the research problem investigated in this paper is modeling volatility and analyzing risk and return’s relationship in tehran stock exchange using garch-family models including garch(1,1), garch(2,2), egarch(1,1), pgarch(1,1), tgarch(1,1), garch(1,1)-m and cgarch(1,1). using the daily returns of tehran stock exchange companies, we focused on two portfolios of all the companies during a 10-year-...

Serine/threonine phosphorylation of insulin receptor substrate-1 (IRS-1) regulates the function and subsequent insulin signaling of this protein. Human IRS-1 has 1242 amino acid residues, including 182 serines and 60 threonines. The size, complexity, and relatively low abundance of this protein in biological samples make it difficult to map and quantify phosphorylation sites by conventional mea...

this research was conducted to evaluate the effects of 1-mcp and ethylene on extending the display quality and increasing vase life of cut carnation flowers in a completely randomized design with three replicationsat the laboratory of the postharvest physiology, tarbiat modares universityin 2014. first, cut flowers were treated with 0, 0.5, 1 and 1.5 µl l-1 of 1-mcp for 24 h and then exposed to...

Objective To assess whether MS genetic risk polymorphisms (single nucleotide polymorphism [SNP]) contribute to the enhanced humoral immune response against Epstein-Barr virus (EBV) infection in patients with MS. Methods Serum anti-EBV nuclear antigen 1 (EBNA-1) and early antigen D (EA-D) immunoglobulin γ (IgG) levels were quantitatively determined in 668 genotyped patients with MS and 147 hea...

One of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. The four pattern recognition molecules that have been identified till now are Mannose binding lectin (MBL), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. MBL ...

herpes simplex virus 1 (hsv-1) unspliced 8.3 latency associated transcript (lat), which located in the long repeat sequences, has been shown to contain at least 16 open reading frames (orf: a-p). one of these orf, orf p, maps almost entirely antisense to hsv-1 neurovirulence gene, icp34.5. both orf p and icp34.5 are located in the long repeat and are antisense overlapping genes. therefore, in o...

introduction: the present study aims to compare bile and urine samples of a corpse for detection of morphine. methods: in this cross-sectional study, forensic examination of the bodies placed 59 of the 366 referred corpses at the high suspicion of opioid overdose. urine and bile samples of the bodies were analyzed for morphine using thin layer chromatography. results: all samples were taken fro...
