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...

This study evaluated the influence of dietary garlic (Allium sativum) extract on survival rate and changes in blood and immune parameters of Common carp (Cyprinus carpio), fed with two different concentrations of aqueous garlic extract after exposure to spring viremia of carp virus (SVCV). The experiments have executed in two steps: Firstly, 270 fingerlings of Common carp with an average weight...

background: to glean insights into the relationship among hepatitis b virus (hbv) genotype/subgenotypes, a1762t/g1764a mutations and advanced liver disease such as liver cirrhosis (lc) and hepatocellular carcinoma (hcc) in southeast china. methods: a case-control study was performed, consisting of chronic hepatitis b (chb) patients (n=160), lc patients (n=150), and hcc patients (n=156). fluores...

conclusions functional renal impairment in diseases caused by hcv was more important than in diseases caused by hbv. the egfr was statistically lower in cirrhosis secondary to hcv than in hcv chronic hepatitis. results hbv chronic hepatitis, hcv chronic hepatitis, and cirrhosis secondary to these viruses were associated with a reduction of the gfr. the egfr was higher in patients with hbv chron...

conclusions overall, we found that obi was rare, but that the prevalence of obi was slightly higher in jiangsu than in other areas of china. methods all donor samples were routinely screened by double enzyme-linked immunosorbent assay (elisa) for hepatitis c virus (hcv), hepatitis b virus (hbv), human immunodeficiency virus (hiv), treponema pallidum (tp), and alanine aminotransferase (alt). sin...

background: hepatitis b virus (hbv) infection causes chronic infection in human population, with high mortality. one of the high risk communities is mentally retarded children, who are institutionalized. special conditions in these centers predispose children for hbv infection and transmission to healthy people. in this study our objective was to determine the prevalence of hbv infection among ...

objective: despite availability of an effective vaccine against hepatitis b virus (hbv), the global prevalence of this virus infection has not diminished significantly. contrary to numerous other human viruses, hbv does not have the ability to propagate in cell culture. however, infectious virus has been produced by transfection of human hepatoma cells with plasmids that contain full length hbv...

conclusions: there are important deficits in adolescents’ knowledge about hbv that requires attention of health educators to tailor educational programs for specific groups. objectives: the aim of this study was to assess iranian adolescents’ knowledge about hepatitis b (hbv) and associated factors. patients and methods: we conducted a questionnaire-based national survey of 18-year-old adolesce...

conclusions the results indicated that there was a positive association between susceptibility to chronic hbv infection and tnf-α polymorphism. in addition, hbv patients carrying -308 gg, -857 cc, and -863 aa genotypes with lower serum levels of tnf-α had an increased risk of infection. background the host genetic background regulates the natural history of chronic hepatitis b virus (hbv) infec...
