human immunodeficiency virus infection / acquired immunodeficiency syndrome (hiv/aids) is a disease pertained to the human immune system. given its crucial role in viral replication, hiv-1 protease (hiv-1 pr) is a prime therapeutic target in aids therapy. in this regard, the dynamic aspects of ligand-enzyme interactions may indicate an important role of conformational variability in hiv-1 pr in...

Human anti-human leukocyte antigen (HLA) antibodies were assessed for neutralizing activity against human immunodeficiency virus type 1 (HIV-1) carrying HLA alleles with matching specificity. Multiparous women carrying anti-HLA antibodies were identified. Plasma samples from those women were confirmed as having antibodies that specifically bound to HLA proteins expressed on the peripheral blood...

Infections caused by hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency viruses (HIV) remain the leading most important health problems worldwide. Screening tests such as HBsAg, anti-HCV, anti-HIV and VDRL are mandatory tests to look at before transfusion of blood or blood components. In this study, donors who applied to our Blood Center in a nine-year period were retr...

Background: HIV infected persons are also at risk for Infection with other pathogens, like Hepatitis B virus (HBV) and Hepatitis C virus (HCV). One of the main steps in the planning of treatment and prevention is the study of the HIV positive population who have HBV and/or HCV infection. The objective of this study was to determine the prevalence of HIV and Hepatitis B and C dual infection in ...

Infection with human immunodeficiency virus remains a global concern with a significant number of incident infections still reported worldwide. The use of prophylaxis prior to exposure to the virus to prevent infection has been a growing area of recent research. Results in nonhuman primates and clinical trials in high-risk patient populations using preexposure prophylaxis have shown promising r...

Aim
 Substance abuse and concomitant infections are important causes of morbidity mortality. Yet, the number epidemiological studies regarding infectious diseases in people with substance limited our country. In this study, aim was to investigate frequency illegal alcohol use an Alcohol Drug Research, Treatment Training Centres (AMATEM) clinic Turkey as well HBsAg, anti-HBs, anti-HCV, anti...

HIV/AIDS pandemics is a serious threat to health and development of mankind, and searching for effective anti-HIV agents remains actual. Considerable progress has been made in recent years in the field of drug development against HIV. A lot of structurally different coumarins were found to display potent anti-HIV activity. The current review demonstrates the variety of synthetic coumarins havin...

B cell activation is a well known consequence of HIV-1 infection, and seropositive subjects show high numbers of spontaneously activated Ig-secreting cells in circulation. To better define the importance of the HIV-1-specific response in this phenomenon, we first studied whether in vitro spontaneous anti-HIV-1 antibody production was accompanied by reactivation of memory B lymphocytes. Unstimul...

This study evaluated the usefulness of the anti-HBc, hepatitis C virus antibodies (anti-HCV), human T cell lymphotropic virus I and II antibodies (anti-HTLV I/II), serologic tests for syphilis, and surface antigen of hepatitis B virus (HBsAg) as surrogate markers for the risk for HIV infection in 80,284 serum samples from blood donors from the Blood Bank of "Hospital Universitário Regional Nort...

In our search for novel anti-human immunodeficiency virus (HIV)-1 agents, 14 delavirdine analogues were synthesized and evaluated as potential anti-HIV-1 agents in cell-based assays. Compound 1Aa exhibited potent and selective anti-HIV-1 activity in acutely infected MT4 cells, with effective concentration (EC50) values in the submicromolar range.
