مقدمه: ناباروری یک نشانگان چند عاملی با عوامل ژنتیک و غیرژنتیک متفاوت است. به رغم پیشرفت های روش شناختی، علت متجاوز از 25 درصد ناباروری ها ناشناخته است(ناباروری ایدیوپاتیک). در 50 درصد موارد عامل مرد به نوعی در ناباروری دخیل است. kiss1 ژنی است که بر بازوی بلند کروموزوم شماره یک قرار دارد. نقش مهم این ژن در کنترل متاستاز شناخته شده ولی از سال 2003 به اهمیت آن در بلوغ، تخمک گذاری و باروری پی بردن...
As undergraduate research experience programs proliferate to include all students, the need to evaluate and assess these types of programs also grows. This paper presents an overview of the evaluation/assessment process and a framework for developing an evaluation plan to assess the effectiveness and impact of the undergraduate research experience. Drawing on the ongoing evaluation of the Affin...
Introduction: Renal ischemia reperfusion (I/R) caused kidney injury gender dependently. High fat diet (HFD) contributes the development of renal dysfunction. L-arginine (L-arg) and regular exercise are recognized to be protective in I/R and lipotoxicity. We compared the role of aerobic exercise and L-arg supplementation against renal I/R in male and female rats fed with HFD. Methods: 54 adult ...
چکیده ژن p53 به عنوان سرکوب کننده تومور، نقش مهمی در پایداری ژنومیک دارد. پلی مورفیسم g-to-c در کدون 72 از ژن p53 با افزایش خطر ابتلا به سرطان های ریه، نازوفارنکس، دهان، پروستات و کولورکتال ارتباط دارد و شاید بتوان آن را به عنوان مارکر استعداد ابتلا به سرطان پستان در نظر گرفت. این پژوهش، تأثیر این پلی مورفیسم ژن p53 بر کارسینومای مجرایی مهاجم پستان را بررسی نمود. روش ها: این مطالعه مورد-شاهدی ب...
this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...
The low fiber digestibility and unbalanced amino acids restricted the use of DDGS in swine diets. Key nutrition components dynamic monitoring key regulatory pathways analysis were performed to find rules changes for fermented by Aspergillus niger. Cellulose hemicellulose reduced 15.3% 15.2%. 1,4-D-Xylobiose was decreased from 16.8 ?g/mL 0.2 ?g/mL. Lys, Arg, Thr increased 3.00%, 2.89%, 4.40%, me...
backgrounds and aims: p53 gene is regarded important in pathogenesis of different cancers. therefore, this study aimed to investigate the frequency of p53 gene codon 72 arg/pro polymorphism in women suffering from breast cancer. materials and methods: a total of 90 patients with breast cancer and 83 matched healthy control women participated in this case-control study. genomic dna was extracted...
glycine allele at codon 16 has previously been associated with the increase in asthma severity, bronchial hyperresponsiveness and also the increase in inhaled corticosteroid dependence. this study was designed to evaluate the genetic alleles in mild asthma.thirty-four patients with diagnosis of mild asthma (fev1 ≥ 80%, positive methacholine test) and body mass index (bmi ≤ 30 kg/m2) were includ...
Ontology alignments enable agents to communicate while preserving heterogeneity in their knowledge. Alignments may not be provided as input and should able evolve when communication fails or new information contradicting the alignment is acquired. The Alignment Repair Game (ARG) has been proposed for simultaneously repair through adaptation operators failures occur. ARG evaluated experimentally...
The objective of this study was to evaluate the effects arginine (ARG) and/or lysine (LYS) supplementation on meat quality and oxidative stability beef loins. Steers (n = 40) were split among four dietary treatments (control, ARG, LYS or ARGLYS). loins (longissimus lumborum) obtained at 1 day postmortem aged either 14 28 days prior cutting steaks for 7 display. No impacts diet instrumental tend...
