Varietal identification of rice prolamins by capillary zone electrophoresis
Capillary electrophoretic methods were developed to investigate the possibility of prolamin identification of four rice varieties i.e. Thai white fragrant rice KD105, Korkhor15, Thai white rice A, and a Chinese white rice H20. Two extraction methods were compared and varietal identification of rice prolamins was successfully accomplished by capillary electrophoresis in pH 2.5, sodium phosphate buffer containing 20% acetonitrile and 0.05% hydroxypropylmethylcellulose.
Objective To investigate the relationship between FcγRⅢB gene polymorphisms and susceptibility to chronic periodontitis in Chinese patients. Methods DNA samples with buccal swabs were collected from 63 severe CP patients, 103 initial to moderate CP patients, and 80 healthy controls in Chinese Han nationality. The FcγRⅢB gene polymorphisms were analyzed with PASA. Results There were no significant genotype distribution differences of FcγRⅢB between any two of the three subject groups. Conclusion Further study was needed since we did no find the relationship between the FcγRⅢB gene polymorphism and periodontitis in this present study.
