Abstract
Disruption of the homeostasis of immune regulatory mediators Aryl hydrocarbon receptor (AhR) and Ornithine decarboxylase-1(ODC-1) is involved in the pathogenesis of multiple sclerosis (MS). Physical activities play a role in controlling and improving the symptoms of MS. This study was conducted in order to investigate the effect of 4 weeks of physical activity in an enriched environment on the gene expression of AhR and ODC-1 in the cerebellum tissue of an MS mice model. This experimental study was conducted on 30 female C57BL/6 mice. Mice were divided into 3 groups of 10 including 1) healthy control, 2) experimental model of MS and 3) physical activity in enriched environment. After induction of experimental autoimmune encephalomyelitis (EAE), the third group lived in the enriched environment for 4 weeks. Body weight and clinical score were recorded daily from induction until 28 days. The gene expression of AhR and ODC-1 in the cerebellum was measured by RT-PCR method. Statistical analysis of the data was performed using one-way analysis of variance at a significance level of less than 0.05. Activity in the enriched environment significantly decreased the gene expression of AhR compared to the EAE group (P=0/02) and also decreased the gene expression of ODC-1, but it was not statistically significant (P=0/28). Also, the clinical score improved significantly after activity in the enriched environment (P= 0/001). Lifestyle change and activity in the enriched environment led to the down regulation of the gene expression of AhR and ODC-1, and it improved the clinical score of animals.

Abstract
Aim and Background: Ankle is one of the most common sports injuries caused by direct collisions with opposing players or the ground, tackles from inside and outside, jumping and landing. Among these injuries, external ankle sprain is one of the most common injuries that is associated with ankle instability. The purpose of this research is to compare balance exercises and hopping on the proprioception of athletes with functional ankle instability.
Materials and methods: 30 athletes with functional instability of the ankle were randomly divided into 2 study groups of the clinical trial. The first group included athletes with functional ankle instability doing hopping exercises (15 people), the second group included athletes with functional ankle instability doing balance exercises (15 people). At first, the proprioception of their ankle joint was evaluated with the help of photography, and then they did exercises for 6 weeks, and at the end, the proprioception of the ankle joint was evaluated again. SPSS version 20 software was used to analyze the data of this research.
Results: The results showed that balance and hopping exercises significantly reduced the absolute error of ankle dorsiflexion and plantarflexion reconstruction (p<0.05). Also, there is a significant difference between the two groups of balance exercises and hopping (p<0.05).
Conclusion: The results of the present study showed that balance and hopping exercises improved the proprioception of the ankle joint in athletes with functional instability of the ankle, and hopping exercises are more effective than balance exercises.

Abstract
Neurodegenerative processes play an important role in the progression of MS. Appropriate exercise training and living in an enriched environment (EE) can improve or prevent the progression of the disease through the secretion of some neurodevelopmental factors in the hippocampus, including irisin and the neutrophic factor derived from the mouse. The aim of the present study was to investigate the effect of 4 weeks of aerobic and resistance training and EE on irisin protein and hippocampus BDNF levels in female C57BL6 mice with experimental autoimmune encephalomyelitis (EAE). 50 female mice (age 8 weeks, average weight 18 ± 2 grams) were randomly divided into five equal groups (10 mice in each group): 1- healthy control, 2- control + EAE, 3- resistance activity + EAE, 4- Aerobic activity + EAE and 5- EE + EAE. The first and second weeks of adaptation to the environment and then induction of EAE were performed. The training groups trained 5 days a week for half an hour a day for 4 weeks, and the EE group was transferred to its equipped cage. 48 hours after the last training session, the mice were anesthetized and then dissected and tissue removed. The ELISA method was used to measure the amounts of proteins, and the analysis of variance and Tukey's t-test were used to determine the differences between the research variables. All analyzes were performed at a significance level of 0.05 and with SPSS22 software. Hippocampal BDNF expression was increased in all three training groups compared to the EAE control group. This increase in the EE and resistance training group was significant compared to both the EAE control group and the swimming training group. Also, hippocampal irisin expression increased in all three training groups compared to the EAE control group, and this increase was significant in the EE and resistance training groups. Also, the expression of irisin in the EE group increased more than the two aerobic swimming and resistance training groups, and this increase was proportional to It was meaningful to the swimming aerobic training group. It seems that EE and resistance training can increase the secretion of nerve growth factors such as irisin and BDNF and thus help to improve MS disease.

Abstract
Fatigue is one of the most common symptoms among individuals with multiple sclerosis (MS). The imbalance of inflammatory cytokines in the brain causes mental fatigue. It is believed that aerobic exercise may moderate the level of inflammation of cytokines and thus reduce mental fatigue. This study was conducted to investigate the effect of swimming aerobic training on pro-inflammatory factors (interleukin 6) and anti-inflammatory factors (interleukin 10) to evaluate mental fatigue in the brains of female mice after EAE induction. In this research, 21 mice (8 weeks old, 18 to 20 grams) were divided into three groups: healthy control, EAE control, and EAE swimming aerobic exercise. The animals in the training group performed moderate-intensity swimming exercises for 4 weeks, with 5 sessions per week, each session lasting 30 minutes. The western blot method was used to analyze the research variables. The results showed no significant difference in the amount of IL-6 between the EAE group and the swimming training group, but the amount of IL-10 in the swimming training group showed a significant increase compared to the EAE group. The ratio of IL-10/IL-6 values between the swimming training group and the EAE group was also not significant. It seems that moderate-intensity swimming aerobic exercises, without changing the pro-inflammatory factor, along with increasing the anti-inflammatory factor IL-10, can lead to an improvement in the balance of the inflammatory index and a reduction in fatigue in the EAE group and the swimming exercise group.
