conclusions association with sex, genotype and clinical symptoms revealed that the pre-s1 orf deletion occurred in 40% , 40%,and 20% of genotypes b,c, and d respectively, and 80% of the female population, of which all but one were diagnosed with chronic hepatitis b. additionally, several mutations were found in the bcp region with the following incidence rate; c1653 t (8.6%), a1752 g (10.8%),17...

background: to study methaemoglobin content and nadh-methaemoglobin reductase activity of three human erythrocyte genotypes (hbaa, hbas and hbss).materials and methods: studies to ascertain methaemoglobin concentration and level of nadh-methaemoglobin reductase activity of three human erythrocyte genotypes (hbaa, hbas and hbss) were carried out in forty-three (43) healthy male participants of c...

aim : the purpose of this study was to compare the distribution of interleukin (il)-28b genotypes between iranian healthy individuals and patients with chronic hepatitis c based on the genotype. background : polymorphisms in the region of il-28b gene have been identified as the strongest genetic pretreatment predictor of sustained virological response (svr) in hepatitis c infection. patients an...

background: transforming growth factor-beta 1(tgf-β1) t869c (rs1800470, the same below) gene polymorphism is notably relative with the development of diabetic nephropathy (dn)，and cc/ct genotype diabetic have higher frequency of than tt genotype diabetic. to find out individual risk factors in the two genotypes especially in susceptible genotype could provide more efficient and targeted prevent...

Background The interaction between genetic, epigenetic and environmental factors plays an important role in the aetiology of hypertension. GWAS observational studies link C677T polymorphism methylenetetrahydrofolate reductase (MTHFR) with hypertension, while riboflavin, MTHFR cofactor, has been shown to reduce blood pressure global DNA methylation homozygous (TT genotype) individuals. It is cur...

results the highest prevalent genotype was genotype 4a, which was found in 57 patients (92%) followed by 2 isolates (3%) with genotype 4o, 2 strains (3%) with genotype 1g and one isolate (2%) with genotype 4n. conclusions this molecular epidemiology study revealed high prevalence of hcv genotype 4, subtype 4a among egyptian patients residing in sharkia governorate, egypt. patients and methods t...

main objective in wheat breeding programs is to improve high yielding and stable varieties possessing desirable morpho-physiological traits. this study was conducted to determine the stability of 18 winter and facultative bread wheat genotypes. the experiments carried out in 9 experimental stations (karadj- arak- ardebil- jolgerokh- miandoab- hamedan- mashad- qazvin- khoy) using a randomized co...

Theory suggests that iteroparity may confer greater fitness than semelparity in situations in which temporal environmental variation is high and unpredictable. Variable age-specific mortality, density dependence, and other factors may also favor iteroparity over semelparity. Here, we empirically test the adaptive benefits of greater numbers of reproductive years in a study of reproductive sched...
