placed inverted repeat sequences (IRs). Moreover, all were able to generate DRs at the target site of transposition . Since tParacoccus spp. ISs identified in this study. Analogous analysis was also used to compare the nucleotide sequences of the terminal IRs of the ISs , which contain three conserved residues (two aspartate and one glutamate) constituting the DDE motif , that is highly conserved in the majority of bacterial TPases the ISs .1248f, ISPko1a, ISPpa3a, ISPpa5a and ISPve1a. In only four cases we found completely identical elements residing in different bacterial strains \u2013 ISPpa2, IS1247, IS1248 and ISPpa8. The identified ISs and their characteristics are presented in Preliminary analysis revealed that the vast majority (32) of the identified ISs were novel elements. In five cases, we captured ISs that were highly related to known elements \u2013 ISParacoccus spp. could be classified into the following families: (i) IS3 family (IS407 group) \u2013 4 captured elements, (ii) IS5 family \u2013 22 elements, (iii) IS6 family \u2013 2, (iv) IS21 family \u2013 3, (v) IS66 family \u2013 2, (vi) IS256 family \u2013 1, (vii) IS1182 family \u2013 1, (viii) IS1380 family \u2013 1, and (ix) IS1634 family \u2013 1.Based on the results of these comparative analyses, the ISs of 407 group of the IS3 family and IS427 group of the IS5 family) carry two overlapping ORFs and possess a conserved frameshift motif (1 of E. coli) 1 and IS3 families As shown in ft motif , which i427 group of the IS5 family is a natural point mutant, because, in contrast to other elements of this group, it carries a single large ORF encoding a functional DDE transposase.Interestingly, we found that one of the members of the IS21 and IS66 families besides the transposase gene(s). In most cases, the specific role of the predicted proteins encoded by these ORFs is unknown, although it is highly probable that they are involved in the regulation of the process of transposition. Such multi-ORF structures are typical for members of the ISfamilies .427 group of the IS5 family (8 ISs) contain, within their left IR , a sequence partially matching the consensus sequence of the integration host factor (IHF) binding site (5\u2032- WATCAANNNNTTR -3\u2032) 10427 group.We also performed a detailed inspection of the nucleotide sequences of the captured ISs in order to predict any DNA sequences that may constitute a site of interaction with host-encoded factors. This analysis revealed that the majority of the elements of the IS6097 , which was captured in P. ferrooxidans NCCB 1300066 using the trap plasmid pCM132TC. A summary of the predicted ORFs of Tn6097, including their position, the size of the encoded proteins, and their closest homologs is presented in The only composite transposon identified in this study was a novel element, designated Tn6097 into the selective cassette of pCM132TC generated 6-bp DRs. This transposon contains two identical, convergently oriented copies of ISPfe2 (1884 bp), that are responsible for its mobility (Betaproteobacteria), share 51% aa sequence identity.Transposition of Tnmobility . Using tPfe2 flank the large core region of Tn6097, comprised of 13,991 bp. The average G+C content of this region is 63.6 mol%, which is lower than that of the total DNA of the native host P. ferrooxidans NCCB 1300066 (67 mol%). The core region contains 12 ORFs whose putative products show similarity to proteins conserved in many bacteria, including some involved in the metabolism of nitrogen compounds and resistance to chemotherapeutics. Based on the predicted functions of the ORFs, they may be divided into three clusters, which can also be differentiated by the G+C content of their nucleotide sequences (data not shown).The two copies of ISP. pantotrophus5-formyltetrahydrofolate and ATP into 5,10-methenyltetrahydrofolate, ADP and phosphate, which results in the creation of carbon-nitrogen bonds due to the cyclo-ligase activity The first cluster contains four ORFs (ORF2-ORF5) encoding6097 contains four ORFs (ORF6-ORF9) arginine/ornithine antiporter (ArcD), (ii) arginine deiminase (ArcA), (iii) ornithine carbamoyltransferase (ArcB) and (iv) carbamate kinase (ArcC), respectively. The arcABCD operon of Tn6097 exhibit the highest nucleotide sequence similarity (76%) and synteny to homologous genes in plasmid pOANT03 of Ochrobactrum anthropi ATCC 49188 (accession no. NC_009671).The second cluster of TnF6-ORF9) with sig6097 consists of three ORFs (ORF10-ORF12) adjacent to the right-hand copy of ISPfe2, which encodes a putative NAD-dependent epimerase/dehydratase that is most similar (85% aa identity) to a protein of P. denitrificans PD1222 (The third putative genetic module of Tn0-ORF12) encodings PD1222 .6097 is present in one copy in the P. ferrooxidans NCCB 1300066 genome (data not shown). Using inverse PCR (IPCR) we determined the nucleotide sequence of its original target site in the host genome (see 6097 is located within a gene (disrupted upon transposition), whose predicted product shows similarity to a number of bacterial proteases. The highest identity (67%) was observed with a htpX gene of Polymorphum gilvum SL003B-26A1 (accession no YP_004302375). The transposon was flanked by 6-bp long DRs (5\u2032-GGCTCG-3\u2032), confirming that it had been incorporated into the host genome by means of transposition.DNA hybridization analysis revealed that Tn3 family of transposons. Two of the identified transposons (Tn6122 and Tn3434a) were identified as cryptic elements, solely encoding genetic information required for transposition was the presence of two putative genetic modules (responsible for transposition and resolution of cointegrates resulting from replicative transposition), which are highly conserved in members of the Tnposition .6122 (3792 bp) was captured in P. halophilus JCM 14014 using the trap plasmid pMEC1. This element is composed of (i) identical 39-bp IRs, (ii\u2013iii) two divergently oriented ORFs encoding a large transposase protein and a resolvase (TnpR) as well as (iv) an AT-rich putative recombination site (res) separating the ORFs (this region is involved in cointegrate resolution and regulation of expression of the tnpA and tnpR genes) Alphaproteobacteria: (i) Sulfitobacter sp. NAS-14.1, (ii) Ruegeria sp. PR1b and (iii) Roseovarius sp. TM1035. These transposons encode highly related transposases and resolvases, and are bordered by IRs identical to those of Tn6122 (data not shown).Tn3434a (3695 bp), identified using pEBB10 in P. aminophilus JCM 7686, is an isoform of the transposon Tn3434, that we trapped previously in P. pantotrophus DSM 11072 3434 (36 mismatches). The resolvases encoded by these elements are 100% identical, while their transposases differ in 30 aa (data not shown).The second trapped cryptic transposon, Tn3434a is also related to Tn6122. As shown in TnP. pantotrophus LMD 82.5 contains a non-composite transposon Tn5393, which is another member of the Tn3 family 3434a and Tn6122, carries two streptomycin resistance genes (strA and strB) placed downstream of the tnpR gene and their sequence identity is only 50% (14 mismatches). In contrast, the IRs of Tn5393 are much longer (81 bp with 4 mismatches between IRL and IRR), but their termini show significant similarity to those of Tn3434a, Tn6122 and other members of the Tn3 family , which was previously identified in this strain During analysis carried out in Analyses performed using trap plasmids not only enabled the capture of many functional TEs but also identified specific features of several elements, including their ability to (i) activate transcriptionally silent genes, (ii) generate deletions within the target sites of transposition and (iii) transpose at unusually high frequency.903 group of the IS5 family (ISPam1 and ISPpa8), (ii) the IS407 group of the IS3 family (ISPam3 and ISPfe1), (iii) the IS21 family and (iv) the IS256 family (ISPaes3). We also captured two transposons: (i) Tn5393 of the Tn3 family and (ii) the novel composite transposon Tn6097 bordered by two copies of ISPfe2 (IS1634 family).Using the trap plasmid pCM132TC (contains a promoterless tetracycline resistance gene as the selection cassette) we identified several TEs that are able to drive the transcription of promoterless genes placed downstream of the target site of transposition. The majority of the elements identified in this way were insertion sequences from four different groups: (i) the ISr clones, as described in 5 (IS903 group), IS3 (IS407 group) and IS21 families (256 member) (5393 of the Tn3 family) a member) , (iii) t family) , or (iv)y) which naturally occurs in strain DSM 11073.An unexpected phenomenon was observed upon selection of TctetA gene). The inserted trap plasmid was bordered by two copies of the insertion sequence IS1248 (IS427 group of the IS5 family), which strongly suggests that co-integrates were generated upon replicative transposition of this IS the appearance of a DNA band corresponding to the resolved trap plasmid. In contrast, we were never able to detect individual replicons when plasmid DNA was isolated from bacteria grown in medium supplemented with tetracycline, which strongly suggests that this antibiotic provides selection for the maintenance of the co-integrates.1248. When introduced into the strain DSM 11073, this plasmid (pCM132TC::IS1248), did not confer the Tcr phenotype, which precludes the possibility that a promoter of the IS may drive transcription of a nearby gene.DNA sequencing of the selection cassette of the resolved trap plasmid confirmed the presence of an inserted copy of IStetA gene in the co-integrate is driven by a promoter located within pKLW1. This conclusion is supported by the DNA sequence of regions flanking the original insertion site of IS1248 within pKLW1 and the detection of activity of the upstream promoter (These observations indicate that expression of the promoter .Pmar2 of P. marcusii DSM 11574 and ISPve1 of P. versutus UW400) into selection cassettes could be accompanied by deletions at the transposition target site.The transposition of the vast majority of TEs identified in this study resulted in the simple insertion of the elements into the trap plasmids and the generation of DRs. However, we found that the insertion of two ISs (ISPmar2 (IS407 group of the IS3 family) we identified only one deletion mutant . The deletion (15 bp) occurred at the 3\u2032-end of the inserted IS, and therefore the intact element was not bordered by the DRs, in contrast to the other clones tested.In the case of ISPve1 (IS21 family), which frequently generated much larger deletions within the selection cassettes of various trap plasmids. Initial analysis of a pool of Tcr clones of strain UW400 (obtained with pMEC1) revealed the presence of two types of pMEC1 mutants representing either (i) simple insertion of ISPve1 (7% of Tcr clones), or (ii) insertion of ISPve1 associated with deletions within the trap plasmid (16%). The remaining Tcr clones did not contain any TEs.More interesting was the case of ISPve1 resulted in the generation of 8-bp long DRs. Moreover, in both the insertion and deletion mutants, the element was always placed in the same orientation within the cI gene of pMEC1 and in each case, the location of the replication system was the factor limiting the range of deletions generated within the plasmid was observed for ISPaes3 of P. aestuarii DSM 19484. In contrast, the element most dynamic in transposition was Tn5393 (P. pantotrophus LMD 82.5), which transposed into the selection cassette of the trap plasmid pCM132TC at a very high frequency (10\u22123). This is in agreement with our previous observations performed in the strain LMD 82.5 with pMEC1 In most cases, the frequency of transposition of the captured TEs ranged from 10rain see . The lowP. pantotrophus DSM 11072. Surprisingly, in this case, the vast majority of the transconjugants (92%) did not contain pMEC1 (9.4 kb) but they carried a very large replicon (>50 kb), that was not originally present in DSM 11072. The remaining transconjugants (8%) contained intact pMEC1. DNA hybridization followed by DNA sequencing revealed that the large nascent plasmids are in fact insertion mutants of pMEC1. They were generated by transposition into the trap plasmid of a large previously described composite transposon TnPpa1 3 family transposon Tn3434, which border the core region of the element containing a set of genes conserved in the chromosomes of many bacteria Ppa1 into pMEC1. Intriguingly, all the transposon insertions were detected in randomly tested Kmr transconjugants, i.e. without applying positive (tetracycline) selection for the identification of transposition events. DNA sequencing of several insertion derivatives of pMEC1 confirmed that transposition of TnPpa1 had targeted random parts of the trap plasmid. In each case the inserted element was bordered by DRs, of a length typical for other members of the Tn3 family (5 bp) (data not shown).TnPpa1 is able to transpose as frequently into other replicons. For this purpose, several mobilizable plasmids were transferred into strain DSM 11072R. The plasmids contained different replication systems derived from (A) three broad host range replicons \u2013 (i) RA3 , (ii) RK2 (pCM132TC) and (iii) pBBR1 , as well as from (B) three plasmids originating from Paracoccus spp. \u2013 (i) pMAR4 of P. marcusii DSM 11574 (pDG12), (ii) pAMI7 of P. aminophilus JCM 7686 (pDIY703) and (iii) pTAV1 of P. versutus UW1 (pMMB2).We also tested whether TnPpa1 into plasmids containing replication systems of pMAR4 and pAMI7 as well as into all derivatives of RA3 , but not into the other tested plasmids (data not shown). This strongly suggested that the observed transposition phenomenon is dependent on the nature of the incoming replicon.Analysis of the plasmid content of the obtained transconiugants revealed massive transposition of TnSouthern blotting and DNA hybridization analysis were performed to examine the copy number and genomic location (plasmid/chromosome) of the identified TEs in their natural hosts.Paracoccus spp., which most probably reflects the replicative transposition of some of these elements. As shown in 427 group of the IS5 family , (ii) the IS903 group of the IS5 family , (iii) the IS407 group of the IS3 family , and individual members of (iv) the IS21 family (ISPve1a) and (v) the IS66 family (ISPpa7). Some of the detected IS copies displayed different signal intensities in the hybridization analysis, which most probably reflects divergence in the nucleotide sequences of closely related elements or the presence of truncated copies of the same element (data not shown).The analysis revealed that most of the identified insertion sequences were present in multiple copies in 5 family , (ii) the IS6 family and (iii) the IS256 family (ISPaes3), as well as for the identified transposons .In contrast, a low copy number (1\u20132 copies) was observed for all members of (i) the IS5 group of the ISP. aminophilus JCM 7686, P. halophilus JCM 14014, P. kondratievae NCIMB 13773T, and P. marcusii OS22 that were available in 2009, when this project started. In total, we tested approximately 7000 individual clones to identify trap plasmid insertion derivatives. However, despite the complexity of this analysis, it is obvious that not all the TEs residing in Paracoccus spp. were defined; we only identified those that are the most dynamic in transposition, i.e. elements of highest evolutionary impact. As a result, we captured 41 elements representing (i) insertion sequences, (ii) an IS-driven composite transposon and (iii) non-composite transposons of the Tn3 family.The genus Paracoccus spp. As expected, the vast majority of the captured elements were insertion sequences. We identified 47 elements, representing 10 IS families: IS3, IS5, IS6, IS21, IS66, IS256, IS1182, IS1380, IS1634 and ISAs1. Interestingly we did not encounter elements of the IS1, IS4, IS91 or IS110 families, which are widely distributed among other bacteria In total, together with our previous studies Paracoccus spp. were members of the IS5 family (26 elements), while only single elements from the ISAs1, IS1182 and IS1634 families were captured. However, dot blot DNA hybridization revealed that TEs are much more abundant in Paracoccus spp. than we had expected. These results suggest that each tested strain carries elements belonging to several different families .Southern blotting and DNA hybridization analysis revealed that most of the ISs identified in 6097 carries two putative conserved genetic modules. Specific functions of closely related modules have previously been determined in other bacterial hosts. One of the modules carries most probably genes involved resistance to daunorubicin and doxorubicin (used in the treatment of some types of cancer arcABC genes), which enable bacteria to grow anaerobically in the presence of arginine. The enzymes mediate the conversion of arginine to ornithine, NH3, and CO2, with the generation of ATP. It has been shown that this pathway constitutes a major source of energy for several microorganisms, e.g. strains of Mycoplasma spp., Pseudomonas spp. and Bacillus spp. TnP. ferrooxidans NCCB 1300066 (host strain of Tn6097) is unable to grow anaerobically in the presence of arginine (data not shown), which suggests that the arcABCD operon may be not functional. It has been previously demonstrated that anaerobic expression of the closely related operon of Pseudomonas aeruginosa, requires a transcriptional activator 6097. It is therefore possible that the ADI module of Tn6097 may be functional exclusively in the strains encoding a compatible transcription regulator.However, we have observed that 3 family, which represent different stages in the evolution of this group of transposons. It is believed that the Tn3 transposons originate from progenitor IS elements , which acquired an additional genetic module involved in site-specific resolution of cointegrates (intermediates of replicative transposition) as well as other genes whose products can directly affect the phenotype of their host We have also identified several non-composite TEs of the TnParacoccus spp. we identified two cryptic transposons (Tn6122 and Tn3434a) that contain the conserved module for site-specific recombination. We also captured the transposon Tn5393 (closely related to Tn3434a), which apart from the resolvase module, carries two additional streptomycin resistance genes of P. pantotrophus DSM 11072, which can be considered a composite transposon generated by two copies of the non-composite Tn3434Ppa1 provides evidence that the Tn3-family transposons (similarly to ISs) are able to mobilize large segments of genomic DNA for transposition. The generation of such composite elements seems to be very rare because of transposition immunity (a phenomenon that is thought to apply to members of the Tn3 family), which precludes transposition of more than one copy of the element into a single replicon Ppa1, composed of two identical copies of Tn3434, has a unique structure and, to our knowledge, is the only element of this type identified so far.The next step in the evolution of TnPpa1 is able to transpose into random sites of several mobilizable plasmids with unusually high frequency, not previously observed for any other bacterial TE. Our observations strongly suggest that the massive transposition of TnPpa1 might result from the specific features of the transferred plasmids. Irrespective of the precise mechanism of TnPpa1 transposition, it is clear that targeting of mobilizable or conjugal plasmids contributes to the dispersal of this element among bacterial populations. Within its core region, TnPpa1 carries a number of genes , whose presence may potentially improve the ecological fitness of the host cells Alphaproteobacteria In this study, we found that Tn\u22123) of another member of the Tn3 family: the streptomycin resistance Tn5393 (P. pantotrophus LMD 82.5) \u2013 far higher than that observed for other non-composite members of this family (3434 was 10\u22126) 5393 explains the wide dissemination of this transposon in many bacterial isolates In this study, we also observed very frequent transposition , and (ii) a transposon of the Tn3 family (the aforementioned Tn5393).We showed that activation of nearby genes is a typical feature of insertion sequences of the ISr phenotype (activation of the promoterless tetA gene of pCM132TC) were examined in detail. This analysis revealed that transposition-mediated delivery of promoters to transcriptionally silent genes can occur in at least five ways , which was prone to generate deletions within target DNA molecules . This indicates that transposition may significantly shape plasmid genomes and promote plasmid diversity, which could have significant evolutionary implications.Another interesting phenomenon observed in this study was connected with the insertion sequence ISolecules . The tra21 family identified in this study, including ISPve1a, an isoform of ISPve1 from P. bengalensis DSM 17099 (99% identity at the nucleotide sequence level). The high frequency of deletions generated by ISPve1 (in comparison with \u201cpure\u201d insertion events) might therefore be a specific feature of this element. Alternatively, it might result from the presence of host factors, which stimulate such deletions. The latter hypothesis is supported by data recently published by Kusumoto et al.Pve1 and the strain P. versutus UW400 are necessary to determine the likelihood of these two possibilities.Interestingly, this \u201cdeletion\u201d phenomenon was not observed for other members of the ISPme1Paracoccus spp. It should also be borne in mind that many TEs (including composite transposons and TMos) cannot be distinguished in bacterial genomes by classical in silico sequence analysis, unless they have been inserted into a highly conserved genetic context (e.g. a trap plasmid selection cassette), to enable precise definition of their termini. For this reason, the identification of functional TEs using trap plasmids may produce many interesting and surprising findings even when carried out in bacteria whose genomes have been fully sequenced.To conclude, the analysis performed in this study together with our previous work concerning the identification of diverse TMos generated by a single copy of ISParacoccus spp. has also generated considerable interesting and unique data concerning the dynamics of the process of transposition of IS-families identified in Paracoccus spp. . The sequences used for the comparisons were obtained from the ISfinder database (http://www-is.biotoul.fr/is.html). Sequence alignments were performed with the Pictogram program .

In the consensus sequences, shown below each Pictogram, uppercase letters indicate conservation within the IS family, lowercase letters indicate the predominant nucleotides, and dots indicate non-conserved residues.

This condition is diagnosed commonly as Gastroesophageal reflux disease with milk allergy but this fails to recognise the significant mid and lower bowel component in most of these children, which can be considered as an allergic inflammatory bowel disease. It is neither necessary nor essential to biopsy all these children in view of the response to anti allergy and anti inflammatory measures as well as the large number of children with this problem.

Many products for rapid dengue diagnosis are available in the market; the performance of few selected products was evaluated and compared with enzyme linked immuno sorbent assays (ELISA).Methods: Sera from a large number of patients (n=184) admitted to National Institute of Blood Diseases & Bone Marrow Transplantation (NIBD) were used to determine the efficiency of non-structural (NS) 1, IgA, IgG and IgM based rapid test devices for dengue diagnosis.Results: The dengue NS1 antigen based device was least efficient while among the antibody based devices the dengue IgA rapid test (RDT) was comparatively better . This device could detect both primary and secondary dengue infection and was found to be the most sensitive device at all point of sample collection.Conclusion: The dengue IgA RDT could be a cost effective and efficient rapid test device for timely dengue diagnosis at all levels of healthcare settings. DHF is a vasculopathy characterized by capillary leakage and haematological deregulation; may result in fatal outcomes.8 An early and accurate diagnosis of dengue is important which assist not only in patient management by directing clinical attention but also in initiating community scale preventive measures for vector control to alleviate further dengue transmission. Commercial ELISA tests as well as immunochromatographic tests (RDT) that detect anti-dengue antibodies and the dengue NS1 antigen in plasma/sera have provided a new avenue for diagnosing dengue.9,10 In addition to this, the inexpensive and accurate dengue RDTs may also be useful in dengue epidemiological studies in resource limited countries. The primary and secondary dengue infections are diagnosed by the detection of either IgM or IgG or both in patient\u2019s serum.8 These anti-dengue antibodies appear late in serum i.e. after 5-6 days of infection so NS 1 protein is detected in routine diagnosis during this period. The NS1 antigen appears in high concentration during the first few days of illness and it stays in serum after the infection subsides i.e. up to 14 days.10,11 Beside viral antigen detection a newer approach to dengue diagnosis is the use of anti-dengue IgA based RDT devices.12 IgA is the principal secretory antibody and human serum contains very low concentration of IgA1. During secondary dengue infection considerable increase in serum anti-dengue IgA is observed. The anti-dengue IgA is documented as the first antibody to appear in case of secondary dengue infection prior to IgG and IgM production while in case of primary infection it is produced after the anti-dengue IgM antibody due to class switching.13In the past few decades dengue has become a global health problem infecting millions of individuals annually.14 In this report three commercially available rapid diagnostic test devices were compared. Serological tests for dengue NS1 antigen, dengue IgA, dengue IgG/ IgM antibodies were carried out to demonstrate the potential application of these kits in early laboratory diagnosis of dengue infection with the special emphasis on utility of dengue IgA RDT as one of the new dengue diagnostic markers.12 The results were also compared with more specific and sensitive gold standard methods of dengue diagnosis i.e. IgG and IgM capture ELISAs.In Karachi, most of the clinical diagnostic facilities are using commercial immunochromatographic rapid tests (RDT) from international manufacturers relying only on the supporting literature on the efficiency of these devices. No local data on the efficacy and sensitivity of most of these tests is documented.Study design: A panel of 184 dengue disease suspected human serum samples was used for the evaluation of efficacy of dengue immunochromatographic tests (RDT).8 The study was conducted during the period of August to December 2010 at National Institute of Blood Diseases (NIBD). A signed informed consent form and detailed questionnaire were obtained from patients involved in this study following institutional review board (IRB) policies. Age range of the study population was 2-65 years.8 In the present study any sample positive for either dengue specific-antigen (NS1) or antibodies (IgM or IgG or IgA) by RDT screening was considered as positive dengue case. All samples were characterized using dengue acute diagnostics: NS1 Ag Rapid Test , ASSURE\u00ae dengue IgA Rapid Test and dengue Duo Cassette . The efficiencies of all these devices were evaluated by comparing with dengue IgM capture ELISA and dengue IgG capture ELISA . Complete blood count (CBC) was performed; after proper mixing by automated hematological analyzer; Sysmex XE-2100 ; to evaluate the clinical parameters of dengue diagnosis .A probable dengue case may be a patient with presentation of defined clinical symptoms and history of acute febrile illness of 2\u20137 days with or without haemorrohage.Dengue Antibodies ELISAs: Dengue IgM-Cap ELISA and IgG-Cap ELISA were used to detect dengue antibodies as per manufacturer\u2019s instruction. Briefly, 100 \u00b5l/well of patient sera (diluted 1:100) and controls were added to the assay plate coated with either anti-human IgM or anti-human IgG to capture the IgM or IgG. Both plates were incubated for one hour at 37C. Then the plates were washed and 100 \u00b5l/well of enzyme conjugate was transferred to the assay plates except the blank wells. After 10 minutes, the reaction was stopped by addition of 100 \u00b5l/well 1 M phosphoric acid. The OD values were determined at 450 nm. A sample was defined as positive when ratio of sample absorbance and calculated cut-off value was > 1.Dengue NS1 Ag Rapid Test: Dengue NS1 Ag Rapid Test is a one-step chromatographic assay which uses murine monoclonal antibodies to capture dengue virus NS1 antigen in human serum or plasma and detected by NS1 antigen polyclonal antibodies conjugated with gold colloid. Assays were conducted and results were interpreted according to the instruction of manufacturers.Dengue IgA Rapid Test: ASSURE\u00ae Dengue IgA Rapid Test (WO 2009/139725 ) is a reverse flow technique (US Patent-6316205) immunochromatographic rapid test for the qualitative detection of anti-dengue IgA from patient\u2019s biological samples . In this platform, test sample migrates upwards from the sample well and eventually form antibody-antigen complexes with dengue virus antigens in the test window. The bound antibody-antigen complexes is subsequently detected by goat anti-human IgA gold conjugate carried by chase buffer that flows downwards giving a pink-purplish color line in the test window. Control line which contains protein L captures human IgA from patient\u2019s sample and binds with the anti-human IgA-gold conjugate, resulting in pink-purplish color line in the control window. The appearance of control line indicates the proper addition and migration of serum sample and chase buffer. The test was performed as per manufacturer\u2019s instruction for use (IFU) and results were interpreted according to the intensity scale provided with the kit box without knowledge of the results of other tests.Dengue Duo IgM/IgG Cassette: Dengue Duo Cassette is a lateral flow based immunochromatographic rapid test for the qualitative detection of anti-dengue IgM and IgG from patient\u2019s biological samples . The device is designed to detect IgM antibodies to dengue, as well as elevated IgG titers that are indicative of a secondary infection. The rapid tests were read and interpreted according to the manufacturers' instructions. The positivity of individual marker were calculated separately (IgM or IgG) as well as in combination (IgM and IgG).Statistical analysis: The quantitative variables were expressed as mean, standard deviation, confidence interval and minimum and maximum range. The qualitative variables were mentioned as percentages. The sensitivity and specificity of immunochromatographic tests were analyzed by 2x2 table using MedCalc statistical software, version-11.5 . Kappa value was used to test the efficiency and reliability of the rapid devices.Characteristics of the study population: The characteristics of the study population (n = 184 cases) that contributed acute sera to the test panel is shown in Sensitivity and specificity of dengue immunochromatographic tests versus reference dengue tests: The sensitivities and specificities of three RDTs against the reference tests i.e. dengue IgM-cap ELISA and IgG-cap ELISA are presented in Immunochromatographic tests sensitivity in primary or secondary infection: The detection of both dengue primary and secondary infected patients by dengue IgA RT was significantly higher than Panbio IgM/IgG Duo RDT and is presented in Sensitivity of Immunochromatographic tests by day of illness: The sensitivity of three RDTs was also evaluated based on the duration of onset of dengue fever, categorized into 6 groups and 86.05% (80.95%) respectively. Additionally, the level of detection of infection at all stages of disease by IgA RDT was far better false negative results. Dengue NS-1 antigen can be found in patient\u2019s serum until the production of anti-NS-1 IgG or in some instances a few days after defervescence. The variable levels of NS-1 antigen in different phases of infection might be due to the immune-complex formation of NS1 antigen with anti-dengue IgG resulting in less sensitive dengue detection in acute-phase secondary infection as reported previously.21We conclude that the serological testing for early diagnosis of dengue infections could be accomplished by using IgA based RDT at all heath care settings during any stage of infection cycle. Moreover, it partially overcomes the limitations associated with ELISAs like handling of single sample without delay."} +{"text": "The cGMP-dependent protein kinase (PKG) is widely expressed in mammalian tissues and serves as an integral component of second messenger signaling in a number of biological contexts including vasodilation, motility and memory .

Associations of genital HIV shedding with HIV plasma viral load (PVL), herpetic lesions, HSV shedding and other factors were examined.10 copies/mL) was closely associated with HIV PVL and HSV shedding but not the presence of herpetic lesions .Prevalence of detectable genital HIV RNA varied from 73% in HSV-2 seronegative women to 94% in women with herpetic lesions . In paired specimens from HSV-2 positive women, genital HIV viral shedding was similar during symptomatic and asymptomatic visits. On multivariate regression, genital HIV RNA (logHIV PVL and HSV shedding were more important determinants of genital HIV than the presence of herpetic lesions. These data support a role of HSV-2 infection in enhancing HIV transmissibility. Herpes simplex virus type-2 (HSV-2) infection is lifelong and a common cause of genital ulcers In vitro studies provide evidence of the effect of HSV-2 infection on HIV replication The frequency of recurrent episodes of clinical herpes and of subclinical viral shedding varies both between individuals and over time within the same individual The objectives of this study were to compare the presence and quantity of cervicovaginal HIV in HIV seropositive women living in Mbeya Region, Tanzania with clinical episodes of herpes, subclinical HSV-2 infection and without HSV-2 respectively; to examine the association between genital shedding of HIV and HSV-2; and to investigate factors influencing the quantity of HIV genital shedding.As part of a study of the determinants of HIV super-infection in Mbeya Region, Tanzania, an open cohort of 600 female barworkers aged 18 to 35 years was established in late 2000. Study procedures have been described previously Treponema pallidum particle agglutination assay and the rapid plasma reagin test .A diagnostic algorithm including two different enzyme-linked immunosorbent assays and a Western Blot assay was used to determine HIV serostatus. Type-specific serological testing for HSV-2 was also performed by enzyme immune assay . Syphilis testing was carried out using the Serodia HIV-1 plasma viral load (PVL) was quantified by transcription polymerase chain reaction (PCR) , with a detection threshold of 50 HIV-RNA copies/ml.T pallidum, H ducreyi and HSV A single dry swab was taken from genital ulcers and multiplex PCR (M-PCR) was used for the detection of 6 cells for HIV-1 DNA. Cervicovaginal specimens were also tested for prostate specific antigen (PSA) using the VITROS immunodiagnostic product PSA reagent and calibrator packs on the automaton Ortho-Clinical Diagnostics VITROS Eci , and for traces of haemoglobin using Multistix 8 SG strips .Cervicovaginal secretions (CVS) were collected from all women at every study visit using standard vaginal lavage procedures Trichomonas vaginalis by direct microscopy of a wet mount preparation and Candida albicans by wet mount preparation and gram stain.Vaginal swabs were tested for CVS specimens collected from HIV seropositive women at 3-monthly study visits were excluded from analyses if (i) the woman had a genital lesion of non-herpetic origin (12 specimens were excluded for confirmed syphilis and 7 specimens excluded for chancroid), (ii) there were traces of haemoglobin in the specimen or (iii) the specimen was positive for PSA. Specimens from (i) were excluded as HSV shedding may have been influenced by other ulcerative STIs, and those from (ii) and (iii) were excluded as any HIV-RNA or HIV-DNA found in the genital tract may not have been attributable to genital shedding from the woman. Specimens were categorised into four study groups according to the woman\u2019s HSV-2 serostatus and the presence or absence of confirmed herpetic genital lesions at the time of specimen collection. Women who experienced PCR-confirmed herpetic lesions at one or more study visits contributed to two study groups: Group 1 included CVS specimens collected in the presence of herpetic lesions; Group 2 , included specimens taken from the same women at follow-up examinations at least 6 months after or 6 months before the visits at which herpetic lesions were detected. In Group 3 (\u201cnever lesions\u201d) a random sample of specimens were taken from HSV-2 seropositive women who never had herpetic genital lesions or a history of genital lesions at any of the study visits. Group 4 (\u201cHSV-2 negative\u201d) was randomly chosen from specimens taken from women not infected with HSV-2.10) transformations were applied to plasma and genital viral loads for HIV and HSV-2 to obtain approximately normal distributions, geometric means (GM), and 95% confidence intervals (95%CI). Differences in mean viral loads between groups were assessed using a random effects linear regression model to account for correlations within subjects. Correlations between viral loads were assessed using Spearman\u2019s rank correlation coefficient.Differences between study groups in proportions of CVS specimens with HIV-1 (RNA and DNA) and HSV DNA above the detection threshold were tested using random effects logistic regression modelling to account for correlations within subjects. Analyses of quantity of genital viral shedding were restricted to specimens with viral loads above the threshold of detection. Logarithmic .Initial analyses suggested that HSV shedding was a strong determinant of genital HIV shedding. We regrouped specimens of HSV-2 seropositive women in the subclinical and never lesions groups according to the presence of HSV shedding (asymptomatic HSV shedders) or absence of HSV shedding (HSV non-shedders). We then used random effects linear regression, accounting for multiple observations from the same individual, to examine the association of log-transformed HIV genital viral loads with HSV shedding status as well as other potential risk factors, including age, laboratory-diagnosed non-ulcerative sexually transmitted infections (STI), signs or symptoms of sexually transmitted diseases (STD), enlarged lymph nodes and HIV plasma viral load. In this analysis, specimens with HIV or HSV genital viral load below the threshold of detection were assigned a value of half the threshold.Analyses were performed using Stata 11.0 . The study was approved by the national ethics review committee of the National Institute for Medical Research of the United Republic of Tanzania and the LSHTM Ethics Committee . It was conducted within the framework of the Mbeya Medical Research Programme. All participants provided written, informed consent to participate in the study.Analyses were based on 221 eligible CVS samples from 131 HIV seropositive women. The four study groups comprised 57 women at 70 study visits with clinically manifest genital herpes (Group 1), 39 of the same women at 46 study visits when they did not have visible ulcers (Group 2), 55 HSV-2 seropositive women at 60 study visits who were never observed with herpetic lesions (Group 3), and 18 women at 45 study visits who were HSV-2 seronegative (Group 4) .Thirty-five women contributed to both Groups 1 and 2; four other women in Group 2 were not sampled at the time of clinical herpes. Three women were HSV-2 seronegative (Group 4) and later seroconverted, two with an episode of clinical herpes (Group 1) and one with no episode of clinical herpes (Group 3). Thirty-three women contributed more than one specimen to the same study group (up to 7 specimens from one HSV-2 seronegative woman).Mean age was around 28 years for HSV-2 positive women and 25 years for HSV-2 negative women. Slightly higher proportions of women were using hormonal contraception among those who had never had lesions, and those who were HSV-2 negative, but this difference was not statistically significant (p\u200a=\u200a0.35).C Albicans was most common in the never lesions group (p\u200a=\u200a0.08), but other STI or clinical signs of STD at the time of specimen collection did not differ significantly by study group in samples from women uninfected with HSV-2 and highest in samples from women with confirmed herpetic lesions. TPPA seropositivity, indicating past or current syphilis, was also lower in the HSV-2 uninfected group (p<0.001), and dy group .The prevalence of detectable genital HIV RNA was lowest in the HSV-2 negative group (73%) and highest in the clinical herpes group (94%) . The gen6 cells) and the lowest in the never lesions group (GM\u200a=\u200a141 copies per 106 cells) . The pattern was less clear than for HIV RNA, but the highest viral load was seen in the clinical herpes group (GM\u200a=\u200a252 copies per 106 cells) .All women with detectable genital HIV RNA also had detectable plasma HIV RNA. Among women with detectable genital HIV RNA, quantities of plasma and genital HIV RNA were significantly correlated .As expected, the prevalence of detectable genital HSV DNA varied substantially between the three study groups of HSV-2 positive women, with a much higher prevalence among women with clinical herpes (77%) than in the subclinical herpes (20%) and never lesions (12%) groups (p<0.001). HSV DNA viral load showed a similar, though non-significant trend .Of the 35 women who had specimens taken during clinical episodes of herpes and also at visits when they were asymptomatic, 30 (86%) had detectable HIV RNA on both occasions, while all 29 women with paired specimens analysed for HIV DNA were positive on both occasions. There was no evidence of a difference in the quantity of genital HIV shed between clinical and subclinical phases of herpes . AlthougTo explore whether signs of clinical herpes or HSV-2 viral shedding were more important determinants of HIV shedding, we re-categorised the specimens into four new groups: clinical herpes, HSV-2 seropositive with detectable genital HSV DNA shedding (asymptomatic HSV shedders), HSV-2 seropositive without detectable genital HSV shedding (HSV non-shedders at that visit), and HSV-2 seronegative. In all four groups, the majority of specimens had detectable HIV RNA and HIV DNA, and the prevalence was highest in samples taken during clinical or subclinical shedding episodes . OverallAmong specimens with HSV DNA shedding (with or without lesions), the genital viral loads of HIV RNA and HSV DNA were positively correlated . The correlation of genital HIV DNA and HSV DNA was weaker , as was the correlation between plasma HIV RNA and genital HSV DNA . A positive correlation between genital and plasma viral loads of HIV was seen in all women . While tGenital HIV RNA viral load increased with quantity of HIV PVL (p<0.001) and presence and quantity of genital HSV DNA . AlthougSimilarly, genital HIV DNA viral load increased with both HIV PVL (p<0.001) and genital HSV DNA viral load . AlthougIn this study we determined the frequency and quantity of cervicovaginal HIV and HSV using specimens collected from 131 HIV infected women who were followed up every three months for up to 30 months. The prevalence of detectable genital HSV DNA in asymptomatic HIV positive women was similar to studies from elsewhere in Africa The main objective of our study was to determine whether genital shedding of HIV occurred more frequently in the presence of genital herpetic lesions. A strength of the study was the long follow-up period, providing an opportunity to observe women both during and between clinical episodes of herpes. Clinical herpes was associated with higher levels of genital HIV shedding, but only partially as there were episodes of herpetic ulceration where HSV genital shedding was not recorded, and conversely episodes of HSV genital shedding in asymptomatic women. In the multivariate analysis, we clearly saw that herpetic ulcers were not independently associated with genital shedding of HIV RNA , whereas there remained a clear association between HSV genital shedding and genital shedding of HIV RNA , suggesting that this increase was related to the quantity of genital HSV and the HIV plasma viral load rather than to the presence or absence of herpetic lesions. In paired specimens taken from women with clinical herpes and from other study visits when they were asymptomatic, no difference was seen in HIV genital shedding at the two visits. When the original study groups were rearranged to examine the effect of genital HSV shedding, there was a clear difference in HIV genital shedding between HSV shedders and non-shedders, but no additional increase in HIV shedding in those with clinical herpes. Similarly, when risk factors for HIV genital shedding were examined in a multivariate regression analysis, the quantity of genital HIV RNA or DNA was significantly associated with HIV plasma viral load and HSV shedding, but after adjustment for these factors was not associated with clinical herpes.Our findings are consistent with results from a study carried out in Bangui, Central African Republic, where among HIV positive women shedding HSV, there was a significant correlation between genital HIV RNA shedding and genital shedding of HSV The observational design of these studies limits inferences about causality, but stronger evidence concerning the effect of herpes on HIV infectivity comes from seven recently completed randomised controlled trials of herpes suppressive therapy. Four trials, using valacyclovir or high dose acyclovir (800 mg b.i.d.), found significant reductions in PVL as well as significant reductions in rectal and cervicovaginal HIV-1 RNA concentrations Our results are consistent with previous reports of an association between HSV-2 shedding and HIV PVL, and suggest that clinical and subclinical herpetic reactivations might increase genital HIV shedding not only through a direct viral interaction at the genital level, but also through their systemic effect on plasma HIV viral load In this study we used cervicovaginal specimens as a marker of genital shedding, and did not find evidence of increased HIV shedding in the presence of genital lesions. However, HIV shedding may also occur directly from a herpetic lesion, and we cannot exclude the possibility that overall HIV infectivity is increased in the presence of lesions, particularly as 64% of herpetic lesions seen in this study were found on the vulva T pallidum or H ducreyi) were excluded from this analysis, as were specimens with traces of blood or semen, although we cannot rule out the possibility that some HIV or HSV detected in CVS originated from infected sexual partners. Some CVS were collected from women with non-ulcerative STI, and this may have led to underestimation of the association between herpetic lesions and HIV shedding, as cervicovaginal secretion of HIV-1 has been associated with the presence of non-ulcerative STI such as gonorrhoea and Chlamydia and found to decrease after effective treatment Genital specimens from women with ulcers of other confirmed aetiology (Increased genital HIV-1 viral load has been shown to be associated with immunosuppression in some studies In conclusion, this study adds to the accumulating evidence that HSV-2 infection increases genital shedding of HIV, and may therefore increase the infectivity of HIV infected individuals to their sexual partners. Our data suggest that the increase in HIV shedding is related to the quantity of HSV shedding rather than to the presence of clinical lesions of herpes. These findings emphasise the importance of developing and evaluating effective interventions to control herpes in populations where HSV-2 may account for a substantial proportion of HIV transmission."} +{"text": "Energy therapies in the hospital setting are met with various levels of acceptance due to questions of efficacy and evidence base.

In a gene-based association analysis, MIR4301 (micro-RNA4301), which resides in an intron of DRD2, was the most significant gene . Examining 27 of the previously reported SBP associated SNPs, 4 SNPs were nominally significant. A genetic risk score was constructed to assess the aggregated genetic effect of the published SBP variants, demonstrating a significant association (P=0.05). In addition, we also assessed whether these variants are associated with SCI, validating the use of SBP as an endo-phenotype for SCI. Three SNPs were nominally associated, and only rs2357790 (5\u2019 CACNB2) was significant for both SBP and SCI. None of these SNPs retained significance after Bonferroni correction. Taken together, our results suggest the importance of DRD2 genetic variation in the modulation of SBP, and extend the aggregated importance of previously reported SNPs in the modulation of SBP in an African American cohort, more specifically in children with SCD.In pediatric sickle cell disease (SCD) patients, it has been reported that higher systolic blood pressure (SBP) is associated with increased risk of a silent cerebral infarction (SCI). SCI is a major cause of neurologic morbidity in children with SCD, and blood pressure is a potential modulator of clinical manifestations of SCD; however, the risk factors underlying these complications are not well characterized. The aim of this study was to identify genetic variants that influence SBP in an African American population in the setting of SCD, and explore the use of SBP as an endo-phenotype for SCI. We conducted a genome-wide meta-analysis for SBP using two SCD cohorts, as well as a candidate screen based on published SBP loci.

This does not preclude support for a center of origin hypothesis that suggests increased speciation in the region may contribute to species richness. In addition, consistent retention of sea surface temperatures in models suggests that available kinetic energy may also be an important factor in shaping patterns of marine species richness. Kinetic energy may hasten rates of both extinction and speciation. The position of the Indo-Pacific Warm Pool to the east of the Coral Triangle in central Oceania and a pattern of increasing species richness from this region into the central and northern parts of the Coral Triangle suggests peripheral speciation with enhanced survival in the cooler parts of the Coral Triangle that also have highly concentrated available habitat. These results indicate that conservation of habitat availability and heterogeneity is important to reduce extinction of marine species and that changes in sea surface temperatures may influence the evolutionary potential of the region.Range overlap patterns were observed in a dataset of 10,446 expert-derived marine species distribution maps, including 8,295 coastal fishes, 1,212 invertebrates (crustaceans and molluscs), 820 reef-building corals, 50 seagrasses, and 69 mangroves. Distributions of tropical Indo-Pacific shore fishes revealed a concentration of species richness in the northern apex and central region of the Coral Triangle epicenter of marine biodiversity. This pattern was supported by distributions of invertebrates and habitat-forming primary producers. Habitat availability, heterogeneity, and sea surface temperatures were highly correlated with species richness across spatial grains ranging from 23,000 to 5,100,000 km Persistent questions remain regarding the origins of the uneven distribution of marine species richness across the tropical Indo-Pacific The tropical Indian and Pacific Oceans encompass about two thirds of the earth\u2019s equatorial circumference and include two distinct marine zoogeographic regions The observation that peaks in marine species richness throughout geologic time follow changing concentrations of available habitat is an extension of the area of refuge hypothesis, one of the numerous hypotheses invoked to explain the current epicenter of marine biodiversity in the Coral Triangle In addition to area of refuge, other hypotheses used to explain the current epicenter of marine biodiversity can be summarized as: 1) center of origin A neutral hypothesis has also been tested relating to the mid-domain effect The area of refuge hypothesis was primarily formulated as an alternative to the well-established center of origin hypothesis which heavily relies on assumptions about dispersal One component of the area of refuge hypothesis is habitat heterogeneity, which has long been considered important in shaping species diversity patterns It has long been established that there are latitudinal gradients in species richness with highest species richness in the tropics linked to multiple potential factors A number of different methods have been used to examine causes of the uneven distribution of marine species across the Indo-Pacific The study range covers the entire Indian Ocean (including Red Sea and Persian Gulf) and the entire Pacific Ocean between 30\u00b0N and 30\u00b0S. All data layers were projected onto the World Cylindrical Equal Area coordinate system centered at 130\u00b0 longitude.2/grid cell, except for the grids located along upper and lower edges of the study area which cover less area. To compare the effect of area distortion, we used, five different equal area grids: small , medium , large , extra large , and largest . The use of different grid sizes was not to test for the best possible grain but to test at which grain the predictors are likely to operate The study area was divided into equal grids of different horizontal resolutions and the commonly-used Universal Transverse Mercator (UTM) grid to test the grid choice effects on relationships between predictors and species richness. Different orientations of centroid location were tested and found to have minimal effects , S2 so tThe aim of this study was to test for effects of available nearshore habitat on species diversity, and therefore, relates to pelagic, benthic, or demersal species found primarily over continental or island shelves. The total number of species maps produced in this study was 10,446 of which2) from a 200 m bathymetry layer processed from ETOPO1 raster data Using a Geographic Information System (GIS), we calculated the amount of continental shelf or shallow water area (SW) for each habitat and N\u200a=\u200atotal habitat area .The SST layer was developed from the monthly long-term SST data derived from the National Oceanic and Atmospheric Administration Optimum Interpolation dataset. This product was constructed from two intermediate climatologies to produce a 1\u00b0 resolution dataset with a 1961\u20131990 base period y is fitted as a Poisson variable. Using the log of y we fit the GLM as below:o, \u03b21\u03b2, 2\u03b2, 3\u03b2, and 4\u03b2 are the parameter estimates. For SLM, we used maximum likelihood estimation of spatial simultaneous autoregressive error model in the form:Range overlap maps and environmental layers were combined to form grid matrices with the corresponding values of species richness, habitat availability , two habitat heterogeneity indices , SST and NPP in each cell. Statistical analyses were performed to test the relationship between the environmental variables versus four different species richness subgroups: combined all species, all fish species, all habitat-forming species , and all invertebrate species. We modeled the influences of habitat area and heterogeneity to each subgroup using both a generalized linear model (GLM) and a spatial linear model (SLM) to account for spatial autocorrelation \u03b2 is the vector of coefficient for intercept and explanatory variable X; \u03bb is the spatial autoregression coefficient; W is the spatial weights; \u03bc is the spatially-dependent error term; and \u03b5 is the error vector. Likewise, the Poisson response variable y was also fitted as a log function.2R values were used as a guide to model selection by evaluating the amount of variation explained. Since an equivalent 2R does not exist in spatial analysis with a logistic regression, we used pseudo-2RIWe performed SLM with spatial distance weights derived from five nearest-neighbor cells. We used five and not eight nearest neighbors since most of the cells are isolated creating coastal and island effects. The presence of isolated cells will create a bias in spatial weight distance calculation. To normalize the data, all variables (dependent and independent) were log-transformed. Pearson correlation coefficients were generated for all between-variable comparisons. We tested individual habitat predictors versus each subgroup using single-predictor models. Then we used multiple-predictors model to test the effects of the combination of different habitats in each subgroup. The effects of multiple predictors were further explained by identifying the minimal-adequate model using backwards elimination method. Model fit was assessed using t-values (GLM) and z-values (SLM) for both single and multiple-predictor relationships. In GLM, adjusted Species richness across the Indo-Pacific showed the expected pattern of highest richness in the Coral Triangle . The cenGreatest shallow water area (SW) and longest coastline (CL) per unit area , 3A wereAverage SST values were highest (over approximately 29\u00b0C) around and east of the Solomon Islands and northern Australia and were also high (over approximately 28\u00b0C) in eastern central Indonesia, western Sumatra and northwestern Madagascar . SpeciesPredictor variables were consistently highly correlated with one another at all scales, with some notable exceptions . SW and Species richness of all taxonomic sets was significantly correlated with most environmental variables at all scales in single predictor GLM and SLM with the exception of insignificant correlations with SST at the smallest grid sizes, insignificant correlations with NPP at nearly all grid sizes, and HDIa and some other variables at the larger grain sizes . CL mostI indicated significant autocorrelation at all grains sizes except the largest grain size. As expected with increasing grains size and decreasing sample sizes, R2 and pseudo-R2 increased (less variation to explain) and AIC values decreased with larger grain sizes (less entropy to account for). However, when comparing equal grain sizes between GLM and SLM the correction for significant autocorrelation always improved the model (higher pseudo-R2 versus R2 and lower AIC). CL was consistently retained in all SLM for all taxonomic sets at all grain sizes except in the largest grain size. In SLM across all taxa most consistently retained were SW at smallest and largest grain sizes, HDIa at smallest grain size and variably in large grain sizes, HDIn and SST mostly at all grain sizes except small and medium, and NPP negatively correlated and variably retained at larger grain sizes.Multiple regression results were similar to single predictor results in that many environmental variables were significant and retained in models . GLM andRange overlap of 10,44The pattern of species richness in this study is dominThe high correlation among our predictor variables and the I test shows significant effects of autocorrelation in our data (R2 than R2) and more entropy removed from the model (lower AIC). When comparing models based on the same grid size, correction for autocorrelation resulted in a lower AIC, and therefore, SLM is the preferred model The choice of best predictors for species richness is influour data similar our data consisteR2 values increase with increasing grid size over the same area since there is less variation to explain with smaller sample sizes is not statistically defensible le sizes . Similar2 a habitat heterogeneity index similar to HDIn may suffice in addition to CL as a proxy for habitat availability. Differences in how the different habitat complexity indices behave in models are a result of the form of complexity they emphasize. Our HDIa index is based on the relative proportion of area for our different habitat types in a grid. Heterogeneity is negatively correlated with shallow water area and the available kinetic energy predictor variable (SST) are consistently retained as positive significant predicator variables across species groups and grid sizes, accounting for autocorrelation . Coastliter area because ter area . HDIn ister area . FurtherThe position of the Indo-Pacific Warm Pool appears to be a primary reason that available kinetic energy, as exemplified by SST, is most consistently retained in models with autocorrelation considered . LatitudOur results suggest that kinetic energy, habitat availability, and habitat complexity are all important in shaping species richness patterns across the Indo-Pacific but the relationship of these variables to area of refuge, area of accumulation, and center of origin hypotheses is not straightforward. The striking pattern of diminishing species richness away from the epicenter in the Coral Triangle was a factor in formation of both the center of origin and area of accumulation hypotheses, both mediated primarily by dispersal out of or into the Coral Triangle An alternative explanation for the pattern of increasing species richness into the Coral Triangle from the east and the correlation of SST with species richness is that the position of the Indo-Pacific Warm Pool is only a coincidence and does not influence speciation and extinction rates. If speciation within the Coral Triangle is the dominant factor then dispersal out of the Coral Triangle would rely on stepping stones of available habitat counter to prevailing currents over geologic time periods. There is some evidence for gene direction out of the Coral Triangle Habitat availability is central to both the center of origin and area of accumulation hypotheses but also to the neutral and eclectic hypotheses as well. The observed correlations among species richness, habitat availability, and habitat heterogeneity may simply be a function of the well-known species-area relationship This complex view of the area of refuge hypothesis supports the concept that both area of available habitat and complexity of available habitat are potentially important in models seeking to predict and conserve tropical marine species diversity. Shallow water area, as a measure of available habitat, is a significant component in shaping species richness in the region across different taxonomic groups. However, the largest shallow water area (the Sunda and Arafura shelves), does not coincide with the location of highest species richness . Available habitat in terms of shallow water area alone is not the optimal explanation for variation in species richness because coastline length and habitat heterogeneity are significant explanations for variation in species richness . BellwooAnother factor that may profoundly influence the role that available shallow water area plays in shaping biodiversity in the Coral Triangle is local extinction from glacial maxima and concomitant sea level lows. Marine life was extirpated on the extensive tropical sea floor represented by the Sunda and Arafura shelves several times during the Pleistocene Tittensor et al. (2010) th century Our findings further support previous studies based largely on different distribution databases Available habitat and habitat complexity both significantly explain variation in species richness, and therefore, the loss of these attributes may reduce diversity. Advances in our understanding of the different components of area of refuge may help more clearly define distinctions between available habitat and complexity of habitat. For example, more accurate mapping of presumptive keystone structures such as seagrass beds, mangrove areas, and coral reefs may improve the accuracy of habitat diversity indices. Testing additional types of habitat indices may also improve our understanding. Finding a practical alternative to grid-based spatial analyses may also improve resolution of the degree to which habitat availability components and factors such as SST explain variation in species richness. It is clear that habitat-based conservation efforts targeted at preserving biodiversity should aim to preserve both area and complexity of habitats. This effort is most crucial in the Coral Triangle where species richness is at its peak but it may also be very important in preserving the evolutionary potential of isolated islands, particularly those in the Indo-Pacific Warm Pool. Habitat destruction is a key factor linked to species threats in the Coral Triangle but fortunately, destruction is less intense at present in the islands of Oceania Figure S1Distribution pattern of shallow water extent in the Indo-Pacific at UTM grids shifted into different orientations.

Four numerically dominant pelagic species were included in our assessment, and larval density of each species was lower in 2010 than any of the three years prior to the oil spill, although larval abundance in 2010 was often statistically similar to other years surveyed. To assess potential overlap between suitable habitat of pelagic fish larvae and surface oil, generalized additive models (GAMs) were developed to evaluate the influence of ocean conditions on the abundance of larvae from 2007\u20132009. Explanatory variables from GAMs were then linked to environmental data from 2010 to predict the probability of occurrence for each species. The spatial extent of surface oil overlapped with early life habitat of each species, possibly indicating that the availability of high quality habitat was affected by the DH oil spill. Shifts in the distribution of spawning adults is another factor known to influence the abundance of larvae, and the spatial occurrence of a model pelagic predator (blue marlin) was characterized over the same four-year period using electronic tags. The spatial extent of oil coincided with areas used by adult blue marlin from 2007\u20132009, and the occurrence of blue marlin in areas impacted by the DH oil spill was lower in 2010 relative to pre-spill years. Pelagic fishes that frequent open oceans are valuable economically and influence the structure and resilience of offshore ecosystems 6 (\u00b120%) barrels of oil into the northern Gulf of Mexico (GoM) [9). Oil trajectory models predicted that surface or near surface oil covered a large region of the continental shelf and slope In April 2010, the Deepwater Horizon [DH) oil spill resulted in the release of approximately 4.4\u00d710Thunnus atlanticus), blue marlin (Makaira nigricans), dolphinfish (Coryphaena hippurus), and sailfish (Istiophorus platypterus). We first explored temporal variability during early life by contrasting larval abundances of each species before (2007\u20132009) and after (2010) the DH event. Next, generalized additive models (GAMs) were developed from 2007\u20132009 data to assess habitat associations, and then to predict the probability of occurrence the following year (2010) in relation to surface oil . Finally, patterns of occurrence for a model pelagic predator (blue marlin) over the same four-year period were examined using pop-up archival transmitting (PAT) tags, and light-based geo-locations from tags were used to compare the distribution of adults before and after the DH oil spill. Our working hypothesis was that the distribution and abundance of pelagic fishes in our study area, both early life and adult stages, may have changed in 2010 due to changes in habitat condition or other activities related to the DH oil spill. We fully recognize that natural environmental variability is known to influence the distribution and abundance of pelagic fishes in the northern GoM The aim of the present study was to assess possible impacts of the DH oil spill on four pelagic fishes that commonly inhabit outer shelf and slope waters of the northern GoM: blackfin tuna and the oceanographic factors that influence the abundance of larvae, inter-annual variability was investigated with separate models for June and July. In June surveys, a significant year effect was observed for all four species: blackfin tuna (p\u200a=\u200a0.030), blue marlin (p\u200a=\u200a0.001), dolphinfish (p\u200a=\u200a<0.001), and sailfish (p\u200a=\u200a0.006). Despite the fact that the mean density of each species was lower in June 2010 than any of the other June surveys , this yea concentration, depth, distance to feature, feature classification, salinity, sea surface temperature, sea surface height anomaly) on the occurrence of larvae varied across species and within species when contrasting June and July models and 44.3% (July). Final GAMs for dolphinfish retained three explanatory variables in the June model and four in the July model, with depth being the only variable common between the two models. Percent deviance explained for dolphinfish GAMs was 13.2% (June) and 13.5% (July). Final GAMs for sailfish included three common explanatory variables in June and July models , and percent deviance explained was 20.3% (June) and 15.3% (July).GAMs based on presence/absence data developed for each species indicated that the influence of 7 oceanographic factors varied markedly among species . The spaectively . High qu2 in both June and July.The spatial extent of surface oil from the DH event was viewed in relation to the total available area of high quality habitat predicted with GAMs to determine whether suitable habitat of each species was exposed to oil contamination. In June 2010, the estimated overlap between high quality habitat and surface oil was relatively low for blue marlin (0%) and sailfish (4.5%). Conversely, percent overlap for blackfin tuna and dolphinfish was considerably higher, with 15.3% and 13.9% of the predicted high quality habitat exposed to surface oil in the northern GoM. Species-specific patterns for July 2010 were similar, and again the percentage of high quality habitat exposed to surface oil was considerably lower for blue marlin (0.2%) and sailfish (7.2%) when compared to blackfin tuna (19.4%) or dolphinfish (11.4%). Given the predicted overlap observed for blackfin tuna, it is not surprising that the areal coverage of high quality habitat exposed to surface oil was relatively large, exceeding 60,000 km2 (9.3%) of the core use area in 2007\u20132009 was exposed to surface oil in 2010. Based on daily mean positions, we also observed that use of a region subsequently closed to fishing in 2010 by the National Oceanic and Atmospheric Administration and after (2010) the DH oil spill . From 20Both the abundance and percent occurrence of fish larvae for selected pelagic fishes declined in 2010 relative to the three years prior to the DH oil spill, suggesting that changes in environmental conditions, possibly linked to the presence of oil and dispersants, may have contributed to observed inter-annual variability. Previous studies have demonstrated a clear relationship between these contaminants and the demographics of a wide range of marine organisms including invertebrates, fishes, birds, and mammals Although results from this study suggest a possible connection between reduced abundance of pelagic fish larvae in 2010 and the DH oil spill, inter-annual variability is relatively common for cohorts of pelagic larvae in the GoM Variability in mesoscale circulation has been shown to influence the spatial distribution of larvae in the GoM Determining the primary cause of annual fluctuations in the abundance of pelagic fish larvae is challenging, and establishing a direct link between the abundance of larvae and the DH oil spill is not possible given the data available. However, our estimates of overlap between surface oil and high quality habitat of billfish, dolphinfish, and tuna larvae, support the premise that highly suitable nursery areas (or spawning areas) of these taxa were impacted by the DH oil spill. Oil contamination occurred across several hundred thousand square kilometers of suitable habitat of pelagic fish larvae, accounting for approximately 10\u201320% of the available high quality habitat for blackfin tuna and dolphinfish in the northern GoM. Estimates of percent overlap were lower for billfish larvae , and suitable habitat for these taxa appeared to be more limited in coverage and farther offshore , possibly out of reach of significant oil contamination from the DH oil spill. While the presence of surface oil may have impacted larval survival within a restricted area, the majority of the high quality habitat for each species occurred in areas of the northern GoM unaffected by the oil spill. Therefore, anticipated effects of the DH oil spill on early life survival or reduced larval abundance are expected to be relatively modest, which interestingly is in accord with observed annual patterns of abundance.Apart from early life processes that directly impact the dispersal and survival of larvae, differences in the demographics (age structure) and abundance (spawning stock biomass) of spawning adults can also influence the abundance of larvae within a given area The influence of direct and/or indirect effects of the DH oil spill on the abundance and distribution pelagic fishes is currently unresolved, and caution must be exercised when interpreting time-series data that are limited in scope and duration. While larval abundances of all four species examined were lower in 2010 relative to the three-year baseline sample, abundance in 2010 was statistically similar to at least one of the other years surveyed, suggesting that observed declines are within the bounds of expected natural variability. Despite the fact that we cannot explicitly link observed inter-annual trends in the abundance of larvae to the DH oil spill, we can conclude that large areas of high quality habitat of pelagic fishes were exposed to oil contamination. In turn, oil contamination may have contributed to observed temporal patterns of abundance, but the main driver of observed temporal patterns is unknown.Ichthyoplankton surveys were conducted over a four-year period (2007\u20132010) from approximately 26.5 to 28.0\u00b0N latitude and 87.5 to 92.0\u00b0W longitude in the northern GoM. Summer surveys were conducted each year during the same two months , which corresponds to the primary spawning periods of many pelagic fishes in the GoM Thunnus atlanticus (family Scombridae), blue marlin Makaira nigricans and sailfish Istiophorus platypterus (family Istiophoridae), and dolphinfish Coryphaena hippurus (family Coryphaenidae). Density at each station was determined by combining numbers of individuals in both 500 and 1200 \u00b5m mesh nets and adjusted to reflect a sampling depth of 0.75 m. Average volume of water sampled with both nets at each station was approximately 3500 m3. Percent occurrence at the species level was also determined and based on the number of stations where selected taxa were present divided by the total number of stations sampled.Fish larvae were sorted in the laboratory, and density and occurrence were determined for blackfin tuna Thunnus) to species was based on sequence variability of mitochondrial DNA [41) and High Resolution Melting (HRM) assays based on fixed nucleotide differences among species Thunnus larvae to determine the abundance of blackfin tuna (T. atlanticus) in our collections. Two congeners were also present in our collections , and blackfin tuna accounted for nearly 90% of the Thunnus larvae collected.Fish larvae were identified visually to family level based on anatomical and morphometric features Temporal differences in the densities of larvae collected over the four-year period were compared with a Kruskal-Wallis (rank sums) one-way analysis of variance (ANOVA). This non-parametric method does not assume a normal distribution, which was required due to the large number of zero values in our data set (skewed distribution). Species-specific models were developed for each species in both June and July to investigate temporal differences in larval density for all four species. Non-parametric multiple comparison tests (Wilcoxon method) were run to determine which factor levels or years differed from others. Statistical significance for all tests was based on \u03b1\u200a=\u200a0.05.a, depth), and parameters related to mesoscale oceanographic features were used to investigate the influence of environmental conditions on the occurrence of each species.

PAT tag data from deployments prior to the DH oil spill (n\u200a=\u200a13) ranged from 60 to 365 days. Daily mean positions of adult blue marlin after the spill were based on geo-location estimates generated from 1-year tag deployments on blue marlin (n\u200a=\u200a4). These fish were tagged in summer/fall 2009 and the tags released from fish during or after July 2010. Our analysis is based on the assumption that individuals return to the same general spawning area the following year, which is supported by long-term tag deployments on blue marlin and white marlin before or after 2010 .

Cardiovascular disease is characterized by decreased NO-sGC-cGMP signaling. Pharmacological activators and stimulators of sGC are being actively pursued as therapies for acute heart failure and pulmonary hypertension. Here we review molecular mechanisms that modulate sGC activity while emphasizing a novel biochemical pathway in which binding of the matricellular protein thrombospondin-1 (TSP1) to the cell surface receptor CD47 causes inhibition of sGC. We discuss the therapeutic implications of this pathway for blood flow, tissue perfusion, and cell survival under physiologic and disease conditions. Cardiovascular disease is the number one cause of death worldwide and remains a burdensome health problem. Understanding the underlying molecular mechanisms of cardiovascular disease will provide valuable information for the design of novel drugs for pharmacological therapies.As a central player of the canonical NO-sGC-cGMP pathway, sGC controls important physiological functions such as smooth muscle relaxation, platelet aggregation, and hemostasis NO is formed via two primary pathways.

In particular, several specific genomic aberrations including 11q13 amplification and KIT aberrations have been identified in acral melanomas.

The hisCGH combined with analyses of clinical parameters are a powerful approach to identify genomic loci that have significant impact on the clinical outcome of melanoma patients.

Those observations lead to the speculation that NUAK2 has more profound effects on cell migration resulting in worsening relapse-free survival of acral melanoma patients as suggested by both a migration assay and a wound healing assay [UV irradiation is one of the major causes of cutaneous melanomas, but acral and mucosal melanomas are protected from exposure to UV irradiation due to their anatomical locations. Thus, the molecular pathogenesis of acral and mucosal melanomas should be different from that of cutaneous melanomas arising from sun-exposed areas such as Non-CSD melanomas, and causes other than UV irradiation, such as reactive oxygen species (ROS), may play an important role in the melanomagenesis of acral and/or mucosal melanomas.

To get more valuable information from the mitochondria, we sequenced the complete mitochondrial genomes of BPH and SBPH. These two planthoppers were infected with two different functional Wolbachia (intracellular endosymbiont) strains (wLug and wStri). Since both mitochondria and Wolbachia are transmitted by cytoplasmic inheritance and it was difficult to separate them when purified the Wolbachia particles, concomitantly sequencing the genome of Wolbachia using next generation sequencing method, we also got nearly complete mitochondrial genome sequences of these two rice planthoppers. After gap closing, we present high quality and reliable complete mitochondrial genomes of these two planthoppers.N. lugens (BPH) and L. striatellus (SBPH) are 17, 619 bp and 16, 431 bp long with A + T contents of 76.95% and 77.17%, respectively. Both species have typical circular mitochondrial genomes that encode the complete set of 37 genes which are usually found in metazoans.

The large non-coding fragment (the A+T-rich region) putatively corresponding responsible for the control of replication and transcription of mitochondria contained a variable number of tandem repeats (VNTRs) block in different natural individuals of these two planthoppers. Comparison with a previously sequenced individual of SBPH revealed that the mitochondrial genetic variation within a species exists not only in the sequence and secondary structure of genes, but also in the gene order (the different location of trnH gene).The mitogenomes of The mitochondrial genome arrangement pattern found in planthoppers was involved in rearrangements of both tRNA genes and protein-coding genes (PCGs). Different species from different genera of Delphacidae possessing the same mitochondrial gene rearrangement suggests that gene rearrangements of mitochondrial genome probably occurred before the differentiation of this family.

By transmitting virus diseases [Wolbachia[Wolbachia strains, we also obtained nearly the complete mitochondrial genomes of BPH and SBPH. The Wolbachia strain wStri infecting SBPH can induce complete Cytoplasmic Incompatibility (CI), a reproductive modification that typically results in embryonic lethality between crosses of infected males and uninfected females. On the other hand, the Wolbachia strain wLug infecting BPH cannot induce CI at all.The brown planthopper (BPH), diseases and causdiseases . These tWolbachia which caWolbachia,24. WhiltrnH gene) were verified using natural populations. In addition, comparing mitochondrial genome of SBPH sequenced in this study with a previously sequenced individual revealed a remarkable variability between these two individuals.After gap-closing, the complete mitochondrial genomes of these two most important rice piercing and sucking type pests, BPH and SBPH were determined. We analyzed the nucleotide composition, codon usage and genomic rearrangement of these two mitochondrial genomes and compared them with mitochondrial genomes of other hemipteran species. Some special characteristics of mitochondria of these two planthoppers in \u2018A + T\u2019 rich regions; location of N. lugens (BPH) mtDNA and another scaffold containing 3 contigs of L. striatellus (SBPH) were identified in the assemblage of the wLug and wStri genome which were reported so far. The unusual length of the mitochondrial genome in N. lugens is partly due to a long putative control region and a long repeat region containing three repeats of trnC gene of BPH, trnS2 (UCN) of SBPH which harbor a simple loop in the dihydrouridine (DHU) arm and trnH of SBPH could have a loop-stem structure like trnT of BPH that forms a loop is found in many Hemiptera [trnS1 (AGN) has a completed loop-stem structure while that of trnS2 (UCN) has a loop. In contrast, the trnS1 (AGN) has a loop and trnS2 (UCN) has a completed loop-stem structure in previously reported SBPH [trnH gene of SBPH which formed a weak loop-stem structure of the T-arm (T\u03a8C) in this study possessed a stable loop-stem structural of the T-arm (T\u03a8C) in previous study [All of the tRNA genes have the typical cloverleaf secondary structure, except for emiptera ,18,27-30emiptera .

They are located between trnL1 (CUN) and an A+T-rich region, separated by trnV.The length of all tRNA genes ranged from 56 bp for trnC-trnW and nad6-trnP-trnT) associated with tRNAs and PCGs were found in both of BPH and SBPH . But the most striking feature was the different locations of the trnH gene in two individuals of SBPH. The trnH gene is located between nad5 and nad4 genes in this study just as in all other hemipteran species sequenced so far, but Song and Liang (2009) previously reported that this tRNA gene is located between nad4L and nad6 genes . This feature is common in hemipteran insects [The mtDNAs of BPH and SBPH contain the full set of PCGs usually presented in animal mtDNA. Except for the Insects were the shortest in insects known so far. In fact, the longest atp8 gene (228 bp) was found in Bemisia tabaci (Hemiptera: Aleyrodidae) [Pachypsylla venusta) [Lymantria dispar) [atp8 gene had a length of about 160 bp. Taking into account the length of atp8 gene of planthoppers discovered in this study, it seems that the length distribution of atp8 gene in Hemiptera was wider (From 99 bp to 228 bp) than that of all other orders of insects reported so far. The sequence alignment of atp8 gene with other insects revealed that nearly 60 bp length of sequence in the 3\u2032end of this gene was lost in these two planthoppers. Does the short length of this gene change the structure of its encoded protein? Does length change of this gene alter the functions or efficiency of this gene?

These two extreme A+T content species were inferring gene arrangement [The composition of the majority strand (J-strand) of SBPH mtDNA is A = 7099 (43.2%), T = 5581 33.97%), G = 1527 (9.29%) and C = 2224 (13.54%). The composition of the J strand of BPH mtDNA is A = 7393 (41.96%), T = 6165 (34.99%), G = 1661 (9.43%) and C = 2400 (13.62%). Similarly to most hemipteran insects, the nucleotide compositions of the two planthopper mitogenomes are significantly biased toward A and T . Comparing with 48 mitochondrial genomes of hemipteran species, we found that there is considerable variation in base composition among different hemipteran species: ranging from 68.9% to 0.2765 (Lycorma delicatula) with the BPH and SBPH mtDNA exhibiting a slight different AT-skew (0.0909 for BPH and 0.119171 for SBPH). The GC-skews of hemipteran species vary from \u22120.2827 (Acyrthosiphon pisum) to 0.2086 (Neomaskellia andropogonis) with the BPH and SBPH mtDNAs exhibiting very similar GC-skew (\u22120.1826 for BPH and \u22120.1842 for SBPH). Similarly, the AT/GC-skew values exhibit different ranges among three suborders: AT-skew: Heteroptera, 0.0642 - 0.2181,\u2009Sternorrhyncha,\u2009-0.1812\u2009- 0.0956, Auchenorrhyncha, 0.0623\u2009-T\u20090.2765;\u2009GC-skew:\u2009Heteroptera,\u2009-0.2656\u2009-(\u22120.0965),\u2009Sternorrhyncha,\u2009-0.2810\u2009-\u20090.2086,\u2009Auchenorrhyncha,\u2009-0.2827 - (\u22120.0783).The hemipteran AT-skews vary from \u22120.1812 of Sternorrhyncha, all species of Aleyrodidae exhibit converse AT/GC-skew values Figure\u00a0 as descrrrnL gene and rrnS gene with the entire mitochondrial genome, PCGs show more significant positive correlation (R2 = 0.9674) than rrnL gene (R2 = 0.8873) and rrnS gene (R2 = 0.7189) , complete trnH gene (62 bp), two intergenic nucleotides and a portion of nad4 gene (96 bp). All sequenced individuals have an identical sequence of the trnH gene which was the same with that of the mitochondrial genome of SBPH sequenced in this study. Considering the low probability of many different sites in the trnH gene related sequences caused by PCR or sequencing, we still cannot exclude the possibility that some sporadic individuals of SBPH possessing the same location of trnH gene as previous study exist in some special regions in China. Anyway, according to the mutation sites of all sequences of the region compassing trnH gene, 16 haplotypes of the sequence were identified were observed in natural populations and one ATP synthase gene (atp8). Because of the different locations of trnH gene, positions of the start codon of nad5 and nad6 genes and the end codon of nad4 and nad6 genes had been changed. Comparing the region (from nad5 to nad6) of mitochondrial genomes of SBPH with that of previous study, we found the differences were 57 bp deletion in the front of nad5 gene, 21 bp deletion at the end of nad4 gene and 84 bp insert in the front and 55 bp deletion at the end of nad6 gene. Furthermore, there also existed 21 bp absent in the nad2 gene and 60 bp absent at the end of atp8 gene of mitochondrial genome of these two SBPH, the other eight PCGs and two ribosomal RNA genes represented significant difference in the evolution rates showed the fastest mutation rate among these genes. The mutation rates of the other PCGs ranged from 0.0022 to 0.0076. The evolution rate of rrnS gene (0.8%) was five times faster than rrnL gene (0.16%). In general, except the trnH and two trnS genes, the other tRNA genes were conserved (only few of them have single variant site).Excluding five length distinct genes detected in the control region might provide additional genetic markers for studying population genetics, individual difference and phylogeographics of planthoppers. The comparative analyses of two sequenced mitochondrial genomes of SBPH revealed that rearrangements of genes in the mitochondrial genome could have occurred in the same species. On account of the different locations of trnH gene, the start and end codon of its neighboring genes had been changed. Even the same tRNA gene (e.g. trnS1 (AGN) and trnS2 (UCN) genes) could form different secondary structures in these two different individuals of SBPH. All these characteristics reveal that great divergence of mitochondrial genome could occur in different individuals of a species.The rearrangement of mitochondrial genome of planthoppers reported in this study adds more examples of the rearranged pattern of genes in the mitochondrial genomes of hemipteran insects studied so far. The fact that the rearrangement was conserved in Delphacidae suggests that gene rearrangements of mitochondrial genome probably occurred before the differentiation of this family. Compared with other hemipterans and other insects, the extreme short lengths of Laodelphax striatellus and Nilaparvata lugens for mitochondrial genome sequence were collected in China. Other natural populations which were used to validating location of trnH of SBPH and detecting the variable number of tandem repeats (VNTRs) in control regions of BPH and SBPH were collected in different locations of China generated from the PCR-free random shotgun-sequencing libraries of average insert size 500 bp, one scaffold composed of three contigs of mitochondrial genome of SBPH and one scaffold composed of four contigs of mitochondrial genome of BPH were generated were determined based on alignments and secondary structures of rRNA sequences of other hemipteran species. The boundaries of the ribosomal rrnL gene were assumed to be delimited by the ends of the trnL1 (CUN) and trnV. The 3\u2032 end of rrnS gene was assumed to be delimited by the start of trnV while the 5\u2032 end was determined through comparison with orthologous genes of other hemipteran species sequenced so far. The base composition, the Relative Synonymous Codon Usage (RSCU) values of BPH and SBPH were calculated with MEGA 4 program [After finished the gap closing work, we annotated the mitochondrial genomes of BPH and SBPH. All PCGs were identified by ORF Finder implemented at the NCBI website with the invertebrate mitochondrial genetic codes. Finally pair-wise comparisons with orthologous proteins from other hemipteran insects were performed to better define the limits of PCGs. The transfer RNA (tRNA) genes were identified using both of the tRNAscan-SE and ARWE program .trnH rearrangement types really exist in natural populations, we sequenced a region of mitochondrial genome encompassing the trnH gene from 309 individuals of SBPH which were collected from 15 natural populations and also checked the Wolbachia infection status of each individual to calculate the frequency of each haplotype of the sequence of this region.

The molecular mechanism by which neem leaf regulates female fertility remains poorly understood. Animal studies suggest that aqueous neem leaf extract (NLE) induces reactive oxygen species (ROS) - mediated granulosa cell apoptosis. Granulosa cell apoptosis deprives oocytes from nutrients, survival factors and cell cycle proteins required for the achievement of meiotic competency of follicular oocytes prior to ovulation. Under this situation, follicular oocyte becomes more susceptible towards apoptosis after ovulation. The increased level of hydrogen peroxide (H2O2) inside the follicular fluid results in the transfer of H2O2 from follicular fluid to the oocyte. The increased level of H2O2 induces p53 activation and over expression of Bax protein that modulates mitochondrial membrane potential and trigger cytochrome c release. The increased cytosolic cytochrome c level induces caspase-9 and caspase-3 activities that trigger destruction of structural and specific proteins leading to DNA fragmentation and thereby oocyte apoptosis. Based on these animal studies, we propose that NLE induces generation of ROS and mitochondria-mediated apoptosis both in granulosa cells as well as in follicular oocyte. The induction of apoptosis deteriorates oocyte quality and thereby limits reproductive outcome in mammals.Neem ( Azadirachta indica L.) has been considered as one of the most important medicinal plants worldwide.

(3) Finally, is CRP a cardiovascular drug target?This special issue comprises four review articles and three research articles that reflect the ongoing controversy over the subject. The review articles discuss CRP as a cardiovascular risk marker, CRP in animal models, CRP in its native and nonnative conformation, and CRP in human arteriosclerosis. The research articles deal with CRP as a cardiovascular risk marker in non-ST elevation acute coronary syndrome and with CRP as a drug target. The discussion climaxes in two research articles describing the use of CRP specific antisense oligonucleotides (ASOs) for the treatment of cardiovascular disease in animal models. The conclusions are indeed contradictory. When looking at the two articles, three general points may have to be taken into consideration. (1) Is the statistical power of the animal experiments adequate to draw definitive conclusions? (2) Are there off-target effects of the ASOs that may confound the results?

We asked how structured and free-text narrative EMR data should be combined to improve epidemic surveillance for acute respiratory infections (ARI).Eight previously characterized ARI case detection algorithms (CDA) were applied to historical EMR entries to create authentic time series of daily ARI case counts (background). An epidemic model simulated influenza cases (injection). From the time of the injection, cluster-detection statistics were applied daily on paired background+injection (combined) and background-only time series. This cycle was then repeated with the injection shifted to each week of the evaluation year. We computed: a) the time from injection to the first statistical alarm uniquely found in the combined dataset (Detection Delay); b) how often alarms originated in the background-only dataset ; and c) the number of cases found within these false alarms (Caseload). For each CDA, we plotted the Detection Delay as a function of FAR or Caseload, over a broad range of alarm thresholds.CDAs that combined text analyses seeking ARI symptoms in clinical notes with provider-assigned diagnostic codes in order to maximize the precision rather than the sensitivity of case-detection lowered Detection Delay at any given FAR or Caseload.An empiric approach can guide the integration of EMR data into case-detection methods that improve both the timeliness and efficiency of epidemic detection.

The reduced IFN signature in RA patients following baminercept treatment is the first time outside of high dose steroid therapy that an IFN signature was decreased by a pharmacological treatment not targeting IFN itself. Taken together with the known effects of LTBR inhibition, these studies not only link the LTBR axis to IFN production in man, but also provide potential insight into the nature of the IFN signature.Two randomized phase IIb controlled studies of the effects of baminercept in rheumatoid arthritis were conducted. One study enrolled patients with an inadequate response to disease-modifying antirheumatic drug therapy (DMARD-IR) and the other involved patients with an inadequate response to tumor necrosis factor inhibition (TNF-IR) and an IFN score calculated and type II IFN (IFN\u03b3) and, furthermore, each IFN is capable in many contexts of inducing the expression of the other IFN class Elevated levels of type I IFN or an IFN-like inducing activity can be found in the sera of a subset of the SLE patients with a transcriptional IFN signature; however, in RA the results range from not detectable to low levels relative to SLE sera SLE patients with a high IFN signature tend to be lymphopenic In rodents, blockade of the LTBR system leads to lymphocytosis within several weeks most likely due to loss of high endothelial venule addressin expression and reduced entry into the lymph nodes and mucosal environments In mice, lymphocytosis following LTBR blockade results from elevated T and B cells counts Given the emphasis on plasmacytoid DC as the source of the IFN signature in SLE, we examined RNA levels in the blood of two known pDC markers, CLEC4C (BDCA2) and LILRA4 (ILT7). LILRA4 levels increased following baminercept treatment, yet CLEC4C levels were unchanged scoring system. Overall, baminercept was well tolerated was a multicenter, phase IIb, double-blinded, placebo-controlled study of RA patients who lacked an adequate response to TNF-blocking therapy and had discontinued TNF blocking treatment for at least 90 days. The study dosed 114 patients with subcutaneous injections q2w of either placebo (38) or baminercept 200 mg (76). This study was terminated early due to poor efficacy in the DMARD-IR study; however, 81 patients completed the 3 months of dosing and another 15 patients received at least 2 months of treatment.

Ninety-three patients underwent all of preoperative CAG, real-time graft assessment and postoperative CAG with a total of 93 grafts anastomosed to the right coronary artery. Severity of coronary artery stenosis was evaluated by CAG. The size of target right coronary artery was measured by ultrasonography in the operative field. Parameters about graft flow were obtained from flow velocity curve in all the graft. The grafts were divided into two groups: patent grafts and failing grafts . All factors were compared in these two groups and evaluated by logistic analysis and receiver operating characteristic (ROC) curve analysis.The overall patency as measured by postoperative CAG was 94.6% (88/93). There were 7 failing grafts including 5 occlusion and 2 competitive slow flow. Logistic regression analysis revealed that the percentage of graft size measured by ultrasonography divided by the size of the right coronary artery (graft-RCA size mismatch) and the pulsatility index (PI) were independent predictors of early graft failure . ROC curve analysis revealed that graft-RCA size mismatch > 2.08 and PI > 4.55 were predictors of graft failure.In this series, epigraftic ultrasonography depicted graft flow clearly.

The participants\u2019 satisfaction with the therapy was assessed using the OnyCOE-t questionnaire.Of the 70 nails analysed, the patterns of infection were classified as proximal subungual onychomycosis (49%), distal lateral subungual onychomycosis (47%), white superficial onychomycosis (3%), and total dystrophic (1%). Almost half of all participants (45%) had onychomycosis affecting only one toenail. Only 23% of participants had previously treated the infection and the mean duration of infection was 10 years and 3 months.Nails with superficial onychomycosis (n=2) were found to have 86% clearance of infection after four months. One third of all nails (n=11) with distal lateral subungual onychomycosis and 50% (n=17) of nails with proximal subungual onychomycosis demonstrated a zone of clearance at the proximal nail plate tissue, suggesting a fungistatic effect of the eucalyptus oil.Topical eucalyptus oil is more effective as an antifungal treatment for fungal infected toenails without nail matrix infection. Eucalyptus oil may provide an acceptable and cheaper alternative to prescription topical antifungal agents, for people with white superficial onychomycosis or distal lateral subungual fungal nail infections."} +{"text": "UGT1A1*28 was not questioned in our study.There is an error in the second sentence in the third paragraph of the \u201cGenetic differentiation and haplotype diversity for DMET Plus markers\u201d section of the Results.

Thus, 2785 abstracts were screened for initial eligibility to identify studies conducted in eastern Africa. We identified 696 relevant abstracts of studies conducted in eastern Africa. We conducted further screening for studies reporting on alcohol use and identified 285 abstracts for full article review. Of these 285 abstracts for full article assessment, we could not access six full articles, 11 were review articles and five were conference posters.Thus, we reviewed 263 full-text papers and identified 56 eligible for inclusion in the review. The main reason for exclusion was that the paper did not report information on alcohol use from the target population, that is, young people aged 15\u201324 years, or that young people were included but we could not separate the prevalence in this age group from that in older people , and two were case\u2013control studies.

These showed similar levels as found for reported current alcohol use. Three studies were from the general population with a pooled prevalence of 30% (95%CI: 27\u201333%) and one from university students . One study reported gender-specific prevalence; it was high among males (34% vs. 9%(IQR: 9\u201320%) in the general population, 28% (IQR: 13\u201344%) vs 19%(IQR: 7\u201332%) among healthcare service attenders, 60% (IQR: 56\u201363%) vs. 41% (IQR: 24\u201358%) in secondary schools, and 43% vs. 28% in a university. There was no significant heterogeneity in studies conducted among university students except one study among female university students among female bar workers and 47% (95%CI: 40\u201353%) among male sex workers. Median prevalence in the general population was 3% (IQR: 1\u201315%); two of the studies in the general population were from Ethiopia and showed low levels of problem drinking (1\u20133%), but a study from Tanzania reported a rather high median prevalence of 15% (95%CI: 10\u201320%).et al. et al. et al. In this review, eight studies reported problematic drinking, two studies applied AUDIT, and six (13%) used CAGE to screen for problem drinking; two of the studies that applied CAGE and one study that applied AUDIT did not report scores according to age groups and female sex workers (66%) and lower among the general population and primary school students. Few studies reported alcohol use in the last year, and median prevalence in the general population was 29%. Reported current alcohol use was highest among male sex workers (69%), followed by the university students (33%), and was lowest in the general population and secondary school students with the exception of one study in the Seychelles that reported a high prevalence of 61%. Problem drinking was highest among groups known to engage in high-risk behaviours (such as bar workers and sex workers). Generally, reported alcohol use across all definitions of use was highest among groups known to engage in high-risk behaviours, followed by university students. Individuals attending healthcare services and general populations and secondary school students reported the lowest prevalence. Studies included in this review were of good quality; however, about two-thirds employed face-to-face interviewing approaches, an approach prone to social desirability bias that could lead to underreporting of alcohol use.vs. students vs. sex workers). We also attribute these variations to social influence and peer pressure ; it is, however, not widely used for the assessment of AUD among young people in general populations. In our review, only two studies used the internationally recommended AUDIT alcohol screening questionnaire (Mbatia et al. et al. The use of effective and validated instruments for the screening and assessment of alcohol use is essential to guide research and is important for the design and evaluation of interventions. AUDIT is validated and recommended by WHO for use at the primary healthcare settings and for the assessment of AUD in developing countries (Saunders Reported alcohol use among young people in eastern Africa is common and varies between different populations. The prevalence of AUD was highest among populations known to engage in high-risk sexual behaviours, but was also high among students in some of the studies. The studies reviewed lacked data about initiation and persistence of alcohol use, and little information was available about risk factors associated with alcohol use, and AUD. Notably, only few of the studies reviewed used internationally recommended and validated screening questionnaires such as AUDIT. Future epidemiological studies on alcohol use among young people should apply these questionnaires to facilitate comparison. However, such questionnaires have not been evaluated among young people in Africa, and studies closing this knowledge gap are therefore also required. Future studies should also determine factors responsible for initiation, persistence, and patterns of use in preparation for potential interventions. There is an urgent need of targeted interventions for groups of young people with a particularly high risk of alcohol use and AUD such as college students and young sex workers."} +{"text": "Background Exposure to high levels of Aluminium (Al) leads to a neurodegenerative disorders , which may be mediated through over generation of free radicals.

The nature of the association of IBD with IHD is uncertain. We aimed to define the extent and direction of that association.This retrospective cohort study examined records from patients aged \u2265 15 years with IBD from 1987\u20132009 (n = 19163) who were age and gender matched with patients without IBD (n = 75735) using the General Practice Research Database. The primary outcome was the hazard ratio for IHD.A higher proportion of IBD patients had a recorded diagnosis of IHD ever, 2220 (11.6%) compared with 6504 (8.6%) of controls. However, the majority developed IHD prior to IBD diagnosis (1404 (63.2%) of IBD cases and 3090 (47.5%) of controls). There was increased IHD incidence in the first year after IBD diagnosis. Mean age at IHD diagnosis was statistically similar across all IBD groups apart from for those with Ulcerative Colitis (UC) who were slightly younger at diagnosis of angina compared to controls and coronary heart disease . Of those developing IHD following IBD diagnosis, UC patients were at higher risk of IHD (unadjusted HR 1.3 (95% CI 1.1\u20131.5), p<0.001) or MI (unadjusted HR 1.4 (95% CI 1.1\u20131.6), p = 0.004).Although IHD prevalence was higher in IBD patients, most IHD diagnoses predated the diagnosis of IBD. This implies a more complex relationship than previously proposed between the inflammatory responses associated with IHD and IBD, and alternative models should be considered. The inflammatory bowel diseases (IBD) ulcerative colitis (UC) and Crohn\u2019s Disease (CD) are disorders of uncertain origin. In both UC and CD, an exaggerated immune response to unknown antigens is evident and a nuThere is a well-described association between rheumatoid arthritis (RA) and increased cardiovascular mortality, mainly as a result of ischaemic heart disease (IHD)., 10 AtheThere are sufficient shared characteristics to the inflammatory responses seen in IBD and RA to hypothesise that the recognized association between RA and IHD might also exist for IBD and IHD. Previous cohort studies have examined the risk of IHD in patients with IBD and have variously found no effect, or a slihttp://www.cprd.com/home/) between 1987 and 2009. For each subject with IBD, a further 4 subjects were identified and matched for age and sex but without IBD. All cohort members were followed from the start date (i.e. the date their GPRD record began) until the earliest occurrence of one of the following endpoints: recorded code of IHD, death, date of exit from GPRD registered GP practice, or end of study period (31.12.2009). Patients with less than (1) 2 years up-to-standard enrolment with the GP or (2) 1 year of computerized prescription history or (3) no health contacts during their complete period of follow-up were excluded from the cohort. Patients whose date of death or date of transfer out of a GPRD-registered practice preceded date of IBD diagnosis were excluded from the cohort. Patients <15 years of age at entry were excluded.The study population for this retrospective cohort study consisted of around 2.1 million male and female patients with an active registration at practices contributing to the General Practice Research Database , or Crohn\u2019s Disease (CD), or inflammatory bowel disease (not otherwise specified) (IBD (nos)) recorded on the database since 1987; patients with ICD-10 Read Codes (K50-K51) records of both UC and IBD were coded as UC; CD plus IBD were coded as CD; individual records which included both UC and CD were included only in analyses of IBD (nos). Prevalent IBD cases on 01.01.1987 were excluded. The index date was defined as the date of first recording of IBD. Lifetime IBD severity was determined using an algorithm based on IBD drug-use and surgical intervention (colectomy/stomata) developed by team members with clinical and research expertise in IBD.Age, sex and practice matched controls were allocated the same index date as their matched case. Because IHD has not been subjected to the same specific validation studies as IBD, our operational definition was developed using advice from clinicians with special interest in cardiovascular disease to include the following: Read Codes for IHD Coronary Heart Disease (CHD) was considered for the purpose of this study to be synonymous with IHD and Read Codes for coronary heart disease (including coronary artery disease) were included.Data was accessed within limits set out by the Medical Research Council licence agreement for academic access with Medical Research Ethics Committee ethical approval. The proposal was approved by the Independent Scientific Advisory Committee of the GPRD (protocol number 10_003).a priori hypothesis, that IHD followed IBD, was conducted on a subset which included cases of IHD following IBD and their associated matched controls (COHORT B: n = 77540).Descriptive analysis of baseline characteristics and exploration of the direction of association between IBD and IHD was conducted using the whole cohort of patients aged over 15 years . Subsequent analysis of the The relative risks of ischaemic heart disease (IHD) and its sub-entities myocardial infarction (MI) and angina), as well as CHD were estimated as hazard ratios (HRs) for patients with IBD compared to non-IBD patients, using Cox proportional hazard models. Models were subsequently adjusted for age, gender, socio-economic status , comorbidity and concomitant drug use, IBD disease severity, and smoking status. We carried out both forward and backward stepwise covariate selection within the cox proportional hazard model. All covariates were initially included with entry testing based on the significance of the score statistic, and removal testing based on the probability of a likelihood-ratio statistic based on conditional parameter estimates. Models were tested for interactions between fitted variables. Precision of estimates is reported using 95% confidence intervals. Data management was performed using Stata 10IC. Cox regression proportional hazard computations and Kaplan-Meier survival analysis were conducted using SPSS 21.Data were examined from electronic primary care records from 221 general practices across the UK from patients with a first diagnosis of IBD recorded from 1st January 1987 to 31st December 2009 . FollowiOf 19163 IBD cases, a total of 2220 (11.6%) had an IHD diagnosis ever, compared with 6504 (8.6%) of those without IBD. Of these IHD diagnoses, 4494 (51.5%) occurred prior to IBD diagnosis (1404 (63.2%) of IBD cases and 3090 (47.5%) of controls) . AccordiA total of 17358 patients were excluded from subgroup analysis where IHD preceded IBD or, for controls, the matched IBD date . Subset In order to examine the subset in a way that was consistent with previous research, the inciThis is the first study to fully examine both the strength and direction of association between development of ischaemic heart disease (IHD) and IBD. An increased incidence of IHD, angina, MI, and CHD diagnoses was seen in the first year after IBD diagnosis but the mean age of diagnosis comparing IBD cases with non IBD cases was not statistically different, apart from those with Ulcerative Colitis (UC) who were slightly younger at diagnosis of angina and coronary heart disease. Of those developing IHD following an IBD diagnosis, patients with UC were at slightly higher risk of a diagnosis of IHD or MI although results were not significant after adjustment for the role of covariates. Most notably, we found that although overall prevalence of IHD was higher in those with IBD, in the majority of cases the diagnosis of IHD actually predated that of IBD.This is the largest British cohort study to examine this issue. It used the General Practice Research Database which is an appropriate and reliable resource for IBD research, having been used for at least 19 studies published in peer-reviewed journals since 2000. The diagnostic reliability of IBD diagnosis and the year of IBD diagnosis in the GPRD has been confirmed in a recent validation study. Other GPAs others have highlighted , there iThe temporal relationship between IBD and IHD may be weakened by differences with which the diagnosis of each is recorded in the GPRD. IHD is a diagnosis made in the majority of cases fairly soon after the onset of symptoms, because of an event requiring admission to hospital . Nevertheless, among those with stable angina, nearly half have symptoms for 6 months or more before diagnosis. For IBD It is possible that IHD cases may have been missed or incorrectly coded within GPRD. Unrecorded diagnoses are increasingly unlikely within UK general practice due to policy and fiscal incentives to assess, monitor and treat cardiovascular disease, althoughThis is the first known study to examine the temporal relationship between IHD and IBD and we found that the majority of IHD cases predated IBD diagnosis. Previous research has predominantly focused attention on incident cases of IHD occurring at or after diagnosis of IBD. It is notable that the overall risk of prevalent (i.e. whole cohort) IHD was almost identical to a recent Danish study at 2.1 IBy identifying and quantifying both the strength and direction of association between IBD and IHD, this study provides important insights into the burden of IHD in the IBD population. This is relevant for basic scientists exploring the temporal causal pathway, and clinicians who should be aware of the risks of IHD in patients with IBD and vice versa.S1 FigTotal number of patients showing time from IBD diagnosis (T0) to the first cardiovascular event according to IBD type and age categories.(TIF)Click here for additional data file.S2 FigTotal number of patients showing time from IBD diagnosis (T0) to the first cardiovascular event according to IBD type and gender categories.(TIF)Click here for additional data file.S3 FigTotal number of patients showing time from IBD diagnosis (T0) to the first Coronary Heart Disease (sub-group of CVD) event according to IBD type.(TIF)Click here for additional data file.S4 FigTotal number of patients showing time from IBD diagnosis (T0) to the first Ischaemic Heart Disease (sub-group of CVD) event according to IBD type.(TIF)Click here for additional data file.S5 FigTotal number of patients showing time from IBD diagnosis (T0) to the first Angina (sub-group of CVD) event according to IBD type.(TIF)Click here for additional data file.S6 FigTotal number of patients showing time from IBD diagnosis (T0) to the first Myocardial Infarction (sub-group of CVD) event according to IBD type.(TIF)Click here for additional data file.S7 FigTotal number of patients showing age at onset of Cardiovascular Disease according to IBD type.(TIF)Click here for additional data file."} +{"text": "Our data provides first evidence that the genetic factors associated with pigmentation traits are risk loci of UM susceptibility.While the role of genetic risk factors in the etiology of uveal melanoma (UM) has been strongly suggested, the genetic susceptibility to UM is currently vastly unexplored.

The complete list of selected variants with association information from prior studies is in For the genotyping of 29 selected variants, the highly multiplexed Sequenom MassARRAY system was used according to the manufacturer\u2019s protocol. Quality control (QC) measures included duplicates (8 per each 384-well plate) and non-template controls (2 per plate) resulting in >99% observed concordance with no evidence of cross-contamination. Post-genotyping filtering criteria were as follows: exclusion of SNPs with minor allele frequency (MAF) <5%, exclusion of SNPs with a call rate <95%, exclusion of samples with a call rate <95%, and exclusion of SNPs with significant departure from Hardy-Weinberg equilibrium (p\u2009<\u20090.001). The filtering steps excluded one variant with MAF\u2009<\u20090.05, resulting in genotype information on 28 variants for 272 UM patients and 735 matched controls.2 tests (1 degree of freedom). All analyses were performed in PLINK2\u2009=\u20091) determined from European ancestries in the recent data release of 1000 Genomes Project Phase 3 (October 2014), as indicated in The association of UM risk with the selected 29 common genetic variants in the analysis of 272 cases and 1782 controls was estimated as odds ratios (OR) with 95% confidence intervals (95% CI), using unconditional logistic regression in an additive model where two copies of the minor allele have twice the effect of one copy. The genotype model (separate indicators for heterozygotes and rare homozygotes), dominant model (indicator for heterozygotes and rare homozygotes combined) and recessive model (indicator for homozygotes) were also assessed but not reported as they presented no significant additional information not captured by the additive model. All models were adjusted for continuous age at diagnosis (cases) or at the time of inclusion in the study (controls) and gender. Deviations of the genotype frequencies in the controls from those expected under Hardy-Weinberg equilibrium were evaluated by \u03c7IMPUTE2 was used for imputationThe imputed variants were tested for UM association using logistic regression implemented by the SNPTEST software under an additive model. Genotype uncertainties from imputation were accounted for in the model using genotype dosages. Notably, there were a number of variants comparably significant to our top genotyped associations .

Moreover, these genes had diverse endogenous expression patterns in switchgrass during seed germination, vegetative growth, flower development, and seed formation. Interestingly, several members of the ERF and DREB families were found to be highly expressed in plant tissues where active lignification occurs. These results provide vital resources to select candidate genes to potentially impart tolerance to environmental stress as well as reduced recalcitrance. Overexpression of one of the ERF genes (PvERF001) in switchgrass was associated with increased biomass yield and sugar release efficiency in transgenic lines, exemplifying the potential of these TFs in the development of lignocellulosic feedstocks with improved biomass characteristics for biofuels.The APETALA2/ethylene response factor (AP2/ERF) superfamily of transcription factors (TFs) plays essential roles in the regulation of various growth and developmental programs including stress responses. Members of these TFs in other plant species have been implicated to play a role in the regulation of cell wall biosynthesis. Here, we identified a total of 207 AP2/ERF TF genes in the switchgrass genome and grouped into four gene families comprised of 25 AP2-, 121 ERF-, 55 DREB (dehydration responsive element binding)-, and 5 RAV (related to API3/VP) genes, as well as a singleton gene not fitting any of the above families. The ERF and DREB subfamilies comprised seven and four distinct groups, respectively. Analysis of exon/intron structures of switchgrass AP2/ERF genes showed high diversity in the distribution of introns in AP2 genes versus a single or no intron in most genes in the ERF and RAV families. The majority of the subfamilies or groups within it were characterized by the presence of one or more specific conserved protein motifs. Panicum virgatum) is an outcrossing perennial C4 grass known for its vigorous growth and wide adaptability and, hence, is being developed as a candidate lignocellulosic biofuel feedstock is a large group of regulatory protein families in plants that are characterized by the presence of one or two conserved AP2 DNA binding domains. AP2/ERF TFs are involved in the transcriptional regulation of various growth and developmental processes and responses to environmental stressors. The AP2 domain is a stretch of 60\u201370 conserved amino acid sequences that is essential for the activity of AP2/ERF TFs have been suggested to be associated with the regulation of cell wall biosynthesis in some tissues Arabidopsis AP2/ERF TFs were excluded from our subsequent analysis.We used representative genes from appropriate rice gene families as the basis to search for orthologs in switchgrass. The amino acid sequences of AP2 domain-containing rice genes represented three families: AP2 (Os02g40070), ERF (Os06g40150), and RAV (Os01g04800). These proteins were used to query the derived amino acid sequences of all switchgrass AP2/ERF TFs using tblastn against the switchgrass EST database . The exon\u2013intron organizations in these genes were visualized by the gene structure display serverThe genomic and coding DNA sequences of the identified AP2/ERF TFs were retrieved from the Phytozome (The transcript data for the AP2/ERF superfamily TFs were extracted from the publicly available switchgrass gene expression atlas (PviGEA)Arabidopsis AtSHN2 (At5g11190) and rice OsSHN (Os06g40150) was identified by tblastn or blastp against the switchgrass EST database or draft genome (Phytozome v1.1 DOE-JGI) followed by cluster and multiple sequence alignment analysis to discriminate the most closely related gene for cloning. For construction of overexpression cassette, the open reading frame (ORF) of PvERF001 was isolated from cDNA obtained from ST1 clonal genotype of \u2018Alamo\u2019 switchgrass using gene-specific primers flanking the ORF of the gene and cloned into pANIC-10A expression vector by GATEWAY recombination and watered three times per week, including weekly nutrient supplements with 100\u2009mg/L Peter\u2019s 20-20-20 fertilizer. Transgenic and non-transgenic control lines were propagated from a single tiller to produce three clonal replicates for measuring growth parameters and quantitative [pyrolysis molecular beam mass spectrometry (py-MBMS)] analysis of lignin content was performed as previously described particle size and sugar release efficiency was determined via NREL high-throughput sugar release assays on extractives- and starch-free samples with least significant difference (LSD) procedure was used while PROC TTEST procedure was used to examine the statistical difference between the expression of target genes in transgenic vs non-transgenic lines using SAS version 9.3 . Pearson\u2019s correlation coefficient to determine the relationship between relative transcript levels and growth parameters was calculated by SAS.Arabidopsis along with the presence of conserved B3 domain suggest that these proteins might be categorized as putative AP2/ERF TFs. The characteristic features of these genes are summarized in Table S2 in Supplementary Material. The amino acid sequences of AP2/ERF TFs showed wide variation in size (ranging from 119 to 666 amino acids) and sequence composition. Twenty-two of these TFs contained two AP2 DNA-binding domains and hence were classified under AP2 family. Five of the AP2/ERF proteins had a B3 conserved domain at the C-terminus in addition to the common AP2 domain, and these genes were grouped into the RAV family. Three of the remaining 180 proteins, namely PvERF049, PvERF160, and PvERF177 with a single AP2 domain, which is more similar to the amino acid sequences of AP2 domains in the AP2 family TFs, were also grouped under the AP2 family. Moreover, one AP2/ERF protein showed a distinct AP2 domain different from all other switchgrass AP2/ERF proteins but with higher shared sequence similarity with the previously identified genes in rice and Arabidopsis. The remaining 176 proteins were grouped into ERF family, which was further subdivided into either one of two subfamilies (ERF and DREB) based on sequence similarity in the AP2 domain. The ERF subfamily members included 121 proteins while DREB had only 55 proteins .To confirm the classification and evaluate the sequence similarities between the switchgrass AP2/ERF TFs, a dendrogram was constructed by NJ method using the whole amino acid sequences of the proteins. The analysis showed distinct clustering of the proteins into specific groups and families as previously described in other species Figure . SpecifiTo complement the cluster analysis-based classification, the exon\u2013intron structures of AP2/ERF genes were evaluated. The schematic representations of protein and gene structures of switchgrass AP2/ERF superfamily are presented in Figure Analysis of amino acid sequence conservation in the whole proteins of AP2/ERF superfamily showed the presence of unique conserved motifs shared between proteins within families, subfamilies, or groups Figures . MoreoveGene ontology analysis of switchgrass AP2/ERF TFs, based on rice reference sequences, predicted candidate genes\u2019 molecular functions, putative roles in the regulation of diverse biological processes, and their cellular localization containing expression data for about 78,000 unique transcripts in various tissues was recently developed displayed increased expression level at radicle emergence whereas the other two (PvERF049 and PvERF203) showed increased expression at coleoptile emergence. The expression of the RAV genes and the singleton gene were apparently relatively less variable throughout the seed germination process revealed apparent differential expression pattern between the organs and different stages of vegetative development . Moreover, the expression pattern of AP2/ERF genes during reproductive development also showed differential expression between the reproductive tissues from the initiation of inflorescence meristem to the maturation of the seeds .PvERF95, PvERF98, PvERF101, and PvERF102) and one gene in group II (PvERF148) of the DREB subfamily showed highest expression in vascular bundles and internode tissues followed by internode portions where active lignification is expected and X showed the highest expression in the vascular bundles followed by youngest internode sections , one gene in group VI-L (PvERF088), and three genes in group VII had high expression in vascular bundles. Contrastingly, some genes in the ERF subfamily belonging to group V (PvERF001 and PvERF002) and VI (PvERF068) showed the highest expression in the basal fragments of the fourth internodes (E4) that is under less active lignification. Other genes including PvERF178 (VI); PvERF110 (VII), PvERF115 (VII), and PvERF164 (VII); and PvERF038 (IX) had notably high relative expression in roots than in other tissues. Compared to the ERF family genes, the expression of AP2 genes was highly diverse with some genes having high specificity to roots and vascular bundles. The expression of the two RAV genes analyzed was uniformly low throughout whereas the singleton gene was highly expressed in the LBs, LSH as well as the vascular bundles, and young internode sections and rice OsERF057 (OsSHN) in ERF subfamily group V, for overexpression analysis in switchgrass. This gene was selected since the expression of its Arabidopsis homolog in transgenic rice resulted in modified cell wall composition and the C-terminal motif (cm) specific to the Arabidopsis SHINE clade of TFs and OsERF012 and OsERF057 and tiller height (R\u2009=\u20090.73 at P\u2009=\u20090.06)] . However, no tangible difference was observed in the rate of leaf chlorophyll leaching between transgenic and the control lines (data not shown). Subsequently, we analyzed whether the changes in leaf morphology might be accompanied by changes in the expression level of genes in the cutin and wax biosynthesis pathway, in which none were observed . Moreover, overexpression of PvERF001 in transgenic switchgrass showed relatively reduced expression of some lignin (PvC4H and PvPAL), hemicellulose (PvCSLS2), and cellulose (PvCESA4) biosynthetic genes, as well as some of the transcriptional regulators (PvMYB48/59 and PvNST1) of cell wall biosynthesis . The total lignin content in R1 tillers determined by Py-MBMS of cell wall residues and in leaves determined by phloroglucinol\u2013HCl staining did not show sizeable difference between the transgenic and non-transgenic control lines . Similarly, analysis of the S/G lignin monomer ratio in transgenic lines did not significantly change as compared to that of the non-transgenic control line . However, significant improvement in glucose release efficiency was observed in lines 7 (10%) and 8 (16%) relative to the non-transgenic control line , and Populus (66). All three species along with switchgrass have a singleton in their genome. Consistent with the previous report in rice , also known as the cytokinin responsive factor (CRF) domain in Arabidopsis that is also shared by rice ERF genes belonging to same group in rice ERF subfamily displayed LWSY conserved motif (M21) at the C-terminal and thus may play similar roles. No information is available in the literature on some of the conserved motifs identified here including M8, M13, M14, M15, M17, and M24 , which might potentially be specific to switchgrass.AP2/ERF TFs that function as repressors or activators of specific target genes are distinguished by the presence of conserved motifs called repression domains (RD) that are highly conserved, or by the presence of activation domains which are generally less conserved , DREB , and AP2 genes during the initiation of seed germination as well as in vascular bundles and internode sections. Moreover, the observed robust expression of 14 DREB, 17 ERF, and 3 AP2 genes in tissues or organs undergoing active lignification but less robust expression in less lignified tissues (leaves) also supports this assertion , reduced lignification, and enhanced carbohydrate content (cellulose) in the wood of transgenic lines hinting that these TFs may indeed interact with the transcriptional machinery regulating cell wall biosynthesis (EjAP2-1) is an indirect transcriptional repressor of lignin biosynthesis via interaction with EjMYB1 TFs gene resulted in improved enzymatic saccharification efficiency via increased level of starch was expressed mainly in the abscission zone and functionally associated with the regulation of the pedicel abscission zone-specific transcription of genes including cell wall-hydrolytic enzymes required for abscission was proposed to have a native association with cell wall regulatory and biosynthetic pathways, yet this was not experimentally verified exhibiting reduction in plant height but increase in the number of tillers (Zhou et al., PvERF001 showing increased plant height but no difference in number of tillers. This suggests that ERF genes might functionally be highly diversified and PvERF001 may be part of a different pathway than we anticipated such as regulation of responses to biotic stress or other abiotic stress or regulation of cell elongation or division in coordination with the cytokinin pathway, with the latter perhaps explaining the observed increase in biomass and vegetative growth in transgenic lines.A recent study involving overexpression of rice homolog of PvERF001 highlight the potential of these TFs for improvement of bioenergy feedstocks.In summary, the expression profiling of the switchgrass AP2/ERF genes provides baseline information as to the putative roles of these genes and thus a useful resource for future reverse genetic studies to characterize genes for economically important bioenergy crops. With the current advancements in switchgrass research and establishment of efficient transformation system, this inventory of genes along with the information provided here could facilitate our understanding regarding the functional roles of AP2/ERF TFs in plant growth and development. Furthermore, it would aid in the identification of potential target genes that may be used to improve stress adaptation, plant productivity, and sugar release efficiency in bioenergy feedstocks such as switchgrass.

Interpreting XPD mutations in the context of available biochemical data led us to propose adverse effects on CDK-activating kinase (CAK) subunit of TFIIH and TFIIH-mediated functions as a relevant mechanism in preeclampsia. In order to gain deeper insight into the underlying biologic mechanisms involving TFIIH-mediated functions in placenta, we analyzed NER/transcription and global gene expression profiles of normal and preeclamptic placentas and studied gene regulatory networks.Preeclampsia is a significant cause of maternal and fetal mortality and morbidity worldwide. We previously reported associations between trichothiodystrophy (TTD) nucleotide excision repair (NER) and transcription gene mutations in the fetus and the risk of gestational complications including preeclampsia. TTD NER/transcription genes, XPD and XPB were consistently expressed from 14 to 40 weeks gestation while expression of TTD-A was strongly negatively correlated with gestational age. Analysis of gene expression patterns of placentas from a case-control study of preeclampsia using Algorithm for Reconstruction of Accurate Cellular Networks (ARACNE) revealed GTF2E1, a component of TFIIE which modulates TFIIH, among major regulators of differentially-expressed genes in preeclampsia. The basal transcription pathway was among the largest dysregulated protein-protein interaction networks in this preeclampsia dataset. Within the basal transcription pathway, significantly down-regulated genes besides GTF2E1 included those coding for the CAK complex of TFIIH, namely CDK7, CCNH, and MNAT1. Analysis of other relevant gene expression and gene regulatory network data also underscored the involvement of transcription pathways and identified JUNB and JUND (components of transcription factor AP-1) as transcription regulators of the network involving the TTD genes, GTF2E1, and selected gene regulators implicated in preeclampsia.We found high expression of TTD NER/transcription genes in normal human placenta, above the mean of their expression in all organs. Our results indicate that TTD NER/transcription genes are expressed in placenta during gestational periods critical to preeclampsia development. Our overall findings suggest that impairment of TFIIH-mediated function in transcription in placenta is a likely mechanism leading to preeclampsia and provide etiologic clues which may be translated into therapeutic and preventive measures. Preeclampsia is a complex disorder affecting about 7% of all pregnancies and a major cause of severe intrauterine growth restriction (IUGR) and preterm birth . Preecla6) recessive disorder and XPB in placenta compared to skin and other tissues.

This disorder has important metabolic effects in insulin resistance and lipolysis. The objective of this study was to explore transcriptional changes induced by GH in adipose tissue.Patients with acromegaly (n=9) or non-functioning pituitary adenoma (n=11) were prospectively observed from March 2011 to June 2012. The patients underwent clinical and metabolic profiling including assessment of HOMA-IR. Explants of adipose tissue were assayed ex-vivo for lipolysis and ceramide levels. Adipose tissue was analyzed by RNA sequencing (RNAseq).IGF1, IGFBP3) as well as several novel transcriptional changes, some of which may be important for GH signal regulation (PTPN3 and PTPN4) and the effect of GH on growth and proliferation. Several transcripts could potentially be important in GH-induced metabolic changes. Specifically, induction of LPL, ABHD5, ACVR1C could contribute to enhanced lipolysis and may explain the suggestive enhancement of adipose tissue lipolysis in acromegaly patients as reflected by glycerol release from the explants of the two groups of patients (p=0.09). Higher expression of SCD and TCF7L2 could contribute to insulin resistance. Expression of HSD11B1 was reduced and GR was increased, predicting modified glucocorticoid activity in acromegaly.There was evidence of reduced insulin sensitivity based on the increase in fasting glucose, insulin and HOMA-IR score. We observed several previously reported transcriptional changes (We identified the acromegaly gene expression signature in human adipose tissue.

Thus, specific therapeutic targeting of invasive glioma cells is an attractive concept. As cells exit the tumor mass and infiltrate brain parenchyma, they closely interact with a changing micro-environmental landscape that sustains tumor cell invasion.in situ in Invading Glioma Cells (IGCs) compared to tumor core, as well as changes in host cells residing within the infiltrated microenvironment relative to the unaffected cortex. IGCs were found to have reduced expression of genes within the extracellular matrix compartment, and genes involved in cell adhesion, cell polarity and epithelial to mesenchymal transition (EMT) processes. The infiltrated microenvironment showed activation of wound repair and tissue remodeling networks. We confirmed by protein analysis the downregulation of EMT and polarity related genes such as CD44 and PARD3 in IGCs, and EFNB3, a tissue-remodeling agent enriched at the infiltrated microenvironment. OLIG2, a proliferation regulator and glioma progenitor cell marker upregulated in IGCs was found to function in enhancing migration and stemness of GSCs. Overall, our results unveiled a more comprehensive picture of the complex and dynamic cell autonomous and tumor-host interactive pathways of glioma invasion than has been previously demonstrated. This suggests targeting of multiple pathways at the junction of invading tumor and microenvironment as a viable option for glioma therapy.In this study, we used a unique microarray profiling approach on a human glioma stem cell (GSC) xenograft model to explore gene expression changes Glioblastoma (GBM), the most malignant glioma tumor, is highly invasive with a median survival of 16 months despite combined surgical resection, radiotherapy, and chemotherapy. Although the molecular signature of glioma has been investigated in detail The brain consists of numerous cell types forming tissue scaffolds that guide invasion Glioma stem cells (GSCs) are a subpopulation of cells in the tumor capable of self-renewal that can give rise to a heterogeneous tumor in vitro would affect cell physiology and gene expression. Traditional laser capture microdissection studies of glioma invasion focused on glioma specimens from human patients, dissecting neoplastic astrocytes as the invading cells at the rim of the tumor core Ideally, one would perform between\u2013group differential expression analysis for each cellular compartment. However, experimental methods for isolating the IGCs and their microenvironment cellular compartment are neither timely nor cost effective, and isolating them in situ. Subsequently, we found several genes in multiple pathways that may facilitate invasion which were validated at the protein level in xenografted GSCs and in clinical samples from GBM patients. Importantly, OLIG2, a proliferation regulator and glioma progenitor cell marker was upregulated in the IGCs relative to the tumor core. Inhibition of OLIG2 expression reduced migration and stemness and provided functional confirmation as a potential therapeutic target in glioma invasion. Overall, the novel approach in this study allowed us to construct and evaluate a more complete picture of multiple pathways within the area of glioma invasion than has been previously demonstrated.In the present study we used an innovative laser microdissection (LMD) enrichment strategy and gene expression analysis. Differentially expressed genes (DEGs) of IGCs and their microenvironment were simultaneously detected allowing us to deduce functional networks that characterize glioma invasion Following signed informed consent, tumor tissue was obtained from patients (aged \u226518 years) undergoing medically indicated resection of malignant gliomas at the National Institutes of Health as part of a clinical trial approved by the Institutional Review Board (NCI-02C0140). NCI Animal Care and Use Committee (ACUC) approved all animal experiments.Primary glioma stem cells were cultured in NBE medium as previously described GSCs migration was assessed by the xCELLigence RTCA DP device, according to the manufacturer instructions .An intracranial orthotopic model in SCID mice was utilized for the generation of infiltrative glioma xenograft tumors Raw data for this experiment has been deposited in the Gene Expression Omnibus (accession number GSE53717).The probe for each gene was designed and synthesized by NanoString nCounter technologies to match the Affymetrix probe target region . HousekeThe standard immunohistochemistry of paraffin sections and western blotting were performed as previously described in vitro cell migration assay (P\u22640.01). When laminin was used for chemotaxis, only 0923 cells showed significant migration (P\u22640.01). In haptotaxis conditions with fibronectin, only 1228A1 cells demonstrated significant migration (P\u22640.01). None of the GSCs migrated in chemotaxis with fibronectin. Intracranial tumors generated by 0923 and 1228A1 GSCs demonstrated an extensive infiltration into the surrounding cerebral cortex in glioma invasion enrichment analysis. GO terms that were overrepresented and had at least a 30% overlap with at least one other category were identified as significant and 9 genes of cell polarity were downregulated STAT3, which is downregulated, acts as a hub in the EMT network interacting with all other networks. On the other hand, majority of genes (13 out of 18) associated with neurophysiological process and in the cell cycle were upregulated CTNNB1), which plays a central role in the canonical Wnt pathway, acts as a major hub interconnecting with genes and gene products associated with tissue remodeling and wound repair For every dataset, we focused on a subset of genes associated with significant cellular processes and canonical pathways SEMA5A-Plxnb3, AQP4-Dag1, and FGF2-Sdc2) Further analysis identified 17 potential protein-protein binding interactions between the IGCs and the microenvironment residing host cells and PDGFA proteins in the invasive glioma cells was confirmed (Pdgfra was only detected in host cells residing at the AOI (Shh) protein was only observed at the brain cortex and barely detected at the AOI or tumor core transcription factor, is selectively expressed in a subgroup of glioma cells and required for glioma formation in a murine GBM model OLIG2 expression by the IGCs in situ may suggest their stemness, which supports their invasive capability in vivo. We thus investigated whether OLIG2 could serve as a therapeutic target in invading glioma cells. We examined the effect of OLIG2 knockdown (shOLIG2) on the differentiation state, self-renewal, proliferation, cell migration and in vivo invasion of GSCs. As demonstrated in NANOG, OCT4 and SOX2 in 0923 shOLIG2 GSCs were significantly decreased compared to the shControl cells. Immunofluorescence labeling as previously demonstrated GFAP and TUJ1 in 0923 shOLIG2 cells in a more pronounced manner than in shControl cells and SOX9. Our analysis revealed . These probes were designed to only capture human or mouse genes, and a significant (70\u201380%) proportion was indeed validated, and is in line with previous reports using pure samples Previous studies of global gene expression in GBM invasion used LCM of patient specimens did not distinguish changes in the microenvironment at the site of invasion CDK1, BUB1, FBX05, ADAM23 and PLXNA4, associated with cell cycle, cell adhesion or neurophysiological processes were found in both datasets. Though upregulated genes within the cell cycle functional category can imply activation of cellular proliferation, we observed the presence of inhibitory proteins of APC such as BUB1 and FBX05, which could promote cell cycle arrest PLXNA4, a semaphorin receptor required for guidance of newly differentiated neurons, was also common to both datasets Many of the DEGs common for both xenografted GSCs were at a low fold-change, but were nonetheless statistically significant. We then looked at the intersection of our DEGs with those previously reported in the invasive rim of 4 human GBMs in an attempt to correlate our xenograft data to a closely related one derived in a clinical setting EPHA2 and EPHA3 in maintaining the undifferentiated state of GSC has been reported EFNB3 enrichment at the AOI accompanied by EPHA4 expression in the IGCs. Cell contact-mediated bidirectional EFNB3/EPHA4 signaling and migration of interneurons during cerebral cortex development has been previously reported, suggesting the possible usage of this interaction during glioma invasion EFNB3 in the cerebral cortex may provide the switch between cell-cell adhesion and cell migration by A-Disintegrin-And-Metalloproteases (ADAM)-mediated shedding ADAM10, ADAM15 and ADAM19 at the AOI.Being exploratory and hypothesis generating, our analysis suggests some potential protein-protein interactions that have never been explored between glioma cells and host cells at the AOI. Recently the role of OLIG2 positive tumor cells within the AOI strongly suggests that the invasive niche contains GSCs OLIG2 in 0923 GSCs decreased the expression levels of their NSC markers , and reduced their self-renewal and proliferation abilities. Exposure of these cells to differentiation conditions reveals the potential of the shOLIG2 GSCs to differentiate more profoundly into distinct populations of glial and neuronal lineages than GSCs which express OLIG2. Moreover, OLIG2 knockdown inhibited their migration potential in vitro and in vivo. Recently, Siebzehnrubl et al. SOX2 and OLIG2 are induced by ZEB1-miR-200 feedback loop in GBM. Our data support their model, as non-invasive cells in the tumor mass express relatively low levels of OLIG2. Our in vitro data further show that OLIG2 can modulate TWIST and SNAI2 protein expression, the central regulators of EMT cancer invasion OLIG2, TWIST and SNAI2 expression within the AOI of xenografted 0923 GSCs.The presence of CHI3L1 (YKL40), CD44, and STAT3in situ contains both invasive and post-invasive (colonizing) glioma cell populations. We postulate that as cells exit the tumor mass and infiltrate brain parenchyma, OLIG2 expression is enhanced, and as they colonize brain parenchyma, expression of EMT markers is diminished.In epithelial cancer, EMT is evoked during tumor cell invasion and metastasis, leading to the generation of cancer cells with stem cell-like characteristics. Metastases are accompanied by a re-differentiation and a MET type transition, both of which are proposed to be a driving force of metastasis, suggesting that MET allows for growth and colonization of the invasive cell in situ. This study revealed several distinct glioma pathways as well as many previously characterized developmental and neurophysiological processes that had never been described in glioma. These multiple pathways serve as a rich reservoir for therapeutic targets that warrant further investigation. Firstly, our data shows that direct targeting of proteins such as CD44CHI3L1PARD3 may be ineffective at this stage of disease as they are already downregulated in glioma cells at the AOI. On the other hand, the identification of molecules selectively expressed by invasive glioma cells such as OLIG2 may allow the development of therapeutic strategies that specifically target this population of cells EFNB3 may be equally amenable to therapeutic targeting.While our approach of filtering out cross-hybridizing genes may have resulted in the loss of some differentially expressed genes, the exploratory nature of this study enabled us to capture for the first time multiple pathways that take place at the junction of tumor invasion and microenvironment Specific therapeutic targeting of glioma invasion is a field in its infancy.

The implementation of EQA through organising regular EQA rounds and identification of training needs is one of the key activities of the European TB reference laboratory network (ERLTB-Net). The aim of this study was to analyse the results of the EQA rounds in a systematic manner and to identify potential benefits as well as common problems encountered by the participants.The ERLTB-Net developed seven EQA modules to test laboratories\u2019 proficiency for TB detection and drug susceptibility testing using both conventional and rapid molecular tools. All National TB Reference laboratories in the European Union and European Economic Area (EU/EEA) Member States were invited to participate in the EQA scheme.A total of 32 National TB Reference laboratories participated in six EQA rounds conducted in 2010\u20132014. The participation rate ranged from 52.9% - 94.1% over different modules and rounds. Overall, laboratories demonstrated very good proficiency proving their ability to diagnose TB and drug-resistant TB with high accuracy in a timely manner. A small number of laboratories encountered problems with identification of specific Non-tuberculous Mycobacteria (NTMs) (N = 5) and drug susceptibility testing to Pyrazinamide, Amikacin, Capreomycin, and Ethambutol (N = 4).The European TB Reference laboratories showed a steady and high level of performance in the six EQA rounds. A network such as ERLTB-Net can be instrumental in developing and implementing EQA and in establishing collaboration between laboratories to improve the diagnosis of TB in the EU/EEA. Tuberculosis (TB) remains an important public health problem globally and within the European Union (EU) despite significant progress made in the past decade. In 2013, 64 844 TB cases were reported in 28 EU and two European Economic Area (EEA) countries, 6% less than in 2012 and reflecting a decrease in 19 countries [Timely and accurate diagnosis of active TB is a prerequisite for any successful TB control programme and an essential part of the action framework to eliminate TB in low-incidence countries . The labTo ensure compliance with existing international standards of laboratory diagnostics , all labThe introduction of new drug susceptibility testing methods, including rapid culture and molecular tools, and genotyping methodologies necessitated the development of novel as well as modification of existing EQA schemes (eg for rapid molecular tools). A series of recent reports revealed specific problems related to a lack of standardisation in second-line drug (SLD) susceptibility testing and multilocus MIRU-VNTR genotyping \u201315. The A situation analysis of national TB reference functions across the EU formed tThe aim of this study was to systematically analyse the implementation of the EQA scheme across the network from 2010 to 2014, assess performance of the laboratories, identify common problems and discuss the potential benefits of the scheme for the participants.A total of six EQA rounds were conducted from 2010 to 2014 . All 34 The ERLTB-Net developed seven modules covering various types of laboratory techniques: (1) microscopy; (2) primary isolation; (3) identification; (4) drug susceptibility testing; (5) nucleic acid amplification testing (NAAT) for rapid detection of Mycobacteria; (6) molecular drug susceptibility testing using cultures; and (7) molecular drug susceptibility testing using crude DNA extracts .Mycobacterium species and drug susceptibility profiles) were used. Specimen panels included strains with varying DST profiles (M. tuberculosis suspensions treated with chloroform [M. tuberculosis complex (MTBC) strains as well as non-tuberculous mycobacteria (NTM) in various combinations.Artificial sputa (spiked with mycobacteria) were used for preparation of slides (for microscopy) and specimens for primary isolation and rapid NAAT-based detection; all specimens in the latter panels contained equal concentrations of Mycobacteria. For identification and DST, strains with validated characteristics and methods used for species identification (Module 3).Reports received from participating laboratories were analysed against reference results as determined by the EQA provider (NRL Germany and INSTAND e.V), and the percentage of correct results in each module was calculated by dividing the number of correct results by the total number of tests in the module. This provided the score for the given laboratory in the given module. If not all tests within a given module were performed , the overall score was adjusted accordingly. Laboratories scoring \u226580% were issued performance certificates for individual modules. Their individual performances were referred to as \u201cgood\u201d (scores 80.0\u202699.9%) and \u201cexcellent\u2019(100.0%) and overall performance of laboratories achieving 80% score was collectively termed \u201cgood\u201d. Scores under 80% were considered to indicate poor performance for the specific module(s) and no EQA certificate was issued .Error rates for specific methods were calculated as a proportion of incorrect results relative to a total number of individual tests performed by all laboratories across all rounds; for example in Modules 5 and 6 data was analysed by individual drugs. Proportions were compared using the chi-square test using GraphPad Prizm . A p-value < 0.05 was considered as significant.Mycobacterium species identification module in round 1 comprising 94.1% of laboratories within the network (The number of participating laboratories varied across EQA rounds and modules with the largest number of laboratories (N = 32) participating in the network . These 3Performance characteristics of participating laboratories in the EQA rounds 1\u20136 are summarised in The proportion of laboratories using Ziehl-Neelsen (ZN) staining for smear microscopy (Module 1) varied from 46.0% to 58.0% with the remaining laboratories using primarily auramine fluorescent staining; a small number of laboratories (varying from 1 to 4 in different rounds) used the Kinyoun method.There were minor variations in the numbers of laboratories participating in the proficiency testing for microscopy in different rounds with the largest number (N = 27) taking part in round 5 and the smallest (N = 23) in rounds 2 and 4. In rounds 2\u20136, laboratories demonstrated good and excellent performance with only a small number of laboratories failing to achieve the 80% threshold. The proportion of laboratories that were awarded certificates was 80.8% in round 1 and 96.2% in round 6. There were no significant differences in error rates and overall performance characteristics between laboratories using different smear staining methods .M. tuberculosis complex from NTM and identify Mycobacteria species using a range of phenotypic and/or molecular tools. The number of participating laboratories varied from 23 (round 3) to 29 (round 1). Overall scores were good and excellent with only one laboratory in rounds 4 and 6 failing to achieve the 80% threshold. The proportion of laboratories reporting results of species identification varied from 64.3% to 95.7% in different years and largely depended on the composition of the EQA panels (MTBC or NTM) as not all laboratories identify the same spectrum of NTM species routinely on primary specimens. Common problems encountered by the laboratories included reporting the presence of mycobacteria in negative specimens , and inability to detect NTM in positive specimens (N = 2).Within module 2, laboratories were requested to detect the presence of mycobacteria in artificial spiked sputum specimens using bacteriological culture, and (if routinely performed) differentiate In module 3, participants performed species identification of mycobacterial cultures using phenotypic or molecular tools or a combination of both based on standard protocols adopted in those laboratories. The number of participating laboratories ranged from 21 (Rounds 2 and 5) to 32 (Round 1).M. tuberculosis complex with M. bovis caprae and M. bovis BCG being the most problematic species.Within this module, performance varied considerably with a total of three laboratories across all rounds achieving low scores of 20\u201340% and one laboratory misidentifying all specimens in round 5. The majority of participating laboratories, however, demonstrated either good or excellent performance. The proportion of laboratories that were awarded certificates varied from 85.2% (round 4) to 100% (round 6). Common problems experienced by the laboratories included misidentification of NTM and misidentification of species within the M. tuberculosis cultures for sensitivity to five first-line drugs (FLD) and additionally to fluoroquinolones (FQ), capreomycin (CAP), amikacin (AMK), and kanamycin (KAN) (Modules 3\u20135) or FQ, CAP, and AMK (Modules 2 and 6) using any validated phenotypic method routinely used in the laboratory. All but one laboratory used automated liquid culture-based systems for DST for second line drugs; for FLD including PZA methods varied and included Bactec MGIT960 as well as the proportion method on solid media and resistance ratio method on semi-solid and liquid media for PZA.In module 4, laboratories were requested to test five (modules 1\u20132 and 5\u20136) or ten (modules 3 and 4) The number of laboratories taking part in module 4 varied from 22 (Rounds 5 and 6) to 31 (Round 1) and overall performance was good with only two laboratories failing to achieve 80% in one round (round 2). Only susceptibility to rifampicin (RIF) and isoniazid (INH) was tested by all participating laboratories; other drugs were tested by a smaller number of laboratories in accordance with their routine practices. Importantly, the proportion of laboratories routinely testing for susceptibility to pyrazinamide (PZA), FQ and AMK increased over the five years from 65.0%, 56.6%, and 52.2% to 100.0%, 77.3%, and 77.3%, respectively, confirming the ability of many laboratories to detect extensively drug-resistant (XDR) strains.Error rates varied substantially between drugs . PZA wasThis module was designed to test proficiency of laboratories in rapidly detecting MTB complex bacteria in sputum specimens using nucleic acid amplification tests (NAAT). The number of participating laboratories ranged from 19 (Round 4) to 22 (remaining rounds) and performance was good with all but two laboratories (in Rounds 5 and 6) achieving scores >80%. The proportion of laboratories using GeneXpert methodology for TB detection in primary specimens increased from 35.0% in 2011 to 65.2% in 2014. Other methods used for TB detection in primary specimens included BD ProbeTec DTB used by up to 13.6% of laboratories in different years, and Cobas TaqMan GT Mycobacteria Direct , and Artus PCR kit .There were no differences in error rates and overall performance characteristics between GeneXpert and other NAAT methods for rapid MTB complex bacteria identification.In Module 6, proficiency of laboratories in rapidly detecting resistance to selected first and second-line drugs on cultures was tested. The number of participants remained relatively stable over five years and ranged from 18 (Round 1) to 22 (Round 2). Nearly all laboratories used line probe assays (LPAs) for molecular DST. A small number of laboratories (<10%) used in-house validated assays including targeted gene sequencing and pyrosequencing,Performance was good with only one laboratory in round 6 failing to achieve the 80% threshold score. The proportion of laboratories adopting technologies for rapid DST for second-line drugs increased from 66.7% (round 2) to 85.0% (round 6). Overall concordance with reference results was high, exceeding 99% for all drugs . Unlike M. tuberculosis strains, and therefore inactivated non-hazardous crude DNA extracts isolated from fully sensitive, poly- and multidrug-resistant strains were used. Module 7 panels were only included in rounds 3 and 4 and results were obtained from 26 and 24 laboratories, respectively.The primary aim of this module was to test the proficiency of the laboratories in rapid detection of highly drug-resistant Overall performance was good with a total of 8 errors reported . All laboratories achieved scores >80%. Errors were not confined to any specific drug and were lower for RIF (0.3%) and higher for INH (1.0%) . ConcordThe primary aim of this study was to systematically analyse the performance of national TB reference laboratories for detection, identification and drug susceptibility testing for TB diagnosis across the EU/EEA through a comprehensive series of EQA rounds, identify common problems and discuss the potential benefits of the EQA scheme developed within the EU-wide TB reference laboratory network.Overall, laboratories demonstrated good proficiency with scores consistently exceeding the 80% threshold in the vast majority of the laboratories. Steady high performance in both phenotypic and rapid molecular methods over five years with only 27 individual module result failures shows an ability of national TB Reference laboratories to diagnose TB and drug resistance TB with high accuracy in a timely manner. The principal results of our study were in agreement with another report demonstrChallenges with microscopy and species identification in rounds 1\u20133 have been addressed through corrective actions including additional training and laboratory visits. No major problems were detected in primary isolation (module 2). An in-depth analysis of laboratory performance for phenotypic DST has allowed us to identify methodological problems with specific anti-TB drugs including PZA, EMB and, interestingly, KAN and AMK. This is largely in agreement with earlier reports demonstrating a lack of standardised methodologies and drug concentrations for PZA (type of media) and KAN ,19,20 anProficiency of laboratories in identification and DST using rapid molecular tools proved to be good and excellent. High scores were achieved by the laboratories in molecular DST on cultures and crude extracts and there was a significant increase in the number of laboratories adopting molecular techniques (particularly the GeneXpert system), which is critical for the timely detection of MDR strains and prevention of transmission ,5.Our study identified several common challenges in EQA schemes with relatively low participation rates being one of them. Significant variability of participation rates (52.9\u201394.1%) across modules and/or EQA rounds can be in part explained by the fact that not all laboratories perform all the tests routinely ; data collected outside the current study suggests that up to 25% of NRLs are not routinely engaged in primary laboratory work (unpublished data). A small number of laboratories encountered challenges in sending the results within the agreed timeframe or were unable to take part due to financial constraints . This highlights the importance of adequate management and careful financial planning including allocation of funds for participation in EQA schemes. Other problems encountered in individual laboratories preventing them achieving the 80% threshold included clerical errors (mislabelling etc), incorrect interpretation of molecular and phenotypic tests results, as well as cross-contamination issues. These problems may be indicative of more general problems in the laboratory practice and should be taken into account in the laboratory quality management.Laboratory services play a crucial role in improving the delivery of health care and reducing the prevalence of TB and drug-resistant TB in particular. Quality assessment through proficiency testing is a fundamental tool used to ensure accuracy of test results by comparing quality between laboratories, evaluating performance and detecting errors so that corrective actions, including additional training and support visits, can be taken in a timely manner to restore the high quality of services.M.tuberculosis genotyping [Overall, results of our study and earlier reports on proficiency testing and EQA schemes for notyping ,14 demonParticipating laboratories benefited from the developed EQA program in a number of ways including free of charge EQA and performance certificates essential for their accreditation by relevant national bodies, availability of training for their staff members as well as targeted actions including direct consultations with the EQA providers and support visits from scientists within the network who were able to provide additional expertise and help to NRLs where needed. Steadily high performance during the implementation period suggests that aforementioned network activities addressing the challenges identified through the analysis of EQA results were effective. Sustainability of EQA and training activities at EU/EEA level as well as their further development through inclusion of novel validated methodologies (eg Next Generation Sequencing) are crucial for ensuring timely and high-quality laboratory diagnosis of TB in the EU/EEA.S1 Table(DOCX)Click here for additional data file.S2 Table(DOCX)Click here for additional data file."} +{"text": "Cerebral near-infrared spectroscopy (NIRS) represents an exciting prospect for the non-invasive monitoring of cerebral tissue oxygenation in traumatic brain injury (TBI).

