Pregnancy creates considerable changes in the physical, emotional, and well-being of women. The aim of this study was to investigate the effectiveness of mindfulness training on the well-being and emotional control of pregnant women, and pregnant mothers in 2019.

This study was quasi-experimental with pre-test and post-test types. The statistical population of this study was all pregnant women (n = 26) in region 1 in Tehran in 2019, and sample was purposefully selected from nulliparous pregnant women, who had been referred to the Nikan Hospital. Participants were randomly assigned to mindfulness training (n = 16) and control (n = 11). An eight-session mindfulness program was conducted at the Nikan training facility, once a week, for 90 minutes. While the control group did not receive any training. Data were collected from Reef's Welfare Scale Questionnaire (1989), and Roger & Nesshoever Emotion Control Scale (1987). As part of the analysis, SPSS 24 was used to run ANCOVA and Covariance Analysis tests.

A covariance analysis test has shown that there was a difference between scores of well-being and emotional control among mindfulness training and in the control groups in the post-test phase.  There was a positive effect of mindfulness training on well-being and emotional control among pregnant women (p<0.001). According to the follow-up test, the interventions continued to affect well-being and emotional control.

Pregnant women at risk are advised to use mindfulness training interventions as a means to improve their well-being and emotional control.

The social situation of the society has progressed in a direction that the levels of tensions entering the educational environment has increased. Cognitive-behavioral therapy (CBT) training can be important in controlling stress and conflict in students. The aim of this study was to investigate the effect of cognitive-behavioral therapy training on the hardness and individual-social adjustment the in students of Dezful University of Medical Sciences.

A quasi-experimental study with pre-test-post-test design was performed on 200 students of Dezful University of Medical Sciences (100 in experimental group and 100 in control group) by random sampling method in 2020. Data were collected using standard questionnaires including hardiness (Kobasa) and adjustment. Data were analyzed by SPSS software version 16 using descriptive statistics including mean, standard deviation and repeated measures ANOVA.

In the post-training period of cognitive-behavioral therapy, there was a statistically significant difference between the mean total score of hardiness, adaptation and their dimensions in the two groups (P< 0.05). These differences were also observed in the follow-up phase after 4 months of intervention (P< 0.05).

The Cognitive-behavioral therapy has a positive effect on the level of hardness and adjustment of the students and also, this method of treatment can be used to promote students' health and mental health. It is suggested that this educational-therapeutic approach be used in the counseling centers and student psychological services.

The advent of technology and mass media, including virtual social networks, has led to changes in traditional education and educational interactions. Therefore, the present study aimed to investigate the relationship between the use of virtual social networks in educational interactions and students' academic performance with the mediating role of the quality of learning experiences of students at the Sabzevar University of Medical Sciences.

In this descriptive correlational study, 327 students of Sabzevar University of Medical Sciences in 2020 were surveyed by stratified relative sampling. In order to collect data, questionnaires were used on the use of social networks in educational interactions in Klimshastani (2016) and the quality of learning experiences of Newman (1990), and the criterion for measuring academic performance was students' Grade point average. Data were analyzed using SPSS 16 software and pearson correlation tests, multiple regression analysis and Sobel test.

The mean score of students in using social networks was in educational interactions (3.45± 0.88), learning experiences (3.65± 0.71) and academic performance (17.05± 1.42). Findings showed that there is a significant positive relationship (Z= 2.41, p <0.05) between the use of virtual social networks in educational interactions with students' academic performance with the mediating role of the quality of learning experiences. The use of these networks in educational interactions has a significant positive relationship with their academic performance (r= 0.72, p<0.05). There is a significant positive relationship (r = 0.61, p <0.05) between the use of virtual social networks in educational interactions with the quality of their learning experiences and the quality of learning experiences has a significant positive relationship with students' academic performance (r= 0.587, p <0.05).

Due to the significant relationship between research variables, it is suggested that in addition to face-to-face training, virtual education should be used to improve education.

Coronary artery disease is the leading cause of death and disability. Therefore, the prevention and management of this health condition are vitally important. The present study aimed to determine the effect of educational intervention based on Pender's health promotion model on health-promoting behaviors in patients undergoing coronary angioplasty.

