Background: Diabetes causes nerve tissue damage and ultimately death of nerve cells, especially in important areas such as the hippocampus. It seems that exercise training and anti-inflammatory supplements can moderate this condition. Therefore, the aim of this study was to determine the effect of aerobic training exercise and L-carnitine consumption on the levels of hippocampus CNTF and CNTFR proteins in diabetic rat.
Methods: 45 Wistar rats between 250 to 300 gr were randomly divided into six groups, including healthy control groups, sham, diabetic control, diabetes + aerobic exercise, diabetes + L-carnitine supplementation and diabetes + aerobic exercise + L-carnitine supplementation. L-carnitine supplements were divided. Diabetic groups underwent subcutaneous injection of 55 mg / kg STZ. supplementary groups received 100 mg of L-carnitine per day orally. The aerobic exercise program was performed for 6 weeks and 5 days a week. The research variables were measured 24 hours after the last training session by the ELISA technics in the hippocampal tissue. The statistical method of one-way analysis of variance and Toki post –hoc test were used to analyze the data.
Results: The present study showed an significant increase in CNTF and CNTFR protein levels of hippocampal tissue after aerobic exercise and L-carnitine consumption (P = 0.001), which greater effect found in combination manner.
Conclusion: Due to the effect of aerobic exercise and L-carnitine supplementation alone and in interaction with each other on hippocampal tissue, the use of this method can be considered as maintaining neural tissue in diabetes.

Background: One consequence of diabetes mellitus is increased inflammation, which is exacerbated by training. The objective of this study was to evaluate the effect of eight weeks of aerobic moderate-intensity continuous training on Interleukin-1 beta, Interleukin-13 responses in male Wistar diabetic rats.
Methods: 36 diabetic rats were randomly assigned into 3 equal groups (control (C), diabetic (D), and diabetes + training (D + T)), and subjected to eight weeks of aerobic moderate- intensity continuous training intensity at the first: the10 min on 10m/min and at the final: 55min on 26m/min speed. Interleukin-1 and interleukin-13 were measured in soleus muscle tissue to examine the pro-inflammatory and anti-inflammatory indicators. ANOVA and Scheffe post hoc tests were used for data analysis.
Results: Induction of diabetes caused a significant increase in IL-1β and IL-13 (P<0.001) and continuous exercise intervention also significantly reduced IL-1β levels in diabetic rats (P = 0.02). However, there was no significant change in IL-13 in D + T group compared to D group (P = 0.985).
Conclusion: According to the results of this study, the effect of aerobic exercise is probably a positive effect on reducing the pro-inflammatory index of IL-1β and no effect on the anti-inflammatory index of IL-13 in diabetic rats. However, definitive confirmation of these results requires further research in this area.

Background: One of the most common problems in diabetic patients is muscle atrophy. Therefore, the present study aimed to investigate the synergistic effect of endurance training with probiotic supplementation on Atrogin-1 and MuRF-1 genes gene expression in the soleus muscle of diabetic rats.
Methods: In this study, 32 male Wistar rats were randomly divided into one normal control (NC) and four diabetic groups: diabetic control (DC), diabetic supplement (SDC), diabetic training (TD), and diabetic supplement training (STD). The training protocol was performed with 60 to 65% of maximum speed reached five days a week for four weeks. At the same time, rats took two grams of probiotic dissolved in 30 ml of water daily. Expression of Atrogin-1 and MuRF-1 genes was measured by the qReal-TimePCR method. Data were analyzed by two-way analysis of variance at the significant level of P≤0.05.
Results: Atrogin-1 gene expression was significantly reduced in TD (P=0.001) and STD (P=0.000) groups compared to DC group. There was a significant difference between TD and STD groups in the expression of the Atrogin-1 gene (P=0.028). MuRF-1 gene expression was significantly reduced in TD (P=0.04) and STD (P=0.01) groups compared to DC. But there was no significant difference between TD and STD groups in MuRF-1 gene expression (P=0.36).
Conclusion: It seems that performing the aerobic exercise with probiotic supplementation is more effective in reducing the expression of the Atrogin-1 gene than any of these interventions alone. However, aerobic exercise with probiotic supplementation does not have a synergistic effect on reducing MuRF-1 gene expression in the soleus muscle of diabetic rats compared to aerobic exercise alone.

