the biobreeding- diabetes prone (bb-dp) rat spontaneously develops an autoimmune diabetic syndrome that is dependent on the rt1 u major histocompatibility complex (mhc) haplotype and homozygosity for an allele at the lymphopenia (lyp) locus. lyp mutation is responsible for a peripheral t -lymphopenia. there are other genetic loci contributing to diabetes susceptibility in this strain. bb rats c...

In this study, the Wild-type and recently-isolated five color-mutations of Japanese quail were compared for their meat yield potentialities. Results showed that the color-mutations; BB-White, BB-Tuxedo, BBBlack, BB-Dhakaya and the Wild-type quail were more fertile (p < 0.01) than the BB-Rosetta mutation. Chick mortality was higher (p < 0.01) in the BB-Tuxedo than in the Wild-type and other muta...

We prove that adding to the pure-calculus a non-deterministic choice operator and a standard numeralsystem we obtain a language which internally discriminates two-terms if and only if they have diierent BB ohm trees.

objectives: this study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. materials and methods: class v cavities (4x2x2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. in the control group, single bond (sb) adhesive was applied after etching. in bb+sb...

BACKGROUND It has been suggested that the vitamin D receptor (VDR) gene BsmI-polymorphism is a genetic determinant of bone metabolism. DESIGN To test this hypothesis, the relationship between VDR genotypes, bone mineral density (baseline and after 18 months) and parameters of calcium metabolism and bone turnover were investigated prospectively in 88 haemodialysed patients not receiving active...
