EXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE
The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...

The clinical course and biochemical and histological findings in the HBAg-positive and the HBAg-negative cases were similar, suggesting that HBAg-positive chronic liver disease...
متن کاملA Retrospective Study on the Significance of Liver Biopsy and Hepatitis B Surface Antigen in Chronic Hepatitis B Infection
To investigate changes in the HBV replication level along with the natural course of chronic HBV infection and to examine the accuracy of the immune tolerant phase defined by the serological profile.A total of 390 chronic HBV-infected patients were retrospectively recruited for this study. They were classified into immune-tolerance (IT), immune-clearance (IC), low-replicative (LR), and HBeAg-ne...

A high frequency of HB Ag-positive hepatitis cases was also found among homosexuals (Vahrman, 1973) and evidence has been presented that hepatitis B may spread between sexual partners (Hersh, Melnick, Goyal, and Hollinger, 197...
متن کاملTelbivudine vs tenofovir in hepatitis B e antigen-negative chronic hepatitis B patients: OPTIMA roadmap study
AIM To make efficacy and safety comparison of telbivudine-raodmap and tenofovir-roadmap in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients. METHODS This was the first prospective, randomised, two-arm, open-label, non-inferiority study in HBeAg-negative CHB patients that compared telbivudine and tenofovir administered as per roadmap concept. Patients were treated up t...
