background and aims: human t-lymphotropic virus (htlv) is a human retrovirus which has been known to cause adult t-cell leukemia/lymphoma and some other inflammatory disorders. patients with hereditary bleeding diseases are at high risk for these viruses. in this study, we evaluated serological htlv-i/ii infection among these patients in west azerbaijan of iran. material and methods: we studied...

background: as a drug target and an antigenic agent, hiv-1 protease (hiv-1 pr) is at the center of attention for designing anti-aids inhibitors and diagnostic tests. in previous studies, the production of the recombinant protease has been faced with several difficulties; therefore, the aims of this study were the easy production, purification of the soluble form of protease in e. coli and inves...

conclusions trim22 gene ring domain -364t/c polymorphism is associated with chronic hbv infection in chinese han population. results 243 (31.76%) of 765 chinese han patients showed genetic variation in the trim22 gene. trim22 snps were mainly in ring area -364t/c site, accounting for 98.35% of the population. there were no significant differences (p > 0.05) in the ring domain -364t/c snp and al...

background and aims: genotyping assay has been accepted as a guidance in the therapeutic management of human immunodeficiency virus 1 (hiv-1). but, it is not commonly used in our country due to its high running cost. the aim of this study is evaluate an in-house genotyping resistance test (grt) for hiv-1. methods: hiv-1 rna of 20 samples were extracted from plasma and rt nested- pcr was perform...

introduction: nowadays, hiv is mostly spreading in asian countries. one of the important routes for hiv transmission in these countries is the vertical route which infects 35% to 45% of newborns. mother’s education, drug prophylaxis and cesarean section, accompanied by banning breastfeeding will decrease this rate to 2%. therefore, mothers’ knowledge about prevention of mother to child transmis...

objective dot blot (db) assay provides highly specific results, but usually not reliable for quantification of antibody production. the need for a more objective db assay to provide a better definition of the immune status, against hiv antigens, promoted this study to be done to develop a quantitative db assay. material and methods dot blot (db) strips for antibodies directed to human immunodef...

Brown alga, Turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). The extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. Minimal inhibitory concentration was determined for active extracts by broth dilution method. The antiviral activity and cytotoxicity of the extracts were tested in human embryon...

amyotrophic lateral sclerosis is a progressive neurodegenerative disease with uncertain etiology. for many years, viruses have been suspected as causative agents. there are conflicting reports about the possible role of viruses such as human herpes virus 8 (hhv8) and retroviruses in the pathogenesis of the sporadic amyotrophic lateral sclerosis. we conducted a prospective case-control study to ...

Background & Aims: Various antiviral drugs such as amantadine are used to treat influenza. This drug is categorized in group C and few researches have been conducted about its toxic effects on human fetus. In the current study, the pathologic effects of the drug as well as drug efficacy in reducing influenza virus titer in the developing chicken embryo were assessed. <br ...
