BACKGROUND Clostridium difficile is a primary cause of antibiotic-associated diarrhea that typically develops when gut microbiota is altered. Conventional treatment for C. difficile infection (CDI) is additional antimicrobial administration, which further disrupts normal intestinal microbiota, often resulting in poor treatment outcomes. METHODS A pregnant dairy cow was repeatedly immunized wi...

Viral hepatitis is the most common cause of serious health problems such as liver cirrhosis and hepatocellular carcinoma (HCC). Leading to immunodeficiency disorders through different mechanisms, Human Immunodeficiency Virus (HIV) causes the development of severe secondary infections. Hepatitis A (HAV) is thought to spread by the faecal-oral route, while Hepatitis B (HBV), Hepatitis C (HCV) and...

BACKGROUND Prevalence of total antibodies against core antigen (anti-HBc) of hepatitis B virus (HBV) is greater in longer dialysed patients, but there are no data indicating a relationship between the higher seroconversion rate to anti-HBc positivity and longer renal replacement therapy (RRT) vintage prior to seroconversion. Our aim was to evaluate the association between RRT duration and seroc...

Hepatitis B virus (HBV) core protein (HBc) can shuttle between nucleus and cytoplasm. Cytoplasm-predominant HBc is clinically associated with severe liver inflammation. Previously, we found that HBc arginine-rich domain (ARD) can associate with a host factor NXF1 (TAP) by coimmunoprecipitation. It is well known that NXF1-p15 heterodimer can serve as a major export receptor of nuclear mRNA as a ...

A meta-analysis was performed to ascertain to what extent hepatitis B surface antigen (HBsAg)-negative/anti-hepatitis B core (anti-HBc)-positive subjects with chronic liver disease are at a higher risk of developing hepatocellular carcinoma (HCC) than the anti-HBc-negative.All studies included had to fulfill the following characteristics and inclusion criteria: they investigated the relationshi...

BACKGROUND The risk of transmitting a hepatitis B virus (HBV) infection from donor kidneys with a past HBV serological profile may be negligible. Data on HBV transmission to kidney transplant recipients from donor organs that were anti-HBc/HBsAg in Italy has not been previously reported. Anti-HBc testing in cadaver organ donors has been mandatory in Italy since 2002, when anti-HBc determination...

BACKGROUND & AIMS Although hepatitis B virus (HBV) transmission after liver transplantation of grafts from HBsAg-negative, anti-HBc positive donors is well established, the growing organ shortage favours the use of such marginal grafts. We systematically evaluated the risk of HBV infection after liver transplantation with such grafts and the effect of anti-HBV prophylaxis. METHODS We performe...

For several decades, carbon fibers have been used for lightweight engineering in aircraft automotive and sports industries, mostly based on high-quality polyacrylonitrile (PAN). We investigated a novel PAN-based precursor fiber (PF) modified with polycyclic aromatic hydrocarbon, namely hexabenzocoronene (HBC), which is expected to improve the thermal conversion process create (CF) enhanced mech...

It remains unclear what determines the subcellular localization of hepatitis B virus (HBV) core protein (HBc) and particles. To address this fundamental issue, we have identified four distinct HBc localization signals in the arginine rich domain (ARD) of HBc, using immunofluorescence confocal microscopy and fractionation/Western blot analysis. ARD consists of four tight clustering arginine-rich...

the transfusion transmitted infections are potentially dangerous complications of transfusion therapy in immunocompromised patients. the aim of this study was to determine the prevalence of transmissible infections in blood donor population in kashan, iran. a total of 600 consecutive sera were tested for cmv-igm antibody, hbsag, hepatitis b core (hbc) antibody, hepatitis c (hcv) antibody, and h...
