Abstract
Background and Aim: Despite numerous advances in treating various diseases and increased life expectancy, obesity will be the leading cause of hopelessness in the next 100 years. The present study aimed to compare the effects of Acceptance and Commitment Therapy (ACT) and Cognitive-Behavioral Therapy (CBT) on lifestyle habits, disordered eating behavior, and health-promoting lifestyle in obese women.
Methods & Materials: The statistical population consisted of all women referring to obesity clinics in district 2 of Tehran City, Iran, in 2019. Forty-Five patients were selected by convenience sampling method and replaced in 3 groups of 15 (two experimental & one control groups). The study participants were assessed using the Assessment of Life Habits Scale (LIFE-H)), the Eating Attitudes Test (EAT), and the Health Promoting Lifestyle Profile-II (HPLP-II). The ACT group underwent nine 90-minute sessions and the CBT group received eight 90-minute sessions. The control group received no training. The collected data were analyzed using Mixed Design and repeated-measures Analysis of Variance (ANOVA) in SPSS.
Ethical Considerations This study was approved by the Research Ethics Committee of Islamic Azad University, Karaj Branch (Code: IR.IAU.K.REC.1398.039).
Results: The present research results signified that ACT and CBT were effective on the habits of eating disorders and health-promoting lifestyles in the explored obese women. The achieved changes remained stable until the follow-up phase (P<0.001). Moreover, ACT was more successful than CBT in improving the components of life habits and health responsibilities in the study subjects (P<0.001).
Conclusion: Considering the significant effect of group-based ACT and CBT, it is recommended to use these methods to increase the mental health of obese individuals.

Abstract
Introduction: Methamphetamine increases the release of dopamine from nerve terminals. Binding of dopamine to dopamine receptors increases the phosphorylation of cyclic adenosine monophosphate responsive element (CREB) protein and changes the transcription of downstream genes.The purpose of this study is to investigate the effect of methamphetamine induction followed by aerobic training and Berberine on dopamine receptor 4 and CREB gene expression in the heart tissue of methamphetamine-addicted female rats during the withdrawal period.
Methods: 30 rats were randomly divided into 5 control groups, methamphetamine, methamphetamine + aerobic training, methamphetamine + Berberine, methamphetamine + aerobic training + Berberine. Intraperitoneal injection of 10 mg/kg of methamphetamine was performed for 5 days, and during the withdrawal period, aerobic training was performed for 4 weeks and simultaneously the consumption of berberine 100 mg/kg as a solution in drinking water was considered. Real Time PCR method was used to measure gene expression. Independent T-test, Kruskal-Wallis test and SPSS24 software were used at the level of 0.05 to analyze the data. The code of ethics in the research was received with number IR.IAU.SHAHROOD.REC.1402.015.
Results: The results showed that methamphetamine use caused a non-significant increase (97%) in CREB expression and a non-significant decrease (52%) in dopamine 4 receptor compared to the control group (P>0.05). The implementation of interventions during the withdrawal period, such as Berberine consumption and the combination of berberine with aerobic training, produced non-significant increasing and decreasing effects on dopamine 4 receptor gene expression and CREB in the heart of methamphetamine-addicted rats, respectively (P > 0.05).
Conclusions: Short-term induction of methamphetamine did not cause significant changes in the expression of dopamine 4 receptor and CREB genes in the heart. Therefore, these genes could not undergo a significant change as a result of interventions such as Berberine and exercise. More studies are needed to investigate exact genetic changes in heart tissue.
