[ 1 ] - Trans-chalcone enhances insulin sensitivity through the miR-34a/SIRT1 pathway
Objective(s): Trans-chalcone as the parent member of the chalcone series reduces circulating levels of insulin and glucose. However, the cellular mechanism of these effects is poorly understood. Sirtuin 1 (SIRT1) as a direct target of miR-34a controls homeostasis of glucose, and also improves insulin sensitivity. Therefore, the present study for the first time investigated the influence of trans-…
[ 2 ] - مروری بر مدل‌های پرکاری تیروئیدی در موش و موش صحرایی
Introduction: Humans can rarely be used as experimental models in medical researches, because of ethical issues. Therefore, some animal models, which have physiological systems similar to humans, are commonly used. In this regard, rats and mice are the most favorable species in research models. The thyroid gland has a key role in human growth and development and is essential for normal functionin…
[ 3 ] - مروری بر مدل‌های کم‌کاری تیروئیدی در موش صحرایی: مقایسه‌ی عملکرد تیروئید در موش صحرایی و انسان
Introduction: Human subjects can not always used as models for studying disease by researchers because of the potential risks for human health, and in addition, control of interfering factors is not easy in these subjects. Animal biology, physiology, anatomy, biochemistry, pharmacology, and genetics are very similar to humans. Animals are suitable models for research, as their functional body sys…
[ 4 ] - Effect of vitamin C on tracheal responsiveness and pulmonary inflammation in chronic obstructive pulmonary disease model of guinea pig
Introduction: In the present study, the prophylactic effect of vitamin C, as a potent anti-oxidant, on tracheal responsiveness to methacholine and ovalbumin, bronchoalveolar lavage fluid white blood cell (WBC) count and differential count, and also lung pathology in chronic obstructive pulmonary disease (COPD) -guinea pigs (cigarette exposed guinea pigs) were examined. In addition, the relaxan…
[ 5 ] - اثر تجویز طولانی مدت نیترات سدیم با دوزهای بالا بر شاخص‌های چاقی در موش‌های صحرایی ماده
Introduction: Despite higher prevalence of obesity in women, the anti-obesity effects of nitrate have mostly been studied in male animals, using low doses of nitrate for short durations. This study aims at determining effects of long-term (6 months), administration of high doses of nitrate on the obesity indices of normal adult female rats. Materials and Methods: Female Wistar rats were divided i…
[ 6 ] - بررسی اثر تیروتوکسیکوز بر بیان ژن آنزیم‌های تولیدکننده‌ی سولفید هیدروژن در بافت چربی اپیدیدیمال موش صحرایی نر
Introduction: Thyroid hormones are involved in the regulation of hydrogen sulfide (H2S) biosynthesis. The aim of this study is to determine effects of thyrotoxicosis on H2S levels and mRNA expression of cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST) in the adipose tissue of rat. Materials and Methods: Male rats were divided into the co…
[ 7 ] - اثر پرکاری تیروئید شدید بر غلظت آنزیم‌های تولیدکننده‌ی اکسید نیتریک در کبد موش‌های صحرایی نر
Introduction: Thyroid hormones play an important role in normal function of liver and hyperthyroidism can cause liver dysfunction. Thyroid hormones affect nitric oxide (NO)-producing enzymes in liver. The aim of this study is to investigate effects of hyperthyroidism on protein levels of three isoforms of NO synthase (NOS) enzymes, including endothelial NOS (eNOS), inducible NOS (iNOS), and neuro…
[ 8 ] - اثر تجویز طولانی‌مدت نیترات سدیم خوراکی بر غلظت آنزیم-های کبدی در موش‌های صحرایی نر دیابتی نوع 2
Introduction: Liver disorders in patients with type 2 diabetes (T2D) are mostly associated with higher serum levels of liver enzymes. This study aimed to investigate the effect of nitrate administration on the serum levels of alanine amino transferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) in rats with T2D. Materials and Methods: In this study, 24 male Wistar rats…
