During an outbreak of hepatitis B virus (HBV) infection in a hemodialysis unit, patients were assessed for serological viral markers and vaccination status. HBV infection was identified in 26 patients. Twenty of these were positive for hepatitis B surface antigen (HBsAg), and 6 were negative for HBsAg but positive for IgM antibody to hepatitis B core(More)
Hepatitis B serological studies were carried out in 251 asymptomatic carriers of HBsAg living in an endemic rural area of Cachoeiro do Itapemirim (545 km distant from Rio de Janeiro) in order to evaluate this population as a potential source of blood plasma for hepatitis B vaccine production. A pilot study on HBsAg purification from plasma was also(More)
BACKGROUND It is crucial to know the demands on basketball referees, in different match periods (MPs) and phases of competition, for planning referee training and subsequent successful refereeing. OBJECTIVE To measure and evaluate the distance covered by referees in a match by measuring the number of interruptions, percentage of heart rate (%HR), and(More)
By the method of affinity chromatography a partially purified antigen was obtained after passing the plasma of an asymptomatic carrier of HBsAg through a column of Sepharose 4B linked to angi-HBs. This antigen was inoculated in rabbits using a schedule of 1,0 mg in the first dose and 4 other doses of 0,5 mg with intervals of approximately 15 days. Observing(More)
AIM The dynamics of Basketball refereeing has changed and more recently the championships started to use the participation of three referees, but there is still a lack of information about the physical characteristics and performance of the referees. The aim of this study was to characterize the neuromuscular and metabolic performances and body composition(More)
A previous seroepidemiological study in the rural zone of Vargem Alta (ES) SouthEast of Brazil, showed a prevalence of up to 9% of hepatitis B surface antigen (HBsAg) in some areas. One hundred susceptible children aging 1 to 5 years old were selected and immunized with a recombinant DNA hepatitis B vaccine (Smith-Kline 20 mcg) using the 0-1-6 months(More)
