multiple sclerosis (ms) is a demyelinating neuro- inflammatory autoimmune disease of the central nervous system. genetic predisposition has long been suspected in the etiology of this disease. the association between mthfr polymorphisms and ms has been ivestigated in different ethnic groups. we investigated the association between mthfr c677t and a1298c missense variants and ms in 180 patients ...
background and objective: haemophilus influenzae type b (hib) is divided into two distinct genotypes, type i and type ii, based on the structure of capsular polysaccharides. the capsulation locus of haemophilus influenzae type b consists of three functionally distinct regions, designated regions 1 to 3. region iii contains hcsa and hcsb genes; however, notable sequence variation in this region ...
conclusions more than one-quarter of treatment-experienced patients with hcv genotype 3 achieved svr after re-treatment with consensus interferon plus ribavirin. objectives we aimed to assess the efficacy and safety of cifn and ribavirin in non-responders and relapsers to pegylated interferon with ribavirin therapy. patients and methods this open-label investigator-initiated study included 44 p...
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...
The results of the studies showed that by prolactin gene (PRL), highest yield was found in first-calf heifers with PRLBB genotype 4.7% -10.5% as compared to herd-mates other genotypes; and cows second third lactations – PRLAB 2.6-10.6%. In terms milk fat, animals had a higher rate than PRLAA genotypes 0.04-0.17 pp, especially lactation having most noticeable changes. By beta-lactoglobulin (BLG)...
Japanese encephalitis (JE) is an important viral with epidemic status in Asia, which caused by virus (JEV), a member of the genus Flavivirus . JEV divided into five genotypes. Genotype 5 (G5) relatively neglected because limited number cases and strains isolated. The first strain G5 (Muar strain) was isolated Singapore 1952 patient from Muar, Malaysia. second (XZ0934) 57 years later China, thus...
Selection of adapted genotypes with high seed yield and yield stability is the goal of soybean breeding programs. To evaluate the adaptability and seed yield stability of soybean promising lines, 19 promising lines and cv. Williams as check were evaluated using randomized complete block design with four replications in four locations: Karaj, Gorgan, Moghan and Khoramabad in Iran during two grow...
Background: Human respiratory syncytial virus (HRSV) is the most important viral agent of acute lower respiratory tract disease in infants and young children worldwide. This virus is responsible for 50% brochiolitis and 25% pneumonia in infants. There are limited data of molecular epidemiology of HRSV from developing countries. This is the report on the molecular epidemiology of human respirato...
Background: One of the most important causes of chronic liver disease is hepatitis C virus (HCV), which causes liver cirrhosis and hepatocellular carcinoma. To control the prevalence of the disease, knowledge and information in risk factor of HCV are required. The aim of this study was to compare the risk factors of infection between HCV patients with genotypes 1a and 3a. Methods: This is an o...