Heritability is estimated as high as 90% for ASD with a recently reported compilation of 629 clinically relevant candidate and known genes. We chose to undertake a descriptive next generation whole exome sequencing case study of 30 well-characterized Caucasian females with autism from multiplex families. Genomic DNA was used for whole exome sequencing via paired-end next generation sequencing approach and X chromosome inactivation status. The list of putative disease causing genes was developed from primary selection criteria using machine learning-derived classification score and other predictive parameters . We narrowed the variant list to 10 to 20 genes and screened for biological significance including neural development, function and known neurological disorders. Seventy-eight genes identified met selection criteria ranging from 1 to 9 filtered variants per female. Five females presented with functional variants of X-linked genes ( PTEN tumor suppressor gene ; d1 = peak height of digested DNA from the first allele and u1 = peak height of undigested DNA from the first allele; d2 = peak height of digested DNA from the second allele and u2 = peak height of undigested DNA from the second allele. Highly skewed XCI is defined as >80% calculated ratio for either one of the AR gene alleles in the digested DNA sample. To ensure the reproducibility of XCI results and equal amplification of both alleles, the digestion, PCR amplification, and genotyping were repeated up to three times in several samples.The digestion process preferentially degrades activated (unmethylated) over inactivated (methylated) DNA. Undigested DNA is preferentially amplified and produces larger peak heights. The peak height values for digested DNA is normalized using peak height values for the undigested DNA for each subject. The percentage of XCI for each XCI status for each subject was assigned to one of the three mutually exclusive categories: (i) randomly selected inactivation of either allele from each X chromosome (XCI = 50%:50% to 64%:36%); (ii) moderately skewed inactivation favoring 1 allele of one of the X chromosomes (XCI = 65%:35% to 80%:20%); and (iii) highly skewed inactivation of a single allele representing one X chromosome (XCI > 80%:20%). The relative frequency of random, moderate, and highly skewed XCI categories was determined for the females with autism. The binomial frequency distribution of X-linked gene variants (present or absent) among females with autism spectrum disorder exhibiting moderate and high levels of XCI skewness were approximated using Yates\u2019 chi-squire test and odds ratios were calculated with 95% confidence intervals.The top genes chosen were based on the final selection criteria identified for each female and evaluated for biologic function and whether each gene was previously reported as a clinically relevant candidate or known gene for autism .

About 60% of the diagnostic mutations were not previously reported [In summary, we shared our experience using a descriptive next generation whole exome sequencing case study approach examining 30 well-characterized Caucasian females with autism between 5 and 16 years of age recruited from multiplex families enrolled at the AGRE for research purposes. Interpretation of DNA findings are limited due to an inability to study other affected and non-affected family members to determine whether the gene variants were de-novo or inherited in origin for correlation with clinical phenotypes and lack of Sanger sequencing confirmation.

However, an influence of right ventricular dysfunction on cardiovascular events is becoming apparent. The incremental prognostic value of right ventricular ejection fraction (RVEF) on future arrhythmic events among those being considered for device therapy has not been well examined. In this study we evaluate the significance of MRI-based measurement of RVEF versus other clinical and MRI-based variables for their ability to predict Sudden Cardiac Death (SCD) or Appropriate ICD therapy.Consecutive patients with cardiomyopathy were evaluated for device candidacy. All patients underwent a standard Late Gadolinium Enhancement (LGE) MRI protocol followed by a blinded core-laboratory based quantification of left ventricle (LV) and right ventricle (RV) volumes, ejection fraction (EF) and total hyperenhancement (HE).

Although the fauna was dominated by polychaetes and peracarid crustaceans, patterns in community structure could only weakly be explained by the measured environment (~35%). This is attributed to the generalist nature of the species recovered, which were widely distributed amongst different sediments, water-depths and latitudes.

Furthermore, the PHBs increase the cellular pools of acetyl CoA via mechanisms that may include ATP-citrate lyase. Coordinately, there are increases in acetylation of histone 3 and expression of the tumor suppressor proteins p21 and p27, a mechanism that most likely involves the down regulation of class I and II histone deacetylases and up regulation of histone acetyl transferase via ERK1/2 signaling.

Carbon monoxide (CO) affects several metabolic pathways and de novo protein synthesis is crucial in the cellular responses to the gasotransmitter. Herein a selection of commonly used reference genes was analyzed to identify the most suitable internal control genes to evaluate the effect of the CO on gene expression in cultured cortical astrocytes. The cells were exposed to CO by incubation with CORM-A1 (CO releasing molecule A1) and four different algorithms were applied to better evaluate the stability of eight putative reference genes. Our results indicate that Gapdh and Ppia (peptidylpropyl isomerase A) is the most suitable gene pair for normalization of qRT-PCR results under the experimental conditions used.

A partial fragment of the cytochrome oxidase I gene was sequenced in 366 individuals collected from localities at both sides of each discontinuity during three time periods. Although localities showed genetic fluctuations through time, a significant gradient was detected along the coast for all sampling periods. Significant inter-annual differences identified within the Alicante area, north of the Almeria-Oran Front, were associated with shifts in the relative contribution of Atlantic and Mediterranean water masses. The persistence of a clinal pattern in the Atlantic-Mediterranean transition area together with local fluctuations suggests a complex balance of dispersal and selection.Spatial genetic studies often require sampling broadly separated areas, difficult to access simultaneously. Although comparing localities surveyed at different time periods might result in spurious genetic differentiation, there is a general believe on the stability of genetic structure through time, particularly if sampled localities are isolated or very distant.

Basic histological quantification of T lymphocyte density, cytotoxicity, and memory by CD3, CD8, and CD45RO, respectively, has demonstrated that increased infiltration of T lymphocytes is associated with statistically significant improvement in patients' disease-free survival (DFS) and overall survival (OS) in colorectal carcinoma (CRC). Delineating the location of T lymphocytes into two areas within the primary tumor, the center and the invading margin is termed Immunoscore.In this study we examined whether tumor genotype could predict the clinical outcome of patients with CRC and if combining Immunoscore with analysis of the tumor genotype could further enhance the accuracy of predicting clinical outcome. We analyzed 200 primary colorectal tumor samples for mutations in 50 common driver genes, including those implicated in models of colon carcinogenesis . Each mutation was then assessed for prediction of DFS. Patients presented with a mean of 4 \u00b1 2 mutations. The most common mutations were in KRAS (58%), TP53 (49%) and APC (37%). Neither, a single mutation or the number of mutations significantly predicted clinical outcome.We examined whether mutations in the primary tumor were associated with presence of metastasis. Mutational profiles were remarkably similar between primary tumors from patients whether or not they had metastatic progression at the time of surgery. None of the 50 major cancer genes was more frequently mutated in patients with metastasis. However, using integrative analysis we found that tumors from patients with metastatic disease downregulated adaptive immune genes including those involved in co-stimulation, proliferation and positive regulation of T cells. Furthermore when analyzing the ability to predict patients' OS using Immunoscore in these late stage tumors, high Immunoscore still distinguished patients with better clinical prognosis. These data suggest immune contexture accurately predicts clinical outcome regardless of tumor stage. Further analysis of pre-existing immunity together with the analysis of tumor genotype may provide better understanding of tumor progression and invasion."} +{"text": "Nigeria is expected to be the nation with the 11th highest population of older persons by 2015.

From the group of 42 patients were simultaneously performed ELISA and WB in 26 persons. In this group we found positive LymeSpot in 4 patients and cutoff value in 2 patients. In the group of 4 patients with positive LymeSpot was detected higher level of IgM antibodies in 3 patients and only IgG antibodies in 1 patient. They were patients with clinical manifestations of LB who were treated with antibiotics afterwards. Among 20 patients with negative results of LymeSpot these findings correlated with antibody response in 8 patients (40%). In this group we detected seronegative finding (IgM-IgG-) or finding of passing through LB (IgM-IgG+). In other 12 patients with negative LymeSpot test we detected serological finding of beginning (IgM+IgG-) or running LB (IgM+IgG+). They were mostly patients without clear symptoms of LB, patients with long-term positivity of IgM antibodies without clinical manifestations of LB or patients after antibiotic therapy.Our first experience shows that results of LymeSpot test better correlate with clinical findings and LB activity as well as can be effective marker of success of antibiotic therapy."} +{"text": "The majority of distal radius fractures are associated with an ulnar styloid fracture -3.

By characterizing the methylation status of three different imprinted loci , monitoring the expression of two parentally imprinted genes (SNRPN and H19) and carrying out genome-wide SNP analysis, we provide evidence that this cell line was established from the activation of a mutant oocyte by diploidization of the entire genome. Therefore, our SMA parthenogenetic HESC (pHESC) line provides a proof-of-principle for the establishment of diseased HESC lines without the need for gene manipulation. As mutant oocytes are easily obtained and readily available during preimplantation genetic diagnosis (PGD) cycles, this approach should provide a powerful tool for disease modelling and is especially advantageous since it can be used to induce large or complex mutations in HESCs, including gross DNA alterations and chromosomal rearrangements, which are otherwise hard to achieve. Parthenogenesis is the process by which an oocyte is stimulated to divide and develop into an embryo without being fertilized. It can be artificially induced by triggering unfertilized eggs to resume meiosis without undergoing cell division, or achieved spontaneously following failed fertilization. The resulting embryos, which contain only maternal chromosomes, are unviable due to poor development of extra embryonic tissues \u20137. Yet, This study was approved by the Ethics Committee at Shaare Zedek Medical Center (IRB 87/07) for the derivation of HESC lines from genetically affected PGD derived embryos, in compliance with protocols approved by the National Ethics committee.The SMA HESC line was established from a PGD derived embryo that developed into a fully grown hatched blastocyst by day 7 following fertilization. At this stage the inner cell mass (ICM) was mechanically isolated by manual cutting with an ultra-sharp splitting blade (Bioniche). The intact ICM clump was placed on a feeder cell layer of mitomycin C-inactivated mouse embryonic fibroblasts and cultured in HESC media . Outgrowths of proliferating cells were manually propagated using the cut-and-paste method.

The extent of the mechanical and thermal effects strongly depends on the ultrasound parameters and also potentially the acoustic properties of the tumor. High temperatures lead to coagulative necrosis with little immunogenic response as tumor antigens most likely denature during the ablation. As antigen presentation by activated dendritic cells (DCs) is necessary to activate T cells during an anti-tumor immune response, we hypothesize that non-ablative FUS treatment can be used to increase tumor immunogenicity by activating molecules that enhance intratumor dendritic cell (DC) infiltration and T cell activation. One of the first steps in this process is an activated stress response, including surface calreticulin (CRT), high mobility group protein B1 (HMGB1) release, ATP secretion and heat shock protein 70 (HSP70) surface expression and release. Using non-ablative FUS, antigen release can be stimulated by mechanical stress, thermal stress, or both. Here, we examine the stress response following non-ablative FUS treatment in three murine tumor models with varying consistencies and determine the causative agent of the stress.in vivo in three subcutaneous tumor models in C57BL/6 mice, varying the mechanical and thermal energies to determine which protocol results in the greatest anti-tumor immunity. We investigated CRT surface expression, ATP release and both intra and extracellular expression/release of HMGB1 and HSP70. Since the effect of FUS treatment may vary depending on the cancer cell type, we investigated three different mouse cancer cell lines varying in consistency from solid to fluid .

The data for this study was comprised of crossbred heifers (n = 681) and steers (n = 836) from commercial feedyards. Eleven molecular breeding value (MBV) scores derived from SNP panels of candidate gene polymorphisms and two-leptin gene SNP (UASMS2 and E2FB) were evaluated. The empty body fat (EBF) and the shrunk body weight (SBW) at 28% EBF (AFSBW) were computed by the Cattle Value Discovery System (CVDS) model using hip height (EBFHH and AFSBWHH) or carcass traits (EBFCT and AFSBWCT) of the animals. The DOFHH was calculated when AFSBWHH and ADGHH were used and DOFCT was calculated when AFSBWCT and ADGCT were used. The CVDS estimates dry matter required (DMR) by individuals fed in groups when observed ADG and AFSBW are provided. The AFSBWCT was assumed more accurate than the AFSBWHH because it was computed using carcass traits. The difference between AFSBWCT and AFSBWHH, DOFCT and DOFHH, and DMR and dry matter intake (DMI) were regressed on the MBV scores and leptin gene SNP to explain the variation.

As a result, glycogen storage occurs in muscles and patients present a wide clinical spectrum ranging from early onset severe cardiomyopathy (EOPD) to adult onset forms (LOPD). Severe loss of GAA activity correlates with early onset and severe phenotypes. Residual enzyme activity warrants later onset and a slowly progressive course, although a strict correlation is not always observed. Patients with Classic infantile Pompe disease show hypotonia, macroglossia, respiratory insufficiency and early death for cardiorespiratory failure.The availability of enzyme replacement therapy (ERT) with alglucosidase alfa ( human recombinant GAA) has changed the natural history of the disease allowing most children with EOPD a longer survival and a longer preserved muscle performance with increased quality of life in LOPD.The experience of the Regional referral Center for Metabolic Diseases, University of Catania, concerns 11 patients ( 9 months to 65 years at the time of the diagnosis). Their clinical and laboratory follow-up included eye tracking and Muscle MRI.EOPD, with a severe clinical picture since the first weeks of life and cardiomyopathy was observed in a newborn who died at age 4 months, despite early started and high dosage ERT. Another girl with EOPD is on ERT since the age of 9 months and, today, after 7 years of treatment shows only mild signs of muscle weakness and no cardiac involvement.Five more LOPD patients on ERT had a significant improvement of blood parameters including transaminases, LDH and CPK. No progression of muscle impairment was seen after 5 to 8 years of treatment, except for one 35 years old man, who was already severely compromised and did not show any benefit in terms of respiratory ventilation.In a recently performed Italian survey of classical Pompe disease treated with ERT, a substantial improvement in cardiac parameters and gross motor function was observed, even if residual muscle weakness still exist and gross motor function remain below age-appropriate levels.The different response to ERT depends on several factors mainly on timing of treatment (worse outcome if started later than 5 months of age) and cross reactive immune material (CRIM-negative status associated with less good response to ERT).Although some residual mild weakness is present in treated patients, ERT has demonstrated its effects on respiration, lowering nocturnal apneas and allowing patients a better quality of life."} +{"text": "Road traffic injury (RTI) has assumed major public health importance world-wide and the burden is heavier on the health-care infrastructure of countries in Sub-Saharan Africa. In Nigeria, RTI is the leading cause of trauma related morbidity and mortality. While there are some published epidemiological reports on RTI in the region, studies on the mechanism of causation of road traffic crashes (RTC) are not available.Over a 9-month period, we prospectively captured the 571 victims of RTC presenting to a single tertiary health care center in Nigeria. Data collected include demographic data, Mechanism of causation of RTC, Injuries sustained and outcomes.Over three-quarters of the victims are young people and half were either traders (27.5%) or students (20%). Pedestrians, motorcycle riders and open truck occupants (people sitting at the rear loading compartment of trucks) often had fatal injuries. Analysis of collision patterns showed that lone crashes were the most frequent though car-to-motorcycle crashes caused a quarter of the deaths. Host factors were responsible for four-fifths of the crashes while vehicular and environmental factors accounted for the remaining. On binary regression analysis, head injured victims had higher odds of dying than the non-head injured (Odds ratio = 6.5).This paper elucidates the mechanisms of causation of and types of injuries sustained following RTC in Nigeria and thus provide opportunities for prevention and control of this unacceptable situation. Worldwide, Road Traffic Injury (RTI) has assumed major public health concern as it is responsible for an increasing number of morbidity and mortality. The World Health Organization (WHO) has attributed this increase to rapid urbanization and motorization and has aptly identified RTI as the price humanity must pay for modernization . The cosAll RTI victims who presented to University of Ilorin Teaching Hospital between October 2006 and June 2007 were prospectively captured. Biodata of victims, details of how the RTI occurred (mechanism of causation), the location of the victim during the incident (host status), the types of injuries sustained and eventual outcome was documented. Age categorization: The age of the victims were categorized into three groups for statistical analysis. Host status: The host status was also categorized as riders of motorcycles (two wheeler vehicles); drivers of cars, buses or trucks (four wheeler vehicles); passengers of motorcycles; passengers of four wheeler vehicles; pedestrians and open truck occupants . Crash mThere were 571 patients over the nine month period consisting of 427 males and 144 females (M:F ratio = 3:1). There was no statistical significant difference in outcome between the sexes (p = 0.439). Median age was 30 years (range 6 months to 84 years). Over three-quarters of victims were young people, with another one-fifth being middle-aged and only 0.5% were elderly. There was however no significant statistical difference in outcomes between the age categories (p = 0.168). Majority of victims were either engaged in business or trading (27.5%) or were students (20%). The least involved group was the professional (2%). There were a total of 388 crashes consisting of 310 single patient and 78 mass (>1 victim) involvements (single: mass crash ratio = 4:1). Two crashes which involved 15 and 11 casualties constituted the highest mass crash casualty.Pedestrians, motorcycle riders and open truck occupants represenOf the various collision patterns, lone crashes (Solitary crash involving only one vehicle with no collision with another vehicle or pedestrian) were the most frequent on our roads accounting for about 29% of 388 crashes and were responsible for the highest casualty of 199 patients (35%) .

SoutAbout 43% of victims in this study were passengers of 4 wheeled vehicles, 28.4% were on motorcycles (rider and passengers), and 14.5% were pedestrians. These three groups of road users are particularly prone to RTI in the developing countries . The motEighty percent of crashes were due to host factors and accounted for 74% of morbidity and about 84% of mortality. Over-speeding/inappropriate speed constituted the major host problem (80%). Odero's presentation also identified human error as leading cause with over-speeding topping the list in Kenya, Uganda, South Africa, Ghana, Zimbabwe, Ethiopia and Tanzania . AlcoholThe following recommendations are suggested to policy makers to reduce the occurrence of and injuries from RTI: 1) Enforcement of helmet use by motorcyclists, seat belts by drivers and passengers of 4 wheeled vehicles and a law against travelling on the back of trucks and Lorries. 2) Strict regulation and enforcement of speed limit. The Federal Road Safety Corps should be equipped with speed detectors in their patrol cars and our roads must have speed detectors at strategic points with camera facilities. 3) Appropriate road engineering with road signs and conspicuously displayed speed limits to guide road users. Provision of road shoulders and service lanes will prevent broken down vehicles from being impediments to traffic. 4) Construction of new roads to open new network of roads so as to decongest the major roads. 5) Regular road maintenance to eliminate potholes. 6) House to house waste collection coordinated by the local government authority should be introduced to replace the current practice of refuse tanks dumped on major roads. 7) Use of \u201cTokunbo\u201d tires must be banned urgently.This paper has elucidated the mechanisms involved in causation of RTIs, the injury spectrum seen in involved victims and the relationships of these variables to outcome of clinical management of the victims.

SOCS family proteins consisting of 8 proteins (CIS and SOCS1-7) inhibit JAK/STAT protein activity to maintain proper cytokine functions. Initially identified for the negative feed-back function of cytokine signal transduction, suppressors of cytokine signaling (SOCS) have emerged as multi-functional protein involved in the regulation of development, apoptosis and oncogenesis. Recent reports showed that SOCS can be also affected by cytokine and other cell signaling factors to regulate cancer development and progression as well as cell death. The present study was aimed to investigate various effects of SOCS1 protein on the tumor suppressive function. We have found that SOCS1 promotes radiation-induced apoptosis of colon cancer cells through cell cycle arrest at G1 involving activation of p53 and p21 induction. SOCS1 also exhibits radiosensitization effects on the growth of implanted colon tumor cells in nude mice. As a mechanism of anti-tumor action of SOCS, we now present the data on the suppressive effects of SOCS1 on tumor cell migration and invasion. Notably SOCS1 over-expression and knock-out inversely regulates the expression of EMT markers such as E-cadherin and vimentin along with modest morphological change of cells from epithelial to fibroblast shape, representing EMT process. Data on the invasion and EMT signaling pathways suggest that SOCS1 potentially regulates tumor cell invasion and metastasis in vitro and in vivo in colon cancer models.

Repetitive transcranial magnetic stimulation and transcranial direct current stimulation may correct the disruption of cortical excitability and effectively contribute to the restoration of movement and speech. The present paper analyses the results of non-invasive brain stimulation (NIBS) trials, highlighting different aspects related to the repetitive transcranial magnetic stimulation frequency, transcranial direct current stimulation polarity, the period and stimulation places in acute and subacute ischemic strokes. The risk of adverse events, the association with motor or language recovery specific training, and the cumulative positive effect evaluation are also discussed.Abbreviations: AAT = Aachen Aphasia Test, BDNF = brain-derived neurotrophic factor, IFG = inferior frontal gyrus, M1 = primary motor cortex, MRI = magnetic resonance imaging, NIBS = non-invasive brain stimulation, PET = positron emission tomography, rTMS = repetitive transcranial magnetic stimulation, SLT = speech and language therapy, STG = superior temporal gyrus, tDCS = transcranial direct current stimulation, NIHSS = National Institutes of Health Stroke Scale After an injury, there are changes in motor and sensitive cortical somatotopies, both in the damaged region and the remote areas from ipsi- and contralateral hemisphere. An increased activation in contralesional primary motor cortex (M1), bilateral ventral premotor cortex and supplementary motor area are commonly found in stroke patients [3]. While the healthy subjects show greater activity in the contralateral hemisphere to the moving hand, stroke patients assume a bilateral pattern in general [4]. Due to its intrinsic plasticity, the brain has the capacity to restructure its neural networks and to reconfigure its activity after an ischemic or haemorrhagic stroke. The metabolic and functional cerebral alteration can be observed by functional imaging studies (positron emission tomography (PET) scan and functional magnetic resonance imaging (fMRI), and also by transcranial magnetic stimulation mapping of the motor area [5]. These mechanisms are activated differently depending on stroke size and location. Small ischemic or haemorrhagic lesions may be compensated by the recruitment of residual language areas and the increase in perilesional activity. By contrast, the larger lesions in the language regions are followed by the recruitment of homotopic non-dominant areas [6]. In the recovery of aphasia, three models of neuroplasticity were framed by prior research: (1) activation of perilesional language areas in the dominant hemisphere, (2) recruitment of homologue area in the non-dominant hemisphere, and (3) improper recruitment of different regions in the non-dominant hemisphere [5]. Secondary to the decrease of transcallosal inhibition, some right hemispheric areas may deploy an inhibitory effect over the residual perilesional areas in the left hemisphere, interfering with the language recovery. Based on these data, a new model for the recovery of aphasia was proposed based on the suppression of non-dominant hemisphere activity and the stimulation of the perilesional areas in dominant hemisphere [5]. However, the role of right language homologues in the early recovery after stroke seems to be transient, to an extent perilesional neuronal recruitment occurs [4]. Transcranial direct current stimulation (tDCS) of the brain is an electrophysiological method which may be used to modulate the neocortical excitability. A direct current generator is connected to two patch electrodes (an active and a reference one) positioned over the scalp, to stimulate the subjacent tissue with low amplitudes currents (0.5 - 2.0 mA) and to modify the threshold for discharge of cortical neurons. The modulation of cortical excitability is polarity-dependent: \u201canodal stimulation\u201d (increased in network excitability) \u2013 when the active electrode generates a positive potential compared to the reference electrode; \u201ccathodal stimulation\u201d (decreased in network excitability) \u2013 when the active electrode generates a negative potential . Repetitive transcranial magnetic stimulation (rTMS) is another therapeutic tool that can contribute to the modulation and reconfiguration of different cortical areas. In contrast to tDCS, rTMS results in the induction of action potentials and depolarization of the neuronal membrane. The principle of transcranial magnetic stimulation is to produce a perpendicular magnetic field, by a stimulating coil, which induces an electric field, which, in contact with the cerebral tissue, is transmitted as an electric current, parallel to the generating coil. The depth of the stimulation depends on the type of coil and the intensity of the stimulation. The excitatory or inhibitory effect is correlated with the frequency of rTMS: high frequencies (\u2265 5 Hz) are excitatory, while low frequencies (\u2264 1 Hz) are inhibitory . By modulating cortical excitability with respect to neural plasticity, these two non-invasive brain stimulation (NIBS) techniques represent potential therapeutic tools in recovery after stroke [10-14]. This model suggests that the balance between the left and the right hemisphere of stroke patients is altered by an increased interhemispheric inhibition from the unaffected hemisphere to the affected hemisphere. Accordingly, a therapeutic effect may be obtained either by increasing the excitability of the affected hemisphere, or by decreasing the excitability of the unaffected hemisphere [10]. The mechanism of excitability enhancement in the motor cortex underlies the motor learning and the use-dependent plasticity, which are impaired in the affected hemisphere. Other positive effects of the NIBS are the enhancement of neural coupling between the primary and secondary motor areas in the affected hemisphere, the reduction of the hyperactivity in the primary and secondary motor areas in the unaffected hemisphere, and the excitability modulation in both hemispheres [10].There are two main directions of NIBS treatment in neurorehabilitation: the motor deficit and the speech disorders. The improvement of motor and language performances is based on interhemispheric competition theory [15]. The major disadvantage is the deterioration of bimanual movement due to the reduction of transcallosal inhibition that controls that kind of movement. This possible consequence may be prevented by applying a low frequency rTMS concomitant with anodal tDCS over the affected hemisphere [16]. The neural modulation induced by NIBS and the improvement of motor and speech deficits can be sustained by subsequent motor training and speech therapies .The advantages of inhibitory NIBS over the intact hemisphere are the uniform response and the lower risk of potential epileptic seizures, which are more probably to appear after rTMS in the infarcted area . The genetic polymorphism can be involved and may explain the different response of stroke patients to this therapy. BDNF is one of the factors strongly involved in synaptic plasticity of the human motor cortex [9]. The consequence of BDNF val66met, a common single nucleotide polymorphism, is the reduced secretion of BDNF [19]. This is clinically expressed by a poorer retention in short-term motor learning and slower cognitive and motor recovery . Therewith, the individual variation in response to rTMS may be explained by the difference in BDNF concentration [20]. Although it was demonstrated that the early rehabilitation facilitates motor recovery after stroke, the application of NIBS in acute stages is controversial [21]. In this respect, a recent Cochrane meta-analysis evaluated the efficacy and safety of rTMS in recovery after stroke regardless of the duration of illness [22]. Nineteen randomized controlled trials (RCTs) with a total of 588 patients were included. Even if the rTMS treatment was not associated with a significant improvement in activities of daily living, or a significant improvement of motor function, a positive trend was noted, larger and homogeneous RCTs being needed in order to confirm the results [22]. The majority of the clinical studies evaluating the role of rTMS in rehabilitation were performed in subacute and chronic stroke patients, few data being available for acute stroke [22]. Also, epileptiform discharge on EEG and seizures, can be noted especially after high-frequency rTMS (10 Hz) [11].The most encountered adverse events reported in clinical trials evaluating rTMS are transient or mild headache (2.4%), anxiety (0.3%), neurocardiogenic syncope after initial exposure to rTMS (0.6%), exacerbation of pre-existing insomnia (0.3%) and local discomfort at the site of the stimulation [23]. In 2005, Khedr and colab. applied 3 Hz, in 10 daily stimulation sessions on the affected side in 26 patients with acute cortical stroke and in 26 patients with acute subcortical stroke (recruited between the fifth and tenth day post-stroke). The evaluation of motor recovery showed an improved function in the paretic hand in both groups [24]. Liepert and colab. showed that one session of 1 Hz rTMS therapy on the contralesional hemisphere in 12 patients with acute subcortical stroke (mean 7 days), disclosed an enhancement in the hand functioning at Nine Hole Peg Test (a transient improved dexterity of the affected hand), but no change in the grip strength [25]. In 2010 Khedr and colab. published another study on 48 acute stroke patients which supported 3 Hz, 130% resting motor threshold intensity, or 10 Hz, 100% resting motor threshold intensity, in 5 daily stimulation sessions on the ipsilateral hemisphere. The improved hand function persisted for 12 months after rTMS treatment [26]. Participants were divided in two groups \u2013 the study group (5 patients) \u2013 stimulated in the right pars triangularis, and the control group (5 patients) \u2013 stimulated in vertex (sham stimulation). The results pointed out an improvement of Aachen Aphasia Test (AAT) scores in patients from the study group, but not in those with sham stimulation. Compared with baseline, a larger activation index was observed on PET scan in the right hemisphere in the control group compared with the study group, 2 weeks after rTMS, suggesting that inhibitory magnetic stimulation of the right-hemispheric Broca homologue followed by SLT might be a feasible and effective complementary therapy for post stroke aphasia [26]. Weiduschat studied the effect of 1 Hz rTMS stimulation together with subsequent speech and language therapy (SLT) in 10 right-handed patients at 16 weeks after stroke [27]. The patients were included between 2-12 weeks after the onset. This group was compared with a sham stimulation group . The assessment included Computerized Picture Naming Test, Boston Diagnostic Aphasia Examination and Aphasia Severity Rating Scale. After a follow-up period of 15 weeks, no differences in naming accuracy between the two groups were noted, but reaction time was slightly faster in real rTMS group [27].Waldowski and collab. studied the effects of 1 Hz rTMS over pars triangularis and pars opercularis from the right inferior frontal gyrus (IFG), followed by 45 min/ day SLT, in 13 right-handed patients with aphasia [18]. Forty patients received 3 weeks of motor training on the paretic upper limb (45 minutes daily) preceded by 30 minutes of 1 Hz rTMS (stimulated group) or by 30 minutes of sham rTMS over the contralesional M1 (control group). The functional assessment of the paretic hand (by Wolf Motor Function Test and NIHSS) performed before, immediately after and at the 3 months follow-up revealed no statistically significant differences between the two groups [18]. In a randomized, sham-controlled, double-blind study, Seni\u00f3w and colab. evaluated the association of low-frequency rTMS of the contralesional M1 area with physiotherapy [13]. In 2013, Heiss et al. analyzed for the first time the consequences of the inhibitory NIBS over the contralesional IFG in left-handed aphasic patients. They reported the results of a randomized controlled trial comparing the effect of combined rTMS/ SLT in 29 right-handed patients with left hemisphere infarcts and 2 left-handed patients with right hemisphere infarcts. The start of treatment was between 25 and 93 days after stroke onset. Fifteen right-handed patients received 10 sessions of inhibitory 1 Hz rTMS over the triangular part of the right IFG (20 min each) followed by 10 sessions of SLT, while 14 right-handers with heterogeneous aphasia forms received 10 sessions of 20 min rTMS over the midline at the vertex (sham stimulation). Two left-handers were treated according to the same protocol with real rTMS over the left hemisphere. The speech performance was evaluated by AAT, and the language activation patterns were assessed with PET scan prior to and after the treatment. The results showed better recovery of language function in right-handed patients after real rTMS than in sham-treated right-handers. Furthermore, a shift of network activity towards the left, ipsilesional hemisphere was observed in treated right-handers, while the sham group maintained the activation in the contralesional hemisphere. Both left-handed volunteers also improved, the PET scan showing a very small interhemispheric shift (less than in rTMS-treated right-handers) and a consolidation of active networks in both hemispheres [12]. In both groups, the inhibitory NIBS was followed by SLT 45 min/ day. The global AAT and naming subtests disclosed better scores, which correlated with a PET activation in the left hemisphere in rTMS group post-treatment compared to the sham group [12]. Another RCT compared the effect of 1 Hz real rTMS versus sham stimulation over the right pars triangularis, in 24 patients suffering of subacute stroke [28]. The tDCS was initiated 4 to 8 weeks after stroke onset. Each of the 6 daily stimulation sessions was followed by a robot-assisted arm training. Motor arm function was assessed with the Fugl-Meyer motor score and language impairment with the AAT. The motor function improved in all patients (in a significant manner in 3 cases), and aphasia improved in 4 patients [28]. Hesse and colab. evaluated the role of anodal tDCS on the ipsilesional side in the recovery after stroke in 10 patients [29]. In all patients, the reference electrode was placed on the contralateral supraorbital region, the sessions of stimulation lasted 30 min/ day for 10 days and were completed by online SLT. The application of Korean-Western Aphasia Battery evidenced a significant improvement in auditory verbal comprehension after right cathodal tDCS compared to sham and left anodal tDCS, with an overall improvement in Aphasia Quontient and spontaneous speech across groups [29]. In 2011, You and collab. evaluated the role of tDCS in 21 aphasic patients with subacute stroke divided in 3 equal groups: the patients in the first group received anodal tDCS on the left Wernicke\u2019s area , the subjects from the second group received cathodal tDCS on the right Wernicke\u2019s area and the other 7 participants were sham stimulated [NIBS could be a useful therapeutic tool in the early rehabilitation after stroke. Both methods may enhance the neuroplasticity in the injured area and reestablish the balance between different regions of the brain. The association with specific motor tasks and SLT reinforces the effect of NIBS and partially restores the damaged neural networks.Larger RCTs are needed in order to confirm the effectiveness of NIBS, but the small clinical studies published so far showed encouraging results in motor and speech recovery."} +{"text": "Previous studies reported that patients in end-of-life (EOL) care may still receive aggressive treatment in the Intensive Care Unit (ICU).

We assume the current timing plan involves OPV2 cessation in 2016 followed by OPV1 and OPV3 cessation in 2019 and we compare this to alternative timing options, including cessation of all three serotypes in 2018 or 2019, and cessation of both OPV2 and OPV3 in 2017 followed by OPV1 in 2019.If Supplemtal Immunization Activity frequency remains sufficiently high through cessation of the last OPV serotype, then all OPV cessation timing options prevent circulating vaccine-derived poliovirus (cVDPV) outbreaks after OPV cessation of any serotype. The various OPV cessation timing options result in relatively modest differences in expected vaccine-associated paralytic poliomyelitis cases and expected total of approximately 10\u201313 billion polio vaccine doses used. However, the expected amounts of vaccine of different OPV formulations needed changes dramatically with each OPV cessation timing option. Overall health economic impacts remain limited for timing options that only change the OPV formulation but preserve the currently planned year for cessation of the last OPV serotype and the global introduction of inactivated poliovirus vaccine (IPV) introduction. Earlier cessation of the last OPV serotype or later global IPV introduction yield approximately $1 billion in incremental net benefits due to saved vaccination costs, although the logistics of implementation of OPV cessation remain uncertain and challenging.All countries should maintain the highest possible levels of population immunity to transmission for each poliovirus serotype prior to the coordinated cessation of the OPV serotype to manage cVDPV risks. If OPV2 cessation gets delayed, then global health leaders should consider other OPV cessation timing options. The Global Polio Eradication Initiative (GPEI) continues to make progress toward the primary goal of interrupting all global transmission of the three wild poliovirus (WPV) serotypes . After aOPV comes in different formulations. Trivalent OPV (tOPV) protects against all three serotypes and represents the current vaccine of choice for OPV RI and the vaccine used for SIAs up until 2004. In 2005, the GPEI began using serotype 1 monovalent OPV (mOPV1) and later some serotype 3 (mOPV3) for some SIAs, because of their higher seroconversion for the mOPV serotype than achieved by the same serotype component of tOPV, particularly for the first dose , 16. In The inactivated poliovirus vaccine (IPV) currently represents the only vaccine alternative to OPV. While the killed, injectable IPV provides very good individual protection from paralytic poliomyelitis and boosts intestinal immunity in individuals with immunity from a prior live poliovirus infection , it does not protect as well against asymptomatic participation in poliovirus transmission\u00a0as OPV, particularly in settings with more intense fecal-oral transmission, and it does not spread beyond the vaccine recipient \u201328. ConsRecognizing the risks associated with OPV2 cessation, the GPEI established 6 prerequisites for OPV2 cessation, including the need to validate the elimination of persistent cVDPV2s , which rWe use an integrated global model of long-term poliovirus risk management options described in detail elsewhere .

With only a small number of paralytic cases from WPV1 remaining in the model during the first year of the time horizon , VAPP cases represent the main source of paralytic poliomyelitis in the model for 2015\u20132019.

Most scTable\u00a0The INBs represent a more informative metric for this analysis. OPV23 cessation in 2017, OPV123 cessation in 2019, and OPV123 cessation in 2019 with tOPV-only from 2017 all result in the same expected financial costs for vaccination as the current timing plan because they involve different OPV formulations without affecting the overall duration of OPV or IPV use in any of the income levels. Thus, for these alternative OPV cessation timing options the incremental costs reflect only treatment costs (or savings) associated with additional incurred (or prevented) paralytic cases. Given the relatively small number of paralytic cases involved in any of these options, their INBs remain close to 0. The INB estimate of approximately -$4.5 million for OPV123 cessation in 2019 (with or without tOPV-only from 2017) suggests that if the excluded logistical costs of coordinating OPV cessation once instead of twice amount to more than $4 million , then some economic justification exists for this original path of coordinated OPV cessation of all three OPV serotypes. OPV123 cessation in 2019 with tOPV-only from 2017 yields almost the same INBs as OPV123 cessation in 2019, which involves some continued bOPV SIAs , because the cases would occur for all OPV cessation timing options. However, longer transmission of WPV1 and/or cVDPV2 will affect the feasibility of some of the options and expected SIA frequency and costs. Some reduction in SIA frequency may remain sufficient to keep population immunity high enough to avoid cVDPVs after OPV cessation, although too much reduction or inconsistency in SIA quality would result in cVDPVs , and insOur analysis leads to the realization that flexibility in national vaccine licensing for the transition period may prove helpful. While under the current plan the GPEI continues to encourage countries to pursue licenses of bOPV for RI use after OPV2 cessation, our analysis suggests potential value in simultaneously pursuing national licenses for RI use of bOPV or mOPV1, and potentially also securing licenses now to use any mOPV serotype for outbreak response if ever needed. In addition, given uncertainty about the status of population immunity for serotype 2, our results underscore the importance of developing contingencies with manufacturers to continue tOPV production past the current planned OPV2 cessation target of April 2016.All countries should maintain the highest possible levels of population immunity to transmission for each poliovirus serotype prior to the coordinated cessation of the OPV serotype. If OPV2 cessation gets delayed, then global health leaders should consider other OPV cessation timing options."} +{"text": "The fat signal can lead to misinterpretation and poor visualization of epicardial enhancement.

In conclusion, application of synbiotic Biomin Imbo, as a feed-additive adjuvant promotes acquired humoral immune responses of broiler chickens. Increased susceptibility of birds to avian pathogens in intensive husbandry system has emphasized on necessity of improvement of innate and specific immune responses of birds by the fast establishment of a beneficial microflora and immune stimulator factors to guarantee healthy and low-price products. During this study, 192 one-day-old broiler chicks (Ross-380) in four groups with three replicates per group were used to investigate effectiveness of synbiotic Biomin Imbo on immune responses of the chickens following routine vaccination against Newcastle disease (ND), avian influenza (AI), infectious bronchitis (IB) and infectious bursal disease (IBD). The results of this study indicated that supplementation of Biomin Imbo in diet enhanced humoral immune responses significantly in the case of ND, IB, IBD ( Finding novel antigens as well as adjuvants is the most beneficial methods to induce an optimal protective immunity against human1 and poultry diseases including avian infectious bronchitis (IB), infectious bursal disease (IBD), Newcastle disease (ND) and avian influenza (AI) which cause significant economic losses in poultry industry worldwide.2,3 Interest in the dietary use of prebiotics and probiotics blossomed in the late 1800s/ early 1900 and the growing enthusiasm on the beneficial effects of pre-, pro- and synbiotics was motivated near the turn of the 20th century.4 Ban of antibiotic growth promoters (AGPs) due to increased bacterial resistance and drug residues in poultry production together with consumer's demand for \"natural\" products have encouraged findings of alternatives for AGP. In order to preserve gut microbiota and to promote host innate defenses, administration of synbiotic as alternative approach for promoting of performance and immune responses in modern poultry husbandry widely accepted.5,6 Probiotics affect the intestinal microbial balance and subsequently improve performance and reduce mortality in broiler chickens.7,8 Probiotics also protect chickens against avian pathogens,9,10 activate immunocytes and stimulate systemic immune responses11 including promoting the endogenous host defense mechanisms12 and enhancement of production natural antibodies13 as well as specific antibodies.14 On the other hand, prebiotics may control or manipulate microbial composition and/or activity, therefore combination of probiotics and prebiotics improve the survival rate of probiotics in digestive tract contributing to the stabilisation and/or enhancement of the probiotic effects.15,16 Under the present circumstances, improvement of post-vaccination immune responses against the most economically important poultry diseases, in particular IB, IBD, ND and AI is topic for research. Ideologically, synbiotics would have more beneficial effects than these elements alone.17-20 Therefore, the present project was undertaken to study the immuno-modulatory effects of the synbiotic Biomin Imbo on antibody responses during a routine vaccination of broiler chickens against IB, IBD, ND and AI as well as to compare its immunomodulatory effectiveness in vaccination with live and killed vaccines.In the 21Chickens and experimental design. One hundred and ninety-two one-day-old broiler chicks (Ross-308 strain) were randomly allocated into four groups: (A) vaccinated + diet containing Biomin Imbo, (B) vaccinated + diet not-containing Biomin Imbo, (C) environmental control (unvaccinated + diet without Biomin Imbo), and (D) Biomin control (unvaccinated + diet containing Biomin Imbo). Three replicates were considered for each group (16 chicks per replicate). After leg labeling, the chicks of each replicate were housed in separated boxes and nutritional requirements , ambient temperature, lighting, ventilation as well as other environmental conditions fully met the requirements laid down in the technical instructions of Ross-308 broiler management.21 Vaccinated groups (A and B) and unvaccinated groups (C and D) were kept in separated houses.Enterococcus facium IMB 52; 5 \u00d7 1011 CFU per kg), cell wall fragments of useful micro-organisms, prebiotic (fructo-oligosaccharides) and phycophytics was used as recommended by manufacturer . Synbiotic Biomin Imbo containing of probiotic level (below log2-3), chickens of the groups A and B were vaccinated and on 11-days and second vaccination (only live vaccine) was carried out on 21-days of age using clone 30 strain of ND virus by eye-drop route as a recommended route inducing higher antibody titer with the closest-rang.22 In the case of AI, one vaccination is carried out on 11-days-old using killed (H9N2) vaccine by subcutaneous injection as a routine vaccination for broilers in the region. In the case of IBD, optimal time for first vaccination was estimated3 and D78 vaccine was used on day 16 and repeated on day 24 of age (based on MDA of the chicks). In the case of IB, as protection significantly (p < 0.05) correlated with levels of local respiratory antibody and not with serum antibody23 therefore, regardless to the potential negative effects of MDA against IB virus, Ma5 vaccine was used via eye-drop for vaccination of one-day-old chicks against IB on day 1 and is repeated on day 18 of age using the same vaccine.2,24Sampling. As level of MDA titer is very important for determination of the best timing of vaccination against IBD as well as ND. On day 1 (one-day-old chicks), blood samples were collected from half the chicks of each replicate as previously described.25,26 On day 7 and then at weekly intervals until 42 days of age, blood samples were collected from jugular veins and brachial vein, respectively as previously described.27,Serum antibody titers assessment. Antibody level was determined using weekly serum samples of each bird separately in each replicate and treatment. Hemagglutination inhibition test (HI) was used for evaluation of antibody titers against ND and AI, as it has been reported that HI test is an excellent indicator of the immune status and disease resistance of a flock especially to assess protective response following vaccination,27,28 while the indirect enzyme-linked immunosorbent assay was used for evaluation of antibody titers as recommended for IB29 and IBD.3,29,30Statistical analysis. SPSS software was used for analyzing of the results under completely randomized design employing one-way ANOVA analysis of variance and the means of different treatments were compared with Bonferroni, Duncan multiple range and repeated measure tests.

Status of MDA and acquired antibody titer against avian infectious bronchitis are shown in nd vaccination and peaked around 42 day of age. In comparison to groups A and B (vaccinated groups), antibody titers of chickens treated with Biomin Imbo (group A) differed significantly (p = 0.020) from those of group B during day 28 to end of experiment antibody titer than those of vaccinated but not treated with Biomin Imbo diet. 31,32 but also leads to immuno-modulation of humoral immune responses as well as cellular immune responses,33 however debates on their potential side effects (cytotoxic and moderate genotoxic effects) is open.34 Comparison of a growth promoters, prebiotics, probiotics as well as synbiotics on their preventive effects in colonization of salmonella in poultry revealed that antimicrobial agents allowed higher colonization as compared to prebiotics and probiotics,9 but Biomin controls the intestinal colonization of Salmonella enteritidis in chickens.35In general, dietary supplementation of synbiotic Biomin Imbo not only ameliorate performance of poultryEnterococcus faecium) of Biomin Imbo enhances humoral immune responses against sheep red blood cells (SRBC).36 Biomin Imbo also increases most parameters of blood profile including total protein37 and higher protein promotes induction of specific antibody titer against avian pathogens. Dietary inclusion of synbiotic Biomin Imbo increased growth performance and improved intestinal morphology, nutrient absorption38 and resistance of birds to pathogens or diseases.37 Comparison of the synbiotic with another probiotic indicated that the synbiotic had much more beneficial effects than probiotic alone5 as well as prebiotics alone39 or AGP alone.40 Enhanced effects of Biomin Imbo on antibody titers of the chickens against ND, AI, IB and IBD were observed during this study and is in agreement with previous reports that the serum antibody responses to oral and systemic administration of antigens were significantly enhanced by probiotics supplementation.41 Due to the immunomuadulatory effects of vitamin E, future synbiotics may include vitamin E as well.42With regards to immunomodulatory effects of Biomin Imbo, there are some reports that probiotic (nd vaccination). Analyzing of the results, as shown in p = 0.100) until 21 day of age; b) From day 21 up to end of the experiment, difference between vaccinated and unvaccinated groups due to vaccination was significant (p = 0.010); c) Comparison between antibody titers of chickens of group A (vaccinated and treated with Biomin Imbo) and those of chickens of group B (vaccinated but not treated with Biomin Imbo) was significant on the day 35 (p = 0.049) and on the day 42 (p = 0.048) of age. Continuously reduction of ND antibody titer of chickens of unvaccinated groups (C and D) and its remaining at undetectable level during experimental period confirmed that neither environmental nor cross contamination had occurred. Antibody titers of vaccinated chickens (groups A and B) increased following first vaccination (live + killed) and reached the highest level on day 35 of age is the highest available titer that could be induced by vaccinations (two live + one killed vaccines) as mean titers 4 to 6 log2 for single live and at least log2-8 for live plus killed vaccine was reported by OIE.43 Higher ND titers of chickens treated by Biomin Imbo is observed in our study is also in agreement with those of log2-7.2 and mean titer of log2-7.5 was reported for mentofin treated chickens.44 The beneficial effects of Biomin Imbo could be more evident in undesirable circumstances due to intensive husbandry systems. However, the enhancement effects of Biomin Imbo on humoral immune responses against ND observed during this study is also been reported for an another probiotics14 as well as other synbiotics.The results obtained during this study is in agp = 0.150) until 21 day of age; b) From day 21 up to end of the experiment, difference between vaccinated and unvaccinated groups due to vaccination was significant (p = 0.020); c) Difference between group A (vaccinated and treated with Biomin Imbo) and group B (vaccinated but not treated with Biomin Imbo) was not significant (p = 0.160). Regarding lack of significant increasing effects of Biomin in the case of AI, it may be attributed to the mechanism of this product on providing a better condition for multiplication of live vaccines whereas a killed vaccine was used in the case of AI. High antibody titers observed during this study (-5.6) of chicken group A could be attributed to enhancement effects of Biomin Imbo on antibody titers of the chickens as it has been reported that optimal nutritional status may enhance immune function indicated by increased vaccine response following vaccination against influenza.37,45As shown in is study for chic24 As shown in p < 0.05).33 As maternal IBV antibodies are in low concentrations in the tear secretions than in sera, therefore, the interference between MDA and virus of vaccine may happen in a very low level. However, in the eye-drop or spray routes, invasion of the gland by virus of vaccine without the involvement of blood borne circulation after infection by the conjunctival and intranasal routes, would explain why the high levels of MDA of one-day-old chicks did not impair immunization.46 Lack of rising of antibody titers of unvaccinated chickens (groups C and D) during experimental period indicated that there was neither environmental nor cross contamination. Late rising of antibody titer (28 days post-1st vaccination and 10 days post-2nd vaccination) of the vaccinated chickens (groups A and B) and reaching the highest level at six weeks age were observed during this study is in agreement with the studies reporting that antibody peaked around 45 day of age following vaccination on day 1 and on day 25. Our observation on enhancement effects of Biomin Imbo on humoral response against IB is in agreement with the results reported for an another synbiotic.33 Recent studies indicate that supplementation of vitamin E may also enhances higher immune responses against IB.42Humoral immunity has a key role in protection of chickens against IB.3 Maternally-derived antibody transferring rate (up to 73.00%) from breeders to yolk/chicks not only varied among different chickens' line but also MDA varied among one-day-old chicks even from same broiler breeder flock47 and depending on the range of MDA, finding optimal timing of primary vaccination would be too difficult. Although there are several methods for predicting the timing of initial vaccination,30,48 in routine vaccination program for intensive poultry husbandry system, primary vaccination against IBD may equalized MDA of the chicks and good immune response may be obtained following booster dose. Generally, infectious bursal disease with clinical signs occurs around three to six weeks of age3 and the birds are most susceptible at 30 to 35 days old. Therefore, an ideal vaccination program must induce protective antibody titer at this age as occurred during this study Differences among the groups were not significant (p = 0.100) until day 28 of age; b) From day 28 up to end of the experiment, difference between vaccinated and unvaccinated groups due to vaccination was significant (p = 0.020); c) Difference between group A (vaccinated and treated with Biomin Imbo) and group B (vaccinated but not treated with Biomin Imbo) was significant (p = 0.036) only on day 42 of age. Humoral antibody plays a key role in protection against IBD.is study and IBD In conclusion, Application of synbiotic Biomin Imbo enhances antibody responses following vaccination against ND, AI, IB and IBD but it is more effective in live than killed vaccines and could be used as a feed-additive adjuvant for improving innate and acquired immune responses in chickens."} +{"text": "We also update the information about the inhibition properties of single pgip gene products against microbial PGs and the results, including field tests, showing the capacity of PGIP to protect crop plants against fungal, oomycetes and bacterial pathogens.Polygalacturonase inhibiting proteins (PGIPs) are cell wall proteins that inhibit the pectin-depolymerizing activity of polygalacturonases secreted by microbial pathogens and insects. These ubiquitous inhibitors have a leucine-rich repeat structure that is strongly conserved in monocot and dicot plants. Previous reviews have summarized the importance of PGIP in plant defense and the structural basis of PG-PGIP interaction; here we update the current knowledge about PGIPs with the recent findings on the composition and evolution of To this end, pathogens produce a wide array of plant cell wall degrading enzymes (CWDEs), among which endo-polygalacturonases are secreted at very early stages of the infection process . Most of these genes have been identified as pgip genes on the basis of sequence identity but only a few of them have been shown to encode proteins with PG-inhibitory activity.Early characterization of a polygalacturonase-inhibiting activity was reported in 1970s . These proteins do not interact in vitro, although VvPGIP1 reduces symptoms caused by BcPG2 upon co-infiltration in leaves. The number and sources of PGs tested is also limited; only a few studies have been carried out against PGs of bacteria and insects possessing non functional pgip genes . Recently, a wheat gene with some sequence similarity to pgip genes has been reported and was shown to be involved in the defense response against Fusarium graminearum forms with PG from A. niger (AnPGII), F. phyllophilum (FpPG) and C. lupini (ClPG). Site-directed mutagenesis has shown that the residues involved in the interaction are located in the concave surface of the inhibitor suggesting that the protein is highly versatile in recognizing different epitopes of various PGs Bnpgip1 or Bnpgip2. Arabidopsis plants overexpressing Atpgip1 or Atpgip2 showed a significant reduction of disease symptoms caused by B. cinerea PGIP (PcPGIP) capable of inhibiting the PGs secreted by B. cinerea, showed a reduction of disease lesions caused by this fungus both on ripening fruit (15% reduction) and leaves (about 25% reduction). The initial establishment of infection was not affected in the transgenic plants but the later colonization of the host tissue was significantly reduced , Vvpgip1 (from V. vinifera), Capgip1 [from pepper (Capsicum annum)] and Brpgip2 (from B. rapa) have been obtained in transgenic tobacco. Plants expressing PvPGIP2 showed about 35% reduction of symptoms caused by B. cinerea that are highly resistant to blue mold disease.

Using RNA-Seq, we examined the seed coat transcriptome from three stages of immature seed development in two pairs of isolines with normal or defective seed coat phenotypes due to the net pattern. The genome-wide comparative study of the transcript profiles of these isolines revealed 364 differentially expressed genes in common between the two varieties that were further divided into different broad functional categories. Genes related to cell wall processes accounted for 19% of the differentially expressed genes in the middle developmental stage of 100\u2013200 mg seed weight. Within this class, the cell wall proline-rich and glycine-rich protein genes were highly differentially expressed in both genetic backgrounds. Other genes that showed significant expression changes in each of the isoline pairs at the 100\u2013200 mg seed weight stage were xylem serine proteinase, fasciclin-related genes, auxin and stress response related genes, TRANSPARENT TESTA 1 (TT1) and other transcription factors. The mutant appears to shift the timing of either the increase or decrease in the levels of some of the transcripts. The analysis of these data sets reveals the physiological changes that the seed coat undergoes during the formation of the breaks in the cell wall.The plant cell wall performs a number of essential functions including providing shape to many different cell types and serving as a defense against potential pathogens. The net pattern mutation creates breaks in the seed coat of soybean ( Plant cells are surrounded by cell walls which provide tensile strength, mechanical support, protection from insects and pathogens, prevention of water loss, and that participate in cell to cell communication Glycine max) has been well characterized, and contains features in common with the majority of the legumes: an epidermal layer of palisade cells, or macrosclereids, a sub-epidermal layer of hourglass cells, or osteosclereids, a few layers of parenchyma, and an aleurone layer The seed coat, or testa, of the mature soybean of the cell wall leading to higher levels of this transcript in the defective seed coats at the middle weight range of 100\u2013200 mg seed weight The effect on PRP1 transcript levels was assumed to be a downstream effect of the net pattern mutation. In this report, we present the global gene expression analysis of the net pattern cell wall mutant in soybean using transcriptome analyses of three different stages of seed development at 50\u2013100 mg, 100\u2013200 mg, and 400\u2013500 mg. By comparing RNA-Seq data from the two lines containing the defective seed coat trait compared to their standard counterpart isolines using Bowtie alignments The isolines in the background of cultivar Clark are referred to as Clark standard (CS) which exhibits an intact seed coat and Clark defective (CD) that contains the defective seed coat mutation that had been backcrossed into the Clark standard line. Likewise, Harosoy standard (HS) is compared to the Harosoy defective (HD) isoline that contains the defective seed coat mutation. The genotypes and phenotypes of these two isoline pairs is presented in Next-generation high throughput sequencing of the transcriptome (RNA-Seq) was used and the cDNA libraries were constructed from seed coats from 50\u2013100 mg, 100\u2013200 mg and 400\u2013500 mg seed weight stages in standard and mutant isolines of Clark and Harosoy cultivars. Each library was sequenced on the Illumina GAII or HiSeq 2000 platforms. The number of raw sequence reads obtained from all four isolines, at different seed weight stages are presented in As presented in As shown in A selection of 29 of the 364 differentially expressed genes at the 100\u2013200 mg seed weight stage are shown in As presented in The expression levels of PRP1 and PRP2 at different seed weight stages were previously demonstrated by The graphical representations of the expression levels of the other differentially expressed genes shown in It is clear from the 68 graphs of the gene expression patterns shown in There were 21 hormone regulated genes that were differentially expressed in the seed coat of wild type and defective isolines of both Clark and Harosoy background includinThe expression pattern of two other hormone regulated genes in ie., if expression of a particular gene was higher in the standard isoline of Clark, then it was lower in the standard isoline of Harosoy) .Two zinc finger domain (C2H2 type) containing protein genes that had TT1 (TRANSPARENT TESTA1) annotations were approximately 6-fold and 15-fold more highly expressed in the defective seed coats of the Clark and Harosoy lines, respectively, at the 100\u2013200 mg seed weight stage & 4. TheAlong with the two TT1 gene models, there were 14 total transcription factor genes that showed differential expression in seed coats of standard and defective isolines in both of the Clark and Harosoy backgrounds at the 100\u2013200 mg stage . The mosWe provide an overview of the genes that are affected by the \u201cnet pattern\u201d mutation which affects the structural integrity of the soybean seed coat. As shown in Allergens, thaumatin-like proteins, and cysteine-rich domain containing proteins have also been reported to play important roles in various functions related to the cell wall While we have concentrated on the 51 cell wall related genes that were significantly differentially expressed in both varieties, we note that there are 920 additional cell wall related genes that did not show differential expression in the seed coats of either of the two isoline pairs. Thus, there are many processes related to the cell wall that are not affected at the transcript level by the net-pattern mutation.Auxin is a plant growth regulator that is required for cell expansion, division and differentiation. Auxin pathway related genes have been reported to regulate several cell wall related genes in Arabidopsis Glycine maxThe proline-rich proteins are composed of small tandem repeats such as PPVYK or PPVEK, where the second proline is often hydroxyproline I alleles), as compared to black Clark isolines . LikewisOur RNA-Seq data show excet al., WRKY transcription factors are involved in regulation of downstream genes encoding the NAM, ATAF1/2, and CUC2 (NAC) and CCCH type (C3H) zinc finger TFs that activate secondary wall synthesis Arabidopsis thaliana, these were expressed in specific cell types of roots, stems and seeds that undergo suberization Transcription factors are important players for controlling the flow of genetic information from DNA to RNA and ultimately affecting the growth and physiology of the plant. In this study, there were approximately 240 differentially expressed transcription factor genes at different seed weight stages \u2013S4. ThesIt is likely that the defective seed coat mutation in soybean sets in motion changes in many pathways related to the cell wall. Some of the differential expression may be a temporal shift in developmental appearances of transcripts. Notably, in the case of the TT1 homolog, it appears that the decline in its transcript levels was delayed in the defective seed coats relative to the standard seed coats , thus leGlycine max. There were approximately 1300 significantly differentially expressed genes affected by this mutation in each isoline pair with 364 in common between the two isolines of different genetic backgrounds. The cell wall structural protein genes including proline-rich proteins (PRP1 and PRP2) and glycine-rich proteins were among the transcripts affected by the mutation as well as a number of transcription factors. Some of the transcript patterns indicate that a developmental shift in timing of gene expression underpins the differential gene expression changes at mid-maturation as shown by graphical presentation of expression patterns for 82 out of 364 genes that were significantly differentially expressed in both the Clark and Harosoy backgrounds. In summary, the mutation appears to set in motion a complex series of events, many manifested at the transcript level, that lead to changes in physiology and ultimately structure of the cell wall. The information on potential candidate genes for this mutation and the regulated genes will not only be helpful in understanding cell wall physiology in soybean, but could also provide a platform for improvement in bioenergy crops like sorghum, maize and Miscanthus.We present an overview of genes whose expression was affected by the \u201cnet pattern\u201d mutation in soybean. Two isolines of different genetic backgrounds were used to understand physiology related to this mutation that causes defective cracks in the seed coats. Twelve samples representing three stages of seed coat development from each of the four lines were subjected to the power of next-generation sequencing to obtain millions of transcript reads that were mapped to all 78,773 high and low confidence gene models of Glycine max used in this study were a black seeded Clark line, Clark defective seed coat, Harosoy standard and Harosoy defective seed coat. The defective seed coat mutation was originally found in two PI (plant introduction) lines, PI 339.994 and PI423.730B and these lines were backcrossed to the black seeded Clark line (UC9) to create an isoline UC412 containing this mutation. The same mutation was also backcrossed into the Harosoy line to create an isoline UC508. The L or PI numbers represent the official USDA isoline or plant introduction numbers, respectively. The UC number is an internal number used by our laboratory. Detailed information on these lines is presented in The isolines of For RNA extraction, immature seeds were harvested over the course of several weeks. The individual seeds were pooled and sorted by weight. Following this, each seed was dissected, separating the cotyledon and embryo from the seed coat, and placed in separate 15-ml polypropylene centrifuge tubes . All tissue was then frozen in liquid nitrogen and placed in storage at \u221280\u00b0C until it could be lyophilized. RNA of seed coats of seeds from the 50\u2013100 mg, 100\u2013200 mg and 400\u2013500 mg seed weight stages of each isoline was extracted separately using the RNA for 5 ml volumes from \u223c30 mg (50\u2013100 mg and 100\u2013200 mg seed weight stage) and \u223c70 mg (400\u2013500 mg seed weight stage) dry weight.

RBV inhibits inosine 5\u2032-phosphate dehydrogenase (IMPDH), the enzyme required for synthesis of guanosine monophosphate (GMS) as well as DNA and RNA synthesis. Based on this mechanism of action, RBV is also used in the treatment of solid tumors, lymphoproliferative disease and some inflammatory diseases such as Crohn's disease. A number of nucleoside analogs including RBV diffuse across cell membranes through a membrane transporter protein called equilibrative nucleoside transporter-1 (ENT1). Our recent publication demonstrated that an autophagy response induced by hepatitis C virus (HCV) in a cell culture reduces RBV uptake and antiviral activity by diminishing the surface expression of ENT1 [Human ENTs are the nucleoside transporter proteins expressed on the cell membrane that occur as four isoforms ENT1-ENT4). These proteins play important roles in transporting nucleosides- and nucleotides-based small molecule drugs. The expression of ENT1 is critical for salvage of natural nucleotides and nucleosides for nucleic acid synthesis, neurotransmission, and regulation of cardiovascular activity . The exp. These pTaking into consideration the previously mentioned autophagy related mechanism that regulates the expression of ENT1, it is reasonable to speculate that cellular autophagy status could regulate the uptake and response to nucleoside based treatment of viral infection or cancer.

The decreased antiviral activity of RBV against virus disease could be related to the degree of cellular autophagy response and expression of ENT1.

Hypertrophic cardiomyopathy (HCM) is a relatively rare inherited cardiovascular disease that affects approximately 1 in 500 young individuals and that accounts for 35% of sudden cardiac death cases in young athletes and myosin binding protein C (MYBPC3) are the most commonly involved genes, followed by troponin I (TNNI3), troponin T (TNNT2), essential myosin light chain (MYL3), regulatory myosin light chain (MYL2), alpha tropomyosin (TPM1), and cardiac actin (ACTC) . Myocardial deformation analysis in the form of magnetic resonance imaging (MRI) has revealed strain dissimilarities between the endocardial and epicardial layers of the left ventricle (LV) wall and among different LV segments or slow (MYH7). There are certain developmental, environmental, epigenetic and hormonal factors that regulate the expression of MYH6 and MYH7, which are encoded by a gene cluster on chromosome 14 Gupta, . MYH7 isSeveral studies have examined the mechanical properties of the epicardial and endocardial layers . In general terms, patients with unexplained syncope, documented ventricular tachycardia or aborted SCD, positive family history for SCD, maximal LV wall thickness >30 mm and abnormal drop in blood pressure during exercise, treated with an implantable defibrillator . The mechanisms analyzed in this paper shed some light on the relation of mutations to disease phenotype, although they may not necessarily apply to all patients. A better understanding of the pathophysiological mechanisms leading to hypertrophy will contribute to the further improvement of treatment and to risk stratification for sudden cardiac death.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "AbstractReduced fetal growth is seen in about 10% of the pregnancies but only a minority has a pathological background and is known as intrauterine growth restriction or fetal growth restriction (IUGR / FGR). Increased fetal and neonatal mortality and morbidity as well as adult pathologic conditions are often associated to IUGR. Risk factors for IUGR are easy to assess but have poor predictive value. For the diagnostic purpose, biochemical serum markers, ultrasound and Doppler study of uterine and spiral arteries, placental volume and vascularization, first trimester growth pattern are object of assessment today. Modern evaluations propose combined algorithms using these strategies, all with the goal of a better prediction of risk pregnancies.Abbreviations: SGA = small for gestational age; IUGR = intrauterine growth restriction; FGR = fetal growth restriction; IUFD = intrauterine fetal demise; HIV = human immunodeficiency virus; PAPP-A = pregnancy associated plasmatic protein A; \u03b2-hCG = beta human chorionic gonadotropin; MoM = multiple of median; ADAM-12 = A-disintegrin and metalloprotease 12; PP-13 = placental protein 13; VEGF = vascular endothelial growth factor; PlGF = placental growth factor; sFlt-1 = soluble fms-like tyrosine kinase-1; UAD = uterine arteries Doppler ultrasound; RI = resistence index; PI = pulsatility index; VOCAL = Virtual Organ Computer\u2013Aided Analysis software; VI = vascularization index; FI = flow index; VFI = vascularization flow index; PQ = placental quotient Considered by the American College of Obstetricians and Gynecologists \u201cthe most common and complex problem in modern obstetrics\", fetal growth restriction still needs clear criteria because intrauterine fetal growth is not defined by clear parameters but mainly estimated on the basis of multiple factors. Research in this field is trying to find predictive parameters, with the goal of reaching an early diagnosis, which would lead to a better management of the condition [2]. Intrauterine growth restriction is defined as the pathologic inhibition of intrauterine fetal growth and the failure of the fetus to achieve its growth potential [3]. While the majority of such pregnancies will have a physiologically normal fetus that is simply small for gestational age (SGA), pathological fetal growth-restriction is a different category and the ability to differentiate such a condition from SGA is limited. A healthy fetus with estimated weight or birth weight below the 10th percentile according to population standards is commonly defined as SGA [5]. Pathological SGA is known as intrauterine growth restriction (IUGR) or fetal growth restriction (FGR). Fetal development is evaluated through comparison between estimated fetal weight or birth weight and references or standards for different gestational ages [6].Impaired fetal growth is seen in about 10% of pregnancies [ Why detecting intrauterine growth restriction?9]. IUGR is associated with increased fetal and neonatal mortality and morbidity, being linked to immediate perinatal adverse events and also to adult pathologic conditions [14]. Former studies showed that cerebral palsy was found to be 4-6 times more frequent in newborns below the 10th percentile compared to those between the 25th and the 75th percentile [15]. A strong association between FGR and stillbirth was also confirmed [16]. From the moment FGR was recognized as a cause of perinatal death, almost 50% of stillbirth were identified as FGR [17], resulting in a decrease of unexplained stillbirth from 67-70% to 15% [18]. Therefore, fetal growth impairment identification triggers a 4-time reduction in neonatal complications and death [14]. Fetal growth is known to be an important predictor of pregnancy outcome and reflects the interaction between physiological and pathological factors influencing the fetus [19]. In addition, the investigation of possible IUGR/FGR has the objective of an early detection and appropriate management that could lower the percentage of stillbirths and other perinatal complications, hoping that the identification of low risk fetuses would decrease the number of unnecessary surveillance [11]. In about 75% of the cases, IUGR remains unrecognized until birth and the diagnosis comes retrospectively, whereas in low-risk pregnancy the detection rate is about 15% [ IUGR: risk factors21]. The main factors assessed in clinical practice include: maternal factors , fetal factors , adnexal factors [22]. The risk factors for IUGR comprise a wide range of conditions and their assessment should be seriously taken into account, as they are easy to perform and are routinely used during pregnancy [23]. Further diagnostic tests could have a better relevance in a selected high-risk population [24]. However, these clinical factors have shown a different impact for each individual case and their relevance, as effective screening tools have not been proved yet [25]. A positive history for risk factors of IUGR can raise the problem of an increased surveillance with the specific goal of an early detection of growth insufficiency [26]. For this purpose, biochemical serum markers, Doppler study of uterine arteries, placental volume and vascularization as well as first trimester growth pattern, were the object of study for IUGR/FGR assessment. As presented above, IUGR/FGR is linked to serious pregnancy complications and early assessment of the condition is a main topic of research today. Furthermore, preventive measures like administration of low dose aspirin showed efficacy in IUGR treatment if administered before the 16th week of gestation [ Serum markers linked to IUGR27]. The impaired spiral artery transformation is leading to weak development of the utero-placental circulation and is implied in the pathology of preeclampsia and IUGR [21]. The placentation process starts with the migration of trophoblastic cells that invade the walls of spiral arteries and transform them from small caliber high resistant vessels into wide caliber low resistant vessels that deliver blood at low pressure to the intervillous space. Then, the utero-placental circulation develops in two stages: the first stage (until the 10th week of gestation) consists in endovascular plugging of the spiral arteries by trophoblastic cells, subsequently followed by invasion and destruction of the intradecidual spiral arteries; the second stage (between 14-16 weeks of gestation) consists in the invasion of the inner miometrial part of the spiral arteries [21]. Several serum analytes have been studied in hope of finding a relevant marker linked to IUGR, but none of them proved to be sufficiently accurate to be used in routine clinical practice as single predictive marker. The combined approach using clinical data, serum markers, biophysical parameters showed increased predictive relevance [28]. Maternal serum analytes were first studied with the aim of screening for aneuploidies during the first or second trimester of pregnancy and their use was then further extended in many studies to evaluate their utility as markers for impaired placentation. The trophoblastic invasion failure is thought to be responsible of the changes in the concentration of serum placental products [29]. Furthermore, in the group of 4390 women with singleton pregnancy evaluated by Spencer et al. in 2005 the maternal low levels of serum PAPP-A at 11-13 weeks of gestation resulted significantly associated to adverse pregnancy outcomes [30]. Low levels of PAPP-A were mentioned as predictors of IUGR also by Goetzinger et al. in 2009 and Poon et al. in 2009 . The sensitivity of detecting IUGR for a first trimester PAPP-A level below the 5th percentile ranges only between 8% and 33% and PAPP-A as single marker is an insufficient screening tool for IUGR [33]. Pregnancy associated plasma protein A (PAPP-A), an Insulin\u2013like Growth Factor Binding Protein Protease whose levels depend on placental volume and function, was assessed in several studies with congruent results. In 2000, Ong et al. evaluated 5584 singleton pregnancies at 10-14 weeks of gestation and measured maternal serum free beta human chorionic gonadotropin (\u03b2-hCG) and PAPP-A, concluding that low levels of maternal serum PAPP-A or \u03b2-hCG were associated with subsequent development of pregnancy complications [34]. Later, Gotzinger et al. showed that high levels of \u03b2-hCG were linked to SGA fetuses [31]. Overall, the predictivness of free \u03b2-hCG is unsatisfactory today [25]. Dugoff et al. evaluated 34271 pregnancies at 11-14 weeks of gestation and proved that maternal serum free \u03b2-hCG was mildly reduced in pregnancies that subsequently developed IUGR [36]. In 2008, in the name of the Genetics Committee of the Society of Obstetricians and Gynaecologists of Canada, Gagnon et al. reviewed the obstetrical outcomes associated with abnormal levels of single or multiple maternal serum markers used in the screening for aneuploidy. PAPP-A, alphafetoprotein, \u03b2-hCG, estriol, unconjugated estriol, inhibin-A were the analytes assessed and among the conclusions an unexplained low PAPP-A (< 0.4 MoM) and/or a low hCG (< 0.5 MoM) in first trimester were associated with an increased frequency of adverse obstetrical outcomes [37]. As in the first trimester biochemical screening starts as early as 8wa, the detection of a low level of hyperglycosylated human chorionic gonadotrophin correlated with a low PAPP-A and resulted a marker of impaired placentation, showing 90% specificity and 69% sensitivity when adjusted for mean arterial pressure and parity .41]. In 2007, Chaftez et al. showed that low levels of first trimester PP-13 were associated with preterm birth in women with IUGR [42]. In 2008, Spencer et al. found poor association between PP-13 and pregnancy outcome like IUGR [43]. In 2008, using the integrated assessment of PP-13, PAPP-A and uterine artery Doppler at 11-13 weeks of gestation, Poon et al. determined a 20% detection rate of FGR at a false positive rate of 5% [44]. Placental Protein 13 (PP-13) is a peptide involved in placental implantation and vascular invasion and remodeling [45]. Soluble fms\u2013like tyrosine kinase-1(sFlt-1) on the other hand, inhibits the effects of VEGF and PlGF by blocking their interaction with the specific receptors. The imbalance between the anti-angiogenic and angiogenic factors seems to be linked of preeclampsia and IUGR [45]. The recent meta-analysis performed by Conde-Agudela et al. in 2013 including 53 studies and 39974 women evaluated 37 new biomarkers among which: Angiogenesis-related biomarkers , Endothelial function/oxidative stress-related biomarkers ; Placental proteins/hormone-related biomarkers and other markers like metabolomics and genetic biomarkers. Overall, none of the 37 novel biomarkers evaluated showed a significant accuracy for predicting IUGR [45]. Angiogenic factors implied in placentation like Vascular Endothelial Growth Factor (VEGF) and Placental Growth Factor (PlGF) were also evaluated in many studies [ Ultrasound markers21]. The Doppler ultrasound sampling of uterine arteries (UAD) is a useful non-invasive method for the assessment of the interaction between fetal and maternal hemodynamic compartment. Starting from the early studies of Campbell et al. and Trudinger et al. in the 1980s, this procedure has been reported in numerous following surveys and showed to be a promising technique for the prediction of the IUGR risk [46-48]. In case of an incomplete trophoblastic invasion of the spiral arteries, the maternal compartment failsed to transform from a high resistance to a low resistance flow district and this impairment is associated with the development of preeclampsia and IUGR. In these cases, a Resistence Index (RI) or a Pulsatility Index (PI) above the 90th-95th percentile and/or the presence of unilateral or bilateral notching is associated with a value of the RI >0,58 or a value of the PI >1,45 [49]. Therefore, in 1994 North et al. and in 1998 Irion et al. stated that UAD was not a reliable screening test for nulliparous women [51]. Further studies performed in the 2000s have evaluated UAD between 10-14 weeks of gestation finding low positive predictive values for IUGR and a slightly better prediction value for preeclampsia with IUGR or IUGR alone with delivery in less than 32 weeks [55]. Most of the studies published to date, disregarding if performed during the first or second trimester, agree that UAD modifications are linked to IUGR but are not a reliable single predictive marker for defining a low risk category [56]. An interesting approach proposed by Gomez et al. in 2006 showed that the sequence of changes in the uterine flow between the first and second trimester correlates with subsequent appearance of IUGR and the highest risk is held by women with persistent low vascular indices [54]. The early studies that assessed UAD were performed during the second trimester of gestation, between weeks 18-23 [49-54]. Although an increased resistance in the uterine arteries is associated with poor obstetric outcome like preeclampsia, IUGR or prematurity, the positive predictive value was found to be only 15% for IUGR [57]. Hung et al. evaluated color and spectral Doppler of the spiral arteries between 13-19 weeks and 20-25 weeks concluding that spiral artery Doppler assessment was not a sensitive tool for detection of IUGR in a low risk population [58]. Furthermore, in studies comparing normal outcome pregnancies versus complicated pregnancies, spiral arteries sampling failed to show any statistically significant predictive value, making spiral arteries Doppler study an insufficient method for screening of IUGR [59].Spiral arteries have been subjected to assessment during the first trimester. M\u00e4kikallio et al. found that spiral arteries impedance decreased starting with the 5th week of gestation and uterine and arcuate artery lost their tonus starting with the 8th week .62]. In a region of interest, three indices are mostly calculated and used: Vascularization Index (VI): the ratio between color vessels and total vessels , representing the percentage of blood vessels in a region of interest; the Flow Index (FI): the sum of a color vessel\u2019s signal intensity divided by the number of color vessels, representing the amount of blood corpuscles in the vessels in a region of interest; the Vascularization Flow Index (VFI): the ratio between the sum of the color vessel\u2019s signal intensity and the total tissue vessels, representing the total number of blood corpuscles in the total tissue volume. In 2004, Merce et al. showed that the 3D-Power Doppler study of the placental vascularization in normal pregnancies is reproducible and seems to be a useful tool in performing \u201ca placental biopsy\" [63]. In 2008, Guiot et al. used this technique in the assessment of the 3rd trimester pregnancies complicated with IUGR and compared them to normal pregnancies, correlating VI, VFI and FI values to Umbilical Artery Doppler abnormalities (elevated Systolic/Diastolic ratios and absent End Diastolic Velocity), and the results showed that modifications in vascularization indices could be detected earlier than Umbilical Artery Doppler abnormalities [64]. In 2009, Noguchi et al. performed \u201cplacental vascular sonobiopsies\" starting with the second trimester, comparing normal and growth restricted pregnancies and proving the differences in vasculature [65]. Against these evidences, in vitro phantom studies performed by Raine-Fenning et al. and Schulten-Wijman et al. in 2008 questioned the technical and methodological aspects of this procedure, doubting the reproducibility\u00ac\u00ac\u00ac\u00ac [67]. On the other side, the sheep model study conducted by Olivier Morel et al. in 2010 demonstrated a good correlation between true uterine blood flow and flow parameters, as well as a good reproducibility of the technique [68]. The introduction of Virtual Organ Computer\u2013Aided Analysis software (VOCAL) proved useful in the quantification of blood vessel volume and of the flow in an acquired volume [69]. Another way of determining early fetal growth was proposed by Hafner et al. who compared Placental Quotient (PQ) [Placental Volume / Crown Rump Length] assessed during the first trimester with Uterine Artery Doppler at 22 weeks and concluded that PQ has low sensitivity in diagnosis of IUGR in low-risk population, comparable with that of Uterine Artery Doppler, but has the advantage of possible first trimester assessment [70]. In 2013, these authors refined their research showing that Placental Bed Vascularization Index assessed by 3D Power Doppler could be used for a quick and reliable first trimester assessment of severe pregnancy risks because it shows a 66,2% detection rate for severe pregnancy complications, higher than the 50% sensitivity of second trimester Uterine Artery Doppler [71]. In regard to placental volume assessment Rizzo et al. showed in 2009 that first trimester evaluation of placentas in a high risk group with low PAPP-A proved a good correlation between reduced placental volume and low fetus weight (<10th percentile) with Umbilical Artery Doppler modifications [ The multiparameter approach21]. The combined approach reflects various pathological pathways: Doppler ultrasound of the uterine arteries shows inadequate invasion of the spiral arteries and impaired secretory placental function is reflected by the disturbances of biomarker levels [72]. Preeclampsia is associated with IUGR and models of prediction by combining ultrasound assessment of uterine arteries, biochemical markers and maternal history were published concerning the assessment of both conditions, but the need for the development of a model for prediction of SGA without preeclampsia emerged [74]. With the purpose of identifying SGA fetuses not related to preeclampsia, Karagiannis et al. used a model of prediction containing Uterine Artery Doppler Pulsatility Index at 11-13 weeks of gestation, Mean Arterial Pressure, maternal serum PAPP-A, free \u03b2-hCG, Placental Growth Factor, PP-13, ADAM-12 and Fetal Nuchal Translucency. Although the study did not distinguish between the constitutional and pathological SGA, it raised the problem of increased surveillance for the whole population at risk for SGA, improving perinatal outcome by individualized management in late-second trimester and third trimester. The study also proved a good detection rate for SGA of 73% for those requiring delivery before 37 weeks and of 46% for those requiring delivery after 37 weeks [28]. Investigators tried to improve the prediction of IUGR by combining Doppler indices with biochemical and clinical parameters due to the insufficient predictive value of each marker alone [26]. A thorough history should be taken to all pregnant women at the first antenatal visit because risk factors determination results are easy and inexpensive. Different single approaches in the screening of this condition have been proposed but did not show sufficient sensitivity, therefore, combined models are proposed with the goal of a better predictive value. Large-scale prospective studies are required to prove the power of such integrated approaches in clinical practice.Although it is a public health problem with around 10% incidence in the pregnancy population, FGR is still a matter of debate starting from the definition, the multifactorial origin, the low levels of prediction, the questionable references like customized or uncustomized growth charts, and the methods of diagnosis and management. The main trajectory of research is towards the first trimester diagnosis, as the optimal interval in which a prophylactic treatment would influence placentation ends in the 16th week ["} +{"text": "However, the exact mechanisms of the selectivity and toxicity have remained obscure. Here we discuss the current knowledge on the role of mutSOD1 in mitochondrial dysfunction in ALS from the novel perspective emphasizing the misregulation of dismutase activity in IMS as a major mechanism for the toxicity.In amyotrophic lateral sclerosis (ALS), mitochondrial dysfunction is recognized as one of the key elements contributing to the pathology. Mitochondria are the major source of intracellular reactive oxygen species (ROS). Increased production of ROS as well as oxidative damage of proteins and lipids have been demonstrated in many models of ALS. Moreover, these changes were also observed in tissues of ALS patients indicative of important role for oxidative stress in the disease pathology. However, the origin of oxidative stress in ALS has remained unclear. ALS linked mutant Cu/Zn-superoxide dismutase 1 (SOD1) has been shown to significantly associate with mitochondria, especially in the spinal cord. In animal models, increased recruitment of mutant SOD1 (mutSOD1) to mitochondria appears already before the disease onset, suggestive of causative role for the manifestation of pathology. Recently, substantial Amyotrophic lateral sclerosis (ALS) is a fatal paralyzing disease characterized by the selective degeneration of motor neurons in the spinal cord, brain stem and motor cortex. The majority (\u223c90%) of ALS cases are sporadic whereas some 10% of patients have dominantly inherited familial ALS (FALS). However, the forms share clinical features. The suggested causative factors for the motor neuron degeneration include oxidative stress, neuroimmune reactions, protein aggregation are products of normal oxygen metabolism in cells as superoxide and hydrogen peroxide which is a highly reactive oxidant mitochondria. Further in vivo studies revealed that mutSOD1 in spinal cords of G93A SOD1 rodents is destabilized and bound to the inner mitochondrial membrane which oxidizes it to Ot Figure . Cells lA substantial proportion of SOD1 is found in the mitochondria which all have a role in mitochondrial import and accumulation (Kawamata and Manfredi, A mitochondrial import mechanism for SOD1 independent of CCS has been described in yeast (Varabyova et al., For maturing into an active enzyme, SOD1 requires three post-translational modifications: the insertions of zinc and copper, intramolecular disulfide bond formation, and dimerization. Zinc is deposited close to the active site stabilizing the structure (Potter et al., Full activation of human SOD1 requires CCS (Wong et al., in vitro (Tiwari and Hayward, in vivo studies did not assess the localization of reduced mutSOD1, one could expect that it would be accessible to mitochondria where a part of that pool could be oxidized. In cell culture, oxidation of Cys111 residues led to accumulation of several SOD1 mutants in mitochondria (Ferri et al., In ALS, mutSOD1 is recruited to mitochondria especially in the spinal cord (Higgins et al., Furukawa and O\u2019Halloran suggestein vitro (Rodriguez et al., Most forms of mutSOD1 show instability 2O2 (He et al., The IMS-located SOD1 has been suggested to be inactive in the intact mitochondria and activated through oxidative modification of its critical thiol groups by yet poorly known mechanisms (I\u00f1arrea et al., Insertion of copper is required for the activity of SOD1 and altered copper homeostasis is a common feature in mutSOD1 mice (Tokuda et al., in vivo, suggesting that formation of heterodimers may be physiologically relevant in FALS patients as well. It has been proposed that the heterodimers comprise a pool of more soluble and more toxic SOD1 whereas homodimers form less toxic aggregates (Weichert et al., 2O2 production is not known and warrants further elucidation. In the model proposed (Figure 2O2 leads to cytC catalyzed peroxidation and mitochondrial damage.In addition to proper folding and metal acquisition, dimerization is critical for dismutase activity. Mutant and wtSOD1 are able to form either homo- or heterodimers both in animal and cell culture models (Furukawa et al., Under physiological conditions SOD activity in IMS is suppressed by redox state control. However, upon mitochondrial stress SOD1 may undergo oxidative activation and compete with cytochrome C for superoxide released in the IMS, leading to increased ROS production. In ALS, mutSOD1 accumulates in IMS, thus contributing to the misregulation of dismutase activity. The presence of endogenous wt enzyme may provide dismutase activity to inactive mutant by heterodimerization. Here we propose that aberrant regulation of dismutase activity in IMS as a major mechanism for the toxicity should be further evaluated in future studies. Furthermore, the possible involvement of mitochondrial IMS dismutase activity misregulation in sporadic ALS warrants careful assessment.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "Neisseria meningitidis serogroup X isolates from sub-Saharan Africa and Europe showed that serogroup X emergence in sub-Saharan Africa resulted from expansion of particular variants within clonal complex 181.

Additionally, we hypothesized that the composition and structure of Pinus koraiensis mixed forests would significantly be affected and Pinus koraiensis mixed forests would be overtaken by broadleaf-dominated forests in the region under the future global warming and increased precipitation.To examine the responses of composition of and structure of All necessary permits were obtained for the described field studies.

All the broadleaved trees are deciduous and most of the conifers are evergreen (except for Larix) in the study region. From June to August is the warmest quarter (summer) and January is the coldest month of the year in the study region. Rainy season begins at May or June and ends at September, and the summer (from June to August) precipitation occupies 60% of annual precipitation This study was conducted in the Augusts of 2010 and 2012 in Northeast China, including ten sites: Kuandian, Dongsheng, Liangshui, Shengshan and Changbai from A to F . The forIn each plot, every living tree higher than 1.4 m was identified to species and then measured for its circumference with a tape measure at its breast height (1.3 m). The measured circumference of each tree was converted into its diameter at breast height (DBH) and calculated into its basal area using the circle formulas.Pinus koraiensis mixed forest were extracted from each plot. The fifteen attributes were: Mean DBH of Pinus koraiensis (MeanDBHPinus), Total Basal Area of Pinus koraiensis , Stand Density of Pinus koraiensis (StandDensityPinus), Total Basal Area of Acer and Fraxinus , Stand Density of Acer and Fraxinus (StandDensityAcer-Fraxinus), Total Basal Area of Quercus , Stand Density of Quercus (StandDensityQuercus), Total Basal Area of Abies and Picea , Stand Density of Abies and Picea (StandDensityAbies-Picea), Total Basal Area of Larix , Stand Density of Larix (StandDensityLarix), Total Basal Area of Ulmus , Stand Density of Ulmus (StandDensityUlmus), Total Basal Area of Betula and Stand Density of Betula (StandDensityBetula) (Fifteen attributes of yBetula) .One-way ANOVA and correlation and regression analyses were performed using SPSS 13.0. Standard errors within sites were detected by one-way ANOVA with descriptive options. Significant differences (p<0.05) between sites were detected using One-way ANOVA with post-Duncan's test.Pinus koraiensis mixed forest. The independent factors used in the regressions were linear and quadratic components of Max Temperature of Warmest Month (TempWarmestMonth), Min Temperature of Coldest Month (TempColdestMonth), Mean Temperature of Warmest Quarter (TempWarmestQuarter), Mean Temperature of Coldest Quarter (TempColdestQuarter), Precipitation of Wettest Month (PrecipWettestMonth), Precipitation of Driest Month (PrecipDriestMonth), Precipitation of Wettest Quarter (PrecipWettestQuarter), Precipitation of Driest Quarter (PrecipDriestQuarter) and MeanDBHPinus. The 14 dependent variables were BasalAreaPinus, StandDensityPinus, BasalAreaAcer-Fraxinus, StandDensityAcer-Fraxinus, BasalAreaQuercus, StandDensityQuercus, BasalAreaAbies-Picea, StandDensityAbies-Picea, BasalAreaLarix, StandDensityLarix, BasalAreaUlmus, StandDensityUlmus, BasalAreaBetula and StandDensityBetula included in its regression model.Pinus values under current climate, under the +2\u00b0C and +10% precipitation scenario and under the +4\u00b0C and +10% precipitation scenario. In order to examine the concordances between the simulated and observed values under current climate, scatter plots with simple error bars and regressions were generated using Sigmaplot 10.0. To represent the variations of stand densities and basal areas of Pinus koraiensis, other conifers and broadleaves under current climate under the +2\u00b0C and +10% precipitation scenario and under the +4\u00b0C and +10% precipitation scenario, vertical bar charts with error bars were generated using Sigmaplot 10.0.The selected models were computed using the currently observed MeanDBHPinus koraiensis mixed forest were predicted to be zero firstly increased and then decreased with increasing latitude, while the stand density of broadleaved trees decreased with increasing latitude and altitude , while Acer and Fraxinus and Pinus koraiensis serve as late successional species during the succession of Pinus koraiensis mixed forest Pinus (which represents the stand age of a Pinus koraiensis forest) Pinus and BasalAreaAcer-Fraxinus, suggesting that Pinus koraiensis and Acer and Fraxinus are late successional species and naturally increase in their total basal areas over time. However, negative relationship existed between MeanDBHPinus and StandDensityPinus when MeanDBHPinus was below 47.6 cm Pinus koraiensis but the negative effects of summer temperatures on other conifers (Abies and/or Picea and Larix) and the positive effects of summer temperatures on some broadleaved trees (Acer and/or Fraxinus and Quercus) were observed (Pinus koraiensis trees compared with other conifer trees (Abies and/or Picea and Larix); (2) increased summer (growing-season) temperatures may enhance the growths of many broadleaved trees (Acer and/or Fraxinus and Quercus).Climate warming has positive and negative effects on plants. Prolonged growing seasons and increased growing-season temperatures have been found to enhance the growth of some plants, especially the growth of many deciduous broadleaved trees observed . Our resPinus koraiensis were observed (Pinus koraiensis populations. We suggest that the Pinus koraiensis in the region may not necessarily maintain itself under the +2\u00b0C and +10% precipitation and +4\u00b0C and +10% precipitation scenarios if proper migrations of local populations do not occur in time.A wide-ranged pine species is usually composed of many genetically-different local populations. Each local population has evolved to adapt to its local climate, and has its unique response curve to climate change observed , and thePinus koraiensis within 150 years in current Pinus koraiensis mixed forest under climate warming scenarios Pinus koraiensis could persist for at least 300 years under the warming climate Pinus koraiensis would persist, while the broadleaf trees would overtake Pinus koraiensis to become dominant species under either of the two warming scenarios (Studies using a forest gap model alone usually predicted the extinction of cenarios .Pinus koraiensis mixed forests to the climatic factors. TempWarmestMonth, TempWarmestQuarter and PrecipWettestMonth strongly affected the stand densities and total basal areas in Pinus koraiensis mixed forest and therefore they are suggested to be key climatic factors which shape the composition and structure of Pinus koraiensis mixed forest. The composition and structure of Pinus koraiensis mixed forests were significantly affected, and although Pinus koraiensis would persist, the current forests dominated by Pinus koraiensis in the region would all shift and become broadleaf-dominated forests due to the dramatic increase of broadleaf trees under the future global warming and increased precipitations.These results show that some mathematical models were successfully built to quantify the responses of the composition and structure of"} +{"text": "Magnetic Resonance Imaging of the Small Bowel is becoming increasingly popular as the first imaging modality for the diagnosis and follow-up of small bowel diseases. The aim of this work was to evaluate the role of recent MRI sequences and techniques in evaluation of small bowel disease.The study population included 24 patients who were referred to multiple radiology centers by gastroenterologist for magnetic resonance enterography (MRE) for evaluation. The examination was done on 1.5 Tesla superconducting magnet MRI.All studied patients had small bowel lesions. 15 patients were neoplastic (64%) and 9 patients were inflammatory (36%). Among 15 cases of small-bowel neoplasm; 12 were malignant; and 3 were benign. The malignant cases were classified as follows; lymphoma (6 patients); adenocarcinoma (4 patients); GIST (1 patients) and carcinoid tumour(1 patient). Nine patients out of 24 had inflammatory bowel diseases. Eight cases out of 9 proved to be specific inflammatory disease and 1 chronic non specific ileocolitis. Seven cases out of 8 proved to be Crohn\u2019s disease and 1 proved pathologically to be TB of small bowel. The final diagnosis was confirmed by surgical or endoscopic data and follow up.MRE is accurate non-invasive modalities in assessing the intra-luminal, parietal and extra-luminal small bowel tumour without the need for ionizing radiation. MR signal appearances of the lesions, combined with the contrast enhancement behavior and the characteristic of the stenosis, can help in differentiating neoplastic from other non-neoplastic diseases of small bowel."} +{"text": "The presence of joint inflammation in juvenile idiopathic arthritis (JIA) patients can be made by physical examination and confirmed by imaging. The discrepancy between physical examination and MRI for evaluation of synovitis in a target joint is possibly explained by the fact that clinical measures mostly reflect overall disease activity instead of measures specific for the joint imaged by MRI.To compare clinical disease activity of the major target joint upon physical examination with a validated MRI score for the knee in JIA.MRI datasets and corresponding clinical parameters of disease activity of the knee were analyzed in 167 JIA patients . Local physical examination of the knee included absence or presence of swelling, warmth, pain or limitation-of-motion (LOM) as assessed by experienced pediatric rheumatologists. A blinded radiologist (6 years of experience in MRI in JIA) analyzed synovial hypertrophy (SH) on a scale from 0-12 on all MRI datasets following the validated Juvenile Arthritis MRI Scoring system (JAMRIS). SH was \u2018present\u2019 when the total JAMRIS score was >2. Diagnostic accuracy of the local physical examination parameters for detection of arthritis was determined with MRI as reference standard.Sensitivity and specificity of the parameters scored by local physical examination compared with MRI varied from 39-71%. The overall positive predictive value for synovitis was very low (21-28%), while the negative predictive value was relatively good (71-74%). Median time between the clinical assessment and the MRI was 38 days (IQR 28-53 days). Subgroup analysis on 51 patients with <31 days (median 25 days) between clinical assessment and MRI did not improve the diagnostic accuracy.The presence of swelling, warmth, pain or LOM on physical examination did not predict the presence of synovitis upon MRI. The time between clinical assessment and MRI appeared to have no influence on the diagnostic accuracy of the physical examination inflammation parameters. While the discrepancy between physical examination and MRI persists, follow-up studies are warranted to unravel the difficulties in assessment of disease activity.None declared."} +{"text": "For multimodal pain therapy (MPT), a bio-psycho-social therapy approach for patients suffering from chronic pain, a core outcome set (COS) is currently lacking.

During both rounds, participants were asked to rate the importance of proposed domains regarding a) effectiveness trials (ES) and b) daily record keeping (DRK). Domains to be rated were identified through a systematic review of reported outcomes in MPT studies. During round 1, survey participants were allowed to name additionally relevant outcomes and were asked to name the number of minimal/maximal number of outcome domains to be included in the COS. During round 2 participants received feedback regarding their own previous ratings and also regarding ratings from other participants had to name which outcomes should be included in the COS.All participants completed round 1, but only 22 round 2 (88% response rate). The maximal and minimal number of outcome domains to be included in the COS ES was 9 and 4, and for the COS DRK 6 and 3. Pain intensity/severity (18/22), health-related quality of life (17/22), and pain-related disability (11/22) was named most frequently by the survey participants as being part of the COS for ES. Pain intensity (15/22), psychological distress (9/22) and both analgesic medication intake and pain-related disability (7/22) were named for the COS DRK.The results of this online survey regarding outcomes in studies evaluating MPT are mostly in line with the results from the preceding systematic review on outcome domains. Furthermore, the domains for the COS for effectiveness trials and daily record keeping were not fundamentally different. The identified preliminary outcome domains will be consented during a face-to-face meeting (consensus conference) in a moderated group discussion to determine a COS for MPT."} +{"text": "Rationale. Visual impairment is one of the most common clinical manifestations of multiple sclerosis (MS). Some multiple sclerosis patients complain of poor vision although the Snellen visual acuity is 20/20. This study reveals that sensitive measurements like visual evoked potential (VEP) and optical coherence tomography (OCT) can evidence subclinical disturbances of visual pathway. These methods examine the relation between the visual function (VEP) and retinal nerve fiber layer (RNFL) thickness, as a structural biomarker for axonal loss in patients with multiple sclerosis (MS). The findings in this study indicate the utility of combining structural and functional testing in clinical research on patients with MS.Purpose. To detect visual impairment in a population of visually asymptomatic patients affected by clinically definite multiple sclerosis (MS) and to compare the utility of optical coherence tomography (OCT) versus visual evoked potentials (VEP).Material and methods. Fourteen patients (28 eyes) affected by clinically definite MS, without a history of optic neuritis and asymptomatic for visual disturbances, were initially fully examined from an ophthalmic point of view and then measured by OCT (RNFL thickness) and VEP.Patients with a history of glaucoma or other retinal or optic nerve disease were excluded.Results. Of fourteen patients (28 eyes), VEP was abnormal in 11 cases and OCT (RNFL thickness) was abnormal in 5 cases , while 3 patients had no abnormalities on neither tests.Conclusions. Optical coherence tomography (OCT) is less sensitive than visual evoked potentials (VEPs) in detecting visual subclinical impairment in patients with multiple sclerosis (MS). VEP remains the preferred test for the detection of clinical and subclinical optic neuritis. OCT may provide complementary information to VEP in cases with clinical definite MS and represent a valuable research instrument for the study of optic nerve disease in populations. The findings in this study reveal the utility of combining structural and functional testing in clinical research on patients with MS.Abbreviations: multiple sclerosis = MS, optical coherence tomography = OCT, visual evoked potential = VEP, retinal nerve fiber layer = RNFL, best corrected visual acuity = BCVA. Just over a decade ago, MS clinical trials did not include visual outcomes, but experts recognized the need for more sensitive measures of visual function . Optical coherence tomography is used to monitor retinal ganglion cell axon loss in glaucoma, diabetic retinopathy, traumatic optic neuropathy, chiasmal lesions and optic neuritis [4-8]. Recently, OCT has been studied in patients with multiple sclerosis (MS). Two studies showed that the eyes without a history of optic neuritis among MS patients have decreased RNFL thickness compared with the eyes of control subjects, suggesting that retinal ganglion cell axonal loss occurs separately from acute optic neuritis in MS patients .Optical coherence tomography (OCT) is a noninvasive high-resolution technique that uses near-infrared light to generate cross-sectional tomographic images of tissues, including the retinal nerve fiber layer (RNFL) .This suggests that OCT can be used to monitor axonal injury and visual dysfunction in MS and may be an useful outcome measure in clinical trials [15]. In this study, we compared OCT versus VEP in the detection of visual dysfunctions in a population of visually asymptomatic patients with clinically definite MS.The alteration in visual evoked potential (VEP) latencies by using pattern stimuli is considered one of the most characteristic electrophysiological signs observed in patients with MS .The retinal nerve fiber layer (RNFL) measurements were obtained after 3 consecutive scans centered on the optic nerve head. OCT software Cirrus, Carl Zeiss Meditec generated a mean RNFL thickness measurement for 360 degrees around the optic disc, four retinal quadrants and 12 clock for our segment (30 degrees for each hour position). All scans were performed without pupil dilatation [VEPs were elicited by checkerboards reversing at 2 Hz on a television monitor located 1 m from the patient.15].VEP measurements were obtained with the patient wearing a visual aid, if needed and the fellow eye was occluded. A fixation spot was used on the center of the screen during stimulation. The latency of the first major positive peak in the VEP (P100 wave) was measured. Most investigators currently interpreted pattern reversal VEP based almost entirely on the latency of P100. A P100 latency >115ms was considered abnormal .Multiple sclerosis is a progressive disease in which subclinical RNFL thinning may occur, even in patients who have not been clinically diagnosed with optic neuritis [20]. Visual evoked potentials (VEP) remain the preferred test for the detection of clinical and subclinical optic neuritis [1].The alteration of the visual evoked potential (VEP) latencies during pattern stimulation is considered one of the most characteristic electrophysiological signs in patients with MS, visually affected or unaffected [20].The study showed that in patients affected by MS with no history of optic neuritis and no visual symptoms, there is a large prevalence of visual pathway involvement [2]. The greatest predictor for RNFL in the unaffected eye was the RNFL in the fellow affected eye [1].Clinically, it will be helpful to establish the baseline RNFL thickness and functional measurements in all MS patients at the time of the MS diagnosis. Change in RNFL thickness and/or visual function over time is likely the best approach in monitoring the disease progression [3].Based on OCT studies in MS, RNFL thickness is reduced significantly among patients (92 \u00b5m) versus controls (105 \u00b5m) and is particularly reduced in MS eyes with a history of optic neuritis (85 \u00b5m) [3].Combining information from structural and functional tests and following individuals longitudinally is probably the best strategy for assessing and monitoring the optic nerve involvement in patients with MS [4]. Imaging the RNFL allows a direct measurement of the unmyelinated axons of the central nervous system. The capacity to image central nervous system axons quickly and noninvasively, to minimize expense, and to correlate structural abnormalities with visual dysfunction add to the appeal of OCT as an imaging biomarker and outcome measure in clinical trials .The validation of OCT as an imaging biomarker in MS is important because several aspects of the information it generates are unique [The important correlation between the functional and anatomic aspect confirms the value of VEP and OCT to appreciate the subclinical involvement of the optic nerve."} +{"text": "The management of Adhesive Capsulitis(AC) is controversal. Both capsular distension after intraarticular injection and mobilization therapy are known as highly effective treatment of painful and limited shoulder joint. The aim of this study was to determine the synergistic effect of intensive mobilization technique combined with capsular distension for patients with adhesive capsulitis in improving shoulder ROM, pain and function.A total of 28 subjects suffering from AC were randomized into two groups. Group A received fluoroscopically guided capsular distension with steroid injection followed by intensive mobilization technique twice per week for 4 weeks and group B only received capsular distension with steroid injection.Patients were assessed using the Shoulder Pain and Disability Index (SPADI), Constant-Murley Shoulder Function Assessment Score (CS), Active Range of Motion(AROM) and Verbal Numeric Score(VNS). All measurements were obtained before injection and mobilization and 4 weeks after the procedures in order to compare with effects of the treatments.All measured value was significantly difference in group A and B(P<.05). Only external rotation ROM was not significantly difference in group B. The statistical differences were observed between group A and B in SPADI, CS, AROM and VNS (P<.01).Treatment using steroid injection with distension followed by intensive mobilization technique is recommended rather than injection treatment alone for the treatment of AC. In order to maximize the effectiveness of the two treatments further studies for optimal mobilization techniques will be needed."} +{"text": "Therefore, the current study demonstrated importance of mechanical factor in stem cell differentiation and showed promising protection of brain from HI injury using ELCs treatment.Neonatal hypoxic-ischemic (HI) brain injuries disrupt the integrity of neurovascular structure and lead to lifelong neurological deficit. The devastating damage can be ameliorated by preserving the endothelial network, but the source for therapeutic cells is limited. We aim to evaluate the beneficial effect of mechanical shear stress in the differentiation of endothelial lineage cells (ELCs) from adipose-derived stem cells (ASCs) and the possible intracellular signals to protect HI injury using cell-based therapy in the neonatal rats. The ASCs expressed early endothelial markers after biochemical stimulation of endothelial growth medium. The ELCs with full endothelial characteristics were accomplished after a subsequential shear stress application for 24 hours. When comparing the therapeutic potential of ASCs and ELCs, the ELCs treatment significantly reduced the infarction area and preserved neurovascular architecture in HI injured brain. The transplanted ELCs can migrate and engraft into the brain tissue, especially in vessels, where they promoted the angiogenesis. The activation of Akt by neuropilin 1 (NRP1) and vascular endothelial growth factor receptor 2 (VEGFR2) was important for ELC migration and following Hypoxic and ischemic (HI) brain injuries which result from lacking of oxygen or blood supply lead to permanent neuron damage and neurological deficit.

The cells are cultured in Boyden chamber for 6 hours, and then the cells on the lower surface of membrane will be fixed by 4% paraformaldehyde (Sigma) and stained with Giemsa to quantify the transmigrated cell numbers. To further clarify the mechanism of boosting migration ability of ELCs under hypoxic condition, the ELCs were pretreated with neuropilin-1 (NRP1) blocking peptide or inhibitor of VEGFR 1 hour before being loaded into the chamber. The migrating cell area was quantified by ImageJ software.The ability of stem cells to migrate into lesion site is important for tissue protection and regeneration.

Under regular condition (normoxia), the transmigration ability of ELCs was slightly decreased with the inhibition of NRP1 (DG2) or VEGFR (BIBF1120) signaling . The enhTo further confirm the signaling in brain tissue after receiving different therapeutic cells, the p-VEGFR2 and p-Akt were coimmunofluorescent staining with the angiogenesis marker IB4 . The appIn this study, we demonstrated the ASCs can be differentiated into endothelial lineage by synergistic stimulation of growth factor and shear stress. The therapeutic effects of both ASCs and ELCs were tested in HI injured brain. Main finding of present study supported that transplantation of ELCs showed better capacity than ASCs in preserving neurovascular structure after HI brain injury in rats. The ELCs were able to migrate and incorporate into the vascular structure in brain tissue. In addition, the ELCs can promote the angiogenesis in the impaired area as compared to ASCs. The involvement NRP1 and VEGFR2 is important for ELCs to facilitate the migration ability under hypoxic condition through Akt pathway.The angiogenic potential in early EPCs and late EPCs is comparable; there is divergence in their functions . Early EThe cell-based therapy using EPCs shows protective effect on restoring blood flow and preventing tissue damage. Upon transplantation, the EPCs home the ischemic site and incorporate into the damaged vessel structure. Studies address the fact that there are two main mechanisms for the therapeutic effect of EPCs therapy. First, the EPCs have potential to differentiate into mature ECs . After aThe crosstalk between ECs and neuron are prominent for the normal structure and function of nervous system. The ECs in central nerve system are highly specialized which connect tightly with each other and form blood barrier . The bloSeveral chemoattractants will be secreted in the injured tissue after HI insult to recruit circulating cells into the damaged area. VEGF is an important chemotactic factor for EPCs to participate in cell mobilization . VEGF acThe current study demonstrates the importance of chemical and mechanical factors in inducing the differentiation of ELCs from ASCs and the potential of using ELCs in protecting rat neonatal HI brain injury. Both ASCs and ELCs therapies can prevent the brain from HI insult by decreasing the infarction volume. Yet, ELCs showed a promising outcome in protecting the architecture and integrity of neurovascular unit. The transplantation of ELCs preserved not only the networks of vascular structure, but also the number of neurons. The mechanism for protective effect in ELCs may act through the increase of migration capacity and neovascularization after HI injury. The increase of NRP1 and VEGFR2 was identified with phosphorylation of Akt signaling in ELCs under hypoxic condition. Inhibition of NRP1 signal diminished the promotion of ELCs transmigration and Akt phosphorylation under hypoxia. Inhibition of VEGFR2 totally abolished the cell migration and endothelial differentiation in ELCs. Taken together, these results indicate that shear stress induced ELCs can be a promising cell resource for autologous cell therapy in HI brain injury."} +{"text": "To The Editor: Woodrats (Neotoma spp.) are natural hosts of Whitewater Arroyo virus (WWAV) and other Tacaribe serocomplex viruses (family Arenaviridae) in the western United States and northern Mexico . Virtually all serum samples were acute-phase specimens, and a specific diagnosis was achieved for only 55 (31.8%) of the 173 study participants.Serum samples were tested for IgG against WWAV, Amapar\u00ed virus (AMAV), an arenavirus that is antigenically closely related to the Tacaribe serocomplex viruses known to cause hemorrhagic fever of the 173 study participants. None of the 173 study participants were positive for IgG against AMAV or LCMV. The IgG titers against WWAV in the positive samples were 320 (n = 1), 1,280 (n = 3), and \u22655,120 (n = 4). WWAV was the apparent homologous virus in the 7 persons with antibody titers \u22651,280. The apparent homologous virus in the person with the titer of 320 could not be determined from ELISA data. The presence of IgG against WWAV in acute-phase serum samples implied past infection with WWAV or an arenavirus antigenically closely related to WWAV.The state of residence , sex ratio , and mean age of antibody-positive persons reflected the characteristics of the entire study population. The clinical features in each of the antibody-positive persons included fever, headache, myalgia, and thrombocytopenia. The diagnoses given for these persons were acute parvovirus infection (n = 1) by IgM assay, adult respiratory distress syndrome (n = 1) by clinical progression, and not determined (n = 6).The results of this study indicate that a small fraction of the adult population in the southwestern United States has been infected with North American Tacaribe serocomplex virus(es).

Recent demonstrations of metabolically active brown fat depots in adult humans have revolutionized current therapeutic approaches for obesity-related diseases. The balance between white adipose tissue (WAT) and BAT affects the systemic energy balance and is widely believed to be the key determinant in the development of obesity and related metabolic diseases. Members of the transforming growth factor-beta (TGF-\u03b2) superfamily play an important role in regulating overall energy homeostasis by modulation of brown adipocyte characteristics. Inactivation of TGF-\u03b2/Smad3/myostatin (Mst) signaling promotes browning of white adipocytes, increases mitochondrial biogenesis and protects mice from diet-induced obesity, suggesting the need for development of a novel class of TGF-\u03b2/Mst antagonists for the treatment of obesity and related metabolic diseases.

In this study, three ethnic groups from Bosnia and Herzegovina - Bosniacs, Bosnian Croats and Bosnian Serbs - as well as the populations of Serbians, Croatians, Macedonians from the former Yugoslav Republic of Macedonia, Montenegrins and Kosovars have been characterized for the genetic variation of 660 000 genome-wide autosomal single nucleotide polymorphisms and for haploid markers. New autosomal data of the 70 individuals together with previously published data of 20 individuals from the populations of the Western Balkan region in a context of 695 samples of global range have been analysed. Comparison of the variation data of autosomal and haploid lineages of the studied Western Balkan populations reveals a concordance of the data in both sets and the genetic uniformity of the studied populations, especially of Western South-Slavic speakers. The genetic variation of Western Balkan populations reveals the continuity between the Middle East and Europe via the Balkan region and supports the scenario that one of the major routes of ancient gene flows and admixture went through the Balkan Peninsula. It is believed that part of the Illyrians was assimilated and the other part was forced to move south - into the territory of present-day Albania th until 19th century the Peninsula was under the Ottoman control The Balkan Peninsula has been continuously settled by anatomically modern humans (AMH) since the Upper Paleolithic era Today, the Western Balkan territory is inhabDuring the last two decades the variation of uniparentally inherited markers such as mitochondrial DNA (mtDNA) and the non-recombining part of Y chromosome (NRY) have been exploited in population genetic studies in order to disentangle the problems of the diversity and dispersal of humans both in global and local contexts The study of the variation of mtDNA in the population of Bosnia and Herzegovina has shown - like in case of the variation of NRY - that the majority of detected mtDNA hgs among Bosnians belong to the common West Eurasian gene pool The aim of this study was to characterize, in a larger geographical context, the autosomal gene pool of eight Western Balkan populations from six countries - Bosnia and Herzegovina, Croatia, Serbia, former Yugoslav Republic of Macedonia, Montenegro and Kosovo. All studied samples were characterized also for mtDNA and NRY diversity. One of the main questions we address here is whether the whole genome approach with the accent on the variation of autosomal SNPs is in concordance with the information about genetic affinities of the populations of Western Balkan region, revealed by the studies of uniparental markers.Genome-wide autosomal markers of 70 Western Balkan individuals from Bosnia and Herzegovina, Serbia, Montenegro, Kosovo and former Yugoslav Republic of Macedonia .

The fIBD algorithm was applied to the 22 autosomes in 10 iterations and the IBD threshold was set to 1e\u201310. Since the power of the fIBD algorithm to detect segments shorter than 1 centiMorgan (cM) is low, we considered only ibd segments longer than 1cM. We summarized ibd sharing for six classes of ibd segments . We estimated an average number of ibd segments per pair of individuals for Muslim and non-Muslim populations of Western Balkan vs Middle Eastern populations algorithm implemented in BEAGLE software package and non-Muslim of the Western Balkan populations share around 1.5 ibd segments per pair with the population from the Middle East patterns of ibd sharing with Middle Eastern populations for shorter classes of ibd segments .

The variation analysis of 660K autosomal SNPs of 70 individuals from Western Balkan populations revealed that the genetic uniformity that has been shown by studies of uniparentally inherited markers of these populations can be seen also at the whole-genome level. Thus, culturally diverse Western Balkan populations are genetically very similar to each other. These results, together with the high-resolution analysis of the variation of mtDNA and NRY, let us to affirm that the genetic profiles of Western Balkan populations resemble that of their closest geographical neighbors, and in the global context are in concordance with the geographical distribution of the studied population.The major variants of the gene pool of present-day Western Balkan populations have developed from a common source without being influenced by major population-specific bottlenecks. In a more general perspective, our results reflect clear genetic continuity between the Middle Eastern and European populations.

Further, white spots (early stage of caries) completely disappeared in 80% cases after 15 applications of the dentifrice. Thus, it appears that 15 procedures of remineralizing therapy with ROCS Medical Minerals are enough for mineralizing of white hypoplastic spots. Most patients with hypersensitivity (82% and 93% in two groups) noticed significant reduction of painful reactions after two 15-minutes applications.

Pulmonary artery pressure waveform analysis provides information about phenomena that affect RV performance. In particular, pulmonary vascular wave reflection (WR) is directly related with RV stress. We hypothesised that open lung ventilation (OLV), compared with conventional ARDS-net ventilation (CV), would improve conditions for RV performance in an ARDS model. This hypothesis was tested by measuring pulmonary vascular wave reflection (WR).To evaluate the effect of two mechanical ventilation (MV) strategies on WR in an experimental model of ARDS.8 anesthetized and muscle relaxed pigs were submitted to a two-hit lung injury model combining repeated lung lavages with injurious MV. After lung injury was induced, animals were randomized (4 pigs in each group) to one of two strategies of MV: OLV, PEEP 2cmH2O above the PEEP corresponding with the maximal dynamic compliance in a decreasing PEEP trial after a recruitment manoeuvre; or CV, PEEP adjusted according to the ARDSnetwork table. In both groups tidal volume was 6ml/kg, respiratory rate to maintain PaCO2 between 55-65 mmHg and FIO2 to maintain PaO2 55-80 mmHg.1 and quantify WR.

These signals were used to separate the forward and backward components of the pressure waveformWe did not find any significant changes by induction of ARDS but both APbw and RI were lower in OLV comparing with CV.In this experimental ARDS-model OLV decreased WR in the pulmonary vascular system comparing with CV, indicated that OLV could reduce the stress on the RV and improve conditions for RV performance."} +{"text": "Traumatic injury of the central nervous system (CNS) has severe impact on the patients\u2019 quality of life and initiates many molecular and cellular changes at the site of insult. Traumatic CNS injury results in direct damage of the axons of CNS neurons, loss of myelin sheaths, destruction of the surrounding vascular architecture and initiation of an immune response. Class III semaphorins (SEMA3s) are present in the neural scar and influence a wide range of molecules and cell types in and surrounding the injured tissue. SEMA3s and their receptors, neuropilins (NRPs) and plexins (PLXNs) were initially studied because of their involvement in repulsive axon guidance. To date, SEMA3 signaling is recognized to be of crucial importance for re-vascularization, the immune response and remyelination. The purpose of this review is to summarize and discuss how SEMA3s modulate these processes that are all crucial components of the tissue response to injury. Most of the functions for SEMA3s are achieved through their binding partners NRPs, which are also co-receptors for a variety of other molecules implicated in the above processes. The most notable ligands are members of the vascular endothelial growth factor (VEGF) family and the transforming growth factor family. Therefore, a second aim is to highlight the overlapping or competing signaling pathways that are mediated through NRPs in the same processes. In conclusion, we show that the role of SEMA3s goes beyond inhibiting axonal regeneration, since they are also critical modulators of re-vascularization, the immune response and re-myelination. Class III semaphorins (SEMA3s), apart from their classical axon repulsive properties, exert regulatory functions in a variety of non-neuronal cells associated with CNS trauma.Neuropilins (NRPs) are pleiotropic receptors involved in multiple signaling pathways controlling tissue remodeling following CNS trauma.Semaphorin signaling is regulated at several levels, including receptor complex formation, proteolytic cleavage and interaction with extracellular matrix molecules.Interfering with class III semaphorin signaling might be beneficial for axonal re-growth, re-vascularization, re-myelination and manipulation of the immune response following CNS trauma.The semaphorin family consists of secreted and transmembrane glycoproteins that are involved in many cellular functions. Semaphorins (SEMAs) are subdivided into eight classes based on amino acid sequence similarities and structural features. The first two classes of SEMAs are found in invertebrates, class III till VII belong to vertebrates, while class VIII semaphorins are only expressed by viruses injuries due to their presence in neural scar tissue. The expression of SEMA3s following CNS trauma is suggested to be important in both the acute and sub-acute/chronic phases of scar formation. To date there is data showing Sema3A mRNA up-regulation as early as 1 day after CNS penetrating lesions and a small CSPG called Decorin. ChABC digests the chondroitin sulphate (CS)\u2014 glycosaminoglycan (GAG) chains of CSPGs, while decorin suppresses multiple repulsive proteoglycans in the extracellular matrix. Among the repulsive molecules that could be affected from treatment with the above approaches is SEMA3A which in earlier in vitro, but was unable to enhance axonal regeneration and functional recovery after SCI in vivo from Sema3A-induced apoptosis after optic nerve axotomy enhances axonal regeneration in an in vitro model of cerebral ischemia. VEGF rescued cultured CNS neurons from hypoxia and glucose deprivation induced apoptosis and receptor complexes consisting of NRPs and VEGFRs , there is degeneration of the vascular architecture and the hypoxic regions display dysregulated hyper revascularization. Interestingly, the newly formed blood vessels are not capable to reach the neural retina. The inflammatory and ischemic stress induced expression of Sema3A by RGCs prevented revascularization of the eye since RGC-derived Sema3A repelled blood vessels and inhibited EC growth , which in turn, inactivates integrin receptors. Secondly, Sema3E induces the activation of ADP-ribosylation factor 6 (Arf6) positive vesicles that promote internalization of integrin receptors. In contrast to these functions of SEMA3s as inhibitors of angiogenesis and integrin functions, Sema3C promotes angiogenesis in vitro by activation of integrins and their receptors are key modulators of the immune response secrete cytokines that can be toxic for CNS neurons, while the non-classical anti-inflammatory type 2 macrophages (M2) can promote neuroregeneration across neuronal repulsive substrates signaling, which is NRP1-independent, exerting anti-proliferative and immunosuppressive effects that induce fibrosis and non-canonical signaling pathway which is NRP1-dependent and can antagonize canonical signaling As mentioned earlier in this review blockage of SEMA3s signaling might favor revascularization and thus the innate ability of the organism for effective clearance and recycling of the excessive inflammatory cells through the circulatory pathway; and (2) NRP1 receptors of inflammatory cells may become available for TGF-\u03b2 signaling, which suppress the immune response perhaps more sufficiently than SEMA3s. Therefore, the role of SEMA3s in modulating the immune response after traumatic CNS injury needs to be investigated in more detail.Trauma of the CNS induces mechanical forces that cause loss of OLs and demyelination of axons at and surrounding the injury site. The loss of myelin sheaths decreases the conduction velocity of action potentials and could result in axonal degeneration. The reestablishment of myelin sheets around demyelinated axons and around newly sparsely formed regenerating axons, a process called remyelination, is therefore important to regain neuronal function after brain and spinal cord injuries axonal regeneration; (2) re-vascularization; (3) immune response; and (4) re-myelination (Figure axonal rIn the sub-chronic and chronic phase of CNS injury SEMA3s may inhibit axonal regeneration by inducing apoptosis of neurons and by preventing axons to penetrate scar tissue. They may also restrict re-vascularization by SEMA3B inhibition of the recruitment of pericytes that normally stabilize new blood vessels and by SEMA3A mediated elevation of the vascular permeability of blood vessels even when the expression of VEGFA declines. This increased vascular permeability may have a direct impact on the chronic immune response where SEMA3s are shown to inhibit the proliferation of recruited T-lymphocytes and antagonize the synthesis of cytokines such as IL-2, IL-4, IL-10 and IFN\u03b3. Furthermore SEMA3A induces apoptosis of microglia that express NRP1 and thereby influence the survival and axonal regeneration capacity of injured CNS neurons. Additionally SEMA3A induces cell death of M2 macrophages and could thereby induce a \u201cpro-inflammatory\u201d M1 macrophage environment in the scar. An intriguing but yet not fully established hypothesis is that SEMA3s might modulate TGF-\u03b2 non-canonical signaling via NRPs at inflammatory cells near the scar tissue. Finally, re-myelination is also affected by SEMA3s at the chronic stages of injury. In particular SEMA3A inhibits the recruitment and differentiation of OPCs and inhibits the mobility of migrating Schwann cells. In contrast, SEMA3F promotes OPC migration and remyelination. Lastly, SEMA3A signaling via NRP1 might antagonize furin-processed SEMA3F, EGF and PDGF signaling pathways that all posses the ability to stimulate remyelination.Since the discovery of Sema3A in 1993, SEMA3s signaling and their receptors were increasingly recognized to be involved in key processes influencing axonal outgrowth and guidance. However, substantial evidence indicates that SEMA3s also participate in cell-to-cell communication systems that underlie angiogenesis, inflammation and re-myelination. It will be necessary to combine the knowledge obtained from the research fields of vascular biology, cancer biology, immunology and glial biology in order to better understand the role of SEMA3s signaling in CNS trauma. A combinatorial approach involving these fields of research may be necessary in order to move closer towards a therapy for traumatic CNS injury. SEMA3s are an important target in strategies that aim to repair traumatic spinal cord and brain injuries, however the sometimes overlooked pleiotropic nature of their NRP receptors needs to be addressed/understood in a more thorough fashion in future studies.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "Growing demand of resources increases pressure on ecosystem services (ES) and biodiversity. Monetary valuation of ES is frequently seen as a decision-support tool by providing explicit values for unconsidered, non-market goods and services. Here we present global value transfer functions by using a meta-analytic framework for the synthesis of 194 case studies capturing 839 monetary values of ES. For 12 ES the variance of monetary values could be explained with a subset of 93 study- and site-specific variables by utilizing boosted regression trees. This provides the first global quantification of uncertainties and transferability of monetary valuations. Models explain from 18% (water provision) to 44% (food provision) of variance and provide statistically reliable extrapolations for 70% (water provision) to 91% (food provision) of the terrestrial earth surface. Although the application of different valuation methods is a source of uncertainty, we found evidence that assuming homogeneity of ecosystems is a major error in value transfer function models. Food provision is positively correlated with better life domains and variables indicating positive conditions for human well-being. Water provision and recreation service show that weak ownerships affect valuation of other common goods negatively (e.g. non-privately owned forests). Furthermore, we found support for the shifting baseline hypothesis in valuing climate regulation. Ecological conditions and societal vulnerability determine valuation of extreme event prevention. Valuation of habitat services is negatively correlated with indicators characterizing less favorable areas.

Due to the variation in site characteristics, e.g. socio-economic or biophysical feature , 31, andWith this publication we i) provide a conceptual base supporting the establishment of a standardized integration and reporting on uncertainties of benefit transfer. Building on this we ii) assess the transferability of monetary values of ES and identify major sources of uncertainty by using meta-analytical value transfer functions.We generated a spatially explicit database of 194 globally distributed cases studies covering 839 monetary values of ES from peer reviewed data collections , 36.

A BRT computes the relative influences (importance) of covariates for a BRT model, i.e. they identify major determinants of the variance in monetary values of ES. BRT also provide elasticity curves that account for non-constant marginal value changes over distinct socio-ecological conditions and thus quantify the change of monetary values in response to an alteration in one covariate (i.e. ceteris paribus) ; see S2 We tested different parameter of the BRT algorithm such as learning rate, tree complexity, minimal number of observations in terminal nodes and number of trees see , and choStatistical significant value transfer functions could be computed for 12 ES types based on 839 monetary values . Most important covariates were quantified and monetary values in unsampled areas extrapolated . If therIn an additional step confidence intervals were estimated to examine generalization failure of value transfer functions from training data . We reruFor the discussion of the results we conceptualized three major sources of uncertainty of value transfer functions: (i) Sample error, such as measurement error in input studies for value transfer functions or publication selection bias; (ii) errors originating from statistical estimation of BRT models (model performance and suitability of chosen approach for benefit transfer); and (iii) transfer error from generalization that encompasses distortions due to value transfer without fully accounting for site and study characteristics. Only covariates with >1% were analyzed for the six groups of covariates. Additionally, in a fourth point we provide information of the spatial application of the value transfer functions.All studies considered in the synthesized database come froThe final 12 cross-validated value transfer functions explain from 18% (water provision) to 44% (food provision) of the variance of monetary values . FurtherResults from the quantification of the importance of covariates for the value transfer functions indicate which site and study characteristics need to be considered in order to minimize transfer error from generalization. In The application of the value transfer function for spatial extrapolation of values in unsampled areas results in a map shown in In the following section we discussed the results in detail for 6 out of 12 ES. Food and water provision, climate and extreme events regulation as well as recreation and habitat service were selected, because they represent the highest variance of monetary values from each ES group , see Available input data: With 158 monetary values the largest data set is available for food provision. The majority of case studies examine fish provision (51%) in lower latitudes (93%) and in coastal ecosystems or inland wetlands (69%). Lower latitudes are most likely food-insecure regions with a high vulnerability to climate change . CoastalModel uncertainty: The value transfer function shows the lowest uncertainty and explains 44% of the variance in the data. Estimations of the confidence intervals show that for 91% of the terrestrial earth surface monetary values can be computed with low and medium uncertainty (1 to 80 Int.-$-2007 per ha), due to a high number of data points .Importance of covariates: Most important covariates are climate indicators (22%), followed by geographic and nature endowment (15%) and valuation methods (15%). Further influential are social covariates such as better life domains of human well-being (12%) and religion (3%) as well as the economic covariate agricultural subsidies (3%).2 per grid cell). Variance explained by distance to sea (9%) is a logical consequence from the distribution of studies and the focus on fish as food resource. In more landlocked areas the importance of fish in the food supply reduces and so does the monetary valuation of fish. Moreover, the type of biome explains 6% of the variance, but does only partly coincide with the land use classification used on the case studies itself. These show that coastal wetlands, coastal systems and cultivated areas (aquaculture) are most valued, and confirm previous findings from [Ecology: Covariates indicating climate and those on geographic and nature endowment show low values in areas with prevailing unfavourable growing conditions and low human-induced alteration of ecosystems <11%) or high amounts of alternative food products , followed by benefit transfer (17%) and group valuation (5%). With group valuation significant lower values are derived. Most studies (75%) based on group valuation were conducted for fish in India, a country where fish consumption represents only 2% of protein intake , which mSociety: The valuation of food increases with a lower unemployment rates (<10% of labour force) and a high number of people in working age (15\u201359 years), good education system as well as with improving sustainable well-being measured by years of life satisfaction achieved per unit of resource used (Happy Planet Index). These covariates directly relate to the better life domains of the Organisation for Economic Co-operation and Development (OECD), which are essential metrics for human well-being . This shEconomy: With increasing subsidies in agricultural sector the value for food provision decreases. Subsidies distort markets by promoting the production of agricultural commodities beyond market demand, thus, they encourage farmers and fishermen to rely on them instead of consumer wants .Application of value transfer function: Spatial extrapolation of values shows for food the highest uncertainties and lowest values are in India and parts of Africa . On contAvailable input data: For water provision one of the smallest datasets was available (26 case studies). Most of the case studies were conducted in climate sensitive lower latitudes (63%). Climate change is affecting the hydrologic cycle and directly impacts the water resource base, usage, and management, in particular in lower latitudes .Model uncertainty: The value transfer function for water provision shows the highest uncertainties and explains 18% of the variance . ConfideImportance of covariates: Most influential are ecosystem-based covariates that indicate biodiversity and water availability (67%), followed by type of biome (3%). Further important are covariates of social and economic indicators (22%).2 per grid cell), in particular, agricultural frontier areas of cropland foster high values for water provisioning . Third, deforestation explains 3% of the variance and is positively correlated with water values. Water availability, moreover, depends on the spatial (3%) and temporal allocation of water resources (2%). The more unequal rivers and lakes are distributed in an area the higher is the value for water provision. Seasonal variability or long-term climatic changes cause extended periods of droughts or water abundance. The type of biome explains 3% of the variance. However, the applied land use classification system differs from the actual biome type of the case studies. Taking case study based classification into account coastal wetlands and freshwater (rivers/lakes) show highest values, confirming [Ecology and society: Areas of high biodiversity threat and conservation value are positively correlated with monetary values and explain 21% of the variance. Biodiversity and water supply are strongly interrelated , 53. Drinfirming , 28, 29.Economy: The portion of privately owned forests is positively correlated with water provision value (5%). This confirms that weak ownerships might affect valuation of other common goods negatively . SimilarApplication of value transfer function: Spatial extrapolation of values shows the most certain and highest values in areas of high population growth and increasing pressures on water security, for instance in China, India, Java, eastern USA, south Mexico and Western Central America, south coast of Western Africa, and Mediterranean Europe . TransfeAvailable input data: From a total of 36 case studies , carbon sequestration was most frequently examined (68%), followed by other greenhouse gases (<2%) or remain unspecified (24%). The majority of studies were carried out in tropical and temperate forests (25%) as well as inland and coastal wetlands (45%). These biomes are seen as regions highly suitable for carbon sequestration , 59. MorModel uncertainty: With 38% of variance explained in monetary values the transfer model for climate regulation represents the third best prediction performance . For mosImportance of covariates: The most important covariates are ecosystem-based variables of nature threats (49%). Also relevant but explaining less of the variance are covariates indicating input measures of climate sensitive economic sectors (20%) and other economic variables (6%), followed by scale (7%), methods (6%) and social variables (4%),3) exist. Furthermore, the economic covariate inequality of income (6%) shows that the more unequal income is distributed the higher the value for climate regulation.Ecology and economy: Covariates of nature threats show that high values are associated with areas of high risk that unique biodiversity will soon be lost (30%) and high risk of erosion (19%). Covariates indicating input measures of climate sensitive economic sectors (e.g. energy production and water business) are positively correlated with monetary values for climate regulation. Most important covariates are: proportion of electricity production from hydroelectric sources (12%), annual mean of solar radiation (6%) and the water storage capacity of dams per country (2%). Values are high, for instance, in areas of lower latitudes where up to 99% of electricity is produced by hydroelectric power plants and where big artificial constructed water reservoirs , followed by direct market prices (16%) and avoided costs (11%). For direct market prices the highest values and for benefit transfer and replacement costs the lowest ones can be observed.Society: Social covariates of relevance are population density per country (2%) or the age of population (2%). Population density is negative correlated with monetary values. Surprisingly, case studies in countries with on average older population report higher values of climate regulation. One might hypothesize older people may have made in their lifetime perceiving changes in climatic conditions and associated consequences, thus, valuing climate regulation service higher than younger persons. This might be an indication for the \u201cshifting-baseline\u201d hypothesis, i.e. shifts of the reference points of human perception for estimating changes .Application of value transfer function: Applying the value transfer function shows that the most certain and highest values are computed for areas under threat of habitat alteration due to climate change or other land degradation processes. Examples are areas like the Sahel Zone, tropical islands and mountains, Mediterranean ecosystems, Eastern USA and parts of Europe . On contAvailable input data: The majority of case studies (82%) were conducted in areas of high vulnerability to extreme events and sites which are increasingly exposed to extreme events due to climate change \u201363. In 4Model uncertainty: The value transfer function for prevention of extreme events represents medium prediction performance and explains 21% of the variance in monetary values . TransfeImportance of covariates: The impact of extreme events depends on both ecological conditions and societal vulnerability. We found that with 64% the highest explanatory power is represented by covariates showing the inherent conditions of ecosystems, followed by socio-economic characteristics (33%) and covariates dealing with the spatial and temporal scale (3%).Anthropogenic pressure on the ecosystem: Extreme event prevention is valued high in areas with advanced anthropogenic alteration of ecosystems characterized by highly changed biomass (HANPP 13%), high agricultural induced soil erosion rates (10%), degraded freshwater resources and riverine biodiversity (10%), dense infrastructure (5% market access), dense settlements with major markets (4% Anthromes) and high population density (3%). Hence, the risk awareness to weather extremes and natural hazards increases with number of people potentially effected and higher level of land-use and degradation. The more risk aware a society is, the more weight it places on strategies that preserve or build ecosystem resilience, and the higher the value it would allocate to ecosystem configurations that are more robust . This isSpecies richness and unemployment: We also found that areas with high species richness (4%) and high level of conservation priority (3%) show high valuation for extreme event prevention. These areas are characterized by high population, the highest population growth rates globally , 56 and Application of the benefit transfer function: Using the value transfer model for spatial estimations of extreme event prevention show that the most certain and highest valuations are situated in densely populated areas with advanced anthropogenic altered environments . The larAvailable input data: The database for the ES recreation services captures with 96 the most case studies. The majority of studies were conducted in major non-religious and Christian sites (73%) as well as lower latitudes (77%). Studies in developing countries < 4024 US-$) are underrepresented (26%). Subcategories of recreation services investigated are tourism (41%), hunting (<1%), ecotourism (<1%) and unspecific recreation (47%).Model uncertainty: The value transfer function for recreation services is with 33% variance explained the fourth most certain model . ConfideImportance of covariates: With 32% ecosystem-based covariates are the most influential group. In comparison with other value transfer functions, however, this is the lowest value . Further2 and a soil moisture index of 1 to 1.6. This corresponds to areas in the (sub-) tropics, see Ecology: More homogeneous environments receive lower values for recreation. The value transfer function shows that areas are low valued with intensive agricultural use (6%), a high number of people living on degraded land (2%) and low number of terrestrial protection areas (4%) and biodiversity (2%) as well as low ethnic diversity (1%). Surprisingly there is a negative effect of marine protection areas (4%) and length of coastlines (1%). This is due to the low number of case studies carried out in coastal areas (17%) and marine protection areas (16%). Furthermore, covariates on land use/land cover types explain 9% of the variance and show that wetlands and freshwater areas (river/lakes) are highest valued. The most important climatic covariates are solar radiation (3%) and soil moisture (2%). The latter one is strongly correlated with precipitation. Highest monetary values are shown for areas with 100 to 190 W/mEconomy and society: Economic covariates show that recreation is highly valued in wealthy countries. These countries are characterized by high market access (3%), low GDP growth (3%), low consumer prices (2%), positive trade balance and a high level of export to import ratio (3%). In wealthy countries the access to a greater share of ES and substitutes is provided, thus, the basis for recreation given. However, in areas with a high unemployment rate (6%) recreation values are high, too. We hypothesize these are sites where tourism is already established and an important economic factor. With increasing portion of privately owned forests the value for recreation is higher (1%). This shows that with the granting of property rights the valuation of common goods might be positively affected and emphApplication of value transfer function: Applying the value transfer function shows that the most certain and highest values are in the USA, most of the Mediterranean area, Caribbean islands, and Colombia . These aAvailable input data: The database for habitat service contains one of the smallest numbers of case studies .Importance of covariates: The group of ecosystem-based covariates contributes with 90% to the value transfer function . These aEcology and society: Habitat services are valued less in marginal areas, i.e. harsh growing conditions due to low soil quality (24%), arid climate zones with high drought potential (16%) and high UV exposure (26%). Marginal areas are mostly sparsely populated (1%) and characterized by low market access (3%). Also those areas are the home of poor people , 73 withApplication of value transfer functions: Spatial extrapolation shows the most certain values in low valued marginal areas like the highlands and drylands of Asia and sub-Saharan Africa, transition zones of the grassland to deserts of Australia as well as southern Latin Americas Andes Mountains, and the highlands and drylands of North America .Although \u201cmoney\u201d is seen as a well-known and easily understandable indicator, monetary valuation of ES is ambiguous and shows only a fraction of the multiple characteristics that give utility to the beneficiary . ApplyinThe data availability and the quality of input studies determine the sampling error. We only included valuation studies that were reviewed by experts as a minimal assurance of study quality. Although the peer review approach is often criticized it is also appreciated as an efficient method that increased the scientific progress over the past decades . The majAnother concern with respect to the input data refers to the aggregation of the monetary values. In order to create a comparable data base for spatially explicit value transfer modelling, monetary values need to be disentangled. Only values measured under marginal changes in the socio-ecological system were considered . We utilUtilizing BRT for spatially explicit, meta-analytic value transfer functions have inherent causes of error, too. Although this method is acclaimed to be one of the most sophisticated approaches for benefit transfer , 82 the The spatial application of the value transfer functions in unsampled areas generates transfer errors from generalization, which are determined by uniformity, spatial extent and resolution as well as temporal aspects , 83. We Regionalization error encompasses extrapolation errors due to generalization from a local case study to a wider region . All valThe major achievement of this study is, first, to clearly distinguish between major sources of uncertainties and to quantify patterns in the influence of different study- and site-characteristics that affect value transfer functions and predicted ES values. Second, the study identifies regions for which sufficient knowledge on our natural capital is available, i.e. a statistically defensible benefit transfer model can be applied in combination with uncertainty values. Third, we provide global maps of the \u201cwhite spots\u201d on our knowledge on accounting natural capital and ES.

During their maturation process, these immature neurons exhibit unique properties that could underlie their ability to influence behavioral output. In particular, abGCs in the DG exhibit a period of heightened plasticity 4\u20136 weeks after birth that is mediated by GluN2B-expressing NMDA receptors. The functional contribution of this critical window to AD responsiveness is unclear. Here, we determined the behavioral and neurogenic responses to the AD fluoxetine (FLX) in mice lacking GluN2B-containing NMDA receptors in abGCs. We found that these mice exhibited an attenuated response to FLX in a neurogenesis-dependent behavioral assay of FLX action, while neurogenesis-independent behaviors were unaffected by GluN2B deletion. In addition, deletion of GluN2B attenuated FLX-induced increases in dendritic complexity of abGCs suggesting that the blunted behavioral efficacy of FLX may be caused by impaired differentiation of young abGCs.

