UNLABELLED The long-term protection of hepatitis B (HB) vaccination has been debated for years. The purpose here was to evaluate the kinetic changes of antibody to HB surface antigen (anti-HBs) and define immune memory of the HB vaccine among college students who had previously received full neonatal immunization against HB. In all, 127 college students aged 18-23 years born after July 1984 who...

Available data suggest that snake hemoglobins (Hbs) are characterized by a combination of unusual structural and functional properties relative to the Hbs of other amniote vertebrates, including oxygenation-linked tetramer-dimer dissociation. However, standardized comparative data are lacking for snake Hbs, and the Hb isoform composition of snake red blood cells has not been systematically char...

Objectives: To assess the antibody level against hepatitis B surface antigen (anti-HBs) among newborns and their mothers and among recently vaccinated infants at age of 9 and 12 months. It also aimed at assessing the long-term immunity to hepatitis B among vaccinated children aged 6–11 years according to Egyptian expanded immunizing protocol. Methodology: Total no of 323 vaccinated healthy infa...

Vickers indentation was used to evaluate the hardness and apparent fracture toughness of unirradiated irradiated UO2 fuels, with objective determine effects irradiation on mechanical properties. Indentation tests were realized at room temperature standard doped in a pressurised water reactor up burnup 81.6 GWd/tM. For highest burnups, fuels had restructured high structure (HBS) periphery pellet...

INTRODUCTION This study aimed to evaluate the response to hepatitis B (HB) revaccination of healthcare workers (HCW) who are negative for antibodies to HB surface antigen (anti-HBs) after a complete vaccination series. METHODS HCW whose anti-HBs test was performed > 90 days after a HB vaccination course were given a 4th dose. A post-vaccination test was done within 30 to 90 days. RESULTS On...

colonial times_ Atthough there are great inter-tribal variations in SGT, the HbS gene has been reported from nearly all subSaharan African countries including the neighbouring ocean islands, except the mainly Cushite Ethiopia and Somalia.io'o Recent studies have shown the gene to be present in tribes in which it was originally found to be absent 30 years ago." This type of change in the HbS spr...

Hepatitis B surface antigen (HBsAg) and antibodies to both the surface and core antigens of the hepatitis B virus (anti-HBs and anti-HBc) have been studied in 64 consecutive cases of fulminant hepatitis. HBsAg was detected by counterelectrophoresis in 23 (35-9 %) but by radioimmunoassay in 38 (59-3 %). Anti-HBs was detected by passive haemagglutination in 26 (40-6 %), coexisting HBsAg and anti-...

Background: Hemangioblastomas (HBs) are benign neoplasms of the central nervous system (CNS) that account for 10–15% of posterior fossa tumors in adults. HBs most commonly arise in the cerebellum but also occur in the spinal cord and medulla. They occur sporadically as solitary lesions or in association with von Hippel-Lindau (VHL) disease and are usually multiple. HBs can arise in the supraten...

BACKGROUND Hepatitis B vaccination, recommended for medical staff, has a non-response rate of 5% to 32%. In Poland, there is no standardized postvaccination protocol to verify immunity. OBJECTIVES To determine the fraction of those who have been vaccinated against HBV (with a complete course followed/not followed by a booster) but not checked for serological evidence of hepatitis B immunity a...
