Hepatitis B virus (HBV) reactivation (HBVr) in recipients of allogeneic hematopoetic stem cells (aHSCs) appears heterogeneously with respect to its frequency, manifestation, and outcome. The aim of this study was to present data from a large German cohort of recipients of aHSC transplantation (aHSCT), focusing on the incidence of HBVr in antibody to hepatitis B core antigen (anti-HBc)-positive ...

conclusions the current study found a relatively high frequency of positivity gbv-c-exposure among the patients receiving hemodialysis in the area understudy. nosocomial transmission seems to be the main route of gbv-c infection in the area. objectives the current study aimed to evaluate gbv-c infection among hemodialysis patients. patients and methods totally, 149 patients receiving hemodialys...

The objective of this study was to evaluate the prevalence of hepatitis B and C viruses in a group of HIV infected patients, followed at a single institution since 1996. 1,693 HIV positive patients (1,162 male, 531 female) were tested for HBV infection. Virological markers for HBV included HBsAg and total anti-HBc by ELISA. 1,457 patients (1,009 male, 448 female) were tested for HCV infection. ...

Tests for Igm antibody to hepatitis B core antigen (anti-HBc IgM) are useful diagnostic tools in the evaluation of patients with hepatitis B virus (HBV) infection. A m ethod is described for detecting anti-HBc IgM based on application of a commercially available radioimmunoassay for total antiHBc to column separated serum IgM and the technique is evaluated in patients with acute and chronic HBV...

BACKGROUND Viral hepatitis is a serious global public health problem affecting billions of people globally, and both hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are rapidly spreading in the developing countries including Bangladesh due to the lack of health education, poverty, illiteracy and lack of hepatitis B vaccination. Also there is lack of information on their prevalenc...

BACKGROUND Universal anti-hepatitis-B vaccination of infants and adolescents was implemented in Italy in 1991. We undertook a multicentre study in previously vaccinated individuals to assess the duration of immunity and need for booster, over 10 years after vaccination. METHODS In 1212 children and 446 Italian Air Force recruits vaccinated as infants and adolescents, respectively, we measured...

The native extracellular matrix (ECM) is composed of a cross-linked porous network of multifibril collagens and glycosaminoglycans. Nanofibrous scaffolds of silk fibroin (SF) and hydroxybutyl chitosan (HBC) blends were fabricated using 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) and trifluoroacetic acid (TFA) as solvents to biomimic the native ECM via electrospinning. Scanning electronic microscop...

Reactivation of the hepatitis B virus (HBV) can cause severe liver injury resulting in jaundice, liver failure, and death.1 This outcome continues to occur in patients receiving immunosuppressive drug therapy (ISDT) despite the ability to identify persons at risk with readily available and inexpensive blood tests for hepatitis B surface antigen (HBsAg) and antibody to hepatitis B core antigen (...

HBV core protein (HBc), the major component of nucleocapsid is known to have an essential role in the virus life cycle as the transporter of virus genome to the host nucleus; however, molecular details of the intracellular transport of HBc remain unknown. In this study, we investigated the intracellular distribution of the HBc protein resulting from Semliki Forest virus (SFV)-driven HBc gene an...

Despite extensive public health efforts, there are presently 200 to 400 million malaria infections and 1 to 2 million deaths each year due to the Plasmodium parasite. A prime target for malaria vaccine development is the circumsporozoite (CS) protein, which is expressed on the extracellular sporozoite and the intracellular hepatic stages of the parasite. Previous studies in rodent malaria model...
