Abstract
Background: Damage to the heart tissue in diabetics causes inflammation and destruction of heart cells, which in turn leads to apoptosis or cell death. The aim of this study was to investigate compare the effect of six weeks of aerobic and resistance training on apoptotic indice of caspase-8 and catalase in the heart tissue of male diabetic rats.
Method: In this experimental study, 24 male Wistar rats were divided into six groups: aerobic training, resistance training, aerobic sham, resistance sham, control and healthy. Diabetes was induced by intraperitoneal injection of a single dose of streptozotocin in the amount of 30 mg per kg. The aerobic and resistance training program was performed for six weeks. Western blotting was used to measure caspase-8 and catalase. Data were analyzed by one-way analysis of variance and Tukey post hoc test at the P<0.05.
Results: The results showed that the mean difference of caspase-8 between aerobic training group and healthy group (P=0.752), resistance training group with healthy group (P=0.723) and resistance training with aerobic training group (P=1.00) were significant. Caspase 8 was lower in the aerobic exercise group than in the resistance exercise group. The difference between the mean catalase between the aerobic training group with the healthy group (P=0.024) and the aerobic training group with the resistance training group (P=0.023) was significant and the amount of catalase in the resistance training group was higher than aerobic training.
Conclusion: Aerobic and resistance training can reduce the apoptotic index of caspase-8 and increase catalase in the heart tissue of diabetic rats.

Abstract
Diabetes is a serious public health problem in low- and middle-income countries. There is a strong association between hyperglycemia, oxidative stress and the development of diabetes. Therefore, screening and early diagnosis of this disease in people at high risk can be effective in preventing these complications. The main route of insulin signaling is to control lipid and glucose metabolism, and its imbalance leads to type 2 diabetes. P-Cymene is an aromatic monoterpene with a wide range of therapeutic properties including antioxidant activity. The aim of this study was to evaluate the effect of p-Cymene at a dose of 50 mg / kg in preventing the symptoms of diabetes and serum factors.
Materials and Methods: 30 male Wistar rats weighing approximately 250 g were randomly selected and divided into five groups: control, diabetic control (sham), metformin-treated diabetic (met), and non-diabetic treated. P-Cymene and diabetics treated with P-Cymene were divided. One week after streptozotocin injection, treatment with P-Cymene at a dose of 50 mg / kg was performed by sunflower oil solvent for 28 days by gavage. At the end of the experiment, blood samples were taken from the hearts of rats and the parameters of glucose, insulin, and superoxide dismutase (SOD) were measured.
Results: The results showed that diabetes increased water and food intake as well as glucose levels and decreased insulin (P <0.001) and superoxide dismutase activity in rats and administration of P-Cymene extract improved the symptoms of diabetes and oxidative stress in Became diabetic rat.

Abstract
Background: The present study was conducted to investigate the effect of eight weeks of aerobic training and vitamin D3 supplementation on cardiac irisin protein levels, insulin resistance and lipid profile in rats induced with type 2 diabetes.
Methods: Forty male Wistar rats after induction of type 2 diabetes through the combination of high-fat diet +streptozotocin were randomly divided into five groups: 1) Normal control (NC) ,2) Diabetic Control (DC), 3) Diabetes+ Aerobic Training (DAT) ,4) Diabetes+ Vitamin D3 (DVD) and 5) Diabetes+ Aerobic Training+ Vitamin D3 (DVDAT). Aerobic training program (five times a week with 60% intensity of maximum running speed for one hour) and vitamin D3 supplementation (10000 IU/kg every week) were performed. After anesthetizing the rats, blood samples were taken to evaluate serum glucose, insulin, triglyceride, cholesterol, LDL and HDL levels. The heart tissue was isolated to evaluate the irisin.protein.
Results: The results of the one way analysis of variance showed that the irisin protein level of the heart tissue in DAT, DVD and DVDAT groups had a significant increase of 14.04, 12.28 and 24.56%, respectively compared to DC (P<0.001). Insulin resistance also showed a significant decrease in all intervention groups compared to the DC group (P<0.001); However, HDL, triglyceride and cholesterol levels were significantly decreased in DAT and DVDAT groups compared to DC group (P<0.001).
Conclusion: According to the results, it seems that eight weeks of aerobic training and vitamin D3 supplementation probably improves the insulin resistance index and lipid profile in rats induced to type 2 diabetes through increasing the cardiac irisin.

Abstract
Background: Glucose transporter4 (GLUT4) is the main glucose transporter in skeletal muscle. Impaired GLUT4 expression plays a role in the disorders of glycemic homeostasis. The aim of the present study was to investigate the combined effects of aerobic training and vitamin D3 supplementation on Glut4 protein levels and insulin resistance in the soleus muscle of diabetic rats with STZ and high-fat diet.
Methods: In 40 male Wistar rats type 2 diabetes was induced by 6 weeks high-fat diet followed by streptozotocin injection. Then rats were randomly divided into five groups: Healthy control (HC), Diabetic control (DC). Diabetes+Aerobic training (DAT), Diabetes+Vitamin D3 (DVD) and Diabetes+Aerobic training+ Vitamin D3 (DVDAT). The rats underwent eight weeks of aerobic training and vitamin D3 supplementation. 24h after last session of training and, the rats were anesthetized and soleus muscle was isolated for measurement of Glut4 protein concentrations and serum levels of insulin, glucose, vitamin D3 index were measured.
Results: One-way ANOVA showed that GLUT4 protein levels in DC group was significantly lower than HC group (P<0.001), but in DVDAT group was significantly higher than DC group (P<0.04) and DVD group (P<0.005). Also in DAT group was significantly higher than DVD (P<0.018). The HOMA-IR index also in DVDAT, DAT and DVD groups was significantly lower than DC group (P<0.001).
Conclusion: It seems that Eight weeks of aerobic training with vitamin D3 supplementation improves glucose metabolism in diabetic rats via increasing Glut4 protein levels and improving insulin resistance index.

