Background: Approximately 600,000 deaths occur every year as a result of the acute and chronic consequences of hepatitis B virus infection. Ten different hepatitis B virus genotypes have been identified with distinct geographical distributions. Different clinical outcomes, including the rate of mutations, development of hepatocellular carcinoma, chronicity, response to treatment, transplantatio...

background: hepatitis b virus (hbv) gene and protein variations are frequently been seen in chronic patients. the aims of study were to determine the genotypes as well as the patterns of variations distribution in chronically-infected patients from the central part of iran. methods: the surface gene was amplified, sequenced and subsequently aligned using international and national iranian datab...

objective(s) the aim of this study was to characterize the hepatitis b virus surface protein genotypes and sequence variations among hepatitis b virus surface antigen (hbsag) positive chronic patients in hormozgan province, south of iran. materials and methods a total of 8 patients enrolled in this study. the surface gene was amplified and directly sequenced. genotypes and nucleotide/amino acid...

background: to evaluate vdr gene variation and its interaction with immune regulatory molecules in osteoporosis. methods: totally 205 pre and postmenopausal women were recruited in the study. after an overnight fast, peripheral blood was taken and centrifuged to sprat serum for measurement of serum parathyroid hormone, 25 hydroxyvitamin d, osteocal­cin and cross laps. the fok i polymorphism in ...

The variants of angiotensin converting enzyme (ACE) and matrix metalloproteinases (MMPs) genes might be involved in the pathogenesis of end stage renal disease (ESRD) and hypertension. We studied the ACE insertion/deletion (I/D) and MMP-7 A-181G variants in 99 unrelated ESRD patients and 117 individuals without renal complications from Western Iran with Kurdish ethnic background. The frequency ...

the activity of angiotension converting enzyme (ace; omim: 106180) in different brain regions of patients with schizophrenia changed, suggesting a possible involvement of ace in psychiatric disorders. genetic polymorphism of insertion/deletion (i/d; dbsnp rs4646994) in the gene encoding ace has been well defined.the present case-control study was performed on 363 (268 males, 95 females) in-pati...

In order to identify the effects of different levels of nitrogen fertilizer on seed yield and seed growth indices of some bread and durum wheat genotypes, a field experiment was conducted in 2013-2014 in Khuzestan Agricultural and Natural Resource Research Center. The experiment was designed as a split plot with three replications. Nitrogen application rates (50, 100 and 150 kg N.ha-1) were ass...