We have utilized clinical specimens and cell lines to examine the regulation, functional role, and clinical significance of the PI3K-AKT pathway in melanoma.All analyses of clinical specimens were performed under protocols approved by the MD Anderson Institutional Review Board. Identities of cell lines were confirmed by STR-fingerprinting, and cell lines were genotyped by sequenom analysis for hotspot mutations. Reverse phase protein array (RPPA) analysis was performed by the MD Anderson RPPA Core Facility.Proteomic analysis of frozen melanoma clinical specimens and cell lines demonstrated that phosphorylation (activation) of AKT (P-AKT) correlated inversely with PTEN protein expression. Confirmatory analysis of PTEN expression by an immunohistochemical (IHC) assay on archival tumor samples identified a linear correlation between PTEN measurement by IHC and RPPA. Significantly increased expression of P-AKT was observed in melanomas with complete loss of PTEN protein expression compared to tumors with any other pattern of PTEN expression. Integrated analysis of BRAF/NRAS mutation status, PTEN expression, and clinical outcomes was performed using lymphadenectomy specimens from patients who underwent surgery for stage IIIB/C melanoma. Complete loss of PTEN expression correlated with shorter overall survival and time to brain metastasis on univariate and multivariate analyses. Testing of human melanoma cell lines demonstrated that cells with baseline or compensatory activation of the PI3K-AKT pathway were generally resistant to apoptosis induction following BRAF or MEK inhibition. Extended molecular profiling found that a subset of melanoma cell lines with de novo and acquired resistance to MEK inhibitors are characterized by increased expression of PGC1alpha and a metabolic phenotype of high oxidative phosphorylation (OxPhos). The resistant high OxPhos cell lines all demonstrated synergistic growth inhibition and apoptosis induction with combined targeting of MEK and mTORC1/2. mTORC1/2 inhibition decreased PGC1alpha expression in vitro and in vivo, and caused cytosolic localization of MITF. Treatment with a MEK inhibitor and an mTORC1/2 inhibitor demonstrated marked synergy in a BRAF-mutant, MEK inhibitor resistant human melanoma cell line in vivo.Activation of the PI3K-AKT pathway correlates with clinical outcomes and resistance to MAPK pathway inhibitors in melanoma. These findings support the rationale to determine the clinical benefit of inhibiting the PI3K-AKT pathway in this disease."} +{"text": "We hypothesize that changes of shape of arterial blood pressure (ABP) high-frequency waveform signal can be reflective of body's response to stress, in particular to hemorrhage.To apply Machine Learning (ML) and sequential pattern extraction to ABP waveforms to reliably detect slow bleeding.62 healthy pigs are anesthetized, intubated, ventilated, and instrumented prior to and during a controlled bleeding at a rate of 20 ml/min.

Upon using logistic regression models we analyzed the relationship between the probability of occurrence of five macroinvertebrate families, ranging from pollution tolerant to pollution sensitive, and physical-chemical water quality conditions. Within the investigated physical-chemical ranges, nine out of twenty-five interaction effects were significant. Our analyses suggested river basin dependent associations between the macroinvertebrate families and the corresponding physical-chemical conditions. It was found that pollution tolerant families showed no clear abiotic preference and occurred at most sampling locations, i.e. Chironomidae were present in 91%, 84% and 93% of the samples taken in Ecuador, Ethiopia and Vietnam. Pollution sensitive families were strongly associated with dissolved oxygen and stream velocity, e.g. Leptophlebiidae were only present in 48%, 2% and 18% of the samples in Ecuador, Ethiopia and Vietnam. Despite some limitations in the study design, we concluded that associations between macroinvertebrates and abiotic conditions can be river basin-specific and hence are not automatically transferable across river basins in the tropics.

The first series of boxplots visualized the seasonality of the physical-chemical variables per river basin. The second series of boxplots summarized for each macroinvertebrate family and per physical-chemical variable and river basin the conditions under which the taxon was present and absent. Boxplots were constructed with the R software The univariate associations between explanatory variables were assessed with pairwise Spearman's rank correlations, which is often used in ecology due to its nonparametric nature The occurrence of five macroinvertebrate families was related to the physical-chemical water quality conditions using a regression-based model and these relationships were compared between three river basins situated in the tropics. Logistic regression models (LRMs) were used to infer relationships between occurrences of five aquatic macroinvertebrate families and environmental data. LRMs have been frequently used to model the presence or absence of a species in relation to environmental variables A hierarchical backward elimination model selection method was carried out to build the LRM. The starting model included five physical-chemical variables , season and river basin (represented as country). In addition to the main effects, two-way interactions between the physical-chemical variables and the river basin as well as between season and river basin were included and S2. Residual plots and the extended Hosmer-Lemeshow test for LRMs based on GEE The outcome of the LRM per family was visualized as the estimated probability that the family was present as a function of a physical-chemical variable. The explanatory variables different from the one on the x-axis, were set to their river basin specific medians and the season to \u201cdry\u201d. The river basin-specific observed range of the corresponding physical-chemical variable were plotted as horizontal boxplots below the response curves and were subdivided between presence and absence points. The gray-colored ends of the response curves indicate extrapolation outside the observed range of the corresponding physical-chemical variable.For the data exploration, the effects of season and river basin on the continuous physical-chemical variables were assessed using a linear regression model fitted with GEE for accounting for the clustered sampling scheme. Only few p-values were reported in the main text to prevent information overload, all p-values were summarized in The observed range of physical-chemical water quality conditions was not always equal between river basins. Seasonal effects were observed for all physical-chemical variables and the seasonal effect of conductivity and stream velocity was similar for the three river basins \u2013S8. DissThe prevalence values, known as the relative frequencies of occurrence of taxa , i.e. the effect of water temperature on the occurrence differed between river basins . AlthougThe effect of water temperature on the probability of occurrence of Baetidae differed between river basins p<0.01; . Indeed,Associations between the DO concentration, pH, stream velocity and water temperature relative to the probability of occurrence of Hydroptilidae were similar across river basins . Only thThe associations between water temperature (p<0.01), stream velocity (p\u200a=\u200a0.02) and DO concentration (p\u200a=\u200a0.02) and the probability of occurrence of Libellulidae differed between river basins . WhereasAssociations between stream velocity and S54,\u22121 for optimal health For pollution tolerant macroinvertebrate families (e.g. Chironomidae (TS2)) only few significant associations between physical-chemical conditions and the occurrence of the families were found suggestiHabitat suitability of macro-invertebrates probably depends on more factors than those included in our statistical analysis. For instance, additional to the variables that were included in our analysis, Al-Shami et al. Seasonal changes of environmental variables were taken into account The outcome of the LRM per family was visualized as the estimated probability that the family was present as a function of a physical-chemical variable e.g. \u20135. WithiThe fact that river basin dependent associations were found is not surprising. For instance, Bonada et al. Since the range of the observed physical-chemical conditions were not always equal between river basins, in some cases extrapolations outside the observed range were shown . For insNo relation was found between the occurrence of Leptophlebiidae and stream velocity in the Ethiopian and the Vietnamese river basin. However, according to the data Leptophlebiidae occurred in both river basins in upstream sampling sites with a moderate to high stream velocity. The reason for the non-significant relation is the prevalence of the present-points. In the Vietnamese and Ethiopian river basin, Leptophlebiidae were only present in 18% and 2% of the samples, respectively. Consequently, the occurrence of Leptophlebiidae seems statistically not associated with stream velocity. Therefore, due to unbalanced dataset prevalence it is possible that not all models obtained represent true ecological relations Presence and absence data are commonly used in macroinvertebrate research e.g., as they As an alternative to the conventional taxonomic division of the benthic invertebrates one can use functional traits to categorize macroinvertebrate assemblages e.g., . Such a Overall, LRMs based on GEE are a flexible way to model the probability of occurrence of macroinvertebrates as a function of environmental variables. We revealed similar as well as dissimilar abiotic preferences of macroinvertebrates between the three river basins, but these estimated probabilities are restricted to the observed range of the predictor within each river basin. In conclusion we found that associations between macroinvertebrates and abiotic conditions can be river basin-specific.Figure S1Sampling sites in the Chaguana river basin in Ecuador.(DOCX)Click here for additional data file.Figure S2Sampling sites in the Gilgel Gibe river basin in Ethiopia.(DOCX)Click here for additional data file.Figure S3Sampling sites in the Cau river basin in Vietnam.(DOCX)Click here for additional data file.Figure S4Boxplots showing the seasonality (dry (blue) and wet (red) season) of the stream velocity.(DOCX)Click here for additional data file.Figure S5Boxplots showing the seasonality (dry (blue) and wet (red) season) of the water temperature.(DOCX)Click here for additional data file.Figure S6Boxplots showing the seasonality (dry (blue) and wet (red) season) of the conductivity.(DOCX)Click here for additional data file.Figure S7Boxplots showing the seasonality (dry (blue) and wet (red) season) of the pH.(DOCX)Click here for additional data file.Figure S8Boxplots showing the seasonality (dry (blue) and wet (red) season) of the dissolved oxygen.(DOCX)Click here for additional data file.Figure S9Boxplots indicate the observed stream velocity in Ecuador (red), Ethiopia (green) and Vietnam (blue) at which Chironomidae are found to be present (denoted by P on the left axis) and absent (denoted by A on the left axis).

The fuzzy model determined a DPN degree score (0-10) by the combination of fuzzy sets derived from clinical variables , using if-then rules to combine the inputs with the output sets (Mamdani process), with membership functions determined by a team of 4 DPN specialists. The MCA method grouped 16 DPN-related categorical variables into micro and macro-classes (groups) after the algorithm learned the grouping pattern of the variables in the patients' cohort. A Kohonen map was used to better represent the clusters of variables that could identify different DPN severities.Loss of tactile and vibration perceptions were decisive for classification of DPN severity using the fuzzy system, and its sensitivity and specificity in discriminating patients with and without DPN was very high (ROC=0.985).

Maximum force decreased 39.8 to 45.2% (P < 0.001) in both young and old animals compared with controls, resulting in a dramatic loss of specific force. This increase in CSA and the concomitant decrease in specific force observed in both young and old diaphragm fibers are compatible with an ineffective compensatory hypertrophy in response to the MV. The comparison of the limb muscles fibers from young, middle aged and old animals confirmed the 28 to 32 month rats to be senescent from a skeletal muscle point of view.This study demonstrated an unexpected increase in CSA (These results demonstrate intrinsic changes in diaphragm muscle fibers of significant importance for the prolonged and complicated weaning from MV. Moreover, the increased number of frail diaphragm muscle fibers observed after MV in old age, both controls and mechanically ventilated, offers a further age-related possible mechanism which may be of significant clinical importance.

Two researchers identified budget used in road safety projects with 5-E strategies independently; the kappa analysis was used to test inter-rater reliability. Information from Thai Health Promotion Foundation and Road Safety Fund was also gathered using a developed excel-based template. Semi-structured interviews were conducted among road safety experts. Some mathematical and statistical analyses were applied to evaluate the efficiency of road safety policy.Thailand devoted around 18 billion Baht each year to prevent road traffic accidents. The majority of public budget was allocated to engineering strategies (50%), followed by enforcement (23%), emergency medical services (12%), evaluation (8%) and education (7%). The road safety experts, however, suggested that the strategies of education, enforcement and particularly evaluation are Thailand\u2018s key success factors. Thus, an area-based road safety information system should be developed.

Disablement of a virus's capacity to circumvent the IFN response enables both basic research and various practical applications. However, such IFN-sensitive viruses can be difficult to grow to high-titer in cells that produce and respond to IFN. The current default option for growing IFN-sensitive viruses is restricted to a limited selection of cell-lines (e.g. Vero cells) that have lost their ability to produce IFN. This study demonstrates that supplementing tissue-culture medium with an IFN inhibitor provides a simple, effective and flexible approach to increase the growth of IFN-sensitive viruses in a cell-line of choice. We report that IFN inhibitors targeting components of the IFN response significantly increased virus replication. More specifically, the JAK1/2 inhibitor Ruxolitinib enhances the growth of viruses that are sensitive to IFN due to (i) loss of function of the viral IFN antagonist (due to mutation or species-specific constraints) or (ii) mutations/host cell constraints that slow virus spread such that it can be controlled by the IFN response. This was demonstrated for a variety of viruses, including, viruses with disabled IFN antagonists that represent live-attenuated vaccine candidates , Influenza Virus), traditionally attenuated vaccine strains and a slow-growing wild-type virus (RSV). In conclusion, supplementing tissue culture-medium with an IFN inhibitor to increase the growth of IFN-sensitive viruses in a cell-line of choice represents an approach, which is broadly applicable to research investigating the importance of the IFN response in controlling virus infections and has utility in a number of practical applications including vaccine and oncolytic virus production, virus diagnostics and techniques to isolate newly emerging viruses. Knockout of viral IFN antagonists is also a method of engineering viruses to specifically target cancer cells for oncolytic virotherapy Virus infection triggers the cellular interferon (IFN) response to produce Type 1 IFN's alpha and beta (IFN\u03b1/\u03b2). Secreted IFN\u03b1/\u03b2 can stimulate the JAK-STAT pathway in an autocrine or paracrine manner to activate hundreds of IFN-stimulated genes (ISGs), many of which have antiviral activities that elicit an antiviral state Despite the advantages of disabling a virus's IFN antagonist, it can be difficult to grow such IFN-sensitive viruses to high-titer in tissue culture cells that produce and respond to IFN Inhibitors of the IFN response were prepared as 10 mM stocks in dimethyl sulfoxide (DMSO) and used at the indicated concentrations. Inhibitors were purchased from Selleck Chemicals except MRT68844 and MRT67307, which were gifts of MRC-Technology and Philip Cohen (University of Dundee) respectively. Cell-lines derived from a variety of mammalian species were utilized: human (A549 and MRC5) monkey (Vero), mouse , rabbit (RK13), dog (MDCK) and pig (PKIBRS2). These cells were obtained from the European Collection of Cell Cultures (ECACC) with the exception of the PKIBRS2 cells, which were obtained from the Institute of Animal Health (UK) 4 units/ml of purified \u03b1-IFN to activate the IFN signaling pathway and GFP expression from the IFN response (ISRE) promoter. Forty-eight hours post-IFN stimulation GFP expression and cellular cytotoxicity were measured as described above. Each assay was conducted in triplicate and the mean and standard deviation (StDev) determined.The A549/pr(IFN-\u03b2).GFP and A549/pr(ISRE).GFP reporter cell-lines were used to test the effect of IFN inhibitors on IFN induction or IFN signaling. A549/pr(IFN-\u03b2).GFP were seeded into a 96 well plate and media supplemented with a TBK1 inhibitor or the IKK2 inhibitor (TPCA-1) at the indicated concentrations or equivalent volumes of DMSO. Two hours post-inhibitor treatment cells were infected with a stock of PIV5V\u0394C rich in defective interfering particles (DIs) to optimally activate the IFN induction pathway and expression of GFP under the control of the IFN-\u03b2 promoter Standard plaque assays were conducted in the appropriate cells using a 0.6% (w/v) avicell overlay Eight small molecules that have previously been described to inhibit the cellular IFN response were obtained; four inhibitors that target components of the IFN induction pathway: TBK1 inhibitors BX795, MRT68844, MRT67307 Bunyaviridae family are being developed as attenuated vaccines via NSs knockout Effect of the inhibitors on viral plaque formation was examined using A549 cells infected with recombinant Bunyamwera virus (BUN\u0394NSs), in which the NSs IFN antagonist has been inactivated rendering the virus IFN sensitive The six effective inhibitors were used to examine their effect on BUN\u0394NSs growth kinetics and all six inhibitors significantly improved virus titers . At 48 hWe next sought to determine if two inhibitors targeting different components of the IFN response could further boost BUN\u0394NSs growth if used in combination with each other or to supplement the medium of infected A549/PIV5-V cells. The IKK-2 inhibitor TPCA-1 and JAK1/2 inhibitor Ruxolitinib were tested. However combinations resulted in no further increases in plaque size in A549 cells and in fact a small decrease in plaque size was observed when the inhibitors were used in combination compared to Ruxolitinib or PIV5-V expressing cells alone . One posA limited number of cell-lines have regulatory approval for vaccine manufacture e.g. MRC5 Respiratory Syncytial Virus (RSV) and Influenza are examples of viruses currently being developed as IFN-sensitive attenuated vaccine candidates We also tested two traditional vaccine strains, measles (MeV) Edmonson and the Mumps (MuV) Enders, which have been generated empirically using nonsystematic attenuation methods in vitro. In the initial plaque formation screen the JAK1/2 inhibitor Ruxolitinib was the most effective and hence was taken forward for further study. Moreover, all the results obtained for Ruxolitinib were essentially mirrored with the IKK2 inhibitor TPCA-1 (data not shown). The plaque assays and growth curves performed required incubation with the inhibitor for multiple days. To ensure our results were not affected by loss of activity of the drug, we used the A549/pr(IFN-\u03b2).GFP and A549/pr(ISRE)GFP reporter cell-lines to measure the activity of the drug over time; confirming that the inhibitory effect of both Ruxolitinib and TPCA-1 was stable up to at least 7 days in tissue-culture the cost of the inhibitor and (ii) the harvested virus stocks will contain the inhibitor which may affect experiments to address both basic science questions and regulatory problems for medical applications in humans, although in this latter regard it is noteworthy that Ruxolitinib is approved for clinical treatment of myelofibrosis in vivo, they may also prove useful in studies designed to investigate the importance of the IFN response in controlling virus infections in animal models.These results provide proof of principle that supplementing tissue-culture medium with IFN inhibitors provides a simple, effective and flexible approach to enhance virus growth in cell-lines of choice. IFN inhibitors targeting different components of the IFN response significantly increased replication and yield of a variety of viruses; including examples of potential vaccine candidates with disabled IFN antagonists , traditionally attenuated vaccine strains and wild-type viruses .

Over the past ten years, a number of studies in different model systems have demonstrated that PINK1 and Parkin regulate jointly several processes relevant to maintenance of mitochondrial quality, including mitochondrial trafficking and dynamics, mitophagy and biogenesis. By using a combination of approaches of cell biology, confocal imaging and biochemistry in different cell models, we recently showed that loss of protein import efficiency triggers recruitment of Parkin by PINK1 in proximity of the translocase of outer mitochondrial membrane (TOM). We provided evidence that the degradation of specific TOM subunits plays a key role in initiating the autophagic degradation of damaged mitochondria. We also showed that PINK1 and Parkin interact with the TOM machinery on polarized mitochondria. Our results suggests that this interaction modulates the import of the multifunctional mitochondrion-protective matrix enzyme 17beta-hydroxysteroid dehydrogenase 10, which is depleted in Parkin-deficient mice and Parkinson\u2019s disease patients. Electron and confocal microscopy, and calcium imaging approaches used to characterize the endoplasmic reticulum (ER)-mitochondria interface, a compartment previously linked to neurodegenerative processes, revealed enhanced juxtaposition between these organelles, associated with increased ER-to-mitochondria calcium transfer in cells from Parkin-deficient mice and patients with PARK2 mutations.

The disease is initiated by the activation of the endothelium by various risk factors leading to chemokine-mediated recruitment of immune cells. The uptake of modified lipoproteins by macrophages along with defective cholesterol efflux gives rise to foam cells associated with the fatty streak in the early phase of the disease. As the disease progresses, complex fibrotic plaques are produced as a result of lysis of foam cells, migration and proliferation of vascular smooth muscle cells and continued inflammatory response. Such plaques are stabilized by the extracellular matrix produced by smooth muscle cells and destabilized by matrix metalloproteinase from macrophages. Rupture of unstable plaques and subsequent thrombosis leads to clinical complications such as myocardial infarction. Cytokines are involved in all stages of atherosclerosis and have a profound influence on the pathogenesis of this disease. This review will describe our current understanding of the roles of different cytokines in atherosclerosis together with therapeutic approaches aimed at manipulating their actions. Atherosclerosis is now recognized as an inflammatory disorder of medium and large arteries initiated by risk factors such as high plasma cholesterol levels and hypertension in vitro studies using cell culture model systems have made a major contribution in advancing our understanding of the roles of cytokines in the cellular processes associated with atherosclerosis, the major focus of this review will be on the outcome from studies using animal model systems. In particular, two mouse models, the apolipoprotein (Apo) E-deficient mice and the low-density lipoprotein receptor (LDLr)-deficient mice Cytokines are a diverse group of low-molecular weight proteins with over 100 identified so far. Cytokines are clustered into several classes such as the interleukins (IL), chemokines, colony-stimulating factors (CSF), tumor necrosis factors (TNF), the interferons (IFN) and transforming growth factors (TGF) 2Atherosclerotic plaques tend to form particularly at the inner curvatures and branch points of arteries that are often associated with disturbed blood flow, and is augmented by other factors such as high plasma low-density lipoprotein (LDL) concentration, hypertension and toxins from cigarette smoke The activated ECs release a range of chemokines and other cytokines that then cause the recruitment of circulating immune cells, particularly monocytes and T lymphocytes 3C, XC) high [express high levels of CC-chemokine receptor (CCR)-2, believed to be pro-inflammatory in nature and their levels increase in hyperlipidemia) and less frequent Ly6Clow [express CX3C-chemokine receptor 1 and perceived to carry out a homeostatic function) high monocytes involves immobilization of CCL5 and CXCL1 on proteoglycans and P-selectins on ECs Chemokines are a large family of structurally related, chemoattracting cytokines that are divided into subgroups on the basis of the position of the amino terminal cysteine residues is also associated with reduced macrophage recruitment and the alternatively activated M2 (thought to be derived from Ly6Clow-monocytes and produces anti-inflammatory cytokines such as IL-10 and TGF-\u03b2) that aid in the resolution of inflammatory responses \u2212/\u2212 model system drives M2 macrophage polarization and inhibits atherosclerosis progression In the arterial intima, monocytes can differentiate to macrophages or dendritic cells (DCs) depending on the cytokine signal received with macrophage colony-stimulating factor (M-CSF) a major facilitator of macrophage differentiation LDL tends to diffuse passively through EC junctions and its retention is aided by interaction of its apoB moiety with components of the extracellular matrix such as proteoglycans Macrophages express pattern recognition receptors (PRRs), such as scavenger receptors (SRs), toll-like receptors (TLRs) and nucleotide-binding oligomerization domain (NOD)-like receptors (NLR), that participate in foam cell formation and/or elicit an inflammatory response against foreign particles or endogenously produced danger signals in vivo; for example, IFN-\u03b3 and TNF-\u03b1 promote this whereas IL-1RA and IL-33 are inhibitory.

Spatial aggregate of intensity and frequency of extreme rainfall events over Central India are significantly increasing, while at local scale they are spatially non-uniform with increasing spatial variability. The reasons behind such increase in spatial variability of extremes are poorly understood and the trends in mean monsoon rainfall have been greatly overlooked. Here, by using multi-decadal gridded daily rainfall data over entire India, we show that the trend in spatial variability of mean monsoon rainfall is decreasing as exactly opposite to that of extremes. The spatial variability of extremes is attributed to the spatial variability of the convective rainfall component. Contrarily, the decrease in spatial variability of the mean rainfall over India poses a pertinent research question on the applicability of large scale inter-basin water transfer by river inter-linking to address the spatial variability of available water in India. We found a significant decrease in the monsoon rainfall over major water surplus river basins in India. Hydrological simulations using a Variable Infiltration Capacity (VIC) model also revealed that the water yield in surplus river basins is decreasing but it is increasing in deficit basins. These findings contradict the traditional notion of dry areas becoming drier and wet areas becoming wetter in response to climate change in India. This result also calls for a re-evaluation of planning for river inter-linking to supply water from surplus to deficit river basins.

We have proposed the fluorescence anisotropy (FA) and fluorescence intensity (FI) assay to investigate fluorescent ligand binding properties to different GPCRs . The implementations of budded baculoviruses that display G protein-coupled receptors on their surfaces have significantly increased sensitivity and applicability of these assays . The developed novel assay systems opened new possibilities for real-time monitoring of ligand binding to their receptors for understanding their particular kinetic properties.

It contributes to stability and basic movements like rotation and elevation of the arm. Shoulder fusion should not be accepted even for total palsy, and nerve repair should be recommended as long as an available donor nerve exists.In planning the reconstructive procedure for shoulder function, accurate biomechanical analysis of individual glenohumeral (GH) and scapulothoracic (ST) joint is imperative, especially concerning serratus anterior muscle (SA) function.Priority of nerve repair and selection of donor nerve for shoulder function are the most important key points especially in C5~7, C5~8 and total palsy depending on accompanying reconstruction of elbow and finger function including conventional nerve transfer (NT) and free muscle transfer.Many previous articles of shoulder reconstruction with nerve repair following brachial plexus injuries were concluded from global shoulder motion that combine GH and ST motion, and emphasized only suprascapular nerve (SSN) repair. I emphasized SSN and long thoracic nerve (LTN) repair except in C56 palsy. The axillary nerve (Ax) can be ignored because simple AX palsy does not result in serious paralysis of shoulder function.Postoperative range of shoulder motions following SSN repair, in decreasing order according to individual donor nerve was; phrenic never (PN), spinal accessory nerve (SAN), C5 root and contralateral C7 (CC7 ) root. For LTN repair; the decreasing order of post operative range of shoulder joint movements were intercostal nerve (ICN), PN, SAN, C5 root and CC7 root. PN to SSN and ICN to LTN transfer achieved the most satisfactory outcome in total palsy; however, other combinations of nerve repair and AX repair did not provide significantly better shoulder motion.Dynamic shoulder XP is useful to differentiate between GH and ST motion for pre- and postoperative evaluation.I will introduce our techniques of the representative nerve repairs for shoulder reconstruction."} +{"text": "Wall shear stress (WSS) may be associated with the onset and development of aortopathy in the presence of bicuspid aortic valve (BAV) .

The life cycle of KSHV includes a latent and a lytic/productive phase that both contribute to tumorigenic activity. Major threats for infected tumor cells are attacks of the immune system and the induction of endogeneous cell death programs in response to the virus infection. KSHV opposes these threats for example by hiding from the immune attack by entering the latent infection phase where only few genes are expressed and replication is absent or in the productive phase by the downregulation of major histocompatibility complex class I on the surface of infected cells. Moreover, KSHV uses several different strategies to counteract endogenous cell death programs such as apoptosis and necroptosis.KSHV encodes more than 87 ORFs (open reading frames) and numerous ribosomal-loaded not previously annotated RNAs . ORF actIn another RTCM-based study the effects of all KSHV-encoded genes on the inhibition of p53 were investigated.

We aimed to develop a prospective study that evaluated the relation between serum levels of 8-hydroxy-2-deoxiguanosine (8OHdG) and total antioxidant status (TAS) in patients with membranous glomerulopathy associated with HBV infection.The study included a group of 18 patients with chronic infection with HBV and membranous nephropathy with nephrotic syndrome, without renal failure (eGFR >60mL/min/1.73sqm), and a group of 20 patients with chronic infection with HBV without membranous glomerulonephritis. The patients did not receive any treatment for the mentioned diseases before the inclusion in the study. The groups were similar for demographic and nutritional status characteristics. The assessment of 8OHdG, a metabolite of oxidative damage of DNA, was made by ELISA method. TAS was determined by spectrophotometric method.In patients with chronic HBV infection and membranous nephropathy, 8OHdG (ng/mL serum) had higher levels than in patients with chronic HBV infection without renal disease . Serum levels of TAS (mmol/L serum) were significantly lower in patients with membranous glomerulopathy compared with those without nephropathy . A statistically strong negative correlation was determined between 8OHdG and TAS in patients with glomerulopathy associated with HBV infection.The negative association between serum levels of 8OHdG and TAS in patients with membranous nephropathy induced by HBV infection suggests an important role of oxidative stress in the development of renal diseases.

Curiously, the highly threatened Platanista is restricted today to freshwater river systems of South Asia, yet nearly all fossil platanistoids are known globally from marine rocks, suggesting a marine ancestry for this group. In recent years, studies on the phylogenetic relationships in Platanistoidea have reached a general consensus about the membership of different sub-clades and putative extinct groups, although the position of some platanistoid groups has been contested. Here we describe a new genus and species of fossil platanistoid, Arktocara yakataga, gen. et sp. nov. from the Oligocene of Alaska, USA. The type and only known specimen was collected from the marine Poul Creek Formation, a unit known to include Oligocene strata, exposed in the Yakutat City and Borough of Southeast Alaska. In our phylogenetic analysis of stem and node-based Platanistoidea, Arktocara falls within the node-based sub-clade Allodelphinidae as the sister taxon to Allodelphis pratti. With a geochronologic age between \u223c29\u201324 million years old, Arktocara is among the oldest crown Odontoceti, reinforcing the long-standing view that the diversification for crown lineages must have occurred no later than the early Oligocene.The diversification of crown cetacean lineages occurred throughout the Oligocene, but it remains an ongoing challenge to resolve the phylogenetic pattern of their origins, especially with respect to stem lineages.

We note that, for Phocageneus venustus, we followed Waipatia and Otekaikea is consistent with Waipatia, differing from the results in Waipatia maerewhenua and Otekaikea marplesi. Our results are consistent with Squalodelphis fabianii as a basal member of Platanistoidea and an unnamed clade of Notocetus vanbenedeni + Phocageneus venustus as the sister group to Platanistidae. A more detailed coding of Squalodelphinidae in future work, especially one that includes Huaridelphis raimondii, will provide more insight into the relationships among this group.Our phylogenetic analysis herein addresses some of the shortfalls of previous studies by including type genera belonging to all potential platanistoid families that have been presented in recent phylogenetic analyses i.e., . We resoWe diagnose a node-based Platanistoidea by the following synapomorphies: moderately elevated coronoid process (character 33*); premaxillae >65% of width of rostrum at antorbital notches (character 51*); alisphenoidal-squamosal suture coursing along groove for mandibular branch of trigeminal nerve in ventral view (character 147[1]); lateral groove or depression with profile of periotic becoming slightly to markedly sigmoidal in dorsal view (character 166[1]); anteroposterior ridge on dorsal side anterior process and body of periotic (character 167[1]); parabullary sulcus on the periotic weakly to strongly curved and c-shaped ; and ventral surface of the posterior process of the periotic not flat along a straight path perpendicular to its long axis Of these synapomorphies, the two marked by an asterisk (\u2217) are equivocal across the group, demonstrating character state reversals or independent origins . Two characters are ambiguous and show independent origins (characters 169 and character 191), but we argue remain useful for characterizing this group.Allodelphis pratti, where there is no distinguishable rim lateral to the posterior process and separated by a sulcus , the anterolateral convexity of the tympanic bulla with anterolateral notch (character 196), and the ventral groove (median furrow) of bulla anteriorly (character 212) are all ambiguous characters, represented by two states each across Platanistoidea. All of the latter traits are present in Allodelphis pratti and Zarhinocetus errabundus, with perhaps the exception of the ventral groove of the anterior surface of the bulla in Allodelphis pratti, which could not be determined from the photos of the referred specimen (UCMP 83791) provided by Only one of the six synapomorphies presented by a sulcus . In ZarhSqualodelphis fabianii and an unnamed sub-clade that includes Notocetus vanbenedeni + Phocageneus venustus + Platanistidae. Allodelphinidae in our study is supported by the following synapomorphies: rostral constriction anterior to the antorbital notch (character 9[1]); premaxillae in dorsal view contacting along midline for approximately half of the entire length of the rostrum and partially fused (character 14[3]); buccal teeth entocingulum absent (character 24[1]); greatest diameter of largest functional tooth <3% of greatest width of maxillae at postorbital processes (character 25[2]); angle of anterior edge of supraorbital process and the median line oriented anteromedially (character 35[1]); dorsolateral edge of internal opening of infraorbital foramen formed by maxilla (character 43[0]); posterolateral sulcus shallow or absent (character 57[1]); lack of premaxillary crest or posterior maxillary crest adjacent to nasals (character 72[0]); temporal fossa roofed over by lateral expansion of the maxillae (character 101[1]); palatines partially covered by pterygoid dividing it into medial and lateral exposures (character 121[1]); lateral lamina of palatine (character 122[1]); lateral end of groove for mandibular branch of trigeminal nerve wrapping laterally around posterior end of pterygoid sinus fossa and opening anteriorly (character 148[0]); lack of anterior bullar facet (character 172[1]); elevated caudal tympanic process of periotic with ventral and posterior edges forming a right angle in medial view (character 178[1]); tubular fundus of internal acoustic meatus (character 182[1]) angle between posterior process of periotic and long axis of pars cochlearis \u2264135\u00b0 from dorsal or ventral view (character 189[1]); and ventral surface of posterior process of periotic convex along a straight path perpendicular to its long axis (character 191[2]). Based on the published descriptions and illustrations provided by Allodelphis woodburnei, Ninjadelphis ujiharai, and Zarhinocetus donnamatsonae) each possess all of the allodelphinid synapomorphies presented by our analysis.Our analysis recovered Allodelphinidae as a well-supported sub-clade within a node-based Platanistoidea, rooted in a polytomy with Waipatia and Otekaikea where the palatine is poorly preserved or missing), and a tympanic bulla with elongated and pointed anterior process, among others. Nevertheless, our diagnosis is consistent with Allodelphis pratti where only one premaxilla is separated from the corresponding nasal by a tiny exposure of maxilla, to further \u201cderived\u201d states in Ninjadelphis and Zarhinocetus where the premaxillae are further retracted anteriorly onto the facial region and away from the nasals. However, it is unclear in the more \u201cprimitive\u201d state of Allodelphis whether the lack of contact between the premaxilla and nasal could be a result of diagenetic breakage, or individual variation. Furthermore, speculations on the more \u201cderived states\u201d in taxa such as Ninjadelphis, are based on specimens with incomplete premaxillae. In Goedertius oregonensis, the premaxillae are not separated from the nasals. This condition is likely also true for Arktocara yakataga: although the nasals are missing, the premaxillae directly abut the nasal fossa of the frontal, and therefore would most likely have been in direct contact with the nasals. Further extensive comparative work on allodelphinid taxa will heAllodelphis pratti, in part due to obstruction by unprepared matrix. However, in Arktocara yakataga, though there is no obvious indication of a postorbital lobe of the pterygoid sinus, the deep and broad fossa surrounding the ventral infraorbital foramen and the sphenopalatine foramen anteromedial of the orbit suggests the presence of a preorbital lobe.Second, Allodelphis pratti was referred to the Platanistidae by Ninjadelphis is the only allodelphinid specimen with an associated scapula, and it is missing the coracoid process. This agreement with Otekaikea huata), the character may still be relevant for diagnosing Platanistoidea . Though the type specimen of Arktocara lacks tympanoperiotics, it is closely allied with Allodelphis pratti, whose periotic shares three more of the platanistoid synapomorphies: presence of lateral groove or depression with the profile of the periotic becoming slightly to markedly sigmoidal in in dorsal view (character 166[1]); anteroposterior ridge developed on anterior process and body of periotic in dorsal view (character 167[1]); and a curved C-shaped parabullary sulcus . Therefore, in the absence of tympanoperiotics associated with new cranial material of Arktocara, we are confident that these elements would share many features with Allodelphis pratti, the sister taxon of Arktocara.Of the 7 supporting synapomorphies for Platanistoidea in our study, none of the unequivocal synapomorphies are preserved and demonstrated on the skull of Arktocara in morphology is Allodelphis pratti , (B) Platanista gangetica (USNM 23456) and (C) USNM 214911, an undescribed platanistoid.

Overall subjects fulfilled criteria for ICUAW on their first day of being awake and significantly improved their MRC score and grip strength until their ICU discharge. Surprisingly we could not show direct group differences between EMS- and control group for MRC score and grip strength. By focusing separately on the course of strength for EMS- and control group we found an increase in MRC score for both groups between the first and second measurement.Grip strength in nonEMS treated patients rose significantly whilst patients receiving EMS couldn't show significant improvements between measurements.Our patients managed to increase their grip- and general strength levels significantly from their first day of being adequately awake until the day of their ICU discharge. Further subgroup analysis however indicates that EMS therapy may not be more beneficial in increasing grip or MRC-measured strength compared to the standard physiotherapy protocol within our study. The missing grip strength improvement of the EMS group between the first day of being awake and ICU discharge may be attributed to greater muscle strength at time of awakening without significant power to show group differences.DFG KFO 192/2 TP3"} +{"text": "Respiratory muscle weakness is common in mechanically ventilated patients and impairs liberation from ventilation.

Analysis of SFV complete sequences obtained from 5 of these individuals had revealed that the env gene was the most variable one. Furthermore, recombinant SFV strains have been recently shown; some of them involved the env gene. This led us to investigate the env gene variability of zoonotic SFV strains, looking especially for possible recombinants. We sequenced the complete or the surface glycoprotein region (SU) of SFV env gene amplified from blood DNA of: 1) a series of 40 individuals from Cameroon or Gabon infected with a gorilla or chimpanzee FV strain; 2) one gorilla and 3 infected chimpanzees living in the same areas than the hunters. All sequences were aligned and analysed by phylogenetic (neighbour-joining and maximum likelihood) and recombinant detection methods . Phylogenetic analyses revealed the existence of two different env variants among both gorilla FV and chimpanzee FV strains. These were present in zoonotic as well as in NHP strains. These variants differ greatly (more than 30% variability) in a 750 bp long region located in the receptor binding domain of the SU; the rest of the gene is very conserved (less than 5% variability among strains from the same species).

Indeed, type 2 diabetic patients account for the majority of individuals with chronic kidney disease requiring renal replacement therapy. This not only suggests inadequacy of current drug therapies but also failure of endogenous protective mechanisms. Stem cells are known to play pivotal roles in repair and regeneration of damaged/dysfunctional tissues. Our initial observations suggested that initiation and progression of type 2 diabetes mellitus is associated with progressive reduction in endothelial progenitor cells in the obese diabetic db/db mice. Thus, the present study was intended to more fully explore the status of components of stem cells in the setting of type 2 diabetic nephropathy and whether the diabetic milieu affects the survivability of these cells.Male 16-week-old obese diabetic db/db mice (and their db/m controls) were used for this study. Accordingly, indices of glycemic status , kidney function were determined in the context of assessment of components of stem cells in peripheral blood and renal tissue. In addition, we measured apoptotic cell death in components of stem cells.+Ckit+CD31-) mesenchymal stem cells and endothelial/epithelial progenitor cells compared to those of db/m controls. Further, kidney cells prepared for experimental groups also showed reductions in components of stem cells. Using annexin V in association with markers of each component of stem cells revealed significant increases in apoptosis for HSC, MSC and EPCs in cells prepared for kidneys of db/db and db/m mice. Collectively, the results suggest that apoptosis of components of stem cells likely contributes to eventual manifestation of renal failure in type 2 diabetes mellitus.The db/db mice showed significant increases in insulin resistance index and hemoglobin A1c in association with marked increase in albuminuria but reduction in creatinine clearance in association with significant increases in apoptotic and necrotic cell death of kidney cells. The peripheral blood cells of db/db mice displayed significant reduction in hematopoietic stem cells (HSC; Sca1The observation of a similar pattern of decline in stem cell components in the peripheral blood and the kidney suggests that monitoring of blood levels of stem cells subsets may be predictive of failure of their renoprotective features. Further, strategies aimed at reducing apoptosis of stem cell components and \u201cempowering\u201d them through genetic modulations could potentially serve as effective strategies to prevent end-stage renal failure in type 2 diabetic patients."} +{"text": "Chronic kidney disease (CKD) caused by renal fibrosis is an important public health concern. It is therefore necessary to understand the molecular pathogenesis of renal fibrosis in order to develop novel therapeutic strategies. KLF4 is the most extensively studied factor among the various members of the Kr\u00fcppel-like factor (KLF) family of zinc finger-containing transcription factors. Many studies have demonstrated that KLF4 inhibits the activation of myofibroblasts and exerts an inhibitory effect on fibrosis. However, other studies have indicated that KLF4 may promote renal fibrosis. These controversial results suggest that KLF4 may be crucially involved in the development of renal fibrosis, although the underlying mechanism(s) remain unclear. Here, we summarize the recent progress made in understanding the role of KLF4 in renal fibrosis. Together, these findings suggest that KLF4 may participate in the development of renal fibrosis, but that its inhibition of fibrosis is greater than its promotion of the condition, which suggests that KLF4 may serve as a novel therapeutic target for renal fibrosis. Renal fibrosis is characterized by excessive proliferation of fibroblasts and increased deposition of extracellular matrix (ECM), which together lead to extensive scarring (fibrotic tubular and glomerular sclerosis), renal artery stenosis and chronic inflammatory cell infiltration family consists of 17 zinc finger-containing transcription factors, among which KLF4 is the most extensively studied is an important participant in a broad spectrum of inflammatory networks that regulate the cytokine activity in renal fibrosis regulates the expression of VSMC differentiation markers by cooperating with its co-activator, myocardin, or its co-repressor, phosphorylated KLF4 (Wang et al., renal physiological functions and the progression of fibrosis (Chen et al., in vivo models of unilateral ureteral obstruction, a decrease in KLF4 expression was observed (Chen et al., Recently, Chen et al. showed that KLF4 was indeed involved in the regulation of The role of KLF4 in renal fibrosis is complex.

During the past few decades analysis of cardiac function based on the heart rate variability has attracted great attention, resulting in more than 17000-publications (PubMed list). However, it is still controversial about the underling mechanisms of HRV. In this study, we performed both linear (time domain and frequency domain) and nonlinear analysis of HRV data acquired from humans and animals to identify the relationship between HRV and heart rate (HR). The HRV data consists of the following groups: (a) human normal sinus rhythm (n = 72); (b) human congestive heart failure (n = 44); (c) rabbit sinoatrial node cells ; (d) conscious rat (n = 11). In both human and animal data at variant pathological conditions, both linear and nonlinear analysis techniques showed an inverse correlation between HRV and HR, supporting the concept that HRV is dependent on HR, and therefore, HRV cannot be used in an ordinary manner to analyse autonomic nerve activity of a heart. Greek Physicians and scientists were the pioneers who measured pulse rate; however, it was not much accurate till the invention of pulse watch in 1707 .The autonomic nervous system (ANS) controls heart rate, hear rate variability (HRV) and breathing. Heart Rate Variability (HRV) analysis is a non-invasive technique used to evaluate the balancing action of sympathetic and parasympathetic branches of the autonomic nervous system , 4,5. OvOver the last 35 years, various linear and non-linear techniques have been developed to extract the valuable information from cardiac interbeat interval time series data, aiming to help clinician for prognostication of illness and assessing malfunctioning of the autonomic nervous system. However, often contradictory results have left clinicians skeptical and there exists no clear consensus about HRV analysis measures . In 1996The main purpose of this study is to identify the relationship of HR with both linear and nonlinear metrics of HRV. The human and animal data sets were analysed under following conditions: (a) human normal sinus rhythm n = 72); (b) human congestive heart failure (n = 44); (c) rabbit sinoatrial node cell (SANC) (n = 67); and (d) conscious rat (n = 11). Both nonlinear and linear methods showed that HRV is primarily dependent on HR. There is an inverse correlation between the HRV and HR: a larger HRV was correlated with a lower HR, and the vice versa. Such a correlation was observed both in the human data at variant pathological conditions and variant animal species.

LF is a band of power spectrum ranging between 0.04 and 0.15 Hz. This parameter reflects both sympathetic and parasympathetic function. HF is a band of power spectrum range between 0.15 and 0.4 Hz. Generally this measure reflects parasympathetic function. Total power is a short term estimate of the total power of power spectral density in the range of frequencies between 0 and 0.4 Hz.

We wanted to assess the rate of positive CTPA specifically amongst oncology patients with suspected PE in our teaching hospital.We retrospectively analysed all consecutive CTPAs carried out for clinically suspected PE over a 12 month period in all patients under our oncology services.A total of 230 oncology patients had a CTPA to exclude PE and 40 were positive (17.4%).

Aspiration pneumonia was diagnosed by: 1) clinical and radiologic features of pneumonia and 2) pathologic findings of aspiration and acute bronchopneumonia sometimes accompanied by microabscesses and granulomatous inflammation at postmortem examination. Aspiration pneumonitis was diagnosed by: 1) acute onset of respiratory symptoms with new pulmonary infiltrates on chest imaging and 2) pathologic evidence of acute lung injury combined with the presence of foreign material or foreign body giant cell reaction at postmortem examination. Large airway obstruction was defined as acute respiratory failure related to the presence of large particulate material causing large airway obstruction confirmed on postmortem examination. Patients who died from drowning and amniotic fluid aspiration were excluded. Other forms of aspiration-related pulmonary syndromes including diffuse aspiration bronchiolitis and exogenous lipoid pneumonia were not encountered in this autopsy study. We identified the time of aspiration event based on available medical history as well assessment of clinical course and emergence of new pulmonary infiltrates on chest imaging. The current study was approved by the Mayo Foundation Institutional Review Board .Medical records were examined in detail and the following data were retrieved: age, sex, clinical presentation, risks for aspiration, radiologic findings, events leading up to death, and autopsy findings. We also determined clinician's diagnosis as to the cause of death based on review of all available medical records including clinical notes as well as the clinician diagnoses listed on death certificates. The clinician diagnosis and the type of aspiration-related pulmonary syndrome causing death was assigned based on a review of all available data by consensus of the two authors (XH and JHR).Continuous data are presented as median and range , when appropriate, and frequency, percentages for categorical variables.Of 57 patients with aspiration-related deaths, 39 (68%) were male Table 1.One or more precipitating factors for aspiration were identified in all 57 patients and mainly included depressed consciousness in 26 patients (46%), dysphagia in 25 patients (44%); 6 patients had two risk factors Table 2.The type of aspiration-related pulmonary syndrome leading to death were classified as aspiration pneumonia in 26 (46%), aspiration pneumonitis in 25 (44%), and large airway obstruction in 6 (11%). All six large airway obstruction cases died within 72 hours of aspiration. Among the 19 aspiration pneumonitis cases in whom the time of aspiration event could be identified retrospectively, 14 (74%) died within 72 hours. In contrast, among 22 cases of aspiration pneumonia in whom the time of initial aspiration event could be identified, only 6 (27%) died within 72 hours.Among 27 patients who suffered aspiration in the hospital were 10 aspiration pneumonia, 14 aspiration pneumonitis and 3 large airway obstruction cases. In the remaining 30 patients with aspiration likely occurring outside of the hospital were 16 aspiration pneumonia, 11 aspiration pneumonitis and 3 large airway obstruction cases.Main symptoms recorded preceding death included dyspnea (63%), decreased consciousness (19%) Table 1.Fifty-three patients (93%) underwent chest radiography, 16 of whom also had undergone chest computed tomography (CT); four patients had no chest imaging available prior to death. Bilateral distribution of parenchymal abnormalities was seen in 44 patients (83%). The predominant radiologic findings were patchy alveolar infiltrates and/or atelectasis in 46 patients (87%); remaining seven patients exhibited mixed patterns of interstitial, consolidative, and ground-glass opacities. These chest imaging findings were relatively nonspecific.During the hospital course, 35 patients underwent invasive mechanical ventilation (non-invasive ventilation in two patients including one with aspiration pneumonia and another with aspiration pneumonitis); 20 patients had aspiration pneumonitis, 14 patients had aspiration pneumonia and, 1 patient had large airway obstruction. Extracorporeal membrane oxygenation was also employed in one patient with aspiration pneumonitis. Bronchoscopy was performed in 16 patients, including one procedure performed at an outside hospital and one patient who underwent the procedure twice. Three of these patients were found to have evidence of aspiration and 12 patients underwent the procedure for clearance of airway secretion; the bronchoscopic inspection was normal in the remaining patient.Staphylococcus aureus , Enterobacter species (two patients), Streptococcus(one patient), Nocardia (one patient), Klebsiella pneumoniae complex coexisting with Enterococcus (one patient), and Candida (one patient with lymphoma). Microbial culture results were available in 14 patients with aspiration pneumonitis , 9 of whom had potential pathogens identified including Staphylococcus aureus , Escherichia coli , Enterobacter species , Klebsiella species (two patients), Citrobacter koseri (one patient) and Streptococcus species (one patient). Antimicrobial therapy had been administered to 23 patients (88%) with aspiration pneumonia and 22 patients (92%) with aspiration pneumonitis, including three in each group treated with antifungal drugs.Microbial culture results were available in 19 patients with aspiration pneumonia, nine of whom had potential pathogens identified including Aspiration was included among diagnostic possibilities by clinicians at the time of death for 38 patients (67%). Nineteen patients (33%) whose aspiration was clinically unsuspected included nine who died from aspiration pneumonitis, nine with aspiration pneumonia, and one with large airway obstruction Table 3.With the exception of few reported cases, aspiration-related deaths have not been methodically investigated Our data also show that dysphagia related to neurologic disorders comprise the commonest precipitating factor for aspiration-related deaths, followed by depressed consciousness related to sedation. These findings are in agreement with prior studies showing neurologic disorders and sedation to be common precipitating factors for aspiration Dyspnea was the most common symptom recorded for patients in this study and is similar to a prior study describing the presence of this symptom in almost half of 36 aspiration cases confirmed on lung biopsy specimens Aside from large airway obstruction-related death which is very familiar to clinicians According to our data, aspiration pneumonia is the most common type of aspiration-related pulmonary syndrome leading to death. There were more patients with underlying neurological disorders in our study for whom the median age was 72 years old compared to two prior studies Staphylococcus aureus, Enterobacter species rather than anaerobes. This was similar to that previously reported in the literature Our data demonstrated the common isolated pathogens in aspiration pneumonia were Pathogenic bacteria were recovered in a portion of patients with aspiration pneumonitis, a disease entity generally thought to involve aspiration of sterile gastric contents. There are several potential explanations for this finding. Any form of aspiration is likely to include entrance of oral secretions into the lung. Emerging data on human microbiota have demonstrated that multiple species of bacteria can exist in the stomach as well as lungs of healthy individuals Irwin and colleagues Aside from the issue of correctly diagnosing aspiration-related syndromes, our study has some implications on the prevention of aspiration-related deaths. The patients at risk appear to be identifiable such as those with neurologic impairment and dysphagia. Optimal strategies in managing patients identified to be at risk generally require multidisciplinary expertise in maintaining adequate hydration and nutrition while minimizing the risks of aspiration. These options many include tube feeding, oral and bronchial hygiene measures, positioning, antimicrobial and other pharmacologic therapies This study included consecutive patients undergoing autopsy during a nine year period and the diagnostic criteria were based on combined clinical and autopsy findings. We, however, acknowledge that the limitations of this study including the retrospective design which limited the analysis to clinical data available in medical records and autopsy results. There are likely many patients who died from aspiration but did not undergo a postmortem examination and were undiagnosed. There is a selection bias in autopsy studies which tend to enrich for atypical and diagnostically challenging cases. Microbiology data were limited to standard respiratory cultures obtained at postmortem examination and may not have recovered some pathogens such as anaerobic bacteria. Furthermore, aspiration pneumonia and aspiration pneumonitis can sometimes be difficult to distinguish.Aspiration-related deaths most commonly occur in the elderly with identifiable risks and often manifesting bilateral pulmonary infiltrates. In one-third of these patients aspiration as the cause of death was unsuspected by clinicians."} +{"text": "Natural killer (NK) cells are highly effective in controlling tumour growth, in mice, but have no significant effect in humans. The reason(s) of this phenomenon is(are) unclear.The effects of cancer cells on NK cells during target-effector cell conjugation was investigated utilising standard immunological methods including flow cytometry, chromium release and enzyme-linked immunosorbent assays while gene expression was evaluated by quantitative reverse transcriptase-polymerase chain reaction.We found that this phenomenon was associated with the different susceptibility of human and mouse NK cells to autologous tumour cell-induced NK cell abnormalities (NKCA). The latter includes CD16 down-regulation and NK cell depletion. Induction of NKCA by leukaemia and solid tumour cells was influenced neither by IL2 treatment nor by HLA class I antigen expression, but was abrogated by a 10 day culture. Following a 10 day of PBMCs culture, NK cells became resistant to leukaemia and solid tumor cell induced NKCA but maintained their cytotoxic activity. Actinomycin D restored the susceptibility of long term NK (LTNK) cells to NKCA suggesting that the generation of resistance to NKCA required RNA transcription. TAPI-0, a functional analogue of the tissue inhibitor of metalloproteinases (TIMP) 3 inhibited cancer cell induced NKCA underlying a role for a restricted number of metalloproteinases in the generation of this phenomenon. Finally, we found an association of TIMP3 gene and protein over-expression with the reduced susceptibility of LTNK cells to cancer cell induced NKCA.This study provides evidence that TIMP3 plays a role in the protection of LTNK cells from cancer cell induced NKCA."} +{"text": "Lohith et al. recently identified increased metabotropic glutamate receptor 5 (mGluR5) expression in the frontal cortex (FC) of subjects with fragile X syndrome.

Recent findings suggest that hypoxic cancer cells derive the energy that they need through glycolysis using glucose mobilized from intracellular glycogen reserve. Glycogen phosphorylase (GP) is the major rate-determining enzyme for glycogen mobilization in many normal cells under the condition of starvation or physical exercise. The lysosomal alpha-glucosidase (GAA) has also been implicated in glycogen mobilization since deficiency of this enzyme is known to result in Glycogen Storage Disease Type II (Pompe disease). Although a role for GP in the mobilization of glycogen by cancer cells depleted of oxygen had been demonstrated, whether a similar role for GP (and GAA) could be demonstrated under deprivation of both glucose and oxygen is not yet known. This issue is addressed in this study by examining the intracellular level of glycogen in the absence and presence of pharmacological inhibitors of GP and/or GAA.2) in the presence or absence of glucose for 3 hours.

Mutations in TDP43 have been found to be causative of a proportion of ALS cases reinforcing the primary importance of this molecule in disease pathogenesis. The pathogenic mechanism by which TDP43 acts is unclear, and both loss of nuclear function (LOF) and gain of function (GOF) mechanisms have been proposed. We here discuss how we used muscle tissue, which provides high quality RNA of patient disease tissue, to investigate the consequences of TDP43 mislocalization. Further, we characterize two novel mouse TDP43 mutant lines, carrying ENU-induced mutations in order to study the effects of TDP43 mutations expressed at physiological levels in the mammalian central nervous system. One mutation (deltaRNA) strongly reduces the RNA-binding capacity of the protein; the second mutation (C-TERM) is in the glycine-rich C-terminal domain where the majority of human pathogenic mutations are found.

Magnetic resonance imaging (MRI) has been previously used to characterize BAV hemodynamics. However, studies have been hampered by the need for lengthy manual data analysis thereby limiting reproducibility and/or integration into a clinically feasible workflow.This work develops and applies a novel semi-automated technique to characterize geometry and hemodynamics of the aorta and the aortic valve based on 2D bSSFP cine and 4D flow MRI data. The protocol was applied to a cohort of 30 BAV and 30 control subjects. The table summarizes the preliminary analysis of the demographics of the subject cohort.

Spontaneous colonization of new species in the control treatment without seed addition increased realized species richness and functional richness (FRic), indicating continuously denser packing of niches. Seed addition resulted in forced colonization and increased realized species richness, FRic, functional evenness (FEve) and functional divergence (FDiv), i.e. higher abundances of species with extreme trait values. Furthermore, the colonization of new species led to a decline in FEve through time, suggesting that weaker competitors were reduced in abundance or excluded. Communities with higher initial species richness or with longer time since cessation of weeding were more restricted in the entry of new species and showed smaller increases in FRic after seed addition than other communities. The two assembly-history treatments caused a divergence of species compositions within communities originally established with the same species. Communities originally established with different species converged in species richness and functional trait composition over time, but remained more distinct in species composition.Contrasting biotic processes increase functional convergence between communities initially established with different species. Historical contingency with regard to realized species compositions could not be eradicated by cessation of weeding or forced colonization and was still detectable 5 years after application of these treatments, providing evidence for the role of priority effects in community assembly. A deeper insight into the mechanisms which control community assembly is central to understand ecosystem functioning and the maintenance of biodiversity. Functional diversity, i.e. the extent of trait differences among co-occurring species In natural ecosystems, the importance of biotic processes causing trait convergence and divergence in community assembly is difficult to disentangle because abiotic processes may also cause trait convergence or counterbalance biotic trait divergence In the present study, we used experimental plots of a grassland biodiversity experiment cessation of weeding after six years (2007), no seed addition,(S6+) cessation of weeding after six years (2007), seed addition (2005),(S3\u2212) cessation of weeding after three years (2004), no seed addition,(S3+) cessation of weeding after three years (2004), seed addition (2005),(S0\u2212) never weeded, no seed addition, and(S0+) never weeded, seed addition (2005).Plots were mown twice per year and the mown plant material was removed.Species richness, species identities and visually estimated species cover using a decimal scale A trait matrix comprising species mean traits related to spatial and temporal niche dimensions and to strategies of regeneration was compiled for all observed species based on information in the floristic literature Bray-Curtis dissimilarities n-dimensional trait space occupied by the species in a community n-dimensional trait space n-dimensional trait space Measures of functional trait diversity quantify the distribution of species in a multidimensional space whose axes are defined by functional characteristics.

Block and plot identity, subplot pair and subplot were treated as random factors in a nested sequence. Although the factors species richness and number of functional groups are nearly orthogonal in the Jena Experiment, the design of the experiment is not completely balanced because it is not possible to vary species richness and functional group number completely independently. Starting from a constant null model the fitting sequence of fixed terms followed the a-priori hypotheses of the biodiversity experiment starting with the number of initially established species (log-linear term), the number of functional groups (linear term), factors for the split-plot variables colonization period (with three factor levels) and seed addition (with two factor levels) and their interactions with the main experimental factors.

We used the opportunity to study biotic processes of community assembly under relatively homogeneous environmental conditions in split-plots of a large grassland biodiversity experiment opened for colonization by new species and removed dispersal limitation through a seed addition treatment Species gain and increase in functional richness (FRic) after the opening of experimental communities for colonization by new species was reduced by a higher number of initially established species and a longer colonization period (shorter duration of weeding). The negative effects of a higher initially sown plant diversity on the spontaneous colonization of new species may be attributable to the lower stability of low-diverse communities even in the absence of weeding Functional richness (FRic), which quantifies the volume of functional space filled by a community, increased in parallel to species gain in sub-plots without seed addition, but the increment of FRic was flattened in subplots with a higher number of initially sown species . The conPrevious studies have reported that experimental communities initially sown with different plant diversity and opened to colonization converged in species richness and functional or phylogenetic composition while keeping different species composition It becomes increasingly apparent that multiple processes are involved in community assembly.

This model categorizes symptoms of trauma-related psychopathology into (1) those that occur within normal waking consciousness and (2) those that are dissociative and are associated with trauma-related altered states of consciousness (TRASC) along four dimensions: (1) time; (2) thought; (3) body; and (4) emotion. Clinical applications and future research directions relevant to each dimension are discussed. Conceptualizing TRASC across the dimensions of time, thought, body, and emotion has transdiagnostic implications for trauma-related disorders described in both the Diagnostic Statistical Manual and the International Classifications of Diseases. The four-dimensional model provides a framework, guided by existing models of dissociation, for future research examining the phenomenological, neurobiological, and physiological underpinnings of trauma-related dissociation. Putnam notes suAccordingly, this commentary will review the relevance of each of the four dimensions of consciousness to the theoretical, neurobiological, and clinical underpinnings of trauma-related phenomenology in the context of a four-dimensional model (4-D model) outlining a dissociative and a non-dissociative dimension of each of the four dimensions of consciousness those that occur within NWC and (2) those that exhibit a dissociative presentation associated with the experience of TRASC. Experiences of NWC and TRASC can be further classified along four dimensions of consciousness: (1) time (reliving flashbacks [TRASC] versus intrusive memories and reminder distress [NWC]); (2) thought ; (3) body ; and (4) emotion see . It shouThe model makes four predictions: (1) the experience of TRASC will be less common than will be presentations of normal waking consciousness given that states of normal waking consciousness, by definition, are the most common phenomenological state of human beings; (2) TRASC are expected to be less intercorrelated than states of normal waking consciousness as the experience of TRASC is frequently experienced as more \u201ccompartmentalized\u201d; (3) measures of TRASC are expected to be more strongly correlated with other measures of dissociative symptomatology; and (4) experiences of TRASC are predicted to be more specific to an etiology implicating early life adversity and repeated traumatization. Emerging evidence provides support for these predictions in the context of a subjective past and anticipated future. Accordingly, under normal circumstances, time is experienced as continuously moving forward. However, traumatized individuals often relive their traumatic memories through flashbacks and lack the ability to live in the \u201cnow,\u201d reflecting a key dissociative process associated with TRASC. Such reliving events are in contrast to intrusive memory recall most frequently associated with reminder distress and not involving an altered state of consciousness or a dissociative process but rather represent a state of normal waking consciousness traumatized individuals with frequent symptoms of emotional numbing and shutdown and (2) traumatized individuals that solely exhibit general negative affect to identify specific maps of bodily sensations and to explore the relation of these maps to the experience of different emotional experience. These findings will then need to be related not only to the underlying neural deficits of emotion processing but also to treatment outcomes. Moreover, investigating how specific neural networks involved in the consciousness of emotion can be directly targeted through the use of real-time fMRI or EEG-based biofeedback in conjunction with pharmacotherapeutic and psychotherapeutic approaches will be an important avenue for future investigation.In summary, this commentary describes a 4-D model that categorizes symptoms of trauma-related psychopathology into (1) those that occur within normal waking consciousness and (2) those that are dissociative and associated with TRASC along four dimensions of consciousness: (1) time; (2) thought; (3) body; and (4) emotion. Conceptualizing TRASC across these four dimensions has transdiagnostic implications for trauma-spectrum disorders involving dissociation and is relevant to efforts to identify key factors related to the development and maintenance of trauma-related symptoms described both in the DSM and the International Classification of Disease. It will be crucial for future research to examine directly these symptoms along each dimension of consciousness and to identify further their neurobiological and physiological underpinnings, and to determine their role in treatment outcome (also see Sar, Click here for additional data file.Click here for additional data file.Click here for additional data file.Click here for additional data file.Click here for additional data file.Click here for additional data file."} +{"text": "Background. The current study was designed to reveal possible associations between the polymorphisms of the vascular endothelial growth factor (VEGF) gene (rs2010963) and its receptor, kinase insert domain-containing receptor (KDR) gene polymorphism (rs2071559), and markers of carotid atherosclerosis in patients with type 2 diabetes mellitus (T2DM). Patients and Methods. 595 T2DM subjects and 200 control subjects were enrolled. The carotid intima-media thickness (CIMT) and plaque characteristics (presence and structure) were assessed ultrasonographically. Biochemical analyses were performed using standard biochemical methods. Genotyping of VEGF/KDR polymorphisms was performed using KASPar assays. Results. Genotype distributions and allele frequencies of the VEGF/KDR polymorphisms were not statistically significantly different between diabetic patients and controls. In our study, we demonstrated an association between the rs2071559 of KDR and either CIMT or the sum of plaque thickness in subjects with T2DM. We did not, however, demonstrate any association between the tested polymorphism of VEGF (rs2010963) and either CIMT, the sum of plaque thickness, the number of involved segments, hsCRP, the presence of carotid plaques, or the presence of unstable carotid plaques. Conclusions. In the present study, we demonstrated minor effect of the rs2071559 of KDR on markers of carotid atherosclerosis in subjects with T2DM. Type 2 diabetes mellitus (T2DM) is considered a major epidemic of this century. It is estimated that its prevalence will increase worldwide from 371 million people in 2013 to 552 million people in 2030 . The genotype distributions in both patients with T2DM and controls were in Hardy-Weinberg equilibrium for the KDR gene polymorphism [rs2071559: T2DM and controls ]. No statistically significant differences in the VEGF rs2010963 and KDR rs2071559 genotype distribution frequencies were observed between T2DM patients and controls.The genotype distributions in both patients with T2DM and controls were in Hardy-Weinberg equilibrium for both VEGF gene polymorphisms [rs2010963: T2DM between patients with T2DM and controls (32.3% versus 33%). However, the C allele frequency of the KDR rs2071559 polymorphism was significantly lower (p = 0.04) in T2DM subjects as compared to the controls (49% versus 54%).The observed minor allele frequency (MAF) distributions were mostly in agreement with the 1000 Genomes Project data in the European population. The C allele frequency of the VEGF rs2010963 showed no significant difference (Higher VEGF serum levels were demonstrated in subjects with T2DM with the CC genotype (rs2010963) compared to those with other (CG + GG) genotypes . MoreoveThe comparison of atherosclerosis parameters was performed with regard to different genotypes of the VEGF polymorphism rs2010963) upon enrolment. In our study, we did not demonstrate any association between the rs2010963 and either CIMT, the sum of plaque thickness, the number of involved segments, hsCRP or the presence of carotid plaques, or the presence of unstable carotid plaques and CIMT. Variations in the VEGF gene were reported to be weakly associated with CIMT . None ofAdditionally, we also demonstrated an association between the rs2071559 of KDR and the sum of plaque thickness in subjects with T2DM, whereas no association between tested polymorphism of VEGF (rs2010963) and markers of carotid atherosclerosis was demonstrated. The rs2010963 polymorphism of the VEGF gene was not demonstrated to exert a significant influence on the risk of subclinical atherosclerosis manifested by the presence of endothelial dysfunction by brachial artery reactivity and increased CIMT in a series of patients with rheumatoid arthritis . ContrarIn our study, the effect of either rs2071559 of KDR or rs2010963 on VEGF serum levels was demonstrated. These findings are in accordance with our previous studies in which subjects with recent MI history (up to 9 months after MI) were enrolled , 16, 25.In contrast to the minor effect of the rs2071559 of KDR and the absence of the rs2010963 of the VEGF, an association of either rs2071559 or rs2010963 with MI has recently been reported in Caucasians with T2DM , 16, 24.To conclude, in our study we demonstrated a minor effect of the rs2071559 of KDR on markers of carotid atherosclerosis in subjects with T2DM, whereas we failed to demonstrate an effect of tested polymorphism of the VEGF gene (rs2010963) on markers of carotid atherosclerosis."} +{"text": "Actinomycosis is a chronic infection due to anaerobic filamentous bacteria (Actinomyces), which occurs mostly in the cervicofacial region as a chronic granulomatous infection.

We examined their relationship with the first clinical presentation of the 12 most common CVDs in an unselected population-based cohort of men and women.We analysed CArdiovascular disease research using LInked Bespoke studies and Electronic health Records (CALIBER) data, which links primary care and hospital and mortality data in England, from 1997 to 2010. We assembled a cohort of men and women initially free from CVD at baseline and included all patients with PMR and/or GCA (PMR/GCA) diagnosis, matched by age, sex and general practice with up to 10 individuals without PMR/GCA. Random effects Poisson regression analysis was used to study the association between PMR/GCA and the initial presentation of 12 types of CVDs.The analysis included 9776 patients with PMR only, 1164 with GCA only, 627 with PMR and GCA and 105\u2005504 without either condition. During a median of 3.14\u2005years of follow-up 2787 (24.1%) individuals with PMR/GCA and 21\u2005559 (20.4%) without PMR/GCA developed CVDs. Patients with PMR/GCA had lower rates of unheralded coronary death , transient ischaemic attack and coronary and death composite . No associations were observed for other CVDs or cerebrovascular diseases, and in patients with only PMR or GCA. No evidence of interaction by age or sex was found. Estimates decreased with longer PMR/GCA duration and findings were robust to multiple sensitivity analyses.In this large contemporary population-based cohort the presence of PMR and/or GCA was not associated with an increased risk of CVDs or cerebrovascular diseases regardless of PMR/GCA duration. Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are two chronic inflammatory diseases with similar genetic and acute-phase response patterns that affect predominantly women aged \u226550\u2005years.3The inflammatory nature of the two conditions and presence of clinical or subclinical arteritisBecause one in two patients diagnosed with GCA will also develop PMRIn this longitudinal population-based study of individuals registered in primary healthcare practices with linked information to hospital, registry and mortality data, we examine the association between PMR and GCA and the 12 most common clinical initial presentations of CVD. We also assess whether associations differ according to disease duration, sex, age or presence of other autoimmune diseases.All patients with prospectively recorded PMR and/or GCA diagnosis between January 1997 and March 2010 were identified in the CALIBER dataset.13\u201316For each patient with PMR/GCA, up to 10 individuals matched on age (\u00b15\u2005years), sex and practice were randomly selected among those who, on their matched inclusion date, had contacted the medical practice within 1\u2005year and had not been diagnosed with the disease (concurrent sampling). At the start of the observation period all patients were \u226518\u2005years old, free of prior CVD and had been registered with their practice for \u22651\u2005year.Patients with recorded diagnosis of PMR and/or GCA were identified from electronic medical records using Read and ICD-10 codes (see online supplementary table S1). Those with supporting information for PMR or GCA diagnosis or under the care of a rheumatologist within 6\u2005months) were included in primary analyses (see online supplementary figure S1 and table S3). Patients without supporting information for diagnosis were included in sensitivity analyses. Individuals were initially categorised as having PMR and/or GCA (PMR/GCA group) or not having either condition. Because it is uncertain whether the two conditions are different presentations of the same disease, they were then divided into subgroups of those diagnosed only with PMR, only with GCA or with GCA regardless of previous or later PMR diagnosis during follow-up . Patients were further classified into incident and prevalent cases, depending on whether the first recorded diagnosis was made before or after/on study entry.https://www.caliberresearch.org/portal/.Baseline covariates considered were: sociodemographic , cardiovascular , \u22652 prescriptions in the past year , immunosuppressant drug, oestrogen oral contraceptives and hormone replacement therapy), diagnosis with another autoimmune diseases (see online supplementary table S4) and year of study entry. As in previous CALIBER analyses,http://www.caliberresearch.org/portal/.The primary study endpoints were the initial presentation of 12 fatal and non-fatal cardiac and arterial vascular diseases of heterogeneous pathophysiology identified across the four linked data sources in CALIBER: the CPRDFor individuals with PMR/GCA the observation period began on the date on which the patient fulfilled all the study inclusion criteria, or the date of first recorded diagnosis for patients with incident PMR/GCA (see online supplementary figure S2). For individuals without PMR/GCA, it started on the entry date of the matched individual with PMR/GCA. For all patients the study ended on the date of cardiovascular endpoint diagnosis, death, practice deregistration, last practice data collection date or diagnosis of PMR/GCA (for patients who contributed follow-up to both the PMR/GCA and non-PMR/GCA groups).Incidence rates of events per 1000 person-years of follow-up with 95% CIs were calculated in patients with and without PMR/GCA, separately for individuals with prevalent or incident PMR/GCA, and for patients exclusively diagnosed with PMR or GCA. Associations between PMR/GCA and every study endpoint were assessed with random effects Poisson regression accounting for clustering between practices. Missing values of covariates were multiply imputed (see online supplementary text S1). Models were initially adjusted for age and sex, then additionally for cardiovascular factors. To explore possible pathways or mediators of any increase in risk, estimates were further adjusted for: (i) lipid and blood pressure lowering medication; (ii) diagnosis of another autoimmune disease; and (iii) anti-inflammatory and/or immunosuppressant drugs.In secondary analyses: (i) evidence of interactions with sex and age were assessed using Wald tests for interaction; (ii) the relationships with prevalent and incident PMR/GCA were studied; (iii) associations were assessed separately for patients who had only one of the two diseases and for those who had GCA regardless of PMR diagnosis. Furthermore, to examine the association between disease duration and CVD, the follow-up of patients with incident PMR/GCA was split into duration periods . Patients with prevalent disease who had a first diagnosis recorded \u22655\u2005years before study entry were included in the \u22655\u2005year period group. Those with prevalent disease of shorter duration (<5\u2005years) were excluded from this analysis because of uncertainty about exact disease duration.Sensitivity analyses comprised: (i) exclusion of patients with another autoimmune disease; (ii) restriction to patients with \u22656\u2005months of follow-up; and (iii) exclusion of 2\u2005years of follow-up prior to PMR/GCA diagnosis for patients who contributed to the exposed and unexposed groups (to account for delays in diagnosis); (iv) inclusion of patients without supporting information for PMR/GCA diagnosis; (v) exclusion of patients of <50\u2005years of age; (vi) inclusion of first cardiovascular events irrespective of other earlier CVD presentations; (vii) comparison of estimates in the periods before and after the introduction of the pay for performance scheme\u00a0in England ; and (viii) restriction to patients with evidence of active disease (baseline c-reactive protein (CRP) >3.0\u2005mg/mL or elevated erythrocyte sedimentation rate (ESR)).Statistical analyses were done with Stata (V.13.1).Approval was granted by the Independent Scientific Advisory Committee of the Medicines and Healthcare Products Regulatory Agency and the MINAP Academic Group. We registered the protocol at clinicaltrials.gov (NCT02062021).In total 11\u2005567 patients with PMR/GCA and supporting diagnosis information and 105\u2005504 non-PMR/GCA patients free of CVD were identified . Of patiDuring follow-up, 2272 (23.2%) patients with PMR only, 348 (29.9%) with GCA only, 167 (26.6%) with both conditions and 21\u2005559 (20.4%) without either disease experienced one of the 12 CVDs. The incidence of fatal and non-fatal CVDs was slightly lower in patients with than without PMR/GCA , greater differences being observed for heart failure, PAD and stable angina. The small number of CVD events in the subgroup of patients with GCA limited the power to examine differences in rate ratios between patients with PMR and GCA for some CVDs. However, no evidence of increased risk of CVD was observed for those with a higher number of events (see online supplementary table S8) and for composites endpoints .Exclusion of individuals diagnosed with another autoimmune disease or patients aged <50\u2005years, inclusion of patients with >6\u2005months of follow-up and censoring of follow-up 2\u2005years before the diagnosis of PMR/GCA in patients who contributed to both, PMR/GCA and non-PMR/GCA groups, did not alter the results (see online supplementary table S8 and figure S10). Patterns of association remained unchanged when PMR/GCA individuals were included irrespective of whether disease supporting information was recorded (see online supplementary figure S11). Analyses comparing estimates before and after the introduction of the pay-for-performance system of CPRD, those of first presentation of CVD and those restricted to patients with evidence of active disease also showed similar patterns of associations (see online supplementary figures S12 and S13 and table S10).This is to date the largest population-based longitudinal study comparing the initial presentation of a wide range of symptomatic CVDs in patients with and without PMR and/or GCA using contemporary data (1998\u20132010). The large sample size, the longitudinal design and the information available allowed examination of associations in individuals with prevalent and incident PMR/GCA, pure and concomitant PMR and GCA, different duration of disease and adjustment for sociodemographic and cardiovascular factors. In contrast to a previous CALIBER study conducted in the same population in which we reported increased rates of the initial presentation of several CVDs in patients with rheumatoid disease (awaiting publication), no evidence of increased risk of any of the 12 CVD presentations investigated was found in the presence of PMR/GCA.This study has several strengths. The longitudinal population-based design provided evidence of temporality and enabled investigation of associations with duration of PMR/GCA since diagnosis. The large sample size allowed conducting separate analyses for patients with incident and prevalent PMR/GCA and pure and concomitant PMR and GCA, and investigation of sex and age interactions. The time period covered 1997\u20132010) provided epidemiological evidence from a population diagnosed and treated in recent years. The analysis of linked electronic health records spanning primary, hospital and disease registry data improved disease and cardiovascular endpoint ascertainment,10 providStudy limitations include the possibility of PMR/GCA misclassification . In our study, PMR/GCA was defined based on recorded physician diagnosis in primary care and hospitals. Information on American College of Rheumatology classification criteria or histology was not available in the dataset for diagnosis confirmation. However, to reduce the likelihood of PMR/GCA misclassification in patients >60\u2005years of age with incident seronegative rheumatoid arthritis or malignancies,There are several possible explanations for the absence of increased risk of CVD observed in patients with PMR/GCA regardless of disease duration. PMR/GCA affects an old population who might die before a detrimental effect of chronic systemic inflammation on the arteries becomes symptomatic.7Discordance with previous studies that found evidence of increased risk of CVD in patients with PMR/GCA could be related to their inclusion of patients with a history of CVDs and/or primarily diagnosed and treated in tertiary health facilities, and to betterThe chronic inflammatory nature of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) and the presence of clinical or subclinical arteritis might lead to an increased risk of cardiovascular diseases (CVDs). However, findings from the few available studies investigating these associations are heterogeneous and inconsistent.In this large, contemporary longitudinal population-based study of patients treated at primary and hospital levels, we examined the associations between prevalent and incident PMR/GCA and pure and concomitant PMR and GCA, and the 12 most common clinical presentations of CVDs. Regardless of PMR/GCA disease duration, presence of pure or concomitant PMR and GCA was not associated with an increased risk of CVD. No evidence of interaction by sex or age was found.The study findings suggest that, under current clinical practice targeted to patients with PMR and/or GCA, including early and long-term administration of anti-inflammatory and immunosuppressant drugs to control chronic systemic inflammation associated with PMR/GCA, and management of cardiovascular factors with primary prevention, cardiovascular patient risk is similar to the risk of patients without PMR/GCA.In conclusion, regardless of disease duration, diagnosis of pure or concomitant PMR and GCA was not associated with increased risk of CVDs in a large, contemporary population-based sample suggesting that, within the framework of current clinical practice, these diseases do not represent an important risk factor for CVD."} +{"text": "The mechanism by which transmyocardial revascularization (TMR) offers clinical benefit is controversial.

SSI surveillance and process measures evaluation reflecting the intervention have been carried out throughout the study period for about 18 months, based upon a WHO protocol using standardized definitions.Preliminary data show that the crude SSI rate significantly decreased from 9.3% (38/406 patients) before to 5% (18/353) post-intervention. Patients receiving post-operative antibiotics decreased from 50% to 26%; hair removal with shaving decreased from 25% to 2% of patients; theatre discipline improved with a drop in the average number of door openings per operation from 55 to 40.Implementation of a SSI prevention bundle and creation of a safety climate was successfully achieved at AIC Kijabe Hospital with tangible reductions in SSI rates and improvement of process measures. Local production of alcohol-based products for surgical hand and surgical site preparation was an innovative approach to overcome availability and cost barriers. Engagement of senior staff coupled with structured management of patient safety programs helped inculcate these concepts into the local culture and practice and are crucial for the long term sustainability.None declared."} +{"text": "Quantitative MR myocardial strain analysis is typically performed using rectilinear or Cartesian grid tagging, and regional contractility is visually assessed by the deformation of the grid1. However, it is difficult to visually isolate circumferential and radial components of displacement and strain from parallel straight lines on short axis images. This study evaluates the potential of a polar coordinate tagging system2 for quantification of circumferential myocardial displacement in a variety of clinical conditions.33 subjects including 12 patients with congenital heart disease (CHD), 11 with cardiomyopathy (CM) and 10 healthy volunteers (HV) underwent cardiac SSFP cine and myocardial tagging in the mid-ventricular short axis plane with grid tags (line separation 5-7 mm), circular tags (5 mm separation) and radial tags . Visual assessment of circumferential and radial displacement was performed by two observers for each of the six mid short axis segments. Scores were assigned for: overall tag quality , strain , confidence in the findings and ease of interpretation . Quantitative analysis of global and segmental circumferential strain was performed using a semi-automated tool previously described3.Healthy volunteers Figure had the Polar tagging has advantages for the visual and quantitative assessment of myocardial strain. Compared to rectilinear tagging, radial tags are easier to interpret for isolation of circumferential and radial components of myocardial motion.

We also consider sensitivity of findings to the moving time window of analysis . Results show that parks are overwhelmingly at the extreme warm end of historical temperature distributions and this is true for several variables . Precipitation and other moisture patterns are geographically more heterogeneous across parks and show greater variation among variables. Across climate variables, recent inter-annual variation is generally well within the range of variability observed since 1901. Moving window size has a measureable effect on these estimates, but parks with extreme climates also tend to exhibit low sensitivity to the time window of analysis. We highlight particular parks that illustrate different extremes and may facilitate understanding responses of park resources to ongoing climate change. We conclude with discussion of how results relate to anticipated future changes in climate, as well as how they can inform NPS and neighboring land management and planning in a new era of change.US national parks are challenged by climate and other forms of broad-scale environmental change that operate beyond administrative boundaries and in some instances are occurring at especially rapid rates. Here, we evaluate the climate change exposure of 289 natural resource parks administered by the US National Park Service (NPS), and ask which are presently (past 10 to 30 years) experiencing extreme (<5 Recent scientific reviews of the US National Park Service (NPS) suggest the agency needs to manage its parks for changing climatic and ecological baselines in a landscape context Climate change is a principal factor driving the imperative for progressive management aimed at achieving a specified \u2018desired future condition\u2019 (DFC) Recommendations to both scale up and consider changing baselines n\u200a=\u200a289), including a 30 km buffer around each park\u2019s boundary Our analyses were performed for all natural resource parks considered by the NPS Inventory & Monitoring Program\u2019s landscape dynamics monitoring project, NPScape (2 at the Equator and 2000 km2 at 70\u00b0N latitude) for each month \u00d7 year, 1901\u20132012. Although this dataset is spatially coarse, at least relative to the size of some parks , it offers for all NPS geographies the highest spatiotemporal resolution of observed climate over the 20th and 21st centuries. We selected for analysis monthly averages of daily temperature , percentage cloud cover, and vapor pressure (haP), as well as total monthly precipitation (mm) and monthly frequencies of frost days and wet days (rain days per month). We used the monthly climate variables to calculate a series of biologically meaningful variables, including 19 standard bioclimatic variables Gridded climate data were obtained from the Climatic Research Unit (CRU) high-resolution time series version 3.21 (TS 3.21) Although correlations exist among some of these variables, we include the full suite in our analysis because the relevance of individual climate variables can vary dramatically by park resource . As such, the elimination of certain variables due to high statistical correlations would adversely restrict the value of these analyses for park interpretation. Furthermore, the data presented here are percentiles calculated from HRV (see below), not the raw climate variables. Hence, whether variables are correlated is not simply a question of correlation at one point in time; it is a complex question of how sensitive correlations are across the entire 1901\u20132012 period of analysis, interacting with the moving time window of summarization.For each biologically relevant variable, over the entire time series (1901\u20132012), we used three moving windows to calculate a series of running means and standard deviations (SD). Hereafter we refer to these as \u2018moving window means\u2019 and \u2018moving window standard deviations\u2019. These statistical distributions are what we use to estimate HRV. For example, with the 10 year window, we calculated the mean and SD for 103 windows to create the HRV distribution. The three windows were designed to encompass both near- and long-term management and planning considerations, as well as important climatic periods and cycles. In the NPS, many implementation plans have short horizons (<10 years), while strategic plans forecast out 10 to 20 years th percentile for the most recent 10 year moving window of annual mean temperature signifies that the value of this climate variable during this time period was greater than 90% of all annual mean temperature 10 year moving window values). Hereafter we refer to these estimates as \u2018recent percentiles\u2019.For each variable, moving window size, and summary statistic , we calculated the area-weighted mean for each park, based on the spatial intersect of park areas of analysis with the CRU lattice. Using processing logic contained in the NPScape climate grid analysis toolset We then averaged the recent percentiles of the most recent 10, 20, and 30 year moving windows and computed the maximum difference in percentile (max \u0394) among windows; this resulted in \u2013 for each park, variable, and summary statistic \u2013 both an overall measure of recent climate change exposure with respect to HRV, and an estimate of how sensitive that measure was by comparing the different moving window sizes. Note that our measure of variability (moving window SD) does not reveal any information regarding extreme events, such as droughts, heat waves, and storms, which can also impact park resources An example of these steps with annual mean temperature (Bio1) is shown for Grand Canyon National Park . In thisth percentile (low) or greater than the 95th percentile (high), and all intervening percentiles as \u2018average\u2019. We tallied the total number of temperature and precipitation variables that met either of these conditions and categorized each park as extreme low or high on temperature and precipitation if at least one variable in each class was low or high. Parks were considered \u2018mixed\u2019 if they possessed low and high estimates of temperature, or low and high estimates of precipitation. Then, considering only the low and high variables, we calculated the maximum value of their max \u0394\u2019s to provide a maximum estimate of sensitivity to window size. Given the thresholds used to define \u2018extreme\u2019, the maximum possible value for max \u0394 is 15%.Given the number and complexity of variables considered in our analysis, we performed two multivariate analyses in an effort to produce more integrated summaries of recent percentiles. Principal component analyses were used to identify a small set of uncorrelated axes for each combination of summary statistic and measure (mean percentile and max \u0394 percentile). We also conducted a threshold-based classification analysis of mean percentiles, on both the moving window mean and SD, to characterize which parks were extreme on their annual, monthly, or quarterly temperature or precipitation variables. In this classification analysis, as well as in other evaluations of individual climate variables, we define \u2018extreme\u2019 as either less than the 5For a subset of parks spanning the contiguous US, we conducted another sensitivity analysis using local weather station data to examine the degree to which CRU results differ from those obtained using direct climate observations. For local station data, we identified 18 United States Historical Climatology Network stations located within park boundaries that similarly span the 1901\u20132012 period of analysis Lastly, as part of the CRU-based classification analysis, for each climate variable we used a Monte Carlo simulation to test whether the number of extreme parks was significantly different than random expectations. To conduct this test, we first randomly selected 100000 samples of size 289 from a uniform distribution to develop a sampling distribution of the expected number of extreme parks under the null hypothesis . Using that sampling distribution, we then computed the probability of obtaining the observed number of extreme parks for each climate variable.th percentile in 99% of parks), while recent percentiles associated with the annual number of frost days (Frs12) are correspondingly quite low are greater than the 95th percentile), with low sensitivity to moving window size (125 parks (43%) have a maximum difference in percentile that is less than 5%). This general pattern holds for parks from the Pacific Islands to Alaska to the East Coast of the US.Focusing on two common climate variables, annual mean temperature (Bio1) and annual precipitation (Bio12), geographic distributions of recent percentiles are illustrated for moving window means and stanth to 75th percentiles and 233 parks (81%) are within the 5th to 95th percentiles. Hence, only 56 parks (19%) are extreme (<5th percentile or >95th percentile) with respect to annual precipitation.Corresponding results for annual precipitation are rathth to 75th percentiles and 275 parks (95%) are within the 5th to 95th percentiles. Annual precipitation is similar: 188 parks (65%) are within the 25th to 75th percentiles and 277 parks (96%) are within the 5th to 95th percentiles. Hence, only about 10 parks are extreme with respect to either annual mean temperature or annual precipitation, and these parks differ between the two variables triggered by any one of the temperature or precipitation variables, most parks are presently dominated by extreme high temperatures (235 parks (81%) are higher than the 95th percentile), and \u2013 independent of temperature \u2013 some also by either extreme high precipitation (78 parks (27%) are higher than the 95th percentile) or low precipitation (43 parks (15%) are lower than the 5th percentile) .

For resources influenced by climate variables that are presently well within the bounds of HRV, parks might decide that limited funding should be redirected to study other resources that are sensitive to variables approaching the limits of HRV. Parks might also decide to monitor variables with recent extreme percentiles to assess rates of change and detect when and where they become \u2018novel\u2019 with respect to 1901\u20132010 HRV. Beyond applications related to monitoring and management, results offer park interpreters scientific information that may be translated and communicated to the public.Our measures of climate change exposure support broad-scale vulnerability assessments in the NPS, but they also help individual parks understand and interpret which of their major climate drivers are beginning to approach the limits of 1901\u20132012 HRV. Such insights facilitate discussion of how climate change may impact diverse park resources and values , which are often sensitive to different measures of exposure, but they are not intended to replace more detailed analyses required for site-level management and planning within park boundaries. Many parks are in areas of complex topography and indeed this heterogeneity has important implications for climate adaptation In approaching the 100-year anniversary of its creation in 2016, the NPS is poised to enter its next century of natural resource stewardship and science. The new century brings new challenges in terms of stewarding park resources in the face of environmental drivers that operate beyond park boundaries. Climate change further challenges us to develop new, ecologically viable desired conditions to guide the preservation of park resources in this new era of change. While such challenges remain paramount, more integrative research and education in the climate and landscape arenas will contribute to solutions.Appendix S1Mean percentile and maximum difference in percentile (in parentheses) for moving window means: annual mean temperature (Bio1), mean diurnal range (Bio2), isothermality (Bio3), temperature seasonality (Bio4), maximum temperature of the warmest month (Bio5), and minimum temperature of the coldest month (Bio6).(PDF)Click here for additional data file.Appendix S2Mean percentile and maximum difference in percentile (in parentheses) for moving window means: temperature annual range (Bio7), mean temperature of the wettest quarter (Bio8), mean temperature of the driest quarter (Bio9), mean temperature of the warmest quarter (Bio10), and mean temperature of the coldest quarter (Bio11).(PDF)Click here for additional data file.Appendix S3Mean percentile and maximum difference in percentile (in parentheses) for moving window means: annual precipitation (Bio12), precipitation of the wettest month (Bio13), precipitation of the driest month (Bio14), precipitation seasonality (Bio15), precipitation of the wettest quarter (Bio16), precipitation of the driest quarter (Bio17), precipitation of the warmest quarter (Bio18), and precipitation of the coldest quarter (Bio19).(PDF)Click here for additional data file.Appendix S4Mean percentile and maximum difference in percentile (in parentheses) for moving window means: mean annual percentage cloud cover (Cld1), cloud seasonality (Cld4), vapor pressure of the warmest quarter (Vap18), annual number of wet days (Wet12), number of wet days of the warmest quarter (Wet18), and annual number frost days (Frs12).

We also conduct a small meta-analysis of zebrafish orthologs of high confidence neurodevelopmental disorder and neurodegenerative disease genes by looking at duplication rates and relative protein sizes. In the past zebrafish genetic models of these neurodevelopmental disorders and neurodegenerative diseases have provided insight into cellular, circuit and behavioral level mechanisms contributing to these conditions. Moving forward, advances in genetic manipulation, live imaging of neuronal activity and automated high-throughput molecular screening promise to help delineate the mechanistic relationships between different types of neurological conditions and accelerate discovery of therapeutic strategies.Zebrafish are a unique cell to behavior model for studying the basic biology of human inherited neurological conditions.

Under hypoxic conditions (four weeks at 10% O2) mice develop typical symptoms of PH, characterized by an increased muscularization of arterial blood vessels in the lung. The vessel remodeling can be prevented by the chronic application of 5-HT2B receptor antagonists. We found that hypoxic mice also develop increased sensitivity towards the 5-HT2 receptor agonist meta-Chlorophenylpiperazine (mCPP). In contrast to the control group (normoxic mice kept at 20% O2) at low doses of 1 \u00b5g / kg body weight, mCPP triggers plasma protein extravasation (PPE) in the dura mater in hypoxic mice. Dural PPE is a quantifiable indicator of migraine-like events in animal models.The sensitization towards mCPP may coincide with structural remodeling processes in arterial blood vessels of the dura mater, possibly exhibiting similarities to vascular alterations in the lung. A prerequisite in the investigation of vascular alterations in the dura mater is a thorough understanding of the normal organization of dural vasculature in mice and of the extent of its normal biological variance.Histological examinations of the length of dural vessels were performed to quantify and statistically analyze inter- and intraindividual differences.Interindividual differences: The arteriole total lengths are 15% far from the arithmetic mean.Intraindividual differences: The difference in the length of arterioles represents 12% of the total length of the arterioles.On the basis of these results examinations of dural vessel of hypoxic mice can be investigated.No conflict of interest."} +{"text": "Patients with repaired tetralogy of Fallot (TOF) frequently have right bundle branch block.

In some cases , such unusual clustering patterns may be explained by cross contamination or mislabeling of the samples. They also might result from relative proximity of all sampling sites and inadvertent anthropogenic transfer of rodents. Massive population movements that occurred in Sierra Leone during the 1991\u20132002 civil war could contribute to the process of mixing multimammate rat subpopulations carrying different LASV strains most likely originated from the Yawei village area because they cluster closely. A few other human isolates for which no location information is available also clustered with Yawei isolates on the basis of GPC and L sequences, suggesting their origin in the same area. These sequences were obtained in 2002 from United Nations peacekeepers stationed in this part of Sierra Leone (Recent epidemiologic data show that LF was detected in 10 of 13 districts in Sierra Leone, which suggests that the infection is much more common that previously recognized (Molecular characterization of isolates from a wider geographic area of the country is needed to fully understand the diversity of the LASV strains in Sierra Leone and its impact on disease distribution and risk.

These diagnostic tests are extremely relevant to disease surveillance and monitoring and evaluation of interventions to prevent primary LASV infection in humans.

However, knowledge of implementation processes is very limited. To address this limitation, we drew on the Stages of Implementation Completion (SIC) framework to measure a key phase of peer leader implementation.40 high schools were randomly assigned to either immediate Sources of Strength (n = 20) or waitlist (n = 20). The schools were underserved by mental health services and over-represented by youth at high risk for suicide . In the 20 implementing schools, 656 students (18-71 per school) received Peer Leader (PL) training. Adult mentors facilitated PL meetings to reinforce program concepts and help PLs plan and execute activities to spread healthy coping practices. Using a framework derived from the Stages of Implementation Completion (SIC), school reports of PL meeting dates/attendance were codified as indices of school success in retaining and preparing PLs. Surveys with 5,712 students showed wide school-level variation in success of PLs in reaching their classmates with the prevention concepts. In analytic models examining predictors of school-level exposure, a higher proportion of student population trained as PLs and greater retention of PLs predicted higher population exposure to the prevention program, congruent with diffusion of innovations theory, whereas frequency of meetings did not.Identified an efficient method (derived from the SIC) for assessing a school's success in preparing/retaining peer leaders.

Clarifying the detailed mechanism for aortic dissection is of great significance for establishing effective pharmacotherapy for this high mortality disease. In the present study, we evaluated the influence of biomechanical stretch, which mimics an acute rise in blood pressure using an experimental apparatus of stretching loads in vitro, on rat aortic smooth muscle cell (RASMC) death. Then, we examined the effects of azelnidipine and mitogen-activated protein kinase inhibitors on mechanical stretch-induced RASMC death. The major findings of the present study are as follows: (1) cyclic mechanical stretch on RASMC caused cell death in a time-dependent manner up to 4 h; (2) cyclic mechanical stretch on RASMC induced c-Jun N-terminal kinase (JNK) and p38 activation with peaks at 10 min; (3) azelnidipine inhibited RASMC death in a concentration-dependent manner as well as inhibited JNK and p38 activation by mechanical stretch; and (4) SP600125 (a JNK inhibitor) and SB203580 (a p38 inhibitor) protected against stretch-induced RASMC death; (5) Antioxidants, diphenylene iodonium and tempol failed to inhibit stretch-induced RASMC death. On the basis of the above findings, we propose a possible mechanism where an acute rise in blood pressure increases biomechanical stress on the arterial walls, which induces RASMC death, and thus, may lead to aortic dissection. Azelnidipine may be used as a pharmacotherapeutic agent for prevention of aortic dissection independent of its blood pressure lowering effect. With the rapid progress of population aging in most developed countries, the number of patients with atherosclerosis has remarkably increased; this is becoming an extremely serious problem requiring urgent attention It is well recognized that aortic dissection occurs when a small tear generated in the inner aortic wall extends along the wall of the aorta and causes blood to flow between the layers of the tunica media and adventitia of the aorta, forcing the layers apart. Despite the pathophysiological interpretation, the detailed mechanism for aortic dissection still remains unclear. Various efforts have been recently made to clarify the possible reasons for aortic dissection. Collins et al. reported that progressive loss of smooth muscle cells is observed in the specimens of acute aortic dissection characterized by aortic medial degeneration Azelnidipine has been approved for the treatment of patients with hypertension and is extensively used in developed countries In the present study, we used an experimental apparatus of stretching loads in vitro that can simulate sudden increases of blood pressure and observed RASMC death induced by biomechanical stretch. Furthermore, we investigated whether azelnidipine inhibited stretch-induced VSMC death. The effect of azelnidipine on changes in intracellular signaling by biomechanical stretch was also examined to provide a possible mechanism by which azelnidipine may be used as a pharmacotherapeutic agent for the prevention of aortic dissection independent of its blood pressure lowering effect.The study design was approved by an ethics review board of guidelines for the use of laboratory animals of Nara Medical University (No. 11011) and this study conducted in accordance with the guide for the Care and Use of Laboratory Animals as adopted and promulgated by the United States National Institutes of Health.2 in a humidified incubator. RASMCs were used for experiments between the third and sixth passages. The cells were cultured in collagen I-coated (70 \u00b5g/cm2) silicon chambers . When the cell confluency in culture was estimated to be 70\u201380%, the medium was replaced with unsupplemented DMEM. The cells were further cultured for 24 h and then subjected to cyclic mechanical stretch for a given time period using the computer-controlled mechanical Strain Unit . After cyclic stretch, the medium was replaced with DMEM-containing 0.1% FBS. For western blot analysis, a portion of the RASMCs were lysed immediately after stretch stimulation and lysate proteins were collected in the manner described earlier RASMCs were isolated from the thoracic aorta of 8-week-old male Sprague\u2013Dawley rats by enzymatic digestion, as previously described Materials were purchased from Wako (Kyoto) or Nacalai Tesque (Kyoto) unless stated otherwise. Azelnidipine (CS905) was from Daiichi Sankyo, Inc (Osaka). The antibodies used for western blot analyses were as follows: anti-phospho-SAPK/JNK (Thr183/Tyr185) antibody and anti-phospho-p38 MAP kinase (Thr180/Tyr182) antibody were purchased from Cell Signaling Technology, while ECL and ECL plus systems were purchased from GE Healthcare. Collagen I was purchased from Nippon Meat Packers, Inc. (Osaka). All chemical compounds were dissolved in dimethyl sulfoxide (DMSO) at final concentration less than 1% except for special notification.t-test was used to determine significant differences in multiple comparisons. A P value<0.05 was considered to be significant.All experimental values were expressed as mean \u00b1 standard deviation. Analysis of variance along with subsequent Student\u2019s The effect of cyclic mechanical stretch on the viability of RASMCs was firstly examined by measuring MTT reduction and LDH released. The effects of cyclic mechanical stretch on the activation of JNK and p38 (members of MAP kinases family proteins) were assessed by western blot analysis . RASMCs In order to clarify the possible mechanisms of how cyclic mechanical stretch influences cell death, the following two experiments were undertaken.The effects of azelnidipine on cyclic mechanical stretch-induced activation of JNK and p38 in RASMCs were firstly examined and the results are shown in It has been reported that azelnidipine has the effects of anti-inflammation and antioxidant in mouse aneurysmal models The major findings of the present study are as follows: (1) cyclic mechanical stretch of RASMC caused cell death in a time-dependent manner up to 4 h; (2) cyclic mechanical stretch of RASMCs induced JNK and p38 activation with peaks at 10 min; (3) azelnidipine, a calcium channel blocker, inhibited the activation of JNK and p38 by cyclic mechanical stretch in a concentration-dependent manner; and (4) azelnidipine and JNK or p38 inhibitors protected against stretch-induced RASMC death; (5) Antioxidants, DPI and tempol failed to inhibit stretch-induced RASMC death.In this work, we recall the assumption that acute biomechanical stretch applied to cultured VSMCs in vitro simulating a sudden increase in blood pressure resulted in VSMC death that led to aortic dissection. As shown in Azelnidipine is a calcium channel antagonist (blocker) that has been applied extensively to the treatment of patients with hypertension all over the world. In the present study, we found that azelnidipine inhibited RASMC death induced by cyclic mechanical stretch . Under tAmong MAP kinases, JNK and p38 were recognized to be related to cell death or apoptosis We have reported in the previous study that p38 and JNK are oxidative stress sensitive In conclusion, azelnidipine inhibited RASMC death induced by acute cyclic mechanical stretch (originating from a simulated increase in blood pressure in vitro). JNK and p38 in RASMCs were activated by cyclic mechanical stretch; however, the activation was inhibited by azelnidipine. Similar to azelnidipine, pharmacological inhibition of JNK and p38 activation by mechanical stretch suppressed cyclic mechanical stretch-induced RASMC death. It is expected that the mechanism of acute aortic dissection will be clarified from further study of the fate of VSMCs by acute cyclic mechanical stretch. Azelnidipine may be an alternative candidate for prevention of acute aortic dissection independent of its blood pressure lowering effect."} +{"text": "PGR, ABCB1, ABCG2, GSTT1, GSTM1, GSTP1, ATM, TP53 and ATP7B genes.

Studies in both obese humans and murine models of obesity have identified changes in left ventricular (LV) mechanics , which manifest prior to global changes in cardiac function (ejection fraction) and may represent early markers of cardiovascular disease.

We sought to evaluate LV mechanics under inotropic stress conditions with the hypothesis that mechanical deficiencies with obesity would be exacerbated under stress conditions and revealed at earlier stages of disease.C57BL/6J mice were randomized to either a high-fat or control diet for varying time intervals (n=7-10 subjects per group per time point). At each interval, LV mechanics were quantified under baseline (resting) and stress conditions (40 \u00b5g/kg/min continuous infusion of dobutamine) using cine displacement encoding with stimulated echoes (DENSE) on a 7T Bruker ClinScan. Three short-axis and 1-2 long-axis slices were acquired with 11-20 frames per cardiac cycle. Peak strain, systolic strain rates, and torsion were quantified.

A deficit in circumferential peak systolic strain rate at peak stress was the earliest observed marker of obesity-induced ventricular dysfunction.

The study included only patients who underwent mastoid computed tomography and with normal karyotype. We performed a review of its clinical features, giving emphasis to the ear findings.Nine patients were male, the ages ranged from 1 day to 17 years. Ear abnormalities were observed in all patients and involved the external (n=12), middle (n=10) and inner ear (n=3). Microtia was the most frequent finding (n=12). The most common abnormalities of the middle ear were: opacification (n=2), displacement (n=2) and malformation of the ossicular chain. Agenesis of the internal auditory canal (n=2) was the most frequent alteration of the inner ear.Ear abnormalities are variable in patients with OAVS and often there is no correlation between findings in the external, middle and inner ear. The evaluation of these structures is important in the management of individuals with OAVS. Branchial arch disorders comprise several developmental anomalies including the oculo-auriculo-vertebral spectrum (OAVS), also known as Goldenhar's syndrome, or hemifacial microsomy OMIM 164210)2104, 5, The origin of the OAVS is unclear, but it is a complex and heterogeneous condition. Two pathophysiologic mechanisms have been proposed for the OAVS: a reduced blood flow, and focal hemorrhage in the development region of the first and second branchial arches around 30 to 45 days of pregnancy, in the blastogenesis periodAlthough external ear anomalies have been described in OAVS patients - to the point of being inclusion criteria - middle and especially inner ear alterations have received little attention in the literatureThe sample comprised 12 patients with the OAVS seen at the Clinical Genetics Unit, UFCSPA/CHSCPA. The inclusion criteria were alterations in at least two of the following bodily regions: oro-cranial-facial, ocular, auricular, and vertebral, according to Str\u00f6mland et al.'s criteria (2007)p<0.05 were considered statistically significant. The institutional review board approved this study (Opinion no. 581/08 of 25/01/2008).The registries of patients were reviewed to gather clinical data and the results of diagnostic tests . Fisher's exact test (bicaudate) was applied to compare the frequencies were found. The software was the PEPI program. Values of There were 9 male and 3 female subjects. The ages at the first visit ranged from 1 day to 17 years (10 were aged 1 year or less). Most of these patients were referred from the pediatrics unit (n= 7); two others were referred from the plastic surgery unit, one from the cardiology unit, one from the otorhinolaryngology unit, and one from the pediatric surgery unit. Eight subjects had two of the inclusion criteria, three subjects had three, and one had four. All subjects had ear anomalies, affecting the external ear n= 12), the middle ear (n= 8), and the inner ear (n= 3). Microtia was the most frequent finding - it was observed in all cases (ranging from grades I to IV). It was mostly unilateral, to the left, and grade III. Four patients had bilateral microtia (33%). The most common middle ear anomaly was opacification (n= 2), and displaced (n= 2) and malformed ossicular chains (n= 2). Agenesis of the inner ear canal (n= 2) was the most frequent inner ear anomaly. The most common finding in the temporal bone was a non-aerated mastoid (n= 5). Additional alterations in other organs or systems consisted of low height (n=4), craniofacial anomalies (n= 11), ophthalmologic anomalies (n= 2), esophageal/ pulmonary anomalies (n= 6), cardiac anomalies (n= 7), abdominal anomalies (n= 4), skeletal anomalies (n= 6), and cerebral anomalies (n= 5) , the mid.Figure 1External ear malformations in OAVS patients ranged from slightly dysmorphic to absent ears (or anotia - the most severe form of microtia)Because the ossicles of the ear develop from the dorsolateral terminations of the cartilage in the first (Meckel's cartilage) and second (Reichert's cartilage) branchial arches, anomalies of these structures are often found in the OAVS. Anomalies in the stapedial and tympanic tensor muscle suggest that these structures originate from the first and second branchial archesAlthough external middle ear anomalies are well known, inner ear alterations are rarely observed; these anomalies vary widely and range from mild to severePoorly pneumatized mastoid antrumEnlarged cartilaginous portion of the Eustachian tube lumen and absence of the cartilaginous lateral lamina of the Eustachian tubeLengthened mastoid antrumPreauricular appendages and pitsEar anomaliesAtresia/stenosis of the outer ear canalUndeveloped tympanic membraneMicrotia/anotiaIncomplete development of the tympanic cavityImmature and malformed ear ossiclesAbsent oval and round windowAbsence of the tympanic tensor muscleAbnormal path of the facial nerve and absence of the chorda tympani nerveDistorted and hypoplasic cochleaAbsence of the cochlear aqueductImmature vestibular system and absence/fusion of semicircular canalsDisplaced endolymphatic ductWidened vestibular aqueductAbsent/abnormally coursing facial nerve canalSmall, wide, and/or duplicated inner ear canalAgenesis of the inner ear canalDuplicated inner ear canalThe frequency of these anomalies in our sample (25%) was similar to previously reported rates (27% to 36%)As mentioned above, the most frequently reported ear anomalies in the OAVS are external and middle ear abnormalities. Thus, secondary conductive hearing loss predominates in these patientsSurgery is difficult because of the complexity of this condition and the number of factors that may affect the outcome of surgical therapy. On the other hand, hearing loss is generally unilateral in the OAVS; the majority of patients develop speech, and their level of hearing enables them to be socially active. However, patients with bilateral mixed profound hearing loss or pure sensorineural hearing loss required more advanced forms of treatment, such as cochlear implants or bone anchored hearing aidsEar anomalies are frequent and varied in OAVS patients; often there is no correlation among external, middle, and inner ear findings. Therefore, it is important to assess these structures using radiologic methods (such as computed tomography of the mastoid) when managing patients with OAVS."} +{"text": "Autoimmune diseases of central nervous system (CNS) are wide spread in children.

Presenting symptoms consisted of headache in 8 out of 11 (73%), vertigo in 5 (46%), gait abnormalities in 4 (36%), diplopia in 2 (18%) and decreased visual acuity in 1 (9%). Cranial imaging showed obstructive hydrocephalus in 10 (91%) and non-obstructive hydrocephalus in 1 (9%) out of 11, obstruction occurred at the level of the fourth ventricle in 6 out of 10 (60%). Treatment consisted of glucocorticoids in all the patients with additional methotrexate or azathioprine in 6 (55%) and infliximab in 1 (9%) patient. Neurosurgical intervention was performed in 10 out of 11 (91%) patients. Treatment led to remission, improvement or stabilization of disease in 9 out of 10 (90%) of patients. One patient died due to cerebral herniation despite neurosurgical decompression and CSF shunting. Median modified Rankin scale score at last follow-up was 2 (range 0\u20136). A systematic review and meta-analysis of studies on hydrocephalus due to neurosarcoidosis identified 36 patients that compared to our patients had a lower median age at onset and a higher mortality. Acute obstructive hydrocephalus due to neurosarcoidosis is a potentially fatal medical emergency requiring neurosurgical intervention and initiation of immunosuppressive therapy. If patients survive the initial phase, the outcome is generally favorable. Sarcoidosis is an inflammatory disorder that can involve multiple organ systems . InvolveWe retrospectively reviewed all case records from adult patients that were seen between June 2015 until June 2020 at the Neurology Department at the Amsterdam University Medical Centers a tertiary referral center for neurosarcoidosis. We included patients diagnosed with (1) neurosarcoidosis and (2)Detailed history and neurological examination were retrieved from patient files in an electronic database including presenting symptoms, age of onset of symptoms, results of ancillary investigations and data on treatment and treatment response and outcome of hydrocephalus in neurosarcoidosis.A literature search was performed in PubMed using the following terms: (\u201csarcoidosis\u201d [MeSH Terms] OR sarcoid* [tiab] OR \"Neurosarcoidosis\" [Supplementary Concept] OR neurosarcoid* [tiab]) AND . We included articles written in English describing one or more adult patients that were published in the last 25\u00a0years. The search was followed by a manual search in the reference lists of the publications found. The study conforms with the World Medical Association Declaration of Helsinki, 7th revision 2013 Fortaleza. Ethical approval is not required in the Netherlands for a retrospective study with anonymized patient data such as used in our study.Between June 2015 and June 2020, 303 patients were analyzed because of suspected neurological involvement of sarcoidosis at our outpatient department or clinical department. Of these, 153 patients (50%) were diagnosed with neurosarcoidosis had a history of sarcoidosis of which one had a history of neurosarcoidosis-associated myelitis (9%) and three used immunosuppressive therapy at symptom onset. Presenting symptoms were headache in eight (73%), vertigo in five (46%), abnormal gait in four (36%), diplopia in two (18%) and decreased visual acuity in one patient (9%). Time from symptom onset of hydrocephalus-related symptoms to first neurological evaluation was 15\u00a0weeks (interquartile range 3\u201338). Abnormalities on neurological examination included nystagmus and impaired consciousness each in four (36%), papilledema and ataxia each in two (18%) and bilateral sixth nerve palsy in one patient (9%). Neurological examination showed no abnormalities in two patients (18%). Median time from onset of symptoms to diagnosis of neurosarcoidosis was 4 months (range 0\u201334). Other organ systems involved were lymph nodes in four patients (36%), lungs in three (27%) and eyes, liver and bones, respectively, in one patient.Serum angiotensin-converting enzyme (ACE) was analyzed in five patients and was elevated in none of them, soluble Interleukin 2 receptor (sIL-2R) was evaluated in two patients and was elevated in both. Cerebrospinal fluid (CSF) analysis was performed, commonly after external ventricular drain placement, in nine and showed an elevated leukocyte count in eight (89%) patients and elevated total protein in five (56%). One patient had a normal CSF analysis. CSF oligoclonal bands were present in the one patient in which they were tested.Results of cranial imaging were re-evaluated for all patients [ten magnetic resonance imaging (MRI) and one computed tomography (CT)] and showed hydrocephalus in all. The hydrocephalus was non-communicating/obstructive in ten patients and communicating in one. Obstruction was at the level of the fourth ventricle in six patients (60%), the foramen of Monro in three (30%) and the cerebral aqueduct in one 10%). In one patient, there was tonsillar herniation due to the obstruction hydrocephalus was performed in seven patients with no history of sarcoidosis, and showed abnormalities suggestive of sarcoidosis in all of them. Biopsy was performed in all patients. Leptomeningeal biopsy was performed in one patient and showed non-caseating granulomas (definite neurosarcoidosis), lymph node biopsy was performed in eight patients and showed non-caseating granulomas in seven (probable neurosarcoidosis) and was inconclusive in one (possible neurosarcoidosis), in one patient liver biopsy was performed and showed non-caseating granulomas (probable neurosarcoidosis). In the patient with possible neurosarcoidosis, chest CT was highly suggestive of sarcoidosis.Fluor-18-deoxyglucose positron emission tomography (The median follow-up was 23.5\u00a0months (interquartile range 3\u201350\u00a0months). Immunosuppressive treatment was initiated in all 11 patients and consisted of corticosteroid pulse therapy in 7 (64%), corticosteroid maintenance therapy in 9 (82%) and second-line therapy, methotrexate or azathioprine, in 4 patients (36%). Neurosurgical intervention was performed in 10 out of 11 patients (91%) and consisted of external ventricular drain placement followed by ventriculoperitoneal shunt in 3 (30%), ventriculoperitoneal shunt in 5 (50%), ventriculostomy in 3 (30%) and cyst fenestration in 1 patient (10%). All but one patient were treated both with immunosuppressive agents as well as a neurosurgical intervention. Of these ten patients, three underwent neurosurgical intervention prior to immunosuppressive treatment, three received immunosuppressive treatment prior to neurosurgery and in four, neurosurgical and immunosuppressive treatments were initiated simultaneously. Medication was changed during follow-up due to insufficient response to initial therapy, side effects or a relapse of symptoms during follow-up in 5 out of 11 patients (45%). One patient had multiple relapses of symptoms. The relapse of symptoms of neurosarcoidosis was recurrence of hydrocephalus in four (80%) and meningitis without hydrocephalus and myelitis each in one patient (20%). Treatment changes included restarting or increasing the dosage of corticosteroid maintenance therapy in three (80%), corticosteroid pulse therapy in three (60%) and initiation of second-line therapy in five . Third-line therapy (infliximab) was started in one patient (20%). Two patients underwent a second neurosurgical intervention because of failure of CSF shunt or ventriculostomy.Neurological examination at the end of follow-up was available in ten patients and focal neurological deficits were present in only one patient and were attributable to sarcoidosis-associated myelitis. Outcome of neurosarcoidosis at last follow-up was classified as remission in two (18%), improvement in five (45%) and stable disease in three (27%). One patient (9%) died following cerebral herniation as a result of the hydrocephalus. Median modified Rankin scale (mRS) score at last follow-up was 2 (range 0\u20136).Literature review yielded 95 articles of which 46 were assessed for eligibility based on title and abstract.

The 18FDG-PET. These investigations can help ascertain a potential biopsy site outside of the central nervous system. Histopathological evidence of non-caseating granulomas is necessary for a diagnosis of probable or definite neurosarcoidosis [Our study shows that hydrocephalus is a rare but potentially fatal manifestation of neurosarcoidosis that requires a combination of neurosurgical intervention and immunosuppressive treatment. In the absence of a positive history of (neuro)sarcoidosis, the differential diagnosis of acquired hydrocephalus is diverse and includes among others inflammatory, (post-) infectious, (post-)hemorrhagic and (post-)traumatic disorders and intracranial tumors such as colloid cysts or malignancy , 43, 44.coidosis .Presenting symptoms of hydrocephalus in neurosarcoidosis are (sub)acute and related to increased intracranial pressure. Hydrocephalus in neurosarcoidosis is often non-communicating and caused by obstruction of the outflow from the fourth ventricle or of the cerebral aqueduct due to a chronic meningitis. Acute obstructive hydrocephalus can be fatal and an emergency neurosurgical intervention such as CSF shunting, ventriculostomy or decompression should be considered in all patients. Corticosteroid treatment in adjunct to neurosurgical intervention should be strongly considered in all patients. Intensification of immunosuppressive treatment is required in case of a relapse of symptoms, as a persistent or recurring granulomatous chronic meningitis can lead to an additional site of obstruction or shunt failure through obstruction of the CSF shunt . AlthougAs compared to our case series, the mortality was higher (9% versus 22%) and more patients had a diagnosis of definite neurosarcoidosis (10% versus 58%) in the review of the literature. The difference in mortality may be explained by publication bias as multiple articles reported on patients with sudden death. A previous review of the literature found an even higher mortality of 75% in patients with neurosarcoidosis who presented with seizures and had hydrocephalus . HoweverThis study has several limitations. First, patients evaluated were referred to our tertiary center. This may introduce selection bias leading to overestimation of the impact of hydrocephalus in neurosarcoidosis. Second, the retrospective design of our study resulted in heterogeneous assessment of disease activity as well as missing data in some patients. This prohibits drawing firm conclusions regarding outcome and treatment effect. Third, as mentioned above there might be publication bias regarding hydrocephalus in neurosarcoidosis. Nevertheless, our retrospective single-center cohort study and systematic review provides valuable information on a rare disease as hydrocephalus in neurosarcoidosis.In conclusion, hydrocephalus due to neurosarcoidosis is a medical emergency as onset is often (sub)acute and the hydrocephalus is obstructive in nature. Initiation of treatment should be prompt and include both neurosurgical interventions to lower intracranial pressure and immunosuppressive therapy to reduce granulomatous inflammation. If patients survive the initial phase outcome is generally favorable."} +{"text": "Broad-range metagenomic cell-free DNA testing (Karius\u00ae) can identify a variety of pathogens from a single blood sample to help in diagnosis of deep seated and bloodstream infections.

Tofersen is an investigational antisense oligonucleotide designed to reduce synthesis of superoxide dismutase 1 (SOD1) protein through degradation of SOD1 mRNA. Informed by Pre-fALS and the tofersen clinical development program, the ATLAS study (NCT04856982) is designed to evaluate the impact of initiating tofersen in presymptomatic carriers of SOD1 variants associated with high or complete penetrance and rapid disease progression who also have biomarker evidence of disease activity (elevated plasma NfL). The ATLAS study will investigate whether tofersen can delay the emergence of clinically manifest ALS. To our knowledge, ATLAS is the first interventional trial in presymptomatic ALS and has the potential to yield important insights into the design and conduct of presymptomatic trials, identification, and monitoring of at-risk individuals, and future treatment paradigms in ALS.Despite extensive research, amyotrophic lateral sclerosis (ALS) remains a progressive and invariably fatal neurodegenerative disease. Limited knowledge of the underlying causes of ALS has made it difficult to target upstream biological mechanisms of disease, and therapeutic interventions are usually administered relatively late in the course of disease. Genetic forms of ALS offer a unique opportunity for therapeutic development, as genetic associations may reveal potential insights into disease etiology. Genetic ALS may also be amenable to investigating earlier intervention given the possibility of identifying clinically presymptomatic, at-risk individuals with causative genetic variants. There is increasing evidence for a presymptomatic phase of ALS, with biomarker data from the Pre-Symptomatic Familial ALS (The online version contains supplementary material available at 10.1007/s13311-022-01237-4. Despite decades of research, there remains a significant unmet need for effective treatments for amyotrophic lateral sclerosis (ALS). The reasons are manifold, but two key considerations have emerged .

The utility of this critical observation from the Pre-fALS study underscores the importance and value of high-quality natural history data in advancing therapy development for rare diseases [The ATLAS study incorporates unique design elements to evaluate whether presymptomatic initiation of tofersen can delay the emergence of clinically manifest ALS and/or reduce the loss of clinical function over time. ATLAS is the first interventional trial in ALS that uses neurofilament as an enrichment marker for study eligibility and a trigger for initiation of study treatment. The design of ATLAS was built upon the premise that elevations in NfL precede the emergence of clinically manifest ALS, as observed in rapidly progressive diseases .ATLAS has the potential to aid in the identification and understanding of early markers of disease activity beyond NfL. The collection of CSF (at baseline for Part A and prior to every dose in Parts B/C/D) and urine/blood will enable the identification of other potential fluid markers of disease activity. Similarly, comprehensive electromyography (EMG) at screening for Part A and Part B may inform the timing of NfL elevation relative to the emergence of EMG abnormalities and the relative sensitivity of these two biomarkers. Through these biomarker assessments, ATLAS will help to inform the conduct of presymptomatic trials in other subsets of the ALS population.SOD1 variants is continuously evolving due to limited reporting and heterogeneity across carriers. To account for this, an independent Mutation Adjudication Committee was formed to adjudicate eligibility of non-protocol-defined SOD1 variants based on the most up-to-date information at the time. The use of clinically manifest ALS as a primary endpoint is not without challenges, given potential perverse incentive to receive open-label tofersen in Part C; it is for this reason that we have established an independent EAC to confirm the emergence of clinically manifest ALS.A list of variants associated with high/complete penetrance and rapid disease progression was defined in the protocol based on the totality of information ascertained in the literature, genetic databases, and clinical experience. However, characterization of Pre-fALS study, ATLAS aims to take into account two key considerations: (1) when and how participants are informed of their genetic risk, and (2) how participants\u2019 privacy, especially regarding their SOD1 genetic variant and NfL biomarker status, can be protected. For both study sites and participants alike, education, training, and resources are essential to help address these concerns. Specifically, the ATLAS study has implemented genetic testing and counseling processes along with firewalls and strategies to protect participant privacy in the context of a clinical research study.Recognizing the potentially serious and life-long implications of positive genetic testing results on study participants and their families, the study also necessitated the development of a supportive infrastructure to inform, support, and protect prospective participants. Informed by experience from the SOD1 variants associated with high or complete penetrance and rapid disease progression who also have biomarker evidence of disease through elevated plasma NfL. Recognizing that therapeutic intervention in earlier phases of ALS has the potential to yield the greatest clinical benefit, ATLAS, together with data from the VALOR study and its open-label extension study, will inform the optimal timing of treatment initiation in SOD1-ALS. As the first interventional trial in presymptomatic ALS, ATLAS has the potential to yield important insights into the design and conduct of presymptomatic trials, identification, and monitoring of at-risk individuals, and future treatment paradigms in ALS and other neurodegenerative diseases.The ATLAS study (NCT04856982) is designed to evaluate the impact of initiating tofersen in presymptomatic carriers of Supplementary file1 (PDF 536 KB)Supplementary file2 (PDF 589 KB)Supplementary file3 (PDF 545 KB)Supplementary file4 (PDF 599 KB)Supplementary file5 (PDF 535 KB)Supplementary file6 (PDF 616 KB)Supplementary file7 (PDF 553 KB)Supplementary file8 (PDF 580 KB)Supplementary file9 (PDF 553 KB)Supplementary file10 (PDF 629 KB)Supplementary file11 (PDF 563 KB)Supplementary file12 (PDF 563 KB)Supplementary file13 (PDF 619 KB)Supplementary file14 (PDF 598 KB)Supplementary file15 (PDF 600 KB)Supplementary file16 (PDF 571 KB)Supplementary file17 (PDF 545 KB)Supplementary file18 (PDF 625 KB)Supplementary file19 (PDF 562 KB)Supplementary file20 (PDF 527 KB)Supplementary file21 (PDF 527 KB)Supplementary file22 (PDF 607 KB)Supplementary file23 (PDF 329 KB)Below is the link to the electronic supplementary material."} +{"text": "The emotional, behavioral and psychosocial effects of chaotic environments following wars and armed conflicts in terms of exposure to trauma and displacement is well recognized.

Over time this contact results in the development of spontaneous colitis. Muc2-/- n=12 per sex were compared to C57Bl/6 mice for behaviour and tryptophan metabolites across brain, colon and serum. Open Field Test and Light/Dark tests were used to assess anxiety levels, Novel Object and Radial Arm maze were performed to assess memory deficits. Mice underwent one anxiety and one memory test and were euthanized following their last maze. Enzyme-linked immunosorbent assay (ELISA) assessment of 5HT and Kyn were performed on brain, colon and serum samples. T-tests were performed and graphs created using PRISM (v9.4.1).Mucin 2 knockout mice (Muc2-/- mice had decreased anxiety (p=0.0113) compared to C57Bl/6 wild type mice in the light/dark maze. Muc2-/- displayed no significant differences in novel object preferences or the number of memory errors in novel object recognition test and radial arm maze respectively. Serum kynurenine was found to be significantly elevated (p=0.0444) in Muc2-/- mice. The sex factor has to be mentioned here in the results not in the conclusions.Muc2-/-and wild-type mice with depressed anxiety responses and heightened serum kynurenine, however the implications of these findings require further investigation. Understanding how inflammation is driving behavioural alterations can provide pathways to ameliorate the behavioural comorbidities in IBD patients suffering from anxiety of memory deficits.IBD is increasing globally and problems with mental health is often comorbid.

Diagnoses are made by pathologists in Malawi and supported by US pathologists and Malawian clinicians at weekly telepathology conferences. Diagnostic tissue blocks are sent quarterly to UNC for secondary review and further confirmatory studies. Concordance of diagnosis from primary to secondary review was scored as: exact match (level 1), differences in granularity of the diagnosis (level 2), a change in classification but not in treatment (level 3), and a change to the diagnosis that would have altered the treatment course (Major Discordance). Cases with insufficient tissue for review at UNC were excluded from concordance evaluation.Three hundred eighty-eight adult patients were enrolled (June 2013-May 2019). Three hundred twenty-seven tissue blocks were sent to UNC for review and 292 LPDs diagnostic samples had sufficient quality for concordance review. The five most common LPDs were diffuse large B-cell lymphoma , Burkitt lymphoma , classical Hodgkin lymphoma , Multicentric Castleman disease , and low grade non-Hodgkin lymphoma . Level 1, 2 and 3 concordance represented 175 (60%), 49 (17%) and 50 (17%) cases, respectively, and a Major Discordance was identified in 18 cases (6%).With a limited, selected immunohistochemistry panel and telepathology consultation, 94% of cases were accurately classified in real-time, leading to appropriate therapy. The evaluation of concordance provides a measure of quality assurance of the telepathology program, confidence in diagnoses for involvement in interventional trials, and useful data for understanding the epidemiology of LPDs in Malawi."} +{"text": "Osteoporosis is common amongst elderly patient populations and is associated with significant morbidity and mortality. We aimed to assess whether national clinical guidelines regarding the identification, assessment and management of osteoporosis and fragility fracture risk were being adhered to on a female later life psychiatry ward. We then aimed to improve the detection and treatment of osteoporosis amongst this patient cohort and subsequently conducted a re-audit of adherence to relevant clinical guidelines.In July 2021, the electronic health records of the 20 most recently discharged patients from a female later life psychiatry ward were reviewed. The proportion of patients who appropriately received FRAX screening, DEXA scanning and pharmacological management of osteoporosis and fragility fracture risk was recorded. The results were compared to standards identified in national clinical guidelines from the National Institute for Health and Care Excellence (NICE) and the National Osteoporosis Guideline Group (NOGG). In addition, the proportion of patients who had FRAX scores communicated to their general practitioners on discharge was recorded. Recommendations were made based on audit findings, and several changes to ward processes were implemented including incorporating fracture risk scoring in a structured ward round template and displaying information posters about osteoporosis in clinical areas. A re-audit was completed in February 2022 using the same methodology as baseline to re-assess adherence to the audit standards.All included patients were female and aged >65 years, and therefore eligible for consideration of fragility fracture risk according to NICE guidelines. 88% (15/17 patients) of those without pre-existing osteoporosis had FRAX scores calculated during their admission on re-audit compared to 50% (8/16 patients) at baseline. 73% (11/15 patients) had FRAX scores communicated to their GP on discharge at completion of the audit cycle compared to 25% (2/8 patients) at baseline. At completion of the audit cycle 10% (1/10 patients) with intermediate fragility fracture risk received measurement of bone mineral density during admission while 30% (3/10) had this recommended to their GP on discharge. None of the high-risk patients (n = 4) were started on bisphosphonate therapy.On completion of the audit cycle, we found excellent compliance with national guidelines regarding the identification of osteoporosis and fragility fracture risk, which demonstrates the feasibility of considering this aspect of physical health in the setting of a later-life psychiatry ward.

We here demonstrate that an unstable plasmid (pPHDPT3) that encodes a type III secretion system (T3SS) is highly prevalent in Pdp strains from different geographical origins and fish host species. We found that pPHDPT3 undergoes curing upon in vitro cultivation, and this instability constitutes a generalized feature of pPHDPT3-like plasmids in Pdp strains. pPHDPT3 markers were detected in tissues of naturally-infected moribund fish and in the Pdp colonies grown directly from the fish tissues but were undetectable in a fraction of the colonies produced upon the first passage of the primeval colonies on agar plates. Notably, cured strains exhibited a marked reduction in virulence for fish, demonstrating that pPHDPT3 is a major virulence factor of Pdp. The attempts to stabilize pPHDPT3 by insertion of antibiotic resistance markers by allelic exchange caused an even greater reduction in virulence. We hypothesize that the existence of a high pressure to shed pPHDPT3 plasmid in vitro caused the selection of clones with off-target mutations and gene rearrangements during the process of genetic modification. Collectively, these results show that pPHDPT3 constitutes a novel, hitherto unreported virulence factor of Pdp that shows a high instability in vitro and warn that the picture of Pdp virulence genes has been historically underestimated, since the loss of the T3SS and other plasmid-borne genes may have occurred systematically in laboratories for decades.The marine bacterium Photobacterium damselae subsp. piscicida (hereafter dubbed Pdp), a bacterium of the family Vibrionaceae, was first isolated in 1963 from natural populations of white perch (Morone americana) and striped bass (Morone saxatilis) affected by an unknown bacterium in the Chesapeake Bay ) were used.

Many efforts led by WHO, national governments, networks, and academics from the 1990s to the present have tried to turn physical activity into a public health priority. Since its launch in 2015, the Global Observatory for Physical Activity-GoPA! has monitored the progress of national physical activity surveillance, policy and research. The GoPA! Policy Inventory created in 2017, contributes to physical activity policy monitoring and aims to collect data worldwide.In this symposium we will address several key questions about physical activity policy by examining different initiatives such as GAPPA and the experience of monitoring policy globally with the GoPA! policy inventory. We will examine whether it is feasible to track physical activity policy at the global and country levels, if the existence of ?good? physical activity policy is associated with less physical inactivity and how policy indicators may be used for advocacy and guidance in the coming years.Findings show that PA policy monitoring has and still varies substantially by geographic area and country income group. Effectiveness and implementation of PA policies remains challenging worldwide. PA policy indicators can enhance understanding of the links between policy and population levels of PA.GoPA! is committed to continue improving PA policy monitoring for informing and encouraging policy to address physical inactivity worldwide.Agenda and PresentersIntroduction: Michael Pratt (10-minutes)Talk 1: Developing and monitoring physical activity policy: 1990 to today \u2013 Michael Pratt (15-minutes)Talk 2: Instruments for the analysis of national-level physical activity and sedentary behaviour policies: a systematic review \u2013 \u017deljko Pedi\u0161i\u0107 (15-minutes)Talk 3: The GoPA!

Standardized surveillance of neonatal CLABSI enables intra- and interfacility comparisons, which can contribute to quality improvement. To date, there is no national registration system for CLABSI in neonatal care in the Netherlands. Across neonatal intensive care units (NICUs), several different sets of CLABSI criteria and surveillance methods are used for local monitoring of CLABSI incidence rates. To achieve standardized CLABSI surveillance, we conducted a consensus procedure with regard to nationwide neonatal CLABSI surveillance criteria. Method: A modified Delphi consensus procedure for the development of nationwide neonatal CLABSI surveillance criteria was performed between January 2016 and January 2017 in the Netherlands. An expert panel was formed by members of the Working Group on Neonatal Infectious Diseases of the Section of Neonatology of the Dutch Paediatric Society. The consensus procedure consisted of 3 expert panel rounds. Figure Result: The expert panel achieved consensus on Dutch neonatal CLABSI surveillance criteria, which are summarized in Figure 2. Neonatal CLABSI is defined as a bloodstream infection occurring >72 hours after birth, associated with an indwelling central venous or arterial line and laboratory confirmed by 1 or more blood cultures. In addition, the blood culture finding should not be related to an infection at another site and one of the following criteria can be applied: (1) a bacterial or fungal pathogen is identified from 1 or more blood cultures; (2) the patient has clinical symptoms of sepsis and (2A) a common commensal is identified in 2 separate blood cultures or (2B) a common commensal is identified by 1 blood culture and C-reactive protein (CRP) level is >10 mg/L in the first 36 hours following blood culture collection. Conclusion: The newly developed Dutch neonatal CLABSI surveillance criteria are concise, are specific to the neonatal population, and comply with a single blood-culture policy in actual neonatal clinical practice.

The high incidence of metabolic syndrome, cardiovascular disease and diabetes mellitus in this patient group are thought to be major \u2013 and potentially modifiable \u2013 factors contributing to this premature mortality. Therefore, annual monitoring of physical health parameters is recommended by organisations including the Scottish Intercollegiate Guidelines Network (SIGN). The SIGN guideline on schizophrenia advises that the following parameters are checked annually for patients with schizophrenia who are on anti-psychotics: ECG, blood glucose, lipid profile, prolactin, BMI/weight, smoking status and blood pressure. Traditionally, this monitoring is overseen in the community by general practitioners. This audit aimed to capture how the COVID-19 pandemic impacted on the annual physical health monitoring of patients under the care of NHS Borders Community Rehabilitation Team.A retrospective audit was performed by reviewing notes of the 100 patients on the NHS Borders Community Rehabilitation team caseload. Notes from the years of 2019, 2020 and 2021 of all 100 patients on the caseload were reviewed, for documentation of the following seven parameters as recommended by SIGN: ECG, blood glucose, lipid profile, prolactin, BMI/weight, smoking status and blood pressure. Results were then entered manually into a secure spreadsheet. Permission for this audit was granted by NHS Borders.Initial results for the parameters of: ECG, blood glucose, lipid profile and prolactin levels demonstrate that routine monitoring of all four domains has decreased since the start of the COVID-19 pandemic. In 2019 the following numbers of patients had monitoring in these domains: ECG 56 (56%); blood glucose 84 (84%); lipid profile 74 (74%) and prolactin levels 62 (62%).During 2020, the number of patients having monitoring in all four domains fell: ECG 31 (31%); blood glucose (72%); lipid profile 64 (64%) and prolactin levels 48 (48%). During 2021, monitoring levels remained low: ECG 30 (30%); blood glucose 71 (71%); lipid profile 62 (62%) and prolactin levels 43 (43%).Data collection for the parameters of blood pressure, BMI/weight and smoking status is ongoing.Initial results indicate that the COVID-19 pandemic has negatively impacted on the routine physical health monitoring of patients under the care of the community rehabilitation team in NHS Borders.

Milestones were modelled after CanMED roles for each EPA.Of the 15 initial EPAs, nine were recommended for the roundless Delphi panel by the selection committee: (1) identification, diagnosis, and treatment of new onset IBD; (2) assessment and treatment of outpatients with IBD; (3) the endoscopic evaluation of disease activity and the effective communication of endoscopic findings for patients with IBD; (4) provide effective inpatient management and coordinate transition to outpatient care for patients with IBD; (5) recognize and institute preventive health maintenance strategies in patients with IBD; (6) management and treatment of special populations with IBD; (7) identification, diagnosis, and treatment of the various extraintestinal manifestations of IBD; (8) Engage health care systems to improve the quality of care for patients with IBD; (9) engage in scholarly activities related to IBD. Eight of the nine EPAs achieved a consensus score greater than 70%, with the EPA, \u2018engage in scholarly activities related to IBD\u2019 failing to meet this cut-off. Associated milestones were developed for the eight final EPAs.This study was the first attempt to develop a CBME-based IBD curriculum in Canada. With proper funding and guidance, we hope our model can be implemented across Canada in IBD advanced training programs. These methods may also help facilitate the development of CBME curricula for other advanced training programs.NoneNone Declared"} +{"text": "Mediterranean ports are sources of significant economic activity and at the same time they act as recipients of considerable anthropogenic disturbance and pollution. Polluted and low-in-oxygen sediments can negatively impact benthic biodiversity and favour recruitment of opportunistic or invasive species. Macrobenthic communities are an important component of the port biota and can be used as environmental quality indicators. However, a baseline database for benthic biodiversity in Mediterranean ports has not yet been widely established.Mollusca were the most abundant group (34%) in all ports. The highest percentage of opportunistic taxa per station was found before the touristic period in the shipyard of Heraklion port (89.3%).Macrobenthic assemblages were recorded in three Mediterranean touristic ports under the framework of the ENPI CBC MED project MAPMED (MAnagement of Port Areas in the MEDiterranean Sea Basin). Samples were collected from Cagliari , Heraklion and El Kantaoui (Tunisia) ports during February, May and September 2012. The sampling stations were selected according to the different sectors within each port . A total of 277 taxa belonging to 12 phyla were found, of which the 96 taxa were present in all three ports. El Kantaoui port hosted the highest number of macrobenthic taxa.

The Lifestyle Interventions and Independence for Elders (LIFE) Study randomized over 1,500 older adults (aged 70+) to either a physical activity (intervention) or successful aging (control) program with an average of 2.2 years of follow-up. Our analysis used Cox proportional hazards models to evaluate whether elevated depressive symptoms -11 scale with a cutoff score of 16/22 points) moderated the relationship between intervention status and the primary outcome . In a secondary analysis of 1,534 older adults , we confirmed significant main effects of both the physical activity intervention and elevated depressive symptoms on incident major mobility disability but found no evidence of moderation . Results indicate that the benefits of the intervention were comparable between those with and without significant depressive symptoms at baseline, supporting the inclusion of individuals with depression in clinical trials.