Abstract
Background: Metabolic syndrome is characterized by a cluster of conditions such as abdominal obesity, high triglycerides, high blood pressure, high blood sugar, and low levels of healthy fat. Therefore, this study aimed to investigate the effect of endurance training on PGC1α protein content, glycosylated hemoglobin and metabolic syndrome indices in obese rats with type 2 diabetes.
Methods: Eighteen male Wistar rats with an average weight of 200±20 g were selected and placed on a high-fat diet for four weeks. Then 12 rats were randomly selected and induced type 2 diabetes by injecting nicotinamide (110 mg/kg) and streptozotocin (50 mg/kg) solutions. Diabetic rats were randomly divided into two groups of training and control patients. The samples of the training group performed endurance training on the treadmill for 8 weeks and 5 sessions every week with an intensity of about 50 to 70% of the maximum speed. 48 hours after the last training session, mice were sacrificed and variables were measured. To analyze the data, one-way ANOVA and Tukey's post hoc tests were performed in SPSS software version 29.
Results: Endurance training led to a significant decrease in fasting blood sugar levels, HbA1c and triglyceride levels (P= 0.0001). On the other hand, it did not show any effect on HDL levels (P= 0.087). On the contrary, it led to an increase in the intracellular amount of PGC-1α (P= 0.0001).
Conclusion: The results show that endurance training can be considered as an adjuvant drug by regulating the factors related to metabolic syndrome.

Abstract
Background: Moderate and intense aerobic exercise increases the production of free radicals, and on the other hand, the use of antioxidant supplements such as grape seed extract (GSE) has been suggested as one of the ways to deal with oxidative stress. Based on this, the aim of this study was to determine the interventions effect of combined exercise and consumption of GSE on some factors of oxidative and antioxidant stress in postmenopausal women with type 2 diabetes.
Methods: The current study was conducted as a clinical trial on the 80 women with type 2 diabetes, who were randomly divided into four groups (20 people): control, exercise, GSE supplement, exercise + GSE supplement. The combined exercise protocol consisted of aerobic (20 minutes of treadmill running at an intensity of 60–70% of reserve heart rate) and strength training (at an intensity of 70% of one repetition maximum), which was performed for eight weeks (five days/week). GSE supplement was taken in the form of 200 mg capsules daily (morning and noon). Samples (five cc) were taken before and after eight weeks of interventions. In order to determine the acceptance or rejection of the null hypothesis of intragroup and intergroup changes, was used the two-way AVOVA, and then Tukey's post hoc test to determine different groups by SPSS version 25 (P≤ 0.05).
Results: The values of total antioxidant capacity (TAC) and serum glutathione reduction (GSH) in the GSE and exercise + GSE groups increased significantly compared to the control and exercise groups (P= 0.001). Serum malondialdehyde (MDA) levels in the GSE group showed a significant decrease compared to the control and exercise groups (P= 0.001).
Conclusion: It seems that the intervention of grape seed extract is more effective in reducing oxidative stress than combined exercise. The consumption of this extract alone, as well as with combined exercise, has a significant effect on increasing the total antioxidant capacity and reducing GSH (glutathione).

Abstract
Background: The increasing trend of diabetes patients requires lifestyle interventions to improve the self-management ability of these patients, and achieving this requires the use of valid tools in this field. This study aimed to determine the psychometric properties of the Comprehensive Diabetes Self-Management Scale (CDSMS) in patients with type 2 diabetes.
Methods: The present study was methodological research that was conducted in 2023. At the beginning of the work, the CDSMS questionnaire was translated into Persian using the standard translation-back translation method. Then, face validity, content validity, convergent validity, internal consistency, and instrument stability were determined. Data analysis was performed using descriptive statistics, Cronbach's alpha calculation, Kappa index, Pearson correlation coefficient, and intra-cluster correlation coefficient in SPSS software version 24.
Results: Based on the results, all the items of the instrument were retained. The total content validity index score of the Persian version of this questionnaire was 0.987. Also, the Kuder-Richardson and Kappa indices were 0.704 and 0.730, respectively. The level of agreement at two measurement times, two weeks apart, ranged from 0.503 to 0.990. The intra-cluster correlation index was also observed to be in the range of 0.625 to 0.952 and was significant (P < 0.001). The Cronbach's alpha coefficient of the instrument was also 0.83.
Conclusion: The results of the present study showed that the Persian version of the CDSMS questionnaire with 14 items has good validity and reliability and can be used to evaluate the self-management status of patients with type 2 diabetes in Iran.
