Abstract
Background and Aim Old age is a critical period in life. Due to advances in technologies and improvement in healthy conditions, the number of aged population is increasing. Hence, it is necessary to pay attention to their life satisfaction and attitudes towards aging. The present study aims to assess the effectiveness of a psychological empowerment program on life satisfaction and attitude towards aging in older women living in Tehran, Iran.
Methods & Materials The study population consists of all women aged 60-70 years referred to a charity foundation in Tehran, Iran in 2020. Of these, 24 women were selected by a convenience sampling method. They were randomly assigned to the intervention (n=12) and control (n=12) groups. Using a pre-test/post-test design, the elderly first completed the life satisfaction index-Z and the attitude towards aging questionnaire. Then, the experimental group received the psychological empowerment program at 8 sessions. After the intervention, the questionnaires were completed again by both groups. Multivariate analysis of covariance was used to analyze the collected data in SPSS software, version 19.
Ethical Considerations This study was approved by the Research Ethics Committee of Islamic Azad University of Arak Branch (Code: IR.IAU.ARAK.REC.1400.027).
Results There was a significant difference in life satisfaction (F=9.673, P=0.006) and attitudes towards aging (F=8.385, P=0.009) between the two groups. The psychological empowerment program significantly improved life satisfaction and attitudes towards aging in older women.
Conclusion The psychological empowerment program is effective in improving life satisfaction and attitude towards aging in older women living in Tehran. It can be used by experts in the fields of counseling, geriatrics, psychology, and health.

Abstract
Background and Aim The internationalization of higher education is an effective strategy to meet the diverse needs of a society. One of the factors determining the failure or success of internationalization is the organizational culture of universities. The present study aims to investigate the role of organizational culture-related factors in the internationalization of Iranian universities.
Methods & Materials This is a quantitative-quantitative study. Participants were 124 Iranian experts in higher education and those involved in internationalization of universities. A researcher-made questionnaire was used as a self-report tool with close-ended questions. In the quantitative stage, structural equation modeling and first- and second-order factor analysis were performed in SPSS and AMOS software.
Ethical Considerations This study was approved by the ethics committee of Islamic Azad University, Rasht Branch (Code: IR.IAU.RASHT.REC.1400.035)
Results The ranking of factors affecting the internationalization of Iranian universities showed that the factor with the highest factor loading was “communication & interaction” (1.03) and the factor with the lowest factor loading was “human/physical/financial resources” (0.87).
Conclusion Communication/interaction of universities with other education centers, as an organizational culture-related factor, plays an important role in the internationalization of Iranian universities.

Abstract
Introduction: The beneficial effects of physical activity in the treatment of brain-motor disorders of people with autism have received more attention, although the effects of exercise on the evaluation of motor factors (physical fitness) and brain waves have been less studied.
Methods: Eleven children with autism spectrum disorder (7-12 years) took part in the study. After a thorough medical examination and psychiatric assessment, children participated in aquatic exercise program (twice-weekly) for 8 consecutive weeks. Pre & post intervention evaluated base on QEEG (power alpha & coherence), movement assessment (euro fit exam), then stoical analyze are performed (P<0.05). The present research has been registered with the ethics committee of the faculty of sport sciences, Bu-Ali Sina University Hamadan under code IR.UMSHA.REC.1394.107.
Results: In this study, alpha wave absolute power but not coherence in frontal – occipital is significantly increased by8 consecutive weeks’ aquatic program (P<0.05). Physical Fitness assessment parameters (muscular strength/endurance, coordination, balance, flexibility) significantly improved and subside respectively (P<0.05).
Conclusions: These results indicate that aquatic exercise program may improve physical and mental disturbance in young children with autism spectrum disorder.