It is a well-known occupational respiratory disease in cotton industry workers caused by cotton dust pollution. Many studies have been documented the effects of cotton dust onpulmonary function among workers employed in cotton-spinning mills. However, little data exist on the prevalence of this disorder in female workers particularly in western part of India. The present study was conducted to analyze the effects of exposureto cotton dust on pulmonary functions among female workers. The study was designed to assess the effects of exposure to cotton dust on lung functions among female cotton industry workers. Study group comprises 50 Female workers of cotton industry andcontrol group comprises 50 age matched females who were neither worked in cotton industry nor exposed to cotton dust. Information was collected using standardized questionnaires, physical examination and spirometric measurements. Student's T test was usedto find the difference between spirometric parameters. All the respiratory parameters were reduced in cotton industry workers as compared with control subjects (p<0.0001) and no significant differenceof SpO2 between groups. Cotton dust exposure makes huge impact on respiratory parameters of the cotton industry workers. This deterioration in respiratory health deteriorates with increasing duration of exposure. The health hazards caused by cotton dust shouldbe controlled by creating awareness among the workers & employers. Byssinosis is a crippling occupational lung disease caused by cotton dust. It is a well known occupational respiratory disease among cotton mill workers induced by cotton dust pollution. Byssinosis also called Brown Lung or Brown Lung disease is a typeof Pneumoconiosis caused by dust from cotton fibers. Inhaled dust stimulates histamine release which causes constriction of the air passages, making breathing difficult over time. Inhalation of the dust particles depends on its aerodynamic diameter, surroundingair's velocity, and breathing rate of the person. The inhaled fine cotton dust particles would get sedimented in the gas-exchange part of the lung tissue, where air flow is slow. These fine particles get lodged in the respiratory bronchioles within the centralpart of the acinus. The duration of exposure to cotton dust, type of dust, concentration of dust and the size of dust particle influence the effect on lungs . The preThe present study was conducted in department of physiology, Nootan Medical College & research Centre, Sankalchand Patel University, Visnagar, Mehsana district. This study composed of two groups which contains totally 100 subjects. Group A(Study group) comprises 50 Female workers of cotton industry. The workers were selected from different cotton textile industries of Mehsana district. Group B (control group) comprises 50 age matched females who were neither worked in cotton industrynor exposed to cotton dust. Female subjects of cotton industry, relatives of patients attending various outpatient departments in the age group of 18 - 40 years, who come forward for the study voluntarily and satisfied the inclusion criteria, wererecruited. Subjects on medication for Cardiovascular respiratory illness and Central nervous system (CNS) disorders, subjects with past and present history of CVS disorders, diabetes, psychiatric illness, subjects with history of drug abusing,smoking were excluded.A elaborate clinical history of these volunteers were taken such as relevant past history, family history, drug history, personal history like alcoholism, smoking etc. A structured questionnaire was given to all volunteers (subjects) to obtain the detailsof occupational history and history of past or present respiratory illnesses. The present study was approved by the Institutional ethics committee and an informed consent was taken from all the subjects after explainingthe test procedures and the goal of the study in local language. The anthropometric measurements such as height, weight, Body mass index (BMI), body surface area (BSA), lean body mass (LBM), Fat % were recorded for each subject by using standard procedure[7 - check with author]. SpO2 (Oxygen saturation) was measured with a digital handheld pulse oximeter to investigate oxygen saturation (blood oxygen level) in blood. Participants rested at least15 minutes before examination of SpO2. PFT was done with the help of spirometer (RMS Helios 401). The following variables were evaluated for spirometry: FVC (L) , PEF (L/S) (Peak expiratory flow), FEF 25-75% (Forced expiratory flow),FEV1 (L) (Forced expiratory volume in first second of FVC), MVV (Maximum voluntary ventilation), and FEVI/FVC (%). The subjects were briefed about the procedure of conduction of spirometry and demonstration was given before initiation of procedure. The subjectswere instructed to take deep inspiration from outside and then to expire as forcefully and as fast as she can inside the mouthpiece and recorded the activities. Using all aseptic techniques, the pulmonary function tests were conducted on subjects in standingposition and wearing nose clips. Each test was repeated three times and the best results among the three were considered for analysis. Experiments were done in accordance with revised Helsinki Declaration of 2000.Statistical analysis was performed with SPSS (version 17.0). Results are expressed as mean \u00b1 standard deviation (SD) and assessed using Student's t-test. P-value < 0.05 was considered statistically significant.Table 1(see PDF) describes baseline (anthropometric) characteristics of the subjects. It can be seen that majority of the subjects were adults and all the subjects were females. There was no significant difference between the two groups (control & studygroup) in terms of anthropometric measures. Table 2(see PDF) describes the lung function parameters (Spirometry) of study and control group subjects. All the respiratory parameters were reduced significantlyin cotton industry workers as compared with control subjects (Group B) (p<0.0001). The mean predicted values of FEV1 and FVC parameters were reported in Table 1(see PDF). Predicted value of FEV1 in study subjects were decreased significantly (p<0.0466),predicted FVC value was also decreased in study group however it was not statistically different (p<0.0802). The prevalence of various respiratory symptoms was shown in Table 2(see PDF) and the most common finding was reported is dyspnea followed by chesttightness & cough (16% & 20% respectively). No such symptoms were noted in control group (Group B). Figure 3(see PDF) shows Mean value of SpO2 (Oxygen saturation) in study and control groups. No significant difference of SpO2 between study and controlgroups (p<0.6612). Table 3(see PDF) shows duration of Cotton dust exposure among cotton industry workers. In the present study majority of the subjects had an exposure of at least 10 years or more showing an increased risk of developing lung diseases relatedto byssinosis.Women working in the cotton industry are more susceptible to various health problems much to their counter parts in other sectors. In the present study the anthropometric parameters of study and control group showed no significant difference thus makinggroup comparable. In the present study, Forced vital capacity (FVC) was significantly decreased in cotton industry workers. This is supported by a report of Fishwick and Jadhav A.J et al ,9.StudiThe Present study showed a strong coalition between cotton dust exposure in the cotton industry environment and lung function abnormalities. The pulmonary parameters are decreased significantly in the subjects working in cotton industry. This suggeststhat more aggressive measures must be taken in the workplace and enforcing the use of personal protective equipment, such as respirators and face masks. The health hazards caused by cotton dust should be controlled by creating awareness such as regular healthcheck-ups, personal protective measures and proper ventilation among the employees & employers and thereby ensuring the quality of life of the cotton textile industry workers."} +{"text": "The links between body image disturbances and distorted relationships with parents were supposed since the early conceptualizations of AN by Hilde Bruch.

These pThis topic summarizes ten original research articles that explored the genetic effects and mechanisms of genetic factors contributing to eye development and disease from diverse aspects, providing new insights into treating eye diseases . AccordiInherited eye diseases affect approximately one in 1,000 people worldwide, but the molecular mechanisms underlying most of them remain unclear . IdentifWei et al. identified mitochondrial mutations (OPA1 and LHON-mtDNA) in nearly half of patients with ethambutol-induced optic neuropathy (EON), a well-recognized ocular complication associated with ethambutol treatment in tuberculosis patients. Since some patients with EON have severe and permanent visual loss even without the known risk factors, their findings that mitochondrial genetic variations are major predisposing factors for the development of EON provided a better understanding of EON and additional support for genetic counseling.Zhang et al. found variants in BMP4 contribute to a novel phenotype of pathologic myopia rather than syndromic microphthalmia that have been reported in a previous study , the second leading cause of pediatric lens surgery after congenital cataracts, could be caused by mutations in cbEGF-like domains of fibrillin-1 (FBN1) .

They first reported that the MDM2 SNP309\u00a0G allele was a risk allele for EMM in a Chinese population. Their observation provides new insights into the molecular mechanism underlying these pathologies.Since the experimental studies of many inherited eye disorders in human beings are limited, the availability of genetically engineered animal models is very valuable for exploring the pathogenic mechanisms of these conditions and developing translational therapies.Zhao et al. generated a knock-in mouse model with lanosterol synthase (Lss) G589S mutation, which can recapitulate human congenital cataract resulting from G588S mutation in human LSS. Mice with homozygous Lss G589S mutation exhibited disrupted lens fiber differentiation at early-stage of lens development and down-regulated cholesterol synthesis signaling pathways. Their findings elucidate the important roles of LSS in lens development, contributing to a better understanding of LSS defects and disturbed sterol signaling in cataractogenesis and the development of therapies for cataracts.Hejtmancik et al. generated and characterized the Kcnj13 knockout mouse and RPE-specific conditional Kcnj13 knockout mice.

The study exposure is BMI adjusted weight loss graded into one of five distinct weight loss grades (grades 0\u20134), defined in accordance with the WLGS by combining BMI and percentage weight loss, assessed at two clinical time points: preoperative and at 6 months post-surgery for oesophageal cancer. The study outcome is subjective measures of cancer cachexia one year after surgery, assessed using the cancer-cachexia specific questionnaire EORTC QLQ-CAX24. Multivariable linear regression models calculated mean score differences (MD) with 95% confidence intervals (CI) adjusted for predefined confounders. Statistical significance at Among a total of 232 patients, the highest grade of preoperative WLGS 4 was associated with significantly worse physical decline than lower grades of WLGS 1 and WLGS 2 . Those with preoperative WLGS 2, 3 and 4 reported lower scores on the adequacy of information on weight loss provided to them than those with preoperative WLGS 0. Those with the highest postoperative WLGS 4 had greater eating and weight loss worry than WLGS 2 and WLGS 3 and worse physical decline than WLGS 0 .Higher grades of both preoperative and postoperative WLGS are predictive of cancer cachexia related physical decline one year after surgery for oesophageal cancer. Additionally, preoperative and postoperative WLGS were also predictive of inadequate information concerning weight loss and more worry regarding eating and weight loss, respectively. The WLGS may be an effective risk prediction tool for postoperative cachexia related physical decline in patients undergoing treatment for oesophageal cancer emphasizing its usability in the clinical setting.

For the postoperative WLGS at six months after surgery in addition to the above confounders, type of operation , postoperative complications (Clavien-Dindo score (CDS); low grade (0-II)/high grade (III-IV), enteral and/or parenteral nutrition support for at least 1 week postoperatively (yes/no) was adjusted for.

In total, 253 (58% of eligible) completed the EORTC QLQ-CAX24 questionnaire, and 232 had complete data concerning WLGS before operation and clinical data from medical charts, hence were included in the analysis.Between January 2013 and 15 May 2019, a total of 839 patients underwent surgery for cancer of the oesophagus in Sweden. Of those, 636 patients were alive at the one-year follow-up, 113 were unreachable and one patient was excluded owing to cognitive impairment, leaving a total of 522 patients eligible for inclusion in the OSCAR cohort and 438 eligible for the current study as 84 were included in the cohort before the EORTC QLQ-CAX24 questionnaire was introduced. Among those identified as eligible, 173 (39%) declined to participate for reasons namely, cancer recurrence had a higher comorbidity score than those in the other categories of WLGS 1\u20134 (15.1% to 23.1%). More patients (43.5%) with WLGS 4 had a higher pathological tumour stage (III-IV) than those with the least WLGS 0 (31%). As many as 91.3% of patients in the WLGS 4 received enteral or parenteral nutrition support compared to 77.5% in the WLGS 1 from the five weight loss grades were reported in the eating and weight loss worry dimension MS 30 to 38) and food aversion dimension (MS 28 to 34) [Table 0 to 38 aAmong the dimensions of the QLQ-CAX24 as per the five grades of postoperative WLGS at six months after surgery, the highest MS were reported in the eating and weight loss worry dimension MS 21 to 38) and food aversion dimension (MS 21 to 33) [Table 8 and fooThis population-based prospective cohort study on patients who underwent surgery for oesophageal cancer, exploring if the WLGS is a predictor of long-term cancer cachexia indicated that higher grades of both preoperative and postoperative WLGS are associated with cancer cachexia related physical decline at one year after surgery for oesophageal cancer. Additionally, higher grades of preoperative WLGS were also associated with inadequate information on weight loss aspects of cancer cachexia. Meanwhile, higher grades of postoperative WLGS was also predictive of eating and weight loss worry among patients. The results signify that the WLGS maybe a useful predictor of specific cancer cachexia related decline in oesophageal cancer patients.Several methodological aspects in the present study add to its strength. The population-based nationwide data collection with a longitudinal design minimised selection bias and increased generalisability of the results. The OSCAR cohort is comprised mostly of male patients, which is typical for oeophageal cancer and hence considered representative of the disease demographics and generalisable. Adherence to a strict protocol for data collection further reduced the scope for bias, and another added strength is the unique home-based data collection which reduced missing values. However, selection bias through non-participation of those who were unreachable and declined participation in the study cannot be neglected and may be considered a potential limitation. The choice of the WLGS as the assessment tool for the exposure and EORTC QLQ-CAX24 for the assessment of the outcome is also a strength in the present study. The WLGS has marked a crucial step in redefining clinically important weight loss where BMI is included and has thus been included in the current international clinical practice guidelines for nutrition and cancer . MoreoveIn our study, both the higher grades of preoperative and postoperative WLGS was predictive of physical decline at one year after surgery for oesophageal cancer. In the treatment of patients with oesophageal cancer, resection surgery remains the cornerstone of curatively intended treatment . The surOur results highlight that the WLGS may be a good risk prediction model for the cancer cachexia related physical decline in patients undergoing treatment with oesophageal cancer emphasizing its usability in the clinical setting. The persisting and long-term issues concerning eating and weight status are also a major challenge for health care and the WLGS is a more clinically relevant and robust tool for cachexia related physical decline after surgery for oesophageal cancer.Table S1Table S2"} +{"text": "Night work has been widely studied for the associations with diseases, sickness absence (SA) and disability pension (DP), but less for sustainable working life.

Survey data for two cohorts were utilized to assess night work at baseline (yes/no) in 1998-2003 and 2004-2006, respectively. The final samples for the two cohorts were 34680 and 19637, respectively. Group-based trajectory models were applied.Among those born before 1959 , a five-trajectory solution was best for those with and without night work. The trajectory groups were stable sustainable working life (38-42%), stable unsustainable working life (24-25%), early (13%) or later (13%) decreasing sustainable working life, and between sustainable and unsustainable working life (7%). Among those born after 1958 , four trajectories were detected for those with night work: stable sustainable working life (81%), stable unsustainable working life (6%) and increasing (7%) and decreasing (5%) sustainable working life. For those without nightwork, a three-trajectory solution was best: stable sustainable working life (83%), stable unsustainable working life (6%) and between sustainable and unsustainable working life (11%).Sustainable working life was similar across baseline night work statuses of older cohort but differed in younger cohort.

The diverse small molecules are described according to the date of approval and their syntheses is discussed. This review comprises classical chemical scaffolds together with innovative drugs such as a deuterium-containing drug. The constant research for innovative therapies leads every year to molecules that are approved by the United States Food and Drug Administration (FDA), a federal agency of the U.S. Department of Health and Human Services.Novel building blocks and their connections have been explored much in recent years allowing drug hunters to explore a much bigger chemical space .Small molecule drugs are organic compounds with low molecular weight. For a long time, they have been the backbone of the pharmaceutical industry. There are several benefits that make small molecules important drugs in therapy, such as the possibility of oral administration and cell membrane permeability which allow them to reach specific tissue and targets. For this purpose, small molecule drugs can be designed in order to acquire, for example, specific affinity and selectivity .The goal of this review is to highlight the chemical entities approved in the year 2022 for clinical use.

Four clusters of key sequences were identified: 1) High food and low medical insecurities with private pension plans (43%); 2) Moderate food and low medical insecurities with gradually acquired private pension plans (13%); 3) High food and low medical insecurities with both private and employment-based pension plans (40%); 4) High food insecurity with employment-based pension plans(3%). Regarding the association with depressive symptoms, a group of people who experienced high food and low medical insecurities with private pension plans and those who experienced moderate food and low medical insecurities with gradually acquired private pension plans were more likely to have depressive symptoms compared to those high food and low medical insecurities with both private and employment-based pension plans. These findings highlight the heterogeneity of long-term patterns of financial hardships and patterns of income security, including the limited accessibility for a pension plan through their occupation and that an individual pension plan may not be sufficient to ensure mental health in later life.

Interestingly and contrary to the authors' hypothesis, the analysis revealed no significant association between the AD PRS and multiple measurements in older adults with T2D such as cognitive decline, hippocampal volume, and A\u03b2 burden. Their findings indicate a complex relationship between AD genetic susceptibility and cognitive impairments in T2D.The Lior Greenbaum group reported that global knockout of the mRNA translation factor eukaryotic elongation factor 2 (eEF2) kinase (eEF2K) led to improvement of cognitive function in a mouse model of AD without affecting the brain A\u03b2 pathology.

Such association is not related to leptin levels. Future studies are necessary to illustrate the mechanisms underlying such correlations between brain glucose utilization and body weight.Smith et al.) reported their unexpected findings revealing novel roles of the AD risk gent Abelson interactor family member 3 (Abi3) in metabolism. They found that the Abi3 knockout mice exhibited impaired energy expenditure, increased body weight and body fat, and impaired glucose tolerance and insulin sensitivity.

From January 2010 to February 2020, we identified emergency department visits for 5 conditions that were potentially inappropriately treated using antibiotics per CWC recommendations . We used an interrupted time series design to detect changes in antibiotic prescribing by fitting Autoregressive Integrated Moving Average (ARIMA) models to account for secular trends and seasonality, allowing for change in slopes to measure the effect of each CWC intervention.Antibiotics were commonly prescribed in emergency departments for bronchitis (proportion of visits with antibiotics: 57%) and asthma (22%) in adults; bronchiolitis in children (43%); pharyngitis (39%) and acute otitis media (54%) in adults and children. Based on visual inspection, the proportion of emergency department visits for each condition where antibiotics were dispensed remained relatively consistent. The ARIMA models demonstrated mixed impacts on potentially inappropriate antibiotic prescribing associated with two interruptions: the 2015/2016 CWC recommendations and subsequent 2018 CWC Using Antibiotics Wisely campaign. Following each interruption, antibiotic prescribing was slightly reduced for bronchitis and bronchiolitis (not significant) , but unchanged for asthma and pharyngitis , and slightly increased for acute otitis media (not significant) .Rates of potentially inappropriate antibiotic prescribing remained constant over the past 10 years in Alberta. Campaigns to rethink antibiotic use in emergency medicine may have resulted in small decreases in antibiotic use; however, further initiatives building upon existing campaigns are required to substantially reduce rates of inappropriate antibiotic prescribing."} +{"text": "Children with acute brain damage make up a large group of patients who require multi-stage rehabilitation.

Among characterized NLRs, the broadly conserved ZAR1 NLR is particularly remarkable due to its capacity to recognize at least six distinct families of effectors from at least two bacterial genera. This expanded recognition spectrum is conferred through interactions between ZAR1 and a dynamic network of two families of Receptor-Like Cytoplasmic Kinases (RLCKs): ZED1-Related Kinases (ZRKs) and PBS1-Like Kinases (PBLs). In this review, we survey the history of functional studies on ZAR1, with an emphasis on how the ZAR1-RLCK network functions to trap diverse effectors. We discuss 1) the dynamics of the ZAR1-associated RLCK network; 2) the specificity between ZRKs and PBLs; and 3) the specificity between effectors and the RLCK network. We posit that the shared protein fold of kinases and the switch-like properties of their interactions make them ideal effector sensors, enabling ZAR1 to act as a broad spectrum guardian of host kinases.

The predictive utility of some CCFIs (computed from varying formulation components) for child nutritional status were compared. The purpose of the study was to identify the most suitable among them for possible standardization, validation, and adoption by nutritional health researchers. Using cluster sampling, data from 581 mother\u2013child pairs were collected. Multivariable regression analyses were applied to the data obtained through a community-based analytical cross-sectional survey design. Three of the CCFIs were found to be significantly associated with only wasting (WHZ) from the linear regression models after adjusting for potential confounders and/or correlates. None of the CCFIs was consistently predictive of all three measures of child nutritional status, after controlling for potential confounders and/or correlates, irrespective of the choice of regression method. CCFI 5 was constructed using a dimension reduction technique\u2014namely principal component analysis (PCA)\u2014as the most optimal summary index in terms of predictiveness for child wasting status, validity, and reliability (Cronbach\u2019s \u03b1 = 0.80) that captured relevant dimensions of optimal child food intake. The dimension reduction approach that was used in constructing CCFI 5 is recommended for standardization, validation, and possible adoption for wider applicability across heterogeneous population settings as an optimum CCFI usable for nutritional epidemiological studies among children under five years. Child food intake and/or nutrition-related factors are estimated to be associated with about 45% of global mortality amongst pediatric populations under five years . The seeIYCF indicators are widely utilized within the nutritional epidemiological research (NER) community. They constitute some of the key indicators reported by nutritional epidemiologists, pediatricians, public health nutritionists, and researchers in global, national, regional, and community nutrition study reports. However, NER literature is replete, with study findings of inconsistencies in the predictive utility of the individual IYCF indicators for child nutritional status, contrary to the association theoretically postulated and espoused by the developers and users alike within the NER community ,12,13. FThe purpose of this study was to compare the predictive utility of some CCFIs (computed from varying formulation components) for child nutritional status using a cross-sectional study data set obtained from a resource-constrained study setting in northern Ghana, a West African country in Sub-Saharan Africa (SSA).The northern region of Ghana has the country\u2019s highest prevalence rate of stunting according to the Ghana Demographic and Health Survey 2014 report and the A community-based analytical cross-sectional design was used for this study conducted in June 2018. Together with their children (6\u201323 months), 634 mothers of reproductive age (15\u201349 years) were selected using a two-stage cluster sampling technique from stunting-endemic districts of the northern region of Ghana. There are several languages and dialects spoken in northern Ghana. However, the major languages spoken in the selected study districts are Dagbani (Dagombas), Gonja, and Nanumba. The study participants were drawn from 25 communities across five of the districts in the northern region with a relatively high prevalence of stunting (\u226530%) amongst children under five years of age .n = 284. The required minimum sample size was estimated to be n = 568 based on the assumption of a correction factor of 2.0 due to the design effect for cluster sampling [The final sample size used for the statistical analyses of the study data was 581 and was determined from the standard formula for one-point sample estimation ,44.

The Self-reported dietary intake indicators of child breastfeeding and complementary feeding status and/or practices were used to construct five CCFIs with varying components and scoring guides as summarized in Measures of child nutritional status were the outcome variables in this study. The heights/lengths and weights (anthropometric measurements) of the children and mothers were measured to determine nutritional status. The following measurements were used to calculate the anthropometric (bodily) indicators of underweight, stunting and wasting status, respectively: WAZ (weight-for-age), LAZ (length-for-age), and WLZ (weight-for-length: SD < \u22122) for the children and BMI (body mass index) for the mothers using the WHO Anthro Software Version 3. Computed Z-scores were based on the 2006 WHO growth standards, expressed as standard deviation units from the median value for the WHO growth reference groups .

The majority of children (89.9%) weighed less than 2.5 kg at birth, with 32.2% being stunted .p < 0.05). Of the five CCFIs, the child age group of 9\u201311 months had the highest median score (50th percentile) for CCFI 1, all the three age groups had the same median score for CCFI 2, child age group of 12\u201323 months had the highest median score for CCFI 3, child age group of 9\u201311 months had the highest median score for CCFI 4, and child age group of 12\u201323 months had the highest median score for CCFI 5 , maternal age and height, child age group, usage of insect-treated nets (ITN), and the number of occupants per the child\u2019s household, which were significantly associated with child stunting status in the bivariate analysis. Religion, tribe (ethnicity), marital status, maternal body mass index (BMI), child age group, child gender (sex), child health status (morbidity in the last two weeks and frequency of diarrhea in the last six months), child immunization status, frequency of prenatal care (PNC) services attended, and the source of power (energy) for household utility were significantly associated with child wasting status in the bivariate analysis. The district of residence, community, tribe, type of community , maternal BMI and height, child age group and gender, child health status (morbidity in the last two weeks), the source of power (energy) for household utility, and the number of people per room in the household were significantly associated with child underweight status in the bivariate analysis.

None of the categorical forms of the CCFIs was consistently associated with all the three measures of child nutritional status in the bivariate analyses for both linear and logistic regression model specifications .There was consistency in the predictive outcomes of the categorical forms of the CCFIs irrespective of the choice of regression methods (linear or logistic) used except CCFI 2 for underweight status (bivariate), CCFI 3 for wasting (bivariate) and underweight status (bivariate), CCFI 4 for underweight status (bivariate), and CCFI 5 for wasting (bivariate) and underweight status (bivariate) .There was consistency in the predictive outcomes of the categorical form of the CCFIs for child nutritional status compared with the adjusted (multivariable) and unadjusted (bivariate) models except CCFI 1 for stunting (linear and logistic regression) and underweight status (linear and logistic regression); CCFI 2 for underweight status (linear regression); CCFI 3 for stunting (linear and logistic regression), wasting (linear regression), and underweight status (linear regression); CCFI 4 for stunting status (linear and logistic regression); and CCFI 5 for stunting (linear and logistic regression), wasting (linear regression), and underweight status (linear regression). None of the categorical forms of the CCFIs exhibited Simpson\u2019s paradox .CCFI 1 and CCFI 5 had the lowest and highest Cronbach \u03b1 values, respectively, in correspondence with the number and relevance of the test item components used in their construction . Breastf2) used to assess the trade-off between the goodness of fit and parsimony for the multiple linear regression models explained 6.7% of the variance in child wasting status for CCFI 1, 7.5% for CCFI 4, and 7.5% for CCFI 5 used in the modeling. The adjusted coefficient of determination (adjRr CCFI 5 .The purpose of this study was to compare the predictive utility of CCFIs (computed from varying formulation components) for child nutritional status . After controlling for potential confounders and/or correlates in the regression models, CCFI 5, which was constructed using a dimension reduction statistical technique, namely PCA, was found to have a relatively higher predictive utility for child wasting status compared to CCFI 1, which was constructed following the seminal formula of Ruel and Menon . It was In most of the studies that adopted the Ruel and Menon approachTo the best of our knowledge, no study has adopted the PCA approach to construct CCFI. However, similar epidemiological and public health studies that used dimension reduction as a statistical technique to generate a summary index for predictive modeling purposes found it to be robust and clinically useful ,80,81.Acute undernutrition also referred to as wasting status (WHZ/WLZ) is one of the key nutritional health indicators used in the construction of the Global Food Security Index (GFSI) and Global Hunger Index (GHI) for the classification of populations prone to food insecurity, hunger, and/or malnutrition. The consistency and suitability of the CCFIs especially CCFI 5 for predicting wasting status can also therefore be useful as a public health tool to rapidly identify undernourished children under five years under acute food shortage or emergency situations.The measurement validity of the CCFIs as constructed in this study were generally rated subjectively as ranging between low and very good even though the test items of the sub-domains covered the relevant aspects of optimal child food intake, namely breastfeeding and complementary feeding ,74. CCFIThe Cronbach alpha values of CCFI 1, 4, and 5 were indicative of low to very good internal consistency as a measure of reliability (or homogeneity of the test items) of the construct representing optimal young child food intake ,82,83. TThe findings from the sensitivity analyses and model performance evaluations agree with studies that suggest that the choice of statistical method, form of the predictors in the regression models, and the selection criteria for inclusion or exclusion of one or more IVs in regression models could influence the inferences obtainable ,85. ThisThis study is the first attempt to compare the predictive utility of variously formulated composite child feeding indices (CCFIs) that reflect the multidimensionality of optimal child dietary intake for identifying infants and young children at risk of undernutrition . Even though the cross-sectional design used for this study precludes it from establishing causality, the reliability, validity, model performance, and sensitivity analyses conducted provides additional confidence in the study results. It also highlights some important conditions that potentially debunk or otherwise accentuate the robustness of the postulated association between CCFIs and child nutritional status measures.Some possibly unmeasured confounders and residual confounding coupled with potential reporting bias (under- or overestimation from 24 HDR) and probable covariate selection bias may have suppressed or otherwise potentiated the effects of the CCFIs on child nutritional status ,87. The No internal and external model validation analyses were conducted; thus, the practical utility and generalizability of the CCFIs identified to be predictive of wasting status (WHZ) of children under five years cannot be proffered from this study. No clinical utility or practical epidemiological significance evaluation of the predictive models were conducted because none of the CCFIs was consistently predictive of all the three measures of child nutritional status (undernutrition) in this study after adjusting for potential confounders. No interaction analyses were conducted to assess the moderation effects of covariates such as child age and gender on the association between CCFI and wasting.The predictive utility of CCFIs for child nutritional status is sensitive to the components and/or various measures of child feeding practices used in their formulation and construction. After adjusting for the potential confounders measured, CCFI 1, CCFI 4, and CCFI 5 were significant predictors of wasting status of children under five years.The dimension reduction approach (PCA), which was used in formulating and constructing CCFI 5, is recommended for internal and external validation and possible adoption for wider applicability across heterogeneous study settings as the potentially optimum composite child feeding index usable for nutritional epidemiological studies among children under five years. Just as the hunger index (HI) and global food security index (GFSI) are used for ranking the vulnerability to malnutrition across communities, countries, and geographical regions, CCFI 5 could be used for a similar purpose.More robust study designs and validation methods should be considered for exploration to address some of the limitations widely known to be inherent in cross-sectional design studies and self-reported dietary intake measurement instruments during the validation of these study findings. A comparative study of the effects of the choice of various regression methods on the predictive utility of CCFIs for undernutrition, with or without the dichotomization (or categorization) of continuous data, is also recommended as explored by Sauzet et al. in an ob"} +{"text": "This talk will explore: 1) the conceptual importance of select interpersonal factors inherent to Black culture and bereavement, and 2) the impact of these factors on grief in a Black bereaved sample. 103 Black adults aged 45+ were administered items assessing cultural and bereavement-specific factors. Using linear regressions, closeness (p<.001), suddenness (p=.020), anger (p<.001), and communalism (p<.001) predicted reported levels of grief. This study identifies factors which substantially dictate the experienced levels of grief of bereaved Black adults in the latter half of life. With cultural factors notably impacting the Black bereavement experience, individuals seeking to work with this population must adopt strategies to keep bereaved Black adults connected to their communities throughout their loss. Resources to support Black adults in maintaining healthy continuing bonds with the deceased through abrupt or unsettling losses also appear paramount."} +{"text": "Reminiscence therapy (RT) is a multi-sensory treatment that uses a combination of sight, touch, taste, smell and sound to help persons with dementia (PWD) remember events, people and places from their past lives. Currently, digital technologies such as mobile applications and immersive solutions including virtual and augmented reality, are gaining momentum as supplementary tools for RT. This paper presents a usability study of a web-based and virtual reality application to understand the limitations and opportunities of digital platforms for facilitating engaging experiences for PWD towards recalling memories, while easing the therapy process for the caregivers. A total of ten healthcare caregivers were recruited from the Geriatric Dementia Unit and Geriatric Transitional Unit in Ontario Shores Center for Mental Health Sciences, Ontario Canada. Usability feedback from the caregivers were collected from the interviews after the completion of the System Usability Scale (SUS) questionnaire. Institutional caregivers found both web-based and virtual reality (VRRT) usable with SUS score above average (68/100), but required improvements related to the onboarding training of caregivers. The interview revealed four overarching themes related to the VRRT: (1) Ease of use; (2) Positive impact on caregiving; (3) Potential of reduction in responsive behaviors; (4) Feasibility for promoting social connection during COVID-19 pandemic. Next steps will focus on improving the user experience and expanding the application for immersive VR supporting head-mounted displays, hand tracking, and physiological measures, as well as conducting an usability study with PWD to expand our understanding of using RT digital tools with various levels of immersion."} +{"text": "This case series describes the kinetics of humoral deficiency in patients with relapsed refractory multiple myeloma treated with bispecific antibodies, the infectious complications, and response to COVID-19 immunization.

Despite availability of quality standards, the quality of HIV rapid testing services remains questionable since non-laboratory testers are allowed to conduct testing while they are not specialized in providing testing services.To evaluate the compliance to the quality standards of HIV rapid testing services provided by non-laboratory testers in Makete District, TanzaniaAn explanatory descriptive study employing quantitative approach of data collection was used. An observation of 23 non-laboratory testers performing HIV rapid tests, observation of HIV testing points and documents review was done in 23 testing points to collect data. Data were analyzed using a programmed excel sheet and a three-point scale was used to determine the level of compliance to quality standards.Analysis shows that out of 23 testing points visited, the level of compliance to quality standards was lower for 22 (95.6%) testing points and moderate in 1 (4.4%) testing point. None of the testing point was highly complied to quality standards for HIV rapid testing services.The quality of HIV rapid testing services provided by non-laboratory testers is below the established quality standards for HIV rapid testing services. HIV rapid testing services is among key interventions in the controlling of HIV/AIDS since it provides chances to access HIV care, treatment, prevention, and support services.5Several studies have been conducted to evaluate the quality of HIV rapid testing services. An auditing study conducted in Caribbean and African countries, which involved 968 HIV testing points demonstrated that 20% of the testing points scored level 0; 46% of the testing points scored level 1; 31% of the testing points scored level 2; while 3% of the testing points scored level 3 and none of the testing point that had high level of compliance to quality standards such that none of the testing points scored level 4.6Furthermore a study conducted in 102 private health facilities in Kampala Uganda to evaluate the quality of HIV rapid testing services demonstrated that the quality of HIV rapid testing services is below the recommended quality standards.7Tanzania has also adopted the WHO quality standards for the implementation of HIV rapid testing services.The study was conducted at Makete District Council in Njombe Region, Southern Tanzania. HIV Records for 2016/2017 show that Njombe Region has the highest HIV prevalence (11.4%) in Tanzania.Purposive sampling technique was used to select both public and private health facilities where by all HIV rapid testing points were studied and non-laboratory testers who provided services on the day of the study were observed when performing actual HIV rapid tests.An on-site checklist for document review and observation adopted from WHO by the Tanzania Ministry of Health was used to collect quantitative data. The main areas of observations included: personnel training and certification; physical facility; safety; pretesting phase; testing phase; documentation and records as well as external quality assessment.Ethical clearance to conduct this study was obtained from Research and Ethics Committee (REC) of Muhimbili University of Health and Allied Sciences (MUHAS). Permission to conduct the study was requested from the District Medical Officer of Makete District and officer in charges of the respective health facilities. Study participants were informed about the purpose of the study, procedures, risk and benefits for them to participate in the study. Informed written consent was obtained from each study participant after agreeing to participate in the study.Data were collected manually and entered into excel sheets and they were cleaned and validated. All descriptive data were analyzed using programmed excel sheets and data were presented in frequency tables of numbers, percentages and level of compliance to quality standards for HIV rapid testing service. Summation of each response of the open ended question in each quality standard was used to determine the average compliance for each quality standard. A three-point scae was used to determine the level of compliance to all quality standards for HIV rapid testing services for each testing points whereas testing points scored level 4 (score of 90% or higher) were defined as highly complied to quality standards; level 3 (score of 80% \u2013 89%) were defined as moderately complied to quality standards; level 2 (60% \u2013 79%), level 1 (40% \u2013 59%) and level 0 (less than 40%) were defined as lower complied to quality standards.Most of the HIV testers (34.8%) worked on wards, Reproductive and Child Health section (21.7%) and Care and Treatment Centre (13%). The majority of the testers (52%) were from the district level health facilities while about 22% of them were from dispensaries. Majority of the testers (78%) worked in the government health facilities and the remaining 22% worked in private health facilities. Most of testers were women (78.3%) while 21.7% were men. All testers (100%) had ordinary level of secondary education whereas among them 69.6% testers had certificate level of education and 30.4% had diploma level of education. Only one study participant (4.4%) was clinical officer, 30.4% were enrolled nurses and 34.8% were Medical attendants while 30.4% were assistant nursing officers.Evaluation results show that out of 23 testing points visited, the level of compliance to the quality standard was lower for 22 (95.6%) testing points. Two (2) testing points (8.7%) scored level zero, 13 (56.5%) testing points scored level one and 7 (30.4%) scored level two. The level of compliance to HIV rapid testing quality standards was moderate in 1 (4.4%) testing point. None of the testing point had high level of compliance to the HIV rapid testing quality standards, meaning that no testing point attained level four. Average compliance for each quality standard was also determined by observing how non-laboratory testers and testing points operations comply with such standards. These standards include: personnel training and certification; physical facility, safety, pretesting phase, testing phase, documentation and records as well as external quality assessment. The average compliance to personnel training and certification quality standards was 15% whereas: only 9 (39%) out of 23 non laboratory testers that provided HIV rapid testing services on the day of the study received comprehensive training on HIV rapid testing using the nationally approved curriculum; only 2 (9%) non-laboratory testers were trained on external quality assessment (EQA)/proficiency testing (PT) process; only 5 (22%) non-laboratory testers were trained on safety and waste management procedures and practices. No any non - laboratory tester has been certified or licensed through a national certification program to perform HIV rapid testing services.Average compliance to physical facility quality standards was 65% whereas: 16 (66%) testing points have designated area for providing HIV rapid testing services; 11 (48%) testing points were clean and organized for testing; 22 (96%) of testing points had sufficient lighting; none of the testing points store test kits in temperature-controlled environment and there was no device to monitor temperature in all visited testing points and 18 (78%) testing points had sufficient and secure storage space for test kits and other testing consumables.Average compliance to safety standards was 56% whereas: only 2 (9%) testing points had SOPs to manage spills of blood and other body fluids; only 4 (17%) testing points had SOPs to address accidental exposure to potentially infectious body fluids through a needle stick injury, splash or other sharps injury; all 23 (100%) testing points had personal protective equipment (PPE) and testers properly used PPEs through the testing process; 13 (57%) testing points had hand-washing facilities such as water and liquid soap. Only 6 (26%) testing points handled properly waste materials such as sharps, infectious and non-infectious waste and only 13 (56%) testing points disinfect working area with the appropriate disinfectant such as chlorine.The average compliance to pre testing phase standards was 63% whereas: only 9 (39%) testing points had national guidelines for HIV testing services; all 23 (100%) testing points use national algorithm and approved HIV rapid kits; expired HIV rapid test kits such as uni-gold were available in 9 (39.1%) testing points; only 4 (17%) testing points had a standard process for stock management; only 4 (17%) testing points had posted job aides on client sample collection; 19 (82%) testing points had sufficient supplies for client sample collection and in only 9 (39%) testing points, client's identifiers were recorded in the HIV testing register and on test devices as per national guidelinesThe average compliance for testing phase standards was 53% whereas: only 5 (54%) testing points had SOPs on HIV testing procedures and posted at the testing area; timers were available and used routinely in only 1 (4.3%) testing point; sample collection devices such as capillary tube, loop, disposable and pipettes were used accurately in 22 (95%); testing procedures such as correct use of buffer and reading of results on time were adequately followed in 16 (70%) testing points and positive and negative quality control specimens were routinely used in 13 (57%) testing points. Retest for verification was done in 4 (67%) health facilities out of 6 health facilities visited.Average compliance to documentation and records standards was 92% whereas: 20 (87%) testing points had standardized register for documentation, which contain key elements in the registers such as client demographics, kit names, lot numbers, expiration dates and tester name. The final HIV results were recorded correctly in 16 (70%) testing points; client documents and records were securely kept throughout all phases of the testing process in 22 (95%) testing points.Average compliance to External Quality Assessment was 40% whereas: 11 (48%) testing points were enrolled in Proficiency Testing (PT) program; out of 11 testing points enrolled into PT program, only 4 (36%) testing points implement corrective action in case of unsatisfactory PT results; 21 (91%) testing points received periodic supervisory visit and written supervision report was available in only 1 (5%) testing point.This study has shown that the level of compliance to the quality standards for HIV rapid testing is below the recommended standards. Majority of observed HIV testing points scored level one and none of the testing point was highly complied to quality standards, meaning that no testing points scored level four. The results of this study are similar with the study conducted in Kampala Uganda to assess the quality of HIV counseling and testing services, which demonstrated that the quality of HIV testing services is below the recommended standards.13In this study, the highest average compliance score was seen on documentation and records followed by physical facility that included availability of conducive designated areas for provision of HIV rapid testing services and the lowest average compliance score was seen on personnel training and certification, followed by External Quality Assessment, testing phase, safety and pre testing phase. In addition, this study revealed that availability of new National HIV register that require all key elements to be documented in one register has contributed to improved documentation and record keeping for different data hence results into higher score for documentation and records quality standards. Furthermore, this study shows that most of the non-laboratory testers did not receive comprehensive training to perform HIV rapid testing services and none of them were certified/licensed to perform HIV rapid test through the National Certification Program. This situation has resulted into the lower score for the personnel training and certification quality standards, which was below the recommended quality standards for HIV rapid testing services, which requires that services should be provided by testers who received comprehensive training as well as evaluated for their competence and certified to provide testing services.7In this study we observed low compliance to the quality standards for External Quality Assessment (EQA) and about half of the testing points were enrolled into proficiency testing program and most of the testers were not trained to perform samples for proficiency testing. A study conducted in South Africa to evaluate the quality management system for HIV rapid testing services reported similar findings indicating that the compliance to EQA standards was low and only two clinics out of eleven clinics were enrolled into proficiency testing program. 6In this study, non-adherence to testing procedures including the use of small volume of buffer and non-adherence on time to read result whereby timers were not used during testing were observed. Similar findings were reported in a study conducted in Zambia National Reference Hospital in which the use of inadequate volume of specimen and use of incorrect volume of buffer leading into poor quality of test results was reported.11Our study has shown that a few testing points had guidelines for HIV testing services and Standard Operating Procedures (SOPs). These guidelines and SOPs are important documents for providing guidance and procedures needed to be followed during testing hence lack of guidelines and SOPs compromises the quality of HIV rapid testing services.19Some of the testing points were temporarily closed during data collection period due to lack of trained testers to provide service, and probably such testing points could have useful information regarding the practice of implementation of HIV rapid testing services in studied facilities. Furthermore, due to resource constrains only six facilities were studied, which might have limited the data collected. However, we believe that this study provides valuable insights regarding the quality of HIV rapid testing services provided by non-laboratory testers in the rural setting district in Tanzania.The quality of HIV rapid testing services provided by non-laboratory testers in Makete District is below the established quality standards set for provision of HIV rapid testing services. Most of the non-laboratory testers were not trained, evaluated for their competencies and were not certified or licensed to provide HIV rapid testing services. Some of HIV rapid testing points do not have Guidelines and SOPs that guide provision of HIV rapid testing services, which compromises the quality of HIV testing services. The Ministry of Health and Management of the health facilities should invest more efforts in training and strengthening of certification of non-laboratory testers, increasing enrolment of testing points into proficiency testing and strengthening supervision of testing points in order to improve compliance to quality standards."} +{"text": "Self-isolation regime is an effective measure to contain the pandemic , but the psychological factors predicting compliance with stay-at-home recommendations (CSHR) are understudied.

We requested de-identified, facility-level data from the MA DPH including: number of vaccines ordered by each jail, type of vaccine, and date of the vaccine order from December 2020 - January 2022. We obtained COVID19 vaccines distribution data for the MA general population from the CDC.Vaccine orders were available for 13/14 MA jails. A total of 23,060 vaccines were ordered from the MA DPH between December 2020 - January 2022. January 2021 marked the highest number of vaccine orders by the jails, and all other months were orders < 33% of the January 2021 order. Moderna COVID vaccines were most frequently ordered by the MA jails (88%), followed by Janssen (11%) then Pfizer (1%). In the general population, Pfizer was the most frequently distributed vaccine type (59%), followed by Moderna (37%), then Janssen (4%).Prioritization of jails in MA led to a strong initial push for vaccine distribution which then waned. Potential reasons for the drop in orders include: the initial vaccine orders in January 2021 may have lasted several months, people entering jail after spring 2021 may have received vaccines in the community, and clinical and administrative fatigue may have limited continued robust vaccine protocols. Tracking COVID-19 vaccine orders by jails is a way to assess equitable vaccine operationalization.

The goal of this study is to examine the association between physician (MD) and nurse practitioner (NP) accessibility and practice sensitive outcomes. This project used data from the Translating Research in Elder Care (TREC) longitudinal study and the routinely collected Resident Assessment Instrument \u2013 Minimum Data Set version 2.0 (RAI-MDS 2.0) to test the association between the availability of MDs and NPs in nursing homes (NH) and clinically-relevant resident outcomes of antipsychotic medication (APM) use without indication of psychosis, physical restraint use, hospitalization and emergency department (ED) transfers, and polypharmacy. Eight models were created using logistic regression to test the association between the access measures of daily presence of MD or NP on unit and MDs being involved in care planning and each of the four resident outcomes. The sample consisted of 10,888 residents across 320 units in 92 facilities. Staff from 277 (86%) units reported an MD or NP visited daily and 318 (99%) units reported that the MD or NP could be reached when needed. Following adjustment for multiple confounding variables, there were no associations between either measure of access and any of the resident outcomes. Although we did not find any associations between our measures of access and resident outcomes, additional research which more directly measures physician and NP activities in the NH is required."} +{"text": "Improving the quality and timely access of home health care is a new quality measure and particularly crucial in high-risk ADRD adults following hospitalization. However, a significant portion of older patients waits longer than 2 days to receive home healthcare. In this study, we examine how the quality of home health agency and race are associated with the delay in care among ADRD patients receiving home healthcare and how this delay mitigates the risk of rehospitalization. We find that Black patients in low rated home health agencies have 28% higher odds of delay in care compared to White patients in high rated home health agencies (Odds ratio (95% CI) =1.28 (1.21 - 1.36)). Timely initiation of home health care also reduces the risk of rehospitalization in minority older adults with ADRD."} +{"text": "There is evidence that maternal perinatal depression is associated with adverse neurodevelopmental and mental health outcomes in children.

Sensory perception has been identified as an emerging factor in this process [2]. Sensory vulnerability and atypical sensory experience were identified as risk factors for the development of OCD [3] and a sensory subtype of the disease was proposed in which there is a positive correlation with early onset sensory symptoms, male gender and family background [4]. Adding to the atypical sensory profile, obsessions are frequently experienced as partially perceptual.Our main goals are to characterize the sensory perception in OCD patients; assess the prevalence and intensity of the sensory properties of the obsessive thoughts and explore the how sensory perception, obsessive thoughts and obsessive dimensions/clusters are interrelated.Patients with OCD diagnosis, aged 18 to 65 years and no comorbid mental disorder (except depression) will be recruited. The study battery will include participant form with demographical and clinical features, assessment of depressive and anxiety symptoms (HAM-A and HAM-D) evaluation of clinical outcome measures and obsessive dimensions/clusters and Obsessive Beliefs Questionnaire-44 (OBQ-44)), assessment of sensory perception and sensory properties of obsessive thoughts (Sensory Perception Quotient (SPQ 21) and Sensory Properties of Obsessive Thoughts Questionnaire (SPOQ)).The results will help us understand the interaction between perceptual and cognitive processes in OCD.Better definition of OCD psychopathology and the establishment of a sensory subtype may indicate the need of specific therapeutic indications or a different escalation of treatment measures.No significant relationships."} +{"text": "Tobacco use intersects with the COVID-19 pandemic not only in terms of health consequences, but also on public health systems, economies, and the environment.The global tobacco supply contributes significantly to environmental pollution of the natural ecosystems.

The aspirational goal set by the World Health Assembly in 1988 of eradicating poliomyelitis by 2000 was not achieved.It is thus tempting to consider eradication of poliomyelitis two-thirds complete, with wild poliovirus type 1 in Pakistan and Afghanistan being the final hurdle to finishing the \u2018polio end-game\u2019. But this is sadly not the case. The protracted eradication efforts and perpetually underperforming vaccination programmes using oral live attenuated Sabin poliovirus vaccine (OPV) have birthed calamitous outbreaks of types 1, 2 and 3 circulating vaccine-derived poliovirus (cVDPV) in countries in every World Health Organization region since the first recorded cVDPV outbreak in Haiti in 2020.6 The unprecedented surge in reported confirmed human infections and increasing number of countries with cVDPV detections, either human infections or through environmental surveillance, is cause for great concern to bivalent oral polio vaccine , while introducing at least one dose of inactivated poliovirus vaccine (IPV) for every child, was necessary to reduce the ongoing risk of cVDPV2 outbreaks. Unfortunately the tardy rollout of IPV and outbreak response campaigns using monovalent OPV type 2 have increased the risk of cVDPV outbreaks.We must not bury our heads in the sand.

Dysfunctional emotional processing and regulation play an important role in the development and maintenance of eating disorders (EDs). Difficulties with emotional awareness and regulation in EDs are hypothesized to have their origins in childhood attachment.The study population (N=20) consists of two research groups of patients with AN (group A) and general population controls (group B), matched for gender and age. The age of patients was 12-18 years. All adolescents were female. This study examined the attachment states of mind, assessed by the Adult Attachment Interview (AAI), and emotion regulation difficulties, measured by the Difficulties in Emotion Regulation Scale (DERS).Group A reported significantly higher attachment insecurity (82% vs 50%) than group B. Group A show higher DERS total than group B.Study results show a crucial role of attachment insecurity and emotional dysregulation in the development and maintenance of AN.

From 20In the WHO European Region (EUR), surveillance performance was assessed in the two priority countries of Tajikistan and Uzbekistan. In 2019 and 2020, only Tajikistan met both surveillance indicator targets at the national level. In both years, Uzbekistan met only the stool adequacy indicator target. Subnational surveillance performance was poor in both countries in 2020 ; in UzbeSurveillance performance was assessed in Burma (Myanmar),In the WHO Western Pacific Region (WPR), surveillance performance was assessed in Malaysia and Philippines. Both countries met the NPAFP indicator target in 2019 and 2020, and neither met the stool adequacy indicator in 2019; however, Malaysia did meet the stool adequacy indicator in 2020. During 2019\u20132020, approximately one quarter of Malaysia\u2019s population and <3% of Philippines\u2019 population lived in areas that met both indicator targets ; cVDPV1 Genomic sequence analysis identified 41 cVDPV emergences from AFP cases (39 type 2 cVDPV emergences) in 18 countries in 2019 and 34 cVDPV emergences (32 type 2 cVDPV emergences) in 25 countries in 2020. More than one half (22 of 41) of cVDPV emergences detected in 2019 continued to be detected during 2020.Environmental surveillance is the systematic testing of sewage samples to identify populations shedding polioviruses; environmental surveillance in some locations, might be more sensitive to detection of poliovirus transmission than AFP surveillance, given that paralysis occurs in <1% of poliovirus infections to 599 isolates (57% in Afghanistan) resulting from two 2019 cVDPV2 emergences and seven additional new cVDPV2 emergences in 2020.In 2019, 10 WPV1 genetic clusters (isolates with \u226595% genetic relatedness) were detected in environmental sites from four provinces in Afghanistan and four provinces in Pakistan is an essential component of poliovirus surveillance.

Poliovirus transmission pathways are monitored through sequence analysis of the capsid protein (VP1) coding region from isolates. The accuracy and quality of testing at GPLN laboratories are monitored through an annual accreditation program of on-site reviews and proficiency testing was detected in Afghanistan and Pakistan in 2019 (176 cases) and 2020 (140 cases). Orphan isolates indicate possible gaps in AFP surveillance; in 2019, orphan isolates accounted for five of 176 (3%) WPV1 isolates from AFP patients (two in Afghanistan and three in Pakistan) and in 2020 for 18 of 140 (13%) (11 in Afghanistan and seven in Pakistan).From 2019 to 2020, national NPAFP rates and stool adequacy declined overall in priority countries; subnational surveillance performance declined overall except for WPR countries. Although the total number of WPV1 cases decreased globally from 2019 to 2020, the increase in orphan WPV1 isolates between 2019 and 2020 in both countries suggests gaps in AFP surveillance.

Participants were 65 years or older without dementia, attended at least one primary care visit within 12 months prior to enrollment, and were current users of strong anticholinergics according to the 2012 Anticholinergic Cognitive Burden Scale. Prescribed and over-the-counter medication details were collected during the baseline visit through self-report and included strength, frequency, units/dose and duration. The aTSDD was calculated for each participant assuming continuous use patterns throughout the year. The cTSDD was calculated by summing the aTSDD across the number of years since initiation. Of 66 participants, the median cTSDD was 2425 (IQR 5131), and 48 (72%) exceeded the threshold of dementia risk (>1095). Additionally, the aTSDD had a median of 730 (IQR 547), with 60 (90%) exceeding the threshold of dementia risk while 11 (17%) exceeded dementia risk threshold of 1095 considering 1 year of exposure.

Aim: to summarize the current evidence for diagnosis, treatment, and follow-up of endometrial carcinoma and to provide evidence-based recommendations for clinical practice. Methods: The guidelines have been developed according to standards set by the guideline evaluation tool AGREE II . The strength of scientific evidence has been defined in agreement with The Agency for Health Technology Assessment and Tariff System (AOTMiT) guidelines for scientific evidence classification. The grades of recommendation have been based on the strength of evidence and the level of consensus of the PSGO development group.

OBJECTIVES/GOALS: The goals of this project are to identify genes and gene networks altered by cocaine exposure in neurons (short term), and to use these pathways to understand mechanisms of cocaine neurotoxicity for the establishment of therapeutic targets (long term). METHODS/STUDY POPULATION: To study the molecular effects of cocaine, we generated preliminary proteomics and next-generation RNA sequencing (RNAseq) data from human postmortem prefrontal cortex (Broadmann area 9 or BA9) of 12 cocaine overdose subjects and 17 controls. Future directions for this project include RNAseq analysis of neuronal nuclei sorted from human postmortem BA9 and a human induced pluripotent stem cell-derived neuron (hiPSN) model of cocaine exposure from the same postmortem subjects from whom we have brain samples. RESULTS/ANTICIPATED RESULTS: We found alterations in neuronal synaptic protein levels and gene expression, including the serotonin transporter SLC6A4, and synaptic proteins SNAP25, SYN2, SYNGR3. Pathway analysis of our results revealed alterations in specific pathways involved with neuronal function including voltage-gated calcium channels, and GABA receptor signaling. In the future, we expect to see an enhancement in neuron-specific gene expression signatures in our sorted neuronal nuclei and our hiPSN model of cocaine exposure. The hiPSN model will help elucidate which effects are due to acute versus chronic exposure of cocaine. DISCUSSION/SIGNIFICANCE OF FINDINGS: Transcriptomic signatures found with this analysis can help us understand mechanisms of cocaine neurotoxicity in human neurons. With this work and future proposed studies, we can discover targetable molecular pathways to develop drugs that can reduce or reverse cocaine-related impairment."} +{"text": "Whereas previous studies have investigated life regrets, little attention has been paid to the important accomplishments older adults include in their autobiographic life narratives.

Some Chilean native WEPs have the potential to become new crops and important sources of nutritious and healthy products in the food industry. However, there are still many gaps in knowledge about their nutritional, anti-nutritional and biochemical characteristics; future research is recommended to unveil their properties and potential uses in agriculture and the food industry.Wild Edible Plants (WEPs) still play a vital role in the subsistence of many traditional communities, while they are receiving increasing recognition in tackling food security and nutrition at the international level.

We conducted an extensive literature review by assessing their taxonomic diversity, life forms, consumption and preparation methods, types of use , and nutritional properties. We found that 330 native species were documented as food plants, which represent 7.8% of the total flora of Chile. These species belong to 196 genera and 84 families.

OBJECTIVES/GOALS: Acute respiratory failure (ARF) requiring mechanical ventilation is a frequent complication of sepsis and other disorders. It is associated with high morbidity and mortality. Despite its severity and prevalence, little is known about metabolic and bioenergetic changes that accompanying ARF. METHODS/STUDY POPULATION: In this study, semiquantitative and quantitative ultrahigh performance liquid chromatography mass spectrometry (UHPLC MS) analysis was performed on patient serum collected from the Trial with Acute Respiratory failure patients: evaluation of Global Exercise Therapies (TARGET). Serum from survivors (n=15) and nonsurvivors (n=15) was collected at day 1 and day 3 after admission to the medical intensive care unit as well as at discharge in survivors. Pathway analysis of the biochemical changes was performed to determine whether the disruption in specific metabolic pathways can identify the bioenergetic and metabolomic profile of these patients. RESULTS/ANTICIPATED RESULTS: Significant metabolomic differences were related to biosynthetic intermediates of redox cofactors nicotinamide adenine dinucleotide (NAD) and NAD phosphate (NADP), increased acyl-carnitines, and decreased acyl-glycerophosphocholines in nonsurvivors compared to survivors.

The subjects were asked to determine subjective visual vertical (SVV) for 19 angles of frame tilt (running from -45 degrees to 45 degrees in steps of 5 degrees). The strong VFD of seniors was manifested not only by the increased error in the determination of SVV (SVVE) but also in its distribution. For small and large frame tilt angles, seniors\u2019 SVVE skewness and kurtosis were greater than those of young adults. The SVVE median dependence on frame tilt may be accounted for with a phenomenological model whose two parameters describe the strengths of primary (P) and secondary (S) visual attractors which subjects use to infer SVV: the edges of the frame and its imaginary diagonals. For young adults, these parameters were: PY=14.91 and SY=12.51. For seniors, we observed an over 50% increase in the strength of the primary attractor PS=26.31 while the strength of the secondary one was only weakly affected by aging: SS=13.74.

The Dementia CMC project was a partnership (2013 \u2013 2018) between local Alzheimer\u2019s organizations and ten managed care HPs in California. It used the following model of health care advocacy: 1) Identify dementia-capable best practices to set as systems change indicators; 2) Identify and leverage public policies in support of systems change indicators; 3) Identify and engage champions; 4) Develop and advocate for a value and business case to improve dementia care; 5) Identify gaps in dementia-capable practices; 6) Provide technical assistance, tools, and staff training to address the gaps in dementia-capable practices; and 7) Track systems change. Systems change data was collected through participant observation with HPs and interviews with key informants. HPs reported making systems changes toward more dementia-capable practices such as: better pathways for identification and diagnosis; better identification, assessment, support, and engagement of caregivers; and improved systems of referral to Alzheimer\u2019s organizations. Some indicators of systems change were inconclusive as a result of variability in HP practices and the lack of common record systems between HPs and providers. The application of this advocacy model has led to systems changes that can be replicated to improve care for people living with dementia and their caregivers."} +{"text": "Adequate sleep in hospitalised children is important for a variety of physiological and psychological processes associated with growth, development, and recovery from illness and injury.

These recommendations and the supporting evidence-base are well-described in The second recommendation, concerning collaboration with the bedside carer, was adapted from original recommendations that encouraged family members and visitors to rest at home , we noted that children\u2019s sleep needs differ in quantity by age, generally decreasing from infancy towards puberty sleep during hospitalisation. However, nurses are ideally positioned to capitalise on time spent in hospital to aid children\u2019s sleep through engagement and partnering with families, to promote health and enact their role as patient advocates. The guideline described throughout this article seeks to guide nurses to actively engage in sleep promotion for the hospitalised child. This evidence-based African-centric approach of partnering with families during hospitalisation exemplifies collaborative healthcare and holds the promise of benefits that extend beyond discharge home in resource-constrained contexts."} +{"text": "The dynamic interplay between dementia and psychological trauma can exert powerful effects on nursing home residents\u2019 behavioral symptoms and quality of life. Our objectives in this exploratory study were to assess care aides\u2019 perceptions of how often they worked with residents with past psychological trauma, the types of trauma encountered, and reasons for these beliefs. We conducted semi-structured cognitive interviews (n = 10) with care aides in June 2019 to inform the development of a trauma needs assessment (4 questions) that we included in a large survey of nursing staff (2019 - 2020). Care aides (n = 3761) were sampled from 91 randomly selected urban nursing homes stratified by health region, owner operator model, and size. We completed basic statistics and content analyses. Care aides identified residents they believed to have psychological trauma histories and provided reasons for their beliefs. Approximately 12% of the reported traumatic events were disclosed to staff. The most common, broad categories of trauma to emerge during analysis were abuse (40%) and war exposure (30%). Each had sub-categories. The most common categories of signs of trauma were re-experiencing symptoms such as flashbacks and nightmares (28%), and avoidance of specific triggers, such as water or intimate care (24%). The majority of the reported signs of trauma were persistent and distressing for staff and residents. Some behaviours assumed to be responsive behaviours of dementia may relate to traumatic stress symptomatology.

We report a causal mediation pathway to improvement of stress symptoms in family dementia caregivers with Mentalizing Imagery Therapy (MIT), which employs mindfulness and guided imagery tools to reduce stress and improve understanding of self and others. In a randomized controlled trial of short-term 4-week MIT (N=24) versus a psychosocial support group (N=22), MIT demonstrated superior benefit for reducing perceived stress (p=.006). Increased trait mindfulness was a causal mediator of this effect (p=.02). Neuroimaging pre and post intervention found that increased mindfulness was associated with strengthened connectivity of the dorsolateral prefrontal cortex with an emotion regulation network (p<.001).

Given that those living with others might also be disengaged, the present investigation included eating alone as another source of isolation and examined the impact of the combination of living and eating alone. The proposes of the study were to examine (1) how living and/or eating alone would impact mental distress, (2) whether the impact would be mediated by feelings of loneliness, and (3) if there would be gender differences in the mediation effect. The data were drawn from the Study of Older Korean Americans (SOKA), which surveyed older Korean immigrants in five states during 2017\u22122018. The living/eating arrangement was classified into four-groups: living/eating with others (57%), living with others/eating alone (12.4%), living alone/eating with others (7.3%), and living/eating alone (23.1%). Using the PROCESS macro, we tested the mediation effect of loneliness and the moderation effect of gender in the relationship between the typology and mental distress controlling for background/health characteristics and social capital related variables. Two groups had sociodemographic, health, and social capital disadvantages. Analyses demonstrated that mental distress was linked with living with others/eating alone and living/eating alone, of which relationships were mediated by loneliness only among women. Findings suggest that not only structural isolation but also disengagement with others need to be considered to understand emotional well-being in older immigrant population and gender difference."} +{"text": "QuickDASH for use in assessment of limb function in patients with upper extremity lymphedema using modern psychometric techniques.This study aimed to evaluate and improve the accuracy and efficiency of the QuickDASH, and then fit the data to Samejima\u2019s graded response model (GRM) and assessed the assumption of local independence of items and calibrated the item responses for CAT simulation.We conducted confirmative factor analysis (CFA) and Mokken analysis to examine the assumption of unidimensionality for IRT model on data from 285 patients who completed the QuickDash (r\u2009=\u20090.98).

Thus, we aim to identify the significant genes or biomarkers associated with the stage of endometrial cancer, which may also help reveal the mechanism of EC progression and assess the prognosis of patients with EC.We compared the mRNA expression levels of EC patients with stages I and II as well as stages III and IV in the Cancer Genome Atlas (TCGA) database. The differentially expressed genes (DEGs) of EC patients at different stages were selected by volcano plot and Venn analysis. Gene Ontology (GO) and Pathways were applied to analyze the identified genes. Protein protein interaction (PPI) network was employed to identify the correlation.

Dominguez et al.3 recently brought some negative findings on this topic: (i) the genetic inactivation of receptor-interacting protein kinase (RIPK)1 did not protect against motor neuron degeneration in the superoxide dismutase (SOD)1 model of ALS and (ii) phosphorylated (p)-RIPK1 did not accumulate in the spinal cords of ALS compared to non-ALS patients.

Despite their life-prolonging benefits, uptake of new drugs is often slow among older patients with frailty due to under-representation of frail older adults in pivotal clinical trials and concerns for adverse events. To optimize pharmacotherapy, timely evaluation of the drug benefits and risks is urgently needed. We propose a novel drug monitoring framework that prospectively evaluates the effectiveness and safety of newly marketed drugs for frail and non-frail patients in real-world databases. This framework utilizes a validated claims-based frailty index (CFI) to find early signals for effectiveness and safety of new drugs by updating the analysis at regular intervals as new data become available. In this symposium, we present early results of this prospective monitoring framework for 2 new drug classes using Medicare claims data from the approval date until the end of 2017: 1) angiotensin receptor-neprilysin inhibitor (ARNI) (approved in July 2015) for heart failure with reduced ejection fraction (HFrEF) and 2) sodium-glucose cotransporter-2 inhibitors (SGLT2i) (approved in March 2013) for type 2 diabetes.

In an effort to inform prevention programs, this study seeks to determine the incidence and circumstances of running water in bathing scald burns at our institution.A retrospective review was performed of records from an American Burn Association verified center over a ten year period (1/1/2010 to 12/31/2019). This center treats both children and adults and is affiliated with an academic hospital in a major urban center. The burn database was queried for scald injuries in children less than three years involving bathing. The Child Advocacy and Protective Services team provides inpatient consultation for all children less than three years old with burn injuries allowing us to analyze the specific events surrounding the bathing scald burns in this cohort.A total of 123 patients met inclusion criteria. Three bathing safety risk factors were specifically noted in the chart review: (1) running water, (2) lack of caregiver presence for duration of bathing, and (3) failure of caregiver to check water temperature before bathing. Of the cases identified, 107 (87%) had clear documentation of running water as part of the history of injury, 66 (54%) cases involved failure of caregiver to check the water temperature before bathing and 53 (43%) cases did not have a caretaker present for the duration of the bath. In cases with only one risk factor, running water was identified in 34 (94%) out of 36 cases, and in cases with one or two risk factors, running water remained the primary risk factor with 38 (90%) out of 42 cases. When looking at the combination of risk factors, only three (2%) cases had no risk factors while 77 (63%) involved two or more risk factors.The vast majority of bathing burn injuries in this series involved running water. In addition, a significant number of scald burns occurred from running water alone, even without the other identified risk factors. Conversely, only 2% of scald burns associated with bathing featured none of these three risk factors, suggesting that these injuries could be greatly impacted by safe bathing education."} +{"text": "Genetic networks that regulate meristem transitions were recurrent targets of selection during crop domestication and allow fine-tuning of plant architecture for improved crop productivity. Solanum lycopersicum) and that were recurrent targets of selection during crop domestication and breeding. Fine-tuning the activity of conserved regulators of meristem transitions allows re-balancing vegetative to reproductive growth to customize plant architecture for improved crop productivity.Flowering plants display enormous architectural diversity that mainly results from differences in the position and organization of branches within vegetative and reproductive shoot systems. Where and when branches develop are tightly linked to the onset of flowering, which triggers the release of lateral buds from apical dominance and the outgrowth of additional branches. The transition to flowering depends on the activity of apical meristems, which are small groups of stem cells located at the growing tips of shoots. During vegetative growth, apical meristems produce vegetative organs including leaves and stem until endogenous and environmental signals prompt the transition to reproductive development, which often culminates in the production of an inflorescence, the flower-bearing shoot. It becomes clear that the rate at which meristems transition from the vegetative to the reproductive phase determines the number and pattern of branches in shoots and inflorescences .

The evolution of Solanaceae inflorescence diversity involved changes in the rate of meristem maturation, which are driven by an increased transcriptional divergence of conserved regulatory genes during a critical developmental window that marks the transition to reproductive development that is released in the axil of the last leaf. This process of floral termination and sympodial meristem release is reiterated indeterminately and results in the production of modular structures that consist of a shoot with a terminal flower, resulting in a compound shoot that is characteristic for sympodial plants. In tomato, sympodial growth is recapitulated in inflorescences where each inflorescence meristem releases a sympodial inflorescence meristem at its flank before terminating in a flower, which results in the zig-zag arrangement of flowers on the tomato inflorescence.self-pruning (sp) mutation, which transformed indeterminate tomato vines into determinate bushes with concentrated fruit set that allows mechanical harvesting in large-scale field production and belongs to the CETS gene family (SP encodes an antiflorigen that acts as a repressor of flowering and antagonizes the activity of SINGLE FLOWER TRUSS (SFT), another CETS gene and homolog of Arabidopsis FLOWERING LOCUS T (FT).

The proportion of patients with dual eligibility and the proportion of racial/ethnic minorities were summarized at the HHA level. HHA with higher proportion of dual eligible patients were less likely to have high experience of care rating in professional care delivery , effective communication , and specific direct care issues . HHA with higher proportion of racial/ethnic minorities were also less likely to have high patient experience of care rating across all three domains . Disparities in patient experience of HH care exist and they are associated with low income and racial/ethnic minority status, indicating substantial unmet needs among these socially vulnerable patients."} +{"text": "OBJECTIVES/GOALS: This study\u2019s goal is to examine the feasibility and acceptability of using VRM to impact the APP of adults in the inpatient setting. Aims include examining the: 1) feasibility of VRM for APP management; 2) acceptability of using VRM for APP management; and 3) experience of VRM for APP management. METHODS/STUDY POPULATION: To comprehensively examine participants\u2019 experience of using VRM for APP, this study will employ a convergent mixed-methods design in which living kidney donors (N = 45) will be recruited to serially use VRM during their hospital stay.

OBJECTIVES/GOALS: (1) Identify major biological, psychological, and social determinants of medical and surgical residents\u2019 pain management decisions; (2) Determine salient themes regarding the experience of residents in the management of acute and chronic pain METHODS/STUDY POPULATION: Focus groups of internal medicine and general surgery residents at an academic, tertiary care training hospital located in an urban setting were conducted. Due to the COVID-19 pandemic, all focus groups were conducted virtually and occurred during required didactic sessions to facilitate participation. All interviews were recorded and transcribed. Two reviewers independently reviewed and coded the data following the principles of constructivist grounded theory. RESULTS/ANTICIPATED RESULTS: 42 residents participated in ten focus groups ranging in size from two to five individuals. Six themes emerged demonstrating salient BPS factors in pain management decisions: (1) patient and clinician expectations determine what is considered normal/acceptable; (2) inability of pain scales to reliably capture patient pain; (3) desire for more objective methods of pain assessment, while simultaneously recognizing that pain is an inherently subjective experience; (4) difficulty in determine when pain is 'real\u2019 or 'legitimate'; (5) lack of education and protocols regarding pain management; (6) the importance of engaging other services such as acute pain service or nurse educators in complicated situations. Junior residents often expressed doubt in the appropriateness of their approaches and decisions. DISCUSSION/SIGNIFICANCE OF FINDINGS: Surgical and medical trainees routinely treat pain and may struggle, particularly in the early phases of training, to determine if pain levels are appropriate. There is also a lack of education and/or best practices for assessing and managing pain. These areas represent high-value, clinician-focused targets for future interventions to improve care."} +{"text": "Psychosocial care for residents with serious mental illness (SMI) requires understanding of co-morbidities and careful attention to needs, rights, and preferences.

The experimental pain models have been widely used in acupuncture-analgesia neuroimaging studies with quantitative and controlled advantages. This review aimed to analyze the study design and main findings of acupuncture neuroimaging studies to provide reference for future study. The original studies were collected and screened in English databases and Chinese databases . As a result, a total of 27 articles were included. Heat stimulation and electroacupuncture were the mostly used pain modeling method and acupuncture modality, respectively. The neuroimaging scanning process can be divided into two models and five subtypes. The anterior cingulate cortex and insula were the most commonly reported brain regions involved in acupuncture analgesia with experimental pain models. Acupuncture has been used for alleviating pain in China and other oriental countries for thousands of years. It has been accepted as an alternative or complementary therapy for pain in western countries.

ArticleThe process of the data selection is described in Information including the year of publication, the corresponding author , the trial place, the method of modeling, the acupuncture intervention , the pain assessment, the neuroimaging techniques, and the results of brain regions involved in acupuncture analgesia were extracted.A total of 27 neuroimaging studies with experimental pain models performing on healthy participants were included in this review.The first study was published in 1980 in Chinese. Sixteen of these 27 studies were conducted in China, and 9 studies in the United States. There were 13 corresponding affiliations mentioned; the top two were Massachusetts General Hospital (6 studies) and Peking University (4 studies).The pain modeling methods included heat stimulation (11 studies), electrical stimulation (4 studies), pressure stimulation (3 studies), injections of hypertonic saline (2 studies), potassium iontophoresis stimulation (2 studies), cold pain stimulation (1 study), video stimulation (1 study), tactile stimulation (1 study), stabbing stimulation (1 study), and capsaicin allodynia stimulation (1 study) on healthy participants .Thirteen studies chose manual acupuncture (MA), and 12 studies chose electroacupuncture (EA) as the intervention method. Besides, the transcutaneous electrical nerve (TENS) and transcutaneous electric acupoint stimulation (TEAS) were applied in one study, respectively .Hegu (LI 4) (9 studies), Zusanli (ST 36) (8 studies), and Sanyinjiao (SP 6) (4 studies) were the most frequently used acupoints in these studies .Fifteen studies assessed the pain with the Visual Analogical Scale (VAS), and three studies applied the Gracely Sensory and Affective Scales (GSAS). Other pain assessment scales are shown in Twenty-one studies applied fMRI, two studies used event-related potentials (ERP), two studies used electroencephalogram (EEG), one study used arterial spin labeling (ASL), and one study used both fMRI and PET as neuroimaging techniques .Similar scanning processes were sorted together regardless of the scanning time and repetition times. Scanning processes can be divided into model 1 and model 2 based on whether the pain stimulation was a part of task scanning. Subsequently, according to the sequence of pain stimulation, model 1 was divided into three subtypes [model 1-A .The reported deactivated/activated brain regions are shown in This review mainly described the current status of the central mechanism research of acupuncture analgesia based on the experimental pain model and neuroimaging techniques.Since early 1980, researchers have applied the electrical experimental pain model to investigate the central mechanism of acupuncture analgesia based on the ERP technique (Hegu (LI 4) (9 studies) were theThis review showed that VAS is the preferred scale for assessing pain. Using VAS was previously recommended in both research and clinical practice with the advantages of its simplicity and adaptability was the most used technique of these 27 studies. fMRI indirectly measures brain activity by detecting associated changes in blood flow (hemodynamic response) , affective , and cognitive factors The selection of the types of experimental pain could be broadened but not limited to the neuropathic pain on the skin.

The expanding knowledge and subsequent identification of genetic contributions fosters the understanding of molecular mechanisms leading to disease development and progression. Distinct pathways involved in mitochondrial dysfunction, oxidative stress, and lysosomal function have been identified and open a unique window of opportunity for individualized treatment approaches. These genetic findings have led to an imminent progress towards pathophysiology-targeted clinical trials and potentially disease-modifying treatments in the future.In this review article we will summarize known genetic contributors to the pathophysiology of Parkinson\u2019s disease, the molecular mechanisms leading to disease development, and discuss challenges and opportunities in clinical trial designs.The future success of clinical trials in PD is mainly dependent on reliable biomarker development and extensive genetic testing to identify genetic cases. Whether genotype-dependent stratification of study participants will extend the potential application of new drugs will be one major challenge in conceptualizing clinical trials. However, the latest developments in genotype-driven treatments will pave the road to individualized pathophysiology-based therapies in the future. Parkinson\u2019s disease (PD) is an age-related neurodegenerative disorder characterized by the progressive degeneration of nigrostriatal dopaminergic neurons and extranigral brain regions due to the accumulation of certain \u03b1-synuclein species , LRRK2 (Leucine Rich Repeat Kinase 2), and VPS35 (VPS35 Retromer Complex Component) cause an autosomal dominant form of mPD whereas mutations in PRKN (Parkin), PINK1 (PTEN-induced kinase 1), and PARK7 (oncogene DJ-1) (among others) are associated with autosomal-recessive mPD gene are an unequivocal and frequent risk factor for the development of PD and a promising future drug target.PD is caused by complex interactions between genetic and environmental factors. Mutations in mPD Lill . Althoug Cookson . The ideGBA converge to distinct molecular mechanisms and can be divided into (i) \u03b1-synuclein aggregation resulting in the formation of Lewy bodies has already been proven useful in in-vitro, rodent, and primate models against GBA gene encodes the protein glucocerebrosidase (GCase), a lysosomal hydrolase, which converts glucosylceramide to ceramide and glucose . Interestingly, GD patients have a higher incidence of parkinsonism, and heterozygous mutations in the GBA gene increase the risk of developing PD and \u2018PD risk factor\u2019 GBA variants, which show an association with PD risk but are not considered causative for GD are comparable with IPD whereas carriers of severe GBA variants (sGBA-PD) have a clearly increased risk of dementia with an earlier onset and a more rapid cognitive decline substrate reduction (as often considered for the treatment of GD), (ii) external GCase augmentation, and (iii) the enhancement of GCase activity . Substrate reduction can be achieved by different mechanisms: Glucosylceramide synthase inhibitors decrease glycosphingolipid levels and are used to treat the hematological and visceral presentations of GD patients. The clinical trial GZ/SAR402671 (NCT02906020) showed that the glucosylceramide synthase inhibitor venglustat sufficiently crossed the blood brain barrier (BBB) in humans and R15-006 (NCT02914366) tested the safety, efficacy, and tolerability of ambroxol in PD phenotype, but show a relatively mild cognitive and motor decline during the overall disease course with an increase of LRRK2 kinase activity. The LRRK2 protein has a complex multidomain structure and belongs to the family of protein kinases, which play a fundamental role in the control and regulation of complex cellular processes by transferring phosphate groups to target proteins. The kinase domain of LRRK2 shares similarities with mitogen-activated protein (MAP) kinases, which play a central role in mediating cellular stress. Even though the precise mechanism of LRRK2 is poorly understood, the disease-causing GOF mutations allows heuristic treatments by inhibition of its activity. Currently, two main strategies exist for LRRK2-targeted treatment strategies: (i) pharmacological inhibition of LRRK2 activity and (ii) silencing of the LRRK2 gene by the use of ASOs. Both options aim to reduce LRRK2 activity in the CNS whereby ASOs may bypass potential peripheral adverse effects of kinase inhibitors due to its intrathecal application in blood. A trial with DNL151, a second LRRK2 inhibitor, is still actively recruiting healthy volunteers the enhancement of PRKN or PINK1 expression, (ii) the prevention of Parkin or PINK1 inactivation, and (iii) the control of the downstream Parkin/PINK1 signaling pathway (Gaki and Papavassiliou PRKN or PINK1 mutation carriers) as listed in Table PRKN/PINK1 mutation carriers, heterozygous PRKN/PINK1 mutation carriers, and two IPD groups defined by the statistical extrema as determined by a mitochondrial PRS . Both studies have multimodal neuroimaging in common that will be applied as a surrogate marker for examining beneficial effects of in-vivo brain energy metabolism, i.e., by determining the change of energy equivalents using 31Phosphorus Magnetic Resonance Spectroscopy Imaging (31P-MRSI).Mitochondrial dysfunction is one of the main concepts in PD pathogenesis. Mitochondria play a fundamental role for a plethora of cellular processes relevant for the supply of energy, the overall cellular homeostasis, and neuronal survival. The first evidence for a role in PD derived from environmental studies illustrating the effect of neurotoxic agents in inhibiting the mitochondria's electron transport chain (ETC) . The disease-modifying management of PD is herewith more challenging due to the absence of validated and dynamic mechanism-based biomarkers.SNCA and high energy phosphates such as ATP levels (31P-MRSI) (Bonvento et al.

Clinical features can be inconclusive in mild and unusual WDSTS presentations with variable ID (mild to severe), facies and other associated malformations . Interpretation and classification of rare KMT2A variants can be challenging. A genome-wide DNA methylation episignature for KMT2A-related syndrome could allow functional classification of variants and provide insights into the pathophysiology of WDSTS. Therefore, we assessed genome-wide DNA methylation profiles in a cohort of 60 patients with clinical diagnosis for WDSTS or Kabuki and identified a unique highly sensitive and specific DNA methylation episignature as a molecular biomarker of WDSTS. WDSTS episignature enabled classification of variants of uncertain significance in the KMT2A gene as well as confirmation of diagnosis in patients with clinical presentation of WDSTS without known genetic variants. The changes in the methylation profile resulting from KMT2A mutations involve global reduction in methylation in various genes, including homeobox gene promoters. These findings provide novel insights into the molecular etiology of WDSTS and explain the broad phenotypic spectrum of the disease.Wiedemann\u2013Steiner syndrome (WDSTS) is a Mendelian syndromic intellectual disability (ID) condition associated with hypertrichosis cubiti, short stature, and characteristic facies caused by pathogenic variants in the Wiedemann\u2013Steiner syndrome is a rare severe autosomal dominant disorder, characterized by intellectual disability (ID), developmental delay, hypertrichosis cubiti and distinctive facial features ,5,6,7,8.The introduction of next-generation sequencing (NGS) and the implementation of human phenotype ontology (HPO) have revolutionized diagnostics for rare diseases .

The methylome analysis did highlight a substantial change in the global methylation pattern in WDSTS samples, and resulted in 87% hypomethylated and 13% hypermethylated probes. Our studies reported that the expression of several homeobox containing genes (including HOX or HOX-related genes) is consistently altered in the blood of WDSTS patients. If also present in other tissues, dysregulation of normal methylation of homeobox gene expression may explain part of the ID, facies and associated malformations observed in WDSTS patients. These provide novel insights into the molecular etiology of WDSTS and likely explain the broad phenotypic spectrum of the disease.In conclusion, the identified WDSTS DNA methylation episignature is added to the list of Mendelian NDDs with known DNA methylation episignatures that can be used for screening and diagnosis of NDD patients."} +{"text": "Biomarkers ideal for geroscience trials could be those simultaneously identified using targeted and discovery assays and which strongly associate with complementary disease (multimorbidity) and longevity outcomes. To identify a tractable set of biomarkers for use in geroscience trials, we used the Cardiovascular Health Study (CHS), whose participant makeup closely aligns with the Targeting Aging with MEtformin (TAME) trial. In ~4800 CHS participants, quantitative assays of nine a priori-identified biomarkers were used to construct a biomarker index which strongly associated with the TAME primary outcome of mortality and multimorbidity over 6 and 10 years of follow-up. In ~3000 CHS participants, 1300 proteins were measured with unbiased aptamer proteomics and associated with survival to age 90 over 25 years of follow-up. Proteins in the biomarker index were identified as some of the strongest associated with survival to 90.

Distinct tumor PSV, methylation, and expression patterns have been identified in BRCA2 compared with non-BRCA2 mutant prostate tumors. Several DNA damage response and repair (DDR)-targeting agents are currently being evaluated either as single agents or in combination in patients with PC. In this review article, we highlight the biology and clinical implications of deleterious inherited or acquired DNA repair pathway aberrations in PC and offer an overview of new agents being developed for the treatment of PC.Prostate cancer (PC) is the second most common cancer in men worldwide. Due to the large-scale sequencing efforts, there is currently a better understanding of the genomic landscape of PC. The identification of defects in DNA repair genes has led to clinical studies that provide a strong rationale for developing poly (ADP-ribose) polymerase (PARP) inhibitors and DNA-damaging agents in this molecularly defined subset of patients. The identification of molecularly defined subgroups of patients has also other clinical implications; for example, we now know that carriers of breast cancer 2 ( PSA decline of greater than 50% was observed in 50% of patients with BRCA1/2 and 3% of those with non-BRCA biallelic DDR gene alterations. Similar to olaparib, rucaparib was approved by the FDA for use amongst mCRPC patients with germline and/or somatic BRCA1/2 mutations undergoing prior progression on AR signaling inhibitor or taxane. Europe still awaits approval . Multiple phase I and phase II trials are evaluating immune checkpoint inhibitors in combination with treatments such as abiraterone and cabozantinib [NCT04477512], radiation therapy , and an experimental IL-8 directed monoclonal antibody [NCT03689699]. In addition, perioperative ipilimumab in combination with castration prior to radical prostatectomy has demonstrated feasibility with longer follow-up ongoing .DNA sequencing efforts have changed the molecular classification of prostate tumors and are leading to precision medicine strategies as well as defined prognosis and clinical features of molecular subsets of PC. Nevertheless, prospective studies demonstrating clinical value of biomarkers for prognostication or prediction of response are warranted. Somatic and germline DNA testing for patients with advanced PC should be considered in view of the therapeutic consequences for the patient and the possibility of pursuing targeted screening in this population. Metastatic tumor biopsies are recommended to obtain information regarding mCRPC tumor features. Germline samples are easily collected and analyzed, but still half of the patients with somatic DDR defects would not be identified. Liquid biopsies may be used to monitor for the detection of secondary mutations that may restore the function of a gene previously altered.PARP inhibitors represent one of the recent biggest therapeutic developments for PC patients. Combination of PARP inhibitor with AR-targeting agents is worthy due to the cross-regulation of both pathways and the central role of hormonal therapy in PC. Immunotherapy has shown still limited efficacy in these patients. However, immunotherapy combinations will probably overcome intrinsic resistance of PC to immunotherapy. Ongoing studies that assess the role of immunotherapy in PC are NCT04104893, NCT04019964 and NCT03570619."} +{"text": "OBJECTIVES/GOALS: The aim was to examine whether nicotine patch was more effective in encouraging abstinence from cigarettes smoking compared to placebo. METHODS/STUDY POPULATION: Randomized controlled trials involving the general teenage age group smokers who were current smokers-\u201csmoked less than 100 cigarettes over their lifetime and smoked at the time of the interview. Databases were searched for relevant studies reported in English that employed a randomized design published since 2000. Two authors extracted data and assessed quality. The primary outcomes and prioritization were continuous abstinence at 3, 6 and 12-month follow-up or more for the number of patients who responded to treatment, defined as a reduction/abstinence. Heterogeneity between studies did not preclude combined analyses of the data. RESULTS/ANTICIPATED RESULTS: 4 of 266 publications were included. Four studies reported positive effects on smoking cessation at end of treatment: (1) nicotine patches improved continuous abstinence at 6 weeks \u2013 9 weeks months; (2) nicotine patch improved continuous abstinence at 3 to 6 months; (3) nicotine patches improved continuous abstinence 6 and 12 months; (4) nicotine patches improved continuous abstinence at 6 months \u2013 12 and 24 months (5). All studies showed, continuous abstinence at follow up differed in percentage between groups both at 6 weeks through 24 months, with NRT (Nicotine patch) intervention groups achieving higher rates in most of the studies compared to placebo intervention group. Conclusions: NRT intervention methods seem to increase smoking abstinence in those treated for smoking cessation. Further and larger sample size studies are required to make stronger the base of evidence. DISCUSSION/SIGNIFICANCE OF IMPACT: Four randomized controlled trials investigating the effectiveness of smoking cessation interventions, for teenagers who smoke cigarettes were identified for inclusion in this review. Four of the studies reported significant effects on smoking cessation, providing evidence of effectiveness of NRT (nicotine patch), behavioral support and combinations of the two, although not all trials intervention treatments found an effect. The four studies reported important intervention effects at both the short and long follow-ups required: 6 weeks up to the 24 months, thereby, providing stronger evidence to support the effectiveness of NRT intervention on smoking cessation. All studies showed some evidence of improved smoking abstinence outcomes. The four studies had in common that the smoking cessation interventions provided a combination of intent to treat prevention, and of all the clinical trials none of them suggested a negative effect of smoking cessation treatment on substance use outcomes using NRT. However, the studies used reliable methods and reported their cases properly, but the small number of studies reviewed for the systematic review makes the conclusion about the effectiveness of these interventions uncertain.

Patients were contracted for 5-times weekly High frequency (10 Hz) rTMS for 4 weeks . Those who managed to complete their contracted TMS sessions were matched for age and sex with similar number of patients who received standard treatment as usual (TAU). Stimulation was as per FDA clearance for rTMS application in TRD.Eight patients were excluded (previous head trauma). A total of 46 patients had TMS mapping; nine of whom completed 20 sessions.Opioids was the most commonly used drug in almost 52% of patients (n = 14), followed by amphetamines in almost 30% (n = 8) and Cannabis in 18.5% (n = 5).Among those who completed 20 rTMS sessions; HADS scores on anxiety and depression fell by 85% and 78% respectively. BSCS score fell by 98%. Relapse rate (defined by positive drug screen) at 3 months was 33%.For those who completed 10 sessions; there was only 50% reduction on BSCS scores and 66% relapse rate. There were no data available on their HADS scores (only collected at baseline and at completion of 20 sessions).Those who only had TAU; there were no reduction in their BSCS (average score of 7 at both baseline and after 2 weeks).Our findings suggest that rTMS may be an effective and safe treatment for both depressive disorder and craving for SUD which is supported by other studies .Our study is probably the first of its kind within Middle East population with addiction problems."} +{"text": "CDHR1 alleles, and compare the associated phenotypes with previous reports.To describe the clinical and electrophysiological features of adult-onset macular dystrophy, due to novel combinations of CDHR1 were reviewed.

Therefore, in this study, we aimed to propose binding interactions of some benzimidazole-based anthelmintics with one of the most important cancer targets (Tubulin protein). Studied drugs were selected based on their structural similarity with the cocrystallized ligand (Nocodazole) with tubulin protein. Quantum mechanics calculations were also employed for characterization of electronic configuration of studied drugs at the atomic and molecular level. Order of binding affinities of tested benzimidazole drugs toward colchicine binding site on tubulin protein is as follows: Flubendazole > Oxfendazole > Nocodazole > Mebendazole > Albendazole > Oxibendazole > Fenbendazole > Ciclobendazole > Thiabendazole > Bendazole. By analyzing binding mode and hydrogen bond length between the nine studied benzimidazole drugs and colchicine binding site, Flubendazole was found to bind more efficiently with tubulin protein than other benzimidazole derivatives. The quantum mechanics studies showed that the electron density of HOMO of Flubendazole and Mebendazole together with their MEP map are quite similar to that of Nocodazole which is also consistent with the calculated binding affinities. Our study has ramifications for considering the repurposing of Flubendazole as a promising anticancer candidate. Microtubules play a key role in the invasion and metastatic spread of tumor cells, depending on its crucial roles in mitosis, signaling, trafficking, proliferation, and migration of eukaryotic cells . Drugs tThe success rate for new anticancer drugs from Phase I trial to commercial use by FDA approval is estimated to be around 6.7% from 2003 to 2011, taking about 8.3 years as an average . The ovede novo drug compounds and constitutes nowadays 30% of the newly marked drugs in the United States . DespiteIn vitro and in vivo studies revealed the potential of some members of benzimidazole anthelmintic drugs to suppress tumor progress through inhibition of multiple biological targets such as tubulin polymerization and angiogenesis (Benzimidazole anthelmintic drugs having over 40 years of safe use as over the counter medications . They arogenesis .Nocodazole (NZO) is a benzimidazole-based experimental drug targeting both protein kinases and microtubules. It is used as a lead compound for the discovery of novel CBSIs . In thishttps://pubchem.ncbi.nlm.nih.gov/). The nine tested compounds underwent energy minimization after examining the structure and the formal charges on atoms using a 2D depiction model. The partial charges were also automatically calculated. Structure of the co-crystallized NZO obtained from two subunits of the target tubulin protein (B and D subunits) and the nine tested benzimidazole drugs were imported together in the same database and saved in the form of MDB file to be docked in two separate processes for each subunit pocket, B and D, respectively.Docking studies using the Molecular Operating Environment (MOE) software package were perhttp://www.rcsb.org/). All steps for the preparation of the target protein for docking calculations were done. The addition of hydrogen atoms with their standard 3D geometry to the system, automatic correction to check for any errors in the connections and types of atoms, and fixation of the potential of the receptor were also performed. The selection of the same active site of co-crystallized inhibitor in the protein structure was done by using Site Finder where dummy atoms were created at the same binding site of the pocket.The X-ray structure for tubulin protein (PDB: 5CA1) complexed with the native NZO was obtained from the Protein Data Bank were used to approximately describe the polarity of colchicine binding pocket. All simulations were performed using GAUSSIAN 09 Revision C.01 based Becke\u2019s three-parameters Lee-Yang-Parr hybrid functional (B3LYP) was emplion C.01 on Swinb2O616). Hydrophobic interactions were also observed between Leu253 and the benzene and imidazole moieties. The 2D graphic views of binding interactions between studied benzimidazole ligands and NZO with the target protein are deposited in Crystallographic data of co-crystallized NZO complexed with tubulin protein (PDB: 5CA1) revealed the existence of two binding sites for NZO inside the protein, subunits B and D, respectively. It was obvious that subunit D is larger than subunit B in size. By analyzing the binding modes (3D graphic views) of NZO inside the two subunits , it was By studying the binding site in both B and D subunits, it was concluded that the crucial amino acids for binding interactions between CBSIs and the two subunits are Glu198 and Val236, besides Asn165 for B subunit and Cys239 for D subunit. The refined NZO was also docked among other studied benzimidazole drugs into subunits B and D to validate the molecular dynamic model used in conducting the current study. For the B subunit, the docked NZO showed almost a fingerprint binding mode as the original co-crystallized one. Interestingly, loss of binding interactions between the oxygen atom of its carbonyl group and Cys239 was also noticed. Furthermore, as expected, the binding interaction between N (3)-benzimidazole and Glu198 was lost in two subunits (B and D) as a result of using the neutral form of refined NZO in contrary to the protonated form of native NZO. The other nine benzimidazole drugs were refined and docked into NZO binding pocket subunits (B and D), respectively. Results revealed that all of the tested drugs, except for Thiabendazole (8) and Bendazole (9) members, showed very similar binding modes to the native NZO due to the great structural similarity. Regarding B subunit, Flubendazole (5) showed a nearly similar fingerprint binding mode compared to the native and docked forms of NZO. Concerning D subunit, surprisingly, Albendazole (2), Ciclobendazole (3), Flubendazole (5), and Oxfendazole (7) showed the binding interaction with Cys239 similar to the native NZO which was lost in the docked NZO itself. Especially Ciclobendazole (3) and Oxfendazole (7) showed a fingerprint binding interaction with Cys239 with the same direct and indirect pathways. It was concluded that Flubendazole (5) showed the highest similarity in binding modes compared to the native NZO in both B and D subunits of protein pocket. Furthermore, Thiabendazole (8) and Bendazole (9) lost some of the binding interactions compared to the native NZO due to the differences in the structure of side chains of their benzimidazole moieties but maintained the binding interactions with both Val236 and Asn165. By reviewing molecular dynamics scoring and other parameters listed in 2O616) calculated at 3.14\u00a0\u00c5 which is comparable to the same bond formed at 2.70\u00a0\u00c5 by the native NZO.Another confirmatory tool for validating the binding interactions between the tested ligands and the target protein is through measuring the lengths of H-bonds involved. By representing the 3D filling positions of our tested compounds inside the deep protein pockets of two subunits B and D compared to the co-crystallized inhibitor, we observed a very close similarity between all in each subunit confirming the same binding mode and structural similarity between them as shown in Moreover, the large size of the two pockets of subunits B and D, especially D subunit, gives us an idea about the possible drug modifications especially at the side chain of thiophene ring of NZO to obtain larger compounds that can occupy the binding pockets more efficiently maintaining the same essential binding interactions with the crucial amino acids and at the same time forming extra binding ones for better inhibition.It is well known that outermost electrons are those involved in the binding interaction between a ligand and target protein, we therefore, computed the electron density of the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO), and the molecular electrostatic potential (MEP) map. Figures of the electron density distribution of HOMO, LUMO, and MEP are depicted in The electron density of HOMO in NZO was found to be localized mainly on benzimidazole moiety, while the electron density of LUMO was solely localized on the thiophene side chain. The electron density of HOMO and LUMO of all other studied drugs are delocalized except for Mebendazole (1), Fenbendazole (4), and Flubendazole (5) in the case of HOMO and Oxibendazole (6) in case of LUMO. The electron density of HOMO of Mebendazole (1) and Flubendazole (5) is quite similar to that of NZO which is consistent with the calculated binding affinities [Flubendazole (5) > Oxfendazole (7) > NZO (docked) > Mebendazole (1)]. Despite of this consistency, the binding affinity does not solely depend on the energies and the electronic density distribution of HOMO and LUMO, but also on other determinants such as hydrogen bonding, electrostatic interactions, hydrophobic and Van der Waals forces and presence of clusters of water. We also noted that the electrons of HOMO are localized mainly on the benzene moiety and the aromatic side chain of Fenbendazole 4) in a different pattern to that observed with NZO.The MEP maps of all studied compounds revealed that one of benzimidazole nitrogen acts as an electron donating site capable of forming H-bond with amino acids in colchicine binding sites. Whereas the other benzimidazolyl nitrogen is electrophilic moiety acting as H-donor group. Interestingly, the MEP map of Mebendazole (1), Albendazole (2) and Flubendazole (5) are quite similar which is also consistent with the calculated binding affinities, where Flubendazole (5) > Oxfendazole (7) > NZO (docked) > Mebendazole (1) > Albendazole (2) > Oxibendazole (6) > Fenbendazole (4) > Ciclobendazole (3) > Thiabendazole (8) > Bendazole (9). Lack of 5 (6) substitution on the benzimidazole pharmacophoric group leads to a significant change in the MEP of Thiabendazole and Bendazole. Weaker binding affinities of these two drugs can be ascribed to the change in electronic configuration due to the absence of 5 (6) substitution.Among the nine tested members of benzimidazole anthelmintic drugs, Flubendazole (5) exhibits the most similar binding interactions, scoring, electron density distribution, and electrostatic map to that reported for NZO in tubulin protein (PDB: 5CA1). This suggests that Flubendazole (5) would be the most active member exerting antitumor activity mainly at CBS. At the same time, more structural modifications are required for FDA approved benzimidazole anthelmintic drugs and the original NZO inhibitor to obtain larger compounds with better fitting and binding modes inside the two large pockets of subunits B and D respectively."} +{"text": "This Correction follows an Expression of Concern relating to this article previously published by Portland Press.Fragaria ananassa methanolic extract in a rat model of cadmium chloride-induced neurotoxicity\u201d (Biosci Rep (2018) 38(6), DOI: 10.1042/BSR20180861) would like to correct The authors of the original article \u201cProtective effects of The authors have stated that the overlapping images had been selected from the same group in error, and further confirm that this error does not affect the conclusions of their study.

Some associative and dissociative maneuvers for dissociating a certain electrical signal from others of known origin are used to ascertain the source of an unknown potential. Figure 1 was obtained. The arrow points to a signal after the ventricular potential on the His-bundle (HB) catheter that was consistently seen in sinus rhythm . What could be the origin of this second unexpected potential?A 64-year-old man with recurrent episodes of wide QRS tachycardia with the absence of overt structural heart disease underwent an electrophysiological evaluation. An echocardiogram showed mildly depressed left ventricular function. During an electrophysiological study, the electrogram in 2 A wide range of diagnoses are possible, including (1) intermittent accessory pathway (AP) conduction with an antegrade 2-for-1 phenomenon, (2) intermittent fused premature ventricular complexes (PVCs) arising from the diseased tissue near the HB region, (3) intermittent right bundle ectopy, (4) intermittent nodoventricular (NV) conduction, (5) intermittent atriofascicular (Mahaim fiber) conduction, (6) fragmented ventricular potential, or (7) basal septal or periaortic ventricular late potentials and local abnormal ventricular activities (LAVAs).3 Mahaim fibers or the NV pathway may also produce a second HB deflection after the ventricular potential on the HB catheter because of the retrograde conduction of the right bundle.2 Other antegrade-conducting unusual AP connections from the right atrial appendage to the right ventricular outflow tract may also cause complex signals on the HB catheter. A 2-for-1 phenomenon can occur when the atrial impulse simultaneously travels down the AP (activating the annular ventricular myocardium) and the atrioventricular node (AVN) and the HB . Afterward, the ventricular activation wavefront may travel back toward the base .1The presence of 2 ventricular signals caused by structures near the HB region is rare.5 The atrial extra-stimulus testing might give us some important clues. The timing of the extra potential is expected to correlate with either the degree of pre-excitation or the amount of fusion (if a PVC or fascicular beat occurs). If the candidate signal is ventricular or otherwise associated with pre-excitation , then causing a delay to signal activation would cause less pre-excitation.2 In the current case, there was a delay from the atrial signal to both the HB and the candidate potential without a change in the degree of pre-excitation an atrial extra-stimulus beat that showed more decrement in conduction down the AVN. A relatively fixed relationship was seen with V to this potential (single arrows), with a further delay with S2 (double arrow) in activating the tissue responsible for the extra (unexplained) potential. However, it would be difficult to explain the phenomenon via the effects of atrial pacing with a Mahaim fiber.2 For this to occur, a very similar decrement in conduction down the Mahaim fiber and the AVN is needed. The delay to the extra potential despite AH prolongation excluded all AP-related diagnostic possibilities in the current case, including NV pathways.8 Electroanatomic mapping revealed periaortic fibrosis that was consistent with this unusual potential , and then 4 different ventricular tachycardia (VT) morphologies were induced .Some associative and dissociative maneuvers for dissociating a certain electrical signal from others of known origin are used to ascertain the source of an unknown potential.11 These VTs from small regions of the periaortic scar can mimic idiopathic VT but are suggested by multiple VT morphologies .12 Several methods have been studied to invoke dynamic substrate changes in critical regions to target ablation, including decrement-evoked potential mapping,5 which involves a drivetrain and an S2 pacing protocol identifying sites of decremental LAVAs. This small periaortic site was then targeted for radiofrequency ablation . During ablation, the amplitude of this potential decreased, and all VT morphologies were no longer seen. Electrophysiologists must have a thorough understanding of how unexplained potentials can be analyzed using pacing maneuvers and by observing changes of association and dissociation that occur between these unknown signals and other known potentials .1 These techniques are useful in identifying the culprit sites and targets for ablation for several arrhythmias.2Periaortic fibrosis is increasingly recognized as a distinct clinical substrate for scar-related VT in the presence and absence of overt structural heart disease."} +{"text": "From th studies .Medline (Pubmed) search using the following: \u201cvascularization maxillary sinus cadavers\u201d, completed with the revision of the bibliographical references of the selected articles in order to identify further relevant studies.

A comparably high sensitivity of 92% (95% CI: 86\u201398) and specificity of 89% (95% CI: 78\u2013100) were shown in testing based on detection of the combination of anti-LPS (IgA and IgM) and anti-HlyE IgG as well as a slightly lower sensitivity of 91% (95% CI: 74\u2013100) in the case of anti-50kDa IgA. Anti-50kDa IgM had the lowest sensitivity of 36% (95% CI: 6\u201365) against both healthy and febrile controls. The development of a rapid diagnostic test targeting antibodies against lipopolysaccharides combined with flagellin appeared to be a suitable approach for the rapid detection test of typhoid fever. Saliva is added benefit for rapid typhoid diagnosis since it is less invasive. As a result, further studies could be done to develop additional approaches for adopting such samples.

A systematic analysis by typhoid and paratyphoid collaborators estimated that 10.9 million cases of typhoid fever occurred globally in 2017, resulting in 116.8 thousand deaths AND [\u201cantigen\u201d OR \u201cantibody\u201d] AND [\u201cdiagnosis\u201d OR diagnostic\u201d] AND [\u201cspecificity\u201d OR \u201csensitivity\u201d]. An additional search was conducted by manually screening the references of the retrieved literature.The literature search was conducted in January 2021 according to the modified preferred reporting items for systematic reviews and meta-analyses guidelines . The seaArticles were excluded if (i) the studies were published before 1 January 2011, or after 31 December 2020; (ii) the studies were published in languages other than English or Malay; (iii) the studies did not mention the types of antigens used. We limit the studies to post 2011 (10 years) as the older literatures are not relevance to represent current diagnostic performance of the newly developed assays. Only studies that analyzed samples of at least two groups consisting of healthy controls and typhoid patients confirmed by positive blood culture were included in this systematic review. The retrieved literature was downloaded into Mendeley reference manager and duplicates were identified and removed. The references were distributed to four authors, who independently reviewed the titles and abstracts. A satisfactory agreement for the screening process was assessed between the reviewers. All four reviewers performed full-text screening and summarized the findings. Data from the selected sources were collated and summarized using a standard charting table consisting of six domains: (i) detection assays; (ii) biomarker; (iii) biological specimens; (iv) sample size; (v) specificity and sensitivity; (vi) year of publication.The number of true positives (TF), true negatives (TN), false positives (FP) and false negatives (FN) was independently retrieved from each article by three investigators and entered into an Excel datasheet. Discordant findings were assessed through discussion and when in doubt, the authors sought verification. Using blood culture as the reference standard, we calculated the sensitivity and specificity for each of the studied biomarker. Sensitivity was calculated by dividing the number of true positive outcomes with the sum of true positive and false negative outcomes. Specificity was calculated by dividing the number of true negative outcomes with the sum of true negative and false positive outcomes. Performance comparison of the immunodiagnostic assays was presented using forest plots based on control groups.The risk of bias for all included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool . The QUAThe present systematic review provides an overview of the performance of immunodiagnostic tests for typhoid fever and found that tests based on anti-LPS in combination with anti-flagellin offered the best diagnostic performance for the diagnosis of typhoid fever and that anti-HlyE could be an alternative option with a performance comparable to that of anti-LPS. Our results highlight the limitations of the ongoing immunodiagnostic development and provide baseline information for future studies to select appropriate biomarkers in the development of RDTs for typhoid fever. Based on the good performance of anti-LPS and anti-HlyE, these two antigens appear to be suitable options for the development of future POCTs for typhoid fever. The currently low number of studies using saliva samples for detection suggests that more studies could explore the development of alternative approaches implementing such samples, which have the advantages of less invasive sample collection, which would help to boost accessibility and facilitate efficient testing in a community, especially during a disease outbreak and in areas where access to laboratory-based testing is not available."} +{"text": "This study aimed to assess the impact that the COVID-19 pandemic has had on the Hertfordshire Community Perinatal Team (CPT) group interventions and the innovations made.The CPT is a multidisciplinary mental health service that runs three groups: Circle of Security (CoS), Emotional Coping Skills (ECS) and a peer support group - Wellbeing and Lifestyle. The service has received an increase in referrals during the COVID-19 pandemic.Methods: Team member and client semi structured interviews were conducted with answers transcribed in real time and analysed.

A solution to this problem was found to be using a laryngoscope to guide the ETT tip to the same immediately supraglottic position that had always been a part of NLPAWS use during nasotracheal intubation.2 Two advantages of this technique of rescue ventilation compared to similar use of a laryngeal mask airway (LMA) are (1) faster access to an ETT and (2) suitability of almost any ETT size.At first, we used NLPAWS to permit ventilation through an oral ETT inserted a distance approximating the length of an appropriately sized oral airway.2 and PEEP 20 cm H2O) to reverse a rapid decline in blood oxygenation (SpO2 88% \u2192 42%) and elevate it to 58% during the time required for a replacement ETT to be brought to the patient's negative-pressure intensive care unit room.Very recently, members of our department have learned to use NLPAWS to enable PPV (1) in the presence of a leaking LMA (5 cases); (2) via a nasal airway fitted with an ETT adaptor during upper GI endoscopy ; and (3) via a correctly inserted ETT (4 cases).

Chronic inflammation induces adaptive changes that can cause altered pain signal processes. Indeed, inflammatory mediators provokes structural and functional changes in the peripheral or central sensory circuits, resulting in pain like behaviors, such as hyperalgesia, allodynia, and spontaneous pain. Accumulating evidence suggests that central sensitization is driven by neuroinflammatory processes mediated by activation/proliferation of resident microglia and glial cells with the consequent release of inflammatory mediators; furthermore, several recent studies are relating the role of non-neuronal cells of the peripheral nervous system with the modulation of neuroinflammation involved in the development and maintenance of chronic pain.Boccella et al.).Currently treatments for chronic pain are quite unsatisfying.

Excellent conversion to the desired addition product 3a was observed in the presence of a stoichiometric amountof tert-butyldimethylsilyl triflate (TBDMSOTf) afterstirring overnight (Supporting Information) confirmed the conditions in entry 1 as the mostoptimal. Next, we evaluated the effect of the protecting group ofthe quinolone substrate on the reaction outcome.At the start of this work, the optimization studies were carriedout for the alkynylation reaction between Cbz-protected quinolone 3a were obtained when trimethylsilylhalides were used instead (entries 9 and 10). The use of strongersilicon-based Lewis acids such as trimethylsilyl (TMS) and triethylsilyl(TES) triflates resulted in moderate reaction rates (entries 11 and12), whereas the boron-based Lewis acid BF3\u00b7Et2O did not improve the reaction outcome either (entry 13).The superiority of TBDMSOTf over other explored silyl triflates canbe rationalized by the higher stability of a possible TBDMS-enolateintermediate formed during the reaction.No conversion was observed whenunprotected or benzyl-protectedquinolones were used (entries 3 and 4). Moreover, replacing the Cbzprotecting group on the quinolone substrate by a Boc group resultedin a significant drop in the conversion (entry 5). Further studiesconfirmed that the presence of a copper salt and a stoichiometricamount of a Lewis acid are mandatory to promote the reaction to completion.No conversion of quinolone was observed in the absence of copper saltor using only a catalytic amount of a Lewis acid (entries 6\u20138).With silyl-based Lewis acids other than TBDMSOTf, a lower substrateconversion was obtained (entries 9\u201313).

Similar results were obtainedwhen using cyclopropyl-, isobutyl-, and ester-substituted alkynes. Surprisingly, the linearterminal alkyne 1-pentyne was unreactive under the optimized reactionconditions (3ao). The limited reactivity of alkyl alkynesand the lack of reactivity of linear alkynes are consistent with theliterature observations in other Cu-catalyzed reactions.37 Various quinolones can be usedwith this catalytic system. Excellent yields were obtained for quinolonesboth with activating and with deactivating groups present in the quinolonering (3eg\u20133ig) and for those withdisubstituted substrates (3jg and 3kg).The reaction was successfully extendedto several aromatic terminalalkynes bearing electron-donating and electron-withdrawing groupsand four-, three-, and two-substituted aromatic rings -cuspareine (5)without racemization, allowing the determination of the absolute configurationof the stereogenic carbon by comparing the optical rotation of cuspareinewith literature data.17The hydrogenation of In summary, an efficientmethodology for the alkynylation of quinoloneswith readily available terminal alkynes has been accomplished.

Results showed that social isolation, both family and friendship isolation, was significantly associated with higher risks of having sleep difficulty. The adverse effect of family isolation was found to be stronger than that of friendship isolation.

Urease is a metallohydrolases that catalyses the hydrolysis of urea into ammonia and carbon dioxide, causing an abrupt increase of pH. This enzymatic activity can be employed to target the acidic tumour microenvironment. In this study, we present the anticancer activities of urease mimetic cobalt (III) complexes on A549 cells. The cells were treated with different doses of cobalt (III) complexes to observe the cytotoxicity. The change in cellular morphology was observed using an inverted microscope. The cell death induced by these complexes was analysed through ATP proliferation, LDH release and caspase 3/7 activity. The effect of extracellular alkalinization by the cobalt (III) complexes on the efficacy of the weakly basic drug, doxorubicin (dox) was also evaluated. This combination therapy of dox with cobalt (III) complexes resulted in enhanced apoptosis in A549 cells, as evidenced by elevated caspase 3/7 activity in treated groups. The study confirms the urease mimicking anticancer activity of cobalt (III) complexes by neutralizing the tumour microenvironment. This study will motivate the applications of transition metal-based enzyme mimics in targeting the tumour microenvironment for effective anticancer treatments. The last few decades have seen an upsurge in cancer research. Many developments and milestones have been achieved in discovering compounds with effective anticancer therapeutic properties. Although a lot of such potent drugs such as doxorubicin and cisplatin were discovered several years ago and are still used clinically to treat different kinds of cancers; they are often limited by severe side effects on healthy cells ,2. RecenRecently, some researchers have focused on targeting the microenvironment surrounding tumour cells ,15,16,17Urease is widespread in nature and is present in various forms in several bacteria, fungi, and algae . It is c2\u00b76H2O , tris(2\u2013aminoethyl)amine , triethylaminetetramine , and urea were used as obtained. The complexes were prepared following literature methods Cl (III) and [Co(tren)Cl2]Cl (IV)) was measured from the culture media of the treated and untreated groups. 100 \u03bcL of the culture media was withdrawn from treated and untreated groups at fixed time intervals and the urease mimetic activity was measured using the urease activity kit from Merck Sigma-Aldrich, MAK120, following the protocol provided.The urease mimetic activity of the chloro complexes, (Cl (II) and [Co(trien)Cl2]Cl (III). The crystals were analysed by SC-XRD analyses and were found to be structurally similar to the initial compounds. The crystal structures are presented in 2]Cl was similar to the starting material, the [Co(tren)(NO2)2]Cl crystallised as a polymorph in a different space group. The most prevalent polymorph for this compound exists in orthorhombic space group (Pbca), and the only reported monoclinic form (A2) was isolated serendipitously Cl (IV) induced cleavage of urea into ammonia was reported by some of us recently. The increasing alkalinity was monitored spectrophotometrically with the aid of a pH dependent indicator, phenolphthalein Cl (IV) and [Co(trien)Cl2]Cl (III) were found to be slightly basic as compared to the other groups. This prompted us to measure the urease mimetic activity of the chloro complexes under treatment conditions. Therefore, confluent cells in culture dishes were treated with the optimised dose of the cobalt (III) complexes (32 \u03bcM) in the presence of urea (2 mM). The results were compared to cells treated with urea alone (2 mM) (untreated group) to negate any background absorbance that may arise due to the culture medium or urea. A total of 100 \u03bcL of the culture medium was withdrawn at fixed time intervals, and the urease mimetic activity was measured using the urease activity kit from Sigma Aldrich as per the protocol available with the test kit. The increase in absorbance at 670 nm at fixed time intervals for the cobalt treated groups was compared to the untreated group. The results are presented in 2]Cl (IV) and [Co(trien)Cl2]Cl (III) depicted a gradual increase in absorbance at 670 nm, and after 24 h of treatment, the absorbance, and hence the urease mimetic activity for [Co(tren)Cl2]Cl (IV) was significantly higher than [Co(trien)Cl2]Cl (III). Similar trends have been reported for catalytic studies as well [2]Cl (IV) performing better than [Co(trien)Cl2]Cl (III) for A549 cells.The ammonia generated because of urease mimetic activity in treatment groups was ascertained by pH measurements of the cell culture media after 24 h of treatment of A549 cells with the cobalt (III) complexes. Interestingly, the culture media from the cells treated with Cl (IV) and [Co(trien)Cl2]Cl (III) over 24 h complexes for MCF7 cells were completely surprising and conflicting. There was no appreciable change in absorbance at 670 nm for the cells treated with [Co(tren)Clver 24 h . The abs2]Cl (III) and [Co(tren)Cl2]Cl (IV) complexes outperformed other Co complexes (2)2]Cl (II) and [Co(trien)(NO2)2]Cl (I) complexes exhibit poor catalytic urease activity as well, owing to the strong affinity and poor lability of the nitro group towards cobalt [The WS1 cells in the control and treated groups were seen to be healthy with no significant difference observed in growth and proliferation . The LDHomplexes A. The [Cs cobalt .2]Cl (III) and [Co(tren)Cl2]Cl (IV), while the nitro complexes were dropped out. To ascertain the urease-like anticancer activity of the cobalt complexes, the cells were treated with the complexes alone and with the addition of urea. The resulting alkalinity of urease activity has been shown to enhance the activity of weakly basic anticancer drugs, such as doxorubicin. Such drugs\u2013enzyme combinations and conjugates are gaining increasing attention in recent times Cl (III) and [Co(tren)Cl2]Cl (IV))\u2013urea combination as well as the combinations with doxorubicin, induced profuse toxicity in cells and reduction of ATP. These findings further support our claim that urease mimetic activity of the cobalt complexes induces anticancer effects by facilitating doxorubicin action, as observed in the LDH assay. The results are presented in A similar trend was observed with ATP of WS1 and A549 cells. No significant ATP proliferation was observed in WS1 cells depicting the safety of complexes against normal cells ; howeverThe A549 cells which were incubated with the cobalt complexes alone and in combination with urea and doxorubicin for 24 h showed distinct morphology in a concentration dependent manner compared to the control. The cells showed signs of cell death, with deformed membrane integrity, losing inter-cellular contact, vacuolation, rounding of cells and detachment from the culture plates . The toxAs observed in LDH and ATP assays, cell viability significantly reduced in A549 cells on treatment with the cobalt complexes and the urea and doxorubicin combinations . The celIII and IV) in combination with urea and doxorubicin. The luminescent signals elevated in these groups compared to control and authenticate the role of caspases in inducing cell death complexes towards cancer cells. Such altering of the microenvironment can also be manipulated to enhance the activity of weakly basic drugs. Under acidic conditions, basic drugs, such as doxorubicin, tend to sequester in the acidic extracellular environment, thus failing to diffuse into the hydrophobic cell membrane. This often results in loss of therapeutic activity and drug resistance. In this study, we report a combination therapy of the cobalt (III) complexes with doxorubicin. The combination is proposed to be working synergistically, wherein the cobalt (III) complexes hydrolyse urea to generate ammonia, thus neutralizing the acidity in the tumour microenvironment. This subsequently, enhances the diffusion of doxorubicin into the cells, thereby, improving the overall cytotoxic activity. The cobalt complexes do not directly target the cancer cells; rather, they act on the extracellular microenvironment, disrupting the physiological factors that enable tumour growth. Thus, they exert a target specific cytotoxic action controlled by the surrounding pH. This can also be attributed to the low toxicity of the complexes towards normal cells that operate under strictly controlled pH conditions. To further confirm the mechanism of apoptotic action, caspase 3/7 expression was determined in treated groups. Even though the cell death stimulus induced by caspase 3 and 7 differs, they are yet considered universal executioner caspases ,53,54. AUrease activity was long viewed as detrimental, and research was mainly focused on inhibiting the enzyme\u2019s activity; however, the undesirable urease activity can be utilized to neutralize the acidity in tumour microenvironments, thereby leading to enhanced therapeutic efficiency. We have presented the preliminary results of the cytotoxicity induced by urease mimetic cobalt (III) complexes on lung cancer cells. The cytotoxicity results correlate well with the observed urease mimetic activity. The complexes reported in this study are found to be nontoxic towards normal cells, making them an ideal drug candidate for treating cancer cells. To further understand the application of these complexes as anticancer drugs, their dose responses on MCF-7 and HKESC-1 were also studied. With moderate toxicity on MCF-7 but commendable action against HKESC-1 cells, it can be concluded that the active complexes (III and IV) were not cell line specific and further research is warranted to understand the reason behind these specificities. Moreover, synthetic enzyme mimics based on transition metal complexes serve several advantages over the actual enzyme; they are robust, with long shelf life, and often can greatly reduce the cost of manufacturing. The urease, like the action of the cobalt (III) complexes, also improves the therapeutic activity of weakly basic drugs, such as doxorubicin, by inducing apoptosis as seen by the expression of caspase3/7 in treated groups; however, the conflicting results obtained with MCF7 cell lines warrant further investigation using in vivo and clinical models. The concept introduced in this article is worthwhile and deserves further investigation."} +{"text": "ABSTRACT IMPACT: Being explicit about the prevention of falls throughout an older adults\u2019 episode of care may further help reinforce the role of physical therapy providers in falls prevention and improve dissemination of this knowledge. OBJECTIVES/GOALS: The purpose of this study was to determine older adults\u2019 awareness of and perspectives about the role of physical therapy providers for falls prevention and determine potential barriers and facilitators to utilization of preventive rehabilitation services METHODS/STUDY POPULATION: We used a qualitative descriptive phenomenological approach to emphasize participants\u2019 perceptions and lived experiences.

To meet this objective, 247 randomly selected reference samples, earlier being processed with conventional capillary electrophoretic (CE) STR sizing from the Austrian National DNA Database, were reanalyzed with the PowerSeq 46Y kit (Promega). This sample set provides MPS-based population data valid for the Austrian population to increase the body of sequence-based STR variation. The study addressed forensically relevant parameters, such as concordance and backward compatibility to extant amplicon-based genotypes, sequence-based stutter ratios, and relative marker performance. Of the 22 autosomal STR loci included in the PowerSeq 46GY panel, 99.98% of the allele calls were concordant between MPS and CE. Moreover, 25 new sequence variants from 15 markers were found in the Austrian dataset that are yet undescribed in the STRSeq online catalogue and were submitted for inclusion. Despite the high degree of concordance between MPS and CE derived genotypes, our results demonstrate the need for a harmonized allele nomenclature system that is equally applicable to both technologies, but at the same time can take advantage of the increased information content of MPS. This appears to be particularly important with regard to database applications in order to prevent false exclusions due to varying allele naming based on different analysis platforms and ensures backward compatibility.The online version contains supplementary material available at 10.1007/s00414-021-02685-x.

TSC mutation leads to continuous activation of the mTOR pathway that requires adaptation to increased ATP requirement. With limited treatment options, there is an increasing demand to identify novel therapeutic targets and to understand the correlations between mTOR pathway activation and the lack of cell death in the presence of TSC mutation. In the current study, we demonstrate deregulation of p53 controlled and mitochondria associated cell death processes. The study also reveals that treatment of TSC mutant cells with the drug candidate Proxison combined with reduced concentration of rapamycin can increase production of reactive oxygen species (ROS), can modify miRNA expression pattern associated with p53 regulation and can reduce cell viability.The online version contains supplementary material available at 10.1007/s10495-021-01670-4. RecentlIn a previous study of lymphangioleiomyomatosis (LAM) TSC mutaTSC mutations are particularly disruptive in the phosphoinositide 3 kinase (PI3K)/Protein kinase B (PKB or AKT)/mTOR pathway, as the mTOR pathway is inhibited by the complex of two proteins Hamartin (TSC1) and Tuberin (TSC2). Mutation in the TSC genes allows continuous activation of mTOR resulting in slow growing neoplasms . The mTOBased on the above we theorized that investigation and modulation of p53 and mitochondrial function associated cell death pathways might provide a better understanding of the molecular background of TSC mutation induced diseases and the results might lead to identification of additional targets for therapy.Materials and methods are detailed in the Supplementary material .

This syndrome is infrequent and corresponds to a peculiar small subgroup of patients with symptomatic gallstone disease. The patients with the LPAC syndrome present typically with the following main features: age less than 40 years at onset of symptoms, recurrence of biliary symptoms after cholecystectomy, intrahepatic hyperechoic foci or sludge or microlithiasis along the biliary tree. Defect in ABCB4 function causes the production of bile with low phospholipid content, increased lithogenicity and high detergent properties leading to bile duct luminal membrane injuries and resulting in cholestasis with increased serum gamma-glutamyltransferase (GGT) activity. Intrahepatic gallstones may be evidenced by ultrasonography (US), computing tomography (CT) abdominal scan or magnetic resonance cholangiopancreatography, intrahepatic hyperechogenic foci along the biliary tree may be evidenced by US, and hepatic bile composition (phospholipids) may be determined by duodenoscopy. In all cases where the ABCB4 genotyping confirms the diagnosis of LPAC syndrome in young adults, long-term curative or prophylactic therapy with ursodeoxycholic acid (UDCA) should be initiated early to prevent the occurrence or recurrence of the syndrome and its complications. Cholecystectomy is indicated in the case of symptomatic gallstones. Biliary drainage or partial hepatectomy may be indicated in the case of symptomatic intrahepatic bile duct dilatations filled with gallstones. Patients with end-stage liver disease may be candidates for liver transplantation.Low phospholipid-associated cholelithiasis (LPAC) is characterized by the association of Low phospholipid associated cholelithiasisABCB4 gene mutationCholelithiasis with ABCB4 gene mutation-associated cholelithiasisABCB4 mutations with symptomatic and recurring cholelithiasis in young adults (e.g. <40 years).Low phospholipid-associated cholelithiasis (LPAC) is characterized by the association of ABCB4 mutations in the whole population of patients with cholelithiasis.The exact prevalence of LPAC remains unknown. The disease is more common in young adults, the usual age at the onset of the symptoms is typically lower than 40 years. The male to female ratio is estimated at approximately 1:3. However, at present, the literature data and our results did not allow to determine the frequency of Up to 10% of the European and American population carry gallstones, approximately 25% of cases have symptoms and less than 2% present with severe complications (cholangitis or pancreatitis). Based on previous epidemiological data, we consider that LPAC syndrome is infrequent and corresponds to a peculiar subgroup of patients with symptomatic gallstone disease [LPAC presents as a peculiar form of cholelithiasis characterized by cholecystitis, cholangitis and intrahepatic gallstone disease, and/or acute pancreatitis associated with biliary microlithiasis. Most patients report a history of cholesterol gallstones amongst their first-degree relatives. Intrahepatic hyperechoic foci are characteristic sign of the LPAC syndrome. Intrahepatic gallstones or sludge and increased serum gamma-glutamyl transferase (GGT) activity are frequently present. It suggests that the biliary symptoms experienced by these patients are probably caused by cholesterol crystal deposits and bile duct inflammation but not directly and exclusively related to the presence of detectable gallstones. Increased cholesterol saturation index and a defect in the hepatic transport and biliary secretion of phospholipids in patients with an intrahepatic cholesterol gallstone disease or an acute pancreatitis associated with biliary microlithiasis have been shown in another studies ,4.ABCB4 mutations presented also with an history of intrahepatic cholestasis of pregnancy and 14% had fetal complications) [The typical biliary pain in patients with LPAC syndrome often leads to decision of cholecystectomy.

We identified 14 heterozygous and homozygous point mutations amongst these 18 patients. None of these mutations was detected in a control panel of 140 chromosomes demonstrating that they did not correspond to polymorphisms (SNPs). Affected patients with heterozygous mutations exhibited 1bp-insertion, 1bp-deletion, nonsense mutations or missense mutations resulting in a frameshift predicted to cause premature messenger RNA termination, a loss of protein function and single-nucleotide substitutions, while affected patients with homozygous mutations demonstrated only missense mutations. Most mutations were localized in the central part of the molecule, close to nucleotide binding domain 1 (NBD1), or in adjacent transmembrane domains and intracellular loops .Patients were screened for mutations in the st intracellular loop and resulted in a substitution in a conserved cluster of four amino-acids at position 169\u2013172, required for the adenosine triphosphatase activity of the molecule. This mutant resulted in a complete loss of drug-induced P-gp ATPase activity. The Phe165Ile mutation was localized in the same part of this intracellular loop and may therefore give rise to a similar defect. The Glu528Asp mutation was localized close to the NBD1. The glutamic acid is included in a small amino-acid cluster localized before the walker B motif which is required for drug-induced ATPase activity. These mutations indeed induced a loss of function of the molecule in vitro. It should be noted that the two unrelated patients in whom the Thr175Ala mutation was identified originated from Northern Europe, so they may have inherited a founder mutation from a shared ancestor. This mutation has also been recently identified in adults with cholangiopathy and intrahepatic cholestasis of pregnancy [The definition of a disease-causing mutation (DCM) is problematic when functional assays to determine the phenotypic effects of specific variants are not available or have not been performed. To date, two of the missense mutations (Glu528Asp and Thr175Ala) detected in patients with the LPAC syndrome had been analyzed previously in a homolog of ABCB4 in yeast ,14. The regnancy . The mutregnancy .ABCB4 sequence alterations leading to predicted premature truncation of the protein, small deletions or insertions and non-conserved missense mutations were considered as potential DCMs. Even if this restriction was taken into account, a certain number of arguments strongly supported a pathogenic role for ABCB4 gene mutations. These mutations are indeed detected at high frequency in patients with LPAC syndrome; they affect only highly conserved amino acids between human and rodent homologues of the gene and no mutation was detected in an independent control panel of 140 chromosomes. In addition, LPAC syndrome was observed in patients exhibiting the same or similar nonsense or missense mutations: in a mother and her elder son with an identical heterozygous nonsense mutation (1327insA); in independent patients from non-consanguineous families with the same homozygous missense mutation (Ser320Phe or Ala934Thr), while their heterozygous parents were asymptomatic; in patients with a similar nonsense mutation (1006-1016insT and 1006-1016delT) and in unrelated patients with the same missense mutations (Pro1161Ser). For all these reasons, these mutations could be considered as causing the LPAC syndrome.Only ABCB4 mutations may lead to cholesterol cholelithiasis when residual ABCB4 activity and subsequent biliary phospholipid secretion fall below a critical threshold which may depend on the type of mutation and on other host or environmental factors, including probably bacterial infection of the bile ducts .These results and data in the literature therefore strongly suggest that ABCB4 gene point mutation, defects in the promoter region or large DNA rearrangements might also be involved in some patients presenting with LPAC syndrome.

The ability of hypoxanthine (HX) to modulate the effects of two antifolates-ICI 198583 (an inhibitor of thymidylate synthetase) and piritrexim -was investigated using cultured mouse leukaemic cells, L1210. HX (10(-4) M) was found to potentiate only the cytotoxicity of DHFR inhibitors (MTS and PTX), increasing cell kill by 20-70 fold to the level achieved by an equivalent concentration (10(-5) M) of ICI 198583 alone. Agarose gel electrophoresis of DNA extracted from cells exposed to antifolates for 24 h demonstrated that the chromatin was cleaved into multimers of 200 base pairs. This pattern of DNA cleavage indicates cell death via apoptosis. The degree of DNA fragmentation was found to be closely linked to cytotoxicity. DNA fragmentation increased from 50% in cells treated with 10(-5) M MTX or PTX to 70% when HX was added with the drugs, a level achieved by 10(-5)M ICI 198583 alone. HX potentiation of cytotoxicity was correlated with a substantial increase in dATP in conjunction with low dTTP pools. The specific potentiation of DHFR inhibitors by HX may be due to their inhibition of purine synthesis with a concurrent rise in PRPP levels. Addition of HX with MTX substantially raised intracellular purine levels via the salvage pathway as indicated by ribonucleotide pool measurements. ICI 198583, on the other hand, stimulated de novo purine synthesis with or without added HX. Treatment with MTX plus HX or ICI 198583 (with or without HX) caused a reduction of dTTP pools to 8% of untreated control and excess dATP accumulation. The subsequent elevation (to 300% of control) of the dATP pool may provide a signal for endonucleolytic fragmentation of DNA and subsequent cell death."} +{"text": "Eighty-four patients with breast cancer at high risk of bone metastases were investigated with magnetic resonance imaging (MRI) of the thoracolumbar spine.

In order to better define the association between DHBV infection, AFB1 and HCC we analysed a series of 16 duck liver samples collected from local farms in Qidong. HCC was found in eight and cirrhosis in one of these samples. Furthermore bile duct proliferation, characteristic of AFB1 exposure in ducks and other animal species, was found in these ducks. Integration of DHBV DNA into cellular DNA was observed in only one out of four DHBV positive HCCs, indicating that viral integration is not prerequisite for tumour development.

The cells under continuous exogenous and endogenous genotoxic stress accumulate DNA errors, drive proliferative expansion and transform into cancer stem cells with a heterogeneous population of tumor cells. These cells are a common phenomenon for the hematological malignancies and solid tumors. In response to DNA damage, the complex cellular mechanisms including cell cycle arrest, transcription induction and DNA repair are activated. The cells when exposed to cytotoxic agents, the apoptosis lead to cell death. However, the absence of repair machinery makes the cells resistant to tumor sensitizing agents and result in malignant transformation. Mismatch repair gene defects are recently identified in hematopoietic malignancies, leukemia and lymphoma cell lines. This review emphasizes the importance of MMR systems in maintaining the stem cell functioning and its therapeutic implications in the eradication of cancer stem cells and differentiated tumor cells as well. The understanding of the biological functions of mismatch repair in the stem cells and its malignant counterparts could help in developing an effective novel therapies leaving residual non-tumorigenic population of cells resulting in potential cancer cures. Gurdon first introduced the concept of stemness state of the cells while successfully achieving the generation of all cell lineages of a living tadpole after transferring the nuclei from intestinal epithelial cells of feeding Xenopus tadpoles to activated enucleated eggs ,2. TheseThe multipotency of stem cells to maintain tissue homeostasis and its differentiation into mature cell types is under a tightly controlled system and is associated with restricted expression profile. The expression of transport proteins \u2013 ABC (ATP-binding cassette) transporter proteins and multidrug resistant proteins that protect cells against toxins and are associated with the efflux of xenobiotic toxins, low rate of cell division and active DNA repair are the innate properties of normal development of stem cells. Besides hormonal stimulation, DNA damage is one of the key factors for stem cell activation. DNA accumulates errors either from environmental factors, which could be the exposure to radiation, chemicals or drugs, viruses and bacteria or DNA replication errors . This woCancer stem cells (CSCs) were first identified in 1990s in hematological malignancies, mainly acute myelogenous leukemia (AML) and also in other subtypes like AML M0, M1, M2, M4 and M5 and chronic myeloid leukemia (CML), acute lymphoblastic leukemia (ALL) and multiple myeloma . CSCs arIn the hematopoietic and solid tumors side population (SP) containing CSCs constitute the fraction of total population of cells that shows that CSCs is a common phenomenon for all the malignancies. SP can be identified by the efflux of fluorescent dyes by ABC transporter proteins which are the major multidrug resistant genes. In the absence of DNA repair capacity, the drug resistant pluoripotent cells accumulate mutations and show increased cell survival .To maintain the genomic integrity and normal functioning of stem cells, several DNA repair pathways come into interplay and provide the robust defense to the cell. Absence of these repair processes have a great impact on the diminution of stem cells and increased chance for stem cell differentiation and malignant transformation due to altered gene expression.AGT repair is a DNA repair protein encoded by MGMT (O6-methylguanine DNA methyltransferase) removes DNA adducts from O6 methylguanine. The failure in the repair system results in G to A transition and DNA strand break observed in hematopoietic tumors, breast, ovarian and retinoblastomas ,14.In NER, the damaged DNA bases are recognized by XPC (xeroderma pigmentosum complementation group C) and RAD23B whereas XPA, RPA (replication protein A), RNA polymerase II transcription factor 11A and XPG excise the fragment of 27\u201330 nucleotides surrounding the damaged bases. The gap is further restored by DNA polymerases and ligases and replaces it with the correct sequence. Defective NER leads to xeroderma pigmentosum (skin cancer) .It comprises of short and long patch pathways where DNA glycosylases generate apurinic/apyrimidinic (AP) followed by its 5' excision by AP endonucleases (APE-1) and remove damaged bases. Double-stranded breaks have the potential to be the most disruptive form of DNA damage ,17.Double-stranded breaks have the potential to be the most disruptive form of DNA damage. The DNA double strand breaks (DSBs) produced by free radicals generated during oxidative respiration, ionizing radiation, DNA replication, malfunction of recombination activating gene complex during V(D)J recombination in T and B lymphocytes are brought in closed proximity by Ku70-Ku80 heterodimer and kinase activity by DNA dependent protein kinase catalytic subunit (DNA-PKcs) of DNA-PK complex followed by its ligation by XRCC4-DNA ligase IV, SCID (Severe Combined Immunodeficiency) is associated with defective NHEJ repair system .The DSBs are repaired by misalignment, deletions, and rearrangement. ATM, a PI-3 Kinase binds DNA and phosphorylates multiple proteins. BRCA1 activated by ATM (ataxia telangiectasia) facilitates BRCA2 and RAD51 binding of the overhang followed by the attraction of RAD52/RAD54 with the help of BLM/WRN proteins. The homologous recombination is facilitated by large protein complexes at the DSBs. High incidence of leukemia, breast-ovarian, Werner's and Bloom's syndrome with severe premature aging and cancer is seen in defective HR repair system ,19.It is a genome surveillance system in bacteria, yeast and mammals by maintaining genomic integrity. The MMR pathway is the form of DNA repair responsible for the elimination of specific mismatched and/or unmatched bases and insertion-deletion loops (IDLs) where DNA synthesis is liable to errors, either as a part of DNA replication before cell division, or as part of DNA repair (unscheduled DNA synthesis) . AlthougMismatch in eukaryotic DNA is recognized by two heterodimeric complexes of Mut S related proteins \u2013 MSH2/GTBP (Mut S\u03b1) and MSH2/MSH3 (Mut S\u03b2) . Mut S\u03b1 Proliferating cell nuclear antigen (PCNA) has been identified as DNA polymerase processivity factor and has a role in repair at or prior to excision steps as a strand discriminating factor . Bi \u2013 diDNA exonuclease and helicase unwind, nick and degrade the error \u2013 containing strand. After dissociation of MMR complex, PCNA, which still binds at the end of error containing primer strand, recruits replication complex and thus re-initiation starts with the help of DNA polymerase.The mutations characterized by point mutations, insertions or deletions in the length of DNA microsatellite repeat sequences throughout the genome resulting in microsatellite instability (MSI) is a hallmark of defective DNA MMR system which result in malignant transformation .The maintenance of MMR system decreases the error rates by 100 to 1000 fold during DNA replication. Since it has tremendous importance in the carcinogenesis, this review presents a discussion on the role of DNA mismatch repair system as a therapeutic potential in eliminating the cancer stem cells.The maintenance and longevity of stem cell phenotype is characterized by the presence of efficient MMR system, which result in accurate DNA replication, restore normal DNA after its damage and remove replication defects at microsatellite sequences by repairing the DNA polymerase slippage products.-/- and Mlh2-/- phenotype, mice develop stem cell-derived-lymphoid malignancies and all lymphoid tumors show MSI [-/- primary murine hematopoietic cells with wild type into lethally irradiated mice with temozolomide, a methylating agent.

Unlike The mitotic homologous recombination can result in chromosomal translocations, deletions or inversions with deleterious consequences in the adult or during development. Loss of MMR adds up an additional level of genetic instability in a form of chromosomal rearrangements commonly observed in hematological malignancies. High incidence of lymphoma is reported in Msh2 deficient mouse embryonic stem cells .-/- mouse ES cells after exposure to temozolomide but not cisplatin and contributed to failed repair mechanism and apoptosis in a p53 dependent manner [The Msh2 low and deficient mouse ES cells showed poor or complete elimination of repair function and demonstrated the resistance against the toxic effects of an ethylating agent, N-ethyl-N-nitrosourea (ENU).

On the pe cells . Howeverpe cells , increasIn most of the malignancies CSCs constitute less than 1% of total cell population. They are in quiescent state and most of the conventional chemotherapeutic drug therapies are effective in actively dividing cells, so for complete eradication of CSCs, the therapeutic agents either should kill cells independently of the cell cycle or selectively induce cycling of cancer cells. Moreover, therapy should target pathways uniquely used by CSCs. CSCs express various drug transporter proteins which efflux the cytotoxic drugs and protect them from damage. The inhibitors to these transporters make the CSCs sensitive to chemotherapy. Since normal stem cells also express some of these transporters so non selective inhibition of these multidrug resistant genes also kill normal stem cells. The characterization of stem cells markers would help in identification of CSCs from normal stem cells have important implications in elimination of CSCs by specifically targeting the tumor cells . Table 2The wild type MMR expression blocks the homologous recombination between the diverged DNA sequences throughout the genome and thus prevent the stem cell to accumulate further genetic instability. Hematological malignancies and lymphoma arise due to chromosomal rearrangements because of loss of MMR proteins . The effMost of the human cancers are identified having mismatch repair deficiency that result in defect in cell cycle and altered growth as in case of hematological malignancies. The defective MMR status in a damaged cell directly contributes to the resistant phenotype against the cytotoxic effects of chemotherapeutic drugs and thus these CSCs survive chemotherapy Fig . The actThe maintenance of genomic stability is the prime requirement for the stem cell phenotype and its normal functioning. The increased mutation rate and absence of MMR may give rise to stem cell failure, a proliferative advantage and cancer stem cells formation. The cancer stem cells having MMR deficiencies make them insensitive to the treatments against the cytotoxic agents and would increase the risk of relapse and metastasis.

