Background and Aim: attention-deficit/hyperactivity disorder or ADHD is one of the most common problems of children and adolescents and the reason for referral to psychiatrists and psychologists. Therefore, the aim of this research was to the effectiveness of parent-child interaction training on behavioural problems and aggression of children with ADHD symptoms. Methods: In terms of the purpose, the current research design was of an applied type and in terms of the method of conducting it, it was a quasi-experimental research with a pre-test, post-test and two-month follow-up plan with the experimental and control groups. The statistical population of this study consisted of 6-10-year-old children with ADHD who were referred to a private counselling centre in the 10th district of Tehran in 1401. An available sampling method was used for sampling, and 30 people were selected, and 15 people were equally assigned to the experimental group and 15 people to the control group. In this research, the tools used included Achenbach's Child Behavior Checklist (CBCL), and Buss & Perry's (1992) Aggression Questionnaire. Parent-child interaction therapy was performed according to McNeil & Hembree-Kigin's (2010) protocol on the experimental group, but the control group did not receive any intervention. Statistical data was analyzed with spss software and using analysis of variance with repeated measurements, and Bonferroni's post hoc test was used to check the stability of the effects of the interventions. Results: F values were calculated for behavioural problems (F = 7.63) and aggression (F = 10.74). It can be concluded that the effect of the group membership factor, or in other words, the treatment of parent-child interaction, has led to a significant decrease in dependent variables (p<0.01). The results of Benferroni's post hoc test indicate that the effect of parent-child interaction therapy on behavioural problems and aggression of children with ADHD was stable. Conclusion: It can be concluded that parent-child interaction training was effective on behavioural problems and aggression of children with ADHD symptoms, and this effect was stable.

Background: Physical activity affects the health of the body's organs through several processes. Apoptosis is one of the important cellular processes that play a role in maintaining the balance between cell death and tissue growth. Aim: The aim of the present study was to examine the previous findings regarding the effect of physical activity and exercise on apoptosis in order to obtain a relatively comprehensive knowledge of this effect by summarizing and analyzing the data. Materials and Methods: To collect the information of the articles, a search was made from PubMed, MEDLINE, SID, IranMedex, IranDoc, Magiran and Medlib databases. More than 80 scientific articles from 2000 to 2023 were reviewed. The keywords used were: physical activity, aerobic exercise, endurance exercise, apoptosis and cell suicide. After the review, finally 26 articles were selected. Then, the selected items were fully studied and finalized, and the items that were more complete than the others were selected as references. Conclusion: Physical activity and exercise, especially aerobic exercise, as a safe, cheap and accessible method, can reduce apoptosis through several mechanisms. The breadth of studies in this field, and the overlapping of many data, allows us to confidently introduce exercise and aerobic activity as one of the best methods of regulating body homeostasis and reducing apoptosis.

Purpose: Type 2 diabetes is one of the most important metabolic disorders that different societies are facing with increasing prevalence. Aerobic exercises are a common type of exercise that reduces the levels of triglycerides and low-density lipoproteins and regulates blood pressure. The purpose of the research is to investigate the effect of 12 weeks of aerobic exercise on fasting glucose and several serum indicators of cardiovascular disease, in women with type 2 diabetes. Methods: In 2023, 20 women who referred to the Hamadan Diabetes Association voluntarily participated as subjects in this research and were randomly assigned to aerobic (10 people) and control (10 people) groups. The exercise program of the aerobic group included 3 running sessions per week with an intensity of 60-70% of the maximum heart rate for 12 weeks. In order to measure fasting blood glucose, glycosylated hemoglobin (HbA1c) and lipid profile [low-density lipoprotein (LDL-c), triglycerides (TG), High-density lipoprotein (HDL-c)], blood sampling was done before and after 12 weeks of exercise program. SPSS software and Kologrov Smirnov and Student's t test were used to check and analyze the data. Results: The results indicated that after 12 weeks of aerobic exercise, HbA1c (P=0/027), LDL-c (P=0/012) and fasting blood glucose (P=0/043) decreased significantly in the aerobic group. But no significant changes were observed in HDL-c and BMI. Conclusion: The results of this research showed that performing aerobic exercises leads to a decrease in HbA1c, fasting blood glucose and improvement in lipid profile, so it can probably be a useful way of treatment and prevention of cardiovascular diseases in type 2 diabetic patients.
