Tuberculosis is the main cause for adults' death from a single infectious agent killing about 2 million people every year. Identifying the source of transmission infection is necessary to decrease tuberculosis. In this study we used IS6110-RFLP, MIRU-VNTR and ETR-VNTR methods to determine transmission dynamic of tuberculosis in Northwest of Iran from March(More)
AIM The aim of this study was to investigate anaerobic and aerobic bacteria profile and determination of antibiotic susceptibility pattern in aerobic bacteria. METHOD Specimens were cultured using optimal aerobic and anaerobic microbiological techniques. Identification of bacterial isolates was performed by standard microbiological methods and antibiotic(More)
Materials and methods: Among the 325 stool samples obtained from patients with acute gastroenteritis hospitalized in the Pediatric Hospital and infected humans referred to the Tabriz Reference Laboratory (TRL), 34 Giardia-positive stool samples were identifi ed by conventional techniques. Two assays–PCR and PCR-RFLP–targeting the tpi and gdh genes were(More)
The aim of present study was to determine the genotypes of isolates from East Azarbaijan province by this method. We performed (MIRU-VNTR) analysis of strains, isolated from 127 patients during a period of September 2002 to March 2003 in tuberculosis centers of the province. Among 127 isolates, we found 93 distinct MIRU-VNTR patterns, including in 21(More)
Visceral leishmaniasis is an infectious disease caused by various species of Leishmania and Leishmania infantum is known to be associated with VL in Iran. Different factors can consider risk factors for VL that some remain unknown. The aim of present study is to determine the distribution of the alleles ofmannose-binding lectin gene codon 52, 54, 57 and(More)
BACKGROUND Giardia lamblia is one of the most prevalent intestinal flagellate protozoa that infects a wide range of vertebrate hosts causing severe intestinal disorder in children.This study was performed to determine subspecies of G.lamblia by the PCR-RFLP method, targeting the glutamate dehydrogenase(gdh)locus, in hospitalized children at Urmia Mutahhari(More)
PURPOSE It is estimated that one third of the world's population were infected with M. tuberculosis, but only 10% of them have developed in to disease form. This subject refers to differences in host immune system activity against the tuberculosis. Vitamin D and its receptor (VDR) are important factors in the host innate immune system against the(More)
This article reviews recent advances achieved during recent years on various aspects of antibody humanization theories and techniques. Common methods for producing humanized antibodies including framework-homology-based humanization, germline humanization, complementary determining regions (CDR)-homology-based humanization and specificity determining(More)
The current review presents the results of the most recent studies performed on different aspects of human head and neck squamous cell carcinoma, including radiosensitivity induction, efficiency improvement of monoclonal antibodies using low-intensity ultrasound, chemical compounds such as toll-like receptor (TLC) agonists, dasatinib, resveratrol and(More)
Production of an efficient humanized single chain antibody is reported here to specifically target EGFRvIII, a truncated receptor expressed in a wide variety of human cancers. CDR loops of MR1, a phage display-derived murine single chain antibody developed against this mutant receptor, were grafted on human frameworks that had been selected based on(More)
