Abstract
Introduction: The present study findings aimed to investigate the effect of exercises based on the American National Academy of Sports Medicine principles (NASM) on walking kinetics in piriformis syndrome in middle-aged men.
Methods: The current research was semi-experimental and laboratory-type. The statistical sample of the present study was 30 men with piriformis syndrome. Subjects were equally and randomly placed in two intervention and control groups. The intervention group performed NASM exercises for eight weeks. Before and after the exercises, the ground reaction force variables were measured using a Bartek force plate device with a sampling rate of 1000 Hz. Kinetic data were smoothed using a fourth-order Butterworth filter with a frequency cutoff of 20 Hz. For statistical analysis, analysis of variance and paired T-test were utilized at the significance level of P < 0.05.
Results: The findings of the present study showed that the effect of time on the FxHC and FyHC components at the peak of the forces and the FyHC component at the time of reaching the peak of the ground reaction force increased in the post-test compared to the pre-test. P > 0.025;
d = 0.64 - 0.96. The effect of the time factor in the FyPO component at the peak of the ground reaction force in the post-test was less than the pre-test (P < 0.025; d = 1.64-0.96). The interaction effect of the time × group in the FxPO component at the peak of the force and the FzHC component at the time of reaching the peak of the ground reaction force had a significant difference (P < 0.048; d = 0.87-0.83).
Conclusions: The NASM exercises used in this research can have a clinical and therapeutic effect that can reduce damage to the lower limbs and improve the quality of walking in people with piriformis syndrome.

Abstract
Introduction: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in industrialized societies. As an appetite inhibitory and energy balance regulator, nesfatin-1 plays a substantial role in the pathogenesis of obesity-related abnormalities. This study was conducted to determine the effects of 12 weeks of combined training (resistance training and high-intensity interval training (HIIT)) on the serum levels of nesfatin-1 and some liver enzymes in men with NAFLD.
Methods: In this semi-experimental study, 20 middle-aged men with NAFLD were randomly divided into two exercise and control groups. The exercise program included 12 weeks of combined training, featuring two sessions per week of resistance training and one session of HIIT. Body weight, body mass index (BMI), nesfatin-1 peptide, liver enzymes (ALT, AST, and ALP), lipid profile, maximal oxygen consumption (VO2max), and body fat percentage at the beginning and after 12-weeks were evaluated. Independent and dependent t-tests were analyzed to assess intra-group and inter-group differences, and the significance level was
P < 0.05.
Results: 12 weeks of combined resistance training and HIIT increased nesfatin-1 and decreased liver enzymes ALT, AST, and ALP in the exercise group compared to the control group and the pre-training stage (P < 0.05). We also observed an increase in VO2 max and a decrease in body weight, BMI, body fat percentage, and LDL in the exercise group compared to before starting the training protocol (P < 0.05).
Conclusions: Based on the results of the present study, it can be concluded that performing combined exercise training for twelve weeks led to an increase in nesfatin-1 peptide levels and a decrease in liver enzymes. It was suggested that this could be a cost-effective therapeutic approach recommended for patients with NAFLD.

Abstract
Introduction: Type 2 diabetes is a non-communicable disease that imposes a significant financial burden on the healthcare system each year. Numerous studies have demonstrated the involvement of inflammatory factors in the initiation and progression of this condition. The primary goal of this study is to compare the polymorphism of the interleukin 1 receptor antagonist gene among individuals with type 2 diabetes and those in the control group.
Methods: Following approval from the Ethics Committee of Gonabad University of Medical Sciences, blood samples were collected from 100 participants at Bohlool Hospital in Gonabad. These individuals were categorized into two groups: cases (individuals with type 2 diabetes) and controls (healthy individuals). DNA extraction was carried out using the salting out method. To examine the polymorphism, the specific segment was initially amplified through PCR with designated primers and then identified via gel electrophoresis. The data were analyzed using subjected to the Chi-square test at a significance level below 5%.
Results: Findings from the polymorphism analysis revealed a notable contrast in the genotype 2/1 (P = 0.001) and 2/2 (P = 0.004) within the case group when compared to the healthy participants. Specifically, individuals with genotype 2/1 exhibited a heightened risk of developing type 2 diabetes by up to 15 times.
Conclusions: Within the examined population, the polymorphism of the interleukin 1 receptor antagonist gene substantially influenced the predisposition to type 2 diabetes, amplifying the likelihood of developing this ailment. Individuals harboring allele 2 are at an increased susceptibility to type 2 diabetes.

