[ 1 ] - تأثیر 12 هفته تمرین ورزشی شنا زیربیشینه بر سطوح استراحتی VEGF رت‌های در معرض نیتروز آمین کتون مشتق از تنباکو
زمینه و هدف: دخانیات حاوی مواد سرطان‌زا، ازجمله NNK با تحریک بیان VEGF در القای سرطان ریه نقش دارند. هدف مطالعه حاضر بررسی تغییرات سطوح استراحتی VEGF بافت ریه رت‌های در معرض نیتروز آمین کتون مشتق از تنباکو در پی 12 هفته تمرین هوازی شنای زیربیشینه بود. روش بررسی: در این مطالعه تجربی، 46 سر موش صحرایی بالغ نژاد ویستار به‌صورت تصادفی به پنج گروه شامل: گروه تمرین، تمرین+NNK، NNK، حلال و کنترل تقسی...
[ 2 ] - مطالعه تأثیر یک دوره مصرف نانوکپسول سیاه دانه بر ساختار هیستوپاتولوژیک و سطوح فاکتور رشد اندوتلیال عروق بافت ریه موش‌های صحرایی در معرض نیتروز آمین کتون مشتق از تنباکو
Background and Objectives: Cigarette smoke contains carcinogenic compounds, including nicotine-derived nitrosamine ketone (NNK), which can activate vascular endothelial growth factor (VEGF) and increase the inflammation of the lung. Since the Nigella sativa plays an important role in treating cancer through the modification of cellular signaling pathways, the purpose of this study was dete...
[ 3 ] - Effect of a 12-week submaximal swimming training in rats exposed to tobacco- derived nitrosamine ketone
Background: Tobacco contains carcinogens such as NNK (nicotine-derived nitrosamine ketone) that makes induction of lung cancer by changing the stimulation of IL-10 expression. The aim of this study was to investigate changes in resting levels of IL-10 in lung tissues of rats exposed to NNK after a 12-week aerobic submaximal swimming training. Methods: For this purpose, 46 Wistar rats were rand...
[ 4 ] - Effect of one Bout Continuous Versus Intermittent Aerobic Exercise on Plasma Levels of Intercellular Adhesion Molecules 1 and Vascular Cell Adhesion Molecules 1 in Patients with Coronary Heart Disease
Introduction: Adhesion molecules play an important role in the pathogenesis of atherosclerosis and the type of training may affect the response to these indicators. Therefore, the purpose of the present study was to investigate the effect of a continuous versus interval aerobic training session on plasma levels of intercellular adhesion molecules 1 (ICAM-1) and vascular cell adhesion molecules ...
[ 5 ] - Investigating the Protective Effect of an Interval Training on Neutrophilic Factors of BDNF and CDNF in Rats Fed with High-fat Foods
Background and Aim: Exercise targets the secretion of brain-derived neurotrophic factors and has a major impact on the overall health of the brain. The present study aimed to investigate the protective effect of a period of interval training on neutrophilic factors of BDNF and CDNF in rats fed with high-fat foods. Materials and Methods: In this experimental study, 42 male Wistar rats were rando...
[ 6 ] - Changes of the Patellar Tendon Moment arm Length in Different Knee Angles: A Biomechanical in Vivo Study
Patellar tendon moment arm length (PTma) changes at different knee flexion angles have not been determined in invivo studies. We aimed to determine PTma in four different knee angles using Magnetic Resonance Imaging (MRI) topredict in vivo changes in the moment arm length from different knee angles during running.PTma was measured as the perpendicular distance from muscle–tend...
[ 7 ] - Evaluation of Nutritional factors and body composition of selected athletic students of high school in Hamedan city
Introduction: Adolescence is one of the most sensitive and important periods of human development. At this stage, the growth suddenly increases. This rapid growth requires special nutritional needs. Nutritional knowledge is a process that can empower a person to use the information to improve the nutritional status and health of the individual. Nutrition culture forms the process of food consum...
[ 8 ] - Comparison of three aerobic exercise methods with different intensities on PPARγ2 gene expression in subcutaneous adipose tissue of male Wistar rats
Background and aims: PPARγ is one of the proteins that plays a very important role in regulating adipose tissue metabolism under physiological and metabolic conditions. Therefore, the aim of this study was to investigate the effect of three aerobic exercise methods of HIIT, HIT and MIT on the PPARγ2 gene expression in the subcutaneous adipose tissue of male Wistar rats. Methods: In this ...
[ 9 ] - The Effect of Different Intensities of Aerobic Exercise on the Expression of Darpp32 Markers in the Liver of Male Wistar Rat
Background & Aims: The liver, as the largest gland in the body, can manufacture, store, change and secrete a large number of metabolic substances the body. The liver receives blood rich in nutrients from the digestive and esophageal tracts, then stores them or changes them into chemical substances that are used elsewhere in the body for metabolic needs. This tissue is especially important in re...
[ 10 ] - Compare of Two Aerobic Training Methods on SOD and TNF-α levels in the Heart Tissue of Type 2 Diabetic Rats
The purpose of this study was to compare two methods of aerobic exercise on the levels of SOD and TNF-α in the heart tissue of diabetic rats. 40 male Wistar rats aged ten weeks were randomly divided into four groups of 10: healthy control, diabetes, diabetes+MIT and diabetes+HIT. The moderate intensity training group ran 5 sessions per week for 8 weeks on the treadmill for 60 minutes at a speed...
