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: The aim of this study was to investigate the effect of eight weeks of circuit resistance training and saffron supplement on visfatin serum levels and insulin resistance in overweight men.
Methods: In this semi-experimental study, 40 obese and overweight students were randomly divided into 4 groups: exercise, exercise+supplement, supplement and control (10 people in each group). The exercise groups performed circular resistance exercises for eight weeks and three sessions each week for 90 minutes in the evening. The supplement and exercise+supplement groups used saffron tablets with a dose of 30 mg per day as a supplement. Blood samples were collected in two phases of the pre-test and 48 hours after the last training session. The data were analyzed using covariance and paired t test at a significant level of P≤0.05.
Results: Correlated t results showed a significant decrease in visfatin and insulin resistance in the post-test of the training, training+supplement and supplement groups compared to the pre-test (P<0.05). The results of the analysis of covariance showed that visfatin increased and the insulin resistance index decreased significantly in the exercise, exercise+supplement and supplement groups compared to the control group (P<0.05).
Conclusion: It seems that eight weeks of circuit resistance training and the addition of saffron help on visfatin serum levels and insulin resistance can lead to the reduction of these two variables in overweight men. The saffron plant can play a protective role due to the presence of flavonoids and by stimulating the secretion of Visfatin.

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.
