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...

Abstract : Avian influenza virus (AIV) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. Although the risk of infection with avian influenza virus (AIV) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the ra...

background blastocystis is a common protozoan parasite in mammals, birds, amphibians,reptiles, fish, arthropods, and annelids. this parasite has some subtypes, which pathogenicity status of them still remained controversial. some of blastocystis subtypes are potentially pathogenic to human. objectives this study has identified the b. hominis subtypes and their prevalence rates in hamadan. patie...

Background: Basal cell carcinoma (BCC) is the most common skin cancer in whites. Objective: Determination of anatomical localization of BCC in relation to histological subtypes of this tumor. Patients and methods: This survey is a descriptive cross sectional study carried out on 189 cases of BCC patients diagnosed in Hamadan Sina hospital between 1997-1999. Results: This study showed 7 hi...

Background: HLA-B*27 is strongly associated with ankylosing spondylitis (AS). It represents a family of alleles that differ among ethnic groups. Objective: The aim of this study was to determine the distribution of HLA-B*27 alleles in AS patients and healthy controls in Isfahan (Iran). Methods: Sixty AS patients and 430 healthy blood donors were selected. All subjects were HLA-B*27 positive by ...

Avian influenza virus (AIV) infection is a major cause of bird or human mortality and morbidity, therefore the rapid identification of the virus is of important clinical and epidemiological implication. Methods: A multiplex Reverse Transcriptase PCR (RT-PCR) was optimized for the detection of influenza A virus and the H5 and H9 subtypes. The influenza type A specific primers were directed to t...

Background: Basal cell carcinomas (BCC) are the most prevalent among non-melanoma skin cancers (NMSC), which correspond to the most common skin cancers. BCC histopathological subtyping is a problem in therapeutic management. Therefore, we have decided to perform a histopathologic study for better classification of BCCs based on interobserver diagnostic judgment. Methods: We conducted this cross...