Abstract
Introduction: Sexual self-efficacy is a fundamental concept in behavior, health, and sexual performance that changes over time due to events such as pregnancy and childbirth. The present study was conducted to investigate factors affecting sexual self-efficacy in pregnant women in Arak City.
Methods: The current research is a cross-sectional, descriptive, and analytical study conducted with 234 pregnant women aged 18 to 40 who had minimal reading and writing literacy and lived with their husbands. Ten comprehensive urban health centers were selected using cluster sampling. Data were collected through a demographic information checklist and a sexual self-efficacy questionnaire. Data analysis was done using Mann-Whitney U and Kruskal-Wallis and (LSD) tests.
Results: The mean score of sexual self-efficacy of pregnant women was 28.51 ± 6.45 and was at a high level. Kruskal-Wallis test showed that the sexual self-efficacy of pregnant women is unrelated to their education (P = 0.2). There is a significant relationship between education and the education of their spouses (P = 0.04). (LSD) test showed a significant difference between different levels of education of husbands and the sexual self-efficacy of pregnant women. Also, no significant relationship was observed between the mean score of sexual self-efficacy and other variables.
Conclusions: The sexual self-efficacy of pregnant women is related to the education of their husbands, so it is suggested to provide a suitable platform for increasing the knowledge and awareness of men.

Abstract
Introduction: The stress caused by COVID-19 had affected many people in society, especially individuals at risk. The present study was carried out to investigate, firstly, whether COVID-19-related stress plays a mediating role in the relationship between rumination and aggression in drug-dependent people undergoing treatment. Secondly, the study was conducted to know whether rumination has an indirect effect on the aggression of substance-dependent people under treatment through the mediation of COVID-19-related stress.
Methods: In this correlational analytical study, 136 patients undergoing maintenance treatment with methadone who were willing to enter the study were investigated by the available sampling method in two addiction treatment centers in the 1st and 2nd districts. The data collection tools in the present study included the Corona Disease Anxiety Questionnaire, Rumination Questionnaire, and Bass and Perry Aggression Questionnaire. After collecting the data, the anxiety score of each participant was measured from 0 to 54, the rumination score from 0 to 88, and the aggression score from 29 to 145. Then, the data was analyzed using Lisrel statistical software.
Results: Findings showed that the direct effect of rumination on aggression is 0.23, which is significant at the P < 0.01 level. Therefore, rumination has a positive and direct effect on aggression. Also, COVID-19-related stress plays a mediating role in the relationship between rumination and aggression in drug addicts under treatment. In addition, the indirect effect of rumination on aggression is 0.25, which is significant. Thus, rumination has an indirect effect on aggression through the mediation of COVID-19-related stress.
Conclusions: According to the high prevalence of psycho-social problems such as depression, anxiety, fear, addiction, job burnout, suicidal thoughts, violence, domestic and post-traumatic stress during the COVID-19 pandemic, in the post-corona era, we have witnessed a high amount of mental and social injuries in the world. For this reason, governments must screen psychologically vulnerable groups in advance.

Abstract
Introduction: Harmine is an alkaloid from the carboline family, belonging to the harmal plant, which has extensive applications in traditional medicine, with numerous studies highlighting its anti-cancer effects. Since biological processes are influenced by electromagnetic fields, the current study examined the anti-cancer effects of harmine and low-frequency electromagnetic fields on the expression of COX2, VEGF, and MMP-2 genes in the A2780 cell line.
Methods: In this experimental-laboratory study, ovarian cancer cell lines were randomly divided into four groups: control, harmine at concentrations of 6, 12, 24, 48, 96, and 192 micromolar, low-frequency electromagnetic field with an intensity of 50 Gauss, and harmine at a concentration of 48 micromolar with a low-frequency electromagnetic field of 50 Gauss intensity. Their toxicity was assessed using the MTT assay, nuclear morphological changes by DAPI staining, apoptotic effects of these compounds by measuring nitric oxide (NO), and gene expression changes by Real-Time PCR. Quantitative data were analyzed the ANOVA statistical test at a P < 0.05 level.
Results: Quantitative data comparison of this research indicated that harmine and a low-frequency electromagnetic field with an intensity of 50 Gauss caused a concentration-dependent reduction in the viability of ovarian cancer cells. Additionally, in the nitric oxide test, a significant decrease was found in the control group compared to the groups treated with a concentration of 48 micromolar and synergized with a 50 Gauss electromagnetic field (p<0.05). The expression of the aforementioned genes in treated cells showed a significant decrease. Treating ovarian cancer cells with harmine and its combined application led to significant nuclear morphological changes, including chromatin condensation, formation of apoptotic bodies, and wrinkling of the cell membrane.
Conclusions: The combined application of harmine and a low-frequency electromagnetic field induced apoptosis in A2780 cancer cells and resulted in the downregulation of COX2, VEGF-A, and MMP-2 gene expression. Consequently, the combined use of harmine with a low-frequency electromagnetic field, due to its effective cytotoxicity in inhibiting proliferation and inducing apoptosis, could be a suitable candidate for clinical studies.

