Bayesian model and Markov chain Monte Carlo method were used to verify a sample of signature in Iran. In the Bayesian model, parameters were considered as quantities whose variations can be described by the prior distributions. A sample is taken from a population indexed by the parameters and prior distributions were updated and then posterior distribution was calculated. Markov chain Monte Car...

BACKGROUND The aim of this study was to determine the cumulative prevalence rate of every sexual dysfunctions (SDs) in Iranian population. METHODS We searched international database such as: PubMed/Medline, Scopus, PsychNET, and Scholar Google and Iranian database such as Iran Psych, IranDoc, IranMedex, and SID. Search duration was between 1990 and 2013. RESULTS From 449 articles were retri...

The protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene, which encodes an intracellular lymphoid-specific phosphatase, is considered an important regulator of T-cell activation. We investigated a possible association between the PTPN22 C1858T (R620W) polymorphism and pulmonary tuberculosis in an Iranian population. Single nucleotide polymorphisms of PTPN22 C1858T (rs2476601) we...
