POU domain transcription factors are required for neuropeptide expression in selected subsets of hypothalamic neuroendocrine neurons. We now report that expression of the gonadotropin-releasing hormone (GnRH) gene, which controls sexual development, is regulated by the POU protein SCIP/Oct-6/Tst-1. Reverse transcriptase PCR cloning and RNase protection assays demonstrated the presence of SCIP/O...
Approximately 20% of persons living in areas hyperendemic for tuberculosis (TB) display persistent lack of tuberculin skin test (TST) reactivity and appear to be naturally resistant to infection by Mycobacterium tuberculosis. Among those with a positive response, the intensity of TST reactivity varies greatly. The genetic basis of TST reactivity is not known. We report on a genome-wide linkage ...
AIM Absolute and relative quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR) by the use of two mathematical models were applied in order to study the expression of tst gene encoding the toxic shock syndrome toxin-1 (TSST-1), among methicillin-resistant Staphylococcus aureus (MRSA). METHODS AND RESULTS Thirteen epidemic MRSA belonging to different clones and carryi...
staphylococcus aureus is a major causative pathogen of clinical and subclinical mastitis of dairy domestic ruminants. this agent produces a variety of extracellular toxins and virulence factors including toxic shock syndrome toxin-1 (tsst-1) which is the major cause of toxic shock syndrome (tss). in this study 58 s. aureus isolates obtained from 9 dairy herds in east and west azerbaijan prov...
The tuberculin skin test (TST) is a model of integrated innate and adaptive human immune responses to Mycobacterium tuberculosis, but the component processes that are involved in this model have not previously been defined in vivo. We used transcriptional profiling to study these responses within the TST at molecular and system levels. Skin biopsies from TST injection sites were examined in sub...
The peptide hormone somatostatin inhibits the release of insulin. The gene encoding somatostatin receptor 1 is expressed in pancreatic beta-cells and insulinoma RIN 1046-38 cells. In the present study the mechanisms underlying the regulation of the somatostatin receptor 1 gene in pancreatic beta-cells were investigated. Transient transfections of RIN 1046-38 cells with promoter/reporter gene co...

the frequency of staphylococcus aureus isolated from endocervix of infertile women in northwest iran
objective: infertility is one of the major important social issues. because of the asymptomatic cervical infection, it has caused the problem to remain silent in the majority of patients without diagnosis and treatment. the present study was intended to assess the frequency of staphylococcus aureus isolated from infertile women's endocervix in northwest iran. materials and methods: in a descrip...
