Association of FcγRIIIB gene polymorphisms with susceptibility to chronic periodontitis in Chinese patients
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.
We discuss the integration of G.657-compatible reduced-clad bend-insensitive (RCBI) fibers into two-dimensional fiber array units (FAUs) and into FAUs incorporating 90-degree bends to enable high-density and small form-factor fiber-chip connectivity solutions.
