materials and methods in this case-control study, using the polymerase chain reaction (pcr), adrs266729 and rs2241766 gene polymorphisms were genotyped in b-type ultrasonography-proven nafld patients, with (n = 246) or without (n = 247) cad and in healthy controls (n = 304). serum lipid profiles were determined using biochemical methods. statistical analyses were performed using spss 17.0 stati...

objectives: genetic polymorphism interactions are among the important factors in affliction with complex diseases like alzheimer’s disease. the important goal of genetic association studies is to identify a combination of polymorphisms and measure their importance in increasing the risk of occurrence of such diseases. in this study, feature selection approach of logic regression was used to ide...

introduction: hepatitis b is a potentially life-threatening infection that causes acute infection and chronic hepatitis with progression to cirrhosis and hepatocellular carcinoma (hcc). interleukin-12 (il12) is responsible for activation of th1 immune responses, leading to possible clearance of hbv infection from the host’s body. the host’s immune-genetic background plays an important role in t...

allele frequencies of single nucleotide polymorphisms (snps) are variable among different populations; therefore the study of snps in ethnic groups is important for establishing the clinical significance of the screening of these polymorphisms. the main goal of the research is to study the polymorphisms of cyp2c9 , cyp2c19 , vkorc1 , and slco1b1 in yakuts. genomic dna from 229 yakut subjects we...

Glutathione S-transferases (GSTs; EC: 2.5.1.18) are ubiquitous multifunctional enzymes, which play a key role in cellular detoxification. Functional genetic polymorphisms in genes encoding GSTM1 (a member of GST class mu; OMIM: 138350), and GSTT1 (a member of GST class theta; OMIM: 600436) have been well defined. The functional null alleles of GSTM1 and GSTT1 represent deletions of GSTM1 and GS...

The status of genetic diversity, adaptation to climate change or the identification genes associated with traits interest in livestock populations has been a major concern for scientists last decades. Biotechnology evolved continuously, offering new tools and methodologies analyse genomes species. Biochemical markers protein polymorphisms were used population studies many years ago, but over th...

chemokines and their receptors  play an important  role in the  late inflammatory stage of asthma. in this study, we aimed to investigate polymorphisms of mcp-1 (ccl2), ccr2 and ccr5 which can affect qualitatively and/or quantitatively their production and thus influence both susceptibility and severity of asthma and its clinical and biological features. mcp-1   (a/g   -2518),  ccr2   (+/64i), ...

Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...

objective(s):to the best of our knowledge, this is the first report on the contributions of gst genetic variants to the risk of diabetic retinopathy in an iranian population. therefore, the objective of this study was to determine whether sequence variation in glutathione s-transferase gene (gstm1 and gstt1) is associated with development of diabetic retinopathy in type 2 diabetes mellitus (t2d...
