Thyroxine Binding by Hepatitis B Surface Antigen

Journal of Infectious Diseases, 1975
Thyroxine and triiodothyronine binding sites are present on the 20-nm spherical particles associated with hepatitis B surface antigen (HBsAg). Thyroxine-treated HBsAg has a buoyant density of 1.26 g/cm-3 in CsCl and appears under the electron microscope as a hexagonal particle with a center-to-vertex distance of 10 nm.

Hepatitis B surface antigen in spinal fluid

Medical and Pediatric Oncology, 1980
AbstractHepatitis B surface antigen (HBsAg) was detected in the cerebrospinal fluid (CSF) of five of nine leukemia patients with HBsAg‐positive sera. These five CSF samples were shown to be free of occult blood using a sensitive hemoglobin extraction technique.

Signals regulating hepatitis B surface antigen transcription

Nature, 1983
About 200 million people are chronic carriers of hepatitis B surface antigen (HBsAg), but since hepatitis B virus (HBV) cannot be propagated in vitro, HBsAg transcription has been studied only in cell lines containing HBV DNA integrated into chromosomes, and HBsAg-related mRNAs 2.0 to 2.5 kilobases (kb) long have been described.

Antibodies to Hepatitis B Surface Antigen

Annals of Internal Medicine, 1985
Excerpt To the editor: The article by Kessler and colleagues (1) is of general interest because it shows, once again, that antibodies to hepatitis B surface antigen (anti-HBs), at least as they are...

Concomitant Hepatitis B Surface Antigen and Antibody

Annals of Internal Medicine, 1984
Excerpt To the editor: Recently, Foutch and associates (1) reported the presence of hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs) in 13 patients.

Thermal Inactivation of Hepatitis B Surface Antigen

The Journal of Immunology, 1978
Abstract Thermal inactivation of hepatitis B surface antigen (HBs Ag) was investigated under various experimental conditions by means of a quantitative radioimmunoassay. No decrease of HBs Ag immunologic reactivity could be detected at -80°C, up to 24 months of storage, whereas at -20 and 4°C survival of serum HBs Ag after 6 months was ...

Donors With Hepatitis B Surface Antigen Positivity

Transplantation Proceedings, 2015
There is a still controversy among transplantation centers regarding acceptance of hepatitis B surface antigen (HBsAg)-positive donors for renal transplantation. However, some reports show that these donors can be used under a special protocol. In this study, we compared the clinical and biochemical parameters of patients who received kidneys from ...

Low Hepatitis B Core–Related Antigen Levels Correlate Higher Spontaneous Seroclearance of Hepatitis B Surface Antigen in Chronic Hepatitis B Patients With High Hepatitis B Surface Antigen Levels

Gastroenterology, 2023
Seroclearance of hepatitis B surface antigen (HBsAg) indicates functional cure for hepatitis B virus (HBV) infection. Low HBsAg levels can predict HBsAg seroclearance over time. However, little is known about the association between hepatitis B core-related antigen (HBcrAg) levels and spontaneous seroclearance of HBsAg.We conducted a retrospective ...

Hepatitis B surface antigen (HBsAg) – fibrinogen interaction

Liver, 1984
ABSTRACT— Deparaffinized sections of hepatitis B surface antigen (HBsAg) positive liver biopsies, when incubated in a human fibrinogen solution, reveal a strong labelling of ground‐glass hepatocytes with fibrinogen. This implies an interaction between HBsAg and fibrinogen.

Synthetic Hepatitis B Surface Antigen Peptide Vaccine

1985
A synthetic hepatitis B surface antigen (HBsAg) peptide was prepared containing amino acid residues 122-137 of the major HBsAg polypeptide. This peptide was cyclized by the introduction of an intrachain disulfide bond between cysteine residues at positions 124 and 137 because previous studies had shown that intact disulfide bonds are critical for ...
