Abstract
Background: The aim of the present study was to investigate the simultaneous effect of resistance training and stem cell injection on the levels of some indicators of skeletal muscle apoptosis in STZ-induced diabetic male rats.
Methods: In this study, 30 rats were randomly divided into 5 groups. Rats in the diabetic group and the diabetic group + stem cell injection had a total of 17 sessions of resistance training for 5 weeks. The training period for rats with this type of training was 3 days, which was done 48 hours before STZ injection. Western blotting was used to evaluate the changes in Caspase7 and caspase3. The data were analyzed using two-factor analysis of variance test with SPSS software version 19 at a significance level of α≤ 5%.
Results: The results of the present study showed that there was no significant difference between the mean of caspase3 in the resistance training group with simultaneous injection of stem cells and the training group. Also, resistance training with simultaneous injection of endothelial stem cells, compared to resistance training or injection alone, led to a significant reduction in Caspase7 expression in skeletal muscle tissue of diabetic rats.
Conclusion: Based on the results of this study, it can be stated that resistance training or injection of endothelial progenitor cells can stimulate apoptosis in skeletal muscle.

Abstract
Background: Fat mass and obesity-associated gene (FTO) is directly associated with increased risk of obesity and type 2 diabetes mellitus (T2DM). The purpose of this study was to investigate the effect of 12 weeks of high intensity interval training (HIIT) on FTO expression of subcutaneous fat tissue in T2DM rats.
Methods: In this experimental study, twelve males Wistar rats (220±10 g) with T2DM induced by streptozotocin-nicotinamide injection were randomly divided into exercise (n=6) and control (n=6) groups. The training group performed the HIIT protocol on a treadmill for 12 weeks and 5 days per week. FTO expression in subcutaneous fatty tissue, blood glucose level, insulin and insulin resistance were measured 48 hours after the last training session. Data were analyzed by independent T test at P< 0.05.
Results: Blood glucose level, insulin resistance and FTO expression in fat tissue decreased significantly in training groups compared to control group after the exercise intervention (P˂0.05). Serum insulin increased significantly in training groups compared to control group (P˂0.05).
Conclusion: It seems that HIIT can decrease glucose, insulin resistance and FTO expression of fat tissue of T2DM rats. Improved glycemic control in diabetic rats might be attributed to reduced FTO expression in response to HIIT.

Abstract
Background: Type 1 diabetes is a disorder caused by autoimmune destruction of pancreatic insulin-producing cells. This induction of autoimmunity may be due to genetic and environmental factors. Bax and Bcl2 proteins play an important role in the process of apoptosis.
Methods: In this study, 30 male Wistar rats weighting approximately 200±20gr were randomly selected from available rats in lab (500). Subjects after 2 weeks of familiarity with the environment were randomly divided into 5 groups of 6, including (diabetes + injection, exercise) and (diabetes + exercise) and (diabetes + injection) and (diabetes control to control the passage of time) and (basic diabetes to Defaults) under the same laboratory conditions and developed type 1 diabetes by intraperitoneal injection of streptozotocin (stz) (60 mg / kg). Rats in the diabetic group and the diabetic group + stem cell injection had a total of 17 sessions of resistance training for 5 weeks.
Results: The results of the present study showed that there was no significant difference between the mean of Bax and Bcl2 in the resistance training group with simultaneous injection of stem cells and the training group.
Conclusion: The results of our study showed that performing 17 sessions of resistance training alone with stem cell injection was effective on the expression of Bax protein and Bcl2, but there was no significant difference between the effect of training alone and training with stem cells.

Abstract
Background: Considering the increasing and alarming trend of overweight and obesity as well as its related complications, in this study, a comprehensive clinical guide for the medical care of patients with obesity was written based on the clinical recommendations of the American Endocrinology Association and the American College of Endocrinology, and it has been adjusted as much as possible based on the conditions in Iran.
Methods: A complete search was performed in the available databases without any restrictions with a specific strategy. Using the opinions of experts in this field, the best clinical guidelines were selected and obesity clinical guidelines were written for Iranian adults. Recommendations were given based on a detailed review of available clinical evidence and considering objective factors.
Results: A total of 1788 references were used and in response to 9 clinical questions, 123 recommendations, including 160 special statements, were provided to determine a comprehensive medical care program for obesity. In this article, we discuss the prevention, screening, diagnosis, benefits and goals of obesity treatment. Questions 6 to 9 regarding obesity treatment steps and its individualization will be published in the next part of the article.
Conclusion: The detailed evidence-based questions and recommendations outlined in this study identify clinical considerations that facilitate decision-making in obese patients from screening and diagnosis to goals of treatment.

Abstract
Background: The prevalence of overweight, obesity and related complications is increasing rapidly in the world. Also, treating this disease in the presence or absence of co-morbidities has become a challenge. In this article, based on the clinical recommendations of the American Endocrinology Association and the American College of Endocrinology, a comprehensive clinical guide has been written for the stages of treating obese patients and its individualization, and it has been tried to be adjusted as much as possible based on the conditions in Iran.
Methods: with a specific search strategy, a complete search was performed in PubMed, Scopus, ISI Web of Science, EMBASE and Google Scholar Cochrane databases. Then, the best clinical guidelines suitable for the Iranian society were selected and using the opinions of specialists and clinical experts, a clinical guideline was prepared for the treatment of obesity in Iranian adults.
Results: In this article, in continuation of the previous article, we answered the questions number 4 to 6 regarding the stages of obesity treatment and its individualization in adults of Iranian society, and presented a total of 60 recommendations in this regard.
Conclusion: In this part of the clinical guide for obesity in Iranian adults, we tried to have a special view on the treatment of these patients and by providing evidence-based recommendations and statements, the treatment process was personalized as much as possible for patients with special conditions so that decision-making in this regard is facilitated for the relevant colleagues in this field.

Abstract
Background: Transcription factor 7-like 2 (TCF7L2) is one of the strongest genetic risk factors associated with type 2 diabetes mellitus (T2DM). The purpose of this study was to investigate the effect of 10 weeks of high intensity interval training (HIIT) on hepatic TCF7L2 expression in T2DM rats.
Methods: In this experimental study, fourteen males Wistar rats with T2DM induced by streptozotocin-nicotinamide injection were randomly divided into exercise (n=7) and control (n=7) groups. The exercise group performed the HIIT protocol on a treadmill for 10 weeks and 5 days per week. Hepatic TCF7L2 expression, blood glucose level, hemoglobin A1c (HbA1c), insulin and insulin resistance were measured 48 hours after the last training session. Data were analyzed by independent T test at P< 0.05.
Results: Hepatic TCF7L2 expression and serum insulin were significantly higher in the exercise group compared to the control group (P˂0.05). Blood glucose level, HbA1c and insulin resistance were significantly lower in the exercise group than in the control group (P˂0.05).
Conclusion: Based on these findings, it seems that the improved glycemic control in response to HIIT is partially dependent on the inhibition of gluconeogenesis caused by increased hepatic TCF7L2 expression.
