Reactive oxygen species (ROS) are cytotoxic agents that lead to significant oxidative damage. Bisphenol A (BPA) is a contaminant toxic, oxidative and estrogenic effects. Purslane is a promising natural product, which could be useful for the prevention of chronic diseases caused by oxidative stress. In this study 49 adult male rats (250 10g) were divided randomly in 7 groups (n=7): Control, Sham (500 ug corn oil\Kg BW), Toxin group (500ug BPA\kg BW), Positive control (100mg purslane hydroalcoholic extract\kg BW) and 3 purslane treated groups (500ug BPA + 50,100&150 mg purslane\kg BW). All injections are done by i.p rout in 14 consequently days. At the end of administration time (14 day) all animals were anesthetized with Chloral hydrate and sacrificed, then liver samples isolated to preparing tissue homogenates for measure antioxidant enzymes including SOD, CAT, TAC, GPX and MDA. Data are analyzed in SPSS statistical software by one way ANOVA with Tukey posttest. Analyzed data showed that MDA, TAC, CAT, GSH and GPX measures are modified in purslane treated groups compared to the bisphenol A group which indicates that the portulaca oleracea extract can improve the hepatotoxicity of bisphenol A induced.

Infertility as a crisis in marital relationships not only causes psychological problems, but can also act as a powerful blow against the relationship between the couple. The aim of this study was to compare the effectiveness of emotion-oriented couple therapy and Gottman couple therapy on sexual function, marital sexual satisfaction and depression in infertile couples. In this quasi-experimental study, 54 infertile couples from Omid Royan Infertility Center in Arak were selected and divided into two intervention groups (36 couples) and a control group (18 couples). In the intervention group, the training content was performed by emotion-focused couple therapy and Gottman couple therapy in ten 60-minute sessions for infertile couples, and two months later, the test was followed up. Data were collected using demographic information form, sexual function questionnaire, marital sexual satisfaction and depression and was analyzed using SPSS software version 23. The results showed that there is a difference between the effectiveness of emotion-oriented couple therapy and Gottman couple therapy on the sexual performance of men in infertile couples (P<0.05). However, there is no difference between the effectiveness of emotion-oriented couple therapy and Gottman couple therapy on women's sexual performance, marital sexual satisfaction of women and men, and depression of infertile couples. (P<0.05). Also, the results showed that both emotion-oriented couple therapy and Gottman methods were effective on sexual performance, marital sexual satisfaction and depression of infertile couples, and the scores of the post-test group and the follow-up period were better than the control group (P<0.05). The implementation of both methods of couple therapy has been effective on sexual function, marital sexual satisfaction and depression of infertile couples. Therefore, it is recommended that these two treatments including emotion-focused couple therapy and Gottman be used to improve sexual functioning, sexual satisfaction and marital depression of infertile couples.

According to the results of this study, it can be concluded that marital satisfaction in married women is related to factors such as sexual knowledge and sexual schemas; Therefore, empowerment and educational programs with the aim of increasing sexual knowledge and increasing interest between couples can play an effective role in improving the quality of marriage and increasing life satisfaction.

Ethanol is a strong pro-oxidant that causes cellular oxidative stress and damage, and it has a disruptive effect on cognitive abilities that can be caused by tissue damage. In this study, the tissue effects of ethanol alone and along with probiotic consumption were investigated on parts of the gray and white matter of the brain that are located in the vicinity of the lateral ventricles.

This experimental and case-control study was performed in the Physiology Research Laboratory of Islamic Azad University of Arak, Iran. 32 male wistar large rats (12 weeks) with an average weight of 250-300 grams were randomly divided into four groups of eight: (I) Negative control group: Mice were nasogastric tubed with only one milli - liter of phosphate buffer, (II) Probiotic group: 10 9 cfu/ml lactobacillus casei were nasogastric tubed for two months, (III) ethanol receiving group: ethanol at a concentration of 2g/kg, in - jected intraperitoneally for 30 minutes daily, (IV): probiotic-ethanol group: initially probiotic 109cfu/ml lactobacilli casei was nasogastric tubed for two months and ethanol injection at a concentration of 2g/kg was performed simultaneously in the last five days of the period. Histopathological study and analysis were performed using the H&E staining technique after sacrificing mice. Prism-GraphPad 9 software was used to analyze the data and charts. Groups were compared by one-side ANOVA and Tukey test was used to determine the differences be - tween each group.