Background: Adipulin is a hormone secretd by fat cells that acts as a metabolic regulator with anti-inflammatory properties and is reduced through obesity, diabetes and inflammation. Therefore, the aim of this study was to compare the effect of high and moderate intensity aerobic exercise on serum adipolin levels and some indicators of metabolic syndrome in obese women.
Methods: In this quasi-experimental study, 36 people were randomly divided into three groups of 12 people (2 experimental groups and one control group). Aerobic exercise group with an intensity of 85-95% of maximum heart rate performed intermittent walking and running on the treadmill for 33 minutes per session and exercise group with an intensity of 50-70% of maximum heart rate walked continuously for 41 minutes. (Training duration for 2 groups was 8 weeks and 3 sessions per week, The control group was not active during this period). One-way analysis of variance statistical and Bonferroni post hoc tests were used at the significant level (P> 0.05).
Results: High intensity aerobic exercise significantly increased serum adipolin levels (P= 0.001) and decreased total cholesterol (P= 0.020), triglyceride (P= 0.021) and insulin resistance (P= 0.001). The results also showed no significant differences in the levels of high-density lipoprotein (P= 0.615), low-density lipoprotein (P= 0.604), and blood pressure (P= 0.269) in the three groups. Medium-intensity aerobic exercise had no effect on serum adipoline levels (P= 0.192), only glucose, (P= 0.025), triglycerides (P= 0.010), systolic blood pressure (P= 0.028) and insulin (P= 0.043) decreased and the levels of cholesterol, low-density lipoprotein and high-density lipoprotein did not change significantly.
Conclusion: In the end, it can be said that it seems that individuals can use high-intensity aerobic exercise to increase the amount of adipolin as an indicator of improving insulin sensitivity and also improving the indicators of metabolic syndrome.

Background: The aim of this study was to evaluate the effect of eight weeks of endurance training and Empagliflozin consumption on inflammatory markers and their relationship with heart structure and function of diabetic male Rats.
Methods: 40 male Wistar rats were randomly divided into five groups: healthy control, diabetic control, diabetic + empagliflozin, diabetic + endurance training and diabetic + endurance training + empagliflozin. The groups were anesthetized and their cardiac function and TNF-α and TGF-β indices were evaluated by one-way ANOVA and Pearson correlation tests after performing the training protocol and receiving medication.
Results: There were significant differences in left ventricular end systolic thickness (P = 0.011), left ventricular end systolic volume (P = 0.008), TNF-α (P = 0.014) and TGF-β (P = 0.001) was observed between the research groups. Also, there was a significant negative relationship between TGF-β with body weight, heart fiber shortening percentage and injection fraction and a significant positive relationship with glucose levels, left ventricular end systolic thickness and left ventricular end systolic volume. In addition, a significant negative correlation was observed between TGF-β and the injection fraction (P≤0.05).
Conclusion: Aerobic exercise seems to improve the inflammatory status, structure and function of diabetic heart tissue beyond the dual effect of Empagliflozin.

Background: Chronic hyperglycemia is associated with an increase in cellular damage due to oxidative stress and increases insulin resistance and also increases in p53 and p16 beta cells, leading to the induction of senescence in pancreatic insulin-secreting cells. The aim of this study was the effect of eight weeks of aerobic exercise on the expression of senescence proteins P53 and P16 in the pancreatic tissue of diabetic mice.
Methods: In this study, 15 NMRI mice (26.3 ±3.22 g) were divided into three groups randomly: healthy control, diabetic control and diabetic exercise. They were diabetic by HFD for 5 weeks and intraperitoneal injection of STZ. The aerobic training protocol (50-60% Vmax) was 5 days a week for 8 weeks. After anesthesia, blood and pancreatic tissue were removed. Insulin resistance, P53 and P16 protein concentrations in pancreatic beta cells were measured. Data were analyzed by ANOVA with a significance level of p <0.05.
Results: According to the results of eight weeks of aerobic exercise by mice diabetic type 2, a significant decrease in insulin resistance (p = 0.005), protein concentrations of P53 (p = 0.002) and P16 (p = 0.010) in pancreatic tissue was observed.
Conclusion: Aerobic exercise may improve insulin sensitivity and delay cellular senescence due to diabetes by reducing cell senescence factors such as P53 and P16 in beta cells. Therefore, this type of exercise can be considered as a therapeutic approach to improve the condition of these patients.

