Effects of induced mutation via gamma irradiated with 250 Gy dose (in Nuclear Agriculture Research School- Nuclear Science and Technology Research Institute) on Trichoderma harzianum conidiaon chitinase activity by STS molecular marker have been evaluated in this study. Among 20 irradiated mutants which selected via improved antagonistic capability against Rhizoctonia sola...

UNLABELLED MET inhibition is effective in some patients with MET-amplified esophagogastric cancer (EGC), but understanding acquired and de novo resistance mechanisms will be critical to improving therapy. We identified KRAS mutation as a novel cause of acquired resistance in a patient after a 2-year response to a MET inhibitor. We also observed that 40% to 50% of patients with MET-amplified EGC...

Background and objectives: Behcet's Disease (BD) is a rare severe recurrent inflammatory disorder affecting several body organs. Since Familial Mediterranean Fever (FMF) and BD affect almost a specific population, both diseases can mimic the other clinically, and these two diseases sometimes occur in the same family and the same patient, also due to the high prevalence of BD in Iran and perform...

AIMS To detect HLA susceptibility and protective alleles associated with insulin dependent diabetes mellitus (IDDM) using a multiplex amplification refractory mutation system (ARMS). These include DR3 and DR4 alleles at the DRB1 locus, presence or absence of aspartic acid at position 57 (Asp-57) of the DQB1 locus, and presence or absence of arginine at position 52 (Arg-52) of the DQA1 locus. ...

Background: The pathogenesis of migraine involves immune-mediated mechanisms in the vascular endothelium. Toll like receptor 4 (TLR-4) is a signaling receptor of innate immunity which plays a role in various neuropathologies related to neuron inflammation. Objective: This case/control study is aimed to investigate whether TLR- 4 896A/G variation is related to migraine headaches in an Iranian po...

background: mutations in β -globin gene may result in β-thalassemia major, which is one of the most common genetic dis­or­ders in iran and some other countries. knowing the beta-globin mutation spectrum improves the efficiency of prenatal diagno­sis in the affected fetuses (major β-thalassemia) of heterozygote couples. methods: couples with high hemoglobin a 2 and low mean corpuscular volume we...

Single-nucleotide polymorphisms (SNPs) in miRNAsmay alter its expression levels or processing and contribute to susceptibility to a wide range of diseases. Our study aimed to evaluate the possible association between miRNA-146a rs2910164 and miRNA-499 rs3746444 polymorphisms and susceptibility to pulmonary tuberculosis (PTB) in a sample of Iranian population. This case- control study was perfor...

Schizophrenia is a severe neuropsychiatric disorder with symptoms such as hallucination, delusion and mental disorder. It is a complex disorder, in which genetic components play a crucial role in its pathogenesis. Among candidate genes for schizophrenia, Neuregulin 1 (NRG1) gene is the most important gene,  association of which with the illness has been confirmed in several studies. Single nucl...

Background & Aims:Thromboembolism is an acute cardiovascular disease that ranges from clinically unimportant to massive embolism. Both acquired and hereditary risk factors contribute to the disease.
We aimed to determine the prevalence of two hereditary predisposing factor of the disease, prothrombin G20210A and factor V Leiden (G1691A) polymorphisms, in Kerman population.<br /...
