Background: Enzymatic hydrolysis of lactose is one of the most important biotechnological processes in the food industry, which is accomplished by enzyme β-galactosidase (β-gal, β-D-galactoside galactohydrolase, EC 3.2.1.23), trivial called lactase. Orthogonal arrays design is an appropriate option for the optimization of biotechnological processes for the production of microbial...
Background and Objective: Pseudomonas aeruginosa is a causative agent of nosocomial infections. Metallo-beta-lactamases (MBLs) are considered among the most crucial resistant agents of Pseudomonas aeruginosa to carbapenem. Because of the important role of carbapenemes in the treatment of Pseudomonas infections, in this study, the Pseudomonas aeruginosa producing metallo-beta-lactamases were inv...
Background & Objective: Angiopoietin-like Proteins 8 (ANGPTL8) which secreted form adipose tissue due to downstream PGC-1α pathways, is the main factor for regeneration of beta cell. The aim of this study was to investigate the effect of 4 endurance training program on PGC-1α expression in adipose tissue, ANGPTL8 serum concentration and beta cell function (HOMA.B) in diabetic rats. Materials & ...
Background: Glycogen synthase kinase 3 beta is a key regulator of many signaling pathways. It is reported that Inhibition of this kinase results neuronal survival. Accordingly in this study we investigated the effect of endurance training on the gene expression of GSK-3β in the sensory areas of the spinal cord of male Wistar rats with diabetic neuropathy. Methods: we randomly assigned 1...
چکیده این پژوهش با هدف بررسی رابطه ی راهبردهای تنظیم انگیزش با خودکارآمدی و رضایت از تحصیل دانش آموزان دبیرستانهای دولتی شیراز انجام شد. در این پژوهش 403 دانش آموز (182دختر و 221پسر) از دوناحیه از نواحی چهارگانه شیراز به صورت خوشه ای چند مرحله ای گزینش شدند و پرسشنامه های راهبردهای تنظیم انگیزش، خودکارآمدی و رضایت از تحصیل را تکمیل نمودند. با استفاده از spss و روش های آماری تعیین ضریب همبستگ...
هدف پژوهش بررسی میزان تأثیر سرمایه فکری بر کسب مزیت رقابتی بانک پارسیان در صنعت بانکداری بود. این پژوهش بر اساس یافته های تحقیق میدانی در شعب بانک پارسیان تهران شکل گرفته است. جامعه آماری پژوهش شامل کلیه مدیران و کارکنان شعب بانک پارسیان تهران(تعداد پرسنل :5000 نفر) بود. که با استفاده از روش نمونه گیری تصادفی خوشه ای، و بر اساس فرمول نمونه گیری کوکران تعداد 367 نفر از کارکنان به عنوان نمونه انت...
Background and purpose: New biochemical markers(Fibronection, esteriol, à- feto protein,…) to predict spontaneous preterm birth give a more precise and earlier diagnosis than the usual ones( previous history, risk scoring system,…) there are many women with no obvois risk factors who deliver prematurely. The main purpose of this study was to determine the relationship between preterm delivery...
Background: The thyroid gland absorbs nearly all the iodine in the blood, independently of its isotopic composition. When a large enough activity of radioactive iodine like 131I, 132I, 133I is taken into the body, it can destroy the healthy thyroid gland cells as well as the cancer’s cells. In fact, as it is well known, some isotopes of iodine are used not only for acquiring thyroid image...
In the future neutrino experiments, a beta-beam, which can produce pure electron neutrino beam, is expected to achive precise measurement of the neutrino oscillation parameters. In the νμ appearance measurement of a beta-beam, a detector does not need to identify particle charge and thus, a water Cherecov detector will be a candidate for the far detector. In this paper, we study the expected si...
