Introduction: Even today there is no effective drug therapy to prevent neuronal loss after brain stroke. In the present study we studied the effect of mitochondrial KATP channel regulators on neuronal ultrastructure after ischemia reperfusion in the rat. Materials & Methods: Rats temporarily subjected to four vessels occlusion for 15 minutes followed by 24 hours reperfusion with or without K-ATP channel regulators.
Results: Neuronal ultrastructure significantly improved in K-ATP channel opener (diazoxide) treated ischemia-reperfusion group compared with control group.
Discussion: Our results showed that dizoxide treatment after ischemia reperfusion leads to better preservation of cortical neurons in rat.

Abstract
Introduction: Coping responses are complex dynamic behavioral reactions that involve reciprocal influences between emotion and cognition but cognitive studies in Iran have less emphasized coping responses of methamphetamine dependent individuals to distressing situations. To address this aim, the current study was designed to investigate the coping responses of a group of methamphetamine dependent women in comparison with a group of healthy women.
Methods:
80 women with mean age 24(SD=6.8) years who met DSM.IV-TR criteria for methamphetamine dependence were recruited from the department of psychostimulant use treatment program of Rojan psychiatric center and 4 other local clinics in Tehran, Iran and were matched with a sample of 80 non-drug taking women. First, demographics and details of substance use were completed based on items elicited from Addiction Severity Index (ASI), then the Persian version of Billings and Moos Coping Checklist was completed by participants in each group. Data was further analyzed by performing independent sample t-test and logistic regression model in SPSS.v.16.0. Results:
The study findings indicated that the methamphetamine dependent group applied less problem-solving response and had lower reliance on seeking social support and cognitive evaluation compared with the controls. In addition, the methamphetamine dependent group applied significantly more emotional and physical control oriented responses compared with the controls. Discussion:
The study results yielded that coping responses of the methamphetamine dependent group were less problem-focused strategies which show an impaired aspect of cognitive functioning which is subject to clinical and treatment implications. Study in the context of identifying aspects that are fundamental to understanding the neural mechanisms underlying emotion-cognition interactions in the paradigm of coping responses is discussed.

Abstract
Introduction: Risk-taking has an important role in human life, either positive or negative. Finding a method to control or drive this in a particular way can affect the health of individuals and communities by discouraging negative risks, such as reckless driving, or encouraging positive risks. It has been shown that emotion induction can enhance risk-taking behavior. Nonetheless, studies are mainly conducted on adults and a gap to focus on adolescents group as the peak age of risk-taking is required. Therefore, a new risk-taking task is introduced and development of risk-taking behavior in children is compared with a group male adults. In addition, influence of positive and negative emotional images on the risk-taking behavior is also evaluated.
Methods: A total of 21 children and 20 adults participated in this experiment. Their risk taking behavior is obtained using a new version of the dice game task with emotional stimuli. Subsequently, performances of two groups before and after emotional priming are statistically compared.
Results: The results showed that children have a higher tendency to choose riskier options when they are affected by positive emotion, while adults are more risk-averse after being primed by negative emotion.
Conclusion: These findings can be helpful for policymakers and tutoring planners to control risk-taking behavior at different ages using the priming effect of positive and negative emotions.

Abstract
Introduction: Evidence indicates that medial septum nicotinic receptors regulate cognitive processes. Ghrelin is a gut hormone that regulates energy homeostasis. Ghrelin is also produced in the brain and is involved in cognitive function. This study aims to evaluate the effects of medial septal administration of ghrelin on the amnestic effect of morphine in rats.In addition, the possible relationship between the medial septal ghrelin and acetylcholine nicotinic receptors on the amnestic effect of morphine is evaluated.
Methods: The rats were implanted at the medial septum area and were microinjected with ghrelin and nicotinic receptor agents. The step-through type inhibitory avoidance apparatus was used for memory retrieval assessment.
Results: The results showed that the administration of morphine after the training phase impaired memory consolidation. Post-training intra-septal injection of the same doses of either ghrelin or nicotine did not change memory performance; however, their co-application with morphine (significant dose: 7.5 mg/kg subcutaneous injection) increased the step-through latency and improved memory consolidation. Moreover, post-training co-application of low doses of the two agonists could not affect morphine-induced memory impairment.
Conclusion: These results indicated no interaction between medial septal ghrelin and nicotinic receptors on the amnestic effect of morphine in rats.

Abstract
Introduction: According to the review studies, the growing knowledge of craving and the relevant causal factors that have led to the accumulation of solid theoretical frameworks over the past few years make it necessary to carry out a bibliometric review of this literature.
Methods: In this study, by examining the papers published during the last decade in the Scopus database, the largest citation database functional in mapping and content analysis of citation data, the researchers tried to clarify the research direction in the coming years.
Results: In craving research, multi-authored articles, such as Boswell’s (2016) study, garnered the highest number of citations. Boswell (2016) and Wolff (2016) have emerged as prominent figures in this field. Li X and the journal of addictive behaviors are leading producers of research in the craving domain. The highest volume of scientific output originates from the Department of Psychiatry, Yale University School of Medicine, with significant contributions from the United States, China, Germany, Italy, and England. The term “craving” exhibits the highest frequency of use. The co-authorship network illustrates that the most significant collaborations occur between the United States and other countries, where the majority of scientific output in this field is concentrated.
Conclusion: This analysis leads to the conclusion that studies about cravings occupy a prominent position in global etiological research and therapeutic interventions for addictive disorders. The enduring popularity of authors and publications addressing these disorders remains noteworthy.