Background: Irisin is a myokine that is released from FNDC5 membrane protein and has positive effects on carbohydrate metabolism. The aim of this study was to evaluate the effect of 8 weeks of aerobic exercise on irisin levels and insulin resistance in middle-aged women with type 2 diabetes.
Methods In this quasi-experimental study, 24 women with type 2 diabetes were purposefully selected and randomly divided into two groups of aerobic exercise (n = 12) and control (n = 12). The training group performed aerobic exercises for 8 minutes (3 sessions per week) for 50 minutes with an intensity of 45-85% of the maximum heart rate on the treadmill. The control group did not engage in any physical activity during exercise. Blood samples were collected 24 hours before and 48 hours after the last training session and the serum was used to measure the levels of irzin, insulin resistance index (HOMA-IR), fasting glucose and insulin. Correlated t-test and independent t-test were used to examine intra-group changes and differences between groups. Data analysis was performed using SPSS software (version 22) at a significant level (P≥0.05).
Results: Intragroup changes showed that 8 weeks of aerobic exercise increased serum levels of irizin (P = 0.000), significantly decreased insulin resistance index (HOMA-IR) (P = 0.000), fasting glucose and insulin ratio (P = 0.001) ratio He became diabetic in the control group. Also, in comparison between groups, aerobic exercise caused a significant increase in levels of irizin (P = 0.001) and a decrease in insulin resistance index (HOMA-IR), fasting glucose (P = 0.001) and insulin (P = 0.001) compared to the control group. He became diabetic.
Conclusion: Aerobic exercise, through its beneficial effect on increasing irisin levels and decreasing insulin resistance index, is an effective factor in improving glucose metabolism in type 2 diabetic patients.

Background: A high-fat diet causes hyperinsulinemia and increases insulin resistance in the body. On the other hand, the oxidative stress caused by hyperglycemia can lead to the exacerbation of hyperglycemia and increase the complications of diabetes, and cardiovascular diseases are one of the most important complications of diabetes mellitus. Therefore, the aim of this study was to investigate the effect of 4 weeks of aerobic training on catalase enzyme activity in the left ventricle and insulin resistance index in male rats treated with streptozotocin and exposed to a high-fat diet.
Methods: In this experimental study, 19 male wistar rats, with an average age of 8-12 weeks and a weight of 200-250 grams, were divided into 3 groups: diabetic control (CD 8), training diabetes (TD 8) and healthy control (C 3). The exercise program included 4 weeks of aerobic exercise with an average of 60 to 75 Vo2max in an increasing manner. Before and 48 hours after the last training session, blood was taken and left ventricular tissue samples were extracted to check the HOMA-IR index and catalase activity by ELISA method. To compare the study groups, one-way analysis of variance and Scheffe's post hoc test were used in SPSS software (p≥0.05).
Results: The results showed that the induction of diabetes with STZ along with a high-fat diet causes a significant decrease in catalase enzyme (P=0.001) and a significant increase in HOMA-IR index, fasting glucose and Li index (P=0.001) in rats. However, doing 4 weeks of aerobic training caused a significant increase in catalase enzyme activity (P=0.001) and a decrease in HOMA-IR index, glucose and Li index (P=0.001).
Conclusion: Aerobic exercise with moderate intensity can be used as an effective non-pharmacological method in the treatment of diabetic cardiomyopathy by increasing catalase activity and reducing resistance to insulitis in diabetes.

Background: One of the complications of type 2 diabetes is the development of neurocognitive disorders, and DCX and AMPA may be involved in this disorder. Therefore, this study aimed to investigate the effect of aerobic exercise on the DCX and AMPA in the hippocampus of rats with type 2 diabetes.
Methods: 32 eight-week-old male rats were divided into control (C), diabetes (D), diabetes-exercise (DT), and exercise (T) groups. Diabetes was induced by streptozotocin injection. The exercise was carried out for six weeks. Finally, the rats were dissected, and their hippocampus tissue was extracted. Proteins were measured by the ELISA method.
Results: There was nonsignificant difference between the DCX of the C group and the T and DT groups (p>0.05). But there was a significant difference between the DCX of the C and diabetic groups (p =0.05). Also, a significant difference was observed between the diabetic groups and the T group (p<0.05). AMPA in diabetic groups were significantly lower than in C and T groups (p<0.05) While the difference between C and T groups and D and DT groups was not significant (p>0.05). Also, a significant negative correlation was observed between AMPA and DCX with blood glucose.
Conclusion: Diabetes reduces the AMPA and DCX but exercise nonsignificantly reduces the effect of diabetes on those. According to the appropriate duration of exercise, there is a possibility that due to the significant negative correlation between these proteins and glucose, the intensity of exercise can significantly reduce the negative effect of diabetes on those.

