There is a close relationship between sleep behavior and service quality in nurses. Since nurses are one of the most important active groups in order to ensure the health of patients, they should have a good sleeping status. The present study was conducted with the aim of investigating the role of spiritual belief and emotion regulation in predicting insomnia problems in nursing personnel.

The research method was descriptive and correlational. The statistical population of the research included all the nurses working in the corona departments of the hospitals of Shiraz city in 2022, out of whom 150 were selected by available sampling method. Data collection was done using Insomnia Severity Index (Morin, 1993), Religious Orientation Scale (Allport & Ross, 1967), and Emotion Regulation Questionnaire (Gross & John, 2003). For data analysis, Pearson's correlation test and step-by-step regression were performed with SPSS statistical software version 26. Significance level was considered to be 0.05.

The results showed that there is a negative and significant relationship between emotion regulation and insomnia (r=-0.62 & p<0.05), and there is a negative and significant relationship between spiritual belief and insomnia (r=-0.56 & p<0.05). The regression results also indicated that predictive variables could simultaneously predict 31% of the variance in insomnia problems (R2=0.31 & P<0.007).

Based on the results of this research, increasing emotional management and spiritual belief are important factors in improving the sleep status of the nursing personnel.

Worldwide, aggression is one of the main death causes for people between the ages of 15 to 44. Understanding the risk factors may be critical to accurate aggression and treatment.

This study aimed to examine the relation between early traumatic events, callous-unemotional traits and insecure attachment style with aggression in a sample of adolescent out-patient.

Asample of high school students (n=345) with a mean age of 16.62 (SD=0.81) years completed Boss and Perry Aggression Questionnaire (BPAQ), Early Trauma Inventory (ETI), Inventory of Callous-Unemotional (ICU) traits and revised adult attachment scale (RAAS). The obtained data were analyzed using Pearson correlation coefficient and multivariate regression analysis.

Regression analysis revealed that 13% variance of aggression can be predicted by early traumatic events, insecure style of attachment and callous-unemotional traits.

Our findings provide further insight into the role of particularpsychopathy traits, trauma and attachment in developing and maintaining aggression. Study implications and limitations are considered.

Atherosclerosis is a chronic vascular disease and remains the leading cause of death and morbidity worldwide. Endothelial dysfunction is an important factor in the progression of atherosclerotic disease. Increased expression of cell adhesion index genes and decreased cell-binding proteins lead to abnormal endothelial function. These molecular changes are one of the most important indicators of endothelial cell dysfunction and the progression of atherosclerosis. CXCR3 is a G-protein-coupled chemokine receptor expressed by endothelial cells. The role of the receptor CXCR3 and its ligands in endothelial cells and heart disease is not yet fully understood. In this study, we evaluated the effect of CXCR3 downregulation on the expression level of adhesion (I-CAM-1, V-CAM-1), tight junction (TJP1), related to endothelial dysfunction.In order to reduce the expression of the CXCR3 gene, the RNA-cleaving DNAzyme was used against the mRNA of the CXCR3 gene. DNAzyme was transfused into HUVEC cells by TurboFectTM. After confirmation of decreased CXCR3 gene expression, RNA extraction and cDNA synthesis were performed and then the expression of markers was evaluated by RT-qPCR technique.Our result was showed the expression level of I-CAM-1 and V-CAM-1 were showed significant up-regulation in transfected cells compared with control cells, while the TJP1 gene was not showed significant change. It seems that reducing the CXCR3 gene expression could induce endothelial dysfunction through the change of adhesion markers genes expression. Therefore, this receptor can be considered as a potential molecular target for a better understanding of the mechanism of atherosclerosis.

Research evidence shows that exercise is associated with positive physical and mental health. Moreover, exercise and wheel running in rats activate overlapping neural systems and reward system. The most commonly used models for the study of rewarding and aversive effects of exercise involve using treadmill and wheel running paradigms in mice or rats. The purpose of our experiment was to study the influence of continuous voluntary exercise on exercise-seeking behavior.
In this experimental study, we used 24 adult male Sprague–Dawley rats weighing 275–300 g on average. Rats were divided into 3 experimental groups for 4 weeks of voluntary wheel running. Each rat ran in the cage equipped with a wheel during 24 hours. A within-subject repeated measure design was employed to evaluate the trend of running and running rates.
We found that time and higher levels of exercise will increase exercise tendency. Our results also show that the interaction of exercise within 4 weeks and different levels of exercise can significantly promote rats’ exercise-seeking behavior (F = 5.440; df = 2.08; P Our data suggest that voluntary wheel running can increase the likelihood of extreme and obsessive exercising which is a form of non-drug addiction.

Borderline personality (BP) is a serious mental condition in clinical practice which is marked by aggression and is shown to be affected by traumatic life events.
This study aimed to determine the relationship between early trauma and aggressive traits as predictive factors of borderline personality features (BPF) in high school students.
Three hundred and eleven students with mean age of 16.66 were recruited via multi stage random sampling. All the participants were asked to complete borderline personality features scale for children, early trauma inventory, and buss-perry aggression questionnaire. Analyzing data was done using canonical correlation.
The results indicated that BPF is predicted by early trauma and aggression traits.
In general, the findings showed that early trauma, physical aggression, verbal aggression, anger, and hostility can predict BPF and explain a considerable variance of survival index.

Addiction is described as a condition in which individuals are not able to control their drug use despite long-term negative consequences. Non-drug addiction or behavioral addiction such as exercise can mimic similar physiological changes in the brain and reward circuit enhancement. Psychological dependence of drug abuse, which is characterized by drug seeking behaviors will develop an ongoing cycle of drug withdrawal and relapse. Moreover, exercise has two bimodal effects; it may decrease drug seeking in a physiologic range and it may increase drug seeking when it is taken in large quantity. The current study aimed to investigate and compare the effects of voluntary and compulsory exercise on male rats’ tendency towards using morphine..
We included 32 male rats that were 2 months of age. After 2-weeks of compulsory and voluntary exercise, all rats were exposed to 5-day conditioned place preference (CPP) in order to evaluate drug-seeking behavior. The CPP scale was obtained by comparing the data from “pre-conditioning” and “post-conditioning” phases and it was used to evaluate morphine-dependence..
The results of the current study showed that the rats that received compulsory exercise had significantly less tendency towards morphine (P We conclude that compulsory exercise may reduce psychological dependence on morphine and could also be regarded as a proper complementary method for addiction prevention and preventing relapse..
