Background and Aims: Occult hepatitis B virus infection (OBI) is known as an important source of hepatitis B virus (HBV) infection. It is categorized as Hepatitis B surface antigen (HBsAg) not being present and low DNA viral load in serum. In this study, an attempt was made to investigate the outbreak of anti-HBc and OBI among the HBsAg-negative donors in Golestan province. Materials and Metho...

introduction: hepatitis c virus (hcv) is the major cause of acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma worldwide. because of increasing number of infected patients throughout the world, various studies are concentrated on development of high quality diagnostic tests and genotyping in various regions of the world. methods: in this study, we used rt-pcr to isolate and a...

BACKGROUND Acute viral hepatitis is most frequently caused by the hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV). OBJECTIVES To determine seroprevalence of HAV, HBV, HCV and HEV among patients with acute hepatitis in Nairobi, Kenya, elucidate various risk factors for hepatitis viral infection and determine the co-...

Successful viral infection requires intimate communication between virus and host cell, a process that absolutely requires various host proteins. However, current efforts to discover novel host proteins as therapeutic targets for viral infection are difficult. Here, we developed an integrative-genomics approach to predict human genes involved in the early steps of hepatitis C virus (HCV) infect...

• Jam formation in traffic flow on a highway with some slowdown sections, • Modelling how ribavirin improves interferon response rates in hepatitis C virus infection,

the hepatitis g virus (hgv) is a newly discovered rna virus, which is associated with acute or chronic hepatitis. a survey was conducted in thalassemic patients, intravenous drug users (ivdu) and blood donors aiming to investigate the prevalence of hepatitis g virus (hgv) infection in these groups in tehran. the presence of hgv rna in these populations was determined using reverse transcriptase...

background hepatitis b virus (hbv) and hepatitis c virus (hcv) infections are among the most important health issues in turkey. human immunodeficiency virus (hiv) infections are less frequently observed in the country. the individuals who had blood transfusions, patients undergoing hemodialysis, and intravenous drug addicted individuals, people who had tattoos/piercings, communal living environ...

Background: Hepatitis is among the major health problems, especially in developing countries. During past decades, the association between type of blood group (ABO) and hepatitis B and C virus has always been discussed. This study was designed to investigate the possible association between type of ABO blood group and chronic hepatitis B and C infection. Methods: In the present analytical stud...

context several risk factors play the role in the development of hepatocellular carcinoma (hcc) from which chronic hepatitis b and c infections are the most important ones. dna integration of hepatitis viruses alters the function of critical genes promoting malignant transformation of virus-infected liver cells. evidence acquisition there are remarkable geographic differences in prevalence of c...
