Aerobic exercise has been shown to counteract age-related neurological decrements that are associated with cognitive and physical impairments. However, the effects of resistance exercise on cognition, reaction, and neurotrophins are largely unknown. We examined changes in spatial awareness, visual and motor reaction, and circulating brain-derived neurotrophic factor (BDNF) in response to a resi...
بررسی الگوی مقاومت آنتی‌بیوتیکی در ایزوله‌های استافیلوکوکوس کواگولاز منفی جداشده از نمونه‌های بالینی
Background and Objective: Due to the emergence and development of antimicrobial resistance in coagulase-negative Staphylococci (CoNS), which is mainly a normal flora of the skin surface and mucous membrane of humans, and the limitation of therapeutic options, this study was aimed to investigate the antibiotic resistance pattern in CoNS strains isolated from clinical specimens. Materials and Me...
background: downy mildew caused by plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. so far several dominant resistance genes designated as pl have been identified and their molecular markers linked to these genes are available. however, no information on the resistance genes is available in iranian lines. objective: in this study, the presence of three map-ba...
چکیده : * در یک واکنش تک ظرفی و با استفاده از واکنش آلدهید های آروماتیک و 3- متیل 1- فنیل پیرازولین-5- ان با نسبت مولی 1:1، ساختارهای هتروسیکل پیرازول سنتز شد. از مزایای آن، انجام واکنش در دمای اتاق، عدم نیاز به کاتالیزور، بازده بالای واکنش، استفاده از آب بعنوان حلال سبز و بی خطر به جای حلال های آلی وسمی می باشد . * توانستیم با استفاده از ملدرام اسید ومشتقات 2- هیدروکسی بنزآلدهید، ترکی...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
سوختگی باکتریایی از بیماریهای بسیار مهم و مخرب پنبه در سراسر جهان است. باکتری عامل بیماری xanthomonas citri.pv.malvacearum از طریق بذور آلوده منتقل میشود. در حال حاضر برای ردیابی این باکتری از روشهای سنتی همچون آزمونهای بیوشیمیایی وسرولوژیکی استفاده میشود که وقت گیر و غیر قابل اعتماد هستند. در این تحقیق برای اولین بار طراحی روشی مبتنی بر polymerase chain reaction (pcr) جهت ردیابی این باکتری مور...
Staphylococcus aureus is colonized in the human nasal cavity and would contaminate hospital and therapeutic environments. This bacterium has a genetic diversity in terms of resistance to antimicrobial agents. Therefore, the purpose of this study was identificatied of Methicillin and Vancomycin resistant genes in Staphylococcus aureus strains which has been isolated from the nasal cavity. 189 pa...
Objective(s) Resistance to antimicrobial agents, particularly metronidazole and clarithromycin, is frequently observed in Helicobacter pylori and may be associated with treatment failure. This resistance rate varies according to the population studied. The aim of this study was to assess the pattern of antimicrobial resistance of H. pylori isolates from dyspeptic patients in Isfahan. Material...
OBJECTIVE To evaluate multiplex allele specific polymerase chain reaction as a rapid molecular tool for detecting multidrug-resistant tuberculosis. METHODS Based on drug susceptibility testing, 103 isolates were multidrug-resistant tuberculosis and 45 isolates were sensitive to isonicotinylhydrazine and rifampin. Primers were designed to target five mutations hotspots that confer resistance t...
