... (HCC). Objective: The aim of this study was to determine the association among HCC, OPN, and HBV. Methods: Two hundred and forty-one subjects were recruited and divided into 6 groups: healthy controls, asymptomatic HBsAg carriers, HBsAg (−) patients with other tumors, HBsAg (+) chronic liver disease...

..., Upper Egypt. Methods: HBsAg and HBeAg were examined by ELISA while HBV-DNA was examined by PCR. HBV genotyping was conducted by restriction fragment length polymorphism. Results: HBsAg was detected in 237 donors (1.98%). The HBV-DNA of 50 donors with the highest HBsAg OD was examined for the HBV...

...Colin R. Howard; Lisa M.C. Allison Hepatitis B surface antigen (HBsAg) particles consist predominantly of a glycoprotein of 226 amino acids which bears the B-cell epitopes important for the induction of protective antibody responses in humans. It has been clearly shown that the region between...

...M. Irshad; B.M. Gandhi; S.K. Acharya; B.N. Tandon The binding between hepatitis B surface antigen (HBsAg) and polymerized human serum albumin (poly-HSA) was studied in HBsAg-negative (25) and HBsAg-positive (92) sera by a sensitive enzyme-linked immunosorbent assay technique, and a correlation...

...T. Kremastinou; C.R. Howard; J. Skelly; A.J. Zuckerman Adult male guinea pigs were immunized with hepatitis B virus polypeptides prepared by Triton X-100 solubilization of purified 22-nm hepatitis B surface antigen (HBsAg) particles. A virus-specific subunit containing both the 28,000 molecular...

...Robert Neurath; Nathan Strick A radioimmunoassay for albumin-binding sites associated with hepatitis B surface antigen (HBsAg) is described. Polystyrene beads coated with glutaraldehyde-polymerized human serum albumin were incubated with diluted specimens of HBsAg-positive sera which contained...

...Ting Wu; Min Chen; Shan-Hai Ou; Tong Cheng; Jun Zhang; Ning-Shao Xia Aims: To evaluate the immune responses induced by different combined immunizations of HBsAg protein vaccine (P), recombinant vaccinia virus vaccine (V) and DNA vaccine (D). Methods: Balb/c mice were primed by one of the three...
