Abbas Saremi

Introduction: Physical activity is one of the important lifestyle factors that can have positive or negative effects on the reproductive system, and more research is needed to reflect the effect of inactivity on fertility in order to provide safe lifestyle recommendations to help couples achieve pregnancy is required. Therefore, this study was conducted with the aim of describing and comparing the physical activity status of fertile and infertile men in Arak city in 2022.
Methods: The present study is a case-control study that was conducted on 220 fertile and infertile men (22 to 40 years old) referred to Arak University Jihad infertility centers that were selected through available sampling. Participants completed self-test questionnaires on socio-demographic characteristics, lifestyle, physical activity, and sedentary behaviors. Anthropometric characteristics and body composition were also measured. Multivariate logistic regression was used to analyze the association of infertility with physical activity level, sedentary behavior, and body composition.
Ethical Considerations: This study was approved by the Ethics Committee of the University of Arak University (Code: IR.ARAKMU.REC.1401.046).
Ethical Considerations: The present research has been registered with the code IR.ARAKU.REC.1401.015 in the Ethics Committee of Arak University.
Results: In this study, it was observed that the amount of physical activity (P=0.02) and body composition (P=0.001) in fertile men is more favorable than infertile men. In men with a low level of physical activity, the risk of infertility increases 2.97 times (odds ratio 2.97 and 95% CI: 1.03, 8.61, and P=0.04). On the other hand, in men with moderate level of physical activity, the risk of infertility decreases (odds ratio 0.27 and 95% CI: 0.08, 0.92, and P=0.03). Also, in men who sit for more than 6 hours a day, the chance of infertility increases by 3.02 times (odds ratio 3.02 and 95% CI: 1.28, 7.10, and P=0.01). An increase in body mass index increases the risk of infertility by 1.61 times in men (odds ratio 1.61 and 95% CI: 1.23 and 2.11 and P=0.001).
Conclusions: Since obesity, physical inactivity and infertility in Iranian men are increasing at the same time, so there should be more focus and seriousness on the issue of lifestyle modification and especially physical activity regarding reproductive health.

Introduction: Since a more appropriate psychological treatment has not yet been found in the treatment of autism to be a definite solution in autism, in this research, two more common psychological methods have been compared. Objectives The aims of this study were to compare the effectiveness of ABA and Fluortime play therapy on sensory processing in children with autism spectrum disorder in Qom in 1401.
Methods: The method of this quasi-experimental study was pre-test-post-test and follow-up with a control group. The statistical population of the research included all the children with autism in land Qom at Golhay Behesht Autism Center. The statistical sample of this research was 45 people who were selected by available sampling, and randomly divided into three experimental groups using the ABA method (15 people Fluortime method (15 people) and the control group (15 people) were placed. The first experimental group was treated with the method of ABA in the designated sessions. 23 20-minute sessions were presented to the subject group. During experimental group Fluortime was treated with the method of 23 sessions of 20 minutes, it was presented to the subject group, then it was analyzed using analysis of variance with repeated measurements. Ethical Considerations: This article is approved by the ethics committee of Islamic Azad University Ahvaz branch IR.IAU.AHVAZ.REC.1401.032.
Results: The results of the analysis showed that the Flortime play therapy training in sensory processing was significantly at the level of the effect of the implementation of independent variables on the registration components down (P = 0.02) Sensory seeking (P = 0.001) Sensory sensitivity (P = 0.019) Sensory avoidance (P = 0.004) is significant. On the other hand, the average difference of sensory processing components in the applied behavior analysis and game group is significant. Fluortime treatment is significant with the control group. So that the mean of the components of sensory processing in both experimental groups has a significant0.05 ≥ P decrease compared to the control group.
Conclusions: This finding, in line with the change trend of the mean of the components of sensory processing, shows that functional ABA and Fluortime play therapy during the implementation period. And three months after the completion of the implementation period, it has led to a significant decrease in the average scores of sensory processing components. Sensory processing in children with autism spectrum disorder. It should be mentioned that in comparison, the scores of sensory seeking, sensory sensitivity and sensory avoidance in the Fluortime were higher than in the ABA method, and low registration was higher in the ABA method, but the results of the Ben Feroni test show that although each method was significant separately in sensory processing, the difference in effect Functional behavior analysis and Fluortime play therapy on sensory processing components of p>0/05 is not significant.

The Protective Effect of Resistance Training on Kidney Tissue and Changes in Serum Levels of Oxidant and Antioxidant Factors in Rats Exposed to X-ray Irradiation

Mohammad parastesh

Introduction: In recent years, the use of X-rays in medicine and industry has expanded significantly. X-rays can cause oxidative stress and subsequently induce destructive effects on the kidneys. On the other hand, it has been proven that according to the theory of hormesis, resistance exercises have antioxidant effects, which may be used to reduce the harmful effects of X-rays. This study investigated the effect of resistance training on oxidative stress factors and structural changes in kidney tissue in rats exposed to X-rays
Methods: Twenty-four male rats were randomly divided into 4 groups. The irradiated groups were exposed to 4Gy X-ray. The training groups were exercised 5 times per week for 10 weeks. 24 hours after the last training session, blood samples were collected for evaluation of oxidative and antioxidant factors, and kidney tissue was isolated for stereological studies. The data was analyzed by one-way ANOVA in SPSS 20 software.
Results: In this study, whole-body X-ray irradiation caused a significant increase in kidney volume (P=0.003), cortex volume (P=0.02), glomerular volume (P=0.039), and serum Malondialdehyde (MDA) level (P=0.03). Also, performing the training protocol significantly reduced kidney volume (P=0.03), cortex volume (P=0.04), glomerular volume (P=0.033), and serum MDA level (P=0.02).
Conclusions: Based on this research, it seems that resistance training can lead to a decrease in glomerular filtration by creating adaptation and increasing antioxidant defense and changes in the hemodynamics of the kidneys, and as a result, reducing the volume and number of glomeruli, reducing the volume of the cortex and kidney, and it can improve the structure of kidney tissue in rats exposed to X-ray radiation.