Background: The aim of the present study was to study the changes in the expression of Cox-1 and Cox-2 genes in liver tissue and tumor volume after aerobic exercise and consumption of pineapple extract in mice with skin cancer.
Methods: This fundamental-laboratory study was conducted on 32 male C57BL/6 mice in four groups including control, aerobic exercise, pineapple extract and aerobic-pineapple exercise. After tumor induction, the animals underwent aerobic training program for six weeks and pineapple extract was gavage at 300mg/kg. The weight and tumor volume of mice were measured. After obtaining blood and tissue samples, expression of Cox-1 and Cox-2 genes in liver tissue was done by RT-PCR method. Then the data were analyzed using one-way analysis of variance, two-factor analysis of variance and post hoc test, and the significance level of p≤0.05 was considered.
Results: Compared to the control group, aerobic exercise and pineapple-exercise showed a significant decrease in tumor volume and a decrease in the expression of Cox-1 (0.59±0.97) and Cox-2 (0.5±0.4) gene expression in the aerobic-Pineapple compared to the control group (1±0) (p≤0.05). Cox1 gene expression increased significantly in the Aerobic exercise group, but a significant decrease was observed in the pineapple-Aerobic group. Also, Cox2 gene expression in the liver tissue in the exercise group Aerobic and interactive Aerobic-pineapple group had a significant decrease compared to the control, but in the pineapple group compared to the control, the difference in the expression of this gene was not significant.
Conclusion: The results of the present study showed that the expression of Cox 1 gene was significantly increased in the aerobic training group and significantly decreased in the pineapple-training group. Cox-2 gene expression in the liver tissue in the aerobic training group and the pineapple-training interactive group had a significant decrease compared to the control, because the Cox-2 enzyme is related to inflammation and pain, angiogenesis, cancer and Alzheimer's disease. Therefore, it can be concluded that its inhibition or reduction can be considered as a promising and effective strategy for the treatment and prevention of cancer.

Background: The purpose of this study was to investigate the impact of aerobic exercise on the function of local renin-angiotensin system and insulin resistance in the Gastrocnemius muscle of type 2 diabetic mice.
Methods: The number of 18 male C57BL/6 mice were divided into two groups: 1. Mice fed with a standard diet for 12 weeks (control group), 2. Mice fed with a high-fat diet for 12 weeks with streptozotocin injection (diabetes group). Diabetic mice were randomly divided into two groups: 1. Diabetes-Sedentary group, 2. Diabetes-exercise group. The mice of the training group exercised on the treadmill for eight weeks and five days/week with an average speed of 19 m/min and for 45 minutes. 24 hours after the last training session, the mice were sacrificed. The Gastrocnemius muscle tissue was extracted and stored in -80°C freezer to measure the expression level of angiotensin 2, Mass receptor, At1 receptor and glucose transporter 4 (Glut 4).
Results: The results showed that the expression of Mass and Glut4 receptor in diabetes-exercise mice was significantly higher than diabetes-sedentary group. Also, the expression of angiotensin 2, HOMA-IR, and fasting glucose in the muscle of diabetes-exercise mice were significantly lower vs. diabetes-sedentary mice. Also, the expression of At1 receptor in the diabetes-exercise group was insignificantly lower than in the diabetes-sedentary group.
Conclusion: The findings of the present study show the important role of exercise in improving the local renin-angiotensin system in skeletal muscle. Eight weeks of aerobic training can reduce muscular insulin resistance and improve type 2 diabetes by decreasing the expression of angiotensin 2, At1 receptor and increasing the Mass receptor.

Background: Diabetes is a global epidemic and the most common metabolic disorder caused by impaired insulin secretion and glucose metabolism. The aim of this study was to investigate the effect of 8 weeks of aerobic training on serum levels of asprosin and insulin resistance index in diabetic rats.
Methods: The statistical population of this research included 40 10-week-old mice with an initial weight of 250 ± 20 grams, which were randomly divided into four groups (10 mice in each group): diabetic-exercise group (DT), diabetic group - Control (DC), healthy-training group (HT) and healthy-control group (HC) were divided. The program of aerobic exercises was performed for 8 weeks (5 sessions per week) in the form of running on a treadmill. Independent t-test and one-way analysis of variance (ANOVA) with Tukey's post hoc test were used to compare the groups. All data were analyzed at a significance level of 0.05 using SPSS-25 software.
Results: The results of the present study showed that streptozotocin injection induced diabetes in mice (P= 0.001). Induction of diabetes caused a significant increase in the serum levels of asprosin and insulin resistance in mice (P= 0.048 and P= 0.012, respectively). Eight weeks of aerobic training decreased the serum levels of asprosin and decreased insulin resistance in diabetic rats (P= 0.001 and P= 0.036, respectively).
Conclusion: Induced diabetes causes insulin resistance and increase in serum levels of asprosine, which can be improved by performing aerobic exercises.
