In this cross sectional anonymous study, blood samples of 285 dentists and Physicians were tested for hepatitis B surface antigen (HBs Ag), hepatitis B envelope Ag (HBe Ag), antibodies to: hepatitis B suface (anti-HBs), hepatitis B core Ag (anti-HBc) and hepatitis B envelope Ag (anti-HBe) by ELISA-3 and antibody to hepatitis C virus (anti-HCV) by ELISA-3 and immunoblotting tests. The results su...

Sickle cell disease (SCD) is caused by an inherited mutation in hemoglobin that leads to sickle hemoglobin (HbS) polymerization and premature HbS denaturation. Previous publications have shown that HbS denaturation is followed by binding of denatured HbS (a.k.a. hemichromes) to band 3, the consequent clustering of band 3 in the plane of the erythrocyte membrane that in turn promotes binding of ...

A novel approach has been developed for the analysis of hepatitis B virus (HBV) antigenic structure which creates numerical "signatures" of HBV viral strains. This technique employs high affinity IgM and IgG monoclonal antibodies (anti-HBs) directed toward distinct and separate determinants on hepatitis B surface antigen (HBsAg). Such antibodies have been used to develop sensitive and specific ...

BACKGROUND Viral hepatitis caused by hepatitis B virus (HBV) is a leading cause of acute and chronic liver diseases worldwide. OBJECTIVES In Italy, a mandatory vaccination policy was introduced in 1991 and was established for all newborns and 12-year-old individuals. In 2004, vaccination of 12-year old adolescents was discontinued, and that of infants was maintained. PATIENTS AND METHODS We...

BACKGROUND Co-infections of hepatitis B and C viruses are frequent with HIV due to shared routes of transmission. In most of the tertiary care health settings, HIV reactive patients are routinely tested for HBsAg and anti-HCV antibodies to rule out these co-infections. However, using the routine serological markers one can only detect active HBV infection while the occult HBV infection may be m...

conclusions this study shows lower anti-hbs among students who were vaccinated at infancy compared to those vaccinated at older childhood or adolescence. also, subsequent measurement of anti-hbs level at the time of entrance to university is recommended for all previously immunized students. results vaccination coverage rates were 74.1%. about half the participants didn’t show serological evide...

BACKGROUND It is currently recommended that diet of pregnant mothers contain 200-300 mg DHA/day. Aim. To determine whether DHA supplementation during pregnancy and lactation affects infants' immune response. METHODS 60 women in ≥3rd pregnancy studied; 30 randomly assigned to receive DHA 400 mg/day from 12th week gestation until 4 months postpartum. From breast-fed infants, blood obtained for ...

objective: preventing communicable diseases in the armed forces (af) of a country is considered as a national interest and has a great importance. there are limited data on the efficacy of vaccination of the navy personnel. this study was designed to evaluate both the safety and the immunogenicity of a recombinant hepatitis b (hb) vaccine made by pasteur institute of iran (ipi-rhb), in this tar...
