Background: SEN virus (SENV) is the latest virus proposed as a cause of unknown hepatitis cases. Among nine detected genotypes of the virus, genotypes D and H are more frequent in hepatitis cases of unknown origin. The aim of this study was to determine the frequency of SENV-D and SENV-H genotypes in the sera of healthy individuals and hepatitis B and C patients. Methods: Totally, 200 serum sam...

This study assessed the seroepidemiology of Toxoplasma gondii, Hepatitis B Virus and their co-infection infection in women of child-bearing age in communities in Osun State, Nigeria. The study also determines the factors that facilitate the organisms among the studied groups and possible interaction between the prevalence of infection and the risk factors. These were done with a view to providi...

BACKGROUND AND AIM: Hepatitis B Virus (HBV), a DNA virus with a human-only reservoir, is a worldwide public health problem. Approximately 45.0% of the world’s population is considered to live in areas of high endemicity with a lifetime risk of infection of more than 60.0%. The present study aimed to assess the level of understanding and awareness about Hepatitis B immunization among the first a...

hepatitis b virus (hbv) dna polymerase transactivated protein 1 (hbvdnaptp1) is a novel protein transactivated by hbv dna polymerase, screened by suppression subtractive hybridization technique (genbank accession no: ay450389). the biological function of hbvdnaptp1 was investigated in this study.we constructed a vector pcdna3.1 (-)/myc-his a-hbvdnaptp1 and used it to transfect acute monocytic l...

background: recently, some new viruses have been identified for their association with hepatitis which torque teno mini virus being among them. the aim of this study was to determine the frequency of torque teno mini virus in healthy individuals and hepatitis b and c patients in isfahan, iran. materials and methods: one hundred serum samples of healthy individuals from isfahan blood transfusion...

Post-translational modifications of proteins control many biological processes. This is also important process in virus including hepatitis B. However, there is no in-depth study on the whole hepatitis B virus large envelope protein. In this work, potential protein post-translational modifications in hepatitis B virus large envelope protein were determined by a standard bioinformatics technique...