The microscopic study showed observable pathological changes in the ethanol group (p<0.01). This group showed the highest injury due to vasogenic edema with Vir - chow-Robin space tension, hydrostatic edema, central chromatolysis, ischemic neuronal in - jury, and glial cell accumulation compared to the negative control group (p<0.0001). Tissue injury in the ethanol-probiotic group was15 to 25% reduced compared to the ethanol group (p<0.01). Healthy groups that receiving only probiotics had a healthy tissue pattern.

Probiotic supplement compensates for ethanol-induced tissue injury in the cor - tical and subcortical regions adjacent to the brainstem.

The use of antioxidant supplements improves and reduces oxidative stressfactors following intense intense exercise. Exhaustion was performed in female athletes.

14 female athletes with an age range of 20 to 28 years and a maximum oxygenconsumption of 42-52 m/kg/min in a quasi-experimental design randomly divided into two groups receivingcoenzyme Q10 supplementation and placebo (5 mg/kg body weight). Were. After 14 days ofcoenzyme Q10 supplementation, the subjects performed an intense, debilitating activity. Urine sampleswere collected in three stages (baseline, before and 24 hours after exhaustive activity) to determine theconcentration of 8-OHdG and MDA.

There was a significant difference of 62% in the increasing response of urinaryOHdG-8 to an exhaustingaerobic exercise session (P = 0.003). However, the 2% difference in the increasing urinary MDAresponse of the supplement and placebo groups was not significant after the last quasi-competitiveaerobic training session (P = 0.7).

According to the results of the study, two weeks of high-pressure aerobic training causesDNA damage and lipid peroxidation in female athletes, and supplementation with Q10 helps preventthe 8-OHdG response of female athletes after a strenuous high-pressure aerobic training session andreduces DNA damage.

The total statistical population was 600 couples (1200 people) and 146 couples (292 people) were selected as the statistical sample by available sampling method. Data collection tool: Hazan and Shiver Attachment Styles Scale Questionnaire (1993); Marital Conflict Scale Sanaei et al. (2000); Saatchi et al.'s Life Skills Scale (2010); The Larson Sexual Satisfaction Scale (1988) and the Sternberg Love Story Scale were standardized by (Alaei and Karami, 2007), all of which had validity and reliability. This study was a correlational study that was performed by structural equation modeling.

The results showed that both sexual satisfaction and love story can play a mediating role in predicting marital conflicts based on life skills and attachment styles.

Therefore, it can be concluded that sexual satisfaction can balance the relationship between attachment styles and marital conflict and reduce the rate of marital conflict. Also, the love story in the relationship between life skills and marital conflicts can reduce these conflicts.

Recognition of mechanisms involved in inflammatory disorders through the aging process and providing appropriate preventive or modulator strategies to improve quality of life are always important challenges in the field of life sciences. Therefore, the present study was conducted to determine the effect of two-month concurrent training (RT+HIIT) and caloric restriction on serum CRP and P65 amount in Peripheral blood mononuclear cells of inactive middle-aged men.

Twenty-four inactive, healthy men participated in three homogeneous groups: Caloric restriction (CR), Concurrent training (T) and Concurrent training with Caloric restriction (CRT) groups. Calorie restriction and energy cost in five days a week was about six kcal·kg-1·day-1. The concurrent training was included five days per week (two sessions of resistance training with 75 to 80% 1RM and three sessions of high intensity interval training with 80-85% heart rate reserve). Baseline and post-intervention p65 in the total and phosphorylated (p-p65) levels in PBMCs were assessed by ELISA. Serum CRP concentration was also measured using immunoturbidimetric.

Weight loss in CRT group was significantly higher than the other two groups (P < 0.05). However, the changes range in fat percentage, maximal oxygen consumption and one-repetition maximum (1RM) of T and CRT groups were significantly higher than CR group (P < 0.05). Changes in phosphorylated P65 and p-p65 / total p65 ratio in PBMCs of T and CRT groups were significantlyhigher than CR group (P < 0.05).

