b a ckground: great gerbils, rhombomys opimus , are the main reservoir host of zoonootic cutaneous leishmaniasis (zcl) in iran and neighboring countries. based on morphological traits two subspecies r. opimus sodalis and r. opimus sargadensis have reported in the country. however, variation in infection rate and signs to leishmania parasites, phenotype, size, and sexual polymorphisms demand mor...

A principal difference between malignant and normal cells is the aberrant expression of oncogenes. Previously, we have reported on the expression of the insulin-like growth factor 1 receptor (IGF-1-R) in 93% of the human primary breast cancers studied. In the present study, we observed an increased gene copy number of the IGF-1-R in only 19 (2%) of 975 cases studied. The gene copy number of tum...

Background: The frequency of pyruvate kinase (PK) deficiency, an autosomal recessive defect, is approximately 3 per 10,000 individuals in Shiraz and surrounding areas, and is increased due to high consanguinity marriage frequency. The purpose of this study is to obtain data on the frequency and spectrum of gene mutation of PK in newborns, from Shiraz and surrounding areas. Materials and Methods...

This study aimed to investigate the expression of tumour necrosis factor receptor (TNF-R) at the gene and surface level, and its shedding in human lung tissue and a pulmonary epithelial cell line, A549. Levels of gene expression of TNF-R were evaluated by Northern blot analysis. Human lung tissue expressed both type I and type II TNF-R gene, while A549 cells expressed only type I TNF-R gene. Ph...
