Increased chemosensitivity has been observed in HF (heart failure) and, in order to clarify its pathophysiological and clinical relevance, the aim of the present study was to investigate its impact on neurohormonal balance, breathing pattern, response to exercise and arrhythmic profile. A total of 60 patients with chronic HF [age, 66+/-1 years; LVEF (left ventricular ejection fraction), 31+/-1%...
Deciphering the evolutionary processes driving nucleotide variation in multiallelic genes is limited by the number of genetic systems in which such genes occur. The complementary sex determiner (csd) gene in the honey bee Apis mellifera is an informative example for studying allelic diversity and the underlying evolutionary forces in a well-described model of balancing selection. Acting as the ...
The analysis of mitochondrial DNA (mtDNA) hypervariable region (HVR) sequence data from ancient human remains provides valuable insights into the genetic structure and population dynamics populations. mtDNA is particularly useful in studying populations, because it maternally inherited has a higher mutation rate compared to nuclear DNA. To determine three Colombian pre-Hispanic populations comp...
This study reports on variations at the mitochondrial DNA (mtDNA) hypervariable region 1 (HVR-1) and at seven Y-chromosome microsatellites in an African-American population sample from Chicago, IL, USA. Our results support the hypothesis that the population studied had undergone a European male-biased gene flow. We show that comparisons of intra-and inter-population diversity parameters between...
پروتئین BoLA-DQA، ناحیهای با چندشکلی بسیار بالا در کلاس MHC-II است که نقش مهمی در پاسخهای ایمنی، حساسیت و مقاومت به بیماریها، واکسیناسیون و فاکتورهای تولیدی ایفا میکند. در این مقاله جنبههای تغییرپذیری ساختاری و فیلوژنتیک لوکوسBoLA-DQA شناسایی شد. توالی پروتئینی آللهای BoLA-DQA از پایگاه دادهها استخراج گردید. پلات تغییرپذیری برای 60 آلل با استفاده از روش آنتروپی پلات شانون از روی همردیفی ...
