Abstract
The present study aimed to evaluate pragmatic skill of adult right and left hemispheres damaged Persian speaking patients using the Persian version of the Montreal Protocol for the Evaluation of Communication (M.E.C.). The statistical populations of the study were 10 adults, right and left hemispheres damaged Persian speaking patients due to cerebrovascular accident (CVA). Two sets of tests were used in the present study. The first ones were screening tests included Lateral Preference Inventory (Corn test), Mini Mental State Examination (MMSE) and Persian Diagnostic Aphasia Battery (EQ1). The Performance of patients in protocol subtests were evaluated and compared with each other individually, intragroup and intergroup. Data were analyzed using inferential statistical methods and no meaningful relations were found between them. These findings indicated that damage to the right and left hemispheres of the brain leads to pragmatic impairments. However, damages to the right hemisphere increases the severity of pragmatic impairments more than damages to the left hemisphere.

Abstract
Aims: Smokers are exposed to significant quantities of oxidative factors. The exercise has been shown to increase activation of antioxidant enzymes and reduce the production of free radicals in the body. Therefore, the present study was investigated the effect of 12 weeks of combined training on oxidative stress and antioxidants capacity in smoker's football players.
Materials & Methods: 22 smoker's football players with normal weight and the average age of 23.9±1.9 years were randomly divided into two experimental and control groups. The experimental group submitted to combine training including aerobic and resistance exercise (3 sessions per week) for 12 weeks. Antioxidant indicators (catalase and superoxide dismutase) and lipid peroxidation indicator (malondialdehyde) were measured 48 hours before and after protocol at least 8 hours of fasting. Dependent t-test was used to investigate the differences within the group data, and independent t-test was applied to investigate intergroup differences. The significance level was p≤0.05.
Findings: 12 weeks of combined training (aerobic and resistance) was caused respectively significant increase and decrease amounts of enzymes CAT and SOD as antioxidant indicators and MDA as lipid peroxidation indicators in smoker's football players (p≤0.05).
Conclusion: Combined exercise training (aerobic and resistance) likely by increase antioxidant capacity and decrease lipid peroxidation indicators eliminates the oxidative stress in smoker's football players.

Abstract
Introduction: endurance and resistance exercise and the consumption of hawthorn alone and in combination have an effect on Alzheimer's disease.This study was conducted with the aim of the effect of hawthorn consumption and exercise on the inflammatory indices of Alzheimer's rats by trimethyltin chloride (TMT).
Materials and methods: rats were randomly divided into 9 healthy control and Alzheimer's groups with interventions (control, endurance training, resistance training, combined training, hawthorn, endurance training + hawthorn, resistance training + hawthorn, combined training + hawthorn). Then Alzheimer's disease developed. performed resistance , combined ,endurance exercises every week (12 weeks). Finally, blood was taken from the inferior vena and the inflammatory variables CRP, IL-6 ,TNF-α were measured by ELISA method. The Shapiro-Wilk test was used to check the normal distribution of the data, and the one-way analysis of variance (ANOVA) was used to check the mean difference between the groups (Tukey's test). P <0.05 were considered statistically significant.
Results: results showed that the induction of Alzheimer's disease induced by TMT caused a significant increase in the levels of TNF α, IL 6, CRP in the Alzheimer's control group compared to the healthy control. And 12 weeks of combined training with and without hawthorn had a significant decrease in the level of these variables compared to Alzheimer's control.
Conclusion: As a result, endurance and resistance sports along with the consumption of hawthorn lead to the reduction of some inflammatory factors in Alzheimer's rats.

Abstract
Introduction: Ferritin is an indicator of iron (Fe) storage in the body and plays the main role of cellular oxidation. It is hypothesized that Fe causes insulin resistance and then by reducing insulin secretion leads to type 2 diabetes. Considering the effects of exercise training in increasing insulin sensitivity, this study was designed the effect of various resistance (DR), endurance (DE), and combined (DER) activities on serum ferritin and Fe levels in diabetic rats. Materials and methods: Type 2 diabetes was induced by intraperitoneal injection of Nicotinamide solution (120 mg/kg) and Streptozotocin (65 mg/kg). One week after the confirmation of diabetes, the training groups underwent DR, DE and DER exercises for 10 weeks. After completing the research protocol, blood sampling was done to measure serum ferritin and Fe levels. Results: Type 2 diabetes caused an adverse increase in blood glucose, insulin levels, increased HOMA-IR, Fe, serum ferritin and decreased HOMA-IS. Looking to improve glycemic indices after 10 weeks of DE, DR and DER training, we saw a decrease in serum Fe and ferritin levels, and DER training had a significant decrease in Fe compared to DR and DE training. Conclusion: This study shows that serum iron and ferritin levels in diabetes are significantly increased and increased ferritin may be one of the reasons for insulin resistance in diabetes. Given the importance of iron and ferritin levels in insulin resistance, combined exercise with moderate intensity and time by reducing these biomarkers can reduce glycemic indices in diabetes.
