ماکروفاژها از سلولهای مهم سیستم ایمنی در پاسخ به عوامل بیماریزای مختلف از جمله ویروس هرپس سیمپلکس یک 1- hsv0 هستند و عوامل موثر بر فعالیت آنها می توانند در سرنوشت بیماری موثر باشند. در این مطالعه اثر نوروپپتیدهای substance p(sp) وcalcitonin gene related-peptide (cgrp) که تحت شرایطی مثل استرس و التهاب از رشته های عصبی حسی آزاد می شوند و دارای گیرنده فعال بر روی ماکروفاژها می باشند ...
in view of the fundamental role of genetics in development of obesity, the present study aimed to investigate the single nucleotide polymorphism of some obesity-related genes among a subset of obese women living in tabriz, iran. for this purpose, 70 eligible obese women (aged 18-45 years) were genotyped for the uncoupling protein-1 (ucp-1) -3826a>g, ß3-adrenergic receptor (ß3adr) trp64arg, lept...
BACKGROUND Making the correct choice between transcription elongation and transcription termination is essential to the function of RNA polymerase II, and fundamental to gene expression. This choice can be influenced by factors modifying the transcription complex, factors modifying chromatin, or signals mediated by the template or transcript. To aid in the study of transcription elongation and ...
The best approximation problem in a hyperconvex metric space consists of finding conditions for given set-valued mappings F andG and a setX such that there is a point x0 ∈ X satisfying d G x0 , F x0 ≤ d x, F x0 for x ∈ X. When G I, the identity mapping, and when the set X is compact, best approximation theorems for mappings in hyperconvex metric spaces are given for the single-valued case in 1–...
Given a directed graph with n nodes, a root r, a setX of k nodes called terminals and non-negative weights ω over the arcs, the Directed Steiner Tree problem (DST) asks for a directed tree T ∗ of minimum cost ω(T ∗) rooted at r and spanning X. If this problem has several applications in multicast routing in packet switching networks, the modeling is no longer adapted in networks based upon the ...
Objectives. The validity of administrative osteoarthritis (OA) diagnosis in British Columbia, Canada, was examined against X-rays, magnetic resonance imaging (MRI), self-report, and the American College of Rheumatology criteria. Methods. During 2002-2005, 171 randomly selected subjects with knee pain aged 40-79 years underwent clinical assessment for OA in the knee, hip, and hands. Their admini...
many factors including genetic, environmental, and acquired are involved in breast cancer development across various societies. among all of these factors in families with a history of breast cancer throughout several generations, genetics, like predisposing genes to develop this disease, should be considered more. early detection of mutation carriers in these genes, in turn, can play an import...
Let N0 be the set of all non-negative integers, let X N0 and P(X) be the the power set of X. An integer additive set-labeling (IASL) of a graph G is an injective function f : V (G) ! P(N0) such that the induced function f+ : E(G) ! P(N0) is defined by f+(uv) = f(u) + f(v), where f(u) + f(v) is the sum set of f(u) and f(v). An IASL f is said to be an integer additive set-indexer (IASI) of a grap...
This paper characterizes when a Delone setX in Rn is an ideal crystal in terms of restrictions on the number of its local patches of a given size or on the hetereogeneity of their distribution. For a Delone set X, let NX(T ) count the number of translation-inequivalent patches of radius T in X and let MX(T ) be the minimum radius such that every closed ball of radius MX(T ) contains the center ...
ریحان(ocimum basilicum l.) از گیاهان دارویی تیره نعناع و سرشار از ترکیبات فنیل پروپانوئیدی است. در این تحقیق به منظور مطالعه تأثیر متیل جاسمونات بر بیان ژن های چاویکول-o-متیل ترنسفراز(cvomt) و سینامات چهار هیدروکسیلاز (c4h) (ژن های کلیدی دخیل در بیوسنتز فنیل پروپانوئیدها) و آنزیم های آنتی اکسیدانت آسکوربات پراکسیداز و گایاکول پراکسیداز در گیاه ریحان رقم کشکنی لولو، آزمایشی بر پایه طرح کاملاً تصا...
