مقدمه: تغییر در سوخت و ساز لیپیدها یکی از سازوکارهای مهم برای درمان مقاومت به انسولین و در نتیجه دیابت نوع 2 است. از سوی دیگر، pgc-1α به عنوان یکی از تنظیم کنندههای کلیدی بیوژنز و عملکرد میتوکندری، از راه افزایش بتا- اکسیداسیون لیپیدها، نقش مهمی در بهبود حساسیت به انسولین ایفا میکند. در پژوهش حاضر، اثرات اپیگالوکاتچین گالات (egcg)، به عنوان ترکیب ضدچاقی و افزاینده کاتابولیسم چربی، بر بیان ...
Background: In the previous decade, various benefits and biological activities of royal jelly, applied in alternative modern medicine, cosmetics, have been reported. However, effects jelly extract (RJ) on keratinocytes not fully elucidated. Objective: The primary objectives this study were to reveal RJ explore underlying mechanism. Methods: HaCaT cells, an immortal human epidermis-derived kerat...
based on the evidence regarding the relationship between inflammatory processes and stress responses, the present study investigated the association between psychological stress and elevation of inflammatory mediators related to periodontal disease in adult patients.the study consisted of 50 patients including 25 patients with chronic periodontitis and 25 cases with aggressive periodontitis. tw...
background: we aimed to reveal the role of cd11b and hypoxia-inducible factors-1alpha (hif-1α) expressions on monocytes and alveolar macrophages of lung tissue, and the levels of serum surfactant protein-d (sp-d) in severe malaria-associated acute lung injury (ali). methods: the c57bl/6 mice were divided into control group, renal malaria group (inoculated with 10 6 plasmodium berghei anka), and...
Objective: Decreased physical activity coupled with increased High‐Fat Diet (HFD) intake prompts obesity. Current research suggests that changing White Adipose Tissue (WAT) to brown promotes energy expenditure to counter obesity. The purpose of this study was to investigate the effects of aerobic Progressive training and Capsaicin (Cap) on Peroxisome proliferator-activated receptor gamma coacti...
Background: The purpose of this study was to compare the effects of a 12 weeks interval training with high and moderate intensity on PGC-1α of skeletal muscle in type 2 diabetic male rats. Methods: 40 male rats were divided into two groups: High fat diet (HFD) (n=32) and standard diet (C) (n=8) for 10 weeks. After inducing type2 diabetes via STZ, 8 diabetic rats (D) and 8 rats in group C rats ...
آزمایشی برای بررسی اثر افزودن متابولیت 1- آلفا هیدروکسی کولهکلسیفرول با و بدون کولهکلسیفرول و فیتاز میکروبی در جیرههای با سطوح مختلف کلسیم و فسفر بر عملکرد جوجههای گوشتی انجام شد. برای انجام این آزمایش تعداد 576 قطعه جوجه یک روزه نر (راس 308) با میانگین وزن 1±40 گرم انتخاب شدند. آزمایش در قالب طرح کاملا تصادفی به صورت فاکتوریل (3×2×2×3) با 4 تکرار و 4 جوجه در هر تکرار انجام شد. فاکتورها ...
Objective(s): Previous study has indicated that triiodothyronine (T3) facilitated cartilage degeneration in osteoarthritis (OA). This study aimed to investigate the effects of T3 on angiogenesis-related factor expression in human osteoblasts of OA subchondral bone.Materials and Methods: The subchondral bone specimens were obtained from O...
Hypoxia-inducible factor-1α (HIF-1α) is known as a transactivator for VEGF gene promoter. It can be induced by hypoxia. However, no study has been done so far to dissect HIF-1α-mediated effects from hypoxia or VEGF-mediated effects. By using a HIF-1α knockout (HIF-1α KO) cell system in mouse embryonic fibroblast (MEF) cells, this study analyzes cell migration and HIF-1α, hypoxia and VEGF activa...
Background: Obesity is associated with increased risk of many diseases. Methylation is an important factor in obesity, indicating epigenetic changes. However, there is lack of data about PGC-1α methylation and regular exercise. Purpose of this study was to determine effects of 6-week high-intensity interval training (HIIT) on PGC-1α methylation in gastrocnemius muscle of obese male rats. Metho...
