Abstract
Background and objectives: Physical activity has long been considered as the cornerstone of interventions for reducing the burden of cardiovascular diseases (CVDs). Homocysteine and obesity indices are important indicators of CVD risk. The present research aimed to evaluate homocysteine and obesity variables in female CVD patients and healthy counterparts with different physical activity levels.
Methods: This study was carried out on 85 CVD patients (40-55 yr, n=41, 60-75 yr, n=44) and 80 healthy women (40-50 yr, n=40, 60-75 yr, n=40). Subjects were divided into three groups based on their physical activity level: sedentary, moderately active and active. Serum homocysteine, body roundness index (BRI), a body shape index (ABSI), body mass index (BMI) and waist circumference (WC) were measured. Data were analyzed using the independent t-test and one-way ANOVA.
Results: Physically active middle-aged CVD patients had significantly lower BRI (p=0.022) and homocysteine (p=0.008) levels compared with the sedentary counterparts. In addition, physically-active old CVD patients had significantly lower BRI (p=0.041), ABSI (p=0.011) and homocysteine (p=0.001) compared with the sedentary counterparts. Physically-active healthy middle-aged individuals had significantly lower BRI (p=0.013) and BMI (p=0.008) levels compared with sedentary counterparts. Active elderly subjects also had significantly lower BRI (p=0.001) and WC (p=0.008) compared with the sedentary counterparts.
Conclusion: Physical activity can reduce the risk of CVD and improve health status of women by reducing homocysteine, BRI and ABSI.

Abstract
Background and objectives: Programmed autophagy is a genetically and evolutionarily conserved process that destroys long-lived cellular proteins and organelles. This study aimed to investigate effects of continuous and interval exercise training with or without atorvastatin supplementation on Beclin1, LC3-I and LC3-П expression in old rats with type 2 diabetes.
Methods: Sixty three male Wistar rats were divided into eight groups. Continuous exercise was performed at a speed of 15-29 m/min for 5-22 minutes. Interval exercise program consisted of six 2.5-minute sets that included a four-minute rest period between each set. The rats in the supplementation groups also received 20 mg/kg body weight atorvastatin daily via intraperitoneal injection. At the end of the training period, the expression of Beclin1, LC3-I and LC3-П in soleus muscle was measured by RT-PCR. One-way ANOVA was used for data analysis at statistical significance of 0.05.
Results: The results showed that both exercise trainings with or without atorvastatin significantly reduced LC3I, LC3-II and Beclin1 compared with the diabetic control group (P<0.05). In addition, the effects of the trainings and atorvastatin supplement did not differ significantly (P>0.05).
Conclusion: The results indicate that continuous and interval exercise program alone and combined with atorvastatin supplementation could significantly reduce LC3-1, LC3-II and Beclin1 level in soleus muscle of old diabetic rats.

Abstract
Background: One of the causes of infertility is azoospermia. The present study aimed to investigate the effects of swimming exercise, cell therapy, and laser therapy on the expression of genes involved in mitochondrial dynamics in the testicular tissue of azoospermic rats.
Methods: In this experimental study, 40 rats (6-8-weeks old) were randomly assigned to 8 groups: 1) Healthy control, 2) patient, 3) sham, 4) laser, 5) exercise, 6) cell, 7) cell + laser, and 8) cell + exercise. The azoospermia model was induced using busulfan at a dose of 40 mg. Stem cells were transplanted once into the vas deferens at a concentration of 1000000 cells per rat. One week after cell transplantation, laser therapy was applied in three repetitions throughout the study period, with an interval of once a week, and after wound healing, the rats swam for 30 minutes a day, 5 days a week, for 8 weeks. To investigate the expression of the studied genes, tissue analysis was performed by the real-time polymerase chain reaction (RT-PCR) technique.
Results: Azoospermia significantly reduced the expression of mitofusin 2 (Mfn2) and significantly increased the expression of dynamin-related protein 1 (Drp1) and muscle-specific RING finger protein 1 (Murf1) in testicular tissue. The use of interventional methods increased the expression of Mfn2, and significantly reduced the expression of Murf1.
Conclusion: Based on the findings, the best changes were observed in the exercise + laser group. Therefore, it can be said that in rats using the azoospermia model, the simultaneous use of regular exercise interventions and laser therapy is the most effective.

Abstract
Background: Running and starvation can have a positive effect on the reticulophagy of the liver tissue. The purpose of this research was to investigate the effect of running and starvation interventions on the atherogenic index and Xbp1 gene change in the liver endoplasmic reticulum of non-alcoholic fatty liver rats (NAFLD).
Methods: Thirty obese male Wistar rats aged 18-20 weeks with an average body weight of 348 ± 25.53 grams, after one week of familiarization with the laboratory environment, were randomly divided into six groups (n=5 per group): 1) starvation, 2) three days of training, 3) five days of training, 4) three days of training plus starvation, 5) five days of training plus starvation, and 6) the control group. All fatty liver animal models had free access to water and standard food pellets (10 gr per 100 g of mouse body weight). The statistical test of one-way analysis of variance was used at a significance level of less than 0.05, and the LSD post-hoc test was used to compare research groups.
Results: According to the experimental results and statistical analyses (One-way analysis of variance), a significant decrease was noticed in the ratio of lipoproteins (VLDL/HDL and LDL/HDL) in all experimental groups compared to the control group. Also, a significant decrease was observed in the expression of XBP1 and CHOP genes in animals doing 3 and 5 days of exercise alone or along with starvation.
Conclusion: Regular exercise for 3 and 5 days per week with starvation can possibly reduce the activity of the genes involved in endoplasmic reticulum stress in NAFLD patients.