Upregulated MHC class II expression on dysplastic epithelial cells was also found in the different CIN groups and carcinomas. Prevalence of HPV genotypes increased with the severity of the lesion, mainly due to the contribution of the HPV types 16 and 18. No correlation could be established between the presence of specific HPV genotypes and any MHC expression pattern in the different CIN groups or cervical carcinomas.

Using flow cytometric evaluation of equilibrium intracellular levels of daunorubicin (DNR), we found that eight other surface active agents will also reverse MDR. All the active detergents contain polyethoxylated moieties but have no similarities in their hydrophobic components. The properties of three polyethoxylated surfactants that showed the lowest toxicities, Cremophor, Tween 80 and Solutol HS15, were examined in more detail. The concentrations of Tween 80 and Solutol required to reverse DNR exclusion were 10-fold lower than for Cremophor. However while concentrations greater than or equal to 1:10(2) of the former two surfactants resulted in breakdown of cells, even 1:10 of Cremophor did not lyse cells. Studies of the effects of Cremophor on the uptake and efflux of DNR in normal and MDR cell types showed that Cremophor increases intracellular DNR primarily by locking the rapid efflux from the cells. This blockage of drug efflux may be mediated by a substantial alteration in the fluidity of cell membranes induced by Cremophor, as shown by decreased fluorescence anisotropy of a membrane probe.

The hypoxic fraction was calculated from the dose difference between the TCD50S for tumours irradiated either in air or under clamped conditions. The relative survival of tumour cells after drug therapy was expressed as a surviving fraction (SF).

However, the few empirical studies comparing mtDNA and NRY variation and known patterns of sex-biased migration have produced conflicting results. Here we review some methodological reasons for these inconsistencies, and take them into account to provide an unbiased characterization of mtDNA and NRY variation in chimpanzees, one of the few mammalian taxa where males routinely remain in and females typically disperse from their natal groups. We show that patterns of mtDNA and NRY variation are more strongly contrasting in patrilocal chimpanzees compared with patrilocal human societies. The chimpanzee data we present here thus provide a valuable comparative benchmark of the patterns of mtDNA and NRY variation to be expected in a society with extremely female-biased dispersal. Human societies show significant variation in post-marital residence practices. About 70% of human societies practice some form of patrilocality, with men remaining in and women migrating from their natal household, clan, lineage, village, or other cultural unit subsumed within a larger group of people sharing a common culture and language, often termed a `trib\u00e9 in traditional societies One study of Hill tribes of northern Thailand showed the predicted differences between patrilocal and matrilocal tribes in patterns of mtDNA and NRY variation At least three factors may contribute to the discrepant findings of prior research comparing contemporary patterns of genetic variation and post-marital residence practices. First, analyses of mtDNA and NRY variation have been performed at a broader scale of social organization than that at which sex-biased migration actually takes place. For example, the different patterns of mtDNA and NRY diversity shown by matrilocal and patrilocal tribes in Thailand versus India may occur because only in Thailand do members of the migrating sex sometimes move out of their own tribe to join another. Migration outside the tribe is actually a rare event in traditional societies, as different tribes can have very different languages and cultures A second factor complicating attempts to compare patterns of mtDNA and NRY variation is that estimates of genetic differentiation between populations are sensitive to variables that reduce the level of within-group variation, with decreased variation resulting in larger genetic differentiation. For example, an early study of global genetic variation found that genetic differentiation among continents was larger for the NRY than the mtDNA Finally, a third possible reason for the contradictory findings of prior research is that we do not know for how long and how consistently each of the sampled societies has practiced their particular form of post-marital residence. One of the societies in the Central Asian study has practiced its contemporary form of post-marital residence for several centuries In contrast to the complex situation in human populations, patterns of sex-biased migration in animals are often well known from long-term behavioral observations. The currently available genetic studies of animal populations, however, furnish limited insights into how sex differences in migration affect mtDNA and NRY variation. Long-term behavioral observations indicate that migration out of bonobo groups is extremely female-biased Here we examine patterns of mtDNA and NRY variation in four groups of wild chimpanzees located in Uganda and separated by 10\u2013165 km. Chimpanzees live in communities consisting of 20\u2013150 individuals, and as a result of over 180 total years of human observation at multiple field sites, their migration patterns are well understood ST based genetic differentiation estimates, we use the recently developed standardized measure of genetic differentiation We compare the patterns of variation in chimpanzees with those inferred from published data on patrilocal human tribes belonging to five different larger cultural/geographic regions, hereafter termed \u2018tribal groups\u2019 P\u200a=\u200a0.008, two-tailed) . Chimpanzees thus have reduced levels of NRY diversity relative to mtDNA diversity compared with patrilocal humans.We found that the average NRY haplotype diversity of the four chimpanzee communities was significantly lower than that of the 20 patrilocal human tribes . However-tailed) , suggestWe found extensive sharing of mtDNA variants among chimpanzee communities that strongly contrasted with complete community specificity of NRY haplotypes . In contStandardized genetic differentiation produced broadly similar results, with chimpanzees showing significantly larger standardized NRY genetic differentiation than three of five patrilocal human tribal groups . HoweverThe more similar standardized than unstandardized NRY/mtDNA genetic differentiation ratios between chimpanzees and patrilocal human tribal groups suggest that in addition to differences in the extent of female-biased migration, other factors which reduce NRY relative to mtDNA within-group variation have affected chimpanzees more strongly than the patrilocal human tribal groups. One possibility is that the effective population size of males relative to females may be smaller in chimpanzees than it is in humans. To test this hypothesis, we used parentage assignments in the chimpanzee communities and published human data sets to compare sex differences in effective population size in both species. We found that the ratio of male to female variance in lifetime reproductive success (LRS), an important factor influencing sex differences in effective population size, is actually similar in chimpanzees and in humans living in traditional societies . Taken tWhatever the reason for the discrepancy between unstandardized and standardized NRY/mtDNA genetic differentiation ratios, standardized NRY and mtDNA genetic differentiation were still more strongly contrasting in chimpanzees than in patrilocal human tribal groups. This suggests that migration is more female-biased between chimpanzee communities than between patrilocal human tribes within a tribal group. Additional analyses of patrilocal humans which are conducted on the scale over which sex-biased migration actually occurs, e.g., villages within a tribe rather than tribes within a tribal group, will be necessary to test this hypothesis. Alternatively, the recent history of patrilocality in most human populations may have prevented the build-up of such extremely contrasting patterns of mtDNA and NRY variation.

We also analyzed previously published data from five patrilocal Dravidian tribes from India (Vanne (32/23), Pokanati (59/25), Panta (37/21), Kapu (22/16) and Akhutota (32/21)), five patrilocal Mundari tribes from India , Munda (23/23), Kharia (21/13), Bhumij (40/39) and Asur (30/28)), three patrilocal Hill tribes from Thailand (Akha (91/21), Chiang Rae Lisu (53/9) and Mae Hong Son Lisu (42/22)), four patrilocal tribes from the lowlands of Western New Guinea (Awyu (12/10), Citak (40/28), Mappi (18/10) and Muyu (10/6)), and three patrilocal tribes from the highlands of Western New Guinea (Dani (21/12), Ketengeban (22/19) and Una (51/46). Subjects were sequenced at the first hypervariable control region of the mtDNA and genotyped at microsatellite loci on the NRY. The chimpanzees were sequenced at 473 bases and genotyped at 9 microsatellite loci following procedures described elsewhere U tests to compare average mtDNA haplotype diversity, NRY haplotype diversity, and the ratio of NRY/mtDNA haplotype diversity between the chimpanzee communities (N\u200a=\u200a4) and the patrilocal human tribes (N\u200a=\u200a20).We used Arlequin 3.10 Unstandardized genetic differentiation was calculated in an AMOVA framework, with the number of different alleles used as the distance metric for both mtDNA and NRY. We examined the overlap in the 95% confidence limits generated by bootstrapping genetic differentiation values in a locus-by-locus AMOVA to evaluate whether (a) genetic differentiation between the chimpanzees and each of the five patrilocal human tribal groups were significantly different and (b) genetic differentiation of NRY and mtDNA were significantly different within chimpanzees and patrilocal human tribal groups.a and b at a locus, in one of the populations these alleles were recoded as c and d), and calculated an AMOVA FST for this transformed data set . This transformation does not affect within-population variation, but maximizes between-population variation. We then calculated standardized genetic differentiation by dividing the original unstandardized AMOVA FST by the AMOVA FST obtained for this transformed dataset. We included only variable loci when calculating both unstandardized and standardized genetic differentiation. The inclusion or exclusion of non-variable loci does not affect the unstandardized AMOVA, but including non-variable loci when calculating the AMOVA for the transformed data set results in AMOVA values that are determined more by the ratio of variable to non-variable sites, and less by the levels of variability of the variable loci. This would push maximum genetic differentiation possible towards 1, and result in standardized genetic differentiation values that are nearly identical to their unstandardized counterparts. To determine 95% confidence intervals for the standardized genetic differentiation, we divided the lower 95% confidence limit of the original unstandardized genetic differentiation value by the upper 95% confidence limit of the transformed genetic differentiation, and divided the upper 95% confidence limit of the original unstandardized genetic differentiation by the lower 95% confidence limit of the transformed genetic differentiation. For all tests, loci had to have less than 5% missing data to be included in calculations.To calculate standardized genetic differentiation, we first transformed the data such that each population had its own set of unique alleles and females (IF). IM and IF are commonly used to estimate variance in lifetime reproductive success when the sampling of male and female reproductive output is incomplete and the data indicate the sexes have different mean lifetime reproductive success, when in reality they must be equal To estimate variance in lifetime reproductive success, we calculated the variance in the number of offspring divided by the square of the mean number of offspring, for both males Click here for additional data file."} +{"text": "A retrospective analysis was performed of 18 patients with primary malignant germ cell tumours of the mediastinum treated with platinum-based chemotherapy between 1977 and 1990.

On the other hand several chronic fibroproliferative disorders including fibrotic lung diseases are associated with aberrant angiogenesis.

A haThere is increasing evidence supporting the notion that vascular remodeling in fibroproliferative disorders appears to be regulated by an imbalance between angiogenic and angiostatic factors. Seminal observation implicating angiogenic activity as an important aspect of progressive fibrosis was originally made by Turner-Warwick in 1963, when she demonstrated the presence of anastomoses between the systemic and pulmonary microvasculature in lungs of patients with IPF . DespiteKeane and colleagues were the first addressing this crucial issue. They demonstrated increased angiogenic activity in a large number of IPF lung specimens ,42 and sOriginal attempt to prove an association between abnormal vasculature and regional heterogeneity characterizing IPF was performed by Renzoni and coworkers . Fueled Lappi-Blanco et al. addressed this crucial issue ,54. TheyThere is a great lack of knowledge regarding this issue which has been largely ignored. Renzoni et al. were theTowards this direction, Simler et al. performeA second attempt to correlate local and systemic expression of angiogenic mediators with clinical biomarkers of disease severity and activity was recently published by Pignatti et al . They inFinally, Strieter et al. recentlyThe vascular remodeling phenomenon has been also described in the experimental model of bleomycin-induced pulmonary fibrosis. The role of neovascularization during the pathogenesis of experimental pulmonary fibrosis was originally raised by Peao and coworkers . In lineFueled by the prospect that anti-angiogenic treatment could be beneficial for pulmonary fibrosis, Hamada et al. tested tThe latter results have clear therapeutic implications since inhibition of angiogenic mediators or administration of angiostatic chemokines reduced lung collagen deposition and attenuated the exaggerated matrix remodeling. On the basis of this concept, neutralization of proangiogenic environment should be pursued. However, the latter statement should be treated with caution for the following reasons: 1) Findings derived from the bleomycin model of pulmonary fibrosis may not be applicable to human disease since pathogenetic components seen in bleomycin-induced pulmonary fibrosis do not demonstrate areas compatible with fibroblastic foci, the leading edge of human fibrosis. In addition, there are clear limitations to this model in terms of its self-limiting nature, the rapidity of its development and the close association with inflammation that accompanies the lung injury . Regardi2 terminus. While CXCR3/CXCR3 ligands inhibit angiogenesis, CXCR3 ligands play a pivotal role in orchestrating Th1 cytokine-induced cell-mediated immunity via the recruitment of mononuclear and CD4+ T-cells expressing CXCR3 and consequently via the granuloma formation (1). So far, there are only few studies in the literature implicating angiogenesis in the immunomodulatory cascade of sarcoidosis and correlating its immunopathogenesis with members of the angiostatic group of CXC chemokines. These studies are discussed in the following lines.Recent immunological advances on sarcoidosis have revealed a T helper 1 (Th1) and T helper 2 (Th2) paradigm with predominance of the Th1 response in its immunopathogenesis ,68. The The concept of disparate activity of the IFN-\u03b3-induced CXC chemokines in the context of Th1-like immune disorders, such as sarcoidosis, was originally raised by Agostini et al. who docuThe aforementioned studies substantiate the assertion that IFN-\u03b3-induced CXC chemokines are strongly involved in the immunomodulatory cascade of sarcoidosis implicating angiostasis with Th1 immune response. However, there are several arguments that should be addressed. The majority of the studies cited above have investigated the ability of CXCR3 ligands to promote Th1-dependent immunity and not to inhibit angiogenesis. Studies have shown that angiostatic CXC chemokines are more likely to contribute to the granuloma formation through their chemotactic rather than angiostatic properties. The contention of \"immunoangiostasis\" (promotion of Th1 response and at the same time inhibition of angiogenesis) as it has been coined out by Strieter et al. may possIIPs are a heterogeneous group of diffuse parenchymal disorders resulting from damage to the lung parenchyma by varying patterns of inflammation and fibrosis. On the other hand several patients with sarcoidosis develop irreversible lung damage and pulmonary fibrosis which culminates to a fatal outcome. Several theories and mechanisms have been delineated regarding the pathogenesis of fibrotic lung disorders. Recent evidence support the concept that inflammation is subsequent to injury and that fibrosis occurs as a polarization of the Th2 immune response of the body to repeated injury to the lung (\"multiple hits\" hypothesis) ,73.Putting the aforementioned data together, we tentatively present the three current theories regarding the role of aberrant vascular remodeling in the fibrogenic process. The first hypothesis is based on the idea that the hypervascularity observed in the least fibrotic areas has a role in the regeneration of the alveolar septa damaged by the fibrotic process and is a compensatory response to the decreased vascularity seen within the fibroblastic foci Figure . In thisAlternative hypothesis regarding the role of vascular remodeling during the process of ECM remodeling has also emerged. This theory supports the premise that newly formed microvessels enhance the exaggerated and dysregulated ECM deposition, support fibroproliferation and inhibit normal epithelial repair mechanisms . Human ,52 and aThe third theory supports the notion that the role of angiogenesis in the pathologic process of pulmonary fibrosis is overestimated and that aberrant vascular remodeling is just a bystander or a consequence of fibrogenesis. The latter idea is based on the assertion that CXC chemokines may exert their anti-fibrotic activities through pathogenetic pathways different from those of angiogenesis . The afoBased on the above data we can state that although several study groups have investigated aberrant vascular remodeling in the pathogenesis of pulmonary fibrosis, the relative roles played by new vessel formation and vascular regression in IPF and subsequently in other fibrotic lung disorders are still elusive and controversial. However, to address this issue further investigation in the context of large prospective multicenter studies using highly standardized techniques is sorely needed. The emergence of massive genome screening tools (DNA microarrays) coupled Several lines of research have been proven inadequate to demystify the relative role of angiogenesis in the etiopathogenesis of chronic fibroproliferative disorders. The question originally raised still remains unanswered: \"A pathogenetic hallmark of just a bystander?\" However, the status of knowledge regarding the contribution of newly formed vessels in the initiation and/or progression of the sequential events of abnormal injurious response, paradoxical apoptosis and exaggerated matrix remodeling has been greatly elevated by several studies. So far, a number of investigations give credence to the view that a chemokine imbalance favoring angiogenesis supports fibroproliferation and inhibits normal repair mechanisms. Alternatively, the regional vascular heterogeneity in IPF can be explained as a compensatory response (vascular regression) to the striking hypovascularity described in areas of active fibrosis. Currently, angiogenesis represents one of the most fruitful applications in the therapeutic minefield of fibrotic lung disorders. The lack of an effective treatment option challenges chest physicians to think beyond conventional therapeutic strategies and apply fresh approaches. Blockage of multiple angiogenic mediators may provide a way forward.

GCDC increased the growth of the breast cancer cells over the range 10-300 microM. At concentrations in excess of the bile acid binding capacity of the medium cell growth was prevented. In contrast 10 microM CDC tended to reduce cell growth. Oestrogen (ER) and progesterone (PgR) receptors, pS2 and total cathepsin D were quantified by monoclonal antibody based immunoassays. Ten to 100 microM GCDC and 10 microM CDC down-regulated ER protein and this was accompanied by induction of the oestrogen-regulated proteins PgR, pS2 and possibly cathepsin D, including increased secretion of the latter two proteins into the culture medium. All these changes were quantitatively similar to those observed with 10 nM oestradiol. The bile acid effects on ER and PgR were not due to interference with the assay procedures. Cells incubated with 50 microM GCDC or 10 microM CDC had higher pmolar concentrations of the bile acids than controls. This study suggests that naturally occurring bile acids influence the growth and steroid receptor function of human breast cancer cells."} +{"text": "Somatostatin (SMS), a naturally occurring peptide is known to inhibit the production of certain protein molecules and to diminish the ability of peripheral blood mononuclear cells to proliferate. We tested the effects of three forms of SMS on the bioactivity of both lymphotoxin (LT) and tumour necrosis factor (TNF). We also tested the effects of these agents on production of cytotoxins by peripheral blood mononuclear cells. We found the 28 amino acid form of SMS significantly enhanced the bioactivity of both LT and TNF (10(-9) M concentration) when tested in mouse L cells. The 14 amino acid form of SMS enhanced LT (10(-9) M concentration) activity but not TNF activity. The first 14 amino acid form of SMS-28 did not affect bioactivity of the cytotoxin. In contrast, the naturally occurring 14 amino acid form of SMS (10(-8) M concentration) significantly diminished production of cytotoxin by human peripheral blood mononuclear cells. Cytotoxin produced by the latter was shown to be a combination of both LT and TNF. Similarly after SMS exposure, the cytotoxin produced remained a mixture of LT and TNF in roughly similar proportions. It thus appears that certain forms of SMS can enhance the bioactivity of cytotoxins, but at the same time decrease the production of these cytotoxins."} +{"text": "Alterations in the p53 gene were analysed in 39 patients with locally advanced breast cancers (LABCs) (stage III-IV) with inflammatory signs in most cases (UICC stage T4d = 32 patients) by molecular and immunohistochemical (IHC) approaches. All patients were included in the same therapy protocol. Using polymerase chain reaction (PCR) and a single-strand conformational polymorphism migration technique (SSCP), the presence of mutations in exons 2-11, covering the entire coding sequence of the p53 gene, was evaluated. Using the mouse specific anti-human p53 monoclonal antibody (PAb 1801), we also looked for overexpression of the p53 protein in tissue sections. In 16 cases shifted bands were reproducibly identified by PCR-SSCP, and all but one were in exons 5-8, the usual mutational hotspots. Fifteen of these 16 samples were sequenced and 14 of the suspected mutations (36%) were confirmed. Most of them (12) were single nucleotide substitutions, and transitions were more frequent (eight cases) than transversions (four cases). Fourteen of the tumour samples were positively stained with the monoclonal antibody PAb 1801, 11 with nuclear staining only, two with mixed cytoplasmic and nuclear staining and one with cytoplasmic staining only. Staining patterns were very heterogeneous in terms of the percentage of positive cells (10-75%) and their distribution in the tissue section (isolated foci or dispersed cells). In 11 of the 14 mutated cases a positive immunostaining was observed. The presence of a p53 mutation was significantly associated with larger tumour diameter and the presence of clinical metastases (stage IV) . A non-statistically significant trend of association was observed between p53 mutation, negative oestrogen receptors and lower response rate to therapy. Our results in this group of patients and the heterogeneity of the staining of tumour cells in tissue sections suggest that p53 mutations could be a late event in this non-familial form of breast cancer."} +{"text": "We have investigated the capability of differentiation of Ewing's sarcoma (ES) towards a neuronal direction through the establishment of four extraosseous ES cell lines and by in vitro stimulation with dibutyryladenosine cyclic monophosphate (db-cAMP) of eight ES lines.

Two ES lines expressed a 200 kilodalton (kD) neurofilament protein (NFP) although their original tumours were negative for NFP. Elongation of cytoplasmic processes and increased NFP expression were observed after db-cAMP treatment of these lines and microtubules in the cytoplasmic processes were ultrastructurally demonstrated.

There was a higher percentage of low NK responders in patients with lymphocyte depletion histologic grade of the disease and those who were in clinical stage IV, suggesting a correlation of decrease in NK activity with poor prognosis. We found efficient LAK activity against the NK-sensitive K562 cells and NK-resistant VIP (melanoma) and T-24 (bladder carcinoma) tumour targets in both low and normal NK responder HD patients, irrespective of the histopathological grade and clinical stage of the disease.

Following in vivo IUDR labelling, dual parameter flow cytometry was used to measure tumour DNA index (DI) and labelling index (LI) and to derive DNA synthesis time (Ts) and potential doubling time (Tpot). Heterogeneity was seen for all parameters under investigation. Overall coefficients of variation (CV) and logarithmic transformation of Ts and Tpot (due to their non-gaussian distributions) indicate that LI (CV 25%) was the most variable parameter. Intra-tumoral heterogeneity in Tpot (lnTpot CV = 22%) was less than inter-individual variation (CV = 63%), suggesting that this variation should not be a limitation to the possible usefulness of this technique as an independent prognostic indicator. Correlations of Tpot values were examined between the shortest, the median and the value for a pooled homogenate sample from a single tumour. Using an homogenate, it was possible to accurately predict classification of tumour Tpot values as being below the median ('fast tumours') in 15 of 19 cases (79%).

Class I antigens (detected by the McAb 2A1) were consistently associated with stromal leucocytes, fibroblasts and vascular endothelium, but expression on epithelial cells particularly of malignant provenance, was more variable. Class II antigens (detected by TDR 31.1) were present upon a variety of cell types which also included sporadic expression on malignant and benign epithelia. The distribution of leucocytes grossly monitored with 2D1 (reactive with a common leucocyte antigen) was largely interepithelial and periductal in benign lesions. Leucocytes were generally more numerous in malignant tumours, where they were largely confined to the stroma. The majority (approximately 75%) of leucocytes were T lymphocytes (reactive with UCHT1), some of which appeared to react with TDR 31.1 and were therefore activated. Ratios of helper/inducer (OKT4+) and suppressor/cytotoxic (OKT8+) subsets generally exceeded unity in malignant neoplasms. There was no correlation between the extent and distribution of T cells and the HLA status of the epithelial cells. Leucocytes detected by the monoclonal antibody OKM1 which reacts with monocytes/macrophages, granulocytes and large granular lymphocytes were numerically few and again mainly confined to the stroma. In a limited number of tests, leucocytes detected with HNKl, reactive with a differentiation antigen expressed on some cells which mediate natural and antibody-dependent cellular cytotoxicity in vitro although detectable interepithelially in benign tumours, were virtually absent from malignant tissue.

Conventional light microscopy, cytology and electron microscopy examination of the xenografts revealed appearances consistent with SCC. An antikeratin antibody demonstrated the presence of keratin in the inherent and the induced resistant xenografts (and in the unstable revertant) but not in the two sensitive xenografts; the presence of keratin suggested squamous differentiation. Monolayer culture morphology of the sensitive HX78 and the unstable revertant was anchorage independent with the cells forming floating aggregates; the induced resistant subline of this xenograft (HX78Cy) showed, by contrast, flattened, angular adherent cells. Beta HCG production was detected in the monolayer culture supernatant of sensitive HX78 cells; the level of production of beta HCG was increased in the induced resistant HX78Cy cells.

Results: Subjects with Hashimoto disease showed higher frequencies of lifetime Depressive Episode , Generalized Anxiety Disorders and Social Phobia whilst no differences were found between subjects with goitre and controls.The study seems to confirm that risk for depressive disorders in subjects with thyroiditis is independent of the thyroid function detected by routine tests and indicates that not only mood but also anxiety disorders may be associated with Hashimoto disease. Clinical and epidemiological studies seem to indicate that an association between high levels of thyroid autoantibodies may be implicated in the increased frequencies of mood disorders observed in thyroid disease, independently of impairment of thyroid function -3. A stuThe aim of the present study was to compare 2 clinical samples of subjects, one with Hashimoto disease (in euthyroid phase) and the second with euthyroid goitre versus controls drown from a community sample, in order to clarify whether the association of mood and anxiety disorder in Hashimoto disease is evident prior to impairment of thyroid dysfunction.Cases: 19 subjects, 18 females, mean age 39.7+/-12.6, with Hashimoto disease in euthyroid phase and 19 subjects, 16 females, mean age 38.1+/-10.4, with euthyroid goitre, all of whom were attending the Endocrinological Unit of the Department of Internal Medicine, University of Cagliari, Italy.Two control groups, each of 76 subjects aged 18\u201364 years, were obtained by matching each \"case\" with four \"controls\" randomly selected on the basis of demographic characteristics (sex and age) from the data base of a larger population enrolled during a previous epidemiological study aimed at defining the prevalence of psychiatric and thyrTwo standardized forms were used to acquire information concerning: demographic data, state of health and use of social and health services.

No differences were found in the evaluation of lifetime prevalence of DSM-IV Psychiatric Disorders between patients with Euthyroid goitre and controls (Table 1).This study seems to indicate an association between the presence of a lifetime diagnosis of mood or anxiety disorder and Hashimoto disease without functional thyroid impairment. No difference was observed in mood and anxiety disorders between goitre cases and controls.These findings are congruent with the results of a previous study that indThe above-cited community survey found that subjects with at least one lifetime diagnosis of anxiety disorders presented anti-TPO+ more frequently than subjects without mood or anxiety disorders. However, no specific anxiety diagnosis was found to be associated with anti-TPO+, although General Anxiety Disorder showed a strong trend toward association (P < 0.058). Anxiety Disorder Not Otherwise Specified was more frequently observed with anti-TPO+, but this is only a sub-threshold condition. A previous research carried out on celiac patients indicated thyroid autoimmunity as possible risk factor for panic disorder . In the Indeed, these 3 surveys seem to indicate a congruent trend of possible risk for anxiety disorders such Generalized Anxiety Disorder, Social Phobia and Panic Disorder in Hashimoto Disease.To our knowledge, the data concerning the association between sleep disorders and Hashimoto disease is the first such evidence published in literature, although it may be consistent with a dysregulation of sleep architecture in subjects with sub-clinical thyroid impairment .A sub-clinical dysfunction of axis thyrotropin releasing hormone (TRH) thyroid stimulating hormone (TSH) with consequent alteration of circadian rhythms of TSH has been hypothesized in several depressive disorders. Indeed, this hypothesis may explain why some forms of mood disorders were associated with anti-TPO+ without hypothyroidism, as defined by blood routine tests. A slight reduction in thyroid hormone secretion such as that found in sub-clinical hypothyroidism may affect cognition and mood . At variAlternatively, autoimmunity may be implicated in some form of extra-thyroid disease associated (even indirectly) with the depressive symptomatology.In Hashimoto disease the onset of vasculitis is frequently observed and would seem to be directly correlated to the duration of the illness .In this disease brain perfusion modifications would appear to be of an aspecific nature; recently however, Spect examination revealed a marked compromising of the left cingulum posterioris, thus related in the etiology of associated affective disorders .Recent evidence suggests that thyroid autoimmunity may be affected by the Hypothalamic-pituitary-adrenal axis (HPA) through the balance of proinflammatory and antiinflammatory cytokines ,16. In lThe potential of this study is limited by the small sample size, particularly regard to psychiatric diagnoses less frequently observed in the general population, such as Panic Disorder; the extension of the findings is therefore rather limited.This study seems to indicate an association between the presence of a lifetime diagnosis of mood or anxiety disorder and sleep disturbance and anti-TPO+. The findings obtained suggest the need for further longitudinal studies aimed at clarifying the association between anxiety and depressive disorders and anti-TPO+."} +{"text": "The prognostic role of drug-induced amenorrhea (DIA) was restrospectively evaluated in 221 out of 254 consecutive premenopausal patients treated with adjuvant CMF or a CMF-containing regimen; 33 patients were eliminated because of lack of menstrual data. All patients had metastatic axillary nodes; drug regimens were: CMF x 9 courses +/- Tamoxifen (TM) and CMF x 6 courses; median age was 43 (range 26-54). Premenopausal status was defined as last normal menses within the 6 weeks preceding initiation of chemotherapy: DIA as cessation of menses for at least 3 months not later than 3 months from the end of chemotherapy. DIA occurred in 166,221 (75.1%) patients and was strictly related to the age of the patients; also, the older the patients the shorter the time required to develop DIA. At median follow up of 69 months, Mantel-Byar analysis showed a longer disease free survival (DFS) for patients who developed DIA as compared with non amenorrheic women (P less than 0.001). DIA prognostic value was independent of age, number of involved nodes, tumour size and number of CMF cycles, as assessed by the Cox model , in which DIA was entered as a time dependent covariate."} +{"text": "Nuclear deoxyribonucleic acid (DNA) content of hepatocellular carcinoma (HCC) in 41 South African and 47 Japanese patients at autopsy was analysed by dual-wavelength microspectrophotometry. The DNA distribution patterns were classified as type I, II, III or IV and as low ploidy or high ploidy , according to the degree of dispersion. We found a significantly higher incidence of high ploidy in South African HCC than in Japanese HCC. Moreover, type IV was significantly more frequent among South Africans than among the Japanese. These findings demonstrate that large differences in biological characteristics and clinical behaviour of HCC between South Africa and Japan may reflect differences in DNA distribution patterns which we observed between these two races."} +{"text": "The cell kinetics of 82 squamous cell carcinomas of the head and neck were studied by in vivo administration of the thymidine analogue, bromodeoxyuridine (BrdUrd). Ploidy, BrdUrd labelling index (LI), duration of S-phase (Ts), potential doubling time (Tpot) and S-phase fraction (SPF) were measured by flow cytometry on 50 microns paraffin embedded sections. The range of values obtained compared well with other in vivo cell kinetic studies of head and neck cancer. Aneuploid tumours had a significantly higher BrdUrd labelling index and SPF, and a short Tpot than diploid tumours. To validate the use of 50 microns sections for measuring cell kinetic parameters by flow cytometry a comparison of values obtained by 50 microns sections and small blocks of tissue was made. No significant difference was found between the two methods. Reproducibility of values between two consecutive thick sections was also good. We conclude that reproducible cell kinetic measurements can be made in tumour samples using 50 microns sections of BrdUrd labelled tissue."} +{"text": "This study was designed to compare two different modalities of TBI which are currently used in clinical practice. The same dose of 750 cGy was given to CBA mice either in a single dose at a low dose rate (4 cGy min-1) (STBI) or in a fractionated regimen (six fractions of 125 cGy three times a day) at a higher dose rate (25 cGy min-1) (FTBI). After TBI completion we simultaneously studied the in vivo radiation response of bone marrow cells, two murine bone marrow clonogenic cells (CFU-S and GM-CFC) and peripheral blood lymphocytes and granulocytes for a period of 1 month. The percentage of spleen erythrocytic and granulocytic colonies was also determined. No significant differences were observed between the two groups in the first 48 hours after irradiation except in bone marrow cell numbers, probably due to differences in the overall treatment time between the two TBI schedules. After the first 48 hours the repopulation patterns of the different cells were very similar in both groups. These findings suggest that the different dose rates and fractionation used in this study caused similar radiation damage to the murine haemopoietic system. Moreover, no significant repopulation occurred during the longer overall treatment time of the fractionated regimen. These preliminary results must be corroborated with a larger range of doses before any firm conclusion can be drawn."} +{"text": "Nine primary pulmonary carcinomas, one metastatic carcinoma, and two malignant pleural mesotheliomas have been analysed for the expression at the mRNA level of metalloproteinases (MPs) and tissue inhibitors of MPs (TIMPs). In situ hybridisation showed TIMP-1 and TIMP-2 transcripts predominantly over tumour stroma and gelatinases evenly distributed over both stromal and tumour cells. While both TIMP-1 and TIMP-2 were expressed in non-neoplastic lungs (NNL) as well as in carcinomas, stromelysin 3 (ST3), 92 kDa gelatinase and interstitial collagenase were expressed only by carcinomas. Expression of these MPs by carcinomas was independent of histologic type and such tumour features as fibrosis or necrosis. The consistent expression of ST3 by all of the carcinomas examined and absence of its expression in NNL indicates that ST3 production is likely associated with the malignant phenotype. However, since 92 kDa gelatinase and interstitial collagenase transcripts were found in some but not all tumour samples, their expression is not a uniform feature of pulmonary carcinomas. The possible prognostic significance of the expression of the latter two enzymes by carcinomas remains to be established."} +{"text": "Antigenic modulation of major histocompatibility and tumour associated antigens was observed in neoplastic cells obtained from patients with pleural and abdominal effusions of breast and ovary carcinomas following a single intracavitary dose of 18 x 10(6) U recombinant IFN-alpha. This regimen resulted in antigenic modulation in seven out of 11 tested cases, suggesting a potential, although limited, responsiveness of at least a fraction of breast and ovary carcinoma cells to in situ biomodification with IFN-alpha."} +{"text": "Drug resistance in haemopoietic cells may be partly related to the expression of the glutathione-s-transferase (GST) pi and mdr-1 genes. We have used RNA slot blotting techniques to investigate the expression of GST pi in peripheral blood and bone marrow of eleven normal subjects, nine patients with myelodysplastic syndrome (MDS), eighteen patients with acute myeloblastic leukaemia (AML), and thirty-two patients with chronic lymphocyte leukaemia (CLL). We found increased expression of GST pi in 8 of 9 MDS, 12 of 18 AML and in the peripheral blood of 24 of 32 CLL relative to normal controls. Increased expression of GST pi can occur at any stage of disease and shows no clear relation to mdr-1 expression except, possibly, in CLL. In 3 AML patients GST pi transcript levels were the same or lower on relapse compared to presentation. Upregulation of the GST pi gene could not be demonstrated in 2 CLL patients in response to treatment with intermittent chlorambucil."} +{"text": "The QR regressor tumour (QR-32), a fibrosarcoma which is unable to grow progressively in normal syngeneic C57BL/6 mice, was able to grow progressively in 13 out of 22 mice (59%) when it was subcutaneously coimplanted with gelatin sponge. We established four culture tumour lines from the resultant tumours (QRsP tumour lines). These QRsP tumour lines were able to grow progressively in mice even in the absence of gelatin sponge. The ability of QRsP tumour cells to colonise the lungs after intravenous injection and to produce high amounts of prostaglandin E2 (PGE2) during in vitro cell culture was much greater than that of parent QR-32 cells. These biological characteristics of QR-32 cells and QRsP tumour cells were found to be stable for at least 6 months when they were maintained in culture. We also observed that QR-32 cells were able to grow progressively in five out of 12 (42%) mice after coimplantation with plastic non-adherent peritoneal cells obtained from mice which had been intraperitoneally implanted with gelatin sponge. These host cells reactive to gelatin sponge increased the production of high amounts of PGE2 by QR-32 cells during 48 h coculture. Preliminary in vitro studies implicated the involvement of hydrogen peroxide and hydroxyl radical as some of the factors necessary to induce QR-32 cells to produce high amounts of PGE2 and to accelerate tumour progression."} +{"text": "We have found that elevation of preoperative serum sialyl-Tn antigen (STN) levels is associated with a poor prognosis for gastric cancer patients, and these high levels remain in the advanced stage of the disease. We have now examined findings with the combined assay of STN and carcinoembryonic antigen (CEA) levels with regard to prediction of the prognosis of gastric cancer patients. Serum CEA levels and STN levels were determined preoperatively in 349 Japanese patients with gastric cancer. The patients were divided into four groups: (A) the CEA (-) STN (-) group ; (B) the CEA (-) STN (+) group ; (C) the CEA (+) STN (-) group ; and (D) the CEA (+) STN (+) group . Clinicopathological features and the prognosis of these groups were examined. The distribution of two markers showed no significant correlation. The patients in the CEA (+) STN (+) group (group D) had more advanced disease than the patients in CEA (-) STN (-) group (group A); tumour size was larger, serosal invasion was prominent, lymphatic and vascular involvement was frequent and the tumour was more infiltrative. Lymph node metastasis and hepatic metastasis were more common. Total gastrectomy was usually performed, and the non-curative rate was higher. The 5-year survival of patients in the CEA (+) STN (+) (group D) was 14.5 +/- 9.5%, that is lower than that of patients in any other group . This combined assay of these markers will aid in estimating the prognosis and selecting appropriate drugs and care for gastric cancer patients."} +{"text": "Growth in soft-agar bilayer cultures of human tumour cells derived from 4 in vitro continuous cell lines, from 21 xenografts carried in athymic mice, and from 197 samples of fresh human solid tumours of various histologic types was analyzed by computer-assisted image analysis. Replicate cultures for each specimen were assessed on successive days of incubation for the number and volume of growth units within multiple size categories. Our results confirm the recent finding of others that there is an upper limit of approximately 10(9) microns 3 to the cumulative growth unit volume obtainable in a 2 ml bilayer soft agar culture system. Since this upper limit to the carrying capacity of the closed culture system exists, the extent of growth within the cultures is determined in a fundamental way by the cumulative volume of growth units initially inoculated into cultures. A growth index of greater than or equal to 16-fold was only seen when initial cumulative growth unit volume was less than 10(7) microns 3 per culture dish. Computer-assisted volume analysis (CAVA) appears to be a useful quantitative method to study the growth of human tumour cells in soft agar cultures."} +{"text": "As yet, there is no reported study of chromosome allele loss in fibrolamellar carcinoma (FLC), a distinct, rare variant of hepatocellular carcinoma (HCC). We searched for evidence of allele loss in FLC using 18 DNA probes for 10 chromosomes and compared the pattern of loss with our series of HCC. Two of the probes, lambda MS32 (1q42-43) and cMS621 (5p) showed allele losses in one tumour, while other probes showed no loss. The frequency of allele loss in FLC was much lower than in HCC, which may be associated with their different prognoses."} +{"text": "Two hundred and twenty-two women with advanced cancer of the breast were asked to complete two previously validated self-assessment questionnaires and the Rotterdam Symptom Checklist (RSCL) in order to determine the prevalence and persistence of affective disorders in this group of patients. Fifty-six (27%) of 211 women who completed the HADS and 33 (22%) of 204 who completed the RSCL rated as probable cases of an anxiety state and/or depressive illness. One hundred and fifty-five patients completed the questionnaires again 1-3 months later. Twenty-one (13%) were persistently anxious or depressed as judged by the HADS compared with 14 (10%) on the RSCL. When both questionnaires were considered together, approximately one third of patients had scores suggestive of an affective disorder and in one third of these it was persistent. Only 30 patients (43% of cases) were detected as 'cases' by both questionnaires and this finding warrants further investigation."} +{"text": "Transcriptome data from quantitative PCR (Q-PCR) and DNA microarrays are typically obtained from a fixed amount of RNA collected per sample. Therefore, variations in tissue cellularity and RNA yield across samples in an experimental series compromise accurate determination of the absolute level of each mRNA species per cell in any sample. Since mRNAs are copied from genomic DNA, the simplest way to express mRNA level would be as copy number per template DNA, or more practically, as copy number per cell.Here we report a method (designated the \"Percellome\" method) for normalizing the expression of mRNA values in biological samples. It provides a \"per cell\" readout in mRNA copy number and is applicable to both quantitative PCR (Q-PCR) and DNA microarray studies. The genomic DNA content of each sample homogenate was measured from a small aliquot to derive the number of cells in the sample. A cocktail of five external spike RNAs admixed in a dose-graded manner was prepared and added to each homogenate in proportion to its DNA content. In this way, the spike mRNAs represented absolute copy numbers per cell in the sample. The signals from the five spike mRNAs were used as a dose-response standard curve for each sample, enabling us to convert all the signals measured to copy numbers per cell in an expression profile-independent manner. A series of samples was measured by Q-PCR and Affymetrix GeneChip microarrays using this Percellome method, and the results showed up to 90 % concordance.Percellome data can be compared directly among samples and among different studies, and between different platforms, without further normalization. Therefore, \"percellome\" normalization can serve as a standard method for exchanging and comparing data across different platforms and among different laboratories. E. coli.

Sections from each tumour were stained with haematoxylin and eosin (H & E) and immunocytochemically for HCG. In 33 (14.5%) of the tumours HCG-containing cells were observed, but in only 12 were these recognised in an initial study of the H & E stained sections. HCG staining was seen predominantly in syncytiotrophoblastic giant cells and rarely in \"mulberry\" cells and mononuclear seminoma cells. Of the patients whose tumours included HCG-containing cells 23% died of their disease within 2 years of orchidectomy, compared with only 8% of the patients whose tumours lacked this feature. It is concluded that immunocytochemical staining for HCG should form part of the routine histological assessment of seminomas, and that the presence of HCG-containing cells indicates a more aggressive disease."} +{"text": "An analysis of the primary tumour histopathology was performed on 103 patients managed by orchidectomy and surveillance for stage I seminoma. Patients have been followed for 14-141 months (median 62 months) after orchidectomy. Seventeen patients relapsed, the probability of remaining relapse free at 5 years being 82% . No patients died of progressive germ cell tumours. The only significant histological factor predicting relapse was the presence of lymphatic and vascular invasion. Four of 42 patients with neither lymphatic or vascular invasion recurred, nine of 53 patients with either lymphatic or vascular invasion recurred and three of eight cases with both lymphatic and vascular invasion recurred (P = 0.05-trend). Though initial recurrence was usually of moderate volume and confined to para-aortic nodes, eight patients were treated with chemotherapy either because of the extent of their initial relapse (four cases), or because of subsequent relapse (four cases). In view of the difficulties of identifying patients at risk and of detecting early relapse, surveillance for stage I seminoma should remain a research protocol."} +{"text": "The \"Sir Charles Bell Society (SCBS)\" is an inThe SCBS began as an informal group in 1992 during the VIIth International Facial Nerve Symposium in Cologne. At this initial meeting, 74 attendees confirmed the need for a multinational approach. The original 74 attendees were to be considered as \"Founding Members\" and they drafted a Statement of Purpose: \"The SCBS is to be an international forum for clinicians of all medical specialties and researchers in basic or clinical science who have a special interest in the facial nerve and its disorders. This unique international multi-disciplinary organization is dedicated to the collection, dissemination and exchange of ideas relating to the facial nerve and its diseases.\" Their first charge was to aid Professor Naoki Yanagihara in organizing the \"VIIIth International Facial Nerve Symposium\" to be held in Japan in 1997.The SCBS was officially recognized June 23, 1993, incorporated in the state of California as a non-profit mutual benefit corporation organized under the non-profit mutual benefit corporation law meeting the criteria of: Internal Revenue Code Section 501 C (6) with FEDERAL Employee Identification Number: 94-320802 and California Corporate Number; 1917755 SCOBS.Membership includes otolaryngologists, plastic-reconstructive surgeons, neurologists, neurosurgeons, basic science researchers, physiotherapists, audiologists, anatomists, psychologists, psychiatrists, radiologists, and internists. At present there are over 229 members from 32 countries.The scientific impact is based on the interdisciplinary discussion of problems dealing with the facial nerve. An international meeting is held every four years in different countries. Main topics of discussion and international exchange are:\u25b6 Facial nerve regeneration following different kind of lesions\u25b6 Changes of the Central Nervous System following different kind of nerve lesions\u25b6 Surgical and conservative methods for treatment of facial nerve diseases\u25b6 Evaluation of grading systems.An important aspect of the SCBS is that these problems are discussed on an interdisciplinary platform.The last meeting of the SCBS was held in 2005 in Maastricht/Netherlands during the \"Xth International Facial Nerve Symposium (Chairman: Hans Manni)\" with election of Rainer Laskawi (Germany), President; Jacqueline Diels (USA), Secretary; Paul Mulkens (Netherlands), Treasurer, Mihael Podvinec (Switzerland) is Webmaster and Kedar Adour (USA) President-Emeritus.

The IRMA detected immunoreactive PLAP in 37 of 80 (46%) human epithelial and germ cell cultures, while the IAEA detected PLAP in only 25 (33%). Of the 52 non-germ cell tumour cultures, the IRMA detected expression in 24 (46%) and the IAEA in only 16 (31%). In 17 cases (21%) the IRMA recorded levels double that of the IAEA, while in five cultures (6%) the reverse was true. The IRMA was much more robust than the IAEA and had considerably lower inter- and intra-assay coefficients of variation (3.75-8.5% vs 5.2-46%). Detection of PLAP(-like) expression by IAEA is dependent on neoplastic expression of enzymatically functional molecules and quantification assumes constant enzyme kinetics. PLAP-like material has a higher catalytic rate constant than PLAP and thus will give higher values on a stoichiometric basis in an IAEA. The higher detection rate and levels of PLAP-like material in neoplastic cultures when measured by the IRMA clearly demonstrate ectopic expression of non-enzymatic PLAP and PLAP-like genes. The incidence of PLAP(-like) expression by non-germ cell and possible germ cell tumours has been underestimated and its utility as a tumour marker should be re-examined using assays which measure antigen mass rather than phosphatase activity."} +{"text": "Inconsistent findings on the efficacy of psychosocial interventions in cancer may be due to their lack of specificity. The aim of this study was to identify priorities of psychosocial need among cancer patients currently receiving treatment in Western Sydney (NSW) as a prelude to targeted intervention. A sample of 188 patients , with various solid tumours, completed a self-report ranking questionnaire listing eight major areas of psychosocial need based on a literature search of relevant studies. The resulting ranking of priorities was: family (1), dealing with emotional stress (2), getting information (3), money (4), work (5), social life (6), sex life (7), and dealing with hospital staff (8). These priorities were independent of demographic characteristics, including time since diagnosis, suggesting that support in the areas of major need may be just as important during follow-up as it is at diagnosis. Males reported less distress than females, and patients with cancer of the head/neck or breast reported most distress. To be maximally effective, psychosocial intervention for cancer patients should focus on the principal areas of family interaction, effective stress management, and access to information."} +{"text": "Helix pomatia agglutinin (HPA)- and Concanavalin A (Con A)-binding carbohydrate expression were studied on 32 tumour samples from primary adenocarcinoma of the breast and 12 samples from lymph node metastases. Live cells were spilled from each of the fresh samples and the extent of fluorescent-labelled HPA and Con A-binding was assessed by flow cytometry. The extent of brightness was expressed in a defined quantitative fashion and the percentage of positive cells was accurately determined from a sample of 10,000 cells per tumour. Correlation of binding with clinicopathological features showed that HPA but not Con A related to lymph node involvement (P = 0.001) in tumours of higher grade (II and III). Spilled tumour cells (non-lymphocytes) were selected from the lymph nodes and the presence of HPA binding cells in the involved lymph nodes was found to relate to positive HPA binding in autologous primary tumours (P = 0.002). Dual-label analysis of HPA and Con A binding showed characteristic features for each tumour. The study demonstrates the use of flow cytometry as a simple and effective technique in detecting differences in lectin binding in live spilled cells from fresh breast cancer tissues. This method may prove to be particularly useful if performed preoperatively on cells in fine-needle aspirates."} +{"text": "The present investigation shows the effect of vitamin A deficiency on the initiation and postinitiation phases of benzo(a)pyrene-induced lung carcinogenesis in male Wistar rats. Lung tumours were induced by giving three intratracheal instillations, one week apart, of 10 mg benzo(a)pyrene per instillation. Maximum tumour incidence (100%) and tumour burden per rat was found in rats which were kept on vitamin A deficient diet for 4 weeks prior to the first administration and 8 weeks after the last administration of benzo(a)pyrene. Rats in which vitamin A deficiency was terminated after the last administration of the carcinogen had 83% tumour incidence, whereas corresponding control pairfed animals had 39% incidence of tumours. These data represent the values obtained 32 weeks after the last administered dose of the carcinogen and indicate the role of vitamin A, both in the initiation as well as in the postinitiation phases of lung carcinogenesis."} +{"text": "The clinical significance of neuron-specific enolase (NSE) as a tumour marker was evaluated in 54 patients with seminoma. Before orchiectomy NSE was elevated in six out of 21 patients with stage I seminoma and 11 out of 16 patients with metastases. After orchiectomy NSE normalised in all evaluated stage I cases, but was still elevated in six out of 12 patients with metastatic disease. NSE monitored the effect of cisplatin-based chemotherapy in patients with metastases. In some patients, increased serum NSE was found together with raised levels of human choriogonadotropin (HCG) and lactate dehydrogenase (LDH), while in others only NSE was elevated. No false positive NSE values were observed. NSE seems to be a clinically worthwhile serum tumour marker for monitoring seminoma patients, with a sensitivity and specificity of the same order as HCG."} +{"text": "Pancreatic ductal adenocarcinomas are characterised by a dense connective tissue reaction. To test the hypothesis that stroma components are synthesised and produced by the tumour cells themselves, eight cell lines as well as six xenografted tumours from human ductal adenocarcinomas of the pancreas were examined for the expression of extracellular matrix proteins (ECM), using cDNA probes and antibodies to collagen types I, III and IV, vitronectin, fibronectin, undulin and laminin. All tumour cell lines and xenografted human pancreatic tumours expressed at least one of the examined ECM at the RNA (collagen type IV > laminin = fibronectin = vitronectin > collagen type III > undulin > collagen type I) or protein level (collagen type IV = collagen type III > vitronectin > laminin > collagen type I = fibronectin > undulin). In nude mouse tumours expression of laminin and collagen I was most pronounced in well-differentiated carcinomas. In a few tumours, collagen type III, vitronectin and undulin were expressed on the luminal side of the neoplastic glands, suggesting loss of normal polar differentiation. Incubation with fetal calf serum modulated ECM RNA levels to a varying extent in all but one cell line (AsPC-1). The results suggest that human pancreatic ductal adenocarcinomas cells are capable of synthesising and producing extracellular matrix proteins in vitro and in vivo, but that the extent and pattern of ECM expression differs between the various tumours and conditions tested."} +{"text": "Serum levels of TAG 72 were measured in 726 serum samples from patients with benign and malignant gynaecological conditions in order to evaluate the clinical usefulness of TAG 72 alone or in combination with other tumour markers. Sixty-six per cent of patients with ovarian cancer showed abnormal concentrations of TAG 72 antigen. A good correlation was also found between serial TAG 72 values and the clinical course of disease during chemotherapy and follow-up. In cervical and endometrial cancer abnormal TAG 72 values occurred in 23% and 14% of cases, while none of the patients with breast cancer had abnormal TAG 72 levels. Among patients with benign disease only one out of 12 patients (8%) with benign ovarian tumours and one of 15 patients with uterine fibromyomatosis (7%) showed high TAG 72 serum levels. However, the determination of TAG 72 did not increase the sensitivity of CA 125 and squamous cell carcinoma antigen (SCC), in ovarian and cervical cancer, respectively. The systemic administration of recombinant interferon alpha-2b to 15 patients with ovarian cancer and different basal levels of TAG 72 did not increase serum levels of the antigen."} +{"text": "Serial image guided 31P magnetic resonance spectroscopy (MRS) studies were performed in eight patients with non-Hodgkin's lymphoma to determine the changes in phosphorus metabolites that occur in vivo in response to chemotherapy. Pre-treatment spectral characteristics were different in high and low grade lymphoma. A larger inorganic phosphate (Pi) peak was seen in high grade NHL relative to phosphomonoesters (PME) or beta adenosine triphosphate (beta ATP), producing significant differences in the PME/Pi and Pi/beta ATP metabolite ratios, and probably reflecting a larger hypoxic cell fraction within the high grade lymphomas. Consistent metabolite changes were seen with treatment, and before reductions in tumour bulk had occurred. Alterations in tumour energetics with changes in Pi and beta ATP, and increases in phospholipid turnover reflected as an increase in the phosphodiester (PDE) resonance were detected. Changes were seen between days 10 and 27 in low grade lymphoma treated with oral alkylating therapy and between days 1 and 5 in lymphoma treated with intensive combination chemotherapy. Increases in the PDE/beta ATP metabolite ratio may be an early indicator of response to chemotherapy in human tumours. These studies illustrate the feasibility and clinical potential of image guided 31P MRS as a means of assessing response to therapy."} +{"text": "Sequential methotrexate (Mtx) absorption studies were undertaken in 127 children undergoing treatment for childhood non-T acute lymphoblastic leukaemia (ALL) to determine whether serum drug concentration, clearance and dosage affect event free survival (EFS). Higher serum concentration and area under the plasma concentration curve (AUC) were not associated with an improved EFS. Methotrexate clearance was not found to be of prognostic significance. Patients who tolerated only low 6-mercaptopurine (6-MP) doses because of neutropaenia and those who randomly were prescribed higher doses of Mtx had a lower rate of leukaemia relapse after the completion of therapy. This suggests that the use of maintenance therapy in maximally tolerated doses may be associated with an increased survival in childhood ALL."} +{"text": "Prognostic information is essential for the evaluation, judgement and optimal treatment of patients with squamous cell cancers (SCCs) of the upper aerodigestive tract. Using immunohistochemical and flow cytometric techniques, we have studied the significance of cellular expression of the Ki-67 antigen, epidermal growth factor receptor (EGFR), the transferrin receptor (TFR) and DNA ploidy status in a prospective analysis of patients with SCCs of the head and neck region. All 42 fresh tumour samples expressed both EGFR and TFR to varying degrees. Receptor expression was most marked on the peripheral invading margin of cancer cell islands although staining was also demonstrated in a random fashion within cellular islands and consistently along the basal cell layer of overlying stratified squamous epithelium. The percentage of cancer cells that reacted with the Ki-67 monoclonal antibody was assessed as low (less than 10%) in 15 samples (35.8%), intermediate (10-30%) in 19 samples (45.2%) and high (greater than 30%) in eight samples (19.0%). Eleven of 15 samples (73%) with a low percentage reactivity were DNA diploid, whereas seven of eight samples (87.5%) with a high percentage reactivity were DNA aneuploid. Poorly differentiated SCCs were significantly more often aneuploid than were either moderately or well differentiated tumours. Our results suggest that EGFR and TFR are widely distributed on SCCs, especially on proliferating cells at the invading tumour margin. In addition, there is a close spatial correlation between cells expressing EGFR, TFR and those expressing the Ki-67 antigen. Tumours in which the staining intensity for both EGFR and TFR was intense invariably expressed the Ki-67 antigen in a high proportion of cells. Further patient follow-up will be important in determining whether intense EGFR and TFR staining, combined with a high percentage reactivity with Ki-67 antibody and DNA aneuploidy, will ultimately define a subset of head and neck cancer patients with a poor clinical outcome."} +{"text": "ABCA4), connexin 36 (CX36), c-mer tyrosin kinase receptor (MERTK) and photoreceptor cell retinol dehydrogenase (RDH12) were investigated in order to identify mutations leading to autosomal recessive (ar) gPRA in 29 breeds of dogs.Generalized progressive retinal atrophy (gPRA) is a hereditary ocular disorder with progressive photoreceptor degeneration in dogs.

In the present investigation the differences in the behaviour of leukaemia in immature and mature rat testis and the interactions of testicular and leukaemic cells were studied. Intraperitoneal injection of rat T-leukaemic cells to sexually immature animals induced testicular infiltrations in 100% of animals in 17 days. The infiltrations were small and located perivascularly in the interstitial tissue. Intraperitoneal injection of T-leukaemic cells to sexually mature animals induced testicular infiltrates in 42% of the animals. Leukaemic cells injected directly to the lymph sinusoids of sexually immature and mature testis proliferated rapidly causing testicular enlargement. The M(r) > 5 K fraction of extracts of 50 days old normal rat testes inhibited 3H-TdR incorporation of both normal and leukaemic ConA-stimulated rat lymphoblasts significantly. The same fraction of extracts of testes of 25 days old rats did not have any effect on 3H-TdR incorporation. The normally occurring pubertal increase in the lymphocyte inhibitory effect of the M(r) > 5 K fraction of testis extracts on 3H-TdR incorporation of PBL was prevented following either intraperitoneal or intratesticular injection of rat leukaemic lymphoblasts administered at the age of 25 days. The present observations suggest that physiological pubertal changes in the permeability of vascular endothelium and immunosuppressive effect of the testis may be important explanatory factors for the smaller number of testicular relapses in men compared to boys seen after treatment of ALL."} +{"text": "In the Edinburgh Randomised Breast Screening Project (EBSP) to December 1988 there were 500 cancers in the study population invited to screening and 340 cancers identified in the control population.

The cancers detected by screening were predominantly 'early stage', with 16% noninvasive (PTIS) and 42% invasive stage I (pT1 node negative), whereas cancers were frequently 'late stage' (more than pT2) and inoperable in nonattenders (44%) and controls (36%).

Even the introduction of marrow ablative chemotherapy with autologous rescue has not significantly improved the outlook for these children, presumably because of a failure to eradicate minimal residual disease. One additional approach which may hold promise is the use of immunomodulation with cytokines such as IL2 in the setting of minimal residual disease (MDR), for example after intensive chemotherapy and ABMT. However, considerable variability in the susceptibility of neuroblastoma cells to natural killer (NK) and lymphokine-activated (LAK) killing has been observed, and it is presently unclear how NK and LAK cells recognise neuroblastoma cells. In this paper we examine expression of cell adhesion molecules on neuroblastoma to determine which of these modify interaction with NK and LAK cells. We find that LFA-3 (CD58), the ligand for CD2 is of predominant importance in predicting susceptibility of neuroblastoma to the cytotoxic actions of NK and LAK cells, while expression of ICAM-1 (CD54) may also modify susceptibility. These findings were confirmed by blocking experiments in which co-culture of target cells with ICAM-1 and LFA-3 reduced LAK and NK cytotoxicity. Study of the immunophenotypic features of each patient's neuroblastoma cells before induction of MRD may be valuable in determining the likely effect of IL2 in predicting disease reactivation."} +{"text": "Antipsychotic medications are widely prescribed for the treatment of psychotic disorders but carry a variable propensity to increase weight. Thus metabolic dysfunction is the primary cause of premature death in psychosis patients. A system-based approach to understanding the molecular mechanisms behind metabolic dysfunction can potentially provide scope for tailored interventions and alternative treatment pathways that avert such risks on an individual basis. The aim of this study is to identify transcriptomic predictors of high Body Mass Index (BMI) and blood glucose in first episode and chronic psychosis patients.100 first-episode and 100 chronic cases of psychosis meeting ICD-10 criteria (F20-29 and F30-33) were recruited as part of 2 independent studies from 3 NHS Trusts: South London and Maudsley (SLAM), Oxleas and Sussex. Cases were ethnically mixed and aged between 18\u201365. All participants gave informed consent for biological sampling and a range of physical health assessments. Blood glucose was measure using HbA1c while height and weight data were also taken and used to calculate BMI. For FEP subjects biological measures were taken at baseline, 3 months and 12 months post recruitment. RNA samples were collected at the baseline timepoint via PAXgene blood tubes and interrogates, using the Illumina HumanHT-12.v4 beadchip array. Samples were run at the National Institute for Health Research\u2019s (NIHR) Biomedical Research Centre for Mental Health (BRC-MH) at the Institute of Psychiatry, Psychology and Neuroscience. A total of 4756 probes passed a stringent quality control across the 200 samples.Quantitative data on BMI and hba1c levels were used to assess the predictive efficacy of variables grouped by source in first episode psychosis patients. All the predictor categories were included in the initial model, although individual categories were then dropped one at a time. This leave-one-out strategy allowed the direction, impact and relative contribution of the different feature classes to be assessed. Gene-expression and clinical features were consistently associated with the lowest Mean Squared Error after 100 iterations of K-fold cross-validation and after 11 different values of the alpha parameter across 500 imputed datasets. Hba1c or BMI was used as the clinical predictor, depending on whether Hba1c or BMI was used as the target variable. Unattributed surrogate variables derived from surrogate variable analysis (n=6) were analysed within the technical feature set. Having established that gene expression has inherent value as a predictor of metabolic status the same analytical steps were repeated for the discretised versions of these traits (ie. diabetes and obesity). Top-ranking gene transcripts were compared between the quantitative and discretised models. Rank lists of transcripts were subsetted to allow the power distribution across ordered transcripts to be profiled.The top performing transcripts identified are undergoing validation analysis in the chronic sample. Results will be conveyed in terms of sensitivity and false positive rates (ie. the area under the Receiver Operating Characteristic curve).

The current study explored whether polyphenolics isolated from virgin coconut oil (VCO) prevent Cd-induced dyslipidemia and investigate the underlying mechanism of action, in rats.Rats were pretreated with VCO polyphenols 2 weeks prior to concurrent Cd administration (5 mg/kg) for 5 weeks. Subsequently, serum concentrations of lipid and lipoprotein cholesterol and cardiovascular risk ratios were determined. Hepatic activities of superoxide dismutase (SOD) and catalase (CAT) as well as reduced glutathione (GSH) and malondialdehyde (MDA) contents were analyzed.Sub-chronic Cd administration significantly increased the serum levels of total cholesterol, triglycerides, low density lipoprotein cholesterol and very low density lipoprotein cholesterol while markedly reduced high density lipoprotein cholesterol. Hepatic activities of SOD and CAT as well as GSH content were suppressed by Cd, whereas MDA level was obviously increased. The co-administration of VCO polyphenol with Cd remarkably restored lipid profile and cardiovascular risk ratios and stabilized antioxidant defense systems comparable to control group.This is the first study presenting that polyphenols isolated from VCO prevent Cd-induced lipid abnormalities and cardiovascular risk ratios by improving antioxidant defense systems.

Our results show that the emergence of USUV is a further threat for birds in Europe and that the large-scale impact on population levels, at least for common blackbirds, must be considered.Usutu virus (USUV) is an emerging mosquitoborne flavivirus with an increasing number of reports from several countries in Europe, where USUV infection has caused high avian mortality rates. However, 20 years after the first observed outbreak of USUV in Europe, there is still no reliable assessment of the large-scale impact of USUV outbreaks on bird populations. In this study, we identified the areas suitable for USUV circulation in Germany and analyzed the effects of USUV on breeding bird populations. We calculated the USUV-associated additional decline of common blackbird ( In addition, we selected a new set of 10,000 random background points for each model. We weighted background points and occurrence points equally in each of the 300 BRT models, which we averaged for the final USUV distribution map. We converted the continuous distribution map for USUV to a binary map with areas that are suitable or unsuitable for USUV. Following Pigott et al. (We applied an ensemble boosted regression tree (BRT) approach using R software and 10 subsets for test datasets (comprising 90% of the presence and background observations) each. We used the training datasets to assess the ability of the models to predict the test dataset with the area under the curve (AUC) statistic. We averaged the AUC values of the models across the 10 models of each split sampling dataset and finally across the 300 average AUC values. Furthermore, we applied a pairwise distance sampling procedure to avoid AUC inflation due to spatial sorting bias, which is considered to give a more realistic quantification of the model performance especially regarding its transferability (Cyanistes caeruleus), common chaffinch (Fringilla coelebs), Eurasian magpie (Pica pica), European greenfinch (Chloris chloris), black redstart (Phoenicurus ochruros), great tit (Parus major), common blackbird, house sparrow (Passer domesticus), Eurasian tree sparrow (Passer montanus), common swift (Apus apus), common house martin (Delichon urbicum), carrion crow (Corvus corone), common wood pigeon , European robin (Erithacus rubecula), and common starling (Sturnus vulgaris).

This has led to changes in the frequency of extreme events of flood and drought in recent decades and in the magnitude of the annual flood pulse, a phenomenon that influences virtually all aspects of river-floodplain ecosystem dynamics. Analysis of long-term data revealed abrupt and synchronous changes in hydrology and fish assemblage structure of a floodplain lake near the confluence of Amazon and Negro rivers. After an intense drought in 2005, the assemblage assumed a different and fairly persistent taxonomic composition and functional structure. Declines in abundance after 2005 were more pronounced for species of all sizes having equilibrium life history strategy, large species with periodic life history strategy, and for all trophic levels except primary consumers. Our results suggest that the extreme drought triggered changes in the fish assemblage and subsequent anomalous hydrological conditions have hampered assemblage recovery. These findings stress the need to account for climatic-driven hydrological changes in conservation efforts addressing aquatic biodiversity and fishery resources in the central Amazon. Climate change is impacting biodiversity and ecosystem services on a global scale46789111213Hydrology in the middle reaches of the Amazon is regulated by precipitation in catchments that span a vast portion of the basin6616Consequences of hydrological changes on the Amazonian fish fauna are poorly understood. Only a few studies have examined impacts of recent climatic change on aquatic ecology in the Amazon, and these have analyzed responses to drought over relatively short time intervals18Here we investigate temporal changes in fish assemblage structure during the period of 1999\u20132014, when the central Amazon experienced abnormally large inter-annual hydrological variation. To evaluate trends in inter-annual and intra-annual hydrologic variation, we analyzed river discharge data from 1950 to 2014 using principal components analysis (PCA). Multivariate ordination methods also were used to assess taxonomic and functional assemblage structures, the latter according to two ecological aspects: life-history strategies and trophic positions. Fish abundance data were obtained from standardized fish surveys conducted in a floodplain lake near the confluence of Negro and Amazon rivers .

Such difficulties are strongly predictive of functional outcomes, but there is a lack of effective therapeutic interventions [3].Transcranial direct current stimulation (tDCS) is a novel neuromodulatory technique with emerging evidence of potential pro-cognitive applications; however there has been a dearth of understanding of mechanistic effects of this intervention [4].The aim of this study was to evaluate the neurophysiological effects of tDCS during WM and EF assessment in individuals with schizophrenia.We utilized functional magnetic resonance imaging (fMRI) to evaluate the impact of tDCS on WM and EF in individuals with schizophrenia, randomized to receive either \u2018real\u2019 or \u2018sham\u2019 (placebo tDCS). Participants completed a WM (blocked 0\u20133 back) and an EF (color-word Stroop) during 30 min of 2mA tDCS applied to Broadman area 10/46 (anode 35cm2); with cathode placed on right supraorbita. Sham stimulation was applied for 30 sec. tDCS was applied during fMRI (online) [5].In addition to whole brain, we also conducted task relevant region of interest analysis (ROI) to compare mean frontal and prefrontal (Broadman are 10/46 mask) and anterior cingulate cortex (ACC) activity between the two groups during tDCS. All analyses were restricted a p-value of 0.05, following family wise-error correction (FWE).There were no between-group differences in socio-demographic or clinical characteristics (Tab 1.) Participants did not differ on WM task performance during online tDCS (Tab 2). However, there were significant between-group differences in manipulation of information with the real tDCS performing significantly better than sham, controlled for baseline after consolidation [6].During WM the ROI analysis demonstrated increased activation underneath the site of the anode in the medial frontal gyrus in the real tDCS group, as compared to sham. There was a positive correlation between with consolidated performance and the activity in the medial frontal gyrus.Further, tDCS demonstrated significantly reduced activation in the left cerebellum.During EF task, increased performance was associated with decreased activity in the ACC [5].This is the first tDCS study to examine the brain activity during WM and EF assessment in individuals with schizophrenia using fMRIThis data suggests that biasing the membrane potential of neuronal populations in the frontal cortex seems to improve their response to other inputs i.e. decreased BOLD activation in the WM and EF network. Although the mechanism of action of tDCS is not clear yet [6], one may speculate that if the BOLD response represents synaptic activity [7], including input from other areas, then tDCS might increase the probability that a synaptic input will generate a response in an output neuron, without the need of any additional energy expended by the cell. tDCS offers a potential new therapeutic approach to the treatment of cognitive deficits."} +{"text": "Progranulin deficiency in humans is associated with neurodegeneration.

The aim of this study is to determine the extent to which visual assessment of RV size using 2DE would wrongly classify individuals that should be considered for PVR.CMR and 2DE results were obtained from 61 patients with a history of rTOF. Patients were first classified into events and non-events , based on three cutoffs of RV volume determined by CMR . For each event and non-event group, patients were then reclassified based on presence of greater-than-moderate RV dilation determined qualitatively by 2DE. The net reclassification index (NRI), a measure of prediction improvement, was calculated for each of the three CMR cutoff values. Negative NRI values suggest poorer prediction with 2DE, while positive values suggest improved prediction.

Innate immunity is the first defense mechanism employed against invading bacterial pathogens through the recognition of conserved molecular patterns on bacteria by pattern recognition receptors (PRRs), especially the toll-like receptors (TLRs). TLRs recognize distinct pathogen-associated molecular patterns (PAMPs) that play a critical role in innate immune responses by inducing the expression of several inflammatory genes. Thus, activation of immune cells is regulated by cytokines that use the Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathway and microbial recognition by TLRs. This system is tightly controlled by various endogenous molecules to allow for an appropriately regulated and safe host immune response to infections. Suppressor of cytokine signaling (SOCS) family of proteins is one of the central regulators of microbial pathogen-induced signaling of cytokines, principally through the inhibition of the activation of JAK/STAT signaling cascades. This review provides recent knowledge regarding the role of SOCS proteins during bacterial infections, with an emphasis on the mechanisms involved in their induction and regulation of antibacterial immune responses. Furthermore, the implication of SOCS proteins in diverse processes of bacteria to escape host defenses and in the outcome of bacterial infections are discussed, as well as the possibilities offered by these proteins for future targeted antimicrobial therapies. Cytokines are signaling molecules secreted by cells to elicit a particular effect on the behavior and communication of surrounding cells family of proteins apparently are modulators of a variety of diseases including those with autoimmune etiologies, inflammation, allergies, bacteria, and cancer. SOCS regulate signaling pathways on an intracellular level to potently and specifically inhibit cytokine and growth factor signaling that have evaded detection by complement or antibody and protein tyrosine phosphatases (PTPs) are negative regulators that activate the JAK/STAT pathway effectors of PRRs , led to the blockage of cytokine expression. In addition to IFN-\u03b2 signaling, which is involved in the GAS-induced SOCS1, the TLR4/MyD88 pathway was observed to play a crucial role in stimulating SOCS1 by forming a complex with JAK1/STAT1 and E. faecalis stimulated an increase in SOCS1 and SOCS3 mRNA transcripts in mouse macrophages by triggering NF-\u03baB and MAPK signaling pathways to regulate the production of pro-inflammatory cytokines and arabinogalactan, and an external layer of hydrophobic mycolic acids and NLRs via TLR2/MyD88-activation of macrophages augment SOCS3 expression, and dislocation of the MyD88/TLR2 pathway modulated SOCS3 expression T3SS and its encoded virulence factor SpiC trigger SOCS3 up-regulation via the ERK1/2 pathway for inhibition of the JAK/STAT inflammatory signaling cascades for its continued survival in macrophages. GAS, which causes various systemic diseases induced SOCS1 that participates in the GAS' evasion of host immune responses in murine macrophages by dampening cytokine expression leading to rapid bacterial infection , the spirochetal agent of Lyme disease, stimulates the expression of SOCS1 and SOCS3 in macrophages to possibly control its inflammatory disorders (Khor et al., B. burgdorferi via CD14 signaling induced SOCS1, SOCS3, and CIS as mediated by the p38 MAPK pathway to control the development of chronic inflammatory etiologies (Dennis et al., Results from studies by Uchiya and Nikai (Uchiya and Nikai, M. tuberculosis, M. avium, and M. bovis (Gao et al., M. bovis infection stimulated SOCS1 and SOCS3 in mouse macrophages, which mediated the inhibition of IFN-\u03b3-stimulated phosphorylation of STAT1 and thereby the subsequent inhibition of growth and activation of macrophages required for the control of this intracellular pathogen (Gao et al., M. tuberculosis (Sahay et al., Various mycobacteria manipulate IFN-\u03b3-driven immunity by inducing SOCS1 and SOCS3 to evade the immune response or hamper the disease control. Augmentation of SOCS1 and SOCS3 levels and their subsequent inhibition of IFN-\u03b3-induced STAT1 were found to alleviate the immune response for several mycobacterial species like in vitro and in vivo (Galm et al., SOCS proteins regulate cytokine signal transduction for maintaining immune functions but still contribute to the onset of immunological diseases and inflammation (Yoshimura et al., in vitro by interacting with the IFN-\u03b3 signaling complex and functionally reducing the phosphorylation of STAT1, which further resulted in inhibiting the production of pro-inflammatory cytokines and chemokines (Jo et al., The regulation of the levels of pro- and anti-inflammatory cytokines and chemokines by the immune system is critical in limiting or modulating the host defense against invading pathogens. SOCS proteins as negative regulators of JAK/STAT represent a promising target for anti-inflammatory therapies (Turkson and Jove, Staphylococcus aureus (Hennessy et al., The exploitation of host SOCS proteins and manipulation of their functions by bacterial pathogens make them particularly attractive therapeutic targets. Therapeutic approaches targeting host-directed immunomodulatory components against bacterial infections have already been described (Finlay and Hancock, A better understanding of the control mechanisms involved in SOCS modulation of immune responses and inflammation is key to developing effective targeted therapeutics and vaccines. Each SOCS protein contributes either to the negative regulation of cytokine signaling or the regulation of many biological processes. The expression of SOCS proteins can define host susceptibility to infection by facilitating accelerated bacterial growth or protecting the host from severe inflammation. However, the direct action of the SOCS-mediated inhibition in inflammatory response is yet to be fully elucidated, thus limiting the progress being made scientifically and clinically by microbiologist and immunologists. Additionally, factors such as increased virulence, mutations and antibiotic resistance over time pose recurring challenges in the control of epidemic bacterial diseases worldwide. Admittedly, SOCS-targeted therapy for bacterial-induced inflammation is provocative, but yet one that should be considered exploring. So far, inhibiting the action of JAKs by small composites or drugs show reparative potential (DiGiandomenico et al., SD did the literature search and exploration and wrote the manuscript.

The risk for VDPV emergence in DRC will remain until population immunity is increased and maintained. The immediate goal is to interrupt VDPV transmission in the outbreak areas so that efforts can be turned toward improving polio vaccination and surveillance in other high risk areas in DRC.Democratic Republic of the Congo has had cases of polio caused by vaccine-derived polioviruses (VDPVs) documented since 2004. The emergence of these VDPVs, which cause paralysis similar to wild polioviruses, can occur where population immunity to poliovirus is suboptimal. After an outbreak of 30 circulating VDPV type 2 (cVDPV2) cases during 2011\u20132012, only five VDPV2 cases were reported during 2013\u20132016. In 2017 , 25 cases of VDPV were reported from three provinces, Haut Lomami, Maniema, and Tanganyika. Among the 25 VDPV cases, 22 were classified as cVDPV2, with 20 associated with an emergence that started in Haut Lomami province and spread to Tanganyika province and two associated with a separate emergence in Maniema province. Despite response efforts, transmission of these VDPVs has not yet been interrupted.Risk for VDPV emergence in DRC will remain unless population immunity to poliovirus is increased and maintained.

In acute myeloid leukemia (AML) the first successes have been in targeting mutations in the receptor tyrosine kinase FLT3. Small molecule inhibitors targeting FLT3 have been in clinical use for the past two decades with many patients showing favorable initial responses; however, development of resistance occurs almost universally. Here we describe mechanisms of resistance to FLT3 inhibitors and ongoing studies aimed at overcoming it.Mutations in FLT3 (FMS-like tyrosine kinase 3) are the most common genetic alteration in patients with AML occurring in approximately 30% of adult and 15% of pediatric patients at the time of diagnosis ; howeverPreclinical studies demonstrating robust anti-leukemic effects of FLT3 inhibition lead to development of ATP-competitive tyrosine kinase inhibitors (TKIs) targeting mutated FLT3 for clinical use. First generation agents with activity against FLT3 such as sunitinib, sorafenib, and midostaurin were multi-kinase inhibitors that also targeted related receptors such as PDGFR and KIT. Given the multi-kinase nature of these compounds, their use was limited due to poor potency against FLT3 and increased toxicity due to off-target activity. To address these concerns, the second-generation TKI, quizartinib (AC220) was developed with increased potency against and selectivity for FLT3. Initial responses to treatment with single-agent quizartinib were promising with 44% of relapsed or refractory FLT3-ITD AML patients achieving a composite complete remission in a phase II study ; howeverFurther analysis of patient samples to better understand mechanisms of relapse revealed secondary point mutations in the FLT3 kinase domain in patients who relapsed during quizartinib monotherapy.The most common quizartinib-resistance conferring mutations occur at the D835 and F691 loci and confer cross-resistance to the first-generation inhibitor sorafenib \u201319. MutaDevelopment of secondary point mutations represent the best characterized mechanism of acquired resistance to FLT3 inhibition; however, resistant FLT3-ITD cells lacking secondary point mutations have been frequently identified indicatiActivation of parallel signaling pathways independent of the FLT3 receptor also plays a role in resistance to FLT3 inhibition. For example, upregulation of the receptor tyrosine kinase AXL has been implicated in resistance to TKIs in a number of tumor types \u201331. SimiThe above findings highlight some of the challenges to successful translation of FLT3 inhibition to clinical application. A number of new inhibitors and dual inhibition strategies have been developed to overcome these barriers. Two of the newer generation FLT3 inhibitors that have advanced the furthest in clinical development are crenolanib and gilteritinib. Crenolanib is a type 1 TKI that is highly selective for FLT3 and PDGFR and retains a high level of activity against D835 mutant FLT3 and to a lesser degree against the F691 gatekeeper mutation . In clinThe ongoing struggles to translate the preclinical promise of FLT3 inhibition into successful clinical use underscore the importance of a deep understanding of the biology of target receptors when developing translational strategies. As it is unlikely that FLT3 inhibition alone will be sufficient to induce durable remissions, ongoing research should be aimed at devising rational combination strategies with other targeted agents based upon understanding of the molecular mechanisms at play. Other promising preclinical lines of investigation include combination with MEK inhibitors or targe"} +{"text": "In late August and early September of 2017, Hurricanes Harvey and Irma swept through the Caribbean and made landfall in the continental United States.

At the local level, we found that sociality among female deer in neighboring social groups (n = 36) was mainly explained by their home range overlap, with two exceptions: 1) during fawning in an area of mixed forest and grassland, deer whose home ranges had low forest connectivity were more social than expected; and 2) during the rut in an area of intensive agriculture, deer inhabiting home ranges with high amount and connectedness of agriculture were more social than expected. At the global scale, we found that deer populations (n = 7) in areas with highly connected forest-agriculture edge, a high proportion of agriculture, and a low proportion of forest tended to have higher weighted network closeness, although low sample size precluded statistical significance. This result implies that infectious disease could spread faster in deer populations inhabiting such landscapes. Our work advances the general understanding of animal social networks, demonstrating how landscape features can underlie differences in social behavior both within and among wildlife social networks.Intraspecific social behavior can be influenced by both intrinsic and extrinsic factors. While much research has focused on how characteristics of individuals influence their roles in social networks, we were interested in the role that landscape structure plays in animal sociality at both individual and population levels.

Despite advances in the prophylaxis and acute treatment of CMV, it remains an important pathogen affecting the short- and long-term clinical outcome of solid organ transplant recipient. The emergence of CMV resistance in a patient reduces the clinical efficacy of antiviral therapy, complicates therapeutic and clinical management decisions, and in some cases results in loss of the allograft and/or death of the patient. Common mechanisms of CMV resistance to ganciclovir have been described chiefly with the UL97 mutations. Here we evaluate Incidence of ganciclovir resistance in 144 CMV-positive renal transplant recipients and its association with UL97 gene mutations. Active CMV infection was monitored by viral DNA quantification in whole blood, and CMV resistance was assessed by UL97 gene sequencing. Six mutations in six patients were detected. Three patients (2.6%) of 112 patients with history of ganciclovir (GCV) treatment had clinical resistance with single UL97 mutations at loci known to be related to resistance . three patients who were anti-CMV drug na\u00efve had single UL97 mutations (D605E) without clinical resistance. Our results confirm and extend our earlier findings on the specific mutations in the UL97 phosphotransferase gene in loci that have established role in ganciclovir resistance and also indicate that clinical ganciclovir resistance due to UL97 gene mutations is an issue in subjects with history of with ganciclovir treatment. D605E mutations remains a controversial issue that needs further investigations. Human cytomegalovirus (CMV) is a member of the Betaherpesviridae subfamily that belongs to Herpesviridae family, a significant human pathogen . The preIn immunocompetent individuals, primary infections are mostly subclinical and self-limited. In contrast, infections in immunocompromised persons including organ transplant recipients are accompanied by some important morbidity and mortality . CMV remIt was in the 1980s that Resistance of CMV to antiviral agents was first observed in the laboratory. OccurreAmong The 3 common antiviral drugs, ie, GCV, foscarnet, and cidofovir, ganciclovir targets both UL97 and the UL54 gene where foscarnet and cidofovir target just UL54 gene , 13.

In accordance with Shahid Beheshti University of Medical Sciences law, only patients who consented to the review of their medical records were included.The aim of this study was to investigate prevalence of GCV resistance in CMV-positive renal transplant recipients and its association with UL97 gene mutations. We utilized clinical specimens submitted to one of the private Virology Laboratory in Tehran for CMV quantitative measurement. A total of 144 post kidney transplant patients (from different transplant centers in Tehran), with quantitative PCR > 2000 copies/mL were included in the study for UL97 sequencing. After obtaining whole blood from patients\u2019 plasma viral DNA was extracted using QIAamp DNA Minikit (Qiagen), in accordance with the manufacturer\u2019s instructions. Viral DNA purification efficiency was analyzed by means of a dual-color detection system supplied with the kit and then they were stored at -20 UL97 gene analysisDrug resistance was evaluated for the UL97 region only by a readily available assay using detection methods previously reported , BrieflyPatients and virus isolates3 to 8\u00d7106 copies/mL serum) were studied. One hundred and forty-four CMV isolates , from 144 immunocompromised patients (post kidney transplantation) with viral load >2000 copies/mL . Clinical data and results of genotypic studies are summarized in Definition of drug resistance and UL97 gene mutation Definition of drug resistance: (no improvement (or with relapses) in CMV viremia or clinical disease during prolonged antiviral therapy especially in the presence of risk factors. Generally, prolonged therapy means 6 or more weeks of cumulative antiviral drug exposure, including more than 2 weeks of ongoing full dose therapy at the time of evaluation). Analysis of CMV DNA by sequencing revealed the presence of 6 single UL97 gene mutations in six patients who had received treatment with GCV .Three patients (2.6%) of 112 patients with history of GCV treatment had clinical resistance with single UL97 mutations at loci known to be related to resistance including an Ala-to-Val mutation at codon 594, MET-to-Thr mutation at codon 460 , and His-to-Gln mutation at codon 520. 3 patients had UL97 mutation without clinical resistance. No clinical resistance or UL97 mutation were observed among patients who were anti-CMV drug na\u00efve. The 6 patients with UL97 mutations were followed for 6 month to see the outcomes.Ganciclovir resistance and clinical outcomeDemographic and clinical characteristics and the outcomes of the 3 patients with UL97 confirmed mutations without clinical resistance and 3 patients with UL97 mutations and clinical drug-resistant are presented in In 3 patients with UL97 mutations without clinical resistance no relapses were seen.Our goal in this study was to determine incidence of ganciclovir resistance in CMV-positive renal transplant recipients and its association with UL97 gene mutations in Iranian post kidney transplant patients. In this study, we analyzed viral DNA in the blood of 144 post kidney transplantation patients (32 patients were anti-CMV drug na\u00efve) with CMV (> 2000 copies/mL) in order to determine incidence of GCV resistance and identify mutations in the CMV UL97 gene associated with clinical resistance to GCV. Clinical GCV resistance with UL97 conformed mutations were detected in 3 of 112 patients (2.6%) with history of GCV treatment. No clinical resistance or UL97 mutation were observed among patients who were anti-CMV drug na\u00efve. GCV has been the drug of choice for treatment of systemic CMV disease. However, long-term therapy, ongoing active viral replication due to factors such as the lack of prior CMV immunity (D+/R-), high levels of immunosuppressive therapy, and suboptimal drug concentrations increase the risk of development of GCV resistance. The UL97 gene is by far the most frequent site of mutations conferring GCV resistance, and extensive work by a number of groups established that nucleotide changes associated with GCV resistance are clustered at codons 460, 520, and 590 to 607. These mutations are A594V, M460T, and H520Q , 15. In The outcome of patients with CMV disease because of ganciclovir-resistant CMV is generally poor, manifested by a high rate of allograft loss as illustrated in our study and those of others -30. In oIn conclusion, CMV disease caused by drug resistant virus is not an uncommon consequence of widespread and increasing rate of GCV use and increase in the incidence of drug-resistant CMV could be subsequent issue. The observations in this study may therefore foreshadow the emergence of drug-resistant CMV as an entity that could threaten the outcome of transplantation. The morbidity of clinical disease because of drug-resistant CMV, the complexity of its treatment, and the poor outcome of patients should be taken into consideration in the determination of concise role of different mutations and their association with clinical resistance and afterword development of optimized strategies for prevention of drug-resistant CMV and also development of drugs with less toxicity."} +{"text": "Bencao (materia medica) literature review is the very first step in the standard authentication procedure of Chinese medicinals. As an important part of China\u2019s cultural heritage, these various bencao (materia medica) texts represent centuries of accumulated wisdom in combating disease and preserving health. In this short review, bencao (materia medica) classics of China are broadly divided into three major categories in our routine practice: mainstream bencao (materia medica), thematic bencao (materia medica) and regional bencao (materia medica). The overall significance and current situation of exploration of bencao (materia medica) literature are summarized as well.Books that record the sources and applications of medicinal materials are commonly known as The Chinese term \u201cbencao\u201d, which literally means \u201crooted in herbs\u201d, reflects the fact that most medicinal materials are derived from botanical sources. Bencao (materia medica) texts of past dynasties primarily describe three aspects of Chinese medicinals: medicinal materials, medicinal properties, and medicinal principles. As an important part of China\u2019s cultural heritage, these various bencao (materia medica) texts represent centuries of accumulated wisdom in combating disease and preserving health. The Complete Collection of Traditional Texts on Chinese Materia Medica, a 410-volume and 246,000-page collection complied by the Association of Chinese Culture Research, includes more than 800 bencao (materia medica) classics from 220 BC to 1911 AD. This collection highlights the value of traditional Chinese medicine (TCM) as a rich source for knowledge-based medical rediscovery due to its documentation of clinical experiences over thousands of years, and also illustrates the monumental challenge of selecting the best parts of TCM for modern innovation bencao (mbencao (materia medica) literature is uniquely developed in Chinese medicine, and represents a tremendous historical and cultural resource as well as an important reference point for clinicians, medical historians, and scientists in disciplines such as new drug discovery and Chinese medicinal authentication. Authentication is fundamental for Chinese medicinal standardization, and bencao (materia medica) literature review is the very first step in the standard authentication procedure of Chinese medicinals bencao (mbencao (materia medica) classics of China are broadly divided into three major categories: (a) mainstream bencao (materia medica): the most influential bencao (materia medica) classics from key historical periods, (b) thematic bencao (materia medica): specialized bencao (materia medica) texts dedicated to specific topics, and c) regional bencao (materia medica): bencao (materia medica) texts focused on medicinal materials from specific regions.In practice, bencao (materia medica) literature. They are the most influential classics from key historical periods.The Divine Husbandman\u2019s Classic of Materia Medica (Shen Nong Ben Cao Jing) This is the earliest extant bencao (materia medica) text, compiled in the Eastern Han Dynasty (25\u2013220 AD). This text records 365 medicinals and summarizes medicinal experiences up to the Han Dynasty. Medicinals are classified into three categories based on their medicinal effects and toxicity. Entries for each medicinal substance include nomenclature, properties, compatibilities, and medical applications. Descriptions of production regions and the ecological environment of some medicinal plants are also recorded briefly.Collection of Commentaries on the Classic of the Materia Medica (Ben Cao Jing Ji Zhu) Tao Hongjing, a physician of the North and South Kingdoms period (420\u2013589 AD), compiled this text by preserving and annotating The Divine Husbandman\u2019s Classic of Materia Medica (Shen Nong Ben Cao Jing) and adding another 365 medicinals. It records 730 medicinals and established the framework of bencao (materia medica) compilations adopted by later generations. In this book, medicinal substances are further classified into seven categories based on their natural properties: jades/stones, herbs, trees, insects/beasts, fruits/vegetables, crops, and medicinals with names but without actual applications.Newly Revised Materia Medica (Xin Xiu Ben Cao) In 659 AD, commissioned by the government of the Tang Dynasty (618\u2013907 AD), this text records 850 medicinals and is considered to be the earliest national pharmacopoeia in China.Materia Medica Arranged According to Pattern (Zheng Lei Ben Cao) Compiled by a physician named Tang Shenwei and published in 1108 AD, this is the most praiseworthy bencao (materia medica) of the Song Dynasty (960\u20131279 AD) as it comprehensively summarizes herbal knowledge up to that time. There are three versions of this book currently in circulation. It records 1746 medicinals and is the only bencao (materia medica) text from the Song and previous dynastic periods that survived intact. It features clearly preserved quotations from previous works and stands out as an important reference point for bencao (materia medica) knowledge leading up to the Song Dynasty.Compendium of Materia Medica (Ben Cao Gang Mu) Written by Li Shizhen, a physician of the Ming Dynasty (1368\u20131644 AD), this text was first published in 1596. It records 1892 medicinal substances. This massive and influential compilation represents the highest academic achievement among all the ancient Chinese bencao (materia medica). It not only comprehensively summarized medical knowledge up to the sixteenth century in China, but also contributed greatly to the development of natural sciences in the world.Over the past 2000\u00a0years, five monumental works stand out in the genre of bencao (materia medica) refer to specialized bencao (materia medica) texts dedicated to specific topics, such as medicinal processing, authentication, dietary therapy, and medicinal properties. Examples include Grandfather Lei\u2019s Treatise on Herbal Processing (Lei Gong Pao Zhi Lun) and Origins of the Materia Medica (Ben Cao Yuan Shi). The former is the first monograph on Chinese medicinal processing, written in about 500 AD in the North and South Kingdoms period; it summarizes the literature and experiences of the ancient practice of processing. The latter stands out in the history of bencao (materia medica) as an outstanding monograph on macroscopic identification, written by Li Zhongli in the Ming Dynasty (1368\u20131644 AD). It is characterized by detailed illustrations and descriptions of diagnostic features of raw medicinal materials. Other examples of thematic bencao texts include the Materia Medica of Dietary Therapy (Shi Liao Ben Cao) of the Tang Dynasty and the Materia Medica for Decoctions (Tang Ye Ben Cao) of the Yuan Dynasty (1279\u20131368 AD). The former was dedicated to the theory and practice of dietary therapy, and the latter to the theory of medicinal properties and clinical experience.Thematic bencao (materia medica) texts record knowledge related to medicinal substances derived from specific local regions. Examples include the Materia Medica from Steep Mountainsides (Lu Chan Yan Ben Cao) and the Essentials of Raw Herbs in Lingnan (Sheng Cao Yao Xing Bei Yao). The former was the first regional bencao (materia medica) with color illustrations dedicated to local medicinal plants; compiled in 1220 AD in the Song Dynasty, it focused on the area around modern-day Hangzhou. The latter was compiled in 1711 AD in the Qing Dynasty (1644\u20131911 AD); it records botanical medicinals used in the Lingnan region, a geographic area located in the southern part of China.Regional Bencao (materia medica) tradition provides a rich record of knowledge that has been gradually refined for centuries, opening a window into the cultural tradition of scholarship and textual research that defines TCM. Bencao (materia medica) literature such as the Compendium of Materia Medica (Ben Cao Gang Mu) illustrates important developments in the broader history of natural sciences in China, and this text has been translated into European languages since 1735 AD. In recent decades, exploration of bencao (materia medica) literature has facilitated dramatic medical discoveries, such as the anti-malarial drug artemisinin from sweet wormwood [bencao (materia medica) literature remains underestimated outside of the TCM community. Therefore, in addition to other aspects of TCM, attention is needed to preserve the cultural resources that lie at the heart of bencao (materia medica).However, at present, the overall significance of daodi medicinal materials, medicinal authentication and Chinese medicinal processing are closely connected to bencao (materia medica) literature [bencao (materia medica) research depends upon a multidisciplinary approach that protects the past while embracing the future.Although our research efforts related to terature \u20139, the f"} +{"text": "Oxytocin and vasopressin mediate a range of physiological functions that are important for osmoregulation, reproduction, social behaviour, memory and learning. The origin of this signalling system is thought to date back ~600\u2009million years. Oxytocin/vasopressin-like peptides have been identified in several invertebrate species and they appear to be functionally related across the entire animal kingdom. There is little information available about the biology of this peptide G protein-coupled receptor signalling system in insects. Recently over 200 insect genome/transcriptome datasets were released allowing investigation of the molecular structure and phylogenetic distribution of the insect oxytocin/vasopressin orthologue \u2013 inotocin peptides and their receptors. The signalling system is present in early arthropods and representatives of some early-diverging lineages. However, Trichoptera, Lepidoptera, Siphonaptera, Mecoptera and Diptera, lack the presence of inotocin genes, which suggests the peptide-receptor system was probably lost in their common ancestor ~280\u2009million-years-ago. In addition we detected several losses of the inotocin signalling system in Hemiptera , and the complete absence in spiders (Chelicerata). This unique insight into evolutionarily patterns and sequence diversity of neuroendocrine hormones will provide opportunities to elucidate the physiology of the inotocin signalling system in one of the largest group of animals. Insects constitute the largest and most diverse group of organisms on earth, contributing to at least half of the global species diversity1a-, V1b- and V2-receptors. Oxytocin and vasopressin signalling is involved in a variety of vital functions both in the periphery and the central nervous system. Oxytocin plays crucial roles in reproduction including uterine contraction or milk ejection, and functions as neurotransmitter in complex social behaviour such as bonding, stress or anxiety66910Here we took advantage of this opportunity to investigate the repertoire of oxytocin/vasopressin-like peptides, namely inotocin peptide hormone precursors, and their cognate family of receptors. Although this peptide G protein-coupled receptor (GPCR) signalling system is thought to date back more than 600\u2009million yearsIn the present study we analysed over 260 invertebrate species of insects and other arthropods for the presence of the inotocin peptide GPCR signalling system. By sequence mining of publicly available genome and transcriptome datasets it was possible to identify and annotate peptide precursor and receptor coding sequences. Furthermore we carried out sequence analyses for conserved motifs on the sequences that were found and performed a phylogenetic analysis of the inotocin receptors. This revealed a unique insight into the phylogenetic distribution and aspects of the evolution of the oxytocin/vasopressin-like peptide GPCR signalling system in arthropods.in 12 out of these 23 species that contain partial sequences we found putative inotocin receptor sequences as well; in the 11 remaining species we cannot exclude the possibility that these inotocin precursor sequences may have been derived as artefacts or sequencing errors] that shared similarity to the neurophysin domain of oxytocin/vasopressin-like precursors (Scolopendra subspinipes (centipede), Atelura formicaria (silverfish) and Leptinotarsa decemlineata (beetle) and three different precursor genes/transcripts in Calanus finmarchicus (crustacean) . The twoX4CPXG contain an alanine or serine residue instead of glycine in position 9; in addition we identified three sequences of putative decapeptides that contain a 4-residue tail before the processing site, i.e. CYIINCIDND in Scolopendra subspinipes, CFITNCPVGG within Lepeophtheirus salmonus and CFITNCPVGS within Caligus rogercresseyi. One unusual sequence had neither an amidated glycine nor a typical amidation processing site (Speleonectes cf. tulumensis - CFILDCPLM-IRN) and hence it remains doubtful whether this precursor will actually be processed to a mature inotocin-like peptide.Sequence analysis of all putative inotocin precursors revealed that there is some degree of conservation within parts of the cysteine-rich C-terminal neurophysin domain . HoweverX4CPXG whereof X4CPXG .

Additionally we found 4 different subtypes in crustaceans, e.g. Daphnia magna , appear to be conserved, which allows distinguishing them from CCAP receptors that contain alanine and valine/leucine/phenylalanine, respectively (AXNPV/L/F) in these two positions (To distinguish inotocin receptors from closely related crustacean cardioactive peptide (CCAP) receptors, which share a high degree of sequence similarity and evolved by gene duplication before Protostomia and Deutorostomia have separated, we aimed to identify sequence motifs exclusively present in the inotocin receptors. Firstly we prepared an alignment of 68 CCAP receptors of insects available at NCBI and 68 invertebrate and vertebrate oxytocin/vasopressin-like receptors that have been previously analysedositions . To confositions .in silico mining strongly relies on raw sequence data quality, completeness of genomes and sampling size, some orders (for instance Mantophasmatodea and Strepsiptera) only contained a few sampled species and hence the apparent absence of the inotocin signalling system in these orders should be treated carefully. Furthermore we identified inotocin precursor and receptor sequences in one species (Arachnocampa luminosa) of the order Diptera (flies), which most likely was due to a contamination of the dataset (FITNCPXG (with some exceptions) is distributed among Chelicerata, Myriapoda, Crustaceans and early-diverging lineages of Hexapoda; the putative peptide CLITNCPKG is almost exclusively present in the monophyletic insects group Polyneoptera (inclusive orders of Zoraptera to Isoptera), and the putative peptide CLITNCPRG is prevalent amongst the latest diverged lines of insects (orders Thysanoptera to Coleoptera).Having identified both inotocin peptides and receptors it was of interest to map their presence across all sampled arthropod species. In 105 species we were able to identify both an inotocin-like precursor as well as the cognate receptor, and in another 64 species we could establish evidence for the presence of the inotocin peptide GPCR signalling system by identification of either peptide or receptor. In addition there are 100 species that showed no evidence for the presence of inotocin precursor sequences or receptors . Bearing dataset . The tax dataset .

There are a few exceptions, for instance the Colorado potato beetle (Leptinotarsa decemlineata) which has two copies of inotocin prepropeptides that encode two different inotocin-like peptides (CLITNCPKG and CLITNCPIG) while all other analysed beetle datasets showed evidence only for one copy of the prepropeptide encoding for the putative mature inotocin peptide CLITNCPRG. Interestingly, six of the identified multi-copy receptor species were found within the subphylum Chelicerata and one in Myriapoda, but not a single species within the Hexapoda. We also analysed four different Daphnia magna transcripts of inotocin receptors, which are probably the result of alternative splicing since these sequences are almost identical except for minor deletions/insertions in intracellular loop 3 as well transmembrane domains 3 and 5. The presence of multiple copies in some of the species could be explained by whole genome or large scale duplication events, which have been reported for Limulus polyphemus26Ixodes scapularisCalanus finmarchicusStrigamia maritima3133343534After defining a global map for the phylogenetic distribution of inotocin peptide GPCR signalling system in insects and other arthropods, we aimed to analyse the molecular structure of inotocin peptides and receptors. The vast majority of all sampled species contain one gene encoding for the inotocin receptor and one for the precursor (referred to as prepropeptide). All of the identified prepropeptides have a similar structure containing a signal peptide, a mature inotocin domain, an amidation/processing signal and a neurophysin domain .

Within the remaining two regions with endemic poliomyelitis (African and Eastern Mediterranean), Afghanistan, Nigeria, and Pakistan have never interrupted transmission of wild poliovirus (WPV). The primary means of detecting poliovirus transmission is surveillance for acute flaccid paralysis (AFP) among children aged <15 years, combined with collection and testing of stool specimens for detection of WPV and vaccine-derived polioviruses (VDPVs)Two principal indicators measure the quality of AFP surveillance. The first is the nonpolio AFP (NPAFP) rate ; an NPAFP rate \u22652 is considered sufficiently sensitive to detect WPV or VDPV cases if poliovirus is circulating. The second indicator is the collection of adequate stool specimens from \u226580% of patients with AFP cases were reported in AFR in 2017. The four WPV1 cases that occurred in AFR in 2016 were reported from Borno state in Nigeria . Among tAmong the 21 EMR countries, 15,951 AFP cases were reported in 2016, and 19,035 in 2017. Two EMR countries (Afghanistan and Pakistan) reported WPV1 cases in 2016 (33) and 2017 (22). The number of WPV1 cases reported by Afghanistan remained constant (13 in 2016 and 14 in 2017); the number reported from Pakistan declined from 20 (2016) to eight (2017). In 2016, one cVDPV2 case was reported in EMR, in Pakistan. In contrast, during 2017, 74 cVDPV cases were reported from EMR. All cases were type 2 and occurred in Syria; the most recent case occurred in September 2017 , resultiSewage sample testing supplements AFP surveillance by identifying poliovirus transmission that might occur in the absence of detected AFP cases isolate and identify poliovirus, 2) conduct intratypic differentiation (ITD) to identify WPV or screen for Sabin (vaccine) poliovirus and VDPV genotype was the only WPV1 genotype circulating globally and was detected in Afghanistan and Pakistan. West Africa B1 (WEAF-B1) genotype was last detected in Nigeria in 2016. Sequence analysis associated with the SOAS genotype indicates that WPV1 cases might have been missed by AFP surveillance in 2017; orphan WPV1 isolates (those with less genetic relatedness [\u226498.5% in VP1 gene] to other circulating viruses) were associated with three of 22 WPV1 cases reported from Afghanistan and Pakistan, indicating possible gaps in AFP surveillance. In 2017, cVDPV viruses with extended divergence from the parental Sabin strain were also isolated from stool specimens of AFP cases and from environmental samples in three countries.The number of reported WPV cases declined to the lowest point ever in 2017; however, reported cVDPV cases increased from 2016 to 2017 because of major cVDPV2 outbreaks in the Democratic Republic of the Congo and Syria. Although most national-level surveillance quality indicators improved in 2017, considerable variation exists at subnational levels, particularly in inaccessible areas, and timely detection of circulating polioviruses can be hampered if active surveillance efforts are not rigorous. Repeated detection of WPV and cVDPV from sewage samples in locations where poliovirus cases have not been detected or where sewage detections have preceded detection in persons can provide early evidence of viral circulation within a community . Strong supervision and monitoring of surveillance performance, especially at subnational levels, is important to achieve high-quality surveillance that can detect poliovirus transmission. Environmental surveillance has been an important supplement to AFP surveillance and, when carefully conducted in populations covered by sewage networks, can improve detection of circulating virus, particularly in high-risk areas with suboptimal AFP surveillance , the fewest number ever reported globally. Polio cases caused by circulating vaccine-derived polioviruses increased from four in 2016 to 96 in 2017 because of large outbreaks in Syria and the Democratic Republic of the Congo. Although surveillance performance indicators are improving at the national level, gaps remain, including at subnational levels. As polio cases decline, sensitive and timely surveillance becomes even more important. As long as polioviruses circulate in any country, all countries remain at risk."} +{"text": "Heredity: The gene family that cheats Mendel.

Postoperative pancreatic fistula formation remains the major complication after distal pancreatectomy. At our institution, we have recently developed a novel bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure technique of the pancreatic remnant during distal pancreatectomy. The aim of this study was to analyze the impact of this approach with regard to technical feasibility and overall postoperative outcome. Patients and Methods. 32 patients who underwent a bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure of the pancreatic remnant during distal pancreatectomy between 2012 and 2014 at our institution were analyzed for clinically relevant postoperative pancreatic fistula formation (Grades B and C according to ISGPF definition) and overall postoperative morbidity. Results. Three out of 32 patients (9.4%) developed Grade B pancreatic fistula, which could be treated conservatively. No Grade C pancreatic fistulas were observed. Postpancreatectomy hemorrhage occurred in 1 patient (3.1%). Overall postoperative complications > Clavien II were observed in 5 patients (15.6%). There was no postoperative mortality. Conclusion. The performance of a bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure of the pancreatic remnant was shown to be technically feasible and may lead to a significant decrease of postoperative pancreatic fistula formation after distal pancreatectomy. Distal Pancreatectomy (DP) is performed as the standard procedure in patients with malignant, cystic, or neuroendocrine tumors and/or chronic pancreatitis in the body and tail of the pancreas . ContinuWe retrospectively analyzed 33 consecutive patients who underwent a bovine serum albumin-glutaraldehyde (BioGlue) sealed fish-mouth closure of the pancreatic remnant during distal pancreatectomy for primary malignant or cystic tumors of the pancreas as well as for chronic pancreatitis at the Department of General, Visceral and Transplantation Surgery, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Campus Virchow, between January 1, 2012, and January 1, 2015. All operations were performed by five experienced visceral surgeons who were all educated about the technical steps of this novel procedure as part of the inclusion criteria of this study. This study was performed in accordance with the Declaration of Helsinki and its amendments and approved by the institutional ethic committee.DP was performed as open surgery in each patient. The extent of the pancreatic resection, as well as the need for additional lymphadenectomy and splenectomy, was determined based on the underlying disease and/or cancer stages. The pancreatic resection was performed in all cases using electrocautery in an incision line, which creates a fish-mouth shaped cutting surface of the pancreatic remnant . After aThe levels of amylase and/or lipase in the blood and in the intra-abdominal drains were routinely measured on the 2nd and 5th postoperative day or immediately in the presence of laboratory or clinical signs of infection. Oral food intake was usually begun on the second postoperative day depending on the patient condition and bowel function. The drains were usually removed within 6 postoperative days if the output was clear and if there were no signs or symptoms of infection. We did not perform a standardized Somatostatin analogue prophylaxis for POPF prevention and pancreatic enzyme were only supplemented in the event of clinical signs of exocrine pancreatic insufficiency.We also did not use a standardized protocol for POPF treatment. The drains were left in situ or replaced interventionally and continuous rinsing of the drain was initiated until the drain secretion was clear and the amylase/lipase had declined back to normal values. A cessation of oral food intake and/or eventually octreotide administration during POPF treatment was decided on individual basis in each patient.The patients who had undergone an additional splenectomy received haemophilus, pneumococcal, and meningococcal vaccination according to current guidelines .All patients were observed in our outpatient department for a postoperative period of at least 30 days.Data collection in all patients included relevant information on their medical history, the pathological examination with regard to the underlying disease and resection margin status and the overall postoperative clinical outcome with documentation of any significant procedure related morbidity, the need for reintervention or reoperation, and the length of hospital stay. Postoperative morbidity was classified according to the Clavien-Dindo classification . POPF anBesides a general analysis of the technical feasibility of this novel approach the primary outcome of our study was to investigate the rate of clinically relevant POPF equivalent to POPF Grades B and C. All other complications within 30 days of the operation were also recorded.Statistical analysis was performed using PASW statistics 19 . Continuous variables were reported using mean or median values where appropriate with range, whereas categorical variables were described using frequencies and percent.Between January 1, 2012, and January 1, 2015, 32 consecutive patients underwent a bovine serum albumin-glutaraldehyde sealed fish-mouth closure of the pancreatic remnant during distal pancreatectomy.There were 15 males (47%) and 17 females (53%) with a median age of 62 years (32\u201377). The indication for distal pancreatectomy was pancreatic adenocarcinoma in 11 patients (34%), intraductal papillary mucinous neoplasm (IPMN) of the pancreas in 7 patients (22%), chronic pancreatitis in 3 patients (9%), neuroendocrine tumors (NET) of the pancreas in 2 patients (6%), mucinous cystic neoplasms (MCN) of the pancreas in 3 patients (9%), cyst adenoma in 4 patients (13%), cyst adenocarcinoma in 1 patient (3%), and leiomyosarcoma in 1 patient (3%). Two of the 32 patients (6%) underwent endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic papillotomy (EPT) and endoscopic pancreas stent placement prior to the operation .A splenectomy was performed in 27 of the 32 patients (84%). Seven patients (22%) underwent an additional multivisceral resection with partial or total gastrectomy in 4 patients (13%), colon resection in 5 patients (16%), and/or partial adrenalectomy in 3 patients (9%). The mean operation time was 199 minutes (116\u2013282 minutes). No patient required intraoperative administration of packed red blood cells. The pancreas tissue texture was found to be soft in 13 patients (41%) and hard in 19 patients (59%) according to the intraoperative assessment of the operating surgeon. Major postoperative morbidity > Clavien II occurred in 5 of the 32 patients (16%). Three patients (9%) developed a clinically relevant POPF Grade B. Each of the three patients could be treated conservatively with a however prolonged hospital stay of 40, 71, and 93 days. No Grade C pancreatic fistulas were observed. Postpancreatectomy hemorrhage Grade A occurred in one patient (3%) as an intraluminal bleeding, which did not require therapeutic consequences. Two patients underwent reoperations, due to an insufficiency of a colon anastomosis in one patient and an abdominal fascial dehiscence in another patient. There was no postoperative mortality. The median length of hospital stay was 12 days (7\u201393) .Postoperative pancreatic fistula formation remains the most relevant complication after distal pancreatectomy with a major impact on postoperative quality of life as well as on health care costs. In patients with an underlying malignant disease POPF may in addition lead to a delayed onset of further essential adjuvant treatment which has been identified as an independent risk factor for early peritoneal recurrence and decreased overall survival .Numerous surgical techniques have therefore been described in an attempt to possibly decrease the incidence and impact of POPF. However, even two recent prospective randomized trials failed to identify an ideal technique for the procedure with the pancreatic remnant. The DISPACT trial compared a stapler versus hand-sewn closure of the pancreatic remnant and the incidence of clinically relevant POPF Grades B and C was reported with 20% and 21% in each group . AnalogoThe creation of a fish-mouth shaped cutting margin of the pancreatic remnant may of course be challenging especially in a rather thin gland and may also be associated with an increased bleeding tendency . Also thThe use of bovine serum albumin-glutaraldehyde (BioGlue) as a sealant is of course rather expensive especially in comparison to widely used fibrin glue. However, several studies showed that the use of fibrin for sealing the cutting surface after PD or DP as well as for occlusion of the main pancreatic duct was not associated with a reduction of POPF , 35. In Complications of bovine serum albumin-glutaraldehyde (BioGlue) application reported in cardiovascular and pulmonary surgery include nerve damage, local or embolic vascular obstruction, and foreign body reactions , 37. L\u00e4mIt should of course be noted that any kind of additional physical barrier may lead to a delayed onset or at least clinical presentation of POPF . As partA reduction in the incidence of POPF may of course not just be achieved by restricting on surgical technical factors alone. Several studies have reported an improved postoperative outcome if EPT or pancreatic stent placement were performed prior to DP .

The second analysis focused on disease resistance (R) genes in order to elucidate possible candidates for breeding of pathogen tolerance/resistance. Ortholog analysis showed that 141 out of the 210 putative oil palm R genes had homologs in banana and rice. These genes formed 37 clusters with 634 orthologous genes. Classification of the 141 oil palm R genes showed that the genes belong to the Kinase (7), CNL (95), MLO-like (8), RLK (3) and Others (28) categories. The CNL R genes formed eight clusters. Expression data for selected R genes also identified potential candidates for breeding of disease resistance traits.

The literature demonstrates that:in utero infected infants at 5 days and 2 weeks of age respectively.6 No HIV PCR sensitivity data for 6-week-old HIV-exposed infants, tested at discontinuation of 6 weeks of daily dose NVP, are available.a single perinatal dose of NVP reduced viral load to below the limit of detection in 38% and 17% of 7the probability of a positive HIV PCR at age 6 weeks in perinatally HIV-infected infants is decreased with multi-drug maternal and/or infant PMTCT prophylaxis8in non-breastfed infants, HIV DNA and RNA PCR sensitivity at 1 month of age for perinatally infected infants was 89%9in formula-fed infants who received 6 weeks of postpartum zidovudine (AZT), with or without other antiretrovirals, 32% of intrapartum-infected infants tested HIV DNA PCR negative at 6 weeks of age but tested positive at 3 months of age10prophylaxis reduces HIV DNA concentrations at birth complicating early identification of infected infants for initiation of early treatment12there are case studies illustrating the challenges of \u2018false negative\u2019 and \u2018indeterminate\u2019 HIV PCR results in early infant diagnosis in the context of current PMTCT prophylaxis and calling for revised diagnostic guidelines.in utero and intrapartum HIV infections in the context of current PMTCT interventions. It is too late to diagnose infants who die prior to 6 weeks of age and to achieve early combination antiretroviral therapy (cART) initiation by 7.4 weeks of age as was done on the Children with HIV Early Antiretroviral Therapy (CHER) trial to reduce early morbidity and mortality.13 It is too early to diagnose in utero and intrapartum infections suppressed by daily dose NVP and/or maternal prophylaxis via the placenta and/or breastmilk.The 6-week test, conveniently scheduled at the same time as the 6-week expanded programme for immunisation (EPI) visit, is therefore too late and too early to detect all in utero and intrapartum HIV infections) can never approach 100% because it detects in utero infection only and cannot detect intrapartum infection, namely an infection transmitted at the time of labour and delivery and essentially in the window period at birth. Prior to the implementation of PMTCT and the use of standardised HIV assays, Dunn et al.\u2019s meta-analysis demonstrated that 38% of all perinatal infections were detectable at birth.14 With World Health Organization (WHO) Option A prophylaxis and a single dose of NVP at birth for infants, Lilian et al. demonstrated that 76% of all early HIV infections were detectable at birth.15 This increase was attributed to more sensitive viral detection assays and a proportional increase in in utero to intrapartum infections as a result of PMTCT prophylaxis targeting intrapartum infections during late pregnancy and delivery. As the majority of women deliver in health facilities in South Africa, identifying all HIV-infected women at delivery coupled with birth HIV PCR testing would yield three-quarters of all perinatal HIV infections with close to 90% coverage.The HIV PCR sensitivity at birth for detecting perinatal HIV infections , low birth weight (LBW < 2500 g) or symptomatic HIV-exposed neonates and those born to women who were unbooked or received a late diagnosis of HIV (e.g. at delivery) or received < 4 weeks of antiretroviral PMTCT prophylaxis or had viral loads > 1000 copies per millilitre or were co-infected with tuberculosis during pregnancy. The Western Cape PMTCT guidelines also recommend targeted birth testing that include additional and slightly modified high-risk factors.17 These high-risk factors predict vertical transmission but not necessarily in utero transmission, and therefore the birth HIV PCR test may be negative.The 2014 South African National Consolidated Guidelines recommend targeted birth testing, namely HIV PCR testing of only those HIV-exposed neonates identified as being at high risk of HIV transmission.in utero and intrapartum infections, on every HIV-exposed infant can be offset by following 2010 WHO guidelines to use HIV rapid tests (HRT) from 9 months of age.18 As the majority of HIV-exposed, uninfected infants demonstrate seroreversion by 9 months of age by testing HRT negative, only those with positive HRT would require HIV PCR tests.19 This approach reduces the number of HIV PCR tests required for symptomatic infants or those requiring testing post-cessation of breastfeeding.Universal birth testing of all HIV-exposed infants may be simpler to implement than targeted birth testing. The cost of performing two early HIV PCR tests, to detect To avoid morbidity and mortality, all positive HIV PCR results require urgent action to (1) confirm the HIV-infected status on a second blood sample and (2) initiate cART. Healthcare facilities require good communication with the laboratory to access positive results within 2\u20137 days and systems for patient follow-up to see all HIV PCR-positive patients as soon as possible. As neonates usually return to their primary healthcare clinic and not the maternity unit for follow-up after birth, ensuring that birth HIV PCR test results reach patients will be pivotal to successful implementation of birth testing. Point of care (POC) HIV diagnosis would facilitate same-day identification of HIV-infected neonates.The results of the second, confirmatory viral detection assay should not delay cART initiation but should be obtained as early as possible because, once cART is initiated, it becomes progressively more difficult to detect HIV either by HIV PCR or viral load testing. The availability of two different POC assays for detection of HIV would facilitate same-day identification and confirmation of HIV infection in neonates.1 fewer cases of intrapartum infection may be identified owing to the viral load lowering effect of the daily dose NVP infant prophylaxis. The 2014 National Consolidated Guidelines cater for this in high-risk infants only by recommending a third HIV PCR at 16 weeks of age where prolonged infant prophylaxis (e.g. daily dose NVP for 12 weeks) has been used.1 The probability that the sensitivity of diagnostic virological assays is affected by antiretroviral prophylaxis has prompted American guidelines to recommend an additional HIV PCR test be performed 2\u20134 weeks after combination antiretroviral infant prophylaxis has been discontinued if negative HIV PCR results were obtained during prophylaxis.20 As for all HIV-exposed and uninfected infants, HIV PCR testing is recommended whenever clinical features suggestive of HIV infection are present and 6 weeks after cessation of breastfeeding (if < 18 months old). If, at 6\u00a0weeks after weaning, the child is \u2265 18 months old, a HRT or HIV enzyme-linked immunosorbent assay (ELISA) test should be performed instead of an HIV PCR test.If the birth HIV PCR test is negative, an HIV PCR test at 10 weeks of age is recommended to detect as many cases of intrapartum infection as possible. If the HIV PCR test is repeated at 6 weeks of age, as per national guidelines,In an evolving PMTCT environment, ongoing monitoring is necessary to assess the impact of early diagnosis of HIV infection in neonates and to ensure that an evidence-based, effective diagnostic algorithm is deployed."} +{"text": "Escherichia coli O103 strains shed in the feces of cattle.

However, spinal cord physicians experienced problems when trying to implement an intermittent catheterisation regime in some spinal cord injury patients in the northwest of England. We present illustrative cases to describe practical difficulties encountered by patients while trying to adopt an intermittent catheterisation regime. Barriers to intermittent catheterisation are (1) caregivers or nurses are not available to carry out five or six catheterisations a day; (2) lack of time to perform intermittent catheterisations; (3) unavailability of suitable toilet facilities in public places, including restaurants and offices; (4) redundant prepuce in a male patient, which prevents ready access to urethral meatus; (5) urethral false passage; (6) urethral sphincter spasm requiring the use of flexible-tip catheters and \u03b1-drenoceptor\u2013blocking drugs; (7) reluctance to perform intermittent catheterisation in patients >60 years by some health professionals; and (8) difficulty in accessing the urethral meatus for catheterisation while the patient is sitting up, especially in female patients.

The staffs included in this study were gynecologists and midwifes working in several positions including managers, supervisors, head of departments and staffs. The total number of 350 staffs was invited to take part in the current study and 299 agreed to participate in the survey. Participants were informed about the aim, benefits and importance of the survey as well as their voluntary participation rights. Written informed consent was obtained prior to actual data collection. Data were collected using series of self-administrated questionnaires including socio-demographic characteristics and the Hospital Survey on Patient Safety Culture (HSOPSC). The socio-demographic and individual characteristics include age, gender, education, working hours per week, ward, organizational position, organizational tenure, work experiences in the current ward and type of employment. The Hospital Survey on Patient Safety Culture (HSOPSC) released by the Agency for Healthcare Research and Quality (AHRQ) to help hospitals assess the safety culture within their organization. The HSOPSC contains 42 items with 5 point Likert responses scale ranging from strongly disagree (1) to strongly agree (5). HSOPSC questionnaire contains both positively and negatively worded items. The average percent-positive score for each dimension was calculated and negative items were reverse scored prior to computing percent positive response. This questionnaire is designed to measure 12 dimensions of patient safety culture and these dimensions are: Supervisor/manager expectations and actions promoting safety (4 items), Organizational learning-continuous improvement (3 items), Teamwork within units (4 items), Communication openness (3 items), Feedback and communication about error (3 items), Non-punitive response to error (3 items), Staffing (4 items), Hospital management support for patient safety (3 items), Teamwork across hospital units (4 items), Hospital handoffs and transitions (4 items), Overall perceptions of safety (4 items), Frequency of event reporting (3 items) and Two outcome variables.

This finding implies that health-care workers in Ilam's hospitals accept the patient safety culture in maternity units, but still are far away from excellent culture of patient safety. Maternal wards are among very important units in each hospital, which require special attentions. Therefore, it is necessary to promote culture of patient's safety among professions working in the maternity units of Ilam's hospital. There are several limitations in this study, which need to be addressed. One of the limitations in this study was lack of evidences in maternity units to compare the results. Therefore, future studies are recommended to assess the culture of patient safety in maternal care units using HSOPSC questionnaire. Another limitation in this study is use of self-reported data.International reports on maternal mortality rate has shown constant decreasing pattern during the last 15 years;Programs aimed at decreasing maternal mortality rate has always been a priority in the Iranian health system and some of these programs are promoting mother and child-friendly hospitals that offer maternal care using professional midwifery staffs;Promoting patients' safety and risk management are of great importance in maternity care units due to the fact that every procedure in this field will affect two individuals (both mother and baby).This study assessed culture of patient's safety in hospitals of Ilam University of Medical Sciences for the very first time and revealed areas of strength and weakness among managers and personnel;The most positively perceived dimension of safety culture was attributed to \u201cteamwork within department\u201d among both managers and personnel.

Eastern Kenya was chosen because of its high production potential of diverse common bean cultivars. The rhizobia isolates were characterized phenotypically on the basis of colony morphology, growth and biochemical features. Rhizobia diversity from the different regions of Eastern Kenya was determined based on the amplified ribosomal DNA restriction analysis (ARDRA) of PCR amplified 16S rRNA genes using Msp I, EcoR I, and Hae III restriction enzymes. Notably, native rhizobia isolates were morphologically diverse and grouped into nine different morphotypes. Correspondingly, the analysis of molecular variance based on restriction digestion of 16S rRNA genes showed that the largest proportion of significant (p < 0.05) genetic variation was distributed within the rhizobia population (97.5%) than among rhizobia populations (1.5%) in the four agro-ecological zones.

The sequences of the primers used for PCR amplification of the 16S rRNA gene were: Y1 forward primer (5\u2032-TGGCTCAGAACGAACGCTGGCGGC-3\u2032) that corresponds to positions 20\u201343 and Y3 reverse primer (5\u2032-TACCTTGTTACGACTTCACCCCAGTC-3\u2032) corresponding to positions 1482\u20131507 for 16S rDNA sequence of hia coli . A negatHae III, EcoR I, and Msp I restriction enzymes (Biolabs) (Polymerase chain reaction products of the isolates and reference strains were digested using Biolabs) . A masteH) was also used to determine the rhizobia diversity in different AEZ of Eastern Kenya.The data on rhizobia genetic diversity based on the different band patterns formed after PCR restriction were coded in binary form and analyzed as described by Table 1). Morphotype III was the most abundant (29%) and morphotype II accounted for a partly 2% of the total number of isolates. All isolates were Gram negative rods and did not absorb Congo red dye when incubated in the dark on YEMA-CR medium . Notably, all isolates turned BTB indicator from deep green to yellow when grown on YEMA-BTB indicating that the isolates were acid producers and fast growers . The colony color varied with milky white, cream white, cream yellow and watery colonies being observed which were either opaque or translucent with either firm gummy or smooth mucoid texture . Most of the isolates had a mucoid texture due to the production of excess EPSs. As expected, all isolates had an entire colony margin but the colony elevation varied consistently with convex and raised colonies being observed on YEMA media . The morphological characteristics of the reference strains Rhizobium tropici CIAT 899 and Rhizobium etli USDA 2667 were closely similar to those of morphotype III while Rhizobium leguminosarum strain 446 closely resembled morphotype V (Table 1).From the field trapping experiment using MAC 13 and MAC 64 climbing beans, 41 pure rhizobia isolates were obtained, which were placed in to nine distinct morphotype groups based on their morpho-cultural and biochemical features . Restriction of the 16S rRNA amplicons of the climbing bean rhizobia isolates using enzymes EcoR I , Hae III and Msp I produced multiple band patterns. Restriction enzyme Msp I produced the most diverse polymorphic patterns.The PCR amplification of the 16S rDNA region produced a single band of approximately 1500 bp (Na = 1.92 \u00b1 0.08) and effective alleles (Ne = 1.55 \u00b1 0.10) compared to other populations (Table 2). Rhizobia isolates from ELM had the highest percentage polymorphic loci (92.31% P) while isolates from EUM and TLM recorded the lowest at 61.54% P. The mean Shannon\u2013Wiener diversity (H) estimate showed that the four rhizobia populations from Eastern Kenya were genetically diverse with rhizobia population from ELM having the highest genetic diversity estimate of H = 0.47 (Table 2). The rhizobia population from zone TLM recorded the lowest genetic diversity estimate of H = 0.31. The average expected heterozygosity (He) varied among the four populations and ranged from 0.21 for rhizobia population from TLM to 0.32 for ELM population (Table 2).Based on ARDRA analysis of 16S rRNA amplicons, rhizobia population from ELM had the highest average number of different alleles within populations . The variation among the rhizobia populations from the four AEZ (2.5%) and two Counties (0.5%) were, however, not significant (Table 3).Analysis of molecular variance (AMOVA) for the four rhizobia populations in Eastern Kenya showed a significantly high genetic variation . Isolates from TUM zone were the most distributed and appeared in all the four quadrants, while isolates from ELM zone were the least distributed .The principal coordinate analysis (PCA) of 41 native isolates from the four zones of Eastern Kenya and three rhizobia reference strains showed considerable differentiation . Rhizobia populations from ELM and TUM clustered together with a bootstrap value of 85% while rhizobia populations from EUM and TLM clustered with a bootstrap value of 82%.Based on the pairwise population matrix of Nei unbiased genetic distance and Euclidian similarity index, the neighbor joining dendrogram clustered rhizobia populations from Eastern Kenya into two main groups . Cluster I comprised of majority of the isolates while cluster III had only one isolate ELM5. The reference strain Rhizobium tropici CIAT 899 which was placed in cluster I, clustered together with native rhizobia isolates ELM33 and TLM32, indicating their close genetic relationship. Native isolates TUM26, TLM28, and EUM23 clustered together despite originating from different AEZ of Eastern Kenya. Rhizobium etli USDA 2667 strain was also placed in cluster I and was grouped together with TLM27 and TUM 41 isolates . The native isolate EUM7 clustered closely to Rhizobium leguminosarum strain 446 in cluster II but in a separate sub-branch.Based on the genetic distance after amplified rDNA restriction analyses and Euclidian similarity index, the phylogenetic tree clustered the native rhizobia isolates into three main clusters I, II, and III estimate of rhizobia populations from Eastern Kenya based on genetic distance of ARDRA pattern analysis showed that the isolates were genetically diverse with rhizobia population from ELM zone having the highest genetic diversity estimate compared to TLM zone, which recorded the lowest diversity. This variation in rhizobia diversity could be due to the differences in agroclimatic and soil conditions of the four sites studied in Eastern Kenya. These results reinforce the promiscuous nature of P. vulgaris L. to nodulate with diverse strains of Rhizobium genetic variation distributed within regions (89%) than among regions (11%) in S. meliloti and S. medicae obtained from drought and salt affected regions of Morocco. Moreover, The analyses of molecular variance (AMOVA) based on amplified 16S rDNA restriction profiles showed a highly significant genetic variation of native rhizobia isolates within rhizobia populations and not among the four populations nor across the two regions (Counties) of Eastern Kenya. Based on ARDRA fingerprints, the low level of genetic differentiation of MAC bean rhizobia could suggest that the rhizobia population within the region is weakly structured. This could be due to the absence of physical barriers to limit gene flow . Human aAgrobacterium, Bradyrhizobium, Rhizobium, and Ensifer). Based on the evolutionary relationship of 41 isolates inferred using Neighbor-Joining method, some of the native isolates clustered closely with the three reference rhizobia strains used in this study. The phylogenetic tree showed a diverse genetic variation among the native rhizobia isolates as evident by the different clusters and sub-clusters.The principal coordinate analysis (PCA) also showed low level of genetic differentiation of native rhizobia isolates from Eastern Kenya and thus showing congruent results with the dendrogram. However, the grouping and distribution patterns of the native isolates did not correspond to the AEZ, and this is an indicative of the likelihood of a common evolutionary origin of the isolates. Similarly, Rhizobium tropici CIAT 899 and R. etli USDA 2667 in cluster I. For instance, native isolates TLM 27 and TUM 41 clustered together with R. etli USDA 2667 while isolate TLM 32 clustered with R. tropici CIAT 899. These indicate the close genetic relationship between some of the native rhizobia isolates to R. tropici CIAT 899, R. etli USDA 2667 and R. leguminosarum strain 446 genetic variation distributed within populations (97%) than among populations (2.5%) in four AEZ of Eastern Kenya. Despite the high diversity shown within the rhizobia population, the Pairwise Population Matrix of Nei unbiased genetic distance of rhizobia populations in the study region showed a narrow range, which is an indication of a weakly structured genetic population and a highly conserved genetic structure of rhizobia within the study area. Further molecular studies using either full or partial gene sequences of bacterial genome, which is more sensitive and has a higher resolution power, needs to be carried out to establish the true diversity of native rhizobia isolates up to the species and strain levels.In this study, 41 rhizobia isolates were obtained from the root nodules of mid-altitude climbing (MAC) beans and based on morpho-cultural and biochemical characteristics, the isolates grouped into nine morphotypes indicating the diverse nature of rhizobia nodulating with MAC beans. Cluster analysis based on genetic characteristics obtained after PCR-ARDRA profiling, showed a larger proportion of significant (JK, OO, JM, and EN conceived and designed the research and data collection tools and participated in drafting the manuscript.

Although Sc of neonatal rat testes are exposed to high levels of FSH and T, robust differentiation of spermatogonial cells becomes conspicuous only after 11-days of postnatal age. We have demonstrated earlier that a developmental switch in terms of hormonal responsiveness occurs in rat Sc at around 12 days of postnatal age during the rapid transition of spermatogonia A to B. Therefore, such \u201cfunctional maturation\u201d of Sc, during pubertal development becomes prerequisite for the onset of spermatogenesis. However, a conspicuous difference in robust hormone (both T and FSH) induced gene expression during the different phases of Sc maturation restricts our understanding about molecular events necessary for the spermatogenic onset and maintenance. Here, using microarray technology, we for the first time have compared the differential transcriptional profile of Sc isolated and cultured from immature (5 days old), maturing (12 days old) and mature (60 days old) rat testes. Our data revealed that immature Sc express genes involved in cellular growth, metabolism, chemokines, cell division, MAPK and Wnt pathways, while mature Sc are more specialized expressing genes involved in glucose metabolism, phagocytosis, insulin signaling and cytoskeleton structuring. Taken together, this differential transcriptome data provide an important resource to reveal the molecular network of Sc maturation which is necessary to govern male germ cell differentiation, hence, will improve our current understanding of the etiology of some forms of idiopathic male infertility.

Optical Coherence Tomography opens new horizons in understanding the etiopathology of amblyopia and seems to highlight morphologic anomalies in the retina of the amblyopic eye. Purpose: The objective of this paper is to analyze the macular thickness, optic nerve changes, and choroidal thickness found in patients diagnosed with amblyopia based on trials reported in the literature.Material and methods: This study analyzes 30 clinical trials regarding amblyopia evaluation with Optical Coherence Tomography. The research articles analyzed were published between 2006 - 2016 and were identified on PubMed database.Results: 19 research studies focused on macular and nerve optic changes, 7 on choroidal changes and 6 on retinal changes after occlusion. The results were discussed according to the type of amblyopia, alteration of macular thickness, optic nerve changes, ganglion cell layer changes, and alteration of choroidal thickness. Conclusions: The results are of great variability, and it seems that macula and choroid involvement is more frequently suggested compared with optic nerve involvement.Abbreviations: OCT = Optical Coherence Tomography, RNFL = Retinal Nerve Fiber Layer, GCC = Ganglion Cell Complex, ACD = Anterior Chamber Depth, BCVA = Best Corrected Visual Acuity The results are often contradictory because, as Kim says, when conducting an OCT in patients with anisometropia it is important to correct the magnification of the device according to refraction and axial length of the eye. Also, results differ depending on the device used [3].Another limitation regarding correct interpretation of OCT in children emerges from the inexistence of international established normative values of macular and retinal nerve fiber layer (RNFL) parameters in children ;- Wang (2012) stated that the average thickness of the foveola is thicker than in normal eyes, but other regions have no significant difference [5];- Wu (2013) showed in his study that hyperopic anisometropic amblyopic eyes have a thicker foveola than the contralateral eyes [6];- Araki (2014) concluded that there are significant differences between amblyopic and fellow eyes that are independent of abnormalities in the visual cortex. He showed that the macular outer retinal thickness (1 and 3 mm regions) is significantly thicker in \u201elazy eyes\u201d [7].- Demircan (2015) discovered that in patients age 5-42 years the mean central macular thickness in the amblyopic eyes was thicker patients under 12 years [After studying anisometropic and strabic ambliopic patients:9];- The Sydney Childhood Eye Study (2009) affirmed that in children aged 6 to 12 years, central macular thickness may be increased in \u201elazy eyes\u201d, although it is uncertain if this precedes or follows the development of amblyopia [10]; - Al-Haddad (2011) showed in his study that the mean macular thickness was significantly increased in amblyopic eyes compared with fellow eyes. This difference remained significant in the anisometropic group but not in the strabic group. The mean RNFL thickness was similar in amblyopic and fellow eyes [11];- In 2013 Tugcu claimed that in patients with combined (anisometropic and strabismic) amblyopia and in patients with anisometropic amblyopia the thickness of ganglion cell complex (GCC) was significantly increased in both amblyopic and nonamblyopic eyes compared to healthy patients. The strabismic amblyopia group presented with significant reduction in GCC thickness and increased foveal thickness compared to nonamblyopic eyes. He did not found significant differences in morphological and functional measures among amblyopic groups but he detected significant differences in the retinal morphology of both amblyopic and nonamblyopic eyes compared with healthy control subjects [12];- Rajavi (2014) showed that the average foveal thickness of children with moderate and severe amblyopia was 10 microns thicker compared with the congener eye or the control group. Also, male patients had a mean macular thickness thicker than female patients and there was no correlation between the types of amblyopia and macular morphology changes [13]. - Szigeti (2014) revealed that there are subtle changes that affect the outer nuclear layer of the fovea suggesting the possible involvement of the photoreceptors [Concerning deprivational amblyopia:2]; - Kim (2013) investigated OCT changes in deprivational amblyopia due to congenital cataract and concluded that the mean macular thickness in amblyopic eyes was not different from the contralateral eye or control group, but noticed a thickening of the nasal RNFL compared with the fellow eye or control group [14]. - Long (2016) stated that 3 months after surgery, unilateral pediatric cataract patients show no significant interocular anatomical parameters differences except for anterior chamber depht (ACD) and that the parameters evaluated by OCT were not significantly correlated with the final BCVA [15-18].Also, there are scientists like Kee (2006) Repka (2009), Firat (2013) and Yakar (2015) who claim the inexistence of differences between amblyopic patients and the control group in their studies regarding macula morphology .Wu (2013) affirmed in his study that hyperopic anisometropic amblyopic eyes have thicker peripapillary RNFL than the contralateral eyes .Some scientist such as Kee (2006), Repka (2009), Huynh (2009), Firat (2013), Yalcin (2014), Demircan (2015) and Yakar (2015) claimed that there are no differences in RNFL and optic nerve disc morphology between amblyopic patients and control groups [\u2022 Choroidal thickness20-25]. However, Celik (2016) stated that, in young Turkish adults with hyperopic anisometropic amblyopia, the subfoveal choroidal, ganglion cell complex, macular and RNFL thickness measurements were not statistically significant between hyperopic anisometropic amblyopic eyes and normal fellow eyes [25].Morphological changes of the choroid evidenced with the help of OCT were studied by some researchers who certified that in amblyopic patients the subfoveolar area is significantly higher than in the congener eye or control group [\u2022 Are there morphologic changes after occlusion?26-30]. 6 studies were identified regarding the effect of optical correction and occlusion on the retina, optic nerve and choroid morphology. Oner (2016) analyzed central choroidal thickness before and after 6 months of occlusive treatment and reported no thickness reduction of the central choroid after amblyopia treatment. While Miki (2010), Tugcu (2013), and Yassin (2015) did not found differences between macular thickness and RNFL thickness before and after occlusion therapy, Pang (2011) stated that the central macular thickness was reduced after treatment compared with peripheric macular thickness in which changes were not noticed [31].Also, Liu (2010) stated that some children with various types of amblyopia who failed to achieve normal visual acuity after treatment show macular abnormality on OCT examination [Today, with the help of OCT, a new controversy regarding the presence of morphologic retinal changes in patients diagnosed with amblyopia arises. This opens new horizons in better defining amblyopia and can confirm if ocular structure are affected or not. In the last years, scientists have been trying to determine if morphologic changes in the macula, optic nerve, or choroid of amblyopic patients exist. The results are of great variability and, it seems that macula and choroid involvement is more frequently suggested compared with optic nerve involvement.DisclosureNone."} +{"text": "Transthoracic echocardiography (TTE) and focused cardiac ultrasound (FCU) are now considered essential skills and a requirement of training for physicians working in the intensive care unit (ICU) .

