[ 1 ] - تأثیر تمرین هوازی در هوای آلوده به ذرات کربن سیاه بر بیان ژن‌های TLR4 و IL-1β در بافت قلب موشهای صحرایی نر
پژوهش حاضر اثرات تمرین هوازی بر فاکتورهای التهابی قلب موشهای درمعرض ذرات کربن سیاه را موردبررسی قرار داده است. در این پژوهش، 24 سر موش نر بالغ نژاد ویستار 10 هفتهای با میانگین وزنی 97/26±29/279 گرم به چهار گروه ششتایی تقسیم شدند که عبارت هستند از: گروه کنترل (بدون تمرین هوازی و قرارگیری درمعرض PM10)، گروه تمرین هوازی (پنج جلسه در هفته و بهمدت چهار هفته)، گروه قرارگیری درمعرض PM10 کربن ...
[ 2 ] - Wrestlers’ immune cells produce higher interleukin-6 and lower interleukin-12 and interleukin-13 in response toin vitro mitogen activation
Objective(s):Although recent investigations have shown chronic inflammation and inflammation-associated diseases might be ameliorated by exercise; little is known about the relation between exercise training with anti/pro-inflammatory cytokines. Materials and Methods: This cross sectional study was conducted to compare interleukin-4 (IL-4), IL-6, IL-10, IL-12, IL-13, interferon gamma (IFN-γ) le...
[ 3 ] - Detection of magA Gene in Klebsiella spp. Isolated from Clinical Samples
Objective(s): Klebsiella infections are caused mainly by K. pneumoniae and K. oxytoca. In the last two decades, a new type of invasive Klebsiella pneumoniae which contains mucoviscosity-associated gene (magA) has emerged. The aim of this study was to investigate the prevalence of magA gene and to detect antimicrobial susceptibility patterns of Klebsiella spp. isolated from clinical samples....
[ 4 ] - Effect of Cinnamon and Turmeric Aqueous Extracts on Serum Interleukin-17F Level of High Fructose-Fed Rats
Background: Studies have indicated that extraweight and obesity induce chronic inflammation, which can lead to other diseases such as cancers. Objective: To evaluate the effects of two weight-lowering and anti-inflammatory agents including cinnamon, and turmeric, on serum levels of interleukin-17 (IL-17) as a pro-inflammatory cytokine. Methods: In this study, 64 rats were designated in eight...
[ 5 ] - Molecular Cloning and Expression of Human Gamma Interferon (IFN-g) Full cDNA in Chinese Hamster Ovary (CHO) Cells
Background: IFN-g is mostly secreted by activated CD4+ , CD8+ T cells and NK cells. This cytokine has immunomodulatory, anti-cancer and anti-microbial effects and is important for prophylaxis, diagnosis and treatment of chronic infections and cancers. Objective: The purpose of this study was to clone the full cDNA of human IFN-g and express it in CHO cell line. Methods: Lymphocytes from a healt...
[ 6 ] - بررسی فراوانی ژن مقاومت به متی سیلین (mec-A) در سویه های مختلف استافیلوکوک اورئوس با PCR و تعیین حساسیت آنتی بیوتیکی آن
Background & Objective: Methicillin–Resistant Staphylococcus aureus (MRSA) is one of the most important causes of hospital infections worldwide. Treatment of these infections has become more difficult because of resistance to methicillin/oxacillin and other antibiotics. The aim of this study was to determine the incidence of MRSA infections in hospitals affiliated to Hamadan University of Med...
[ 7 ] - تأثیر تمرین استقامتی و مصرف متادون بر سطح سرمی اینترفرون گاما و اینترلوکین 17 در موش های صحرایی وابسته به مورفین در دوره سندروم ترک
هدف: هدف از پژوش حاضر بررسی تاثیر8 هفته تمرین استقامتی و مصرف متادون به عنوان جایگزین مورفین بر سطح سرمی سایتوکاین های اینترفرون گاما و اینترلوکین17 بود. مواد و روش ها: تعداد24 موش صحرایی نر نژاد ویستار با وزن 10±220گرم به چهار گروه کنترل، ورزیده، مصرف کننده متادون، ورزیده مصرف کننده متادون تقسیم شدند. همه گروه ها به وسیله مورفین سولفات mg/mL4/0 در طی21روز معتاد شدند. برای اطمینان از وابستگی ...
[ 8 ] - Designing E1 Deleted Adenoviral Vector by Homologous Recombination
Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...
[ 9 ] - Inducible Expression of Human Gamma Interferon
Background:The premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. Furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. So, it is necessary to tightly control IFN-γ pr...
