BACKGROUND In this study, we evaluated the performance of Elite microplate analyzer (Bio-Rad Laboratories, France) and the related assays (ULTRA line) for the detection of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). METHODS Seroconversion panels, HBsAg positive/HBsAg negative (n=99/n=1,422), anti-HCV positive/negative (n=97/n=1,670), and anti-HIV p...

Platelet aggregation indicating antigen-antibody complex formation was observed when hepatitis B surface (HBs) antigen and antibody were mixed. Platelet aggregation titers were determined for serum specimens found positive by radioimmunoassay for either HBs antigen or HBs antibody. From these determinations, incidence of HBs antigen-antibody complexes was found to be higher in HBs antigen seraa...

The aim of this study was to compare the sensitivity and specificity of morphine-augmented hepatobiliary scintigraphy (MA-HBS) with that of conventional hepatobiliary scintigraphy (C-HBS) for acute cholecystitis. The results of most MA-HBS studies cannot be compared with C-HBS estimates, since articles describing C-HBS often include non-candidates for MA-HBS. However, using meta-analytic techni...

BACKGROUND Passively acquired maternal antibodies in infants may inhibit active immune responses to vaccines. Whether maternal antibody against hepatitis B surface antigen (anti-HBs) in infants may influence the long-term immunogenicity of hepatitis B vaccine remains unknown. METHODOLOGY/PRINCIPAL FINDINGS Totally 338 pairs of mothers and children were enrolled. All infants were routinely vac...

Sickle hemoglobin (Fe(II)HbS) reconstituted with nickel(II)protoporphyrin IX yields an artificial hemoglobin (Ni(II)HbS), the first heme-substituted hemoglobin shown to mimic the polymerization of deoxyHbS. Unlike Fe(II)HbS, Ni(II)HbS does not bind oxygen and therefore polymerizes under aerobic conditions. While the polymer solubility coefficient (Csat) for Ni(II)HbS is elevated about 2 g/100 m...

In Taiwan, infants need to receive 3 doses of hepatitis B virus (HBV) vaccine under the public health policy from the government. However, there are many young adults who even though received complete HBV vaccination in their childhood would lose the positive response of anti-hepatitis B surface antibody (HBs) and need the booster dose of HBV vaccine. The aim of our study is to determine the po...
