the emergence of plasmodium vivax in dashte moghan in northwestern iran has become a major concern for iranian's health officials. knowledge of genetic make up of the p. vivax populations in this area would give us an insight into the origin of the prevalent infections and the possible routes they are introduced. this paper reports the analysis of a variable region between the two interspecies ...

background and objectives:  the molecular genetic of the human herpes virus 8 (hhv8) has now been characterized the pathogenesis of kaposi sarcoma (ks). this study attempted to determine the rate of hhu-8 infection in ks in an iraniann cross sectional study. method & material: in this cross-sectional study, we used paraffin-embedded specimens of 54 clinically well-characterized kaposi sarco...

background helicobacter pylori (h. pylori) infection is common among humans and plays a major role in the etiology of peptic ulcer disease with significant morbidity in patients with hiv-1 on antiretroviral therapy. there are conflicting prevalence patterns of h. pylori in hiv-1 infected patients using various methods of detection. the noninvasive technique used for detection of h. pylori infec...

objective: enterotoxigenic escherichia coli is considered as the most important agent of children diarrhea and mortality in developing countries. this bacterium causes 300-600 thousands of deaths in the children under 5 years of age per year. with difficulties in treatment as well as its wide prevalence, designing an effective vaccine against this microorganism is the objective of world health ...

Plasmodium vivax apical membrane antigen-1(PvAMA-1) is a surface protein with polymorphic sites. This study was aimed to analyze the polymorphic amino acid residues at PvAMA-1 in different infected age groups. 92 blood samples were collected from south and southeast of Iran. The DNA coding for the domain I (DI), DII, and partial DIII of this antigen was amplified by Nested-PCR, and sequenced. N...

Background: Cystic echinococcosis (CE), as a chronic parasitic disease, is a major health problem in many countries. The performance of the currently available serodiagnostic tests for the diagnosis of CE is unsatisfactory. Objective: The current study aimed at sub-cloning a gene, encoding the B8/1 subunit of antigen B (AgB) from Echinococcus granulosus, using gene optimization for the immunodi...

background: the wilm’s tumor gene 1 (wt1) encodes a zinc finger transcription factor that is inactivated in a subset of wilm’s tumors. it plays a crucial role in growth, proliferation and development of some embryonic and adult organs. wt1 is expressed as a tumor associated antigen (taa) in various types of solid and hematopoietic malignancies and can be employed as a useful marker for targeted...

the object of this cross sectional study was to determine the hcv subtype 3a envelope protein binding affinity with human leukocyte antigen. envelope 1 (e1) protein is one of the structural proteins responsible for entering the cells through the receptors. the binding affinity of e1 protein epitopes to the selected human leukocyte antigen (hla) class i alleles was investigated using the compute...
