conclusions lepr q223r polymorphisms may confer a significant risk of nafld and coronary atherosclerosis. the a allele in the k109r polymorphism might be considered an independent risk factor for coronary atherosclerosis in nafld patients. objectives to investigate the association of lepr polymorphisms at q223r and k109r with the risks of nafld and coronary atherosclerosis in the chinese han po...
background chronic hepatitis b virus (hbv) infection is a multifactorial disease that can result in serious clinical complications. host genetic background especially the genes that encode immunologic factors like inf-γ and its receptor (ifn-γ r) are critical in the pathogenesis of infection. materials and methods genomic dna from peripheral blood samples of 200 chronically hbv infected patient...
Purpose: Estrogen as a crucial hormone during pregnancy acts by two types of receptors. Estrogen receptor alpha, expressed by estrogen receptor 1 (ESR1) gene, is more abundant and exists in all human reproductive systems. Association of ESR1 gene polymorphism has been shown in some reproductive fields such as spontaneous abortion, endometriosis-related infertility and in vitro fertili...
Background and purpose: Cytokines are a group of endogenous proteins which play an influential role in regulating the inflammatory responses and defeating infectious diseases. Elevated levels of proinflammatory cytokines and their receptors are usually observed in association with immune responses against viral infections such as hepatitis B virus (HBV) infection. IL 12 and its receptor play an...
Background and Aims: Ficolins are proteins that bind to carbohydrates, act as opsonins and play an important role in innate immunity. Polymorphism in ficolin-3 gene (FCN3) can lead to complement deficiency and increase the risk of some disorders such as diabetes. The aim of this study was to investigate the frequency of FCN3+1637delC as a single nucleotide polymorphism in this gene in healthy a...
Background: Tuberculosis (TB) is one of the most significant health-care problems worldwide. The host’s genetics play an important role in the development of TB in humans. The disease progresses through several stages, each of which can be under the control of different genes. The precise genes influencing the different stages of the disease are not yet identified. The aim of the current study ...
background: obesity is a very common disorder resulting from an imbalance between food intake and energy expenditure, and it has a substantial impact on the development of chronic diseases. the aim of this study was to examine the association of insig2 (rs7566605) gene polymorphism with obesity and obesity associated phenotypes in north indian subjects. methods: the variants were investigated ...
مقدمه بیماری های چند عاملی یکی از مهمترین مباحث علوم زیستی می باشند که بدلیل تداخل عوامل محیطی و ژنتیکی به سختی از هم قابل تفکیک می باشند. سندرم متابولیک یکی از این بیماری ها است که ساز و کارهای دخیل در آن پیچیده هستند و عوامل ژنتیکی و محیطی جزء عوامل مهم در بیماریزایی این سندرم می باشند، بنابراین تعیین مدل برای بررسی این نوع بیماری ها ممکن نیست. یکی از راهکار ها جهت حل این معضل؛ استفاده از رو...
Introduction: Hepatitis B virus (HBV) infection is a major health problem worldwide and may lead to serious clinical complications, including chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. The host’s genetic background in immune system genes is a crucial etiologic factor in progression of HBV infection to chronic disease or clearance of the virus from the body. Interleu...