Abstract
Introduction: The present study was conducted to analyze the focal relationship of the contribution of mental adaptation to cancer, health literacy, and perceived threat in predicting the early diagnosis of breast cancer.
Methods: This study was a descriptive correlational research. The statistical population of the present study included all women with breast cancer under treatment at Shohadaye Tajrish Hospital Cancer Treatment Center in 2023, and 310 people were determined to participate in the research using G*Power software and the available sampling method. They responded to Williams, Templin, and Hines's breast cancer literacy questionnaires, Champion's perceived threat questionnaire, Watson's mental adaptation to cancer and early diagnosis questionnaire. The data were also analyzed using a focal correlation test and multiple regression.
Results: The results showed that there is a significant relationship between the contribution variables of mental adaptation, perceived threat, and health literacy with the components of early cancer diagnosis (knowledge, attitude, and actions) (P ≤ 0.01). Also, the results showed that health literacy was 4.8%, mental compatibility was 3.4 percent and perceived threat 18.7% alone predicted the variance of early diagnosis of breast cancer. The perceived threat share is 38.9%, higher than all other variables.
Conclusions: Based on the statistical results, it can be said that increasing mental adaptability, perceived threat, and health literacy play a role in early disease diagnosis, and the importance of perceived threat is more significant than mental adaptability and health literacy, which should be considered.

Abstract
Introduction: Nowadays, the use of artificial intelligence and machine learning has impacted all fields of study. Utilizing these methods for identifying individuals' emotions through integrating audio, text, and image data has shown higher accuracy than conventional methods, presenting various applications for psychologists and human-machine interaction. Identifying human emotions and individuals' reactions is crucial in psychology and psychotherapy. Emotional identification has traditionally been conducted individually and by analyzing facial expressions, speech patterns, or handwritten responses to stimuli and events. However, depending on the subject's conditions or the analyst's circumstances, this approach may lack the required accuracy. This paper aimed to achieve high-precision emotional recognition from audio, text, and image data using artificial intelligence and machine learning methods.
Methods: This research employs a correlation-based approach between emotions and input data, utilizing machine learning methods and regression analysis to predict a criterion variable based on multiple predictor variables (the emotional category as the criterion variable and the features, audio, image, and text variables as predictors). The statistical population of this study is the IEMOCAP dataset, and the data type of this research is a mixed quantitative-qualitative approach.
Results: The results indicated that combining audio, image, and text data for multi-modal emotional recognition significantly outperformed the recognition of emotions from each data alone, exhibiting a precision of 82.9% in the baseline dataset.
Conclusions: The results demonstrate a considerably acceptable precision in identifying human emotions through audio integration, text, and image data compared to individual data when using machine learning and artificial intelligence methods.

Abstract
Introduction: One of the clinical manifestations of coronavirus is neurological symptoms. However, due to the emergence of this virus, little information is available about its symptoms. Therefore, this study aimed to evaluate the prevalence of neurological symptoms in patients with coronavirus at hospitals in Arak.
Methods: In this study, all patients hospitalized with COVID-19 in two hospitals in Arak who were willing to participate were selected by census. The questionnaires consisted of two parts: demographic information and the prevalence and severity of neurological symptoms, which were completed by interviews with patients.
Results: 208 patients with a mean age of 60.5±14.1 years participated in the study. Of the 20 neurological symptoms studied, only two (tingling around the mouth and cranial nerve palsy) were absent in patients. The most common neurological symptoms in patients were headache (82.5%), fatigue (81%) and muscle pain (74.9%), respectively. Also, according to the visual scale, participants reported the highest severity for headache (average: 7.5), followed by fatigue (average: 7.03), and muscle weakness (average: 6.9).
Conclusions: The results showed that the most common neurological symptoms in patients with coronary heart disease include headache, fatigue, and muscle pain and the most severe neurological symptoms in these patients are headache, fatigue, and muscle weakness. According to the findings of this study, these results can be used to diagnose patients and follow them up.

