conclusions based on existing data, hiv infection surveillance, performance of standard precaution, and post exposure prophylaxis with anti-retroviral drugs outlined in this review article represent reasonable interim approaches to this complex problem. context human immunodeficiency virus (hiv) infection and acquired immunodeficiency syndrome (aids) concentrated in injecting drug users (idus) ...

In an attempt to identify potential new agents that are active against HIV-1, a series of novel pyridopyrimidine-5-carbohydrazide derivatives featuring a substituted benzylidene fragment were designed and synthesized based on the general pharmacophore of HIV-1 integrase inhibitors. The cytotoxicity profiles of these compounds showed no significant toxicity to human cells and they exhibited anti...

results the mean age of children was 6.5 ± 4.2 years. the frequency of positive results for hbsag, anti-hbs and anti-hcv in all age groups were 12 (3.6%), 47 (14.2%) and 2 (0.6%), respectively. anti-hiv was not detected in any of the children's serum samples. the frequency of positive results for hbsag was significantly higher in children older than six years than in other age groups. conclusio...

Background: GABAergic interneurons in the hippocampal CA1 area are mutually communicated by gap junctions (GJs) composed of connexin36 (Cx36). We examined the role of Cx36 in CA1 in manifestation of kindled seizures and hippocampal kindling in rats. Methods: Quinine, as the specific blocker of Cx36, was injected into CA1, and kindled seizures severity was examined 10 min afterward. Moreover, qu...

Phytochemical investigation of the aerial parts of Euphorbia erythradenia Bioss. (Euphorbiaceae), one of Iranian endemic Euphorbias, with particular attention to triterpene constituents, using methanol solvent extraction was carried out. Five known triterpenes, including four cycloartanes and oleanolic acid, were isolated for the first time and identified using NMR and Mass techniques. Anti HIV...

Several nonpeptide small molecules were designed as potential inhibitors of HIV protease and their structures were constructed by computer-aided molecular modeling and docked iwo the active site of HIV protease. Models of the complexes of inhibitors and the HIV protease were refined using nonbonded and H-bonding terms. The refined energy of selected complexes showed that the designed inhib...

objectives the aim of the present study was to estimate the prevalence of hiv infection in mashhad city. methods this cross sectional study was performed since may to september 2009 in mashhad, iran. a total of 1,678 individuals ranged 1-90 years of age were selected randomly from different geographical regions of the city, proportionate to sex and age distribution of the population according t...

patients and methods 720 cases including 120 patients undergoing hemodialysis, and 600 patients with hiv infection were studied. all cases with positive results for hbsag were evaluated for the presence of anti-hdv antibodies. samples with anti-hdv positive results were subjected to nested pcr for hdv-rna confirmation, and sequenced for hdv genotype determination. results hbsag was found in 9 (...
