Background and Objective: Autophagy is a genetically and evolutionarily conserved the programmed process that destroys long-lived cellular proteins and organelles. This study aimed to evaluate the effect of eight weeks of strength training with alpha-lipoic acid supplementation on LC3-I and P62 in elderly diabetic rats.
Material and Methods: In this experimental study, 35 old male Wistar rats were randomly divided into 5 groups (healthy control, diabetic, diabetic + strength training, Diabetic + supplement, Diabetic + strength training + supplement). First, the rats became diabetic and had a fatty liver. Strength training program in 10 weeks performed. Alfa-lipoic acid supplement was also injected 3 days a week. At the end of the training period and tissues were removed and the expression of LC3-I and P62 were measured by RT-PCR. For data analysis, a one-way analysis variance test was used for comparison between groups was considered (P<0/05).
Results: The result showed mRNA LC3-1 has increased and this change is more in the diabetic group. (P=0.001) and  despite the decrease in P62 gene expression, we did not see a significant difference between the control group and the diabetic in the training group with and without supplementation.However, no significant difference was observed between training methods and supplementation with exercise. Also, resistance training in combination with alpha-lipoic acid supplementation had a significant effect on reducing P62 content between control and experimental groups. (P=0.001).
Conclusion: Alfa-lipoic acid supplement with anti-oxidant and anti-inflammatory effect along with exercise can play an important role in improving fatty liver in elderly type 2 diabetic rats.

Background: Alzheimer's is a neurodegenerative disorder characterized by memory loss and cognitive dysfunction. Research has shown that blood metal levels and physical activity may be key to injury and possibly Alzheimer's treatment. The aim of this study was to investigate the effects of high intensity interval training (HIIT) and Folate Nano-liposome on the expression of D1 and D2 receptors in the hippocampal tissue of Alzheimer's rats.
Methods: Thirty-three male Wistar rats at the age of eight weeks were prepared from Pasteur Institute. Rats were randomly divided into 5 groups (healthy control, Alzheimer's control, Alzheimer+ HIIT, Alzheimer +Folate Nano liposomes, Alzheimer+ HIIT +Folate Nano liposomes).Alzheimer's induction was performed and Folate Nano-liposomes were injected as a supplement .After the last training session, rats were anesthetized and the hippocampus was analyzed.
Results: The results of one-way ANOVA showed a significant increase between the groups in D1 mRNA and D2 mRNA (P≤0.000). The results of the Bonferroni post hoc test showed that there was a significant increase the control group and the Alzheimer's, Alzheimer's + HIIT and Alzheimer's +folate Nano liposomes. There was a significant increase between Alzheimer's group and Alzheimer's+ HIIT and Alzheimer's+ HIIT+ folate Nano-liposomes (P≤0.05).
Conclusion: Resistance training and Folate Nano-liposomes have changed the content of D1 and D2 in the brain after Alzheimer's induction. These changes may be due in part to the synergistic effect of physical activity and Nano-pharmaceuticals in preventing or reducing the detrimental effects of pathological conditions.