This is a randomized control trial study, in which a total of 96 patients undergoing coronary angioplasty in Farshchian Heart Center in Hamadan in 2020 were allocated into two groups of intervention and control. The intervention group, in addition to the routine training in the control group, received 3 training sessions based on the Pender model. The Health-Promoting Lifestyle Profile II (HPLP II) was completed in both groups. Descriptive and analytical statistical tests and SPSS software version 16 were used to analyze the data.

The result showed that in both intervention and control groups, there was a statistically significant difference in the mean scores of the domains of health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, and stress management after the intervention (p<.001). Furthermore, in the control group, no statistically significant difference was found (p>0.05). But this difference was shown to be statistically significant in all domains in the intervention group (p<.001).

Based upon the results of the present study, the patient education based on Pender's health promotion model has a positive effect on health-promoting behaviors in patients undergoing coronary angioplasty, as this educational approach can be appropriate for improving the state of health in these patients.

In this study, we investigate the relationship between cancer and exposure to toxic substances in the environment. We used human encounters with them.

In this experimental study, 60 adult male mice were divided into four groups, including control, Malathion, Malathion with benzene and benzene. The control group was tested only with physiological serum. Except for the benzene group, all other groups were in skin contact with Malathion for 45 days was fed. After necropsy, tissue samples were taken from the target organs. In addition, cytotoxicity was assessed by MTT and micronucleus tests in vitro and the percentage of IC50 was determined. Microscopic observations of liver tissue showed hepatotoxicity and renal tissue renal toxicity in the Malathion group with benzene.

The percentage of frequency of micronuclei at concentrations of 100 /g / ml, 50 /g / ml, 25 /g / ml was significant in all groups compared to the control group (P <0.05). In MTT test, the percentage of cell growth inhibition at concentrations of 100 g/ml, 50 g/ml, 25 g/ml, and 10 µg/ml in all groups was significantly different from the percentage of inhibition of cell growth with the control group (P < 0.05).

According to the findings of this study, certain doses of Malathion alone and in combination with benzene cause cytotoxicity and pre-carcinogenicity in cytotoxicity tests. Malathion exacerbates the carcinogenic effects of benzene

It is hard to ignore attractive people. Paying attention to attractive individuals is a criterion that can estimate further motivation to make extramarital relationships. This whitethorn a threat to the stability of the marital relationship. The present study aimed to investigate the role of motivational and cognitive structure in the temptation to pay attention and communicate with attractive alternatives in married individuals.

With an available sampling method, the statistical population of the present study has consisted of married men and women who completed research questionnaires in an online design. That is, two hundred individuals met the research criteria and completed the questionnaires and the results were based on hierarchical multiple regression.

The results of hierarchical multiple regression analysis showed that among the covariate variables, gender was able to predict extramarital relationships. However, men were more inclined than women to be tempted by attractive alternatives and engage in extramarital affairs. In addition, the variables such as memory, inhibitory control, planning, and adaptive motivation provided a significant prediction of the temptation variable of extramarital relationships.

Based on the results of the present study, it appears that improving cognitive abilities (e.g., executive functions) and motivational structure, improve the degree of resistance to the temptations to make extramarital relationships with attractive alternatives.

Today, heavy metals and organic compounds such as dyes are among the most dangerous pollutants that have entered surface and groundwater and threaten human health. The aim of this study was to investigate the removal of reactive orange 3R dye and chromium by adsorption separately and simultaneously activated carbon.

In this study, Sycamore carbon modified with NH4Cl was used to remove contaminants.  Effect of variables such as pH (2-9), adsorbent concentration (0.5-1-0 g/L), pollutant concentration (10-50 mg/L) and contact time (2-40 minutes) on dye and chromium removal (simultaneously and separately) were calculated. Freundlich and Langmuir adsorption isotherm models and kinetics were also investigated.

