We show that HTLV-1 negative leukemia cells are more sensitive to TQ due to higher levels of drug-induced reactive oxygen species (ROS). PreG1 population in HTLV-1 negative Jurkat and CEM was higher than HTLV-1 transformed ...
Hepatitis D virus (HDV) is a defective RNA virus and its life cycle is dependent on hepatitis B virus (HBV). Worldwide, it is estimated that 15 to 20million individuals are HDV- infected representing approximately 5 percent ...

Introduction: This study aimed to identify reproductive tract infections (RTIs) in married, non-pregnant women, aged 18 to 49 years, living in a low-income suburb of Beirut, and to investigate the relationship between ...
Purpose: Investigation of the injecting drug users (IDUs) population is becoming extremely critical and timely in light of the recent evidence that IDUs now act as the core of hepatitis C virus (HCV) epidemics in developed ...

It is unclear if HIV-1 variants lose the ability to prime naïve CD8+ cytotoxic T lymphocytes (CTL) during progressive, untreated infection. We conducted a comprehensive longitudinal analysis of viral evolution and its ...
The presence of hepatitis B virus (HBV) serological markers have been investigated in 101 Lebanese patients (69 men, 32 women; mean age 32.7 ± 1.7 years) infected with human immunodeficiency virus type 1 (HIV-1). Seven ...

Background: The aim of this study is to determine the prevalence of anti-HCV among injecting drug users (IDUs) in Lebanon, to establish the current prevalence of HCV genotypes in this population and to determine whether ...
Background: The aim of our study was to study the prevalence of and the risk behaviours associated with the hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among two high-risk groups: female sex workers (FSW) ...

It is well established that hepatitis C develops into cirrhosis of the liver and hepatocellular carcinoma (HCC) both of which are fatal diseases. The World Health Organization estimates that there are at least 21.3 million ...