Abstract
Introduction: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in industrialized societies. As an appetite inhibitory and energy balance regulator, nesfatin-1 plays a substantial role in the pathogenesis of obesity-related abnormalities. This study was conducted to determine the effects of 12 weeks of combined training (resistance training and high-intensity interval training (HIIT)) on the serum levels of nesfatin-1 and some liver enzymes in men with NAFLD.
Methods: In this semi-experimental study, 20 middle-aged men with NAFLD were randomly divided into two exercise and control groups. The exercise program included 12 weeks of combined training, featuring two sessions per week of resistance training and one session of HIIT. Body weight, body mass index (BMI), nesfatin-1 peptide, liver enzymes (ALT, AST, and ALP), lipid profile, maximal oxygen consumption (VO2max), and body fat percentage at the beginning and after 12-weeks were evaluated. Independent and dependent t-tests were analyzed to assess intra-group and inter-group differences, and the significance level was
P < 0.05.
Results: 12 weeks of combined resistance training and HIIT increased nesfatin-1 and decreased liver enzymes ALT, AST, and ALP in the exercise group compared to the control group and the pre-training stage (P < 0.05). We also observed an increase in VO2 max and a decrease in body weight, BMI, body fat percentage, and LDL in the exercise group compared to before starting the training protocol (P < 0.05).
Conclusions: Based on the results of the present study, it can be concluded that performing combined exercise training for twelve weeks led to an increase in nesfatin-1 peptide levels and a decrease in liver enzymes. It was suggested that this could be a cost-effective therapeutic approach recommended for patients with NAFLD.

Abstract
Introduction: The thickness of the molecular and pyramidal layers in the hippocampus represents a pivotal aspect of Alzheimer's research. This study was conducted to investigate the effect of swimming endurance, resistance, and combined exercises on the molecular and pyramidal layers of the hippocampus tissue thickness of Alzheimer's rats.
Methods: In this experimental study, 40 large white Wistar laboratory rats (6 weeks old; Weight 180-200 g) were randomly and equally divided into five groups: healthy control, Alzheimer's control, endurance, resistance, and combined. Alzheimer's disease was induced by intraperitoneal injection of trimethyltin chloride (8 mg/kg). Two weeks after the injection and confirmation of Alzheimer's induction, the training protocols of endurance (5-sessions/week, the first to the fourth week incrementally from 5-15-min to 45-min of swimming, the fifth to the twelfth week 60-min of swimming), resistance (5-sessions/week, The first week of familiarization with the exercise, week 2; 30%, week3-5; 70-90%, week6-8; 100-110%, week9-10; 120-130%, and week11-12; 140-150% of body weight), combined (2 resistance sessions/week and three endurance sessions/week) was performed for 12 weeks. Forty-eight hours post-intervention, animals were dissected, and hippocampus tissue was harvested. Finally, the data were analyzed at the significance level of P < 0.05.
Results: The thickness of the molecular and pyramidal layers of the hippocampal tissue of Alzheimer's animals decreased compared to healthy animals, and all three endurance, resistance, and combined exercise protocols increased layers (P < 0.001). However, the increase in the molecular and pyramidal layers thickness of the hippocampal tissue of combined group rats compared to the endurance and resistance group had a greater increase (P < 0.01).
Conclusions: These findings highlight the changes in the thickness of the hippocampal tissue layers concerning Alzheimer's pathology and the effect of combined exercises on this parameter. While exercise may have positively affected hippocampal volume and synaptic plasticity, more research is needed to fully understand the impact of exercise on hippocampal layer thickness in Alzheimer's.

Abstract
Introduction: Being overweight is associated with increased cortisol secretion, along with heightened anxiety and depression. This study aimed to compare the effect of six weeks of concurrent moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) with HIIT training alone on body composition, plasma cortisol levels, and anxiety and depression levels in overweight male students.
Methods: In this semi-experimental research, 27 overweight students were selected and randomly divided into three groups 9: MICT+HIIT concurrent training, HIIT training, and a control group. The MICT )15 minutes of exercise per day at 60-65% of maximum heart rate with an additional 5 minutes every two weeks). The HIIT (3 minutes of running at 70-75% of maximum heart rate, followed by 3 minutes of active rest at 50% of maximum heart rate, with three repetitions in the first two weeks, four repetitions in the second two weeks, and five repetitions in the final two weeks).
Results: Both types of training protocols resulted in reductions in weight, body mass index, cholesterol, low-density lipoprotein, cortisol levels, anxiety, depression, and an increase in high-density lipoprotein (P < 0.05). There was no significant difference between the two types of exercise in terms of effectiveness on these variables; however, only peak oxygen consumption and triglycerides were associated with better changes in the MICT+HIIT group.
Conclusions: For overweight male adolescents aiming for weight loss and improved mental health, HIIT alone is sufficient, and adding MICT does not provide additional clinical benefits.