The results of this study showed that activated carbon at pH = 4, 0.4 g/L adsorbent at 15 min contact time has the best removal conditions for both paint and chromium contaminants. Under optimal conditions, activated carbon was able to remove 72% of chromium and 84% of dye separately and 59% of chromium and 67% of dye simultaneously in solution at a concentration of 25 mg/L. The study of adsorption isotherms also showed that the experiments were more consistent with the Freundlich model.The absorption kinetics follows Pseudo-second order equations.

According to the results, this adsorbent has a good performance in separate and simultaneous removal of paint and chromium and can be used to treat wastewater containing organic and inorganic contaminants.

Life satisfaction in people with obsessive-compulsive disorder is lower than normal people in society, so by treating this disorder, the quality of life and life satisfaction in these people can be increased. The aim of this study was to compare the effectiveness of behavioral activation therapy and mindfulness-based cognitive-behavioral therapy on cognitive emotion regulation and cognitive-behavioral avoidance in people with obsessive-compulsive disorder.

The present study is an applied research and quasi-experimental method is a pre-test-post-test with a control group. The statistical population included patients with obsessive-compulsive disorder in Karaj in 1398. A total of 45 people were selected and randomly assigned to three groups of behavioral activation therapy, mindfulness-based cognitive-behavioral therapy and control group. Cognitive emotion regulation and cognitive-behavioral avoidance questionnaires were used to measure the effectiveness of treatments. For data analysis, descriptive statistics, multivariate analysis of covariance and post hoc test using SPSS-18 software were used.

The results of analysis of covariance showed that there is a statistically significant difference between the effectiveness of behavioral activation therapy and mindfulness-based cognitive-behavioral therapy in adaptive cognitive emotion regulation strategies (P=0.0001, F=57.71). But there was no statistical difference in the effectiveness of these two treatments in cognitive-behavioral avoidance. Both treatments have been equally effective in cognitive-behavioral avoidance.

Behavioral activation-based therapy and mindfulness-based cognitive-behavioral therapy have an effect on improving cognitive emotion regulation strategies and reducing cognitive-behavioral avoidance in patients with obsessive-compulsive disorder. Therefore, these two therapies can be used to regulate emotions and avoidance in obsessive-compulsive patients.

The aim of this study was to compare the effectiveness of mindfulness-based cognitive therapy and emotion-oriented therapy on psychological cohesion in type 2 diabetic patients.

The present study was applied in terms of purpose, with pre-test-post-test design, which used a quasi-experimental research design. The statistical population of the study included all people with type 2 diabetes who referred to Sabzevar Diabetes Clinic in 1398. From the mentioned statistical population, 45 people were selected by convenience sampling and randomly divided into 3 groups of 15 people (2 experimental groups and one control group). Antonovski (2006) answered the questionnaire of feeling psychological cohesion. In this study, descriptive data analysis was used to describe the collected data and the data were analyzed using SPSS statistical software.

The results showed that mindfulness-based cognitive therapy and emotion-oriented therapy are effective on mental cohesion in type 2 diabetic patients and there was no significant difference in their effectiveness

Cognitive therapies based on mindfulness and emotion-oriented therapy can be used to moderate the psychological problems of diabetic patients.

Premenstrual syndrome is one of the most common problems in women and causes some physical and psychological changes in women. This study was conducted to examine the structural pattern of cognitive emotion regulation based on sleep quality with the mediating role of marital satisfaction in women with premenstrual syndrome.

The method of the present study was correlational using structural equation modeling. The statistical population included all women diagnosed with premenstrual syndrome in 1398 and 1399 in Kermanshah, of which 380 people who were referred to the family planning clinic in Kermanshah were selected by convenience sampling method. The research instruments included the emotional regulation questionnaire (Garnefsky et al., 2001), Marital Satisfaction Questionnaire (Enrich), and the sleep quality index (Pittsburgh, 1989). The data were analyzed by the Spearman correlation method using SPSS-21 and LISREL software.

This study indicates the existence of a significant direct relationship between cognitive-emotional regulation strategies and overall sleep quality in women with PMS and also the quality of sleep directly and indirectly through marital satisfaction can be a good predictor for cognitive regulation of emotion in women with premenstrual syndrome.

It can be said that sleep quality and marital life satisfaction can play an important role in the cognitive regulation of emotion in women with premenstrual syndrome.
