Non invasive immunologic markers of virus-induced liver disease are unmet needs. We tested the clinical significance of quantitative total and IgM-anti-HBc in well characterized chronic-HBsAg-carriers. Sera (212) were obtained from 111 HBsAg-carriers followed-up for 52 months (28-216) during different phases of chronic-HBV-genotype-D-infection: 10 HBeAg-positive, 25 inactive-carriers (HBV-DNA≤2...
Several studies have reported that antibody to hepatitis B core antigen (anti-HBc) positivity may influence the development of hepatocellular carcinoma (HCC) in chronic hepatitis C patients, but the evidence is still not conclusive. In this study, we examined whether the presence of anti-HBc positive was associated with the development of HCC in hepatitis C virus (HCV)-infected subjects among t...
Routine use of the automated chemiluminescent microparticle immunoassay Abbott ARCHITECT anti-HBc for diagnosis of hepatitis B is limited in case of borderline reactive sera with low signal close to the cut-off index. In order to determine the significance of anti-HBc detection when borderline reactivity occurs using the ARCHITECT anti-HBc assay, a comparative study was designed. 3540 serum sam...
Studies regarding the clinical significance of quantitative hepatitis B core antibody (anti-HBc) in patients with chronic hepatitis B receiving first-line nucleos(t)ide analogues is limited. The aim of this study was to determine the performance of anti-HBc as a predictor for hepatitis B e antigen (HBeAg) seroconversion in HBeAg-positive CHB patients treated with entecavir. This was a retrospec...
Abstract Petung bamboo (Dendrocalamus asper) stem-based hematite-biochar composite (HBC) has been synthesized using microwave-assisted pyrolysis (MAP) to replace conventional pyrolysis. The sawdust contains 19.8-26.6% lignin and cellulose as much 4.24-5.36% so that it can be used precursors in biochar preparation. In general, bamboo-based a low adsorption capacity. this study, was modified by h...
Exclusion of liver grafts from hepatitis B core antibody (anti-HBc) positive donors to prevent de novo hepatitis B virus (HBV) infection after liver transplantation is not feasible in areas highly endemic for HBV virus like Taiwan, where approximately 80% of adults are anti-HBc(+). The efficacy of lamivudine monotherapy to prevent de novo HBV infection after living donor liver transplantation (...
Activated immune cells release cytokines which modulate the activity of bone cells in vitro. Expression of major histocompatibility complex (HLA in humans) class II determinants on bone surface cells may be important in local immune cell activation. In this study, expression of HLA-DR and DQ by cultured human bone cells (HBC) derived from normal trabecular bone surfaces was assessed by fluoresc...
Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the only m...
A recent study revealed that quantitative hepatitis B core antibody (qAnti-HBc) level could serve as a novel marker for predicting treatment response. In the present study, we further investigated the predictive value of qAnti-HBc level in HBeAg-positive patients undergoing PEG-IFN therapy. A total of 140 HBeAg-positive patients who underwent PEG-IFN therapy for 48 weeks and follow-up for 24 we...
UNLABELLED Multiple subunits of the hepatitis B virus (HBV) core protein (HBc) assemble into an icosahedral capsid that packages the viral pregenomic RNA (pgRNA). The N-terminal domain (NTD) of HBc is sufficient for capsid assembly, in the absence of pgRNA or any other viral or host factors, under conditions of high HBc and/or salt concentrations. The C-terminal domain (CTD) is deemed dispensab...
