Objective(s): HTLV-I and HIV virus quantification is an important marker for assessment of virus activities. Since there is a direct relationship between the number of virus and disease progression, HTLV- I and HIV co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated.   Materials and...

Background: Intestinal protozoa transmitted by food are the most common opportunistic parasites among the HIV+/AIDS patients. As, there is no report about prevalence of food-borne intestinal parasites in such patients in Yazd, so this study was performed to determine the prevalence of intestinal protozoa in the HIV+/AIDS patients in comparison with HIV- individuals. Methods: A case-control stu...

we conducted this study to obtain a comprehensive picture of molecular epidemiology of hiv-1 in three neighboring countries, i.e. afghanistan, iran, and pakistan as a basis for discussing possible hypothesis regarding between-country virus transmission. our results showed that subtype composition differs between these countries with more variation in pakistan than iran and afghanistan. the crf3...

Lentiviral vectors are promising gene delivery tools capable of transducing a variety of dividing and non-dividing cells, including pluripotent stem cells which are refractory for transduction by murine retroviruses. Although there is a growing debate on the safety of lentiviral vectors for gene transfer, in particular for those derived from human immunodeficiency viruses, type one (HIV-1) and ...

Human immunodeficiency virus type 1 (HIV-1) and human T-lymphotropic I (HTLV-I) are two retroviruses that have a similar fashion of transmission via sharp objects contaminated by viruses, transplant surgery, transfusion, sexual relations. Simultaneous infections with HTLV-I HIV-1 usually occur in areas where both viruses become endemic. CD4+T cells the main targets HTLV-I, while can infect macr...

Infection with human immunodeficiency virus type 1 (HIV-1) or T-lymphotropic I (HTLV-I) both can lead to mortality. CD4+T cells are the target for HTLV-I and HIV-1. In addition, HIV-1 infect macrophages. macrophages play important roles in immune system response. This article develops analyzes a discrete-time co-infection model. The model depicts within-host interaction of six compartments: uni...

Background: Thalassemia syndromes are the most common genetic disorders in the world. They happen due to genetic defects in process of haemoglobin synthesis, and would be classified to many groups mainly α and β, based on the kind of defect. Anemia is the main clinical manifestation of this phenotype of disorder. In order to correct the chronic anemia in thalassaemic individuals, they may need ...