Based on the present results, two months of concurrent training and caloric restriction can reduce some of inflammatory markers in inactive men. In addition, the effect of concurrent training with and without calorie restriction on the initiators of inflammatory factors is greater than the calorie restriction intervention alone. Therefore, concurrent training and caloric restriction are recommended for prevention and confronting obesity and its inflammatory consequences, especially in middle age.

Findings indicated that there was an indirect relationship between the components of family functions such as relationship, emotional integration, role performance, problem solving, emotional accompaniment, behavior control, and overall performance and high-risk behaviors of students at a significant level less than 0.05. In addition, there was an indirect relationship between the internal and external religious orientation and high-risk behaviors at a significant level less than 0.05. Therefore, the problem studied is better to be considered by the officials due to the necessary training for families to identify high-risk behaviors of children and guide them and also the role of counseling centers of NAJA in social security increase and as a result the social investment of the police in order to prevent the emergence and spread of these behaviors.

 The most critical issue that the young generation faces is cyberspace, which has increased irrationally with the coronavirus outbreak. The present study aimed to identify cyberspace’s role in lifestyle, promoting health, and coronary anxiety in young people.

 The research method is descriptive post-event. The community included all undergraduate students of Tabriz Azad University, of which 307 people participated in the study through an online call answer to a Researcher-Made Questionnaires, which designed to measure the use of cyberspace, Corona Anxiety Questionnaire and the Lifestyle Promoters. Data were analyzed by multivariate analysis of variance and Post Hoc test.

 The findings show the components of lifestyle promoting health, subscales of spiritual growth (P=0.001), responsibility (P=0.016), interpersonal relationships (p=0.033), exercise (P=0.009) as well as the overall score of lifestyle (P=0.001); And one of the components of Corona Anxiety is a subscale of psychological symptoms (P=0.001) and also the total score of Corona Anxiety (P=0.001) in groups related to the use of cyberspace is significant, And students who spent more than four hours using cyberspace scored lower on health-promoting lifestyles and higher on coronary anxiety components.

 The excessive use of cyberspace has played a negative role in improving the health of students. Excessive and very little use of cyberspace also increases students’ anxiety, and in this regard, it is suggested that students manage the use of virtual social networks.

AbstractSirtuins have become prominent molecules in the aging process. Therefore, the present study was conducted to compare the effect of two months of concurrent training with and without calorie restriction on sirtuin-1 activity and content in the peripheral blood mononuclear cells (PBMCs) of inactive men. Therefore, thirty inactive men participated in three homogeneous groups: calorie restriction (CR: n=10), concurrent training (T: n=10), and concurrent training with calorie restriction (TCR: n=10). The calorie restriction was about -30 kcal•kg-1•week-1. The training consisted of five days a week (Resistance Training: two sessions / week-1, and High- Intensity Interval Training: three sessions / week-1). Sirtuin-1 content and activity in PBMCs were measured by ELISA and fluorometric assay, respectively. To measure oxidative stress, Plasma total antioxidant capacity (TAC) and serum malondialdehyde (MDA) levels were determined by FRAP and spectrophotometry, respectively. Data were analyzed using analysis of variance at a significance level ≤ 0.05. The results showed that Sirtuin-1 activity and TAC of all three groups were significantly increased after two-month interventions (p < 0.05). However, the changes in sirtuin-1 content and MDA levels were not significant in any groups (P> 0.05). Given the optimal changes in sirtuin-1 activity in PBMCs, TAC, and somebody composition components following two-months of concurrent training without calorie restriction, it can be concluded that concurrent training may be a more appropriate intervention for modulating the cell survival indicator in inactive men.

Moreover, the CDAS component of psychological symptoms (P=0.007) and its overall score (P=0.03) had a significant relationship with the way of using social media; the group with a fun purpose reported higher CDAS score than the groups with scientific and general information acquiring purposes.

 The use of social media for fun negatively affects the students’ lifestyle in the current coronavirus outbreak and increases their COVID-19-related anxiety.

