Structure and replication of hepatitis delta virus RNA.
While this volume covers many different aspects of hepatitis delta virus (HDV) replication, the focus in this chapter is on studies of the structure and replication of the HDV RNA genome. An evaluation of such studies is not only an integral part of our understanding of HDV infections but it also sheds new light on some important aspects of cell biology, such as the fidelity of RNA transcription by a host RNA polymerase and on various forms of post-transcriptional RNA processing. Representations of the replication of the RNA genome are frequently simplified to a form of rolling-circle model, analogous to what have been described for plant viroids. One theme of this review is that such models, even after some revision, deceptively simplify the complexity of HDV replication and can fail to make clear major questions yet to be solved.

Synthesis and integration of avian sarcoma virus DNA.
In this paper, we have presented data regarding the integration of viral DNA and the persistence of unintegrated viral DNA. We know that integration occurs with specificity with respect to the viral genome, and yet it remains to be established which, if any, of the unintegrated DS DNA species-either the linear or the covalently closed circular forms-is the immediate precursor to the DNA that does become integrated. The results of the present studies indicate that the viral DNA species that are able to persist in an unintegrated state may be transcribed to yield new virions. Furthermore, these species may not be intermediates as far as the integration pathway, but may instead be terminal products of a synthesis reaction that has proceeded beyond the point where integration normally occurs. Varmus et al. (1977) have shown that integration occurs only into newly replicated cellular DNA. Therefore, we would speculate that integration may occur by an interaction between a replication fork of the host cell DNA and an earlier, non-double-strand form of viral DNA.

The influence of protection, palliation and costs on mobility optimization of residents in nursing homes: a thematic analysis of discourse.
BACKGROUND
With the aging of the population, increasing numbers of older people live in nursing homes. Discourse such as policies and standards highlight the need to optimize the mobility independence of residents. This is expected to occur in a way that is safe for residents and staff whilst meeting the residents' needs. The influence of discourse on health care delivery can be poorly understood, being at times hidden or taken for granted. The aim of this study was to uncover discourse relevant to resident mobility optimization to enable the origins and reasoning behind existing and intersecting policy and practice to be critically appraised.


DESIGN
Narrative literature review and thematic analysis with a focus on discourse were employed for this study.


DATA SOURCES
Databases (CINAHL and Ovid Medline) and websites of relevant professional and governmental bodies were accessed.


METHOD
A literature search centered on retrieval of texts focused on discourses that influenced goals to optimize resident mobility. Database searches for texts covered the period from 1994 to 2011. Iterative thematic analysis focussed on the texts' socio-cultural context and influence.


FINDINGS
Four discourses emerged that potentially influence goals to optimize resident mobility: safe manual handling; falls prevention; palliative care; and costs and funding constraints to individualized care. These discourses may influence mobility care in the direction of more routinized, passive and dependency support approaches. A common overarching theme was that of collaboration and communication.


CONCLUSION
Discourses such as safe manual handling, falls prevention, palliative care and cost constraints to individualized care can negatively impact on the goal to optimize the mobility of residents in nursing homes. Inter-professional approaches where staff work collaboratively and communicate well may counter such influences and ensure individualized care that focuses more effectively on resident mobility.

The smacking controversy: what advice should we be giving parents?
BACKGROUND
Even among countries that have ratified the United Nations Convention on the Rights of the Child there is much disagreement about corporal punishment of children. Last year the Scottish Executive proposed a new law banning the smacking of children under the age of three, becoming the tenth European nation to do so. The proposal, currently abandoned whilst ostensibly still under debate, has raised a wave of controversy in child protection circles. In the nearest neighbouring country, England, a similar proposal was robustly rejected. PURPOSE OF THE PAPER: Given an increasing family and community focus in nursing, the implications of the debate for the profession cannot be ignored. What should we be telling 'ordinary' families about smacking? Thus this paper presents a positional statement on the smacking controversy and outlines some pointers for practice.


DISCUSSION
While for many the legislation proposed does not go far enough, others decry it as a breach of parental rights and, thus, the issue has become hugely controversial. Media opinion and various opposing campaigns dominate both public and professional spheres. Rights, responsibilities, examples from other countries, culture and gender are all used as fodder in the debate. Extreme examples are cited by both sides and used as grist for what are at times tenuous arguments. As there is even a division within child protection arenas, practising professionals may struggle to find a way through the maze of seemingly contradictory findings from research, policy and opinion.


CONCLUSIONS
A wide range of literature suggests that both public and professional opinion is divided on the use of smacking as a form of discipline of young children. Opinion is also divided on the ability of legislation to bring about change in social attitudes and behaviour. Health care professionals need to be in a position to recommend best practice and to do so consistently.

Results of a National Survey on Over-The-Counter Medicines, Part 1: Pharmacist Opinion on Current Scheduling Status
Background: OTC medicines make up an important part of the community pharmacy world. As with most aspects of practice, however, hurdles exist that prevent an optimal level of care. Objective: To gauge pharmacist agreement on the scheduling status of various OTC medicines. Methods: Pharmacists across Canada were surveyed by mail. Results: Of the 5037 surveys mailed, 2403 were returned, with 2305 being usable for analysis (response rate of 49.4%). Across 25 agents, pharmacists tended to support existing control for pharmacies (such as Nix crème rinse and minoxidil topical solution) and returning control to pharmacies for unscheduled agents (such as ranitidine 75 mg tablets and nicotine patches). Conclusions: Pharmacists generally favour tighter control of OTC agents, especially those that are unscheduled. This hopefully reflects pharmacist desire to ensure their proper selection and use.

Protein biofortified sorghum: effect of processing into traditional african foods on their protein quality.
Protein biofortification into crops is a means to combat childhood protein-energy malnutrition (PEM) in developing countries, by increasing the bioavailability of protein in staple plant foods and ensuring sustainability of the crop. Protein biofortification of sorghum has been achieved by both chemically induced mutation and genetic engineering. For this biofortification to be effective, the improved protein quality in the grain must be retained when it is processed into staple African foods. Suppression of kafirin synthesis by genetic engineering appeared to be superior to improved protein digestibility by chemical mutagenesis, because both the lysine content and protein digestibility were substantially improved and maintained in a range of African foods. For the genetically engineered sorghums, the protein digestibility corrected amino acid score was almost twice that of their null controls and considerably higher than the high protein digestibility sorghum type. Such protein biofortified sorghum has considerable potential to alleviate PEM.

What does the Driving and Riding Avoidance Scale (DRAS) measure?
Driving anxiety can have a significant impact on everyday functioning and usually results in some kind of avoidance behaviour. The Driving and Riding Avoidance Scale (DRAS; Stewart, A. E., & St. Peter, C. C. (2004). Driving and riding avoidance following motor vehicle crashes in a non-clinical sample: psychometric properties of a new measure. Behaviour Research and Therapy, 42, 859-879) shows promise in the self-report assessment of the degree of such avoidance. The present study investigated the psychometric properties of the DRAS in a sample of 301 university students. Internal consistency for the DRAS was 0.89 and temporal stability over two months was 0.71. The factor structure of the DRAS supported the use of the general and traffic avoidance subscales but not the weather and riding avoidance subscales in the present non-clinical sample. However, a significant limitation of the DRAS is that it does not assess the reasons for driving avoidance, and is therefore not a measure of avoidance that is due to driving anxiety. Some items may be rated highly for practical reasons, such as avoidance because of increasing fuel and other costs associated with driving. Modified instructions for the DRAS should ensure that it measures anxiety-related avoidance behaviour.