This study aims to serologically identify patients with presumed (n)pAIR through determination of both known and unknown ARAs by autoantibody profiling.An antigen suspension bead array using 188 different antigens representing 97 ocular proteins was performed to detect ARAs in serum samples of patients with presumed (n)pAIR (n = 24), uveitis (n = 151) and cataract (n = 21). Logistic regressions were used to estimate the associations between ocular antigens and diagnosis. Validation of interphotoreceptor matrix proteoglycan 2 (IMPG2) and recoverin antigens was performed by immunohistochemistry and immunoblot, respectively.Samples of patients with presumed (n)pAIR exhibited a broad spectrum of ARAs. We identified retinal antigens that have already been described previously (e.g. recoverin), but also identified novel ARA targets. Most ARAs were not specific for (n)pAIR since their presence was also observed in patients with cataract or uveitis. High titers of autoantibodies directed against photoreceptor-specific nuclear receptor and retinol-binding protein 3 were more common in patients with presumed (n)pAIR compared to uveitis . The presence of all other ARAs did not significantly differ between groups. In patients with presumed (n)pAIR, anti-recoverin autoantibodies were the most prevalent ARAs. Validation of bead array results by immunohistochemistry (anti-IMPG2) and immunoblot (anti-recoverin) showed concordant results in (n)pAIR patients.Patients with (n)pAIR are characterized by the presence of a broad spectrum of ARAs. The diagnosis of (n)pAIR cannot be based on the mere presence of serum ARAs, as these are also commonly present in uveitis as well as in age-related cataract patients. Paraneoplastic and non-paraneoplastic autoimmune retinopathy ((n)pAIR) is a rare blinding retinal disorder of unknown pathogenesis. It is presumed that antiretinal autoantibodies (ARAs) are involved in the pathogenesis of (n)pAIR and damage ocular tissue causing poor visual outcome. Symptoms associated with (n)pAIR are progressive visual loss , visual field loss frequently associated with a ring scotoma or loss of the peripheral field, and decreased amplitudes on electroretinogram (ERG). \u20134Paraneoplastic autoimmune retinopathy (pAIR) includes two subgroups: cancer associated retinopathy (CAR) and melanoma associated retinopathy (MAR).

The study was approved by the local ethical committee from the Erasmus University Medical Center and adhered to the tenets of the Declaration of Helsinki. The ethical committee decided that no informed consent of patients was required for the use of the remainder of the diagnostic material, as the samples were anonymized and the patients were not subjected to additional risk or procedures. Samples which were obtained from the biobank included signed informed consent from all participants.

The diagAn additional group of presumed pAIR (CAR or MAR) patients (N = 7) in whom ERG or visual field tests were not performed , but who fulfilled all other inclusion criteria, was included separately. An additional required criterion for these patients comprised the development of a malignancy before or within 3 months after presentation with ocular problems.We collected various clinical data of the patients with presumed (n)pAIR, including patient demographics (age and gender) and ocular characteristics such as complaints of photopsia, complaints of nyctalopia, subjective or objective problems with colour-vision, unilateral or bilateral visual problems and the presence of a malignancy in the medical history or during follow-up.Controls consisted of two groups: 21 serum samples from cataract patients without retinal damage and 151 samples from patients with uveitis of different causes. Patients with age related cataract were included as controls rather than healthy people, as this disorders does not involve retina nor exhibits retinal damage, and represents a clinical setting in which the tests might be employed. Samples of control patients were collected at the department of Ophthalmology of the Erasmus University Medical Center between February 2009 and April 2015. Patient demographics (age and gender) and known malignancies of these patients were registered.Escherichia coli, with an affinity tag consisting of six histidines and an albumin binding domain from streptococcal protein G (His6ABP) and one bead identity went through the coupling process without addition of antigen . After incubation, the coupled beads were washed and stored in a blocking reagent before combining all bead identities to create a bead array in suspension. Samples were distributed across 96-well microtiter plates, together with triplicate aliquots of a sample pool and a buffer blank in each plate for determination of the intra- and inter-reproducibility. Serum samples were diluted 1:250 in assay buffer before being mixed with the bead array. Incubation was performed at room temperature for 2 hours followed by detection of the IgG reactivity by a fluorophore conjugated anti-human IgG Fab fragment and measured in a FlexMap3D instrument (Luminex Corp.).Autoantibody profiling was performed in all serum samples from patients with presumed (n)pAIR (n = 24), uveitis (n = 151) and cataract (n = 21). Antigens used for the autoantibody profiling were selected based on potential relevance to ocular diseases according to literature and previous positive retinal immunohistochemistry staining, resulting in 188 antigens (human protein fragments) representing 97 unique proteins.

We identified ARAs that have already been described in previous studies, such as anti-recoverin autoantibodies, but also identified new retinal targets. Our findings illustrate that serum ARAs are not only present in patients with (n)pAIR, but also in patients with cataract and uveitis. Though some ARAs appeared to be specific for (n)pAIR, their prevalence and consequently their sensitivity as markers for (n)pAIR were low. This autoantibody screening using 188 antigen provides insight into the autoimmune repertoire of patients with (n)pAIR and a base for further validation with independent methods for protein analysis and independent sample cohorts.A gold standard for the determination of ARAs is currently lacking. DifferenIn addition, information on clinical relevance of the specific ARAs and their pathological titres are lacking. A combination of different ARAs was observed in some cases and therefore their individual effects on retinal tissue could not be distinguished.In our study, we performed statistical analyses using different cut-off levels. By using a high cut-off value, a ratio > 25, false positive results were minimized and retinal targets with a high specificity for (n)pAIR were found. The low cut-off value, a ratio of >2 (indicating ARAs with at least twice the reactivity of the negative control), was used for a more sensitive approach, limiting the exclusion of possibly relevant ARA targets with a lower titre. However, with both cut-off values, no ARAs were found eligible for diagnostic purposes. Some ARAs were specific for (n)pAIR, but had low prevalence while others were more frequently identified but lacked specificity.In concordance with previous findings, positive results of serum anti-recoverin autoantibodies were not only observed in patients with presumed (n)pAIR, but also in patients with uveitis and cataract. Furthermore, no association between the presence of autoantibodies directed against recoverin and the presence of a malignancy was found. A discrepancy between the antigen suspension bead array results for anti-recoverin and the anti-recoverin immunoblot was found in three control patients (one with cataract and two with uveitis). The difference in results could be explained by the different techniques used for determination of ARAs imposing differences in analytical performance. Possibly, the number and/or availability of recoverin antigenic epitopes differed between the antigen suspension bead array and the immunoblot technique. The protein fragments we used in this study to screen for autoantibody reactivity in serum were designed to represent unique parts of each target protein. The binding of the autoantibodies towards their target may be influenced by the protein folding of antigens and may differ in comparison to full-length protein arrays or peptide arrays. Both linear and conformational epitopes, recognized by some ARAs, might be missed for some proteins, preventing recognition by certain autoantibodies.The identification of new ARAs in (n)pAIR is in line with findings from previous studies using Western blot analysis for the determination of ARAs., 48 AlthOur present study focused on the autoantibodies prevalent in serum, which reflects systemic production and is probably not influenced by potential production or accumulation of specific autoantibodies within the eye. Analysis of local, intraocular retinal autoantibodies might show an entirely different pattern and may differ in clinical importance compared to retinal autoantibodies found in the peripheral circulation. The importance of locally produced autoantibodies has already been shown in cerebrospinal fluid for the central nervous system. In addition, it is unknown which autoantibodies penetrate from the circulation, through the blood retina barrier, into the retina and cause a local inflammation. Further research addressing the intraocular presence of specific retinal autoantibodies might elucidate the clinically relevant autoimmune processes directed against the retinal tissue in (n)pAIR.A gold standard for the definitive diagnosis of (n)pAIR is currently lacking. Also in this study, the diagnosis of presumed (n)pAIR was based on clinical symptoms. To compensate for this inaccuracy, we used strict inclusion criteria and selected a uniform cohort of patients with unexplained visual loss, visual field defects and decreased or absent ERG while other diagnostic possibilities leading to this configuration of clinical characteristics were (so far as possible) excluded. The presence of ARAs was found in all our patients with presumed (n)pAIR and therefore all fulfilled the criteria for the diagnosis of (n)pAIR.Although the mere presence of ARAs supports the diagnosis of (n)pAIR, it has been stated that there are no specific ARAs which would be exclusive for (n)pAIR and none of the ARAs were identified to be of higher diagnostic value than other ARAs., 9, 14 OIn conclusion, our study identified a heterogenous reactivity pattern of ARAs in serum of patients with (n)pAIR, although the presence of ARAs was not discriminatory between (n)pAIR, cataract and uveitis and exhibited a low sensitivity. Therefore, the diagnosis of (n)pAIR cannot be based on the mere presence of serum ARAs and such presence thus warrants careful interpretation. The determination of ARAs in intraocular fluid might provide more insight into the pathogenesis of (n)pAIR and might indicate more sensitive and specific diagnostic tools. Therefore, future research on the prevalence of ARAs in ocular fluid represents an important next step.S1 Table(DOCX)Click here for additional data file.S1 FigARAs not prevalent in patients suspected of paraneoplastic and non-paraneoplastic autoimmune retinopathy are not shown.* GNAS;GNAZ;GNA11-15;GNAL;GNAQ;GNAI1-I3;GNAO1;GNAT1-T3.(EPS)Click here for additional data file."} +{"text": "Gadus morhua) and turbot in Denmark.

The risk of resistance is about two-fold higher in patients with elevated gamma glutamyl transferase (GGT) levels. We sought to understand the biological mechanisms underlying IVIG resistance in patients with elevated GGT levels.We explored the association between elevated GGT levels and IVIG-resistance with a cohort of 686 KD patients (Cohort I). Gene expression data from 130 children with acute KD (Cohort II) were analyzed using the R square statistic and false discovery analysis to identify genes that were differentially represented in patients with elevated GGT levels with regard to IVIG responsiveness. Two additional KD cohorts (Cohort III and IV) were used to test the hypothesis that sialylation and GGT may be involved in IVIG resistance through neutrophil apoptosis.ST6GALNAC3, a sialyltransferase, as the most differentially expressed gene, we hypothesized that sialylation and GGT are involved in IVIG resistance through neutrophil apoptosis. We then confirmed that in Cohort III and IV there was significantly less reduction in neutrophil count in IVIG non-responders.Thirty-six genes were identified that significantly explained the variations of both GGT levels and IVIG responsiveness in KD patients. After Bonferroni correction, significant associations with IVIG resistance persisted for 12 out of 36 genes among patients with elevated GGT levels and none among patients with normal GGT levels. With the discovery of Gene expression analyses combining molecular and clinical datasets support the hypotheses that: (1) neutrophil apoptosis induced by IVIG may be a mechanism of action of IVIG in KD; (2) changes in sialylation and GGT level in KD patients may contribute synergistically to IVIG resistance through blocking IVIG-induced neutrophil apoptosis. These findings have implications for understanding the mechanism of action in IVIG resistance, and possibly for development of novel therapeutics. Kawasaki disease (KD) is an acute systemic vasculitis of infants and children, that occurs world-wide , but theIn this study, we explored the association of GGT level and IVIG resistance in KD patients to try to understand the biological mechanism of action underlying these two clinical findings. With our systematic analyses of gene regulation and associated clinical findings and outcomes, we hypothesize: (1) neutrophil apoptosis induced by IVIG plays a pivotal role in IVIG responsiveness; (2) changes in sialylation and GGT levels in acute KD patients may contribute together to IVIG resistance by blocking IVIG-induced neutrophil apoptosis.The normal ranges of GGT and alanine aminotransferase (ALT) are shown in Table A in A cohort with 686 subjects with KD (Cohort I) was used to explore the associations between GGT levels and IVIG resistance.

We demonstrated that KD subjects with elevated GGT levels have a unique gene expression pattern that overlaps with the gene expression pattern associated with IVIG resistance. Our study suggests that reduction of circulating neutrophils is one of the hallmarks of the therapeutic effects of IVIG.ST6GALNAC3 and elevated GGT levels may lead to reduced neutrophil apoptosis, and consequently IVIG resistance Nabs against siglec-9 (Nabs-siglec-9) in IVIG can induce apoptosis in neutrophils and contribute to the efficacy of IVIG in the treatment of KD.

Investigations of the molecular mechanisms underlying these disorders have revealed that different degrees of reduced HSP60 function produce distinct neurological phenotypes. While mutations with deleterious or strong dominant negative effects are not compatible with life, HSPD1 gene variations found in the human population impair HSP60 function and depending on the mechanism and degree of HSP60 dys- and mal-function cause different phenotypes. We here summarize the knowledge on the effects of disturbances of the function of the HSP60/HSP10 chaperonin complex by disease-associated mutations.Heat shock protein 60 (HSP60) forms together with heat shock protein 10 (HSP10) double-barrel chaperonin complexes that are essential for folding to the native state of proteins in the mitochondrial matrix space.

This website provides high quality exome sequencing data from more than 60,000 unrelated adults without severe pediatric disease. Of the 95 HSPD1 missense variations 60 have only been seen in one single allele and only 9 have been observed in more than 10 of the ~120,000 alleles recorded , this variation may be disease-associated with reduced penetrance. The most frequently observed amino acid variation in HSP60, HSP60-p.Gly563Ala, has been found in homozygous form in one sporadic Danish spastic paraplegia patient has been reported (Hansen et al., Effects of expressing the SPG13- and MitCHap60-associated mutant proteins on mitochondrial morphology have been assessed in Cos-7 cells transfected with cDNAs encoding the disease-associated mutant proteins (Miyamoto et al., ShRNA-mediated knock-down of HSP60 in human HEK293 cells decreased the steady state levels of the mitochondrial medium-chain acyl-CoA dehydrogenase (Corydon et al., Knock-out of both HSP60-encoding alleles in mice is not compatible with life.

Clinical geneticists should therefore be aware of this and it will be important to collect the knowledge of these rare cases to be able study genotype/phenotype relationships and to assess the disease-causing nature of variations.Different mutations in HSP60 or its partner protein HSP10 lead to distinct phenotypes of neurological disorders with a clear mitochondrial dysfunction pattern. These diseases are very rare as deleterious effects of mutations in these essential genes are not compatible with normal embryonal development (Christensen et al., Besides being affected by mutations, the activity and function of the HSP60/HSP10 complex can also be regulated by its expression levels. The regulation of the transcription levels of both proteins occurs via different elements in the bidirectional promoter. SP1 elements provide robust house-keeping levels of expression and on top of that heat-shock elements, mitochondrial unfolding protein response elements, and STAT3 elements further modulate expression adapting it to specific situations (Zhao et al., Indeed, dysregulation of HSP60 expression in hypothalamus has been implicated with type 2 diabetes mellitus (Kleinridders et al., Finally, posttranslational modifications of the HSP60/HSP10 complex may regulate the activity of the complex.

The synthesized cDNA and isolated DNA were saved as aliquots and stored at \u221280\u00b0C for further analysis.Previously published PCR protocols were used to detect; a) PPR , b) FMD Serological exposure of the 64 wild ruminants to PPR, BVD and BD, BTV, BHV-1, PI3 and pestivirus antigen is shown in The PCR results for PPRV, FMDV, Pestivirus, BTV, OvHV-2 and BHV-1 are shown in Four mouflon, two wild goats and one Indian gazelle were positive for FMDV by PCR on tonsil samples. The only positive Indian gazelle for FMDV was from Tooran and the positive Mouflon were from Tooran (n = 1), Khojir (n = 2) and Angooran (n = 1). Two FMDV positive wild goats were from Khojir National park and Mujen protected region. All positive PCR tests for PPRV, FMDV, BHV-1 and four of the OvHV-2 samples were confirmed by sequencing. Edited nucleotide sequences were compared to the nucleotide sequence database for similarity using BLASTn search tool and was shown to have significant homology to the available sequences for the listed viruses. \u2013S5 FilesThis is the first survey of viral diseases in wild ruminants in Iran. It will provide valuable information for future research in disease ecology and risks associated with transmission of these viruses between wildlife and livestock.Studies have shown that PPRV is endemic in Iran and the other neighbouring countries with multiple devastating outbreaks occurring in domestic and wild ruminants , 22. MorBorder disease is considered as an endemic disease in domestic sheep and goats in Iran and so MFoot and mouth disease has been reported in Mouflon, wild goats and Indian gazelles in several countries , 35. As Previous work in southeast Iran identified the serological existence of Bluetongue virus in domestic sheep with no reports of clinical signs , 44, 78.In this survey all of the seropositive and PCR positive BT samples were seen in Mouflon from Bamo National Park. The locality of this survey overlaps geographically with the district where a high prevalence of BTV is seen in livestock .There was no serological evidence for PI3 and IBR, the main viral infections of Iranian livestock, and there was just one Indian gazelle positive for BHV 1 using PCR. These viruses mainly cause disease in intensively managed livestock populations, so the lack of seroprevalence was expected in wildlife. In addition, BHV 1 infection is rarely seen in small ruminants and the clinical form is mainly associated with intensive feedlot or dairy production industries .PCR tests showed a high prevalence of OvHV-2 in Mouflon. The virus does not produce clinical signs in small ruminants and there have been no reports of clinical disease in wild and domestic sheep and goats , 81. In In conclusion, while there is clear evidence that transboundary disease viruses particularly FMDV, BTV and PPRV are circulating in wild ruminants.

This enzyme is well expressed in various retinal neurons and has emerged as an important player in regulating survival signaling networks in the neuronal tissues. The non-receptor phosphatase can translocate to lipid rafts in the membrane and has been implicated to regulate several signaling modules including PI3K/Akt, JAK-STAT and Mitogen Activated Protein Kinase (MAPK) pathways in a wide range of biochemical processes in healthy and diseased states. This review focuses on the roles of Shp2 phosphatase in regulating brain-derived neurotrophic factor (BDNF) neurotrophin signaling pathways and discusses its cross-talk with various GF and downstream signaling pathways in the retina. PTPN11 gene is a 593 amino acid non-transmembrane protein tyrosine phosphatase (PTP) encoded by Shp2 plays prominent biological roles in regulating several signal transduction cascades affiliated with its function in the early development of vertebrates, cell proliferation, differentiation, transcription regulation and metabolic control as well as multiple GF signaling networks by the Shp2 phosphatase and its implications in the retina.In the retina, Shp2 is well expressed in the ganglion cell layer (GCL) and inner nuclear layer (INL) and its reactivity has been detected in photoreceptors are secreted proteins that regulate neural growth, survival and function by negatively affecting the induction of various cellular apoptotic pathways. Retinal ganglion cells (RGCs) express various neurotrophic factors and are also supported by neurotrophic factors obtained locally from the Muller cells and retrogradely from the brain through axonal flow , the prominent structural constituent of caveolae Figure . Shp2 waThe role of other significant caveolar proteins such as Cavin family members particularly polymerase I and transcript release factor (PTRF) which participate in caveolae formation through its interaction with Cav-1, have not been extensively investigated and their potential cross-talk with Shp2 remains to be explored and in the RGCs In cerebellar granule neurons, Shp2 suppressing functions are reported to abolish axonal regeneration by paired immunoglobulin-like receptor PIR-B/Shp mediated TrkB inhibition , another member of the neurotrophin family, exerts its survival-promoting effects by stimulating neural development and differentiation through MAPK cascade signaling in human glial cells in response to EGF treatment. Zhang et al. demonstrThe EGF-inhibitory impact of Shp2 was also investigated in a glioma cell line (SNB19). Despite lack of proliferation ability of SNB19 in response to EGF stimulation, it was found that interfering Shp2 mutant could reverse the cell\u2019s ability to proliferate following EGF induction signaling cascade which has major functions in cellular processes such as proliferation, differentiation and apoptosis downstream signaling including Ras, Raf, MEK and MAPK cascade. Insulin receptor substrate 1 (IRS-1), one of the major IR substrate is a multisite docking protein which interacts with SH2 domain-containing proteins such as Shp2. Milarski and Saltiel showed tPTPN11 gene mutation (Tartaglia et al., PTPN11 gene in animal studies resulted in extensive retinal degeneration, cell death and optic neuropathy during various developmental stages highlighting its regulatory function in retinal neuroprotection and progenitor retinal cell fate (Cai et al., Shp2 involvement in regulating retinal survival signaling pathways links dysregulation of this phosphatase to various physiological and pathological conditions. Under glaucomatous stress Shp2 leads to preferential RGC degeneration by inhibiting BDNF/TrkB downstream signaling through dephosphorylation and deactivation of TrkB (Gupta et al., in vivo and in vitro studies implied that the major effect of the phosphatase is mediated through its regulatory effects on various GFs and their downstream effectors which activates multiple signaling pathways. In this review we outlined and analyzed the existing evidence regarding Shp2 involvement in BDNF and other GF-dependant signaling networks with a specific focus on the retinal neuronal cells.Shp2 plays an emerging and important role in the retinal development and its preservation. Preliminary Although significant breakthroughs in the functional characterization of Shp2 have provided more knowledge of the physiological importance of the phosphatase, other areas of future study including manipulating Shp2 expression in retinal and other neuronal cell lineage or development of specific phosphatase inhibitors will further define the mechanisms through which Shp2 positively or negatively mediates various retinal signaling pathways. Another fascinating aspect would be considering Shp2 as a potential molecular target to modulate other neuronal signaling pathways thereby serving as mechanism-based therapy. The involvement of Shp2 in broad range of biochemical actions may make it a challenge to develop any specific therapeutic strategy to isolate a particular neuroprotective role. However, prospective investigations probing Shp2 protein expression, post-translational modifications, sub-cellular localization and interactome changes will unravel the role of this protein in various neurodegenerative disease and retinal disorders.The review was conceptualized, written and edited by each of the authors.

He reported having been sexually abstinent while overseas. After 1 week he experienced onset of fever, rash, arthralgia, and ankle edema. Aware of the symptoms of mosquito-borne illnesses prevalent in his region of travel, he assumed he had a mild case of chikungunya and sought no medical attention.A 53-year-old woman (patient 2) who was the sexual partner of patient 1 experienced onset of sore throat, fever, arthralgia, and rash 17 days after her partner\u2019s return to New Zealand (10 days after he had onset of symptoms). She had had no recent overseas travel, had no blood transfusions, and was unaware of having any mosquito bites. Four days after symptom onset, she visited a general practitioner, whose investigations revealed mild neutropenia, normal liver and renal function, no evidence of streptococcal throat infection, and a demonstrated immunity to measles.The rash subsequently spread, and small joint arthralgia worsened. The patient returned to the general practitioner 9 days after symptom onset. Disclosing her partner\u2019s travel history and symptoms and reporting having unprotected sexual intercourse with him after his return to New Zealand (before and during the time he was symptomatic), she enquired about the possibility of Zika virus infection. After discussing the matter with a clinical microbiologist and securing the consent of the woman and her partner, the general practitioner ordered tests for arboviruses common in the male partner\u2019s region of travel. All laboratory tests for chikungunya and dengue viruses were negative for both patients.

In this review we perform a wide-range assessment of literature relating to recent developments in gene expression profiling (GEP) of the primary tumour, to determine their utility in assessing node status. A set of characteristic genes seems to be involved in the prediction of lymph node metastasis (LNM) in colorectal patients. Hence, GEP is applicable in personalised/individualised/tailored therapies and provides insights into developing novel therapeutic targets. Not only is GEP useful in prediction of LNM, but it also allows classification based on differences such as sample size, target gene expression, and examination method. Colorectal cancer (CRC) is one of the most common causes of cancer-related deaths worldwide . Currenthttps://www.verywell.com, Updated 9 April 2017). In another report, nearly 30% of CRC cases with no record of their lymph node metastasis (LNM) status were found during the five-year follow-up to have died because of tumour recurrence. The authors of the latter study concluded that the presence of the occult lymph node metastases (micrometastases) that were not detected by routine examinations might be the cause [Curative surgery improves the CRC patient\u2019s status at least in early stage, but the healing process is not adequate by itself . For exahe cause .The prevalence of micrometastases in patients with early CRC has recently been widely investigated. Published data indicate that even patients with stage I, who seem to have localised disease, may harbor micrometastases that were missed during the clinicopathological tests . In line(1)(a)chromosomal instability (CIN) ,(b)CpG island methylator phenotype (CIMP) ,(c)microsatellite instability (MSI) .A model that consists of three molecular subtypes including:(2)(a)CMS1 (14%), microsatellite instability (MSI) and immune hyperactivation,(b)CMS2 (37%), epithelial involvement, wingless-type MMTV integration site family member (WNT) and MYC pathway interaction,(c)CMS3 (13%), epithelial and metabolic involvement,(d)CMS4 (23%), invasive and metastatic activation of transforming growth factor\u2013\u03b2 (TGF-\u03b2) .A model of four consensus molecular subtypes (CMSs). The members of this model show the following discriminating features:Like other cancer types, CRC occurs by multiple misregulation of oncoproteins or tumour suppressors that impair the intra- and extra-cellular signal balances. The two most applicable models in this field are as follows:These models facilitate the identification of germline mutations of the genes involved in DNA mismatch repair (MMR) including MutS protein homolog 2 and 6 , MutL protein homolog 1 (MLH1), and PMS1 homolog 2 (PMS2), which all cause MSI in patients with hereditary HNPCC/Lynch syndrome . As in MAs previously mentioned, DNA mutations have a huge impact on prognosis and survival rates. However, the impact of thousands of detected mutations on cancer progression has not yet been elucidated, and we are not sure whether some of these mutations cause the cancer (driver mutations) or emerge because of the cancer (passenger mutations). Currently, gene expression profiling of the primary tumours has received a great deal of attention due to its ability to create a detailed picture of the genetic and epigenetic alteration status of tumours.What is the actual value of the gene expression signatures for the prediction of key events such as recurrence or LNM in CRC patients? This question has been the subject of numerous previous studies . GeneralThe detection of high-risk patients with recurrent CRC is arguably the main challenge. In this regard, applying molecular assessment tools could be helpful in identifying cases of occult micrometastasis and potential suitability of adjuvant therapy ,41. AccoOver the last decade, gene expression profiling by microarray has been a pioneering method in the detection of disease-related molecules. Compared with other standard techniques such as RT-PCR, which is not able to evaluate a large number of targets at once, microarray screening provides fast and reliable data with high accuracy from various samples. With microarray, it is now possible to analyse the whole expression pattern of a human genome within 48\u201372 h, thus gathering precious details about related molecular subtypes .Using cDNA microarray technology, Kwon et al. (2004) examined and compared the expression profiling of 4608 genes in 12 CRC tumours versus in noncancerous tissues . AccordiWang et al. (2004) tried to identify new prognostic markers for cancer relapse by DNA chip technology. Their achievement was a 23-gene panel allowing prediction of recurrence in Dukes\u2019 B patients. The panel also provided insight regarding the underlying biological mechanism of rapid metastases; some of these genes are involved with tumour development and cell proliferation. For example, Tyrosine 3 mono-oxygenase tryptophan 5-monooxygenase activation proteins (YWHAH) and Regulator of chromosome condensation 1 (RCC1) are the most important genes governing the G2 checkpoint of the cell cycle and chromosome condensation initiation, respectively . In the Arango et al. (2005) proved that the downregulation of Ras homolog gene, a small GTPase protein known to regulate the actin cytoskeleton, was correlated with shorter survival. This approach is not only useful in Dukes\u2019 C patients\u2019 recurrence predictions but also can be used in the design of clinical management algorithms .Meeh and colleagues used digital long serial analysis of gene expression to elucidate the differences between node-negative and node-positive colorectal tumours. They reported that the development of node-positive CRC occurs, in part, through elevated levels of epithelial Fibronectin 1 (FN1). They suggested that the progression of the CRC from node-negative to node-positive disease may be facilitated partially by FN1 deregulation and the subsequent enhancement of tumour cell migration .In 2009, Watanabe and colleagues determined that gene expression programming could be a useful tool in predicting recurrence in stage III colorectal cancer, and also identified calcineurin binding protein 1 (CABIN1) among discriminating genes that may play a key role in the development of recurrence . AdditioThe other family involved in cancer metastasis is the Forkhead box proteins (FOX). For example, FOXC2, also known as Forkhead Box C2 (FKHL14), has been found to be significantly elevated in patients with lymph node involvement and correlated with the degree of LNM . UpregulIn 2011, Salazar and colleagues developed a robust gene expression classifier (ColoPrint) that can predict relapses in patients with early-stage CRC. According to their study, this method can identify patients with stage II CRC who will experience a recurrence within five years after surgery . The tecBesides ColoPrint, Lenehan et al. (2012) have developed a molecular prognostic examination able to identify tumour recurrence within three years in CRC cases having curative surgery. From analysing the expression changes of 18 key genes involved in regulation of cell signal transduction, gene expression, invasion, growth, angiogenesis, apoptosis, and antioxidation, they identified five genes that could be used in the prediction of tumour recurrence in CRC patients: BMI-1 polycomb ring finger oncogene (BMI), Vascular endothelial growth factor A (VEGFA), Ribosomal protein S10 (RPS10), Ets variant 6 (ETV6), and H3 histone, family 3B (H3F3B). However, the test was validated in stage I and II patients and the authors concluded that \u226512 lymph node samples would be required for accurate prognostication .The results of another study on 196 genes in CRC patients determined that use of the expression pattern of main genes such as Annexin A3 (ANXA3), C-type lectin domain family 4 member M (CLEC4D), Lamin B (LMNB1), proline rich and Gla domain 4 (PRRG4), TNF alpha induced protein 6 (TNFAIP6), Lamin B1 (TNFAIP6), Vanin 1 (VNN1), and Interleukin 2 receptor subunit beta (IL2RB) that participate in tumour initiation and development could act as novel biomarkers for early detection of CRC . In lineGEP has been investigated for its potential to predict the outcome of patients in other cancers, too. M\u00e9ndez et al. (2011) identified five genes (Receptor accessory protein (1REEP1), Ring finger protein 145 (RNF145), CTONG2002744, Myosin VA (MYO5A), and FBXO32) that were differentially expressed between node-positive and node-negative oral squamous cell carcinomas (OSCC), and suggested that this model is applicable for identification of occult metastasis in patients . SimilarAs already discussed, the GEP platform provides a unique opportunity to examine tens of thousands of different candidate genes at a given time. However, like other laboratory methods, GEP technology is limited. The data obtained from GEP are very simple and only consist of the candidate genes. GEP is not able to detect the interactions or signaling crosstalks. Therefore, other data analyses must be performed to elucidate the underlined network, for example, behind the antitumour drug resistance. Thus, different perceptions may be derived from a single raw data point. The other limitation of the GEP approach is the sample type and the method of preparation. The DNA of different types of cells and tissues of the body undergo multiple modifications and express various genes; hence, the quality of DNA extraction and isolation is directly related to the GEP output. This noise is usually resolved by increasing the sample size, but in particular cases, other alternatives such as RNA sequencing technology ,53 or siOverall, for prediction of tumour recurrence and metastasis, GEP analysis has marked advantages compared to routine clinical exams. Using microarray technology, various genes are identified that allow prediction of LNM in CRC cases. Based on this approach, a new classification of CRC has been introduced that reflects the different biological pathways and distinct prognostic features, allowing preselection of patients who would benefit from adjuvant therapies. However, more investigations are also needed to identify the genes associated with poor prognosis profiles, since these may actually prove interesting potential targets for rational development of new cancer drugs."} +{"text": "Arabidopsis thaliana is the most widely used model organism for research in plant biology. While significant advances in understanding plant growth and development have been made by focusing on the molecular genetics of Arabidopsis, extracting and understanding the functional framework of metabolism is challenging, both from a technical perspective due to losses and modification during extraction of metabolites from the leaves, and from the biological perspective, due to random variation obscuring how well the function is performed. The purpose of this work is to establish the in vivo metabolic profile directly from the Arabidopsis thaliana leaves without metabolite extraction, to reduce the complexity of the results by multivariate analysis, and to unravel the mitigation of cellular complexity by predominant functional periodicity. To achieve this, we use the circadian cycle that strongly influences metabolic and physiological processes and exerts control over the photosynthetic machinery. High resolution-magic angle spinning nuclear magnetic resonance (HR-MAS NMR) was applied to obtain the metabolic profile directly from intact Arabidopsis leaves. Combining one- and two-dimensional 1H HR-MAS NMR allowed the identification of several metabolites including sugars and amino acids in intact leaves. Multivariate analysis on HR-MAS NMR spectra of leaves throughout the circadian cycle revealed modules of primary metabolites with significant and consistent variations of their molecular components at different time points of the circadian cycle. Since robust photosynthetic performance in plants relies on the functional periodicity of the circadian rhythm, our results show that HR-MAS NMR promises to be an important non-invasive method that can be used for metabolomics of the Arabidopsis thaliana mutants with altered physiology and photosynthetic efficiency.

These techniques have enabled precise visualization and objective assessments of anterior segment structures; thus, these devices have become essential tools for better diagnosis and treatment of anterior segment diseases including corneal disorders, cataract, glaucoma, and even disorders of the lacrimal system.

This regulatory activity involves arrays of DNA-binding transcription factors and epigenetic factors that modify chromatin structure. Among the chromatin modifiers, trithorax (trxG) and Polycomb (PcG) group proteins play important roles in orchestrating the stable activation and repression of gene expression, respectively. These proteins have generally antagonistic functions in maintaining cell and tissue homeostasis as well as in mediating widespread transcriptional reprogramming during developmental transitions. Plants utilize multiple trxG factors to regulate gene transcription as they modulate their development in response to both endogenous and environmental cues. Here, I will discuss the roles of trxG factors and their associated proteins in post-embryonic plant development. The development of multicellular organisms is driven by precise patterns of gene transcription that are tightly regulated in a spatial and temporal manner. Establishing and sustaining specific transcription states at gene loci are complex, multi-step processes. They require repertoires of sequence-specific DNA-binding transcription factors as well as epigenetic factors that alter chromatin structure and thereby affect accessibility by the transcriptional machinery. Epigenetic regulators classified as trithorax group (trxG) and Polycomb group (PcG) factors are critical for maintaining the stable transcription patterns at developmental regulatory loci by organizing chromatin in an active or inactive state, respectively . trxG anDrosophila as positive regulators of PcG developmental target genes (Table 1). The chromatin remodeling proteins include members of the SWI/SNF, ISWI, and CHD families that utilize ATP to alter nucleosome assembly and distribution AP2 domain transcription factor (TF) genes, which are essential for root stem cell niche maintenance maintenance. The RAM generates the entire underground root system and has a stereotypical organization. Four rarely dividing cells known as the quiescent center (QC) act as a niche that maintenance .Figure 1A). The SET domain protein SET DOMAIN GROUP 2 (SDG2) is the major H3K4 trimethyltransferase in Arabidopsis and is necessary for genome-wide H3K4me3 deposition and BRAHMA (BRM) also regulate RAM activity in Arabidopsis. PKL acts antagonistically to the PRC2 PcG factor CURLY LEAF (CLF) to maintain RAM stem cell activity -CLAVATA (CLV) signal transduction pathway. The homeobox TF gene WUS is expressed in the core of the meristem and confers stem cell identity on the overlying cells . In contrast, the SAND domain-containing proteins ULTRAPETALA1 (ULT1) and ULT2 restrict shoot and floral stem cell activity by limiting the size of the WUS expression domain , FLOWERING LOCUS D (FD) and SOC1, which promote the transition to flowering and APETALA1 (AP1), which confer floral meristem (FM) identity on the primordia that form on the flanks of the primary SAM to reproductive organs (flowers). The timing of this dynamic meristem cell fate switch is critical for plant reproductive success and occurs in response to endogenous pathways such as the age, GA and autonomous pathways (APs) as well as environmental cues including photoperiod, vernalization and temperature . The MADlowering . FT protmary SAM .FLC, SOC1 and FT are crucial to the timing of the floral transition, and a number of trxG factors are involved in these processes . Because the role of epigenetic factors in FLC regulation during vernalization has been extensively reviewed couple removal of repressive histone marks with deposition of active marks and transcription initiation/elongation to sustain high levels of FLC expression. ATXR7/SDG25 also represses the floral transition by binding to the FLC promoter and augmenting both H3K36me3 and H3K4me3 accumulation , a core component of the Arabidopsis COMPASS-like complex (AtCOMPASS) that also binds the FLC locus and promotes its expression by elevating H3K4me3 levels . SVP forSE (SVP) . SVP expcription . BRM repactivity . Thus thFLC transcription is crucial for the transition from the vegetative to the reproductive state. The JmjC domain-containing H3K27 demethylase REF6/JMJ12 promotes flowering independently of photoperiod by repressing FLC transcription that produces floral meristems (FMs) instead of leaves. A small suite of floral homeotic transcription factor genes then specifies the identity of each floral organ \u2013 sepals, petals, stamens, and carpels \u2013 from the outside to the inside of the flower . The actAPETALA3 (AP3) and AGAMOUS (AG) that specify petal, stamen, and carpel identity in the developing flower , which recruit SYD to the AP3 and AG loci by activating AP3 and AG expression, antagonizing CLF activity at the two loci by reducing H3K27me3 deposition and enhancing H3K4me3 deposition (The plant specific TF LFY and the MADS domain TF SEPALLATA3 (SEP3) play crucial roles in activating the expression of MADS box-containing floral homeotic genes such as g flower . SYD and AG loci . At the AG loci enhance ult1 FM phenotypes, and ALP1 promotes floral organ identity gene expression in the absence of LFY . It is becoming clear from recent research that members of all of these categories of proteins play important roles in regulating landmark post-embryonic developmental processes such as meristem maintenance and floral induction. Moreover some trxG factors, such as BRM and ATX1, mediate multiple developmental processes during plant growth whereas others appear to have more restricted roles. The coupling of a core set of reiteratively used trxG components together with stage-, tissue- or process-specific trxG components may provide a flexible mechanism for tailoring the basic process of transcription activation to discrete gene networks in response to changing endogenous and environmental signals during the life cycle.A variety of trxG factors exist in plants that carry out diverse biochemical activities to promote active gene expression states: chromatin-remodeling ATPases, histone methyltransferases, AtCOMPASS core components, histone demethylases, as well as DNA-binding and accessory proteins (Although significant progress has been made in determining the roles of trxG factors in plant development, many gaps in our understanding remain. It still remains to be determined how many trxG complexes exist in plants, not to mention their full composition and whether that composition is static or changes depending on the developmental stage or tissue. The DNA binding proteins that recruit trxG factors to developmental regulatory loci are only beginning to be identified, while elucidating the chromatin signatures of plant stem cell populations can provide a valuable starting point for determining how tissue- and stage-specific epigenetic states are ultimately achieved during development. Finally, much work remains to decipher how developmental switches between trxG and PcG activities are implemented at individual loci as well as broadly across the genome to coordinate widespread transcriptional reprogramming. Further investigation in these areas will provide a more complete picture of how plants are able to maintain and as necessary adjust their gene expression programs during development in response to a wealth of endogenous and environmental cues.The author confirms being the sole contributor of this work and approved it for publication.The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "Introduction: Considering importance of fatty acids in developing coronary artery disease (CAD) and lack of information about saphenous vein which is commonly used as coronary arterial bypass, in this study we investigated differences in fatty acids composition between saphenous vein and aorta tissues in patients with CAD.Methods: Biopsy samples of aortic tissues and saphenous veins as well as blood samples were obtained form 42 patients with CAD.

We observed positive correlations between serum levels of LDL-C with elaidic acid and linoleic acid levels in saphenous. Evaluation of aorta tissue fatty acids revealed that palmitoleic acid (16:1) had positive and arachidonic and linoleic acids had negative correlations with serum HDL-C levels.Conclusion: Our results revealed difference between fatty acids composition of aorta and saphenous vein tissues and existence of correlations between the fatty acids levels with serum lipid profile. The saphenous vein had higher poly-unsaturated fatty acids in compared to aorta tissue and thus this vein is not at risk of atherosclerosis and can be used as coronary arterial bypass. Although many studies have evaluated effects of dietary fatty acids as well as plasma levels of them on coronary atherosclerosis,12 but there is no enough information about fatty acids content and their possible roles in the tissues which are involved in the atherosclerosis.Many studies have been conducted to investigate lipid accumulation in the arterial wall of patients with atherosclerosis but many questions about mechanisms of dyslipidemia and progression of atherosclerotic lesions have been remained unanswered.14 However existence of higher free cholesterols than cholesterol esters in the plaques15 which is in contrary with the finding about high ratio of cholesterol esters/free cholesterol in plasma,16 led to arise theory of coming the lipids from vessels growing into the plaque.17 On the other hand higher levels of fatty acid synthesis in atherosclerotic arteries in compared with intact arteries highlights possible role of fatty acid metabolism in tissues which are involved in atherosclerosis.18It has been reported that cholesterol as one of the major lipids in atherosclerotic plaques which possesses fatty acids, enters from the blood rather than in situ synthesis.19 Also Bahrami et al20 have demonstrated lower levels of unsaturated fatty acids and higher amounts of saturated fatty acids in atherosclerotic aorta in compared with the internal mammary arteries. Furthermore different fatty acids composition of aorta artery and adipose tissue between patients with and without CAD has been shown previously.21 These finding emphasize on importance of local fatty acids composition in developing atherosclerosis and CAD. However there is no information about fatty acids composition of saphenous vein which is commonly used as coronary arterial bypass and also has structural differences with arteries.22 The aim of this study was to investigate differences in fatty acids composition between saphenous vein and aorta tissues, as well as associations between the fatty acids levels with serum lipid profile in patients undergoing CABG.In a study it has been reported that the fatty acids composition of coronary arteries was significantly different between sudden cardiac death and traffic accident victims.2 and the patients with class II and III obesity (BMI \u226539 kg/m2) were not involved. The exclusion criteria were: having acute inflammation, auto-immune diseases, kidney and liver diseases, diabetes, anemia or malignant tumors. Also patients with prior CABG as well as aortic or mitral valve replacement were excluded from the study.Frothy-two individuals (mean age: 53.2\u00b17.5 years), documented as CAD patients were included in this study. All patients had at least two vessels coronary artery disease (\u226550% stenosis) based on the angiographic data and were scheduled for CABG at Shahid-Madani heart hospital in Tabriz, a northwest city of Iran. Also we recruited patients with body mass index (BMI) \u226434.9 kg/mBiopsy samples (1-2 g) were obtained during the surgery from aortic tissues and saphenous veins and then were dissolved in hexane and kept frozen at - 70\u00b0C in glass vials for fatty acid measurement. Also in order to lipid profile analysis, approximately 5 mL of venous blood samples in the fasting state at 8:00 am were taken from all participants and the serums were separated using centrifugation.23 and the percentage of each fatty acid was determined using gas chromatography. In brief, the solution of fat extract in hexane was evaporated under a stream of nitrogen to near dryness, and the lipids were esterified with methanol during catalysis with acetyl chloride. Then fatty acid methyl ester derivatives were separated on a 60- x 0.25-mm Teknokroma TR-CN100 column using gas chromatograph system equipped with a split injector and a flame ionization detector. The oven temperature program was 170-210\u00b0C, 1\u00b0C/min, and then isothermal for 45 minutes. The combined inter- and intra assay of variation was 2.1% for palmitic acid (16:0), 2.7 for linoleic acid (18:2n-6), 18.6 for eicosapentaenoic acid (EPA), and 11.2 for docosahexaennoic acid (DHA). The known fatty acids from Sigma chemicals was employed as standards to peak retention times identification. The levels of fatty acids were calculated as the percentage of each fatty acid of the total.Fatty acids were extracted using the Bligh and Dyer methodThe levels of triglycerides (TG), total cholesterol (TC) and high density lipoprotein-cholesterol (HDL-C) determined by enzymatic colorimetric method with an automated chemical analyzer . Low-density lipoprotein-cholesterol was calculated using the Friedewald formula.t test was used to compare fatty acids levels between saphenous vein and aorta tissues in each patient. Also the Pearson correlation test was applied to investigate possible associations between the fatty acids levels with serum lipid parameters. P values <0.05 were considered significant. SPSS V.16 software was used for the statistical analysis.The data are reported as mean \u00b1 standard deviation (SD). Normal distribution of the data was confirmed by Kolmogorov-Smirnov test. The paired Demographic and clinical characteristics of the studied population are shown in In studied patients mean levels of total cholesterol was higher than normal range (214 \u00b1 45 mg/dL) and mean levels of triacylglycerol, 178 \u00b1 50 mg/dL, was borderline high . Also thP < 0.001). Levels of most unsaturated fatty acids were statistically higher in saphenous tissue than aorta tissue (P < 0.05). On the other hand, mean levels of linoleic acid (18:2 n\u20106) was higher in aorta tissue in comparison with saphenous tissue . Comparing the mono-unsaturated fatty acids levels between saphenous and aorta demonstrated that levels of palmitoleic acid and oleic acid as well as its trans isomer (elaidic acid) were significantly lower in aorta than saphenous vein. The poly-unsaturated fatty acids levels were also different between the two vessels as we observed significantly lower proportions of the trans isomer of linoleic acid (18:2 t), linolenic acid (18:3 n-9) and docosatrienoate acid (22:3 n-3) in aorta in compared to the saphenous. Based on our knowledge, there is no report on differences of fatty acids composition between saphenous and aortic tissues of CAD patients. However, in accordance with our results, in previous studies higher levels of palmitic acid and also lower levels of poly-unsaturated fatty acids in phospholipids of aorta and coronary arteries of patients with CAD in compared with control individuals have been reported.21 Moreover in a study on fatty acids composition of aorta and internal mammary of patients with CAD same as our results, lower levels of unsaturated fatty acids and higher percentage of palmitic acid in aorta samples than internal mammary have been reported.20 Moreover they also found statistically different levels of stearic acid (18:0), arachidonic acid (20:4n-6) and eicosapentaenoic acid (20:5-n3) between aorta and internal mammary arteries.20 We did not find such differences between aorta and saphenous vein maybe due to structural differences between saphenous vein and internal mammary artery.The assessment of fatty acids contents in saphenous vein and aorta of CAD patients indicated that the fatty acids composition between these vessels was different. We found higher concentration of palmitic acid as saturated fatty acid in aorta in compared with saphenous vein were found in aorta tissue as compared to the saphenous vein. Higher levels of linoleic acid in aorta and coronary arteries of individuals with CAD compare to non-CAD subjects and also in aorta in compared with internal mammary artery in patients with CAD have been shown previously.20 However there is no enough information about pattern of fatty acids modification and its role in atherosclerosis pathogenesis.Such differences between fatty acids composition of aorta artery and saphenous vein could be partly due to structural differences between arteries and veins but some part of these differences could also be because of atherosclerosis and cardiovascular complications that the aorta was involved. Reports about different fatty acids composition between aorta and internal mammary of patient with CAD confirm this possibility.33 and thromboxane A2 production.34 In our previous study we also found negative correlations between levels of linoleic acid in epicardial and subcutaneous adipose tissues with serum levels of HDL-C and a positive correlation between this fatty acid content in subcutaneous adipose tissue with serum LDL-C in patients with CAD.35 There are wide evidences that the HDL-C and LDL-C are protective and risk factors for atherosclerosis and its complications, respectively37 and on the other hand linoleic and arachidonic acids have been documented as atherogenic fatty acids which cause inflammation and platelet aggregation.32 So finding the associations between these fatty acids with LDL-C and HDL-C seems reasonable. Moreover, we observed a positive correlation between the HDL value and palmitoleic acid in aorta which confirms the protective effect of palmitoleic acid as MUFAs against CAD.39In this study we detected inverse correlations between serum HDL-C with linoleic acid levels in saphenous and aorta tissues and also with arachidonic acid levels of aortic tissue. Besides, linoleic acid levels in saphenous vein were positively correlated with LDL-C in serum. The negative correlation between HDL-C and arachidonic acid could be explained by results of previous study reported that in CAD patients, HDL-hypocholesterolemia decreases ability of platelet to produce nitric oxide (NO) and consequently reduction in NO levels itself inhibits arachidonic acid metabolism. NO induces the inhibitory influence through various direct and indirect ways such as inhibition of cyclooxygenase activities40 Moreover results of a 25-year follow up study conducted in seven countries, have been showed positive correlation between dietary intake of elaidic acid and serum cholesterol.41 These reports confirm our finding about existence of positive correlation between elaidic acid in saphenous and serum total cholesterol.It has been demonstrated that elaidic acid (18:1t) is cholesterol elevating factor.43 exerts its effects partly via changing serum lipid profile and consequently vessel wall fatty acids composition. Although observed differences in fatty acids composition between aorta and saphenous vein tissues and also between aorta tissues of CAD and NON-CAD patients21 as well as aorta and internal mammary arteries of CAD patients20 emphasize that in addition to diet, local lipid metabolism and existence of atherosclerosis can be determinative factors for fatty acid composition of vessel walls. However the ways that different dietary intake or lipid metabolism could influence tissue fatty acids composition still remain to be elucidated. However, in our study we did not have information about dietary habits and life-style which could possibly affect the fatty acids composition of the tissues. Although it should be noted that in the present study the comparisons were done between two tissues of each patient, so any confounding factor such as dietary habits which could affect the evaluated parameters, affects the parameters of both saphenous and aorta tissues in same patient and consequently could not affect the overall result of our study. Another limitation of our study was lack of proper control without CVD because of impossibility of taking such samples from healthy individuals. However further studies could be conducted on immediately dead persons without CVD or animal models.Considering the association between fatty acids composition of aorta and saphenous tissues with serum lipid profile that was found in the present study, it can be concluded that composition of dietary fatty acids which has been suggested as important factor for CAD developmentIn this study due to the unavailability of healthy individuals saphenous and aorta tissues we could not compare the results with control. Also due to difficulty in finding patients our study was conducted with almost small sample size. Another limitation of our study was lack of information about diet of patients as it can has effect on fatty acids composition of saphenous and aorta tissues.In conclusion our results revealed difference between fatty acids composition of aorta and saphenous vein tissues in CAD patients and existence of correlations between the fatty acids levels and serum lipid profile. Owing our results about higher levels of PUFAs in saphenous vein compared to aorta tissue, it is likely that the vein has almost low risk for atherosclerosis and may be able to be used as coronary arterial bypass.All authors declare no competing financial interests exist.Approval for this study was granted by the ethical committee of Tabriz University of Medical Sciences and the informed written consent was obtained from all participants The work was supported by a grant from the Cardiovascular Research Center, Tabriz University of Medical Sciences.

If alien plants interact with native disperser animals, this can interfere with animal-mediated dispersal of native diaspores. Interference by alien species is known for frugivorous animals dispersing fruits of terrestrial plants by ingestion, transport and egestion (endozoochory). However, less attention has been paid to possible interference of alien plants with dispersal of diaspores via external attachment , interference in aquatic ecosystems, or positive effects of alien plants on dispersal of native plants. This literature study addresses the following hypotheses: (1) alien plants may interfere with both internal and external animal-mediated dispersal of native diaspores; (2) interference also occurs in aquatic ecosystems; (3) interference of alien plants can have both negative and positive effects on native plants. The studied literature revealed that alien species can comprise large proportions of both internally and externally transported diaspores. Because animals have limited space for ingested and adhering diaspores, alien species affect both internal and external transport of native diaspores. Alien plant species also form large proportions of all dispersed diaspores in aquatic systems and interfere with dispersal of native aquatic plants. Alien interference can be either negative or positive . I propose many future research directions, because understanding whether alien plant species disrupt or facilitate animal-mediated dispersal of native plants is crucial for targeted conservation of invaded (aquatic) plant communities. Dispersal of plant diaspores by animals (zoochory) is a globally important mechanism regulating species diversity of plant communities. Key disperser species include birds, mammals, and fish\u2013of which many forage on plant diaspores, transport them internally during digestion, and defecate viable diaspores in new locations alien plant species may interfere with both internal and external animal-mediated dispersal of native diaspores; (2) interference by alien plants also commonly occurs in aquatic ecosystems; and (3) interference by alien plants can have both negative and positive effects on native plants. I focus on zoochory of plant diaspores by vertebrate animals. \u201cAlien species\u201d is used as the terminology throughout this study to refer to all non-native, invasive, introduced or exotic species that established a self-sustaining reproductive population outside their native geographic area feed selectively on Eurasian grasses in Canada and mule deers (Odocoileus hemionus) remove fruits of an alien succulent faster than those of a native species in the same genus studying interference of alien plants with ectozoochory by itself, and simultaneously with interference of endozoochory in single model systems; and (2) comparing the relative effectiveness of alien and native diaspores for endo- and ectozoochory in choice and attachment experiments AND TS = (seed OR diaspore* OR fruit OR nut); combined with either TS = (frugivor* OR endozoochor*) or with TS = (ectozoochor* OR epizoochor* OR exozoochor*). This resulted in respectively 376 and 36 studies that addressed dispersal of alien plants for endo- and ectozoochory. Addition of the term TS = (aquatic OR wetland OR freshwater OR riparian) reduced the publication counts to respectively 16 and 6, indicating that a low percentage of all studies involved aquatic habitats.To compare study effort on alien interference between habitats and among disperser animals, I performed a standardized search for publications reporting the presence of alien and native aquatic diaspores in single samples of feces or attached to native vertebrate animals in ISI Web of Science. On the 11th of January 2018 I entered the following search string: TS = and 55% for ectozoochory . In 5 of the 19 reports on endozoochory and 8 of the 15 reports of ectozoochory more alien than native diaspores were dispersed. However, these numbers should be interpreted with caution because variation among geographic locations and studied species was large, and studies reporting only dispersal of native diaspores were not included.All aquatic studies jointly reported 34 cases of potential interference by alien plants with dispersal of native diaspores\u2014by native disperser animals\u2014and in aquatic ecosystems Tables , 2. The The presented cases illustrate that patterns of alien interference thus far primarily described in terrestrial ecosystems may also apply to aquatic ecosystems. Future research should focus on under-examined disperser animals like fish, bats and reptiles although the phenomenon has been primarily studied for endozoochory by frugivorous birds and mammals in terrestrial ecosystems, alien species may also interfere with ectozoochory and this warrants further studying; (2) interference of alien species with zoochory can similarly be found in aquatic ecosystems; (3) alien plant species can also provide resources such as food or nesting habitat to animals, which can increase densities of native disperser animals or attract new disperser animal species. Through these mechanisms alien plants can also positively affect dispersal of native plants, which warrants further studying. This study illustrates that the impacts of alien plant species on native plant species, whether positive or negative, can vary among native plant species relying on different dispersal mechanisms. Understanding species interactions is crucial for effective conservation, especially in invaded ecosystems.CvL designed the study, collected and analyzed the data, and wrote the manuscript.The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "To respond to the World Health Assembly call for dissemination of lessons learnt from countries that have begun implementing the International Health Regulations, 2005 revision; IHR (2005).In November 2015, we conducted a systematic search of the following online databases and sources: PubMed\u00ae, Embase\u00ae, Global Health, Scopus, World Health Organization (WHO) Global Index Medicus, WHO Bulletin on IHR Implementation and the International Society for Disease Surveillance. We included identified studies and reports summarizing national experience in implementing any of the IHR (2005) core capacities or their components. We excluded studies that were theoretical or referred to IHR (1969). Qualitative systematic review methodology, including meta-ethnography, was used for qualitative synthesis.We analysed 51 articles from 77 countries representing all WHO Regions. The meta-syntheses identified a total of 44 lessons learnt across the eight core capacities of IHR (2005). Major themes included the need to mobilize and sustain political commitment; to adapt global requirements based on local sociocultural, epidemiological, health system and economic contexts; and to conduct baseline and follow-up assessments to monitor the status of IHR (2005) implementation.Although experiences of IHR (2005) implementation covered a wide global range, more documentation from Africa and Eastern Europe is needed. We did not find specific areas of weakness in monitoring IHR (2005); sustained monitoring of all core capacities is required to ensure effective systems. These lessons learnt could be adapted by countries in the process of meeting IHR (2005) requirements. First introduced in 1969, IHR is global legislation requiring countries to link and coordinate specific actions.,,IHR (2005) also requires all countries to develop, strengthen and maintain eight core public health capacities.Although IHR (2005) describes what must be achieved by countries, there is limited knowledge on how countries should proceed in achieving the core capacities.

Some maWe found substantial documentation of lessons learnt from implementing IHR (2005) core capacities globally. Although many factors affected implementation in a country, the structure of the health system, sociocultural factors, economic status and type of governance, we were able to extract some common themes. We found few gaps in implementation in direct relation to the IHR (2005) core capacities. Nonetheless, additional research could be useful in evaluating countries\u2019 core capacity performance against actual disease epidemics. Specifically, we did not identify any documentation evaluating IHR (2005) core capacity development with national performance in preventing, detecting and responding to disease epidemics. This type of evaluation could provide useful data for future revisions of the IHR. Moreover, defining fundamental data needs for new treatments and vaccines could help develop national research capacity to shorten the development window during future disease epidemics. Finally, additional documentation of experience from Eastern Europe and Africa could help fill knowledge gaps.,Countries had different national health plans outlining how to organize their systems and strategies for managing threats and hazards.Most countries reported some experience in implementing communicable disease surveillance as part of IHR (2005).,,Although complementary in nature, the preparedness and response core capacities were often implemented independently of one another. For example, areas requiring coordination across both of these core capacities, such as case management or infection control, were not well-documented. Taking a holistic approach to IHR (2005) core capacity development could avoid these issues.,,,Risk communication focuses primarily on effective communication strategies during disease epidemics. Some of the articles we identified primarily discussed communication systems.Global strategy on human resources for health: workforce 2030.,,The World Health Assembly recently approved the \u2013Laboratory networks are an essential part of national and regional health systems. Global laboratory networks are in place for polio, immunization programmes and influenza.\u2013,\u2013Given the many priorities in development, and limited national budgets to achieve them, external funding opportunities often help mobilize political commitment and national action. Experience from South Africa suggested that while external funding sources can be inflexible and unsustainable within national governance frameworks, such funding could create momentum in generating domestic financing and accelerate progress in implementing IHR (2005).,Along with financial and technical support, additional international measures could help accelerate IHR (2005) core capacity development. For example, since past disease epidemics affected regional and global economic growth, economic issues are relevant.This study has several limitations. We focused only on IHR (2005) core capacities and not on the core capabilities of points of entry, zoonotic events, food safety, chemical events and radiation emergencies.Despite considerable progress, countries that are yet to implement IHR (2005) core capacities may have insufficient human and financial resources to meet their obligations in the near future. Recent global epidemics have galvanized high-level political commitment towards ensuring global health security. We can leverage this commitment by mobilizing resources and securing wider collaboration to apply the lessons outlined here and accelerate the development of IHR (2005) core capacities globally."} +{"text": "Sholl analysis confirmed regular pattern of dendritic branching. The total length of dendrites was around 2100 \u03bcm with the average length of individual branching (intermediate) segment around 22 \u03bcm and for the terminal segment around 100 \u03bcm. Even though each experimental group underwent the same strictly defined protocol in tissue preparation and Golgi staining, we found inconsistency in dendritic volume and soma surface. These changes could be methodologically influenced during the Golgi procedure, although without affecting the dendritic length and tree complexity. Since the neuronal activity affects the dendritic thickness, it could not be excluded that observed volume inconsistency was related with functional states of neurons prior to animal sacrifice. Comprehensive analyses of tree complexity and dendritic length provided here could serve as an additional tool for understanding morphological variability in the most numerous neuronal population of the striatum. As reference values they could provide basic ground for comparisons with the results obtained in studies that use various models of genetically modified mice in explaining different pathological conditions that involve MSNs.In this study we have provided a detailed quantitative morphological analysis of medium spiny neurons (MSNs) in the mice dorsal striatum and determined the consistency of values among three groups of animals obtained in different set of experiments. Dendritic trees of 162 Golgi Cox (FD Rapid GolgiStain Kit) impregnated MSNs from 15 adult C57BL/6 mice were 3-dimensionally reconstructed using Neurolucida software, and parameters of dendritic morphology have been compared among experimental groups. The parameters of length and branching pattern did not show statistically significant difference and were highly consistent among groups. The average neuronal soma surface was between 160 \u03bcm The medium spiny neurons (MSNs) are the most numerous striatal neurons.

Pathological expression of mucins has been noted in cancer development and progression. This study sought to identify and quantify the types of mucins produced during various histological grades of colon cancer and to assess the diagnostic significance.Formalin fixed, paraffin-embedded tissue blocks, comprising three (3) normal colon and twenty-two (22) colon cancer tissues, were retrieved from the archives of the histopathology department of the Komfo Anokye Teaching Hospital. They were stained with Haematoxylin and eosin (H&E) for diagnosis and grading of tumours. Tissues were pre-digested with diastase and stained with Alcian blue (pH 2.5)/Periodic Acid Schiff to characterize the mucin variants present.Our findings indicated that normal colonic tissues expressed exceptionally high amount of acid mucin and low amount of neutral mucin. However, there was a general decrease in mucin expression in colon cancers compared to normal colon tissues. Additional findings suggested that as cancer progresses from low grade to high grade of adenocarcinoma of the colon, there was generally a considerable decrease in the acid mucin production and an increase in the neutral mucin expression. In contrast, a sizeable subpopulation of high-grade adenocarcinomas of colon showed a rather opposite mucin expression pattern- increase in acid mucin and a decrease in neutral mucin.As colonic cancer progresses, there are corresponding changes in the mucin types and content such that there are decrease in acid mucin and increase in neutral mucin expressions. Initiation and development of cancers, particularly colonic cancer is a very complex one with several variables playing crucial roles in sustaining the viability of the cancer. Even though initiations of colonic cancers are well attributed to genetic imbalances, which could be inherited or somatTwenty-five formalin fixed, paraffin embedded (FFPE) colonic tissues, which were retrieved from the archives of Histopathology Unit of the Department of Pathology, Komfo Anokye Teaching Hospital, Kumasi-Ghana, following ethical approval from both the hospital and Committee for Human Research, Publication and Ethics of School of Medical Sciences, KNUST. Two tissue sections at 3\u03bcm from each FFPE tissue block were produced. One batch of the sectioned FFPE colonic tissues was stained with Haematoxylin and Eosin (H&E) and were histologically diagnosed and graded by three independent pathologists. The second batch of the sectioned FFPE colonic tissues was dually stained with Alcian blue, pH 2.5 to demonstrate acidic mucins (sulfated and carboxylated) and Periodic Acid Schiff (PAS) to demonstrate glycogens and mucins. In order to exclusively demonstrate neutral mucins, dewaxed colonic sections were pretreated with diastase for 60 minutes to digest at existing glycogen in the tissue . PositivHaematoxylin and eosin (H&E) based diagnosis and grading colonic cancer tissues: Normal colon and colonic cancer tissues were H&E stained to confirm the diagnosis and grades of the tumours. Five of the 22 colonic cancers were diagnosed and graded as Grade 2, Well Differentiated Adenocarcinoma (G2WDA); 13 of the 22 colonic cancers as Grade 2, Moderately Differentiated Adenocarcinoma (G2MDA); 3 of the 22 colonic cancers as Grade 2 Adenocarcinomas (G2A) and only 1 case as Grade 3 Poorly Differentiated Adenocarcinoma (G3PDA) ( (G3PDA) . The colDifferential mucins staining with Alcian Blue/Diastase-Periodic Acid Schiff staining: in order to correlate the mucin content/amount and types with different grading of colonic cancers, we performed Alcian blue (pH 2.5)/Diastase-Periodic Acid Schiff staining. The sensitivity and specificity of the staining mucin staining were tested using appropriate controls. This was also part of the quality assurance procedure. Quality controls for mucin demonstration For a positive control, normal colon stained blue for acid mucins using Alcian Blue (pH 2.5), Diastase Periodic Acid Schiff (DPAS) staining on prostate, and DPAS/Alcian blue (pH 2.5) staining on colon (results not shown). For a negative control, liver tissues stained negative for Alcian Blue (pH 2.5), indicating absence of acid mucins, but stained magenta in DPAS, indicating the presence of neutral mucins. Further, an omission of the periodic acid oxidation step in DPAS resulted in a negative staining on human liver (results not shown).Mucin content/amount and types in colonic cancers: in this study, the total mucin content in 22 colonic cancer cases was semi-quantified after double Alcian blue (pH 2.5) and Diastase-PAS staining. The mucin types were also determined in each case. Both mucin content and types were estimated and correlated with tumour grade mucins but scanty neutral mucins;It is widely postulated that sulfated mucins play a role in the control of cell division;Production of mucins, in general, is remarkably reduced in adenocarcinomas of colorectal tissues.We, in this study, demonstrated that there is a progressive decline of acid mucin from low-graded to high graded adenocarcinoma of colorectal with corresponding increase in neutral mucins;We also demonstrated for the first time that a subgroup of moderately differentiated adenocarcinomas had rather an increase in acid mucins coupled with decrease neutral mucins in humans.The authors declare no competing interest."} +{"text": "Based on a two-end-member mixing model, all target consumers relied on energy sources from coupled benthic and planktonic pathways, but the predominant energy source for most species was highly variable across seasons, showing seasonal trophic shift of littoral consumers. Seasonality in energy mobilization of consumers focused on two aspects: (1) the species number of consumers that relied mainly on planktonic carbon showed the lowest values in the fall and the highest during spring/summer, and (2) most consumer species showed seasonal variation in the percentages of planktonic reliance. We concluded that seasonal trophic shifts of fishes and invertebrates were driven by phytoplankton production, but benthic resources were also important seasonally in supporting littoral consumers in Meiliang Bay. Energy mobilization of carnivorous fishes was more subject to the impact of resource availability than omnivorous species.We evaluated the seasonal variation in the contributions of planktonic and benthic resources to 11 littoral predators in eutrophic Lake Taihu (China) from 2004 to 2005.

Recent studies have demonstrated that abnormalities in DNA methylation may underlie the alterations in various indicators of GABAergic and glutamatergic functions in schizophrenia. As our group previously found decreased NR2 protein plasma levels and downregulation of parvalbumin (PVALB) mRNA in first episode of psychosis (FEP) patients, we hypothesised that changes in DNA methylation may be responsible for these indicators of glutamatergic and GABAergic deficits in FEP patients.Blood samples were collected from patients in FEP (n = 35) after their first contact with the mental health assistance, siblings (n = 21) and population-based controls (n = 35). Bisulfite conversion and pyrosequencing were used to determine methylation levels in 4 CpG sites in promoter sequence of PVALB and 5 CpG sites at GRIN2B (gene which encodes NR2).We found hypermethylation at a CpG site within the PVALB promoter sequence in patients and their siblings compared to population-based control group (p< 0.001) while overall hypomethylation was found in the 5 CpGs analysed within GRIN2B promoter sequence (p < 0.01).Our PVALB findings are consistent with our previous studies showing that PVALB promoter methylation is elevated in schizophrenia and, additionally this is the first evidence showing changes in GRIN2B promoter methylation in psychosis.

To estimate the risk of PDC occurrence in children with dental anomalies identified early during mixed dentition. The sample comprised 730 longitudinal orthodontic records from children with an initial mean age of 8.3 years (SD=1.36). The dental anomaly group (DA) included 263 records of patients with at least one dental anomaly identified in the initial or middle mixed dentition. The non-dental anomaly group (NDA) was composed of 467 records of patients with no dental anomalies. The occurrence of PDC in both groups was diagnosed using panoramic and periapical radiographs taken in the late mixed dentition or early permanent dentition. The prevalence of PDC in patients with and without early diagnosed dental anomalies was compared using the chi-square test (p<0.01), relative risk assessments (RR), and positive and negative predictive values (PPV and NPV). PDC frequency was 16.35% and 6.2% in DA and NDA groups, respectively. A statistically significant difference was observed between groups (p<0.01), with greater risk of PDC development in the DA group (RR=2.63). The PPV and NPV was 16% and 93%, respectively. Small maxillary lateral incisors, deciduous molar infraocclusion, and mandibular second premolar distoangulation were associated with PDC. Children with dental anomalies diagnosed during early mixed dentition have an approximately two and a half fold increased risk of developing PDC during late mixed dentition compared with children without dental anomalies. According to the guidance theory, local conditions, such as maxillary lateral incisor agenesis or microdontia, are related to canine displacement,,,,,The study by Sacerdoti and Baccetti,-,Ectopic eruption of maxillary canines has two major clinical concerns: the consequent impaction of the canine and the possibility of incisor external root resorption,,,Conversely, when there is an early orthodontic diagnosis of PDC, simpler clinical approaches such as deciduous canine extraction and rapid maxillary expansion can lead to spontaneous canine eruption in a high percentage of childrenThis retrospective longitudinal study was approved by the Research Ethical Committee of the Hospital for Rehabilitation of Craniofacial Anomalies, University of S\u00e3o Paulo (HRAC-USP) (379/2010). The patient records were anonymized and de-identified prior to analysis. The initial sample was composed of the orthodontic files of 810 children treated from 1980 to 2005 at the Society for the Social Promotion of Cleft Lip and Palate Patients (PROFIS). Inclusion criteria were: presence of an initial panoramic radiograph taken during the first transitional period or inter-transitional period of mixed dentition, according to the Van der LindenThe final sample was composed of 730 orthodontic records from children with an initial mean age of 8.3 years (SD=1.36), from both genders . A rough estimate of the ethnic background of the sample based on facial photograph was: White (84%), Black (12%), and Asian (4%). The experimental and control groups included 263 and 467 records, respectively, and were composed based on the analyses of the initial panoramic radiographs and dental casts to investigate the presence of the following dental anomalies: 1. Agenesis of any permanent teeth, except for third molars; 2. Microdontia of maxillary lateral incisors; 3. Infraocclusion of deciduous molars; 4. Distoangulation of mandibular second premolars; 5. Tooth transpositions.All the records were analyzed by a single calibrated examiner (ML). The examiner was precalibrated showing an agreement index ranging from 90 to 100% (Kappa test). The maxillary lateral incisor was considered as presenting microdontia when the maximum mesiodistal crown diameter was smaller than the same dimension of the opposing mandibular lateral incisor in the same patient, using the dental castsThe sample was divided into two groups. The dental anomaly group (DA) was composed of 263 patients with at least one dental anomaly identified in the initial or middle mixed dentition. Records from children without these dental anomalies in the early/middle mixed dentition (n=467) composed the non-dental anomaly group (NDA). Age and gender distribution in both groups is presented in Panoramic radiographs from late mixed dentition and/or early permanent dentition were evaluated to assess risks for the development of PDC in both groups. Considering the findings of Ericson and KurolThe frequency of PDC development was calculated in DA and NDA groups. Intergroup comparisons were performed using the Chi-square test with a significance level of 5%. In order to measure the strength of associations between occurrences of early-diagnosed dental anomalies and PDC, the relative risk (RR) at the 95% confidence interval and the positive and negative predictive values (PPV and NPV) were calculated. Additionally, the frequency of PDC development was separately calculated for each dental anomaly and compared with the control group using the Chi-square test (p<0.01) and relative risk assessment.Seventy-two individuals were affected by PDC (9.86%) with a male:female ratio of 1:3 in the combined DA and NDA groups (n=730). In this subgroup of individuals with PDC, 29.1% (n=21) showed bilateral expression, 31.9% (n=23) unilateral right expression, and 38.9% (n=28) unilateral left expression.The DA group presented PDC frequency of 16.3% compared with 6.2% of the NDA group .

Peck, PA limitation of this study is the possibility of false-positive diagnosis for PDC using panoramic radiographs,Our results show that small maxillary lateral incisors, distoangulation of mandibular second premolar, and deciduous molar infraocclusion are early risk markers for PDC. Pediatric and orthodontic population with such dental anomalies diagnosed during the early mixed dentition should be carefully monitored during the critical age period for early diagnosis and intervention of maxillary canine ectopic eruption. The recognition of risk markers for the occurrence of PDC can increase the possibility of early diagnosis and intervention. Future longitudinal studies could contribute to identify other potential risk indicators for PDC including family history, female gender, hypodivergent pattern, and enamel hypoplasiaChildren with some dental anomalies diagnosed during the early mixed dentition have an approximately two and a half fold increase in risk of developing PDC during the late mixed dentition compared with children without these dental anomalies. Microdontia of maxillary lateral incisors, mandibular second premolars distoangulation, and deciduous molar infraocclusion constitute early risk markers for PDC development.

Recent advances in our understanding of the critical roles of DNA methylation, histone modifications and ncRNA may now be exploited to improve management of fibrosis/cirrhosis and cancer. Furthermore, improved technologies for the detection of epigenetic markers from patients' blood and tissues will vastly improve diagnosis, treatment options and prognostic tracking. The aim of this review is to present recent findings from the field of liver epigenetics and to explore their potential for translation into therapeutics to prevent disease promoting epigenome reprogramming and reverse epigenetic changes. If taken literally this could include all of the events involved in the regulation of gene expression. However for the purpose of this review discussion will be limited to those regulatory mechanisms that operate at the level of DNA methylation, histone modifications and the activities on non-coding regulatory RNA molecules. But in addition, readers should be aware of the critical role that transcription factors play in determining gene expression and cell phenotype. Transcription factors, which operate by recognising specific DNA motifs in the promoter/enhancer regions of genes and then modulate the activity of RNA polymerase II, are increasingly featuring as important drug targets in chronic liver disease. Typical examples being the peroxisome proliferator-activated receptors and the farnesoid X receptor for which ongoing clinical trials are determining efficacy in non-alcoholic fatty liver disease (NAFLD) and autoimmune liver disease de novo methyltransferases, establishing methylation patterns during development DNA methylation is a direct chemical modification of DNA in which methyl groups are predominantly added to cytosine residues within the context of a CpG dinucleotide DNA is packaged into chromatin of which the unit structure is the nucleosome which is comprised of two copies each of histones H2A, H2B, H3 and H4 that assemble into an octamer around which 146\u2013147\u00a0bp of DNA is tightly wrapped. The nucleosome is a highly dynamic structure and dictates the degree to which DNA is accessible for transcription; this being determined by its degree of compaction and by post-translational modifications (PTMs) on the N-terminal tails of its constituent histones The vast majority of the human genome is transcribed, however only 2% encodes proteins. The vast majority of the transcriptome consists of non-coding RNAs (ncRNAs) that have regulatory functions and include micro RNAs (miRNA), small nucleolar RNAs (snoRNAs), small interfering RNAs (siRNAs), Piwi-interacting RNAs (piRNAs) and the long non-coding RNAs (lncRNAs). The miRNAs are an extensively studied class of single-stranded 18\u201322 nucleotide ncRNAs that fine-tune expression of the genome either by decreasing the stability or suppressing translation of messenger RNAs Here we will consider recent advances in the role of DNA methylation, histone modifications and ncRNAs in chronic liver diseases and in particular how new knowledge of these epigenetic mechanisms may be exploited for improving the management of the two major liver disease endpoints, fibrosis/cirrhosis and cancer.2The liver must adapt on a daily basis to a constant flux of environmental variations including circadian oscillators, nutritional/metabolic fluxes, exposure to xenobiotics, viral infections, alterations in the microbiome and the demands for epithelial repair and regeneration. Using a deep sequencing approach, Vollmers and colleagues systematically mapped the epigenetic changes occurring over 24\u00a0h in the mouse liver via its induction of hepatic reactive oxygen species (ROS) promotes H3K9 acetylation leading to increased expression of alcohol-metabolising enzymes that induce further ROS and acetylation potentially establishing feed-forward epigenetic re-landscaping HDAC3 is an important circadian regulated epigenetic writer critical for hepatic triglyceride homoeostasis and when deleted in mice results in steatosis, inflammation and fibrosis via its ability to influence DNMT activity and in addition recruits the histone acetyltransferases p300/CBP to induce IL-8 and proliferating cell nuclear antigen (PCNA) which are involved in inflammation and cell proliferation respectively Hepatitis C virus (HCV) infection promotes multiple changes in DNA methylation including at enhancer elements associated with altered expression of genes implicated in cancer and control of stem cells Hence, in summary the epigenetic landscape of the liver is acutely sensitive to environmental cues resulting in modifications that impact on its circadian controlled patterns of gene expression. In obesity and alcoholic disease the disturbance to the hepatic epigenetic landscape may promote microenvironments in which steatosis advances to inflammation, fibrosis and cancer.3Myofibroblasts are the major cellular drivers of liver fibrosis and appear during conditions of liver damage and/or infection mainly through the process of hepatic stellate cell (HSC) transdifferentiation. The conversion of quiescent HSC to their activated myofibroblast state involves vast changes in transcriptome expression that dramatically alter the phenotype and behaviour of the cell. In the past decade we have begun to shed light on the epigenetic events that reprogram the HSC transcriptome, thus revealing new regulators of fibrogenesis as well as potential biomarkers for tracking disease progression.3.1in-vivo transdifferentiation of HSC can be recapitulated in a cell culture model in which isolated HSC are maintained for several days on plastic in serum-containing media. In this widely used model, HSC transdifferentiation was accompanied by a >\u00a020% methylation change (hypo- or hyper-methylation) in ~\u00a0400 methylated regions including DNMT3A and DNMT3B 4) induced liver fibrosis 4 mouse fibrosis model Many of the regulatory events associated with DNA methylation in the PPAR\u03b3 gene promotor has also been shown to be relevant in human disease. In a well phenotyped cohort of patients with biopsy proven NAFLD Zeybel et al. demonstrated that hypermethylation at discreet CpG dinucleotides within the human PPAR\u03b3 gene promotor could be used to stratify patients with mild fibrosis (Kleiner score 0\u20132) from those with severe fibrosis (Kleiner score 3\u20134) in vivo models of chronic liver disease (bile duct ligation (BDL), CCl4 and methionine-choline deficient (MCD) diet) de novo methyltransferases DNMT3A/B expression, diminution of TET protein expression and remodeling of the HSC DNA methylome. Moreover, culture activated HSC and ex-vivo purified HSC from CCl4 injured rats also demonstrated increased DNMT3A and DNMT3B, with knock-down of the latter enzymes resulting in reduced fibrogenic features. Of note, similar fibrosis-associated epigenetic changes were observed in mechanistically distinct examples of chronic human liver disease supporting the concept that fibrosis is in part driven by alterations in the balance between the DNMTs and TETs As previously explained DNA methylation is a dynamic epigenetic marker that is regulated by DNMT and TET enzymes that stimulate CpG methylation and demethylation respectively 3.2Schistosoma mansoni and BDL induced liver fibrosis in vivo delivery of histone methyltransferase inhibitors to HSC can potently inhibit liver fibrosis 4-induced liver damage in vivoHistone acetylation is associated with active transcription and is under the control of HATs and HDACs. Niki et al. first described the anti-fibrotic effects of HDAC inhibitors showing that trichostatin A (TSA) treatment of cultured HSC suppressed fibrogenic gene expression and proliferation 3.34 exposure or BDL, this observation being confirmed in human liver with advanced fibrosis in vivo relevance in vivo and in vitro during liver fibrosis, with HOTAIR knockdown suppressing HSC activation. The authors further demonstrated that HOTAIR downregulates miR-29b expression, attenuating its control on epigenetic regulation, leading to enhanced phosphatase and tensin homolog (PTEN) methylation, which contributes to the progression of liver fibrosis A large number of miRNAs have been described that both promote and suppress HSC transdifferentiation 4Hepatocellular carcinoma (HCC) is the 3rd leading cause of cancer deaths worldwide and treatment options are severely limited. There is a clear need for the identification of the molecular drivers of HCC if progress is to be made in developing new medicines. Deep sequencing studies have been instrumental in identifying gene mutations and potential disease drivers in HCC. Alongside these genetic approaches is an increasing awareness of the role of epigenetic regulators in HCC which have strong potential for drug and biomarker design.4.1DNA methylation changes are common in human cancers and it was therefore unsurprising that 3700 hypomethylated promoters were identified in HCC tumour samples in vivo. Reduced SMPD3 expression was associated with early HCC recurrence following resection in vivo in a xenograft HCC HepG2 model. CDKN2A, DLEC1 and RUNX3 promoters were all confirmed to be demethylated in HCC lines following Guadecitabine treatment and correlated with inhibition of cell growth. Importantly, in contrast to decitabine, Guadecitabine was able to overcome the inhibitory effects on cell growth by macroH2A1 (variant of histone H2A), highlighting Guadecitabine as a potential HCC therapeutic, particularly in advanced disease There is vast potential for alterations in DNA methylation in HCC to be exploited for future drug and biomarker development. The de-methylating agent decitabine has been used to validate the expression of hypermethylated TSG in primary HCC and also re-expression of genes in HCC cell lines. 13 candidate TSG were identified in this study including DGK1, LDHB, NEFH, SMPD3, ACTL6B and PRPH. Functional characterisation of 2 candidates, SMPD3 and NEFH, revealed that overexpression leads to inhibition of cell proliferation, whereas by contrast knockdown increased tumour formation 4.2in vitro and in vivoHistone modifying enzymes offer much promise for HCC therapy since they are tractable targets for the design of small molecule inhibitors. The H3K27 methylase EZH2 is up-regulated in HCC tissue and is associated with cancer progression, invasion and proliferation 4.3Previous and emerging studies in HCC are now beginning to incorporate ncRNAs into our molecular understanding of HCC pathogenesis and progression As the complexity of these molecular interactions unravel, we can begin to appreciate that in most scenarios these modulators likely work together as a network of epigenetic regulators. This highlighted by a study demonstrating how HULC and MALAT1 combine in complex with TRF2 to significantly increase telomerase activity and microsatellite instability in liver cancer stem cells NCT02603224).Therapeutic targeting of ncRNA in HCC is now an imminent challenge. Emerging pre-clinical studies utilizing sophisticated drug delivery nanoparticles and animal proof of concept models such as this study successfully targeting the lncRNA TUG1 show promise for therapeutic development of antisense oligonucleotides 5The hepatic epigenome is remarkable in its capacity to adapt to dietary, metabolic, xenobiotic and microbial challenges in order to maintain cellular and functional homeostasis. However, when this capacity is breached epigenetic adaptions can become problematic and contribute to disease pathogenesis. We are now aware of how key components of the epigenetic machinery such as DNA methylation, histone PTMs and ncRNAs alter their expression or function in the context of fibrosis/cirrhosis and liver cancer. The next steps are to convert this information into bespoke medicines that either prevent disease-driving epigenome reprogramming or that reverse specific disease-promoting epigenetic changes. Furthermore there is vast potential to use the appearance of liver-derived epigenetic markers in the patient circulation for the diagnosis and prognostic tracking of chronic liver disease using no more than a few drops of blood, avoiding the need for biopsy or complex and expensive imaging modalities."} +{"text": "Scientific Reports6: Article number: 34474; 10.1038/srep34474 published online: 09292016; updated: 05082017.As the authors of references 25 and 26 also employed plasma-assisted molecular beam epitaxy for the synthesis of hexagonal boron nitride films, the authors would like to make the following changes to the Introduction section of their Article:23,24,25,26 and atomic layer deposition27 of hBN on metal substrates; this approach must typically be complemented by complex protocols for the removal and transfer of the grown films\u201d.\u201cIn addition the direct growth of hBN on a two-dimensional material (HOPG) offers an alternative to chemical vapour depositionShould read:23,24, MBE25,26 and atomic layer deposition27 of hBN on metal substrates; this approach must typically be complemented by complex protocols for the removal and transfer of the grown films\u201d.\u201cIn addition the direct growth of hBN on a two-dimensional material (HOPG) offers an alternative to chemical vapour deposition"} +{"text": "The variables were related to brightness, color, physical aspects, soluble and total collagen as well as chemical traits.

The effect of physiological stages on the quality of meat was accessed using 16 variables measured in the The Midwest of Brazil presents the highest growth rates of sheep farming in the country . This reSeveral factors limit sheep breeding to play a more significant role on rural development and become a source of financial income in developing countries such as Brazil , 3. The Progress has been reported, but market and merchandising of sheep products in many developing countries still contrast with global market trends which requires urgent adjustments \u201313There is considerable lack of information regarding breed, geographical provenance, breeding system and traceability of age category , which may denote the quality of meat after slaughter.Food originated from indigenous breeds of sheep is an option to access and develop alternative markets \u201316. HoweIt is reasonable to consider that the diversification of products and market niches require efforts towards characterization , 19\u201321. The quality of meat has been an important subject , includiStill, in countries such as Brazil, three top products derive from sheep farming: meat from lambs (a), wethers (b) and cull ewes (c). Demands for each one of these products vary according to local market trends in different macro regions of South American countries . PhysicoConsidering some of the aspects of indigenous sheep farming, this study was designed to generate a first report on meat quality of Pantaneiro sheep, encompassing physicochemical and sensory characterization of the most common physiological stages commercialized in South American sheep industries.All protocols of experimental procedures were approved by the Animal Experimentation Ethics Committee (CEUA) of the Federal University of Grande Dourados (UFGD), The criteria to slaughter lambs (a) and wethers (b) was the body condition, which ranged from 2.5 to 3.0 .

Lambs (Cynodon spp. (Tifton85) and supplemented (1% of body weight) with the same concentrate used for lambs (water ad libitum). These animals were slaughtered at the age of 12.5\u00b11.18 months. The cull ewes (c) were kept in extensive systems with tropical pastures of Brachiaria brizantha cv. Piat\u00e3 with ad libitum mineral salt. Cull ewes (c) were slaughtered at the age of 68\u00b113 months (The wethers (b) were kept in tropical pastures based on 3 months .All animals were slaughtered after 16-hours of fasting (solids). Desensitization was carried out by electronarcosis (8 seconds of 220-V discharge) followed by cutting of jugular veins and carotid arteries with subsequent evisceration. Lambs (a), wethers (b) and cull ewes (c) showed initial average weight of 19.64, 19.90 and 45.04 kg, respectively. Final average weight was 35.72, 43.04 and 49.58 kg, respectively longissimus thoracis et lumborum (LM) and semimembranosus (SM) muscles were removed for meat quality analysis. All samples were analyzed with one replicate, and the final value of each variable was determined calculating a simple average for each variable.After slaughter, the carcasses were stored in a cold room at 4\u00b0C during 24 hours. Subsequently, the Evaluation of meat was performed based on color, physical characteristics, soluble and total collagen and chemical characteristics Tables The color was evaluated in lyophilized samples, submitted to acid digestion, filtration, neutralization, dilution and oxidation for colorimetric reaction. The results were based on the hydroxyproline values from absorbance readings performed in a spectrophotometer with a wavelength of 570 nm. The sample color was evaluated after 30 minutes of exposure to air to allow myoglobin reaction with oxygen . BrightnThe physical characteristics of meat were evaluated regarding water retention capacity (%) according to the method described by . The sheThe pH and temperature of the warm and the cold carcass were monitored using a digital thermometer and pH-meter with a Testo 205/206 penetration probe.

Total nlongissimusthoracis et lumborum (LM) and semimembranosus (SM) muscles. This was done using a univariate approach (PROC GLM) (p<0.05). Analyses were performed using the software SAS 9.2 . A multivariate method was used to standardize data (PROC STANDARD procedure) and to develop clustering analysis (PROC FASTCLUS procedure) assuming three clusters.The experimental design was arranged as an exploratory study. Animals were sampled from an on farm conservation flock and sorted according to pre-established physiological stages. The Shapiro-Wilk test was performed to verify the residue data normality, and the Bartlett test was performed to verify homogeneity of variances. Similar to a nested analysis approach, the effect of physiological stages (fixed effect) (lambs (a), wethers (b) and cull ewes(c)) was evaluated on the versus SM) regarding each physiological stage (The meat from lambs (a) showed different values compared with cull ewes (c) with only one exception of the LM muscle al stage . Means bWater retention capacity, shear force and losses of weight after cooking presented similar averages (P>0.05) between physiological stages The highest concentration of total collagen was found in the meat from cull ewes. Physiological stages presented different values of total collagen All variables related to chemical composition were effected (P<0.05) by the physiological stage. The chemical analysis showed significant differences between means of lambs and cull ewes, except for the ash content of the SM muscle.The meat from wethers showed the same ether extract content than the cull ewes, regardless of the muscle type Lambs showed greater moisture content in the LM muscle Considering all 15 variables used to evaluate the quality of meat from different physiological stages, only three variables may present similar aspects to the meat of lambs (a). The meat of some cull ewes (c) maybe similar to the meat of wethers (b). However, no cull ewes (c) presented similar meat quality compared to lambs (a) In general, the variables related to brightness (L*), the intensity of yellow (b*) and red (a*) varied according to physiological stages There is a trend to believe that many physical aspects of meat vary according to the age of animals at slaughter , 40. AgiCarcasses from older animals are associated to greater stability and texture of muscle fiber showing less soluble collagen . The samIn general, meat from different physiological stages showed appropriate quality values of collagen and pH, configuring soft meat The chemical characteristics of meat also differed between physiological stages The variation of meat quality regarding muscle types was considered to be random. However, diversifying aspects related to flavor and nutritional aspects of indigenous sheep meat was observed between different physiological stages.Fine discrimination observed with multivariate analysis Evaluation of meat from indigenous Pantaneiro sheep of different sex and physiological stages revealed suitable standards of meat quality produced in a rough and typically unique tropical ecosystem. Notable differences were observed between the quality of meat originated from lambs and cull ewes. This fine discrimination opens the door to valuable validation of how meat quality relates to sensorial aspects and consumer preferences regarding the preparation of dishes and consumption.Characterization of food products derived from locally adapted livestock in developing countries is an effort towards the development of new products with added value which may enhance merchandising, marketing strategies and consumption.S1 FileProtocols of experimental procedures were approved by commuittes(PDF)Click here for additional data file."} +{"text": "Data presented within this article supports the findings of the manuscript \u201cA systematic review of fantasy driven vs contact driven internet-initiated sexual offences: Discrete or overlapping typologies?\u201d [1].

It is important to understand how using fresher stored red blood cell units for certain patient groups may affect blood availability.Based on the Stock-and-Flow simulation model of the US blood supply developed by Simonetti et al. 2014, we evaluated a newly implemented allocation method of preferentially transfusing fresher stored red blood cell units to a subset of high-risk group of critically ill patients and its potential impact on supply.Simulation results showed that, depending on the scenario, the US blood total supply might be reduced between 2-42%, when compared to the standard of care in transfusion medicine practice. Among our simulated scenarios, we observed that the number of expired red blood cell units modulated the supply levels. The age threshold of the required red blood cell units was inversely correlated with both the supply levels and the number of transfused units that failed to meet that age threshold.To our knowledge, this study represents the first attempt to develop a comprehensive framework to evaluate the impact of preferentially transfusing fresher stored red blood cells to the higher-risk critically ill patients on supply. Model results show the difficulties to identify an optimal scenario. Observational studies have estimated the effects of red blood cell (RBC) storage time on clinical outcomes among different patient groups.

Risk of bias for HR estimates was assessed using prespecified criteria for the appraisal of relevant domains as defined by the Cochrane Prognosis Methods Group including adherence to Grading of Recommendations, Assessment, Development and Evaluation and REporting recommendations for tumor MARKer prognostic studies guidelines, as well as assay method used (direct TP53 mutation assessment vs immunohistochemistry) and adjustment for standard prognostic factors. A pooled HR and 95% CI were calculated using a random-effects model.2=33%). A greater prognostic effect was observed in a sensitivity analysis of those studies that reported survival for OAC-only cohorts and were assessed at low risk of bias .Sixteen eligible studies (11 with OAC only and 5 mixed histology cohorts) including 888 patients were identified. TP53 mutations were associated with reduced survival (HR 1.48, 95% CI 1.16 to 1.90, IPatients with OAC and TP53 gene mutations have reduced overall survival compared with patients without these mutations, and this effect is independent of tumour stage. Oesophageal adenocarcinoma (OAC) remains one of the few GI malignancies where molecular information is not taken into account to guide patient management.Current clinicopathological staging fails to accurately identify patients with OAC with good or poor prognosis.Recent genomic findings have identified a high tumour protein 53 (TP53) mutation rate in OAC, but the prognostic impact of this remains unclear due to conflicting reports in the literature.This is the first dedicated systematic review and meta-analysis regarding the prognostic impact of TP53 mutations in patients with OAC including 16 studies with >850 patients.We identify a significant negative prognostic impact of TP53 mutations on overall survival of patients with OAC.A greater prognostic effect can be corroborated in studies that report tumour-stage adjusted survival for OAC-only cohorts and are assessed at being at low risk of bias.This study suggests that TP53 gene mutations have a clinically important negative prognostic impact on patients with OAC.In light of recent genomic findings highlighting a central role of this gene in OAC pathogenesis and drugs currently in development and testing that directly target this gene, a role for identifying TP53 mutations in OAC can be suggested.The incidence of oesophageal adenocarcinoma (OAC) has increased faster than any other cancer since the 1970s in many Western countries with highest incidence rates found in Northern and Western Europe, Northern America and Oceania,Fewer than half of the patients with a new diagnosis of OAC are eligible for curative treatment, and OAC continues to have one of the highest cancer case-fatality rates with population-based 5-year survival rates typically around 15%.The tumour-suppressor gene tumour protein 53 (TP53) , which encodes the p53 protein and is sometimes called \u2018the guardian of the genome\u2019,18Recent large-scale whole-genome and whole-exome sequencing studies have shown that both OAC and dysplastic BO harbour a very high TP53 mutation rate of up to 70%,We aimed to resolve the existing uncertainty regarding the prognostic value of TP53 for staging OAC by conducting a systematic review and meta-analysis of all published data with subgroup analysis of studies assessed as low risk of bias, and studies using direct TP53 gene mutation analysis techniques to determine TP53 mutation status, since these are the most accurate methods for determining tumoural TP53 mutations.Gastroenterology), American Society for Clinical Oncology and American Association for Cancer Research from 1990 to 2015.The electronic bibliographic databases MEDLINE, Embase, PubMed and Current Contents Connect were searched to identify eligible studies published between January 1990 and 8 February 2015 using MeSH terms and text words for adenocarcinoma*, o/esophagus* or o/esophageal*, TP53* or p53* or 17p13* or 17p*. In an attempt to minimize the risk of publication bias, conference abstracts and proceedings were searched through Web of Science, Embase and Scopus using the terms o/esophagus* and p53*. Further, the following major GI and oncological conferences were searched for relevant reports: Digestive Disease Week scanned the search results (title and abstract) and retrieved full text publications using the criteria outlined below to identify eligible studies. Reference lists of relevant studies identified from the search including reviews were further screened to identify studies that may not have been identified by the strategy outlined above.Study inclusion criteria were prospective or retrospective clinical studies of OAC populations that assessed TP53 mutation status and/or p53 expression in primary tumours, and compared overall survival for TP53 mutation versus TP53 non-mutation subgroups with calculation of HR and 95% CIs, or reported adequate data for their estimation. To include all available data, we also included studies of oesophageal cancer cohorts that included patients with squamous cell carcinoma if at least \u226550% of the patient cohort had a diagnosis of OAC.Study exclusion criteria were studies of TP53 DNA germline mutations or autoantibody detection in blood; and reports available in abstract form only that did not report adequate information to determine study eligibility or to assess study methods for risk of bias.If studies did not report sufficient data to calculate HRs or in case of missing/unclear data, the corresponding author was contacted by email to request this information. If the same research unit (identified from author names and institution) published multiple reports with overlapping patient recruitment time periods, HR estimates were extracted from the most recent publication with the largest patient numbers to avoid duplication of data.Three investigators reviewed eligible studies and extracted the following variables into a standardised data extraction form: author's name; publication year; country where study was conducted; number of patients included and general patient demographics; tumour histology (number and proportion of OAC tumours included); treatment modality ; tissue specimen type ; TP53 assay methods , immunohistochemistry (IHC), and type of antibody, dilution for IHC); criteria or cut-point used to define TP53 mutation status for the survival analysis; study prevalence of TP53 \u2018mutation\u2019 and \u2018non-mutation\u2019 subgroups; median survival of all patients and by TP53 mutation status; unadjusted and adjusted HR with 95% CI and corresponding p values where available. For consistency and to facilitate further quantitative analyses, the authors\u2019 definitions for TP53 \u2018mutations\u2019 were used for studies performing only IHC as the respective studies did not use uniform staining classification criteria. As such, nuclear p53 protein overexpression was interpreted to represent TP53 mutations by all authors of the included studies, although loss of p53 protein expression has also been associated with tumoural TP53 gene mutations.http://www.gradeworkinggroup.org),et al's27All studies were assessed for risk of bias for the study estimate of the impact of TP53 on survival by appraising six domains using prespecified criteria adapted from the Grading of Recommendations, Assessment, Development and Evaluation TP53 mutation database (R17)10.1136/gutjnl-2015-310888.supp1Supplementary materialsTo estimate the effect of TP53 mutation status on OAC survival, we calculated a pooled HR and 95% CI using the generic inverse variance method.

Differences between subgroups were assessed with a test for interaction.34ggplot2 package.metafor and forestplot for R.38Descriptive statistics as well as quantitative analysis of the IARC TP53 mutation database to guide risk of bias assessment were performed using R statistical softwareThe search strategy yielded 323 studies, of which 16 met our eligibility criteria . Study cHalf of the studies (n=8) assessed TP53 mutation status by IHC,The clinicopathological variables and survival times reported in the included studies are summarised in HRs were reported in nine studies and extrapolated from five studies. In addition, individual patient data were available for two studies to calculate tumour stage-adjusted HR and 95% CIsFour studies2=33%, p heterogeneity=0.1). The analysis of studies including pure OAC patient cohorts showed similar results with low heterogeneity compared with studies performing direct TP53 gene assessments (sequencing and SSCP) or LOH analyses . This difference was borderline statistically significant (p for interaction=0.05). A similar effect was seen in the subset of studies containing pure OAC cohorts . This effect size was similar in the three studies with low risk of bias that contained pure OAC cohorts and the study appraised as being at low risk of bias were significant sources of heterogeneity .This study indicates that mutated TP53 negatively impacts overall survival in patients with OAC, independent of tumour stage. This effect is estimated as a relative increase in hazard of death of 48%, with up to a 211% increase when studies of mixed histology cohorts or high risk of bias are excluded. This corresponds to a reduced survival time of approximately 7\u2005months based on median survival from the included studies. This effect size is similar to the difference in median survival of stage IIIA compared with stage IIIC OAC.55To our knowledge, this is the first comprehensive systematic review and meta-analysis of the prognostic impact of TP53 mutations in patients with OAC that includes an assessment independent of tumour stage. Two previous systematic reviews and meta-analyses of various prognostic biomarkers in OAC have included an analysis of TP53 mutations.This study is timely because recent whole-genome sequencing studies have shown a high mutation rate of TP53 in OAC.58One potential explanation for earlier conflicting results for the prognostic significance of TP53 status in OAC is the use of different and potentially less accurate assay methods for TP53 mutation detection. Our study identified considerable variability in IHC methods across the included studies, such as the use of different antibodies, antibody dilutions and variable scoring systems for immunopositivity. Further, none of the included studies used loss of p53 expression as a method for interpreting the presence of TP53 gene mutations.22Recent genomic studies have found that TP53 gene mutations remain the most common genetic alteration in both OACet al,The two main limitations of this study that may affect the validity of our findings are the quality of the primary studies and data limitations to explore potential confounders.

Moreover, multiple therapeutic options directly targeting the TP53 gene are either currently in clinical trials or are already clinically available.One approach to collect high-quality data is to include TP53 mutation analysis using targeted gene sequencing in the baseline analysis of trials of OAC therapies. If validated, TP53 analysis could be used to stratify patients in future trials. Stratifying patients based on TP53 mutation status may also have a role in clinical practice to guide treatment selection. For example, data suggest that TP53 mutation status may predict response to standard chemotherapeutic regimens such as fluorouracil or cisplatin,In summary, OAC remains one of the few GI malignancies for which molecular information is still not used to guide patient management. This study suggests that TP53 gene mutations have a clinically important negative prognostic impact on patients with OAC, which is relevant in light of recent genomic findings highlighting a central role of this gene in OAC pathogenesis and drugs currently in development and testing that directly target this gene. High-quality studies with large patient cohorts using modern sequencing technologies for TP53 mutation analysis are needed to confirm the independent prognostic effect of this frequent gene mutation."} +{"text": "This data aimed to audit the dental sciences related articles published in Iranian Journal of Basic Medical Sciences (IJBMS) from 2007 to 2015 over a 9 year period performed using web-based search.

This year, DOHMH noted an increase in HAV infections among MSM with onsets in January\u2013March 2017, and notified other public health jurisdictions via Epi-X, CDC\u2019s communication exchange network. As a result, 51 patients with HAV infection involving MSM were linked to the increase in NYC.Confirmed cases were defined as symptomatic HAV infections with onset after December 31, 2016, in NYC residents who reported being MSM or having sexual contact with MSM, and reported no travel to areas of high or intermediate HAV endemicity. Probable cases were defined as onset of symptomatic HAV infection after December 31, 2016, in NYC residents who, irrespective of travel, reported being MSM or having sexual contact with MSM. For the period January 1\u2013August 31, 2017, DOHMH identified 46 cases in MSM or persons with sexual contact with MSM; 36 confirmed and nine probable cases occurred in 45 MSM patients and one was in a female (confirmed case) who reported sexual contact with a bisexual male resident of a New York county outside New York City. Fifteen (33%) of the 46 patients were hospitalized, and three (7%) reported previous receipt of hepatitis A vaccine. Nineteen (41%) patients had traveled domestically during their incubation period, and eight (17%) had traveled to Western European countries where outbreaks of HAV infection among MSM are ongoing (NYC routine surveillance identified another case of HAV infection (in addition to the 46 NYC patients), in a man who was hospitalized in New York City but resided in the New York county that had been visited by the female patient. Several Colorado jurisdictions also contacted DOHMH to report increases in HAV infections among MSM.

This single nucleotide substitution causes a truncation of the ssTnT protein at Glu180 and the loss of the C-terminal tropomyosin (Tm)-binding site 2. As a consequence, it abolishes the myofilament integration of ssTnT and the loss of function causes an autosomal recessive nemaline myopathy (NM). More TNNT1 mutations have recently been reported in non-Amish ethnic groups with similar recessive NM phenotypes. A nonsense mutation in exon 9 truncates ssTnT at Ser108, deleting Tm-binding site 2 and a part of the middle region Tm-binding site 1. Two splicing site mutations result in truncation of ssTnT at Leu203 or deletion of the exon 14-encoded C-terminal end segment. Another splicing mutation causes an internal deletion of the 39 amino acids encoded by exon 8, partially damaging Tm-binding site 1. The three splicing mutations of TNNT1 all preserve the high affinity Tm-binding site 2 but still present recessive NM phenotypes. The molecular mechanisms for these mutations to cause myopathy provide interesting models to study and understand the structure-function relationship of TnT. This focused review summarizes the current knowledge of TnT isoform regulation, structure-function relationship of TnT and how various ssTnT mutations cause recessive NM, in order to promote in depth studies for further understanding the pathogenesis and pathophysiology of TNNT1 myopathies toward the development of effective treatments.Troponin T (TnT) is the sarcomeric thin filament anchoring subunit of the troponin complex in striated muscles.

The lay population often refers to a scar as an unsightly healed wound. Conversely, surgeons tend to think of surgical scars as an expected outcome of a violation of the dermis. Before initiating treatment, the physician must take the time to understand and diagnose each element. The extent of scar must be considered along with the patient\u2019s intent in getting treatment.2,3This is a prospective study of 50 cases of scar revision performed in our department from 2011- 2014. Mature scars more than 2mm in diameter broad were included in the study. Patients were analysed in terms of patient satisfaction with the post-operative outcome. Patients were followed up for a minimum period of 6 months. Exclusion criteria were (i) pregnant patients, (ii) paediatric patients and (iii) patients with a follow up period of <6 months. Patients were analysed regarding their satisfaction with their post-operative outcome in the form of scar related parameters and psychological parameters. Post-operative patient satisfaction was assessed using pre and post procedure Vancouver Scar Scale scores.The largest number of cases were seen in the age group 16-30 years (78%), of which 21 patients (53.8%) were satisfied with the outcome of their corrective procedure. The preponderance in this age group could be due to the fact that young adults are highly conscious regarding their appearance . Among 2The incidence of post-operative satisfaction was slightly higher among 25 unmarried enrolled patients (60%) compared to 25 studied married patients (52%). No significant difference in post-operative satisfaction could be found in patients with decreased (n=10) or unchanged scar visibility (n=10) following operative procedure. Scars which were converted to lie parallel to Relaxed Skin Tension Lines (RSTL) were seen to have the maximum satisfaction with post-operative results (83%) compared to other patients (72%). However the small number of patients in the category (5 and 8 patients) precludes any statistically significant difference to be obtained. Eighteen patients noticed gain of function of the affected part following scar revision (n=38).All patients with gain of function in the affected part showed satisfaction with their post-operative outcome. The highest incidence of post-operative satisfaction correlates with anxiety relief following correctional procedure (84% of 13 enrolled patients). The highest post-operative satisfaction was seen to correlate with alleviation of depression following correctional procedures (89% of 19 studied patients). No significant difference was seen in post-operative satisfaction rates in patients with either increased or high self-esteem following surgical procedure. However patients with low self-esteem demonstrated lower satisfaction rates compared to their counterparts (40% vs. 56% and 60%). The highest percentage of post-operative satisfaction was seen in patients with improved social acceptance following correctional procedure (73%) when compared to others (50% and 30%). Patients with change of 4 or more between pre and post operative Vancouver Scar Scale scores were satisfied with the outcome of the revisional procedures while those with scores less than 4 were either dissatisfied or neither satisfied nor dissatisfied with the outcome. Post-operative satisfaction in an individual is multifactorial. Females appear to be marginally more satisfied as compared to males with their post operative outcomes. Patients who underwent correctional procedures for cheek scars showed maximum satisfaction post operatively probably because the cheek is an exposed area and defects if an are promptly visible. Even a small improvement in a scar in such a cosmetically important area can bring great satisfaction to the patient.4,5 Following scar revisional procedures, marked reduction in anxiety and depression as compared to pre-operative status was noticed. Also, patients with low self esteem tended to be unsatisfied with their post operative outcome. Increased social acceptance, either real or apparent, could be a major factor leading to this conclusion. Patients in whom scars came to lie parallel to or within RSTL\u2019s post operatively, as compared to pre-operative status in which they did not, showed the maximum level of satisfaction with their corrective procedures.The authors declare no conflict of interest."} +{"text": "Coxiella burnetii infection(s).

This review highlights molecular signatures of UPRER and its key molecular alliance that are affected in aging leading to the development of intriguing neuropathologies in AD. We present a summary of recent studies reporting usage of small molecules as inhibitors or activators of UPRER sensors/effectors in AD that showcase avenues for therapeutic interventions.Alzheimer\u2019s disease (AD), a neurodegenerative disorder, is most common cause of dementia witnessed among aged people. The pathophysiology of AD develops as a consequence of neurofibrillary tangle formation which consists of hyperphosphorylated microtubule associated tau protein and senile plaques of amyloid-\u03b2 (A\u03b2) peptide in specific brain regions that result in synaptic loss and neuronal death. The feeble buffering capacity of endoplasmic reticulum (ER) proteostasis in AD is evident through alteration in unfolded protein response (UPR), where UPR markers express invariably in AD patient\u2019s brain samples. Aging weakens UPR Alzheimer\u2019s disease (AD), the most common form of dementia faced by more than 40 million people worldwide, significantly affect morbidity and mortality in aged people imposed on the neuronal cell due to misfolded protein aggregates. Also, we have discussed various therapeutic interventions targeting the molecules involved in UPR pathways aiming at averting the neuropathologies of AD.The expression pattern of neurodegenerative pathologies shows distinct molecular signatures, such as misfolded A\u03b2 aggregation and tau protein hyperphosphorylation in the brain microenvironment like nutrient deprivation, changes in redox potential, calcium homeostasis, hypoxia and accumulation of unfolded/misfolded protein triggers the UPRER embodies a complex network comprised of three stress-responsive transmembrane proteins, Protein Kinase RNA like ER kinase (PERK), Inositol Requiring Element 1 (IRE1) and Activating Transcription Factor 6 domain models expressing aggregation-prone mutant tau variants, XBP-1 was identified to be playing a similar protective role ensuing after accumulation of unfolded peptide load is well documented. The pathway focuses on invigorating folding and degradation of misfolded peptides in mitochondrial matrix through the execution of retrograde transcriptional activation , but also showed reduction in beta-amyloid aggregation in worms and transgenic mouse models of AD revealed a deranged glucose metabolism in brain regions. Aging registers diminished brain glucose utilization that surges in AD instates mitigating effect on hexosamine pathway (HBP), due to which O-GlcNAcylation is compromised with hyperphosphorylation on tau protein when fed with the drug metformin showed mitigated levels of GRP78 with ensuing gain in lifespan, additionally the expression of GLUT1 and its association with the beginning of UPRER exerted neuroprotective effect , has been known to inhibit BACE1 translation through dephosphorylation of eIF2\u03b1-P resulted in establishing long-term hippocampus memory (Mart\u00ednez et al., 2+ equilibrium, thereby maintains the proper signaling in brain. The disruption in neuronal physiology is quite evident in age-related AD where ER dysfunctions are prominently expressed in the form of imbalance in proteostasis. Advancements in studies based on AD models have clearly shown how we can intervene the molecular pillars of UPRER and its associated signaling cascades to manage neurodegeneration in age-related AD. The present review is an attempt to revise functional relevance of the studies conducted in the field of management of age-related AD through therapeutic interventions on the UPRER pathway and its associate\u2019s molecules. Studies reinforce that the strategies where intervening the molecules, which are involved in transposing effects of aging on neurodegeneration, will cause reduction in probability of AD pathology. The manifestation of ER proteostasis is a direct indication of healthy nervous system. Progression in AD witnesses glucose hypo-metabolism in brain, reduction in glucose transporters in neurons and endothelial cells of blood brain barrier in direct proportion with the amount of neurofibrillary tangles. Type 2 diabetics with higher insulin resistance are at a greater risk of AD. Recent reports elucidate that managing UPRER can exert neuroprotective effect in AD (Smith and Mallucci, mt can impede plaque formation.

Here we compare our findings with those associated with more common forms HSP including: Spastin, Atlastin-1 and REEP 1 which together account for over half of all cases of autosomal dominant HSP. Furthermore, we discuss recent observations in other HSP models which are directly implicated in mitochondrial function and localization. Overall, we highlight the common features of our rare models of HSP and other models of disease which could indicate shared mechanisms underpinning neurodegeneration in these disorders.Hereditary spastic paraplegias (HSPs) are a group of inherited neurodegenerative conditions characterised by retrograde degeneration of the longest motor neurons in the corticospinal tract, resulting in muscle weakness and spasticity of the lower limbs. To date more than 70 genetic loci have been associated with HSP, however the majority of cases are caused by mutations that encode proteins responsible for generating and maintaining tubular endoplasmic reticulum (ER) structure. These ER-shaping proteins are vital for the long-term survival of axons, however the mechanisms by which mutations in these proteins give rise to HSP remain poorly understood. To begin to address this we have characterized Hereditary spastic paraplegias (HSPs) are a group of inherited neurodegenerative disorders characterised by the retrograde degeneration of the longest motor neurons (MNs) in the corticospinal tract, leading to muscle weakness and spasticity of the lower limbs.Historically HSP was grouped into two classifications: \u2018pure HSP\u2019 exclusively exhibiting lower limb spasticity and \u2018complicated HSP\u2019 in which patients presented with additional symptoms including dementia, seizures and amyotrophy in vivo studies consistently reveal that loss of ER-shaping proteins causes profound disruption to the organisation of the ER. Expression of an SPG3A mutant form of Atlastin-1 was found to alter ER-morphology in HeLa cells from a reticular to a more tubular organisationDrosophila nervous system results in visible fragmentation of the ERER-shaping proteins comprise intramembrane hairpin-loop domains by which they localise to and insert into the ER membrane. Spastin, Atlastin-1 and REEP1 are hairpin-loop domain containing ER-shaping proteins which account for ~50% of all autosomal dominant cases of HSP (AD-HSP). Spastin gene mutations cause spastic paraplegia 4 (SPG4) subtype, which represent about 40% of AD-HSPin vivo we have recently reported on models of HSP which we have generated and characterised in the fruit fly, Drosophila melanogasterDrosophila orthologs of RTN2 and ARL6IP1 (Rtnl1 and Arl6IP1 respectively). Gene knockdown models were selected as they likely reflect the loss-of-function genetic variants expressed in SPG12 and SPG61 patients. Mutations in RTN2 include a complete gene deletion and a frameshift mutation predicted to produce a highly truncated protein, suggesting that SPG12 acts via a haploinsufficiency mechanismTo begin to understand the role of ER-shaping proteins in MNs Drosophila MNs. Specifically, mitochondria appear increasingly elongated within axon bundles and mitochondrial load within neuromuscular junction synaptic boutons is significantly reduced in loss of Arl6IP1 and loss of Rtnl1 Drosophila . Importantly, these MAMs mediate mitochondrial fission in which the ER functions to mark mitochondrial constriction sites prior to the recruitment of mitochondrial fission factors such as dynamin related protein 1 (Drp1)s of HSP . In contWhile our Rtnl1 and Arl6IP1 models of HSP represent very rare forms of disease, family which act as microtubule motor proteins involved in the transport of membranous organelles. Mutations in KIF5A cause Charcot-Marie Tooth Disease Type 2 (CMT2) and SPG10Together these data suggest that disruption to the neuronal mitochondrial network, either directly via mitochondrial mutations or indirectly via disrupted tubular ER, underpins much of the axonal degeneration associated with HSP. Altered mitochondrial distribution could disrupt the bioenergetics of different cellular compartments, given the peculiar morphology of neurons with long axons and the requirement for energy at axonal terminals this may cause failure of normal neuronal function. This work illustrates how models of very rare forms of disease may provide novel insights into the molecular mechanisms underpinning HSP more generally and suggest novel targets for therapeutic investigation for these currently untreatable neurodegenerative disorders."} +{"text": "In 2016, CDC saw an increase in cases of acute flaccid myelitis (AFM); 144 persons in 37 states and the District of Columbia were confirmed to have AFM.

One available specimen and three additional specimens, collected 28, 47, and 63 days after onset of focal limb weakness, were sent to CDC for four enterovirus/parechovirus RT-PCR assays. A stool specimen, collected at day 28 from the patient who did not have an NP swab available, was positive for coxsackievirus A10.This cluster of AFM at one children\u2019s acute care hospital is the largest cluster identified to date in Arizona and is part of a nationally identified increase in AFM cases. Although no statewide surveillance system specific to AFM is available, this cluster was detected by physician reporting, highlighting the need for physicians to remain vigilant for this emerging disease and to report cases that fit the AFM case definition to their local health department. Metagenomic analyses identified EV-D68 in NP swabs from the three patients for whom specimens were available, along with a specimen from a patient who did not meet the AFM case definition; therefore, no single etiology or risk factor was associated with only confirmed cases. Patient and family history of asthma was the most common comorbidity reported among confirmed AFM cases and should be considered in future case investigations. Expanded analysis of infectious, postinfectious, and noninfectious etiologies might provide further insight into the mechanism of AFM."} +{"text": "Epidemiology of drug resistant HIV has focused on trends and less attention has been given to identification of factors, especially behaviors including substance use, in acquisition of drug-resistant HIV. From 2009 to 2012 The Metromates Study enrolled and followed for one year men who have sex with men (MSM) seeking testing for HIV in a community clinic in Los Angeles assessing those testing positive for acute and recent HIV infection. Behavioral data were collected via Computer-Assisted Self-Interview from 125 classified as newly HIV infected and 91 as chronically infected (newly HIV-diagnosed); specimens were available and viable for resistance testing for 154 of the 216 HIV positives with new diagnoses. In this community clinic we found prevalence of resistance among MSM with new HIV-diagnosis was 19.5% (n = 30/154) with no difference by recency of HIV infection. Sexual partnership characteristics were associated with resistance; those who reported transgendered sex partners had a higher prevalence of resistance as compared to those who did not report transgendered sex partners , while those who reported having a main partner had a lower prevalence of drug resistance . In multivariable analyses adjusting for HIV recency and antiviral use, reporting a main partner decreased odds , reporting a transgendered partnered increased odds ; and being African American increased odds of drug resistance . This suggests African American MSM and TG individuals in Los Angeles represent pockets of exceptional risk that will require special approaches to prevention and care to enhance their own health and reduce their likelihood to support transmission of drug resistance in the US. Among those with a new diagnosis of HIV infection, some are infected by a strain of HIV-1 resistant to one or more drugs, known as primary or transmitted drug resistance (TDR) but evidBetween 2009\u20132012 321 MSM enrolled in the NIDA funded Metromates Cohort Study conducted at The Los Angeles LGBT Center, a community-based organization providing sexual health services, social services and HIV care in Los Angeles. Men at least 18 years of age reporting sex with a man in the past 12 months who sought HIV testing at the LGBT Center were offered an opportunity to undergo a consent process including a written consent with a full description of the study with choices about if and how to participate in specimen donation, and then were provided a copy of their written consent form . Those who tested HIV-positive provided a specimen for testing of recency of infection using the Vironostika detuned assay (BioSystems Laboratory in San Francisco) a validated assay for use of detection of early HIV infection, 14; negA Computer-Assisted Self-Interview (CASI) assessed sexual partner type ; types of sexual activity ; substance use .

Initiation of care was not an exclusion criteria for this analysis.

Samples were classified as \u201cresistant\u201d if results indicated reduced sensitivity to at least one class of ARVs.HIV genotyping was performed using stored plasma samples collected at study enrollment. The testing of those assessed as acutely infected (n = 104) was conducted at the HIV Genotyping Laboratory at Johns Hopkins University (JHU) and the other new diagnoses at University of California Los Angeles (UCLA) School of Medicine (n = 69). Testing at JHU was conducted using the ViroSeq HIV Genotyping System v2.8 . This system provides HIV sequences for the region encoding HIV protease (amino acids 1\u201399) and HIV reverse transcriptase (amino acids 1\u2013335). Testing at UCLA was done using the UltraSens Viral Isolation kit (Qiagen) according to the manufacturer\u2019s protocol. The Reverse Transcriptase (RT) and Protease (PRO) genes were amplified and sequenced according to the previously published protocol of Snoeck et al. using SuperScript III RT (Invitrogen) for RT and KOD high fidelity polymerase (Novagen) for PCR. PCR products were directly sequenced using the BigDye v3.1 Kit (Applied Biosystems) according to the manufacturer\u2019s protocol using the primers described in Snoeck et al. SequencDifferences in ARV drug resistance to at least one class of HIV drugs by demographics and behaviors were evaluated using t-tests, Wilcoxon rank sum, chi-square methods, Fisher\u2019s exact tests and multivariable logistic regression analysis. Behaviors included in the analyses were selected based on findings from the research team\u2019s previous work with this population and this topic, 17 as wAmong the 154 recently HIV-diagnosed MSM with testable plasma the mean age was 30 years, nearly half identified as Hispanic (48%), followed by white (29%) and African American (17%); 58% were identified as having an acute/recent HIV-infection. The median number of sexual partners in the past 12-months was eight [interquartile range (IQR) 4\u201320], with a median of two anonymous partners and one one-time partner. More than half the participants reported substance use in the past 3 months, including marijuana (41%), methamphetamine (20%), cocaine (15%), and opioids (3%). Eleven (7%) reported sex with both men and women; and 30 (19.5%) reported a transgender partner in the last 12 months; 30 (19.5%) reported transactional sex in the past 3 months. Between screening and enrollment 30 men (19%) had initiated ARV therapy. Among these HIV positive men more methamphetamine use was reported among newly infected than chronically infected .Drug resistance to at least one class of ARVs was identified in 30 (19.5%) of the 154 participants. Most of the resistance was to NNRTIs: 25/30 cases of resistance. The prevalence of ARV resistance did not vary significantly by HIV diagnosis group althoughReporting a main partner decreased odds of drug resistance , reporting a transgendered partnered increased odds ; and being African American increased odds of drug resistance .The prevalence of drug resistance of 19.5% among MSM in Los Angeles with new HIV diagnosis is relatively high compared to other reports even wheThe increased risk of resistance among men who have sex with transgendered (TG) partners is a new finding. TGs represent a marginalized group of individuals among whom adherence to HIV treatment is particularly poor and who Our findings point to the role of the main partner in providing protection against acquiring resistant virus and the increased risk with having casual partners. Clearly the more exposures, the more likely one of these is to someone with a resistant virus. Yet this also suggests that sexual networks are playing an increasingly important role in the transmission of resistance. It points to the need to counsel men without main partners that when they have unprotected sex with casual partners whose HIV status or use of therapy is unknown they may be at higher risk of acquiring resistant virus and that this has the potential to affect their therapeutic options.Our finding that African American MSM were more likely than other MSM in Los Angeles to acquire resistance raises continuing concerns about the epidemic among African American MSM. These men are most likely to acquire HIV in general in the US\u2013with African Americans representing half of all new infections in 2009 and AfriGiven the challenges of enrolling individuals into studies at the time of their HIV diagnosis and identifying those with acute or recent infection in any community, the sample size for this study was relatively small. This limited the power to more sensitively detect factors associated with resistance that were low prevalence. Although the study used computer-assisted interviewing and emphasized the conduct of the study in the most sensitive way for individuals with new HIV diagnosis, behavioral reports are always prone to mis-reporting and that could result in misclassification of participants in the analysis. Finally, the study and was initiated and tools developed in 2008 and earlier, when awareness of and well-developed tools for studying transgender individuals were not yet evolved fully limiting our ability to better study how them.Our findings support the rationale for examining behavioral characteristics of resistance because we could not confirm findings from earlier studies that identified strong use, notably methamphetamine use, as a driver of multi-resistant HIV suggestiThese findings indicate trends in HIV transmission patterns among MSM in Los Angeles.

We identified a novel BRCA1 mutation in two Jewish-non-Ashkenazi families with ovarian cancer: a thymidine to guanidine alteration at position 3053, resulting in substitution of tyrosine at codon 1017 for a stop codon (Tyr1017Ter). The mutation was first detected by protein truncation test (PTT) and confirmed by sequencing and a modified restriction digest assay. Allelotyping of mutation carriers using intragenic BRCA1 markers revealed that the haplotype was identical in these seemingly unrelated families. No mutation carrier was found among 118 unselected Jewish individuals of Iranian origin. Our findings suggest that this novel mutation should be incorporated into the panel of mutations analysed in high-risk families of the appropriate ethnic background, and that the repertoire of BRCA1 mutations in Jewish high-risk families may be limited, regardless of ethnic origin."} +{"text": "An ascitic form of plasmacytoma (MP-5563) in C3H mice has proved stable on transplantation.

The high dose cytolethal response appears non-specific occurring in all cell lines with every steroid tested. By contrast, the low dose cytolethal response requires an active glucocorticoid and a sensitive HLCL. However, both high and low concentrations of steroid induce virtually identical morphological changes in dying cells and similar changes can be induced in cells killed by deliberate feed exhaustion. Although the morphological features in each case resemble apoptosis, the \"programmed\" physiological form of cell death, the intracellular events leading to cytolysis seem likely to differ. The earliest morphological changes presaging cell death comprise rounding up of cells and condensation of nuclear chromatin. Nuclear changes progress rapidly thereafter and appear to result from detachment of chromatin from the nuclear matrix. The low dose cytolethal response requires the continuous presence of glucocorticoid for periods in excess of 24h, prior to which cell growth appears unaffected. The constancy of this latent interval suggests glucocorticoids may influence some replication control mechanism unrelated initially to macromolecular biosynthesis."} +{"text": "We examined the localization of basic fibroblast growth factor (bFGF) in a series of human breast carcinomas using immunohistochemistry.

Hierarchical cluster analysis was performed to compare chromosome 3 transcriptome patterns of each growth condition. Differentially expressed genes were identified and characterized by two-way comparative analyses of fold-differences in gene expression between monolayer cultures and each of the other growth conditions, and between the maximum and minimum values of expression of all growth conditions for each EOC cell line.An overall high degree of similarity (> 90%) in gene expression was observed when expression values of alternative growth conditions were compared within each EOC cell line group. Two-way comparative analysis of each EOC cell line grown in an alternative condition relative to the monolayer culture showed that overall less than 15% of probe sets exhibited at least a 3-fold difference in expression profile.

As monolayer cultures are often used in molecular genetic assays of cancer derived cell lines, we compared gene expression values of the EOC cell lines grown as monolayer cultures with each of the alternative growth conditions comprised of spheroid cultures (S), nude mouse xenografts at subcutaneous (TSC) or intraperitoneal (TIP) sites, and monolayer cultures of subcutaneous (LSC) and intraperitoneal (LIP) xenografts. We performed two-way comparison analysis based on fold-differences using the expression values which contained at least one high reliability score per probe set for each EOC cell line. Using this criterion, the expression values of 692 (60.3%), 739 64.4%), and 693 (60.4%) probe sets from the total of 1147 chromosome 3 probe sets for OV-90, TOV-21G and TOV-112D, respectively, were evaluated for fold-differences of the expression values exhibited by all alternative growth conditions. Two-way comparative analysis was performed between the maximum and minimum values of expression observed for probe sets for each EOC cell line group. A minimum 3-fold cut-off was used to characterize differences in gene expression. Overall less than 23% of probe sets exhibited greater than 3-fold differences in gene expression in this comparative analysis in any EOC cell line group and both subcutaneous (TSC) and intraperitoneal (TIP) xenografts exhibited the lowest values of expression of this gene xenograft sample and the lowest value was observed with intraperitoneal (TIP) xenograft in gene expression in each EOC cell line group tested irrespective of growth condition.

Overall these results attests to the validity of the EOC cell lines as an in vitro model for studying gene candidates but point out that some genes may be influenced by microenvironment, a factor that should be taken into consideration when investigating the molecular biology of specific genes. As our EOC cell lines are amenable to propagation in alternative growth conditions one could assay and further investigate the magnitude of transcriptional effects for specific candidate genes of interest and their consequences at the protein level to further understand the biological relevance gene expression differences associated with microenvironment.Future experiments are required to determine if the differences observed in the EOC cell lines grown in alternative conditions are biologically relevant or a reflection of experimental design.

Cell lines showing drug resistance following prolonged exposure to a single agent frequently acquire resistance to several functionally unrelated drugs, the phenomenon of multi-drug resistance (MDR). Classical MDR is thought to arise from changes effecting a reduction in intracellular availability of cytotoxic drugs. We describe a flow cytometry (FCM) technique to monitor the MDR phenotype in drug resistant variants of SCLC and non-SCLC cell lines. The technique is based on a multiparametric analysis of the nuclear binding of a model chemotherapeutic agent, the fluorescent dye Hoechst 33342 (Ho342), which is capable of supra-vital staining of DNA in intact, viable cells. A laboratory derived drug resistant SCLC cell line, H69/LX4, showed a significant (30%) reduction in nuclear binding compared to the parental line H69/P. Exposure to verapamil (VPL) rapidly increased (within 2 min) nuclear binding of Ho342, and the new equilibrium of nuclear staining, attained within 20 min, remained lower than the level achieved in the parental cell line, suggesting some ability of H69/LX4 to limit the effect of the drug efflux blocker. A drug resistant large cell carcinoma line showed only a small reduction (10%) in nuclear binding when compared to the parent line, and this difference was not altered by VPL. A drug resistant adenocarcinoma line showed less than 10% difference in nuclear binding compared with the parental line and neither line was significantly affected by VPL treatment. Our findings suggest that different mechanisms of resistance may occur in lung tumours of different tissue types. This technique may be extended to the rapid and direct examination of biopsy specimens of human solid tumours for evidence of multi-drug resistance."} +{"text": "Several cobalt(II), copper(II) and nickel(II) complexes of nicotinoylhydrazine-derived compounds were prepared and characterised by physical, spectral and analytical data.

Prior to the development of prophylactic strategies or treatment protocols a detailed understanding of the mechanisms of radiation induced CNS toxicity is mandatory. Histological analysis of irradiated CNS specimens defines possible target structures prior to a delineation of cellular and molecular mechanisms. Several lesions can be distinguished: Demyelination, proliferative and degenerative glial reactions, endothelial cell loss and capillary occlusion. All changes are likely to result from complex alterations within several functional CNS compartments. Thus, a single mechanism responsible cannot be separated. At least four factors contribute to the development of CNS toxicity: (1) damage to vessel structures; (2) deletion of oligodendrocyte-2 astrocyte progenitors (O-2A) and mature oligodendrocytes; (3) deletion of neural stem cell populations in the hippocampus, cerebellum and cortex; (4) generalized alterations of cytokine expression.

All the foreign bodies were removed through the sclerocorneal tunnel.All the 18 patients were young males, with an average follow-up period of 12 months. In 12 cases the foreign body was intravitreal and in six cases it was intraretinal but extramacular. Thirteen cases had a best corrected visual acuity ranging from 20/20 to 20/60 at their last follow-up. Five cases developed retinal detachment due to proliferative vitreoretinopathy (PVR) changes postoperatively and were subsequently managed by surgery.Primary IOL implantation with combined cataract and vitreo-retinal surgery is a safe option reducing the need for two separate surgeries in selected patients with retained IOFB and traumatic cataract. This combined procedure provides good visual outcome with early rehabilitation in young working patients. Open globe injury with or without intraocular foreign body (IOFB) often has a poor visual outcome owing to possible endophthalmitis and/or vitreo retinopathy with the varied and unsterile wounds associated with it.\u20133 ManageMethods for removal of the traumatic cataract include lensectomy, conventional extra-capsular cataract extraction (ECCE), manual small-incision cataract surgery (SICS) and phacoemulsification. Unlike lensectomy other methods of cataract extraction offer a better visual rehabilitation because of implanted intraocular lens (IOL).\u20138 Most sTo avoid such complications, in this series we performed cataract extraction by manual SICS , removed the foreign body through the same tunnel and implanted a posterior chamber IOL (PCIOL) over the anterior capsular rim. The aim of the study was to evaluate visual outcome following pars plana vitrectomy (PPV) and IOFB removal through the sclerocorneal tunnel combined with simultaneous cataract extraction and sulcus-fixated IOL implantation as a single procedure in penetrating trauma with IOFB and traumatic cataract.Medical records of patients with penetrating eye injury and IOFB attending the retina clinic between June 2004 and December 2005 were reviewed. Out of 28 consecutive patients, 10 patients were excluded from this study because of absence of cataract, presence of associated endophthalmitis, severely injured lens with vitreous in the anterior chamber and evidence of zonular dehiscence.Eighteen patients with clinically significant lens opacification and IOFB with or without concomitant vitreoretinal pathology were included in the study. Primary repair was done in all cases except three, where the wound was self-sealed and they were taken up for vitreoretinal procedure directly. All patients underwent a complete general ophthalmologic examination prior to the surgical procedure. Preoperative visual acuity, site of entry of foreign body (FB), capsular and zonular integrity was assessed. Ultrasound B-Scan and/or X-ray of orbit were performed in all patients to locate and evaluate the IOFB. Keratometry and biometry of the injured eyes were done. If keratometry and biometry was not possible on the injured eye, fellow eye measurements were used. In all cases manual SICS was performed before the vitreoretinal procedure. A 6 mm frown-shaped sclerocorneal tunnel was made, followed by continuous curvilinear capsulorrexis and hydrodelineation. The lens nucleus was prolapsed into the anterior chamber and removed through the tunnel by sandwich method.\u201311 Rest 12Sclerotomies and conjunctiva were closed with 6-0 vicryl and 2 mg dexamethasone and 2 mg gentamicin sulphate were injected subconjunctivally. Postoperatively all patients received topical antibiotics and steroid for four weeks with gradual tapering. Oral ciprofloxacin 500 mg twice daily along with nonsteroidal anti-inflammatory agents was given in all cases with addition of systemic steroids when necessary. In each case recording of best corrected visual acuity (BCVA), intraocular pressure measurement, slit-lamp biomicroscopy and indirect ophthalmoscopy was done postoperatively. Cause of decreased vision was assessed considering site of entry of FB, site of lodgment of FB and postoperative complications like RD in each case.All our patients were young males with mean age of 24.5 years. The minimum follow-up period was four months, the maximum being 18 months with median follow-up time of 12 months. In 12 out of 18 cases the FB was intravitreal and in six cases it was intraretinal but extramacular. Thirteen out of 18 cases had BCVA between 20/20 and 20/60. Anatomical success was achieved in 13 out of 18 cases with 11 patients having visual acuity 20/30 or better with first vitreoretinal procedure. With the second vitreoretinal procedure four out of five patients had anatomical success .et al.[We reviewed the visual outcome and complications in 18 patients with penetrating intraocular injury, significant cataract and retained IOFB, who underwent manual SICS, PPV, removal of IOFB and implantation of PCIOL.

We found no significant correlation in \u2018duration between injury and vitreoretinal procedure\u2019 which is well supported by other studies.14\u201319 ButSclerocorneal tunnel and sclerotomy have their advantages and disadvantages as a route for removal of IOFB. Enlargement of sclerotomy carries risk of hypotony, vitreous hemorrhage, peripheral vitreous incarceration into the wound intraoperatively, and RD postoperatively. Removal of the FB through sclerocorneal tunnel may damage or sacrifice the integrity of the posterior lens capsule and anterior capsular rim, but large FBs are easily removed through the sclerocorneal tunnel.\u201319et al.[et al.[et al.[et al.[Except few isolated case reports with large IOFBs, so far there is no data on removal of cataract and FB through the same route. In our experience, IOFB can be safely removed through the sclerocorneal tunnel and IOL can easily be implanted into the cilliary sulcus. In our study, the final BCVA was 20/30 or better in seven out of 18 cases, between 20/40 and 20/60 in six cases and counting finger (CF) at 1 meter (1 m) or less in five cases. This was very well comparable with similar studies.\u201381314 Az813et al. reportedl.[et al. reportedLate onset of RD in our series was seen in five out of 18 cases. The incidence of RD in the intraretinal FB group in this series was seen in five out of six cases.

HDACi treatment also partially relieved the normal down-regulation of early transcription by T-antigen seen later in infection. The increased recruitment of transcribing minichromosomes at late times was correlated to a corresponding reduction in SV40 replication and the percentage of minichromosomes capable of replication.These results suggest that histone deacetylation plays a critical role in the regulation of many aspects of an SV40 lytic infection.

PCPA (2 g 8 hourly for 2 or 3 days prior to cisplatin) reduced the spontaneous urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA), inhibited the increase in urinary 5-HIAA induced by cisplatin and markedly attenuated the acute period of nausea and vomiting associated with the cytotoxic drug. These results indicate that gastrointestinal serotonin mediates cisplatin-induced emesis and that the amount of serotonin released by cisplatin is a major factor in determining the severity of the acute period of emesis experienced by the patient."} +{"text": "Between January 1981 and December 1985, 122 patients with non-seminomatous germ cell tumours (NSGT) were seen at a regional referral centre. Of these, a total of 98 patients received chemotherapy for metastatic disease. Treatment was given within collaborative EORTC Urology group studies, all of which involved cis-platin-containing schedules. Ninety patients had tumours of testicular origin, and their 2 year actuarial survival rate is 91%; 8 had tumours of extragonadal origin and their 2 year actuarial survival is 25%. Patients with testicular tumours were subdivided by volume of metastatic disease using the recommendations of the Testicular Cancer Subgroup of the MRC Urological Cancer Working Party and survival was significantly worse in the group with very large volume metastatic disease compared with the groups with large volume metastases and small volume metastases . There were 31 patients with Stage I disease at presentation; of these 6 were treated by prophylactic abdominal radiotherapy and 25 were managed by a policy of surveillance only. Seven of these Stage I patients (23%) relapsed with metastatic disease (median 8 months); all have been successfully treated with chemotherapy. These data confirm that the majority of patients now presenting with metastatic NSGCT are curable with chemotherapy, but that a small proportion with very large volume metastases or extragonadal tumours require alternative chemotherapy schedules."} +{"text": "Cytological studies in the light microscope showed that thioacetamide (TAA) depressed the mitotic index in cultures of skin fibroblasts at the lowest concentrations used (100 \u03bcg/ml). At high concentration (1 mg/ml), TAA tended to cause aberration in nuclear morphology. Ethylenethiourea (ETU) had no effect on either mitotic index or nuclear morphology at 1 mg/ml. Fibroblast cultures treated with 1 mg/ml TAA and cultures grown in the presence of 2 mg/ml ETU were studied by electron microscopy. In some TAA-treated cells there was unfolding of the nuclear membrane and enlargement and granulation of the nucleolus, but these effects were not correlated. In all cells, TAA caused severe and characteristic damage to the majority of mitochondria, whether or not there were nuclear aberrations. The organelle showed extensive swelling of the cristae of the inner membrane and an increase in matrix density. Ultrastructure of other cell components appeared to be unaffected by this treatment. In ETU-treated cells some less severe swelling of inner mitochondrial membranes was seen and only in a minority of cells, whilst all other cell structures appeared normal. Similar membrane swelling and increase in matrix density was seen in isolated rat liver mitochondria after incubation with TAA, indicating a direct antimitochondrial effect of the carcinogen.When yeast cells were treated with TAA and ETU, primary antimitochondrial activity of these compounds was apparent from (1) inhibition of growth in non-fermentable medium, (2) selective blockage of mitochondrial protein synthesis and (3) induction of mitochondrial mutations. TAA was much more effective than ETU in all these respects."} +{"text": "Sir,In a recent letter criticising one of several IARC Interphone studies investigating possible associations between mobile phone use and brain tumour risk, Editors NoteThe Editor-in-Chief of British Journal of Cancer now considers the correspondence published in Volume 94 Issue 9 and above closed."} +{"text": "Purpose: Soft tissue sarcomas (STS) account for less than 1% of all malignancies and constitute a heterogeneous tumor entity in which malignant fibrous histiocytomas (MFH) represent one-third and are characterized by a lack of type-specific differentiation. A defective mismatch repair (MMR) system cause the familial cancer syndrome hereditary non-polyposis colorectal cancer (HNPCC), and since occasional MFH have been described in HNPCC patients we assessed the contribution of defective MMR to the development of MFH.Methods: MMR status was characterized in a series of 209 histopathologically reviewed MFH. Tissue microarray sections from the tumors were immunohistochemically stained for the MMR proteins MLH1, MSH2 and MSH6, and cases with aberrant staining were further characterized for microsatellite instability.Results and Discussion: Two of the 209 STS\u2013a storiform-pleomorphic MFH and a myxofibrosarcoma\u2013showed concomitant loss of MSH2 and MSH6, but retained staining for MLH1 on both cases. The myxoid tumor also had a microsatellite unstable phenotype. These findings, together with previous observations of defective MMR in pleomorphic STS, indicate that these tumors may be part of the HNPCC-associated tumor spectrum and demonstrate that MMR defects occur in a small subset of STS."} +{"text": "Girls who engage in strenuous physical activity are often amenorrheic and have recently been reported to be at a reduced risk of breast cancer. To determine whether moderate amounts of exercise affect menstrual cycle patterns and ovulatory frequency in young postmenarcheal girls, the menstrual cycles and physical activity patterns of 168 high school girls were monitored for a 6 month period. Anovulatory cycles were associated with later age at menarche, fewer elapsed years since menarche and greater levels of energy expended per week in physical activity. After adjusting for age at menarche and years since menarche, there was a significant dose-related trend in the risk of anovular menstrual cycles associated with increasing levels of physical activity (1-sided P = 0.03). Major determinants of average cycle length were weekly average energy expenditure , age at menarche (an increase of 0.7 days per year of age) and race (Asians having cycles about 1.9 days longer than Caucasians). Because a major determinant of breast cancer risk may be the cumulative number of ovulatory cycles, these data suggest that regular participation in moderate physical activity, by reducing the frequency of ovulatory cycles in adolescence, may provide an opportunity for the primary prevention of breast cancer."} +{"text": "The structure of circulating chromogranin A (CgA) of phaeochromocytoma patients was characterised and compared with that of CgA extracted from tumours. Size exclusion chromatography experiments provided evidence that CgA is present in the blood of different patients, as well as in tumour extracts, as multiple forms having different hydrodynamic sizes of 600 kDa (CgA-I), 100 kDa (CgA-II) and 55 kDA (CgA-III). The amount of each CgA form as a proportion of the total antigenic material was different in different patients. Western blot analysis of chromatographic fractions indicated that these forms are made up by polypeptides of similar molecular weight (about 60-70 kDa). All CgA forms express the epitopes recognised by two monoclonal antibodies (A11 and B4E11), directed against residues 68-70 and 81-90 of human CgA. However, their relative immunoreactivity was markedly different. No evidence for the presence of multimeric complexes in the CgA-I fraction was obtained by various immunological and biochemical methods. These results suggest that circulating CgA in phaeochromocytoma patients consists of at least three forms that appear to be made up by polypeptides with similar molecular weight and different hydrodynamic properties and immunoreactivity. We hypothesise that different conformations and shapes contribute to the heterogeneity of circulating CgA."} +{"text": "After the 1999 West Nile (WN) encephalitis outbreak in New York, 2,300 overwintering adult mosquitoes were tested for WN virus by cell culture and reverse transcriptase-polymerase chain reaction.