Air pollution in different cities of the world is a complex mixture of toxic components, including particulate matter (PM), mainly produced by combustion processes. A cross-sectional analytical study was conducted to investigate the relationship between air pollutants and mortality from cardiorespiratory diseases in Mashhad. To this end, the data on mortality from cardiorespiratory diseases in 2012-2013 were obtained from Razavi Khorasan Health Organization. The mean daily concentration of air pollutants, including carbon monoxide (CO), PM with a diameter of 10 micrometers or less (PM10), and PM2.5 was calculated. The results of data analysis showed that there was a relationship between PM10 concentration and the rate of mortality from cardiovascular diseases in men. In addition, a significant relationship was observed between PM10 concentration and the rate of mortality from respiratory diseases in both men and women. The results indicated that there was a significant relationship between PM2.5 concentration and the rate of mortality from cardiorespiratory diseases in both men and women. There was also a significant relationship between CO concentration and the rate of mortality from respiratory diseases in women. The results demonstrated that PM2.5 has the greatest effect on mortality from cardiorespiratory diseases. The study findings were reported within the context of environmental communication by using the media tools to raise public awareness of the adverse effects of pollutants.

Multiple Sclerosis is (MS) is a common demyelinating disease of CNS that inflammation and stress oxidative processes have an important role in clinical courses and progression of it. The aim of the present study was to determine the anti-inflammatory effects of Melatonin on fatigue in MS. In a double-blind clinical trials study, 62 patients with relapsing remitting MS were randomized to oral Melatonin 3 mg or placebo daily for 8 weeks. Scale of Fatigue in MS was studied by assessing FSS (Fatigue Severity Scale) on weeks 1 and 8. Findings: 47 patients in intervention group and 15 patients in placebo group completed the study. In intervention group, treatment with Melatonin produced a significant decrease in FSS vs placebo group (before intervention: the average of FSS in patient group was 32.04±13.97 and in control group was 35.86±15.44; after intervention: the average of FSS in patient group was 30.42±12.40 and in control group was 41±12.66). Although in control group, the average of FSS was 35.866 and it was 41 after intervention. Because the score of placebo patient is near or upper than 36, this study suggested that Melatonin has a significant effect on improving and decreasing fatigue in MS. The use of melatonin alongside of First-line drugs such as mitoxantrone, IFN – B or glatimer acetate can improve fatigue and disability in patient with MS.

Statistical society of healthy people was the people on the same region that are selected by convevience sampling method and homogenized in the terms of age, sex and education level. The data collection tools are CERQ Emotion Regulation Questionnaire and psychological well-being questionnaire of reef. Multivariate analysis of variance (MANOVA) was used to compare two groups of multiple sclerosis patients and normal people in terms of scores of emotional regulation and psychological well-being.
Based on the results, psychological well-being components in normal people are significantly more than MS patients. Also, there is a significant difference between two groups of MS patients and normal people in terms of emotional regulation components.
The results show that there is a significant difference between people suffereing from MS and ordinary people based on their self-acceptance, autonomy, individual developememnt, being purposeful in life, having good relations with others and having control over the environment. The abovementioned elements in ordinary people are more than people suffering MS.

The etiology of some liver diseases is unknown, but oxidative stress has an important role in liver pathogenesis. Pistachio (Pistacia Vera) has compounds with known antioxidant properties, including coenzyme 10, vitamin E and beta-carotene. This study designed to evaluate protective effect of hydro-alcoholic extract of Pistacia Vera on liver enzymes following induction of hepatotoxicity.
In this experimental study 40 male rats (200-250 g) were divided into five experimental groups. Carbon tetrachloride (CCl4) was used to induce hepatic toxicity. In normal group, no intervention was done. Vehicle group received intraperitoneal injection of 50% CCl4. Treatment groups were gavaged by three doses of Pistacia Vera hydro-alcoholic extract (10, 50 and 100 mg/kg) for 1 month. Plasma activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total blood protein, plasma concentration of high density lipoprotein (HDL) and low density lipoprotein (LDL) were measured.
Gavage of different doses of pistachio extract in rats poisoned by CCl4 leads to decrease in plasma activity of AST and ALT and also the plasma concentration of LDL, while the plasma activity of ALP and plasma concentration of total protein and HDL were not changed in these animals.
Result of this study demonstrated that chronic gavage of pistachio hydro-alcoholic extract could decrease hepatotoxicity induced by CCl4. More investigation is needed for possible clinical usage of pistachio on liver insufficiency.
