objective: in this project, our aim was to construct a novel expressing vector harboring a new sequence from overlapping region of ns3 gene of hcv from infected iranian patient. materials and methods: the partial ns3 (pns3) gene was amplified by nested-rt-pcr method using sera of hcv infected patients harboring genotype 1a. after purification and cloning the pns3 into ta-cloning vector, the be...

Today, chronic viral hepatitis is considered as a public health problem in the world. Totally, 5% of the world population, especially in Asia and Africa suffer from this problem. The prevalence of acute hepatitis in America is 0.1-0.2 percent, 50% of those with hepatitis C (HCV) and 5-10% of them with hepatitis B (HCV) develop chronic hepatitis. Determining HBV and HCV genotypes is important to...

The present study corroborates the annual average economic burden of Hepatitis C virus (HCV) and socio-economic factors concerning awareness HCV in Pakistan.

Background: Hepatitis C virus infection (HCV) is a main health problem in our country. It is thought that the transmission of hepatitis C virus (HCV) through the endoscopic procedures is a rare event. The aim of this study was to evaluate the risk of conventional disinfection in the transmission of HCV. Materials and methods: A prospective study, comprising 456 consecutive upper gastrointestin...

background and aims: viral hepatitis is a global health problem with a high mortality rate. recently, a new flavi-like virus, provisionally named hepatitis g virus (hgv), has been described. hgv does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (pc...

Background: Hepatitis C virus (HCV) is a blood-borne virus. It is a major global public health problem and can cause both acute and chronic hepatitis. The aim of this study was to report the epidemiological features of HCV infection and risk factors based on the data from Azar Cohort, East Azerbaijan province, Iran. Methods: The population of this study comprised the people in the age range of...

Nowadays viral hepatitis is one of the most common and important causes of chronic liver disorders in the world. Extrahepatic manifestations of viral hepatitis consist a main part of the disease. The main viruses causing hepatitis include Hepatitis A, B and C viruses. Herein common skin manifestations in hepatitis C virus (HCV) are discussed. Chronic hepatitis causes skin disorders both directl...

background: to evaluate the prevalence of hepatitis c by antibody testing, hcv-rna detection by pcr and relative risk fac­tors of hcv infection among hd patients and staff members in markazi province/iran. the other purpose was to deter­mine genotypes of hcv in this population. methods: the study group consisted of 204 hd patients and 47 staff members from all 9 dialysis centers in markazi prov...