Abstract
Introduction: The fundamental role of marital satisfaction is vital in family formation and marriage survival. Marital dissatisfaction can make couples fail to solve their conflicts. Marital discontent, combined with job-related stress such as pre-hospital emergencies, can lead to heightened conflict in job responsibilities. It leads to the effect on personnel, patients, and their families. Therefore, this study aimed to investigate the marital satisfaction of pre-hospital emergency personnel at Qom University of Medical Sciences in 2023.
Methods: This cross-sectional study was conducted on 200 pre-hospital personnel of Qom University of Medical Sciences in May 2023. The sampling method was a stratified cluster. The data collection tool included the "Demographic Information" checklist and Enrich's "Marital Satisfaction" questionnaire. Data analysis was done using descriptive tests, Independent T-test, and Regression.
Results: The average age of the participants was 37.3 ± 7.06. More than half of the participants had a bachelor's degree. Most people had rotating shifts. The average score of marital satisfaction was 145.94 ± 22.21. Based on the results of the multivariate regression test, the variables of education, employment status, work experience, type of shift, having a second job, and having a job other than medical staff explain 63% of the variance of marital satisfaction of pre-hospital personnel.
Conclusions: According to the findings of the present study, in general, the marital satisfaction of pre-hospital emergency personnel of Qom University of Medical Sciences is at an average to high level. People with a fixed shift, with a second job, high work experience, without a fixed job status, and bachelor's and associate's degrees had less marital satisfaction than others. Therefore, managers and policymakers in the health field must pay more attention to the quality of family life, especially the married life of pre-hospital emergency workers with the mentioned conditions.

Abstract
Introduction: The main consequence of heart failure is a decline in patients' functional abilities, leading to limitations in occupational and social-family tasks, as well as impairments in cognitive and emotional health, ultimately resulting in a reduced quality of life. This research was conducted to assess the effectiveness of emotion regulation training in improving the quality of life and life expectancy of cardiovascular patients referred to health centers in Khorram Abad City.
Methods: The current research used a semi-experimental design of pre-test-post-test type and three-month follow-up with experimental and control groups. The statistical population of the research included all patients with cardiovascular diseases referred to the health centers of Khorram Abad City in 2023. Among the statistical population, 40 people were selected by direct sampling and randomly divided into two experimental (20 people) and control (20 people) groups. The experimental group was trained in emotion regulation during eight 90-minute sessions for 8 weeks. Both groups completed the World Health Organization Quality of Life Questionnaire (WHO-QOL-BREF) and Schneider et al.'s (1991) Life Expectancy Questionnaire in the pre-test, post-test, and follow-up. The multivariate covariance analysis method and Bonferroni post hoc test were used to analyze the results.
Results: The results showed that emotional regulation training is efficacious in improving the quality of life and life expectancy of cardiovascular patients (P < 0.01), and this effect remained stable in the three-month follow-up phase (P < 0.01).
Conclusions: Emotion regulation training is recommended to enhance cardiovascular patients' quality of life and life expectancy.

Abstract
Introduction: Physical activity causes cardiac hypertrophy by a non-pathological change in cardiac structure, called physiological hypertrophy. Several molecular changes are involved in this process. Insulin-like growth hormone-1 (IGF-1) is an important hormone involved in hypertrophy of cardiomyocytes. Also, the role of GATA4 as a possible gene involved in cardiac hypertrophy is controversial. Therefore, the present study was conducted to find the effect of aerobic and interval training on IGF-1, GATA4 gene, and cardiac tissue.
Methods: Eighteen male Wistar rats (243.72 ± 23.41 g) were randomly divided into control, aerobic, and interval training groups (n = 6). The aerobic group trained for 8 weeks/4 days a week/38 minutes/ 65% of maximum oxygen consumption (VO2 max). The intermittent group trained 8 weeks/4 days a week/5 set/4 minutes/85-90% of VO2 max running with 2 minutes rest between the sets. The weight of the heart and left ventricle, IGF-1 concentration, and GATA4 gene expression were measured 48 hours after the training. The evaluation was conducted with a one-way analysis of variance and Tukey's post hoc test at a significance level of 0.05.
Results: The weight of the heart and left ventricle increased significantly in trained groups. IGF-1 and GATA4 gene expression increased in both the training groups than the control group.
Conclusions: Aerobic and Interval training increases IGF-1, GATA4 gene, left ventricle, and heart weight. Considering the shorter time interval training takes, it seems that interval training is more beneficial than aerobic training.