It has been attributed to variations in incidence of the predominant histological type, hepatocellular carcinoma (HCC). The incidence of PLC types other than HCC such as cholangiocellular carcinoma (CCC) is far less known, especially in low-incidence areas. The aetiology of HCC and other PLC types is obscure, with the exception of the association between HCC and cirrhosis as well as chronic viral hepatitis. The present retrospective incidence and aetiology study concerns a well-defined population from a period with a high autopsy frequency. Preserved biopsy specimens were re-evaluated histopathologically and patient records were studied. Among 590 histologically verified cases of PLC, HCC constituted 90%, CCC 8% and a mixed form of these types 1%. At the end of the study period the annual age-standardised incidence rate of HCC was 3.6 cases per 100,000 inhabitants. Other PLC types were hepatoblastoma (n = 3), fibrolamellar carcinoma (n = 2), angiosarcoma (n = 1) and infantile haemangioendothelioma (n = 1), each constituting less than 1% of the PLC cases. Comparing HCC with CCC we found that cirrhosis (70%) and alcoholism (21%) was significantly more frequent in HCC, and cholelithiasis was significantly more common (60%) in patients with CCC. In the majority of the PLC cases with liver cirrhosis this disorder was unknown before diagnosis of the tumour."} +{"text": "Malignant pericarditis, when associated with massive pericardial effusion, presents a critical condition in lung cancer patients. Because this condition often arises in terminally ill patients, intensive therapy such as multi-drug combination chemotherapy is rarely appropriate. This study evaluated the clinical relevance of intrapericardial administration of carboplatin for controlling malignant pericardial effusions associated with non-small-cell lung carcinoma (NSCLC). The method used for 10 eligible patients consisted of draining the pericardial effusion and infusing 300 mg/body of carboplatin in 50 ml of saline through an in-place catheter into the pericardial space and clamping the catheter for 40 min. Nine of the 10 patients showed satisfactory results, and 8 experienced complete regression of the effusion. No major or minor adverse effects were observed. Pharmacokinetics analysis revealed that the concentration of free platinum in the pericardial fluid was very high while that of total platinum in the circulating plasma was very low, assuring the usefulness of the intrapericardial instillation of carboplatin in terminally ill patients for controlling malignant pericardial effusion when the systemic delivery of cytotoxic agents is inappropriate. \u00a9 2000 Cancer Research Campaign"} +{"text": "The present study evaluated serial serum measurements of tissue polypeptide-specific antigen (TPS) in comparison with prostate-specific antigen (PSA) for assessment of tumour progression in patients with advanced prostate cancer receiving intermittent androgen suppression therapy (IAS). Twenty-three men were recruited into an IAS trial consisting of an initial 8 months of androgen suppression, followed by cycles of treatment cessation and resumption of therapy upon increases of PSA > 20 ng ml(-1) to prolong the hormone responsiveness of the tumour cells. Periods of androgen suppression resulted in reversible reduction in serum testosterone (< 1.8 nmol I(-1)) and PSA (< 4 ng ml(-1)) and decreases in tumour volume (mean reduction for first cycle 24 +/- 10%), indicating partial growth arrest and apoptotic regression of the tumours. In contrast to PSA values, non-specifically elevated TPS values were found in 8 of 23 patients. In 15 of 23 patients, TPS fell during periods of apoptotic tumour regression and increased simultaneously with testosterone and preceded the increases in PSA by 2 months during the period of treatment cessation. Although TPS represents a highly sensitive marker of tumour proliferation in this IAS clinical model of controlled tumour regression and regrowth, its low specificity compared with PSA limits its usefulness to monitoring of prostate cancer patients with proven absence of non-specific elevations of this marker."} +{"text": "The presence of tumour cells in the blood circulation may predict disease recurrence and metastasis. We have evaluated the specificity and sensitivity of detecting hepatoma cells in blood using nested polymerase chain reaction with primers specific for the alphafetoprotein (AFP) gene. The nested polymerase chain reaction amplified a 270-base pair AFP DNA fragment from cDNA of Hep 3B hepatoma cells. In a reconstitution experiment, AFP mRNA was detected from peripheral mononuclear cells isolated from 10 ml of blood containing as few as ten Hep 3B cells. Peripheral mononuclear cells from the blood of 20 hepatoma patients were analysed, and 19 patients showed positive AFP mRNA expression. Seven of 13 samples from hepatitis patients also showed positive AFP mRNA expression. All five paired samples of peripheral blood or umbilical cord blood from pregnant mothers and their babies, respectively, showed positive AFP expression. None of 22 control samples was positive. The presence of AFP mRNA in the blood of hepatitis or hepatoma patients suggests the presence of circulating hepatoma cells or hepatocytes in the circulation. The high incidence of AFP mRNA in the blood of hepatoma patients supports the notion of early haematogenous spreading of the disease."} +{"text": "The cytoreductive effects of anti-transferrin receptor (anti-TfnR) immunotoxins (ITs) and of ricin toxin against tumour micromasses have been evaluated in a multicellular tumour spheroid (MTS) model. More than 600 (656) MTSs obtained with human breast carcinoma (MCF7) or rat glioblastoma (9L) cell lines were treated individually with ITs or toxin and the effects induced by the treatment were measured for each MTS as volume variation vs time by applying the Gompertz growth model. Two dose-dependent patterns of MTS growth were observed in MTSs of both cell lines in response to IT or toxin treatment: (1) complete inhibition of MTS growth ('sterilisation'); and (2) partial/complete inhibition ('heterogeneous response'). Within the range of IT or toxin concentrations resulting in partial inhibition of MTS growth, the sensitivity of treated MTSs was extremely heterogeneous (the cytoreductive effects varying between 0.1 and 4 logs of cells killed for a given IT or toxin concentration). Analysis of the post-treatment regrowth kinetics indicated that treated non-sterilised and control MTSs reached the same final limiting volumes. However, the doubling time estimated for the surviving cells of treated MCF7 and 9L MTSs ranged between 15 and 50 h, indicating that each MTS had individual growing potential. In conclusion, our results indicate that at substerilising IT concentrations individual heterogenicity of MTSs may greatly influence the cytoreductive potential of ITs. An implication of our study is that the efficacy of an IT treatment in eradicating disseminated micrometastases may not be predictable a priori. The MTS model that we describe in this paper may help in dissecting out factors limiting the effect of ITs in three-dimensional tumours."} +{"text": "Twenty-seven patients with Hodgkin's (n = 19) and non-Hodgkin's (n = 8) lymphomas underwent cytological and colposcopic screening of the uterine cervix.

Lymphoma patients were compared with 79 controls with normal cervical cytology and no known haematological abnormality. Colposcopically directed punch biopsies were taken from the cervical transformation zone of all controls. Significantly more lymphoma patients (19%) than controls (3%) had CIN II or III (P less than 0.01) and cervical human papillomavirus infection, as judged by the presence of koilocytes . All six lymphoma patients with CIN had Hodgkin's disease (HD), and five had received combination chemotherapy. Half of the cases of CIN in lymphoma patients and all the cases of CIN in control patients were not detected by cervical cytology.

In addition, 4 myeloma cell lines all expressed high levels of telomerase activity. The expression of telomerase reverse transcriptase (hTERT) and telomerase RNA template (hTER) was positively associated with the levels of telomerase activity in MM/PCL. Tankyrase expression was upregulated, concomitant with the induction of hTERT and activation of telomerase in MM/PCL.

Another important factor was non-willingness to come thrice weekly for the drug administration (9%) during the intensive phase and most of the cases were from low socioeconomic strata and to them earning was more important than spending time at DOTS center for treatment. This factor becomes still more important when the symptoms of the disease are alleviated by initial treatment.The average contact of tuberculosis patients was as high up to seven to eight in our study and as nucleus of Indian household is very compact and transmission of disease is easier, presence of a resistant case in such a situation increases chances of primary drug resistance.The above study was prompted by large number of DOTS failure coming to our department and it throws some light on some of the problems of DOTS CAT II. The important causes of CAT II failure were previous CAT I failure, initial wrong categorization in CAT I, initial heavy bacillary load and non-adherence to treatment."} +{"text": "Mice were injected with tritiated misonidazole (750 mg/kg-1), killed after 24h and the excised tissues prepared for autoradiography (ARG) to identify sites of accumulation.

In 15 patients the disease was active; in the others it was in remission. Patients with active disease had raised serum AFP levels which correlated well with disease activity; no patient without evidence of active disease had raised serum AFP levels. None of the patients with active disease was found to have raised serum CEA levels.

Using a radioimmunoassay (RIA) with a sensitivity down to 2kul-1 the majority (57%) of 28 patients with non-AFP producing germ cell tumours had measurable immunologically-reactive AFP in their serum while on treatment. Follow-up for 11-43 months (mean 27) without evidence of tumour activity indicated that this immunologically-reactive AFP was unlikely to be produced by tumour. In patients where the initial serum AFP was raised prior to chemotherapy the AFP concentration did not fall to the normal range at the end of the treatment in 16 (32%) of 41 patients. Follow-up of these patients for 9-48 months (mean 27) has resulted in 5 (12%) relapses in this group. Serum AFP greater than 20kul-1 three months after stopping chemotherapy was a good indicator of residual active tumour and 4 (57%) of 7 patients in this group relapsed. The production of detectable serum AFP is probably related to the type of chemotherapy used and only 7 (14%) of 51 patients treated for gestational choriocarcinoma had detectable AFP concentrations while on cytotoxic chemotherapy. The problem of interpretation of serum AFP concentration in patients with malignant germ cell tumour stresses the need to determine whether there are differences between AFP produced by germ cell tumours and that produced at other sites as a basis for a sensitive assay system able to discriminate between them."} +{"text": "Human dialysable Transfer Factor (TFd) extracted from lymphocytes of patients with transitional cell carcinoma of bladder (TCCB) was replicated in culture by lymphoblastoid cell lines.

Supernatants were collected at 24h intervals and tested in a microcytotoxicity assay for blocking and ADCC activities. Factors that inhibited tumour destruction by specifically sensitized lymphocytes at the level of both the tumour cells and effector cells were demonstrable in culture supernatants of NL pretreated with TLRNA (50 or 100 microgram/4 X 10(6) cells) but not ILRNA. However, treatment of NL with either RNA resulted in the production factors that mediated tumour-specific ADCC. Cytotoxicity testing and absorption studies of the tumour cell and a control cell (LM) indicated that factors mediating ADCC and blocking at the target-cell level were specific for the tumour. Suppressor activity at the effector-cell level was not absorbed by tumour cells and represents a separate and distinct mechanism of immunosuppression.

In all cancerous specimens obtained from 30 patients, FISH identified cells with clonal chromosomal abnormalities, with aneuploidy rates ranging from 6% to 92% (median 59%). There was a gain of centromeric signals for chromosome 11, most likely corresponding to hyperploidy; aberrations of chromosome 17 in specimens from 26 patients (87%) were hyperploid as well; however, four cases (13%) showed loss of chromosome 17 centromeres. All specimens contained heterogeneous aneuploid cell populations with excessive gain of signals in some cases. The pattern of aneuploidy did not appear to correlate with tumour grade/stage and was comparable in primary tumours and corresponding metastatic axillary lymph nodes, indicative of genetic instability early in tumour development.

Several regions were scraped out and analysed when an adenoma contained areas with different grades of dysplasia. The frequencies of K-ras gene mutation in mild dysplasia, moderate dysplasia and focal carcinoma were 19% (7/36), 51% (25/49) and 39% (14/36) respectively. The K-ras gene status was heterogeneous in 4 of the 11 benign adenomas from which multiple samples were obtained, and mutations were always found in the regions with more advanced dysplasia in these adenomas. Thirteen of the 36 adenomas with focal carcinoma showed heterogeneity of mutations between the adenoma region and the focal carcinoma. Seven of which had mutations only in the adenoma region. These findings indicated that the K-ras gene mutations occur during the late stage of adenoma progression and may confer a more advanced morphological phenotype of adenoma, but these mutations are not mainly involved in malignant transformation from adenoma to carcinoma."} +{"text": "Methotrexate (MTX) shows consistent cytotoxicity for melanoma cells in vitro but it is ineffective in clinical use at equivalent concentrations in vivo.

In an in vitro model of high dose MTX therapy followed by leucovorin rescue (HD-MTX-LCR) there was survival of both melanoma and choriocarcinoma cell lines but not of an acute lymphocytic leukaemia cell line. The 70H metabolite of MTX was identified by HPLC in plasma samples of melanoma patients treated by HD-MTX-LCR, in which MTX concentrations approximately 10(-5) M were maintained for 24 h. However, metabolism per se is unlikely to account for the lack of response to MTX clinically. In vitro 70H MTX (10(-7) - 10(-6) M) was two orders of magnitude less cytotoxic for melanoma than MTX (10(-9) - 10(-8) M). The cellular accumulation of [3H]-MTX, using a rapid gradient centrifuge technique for separation of melanoma cells from medium, was reduced in the presence of 70H-MTX.

The cytotoxicity of mitoxantrone, paclitaxel and topotecan was therefore assessed at low pHe and after manipulation of intracellular pH (pHi) in murine EMT6 and in human MGH-U1 cells. The cytotoxic efficacy of all three agents was reduced at pHe 6.5 as compared with pHe 7.4. The ionophore nigericin and inhibitors of membrane-based ion exchange mechanisms that regulate pHi were used to cause intracellular acidification. Combined use of the cytostatic drugs with pHi modifiers reduced their cytotoxicity under both physiological and low-pHe conditions. The uptake into cells of mitoxantrone (a weak base) was inhibited at pHe 6.5 as compared with pHe 7.4, and smaller effects of low pHe to inhibit uptake of topotecan were also observed. DNA analysis of cell cycle distribution revealed that intracellular acidification, as observed during incubation at low pHe and/or using pHi modifiers, resulted in accumulation of cells in G1 phase, where they may be more resistant to these drugs. Reduced uptake of weak bases (mitoxantrone) at low pHe and altered cell cycle kinetics upon acidification are the postulated causes of reduced cytotoxicity of the agents investigated."} +{"text": "Nuclear and cytoplasmic oestrogen receptors (REN and REC) were sought in 5 normal cervices and in 43 specimens of squamous carcinoma of the cervix. All 3 tissues components of the 5 normal cervices contained both REN and REC. Thirty-five (81%) of the tumours contained receptors, but in only 9 (21%) were they found in both subcellular compartments. Twenty-four tumours (56%) had only REC and 2 had only REN. The potential therapeutic significance of these findings is not yet known, but it seems possible that tumours with an intact receptor mechanism might benefit from oestrogen therapy and have a more favourable prognosis."} +{"text": "We evaluated West Nile (WN) virus seroprevalence in healthy horses, dogs, and cats in New York City after an outbreak of human WN virus encephalitis in 1999.

While histologically normal endometrium, cervical epithelium and ovary expressed detectable mRNA of the DCC gene, three of eight (37%) endometrial carcinomas, one of two (50%) cervical carcinomas and 9 of 22 (41%) ovarian malignant tumours had significantly reduced or negligible DCC expression, and another endometrial carcinoma and two other ovarian tumors underexpressed DCC when compared with histologically normal endometrial or ovarian tissues. Impaired DCC mRNA expression was detected more frequently in grade 3 ovarian epithelial tumours than in grade 1 tumours (P = 0.002). Loss of expression of the DCC gene product detected by immunohistochemistry significantly correlated with the loss of mRNA expression in ovarian carcinomas (P = 0.01 by chi-square test) or in both endometrial and ovarian carcinomas combined (P = 0.001). Loss of heterozygosity of the DCC gene was also evaluated by restriction fragment polymorphism analysis of the polymerase chain reaction-amplified DNA fragment. Loss of heterozygosity of the DCC gene was detected in one of seven (14%) informative cases of endometrial carcinomas, 1 of 11 (9%) informative cases of cervical carcinomas and two of six (33%) informative cases of ovarian tumours. These results demonstrate that inactivation of the DCC gene, especially by the loss of expression, plays a significant role in the aetiology of neoplasms of the human reproductive tract."} +{"text": "Signal transduction pathways activated by injury play a central role in coordinating the cellular responses that determine whether a cell survives or dies. GADD153 expression increases markedly in response to some types of cellular injury and the product of this gene causes cell cycle arrest. Using induction of GADD153 as a model, we have investigated the activation of the cellular injury response after treatment with taxol and cisplatin (cDDP). Activation of the GADD153 promoter coupled to the luciferase gene and transfected into human ovarian carcinoma 2008 cells correlated well with the increase in endogenous GADD153 mRNA after treatment with taxol but not after treatment with cDDP. Following treatment with cDDP, the increase in endogenous GADD153 mRNA was 10-fold greater than the increase in GADD153 promoter activity. Likewise, at equitoxic levels of exposure (IC80), cDDP produced a 5-fold greater increase in endogenous GADD153 mRNA than taxol. The tyrosine kinase inhibitor tyrophostin B46 had no significant effect on the ability of taxol to activate the GADD153 promoter, but inhibited activation of the GADD153 promoter by cDDP in a concentration-dependent manner. Tyrphostin B46 synergistically enhanced the cytotoxicity of cisplatin; however, the same exposure had no significant effect on the cytotoxicity of taxol. We conclude that (1) taxol and cDDP activate GADD153 promoter activity through different mechanisms; (2) the signal transduction pathway mediating induction by cDDP involves a tyrosine kinase inhibitable by tyrphostin B46; and (3) that inhibition of this signal transduction pathway by tyrphostin synergistically enhances cDDP toxicity."} +{"text": "In 104 patients with gastric cancer the serum proteins carcinoembryonic antigen (CEA), C-reactive protein (CRP), alpha 1-acid glycoprotein (AGP) (orosomucoid) and alpha 1-antichymotrypsin (ACT) were measured pre-operatively. The estimated median survival of patients with both raised CEA and ACT was only 5 weeks in contrast to 64 weeks for those with both proteins normal. An intermediary group with one of these proteins raised and the other normal had an estimated median survival of 15 weeks. Similar results were obtained by considering a combination of CEA with either AGP or CRP. For these data the results were not explicable in terms of associations between survival time and patient's age, stage, operative procedure, histological classification or site of primary tumour."} +{"text": "The expression of complex carbohydrates recognised by Helix pomatia lectin has been shown to predict unfavourable prognosis in breast and other cancers. It has been suggested that the prognostic significance of HPA binding may be through recognition of either Tn epitope or blood group A antigen GlcNAc-->R). In this study, the expression of glycoproteins terminating in alpha-GalNAc residues was investigated immunohistochemically using HPA and two monoclonal antibodies--BRIC 66 and BRIC 111 (anti-Tn). In paraffin sections, 74/87 (85%) of breast cancers expressed HPA-binding ligands, while 28/87 (32%) were positive for BRIC 66 binding and 25/87 (29%) expressed Tn. Distribution of staining patterns were distinctive and different with the three markers. BRIC 66, BRIC 111 and HPA binding to glycoproteins derived from breast cancer homogenates and to blood group A and Tn positive glycoproteins in Western blots confirmed the immunohistochemistry data. The results suggest that the prognostic significance of HPA binding in breast cancer is unlikely to be simply through recognition of blood group A antigen or Tn epitope on cancer cells. Breast cancers may express a complex profile of related but distinct glycans sharing similar terminal immunodominant sugar GalNAc, which may be implicated in aggressive biological behaviour."} +{"text": "The transformation of Wistar rat embryo cells in vitro has been studied in passaged cultures using two criteria for transformation: (1) the ability of cells to form colonies in soft agar and (2) the ability of cells to form tumours in young syngeneic animals. In general there was good correlation between the two criteria. Spontaneous transformation was observed in all untreated cultures by 44 weeks although, by not allowing the cells to become confluent, the tendency was for cultures to transform earlier (i.e. 15-21 weeks). It was noticeable that despite untreated cultures having been in vitro for different lengths of time, most cultures transformed after a similar number of passages (42-50). Treatment of the embryo cells with the alkylating agent nitrosomethylurea (NMU) or benzopyrene (BP) sometimes resulted in transformation after a shorter period in vitro than the controls (minimum 12 weeks) although some treated cultures took longer. Transformed cells produced transplantable fibrosarcomata in syngeneic hosts and those arising from NMU transformed cells were histologically different from those arising from spontaneously transformed cells. The significant of spontaneous transformation in in vitro rat cell transformation systems is discussed."} +{"text": "P < 0.0001). However, TIMP-1 expression was not increased in NPA and SW579 cells, both of which are derived from poorly differentiated thyroid tumours. Immunohistochemical study showed strong TIMP-1 staining in the stroma cells of advanced stages of carcinomas. Overexpression of TIMP-1 by gene transfer resulted in a significant suppression of the malignant phenotype of NPA cells as judged by an in vitro tumour invasion assay. These results suggest that high levels of TIMP-1 transcripts in advanced stages of thyroid carcinoma likely come from stroma rather than thyroid cancer cells, and TIMP-1 may function as a thyroid tumour invasion/metastasis suppressor. \u00a9 1999 Cancer Research CampaignTumour cell invasion and metastasis is a multistep process that involves the degradation of extracellular matrix proteins by matrix metalloproteinases (MMPs). Tissue inhibitors of metalloproteinases (TIMPs) act as negative regulators of MMPs and thus prevent tumour cell invasion and metastasis by preserving extracellular matrix (ECM) integrity. In the present study we examined the expression of one member of TIMPs, TIMP-1, in 39 thyroid tumour specimens and two thyroid carcinoma cell lines (NPA and SW579). We also investigated the effect of high TIMP-1 expression on the invasive potential of NPA cells. Northern blot analysis showed that TIMP-1 mRNA levels correlated directly with tumour aggressiveness: the highest number of TIMP-1 transcripts was found in stages III and IV vs benign goitre ("} +{"text": "Rh2(tfacam)4 was tested both in vitro (U937 and K562 human leukemia cells and Ehrlich ascitic tumor cells) and in vivo for cytostatic activity and lethal dose determination, respectively.

Protection (reappearance of a shoulder region) could also be seen when cysteamine was added at later incubation times. These changes in toxicity were accompanied by changes in drug metabolism, as evidenced by radiochromatograms of cell extracts obtained after treatment with 14C-labelled MISO. In contrast, radiochromatograms obtained from cells treated with toxic levels of MISO (75 mM) under aerobic conditions indicated no drug metabolism. Both toxicity and drug metabolism could be immediately halted by introducing O2 during hypoxic exposure to MISO. These observations are discussed in terms of a possible model for the metabolism-mediated toxicity of MISO and the roles which sulphydryls and O2 may play."} +{"text": "Optimized functional results are difficult to achieve following hand injuries. This prospective study was undertaken to evaluate the functional outcome after surgical stabilization of metacarpal and phalangeal fractures.Forty-five fractures of digits of hand in 31 patients were managed by surgical stabilization. Five fractures were fixed with closed reduction and percutaneous Kirschner wire fixation; 10 with external fixator; 26 with open reduction and Kirschner wire fixation; and four with open reduction and plate and screw or screw fixation.Final evaluation of the patients was done at the end of three months. It was based on total active range of motion for digital functional assessment as suggested by the American Society for surgery of hand. Overall results were excellent to good in 87%. Better total active range of motion (excellent grade) was observed in metacarpal fractures (47%) versus phalanx fractures (31%); closed fractures (57%) versus open fractures (27%); and single digit involvement (55%) versus multiple digits (29%). Excellent total active range of motion was observed with all four plate and screw/ screw fixation technique (100%) and closed reduction and percutaneous kirschner wire fixation (60%). Twenty-two complications were observed in 10 patients with finger stiffness being the most common.Surgical stabilization of metacarpal and phalangeal fractures of hand seems to give good functional outcome. Closed fractures and fractures with single digit involvement have shown a better grade of total active range of motion. Fractures of metacarpals and phalanges constitute between 14-28% of all visits to the emergency department.Forty-five metacarpal and phalangeal fractures of the hand in 31 patients aged 14 yrs or more were included in the prospective study conducted during the period 2004-2005. Unstable metacarpal and phalangeal fractures, intraarticular fractures, avulsion fractures, fracture dislocations and open fractures with sharp and clean wounds were included in the study. An unstable fracture was defined as one in which the patient was able to move the adjacent joints by less than 30% of the expected normal range of motion.The fractures were reduced and fixed using various implants including Kirschner wires, external fixators, plates or screws depending on fracture site, configuration and associated soft tissue damage. The fractures were divided into four groups depending on the type of internal fixation.Group I (n=5): The closed reduction and percutaneous Kirschner wire fixation was done in patients with fractures of the middle phalanx, proximal phalanx and metacarpal when closed reduction was possible.Group II (n=10): Open/closed reduction and external fixation was performed for open fractures with sharp and clean wounds.Group III (n=26): Open reduction and Kirschner wire fixation was done in fractures where closed reduction was not possible Figures \u20134. RetroGroup IV (n=4): Here open reduction with plate and/or screw fixation was performed for long oblique or spiral fractures of both metacarpals and phalanges Figures \u20138. The aThe hand was kept elevated and patients were encouraged to perform movements of the fingers and hand to prevent edema and stiffness. Antibiotics were given for 48h and prolonged in cases of open fractures. The Kirschner wires and external fixation devices were removed between 3 to 6 weeks. Active assisted mobilization was started after removal of Kirschner wire / external fixator usually at three to six weeks. Wax bath and contrast bath were given. Continuous passive motion (CPM) was not used. Patients were followed weekly for the first month and fortnightly for the next two months before final evaluation at three months.The mean age of the patients was 35.6 years (range 14-74 years). The most common mode of trauma was assault and roadside accidents (60%). In all, 43 digits were involved and there were a total of 45 fractures. Twenty-two patients had only a single digit involvement while two digits were involved in six patients and three digits in three patients. Fracture site and configuration in metacarpal and phalanges is shown in The functional outcome after fracture treatment was assessed by calculating total active range of motion (TAM).Metacarpal fractures (n=32) had an excellent n=15, 47%); and good TAM in 94% of fractures [Figures 5, 47%; aOverall end results of hand fractures in 31 patients managed by surgical stabilization were excellent in 14 (45.16%); good in 13 (41.93%); fair in three (9.68%); and poor in one(3.23%).A total of 22 complications were observed in 10 paResults in various groups according to TAM are tabulated in Many factors, such as delicate handling of tissues, preservation of gliding planes for tendons, prevention of infection and early and appropriate physiotherapy other than accurate reduction and fixation affect recovery of good mobility.5et al.et al.A higher incidence of excellent TAM n=13, 57%) was observed in closed fractures as compared to open fractures n=6, 27%).

Of the five fractures treated, three achieved excellent TAM (60%). Belskey et al.et al.External fixator was used for surgical stabilization of 10 open fractures. Advantage of external fixation is that no joint transfixation is required and hence patient does not develop any stiffness of the adjacent joints. Sixty per cent (n=6) of the fractures treated by this technique achieved excellent to good TAM. The results are comparable to those reported by FreelandOpen reduction with Kirschner wire fixation was done for stabilization of 26 fractures using three different techniques. (a) Retrograde insertion of Kirschner wire (n=16) with transfixation of joint was first advocated by Vomsaal.Open reduction and plate fixation was done in two fractures and two patients were treated with screw fixation. Excellent TAM was obtained in all four fractures treated by these techniques. Bosscha and SnellenFinger stiffness was the most commonly observed complication in the present series. Only one case of open fracture developed superficial infection. None of the cases developed osteomyelitis. Two patients with multiple fractures developed angulation at fracture site as the Kirschner wire was removed four weeks postoperatively before any radiological union. The movements, however, were almost full at all joints. Two cases of multiple fractures developed hypertrophic nonunion after Kirschner wire fixation. The cause was thought to be inadequacy of Kirschner wire fixation, which cannot check movements at fracture site completely. Ikuta and Tsugeet al.The results of the present study following surgical stabilization of fractures of metacarpals (94% excellent to good) and phalanges (54% excellent to good) were observed to be superior to those reported by Duncan Limitation of the study: The sample size is very small in some groups for statistical comparison.Surgical stabilization of metacarpal and phalangeal fractures of the hand seems to give good functional outcome. Closed fractures and fractures with single digit involvement are important determinants to achieve a better grade of total active range of motion."} +{"text": "The concentration of bound sialic acid in the sera of 56 normal subjects and 65 subjects with breast cancer was measured, in order to determine (1) whether serum sialic acid concentrations are raised in breast cancer and (2) whether the concentration of sialic acid in serum reflects tumour stage. The amount of sialic acid in serum was compared to serum carcinoembryonic antigen (CEA) values. Urinary hydroxyproline and serum alkaline phosphatase concentrations were used as indicators of bone and liver involvement. Erythrocyte sedimentation rate (ESR) was also measured. Significantly elevated serum sialic acid concentrations were found in breast cancer, and showed correlation with tumour stage. Serum sialic acid values did not correlate with CEA values. The results suggest that measurement of serum sialic acid concentrations may be of adjunctive value in assessing tumour stage."} +{"text": "We have studied the incidence of microsatellite instability at three trinucleotide repeats and seven dinucleotide repeats from five chromosomal regions, in a group of 30 mammographically detected 'early' invasive breast cancers and correlated its occurrence with clinicopathological parameters. The myotonic dystrophy (DM-1) trinucleotide repeat was analysed in 48 additional cases. In 4 out of 78 (5%) paired tumour-normal DNA samples we found evidence of somatic microsatellite instability at DM-1: a novel allele of a different size was seen in the tumour DNA which was not present in the normal DNA sample. All four tumours that showed evidence of instability were from the core group of 30 cases (13%) and were well or moderately differentiated, oestrogen receptor-positive, infiltrating ductal carcinomas. Two of these tumours were unstable at nine of ten loci studied, both trinucleotide and dinucleotide repeats. DNA prepared from different normal tissues showed no evidence of instability, for all four instability cases. These data indicate that microsatellite instability is specific to the tumour DNA and is an early event in the genesis of some sporadic breast cancers."} +{"text": "To date, cytogenetic studies on pancreatic carcinoma are rare, and little is known about the frequency of cytogenetic aberrations in primary carcinomas compared with metastatic tumour cells. We therefore evaluated the frequency of chromosomal aberrations in 12 primary pancreatic carcinomas and in effusion specimens from 25 patients with pancreatic cancer by using interphase fluorescence in situ hybridization (FISH) and a panel of four centromeric probes. Hyperdiploidy and chromosomal imbalances, predominantly affecting chromosome 8, were a constant finding in metastatic effusion cells, whereas concordant gain of chromosomes or relative loss of chromosome 18 characterized primary pancreatic carcinomas. The potential role of oncogenes located on chromosome 8 for pancreatic cancer progression was further investigated by double-hybridization studies of aneuploid effusion cells with a probe to 8q24 (MYC) and a centromeric probe to chromosome 8, which demonstrated amplification of the MYC oncogene in two of ten cases (20%). Finally, a potential application of basic findings in the clinical setting was tested by searching for micrometastatic cells in effusions from pancreatic cancer patients primarily negative by FISH. Two-colour FISH in combination with extensive screening seems to be a useful tool to unequivocally identify micrometastatic cells by demonstrating hyperdiploidy and intranuclear chromosomal heterogeneity."} +{"text": "Diabetic maculopathy, the leading cause of vision loss in patients with type 2 diabetes, is characterized by hyper-permeability of retinal blood vessels with subsequent formation of macular edema and hard exudates. The degree of hyperglycemia and duration of diabetes have been suggested to be good predictors of retinal complications. Intervention studies have determined that while intensive treatment of diabetes reduced the development of proliferative diabetic retinopathy it was associated with a two to three-fold increased risk of severe hypoglycemia. Thus we hypothesized the need to identify downstream glycemic targets, which induce retinal vascular permeability that could be targeted therapeutically without the additional risks associated with intensive treatment of the hyperglycemia. Betacellulin is a 32 kD member of the epidermal growth factor family with mitogenic properties for the retinal pigment epithelial cells. This led us to hypothesize a role for betacellulin in the retinal vascular complications associated with diabetes.A disintegrin and metalloproteinase (ADAM)-10 which plays a role in the cleavage of betacellulin was seen in the retinas of diabetic mice and humans.In this study, using a mouse model of diabetes, we demonstrate that diabetic mice have accentuated retinal vascular permeability with a concomitant increased expression of a cleaved soluble form of betacellulin (s-Btc) in the retina. Intravitreal injection of soluble betacellulin induced retinal vascular permeability in normoglycemic and hyperglycemic mice. Western blot analysis of retinas from patients with diabetic retinopathy showed an increase in the active soluble form of betacellulin. In addition, an increase in the levels of These results suggest that excessive amounts of betacellulin in the retina may contribute to the pathogenesis of diabetic macular edema. The incidence of diabetes world-wide, is expected to reach epidemic proportions by 2025. Progression of diabetic retinopathy often results in diabetic macular edema, which is a consequence of the breakdown of the blood-retinal barrier, increased retinal vascular permeability and leakage of plasma from small blood vessels in the macula leading to loss of central vision. While epidemiological studies have suggested that glycemic control plays a major role in the development of vascular complications of diabetesBetacellulin (BTC) is a 32 kD member of the epidermal growth factor (EGF) family that was originally isolated from the conditioned medium of a mouse pancreatic \u03b2-cell tumor lineRecombinant human VEGF was a kind gift from Genentech, CA and recombinant betacellulin was purchased from R&D.

Post mortem human eyes were obtained from he National Disease Research Interchange (NDRI), Philadelphia. Postmortem time ranged from 3\u201310 hours.Lysates from mouse or human retina prepared using sonication on ice with RIPA buffer (Boston Bioproducts) containing EDTA free protease inhibitors (Roche) were subjected to SDS-PAGE. Proteins were probed with antibody and detected with either a HRP-conjugated anti-rabbit or anti mouse IgG antibody followed by ECL. The blots were restripped with Restore\u2122 solution (Thermo Scientific) for 30 minutes and reprobed as indicated.6\u20138 week old C57BL6 mice were used in this study. The animals were cared for in accordance with the ARVO statement for the Use of Animals in Ophthalmic and Vision research. All experimental procedures used aseptic sterile techniques and were approved by the Animal Care and Use Committee of the Cleveland Clinic (ARC08792).6\u20138 week old mice were rendered diabetic with 3 consecutive daily intraperitoneal injections of STZ (55 mg/Kg) freshly dissolved in citrate buffer (pH 4.5). Control mice were given injections of buffer alone. Development of diabetes (defined by blood glucose greater than 250 mg/dl) was confirmed 1 week after the initial injection (One Touch\u00aeltra\u00aeTest Strips and One Touch\u00aeUltraMini\u2122glucometer).Vascular permeability in the retina was quantitated after 3\u20134 weeks of diabetes using an Evans blue quantitation technique as described previously Steptozotocin-induced diabetic mice with hyperglycemia (fasting blood sugar \u2265200 mg/ml) were examined for increases in retinal vascular permeability using an Evans Blue leakage assay. As described previously To determine if the increase in soluble active betacellulin seen in diabetic mice could contribute to increased vascular permeability we examined whether increased concentration of betacellulin in the retina could induce retinal vascular leakage in normal mice. Intravitreal injections of increasing doses of recombinant soluble betacellulin (0\u2013300 ng) resulted in increased retinal hemorrhage and diabetic macular edema (DME), we wanted to determine if the effect of betacellulin was VEGF-dependent.

In the year 2000 about 10 million new cases were registered, while 6.3 million people died from cancer worldwide. Stamps are regarded as a very useful and educative tool in fighting cancer by creating awareness and raising money for treatment and research. This year (2003) is the seventy-fifth anniversary of the issue of the first anticancer stamps in 1928, so an up-to-date review of the field of oncophilately is timely. Cancer is posing a serious social and economic problem globally since it was estimated by various organisations including It is necessary to take effective preventive measures and cancer awareness among the general population is essential. It is universally recognised that the anticancer stamps can play an excellent role in various ways as to create awareness and to collect money for treatment and research. This is because philately or stamp collection is still one of the most popular hobbies. Due to their universal circulation and appeal, stamps are powerful and effective messengers. It is also possible to use stamps issued for some other purposes in describing various aspects of cancer as will be exemplified later on. Only one report and two Five Swedish stamps on King Gustaf V issued in 1928 are regarded as the first anticancer stamps because the entire amount collected from sales was donated for cancer control (stamp 2). This was followed by a set of three Danish stamps issued in 1929 (stamp 3). Norway is the third country with a semipostal issue in 1931 (stamp 4) in the aid of Norwegian Radium Hospital. Since then, numerous countries have published several regular or semipostal stamps (stamps 5\u20138). Record shows that by the year 1964, 46 countries had issued 110 stamps and by tStamps are available on lung cancer (stamp 13), which is the most common cancer in terms of both incidence and mortality in 2000 . It is tBreast cancer is the most prevalent cancer in the world among females in 2000 . Many stFigure 1is stamp .Stamps have also been published on other cancers like prostate cancer . Passive smoking is also very dangerous. Evidence suggests that nonsmoking women married to smokers experience an excess risk of developing lung cancer in the order of 20%. A Japanese stamp may be used to illustrate this aspect (stamp 24).Excessive drinking causes liver, oral, pharynx, larynx and oesophageal cancers, and may increase the risks of colorectal and breast cancers. Simultaneous drinking and smoking habits are much more dangerous. Alcoholic beverages consumption potentiates the effects of tobacco smoking on cancers of the mouth, pharynx, oesophagus and larynx and has been estimated to account for about 3% of all cancer deaths. Stamps issued by many countries warn people about the use of alcohol (stamps 25 and 26).The British Surgeon Dr Percivall Pott demonstrated the earliest example of occupational cancer in 1775, showing a greater incidence of scrotal cancer among young chimneysweepers who were exposed to tar. Lord Shaftesbury, the great social reformer, worked for the well-being of these poor lads. A British stamp is available in his memory, depicting the hand of a chimneysweeper holding the brush (stamp 27). The stamp showing a picture of aniline (stamp 28) illustrates the need for care to be taken to minimise exposure to this chemical, because as early as in 1895, Rehn was the first to observe increased rate of bladder cancers among aniline dye workers. The stamp 29 describing the structure of benzene may be similarly used to show the need to take care in handling benzene, since it is proved to be a potent human carcinogen causing leukaemia with a latency period of about 15\u201320 years. It is widely used as a solvent in leather, petroleum and other industries. Polyaromatic hydrocarbons (PAH) are found in exhaust gases from automobiles run by petrol and diesel, from railway locomotives and in smoke, dust and exhaust gases from various factories. It is advisable to use protection to prevent inhaling of exhaust gases from automobiles as described in a Swedish stamp (stamp 30).92235U (stamp 31) and development of cancer dates from early observations on survivors of the atomic bombs in Japan.The relation between ionising radiation from various sources including radioactive substances such as Ultraviolet radiation from sunlight is the major risk factor for skin cancers and that of lip. Stamps showing sunrays and flares (stamp 32) may be used to make people aware of the dangers of overexposure to sunrays.Figure 3Links have already been established between some viral infections and the development of cancers such as Epstein\u2013Barr virus and Burkitt lymphoma, hepatitis B and C and hepatocellular (liver) carcinoma, human papilloma virus (HPV) and cervical cancer in females, human immunodeficiency virus (HIV). AIDS patients infected with HIV have higher incidence and death rates from malignancies like Kaposi's sarcoma, non-Hodgkin's lymphoma, etc. Hence awareness regarding HIV infection is very important from a cancer preventive perspective also. So far about 65 countries have issued over 120 anti-AIDS stamps (e.g. stamps 33\u201336).Catharanthus rosea) may be used to point out that some important alkaloidal drugs like vincristine and vinblastine have been isolated from the plant (stamp 40). Taxol has been isolated from Taxus brevifolia (Pacific Yew tree) and Taxus baccata (stamp 41).Figure 4Nowadays, three chief treatment modalities \u2013 surgery, radiotherapy and chemotherapy \u2013 are used in all sorts of combinations. Bangladesh has issued a beautiful stamp depicting the picture of a crab attacked with these three modes of treatment (stamp 37). One can find individual stamps on surgery (stamp 38), radiotherapy (stamp 39) and chemotherapy. Anticancer drugs are obtained by chemical synthesis or from natural sources such as plants.

The protective effects of dietary fibre present in vegetables against a number of cancers like colorectal, oesophageal and stomach have been demonstrated. Hence it is advisable to eat vegetables rich in roughage like jackfruit (stamp 49), beans (stamp 47), ladies finger, etc.Curcuma longa (stamp 50) is the source of turmeric, which contains the yellow natural colouring agent namely curcumin which may have chemopreventive properties have been shown in lab studies to have antitumour as well as tumour promotion inhibitory activities. Onions and ginger have also been shown to possess similar properties.Constituents of Camellia sinensis (stamp 52). Tea is one of the most ancient and next to water the most widely consumed liquid in the world.

Obesity (stamp 53) is associated with the endometrium, breast, kidney, colorectal and gallbladder cancers. Thus it is advisable to maintain a healthy body weight.An active lifestyle is recommended. Physical activity decreases the risk of colon and breast cancers. Walking, cycling, gardening, household chores, climbing the stairs, practising yoga (stamp 54), etc. are recommended.Early detection of cancer is very important to save lives (stamp 55). Annual check-up (stamp 56) of oral cavity, skin, lymph nodes, routine examinations of blood for detection of any abnormalities in its constituents (stamp 57) and chest X-ray (stamp 58) are internationally accepted tests for earlFor women: Breast awareness is important (Indian stamp 59) and clinical breast examination by a physician may be helpful where there is no national screening programme. It is also suggested to carry out mammography (stamp 60). Cervical PAP test (stamps 61 and 62) should be carried out in adult females at regular intervals.For men: Population-based prostate-specific antigen (PSA) testing can reduce mortality in countries where urological follow-up and treatment are available. US Postal Service issued a semifiscal stamp in 1998 on this aspect , electron microscope (stamp 64), X-ray instruments (stamp 65), radiotherapy instruments (stamps 66 and 67), ultrasonography (USG) (stamp 68), computed topographic (CT) scanning (stamp 69), magnetic resonance imaging (MRI) (stamp 70), nuclear medicine imaging (scintigraphy) (stamp 71), mammography, etc. In 1992, Macedonia had brought out a set of four stamps with the message of early cancer detection in one of them and with the picture of diagnostic equipment in the other three (stamps 72\u201375).Many scientists and physicians appear on stamps for their outstanding contribution in the fight against cancer. WC Roentgen (1845\u20131923) \u2013 discoverer of X-rays in 1895 and the first recipient of the Nobel prize in 1901 (stamp 76). Henri Becquerel (1852\u20131908) (stamp 77) \u2013 discoverer of the phenomenon of spontaneous emanations later termed radioactivity by Madame Marie Curie. Radiotherapy has originated from this discovery. Madame Marie Curie (1867\u20131934) and Pierre Curie (1859\u20131906) \u2013 world-renowned French scientists who discovered radium in 1898, which was the first radioactive substance used for the treatment. Madame Curie appeared in about 100 stamps either alone or with her husband Pierre Curie (stamps 81 and 82). In 1938, France and its 21 colonies issued the latter stamps (81 and 82) as a tribute to the 40th anniversary of this discovery. The surtax of these stamps was given to the International Union Against Cancer. Pierre Curie was also remembered alone in some stamps. Irene Joliot Curie (1897\u20131956), elder daughter of Madame Curie, and Frederic Joliot (1900\u20131958) son-in-law of Madame. Curie \u2013 joint discoverers of artificial radioactivity (stamp 83). Based on their discovery, a number of artificial radioisotopes have been prepared some of which find use in cancer. George N Papanikolaou (1883\u20131962) (stamps 62 and 84) \u2013 discoverer of PAP test for early diagnosis of cervical cancer that has saved the lives of millions of women worldwide. Moritz Kaposi (1837\u20131902) (stamp 85) \u2013 famous physician who identified in 1872 a special type of sarcoma that was named after him as Kaposi's sarcoma. Rudlof Virchow (1821\u20131902) (stamp 86) \u2013 founder of cellular pathology. He discovered and named gliomas and giant cells. He had also named many common tumours.Postage stamps and cancellations are available on world-famous organisations like International Union Against Cancer (UICC) (stamps 81 and 82), World Health Organization (WHO) (stamp 87), etc.Starting from 1933, UICC organises International Cancer Congress every fourth year where scientists, clinicians, nurses, etc. from all over the world meet. Special commemorative stamps have been issued on these occasions by various countries: 8th held in Russia in 1962 (stamp 88), 9th held in Japan in 1966 (stamps 39 and 89), 12th held in Argentina in 1978 (stamp 90), 14th held in Hungary in 1986 (stamp 85) and 16th held in India in 1994 (stamp 91).Thus our fight against cancer will continue till we achieve success (stamp 92). Research is ongoing globally, and newer concepts, improvements in therapeutic modalities and new drugs are being added continuously. Recent global efforts in DNA decoding (stamp 93) and human genome mapping leading to genome genetic engineering (stamps 94 and 95) will help to identify and repair the defective genes (gene therapy of cancer). The message that should reach everybody is that cancer will be defeated \u2013 sooner or later \u2013 as is beautifully demonstrated in a French stamp issued in 1970 picturing a smiling lady cured of cancer overcoming the threat of death displayed underneath (stamp 96).It is therefore convincingly demonstrated that, in addition to specific anticancer stamps, various other stamps can be used to describe different aspects of cancer. The significant role of stamps in raising awareness among people regarding this dreadful disease has been highlighted."} +{"text": "The ultrastructure of 16 tumours derived from spontaneously transformed cell lines established from young and old C57 and C3H mouse organs is described. Three types of tumour were found: myxoid (fibrosarcomatous), consisting of cells with long processes and much interstitial material; leiomyomatous, consisting of a bundle of smooth muscle-like cells with less interstitial material; or epithelial-like consisting of closely packed round cells with little interstitial material. The cell types in the tumours were similar to those found in the tissue culture cell lines from which they were derived."} +{"text": "The Src family kinases possess two sites of tyrosine phosphorylation that are critical to the regulation of kinase activity. Autophosphorylation on an activation loop tyrosine residue (Tyr 416 in commonly used chicken c-Src numbering) increases catalytic activity, while phosphorylation of a C-terminal tyrosine (Tyr 527 in c-Src) inhibits activity. The latter modification is achieved by the tyrosine kinase Csk , but the complete inactivation of the Src family kinases also requires the dephosphorylation of the activation loop tyrosine. The SH3 domain of Csk recruits the tyrosine phosphatase PEP, allowing for the coordinated inhibition of Src family kinase activity. We have discovered that Csk forms homodimers through interactions mediated by the SH3 domain in a manner that buries the recognition surface for SH3 ligands. The formation of this dimer would therefore block the recruitment of tyrosine phosphatases and may have important implications for the regulation of Src kinase activity. Members of the Src family of protein tyrosine kinases, such as c-Src, Lck, Fyn and Hck, are key players in many signalling pathways that regulate cell growth, proliferation and motility The kinase domain of Csk is responsible for the recognition of the Src family kinases as its specific substrates, resulting in phosphorylation of the C-terminal tail The SH3 domain of Csk interacts with several tyrosine phosphatases Pursuing the observation that Csk is dimeric at high protein concentration in vitro FL) migrates as a dimer by size exclusion, the removal of the SH3 domain (CskSH2KD) or the SH3 and SH2 domains (CskKD) resulted in proteins that no longer appear to dimerize and instead elute as apparent monomers by gel filtration , CskSH2KD (residues 68\u2013450) and CskKD (residues 187\u2013450) were expressed in bacteria and purified as described The constructs of human Csk, CskPurified Csk proteins were subjected to analytical gel filtration using a Superdex S200 column or SMART S200 column .

Archival formalin-fixed and paraffin-embedded material was analysed by immunohistochemistry. ER and PR were measured with monoclonal antibodies and the peroxidase-antiperoxidase method and a score was calculated as for breast carcinoma based on both the percentage of positive tumour cell nuclei and the staining intensity. ER were seen in 15 (71%) and PR in 20 (95%) of tumours respectively. ER expression was scored as high in three (14%), moderate in four (19%), and low in eight (38%) tumours. Six (29%) tumours did not stain for ER and all of these were positive for PR. PR expression was scored as high in eight (38%), moderate in ten (47%) and weak in two (10%) LGSSs. Only one (5%) LGSS did not stain for PR (this tumour was positive for ER). ER and PR expression in LGSS is heterogeneous. This may have implications for hormone therapy in the management of these tumours. These results suggest that ER and PR should be routinely quantified in LGSSs by immunohistochemical methods. \u00a9 2000 Cancer Research Campaign"} +{"text": "The objective of the study was to review the natural history of patients with a malignant pleural effusion but without obvious evidence of a primary, to assess the value of investigations used to look for a primary and to assess the response to palliative chemotherapy. This was done by a retrospective study of patients' notes at the Lung Unit, Royal Marsden Hospital, Sutton, Surrey. Improvement in tumour-related symptoms (and duration) on chemotherapy was assessed by the patient before the first course of chemotherapy and following each course using simple descriptive criteria as follows: (1) complete disappearance of symptoms (CR); (2) good improvement in symptoms (PR); (3) minor or no change in symptoms (NC); (4) worse symptoms (PD). Pleural effusion objective response (and duration) according to Hamed definition: success defined as a continued absence of reaccumulation of pleural fluid on all follow-up radiographs; any reaccumulation was regarded as a treatment failure. Overall survival was measured from the date of histological/cytological diagnosis to death. The study included 42 patients, 27 males and 15 females with a median age of 55 years. A primary was found in 15 patients (36%), and considered to be lung cancer. A total of 11/32 (34%) had a thoracic computed tomography (CT) scan with abnormalities compatible with a diagnosis of lung primary. When thoracic CT scan was negative, fibre optic bronchoscopy was always negative (0/13). Abdominal and pelvic CT scan, abdominal ultrasound, pelvic ultrasound and mammograms failed to reveal the primary. Twenty-three patients underwent local treatment and 37 received systemic chemotherapy. A total of 29/37 (78%) patients achieved symptomatic improvement and 32/37 (86%) an objective response of their pleural effusion on chemotherapy . The median survival of the whole group was 12 months (3-60+ months). In this series the thoracic CT led to a diagnosis of lung primary in 34% of the cases. Other radiological examinations and bronchoscopy were unhelpful. Chemotherapy achieved symptom relief in 78% of patients."} +{"text": "Analysis of human tumour-derived cell lines has previously resulted in the identification of novel transformation-related elements and provided a useful tool for functional studies of different genes. To establish the utility of such cell lines as indicators of change relevant to urothelial cancer, we have characterised the expression of five genes within a panel of human bladder carcinoma cell lines. Using single-strand conformation polymorphism (SSCP) and direct sequencing, p53 mutations were identified in 7/15 (47%) cell lines reflecting events reported in bladder tumours. Immunohistochemical analysis of p53 in cultured cells and in paraffin-embedded sections of xenografts from the cell line panel revealed discordant results. An absence of p53 nuclear staining was associated with an exon 5 mutation in EJ and with multiple p53 mutations found in J82. Two cell lines positive for p53 staining in the absence of detectable mutation displayed overexpression of MDM2 in Western blot analysis. Loss or aberrant Rb expression was recorded in 5/15 cell lines. Absence of E-cadherin was recorded in 5/15 cell lines with loss of alpha-catenin in immunoprecipitated E-cadherin complexes of CUBIII. Western blot analysis of APC revealed a truncated protein in 1/15 (CUBIII) cell lines. The characterisation of oncogenic events within this panel of human bladder carcinoma cell lines establishes a representation of change observed in bladder tumours and better defines the genotypic background in these experimental human cell models of neoplastic progression."} +{"text": "Two human deaths caused by Australian bat lyssavirus (ABL) infection have been reported since 1996. Information was obtained from 205 persons (mostly adults from south Brisbane and the South Coast of Queensland), who reported potential ABL exposure to the Brisbane Southside Public Health Unit from November 1,1996, to January 31, 1999. Volunteer animal handlers accounted for 39% of potential exposures, their family members for 12%, professional animal handlers for 14%, community members who intentionally handled bats for 31%, and community members with contacts initiated by bats for 4%. The prevalence of Lyssavirus detected by fluorescent antibody test in 366 sick, injured, or orphaned bats from the area was 6%. Sequelae of exposure, including the requirement for expensive postexposure prophylaxis, may be reduced by educating bat handlers and the public of the risks involved in handling Australian bats."} +{"text": "Furthermore, strong correlations were found between the levels of both uPA and PAI-1 in the cytosols and their levels previously measured with ELISAs based on commercial reagents. In both Cox univariate and multivariate analysis, high cytosolic levels of uPA or PAI-1 were significantly associated with increased rates of relapse and death. The levels of uPA and PAI-1 in the pellet extracts also provided prognostic information, although to a lesser extent compared with the cytosolic extracts. The prediction of prognosis on the basis of uPA and PAI-1 assessed by an alternative ELISA once again emphasizes the established prognostic role and usefulness of these parameters in selection of breast cancer patients at high or low risk of recurrence. \u00a9 1999 Cancer Research CampaignTo evaluate the clinical relevance of urokinase-type plasminogen activator (uPA) and its type-1 inhibitor (PAI-1) measured by a recently developed enzyme-linked immunosorbent assay (ELISA), we analysed both components in samples derived from 892 patients with primary breast cancer (median follow-up 99 months). The assays were performed in cytosolic extracts as well as in corresponding detergent extracts of pellets obtained after ultracentrifugation, which was carried out when preparing the cytosolic fractions for routine steroid hormone receptor determination.

Based on these observations, we have developed a receptor scintigraphy using [123I]VIP as a radioligand. An initial series performed at our institution showed promising potential for visualization of various gastrointestinal adenocarcinomas by means of [123I]VIP. In this article, we now report the results obtained in 80 consecutive patients with colorectal adenocarcinoma. Eighty consecutive patients with histologically verified colorectal cancer underwent scanning by means of [123I]VIP . Thirteen patients were free of tumour after complete resection of Dukes' C cancer, eight patients presented with primary and 14 with locally recurrent tumours but were free of metastases. Ten patients had locally recurrent disease and liver, lung or lymph node metastases. Disease confined to organ metastases was present in 35 patients. The size of the primary or recurrent tumours ranged between 3 and 6 cm, and the size of metastases was between 1 and 13 cm in diameter. Scan results were evaluated independently by two nuclear medicine physicians in a blinded way, and results were then compared with computerized tomography (CT)scans not older than 4 weeks. Seven out of eight primary (87%) and 21 out of 24 (82%) locally relapsing cancers were imaged with [123I]VIP. Negative VIP scans were obtained in all 13 patients in whom the cancers had been curatively resected. All patients with lymph node metastases showed positive VIP scans (four out of four), and positive scans were obtained in 25 out of 28 (89%) patients with liver metastases and in two out of three cases with lung metastases. In four patients with relapsing cancer, the VIP scan indicated the presence of disease before CT, and in two patients the diagnosis of scar tissue instead of a local recurrence of rectal cancer as suggested by CT could be established. We conclude that [123I]VIP receptor scanning is a sensitive method for radioimaging of colorectal cancer with the potential to provide valuable additional information to conventional radiological methods."} +{"text": "To study pathophysiological roles of mesothelial barrier functions in protection against cancer cell invasion, we isolated mesothelial cells from the rat abdominal cavity and then cultured them with 10(-6)M all-trans-retinoic acid (RA) for 10 days. Mesothelial barrier function assessed by measuring transcellular electrical resistance (TER) and the expression of 7H6 tight junction-associated antigen at the cell border were induced by the treatment . Then we quantified the attachment and penetration of rat mammary cancer cells (SST-2 cells) into the mesothelial cell monolayer by prelabelling of the cancer cells with fluorescent dye and by observing optical sections at different heights using a laser confocal scanning microscope. When SST-2 cells were overlaid onto the mesothelial cell monolayer treated with RA, the number of cancer cells found at the basal level of the monolayer was significantly reduced. These results showed that enhanced mesothelial barrier function at least partially prevents the penetration of cancer cells into mesothelial cells and suggested that 7H6 antigen serves as a reliable immunocytochemical marker for monitoring mesothelial barrier function."} +{"text": "Anthracenyl-amino acid conjugates represent a novel chemical class of topoisomerase (topo) inhibitor. NU/ICRF 505 is a lead compound that stabilises topo I cleavable complexes and is actively cytotoxic at low microM concentrations. In this study, endonucleolytic DNA cleavage was used as a marker of apoptosis to investigate mechanisms of cell death produced by this compound. NU/ICRF 505 (5 microM) induced a substantial increase in the level of DNA fragmentation in HL60 cells but only after a 48 and 72 h drug exposure (compared with 6 h after treatment with camptothecin), as determined qualitatively by conventional gel electrophoresis and quantitatively by spectrofluorimetry. This effect was substantially reversed by co-treatment with zinc (1 mM). Subsequent studies with the human lung (NX002), ovarian (A2780) and colon (HT29) cancer cell lines yielded evidence of formation of higher molecular weight DNA fragments in NX002 and A2780 cells in response to NU/ICRF 505 (5 microM). Co-treatment with zinc (1 mM) caused a small decrease in DNA fragmentation. These data suggest that the induction of apoptosis may play an important role in the mechanism of cytotoxicity of NU/ICRF 505 in HL60 cells and that other pathways of cell death may also be operative in NX002 and A2780 in conjunction with apoptosis."} +{"text": "The relationship between the bioenergetic status of human glioma xenografts in nude mice and morphometric parameters of the perfused vascular architecture was studied using (31)P magnetic resonance spectroscopy (MRS), fluorescence microscopy and two-dimensional digital image analysis.

Intervascular distances and non-perfused area fractions varied greatly between tumours of the same line and tumours of different lines. The inorganic phosphate-nucleoside triphosphate (P(i)/NTP) ratio increased rapidly as mean intervascular distances increased from 100 microm to 300 microm. Two morphometric parameters - the percentage of intervascular distances larger than 200 microm (ivd200) and the non-perfused area fraction at a distance larger than 100 microm from a nearest perfused vessel (area100), - were deduced from these experiments and related to the P(i)/NTP ratio of the whole tumour.

In addition to histopathology, we examined: (1) the relationship between the occurrence of lung cancer and the amount of chromium (Cr) deposited in the lung as determined by atomic absorptiometry and (2) the chronological changes in five precancerous lung lesions followed by bronchoscopy till death. Twenty-one cancers were identified, including 16 lung tumours observed either during follow-up or at autopsy. Of these 16 tumours, 13 were found in six subjects, implying a high frequency of multiple cancers. Eleven (69%) out of the 16 tumours were of squamous cell type (including carcinoma in situ), this being twice as frequent as in age-matched controls. A further characteristic was predominance in the central part of lung (69%). The lung Cr burden was very much higher in patients with lung tumours than in those without (8-28 micrograms g-1). Five of the precancerous lesions followed by bronchoscopy originated at bronchial bifurcations. Four of these cases showed a return to normal histology at autopsy even without therapy, and the other did not progress."} +{"text": "Background: Morbidity and mortality after surgical treatment of bileduct stones increase with age and associated diseases. A proposed alternative therapy is endoscopic sphincterotomy (ES) with the gallbladder left in situ, and we elected to compare this option with standard open surgery in high-risk patients.Methods: 98 patients (mean age 80 years) with symptoms likely to be due to bileduct stones or a recent episode of biliary parcreatitis were randomised to be treated either by open cholecystectomy with operative cholangiography and (if necessary) bileduct exploration (n=48) or by endoscopic sphincterotomy alone (n=50).Findings: The procedure was accomplished successfully in 94% of the surgery group and 88% of the ES group, and there were no significant differences in immediate morbidity (23% vs 16%) or mortality (4% vs 6%). During mean follow-up of 17 months biliary symptoms recurred in three surgical patients, none of whom underwent repeat surgery, and in 10 ES patients, seven of whom had biliary surgery. By multivariate regression analysis endoscopic sphincterotomy was an independent predictor of recurrent biliary symptoms .Interpretation: In elderly or high-risk patients, surgery is preferably to endoscopic sphincterotomy with the gallbladder left in situ as a definitive treatment for bileduct stones or non-severe biliary pancreatitis."} +{"text": "Microsatellite instability (MSI) was examined at 36 loci, and found in 9 (43%) of the 21 prostatic cancers.

The aim of this study was to determine the current practice of surgeons in terms of access to and closure of the abdominal cavity in elective open surgery.Twelve surgical departments of the INSECT-Trial group documented the following variables for 50 consecutive patients undergoing abdominal surgery: fascial closure techniques, applied suture materials, application of subcutaneous sutures, subcutaneous drains, methods for skin closure. Descriptive analysis was performed and consensus of treatment variables was categorized into four levels: Strong consensus >95%, consensus 75\u201395%, overall agreement 50\u201375%, no consensus <50%.157 out of 599 patients were eligible for analysis (85 (54%) midline, 54 (35%) transverse incisions). After midline incisions the fascia was closed continuously in 55 patients (65%), using slowly absorbable , braided sutures with a strength of 1 . In the transverse setting the fascia was closed continuously in 39 patients (72%) with slowly absorbable braided sutures with a strength of 1 .In the present evaluation midline incision was the most frequently applied access in elective open abdominal surgery. None of the treatments for abdominal wall closure (except skin closure in the midline group) is performed on a consensus level. Approximately 700.000 open abdominal procedures are performed annually in Germany and 4.000.000 in the United States . DevelopThere is still controversy about the best strategy for abdominal wall closure due to inconsistent and incomplete evidence provided by several randomized controlled trials (RCT) -8 as wel1. Is midline incision still the most frequently applied access to the abdominal cavity in elective situations?2. Has consensus for abdominal wall closure already been established in surgical routine?The primary objective of this cross sectional study was therefore to identify current practice of abdominal cavity access and closure in elective surgery.Twelve of the 25 participating centres of the INSECT-Trial group agreed in contribution to data acquisition (see acknowledgment). The local ethics committees of participating centres granted ethical approval for the study These include hospitals of all levels of health care , thus ensuring representative study results. Surgeons at these hospitals were asked to assess surgical access and closure methods of 50 consecutive patients who underwent surgery at their service. Patients who underwent more than one operation during the study period were excluded.The study was designed as a cross-sectional cohort study and performed between July and August 2005. A standardized data entry form was designed in order to collect the following information: patient's gender and age, setting of surgery (elective vs. emergency surgery), surgical approach (open vs. laparoscopic surgery), history of previous abdominal surgery, type of applied abdominal incision (transverse vs. midline), suture material used for fascia closure , the technique used for fascia closure , the use of subcutaneous suture and subcutaneous drainage, and the method of skin closure. Classification of suture strengths was reported according to the United States Pharmacopeia XXII (1990).All data entry forms were sent in an anonymous fashion to the Study Centre of the German Surgical Society and analyzed accordingly using Statistical Analysis System (SAS) version 9.1. Descriptive statistics were used in univariate analyses.The treatment of patients were categorized into four levels of consensus according to a classification of Hoffmann et al. :1. Strong consensus: treatment applied in >95% of cases2. Consensus: treatment applied in 75\u201395% of cases3. Overall agreement: treatment applied in 50\u201375% of cases4. No consensus: treatment applied in <50% of casesA total of 599 patient data entry forms out of 600 with an equal distribution of genders and a mean age of 57 years (SD 19 years) were available for analysis. An open approach was chosen in 375 patients (63%), a laparoscopic in 224 patients (37%). After exclusion of patients with previous open abdominal surgery, an emergency procedure, and laparoscopic procedures, a total of 157 patients with primary elective laparotomy were available for further analysis , midline incisions were performed in 85 patients (54%), transverse incisions (crossing the midline) in 54 patients (35%) and miscellaneous incisions in 13 patients (8%).Fascia closure for midline incisions was performed with a continuous suture in 55 patients (65%) and interrupted sutures in 16 patients (19%), respectively. In 13 (15%) of these patients a combination of both techniques was applied. Monofilament sutures were applied for fascia closure in 51 patients (60%), braided sutures in 32 patients (38%). Non-absorbable sutures were chosen in four cases (5%), slowly absorbable sutures in 47 patients (55%), and moderately rapid absorbable sutures in 33 patients (39%). Sutures with the strength of 0 were used in two patients (2%), with strength of 1 in 48 patients (57%), and with strength of 2 in 31 patients (36%).Subcutaneous suture was performed in 48 patients (57%) and a subcutaneous drain was placed in 19 patients (22%). Skin closure of patients who received midline incisions was performed with staples in 67 cases (79%).In terms of consensus levels all technical features for closure of midline incisions met the level of \"overall agreement\", except the item of skin closure for which the level of \"consensus\" was reached Table .Abdominal fascia of patients who had a transverse incision (n = 54) was sutured continuously in 39 patients (72%), interruptedly in eleven patients (20%), and with a combination of both techniques in two patients (4%). Suture material with the strength was 0 were chosen in 6 patients (11%), with a strength of 1 in 30 patients (56%) and with a strength of 2 in 17 patients (31%). Monofilament sutures were applied for fascia closure of 25 patients (46%) and braided sutures for 27 patients (50%). In two patients (4%) non-absorbable sutures, in 22 patients (41%) slowly absorbable sutures, in 29 patients (54%) moderately rapid absorbable sutures, and in one patient (2%) rapidly absorbable sutures were applied.Thirty-nine patients (72%) received a subcutaneous suture; a subcutaneous drain was placed in 12 patients (22%). Skin closure of patients who received midline incisions was performed with staples in 39 cases (72%).All technical features for closure of transverse incisions reached the level of \"overall agreement\" Table .In the present analysis midline incision is still the most frequent access to the abdominal cavity in elective surgery. No consensus for fascia closure either for midline or transverse incisions in daily practice of abdominal surgery was detected (>75% of surgeons acting similarly). Use of staples for skin closure after midline incisions was the only item that reached the level of consensus.Our finding that midline incisions are the most frequently applied access in open abdominal surgery is in accordance with previous reports . While tThe lack of consensus for abdominal wall closure strategies after midline incisions demonstrates persistent uncertainty within the surgical community. Several RCTs -8 and meAccording to our data, there is no consensus in closure of transverse incisions either. Closure technique of the abdominal fascia with a continuous suture and skin closure with staples were the only items that almost reached the level of consensus (both performed in 72%). In contrast to midline incisions, however, so far no randomized trial has been solely conducted in order to investigate closure techniques in this setting. Hence, the ideal closure strategy is still to be determined. From some trials comparing closure techniques in midline incisions ,18,19 paThe results of our study might be affected due to bias. The participating hospitals of the INSECT-Trial who agreed to contribute to this study may be a subgroup of hospitals dedicated to clinical research and therefore act differently to other hospitals (e.g. surgeons agree to randomize their patients). However, it is unlikely that such an effect might have systematically shifted the results in favour of consensus.A cross-sectional consecutive data collection of real patient data seems to be the optimal design to answer our initial study questions. Selection bias within the hospitals is prevented due to a consecutive recruitment and measurement bias due to standardized data collection. Furthermore, surgeons of the INSECT-Trial group were trained in data collection during specific preparatory INSECT-Trial meetings . Other sCurrently, no clinical guidelines are available for abdominal wall closure after any type of incision. Further well designed pragmatic randomized controlled trials are necessary to support a development of such evidence-based guidelines and to change the current practice. Otherwise a reduction of incisional hernias seems unfeasible and treatment remains on the level of \"overall agreement\". The results of the recently published INSECT-Trial certainly contribute to the body of evidence on abdominal fascia closure techniques. FurtherIn conclusion, midline incisions were the predominant type of abdominal access in the present study of participating centers of the INSECT-Trial. There is no consensus regarding the strategy for closure of the abdominal fascia after midline and transverse incisions.The authors declare that they have no competing interests.NNR: Study design, data analysis and interpretation, drafting of the manuscript PK: Study design, data acquisition, data analysis, revsion of the manuscript.

While commercial solutions exist, implementation and validation are expensive and cumbersome. Frequent implementation of new features via point releases further complicates purchasing decisions by making it difficult to weigh the risk of non-compliance against the costs of too frequent upgrades. This presentation discusses a low-cost interim solution to the problem. While this solution does not address 100% of the issues raised by 21CFR11, it does implement and validate: (1) computer system security; (2) backup and restore ability on the electronic records store; and (3) an automated audit trail mechanism that captures the date, time and user identification whenever electronic records are created, modified or deleted. When coupled with enhanced procedural controls, this solution provides an acceptable level of compliance at extremely low cost."} +{"text": "The transcription factor, milk protein binding factor (MPBF/Stat5), is a member of the STAT family of signalling molecules which mediates prolactin signal transduction in lactating mammary gland by binding to GAS (gamma-interferon activation site) DNA elements. We have determined the levels of STAT factors in nuclear extracts from a variety of human breast tissues including carcinoma and normal 'resting' breast by electrophoretic mobility-shift assay. The results show that the level of STAT binding activity is low in normal 'resting' breast and benign lesions while carcinoma samples have significantly higher (P < 0.01) amounts of STAT binding activity. Supershift analysis suggests that Stat1 and possibly other members of the STAT family of signalling factors, including Stat3, are activated in breast cancer tissues."} +{"text": "The main results of these studies can besummarized as follows: (1) exogenous or endogenous catecholamines suppress PBL functions through alpha-2-receptor-mediatedmechanisms, lymphocytes of the spleen are resistant to adrenergic in vivo stimulation,(2) direct or indirect cholinergic treatment leads to enhanced ex vivo functions of splenic and thymic lymphocytesleaving PBL unaffected, (3) cholinergic pathways play a critical role in the \u201ctalking back\u201d of the immune system to the brain,(4) acetylcholine inhibits apoptosis of thymocytes possibly via direct effects on thymic epithelial cells, and maythereby influence T-cell maturation, (5) lymphocytes of the various immunological compartments were found to beequipped with the key enzymes for the synthesis of both acetylcholine and norepinephrine, and to secrete theseneurotransmitters in culture supernatantsFor several years, our group has been studying the"} +{"text": "Autoimmunity and inflammation are associated with marked changes in lipid and lipoprotein metabolism in SLE.

A significantly higher proportion of individuals in the control group (n = 147) had measurable GSTM1 than MM patients ; there was a higher proportion of positive phenotypes in general among women than among men.

The radiosensitivity of clonogenic cells in tumour biopsies was measured as surviving fraction at 2 Gy (SF2) using a soft agar assay. HAP1 expression levels were determined after staining of formalin-fixed paraffin-embedded tumour sections with a rabbit antiserum raised against recombinant HAP1. Both measurements were obtained on pretreatment biopsy material. All 25 tumours examined showed positive staining for HAP1, but there was heterogeneity in the level of expression both within and between tumours. The average coefficients of variation for intra- and intertumour heterogeneity were 62% and 82% respectively. There was a moderate but significant positive correlation between the levels of HAP1 expression and SF2 . Hence, this study shows that there is some relationship between intrinsic radiosensitivity and expression of a DNA repair enzyme in cervical carcinomas. The results suggest that this type of approach may be useful in the development of rapid predictive tests of tumour radiosensitivity."} +{"text": "Between January 1977 and January 1988, 19 patients with non-Hodgkin's lymphoma (NHL) involving the ileocaecal region were cared for by the CRC Wessex Medical Oncology Unit.

The commonest clinical presentation was with abdominal pain and a palpable mass in the right iliac fossa. Bulky (greater than 10 cm) disease was a particularly common feature, and complete surgical removal was possible in only seven patients. All patients had intermediate (18) or high grade (one) NHL using the Working Formulation. The commonest histological subtype was diffuse large cell. Seventeen patients received postoperative therapy, comprising local radiotherapy in one and combination chemotherapy in the remaining 16. Eleven of the 19 patients remain disease-free 6-60 months from diagnosis. Because of the high incidence of bulky disease at this site, postoperative therapy may be indicated, even for patients with apparently completely excised stage I disease."} +{"text": "Sir,We read with great interest the article by The diagnosis of chronic pancreatitis was based on the radiologic data obtained by means of either endoscopic retrograde cholangiopancreatography or computed tomography.DNA was extracted from 20\u2009ml of the serum by using the QIAmp Blood Kit (Qiagen) and the mutations in codon 12 of the K-ras gene were searched as described previously (BstNl restriction enzyme (PCR-RFLP).As positive controls, we used DNA from neoplastic tissues of 10 patients with pancreatic carcinoma by using the DNeasy Tissue Kit (Qiagen).

Use of this assay has provided the first direct evidence that TOP1 and RAD52 proteins are involved in the mode of action of bisdioxopiperazine ICRF compounds, which thus express a mode of action quite distinctive from the other known TOP2 inhibitors evaluated. The functional assay is based on a comparison of pairs of yeast differing in their phenotypes by specific traits: the expression or lack of expression of ectopic human DNA topoisomerase I, with or without that of the RAD52 gene. Amongst a series of anticancer agents, inhibitors of topoisomerase I (camptothecin) were identified as such in yeast expressing human topoisomerase I, whilst the presence or absence of RAD52 protein permitted the discrimination of compounds generating double-stranded DNA breaks, either directly (bleomycin) or involving DNA adduct formation (cisplatin), or indirectly with DNA damage mediated via inhibition of the topoisomerase II enzyme (etoposide). Notably, however, both the RAD52 protein and the lack of TOP1 enzyme appeared implicated in the cytotoxic activities of the series of bisdioxopiperazine ICRF compounds tested. This functional assay in a living organism therefore appears to provide a valuable tool for probing distinctive and specific mode(s) of action of diverse anticancer agents. \u00a9 1999 Cancer Research CampaignA screening procedure which permits identification of compounds based on their activities against specific biological targets directly in a living organism,"} +{"text": "The uptake, retention and effects of aluminium chloro sulphonated phthalocyanine (AlSPc) were measured in two cell lines, UV-2237 a murine fibrosarcoma and the non-tumorigenic NIH/3T3 fibroblast line. The behaviour of cells treated with AlSPc was compared with that of those treated with haematoporphyrin derivative (HpD), a photosensitizer often used in photodynamic therapy (PDT) of cancer. AlSPc absorbs light strongly in the red region, is taken up by cells in a dose dependent fashion and is retained in vitro over a period of days (5 days after exposure greater than 40% remains cell-associated versus less than 25% of HpD). Additionally AlSPc was less cytotoxic to cells, maintained in darkness or exposed to room light, compared to HpD (100% viability versus 0% viability 3 days after 60 min exposure to room light). However red light (approximately 600-700 nm) caused greater toxicity in AlSPc-treated cells (100%) than in similarly exposed HpD-treated cells (less than 60%). No significant differences were detected between the responses of the fibrosarcoma and the fibroblast cell lines. These characteristics of AlSPc suggest that it may prove to be a useful photosensitizer for PDT of cancer and this possibility is discussed."} +{"text": "This investigation first set out to analyse which cellular proliferative and apoptotic factors, in addition to the clinical prognostic factors, are most predictive in patients with non-small-cell lung carcinomas (NSCLC). To this purpose, we related the proliferative factors proliferating cell nuclear antigen (PCNA), cyclin A, cyclin D1, cyclin-dependent kinase 2 (cdk2), cdk4 and the proportion of cell cycle phases in NSCLC to the survival times of 150 patients. Additionally, we associated the expressions of Fas, Fas ligand and caspase-3 in NSCLC to patient survival. Immunohistochemistry was used to determine the proteins and flow cytometry to assess the proportion of cell cycle phases. Patients with PCNA-positive carcinomas had significantly shorter survival times than patients with PCNA-negative carcinomas . Corresponding results were obtained with the factor cyclin A (64 vs 92 weeks), with the factor cdk2 (76 vs 89 weeks), with the factor cdk4 (62 vs 102 weeks) and with the proportion of S phases (86 vs 121 weeks). Patients with an expression of the apoptotic factors had a more favourable prognosis than patients with negative carcinomas. The median survival times of cancer patients with Fas expression was 86 weeks and of those without Fas expression only 69 weeks. Corresponding results were obtained with the Fas ligand (87 vs 41 weeks) and caspase 3 (87 vs 34 weeks). In order to determine whether a combination of factors can yield improved prognostic information, we investigated all possible combinations of the proliferative and apoptotic factors. Patients with tumours having a high proliferative activity, but which did not express apoptotic factors had the shortest survival times while patients with a low proliferative activity and a high expression of apoptotic factors had the most favourable outcome. A multivariate analysis (Cox model) of the cellular and clinical prognostic factors indicated that stage, lymph node involvement, Fas, PCNA and cyclin A are the most important prognostic factors for the clinical outcome of patients with non-small-cell lung carcinomas. \u00a9 2000 Cancer Research Campaign"} +{"text": "Epidemiological evidence has implicated Chinese salted fish as a human nasopharyngeal carcinogen.

We used fluorescence in situ hybridisation (FISH) with centromere-specific probes for chromosomes 7, 8, 17, X and Y to establish the distribution of centromere copy numbers in frozen-stored or freshly prepared samples of benign prostate hypertrophy (BPH) and to detect numerical aberrations of these chromosomes in 28 prostate cancers from Japanese men. There was no significant difference in the data of centromere copy numbers between fresh and frozen-stored tissue. The most common aberration in prostate cancers was a gain of chromosome 8 (57%), with numerical aberration of chromosome 7 being the second most frequent anomaly (50%). Numerical aberration of chromosome 7 is most significantly associated with a higher Gleason score (GS) (P < 0.005) or with lymph node metastasis (P < 0.001). Numerical aberration of several chromosomes, including chromosomes 7 and/or 8, was common in aggressive prostate cancers. Loss of chromosome Y was detected in only 4% of cases. FISH analysis thus proved to be a useful method for detecting numerical aberrations of individual chromosomes, with application to touch preparations of frozen-stored tissue having the advantage of exact sampling of cancer foci. The results suggest that numerical aberration of chromosome 7 is associated with aggressive tumour behaviour and poor prognosis of patients with prostate cancer.

Management of complicated wounds after tumor extipiration of pelvic and proximal lower limb musculoskeletal sarcoma represents an essential component in the outcome of these patients. The authors present modified vertical rectus abdominis musculocutaneous (VRAM) flap techniques to reconstruct extensive defects after debridment of these complicated wounds. Material and Methods. Over a period of 4 years (2002\u20132005), 5 men and 2 women were managed. Median age was 21 years (range 15\u201349). The patients were managed for complicated lower trunk, groin, and upper thigh wounds after resection of three pelvic chondrosarcomas as well as two pelvic and two proximal femur osteosarcomas. The modifications included a VRAM flap with lateral and tongue-like extension design of the skin paddle (5 cases) or a delayed extended VRAM flap (2 cases). Results. All flaps showed complete survival and healing with no ischemic events providing stable coverage. All patients were ambulant with good limb functions in terms of walking and gait after adequate rehabilitation, 2 needed support with crutches. Conclusion. The modified VRAM flaps offer reliable reconstructive tools for coverage of complex groin and thigh defects by providing larger well-vascularized soft tissue with acceptable donor site. Limb salvage remains a major objective in contemporary management ofbony and soft tissue sarcomas of the pelvis and lower extremities , 2. RadiSeven consecutive patients with complicated wounds secondary to resection of pelvicand proximal lower extremity musculoskeletal sarcoma were managed with modified VRAM flaps between2002\u20132005. The medianage of the patients in this series at the time of surgery was 21 years (range15\u201349) and included 5 men and 2 women. The modifications included VRAM flapwith lateral and tongue-like extension design of the skin paddle (5 cases) or adelayed extended VRAM flap (2 cases). All the patients have been treated with amultidisciplinary approach; the management of osteosarcoma patients included a 4-month course of neoadjavant chemotherapyfollowed by resection of the primary tumor and postoperative 3-month course of chemotherapy;while chondrosarcoma patients (3 pelvic) were offered surgical resection only.The complications, which necessitated management by the plastic andreconstructive surgeons, included infection and wound dehiscence with ultimateexposure of metal prosthesis (4 patients) and necrosis of thigh flaps (3patients). The median interval duration between the primary operation and thereconstructive procedure for the complicated wounds was 16 days (range: 13\u201336).All patients underwent thorough clinical assessment, adequate debridment andirrigation of the wounds, followed by immediate coverage of the resultantdefects (median size 7 \u00d7 17\u2009cm) usingmodified VRAM flaps.This technique was used to cover exposed metal plates dueto wound breakdown after osteosarcomas resection of proximal femur where lengthof the flap was predominantly required than its width. An ipsilateralparasternal skin paddle was designed 10\u2009cm cephalic to the costal margin and 2\u2009cm from the lateral sternal edge. The pinch test, originally described byTaylor et al. , was useThis technique was used in cases after resection ofchondrosarcomas and osteosarcomas of the pelvis, which necessitated thedevelopment of large subcutaneous thigh flap to allow adequate exposure andvascular exploration to achieve adequate oncological resection. Extensive full-thicknessthigh flap necrosis occurred in these patients which necessitated adequatedebridement and coverage of the resultant defect utilizing a contralateral,laterally oriented VRAM with a tongue-like skin extension. The contralateralmuscle was selected due to the sacrifice of the ipsilateral inferior epigastricpedicle as part of the radicality of the primary tumor resection. The lateralorientation of the skin paddle was designed to be oblique (45\u00b0) tothe longitudinal axis of the rectus muscle to provide an average extra lengthof 5\u2009cm. The tongue-like extension ofthe skin paddle was designed throughout the whole length of the muscle taperingtowards the pivot point of the flap at the entry of the inferior epigastricpedicle. The fasciomusculocutaneous component of the VRAM flap was harvestedutilizing the standard technique with elevation of the laterally oriented partof the flap in the fascial plane. Theorigin and insertion of rectus muscle were transacted leaving the vascular pedicle asthe sole tether point; this significantly increased the arc of rotationallowing more muscle mass to be transposed to the wound. Incising the skinbridge between the donor and recipient defect to lay open the tunnel connectingthe recipient and the donor site followed this. The tongue-like skin extension provided the roof foropened tunnel after rotation of the flap to settle to the defect; allowing moreroom for the pedicle and providing coverage for the medial part of the defect.In all patients, the donor site was closed primarilyafter reinforcement of the abdominal wall using an onlay prolene mesh, suctiondrains were used both at the recipient and donor sites. All patients weremobilized within 2 weeks postoperatively under supervision of the orthopaedicand physical therapy team. The mean duration to postoperative chemotherapy was3 weeks. The mean follow-up period was 26 months at which patients were followed up with assessment of the oncological outcome, durability of soft tissue reconstruction, and finally assessing the functional outcome using Enneking system,All flaps showed complete survival and healing withno ischemic events, hence providing stable coverage. Mild infection wasobserved in 1 patient; no haematomas were detected. All patients were ambulantwith good limb functions in terms of walking and gait after adequaterehabilitation; 2 needed additional support with crutches. All patients showedgood emotional acceptance; and no pain has been observed during ambulation inall patients. One patient developed incisional hernia at the donor site that requiredrepair 1 year later; otherwise, no other donor site morbidity was noted.Another patient died of haematogenous metastatic spread after completeresection 15 months later. There was no hypertrophic scar formation or flapbreakdown experienced on long-term follow-up in any of the patients.Limb preservation has become a more realistic andnecessary goal in the management of patients with musculoskeletal sarcoma ofextremities . RadiatiThe reconstructive options to provide coveragefollowing debridment of these complicated wounds would be local, distant flaps,or free-tissue transfer. VRAM flaps havebeen used successfully in coverage of defects of the chest wall, groin, hip,perineal, vaginal, and gluteal regions with good functional outcomes \u201317. The The delayed phenomenon has been used for many yearsto enhance functional blood flow through vasodilatation of the arterial networkand avoidance of complete vasoconstriction caused by catecholamine release, andhence it increases the flap reliability especially in high-risk patients , 24. TheThe authors believe that these modifications willprovide reliable extralength of soft tissue, which is tension free with a widerarc of rotation, better filling of dead space with well-vascularized tissue soas to resist infection, and stable coverage with good functional outcome.Other modalities described for management ofcomplicated infected wounds as skin grafting or vacuum-assisted closure wouldnot be suitable due to the presence of dead space and exposed hardwareprosthesis after debridement , 4, 27. The use of free-tissue transfer is rare in theseclinical scenarios; on the other, hand-free osteocutaneous fibular flaps wereperformed for primary skeletal reconstruction after tumor extipiration ofsarcoma of the lower extremities rather tIn conclusion, the modified VRAM flaps would offerreliable reconstructive tools for coverage of complicated primary wound withnecrosis and breakdown after radical resection of pelvic and proximal lowerlimb musculoskeletal sarcoma. They offer larger well-vascularized soft tissuewith acceptable donor site, more durable coverage with no delay in thepostoperative adjuvant therapy, good functional outcome, together with overallimprovement in the survival."} +{"text": "A method was developed for delineating the structure ofparamagnetic metal complexes.

Experiments using lactate dehydrogenase (LDH)-deficient ras-transfected Chinese hamster ovarian cells have been undertaken to address directly the hypothesis that lactic acid production is responsible for tumour acidification. The variant cells produce negligible quantities of lactic acid and consume minimal amounts of glucose compared with parental cells. Lactate-producing parental cells acidified lightly-buffered medium but variant cells did not. Tumours derived from parental and variant cells implanted into nude mice were found to have mean values of extracellular pH (pHe) of 7.03 +/- 0.03 and 7.03 +/- 0.05, respectively, both of which were significantly lower than that of normal muscle . Lactic acid concentration in variant tumours (450 +/- 90 microg g(-1) wet weight) was much lower than that in parental tumours (1880 +/- 140 microg/g(-1)) and similar to that in serum (400 +/- 35 microg/g(-1)). These data show discordance between mean levels of pHe and lactate content in tumours; the results support those of Newell et al (1993) and suggest that the production of lactic acid via glycolysis causes acidification of culture medium, but is not the only mechanism, and is probably not the major mechanism responsible for the development of an acidic environment within solid tumours."} +{"text": "Automated Flow Injection Gas Diffusion (FIGD) promotes theselective transmembrane diffusion of MAs and NH3 from aqueoussample under strongly alkaline , chelated (EDTA) conditions into a recycled acidic acceptor stream.

The in vivo BUDR method requires that a single tumour sample be taken 4-6 h after infusion and that bivariate flow cytometry (FCM) be employed to measure simultaneously the percentage of BUDR-labelled cells and their mean DNA content (following propidium iodide staining). This technique rapidly furnishes the labelling index (LI) and the DNA synthesis time (TS), from which the tumour potential doubling time (Tpot) and production rate are calculated. The procedure took 6-9 h to complete and there was no immediate toxicity from BUDR administration. Successful LI and TS determinations were obtained in 89 (80%) and 80 (72%) of the 112 patients, respectively. Correlations were sought between kinetic parameters and a number of pathological and clinical ones. In 34 patients with acute non-lymphoblastic leukaemias who were uniformly treated for remission (CR) induction and maintenance, proliferative activity, as measured by Tpot and FTR, was greater in responsive than in non-responsive patients, and in those who experienced CR for over 8 months than in those who had a shorter CR. Proliferative activity was also greater in patients with advanced gastric cancers than in those with more limited disease. No correlations between kinetic and clinical and pathological parameters were found in gliomas. These data indicate the in vivo BUDR infusion coupled with FCM measurements can be performed in clinical settings to obtain kinetic data rapidly in quite large patient series.

Livers from age-matched control rats were also examined. From the 20 month ciprofibrate group, nine neoplastic nodules (NNs), 27 HCCs and four non-tumorous surrounding tissue controls (NTCs) were examined. Significant DNA tetraploid populations were seen in both the NNs and NTCs. A significant increase in the percentage of DNA diploid cells was observed in the NN samples. No significant difference in the percentage S-phase cells was seen. Emergence of cell populations with new DNA ploidy classes (8c or DNA aneuploid) as compared with NTCs was only seen in HCCs (7 of 27), and five of these seven were DNA aneuploid, as distinct from DNA tetraploid, populations. A total of 16 of 24 HCC samples that were adequate for cell cycle analysis had average percent S-phase greater than the mean of the NTCs plus three standard deviations. Although a direct role cannot be inferred, these results support the hypothesis that increases in the fraction of diploid cells is an important early event in the development of rat HCC and that further alterations in DNA ploidy and increased proliferative fraction accompany the development of HCC."} +{"text": "Copper(II) complexes of several hydroxyflavones were prepared and characterised through their physico-chemical properties.

Effects on tumour growth were correlated with arterial collateral development in this system. Three treatment methods were compared: (1) the left hepatic artery was ligated at the liver hilum (ligation group); (2) TNP-470 (40 mg per body) was infused continuously for 7 days via the common hepatic artery (TNP group); (3) the left hepatic artery was ligated and TNP-470 was infused continuously for 7 days via the common hepatic artery (ligation + TNP group). These treatments were started 12-14 days after tumour inoculation. The day of initiating treatment was defined as day 0. Although there were no significant differences in tumour volume among the three treated groups on day 7 after treatment, tumour volumes in the ligation + TNP group were significantly smaller than in the ligation group and the TNP group on day 14 after treatment. The vasculature and arterial collaterals around the tumour were demonstrated by the perfusion of a silicon rubber solution, Microfil. In the ligation + TNP group, the new microvasculature around the tumour decreased compared with the ligation group. The TNP-470 inhibition of microvascular proliferation may limit the development of collaterals that communicate with new feeding arteries. These results suggest that transarterial embolization combined with TNP-470 may enhance the anti-tumour effect of transarterial embolization alone in the treatment of liver tumours."} +{"text": "The hormonal mechanisms involved in the development of gynaecomastia accompanying the treatment of multiple myeloma in adult men have been investigated by studying levels of circulating testosterone (T), oestrone (EI), oestradiol (E2), sex-hormone binding globulin (SHBG), prolactin (PRL) and the gonadotrophins LH and FSH, before, during and after development of gynaecomastia in 4 men. These have been compared with 5 closely matched men who did not develop gynaecomastia during similar treatment for myeloma. Levels of circulating T fell, and levels of E1 and E2 rose during treatment periods in all subjects, and the changes were statistically significant in subjects developing gynaecomastia, which resolved as levels of sex steroid returned towards normal following cessation of treatment. We conclude that treatment of adult men for myeloma results in testicular dysfunction with a reduction in circulating T and a rise in circulating oestrogens. These changes are most marked in subjects developing gynaecomastia in whom the normal breast tissue is stimulated by a subtle, transient oestrogen:androgen imbalance in favour of oestrogens."} +{"text": "Twenty-four symptomatic patients with advanced non-small cell lung cancer (NSCLC) were treated with cisplatin-based chemotherapy . Patients were assessed for symptom relief as well as for objective response. Although only five patients achieved an objective response (21%), 18 patients (75%) reported a complete disappearance or good improvement in at least one of their tumour-related symptoms. The overall symptomatic response rate was 67% with 16 patients feeling better or much better on treatment. The toxicity of treatment (primarily myelosuppression and nausea and vomiting) was mild and hair loss was minimal. The high incidence of symptomatic relief seen in this study, even in the absence of objective response, suggests that moderate dose chemotherapy may have a role in the palliation of NSCLC."} +{"text": "Activation of the RET tyrosine kinase domain occurs in a proportion of thyroid papillary carcinomas. Three chromosomal rearrangements have been described, of which PTC1 is the commonest. Wide differences (2.5-25%) in frequency of PTC1 in different populations have been reported; it is not clear whether these are due to environmental factors, racial differences or technical reasons. We have developed a simple and rapid reverse transcriptase nested polymerase chain reaction (RT-nPCR) method enabling the detection of gene expression from single 5 microns sections of formalin-fixed paraffin wax-embedded archival material. We have applied this approach to detect expression of the RET tyrosine kinase domain, allowing identification of RET activation resulting from any rearrangement, whether characterised or not, or from overexpression. A retrospective study was performed on 22 adult and 21 childhood papillary carcinomas. Thirteen of 22 (59%) adult and 10 of 21 (48%) childhood carcinomas showed evidence of RET activation, demonstrating a major role for the RET oncogene in UK thyroid papillary carcinogenesis. This study also shows a similar frequency of RET activation in both children and adults. The use of a technique that allows reliable amplification of RNA from archival material, using primers chosen in different exons so that amplified products are readily distinguished from genomic DNA, will allow correlation of translocations and chromosomal rearrangements with a variety of specific tumour types."} +{"text": "A lymphocyte stimulation assay is described which detects immune reactivity to antigens derived from the CaSki cervical carcinoma cell line.

Phylogenetic analysis confirms that the PPRV strain from Tibet is classified as lineage 4 and is closely related to viruses currently circulating in neighboring countries of southern Asia. Peste des petits ruminants (PPR) is an acute and highly contagious viral disease contracted by small ruminants such as goats and sheep and causing high rates of illness and death. The disease is endemic in parts of sub-Saharan Africa, the Middle East, and Asia. The PPR virus (PPRV) genogroup consists of 4 lineages in the Ngari region, where animals having clinical signs of PPRV infection had been reported by local authorities. The second group included 298 animals in Gar and Bulang counties in the same region and in 2 counties bordering the Ngari region (Nyima in Nagqu region and Zhongba in Shigatse region). The third group contained 520 animals in 5 counties within 3 separate regions . We examined 1,536 animals (771 goats and 765 sheep) and collected serum samples from each. A competitive ELISA that used a monoclonal antibody to the N protein . Rates oField samples, including organ and swab specimens, were obtained from 49 goats and sheep suspected of being infected with PPRV. These animals inhabited 4 counties in the Ngari region . Two reverse transcription\u2013PCRs (RT-PCR) and 1 newly developed and validated real-time quantitative RT-PCR (qRT-PCR) were conducted to determine whether the animals had viral RNA .The study confirmed 11 outbreaks in 4 counties in the southwest Ngari region in Tibet. Nine of the 11 occurred in southern Rutog County, northern Ge\u2019gyai County, and Gerze County, and samples from these 9 were seropositive for PPRV , panel AThe nucleic acid sequences obtained from the PCR products were aligned with sequences from PPRV strains available in GenBank. Partial sequencing (448 bp) of the F gene showed that 20 of 21 samples were identical over the portion of the genome that was characterized (GenBank accession no. EU816772). One (GenBank accession no. EU815053) differed from other Ngari sequences by 1 nt. The Ngari sequences showed a level of nucleotide identity with other PPRV strains of 88.8%\u201398.8%. Strains of PPRV from Tibet were classified as lineage 4 and were closely related to the India/Bsk/Guj/05 strain isolated in India in 2005 , panel AIn this study, PPRV was found by collecting samples from animals in the field and detecting infection by using competitive ELISA and RT-PCR. Our research provides valuable data on PPRV infection in small ruminants in Tibet. Infection was observed in 4 counties in the Ngari region of southwestern Tibet. Most outbreaks occurred in Rutog and Ge\u2019gyai counties; 1 outbreak was confirmed in Gerze County and another in Zada County. Epidemiologic and serologic evidence suggests that the infection first emerged in Rejiao village in southwestern Rutog from November 2005 through March 2006. PPR likely existed for several years without being recognized in Tibet because veterinarians, animal health workers, and livestock owners in the area are unfamiliar with its clinical and pathologic features. Also, this disease is frequently confused with other diseases that cause respiratory problems and death in small ruminants (The molecular epidemiologic techniques provided data suggesting cross-border transmission of PPRV infection into Tibet.

Colony forming efficiency was low in 6-week or older rats but was markedly increased by 1000-1500 rad local thoracic irradiation (LTI) given 7-14 days before the tumour cell injection, or by antilymphocytic serum (ALS) but not by sublethal whole body irradiation (WBI). Similarly, LTI increased the incidence of pulmonary metastases produced by a solid tumour growing in the leg muscle. Stimulation of CFE by LTI was a strictly local phenomenon and not due to effects of irradiation on thymus, spleen or other tissues of the rat. LTI failed to increase CFE in immunized rats. It is concluded that (1) LTI stimulates clonogenic growth of tumour cells arrested in the lungs, by causing inflammatory reactions accompanied by regenerative cellular proliferation of lung tissue, which increases the \u201cplating\u201d efficiency of tumour cells, (2) the increase in CFE in lungs is not due to suppression of immunity to tumour growth by LTI."} +{"text": "The full spectrum technique in the fourier domain was studied forsimultaneous determination of Cu(II), Pb(II) and Cd(II) with 4-(2-pyridylazo) resorcinol (PAR).

Poor knowledge and awareness about childhood autism, especially among health workers can compromise early recognition and interventions which had been known to improve prognosis in children with autism. In formulating policy and designing interventions for these children, there is need to develop a reliable tool that can be used in assessing baseline knowledge about childhood autism among health workers and the impact that future continued education and awareness campaign may have on such baseline knowledge. Knowledge about childhood autism among health workers (KCAHW) questionnaire was designed for this purpose.The KCAHW questionnaire is a nineteen (19) item self-administered questionnaire that is divided into four domains. KCAHW questionnaires were distributed to fifty (50) psychiatric nurses involved in community mental health services in South-Eastern Nigeria to complete. After two weeks period, the KCAHW questionnaires were re-administered to the same fifty (50) psychiatric nurses to assess their knowledge about childhood autism and to assess the test-retest reliability and internal consistency of this questionnaire.KCAHW questionnaire showed good test-retest reliability when the mean domain and total scores at first and second time administration were compared. The four mean domain scores and the mean total scores at first and second time administration were significantly correlated. The questionnaire also had a good overall internal consistency when the mean scores of the four domains were correlated with mean total scores .The KCAHW questionnaire is a reliable tool for assessing knowledge of health workers about childhood autism. It would be a useful tool in improving early recognition of features of autism among affected children in Sub-Saharan African and other developing countries of the world where knowledge and awareness about childhood autism is low. Since Leo Kanner's paper titled, \"Autistic disturbances of affective contact\" about seven decades ago , awareneEarlier survey on knowledge about childhood autism among health care workers had been by Stone . The stuRhoades et al exploredThe above surveys coming from the United States of America (USA), an environment where knowledge and research about childhood autism are more widely spread than what obtains in sub-Saharan Africa point to the need to assess knowledge and awareness in this environment and put in place programs to increase such knowledge and awareness with the ultimate aim of helping children with ASD.It had been presumed that in view of the rarity of presentation of childhood autism cases in pediatric health facilities in developing countries especially Sub-Saharan Africa, health care workers especially the nurses who are often in charge of various Primary Health Care (PHC) facilities in rural communities in Africa might not be well versed with the condition. Subsequently, early identification at the community level and intervention which have been shown to improve the prognosis of these cases ,21,22 maThis presumption was put into test in May 2007, when African Network for the Prevention and Protection Against Child Abuse and Neglect (ANPPCAN), Nigeria Chapter in collaboration with the World Bank carried out a survey to ascertain the level of knowledge and awareness of health care workers and the general public in Enugu State, South Eastern Nigeria on autism and implemented a project aimed at increasing the level of awareness on autism.The results of the survey showed that there is a very low level of awareness on autism among the general public and a low to average level of awareness among various categories of health care workers, with highest level of awareness noted among those health workers working in psychiatric facilities. Attempt was made then, to increase the level of awareness on autism through a workshop organized for the stakeholders and a radio phone \u2013 in program for the general public. However, one of the problems encountered during the survey was the unavailability of easily understandable and reliable questionnaire for measurement of the health care workers baseline knowledge of autism, aimed at early identification of cases in the community . The KCAIt had therefore been established that knowledge and awareness on autism and ASD is low in south-eastern Nigeria and there had been recent outcry in Nigeria to promote knowledge and awareness about childhood autism among the health care workers and the general community .In doing this, there is need for baseline assessment of present knowledge, facilities in place for intervention among other things. This would ensure proper planning. Promoting awareness at the community level should begin with various health workers who are involved in community health services. They can be trained to become trainers of other category of people in the community towards early recognition of children with childhood autism.For proper design of community campaign and continued education needed for these health workers, the need arises to design a reliable tool that can be used in measuring their baseline knowledge about childhood autism and the possible impact that future continued education and campaign may have on the knowledge of these health workers about childhood autism.Knowledge and awareness about childhood autism may vary from one geographical region to another. The same tool can be used to assess variation in knowledge of the disease condition over different geographical regions, given an index of geographical locations where immediate attention need to be focused as regards health workers and community education.\"Knowledge about Childhood Autism among Health Workers (KCAHW) Questionnaire\" for use in various communities of developing countries where knowledge about childhood autism is limited among the health workers working at the community level.The above reasons inform the design of This article is aimed at describing the content of KCAHW questionnaire and reporting the test-retest reliability and internal consistency of the questionnaire.Location of the study was at Federal Neuro-Psychiatric Hospital, New Haven, Enugu (FNHE), Nigeria. FNHE is a specialist Psychiatric Hospital located in the South-Eastern region of Nigeria. The hospital is involved in community mental health service collaboration with various PHC facilities located in the rural communities of South-Eastern Nigeria. This community mental health care service in various PHC facilities in this region of the country is overseeing by the psychiatric nurses employed by the hospital.Ethical approval for this study was obtained from the ethical committee of FNHE, Nigeria.A total of fifty (50) psychiatric nurses employed by FNHE, Nigeria and who are involved in the community mental health services of the hospital participated in the study. There were 12 males and 38 females. The fifty nurses included in the study had had a minimum of five years of practice in general psychiatry nursing and possessed diploma qualification in general nursing and psychiatry nursing. It should be noted that only psychiatric nurses were used as the sample for this study because in the context of our environment in Nigeria and other sub-Saharan African countries, they are supposed to be the most likely health care workers who attend to cases such as autism and ASD and still supervise health care services at primary care level.In addition to the socio-demographic questionnaire, KCAHW questionnaire was distributed to consented fifty (50) psychiatric nurses to complete. After a period of two (2) weeks, the KCAHW questionnaire was re-distributed to the same fifty (50) psychiatric nurses to complete. The questionnaires were completed by the respondents and collected from them there and then at each point of administration to prevent them from consulting any study material or discussing with their colleagues before filling in their responses.This is a self administered questionnaire that contained a total of nineteen (19) \u2013 item questions. Each of the item questions has three (3) options to choose from with only one of these three options being correct. The correct option on each item question attracts a score of one (1), while the other two options that are incorrect attract a score of zero (0) each.The KCAHW questionnaire is further divided into four (4) domains:Contained eight (8) item questions that addressed the impairments in social interaction usually found in children with childhood autism. A maximum and minimum score of 8 and 0 respectively are possible in this domain.Contained only one (1) item question that addressed impairment in area of communication and language development, which is part of symptom presentation in children with childhood autism. A maximum and minimum score of 1 and 0 respectively are possible in this domain.Contained four (4) item questions that addressed area of obsession and compulsive pattern of behavior found in children with childhood autism, a pattern of behavior which had been described as restricted, repetitive and stereotyped. A maximum and minimum score of four (4) and zero (0) respectively are possible in this domain.Contained six (6) item questions that addressed information on what type of disorder is childhood autism, possible co-morbid conditions and onset of childhood autism in affected children. A maximum and minimum score of six (6) and zero (0) respectively are possible in this domain.Therefore, a maximum and minimum total score of nineteen (19) and zero (0) respectively are possible when the four domain scores are added together.The content of the questionnaire and the scoring system are shown in Appendices 1 and 2.The mean total score on KCAHW questionnaire among a particular sample population or community is a measure of level of knowledge about childhood autism among that particular sample population or community.The mean scores in each domain and the mean total scores generated when KCAHW questionnaires were administered the first and second time were compared with paired t-test statistical analysis to assess the test-retest reliability of the KCAHW questionnaire.Then, the mean inter-domain scores during the first and second time administration of the questionnaire were correlated with the mean total scores and cronbach's alpha was calcA total of fifty (50) psychiatric nurses employed by FNHE, Nigeria and who are involved in the community mental health services of the hospital participated in the study. There were 12 males and 38 females with mean age of 32.6 years. The mean scores in the four domains of KCAHW questionnaire and mean total scores of 9.6 and 9.8 on first and second time administration of KCAHW questionnaire respectively which gave indices of level of knowledge on childhood autism in that particular sample population are shown in Table The paired t-test analysis comparing these mean scores and the 95% Confidence Interval (95% C.I) for the differences in the mean scores are shown in Table The correlation co-efficient for the four mean domain scores and mean total scores at first and second time administration of KCAHW questionnaire are shown in Table The internal consistency of KCAHW questionnaire was assessed by correlating different mean domain scores with the mean total scores at first and second time administration of the questionnaire and calculating the cronbach's alpha. The cronbach's alpha value of 0.97 obtained following the correlation is acceptable based on Nunnaly's recommendation .The ten by ten correlation matrix table of the four mean domain scores and mean total scores at first and second time administration of the KCAHW questionnaire is shown in Table The content of KCAHW questionnaire had been described. The test-retest reliability of the questionnaire is good based on the significant correlations in the mean domain and mean total scores at first and second time of administration. The KCAHW questionnaire also showed a good internal consistency as revealed in the cronbach's alpha value obtained for mean domain scores correlation with the mean total scores both at first and second time of administration.The imperative need to increase the level of knowledge and awareness among health workers and of the general community in Sub-Saharan African and other developing countries of the world about childhood autism necessitated the design of a reliable measuring tool that can be used to assess baseline knowledge of health workers on childhood autism and also subsequently the impact the future campaign and continuous education may have on the knowledge of these health workers about childhood autism, especially those group of health workers at primary health care facilities who are closer to the communities.KCAHW questionnaire could also be used to compare knowledge about childhood autism among different categories of health workers, if there is an indication for such. The variation in knowledge about childhood autism among health workers that could exist in various geographical regions of Sub-Saharan African and other developing countries where awareness about autism and ASD is low could also be assessed with KCAHW questionnaire.The limitation of administering the KCAHW questionnaire is that it could only be completed and collected immediately from the respondents upon administration. This is to prevent consultation of study materials or discussion with colleagues which can influence the respondents' response to the questions contained in the questionnaire. The KCAHW questionnaire would therefore serve the purpose only of a point time assessment of knowledge.KCAHW questionnaire is a reliable tool for assessing knowledge of health workers about childhood autism, aimed at early recognition of the condition in the primary care settings. It would be a valuable tool in assessing baseline knowledge of health workers about childhood autism in Sub-Saharan African communities and other developing countries where public awareness about childhood autism is low and policy and interventions are being planned for children affected by childhood autism. The level of knowledge of health workers about childhood autism, especially those working in the rural communities in this environment and other developing countries is an essential ingredient for early recognition and intervention which had been noted to improve prognosis in the affected children ,17,18.

Circulation of these strains in the UK was accompanied by an unusually high number of laboratory confirmed influenza associated fatalities in children. This study was carried out to better understand risk factors associated with fatal cases of influenza in children.Case histories, autopsy reports and death registration certificates for seventeen fatal cases of laboratory confirmed influenza in children were analyzed. None had a recognized pre-existing risk factor for severe influenza and none had been vaccinated. Three cases had evidence of significant bacterial co-infection. Influenza strains recovered from fatal cases were antigenically similar to those circulating in the community. A comparison of protective antibody titres in age stratified cohort sera taken before and after winter 2003\u201304 showed that young children had the highest attack rate during this season . Clinical incidences of influenza-like illness (ILI) in young age groups were shown to be highest only in the years when novel antigenic drift variants emerged.This work presents a rare insight into fatal influenza H3N2 in healthy children. It confirms that circulating seasonal influenza A H3N2 strains can cause severe disease and death in children in the apparent absence of associated bacterial infection or predisposing risk factors. This adds to the body of evidence demonstrating the burden of severe illness due to seasonal influenza A in childhood. Influenza A virus is a cause of severe morbidity and mortality worldwide Human seasonal influenza A viruses evolve rapidly through genetic mutation, allowing them to escape previously acquired immunity This study investigated fatal cases of influenza H3N2 in children during the emergence of A/Fujian/411/02 in the UK in winter 2003\u201304. The goals of the study were: to investigate whether any of the case fatalities had underlying disease or risk factors; to evaluate how laboratory confirmed infections were recorded in death certification; to describe the clinical and pathological findings in relation to circulating virus strains; and to investigate whether the high number of laboratory confirmed fatalities was reflected in measures of morbidity in primary care, age specific attack rates and age specific all-cause mortality. We reviewed the antecedent illness history, underlying risk factors, clinical findings and observed pathology at autopsy. Age-stratified serological data were combined with community based clinical morbidity data to provide an assessment of the overall population immune susceptibility, attack rates and impact of A/Fujian/411/02-like influenza in comparison with other winter seasons in which new H3N2 antigenic variants emerged.This study was conducted as part of a public health inquiry by the Health Protection Agency and Health Protection Scotland into paediatric deaths, where it was agreed that ethical approval for linking personal clinical outcome information to virus strains was not required.

Microbiological findings deemed significant are included.A case was defined as a death in child less than eighteen years of age during the 2003\u201304 influenza season . The activity took place within the context of a national public health enquiry into influenza associated childhood deaths in winter 2003. Children without risk factors recognized by UK Joint Committee on Vaccination and Immunisation to increase the risk of influenza related complications were classified as \u201cpreviously healthy\u201d. U.K. risk factors for severe influenza from 2003\u201304 are given in reference 12. Verification of the certified cause of death in each fatal case was performed by matching cases to Office of National Statistics (ONS) death registration records held at HPA.http://www.hpa.nhs.uk/web/HPAweb&HPAwebStandard/HPAweb_C/1195733836222.The Weekly Returns Service (WRS) of the Royal College of General Practitioners is a clinical information system based upon a network of sentinel general practices located throughout England and Wales Viruses were grown in either MDCK or MDCK-SIAT1 cells and subtyping was performed by RT-PCR, if no virus isolate was available Nationally representative, anonymised, age stratified residual sera were obtained with ethical approval from the HPA serum bank held in Preston NHS hospital. The number of sera tested from 2003 was 88 (ages 0\u20134), 196 (ages 5\u201317), 293 (ages 18\u201344), 185 (ages 45\u201364) and 101 (ages 65+). The number of sera from 2004 for each age group was 70 (ages 0\u20134), 160 (ages 5\u201317), 273 (ages 18\u201344), 199 (ages 45\u201364) and 98 (ages 65+).Haemagglutination inhibition (HI) assays to assess protective antibody titres in human sera were performed using standard protocols and antigenically representative viruses. A titre of >1/40 was taken as protective.Seventeen fatal cases of laboratory-confirmed influenza A in children under eighteen years were reported to HPA between September and December 2003. This period corresponded with peak circulation of influenza during the winter 2003\u201304. The median age of fatal cases was two years, with a range from four months to seventeen years; the majority (64%) were under five years. Ten (58%) deaths were in females. The duration of illness prior to death varied, with a median duration of three days (range 0\u201314 days). Four (24%) deaths were sudden with either no recognized antecedent illness or illness of less than 6 hours duration. A further four (24%) occurred within forty-eight hours of onset of symptoms, five (29%) were ill for three to four days prior to death, three (18%) were ill for a week prior to death, and one individual was unwell for over ten days. Eight (47%) children died following hospitalization and nine (53%) died in the community. In the cases with recognized antecedent illness, eight (57%) had fever, eleven (79%) had respiratory symptoms (cough/chest infection/croup), three (21%) had vomiting and/or diarrhea, two (14%) had clinically recognized sepsis. Two (14%) children were markedly confused prior to collapse .Among the sixteen cases for whom underlying health status information was available none was recorded as having a known risk factor for severe influenza, although two cases (both over two years) had a history of febrile convulsions In nine cases (53%) influenza A detection occurred by more than one method , either in respiratory clinical samples or from post-mortem tissues. In eleven (64%) cases influenza A virus isolates were recovered. The cultured viruses were analyzed for their antigenic characteristics; all isolates were found to be antigenically similar to each other and to virus isolates recovered from non-fatal cases matched for age, week of infection and geographical location (controls) as well as to other circulating strains from the same locality (data not shown). Influenza AH3N2 was detected by RT-PCR only in five (29%) cases.Staphylococcus aureus and Streptococcus pneumoniae in blood were identified in the two cases of clinical sepsis and one case had Streptococcus pneumonia bacterial pneumonia. No other significant bacteriological findings were described. Enterovirus and norovirus were also detected by RT-PCR in two cases.Staphylococcus aureus or Streptococcus pneumoniae and myocarditis in two cases (12%). Eight cases (47%) showed abnormalities of the lymphoid system, including seven (41%) with enlargement of the lymph nodes (LN), thymus or spleen, six (35%) with hemorrhagic LN, thymus or spleen and two (12%) with \u201cstarry sky\u201d LN indicating an infiltration of macrophages in the lymphoid tissue. No metabolic disorders were recognized ante or post mortem, although one case showed unusual large fiber laryngeal musculature of uncertain significance.Autopsy reports were available for all cases . All casDeath registration information was not available for one case. By routine death registration only nine of sixteen fatal cases (56%) were coded with influenza (ICD10 J10\u2013J11). Seven of these specifically mentioned influenza A on the death certificate and a further certificate mentioned \u201cinfluenza\u201d when text was searched manually. Two (13%) of the deaths were registered as pneumonia (J18); two (13%) as other respiratory disorders (J98); two (13%) were registered as sudden infant death (SIDS) and one as acute myocarditis, without mention of influenza (I40). Septicemia (A41) and myocarditis were identified as contributing causes to death on three certificates. No death certificate indicated any chronic medical conditions known to increase the risk of severe disease from influenza infection.We sought to establish whether young children showed particular susceptibility to A/Fujian/411/02-like virus infection during this winter season by analyzing sera from summers 2003 and 2004, prior and subsequent to the emergence of this antigenic drift variant. Serum samples in a nationally representative age-stratified serum cohort were analyzed for the presence of protective antibodies . The numTo assess the morbidity of influenza in different age groups we analysed observational clinical data from primary care recorded by GPs of the Weekly Returns Service (WRS). This is a national sentinel network which has been recording influenza-like illness (ILI) for over 40 years, and for which linked clinical-virological surveillance has been operational since 1994. The all-age incidences of ILI in England and Wales over a ten year period from 1994\u20132004, together with incidence rates in children ages 0\u20134 and 5\u201314 years is shown in Winter 2003\u201304 was marked by an unusually high number of severe and fatal cases of influenza in the young, following the emergence of the influenza A H3N2 antigenic drift variant A/Fujian/411/02 The range of clinical complications in UK fatal cases can be grouped into categories including (1) fulminant progression to death after an initially mild illness, (2) invasive bacterial infection, (3) respiratory tract complications and (4) non respiratory complications including myocarditis and encephalopathy. Extrapulmonary complications of myocarditis and encephalopathy were not accompanied by the detection of viral RNA from brain or heart tissue by RT-PCR, although virus was recovered from the nasopharynx. The pathological conclusions rest on histology findings, which suggests that tissue damage may occur through mechanisms other than direct viral replication, as has been previously suggested Staphylococcus aureusThe clinical microbiological findings add to the debate about the importance of bacterial co-pathogens in influenza associated fatality. Only three (18%) of the fatal cases showed evidence of significant bacterial co-infection. This is similar to findings from fatal cases in the US 2003\u201304 and also to preliminary information from the current outbreak of swine-origin influenza A H1N1, where a minority of paediatric hospital admissions had possible or probable bacterial infection In this case series over 40% of death certificates had no mention of influenza as a direct or indirect cause of death, and in over 70% of cases the diagnosis of influenza was not made until post mortem tissue was examined. The burden of influenza in young children is therefore under recognized, precisely because few influenza infections are recognized clinically A risk-factor based influenza vaccination program for children would not prevent these fatal cases as the reasons underlying susceptibility to severe disease remain cryptic. Further studies on the outcome of seasonal influenza in children will help us to predict the impact of future epidemics and will assist understanding of the outcome of infections in the immune na\u00efve host during influenza pandemics."} +{"text": "The differential p53 overexpression in different subtypes of intestinal metaplasia and gastric cancer suggests that type III intestinal metaplasia is the commonest lesion in dysplasia-carcinoma transition, particularly in the intestinal type of gastric cancer."} +{"text": "Higher concentrations of PSA and hK2 were found in tumours expressing steroid hormone receptors , and both PSA and hK2 correlated directly with PR levels.

The molecular weights of the immunoreactive species quantified by the hK2 and PSA assays were established by high-performance liquid chromatography (HPLC) and were consistent with the known molecular weights of hK2 and PSA. Together these data provide the first evidence, to our knowledge, that both malignant breast tissue and normal breast secretion contain measurable quantities of hK2, and that the degree of hK2 expression or secretion is directly proportional to the expression of PSA and steroid hormone receptors. hK2 expression may therefore be a marker of steroid hormone action in breast tissue. \u00a9 2000 Cancer Research CampaignThe recent demonstration of human glandular kallikrein (hK2) expression in a breast carcinoma cell line has suggested that this putatively prostate-restricted, steroid hormone-regulated protease may also be expressed in breast epithelium in vivo and secreted into the mammary duct system. Given that the only substrate yet identified for hK2 activity is the precursor of prostate-specific antigen (PSA), the expression of which in breast carcinomas may be associated with favourable prognosis, our purpose was to examine the expression pattern of both hK2 and PSA in breast tumour tissues. Cytosolic extracts of 336 primary breast carcinomas prepared for routine oestrogen receptor (ER) and progesterone receptor (PR) analysis, as well as 31 nipple aspirates from six women with non-diseased mammary glands, were assayed for hK2 and PSA using immunofluorometric assays developed by the authors.

Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and multiplex PCR analysis demonstrated that the high level of allelic imbalance observed in breast tumours represented loss of constitutional heterozygosity (LOH) and that this LOH extended to the telomere. Lung carcinoma (but not Wilms' tumour)-derived DNA again revealed a high level of loss of subtelomeric 17p sequences. Telomeric microsatellite polymorphisms from other chromosome arms did not show such elevated loss in either tumour type.

We used orthologous exons extracted from the University of California Santa Cruz multiple genome alignments of human and 22 Tetrapoda organisms to predict candidate enhancers and silencers that have reproducible and statistically significant bias towards annotated exonic boundaries.Auxiliary splicing sequences play an important role in ensuring accurate and efficient splicing by promoting or repressing recognition of authentic splice sites. These Tetrapoda enhancers and silencers were clustered into 15 putative core motifs based on their Markov properties. Most of these elements have been identified previously, but 118 putative silencers and 260 enhancers (~15%) were novel. Examination of previously published experimental data for the presence of predicted elements showed that their mutations in 21/23 (91.3%) cases altered the splicing pattern as expected. Predicted intronic motifs flanking 3' and 5' splice sites had higher evolutionary conservation than other sequences within intronic flanks and the intronic enhancers were markedly differed between 3' and 5' intronic flanks.A total of 2,546 Difference in intronic enhancers supporting 5' and 3' splice sites suggests an independent splicing commitment for neighboring exons. Increased evolutionary conservation for ISEs/ISSs within intronic flanks and effect of modulation of predicted elements on splicing suggest functional significance of found elements in splicing regulation. Most of the elements identified were shown to have direct implications in human splicing and therefore could be useful for building computational splicing models in biomedical research. Eukaryotic genes contain intervening sequences or introns that need to be removed from precursor messenger RNA (pre-mRNA) in a complex process termed splicing. During pre-mRNA splicing, relatively short exonic sequences are recognized by spliceosome, a large RNA-protein complex. During splicing, introns are removed and exons are joined together to form mature RNA. In addition to splice site (SS) signals at the exonic 5' and 3' ends, accurate discrimination of exons and introns requires additional auxiliary elements -3. Thesein vivo or in vitro selection methods have been employed to identify these motifs in the genomic sequences. For example, the RESCUE-ESE (Relative Enhancer and Silencer Classification by Unanimous Enrichment), a computational approach used in conjunction with experimental validation, predicted specific hexanucleotide sequences as candidate ESEs based on significantly higher frequency of occurrence in exons than in introns and also significantly higher frequency in exons with weak SSs than in exons with strong SSs we have found 88 5'SS-related and 330 3'SS-related ISEs/ISSs [see Additional File Tetrapoda superclass 3'SS and 177 (6.95%) 5'SS supporting motifs are novel and have not been previously reported in systematic screens detecting such elements. Among our predicted elements, 51.81% were octamers and 41.08% of sequences were heptamers as compared to only 6.76% hexamers and 0.35% pentamers, suggesting that motifs of larger size play important role in splicing regulation. We detected intersections with some of the cis-acting elements reported in the previous studies, but not nearly as dramatic as we saw between the intronic elements predicted for primates and Tetrapoda non-eutherian (an outgroup) clades. It demonstrates high reproducibility of our results obtained for various vertebrate lineages and supports the existence of highly conserved splicing regulatory code across vertebrates. This result also suggests the implications of elements found in regulating human splicing and may help explaining human hereditary disorders caused by mutations modulating such elements. We have established the higher evolutionary conservation for the predicted intronic cis-acting elements within mammalian intronic flanks which indicates their functional significance in exon definition. The elements found contain many of the known cis-acting factor binding sites with functionality supported by experiments with splicing reporter constructs. All these lines of evidence suggest active involvements of the predicted elements in control gradient directing spliceosome to the proper exons in the process of pre-mRNA splicing [Using the orthologous exons currently available for 23 cis-acting elements with the secondary pre-mRNA local structure in the vicinity of the SSs, except for slightly increased single strandedness detected for 5' and 3' ISSs deep inside introns.

The blocks from a total of 28 vertebrates multiple genome alignments are normally shorter than blocks from 17 vertebrates multiple genome alignments, therefore chances are higher that the block extension may not produce the correct exonic boundaries. Only the exons associated with the species not obtained through the first round should be processed in the second round.This exon set was extended with exons derived from processing of 28 vertebrates multiple genome alignments obtained from UCSC genome browser from theTetrapoda organisms. For these purposes we have examined 489,668 extended exons in primates clade (Human (Homo sapiens), Chimpanzee (Pan troglodytes), Rhesus (Macaca mulatta), Bush Baby (Otolemur garnetti)) and 476,218 extended exons from non-eutherian Tetrapoda organisms (Opossum (Monodelphis domestica), Chicken , Frog , Platypus (Ornithorhynchus anatinus), Lizard (Anolis carolinensis)) taken as the most distant outgroup among Tetrapoda organisms relative to primates.To establish the firm ground for using sequences from distantly related organisms in predicting common SS proximal elements and to estimate implication of elements found in modeling human splicing we conducted independent search for the elements in two distantly related clades of primates and non-eutherian Homo sapiens), Chimpanzee (Pan troglodytes), Rhesus (Macaca mulatta), Bush Baby (Otolemur garnetti)) and rodents (Mouse (Mus musculus), Rat (Rattus norvegicus), Guinea Pig (Cavia porcellus)) clades.To estimate the increased conservation of the intronic elements found within the intronic flanks we have used the Prank tool to Through the literature search we collected the test set of 185 human genes previously linked to autism spectrum disorder and genes implied in environmental response .

These conserved elements violate our assumption of independence of the sequences used for analysis of statistical significance; therefore within a block we counted unique element at certain position relative to SSs only once, disregarding all other identical motifs conserved since speciation from a common ancestor. To prevent substantial element underscoring in a counting round, since many of the elements at a certain position relative to a SS were sorted out due to evolutionary conservation, we shifted an element position by one within a counting region for each consecutive sequence as shown in Figure where mod is a modulo operation, counting round could be 0,1 or 2 and the sequence index goes from 1 to 2,333,379. Elements shifted by one position within the region are normally different and therefore not sorted out for being similar, which allows combining more elements in the region associated with a block under the same evolutionary pressure.These predicted groups of elements were clustered with the Mixture of Hidden Markov Models (MHMM), an unsupervised clustering method capable of modeling dependencies between neighboring positions in active motif cores [see Additional File .

Insulin resistance is an inherited genetic trait that precedes hypertension in Dahl salt-sensitive (S) rats, and is not present in Dahl salt-resistant (R) rats. Owing to the co-existence of insulin resistance and salt sensitivity of blood pressure in Dahl S, but not R rats, Dahl S rats are used to elucidate the role of dietary salt as a potential link in exacerbating both phenotypes . In light of available data, examining the impact of dietary salt on insulin resistance in Dahl S rats in terms of salt concentration and duration of exposure helps answer the following question: What percentage of dietary salt and for what duration of exposure would we expect an enhanced insulin resistance in Dahl S rats? This commentary gathers all available research done on insulin resistance in Dahl S rats in an attempt to unravel dietary salt contribution to insulin resistance in Dahl S rats. Over the past decades, insulin resistance and compensatory hyperinsulinemia have been proposed as the common disorder underlying a constellation of risk factors referred to as the metabolic syndrome or syndrome X . InsulinTo be able to address the above questions, Dahl S rats have been examined at various stages (weanlings and fully developed hypertensive rats) and with various dietary salt regimens . Weanling Dahl S rats when examined before developing hypertension and prior to sodium loading were found to be significantly insulin resistant as evidenced by their higher plasma insulin levels compared to weanling Dahl R rats . This imKnowing that Dahl S rats are genetically insulin resistant as evidenced by the presence of insulin resistance in weanling Dahl S rats as well as in fully hypertensive Dahl S rats, it's time to address our third and fourth questions which inquire about the role of salt in insulin resistance and whether a specific salt concentration and/or duration of exposure is required for salt to play a role in insulin resistance in Dahl S rats. Controversial reports in the literature have been documented with some studies proposing no effect of dietary salt in advancing insulin resistance and others proposing a significant role of salt in suppressing insulin signaling and precipitating insulin resistance in Dahl S rats. That's why, it is important to analyze all available data in terms of salt concentration and duration of exposure. Salt loading in Dahl S rats did not further increase their insulin resistance when fed 3% NaCl for 1 week , or 8% NNot only did 4 weeks of high salt diet of 8% NaCl exaggerated insulin resistance ,6and conSalt-induced oxidative stress and inflammation might be the mechanism by which high dietary salt concentration of 8% suppresses insulin signaling and precipitates insulin resistance in Dahl S rats. Inflammatory mediators enhanced by high dietary salt include the tumor necrosis factor-alpha or JNK might possibly interfere with normal insulin signaling via a number of mechanisms including: i) disruption of insulin-induced insulin receptor substrate-1 (IRS-1) and phosphoinositide-3 kinase (PI3K) phosphorylation and cellular distribution, ii) reduction in glucose transporter (GLUT4) expression levels, or iii) reduction in GLUT4 translocation to the plasma membrane -11. SuppWhile one would expect suppressed insulin signaling in Dahl S rats, Ogihara et al., reported that Dahl S rats had an enhanced insulin signaling manifested by an enhanced tyrosine phosphorylation of the insulin receptor, insulin receptor substrates, activation of PI3K and phosphorylation of Akt compared to Dahl R rats. These effects could be simply attributed to the fact that the authors starved the rats for 12 hours prior to the experiment. It is well documented that 12-hour of fasting upregulated hepatic insulin receptors in Sprague Dawley rats (from which Dahl rats were derived) Insulin resistance in Dahl S rats precedes hypertension, 2) Insulin resistance in Dahl S rats is significantly enhanced after 4 weeks of 8% NaCl, which represents the threshold for a salt-induced suppression in the insulin signaling pathway, 3) Salt-induced insulin resistance in Dahl S rats (after 4 weeks of 8% NaCl) is accompanied by an enhanced oxidative stress and inflammatory responses that is manifested by increased levels of TNF-alpha and JNK proteins, 4) Increased TNF-alpha and JNK levels might disrupt the insulin signaling pathway at the level of the insulin receptor substrates' association with either upstream or downstream molecules in the insulin pathway or via suppressing GLUT4 expression and/or translocation. Finally, it is worth mentioning that the promoter regions of the insulin receptor substrates \u20131, and \u20132 comprises putative sodium-responsive elements that might be acted upon by excess salt to suppress their corresponding activity, expression and/or function ,17. Muta"} +{"text": "The assessed lack of validated reference genes emphasizes the importance of a systematic study for their identification. For selecting candidate reference genes we have developed a simple The expression stability of 32 genes was assessed by qRT-PCR using a set of cDNAs from 24 different plant samples, which included different tissues, developmental stages and temperature stresses. The selected sequences included 12 well-known HKGs representing different functional classes and 20 genes novel with reference to the normalization issue. The expression stability of the 32 candidate genes was tested by the computer programs geNorm and NormFinder using five different data-sets. Some discrepancies were detected in the ranking of the candidate reference genes, but there was substantial agreement between the groups of genes with the most and least stable expression. Three new identified reference genes appear more effective than the well-known and frequently used HKGs to normalize gene expression in wheat. Finally, the expression study of a gene encoding a PDI-like protein showed that its correct evaluation relies on the adoption of suitable normalization genes and can be negatively affected by the use of traditional HKGs with unstable expression, such as actin and \u03b1-tubulin.The present research represents the first wide screening aimed to the identification of reference genes and of the corresponding primer pairs specifically designed for gene expression studies in wheat, in particular for qRT-PCR analyses. Several of the new identified reference genes outperformed the traditional HKGs in terms of expression stability under all the tested conditions. The new reference genes will enable more accurate normalization and quantification of gene expression in wheat and will be helpful for designing primer pairs targeting orthologous genes in other plant species.

Moreover, the Mx3000PTM software system computed the R2 value (Coefficient of determination), which represents an indicator of the quality of the fit of the standard curve to the plotted data points. The R2 values calculated for all the standard curves in each of the two biological replicates were higher than 0.994, indicating a strong linear relationship between the detected Ct values and the correspondent relative amount of template in all the amplification reactions from pooled cDNA. By plotting the Ct values of five different data-sets: 1) all 24 samples including tissues, developmental stages and temperature treatments; 2) 18 samples relative to different tissues and developmental stages; 3) six samples consisting of two temperature treatments (4\u00b0C and 33\u00b0C), each for 24 and 48 h and their controls; 4) six samples relative to the single floral organs from fully emerged spikes; 5) six samples referring to vegetative tissues and developmental stages . These data sets were used to evaluate the expression stability of the genes belonging to the four families by 18 primer pairs, 14 of them targeting specific gene transcripts of the gene families (five each for actin and \u03b1-tubulin and two each for ADP-ribosylation factor and translation elongation factor) and four primer pairs which amplified multiple transcripts for each of the four gene families . Table t differences (\u0394Ct = Ctmax-Ctmin) obtained by the 18 primer pairs for each of the five data-sets considered, whereas the complete statistics obtained by ANOVA analysis are reported in Additional file t values gives a straightforward indication of the expression stability of a particular gene; most genes with the lowest CV values showed also the lowest values of Ct range (\u0394Ct) and MST (Mean Square of Treatments) and 13 lowly expressed genes, with mean Ct values above this value , Ta2776 (RNase L inhibitor-like protein), Ta54448 and Ta54733 (Proteins of unknown function), and Ta44405 (\u03b2-tubulin), with mean Ct values between 26 and 24 cycles and moderately expressed (10 genes with more than 300 EST). Of the 13 reference genes with low Ct values, only three including more than 300 ESTs were considered moderately expressed in UniGene, whereas the expression level of the remaining 10 genes was low (<300/>100 ESTs) or very low (<100 ESTs). In our opinion, these data indicate a substantial agreement between the gene expression levels evaluated by qRT-PCR analyses and those estimated by the number of ESTs included in each corresponding UniGene cluster. Ta54963 (GABA-receptor associated protein), Ta54238 (Ubiquitin-conjugating enzyme), Ta35497 (Cyclophilin), Ta53967 (Vacuolar ATP synthase 16 kDa proteolipid subunit) exhibited the lowest gene expression variation (less than 3 cycles), while Ta44405 (\u03b2-tubulin), Ta38797 (Histone) and Ta1698 (NADP-isocitrate dehydrogenase) showed the most variable expression (more than 5 cycles).In order to avoid possible errors due to the interaction of co-regulated genes, further analyses were carried out on 32 genes involved in distinct biological processes and metabolic pathways; they comprised 28 genes selected on the basis of their uniform expression detected in UniGene and TIGR and a single gene for each of the four gene families. The expression levels could be grouped into two arbitrary categories: 19 highly expressed genes, whose mean CAs discussed in the previous paragraph, it was evident that none of the 32 selected candidate reference genes showed a constant expression under all the tested conditions in wheat. Hence, as expected, it was not possible to find an all purpose reference gene, and it would be necessary to select the most suitable one for normalizing gene expression considering the peculiar and specific experimental conditions. The relationships between expression stability of the 32 candidate genes and different types of tissues and/or experimental conditions were tested by running the programs geNorm and Normrd, Cell division control protein, AAA-superfamily of ATPases), Ta2291 , Ta53899 , Ta4045 , Ta2776 , Ta53967 , Ta54963 and Ta53919 , Ta2291 , Ta54238 , Ta54948 , Ta2776 , Ta30797 , Ta54227 and Ta4045 , Ta54227 , Ta54238 , Ta53891 , Ta54447 , Ta2291 , Ta53919 and Ta55512 , whereas Ta1698 (NADP-isocitrate dehydrogenase) and Ta44405 (\u03b2-tubulin), with M values of 0.63 and 0.59, were the least stable genes tested in our study are plotted in figure se) Fig. .

The geNorm program, in addition to the gene stability measure M, computes a normalization factor (NF) and assesses the optimal number of reference genes for generating that factor. The pairwise variations Vn/Vn+1 between two sequential normalization factors (NFn and NFn+1) are used to determine the necessity of adding the next more stable control gene for reliable normalization. Pairwise variations were calculated using geNorm for each data set to determine the optimal number of internal control genes for normalization Fig. .

The best combination of two genes suggested by NormFinder was that of Ta54227 and Ta2291, which improved the stability value to 0.030, indicating a more reliable normalization than that based on single genes. Similar results were obtained for 18 samples including tissues/organs at different developmental stages of wheat, with the lowest stability value (0.032) for Ta54227 (Table NormFinder (the second adopted program based on a model approach) ranks the best candidate references genes according to their minimal combined inter- and intra-group variation of expression. The results obtained by NormFinder analysis for the five data sets are shown in Table The stability ranking of the reference genes across the five analysed data sets obtained by geNorm and NormFinder was not identical for the genes with the most stable expression Table . In partThe expression levels of the target gene TaPDIL1-1 were used as an example to show the effect of using different normalization genes on estimating its relative expression. TaPDIL1-1 encodes the typical PDI (Protein Disulfide Isomerase) which accomplishes several metabolic functions, the most important consisting in disulfide bond formation and isomerization during the folding of secretory proteins ,40.

The method consists of two steps, each exploiting the peculiar features of these wheat-specific databases. Basically, an effective reference gene has to fulfil three main requirements: 1) moderate to high level of expression ; 2) expression in several tissues and developmental/physiological states; 3) low variation of gene expression across different tissues and developmental, physiological and environmental conditions [T. aestivum UniGene database (see Methods), which were accomplished by 177 out of the 42,256 sequence clusters therein contained. The second step consisted in the scanning of the TIGR wheat gene index database (TaGI version 11) for the identification of the TC (Tentative Consensus) or group of TCs corresponding to each of the 177 clusters previously selected in UniGene. The identification of TCs was important because these outputs are more effective for gene functional annotation and for designing gene specific qRT-PCR primers. The frequency of each TC or group of TCs linked to the 177 selected UniGene clusters was determined and was used to pinpoint the most suitable candidate reference genes to be included in a preliminary screening.To the best of our knowledge, the present research represents the first effort aimed to the identification and systematic comparison of a large number of potential reference genes and of the corresponding primer pairs specifically designed for gene expression studies in wheat, in particular for qRT-PCR analyses.

