Monofloral Iranian honeys from eight floral sources were analyzed to determine their anti-HIV-1 activities as well as their effects on lymphocyte proliferation. The Peripheral Blood Mononuclear Cells (PBMCs) used in this study were prepared from five healthy volunteers who were seronegative for HIV, HCV, HBV and TB. The anti-HIV-1 activity of eight different honeys was performed by quantitative...
BACKGROUND Drug-resistance and therapy failure due to drug-drug interactions are the main challenges in current treatment against Human Immunodeficiency Virus (HIV) infection. As such, there is a continuous need for the development of new and more potent anti-HIV drugs. Here we established a high-throughput screen based on the highly permissive TZM-bl cell line to identify novel HIV inhibitors....
OBJECTIVE To describe drug use, sexual risks and the prevalence of blood-borne viral infections among men who inject image and performance enhancing drugs (IPEDs). DESIGN A voluntary unlinked-anonymous cross-sectional biobehavioural survey. SETTING 19 needle and syringe programmes across England and Wales. PARTICIPANTS 395 men who had injected IPEDs. RESULTS Of the participants (median ...
BACKGROUND & OBJECTIVE AIDS and its associated gastrointestinal complications may impair the absorption of anti-tuberculosis (TB) drugs. Impaired absorption of anti-TB drugs could lead to low drug exposure, which might contribute to acquired drug resistance and reduced effectiveness of anti-TB treatment. The aim of this study was to obtain information on the status of absorption of rifampicin (...
OBJECTIVES Rates of TB/HIV coinfection and multi-drug resistant (MDR)-TB are increasing in Eastern Europe (EE). We aimed to study clinical characteristics, factors associated with MDR-TB and predicted activity of empiric anti-TB treatment at time of TB diagnosis among TB/HIV coinfected patients in EE, Western Europe (WE) and Latin America (LA). DESIGN AND METHODS Between January 1, 2011, and ...
HIV reverse transcriptase (RT) is one of the main targets for the action of anti-AIDS drugs. Many of these drugs [e.g., 3'-azido-3'-deoxythymidine (AZT) and 2',3'-dideoxyinosine (ddI)] are analogues of the nucleoside substrates used by the HIV RT. One of the main problems in anti-HIV therapy is the selection of a mutant virus with reduced drug sensitivity. Drug resistance in HIV is generated fo...
OBJECTIVES The use of multiple drug combinations in current anti-human immunodeficiency virus (HIV) therapy allows lower dosages of individual drugs and results in enhancement of the therapeutic effect due to synergic interactions between different drugs. We have shown that o-(acetoxyphenyl)hept-2-ynyl sulphide (APHS), a recently developed non-steroidal anti-inflammatory drug, shows anti-HIV ac...
Background: Although regular frequent blood transfusion improves overall survival of multi-transfused patients like β-thalassemic ones, it carries a definite risk of infection with blood-borne viruses such as viral hepatitis. This study was done to determine seropositivity of hepatitis B virus (HBV), hepatitis C virus (HCV), and Human Immunedeficiency Virus (HIV) infections among β-th...
New homo- and hetero-P(1),P(2)-dinucleotides were prepared with the use of multistep procedures starting from the monophosphates of 3'-fluoro-2-thiothymidine, 3'-fluoro-4-thiothymidine, AZT and 1-[(2-hydroxyethoxy)-methyl-5-propyl-6-phenylselenenyl]uracil. Anti-HIV properties of the synthesized P(1),P(2)-dinucleotides were evaluated against laboratory syncytia inducing strain HIV-1 in CEM-T4 ce...
Background Nephrotoxicity is a dose limiting side effect of Tenofovir (TDF), a commonly used anti-HIV drug. About 37-45% of patients on anti-HIV drugs suffer from renal damage. As the mechanism of pathogenesis of TDF induced renal damage is not clear, it is necessary to elucidate the mechanism in order to prevent the renal damage. This study investigates the roles of nitroso-oxidative stress an...