Abstract
Introduction: Breast cancer is one of the most common cancers and the principal cause of death in women. One of the mechanisms of cancer cells for the lack of access to the immune system is the production of compounds suppressing immune responses, such as interleukin-10. On the other hand, vascular endothelial growth factor, by binding to its receptors on the surface of endothelial cells, plays a significant role in vascular permeability and tumor vascularity. In this study, the expression of interleukin-10 and vascular endothelial growth factor in breast tumor tissue was investigated in an experimental tumor model.
Methods: First, mammary tumors were experimentally induced in Balb/C mice, and RNA was extracted from the tumor tissue. cDNA was synthesized from the extracted RNAs, and the expression level of 10-IL and VEGF genes was evaluated by RT-PCR.
Results: The results of data analysis showed that the expression of IL-10 and VEGF genes in the tumor tissue was higher than in the cells of the control group, but this increase in expression was not statistically significant.
Conclusions: In general, the expression level of Interleukin-10 and VEGF genes was increased in the experimental tumor model, but broader research and the correlation with other involved factors seem necessary.

Abstract
Introduction: Physical activity positively influences various physiological factors, laying the groundwork for beneficial changes. Myostatin and follistatin are among these factors, whose levels are influenced by gender and physical activity. The present study was conducted with the aim of investigating the effect of traditional resistance training (RT) and high functional training (HIFT) on the serum levels of myostatin and follistatin in young women.
Methods: In this semi-experimental study, 30 young women were selected and divided into three groups: intense functional training, traditional resistance training, and control. Blood was drawn 24 hours before and 48 hours after the end of the interventions to measure the serum levels of myostatin and follistatin. The exercise protocols were performed for eight weeks, 3 days a week and 60 minutes a day. Ultimately, the collected data were analyzed using the ANOVA statistical method, with a significance level set at P < 0.05.
Results: The results showed that follistatin level was significantly higher in the RT and HIFT groups than in the control group (P = 0.001). Also, the amount of follistatin in the HIFT group was considerably higher than the RT group (P = 0.01). The results showed that the level of myostatin in the RT and HIFT groups was significantly lower than the control group (P = 0.001). Also, the amount of this factor in the HIFT group was substantially lower than in the RT group (P = 0.01).
Conclusions: In general, the findings of the present study show that performing intense resistance and functional exercises causes a favorable change in the expression of physiological factors related to muscle growth in women. It seems that the effect of intense functional exercises is greater than resistance exercises.

Introduction: Reducing physical activity as well as consuming more calories than the body needs increases obesity and its related disorders, such as metabolic syndrome. Therefore, this study aimed to determine the effect of eight weeks of high-intensity interval training (HIIT) and resistance training (RT) on brain tissue gene expression of AKT2 and insulin resistance in obese Wistar rats.
Methods: 30 male rats weighing 160 to 185 grams were fed a high-fat diet for 12 weeks. After the approval of the obesity protocol of increasing the weight of the rats, which to be more than 300 grams, the rats were divided into three groups, including the control group (n = 10), HIIT group (n = 10), as well as RT group (n = 10). Until the end, the rats continued to eat a high-fat diet. HIIT was performed for eight weeks and five sessions per week, with an intensity of 80 to 95% of maximum oxygen consumption on a treadmill. Moreover, RT was performed with an intensity of 40-60% of a maximum repetition on the ladder. After eight weeks of training interventions, the expression level of the AKT2 gene in brain tissue was measured by the real-time PCR method.
Results: The results of the present study demonstrated a significant increase in AKT2 gene expression of HIIT and RT groups compared to the control group (P < 0.05). Furthermore, the results illustrated that the insulin resistance of rats in both training groups was significantly reduced (P < 0.05).
Conclusions: According to the findings of the present research, it could be concluded that HIIT, as well as RT interventions, probably causes an increase in AKT2 gene expression and could be effective in reducing insulin resistance and improving glucose profile.