Although in our experimental conditions a single reference gene was adequate to normalize the qRT-PCR data, the use of normalization factors generated from the expression data of two or three most stable genes should be considered in future studies to improve the accuracy and reliability of expression analysis. The set of qRT-PCR specific primers for the novel and more stable reference genes developed in this study will enable more accurate normalization and quantification of gene expression in wheat. Moreover, the design of suitable primer pairs for their orthologous genes could contribute to the development of reference genes with stable expression in other plant species.In the present research we compared 20 novel candidate reference genes and 12 commonly used HKGs suitable for gene expression normalization in wheat.

CIC concentrations correlated with disease status in the early stages of treatment in 4/22 patients with GTT and 5/11 with MT. CIC assays were less sensitive than hCG and AFP as a monitor of disease, and also less specific, in that 8 patients with GTT and 5 with MT developed raised CIC concentrations during chemotherapy in spite of sustained complete remission. Measurements of CIC concentrations by present methods are neither sufficiently sensitive nor specific to be of clinical value as a tumour marker in GTT and MT, and this casts doubt on their potential value in other malignancies.

The different experimental groups treated with 20-MCA were (i) intact females, (ii) ovariectomized females, (iii) ovariectomized females with pituitary graft, (iv) ovariectomized females with 10 mug oestradiol/day for 30 days and (v) ovariectomized females with 1 mug oestradiol together with 1 mg progesteron/day for 30 days. It was possible to transmit nearly all these experimentally induced leukaemias to syngeneic mice through acellular extracts, compared with very poor transmissibility of spontaneous leukaemias in the ICRC strain, indicating functional activation of viral agents on combined treatment with carcinogen and hormones. Potency of the acellular leukaemic extract from the mice of group (ii) without the ovarian hormones was much weaker than that from mice of the other experimental groups. The leukaemogenic activity of MuLV was enhanced on serial transmission in syngeneic hosts. Leukaemic lesions of ovariectomized mice treated with 20-MCA and oestradiol were also transmissible to the sucklings of allogeneic mice of strain C3H-MTV, C57-BL and Dba-MTV. The cell-free supernatant medium of the cultures of these leukaemic lesions induced leukaemias on back inoculation into syngeneic mice. Electron microscopic studies of lesions induced with carcinogen and oestradiol consistently showed abundant intracytoplasmic type A particles. Numerous intracytoplasmic type A particles as well as some type B particles were found in the leukaemic tissues of ovariectomized females treated with MCA and oestradiol combined with progesterone. Type C particles, characteristic of MuLV were seen in the leukaemic tissues of all other experimental groups.

It is so named because it lacks expression of estrogen/progesterone receptors and does not overexpress the human epidermal growth factor receptor 2 (HER2). While only 15\u201320% of all BC cases are classified as TNBCs, they account for over 50% of BC mortality. TNBCs include the BRCA1/2- defective BCs and largely overlap with the basal-like BC group. As of today, no targeted therapies are available for these BC subtypes and despite advances in cytotoxic therapies they still carry a grim prognosis, with relapses typically occurring as soon as 3 years after treatment [TNBCs trace their origin to the genomic instability (GI) associated with defects in DNA repair (notably homology-directed repair (HDR)) and thus, compared to other BCs show increased rates of pathologic complete response following chemotherapy . Yet, deDNM2 was associated with lower relapse-free survival and very short times (3\u20135 years) to relapse after chemotherapy in TNBC. Below we provide a mechanism that explains how increased DNM2 expression may shape resistance in later stages of the disease and why it is so uniquely important for the outcome in TNBC.We have recently shown that the efficiency of HDR depends on dynamin 2 (DNM2), a large GTPase best known for its role in intracellular molecular trafficking [RAD51 might similarly reverse the HDR defects induced by DNM2 deficiency. However, although we successfully rescued the DNM2 inhibition-induced HDR phenotypes in all other cells, this was not the case for cells derived from advanced TNBCs, which remained strikingly dependent on DNM2 function for their survival after treatment with chemotherapy. We concluded that in the absence of BRCA and other proteins that control recruitment of RAD51 to the sites of DNA damage and/or stalled replication forks, RAD51 trafficking to the nucleus and subsequent cell resistance to chemotherapy was largely dependent on DNM2. This reasoning is supported by observations of aberrant cytoplasmic-to-nuclear ratios of RAD51 in late-stage TNBCs, suggesting the importance of RAD51 trafficking between nucleus and cytoplasm for the aggressiveness of TNBC [High genomic instability (GI) is a characteristic feature of TNBCs. One mechanism often employed by TNBCs to counteract GI is overexpression of RAD51, a protein central to HDR .

Further, MMS reduced the risk of neonatal and infant mortality for females, and there was no evidence of increased risk among the 26 subgroups examined.

Analysis of SMYD3 interactome indicates this protein lysine methyltransferase might be involved in calcium dependent signaling pathways through forming complexes with the phospholipase PLCB3, calcium/calmodulin dependent kinase CAMK2B, or calcineurin inhibitor RCAN3. SMYD3 is well-known as a histone H3K4 methyltransferase involved in epigenetic transcriptional regulation; however, any roles SMYD3 may play in signaling transduction remain unknown. KEGG pathway enrichment analysis reveals the SMYD3 interacting proteins are overrepresented in several signaling pathways such as estrogen signaling pathway, NOD-like receptor signaling pathway, and WNT signaling pathway. Sequence motif scanning reveals a significant enrichment of PXLXP motif in SMYD3 interacting proteins. The MYND domain of SMYD3 is known to bind to the PXLXP motif. The enrichment of the PXLXP motif suggests that the MYND domain is likely to be a key interaction module that mediates formation of some SMYD3 complexes. The presence of the PXLXP motifs in PLCB3 and CAMK2B indicates the potential role of the MYND domain in mediating complex formation in signaling. The structural basis of SMYD3 MYND domain-mediated interactions is unknown.

The results obtained indicated that organotin(IV) complexes stabilized poly(vinyl chloride) and the dimethyltin(IV) complex was the most efficient additive. The surface morphologies of poly(vinyl chloride) films containing organotin(IV) complexes were examined using an atomic force microscope and scanning electron microscopy. These showed that the surface of polymeric films containing organotin(IV) complexes were smoother and less rough, compared to the surface of the blank films. Some mechanisms that explained the role of organotin(IV) complexes in poly(vinyl chloride) photostabilization process were proposed.Three organotin(IV) complexes containing ciprofloxacin as a ligand (Ph The market for poly(vinyl chloride) (PVC) has grown significantly over the years due low production cost and its large versatility ,2,3.

In addition, the atomic force and scanning electron microscopy were used to assess the surface morphology of poly(vinyl chloride) films. The organotin(IV) complexes used act as efficient photostabilizers and reduce the photodegradation rate of poly(vinyl chloride). It is believed that organotin(IV) complexes act as hydrogen chloride scavengers, peroxide decomposers, free radical scavengers and UV absorbers. For future research using organotin complexes as PVC photostabilizers, the possible leakage of tin should be assessed in order to allow the long-term use of such additives."} +{"text": "The discovery of the involvement of defined molecular pathway(s) in tumor development and therapeutic targeting of such pathway(s) has revolutionised cancer treatment.

We found strong evidence for phylogenetic conservatism of host use at the plant family level, most likely due to substantial differences in the chemical composition of hosts, reducing the probability of shifts between host families. In contrast, the use of different plant organs represents a more labile ecological trait and ecological niche expansion that allows a finer partitioning of resources. Rhinusa and Gymnetron weevils initially specialized on plants within Scrophulariaceae and then shifted to the closely related Plantaginaceae; likewise, a gall inducing behavior evolved from non-galler weevils, possibly in response to resource competition, as galls facilitate larval development by providing enhanced nutrition and a favorable microhabitat. Results from trait-dependent diversification analyses suggest that both use of hosts within Plantaginaceae and parasitism on fruits and seed capsules are associated with enhanced diversification of Rhinusa and Gymnetron via low extinction rates. Our study provides quantitative evidence and insights on the ecological factors that can promote diversification in phytophagous insects that feed and develop inside plant tissues.Weevils (Coleoptera: Curculionoidea) represent one of the most diverse groups of organisms on Earth; interactions with their host plants have been recognized to play a central role in their remarkable diversity, yet the exact mechanisms and factors still remain poorly understood. Using phylogenetic comparative analyses, here we investigate the evolution of host use and its possible role in diversification processes of Comprising approximately 5,800 genera and more than 60,000 described species , weevilsRhinusa and Gymnetron (Curculionidae: Curculioninae), endophagous parasitic weevils whose larvae feed and develop within tissues of plant species in the families Scrophulariaceae and Plantaginaceae. The genus Rhinusa comprises approximately 40 species with a Palearctic distribution as host plants assess phylogenetic conservatism in host use by plant family and in different modes of parasitic behavior; (2) estimate ancestral states of traits associated with host plant use; and (3) assess possible effects of these traits on speciation and extinction rates within the Rhinusa/Gymnetron species complex. These analyses should provide valuable insights into the evolution of different traits of host plant use and their role in diversification processes of phytophagous insects that feed and develop inside plant tissues.Here, we use a previously inferred phylogeny from mitochondrial and nuclear DNA sequence data in conjuRhinusa representing approximately 80% of recognized species, with representatives from the three main taxonomic groups proposed by Gymnetron from the Palearctic and Afrotropical regions (approximately 40% of recognized species). Additionally, since some of the analyses performed in this study require ultrametric trees, we performed a Bayesian analysis for the same dataset of concatenated sequences using BEAST 2.1.3 ST 2.1.3 .We used Mesquite 3.1 to assesUsing the same host plant use categorization as for phylogenetic conservatism analyses, ancestral states were reconstructed across the random sample of 1,000 post burn-in trees from the analysis performed with MrBayes. We used the Bayesian approach reversible jump MCMC (rjMCMC), implemented in BayesTraits 2.0 ; the advFor comparison with the rjMCMC approach and to account for differential speciation, extinction and character transition rates in the reconstruction of ancestral states, we additionally performed ancestral state reconstructions using maximum likelihood under binary and multi-state speciation and extinction models (BiSSE/MuSSE) in the RRhinusa/Gymnetron species complex. We independently used the model to assess the effect of host plant family use (Scrophulariaceae or Plantaginaceae) and the mode of parasitism as gall or non-gall inducer. The model estimates six parameters; speciation (\u03bb) and extinction (\u03bc) rates for states 0 and 1 and transition rates from state 0 to 1 and vice versa (q01 and q10). Similarly, a multi-state speciation and extinction (MuSSE) model was employed to assess the effect of different modes of parasitism on either roots, stems or fruit/seed capsules. The MuSSE model is an extension of the BiSSE model to discrete traits with more than two states or combinations of binary traits analyzed simultaneously . Eight parsimony steps were observed against 14 expected steps at the lower confidence limit under 10,000 character randomizations of the null model. When host plant use is categorized according to the plant parts being parasitized and as gall inducer vs. non gall inducer, the distribution of characters over the Bayesian consensus tree is marginally significant at the 0.05 confidence level, that is, in both cases the difference between the expected (null model) and observed number of parsimony steps is only one. A similar trend was observed for the results from the estimation of Pagel\u2019s lambda parameter, which indicate a strong phylogenetic signal for host use by plant family (\u03bb = 1) but less phylogenetic signal for both host use as either gall or non-gall inducer and parasitic mode on different plant structures , providing enhanced nutrition and a favorable microhabitat which facilitates larval development. The use of restricted sets of host plants is phylogenetically conserved, most likely because of substantial differences in the chemical composition of their hosts, thus reducing the probability of host shifts. In contrast, the utilization of different plant organs represents a more labile ecological trait that allows a finer partitioning of resources; this ecological niche expansion is associated with enhanced diversification rates in weevils exhibiting a parasitic behavior on fruits and seed capsules. Our results show that ecological factors such as host plant use and specialized endoparasitic habits can promote diversification via low extinction rates in phytophagous insects that require plant tissues for the completion of their reproductive cycle.10.7717/peerj.6625/supp-1Supplemental Information 1Extinction rates associated with (A) use of either Scrophulariaceae or Plantaginaceae as host plant families and (B) use of different plant organs: roots, stems or fruits and seed capsules.Click here for additional data file.10.7717/peerj.6625/supp-2Supplemental Information 2Extinction rates associated with use of Plantaginaceae taxa as hosts (A) and use of fruits and seed capsules (B) estimated with MCMC analyses (BiSSE and MuSSE models) from pruned simulated trees.

Such Tau alterations range from increased total levels, imbalance of isoforms generated by alternative splicing (increased 4R-/3R-Tau ratio) or by post-translational modifications such as hyperphosphorylation or truncation. Besides, the detection in HD brains of a new Tau histopathological hallmark known as Tau nuclear rods (TNRs) or Tau-positive nuclear indentations (TNIs) led to propose HD as a secondary Tauopathy. After their discovery in HD brains, TNIs have also been reported in hippocampal neurons of early Braak stage AD cases and in frontal and temporal cortical neurons of FTD-MAPT cases due to the intronic IVS10+16 mutation in the Tau gene (MAPT) which results in an increased 4R-/3R-Tau ratio similar to that observed in HD. TNIs are likely pathogenic for contributing to the disturbed nucleocytoplasmic transport observed in HD. A key question is whether correction of any of the mentioned Tau alterations might have positive therapeutic implications for HD. The beneficial effect of decreasing Tau expression in HD mouse models clearly implicates Tau in HD pathogenesis. Such beneficial effect might be exerted by diminishing the excess total levels of Tau or specifically by diminishing the excess 4R-Tau, as well as any of their downstream effects. In any case, since gene silencing drugs are under development to attenuate both Huntingtin (HTT) expression for HD and MAPT expression for FTD-MAPT, it is conceivable that the combined therapy in HD patients might be more effective than HTT silencing alone.

Fertility declines well before general signs of menopause and is also adversely affected by common reproductive diseases, including polycystic ovarian syndrome (PCOS) and endometriosis. Understanding the factors that regulate the timing of puberty and menopause, and the relationships with fertility are important for individuals and for policy. Substantial genetic variation exists for common traits associated with reproductive lifespan and for common diseases influencing female fertility. Genetic studies have identified mutations in genes contributing to disorders of reproduction, and in the last ten years, genome-wide association studies (GWAS) have transformed our understanding of common genetic contributions to these complex traits and diseases. These studies have made great progress towards understanding the genetic factors contributing to variation in traits and diseases influencing female fertility. The data emerging from GWAS demonstrate the utility of genetics to explain epidemiological observations, revealing shared biological pathways linking puberty timing, fertility, reproductive ageing and health outcomes. Many variants implicate DNA damage/repair genes in variation in the age at menopause with implications for follicle health and ageing. In addition to the discovery of individual genes and pathways, the increasingly powerful studies on common genetic risk factors help interpret the underlying relationships and direction of causation in the regulation of reproductive lifespan, fertility and related traits. Reproductive life span from the onset of puberty, age-specific fertility rates, and twinning frequency all contribute to fertility.12 This genetic contribution to reproductive traits and diseases can result from rare mutations in specific genes and common variation at many sites in the genome each with small effects. In the last decade, genome-wide association studies (GWAS) have transformed our understanding of genetic contributions to these complex traits and diseases.13 The results of these studies have led to discovery of novel genes and pathways influencing specific traits and diseases, new discoveries in disease epidemiology, and the discovery or repurposing of candidate therapeutics.13 Results for GWAS studies for reproductive traits , breast cancer and cardio metabolic disease.28 At the other end of the distribution, delayed puberty is associated with short stature and lower bone mineral density.29Menarche occurs with maturation of the reproductive endocrine system and denotes the onset of menstrual cycles and sexual maturity for women.

Some rare mutations for IHH have been implicated in less severe delayed puberty and may contribute to the population variability in AAM.11 In contrast, activating mutations in KISS1 and kisspeptin receptor (KISS1R), and paternally inherited mutations in two imprinted genes Makorin ring-finger 3 (MKRN3) and Delta-like 1 homologue (DLK1) can result in central precocious puberty (CPP).32MKRN3 is an intronless gene located on the long arm of chromosome 15 in a cluster of imprinted genes in the region associated with Prader\u2013Willi syndrome.31MKRN3 is expressed from the paternal allele in the arcuate nucleus and inhibits the secretion of GnRH during the prepubertal period in childhood.33 Mutations associated with CPP31 include a four-base deletion in the proximal promoter of MKRN3 identified in a girl with non-familial idiopathic CPP who exhibited pubertal development around the age of seven.34 The deletion was associated with reduced promoter activity in vitro.34DLK1 is located on chromosome 14 and encodes a transmembrane protein with multiple epidermal growth factor repeats. Like MKRN3, DLK1 is expressed from the paternal allele and paternal inheritance of a complex genomic rearrangement including the translation start site of DLK1 was associated with isolated familial CPP.32 The association of CPP with loss-of-function alleles in two paternally expressed genes supports a role for imprinting affecting the timing of puberty.32The timing of puberty varies between individuals and is a highly polygenic trait with both rare and common variants contributing to the variation in age at menarche (AAM). Rare mutations in genes that disrupt the development and function of the gonadotrophin-releasing hormone (GnRH) pathway, pituitary hormones, and their receptors can result in idiopathic hypogonadotropic hypogonadism (IHH) and the absence of puberty.30 The Lin-28 Homologue 28 (LIN28B) at 6q21 was the first of the many loci identified from five independent GWAS for AAM.35 The most recent GWAS conducted in \u223c370,000 women of European ancestry identified 389 independent signals explaining \u223c7.4% of the population variance in age at menarche , and genes disrupted in rare disorders of puberty GNRH1 and KISS1.36 Analyses of the data sets for genetic effects on gene expression demonstrated positive enrichment for AAM-associated variants in five central nervous system tissues, notably the pituitary gland and hypothalamus36 supporting an important role of central mechanisms in reactivation of the hypothalamic pituitary axis and onset of puberty. Expression of 205 genes in these tissues were regulated by AAM-associated variants including higher expression of LIN28B in the pituitary gland associated with later AAM.36 Formal analysis of overlap in signals for AAM and genetic effects on gene expression in blood identified evidence for causal or pleotropic effects for 60 regions36 with the variant(s) associated with AAM driving variation of a specific genes in each region.GWAS of AAM in healthy women in European and Non-European populations have identified key genetic factors regulating puberty timing as reviewed previously.37 GWAS in 67,029 women identified 10 significant association signals for age AAM, including signals in two novel regions not reported previously in European women and one novel Japanese-specific signal in a previously reported region near PTPRD. More variants had larger effects on early, compared with late menarche timing, consistent with evidence in European studies.37In Japanese women, the mean age at menarche was 13.9 years with a strong secular trend for decreasing age at menarche to a mean age of 12.3 years for women born after 1965.38 The age at menopause (ANM) has a strong genetic component with more than 50% of variation due to genetic factors.39 A genomic analysis for age at natural menopause was conducted in ~70,000 women with a range of effect sizes from 0.07 to 0.88 years per allele. Exome array analysis identified genome-wide significant evidence for association with two correlated low-frequency missense variants in DNA helicase B (HELB). Although interpretation of the GWAS results have limitations because specific target genes in each region are yet to be determined, the results implicate a substantial role for DNA damage repair in reproductive ageing40 including repair of double strand breaks, mismatch repair and base-excision repair. Pathway analysis also suggested enrichment for a set of genes associated with POI, including MCM8, POLG and MSH5.40Menopause is defined as the permanent cessation of menstruation resulting from the loss of follicular activity. Menopause generally occurs between ages of 40\u201360 years with the average age of ~51 years in western countries.NLRP11, TMEM150B and BRSK1.41 A recent GWAS study for ANM in 43,861 Japanese women identified 16 independent genome-wide significant signals , cardiovascular disease, and effects on gynaecological, gastrointestinal, musculoskeletal, and respiratory conditions.14 The relationships are complex with non-linear relationships between AAM and T2D and cardiovascular disease.42 Early menarche increases risk for both T2D and cardiovascular disease while later menarche also increases risk for cardiovascular disease, but is neutral for T2D.11 BMI also plays a role for many of the same health outcomes. Following adjustment for body composition and socio-economic status, associations with early menarche remained significant for 14 health outcomes and associations with late menarche were significant for eight health outcomes.14 Early menarche was associated with higher risks for uterine fibroids, endometriosis and earlier natural menopause.Variation in AAM and ANM have wide-ranging effects on human health. In a study in the UK Biobank, age at menarche was associated with 26 adverse health outcomes.BRCA1, MSH6 and CHEK2 that also predispose to familial cancers.39 In addition, later age at menopause results in longer exposes to high levels of oestrogen for women. Poor DNA damage response that increases cancer risk might be expected to lead to earlier menopause, opposite to the evidence from epidemiological studies. Using the available genetic data from studies for breast cancer and age at menarche, predicted age at menopause from genetic variants showed increased risks of breast cancer with later age at menopause40 and the effects were greater in oestrogen receptor positive breast cancer. Genetic variants associated with DNA damage repair genes had smaller effects than other markers.40 Taken together, the results suggest that increased exposure to oestrogen with increased reproductive lifespan is the predominant effect on risk for breast cancer.Later age at menopause is associated with increased risks for breast, ovarian and endometrial cancer. Many of the genetic markers influencing menopause are related to DNA damage repair genes including 43 Successful reproduction denoted by age at first birth (AFB) and the associated behaviour of age at first sexual intercourse (AFS) are both moderately heritable and genetically correlated.44 Estimates from the UK Biobank for SNP-based heritability for AFS and AFB were 0.242 (s.e.\u2009=\u20090.010) and 0.290 (s.e.\u2009=\u20090.015) respectively. There was a strong genetic correlation between AFS and AFB (rg\u2009=\u20090.86) and moderate genetic correlations between menarche and both AFS (rg\u2009=\u20090.22) and AFB (rg\u2009=\u20090.24).44 GWAS identified 34 genome-wide significant signals associated with AFS in women with replication in deCODE data for the Icelandic population, and in the Women\u2019s Genome Health Study. The signals include association with intronic SNPs in the oestrogen receptor 1 (ESR1) gene that are also associated with AFB and with the number of children ever born. The ESR1 SNPs associated with AFB are unrelated to SNPs at this locus associated with puberty timing and breast cancer. On chromosome 3, the SNP rs2188151 associated with AFS is highly correlated with a missense variant in the semaphorin protein SEMA3F. The SNP also influences expression (is a cis-eQTL) for the RNA binding protein RMB6. The AFS decreasing allele is associated with later age at menarche, earlier AFB and greater numbers of children born.44Fertility traits in human populations are under genetic control.45 Follow-up analyses identified a number of genes in the genomic regions associated with AFB and number of children born that could be prioritised for functional studies. The critical SNPs on chromosome 1 associated with AFB and number of children ever born are correlated with likely functional nonsynonymous SNPs in two genes; the CREB-regulated transcription co-activator 2 (CRTC2) which acts downstream of FSH in ovarian granulosa cells, and CREB protein 3 like 4 (CREB3L4) which is highly expressed in reproductive tissues in both females and males.45 The lead SNP (rs2777888) for AFB on chromosome 3 is associated with altered DNA methylation or expression of several genes with a role in cell cycle progression and/or sperm function.45 Further functional experiments will be necessary to determine the specific genes and mechanisms of action of the large number of genetic variants influencing these important traits.A large study of genetic effects on reproductive behaviour in 62 cohorts of European ancestry identified 10 independent genomic loci associated with AFB in women, men or both.46 POI is generally defined as the onset of menopause in women under the age of 40 years. Genetic mutations have been reported in a number of candidate genes, although many reported results have not been replicated.47 There is good evidence for deleterious effects of mutations in Bone Morphogenetic Protein 15 (BMP15), Progesterone receptor membrane component 1 (PGRMC1) and the pre-mutation in the Fragile-X mental retardation 1 (FMR1) locus on the X chromosome.47 Mutations in other genes, present in low frequencies in some populations, are likely to influence POI including GDF9, Folliculogenesis specific bHLH transcription factor (FIGLA), and Newborn ovary homeobox gene (NOBOX).47 The 5-prime untranslated region of the FMR1 gene contains a CGC repeat that varies in length and expansion of the repeat to >200 copies causes Fragile-X syndrome. Repeat expansion to the pre-mutation range is associated with premature menopause, but there is no influence of shorter repeat lengths in the normal range or the longer repeats that cause Fragile-X syndrome.48Ovarian reserve is one of the crucial elements of female fertility Fig. and seve47 Although GWAS have identified multiple loci associated with POI in Chinese, Korean, and Dutch women,47 the small samples studied (<1000) have low statistical power and none identified signals exceeding 10\u22126. Pathway analysis of suggestive GWAS loci for ANM do show enrichment for known POI genes.39 There are ~80 gene disorders influencing extremes of reproductive function. The genes are involved in diverse biological processes, including control of the cell cycle, DNA damage response and repair, hormone signalling and gonadal development. Genetic variants in or near many of these genes have variable effects from very early menopause to alterations of just a few weeks.39 Future studies involving larger data sets and meta-analysis of combined GWAS will be necessary to identify risk loci associated with POF.A total of six GWAS have been conducted to identify the risk loci in POI in different populations as reviewed in detail elsewhere.49 DZ twins arise from the ovulation of two follicles after a complex process of follicle growth, selection and ovulation. The frequency of DZ twinning ranges from 6\u201315 per 1000 live births and varies with maternal age and ethnicity.50 DZ twinning is influenced by genetic factors and the DZ twinning rate for sisters of women with spontaneous DZ twins is ~2.5 times higher than the twinning rate in the general population.50 Direct evidence for genetic variants influencing rates of DZ twinning were first identified in animal studies. Domestic sheep generally have 1\u20132 offspring at each pregnancy. Linkage and positional cloning identified mutations in autosomal and X-linked genes that increased ovulation and twinning rates in heterozygous carriers.53 The mutations responsible were identified in the genes for Bone Morphogenetic Protein Receptor Type 1B (BMPR1B) and BMP15, respectively; a receptor and ligand in the ovarian signalling pathway for BMP15.53 Multiple mutations have now been reported in both BMP15 and the closely related signalling molecule growth differentiation factor 9 (GDF9).54 Physiological and genotype-phenotype studies of strains carrying the different mutations demonstrate the importance of BMP signalling, and the balance between BMP15 and GDF9 in follicle survival, maturation, and control of ovulation.54The spontaneous dizygotic (DZ) twinning rate is associated with fertility and comparisons with the frequency of monozygotic twins provide a useful index of fertility in a population.BMP15 and GDF9 have alternative phenotypes depending on whether they are heterozygous or homozygous (carried as one or two copies respectively). Increased ovulation rates occur in heterozygous carriers of the mutations as described above. In contrast, homozygous carriers with two copies of the loss-of-function mutations in BMP15 and GDF9 in sheep have streak ovaries and are completely infertile.54 These genes are candidates for infertility in women and studies in women with primary ovarian insufficiency (POI), also known as premature ovarian failure (POF), have identified mutations in both genes associated with POI.55 Confirmation through segregation studies is difficult in families with infertility disorders, but molecular and functional studies for several of these variants suggest loss-of-function effects consistent with the view that two functional copies of BMP15 are required for an adequate ovarian reserve in women.55 Low-frequency variants in GDF9 are associated with increased risk for DZ twinning in women heterozygous for these variants.56 Similar studies found no evidence that rare and low-frequency variants in BMP15 influence DZ twinning.57 Mutation screening of BMPR1B in mothers of DZ twins identified a coding variant (p.Gln294Glu) altering the same amino acid as a sheep BMPR1B functional variant.58 This mutation was not seen in other families and is of unknown significance.Some mutations in 56 In a search for common genetic variants influencing DZ twinning, a GWAS in 1980 mothers of spontaneous DZ twins and 12,953 controls identified significant association with DZ twinning for SNPs close to Follicle-Stimulating Hormone Beta Subunit (FSHB) and SMAD Family Member 3 (SMAD3).59 The risk alleles for the SNPs close to FSHB and SMAD3 increased the frequency of twin births in the Icelandic population by 18 and 9%, respectively. The lead SNP associated with DZ twinning on chromosome 15 maps to the first intron of SMAD3, strongly expressed in the human ovary, where it promotes granulosa cell proliferation and steroidogenesis.59 The region of chromosome 15q22.33 also includes SMAD Family Member 6 (SMAD6). A major gene increasing ovulation rate and twinning in cattle maps to the equivalent genomic region on bovine chromosome 10 (the location of both SMAD3 and SMAD6).60 Recent analysis of gene expression in granulosa cells from carriers and non-carriers of the cattle gene demonstrated a six-fold increase in expression of SMAD6 in gene carriers.61 SMAD6 is an inhibitor of BMP/SMAD signalling and over-expression of SMAD6 is consistent with loss-of-function mutations in BMP signalling increasing ovulation rate in sheep. Further research is required to determine whether variants associated with DZ twinning on chromosome 15 act through effects on SMAD3, SMAD6 or some other mechanism.Rare and low-frequency variants account for only a small proportion of variation in DZ twinning.63 PCOS is the most common cause of infertility64 and also increases the risk for type 2 diabetes, gestational diabetes, venous thromboembolism, cerebrovascular and cardiovascular disease and endometrial adenocarcinoma.65 The aetiology of PCOS remains unclear with diagnostic criteria proposed for PCOS66 including the National Institutes of Health (NIH), Rotterdam and Androgen Excess Society (AES) criteria. Familial aggregation and twin studies suggest genetic factors play a strong role in pathogenesis of PCOS with heritability estimates of 70%.66Polycystic ovary syndrome (PCOS) is a complex, hormonal and metabolic disorder affecting 5\u201320% of women of reproductive age globally and characterised by hyperandrogenism, ovulatory dysfunction, polycystic ovarian morphology and gonadotropic abnormalities.67 Additional studies69 identify 16 independent signals in 15 genomic regions associated with PCOS including signals near important reproductive hormone genes FSHR, LHCGR and FSHB.70 The signals also include variants in or near three epidermal growth factor genes and genes associated with diabetes.70 As with similar studies in other reproductive diseases, the total heritability explained by GWAS identified PCOS risk SNPs is relatively low (<10%).65The first GWAS conducted in Chinese patients in 2011 has direct clinical applications for planning lifestyle modification as a prevention strategy and inclusion of metformin in treatment plans for PCOS.68 Discovery of additional genetic factors and further characterisation of the signals identified will provide greater insight into the pathogenesis of the complex phenotypes in PCOS.Mendelian randomisation is an analytical method using genetic variation to investigate the likely causal relationship between an exposure trait (or risk factor) and a health outcome. Genetic variants are inherited independently and fixed at birth and subject to less confounding than other measured risk factors. Increasing evidence of association between genetic variants and many common traits means Mendelian randomisation models can use genetic variants associated with a risk factor to infer relationships with a health outcome. The models assume the genetic variants used have strong evidence for association with the risk factor and do not influence the outcome through other unrelated biological pathways. In PCOS studies, Mendelian randomisation demonstrated causal roles for higher BMI, greater insulin resistance and reduced sex hormone binding globulin concentrations in serum.7 The disease affects 7\u201310% of women and is associated with pain and infertility. Early twin studies identified evidence for genetic effects on the liability for hysterectomy,71 one of the most commonly performed surgical procedures for women. Major indications for hysterectomies in reproductive age women are endometriosis (30%) and uterine leiomyomas (>50%).73 Subsequent studies in twins on genetic influences on the liability for endometriosis estimated the heritability at ~50%.75Endometriosis is a complex disease characterised by ectopic lesions of tissue resembling endometrium in the peritoneal cavity.78 The most recent meta-analysis is the predominant receptor for oestrogen action in the endometrium.80 Genomic signals associated with endometriosis include regions flanking the gene for ESR1, signals upstream of follicle-stimulating hormone beta subunit (FSHB) known to increase FSH concentrations,79 and near the oestrogen-regulated and early response gene (GREB1) first identified in breast cancer cell lines and tumours.81 Other regions include candidate genes with roles in cell migration, adhesion and proliferation including Cell Division Cycle 42 (CDC42), Cyclin-Dependent Kinase Inhibitor 2B Antisense (CDKN2B-AS1) and Kinase insert domain receptor (KDR).84Genomic regions and genes associated with endometriosis risk are reviewed in detail elsewhere.sis Fig. identifi85 On chromosome 1, studies on genetic regulation of gene expression in blood86 and endometrium86 show the critical SNPs in this region influence expression of both the long non-coding RNA LINC00339 and CDC42. There are chromatin interactions between risk SNPs and gene promoters for both LINC00339 and CDC42.86 Luciferase reporter assays support the effect of genetic differences on the interaction between the regulatory element and the promoter of CDC42.86 Formal analysis of the overlap of signals for endometriosis risk and genetic effects on gene expression provides strong evidence that key SNPs associated with endometriosis on chromosome 1 and chromosome 12 regulate LINC00339 and vezatin VEZT expression, respectively.87Mechanisms leading to formation of lesions are poorly understand, but one source for cells initiating these lesions is thought to be cells shed from the endometrium and deposited in the pelvic cavity through retrograde menstruation.TACR3 and age at menopause), rare, low-frequency and common variants all influence the same trait.11 In other examples , rare variants cause hypogonadotropic hypogonadism while common variants influence age at menopause.11 These differences, and evidence for the different effects on ovulation rate and streak ovaries for heterozygous and homozygous mutations in BMP15 and GDF9 in sheep54 show disruption of gene function or altered regulation of the same genes can have different effects on reproductive traits and diseases.Genetic studies discussed above demonstrate the complex variation contributing to the timing of puberty, menopause, ovarian function and twinning. Genetic contributions include the effects of multiple common variants with small effects on reproductive traits and disease, and rare variants with large effects contributing to failures in development, precocious puberty, delayed puberty, premature ovarian failure and increased twinning. In some cases and genes associated with POI.40 Further research will help to understand the relationships between ovarian development, disorders of puberty, DZ twinning, POI, and age at natural menopause.Potential overlap for other traits includes genes influencing both DZ twinning and POI and endometriosis and ovarian cancer. There is a small, but significant increase in mothers of DZ twins reaching menopause before the age of 40 compared with mothers of MZ twins.92 The association signals are located in WNT4.92 Subsequent follow-up functional studies show correlated association signals for endometriosis in this region regulate LINC00339 and CDC42 not WNT4,83 and one or both target genes may also play a role in ovarian cancer risk. There is genetic association near the oestrogen receptor 1 (ESR1) locus with four independent signals for endometriosis and five independent signals for breast cancer93 overlaps completely with an association signal for ovarian cancer.94 The Polygenic risk score (PRS) combines association results from genome-wide genotyping into a single estimate of the genetic risk for a disease or trait for each individual. The PRS score is calculated from the number of risk alleles carried, weighted by the effect size estimated from the discovery sample.94 It is often standardised to a mean of zero with a standard deviation of 1 for ease of interpretation.94 The risk scores are not very informative for individual prediction, but explain sufficient variation to determine individuals at highest or lowest risk in populations, and to understand genetic contributions to related traits.13 Where samples are fully independent, calculating genetic contributions to related traits provides a powerful design reducing issues of shared environment and ascertainment in epidemiological studies. Overlap between endometriosis and ovarian cancer extends beyond the observed overlap at the chromosome 1p36 locus discussed above. Observations from epidemiological studies can be confounded due to diagnosis of endometriosis at laparoscopy close to a diagnosis of ovarian cancer. PRS analysis with genotype data from independent samples for endometriosis and ovarian cancer showed shared genetic risk between endometriosis and most histotypes of ovarian cancer95 suggesting some common molecular pathways for the two diseases including the overlap at chromosome 1p36. Prediction of individual risk is improving for some diseases with better estimates of the genetic risk factors. While not sufficiently predictive in isolation, risk scores may be used in combination with other clinical data for patient stratification. The application of risk prediction to inform breast cancer screening is being evaluated in the population based Women Informed to Screen Depending On Measures of risk (WISDOM) study.96In addition to discovery and overlap in effects for individual genes, GWAS data provides powerful approaches to understand shared genetic risk between traits and diseases. Genome-wide SNP genotype data from a discovery sample can be used to estimate the genetic variation due to common SNPs or SNP heritability, and to calculate a polygenic risk score for individuals in an independent sample.97 and number of children ever born.97 Results show a significant negative genetic correlation between number of children ever born and the age at first birth suggesting genes contributing to later first birth are associated with fewer children.97 These relationships are complex because environmental effects and demographic changes also play a role with women choosing to delay childbearing in many countries. Relationships between age at first birth and lifetime number of children are also associated with genetic effects on twinning. Mothers of twins tend to have an earlier age at first birth and raise more children to adulthood in favourable environments.99 Polygenic risk score analysis from the GWAS results for DZ twinning suggest genes contributing to DZ twinning may partly explain genetic effects on fertility. The polygenic risk score for DZ twinning was significantly associated with DZ twinning in an independent sample from Iceland.59 In this sample, the risk score for DZ twinning was associated with a higher likelihood of having children, earlier age at first birth, and greater number of children.59As noted earlier, there are significant additive genetic effects for age at first birth100 This epidemiological evidence is supported by the Mendelian randomisation analyses demonstrating the causal relationship between delayed natural menopause and increased breast cancer risk.40 Understanding these relationships is further complicated by effects of variation in body mass index (BMI). There is a strong inverse genetic correlation between AAM and BMI.36 Thirty-nine signals overlap between AAM and BMI, but most AAM signals make some contribution to adult BMI.36 Using information from different genetic studies allowed estimates of the direct effects of AAM on sex-steroid-sensitive cancers after adjusting for genetically predicted BMI. In these models, later AAM was associated with reduced risks for breast, ovarian and endometrial cancers.36 Analysis of cancer subtypes suggests effects were most strongly associated with oestrogen receptor positive breast cancer and serous ovarian cancer. The effects of earlier puberty timing on higher risks of the sex- steroid sensitive cancers might be related to longer duration of exposure to sex steroids and/or increased activity of the hypothalamic-pituitary axis associated with earlier puberty and reproductive traits including dizygotic twinning.Genetic studies can also inform complex relationships between reproductive traits and related health outcomes. A large-scale meta-analysis supported an association of early menarche and late menopause with increased risk of breast cancer and demonstrated that excess risk associated with advancing menarche by one year was higher than excess risk associated with lengthening menopause by one year.Recent studies have made great progress towards understanding the genetic factors contributing to variation in traits and diseases influencing female fertility. These genetic studies are providing important insights into the complex biology contributing to female fertility. The data emerging from GWAS demonstrate the utility of genetics to explain epidemiological observations, revealing shared biological pathways linking puberty timing, fertility, reproductive ageing and health outcomes. For example, many variants influencing menopause suggest genes and pathways with known roles in DNA damage/repair with implications for follicle health and ageing, although we do not yet have a full picture of the mechanisms responsible.The effect sizes for common variants are small and, as emphasised in this and other reviews, large studies are essential to identify a substantial fraction of common variants underlying variation for these traits and diseases. In addition, GWAS identify genomic regions, but not the specific genes and pathways regulating variation in traits and diseases. To date, we lack definitive evidence for the causal variants and target genes for most of these results. Despite these gaps, examination of potential candidate genes in the multiple regions identified through GWAS provide tantalising evidence for common pathways affecting reproductive lifespan and fertility.101 This in turn will provide much better understanding of the specific pathways regulating individual components of reproductive lifespan and fertility, and the complex interactions between pathways and health outcomes. The knowledge gained will suggest possible interventions and ways to better predict and minimise health impacts of these important life events.The challenge now is to provide functional evidence for the specific genes and pathways regulated by the genetic variation influencing fertility. Multiple lines of evidence from both functional and genomic studies will be required to identify these gene targets and the mechanisms responsible. This is becoming more feasible with advances in genomics, large-scale publically available data, and genome editing.Genetic risk scores from common variants are not able to predict disease risk for individuals. As the estimates improve from more powerful studies, they may be able to predict women at higher or lower risk for specific diseases and this may be useful in some diagnostic settings. Genetic variants associated with natural menopausal timing also influence the menopausal timing in women undergoing radiation or chemotherapy suggesting that in the future, genetic risk prediction models could be useful for counselling related to family planning, lifestyle choices or use of modern techniques for fertility preservation such as oocyte cryopreservation.Epidemiological evidence for comorbidity between traits can be difficult to interpret because of the issues of sample ascertainment. Genetic risk scores add a valuable method to gain insight into the complex relationships in the overlap between traits and diseases. These analyses will also improve as the risk scores can be derived from increasingly powerful studies to help interpret the underlying relationships and direction of causation in the regulation of reproductive lifespan, fertility and related traits."} +{"text": "The USDA Forest Service and University of California researchers have developed a simple and inexpensive passive sampler for monitoring air concentrations of HNO3.

This poster will present the results of an ongoing program evaluation to determine the effects of the intervention on PWDs\u2019 engagement in (1) communication with others and (2) art/creative activity. A two-member analysis team independently coded ethnographic field notes utilizing operational definitions of PWDs\u2019 observed behavior during momentary time sampling, and recording events of communication and art engagement using the modified ENGAGE measure . Results across sessions (N=97) reveal communication engagement significantly exceeded art engagement , t (96)=20.85, p=0.001). These results suggest that engagement in reminiscence via intergenerational contact is a fundamental feature in comparison to art and creative activity within the ATL program. Exploratory qualitative content analysis of ethnographic field notes by a three-member coding team identified two key themes within the communication engagements. These emergent themes included validation of personhood and reminiscence of family ties. More studies are needed to determine if the scope and reach of intergenerational interventions may be increased through the nationwide translation of the ATL program."} +{"text": "An outbreak of feline panleukopaenia virus (FPLV) infection was diagnosed by pathology, electron microscopy and polymerase chain reaction (PCR) in vaccinated captive-bred subadult cheetahs in South Africa. Subsequent to this disease outbreak, 12 cases of FPLV diagnosed on histology were confirmed by PCR in captive African black-footed cat, caracal, cheetah, lion, ocelot and serval. Phylogenetic analyses of the viral capsid protein gene on PCR-positive samples, vaccine and National Center for Biotechnology Information (NCBI) reference strains identified a previously unknown strain of FPLV, present since at least 2006, that differs from both the inactivated and the modified live vaccine strains. A previously described South African strain from domestic cats and cheetahs was identified in a serval. Surveys of FPLV strains in South African felids are needed to determine the geographical and host species distribution of this virus. Since non-domestic species may be reservoirs of parvoviruses, and since these viruses readily change host specificity, the risks of FPLV transmission between captive-bred and free-ranging carnivores and domestic cats and dogs warrant further research. Felis domesticus). FPLVs are classified under the family Parvoviridae and are related to mink enteritis virus (MEV) and canine parvovirus (CPV) infection, the first viral disease identified in cats, is one of the most common viral diseases of domestic cats (Acinonyx jubatus) , ocelot , puma (Puma concolor), Siberian tiger , and spotted cat (Leopardus tigrinus) , arctic fox (Vulpes lagopus) and raccoon (Procyon lotor), and is genetically very similar but distinct from CPV-like viruses from dogs (Canis familiaris) and raccoons , seven cheetahs, three lions, one ocelot and two servals . Clinical signs and pathological findings were not available from many of these cases. Before the 2012 cheetah outbreak molecular diagnostic confirmation of suspected FPLV cases was not readily available in South Africa. To investigate prior suspected or confirmed cases of FPLV molecular diagnostic testing was performed on archived tissue samples from felids in the NZG Biobank (Cases A\u2013G), including both suspected and histologically typical FPLV cases. Cases were from Gauteng and North West provinces and included one African black-footed cat (Felis nigripes), a domestic cat, three cheetahs and two lions. Samples from a puma, a leopard (Panthera pardus) and an ocelot in which clinical and histological evidence of FPLV was absent (Cases i\u2013iii) were included as negative control cases. DNA was also extracted from current Fellocell\u00ae and Fel-O-Vax\u00ae vaccines. All the samples are archived at the NZG Biobank.Subsequent to the outbreak in cheetahs, animal carcasses, a rectal swab, formalin-fixed tissues or formalin-fixed paraffin-embedded tissues (FFPE) from various single or multiple cases in captive felids were submitted to the NZG for pathological examination and/or molecular diagnostic testing for FPLV infection by the owners, veterinarians and pathologists throughout South Africa (Cases 6\u201320). Submitted cases of suspected or confirmed FPLV based on clinical signs and typical macroscopic and histological findings, or diseases presenting with similar signs, included two caracals (TM Tissue MiniPrep kit (Zymo Research). DNA from FFPE samples were extracted using the MasterPure\u2122 Complete DNA & RNA Purification Kit (Epicentre) following the manufacturers specifications. Molecular analysis of the parvovirus genome from all the isolates was conducted by amplification of a ~1300 base pair (bp) region of the viral capsid protein (VP2) gene treatment, cycle sequenced using the BigDye V3.1 (Applied Biosystems) chemistry and run on a 3130 genetic analyser (Applied Biosystems). The resulting sequences were analysed and aligned using the ClustalX parvovirus reference strains. Results from NJ (10 000 bootstrap replicates) and BA (1 million generations) are presented in Clinical signs were described in detail only in the initial cheetah outbreak (Cases 1\u20135) and included pyrexia, haemorrhagic diathesis , hypersaOn necropsy examination, the cheetah cubs showed similar lesions including variable dehydration, mild acute diffuse tissue congestion, and moderate acute intestinal serosal congestion and haemorrhage . VariablEscherichia coli was obtained from the intestine from Case 1 and normal intestinal bacterial flora from Case 3. On negative contrast electron microscopy intestinal contents contained small numbers of parvovirus particles (Case 1).Histologically, extensive necrosis of the intestinal epithelium was accompanied by villous collapse, marked hyperplasia of scanty remaining epithelium, and a thick coat of fibrin, necrotic cellular debris and myriad bacteria on the mucosal surface . In addiThe pathological lesions were consistent with FPLV infection with secondary bacterial enteritis and septicaemia. Additional pathological findings included moderate diffuse acute interstitial pneumonia with moderate multifocal acute pulmonary oedema ; multifocal acute moderate necrohemorrhagic bacterial gastritis as well as lingual and gastric candidiasis, mild serosanguinous hydropericardium and hydrothorax and acute moderate segmental renal tubular necrosis (Case 2); oesophageal and gastric candidiasis and acute mild multifocal pancreatic necrosis (Case 3); and mild acute multifocal necrotising aspiration pneumonia (Case 5). All the cubs were in good body condition at the time of death and showed mild to moderate diffuse adrenocortical hyperplasia.\u00ae vaccine. Clade 2 is represented in the current dataset by one sample (Case 10), which clustered with previously described South African strains of FPLV isolated from a domestic cat (1999) and two cheetahs (2000) as well as an FPLV strain isolated from a wildcat and a mink in the USA (1995). This strain is 99.99% similar to the Fellocell\u00ae vaccine . All the samples from this study clustered separately from CPV (98% similarity) and clustered in two clades. Most of the positive cases (Clade 1) clustered closely (99.94% \u2013 100%) with reference samples from carnivores in Japan and the United States of America (USA), and were similar to the Fell-O-Vax vaccine .Clinical features, pathology, electron microscopy and molecular diagnostic tests confirmed the presence of a previously unreported strain of FPLV in the cheetah cubs in the initial outbreak (Cases 1\u20134). This strain was also detected in archived samples from a lion that died in 2006 (Case A) and an African black-footed cat that died in 2007 (Case B), as well as in samples submitted from other captive felids that died throughout the country after November 2012, including cheetahs , a caracal (Cases 15), a lion (Case 14), an ocelot (Case 12) and a serval (Case 6).et al. The testing of archived samples confirms that the strain from Clade 1 was present in felids in at least North West province before the initial cheetah outbreak and Clade 1 virus subsequently caused disease in unvaccinated felids in Gauteng and North West. Clade 1 strain apparently co-exists with the previously described strain , F10 products or swimming pool chlorine (2.67 g/L water). Biosecurity measures included staff movement from clean to infected enclosures for feeding and inspections; new and frequently changed cleaning cloths as well as overalls and boots for all staff; hand gels and body sprays of F10 products used when moving between enclosures.et al. Positive cases were detected from fresh and frozen tissue, a faecal swab and FFPE intestinal samples from 16 animals clinically and pathologically diagnosed as suffering from FPLV or suspected FPLV . Three cAlthough infections with viruses of the feline parvovirus subgroup have been reported before in several wild carnivore species, including African felids, this study reveals the first in-depth insight into strain diversity within captive felids in South Africa and the first documented cases of FPLV infection in the African black-footed cat and caracal. Further surveys are needed to determine the geographical and host species distribution as well as the genetic variability of FPLV in these species. Vaccine failure, inadequate vaccination and stress may be predisposing factors in the susceptibility to disease. Retention of the current vaccination programme as well as good hygiene practices at breeding and rearing facilities is recommended for the prevention and control of the disease."} +{"text": "Containerized plant production represents an extremely intensive agricultural practice; 40,000 to 300,000 containers may occupy one acre of surface area to which a large amount of chemical fertilizer is applied. Currently, recommended fertilizer application rates for the production of containerized nursery ornamental plants are in excess of plant requirements, and up to 50% of the applied fertilizers may run off or be leached from containers. Among the nutrients leached or allowed to runoff, nitrogen (N) is the most abundant and is of major concern as the source of ground and surface water pollution. In this report, current N fertilizer application rates for different container-grown nursery ornamental plants, the amount of nitrate leaching or runoff from containers, and the potential for nitrate contamination of ground and surface water are discussed. In contrast, our best N management practices include: (1) applying fertilizers based on plant species need; (2) improving potting medium's nutrient holding capacity using obscure mineral additives; (3) using controlled-release fertilizers; and (4) implementing zero runoff irrigation or fertigation delivery systems that significantly reduce nitrate leaching or runoff in containerized plant production and encourage dramatic changes in N management."} +{"text": "PRNP reported from several countries.

The benefits of community engagement are often stressed in instrumental terms, particularly with regard to promoting recruitment and retention in studies. Less emphasis has been placed on the value of community engagement with regard to ethical good practice, with goals often implied rather than clearly articulated. This article outlines explicitly how community engagement can contribute to ethical global health research by complementing existing established requirements such as informed consent and independent ethics review. The overarching and interlinked areas are (1) respecting individuals, communities and stakeholders; (2) building trust and social relationships; (3) determining appropriate benefits; minimizing risks, burdens and exploitation; (4) supporting the consent process; (5) understanding vulnerabilities and researcher obligations; (6) gaining permissions, approvals and building legitimacy and (7) achieving recruitment and retention targets.

The Indiana State Department of Health (ISDH) and the Dubois County Health Department (DCHD) coordinated the public health response to this outbreak, which was the first detection of HPAI A(H7N8) in any species ( On January 15, 2016, ISDH was notified by the Indiana State Board of Animal Health that HPAI A(H7N8) virus had been confirmed in a commercial turkey flock in Dubois County, Indiana. In accordance with USDA guidelines (ISDH and DCHD recommended that responders be monitored during the response and for 10 days after their last possible exposures for influenza-like illness (ILI), defined as either 1) self-reported fever with cough or sore throat, or 2) conjunctivitis with or without additional symptoms. All responders received instructions to seek medical attention and contact public health authorities if they developed ILI during the 10-day period. USDA monitored federal employees, contractors, and subcontractors who participated in the response. ISDH and DCHD monitored state and local responders, using adapted, unpublished USDA/CDC public health monitoring procedures for HPAI A(H5) that were first circulated in September 2015 and later updated in November 2015. Responders were classified into three risk categories: 1) no risk, 2) low but not zero risk, and 3) some risk. Responders with low but not zero risk were those exposed to infected or potentially infected birds or their environments while using appropriate personal protective equipment (PPE) were monitored for some risk exposures, 67 (40%) were monitored for low but not zero risk exposures, four (2%) were monitored with no risk status recorded, seven (4%) had no exposure, five (3%) declined to be monitored, and nine (5%) were lost to follow-up. Among the 145 persons who were monitored, 14 (10%) reported current or recent ILI symptoms, 12 (86%) of whom were tested during January 16\u201322, 2016, with a median of 1 day from onset to medical evaluation. Nine patients had nasopharyngeal/oropharyngeal specimens collected, one had a conjunctival specimen collected, and two had both types of specimens collected. Specimens were tested for influenza A virus by real-time reverse transcription\u2013polymerase chain reaction at the ISDH Laboratories; all 12 patients tested negative for influenza A virus.On January 15, 2016, Indiana activated its Emergency Operations Center with staffing consistent with the Federal Emergency Management Agency Emergency Support Functions (ESFs) appropriate to the response .ISDH\u2019s major actions during the public health response included developing a demobilization packet for responders, issuing a Health Alert Network advisory to Dubois County and surrounding counties with recommendations for health care providers, establishing syndromic surveillance queries in the Indiana Public Health Emergency Surveillance System to detect community-acquired cases, and developing recommendations for the use of antivirals.Public health monitoring procedures for H7N8 responders were successfully implemented during this outbreak; no cases of zoonotic avian influenza infection were detected. The risk for zoonotic transmission in this outbreak was thought to be low at the time. No human infections with influenza A(H7N8) viruses had ever been reported,The unpublished USDA/CDC public health monitoring procedures that were adapted for use in this outbreak were developed for responders to an HPAI A(H5) outbreak. HPAI and LPAI are differentiated based on genetic features and the extent to which these viruses produce morbidity and mortality in poultry . The updated plan will allow for passive monitoring of persons wearing PPE and responding to certain influenza A H5 and H7 viruses that have caused outbreaks in the United States but have no history of causing human infections . The updated plan will also cover all avian influenza viruses of public health concern, including both HPAI and LPAI viruses.Several challenges to human health monitoring were identified during this outbreak. First, receipt of contact information for responders by the local health department was delayed in the initial stages because of the urgency and complexity of the animal health response. Complete information for exposed responders was not received by DCHD until 5 days into the response (on January 20), although preliminary information was provided earlier. Second, tears in Tyvek suits were reportedly common because of the nature of animal handling activities; this could have resulted in misclassification of disease exposure risk. Finally, mobilization of a large number of responders within a short period raised concerns that PPE and monitoring recommendations were not being implemented consistently.Enhanced communication and information sharing among local, state, and federal agencies would improve identification of exposed persons and coordination of specimen collection, testing, and medical care for ill responders. This could be accomplished by 1) effectively communicating public health needs and recommendations to all stakeholders in the response; 2) identifying processes for early identification of exposed persons ; 3) designating a local/state/federal public health department liaison to be embedded in the unified command post to facilitate coordinated implementation of human health monitoring, including obtaining names and contact information for responders; and 4) conducting daily debriefings with safety officers in the incident command system to identify injuries or breaches in PPE that could elevate responder risk. In future outbreaks, ISDH will also recommend that responders to outbreaks of AI viruses of public health concern entering the exclusion zone (hot zone) and contamination reduction zone (warm zone) in infected premises (Prolonged or close contact with birds infected with avian influenza (AI) virus increases the risk for zoonotic infection in humans. Monitoring exposed persons for 10 days might facilitate early detection and reporting of zoonotic AI.Monitoring procedures for highly pathogenic AI (HPAI) responders were successfully implemented during a 2016 outbreak of HPAI A(H7N8) in commercial turkey flocks in Indiana. No human cases of AI were identified.Collaboration among local, state, and federal partners is essential during AI outbreak responses. Monitoring should be considered for all responders who had contact with infected birds or their environments, regardless of whether personal protective equipment was worn."} +{"text": "In November 2011, a government hospital physician in Shibganj sub-district of Bangladesh reported a cluster of patients with fever and joint pain or rash. A multi-disciplinary team investigated to characterize the outbreak; confirm the cause; and recommend control and prevention measures.Shibganj's residents with new onset of fever and joint pain or rash between 1 September and 15 December 2011 were defined as chikungunya fever (CHIKF) suspect cases. To estimate the attack rate, we identified 16 outpatient clinics in 16 selected wards across 16 unions in Shibganj and searched for suspect cases in the 80 households nearest to each outpatient clinic. One suspect case from the first 30 households in each ward was invited to visit the nearest outpatient clinic for clinical assessment and to provide a blood sample for laboratory testing and analyses.We identified 1,769 CHIKF suspect cases from among 5,902 residents surveyed (30%). Their median age was 28 (IQR:15\u221242) years. The average attack rate in the sub-district was 30% (95% CI: 27%\u221233%). The lowest attack rate was found in children <5 years (15%). Anti-CHIKV IgM antibodies were detected by ELISA in 78% (264) of the 338 case samples tested. In addition to fever, predominant symptoms of serologically-confirmed cases included joint pain (97%), weakness (54%), myalgia (47%), rash (42%), itching (37%) and malaise (31%). Among the sero-positive patients, 79% (209/264) sought healthcare from outpatient clinics. CHIKV was isolated from two cases and phylogenetic analyses of full genome sequences placed these viruses within the Indian Ocean Lineage (IOL). Molecular analysis identified mutations in E2 and E1 glycoproteins and contained the E1 A226V point mutation.The consistently high attack rate by age groups suggested recent introduction of chikungunya in this community. Mosquito control efforts should be enhanced to reduce the risk of continued transmission and to improve global health security. Togaviridae family, have been reported from several countries in Africa, Asia and the Western Pacific since 1952.[Aedes aegypti and Aedes albopictus mosquitoes are the two primary vectors transmitting CHIKV to humans.[Epidemics of chikungunya fever (CHIKF) caused by chikungunya virus (CHIKV), a mosquito-transmitted alpha virus of the nce 1952.

The outbOn 5 November 2011, the primary healthcare physician managing the government hospital in Shibganj sub-district of Chapainababganj district in northwestern Bangladesh reported a cluster of 19 patients with fever, severe joint pain and/or rash to the Institute of Epidemiology, Disease Control and Research (IEDCR) of the Ministry of Health and Family Welfare. In response, a collaborative, multi-disciplinary investigation team from IEDCR and icddr,b conducted an investigation to (i) characterize the outbreak in terms of person, place and time; (ii) confirm the cause; and (iii) identify prevention and control approaches for future outbreaks.The team visited the hospital in the affected sub-district and conducted unstructured interviews with local healthcare providers, including physicians and field workers, to collect preliminary information about the clinical features, laboratory findings, and geographical distribution of affected patients. Based on these interviews, the experience of a similar outbreak in 2008, and giveGiven the lack of information regarding the prevalence of chikungunya fever from Bangladesh during the investigation period in 2011 and because the preliminary survey findings suggested a widespread distribution of suspect cases, the investigation team conducted a house-to-house syndromic survey in all of the 16 unions of Shibganj to calculate the attack rate. Using the attack rate of 34% as observed during the preliminary survey and assuming a type 1 error of 0.05, a precision of 5%, an average of 5 persons per household, a design effect of 3.0 to take into account the cluster sampling design and a non-response rate of 20% at the household level, we calculated a required sample size of at least 1,280 households from the 16 unions of Shibganj for the syndromic survey. In each To obtain clinical histories and collect biological specimens, data collectors invited one suspect case from each of the first 30 households visited in each ward to come to the nearest primary healthcare clinic to complete a clinical assessment and to provide a blood sample for testing. If a household had more than one eligible respondent, the data collectors requested the eldest household member present during the survey to select one resident for participation. Physicians on the team later interviewed and physically examined suspect cases who came to the local clinics.To test for IgM antibodies to CHIKV, trained phlebotomists collected 5 ml venous blood from each suspect case who had presented to the clinic and consented to participate. Phlebotomists stored all blood samples immediately after collection at 4\u22128\u00b0C. The samples were centrifuged on the same day and the sera were stored in the local hospital refrigerator and later transported in cool boxes to the Virology Laboratory of IEDCR. At IEDCR, each serum sample was divided into three aliquots before storing at -70\u00b0C until testing. At the beginning of the investigation, we only had 300 rapid test kits available, so we tested 300 randomly selected samples out of the 367 sera. We tested 338 randomly selected aliquots out of the 367 samples for anti-CHIKV immunoglobulin M (IgM) antibodies using an enzyme-linked immunosorbent assay (ELISA) test kit that was also available with our group during the investigation in the Virology Laboratory of IEDCR following the manufacturer\u2019s guidelines.Acute sera that had been collected from suspect cases within two days of illness onset and tested negative for IgM antibodies to CHIKV were later tested for viral RNA using quantitative reverse transcription polymerase chain reaction (RT-qPCR). The seraPhylogenetic analysis was performed as previously described. ChikunguAedes aegypti bred mainly in the water collected in artificial containers in the environment of human settlements in Asia,[Aedes albopictus bred predominantly in natural containers including coconut shells, leaf axils and tree holes, team entomologists looked for mosquito larvae in both man-made and natural water containers.[The entomological investigation was conducted during December 15\u221231, 2011 and focused on identifying vector species. Given that in Asia, while Aentainers. To collentainers.We divided the total number of suspect cases by the total number of household residents surveyed in each cluster ward within each union composed of the 80 households nearest to an outpatient clinic in the ward to calculate the attack rates by cluster. We estimated the attack rate within the sub-district by calculating the mean of attack rates for the 16 clusters combined. We also calculated the attack rates by 5-year age groups and gender. We used the number of suspect cases instead of confirmed cases to estimate the attack rate because we only collected and tested the serum samples from a sub-set of suspect cases who later came to clinics for clinical assessment and sample provision. For the sub-set of patients who came to the clinics for clinical evaluation, we described their clinical features. Since many respondents were still symptomatic during the clinical survey, we estimated the median follow-up time from symptom onset till recovery for each of the four symptoms including joint pain, joint swelling, debilitating weakness and severe myalgia. Previous authors have suggested that length of follow-up time should be extracted from the time frame where the Kaplan Meier estimate was most stable. We consiThe Institutional Review Board (IRB) of IEDCR and the Ethical Review Committee (ERC) of icddr,b considers outbreak investigations that primarily aim to control outbreaks as public health practice and approval by research ethics committee is not required. This is in line with national and international ethical guidelines including the 1991 International Guidelines for Ethical Review of Epidemiological Studies by the Council for International Organizations of Medical Sciences.\u201349 SeverWe obtained informed oral consent for voluntary participation from adults and verbal assent from children. Past experience of research in similar settings suggested that obtaining written informed consent was difficult, time consuming and resource-intensive when dealing with illiterate participants who were often very cautious, as they did not know what they were signing or whether the signed document could be used against them. As a result, verbal informed consent procedure was allowed during this emergency outbreak situation, where the majority of the affected population were illiterate and ill, as obtaining written informed consent was considered unnecessary and not in the patient and community\u2019s best interest. The investigation team member who was informing a participant signed a form stating that the appropriate information was provided and verbal consent received before beginning any information and/or sample collection or any kind of investigation.The team identified 30 suspect cases from the hospital initially. These cases resided in six different unions within Shibganj. Their median age was 35 years and 45% were males. Fever (100%), polyarthralgia (90%), malaise (83%), severe weakness (66%), rash (48%), itching (38%), and headache (35%) were the predominant symptoms. Forty percent (12/30) of these patients had evidence of IgM CHIKV antibodies in their sera when tested using the rapid assay.We surveyed a total of 5,902 individuals from 1,283 households in the 16 unions of Shibganj. Of these, 1,769 (30%) met the suspect case definition. The median age of suspect cases was 28 (IQR:15\u221242) years. The average attack rate in the sub-district was 30% (95% CI: 27%\u221233%). Attack rates varied from 10%\u221244% across the 16 selected clusters within the 16 unions of Shibganj . The meaAmong the 1,769 suspect cases, 480 (27%) were invited to participate in the clinical survey and to provide blood samples. Seventy-nine percent (377/480) of the invited suspect cases gave consent for the clinical survey and physical examination, and 367 (77%) provided a blood sample. Among the serum samples tested with the rapid test, 73% were positive for chikungunya whereas IgM anti-CHIKV antibodies were detected in 78% (264/338) of the samples that were tested by ELISA. We found that the suspect cases tested within one week of illness onset (43%) were less likely to have IgM antibodies against Chikungunya compared to the suspect cases tested more than 60 days post illness onset (98%) .Among the 377 cases interviewed during the clinical survey, the median age was 40 years (IQR:30\u221250 years); 64% (241/377) were females; and 92% (347/377) were Muslims. The main clinical symptoms included fever (100%), joint pain (88%), debilitating weakness preventing routine activities (55%), rash (51%), severe myalgia (44%), itching (33%) and joint swelling (16%) . Thirty-In addition to fever, the predominant symptoms of serologically-confirmed cases (n = 264) among those who had provided sera after coming to the clinic included joint pain (97%), weakness (54%), myalgia (47%), rash (42%), itching (37%) and malaise (31%). The rashes were found on the trunk (36%), lower limbs (36%), palms and soles (33%), upper limbs in (14%), and face (8%). Of those who developed joint pain, 93% (238/256) reported pain in multiple joints and joints of the lower limbs were involved in 90% (230/256) of the cases. Among the cases reporting joint pain, severe pain that prevented sleep was reported by 61% (156/256), moderate pain that caused pain on movement was reported by 23% (59/256) and minor pain that did not interfere with daily activities but caused discomfort was reported by 17% (43/256). Severe weakness was reported by 40% (105/264), debilitating myalgia by 36% (94/264) and severe joint swelling by 14% (37/264). On examination, team physicians found restricted joint mobility in 23% (59/256) of the serologically confirmed cases. The rashes were maculopapular in 62% (69/112), macular in 33% (37/112) and popular in 5% (6/112) of the suspect cases with rashes. The median durations of symptom persistence of joint pain was 31 days, while joint swelling persisted for 7 days, debilitating weakness and severe myalgia, each persisted for about 12 days in the majority of this sub-set of confirmed cases . FurtherTwo out of the four patients from this outbreak in Shibganj and the single patient from the concurrent outbreak in Dohar sub-district of Dhaka whose acute sera were collected within two days of illness onset had detectable Chikungunya virus RNA with RT-qPCR. However, none of them had IgM antibodies in their sera. The three viral isolates, obtained from the two outbreaks including this outbreak in Shibganj (n = 2) and in Dohar (n = 1), clustered with strains from the 2006 Indian Ocean lineage and were most closely related to the Indian/Asian geographic isolates rather than the African isolates within that lineage . The sizAedes aegypti or Aedes albopictus mosquitoes during the investigation. The team found mosquito larva from only 1/160 households surveyed and the larvae that hatched from this household in IEDCR\u2019s Entomology laboratory yielded Culex quinquefaciatus species.The team did not find any larvae of Aedes aegypti or Aedes albopictus mosquitoes during the investigation.We identified CHIKF suspect cases among 30% of the residents surveyed across the 16 unions in Shibganj during the syndromic survey. The median age of suspect cases was 28 years. The lowest attack rate was found in children <5 years (15%). Anti-chikungunya virus (CHIKV) IgM antibodies were detected by an enzyme-linked immunosorbent assay (ELISA) in 78% of the case samples tested. In addition to fever, the predominant symptoms of serologically-confirmed cases, included joint pain (97%), weakness (54%), myalgia (47%), rash (42%), itching (37%) and malaise (31%). The median durations of symptom persistence of severe joint pain was 31 days, while severe joint swelling persisted for 7 days, debilitating weakness and severe myalgia, each persisted for about 12 days in the majority of this sub-set of confirmed cases. Among the sero-positive patients, 79% sought healthcare from outpatient clinics. CHIKV was isolated from two cases and phylogenetic analyses of full genome sequences placed these viruses within the Indian Ocean Lineage (IOL). Molecular analysis identified mutations in E2 and E1 glycoproteins and contained the E1 A226V point mutation. We did not find any larvae of The clinical syndrome of fever, multiple joint pain, with or without debilitating weakness or severe myalgia was consistent with previous CHIKF outbreaks., 5, 33 TThough several outbreaks have reported an increased propensity to cause clinical illness among females, our syndAedes albopictus larvae breeding in the numerous wet earthen and clay pots that were used for pottery.[Aedes mosquito from the affected area, a finding quite inconsistent with past outbreaks. The delayed reporting of the outbreak with the consequent delay in conducting the investigation during the dry winter months of November and December possibly prevented us from detecting the vector. Given the role of environmental variables on Aedes albopictus and on the pathogen transmissibility, we believe that transmission likely stopped due to changes in weather that constrained Aedes mosquito populations during this outbreak.[Aedes larvae by December, and other outbreaks in Bangladesh have also stopped abruptly around the months of November and December.[Aedes albopictus species.[Aedes albopictus were most likely responsible for transmission,[The first recognized outbreak in Chapainababganj district in 2008 predominantly affected Hindu potters and had limited geographic spread. The outbreak was reportedly precipitated by the high concentration of pottery. During t pottery., 14, 56 pottery., 33 despoutbreak., 58 We wDecember., 33, 34 species. Another A major limitation of our investigation was that the suspect cases that presented for clinical assessment and blood collection were unlikely representative of the entire affected population. We expect that cases with severe and/or persistent symptoms were more likely to come to the clinic compared to milder cases or patients who had recovered, so our clinical descriptions of serologically confirmed cases were likely biased towards severe presentations. However, since almost half of the cases had already recovered from clinical illness during the clinical survey, we also captured some less serious disease. Given that an evaluation of the sensitivity and specificity of clinical criteria for CHIKV infection identified the syndrome combining fever and polyarthralgias to allow for the correct classification of 87% of those who had serologically confirmed CHIKV infections, our caseAedes populations.Though no recent community seroprevalence study of CHIKV has been published from Bangladesh, a post outbreak sero-survey conducted in selected outbreak affected communities under publication by the author group as well as a 1995 cross-sectional survey carried out in the neighbouring city of Calcutta, India indicated that the level of previous exposure to Chikungunya infection in the country remained low. FurthermAedes mosquitoes in the future may help provide important insight into emergence of epidemic strains in Bangladesh. Effective mosquito control using a comprehensive and integrated pest management approach targeted at every life stage of a mosquito could reduce the risk of CHIKV dissemination.[Population-based seroprevalence and risk factor surveys could help describe the true extent of previous circulation of this virus and identify factors that might put some communities at higher risk than others for outbreaks.

However this diversity remains unexploited and effective approaches are required to investigate the benefits that unadapted genomes could bring to crop improved resilience. In the present study, a set of Recombinant Chromosome Substitution Lines (RCSLs) derived from an elite barley cultivar \u2018Harrington\u2019 as the recurrent parent, and a wild barley accession from the Fertile Crescent \u2018Caesarea 26\u201324\u2019, as the donor parent have been utilised in field and controlled conditions to examine the contribution of wild barley genome as a source of novel allelic variation for the cultivated barley genepool.Twenty-eight RCSLs which were selected to represent the entire genome of the wild barley accession, were genotyped using the 9\u2009K iSelect SNP markers and phenotyped for a range of morphological, developmental and agronomic traits in 2 years using a rain-out shelter with four replicates and three water treatments. Data were analysed for marker traits associations using a mixed model approach.We identified lines that differ significantly from the elite parent for both qualitative and quantitative traits across growing seasons and water regimes. The detailed genotypic characterisation of the lines for over 1800 polymorphic SNP markers and the design of a mixed model analysis identified chromosomal regions associated with yield related traits where the wild barley allele had a positive response increasing grain weight and size. In addition, variation for qualitative characters, such as the presence of cuticle waxes on the developing spikes, was associated with the wild barley introgressions. Despite the coarse location of the QTLs, interesting candidate genes for the major marker-trait associations were identified using the recently released barley genome assembly.This study has highlighted the role of exotic germplasm to contribute novel allelic variation by using an optimised experimental approach focused on an exotic genetic library. The results obtained constitute a step forward to the development of more tolerant and resilient varieties.The online version of this article (10.1186/s12870-018-1527-7) contains supplementary material, which is available to authorized users. Breeding programmes have successfully increased yield and quality traits of major cereals including barley , 2. HoweHordeum are preserved in gene banks worldwide, second only to rice and wheat (FAO 2010) and provide an enormous potential resource for allele mining. There have been many descriptive and comparative studies examining diversity in wild and landrace barleys, but few examples utilising the allelic diversity have been reported ) and the recurrent parent ([Hv]) alleles obtained for the significant peak region were used to calculate the relative contribution (RP) of the exotic parent alleles on the trait performance as follows:The Best Linear Unbiased Estimates (BLUEs) for each trait for the donor ([2) were used to identify possible putative candidate genes underlying the predicted phenotypic variation. In this case the number of genes in the targeted regions was first estimated by looking at the physical position of the iSelect SNP markers in the newly released barley genome assembly [The position of major determinant genes related to plant phenology and morphology was estimated from previous studies and public gene databases to support the results obtained from this analysis. Additionally, some genomic regions accounting for a significantly large proportion of a trait\u2019s variance of the k-th principal component axis, \u03b3ik and \u03b4jk are the genotype and the environment scores (eigenvectors) for the k-th principal component axis, \u03c1ij is the interaction residual and \u03b5ijk is the random error.Values for yield (DY) and grain weight (TGW) for each of the RCSLs were used to investigate the effect of the exotic genome in the performance and stability of the crop across the environmental conditions imposed in the field. Genotype by environment (GE) interaction was studied by means of an additive main effects and multiplicative interaction model (AMMI) for which six environments were defined as the combination of growing season and water treatment. Using this method, the overall variation observed for yield traits such as dry yield and thousand grain weight was partitioned into genotype main effects, environment main effects and GE interaction . The modAs a result, the interaction principal components generated (IPCA1 and IPCA2) are used to graphically summarise (biplots) the GE variation observed. The AMMI2 biplot uses the genotypes and environments scores for the first two IPCA components (IPCA1 on the X-axes and IPCA2 on the Y-axes) giving information about the GE patterns observed. Genotypes with IPCA scores close to zero are more stable or widely adapted to the tested environments whereas specific adaptation of the genotypes is determined by the length of the orthogonal projection of the genotype points onto the environmental vectors. In addition, the AMMI1 biplot tests the genotypes yield potential and stability simultaneously by plotting in the same diagram the average yields (X-axes) and the first dimension measure of GE interaction (IPCA1) for both genotypes and environments (Y-axes).

They experience caregiving stress that negatively influences their mental health while struggling with limited social support from peers, and minimal respite care and community resources.

This qualitative study explored Korean custodial grandparents\u2019 experiences of raising grandchildren and cultural meanings of multigenerational caregiving. Using a phenomenological approach, semi-structured interviews with 23 custodial grandparents were conducted from December 2018- January 2019 in two urban and three rural places in Korea. Among the grandparents, five were grandfathers. The mean age of the grandparents was 72 years old (range: 61-82), and the mean age of their grandchildren was 13 years old (range: 1-21). On average, the grandparents had raised 1.5 grandchildren (range: 1-3) for 11 years (range: 1.5-20).

Quasispecies diversity was higher in granulomas than in recovered infectious iVDRVs. Growth properties of iVDRVs were assessed in WI-38 fibroblast cultures. None of the iVDRV isolates showed complete reversion to wild type phenotype but the replicative and persistence characteristics of iVDRVs were different from those of the RA27/3 vaccine strain, making predictions of iVDRV transmissibility and teratogenicity difficult. However, detection of iVDRV RNA in nasopharyngeal specimen and poor neutralization of some iVDRV strains by sera from vaccinated persons suggests possible public health risks associated with iVDRV carriers. Detection of IgM antibody to RV in sera of two out of three patients may be a marker of virus persistence, potentially useful for identifying patients with iVDRV before development of lesions. Studies of the evolutionary dynamics of iVDRV during persistence will contribute to development of infection control strategies and antiviral therapies.Rubella viruses (RV) have been found in an association with granulomas in children with primary immune deficiencies (PID). Here, we report the recovery and characterization of infectious immunodeficiency-related vaccine-derived rubella viruses (iVDRV) from diagnostic skin biopsies of four patients. Sequence evolution within PID hosts was studied by comparison of the complete genomic sequences of the iVDRVs with the genome of the vaccine virus RA27/3. The degree of divergence of each iVDRV correlated with the duration of persistence indicating continuous intrahost evolution. The evolution rates for synonymous and nonsynonymous substitutions were estimated to be 5.7 x 10 Primary immunodeficiency diseases (PID) are caused by genetic defects and lead to serious problems including chronic granulomas of inflammatory cells), sometimes lasting for decades and sometimes leading to severe ulcers. Initial reports (2014\u20132016), including our report of a blinded study using ultrasensitive virus detection in biopsies, proved the association between granuloma of the skin in PID patients and rubella virus. The viruses in these reports and the current report were derived from a widely used vaccine strain of the rubella virus. Work reported here shows that these vaccine-derived viruses are biologically different from the vaccine virus and that their genomes have changed. Genomic changes could be analyzed largely because the exact sequence of starting vaccine virus genome was known. These genomic differences are likely generated via mechanisms similar to those occurring during normal circulation of wild type rubella. We present data that newly recognized mechanisms for generation of sequence diversity in viruses (because of cellular deaminases) likely occurs in the generation of these vaccine-derived rubella viruses. Thousands of PID patients in the United States are likely shedding these vaccine-derived rubella viruses. Our work presented here characterizing viruses in diagnostic specimens highlights at least two areas where insufficient work has been done: 1) research on the properties of rubella virus (limited understanding of the antibody binding sites on the virus); 2) controlled research studies to assess the public health impact of viruses in populations with high immunity.

In addition to features like area, perimeter andeccentricity, other features like centroid, diameter and pixel meanintensity have been extracted during feature extraction. Theclassification module follows this where distinction between benignand malignant tumors based on CT scan images is established.Extracted features are used as training features and thecorresponding trained model is generated for the classificationfollowed by model evaluation for detection and classification withimproved accuracy, specificity and sensitivity.The salient features of the method includes (1) image preprocessingby using filtering techniques and it smoothes the image andremoves speckle noise; (2) It segments the cancer nodule from theCT scan image. The segmentation method separates and identifiesthe touching objects in the image. This feature helps in propersegmentation of cancer nodules when it is touching to other falsenodules. (3) Features extraction where features like area, perimeter,centroid, diameter, eccentricity and mean intensity are extractedfrom the image. These features are used as training features todevelop the classifier; and (4) The classification module classifiesthe detected nodule as malignant or benign by using the trainedclassification method.Strengths of the method includes: (1) The improved accuracy ofcancer nodule detection; (2) classifies the detected lung cancer asmalignant or benign; and (3) Removes the noises that create falsedetection of cancer.We describe and discuss the application of a Computer-AidedDiagnosis (CAD) system using Computed-Tomography (CT)images to help in the early diagnosis of lung cancer .

They are in particular involved in the control of pain perception and reward properties. They are also the primary molecular target of opioid drugs and mediate their beneficial analgesic effects, euphoric properties as well as negative side effects such as tolerance and physical dependence. Importantly, mu opioid receptors can physically associate with another receptor to form a novel entity called heteromer that exhibits specific ligand binding, signaling, and trafficking properties. As reviewed here, The mu opioid (mu) receptor is a G protein-coupled receptor (GPCR) that neuromodulates several physiological functions, in particular nociception , and/or disruption of physical contact by an interfering peptide. The use of interfering peptide and/or mice deficient for one receptor also significantly contributed to demonstrate the specificity of the functional changes associated with heteromer formation and to establish a causal link with behavioral outputs. In native tissue, the mu receptor heteromerizes with the delta opioid (delta) or kappa opioid (kappa) receptors or with the non-opioid receptors ORL1, cannabinoid CB1, galanin Gal1, adrenergic \u03b12a, somatostatin sst2, dopamine D1, chemokine CCR5, and vasopressin V1b.

Higher levels of mu-\u03b1Interactions between mu and somatostatin receptors have been postulated to influence tumor cell growth (Hatzoglou et al., The bivalent ligand MDAN-21 composed of the mu agonist oxymorphone and the delta antagonist naltrindole tethered by a 21 amino acid long linker was developed to selectively target mu-delta heteromers (Daniels et al., More recently, the bivalent ligand MCC22 linking the mu agonist oxymorphone to the CCR5 antagonist TAK220 has been proposed to inhibit inflammatory and neuropathic pain by targeting mu-CCR5 heteromers (Akg\u00fcn et al., A major limitation to the therapeutic use of bivalent ligands is their poor capacity to cross the blood brain barrier (Le Naour et al., in vivo and their functional interactions addressed in a handful of tissue or brain areas. Moreover, heteromer expression is dynamically regulated depending on physiopathological conditions. No doubt that both novel functions and receptor pairs will be uncovered in the future, which further emphasizes their potential as innovative therapeutic targets.Our current appreciation of the role of mu heteromer is still in its infancy and their contribution to mu receptor-dependent behavior likely underestimated. So far, physical proximity has only been validated for a limited number of receptor pairs All authors listed have made a substantial, direct and intellectual contribution to the work, and approved it for publication.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "Augmented reality (AR), superimposing digital assets onto the real-world \u2014offers a paradigm shift in delivering immersive interventions for aging adults.

The chosen study area is the third infected Province with TB in South Africa.Results: A total of nine polyherbal preparations were collected. Information on the parts of the plant used, mode of preparation and the dosage used were documented. In total, the herbs belong to 20 families of which Apiaceae, Liliaceae, Strychnaceae, Rutaceae and Hypoxidaceae are the most prominent. However, members of Apiaceae were commonly mentioned for the preparation of the remedies. The two most frequently used plants were Allium sativum L. (Liliaceae) and Strychnos decussata (Pappe) Gilg.

The therapeutic claims made on medicinal plants used for the preparations are well supported by the literature, with many of the species having antimicrobial properties. Mycobacterium tuberculosis has remained one of the most prevalent causes of mortality in developing nations, especially in the Asian and African continents. The disease remains a big problem in these countries probably due to inadequate means for the management and treatment of the disease. According to World Health Organization (2002), about 95% of the approximately eight million cases of TB occur each year in Africa having the highest incidence. However, South Africa is the third highest incidence country after India and China with about 80% of the population infected with the disease. This rate has increased by 400% over the past 15 years most especially among the people living with human immuno-deficiency virus (HIV) caused by M. tuberculosis to commonly prescribed antimicrobials has made people fall back on herbal medicines for various therapeutic purposes .

The aims of the study are to (1) develop a cultural adaptation of an evidence-based TGC intervention that consists of phone genetic counseling and a booklet, (2) evaluate the impact of TGC Versus Usual Care, and (3) explore the communication patterns in TGC and genetic counseling sessions with an interpreter. METHODS/STUDY POPULATION: We are conducting a 2-phase, mixed methods study. In Phase I we will develop a cultural adaption of an evidence-based intervention (TGC) for high-risk Latina breast cancer survivors using the Learner Verification and Revision Framework (n=15). In Phase II we will use a cluster randomized design with four community sites randomized to Spanish TGC (n=2 sites) or usual care (n=2 sites) . The primary outcome is genetic counseling uptake. Among women who receive genetic counseling either through TGC (n~30) or with an interpreter (n~15), we will assess counseling quality by reviewing 20 randomly selected audiotaped sessions . We will evaluate women\u2019s HBOC knowledge and satisfaction with counseling. Communication processes and outcomes will be assessed using gold standard RIAS quantitative coding system and qualitative discourse analysis. RESULTS/ANTICIPATED RESULTS: We elicited input from transdisciplinary team members to develop an initial adaptation of a TGC print booklet and intervention protocol for use with high-risk Latina breast cancer survivors with limited English proficiency. The booklet contains low-literacy information about HBOC, risk factors, pros and cons of testing, and management strategies. Based on these materials and prior work, we anticipate TGC will consist of one 1 hour or less TGC session by phone. Participants interested in pursuing testing will receive a saliva kit and will participate in a second TGC session (30 min) to discuss test results and management options. DISCUSSION/SIGNIFICANCE OF IMPACT: Given access barriers and the shortage of Spanish-speaking genetic counselors, adapting and translating TGC intervention is a promising strategy that could reduce disparities by broadening the reach and accessibility to genetic counseling while enhancing the quality of the service for Latinas with limited English proficiency."} +{"text": "Background: Death certificate inaccuracy increases at older ages. The Long Life Family Study (LLFS) utilizes a physician adjudication committee to review the death certificate, medical records and a family narrative about cause of death. We report here the adjudication process and the prevalent underlying causes of death for a subsample of those who have died so far. Methods: We first describe the adjudication process. There were ~1,250 deaths in LLFS. We report underlying causes of death for a subset of proband generation subjects enrolled and evaluated by two LLFS study centers. Results: As of May 2019, we have adjudicated 190 deaths . Mean age 95 years (range 81-105 years). Top 5 causes of death for men: cancer (13%), coronary heart disease , dementia (13%), \"other\" (11%) and \"unknown\" (9%) and for women: dementia (21%), valvular heart disease (14%), coronary heart disease (12%), unknown (12%) and other (9%). Rate of death due to dementia was greater in women compared to men . Conclusions: In this pilot study, a significantly greater proportion of women died due to dementia compared to men. At least some portion of this difference may be due to the observation that women are known to survive chronic aging-related diseases more than men and thus have a greater opportunity to die from dementia at advanced ages.

Depression education was provided to 15 housing staff and 78 older adult residents. A total of 34 depression screens were completed ; further evaluation of symptoms was indicated for 59% (n=20) of those screened. Seventeen of the 20 residents accepted a recommendation for a referral to supportive counseling; 3 declined. The average PHQ-9 score was 8.45 . Referrals to case management and house calls (n=4) were also made. Feedback from both housing residents and staff was positive and the project team learned valuable lessons about serving older adults in congregate living settings which has informed other programming. The project was successful in providing education, screening and referrals to residents who might not otherwise have access to specialized geriatric behavioral health interventions."} +{"text": "We examine trait and state subjective aging as antecedents of control beliefs in older adults with a daily diary design.

A sample of 1645 older adults using multi-stage sampling method in Shanghai were randomly selected in this cross-sectional study. Frailty operationalized as Cardiovascular Health Study criteria and PNSC measured as Neighborhood Cohesion Scale were independently associated with basic and instrumental activities of daily living disability. A significant interaction of frailty and PNSC on disability =4.31, P=.014) was found, using a two-way analysis of covariance (ANCOVA). Compared to robust individuals with high PNSC, pre-frailty with high PNSC was not significantly associated with disability while pre-frailty with low PNSC was associated with approximate 4-fold increased prevalence of disability . Frailty with high PNSC was associated with higher likelihood of disability and frail individuals with low PNSC stood out with 10-fold increased prevalence of disability . All analyses were controlled for demographical and clinical covariates. Our results suggest high level of social cohesion serves as a buffer against the impact of physical frailty on functional disability. These findings notably imply to the development of interventions for older frail adults from the neighborhood perspective."} +{"text": "Plants grow continuously, forming new meristem-derived organs and tissues throughout their post-embryonic life.

Eligible studies examined associations between occupational mobility and at least one measure of chronic illness among adults aged 50 years or above. Occupational disruptions were reviewed as special cases of occupational mobility. Results: Downward occupational mobility and mid-life occupational disruptions have been consistently shown to predict higher risk of chronic illness in older adults. Several potential mechanisms were identified from the literature: (1) health behaviors, including dietary practices and alcohol consumption; (2) psychosocial factors, including stress, stigma, job control, job demands, and job satisfaction; (3) economic factors, including financial incentives or constraints; and (4) other individual characteristics, including personality traits and coping skills. There is also evidence that the timing of job mobility and the duration of (each) occupation modify the association between occupational mobility and health in late life.

One level of control on the activity of MAPKs is through their negative regulators, MAPK phosphatases (MKPs). Therefore, MKPs also play an integrative role for plants responding to diverse environmental stimulus; but the mechanism(s) by which these phosphatases contribute to specific signals remains largely unknown. In this review, we summarize recent advances in characterizing the biological functions of a sub-class of MKPs, dual-specificity phosphatases (DSPs), ranging from controlling plant growth and development to modulating stress adaptation. We also discuss putative regulatory mechanisms of DSP-type MKPs, which plants may use to control the correct level of responses at the right place and time. We highlight insights into potential regulation of cross-talk between different signaling pathways, facilitating the development of strategies for targeting such cross-talk and to help improve plant resistance against adverse environmental conditions without affecting the growth and development. To rapidly adapt to various environmental challenges, plants need to balance diverse signal inputs which involves crosstalk between different signaling pathways. A common strategy for integrating these signals is through use of shared components, including mitogen-activated protein kinase (MAPK) cascades that play essential roles in signal transduction and amplification for many distinct cellular responses. MAPK cascade modules are conserved in all eukaryotes and consist of three kinase components: MAPK kinase kinases (MAPKKKs) phosphorylate dual-specificity MAPK kinases (MAPKKs), which then phosphorylate and activate the terminal MAPKs in a Thr-X-Tyr activation loop and metal-dependent protein phosphatases (PPMs), which are serine/threonine phosphatases, and tyrosine phosphatases (PTPs) Shi, . RepresePTPs are biochemically distinct protein phosphatases and include tyrosine specific phosphatases and dual-specificity (Ser/Thr and Tyr) phosphatases (DSPs) phosphatases (DSPs) belong to a subfamily of the tyrosine phosphatases (PTPs) that can dephosphorylate both phosphoserine/phosphothreonine and phosphotyrosine within the activation loop of MAPKs , synthetic auxins and auxin transport inhibitors and PDR9 genes were characterized, and these two genes encode ABC transporters implicated in the efflux of synthetic auxins mutants, which display a defect in a microtubule-associated protein in the putative kinase interaction motif (KIM) of MAPKs such that the mutation might interfere with interactions with the target MAPK(s). Therefore, it has been proposed that PHS1 may regulate multiple MAPKs; and a subset of its target kinases may be involved in the organization of cortical microtubules. To further investigate the mechanism underlying microtubule regulation, a screen for PHS1-interacting MAPKs was performed; and MPK12 and MPK18 were identified by yeast two-hybrid assays was expressed in the background of phs1-5 to examine if the phosphatase-dead form of PHS1 functions as a dominant-negative microtubule destabilizer which acts in the apical meristem to induce floral identity genes treatment, including activation of MPK6 and MPK3, production of reactive oxygen species (ROS), accumulation of a subset of PAMP-regulated transcripts, and inhibition of seedling growth DC3000 (hereafter referred to as DC3000) dephosphorylates phospho-MPK3 and phospho-MPK6 ibr5-7 suppresses the chilling-induced defense responses of chs3-1 to stabilize CHS3 protein, thus increasing the accumulation of CHS3 . IBR5 interacts with and promotes the accumulation of SNC1 and DC3000 (avrRps4) proteins. IBR5 plays a positive role in regulating R protein CHS3, as evidenced by that mutation of mkp1 mutant results in hypersensitivity to various genotoxic stresses , suggesting that MKP1 plays essential roles in genotoxic stress relief -induced nitric oxide (NO) production in guard cells , superoxide anion O2\u2212 and hydrogen peroxide levels in the TMKP1 transgenic seedlings and downregulation of two ABA-repressed genes , including hydrogen peroxide (H2O2), hydroxyl radical (HO.), singlet oxygen (1O2) and superoxide anion (mkp2 mutants was more severely inhibited by the oxidative agent methyl-viologen (MV) compared to wild type plants , mkp1 mutants produced more ROS than in wild type plants are generated from partial reduction of oxygen treatments , contributing to differences in amplitude and duration of signaling. Many examples have shown that the phosphatase activity of MKPs can be regulated by post-translational modification. Mammalian MKP1s (not an orthologue of plant MKP1s) and yeast Msg5 are phosphorylated by their own substrates MAPKs, and phosphorylation regulates not only the activities but also the abundance of the phosphatases, establishing an efficient negative feedback loop ; and phosphorylation of TMKP1 is required for the interaction , which was mainly localized in cytoplasm, the localization of both MAPKs also changed to the cytoplasm substrates but decreases phosphatase activity on the phosphotyrosine of myelin basic protein (MBP), suggesting that calmodulin differentially regulates substrate specificity but not CaMBDII mutant (W678R) can be activated by CaM, which indicates that CaMBDII plays a more important role than CaMBDI for the regulation of MKP1 binding proteins, where CaM is a CaThis review summarizes current knowledge of the roles of MKPs in multiple signaling pathways. MKPs are involved in many aspects of a plant's life cycle, including growth and development as well as the adaption to various biotic and abiotic stresses. As different signaling pathways integrate through MKPs, it is critical for MKPs to undergo precise regulation to generate correct biological outcomes. These investigations of regulatory mechanisms have provided insights into putative mechanisms that might explain how the phosphatases assist in producing specific signals. The potential combinatorial complexity of different transcriptional/post-transcriptional regulations, differential localization affecting subcellular pools of MAPKs, and the possibility to integrate information from other pathways may have profound effects on organizing the amplitude and duration of targeted kinases.As important as the MKPs appear to be, most of our knowledge regarding their functions is limited to their roles in negatively regulating MAPK signaling, and few other potential upstream and/or downstream targets have yet to be characterized. Genome-wide analyses will certainly facilitate a better understanding of MKPs-mediated signaling pathways by identification of both molecular players in the pathways as well as additional putative MKP targets. A better understanding of how plants coordinate and balance different signaling pathways in response to diverse environmental stimuli could lead to more rationally designed strategies for improving crop yield under changing environmental conditions.

It is now well-established that light is the main environmental element that synchronizes circadian rhythms. An appropriate lighting condition can be considered as a non-pharmacological solution to improve the sleep quality of individuals and consequently their overall health and well-being. The present study investigates the effectiveness of two proposed whole-day lighting interventions (L1 and L2) applied by Tunable White Lighting Technology (TWLT) on sleep quality and cognitive performance in older adults. Both lighting interventions provide a high illuminance level (500 lux) in the morning and then the illumination is dimmed gradually throughout the day and reached 100 lux in the evening. However, while L1 offers a constant Correlated Color Temperature (CCT) of 2700K, during the L2 intervention, the CCT is changing in the range of 6500K \u2013 2700K from morning towards evening. Fifteen healthy older adults participated in a 41-day counterbalanced crossover study. Participants were exposed to each lighting condition for 9 days.

Besides genetic material DNA wrapped around histone octamer, chromatin structure determined by chromatin modification including DNA methylation, histone modification and chromatin remodeling also contributes greatly to the regulation of gene expression. In this review, we summarize the current progresses on the molecular mechanisms of chromatin modification in regulating root development. The root system constitutes the underground world of a plant, and it takes charge of nutrient and water supply for the whole plant under normal and stress environments. The developmental status of the root system directly determines the plant survival and performance of leaves, stems, flowers, fruits, and seeds, which are closely related to animal and human life. Compared with the aerial part, the building unit of a root system is simple and mainly consists of primary and lateral roots (LRs) without substantial difference in appearance. An intact root system is derived from the tiny root apical meristem (RAM). Proliferation and differentiation of RAM give rise to different types of root cells and tissues.Transcription factors combined with phytohormones, small signaling molecules, and miRNAs play an essential role in regulating the stem cell fate and RAM maintenance during root development . For instance, active marker histone acetylation and repressive marker histone deacetylation are catalyzed by histone acetyltransferases (HATs) and histone deacetylases (HDACs), respectively homologs , three Su(z)12 homologs , a single ESC homolog (FIE), and five p55 homologs (MSI1\u2013MSI5). PRC1 core subunits consist of two RING1 homologs (AtRING1a/b), three Psc homologs (AtBMI1a/b/c), a Pc equivalent (LHP1), and a plant-specific component EMF1, without the Ph counterpart proteins associated with repressive genes and the trithorax group (TrxG) proteins associated with active genes and atrichoblast/non-hair cell (N) in an alternative arrangement, providing a well-characterized system for studying the relationship between root epidermal cell fate decision and positional cue from underlying cortical cells /IAA14 (mIAA14) protein with enhanced inhibiting capacity on the downstream targets ARF7/19 , which is a core component of several HDAC corepressor complexes , resulting in formation of decreased CDF4 protein gradient from differentiated columella, CSCs to QC, which is opposite to the WOX5 protein gradient and permits the exit of stem cell descendants from the stem cell state in roots family ; it downregulates auxin maxima in roots, thereby inhibiting the establishment of founder cells during LR initiation display a certain proportion of \u201cpkl-root\u201d phenotype , FUSCA3 (FUS3), LEAFY COTYLEDON2 (LEC2), and LEAFY COTYLEDON1 (LEC1) and H3K4me3 through the CW domain or PHD domain and H3K27me3 through the PHD domain and reduction in levels of gene repression mark H3K27me3 in seedling and cysteine and tryptophan residue-containing domain (CW), which usually act as histone code reader modules, and the ethylene-responsive element binding factor-associated amphiphilic repression (EAR) domain that functions as a repressive motif to recruit corepressors but is enhanced by GA biosynthesis inhibitor paclobutrazol can recognize the active mark H3K4me3 through the PHD-domain and interact with the RAWUL domain of PRC1 RING-finger proteins through the PAL domain and many additional types pathway by directly targeting the chromatin of several PIN genes and affecting auxin distribution.

Best Practice Caregiving is a newly launched website where professionals can get detailed information about these programs. Data collected to develop Best Practice Caregiving are analyzed for a sample of 42 evidence-based dementia caregiving programs to describe similarities and differences among programs including gaps in assistance available from these programs.

T2DM patients with HF have a higher risk of mortality and hospitalization for HF than HF patients without T2DM. Therefore, there is an increasing necessity to find new diagnostic instruments and treatments to improve clinical outcomes in T2DM subjects with HF , current research demonstrate many additional important and possibly beneficial direct effects of these drugs on endothelial cells and cardiomyocytes. SGLT2 inhibitors can normalize elevated sodium and calcium levels in cardiomyocytes through inhibition of the cardiac sodium-hydrogen exchanger, improve vascular function and activate anti-oxidant systems and intracellular stress signals such as AMPK and reduce inflammatory pathways. Further research will have to demonstrate to what extent these cellular cardiac mechanisms contribute to the large beneficial effects of SGLT2i's in clinical trials. Despa then goes on to describe that sodium is often increased in the failing and diabetic cardiac cell. Elevated intracellular sodium can then cause oxidative stress and augments the sarcoplasmic reticulum Ca2+ leak, thus amplifying the risk for arrhythmias and promoting heart dysfunction. Alterations in Na+ extrusion and/or Na+ uptake that underlie the [Na+]i increase in heart failure and diabetes are discussed, and emphasis is placed on the emerging role of Na+ -glucose cotransporters in the diabetic heart. Doliba et al. subsequently demonstrate the functional and energetics consequences of elevated sodium in the diabetic cardiomyocyte in their pioneering studies in this field. Their work clearly indicates that raising sodium in the cardiac cell will directly result in impaired mitochondrial function, possibly explaining the often observed energetic problems in the diabetic heart. These reviews all point to the importance of ionic homeostasis and disturbances in the setting of diabetic cardiomyopathy, cardiac arrhythmias, and the elevated incidence of heart failure in T2DM patients.Liu et al. evaluated the clinical effects of Black garlic in patients with ischemic heart failure. They found that black garlic treatment improved cardiac function in terms of left ventricular ejection fraction and the scores of quality of life (QOL) and decreased circulating BNP precursor N-terminal (Nt-proBNP) by increasing antioxidant levels.The article by Koyani et al. studied the effects of saxagliptin and sitagliptin (anti-hyperglycemic drugs that have been shown to inhibit dipeptidyl peptidase 4 -DPP4) in mouse ventricular cardiomyocytes. The authors showed that saxagliptin (but not sitagliptin) impaired Ca2+ transient relaxation and prolonged action potential duration in cardiomyocytes. They suggested that these results are linked to saxagliptin-DPP9 interaction and following impairment in Ca2+/calmodulin- dependent protein kinase II (CaMKII)- phospholamban (PLB) and protein kinase C (PKC) signaling.Trotta et al. investigated the anti-hypertrophic effect of the melanocortin receptor 5 (MC5R) stimulation in cardiomyocytes exposed to high glucose. The authors showed that MC5R agonists increased viability and reduced total protein in cell stimulated with high glucose via reduced GLUT1/GLUT4 ratio at the plasma membrane and increased intracellular phosphoinositide 3-kinase (PI3K) activity. In addition, MC5R stimulation showed beneficial effects on cardiac function and hypertrophy paralleled by significantly reduced blood glucose levels in a rat model of diabetes (streptozotocin-induced).We have arrived at exciting times in the world of diabetes and heart failure. At last, several novel antidiabetic drugs have shown large cardiovascular benefits in T2DM patients. Understanding the causal mechanism of these effects are now crucial in order to further our understanding of the interaction between diabetes and heart failure, possibly also offering new therapeutic strategies to combat heart failure in the absence of diabetes.All authors listed have made a substantial, direct and intellectual contribution to the work, and approved it for publication.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "This study is a secondary analysis of the Outcome and Assessment Information Set (OASIS) and administrative billing records of 6,153 adults \u2265 65 years old who received home health (HH) from a not-for-profit HH agency in upstate New York in CY 2017.

Modalities to achieve therapeutic effects have utilized virus-mediated transfer of wild type genes and small interfering ribonucleic acids; systemic and focal administration of antisense oligonucleotides (ASO) and designer small molecules; and lipid-mediated transfer of Cas 9 ribonucleoprotein (RNP) complexes. This work has established that gene or drug administration to the structurally and functionally immature, early neonatal mouse inner ear prior to hearing onset is a prerequisite for the most robust therapeutic responses. These observations may have significant implications for translating mouse inner ear gene therapies to patients. The human fetus hears by gestational week 19, suggesting that a corollary window of therapeutic efficacy closes early in the second trimester of pregnancy. We hypothesize that fetal therapeutics deployed prior to hearing onset may be the most effective approach to preemptively manage genetic mutations that cause deafness and vestibular dysfunction. We assert that gene therapy studies in higher vertebrate model systems with fetal hearing onset and a comparable acoustic range and sensitivity to that of humans are an essential step to safely and effectively translate murine gene therapies to the clinic. Gene replacement, augmentation, knock down and knock out strategies have been elucidated to ameliorate the effects of deleterious mutations that cause hearing loss and vestibular dysfunction in mouse models of human inner ear disease. Table Vglut3 knockout mouse after round window membrane inoculation at postnatal day 1\u20133 , compound action potentials (CAP) and acoustic startle -mediated gene transfer to the sensory epithelium by delivery through the round window membrane introduces a cryptic splice site in exon 3 of the PDZ domain scaffolding protein, harmonin and generates a frameshift with premature stop codon. The splicing machinery strongly prefers the cryptic splice site though wild type splicing is not precluded. The Ush1c c.G216A knock-in mouse accurately models the hearing and vestibular abnormalities seen in USH1C patients to interfere with pre-mRNA splicing from the cryptic splice site and enhance wild type splicing. ASO therapy restored functionally relevant levels of protein expression, improved hair cell survival, rescued ABR thresholds at low and intermediate frequencies, and corrected vestibular dysfunction .

The The literature discussed thus far demonstrates that AAV-, ASO- and CRISPR/Cas9 RNP-based therapies achieve maximal benefit for recessively and dominantly inherited forms of deafness and vestibular dysfunction when initiated from P0\u2013P5. Furthermore, initiating therapeutic strategies after P5 shows reduced efficacy or the elimination of therapeutic benefit entirely Table .

An alternative model system was developed due to the difficulty in obtaining sufficient numbers of mutant mice for extensive analysis. A plasmid encoding four short hairpin RNAs (shRNAs) against Cx-30 was electroporated into wild type mice at E11.5 that knocked down Cx-30, elevated ABR thresholds to over 90 dB SPL from 4 KHz to 20 KHz, and depleted the EP. Co-electroporation of a shRNA-resistant sequence encoding Cx-30 along with the shRNAs against wild type Cx-30 in wild type mice resulted in improved ABR thresholds and EP is a nuclear-localized, long noncoding RNA robustly expressed in a diverse array of tissues that is nonessential for mouse pre- and postnatal development (Zhang et al., MALAT1 RNA effectively reduced expression in most mouse tissues analyzed (Wheeler et al., MALAT1 ASO into the E13-E13.5 mouse amniotic cavity reduced MALAT1 RNA abundance in the inner ear through P15 establishing that the ASO gains entry into embryonic tissues and exerts its bioactive effects through the second postnatal week (Depreux et al., Ush1c mutant mice generated correctly spliced harmonin RNA in the inner ear at P22 (Depreux et al., While direct injection of bioactive reagents into the developing inner ear is formally a plausible gene therapy strategy, it is unlikely that targeted injections will be conducted into the human otic vesicle which first forms by GA 6 not long after most pregnancies are first verified (Streeter, The therapeutic modulation of inner ear gene expression by systemic and focal injections of bioactive reagents has defined authentic gene therapy strategies in mouse models of hearing loss and vestibular dysfunction. The literature establishes that therapeutic intervention in the functionally immature mouse inner ear by 5 days postnatal age leads to optimal recovery of hearing and balance. This early neonatal window of therapeutic efficacy holds irrespective of the molecular strategy, delivery modality, or viral vector serotype deployed. Moreover, a corollary prenatal window of therapeutic efficacy in humans is predicted to close by 19 weeks of GA before the onset of fetal hearing. The efficacy of fetal gene therapy to preemptively correct deleterious genetic mutations in the organogenesis stage mouse embryo before the onset of inner ear disease is an emerging research focus that has promising potential. The process of defining and validating fetal and postnatal gene therapies will be critically enhanced by rigorous evaluation in higher vertebrate model systems in which the fetal onset of hearing is a defining feature.LW, JK and JB identified the need for a comprehensive review of the literature on gene therapy to treat inner ear disease.

Data storage enables analysis of cancer incidence and mortality by type of cancer (classified according to ICD-10), age, sex and voivodeship, as well as creating custom reports. The average completeness of the Cancer Registry in Poland has been continuously improving and is currently estimated to be 94% .The cancer risk in each of 16 Polish voivodeships was calculated as incidence rates and expressed as the number of newly registered cases of cancer in 2014 per a population of 100,000. The absolute numbers of newly registered cases of lung, breast and colon cancer in Poland by voivodeships were retrieved from the Polish National Cancer Registry (NCR). NCR is a principal data source for cancer incidence in the Polish population. Healthcare providers are legally obliged to provide annual reports to NCR about every case of cancer diagnosed within the Polish population. Principles of data collecting and institutions responsible for cancer registries in Poland are specified in two acts: the Act on Public Statistics and the Act on the Health Care Information System and an ordinance issued on the basis of the said Act. The unit responsible for the registry is the National Cancer Registration Office, which is an organizational unit of the Cancer Centre and Institute of Oncology. New cases of cancer are collected via specific cancer registration forms (MZ/N-1a form) and each voivodeship is obliged to deliver the data to a shared NCR database. The data is validated using rules enforced to the system. An online database is available at Area-based socioeconomic measurements were retrieved from the Polish Social Cohesion Survey for the year 2015 .

After sex, age and completeness of data adjustment the correlations between breast cancer incidence and socioeconomic variables were not substantially modified, only correlation with income poverty became statistically insignificant.The risk of breast cancer was statistically significantly negatively related to: (1) income poverty . Adjustment for age, sex and data completeness produced fairly similar coefficients.The only statistically relevant for colon cancer was a negative correlation between colon cancer risk and high level of friend- and neighbour-based social capital imply that a low income situation (determined by revenue) does not necessarily signify other poverty forms. Time factor is, therefore, extremely important, because poor living conditions and budget difficulties result from unfavourable income situation continuing for a longer period. The strong relationship with material situation observed for association-based capital and social isolation suggests a coexistence of these factors. All of these determinants were correlated with lung cancer risk. However, the question whether poverty caused social isolation and low level of association-based social capital, or if, conversely, social isolation and low level of association-based capital caused poverty, is still to be answered.These results should be interpreted in light of relationships that may exist between the socioeconomic variables selected to the analysis. Theoretically these determinants have different meaning, but there are correlations between them, except for relationships between income poverty and other socioeconomic determinants, various forms of social capital, as well as social isolation and informal social capital . Lack of correlation between income poverty and other poverty forms and strong correlation between living conditions poverty and poverty following a lack of budget balance is well known and repeatedly discussed and influencing health care accessibility, use of cancer screening programmes and effective treatments. National policy actions which can have an important effect on the magnitude of social inequalities in cancer incidence might significantly reduce the burden and disparities in various populations and geographic areas. Our study showed that the relevance and magnitude of associations between socioeconomic variables and cancer risk vary greatly by cancer site. It provides important additional information about how socioeconomic mechanisms work. Social and economic inequalities can be avoided; therefore their limitation constitutes an achievable goal and an ethical imperative."} +{"text": "Overall growth and development of a plant is regulated by complex interactions among various hormones, which is critical at different developmental stages. Some of the key aspects of plant growth include seed development, germination and plant survival under unfavorable conditions. Two of the key phytohormones regulating the associated physiological processes are gibberellins (GA) and abscisic acid (ABA). GAs participate in numerous developmental processes, including, seed development and seed germination, seedling growth, root proliferation, determination of leaf size and shape, flower induction and development, pollination and fruit expansion. Despite the association with abiotic stresses, ABA is essential for normal plant growth and development. It plays a critical role in different abiotic stresses by regulating various downstream ABA-dependent stress responses. Plants maintain a balance between GA and ABA levels constantly throughout the developmental processes at different tissues and organs, including under unfavorable environmental or physiological conditions. Here, we will review the literature on how GA and ABA control different stages of plant development, with focus on seed germination and selected abiotic stresses. The possible crosstalk of ABA and GA in specific events of the above processes will also be discussed, with emphasis on downstream stress signaling components, kinases and transcription factors (TFs). The importance of several key ABA and GA signaling intermediates will be illustrated. The knowledge gained from such studies will also help to establish a solid foundation to develop future crop improvement strategies. Overall growth and different developmental stages of plants are under strict regulation by several classes of plant hormones. Hormone molecules are present at low concentrations in plants, and they function either at the sites of synthesis or after they are transported to different tissues of crop plants enzyme and abscisic aldehyde oxidase (AAO), respectively and AAO3 (AAO3/ABA3/LOS5) were upregulated in Arabidopsis. Furthermore, transcript levels of NCED3, ABA3/LOS5, and AAO3 were induced by abiotic stresses catalyze the deactivation reaction resulting in phaseic acid (PA) and dihydro phaseic acid (DPA) as the main ABA catabolites and in turn regulate transcription of several downstream ABA-responsive genes infection in rice by Teijiro Yabuta and co-workers was the result of an investigation of fungal from the precursor compound geranylgeranyl diphosphate (GGDP), which is aided by terpene synthases (TPSs), cytochrome P450 monooxygenases (P450s), and 2-oxoglutarate\u2013dependent dioxygenases (2ODDs) and ent-kaurene synthase (KS), which are located in the plastids are responsible for the first few steps of GA biosynthesis (conversion of GGDP to ent-kaurene). Then two P450 enzymes, namely, ent-kaurene oxidase (KO) and ent-kaurenoic acid oxidase (KAO) convert ent-kaurene to GA12. Finally, three active GAs are formed by reactions catalyzed by GA 20-oxidase (GA20ox) and GA 3-oxidase (GA3ox), that belong to 2ODDs showed drought tolerance phenotype and overexpression of GA20ox confers drought sensitivity in Arabidopsis genes and growth arrest by activating a basic leucine zipper transcription factor, ABSCISIC ACID INSENSITIVE 5 (ABI5) and activates a GA catabolic gene (GA2ox2) indirectly and represses an ABA catabolic gene (CYP707A2) which acts downstream to PIL5, leads to repression of GA biosynthesis and activation of ABI3 and ABI5 which leads to increased dormancy and hence increases the ABA level whereas it decreases the GA level by repressing GA biosynthesis genes in Arabidopsis seeds lead to changes in the plant response and therefore alter the balance of endogenous levels of GA and ABA. High temperature induces ABA biosynthesis genes module , which results in stabilization of the receptor. Conversely, opposite effect has been shown by GA by inhibiting rice SnRK2 has a link between GA and ABA signaling in rice via SnRK2-APC/CCYP707A1 and CYP707A2) -domain containing transcription factors (ATFs), Arabidopsis ABA-INSENSITIVE 4 (ABI4) and rice OsAP2-39, have key roles in the antagonistic crosstalk between ABA and GA. ABI4 positively regulates primary seed dormancy by downregulating GA biosynthesis and by inhibiting ABA catabolic genes and indirectly repressing GA biosynthesis genes (GA3ox1 and GA20ox1) , B3 domain factors LEC2, and FUSCA3 (FUS3) and modulating expression of GA metabolic genes as well as signaling cascades that regulate downstream target genes (of different classes) further add to the complexity of the already elaborate cellular communication network. This has been highlighted here with the examples of ABA and GA metabolism and their regulation. Selected genes that play significant roles in the regulation of seed dormancy and germination and various abiotic stresses were also discussed. It is evident that several positive and negative regulators of ABA and GA have direct or indirect impacts on germination and abiotic stresses. Many transcription factors and signaling components of these two phytohormones help to maintain an intricate balance between endogenous levels of bioactive ABA and GA. Furthermore, studies have identified several ABA and GA crosstalk points showing positive and negative regulation of different molecular modules associated with their metabolism and signaling. There are a few open questions that can help in formulating the future research directions. Despite the fact that there are some studies on ABA transport in different cell types and tissues, there might be many unknown pathways/transporters that are yet to be explored. Moreover, very few reports on the transport mechanism of GA are available. The antagonistic roles of GA and ABA in controlling developmental processes have been established by several pieces of evidence; however, there could be synergistic crosstalk between GA and ABA in some instances whose underlying molecular mechanisms remain undiscovered. Although several target genes of a few TFs have been established (Yaish et al., BV and PK conceived the idea and wrote the manuscript.The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest."} +{"text": "Escherichia coli (aEPEC) has been increasing worldwide.

We conducted focus groups with 25 clinicians and administrative leaders from academic and community primary care practices to 1) understand how CI is being assessed, and 2) evaluate the feasibility of implementing the MyCog paradigm into existing primary care workflows. Several key themes emerged from the discussions. No proactive detection strategy for CI was regularly used outside of the Medicare Annual Wellness Visits (AWV); variable assessments including the Minicog, MoCA, or MMSE were used to fulfill the AWV requirement. Regarding the feasibility of our MyCog Paradigm, our 2-step process was positively received, with the brief case-finding step 1 satisfying AWV requirements and replacing the longer assessments currently being used. Clinicians preferred that step 2 be self-administered due to limited clinician time for wellness visits, and highlighted logistical challenges such as room availability and storage and maintenance of the iPad.

Focal amplifications with \u226515 or \u22655 additional copies of at least one of these regions were associated with a poor overall survival among patients with stage I-III MSS CRCs . All high-level amplifications were focal and had a more consistent relationship with gene expression than lower amplitude and/or broad-range amplifications, suggesting specific targeting during carcinogenesis. Genome-wide, copy number driven gene expression was enriched for pathways characteristic of the CMS2-epithelial/canonical subtype, including DNA repair and cell cycle progression. Furthermore, 50% of upregulated genes in CMS2-epithelial/canonical MSS CRCs were driven by CNAs, an enrichment compared with the other CMS groups, and associated with the stronger correspondence between CNAs and gene expression in malignant epithelial cells than in the cells of the tumor microenvironment . In conclusion, we identify novel recurrent amplifications with impact on gene expression in CRC and provide the first evidence that CMS2 may have a stronger copy-number related genetic basis than subtypes more heavily influenced by gene expression signals from the tumor microenvironment.About 80% of colorectal cancers (CRCs) have chromosomal instability, which is an integral part of aggressive malignancy development, but the importance of specific copy number aberrations (CNAs) in modulating gene expression, particularly within the framework of clinically relevant molecular subtypes, remains mostly elusive. We performed DNA copy number profiling of 257 stage I-IV primary CRCs and integrative gene expression analysis in 151 microsatellite stable (MSS) tumors, focusing on high-level amplifications and the effect of CNAs on the characteristics of the gene expression-based consensus molecular subtypes (CMS). The results were validated in 323 MSS tumors from TCGA. Novel recurrent high-level amplifications with a major impact on gene expression were found for BRAF mutation in CMS1 and KRAS mutation in CMS3, and the low frequency of somatic copy number aberrations (CNAs) in MSI is well established. However, little is in general known about the genetic basis for the distinct gene expression-based subtypes.Colorectal cancers (CRC) can be classified into four biologically distinct and clinically relevant consensus molecular subtypes (CMS) based on their global gene expression patterns .

To control for the potential impact of different numbers of samples in the subtypes, we performed random sampling (n\u2009=\u20091000) of 20 tumors from each CMS group and repeated analyses for each iteration. Enrichment was assessed in pairwise comparisons among the subtypes. For a gene to be assessed in the in cis analysis, at least three tumors had to be found in the copy number gain and copy number neutral group. For robustness, the analysis was done in three different ways: (i) by identifying significant in cis genes for the 40 tumors (20 tumors in each of the subtypes included in the pairwise comparison) and performing differential expression analysis for the 20 versus 20 tumors per re-sampling, (ii) by identifying significant gain/upregulated genes for the 40 tumors per re-sampling and using the differential expression results from the original analyses including all samples, and (iii) by identifying significant in cis genes for the 40 tumors and randomly sampling 250 genes from the original differential expression results. Furthermore, to test if the variable number of genes that were differentially upregulated in each subtype affected the analysis we also performed repeated (n\u2009=\u20091000) re-samplings of 250 genes from the original gain/upregulated gene list and among the genes originally found to be upregulated in each CMS group (CMSx versus remaining CMS classified tumors).To investigate a potential enrichment of genes with in cis-association (gain/upregulation) among upregulated genes in each of the four CMSs we identified differentially expressed genes between each subtype and the remaining subtypes using limma were used for integration analyses with CNAs.

Twelve years after cardiologists and cardiac surgeons from all over the world issued the Drakensberg Declaration on the Control of Rheumatic Fever and Rheumatic Heart Disease in Africa, calling on the world community to address the prevention and treatment of rheumatic heart disease (RHD) through improving living conditions, to develop pilot programmes at selected sites for control of rheumatic fever and rheumatic heart disease, and to periodically review progress made and challenges that remain,2Prevention efforts have been important but have failed to eradicate the disease. At the present time, the only effective treatment for symptomatic RHD is open-heart surgery, yet that life-saving cardiac surgery is woefully absent in many endemic regions. In this declaration, we propose a framework structure to create a co-ordinated and transparent international alliance to address this inequality.Elimination of RHD and relief from its debilitating consequences can only occur through interdisciplinary effort, as outlined in the Cairo Accord.Progress in the prevention of RHD has been slow during the past 15 years,6Although there is one cardiac centre per 120 000 people in the United States, there is only one centre per 33 million in Africa. Furthermore, RHD is not restricted to sub-Saharan Africa. India, Pakistan, China and Indonesia together account for 72% of the mortality rate of RHD cases worldwide.2We strongly endorse the position that building local capacity is the best solution for this serious public health problem. Many lives have been saved by humanitarian \u2018fly-in\u2019 missions, but these efforts are neither sustainable nor cost effective. The non-governmental organisations associated with these programmes are shifting focus towards building long-term partnerships with host countries to develop autonomous local services with government buy-in.It is not sufficient for governments and non-governmental organisations to support the training of cardiologists and cardiac surgeons from these regions at high-income country facilities, because they will not be trained in most of the pathologies awaiting them in their own countries and will be unfamiliar with resource-constrained circumstances.There is an urgent need for a concerted effort by all stakeholders to address the plight of the poor in these regions, who need cardiac surgery. As signatories and endorsing organisations of the Cape Town Declaration, we propose a comprehensive solution with two principal aims.Aim 1: To establish an international working group of individuals from cardiac surgery societies and representatives from industry, cardiology and government to evaluate and endorse the development of cardiac care in low- to middle-income countries.It is proposed that the international coalition will have two representatives from each of the major cardiac surgery societies , and ideally, two additional committed members. There will be at least one representative from industry and at least one appointee to represent cardiology/the World Heart Federation. The responsibilities of the coalition will include establishing criteria for centres for clinical care and training as well as selecting and endorsing the centres. The coalition will derive metrics of quality and performance for the endorsed centres of training and clinical care and will encourage standardisation of care to the extent possible.The coalition will advocate mutually agreed policies and prescriptions to relevant governmental bodies. In addition, the coalition will engage with industry and private sources of philanthropy for financial assistance with large-scale initiatives.Aim 2: To advocate for the training of cardiac surgeons and other key specialised caregivers at identified and endorsed centres in lowto middle-income countries.The case has been made above for critical providers obtaining training in settings and conditions and dealing with the cardiac pathologies that they will be encountering in their practice in their countries of origin.It is preferred that centres endorsed by this coalition be based on an alliance of four stakeholders: a programme initiator , an audited training centre in a low- to middle-income country, a committed partner institution in a high-income country, and a consortium of industry that would sign on as benefactors to the specific programme. Because regional centres in low- to middleincome countries typically operate within a resource-scarce environment, resulting in lower case numbers than needed for the training of outside residents, a facilitated capacity increase to help achieve higher case numbers would benefit all participants.Summary: It is imperative that action be taken urgently. A nucleus of one to three centres should be identified and endorsed, with co-ordination by global stakeholders, as quickly as possible. The implementation of this initiative will only be made possible by the endorsement of all the relevant cardiothoracic societies and agencies subscribing to clearly defined targets and timelines, and committing appropriate resources.

GSD has a high prevalence in populations with European or Amerindian ancestry (10\u201320%) and the influence of genetic factors is broadly acknowledged. However, known genetic variants do not entirely explain the disease heritability suggesting that additional genetic variants remain to be identified.

Investigators from Calico Life Sciences LLC and AbbVie report the effects of a novel drug targeting the genetic basis of Vanishing White Matter Disease (VWMD). VWMD is caused by homozygous or compound heterozygous variants in any of five genes . Collectively the five genes encode a portion of the eukaryotic translation inhibition factor 2 (eIF2) termed eIF2B that is required for normal protein translation. VWMD-causing variants are though to cause a partial reduction in eIF2B activity. Prior studies by members of the group from Calico Life Sciences had shown that ISR-inhibitor (ISRIB), a small molecule, was able to activate and stabilize eIF2B [COMMENTARY. VWMD is a chronic, episodic and progressive leukoencephalopathy with highly variable presentation. Features include essentially normal early life development followed by progressive ataxia, cognitive impairment, and spasticity. In 1997 Van Der Knapp et al., proposed four criteria for diagnosis (1) essentially normal initial motor and cognitive development, (2) chronic, progressive deterioration that often follows a mild infection or head trauma, 3) progressive cerebellar ataxia and spasticity are prominent features; epilepsy and optic atrophy may be present; cognitive impairments are less significant than motor impairments and (4) MRI findings are symmetric, with white matter signal intensity similar to cerebrospinal fluid on multiple sequences [ progressWhen clinical suspicion is high, the diagnosis of VWMD is confirmed by genetic testing for homozygous or compound heterozygous variants in genes encoding the five eIF2B subunits. Normal protein expression requires function of eIF2B to extend translated RNA sequences . While tThe other important function of eIF2B is regulation of the integrated stress response (ISR), a reprogramming of protein expression that is common for a variety of cellular stress signals. ISR both shuts down normal protein expression, and activates specific transcription factors to help protect a stressed cell. Prior work demonstrated that suppression of eIF2B activates the ISR. ISRIB efficiently activates and stabilizes eIF2B to block the ISR .VWMD is caused by diminished eIF2B activity and often worsens in the setting of illness, which may be related to improper regulation of the ISR. The current investigation examined whether ISRIB can utilize the hypoactive eIF2B found in VWMD to properly inhibit the ISR. The authors selectively edited the eIF2B gene with CRISPR-Cas9 in otherwise normal cells to recreate patient derived mutations. Cells were then treated with ISRIB. Consistent with a properly inhibited ISR, global protein expression was increased and ISR-specific transcription factors were decreased [The author(s) have declared that no competing interests exist."} +{"text": "A 78-year-old patient with a recent history of transitory ischemic attack with right upper extremity weakness was referred for computed tomographic angiography (CTA) of the neck arteries.

The landscape comprises continuous forest on steep slopes and small riparian forest fragments in a grassland matrix. While increased fragmentation is well documented for these and other forests in the mountains of Cameroon and Nigeria over the past century, there are no previous assessments of the impact of forest fragmentation on montane amphibian populations in this region. Our estimates of genetic diversity are similar across populations within each species with levels of heterozygosity values consistent with local population declines. Except for a pair of populations (C. schioetzi) we did not observe genetic differentiation between forest and riparian forest fragment populations, nor across sites within continuous forest (L. bicolor). Our results demonstrate recent gene flow between forest fragments and the adjacent protected forests and suggest that small forest corridors connecting these may lessen the genetic consequences of at least 30 years of intense and severe fragmentation in Ngel Nyaki.Amphibians are the vertebrate group with the highest number of species threatened with extinction, and habitat loss and fragmentation are considered to be among the leading causes of their declines and extinctions. Little is known of the population biology of amphibian species inhabiting montane forests in Central and West Africa, where anthropogenic activities such as farming and cattle raising are major threats to native biodiversity. We used Amplified Fragment Length Polymorphisms (AFLPs) to assess the population genetic structure of two poorly known species, Globally, amphibians face the most extreme population declines of all major vertebrate groups \u20133.

In cancers arising from KRT17 negative single layered epithelia neo-expression of KRT17 has been associated with tumor progression. To obtain more insight into the biology of kidney cancers we have investigated KRT17 expression by immunohistochemistry in normal kidney, in papillary preneoplastic lesions and in 151 papillary and 692 conventional renal cell carcinomas placed on tissue microarray. We found a positive staining in ureteric bud and collecting duct cells in foetal kidney, in all papillary preneoplastic lesions and also in 77% of the 151 papillary renal cell tumors indicating a continuos KRT17 expression during tumor development. The neo-expression of KRT17 in conventional renal cell carcinomas, which derives from KRT17 negative proximal tubules showed a significant correlation with postoperative tumor relapse . In conclusion, the continuous expression of KRT17 from emerging fetal kidney tubules and microscopic pre-neoplastic lesions towards papillary renal cell tumors and its neo-expression in aggressive growing conventional renal cell carcinomas reflects the multiple function of KRT17 in kidney cancers with distinct natural history. This should be taken into account in clinical managements and therapy.Expression of KRT8 and KRT18 in their normal state, but this may change during inflammation, regeneration and also during tumor development. Kidney tubular cells may switch on KRT7 and KRT19, sometimes also KRT17 in addition to the expression of KRT8 and KRT18KRT7, KRT17 and KRT19 appears parallel to the reduction in degree of differentiation. KRT7 and KRT19 are upregulated during renal epithelial injury and repair leading to more plasticity of cells involved in the regeneration processes KRT8 and KRT18 expression to KRT7 and KRT19 is associated with structural remodelling of end stage kidney and increased frequency of tumors expressing both KRT7 and KRT19KRT17 in the biology of kidney cancer is not yet known. Two earlier studies on the keratin expression in distinct types of renal cell cancer using the E3 clone from DAKO did not find KRT17 expression in conventional, chromophobe and papillary renal cell tumors or renal oncocytoma Keratins are intermediate filaments playing a crucial role in the integrity and mechanical stability of single epithelial cells and epithelial tissues. The expression of keratins is regulated in a tissue-type and differentiation-specific manner KRT17 a member of type I acidic epithelial keratin family was first identified in skin basal cell epithelioma and it is considered to be a basal/myoepithelial cell keratin KRT17 occurs in complex, multilayered epithelia and it is largely retained during neoplastic transformation leading to several types of cancer derived from such epithelial cells KRT17 expression has also been detected in several tumors of non-epithelial type but not in their tissue of origin. These studies demonstrated a correlation between neo-expression of the KRT17 and tumor progression KRT17 in fetal development, regeneration and tumorigenesis and on the other hand in the progression of frankly malignant cancers.KRT17 in the biology of renal tumors we applied immunohistochemistry to a large panel of conventional RCC and papillary RCT as well as to preneoplastic lesions (PNL) associated with papillary RCT. In our study we used an antibody arised against the N-terminal protein fragment of KRT17 instead of the E3 clone from DAKO .In attempt to learn about the involvement of We have enrolled tumor samples from consecutively operated patients without selection, who undervent radical or partial nephrectomy due to kidney cancer between 2000 and 2013 at the Department of Urology, Medical School, University of Pecs, Hungary. The only criteria was the availability of clinical data, follow-up and paraffin embedded tumor material. Data on regular follow-up and tumor-specific death were obtained from the Registry of the Department of Urology. Follow-up was defined as time from operation until the last recorded control in 2018, or cancer-specific death. Patients who died from causes other than RCC were excluded from this analysis. Preoperative clinical staging included abdominal and chest computed tomography (CT) scans. Bone scans and brain CT scans were obtained only when clinically indicated. The presence of nodal metastases was confirmed by histological, whereas that of distant metastases by radiographic examination. During the postoperative period patients were surveyed every 6 months by abdominal ultrasound scans, serum creatinine and eGFR measurements, and every year by CT scans. Histological diagnoses were performed by a genitourinary pathologist (GK) according to the Heidelberg and TNM classification systems Haematoxylin and eosin stained slides were reviewed to select the representative paraffin blocks and tumor areas for TMA construction. From each tumor minimum three core biopsies with a diameter of 0.6 mm were placed in the recipient block using a Manual Tissue Arrayer . For marking the TMAs fetal and adult kidney biopsies were included.0C in a moist chamber with rabbit polyclonal anti-KRT17 antibody at 1:500 dilution. Horse-radish-peroxydase conjugated anti-rabbit, anti-mouse secondary antibody was applied for 30 minutes at room temperature and the bound antibody was visualized with AEC (Amino-ethyl-carbazol) . Tissue sections were counterstained with Mayer's haematoxylin. In negative control the primary antibody was omitted. The slides were evaluated twice at different times by two of the authors . The staining intensities were scored as low, medium or high. As we did not find substantial differences between weak or strong KRT17 expression and conventional RCC progression, we have evaluated all staining intensity as positive.Paraffin blocks of fetal and adult kidneys, pre-neoplastic lesions and TMAs were used for immunohistochemistry. After deparaffinisation and rehydration the 4 um thick sections were subjected to heat-induced epitope retrieval in citrate buffer, pH 6.0 in 2100-Retriever . Endogenous peroxidase activity and unspecific binding sites were blocked with 3% hydrogen peroxide containing 1% normal horse serum for 15 minutes at room temperature. Slides were incubated overnight at 4KRT17 expression, clinical and pathological parameters were calculated using the \u03c72 test. The effects of the different variables on the survival of the patients were estimated by Kaplan-Meier analyses. Comparisons of survival curves were made using the Log rank test. Univariate and multivariate survival analyses were performed using the Cox regression model. Patients that were alive and disease-free were censored. Differences were considered significant at p < 0.05.Data analyses were performed using a SPSS Statistics software package version 25 . Correlations between KRT17 first appeared in the ureteric bud and collecting duct of fetal kidney , the average follow-up was 60.6\u00b133.2 months. Out of the 692 patients 108 (16%) developed metastasis during the follow-up and died due to metastatic cancer. The clinical parameters and correlation with KRT17 expression is shown in Table KRT17 staining which showed a significant correlation with cancer specific death, tumor size, T-stadium, grade and stage. The Kaplan-Meier analysis indicated that patients with KRT17 positive tumor have a significantly shorter survival than those with negative tumor . The KRT17 expression was an independent negative survival factor indicating a nearly three times higher risk of disease relapse and cancer specific death .To estimate the role of KRT17 has other functions as well. KRT17 plays a role in fetal epidermal development and in cell proliferation during wound healing by regulation of protein synthesis through intracellular signaling pathways KRT17 knockout mouse embryos show a delay in closure of surface ectoderm wounds KRT17 binds and sequester TRADD (TNFRSF1A associated via death domain), a mediator of programmed cell death signaling and protects the cells from apoptosis KRT17 null keratinocytes are sensitive to TNF mediated apoptosis KRT17 expression in embryonic ectoderm reflects its commitment towards distinct epithelial lineages and that the program of gene expression characteristic of wound-activated adult keratinocyte may have a relationship to that executed by epithelial cells at specific stages of embryonic development CD44+/KRT17+ cells have stemlike properties, including the capacity for cell renewal and in vivo tumorigenicity Beyond its role to maintain cellular integrity of multi-layered epithelia KRT17 is expressed in simple (one-layered) epithelial cells of fetal and adult kidney. Each PNL of embryonal origin as well as 77% of papillary RCT showed the KRT17 positivity irrespectively of cell type. Taking into account that only 5% of papillary RCTs developed metastasis during 5-year follow-up (data not shown), the role of KRT17 in the progression of papillary RCT can be excluded. Rather, the expression of KRT17 in fetal kidney suggests that it may play a role in the cell specific differentiation of tubular cells similarly to its role in fetal epidermal development KRT17 is associated with the development of PNL and subsequently of papillary RCT. This finding indicates a molecular relationship between kidney development and papillary RCT tumorigenesis. The developmental sequences outlined by KRT17 expression support our hypothesis on the unique natural history of papillary RCT We showed in this study that KRT17 is a basal/myoepithelial cell keratin the expression of which depends on the position of cells in complex multiplayer human epithelia KRT17 has been described in bladder carcinoma, keratoacanthoma and squamous cell carcinoma, oral squamous cell carcinoma, premalignant and malignant squamous lesions of the cervix, all derived from multilayer epithelial cells KRT17 has also been found in several other types of cancer such as gastric adenocarcinoma, ovarian and breast carcinoma, papillary thyroid carcinoma but not in their corresponding normal tissue KRT17 in these cases showed a significant correlation with tumor progression and metastasis. We have identified KRT17 expression in conventional RCCs as an independent negative survival factor indicating a higher risk for postoperative tumour relapse and cancer specific death of patients. Conventional RCC derives from KRT17 negative proximal tubules of the kidney, which suggests that KRT17 has not been involved in the development of conventional RCC. Rather, the neo-expression of KRT17 in conventional RCC can be used as a predictive biomarker similar to gastric, ovarian or breast carcinoma KRT17 in gastric cancer cells inhibited cell proliferation both in vitro and in vivo conditions, reduced the migration of tumor cells and induced apoptosis by BCL2 expression. They also showed that silencing KRT17 leads to cell-cycle arrest at G1/S phase of tumor cells. The clinical, pathological as well as experimental data strongly suggest the involvement of KRT17 neo-expression in tumor progression.Expression of KRT17 is expressed in a single-layered epithelia, and that papillary RCT and conventional RCC have distinct natural history. The continuous expression of KRT17 from fetal kidney tubules towards papillary RCT in adult confirm the relationship between fetal kidney development and tumorigenesis of papillary RCT. And finally, the neo-expression of KRT17 in aggressive growing conventional RCC is significantly associated with postoperative tumor relapse. The multiple functions of KRT17 in kidney cancers unequivocally delineates papillary RCTs and conventional RCCs with distinct natural history, which should be taken into account in clinical managements and therapy.The key novel findings of this study are, that"} +{"text": "Ligand binding to death receptors activates apoptosis in cancer cells. Stimulation of death receptors results in the formation of intracellular multiprotein platforms that either activate the apoptotic initiator Caspase-8 to trigger cell death, or signal through kinases to initiate inflammatory and cell survival signalling. Two of these platforms, the Death-Inducing Signalling Complex (DISC) and the RIPoptosome, also initiate necroptosis by building filamentous scaffolds that lead to the activation of mixed lineage kinase domain-like pseudokinase. To explain cell decision making downstream of death receptor activation, we developed a semi-stochastic model of DISC/RIPoptosome formation. The model is a hybrid of a direct Gillespie stochastic simulation algorithm for slow assembly of the RIPoptosome and a deterministic model of downstream caspase activation. The model explains how alterations in the level of death receptor-ligand complexes, their clustering properties and intrinsic molecular fluctuations in RIPoptosome assembly drive heterogeneous dynamics of Caspase-8 activation. The model highlights how kinetic proofreading leads to heterogeneous cell responses and results in fractional cell killing at low levels of receptor stimulation. It reveals that the noise in Caspase-8 activation\u2014exclusively caused by the stochastic molecular assembly of the DISC/RIPoptosome platform\u2014has a key function in extrinsic apoptotic stimuli recognition. Death receptors are targets of novel cancer therapeutics. Most of them signal through flexible multiprotein platforms to either activate apoptotic or necroptotic cell death, or propagate cell survival and pro-inflammatory signals. We focused our study on the role of dynamic assembly and composition of these platforms in the initiation of cell death at the single cell level. Since the assembly is slow through the competitive nature of protein binding within the platforms core we developed a stochastic mathematical model of the death inducing signalling platform. Our model provided an explanation for delayed cell death and fractional killing upon the death receptor stimulation. Additionally, we found that the variability in the cell death response arises through the random assembly initiates a slow noise-prone ramp activation of initiator Caspase-8 spontaneously triggering the apoptotic cascade. Our computational simulations predicted high variation in the time required for cell death induction at the single cell level and highlighted a significant role of death receptor clustering in effective Caspase-8 activation. Our knowledge and data driven model captures detailed processes governing the early events of cell death initiation and can be used to guide the development of more rational combinational treatments against cancer. Apoptotic signalling cascades are designed to irreversibly lead to cell death once specific death thresholds are overcome ,2. Activin vivo studies have shown that fractional death resistance has no direct association with the amount of DRs expressed on the plasma membrane is the total number of receptors per cell and Caspase 6 (Casp6) which is triggered by stochastically activated Casp8.

Ubiquitination of active Casp3, which is set by XIAP, will attract proteasomal complex leading to Casp3 degradation.

Alloxan acts in two ways: it selectively inhibits glucose-induced insulin secretion through specific inhibition of glucokinase, the glucose sensor of the beta cell, and it causes a state of insulin-dependent diabetes through its ability to induce reactive oxygen species (ROS) formation, resulting in the selective necrosis of pancreatic beta cells , 3. TherIn the article by Omabe et al., type 2 diabetes has been induced by a single intraperitoneal injection of alloxan, which is not correct due to its mechanism of action."}
