This study was designed to detect the sequence variation of the chicken heat shock protein 70 (HSP70) gene. A total of 102 individuals from 8 native Chinese breeds together with Dwarf White Chicken and Red Junglefowl were used to detect sequence variations. The coding regions of the chicken HSP70 gene from 102 individuals were cloned and sequenced. Thirty-six variations were identified, which i...

BACKGROUND Since the 1980s, Rhode Island has achieved one of the highest mammography screening rates in the nation. The objective of this study was to determine the effect of high mammography rates on breast cancer presentation and outcomes. METHODS Using the Rhode Island Cancer Registry, the incidence of DCIS and invasive cancer, tumor size, stage, rate of BCS and mortality from breast cance...

The United States has one of the highest rates of teen pregnancy among industrialized countries, with more than 750,000 pregnancies each year among women less than 20 years of age. Though teen pregnancy rates in the US had declined each year since 1991, the most recent national data show that rates of teen pregnancy, abortion, and birth are on the rise. Rhode Island has 2,430 teen pregnancies p...

The noncoding control region of the mitochondrial DNA of various gallinaceous birds was studied with regard to its restriction fragment length polymorphism (RFLP) and sequences of the first 400 bases. Tandem duplication of the 60-base unit was established as a trait unique to the genus Gallus, which is shared neither by pheasants nor by quails. Unlike its close ally Gallus varius (green junglef...

Eggshell damages lead to economic losses in the egg production industry and are a threat to human health. We examined 49-wk-old Rhode Island White hens (Gallus gallus) that laid eggs having shells with significantly different strengths and thicknesses. We used HiSeq 2000 (Illumina) sequencing to characterize the chicken transcriptome and whole genome to identify the key genes and genetic mutati...
