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: 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.

Abstract
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.

Abstract
Introduction: One of the problems during adolescence is the existence of conflict with parents, which creates object relationships and feelings of shame and guilt in them. This research was conducted to determine the effectiveness of treatment based on the mentalization of object relations and feelings of shame and guilt in conflicting mother-child relationships.
Methods: This research method was semi-experimental and pre-test-post-test with a control group. The statistical population of this research included all mothers and adolescents with conflicting relationships who were referred to counseling centers in Shiraz in 2022. By using the available sampling method, 30 people from the mentioned community were selected as a sample and were randomly divided into two experimental (15 people) and control (15 people) groups. Asadi et al.'s parent-child conflict questionnaires (2010), Bell's object relations (1995), and Cohen et al.'s (2011) feelings of shame and guilt were used to collect information. The experimental group underwent executive function training for 13 sessions twice a week for 60 minutes, and the control group did not receive any training. The research data was analyzed using correlation.
Results: The mean ± standard deviation of the experimental group in the post-test in the variable of object relations from 1.5 ± 1.37 to 28.6 ± 4.3 and in the variable of shame and guilt from 5 ± 1.60 to 5.60 ± 3. 51.2 ± 9.1 decreased. The results showed that in the post-test stage, the mean scores of object relations and feelings of shame and guilt in the experimental group decreased significantly compared to the control group (P < 0.01).
Conclusions: Treatment based on mentalization was effective in improving object relationships and reducing feelings of shame and guilt. Therefore, this treatment can be suggested to reduce the conflict between adolescents and mothers.

Abstract
Introduction: Dermatoglyphic is a science that study the lines in the skin of the palms and fingertips properly. In some studies, the relationship between dermatoglyphic patterns with some diseases has been proven Arthritis Rheumatoid is a chronic inflammatory disease with autoimmune pathogenesis. The aim of this study was to investigate the qualitative and quantitative characteristics of dermatoglyphics in people with rheumatoid arthritis compared to the control group.
Methods: This case-control study was conducted on 50 patients with rheumatoid arthritis and 50 people in the control group living in Mashhad. The fingerprint was recorded by the scanner. The distribution of the frequency of fingerprint patterns, including Arch, Loop and Whorl, along with the counting of fingerprint lines in both groups was investigated. Finally, the obtained data were analyzed using ANOVA and X2 tests.
Results: According to the results, the maximum frequency of dermatoglyphic patterns in both hands was related to the ulnar loop type. After that, in the patient group, simple Whorl patterns and double Whorl patterns and in the healthy group, double Whorl patterns and simple Whorl patterns were the most frequent. Between the average finger ridge count in the right hand of healthy people with the right hand of patient’s people and the left hand of healthy people with the left hand of patient’s people showed a significant difference in the error level of 0.05.
Conclusions: It seems that this difference can be used as a biological diagnostic marker to screen people prone to rheumatoid arthritis. This information in prognosis of psychological, medical and therapeutic plans, issues related to anthropology and social sciences can also be useful.

Abstract
Introduction: The Symptoms of Omicron are still unknown. Primary data show that the Omicron symptoms are mainly related to the respiratory system, including runny nose, sore throat, headache, fatigue, and sneezing. Based on the need for more evidence about Omicron symptoms, this study was conducted to investigate the symptoms of this COVID serotype.
Methods: This descriptive-analytical cross-sectional study was performed for 6 months in Arak city on 160 definitively diagnosed patients with Omicron. For all patients who entered the study, the information evaluation checklist, including demographics and symptoms (24 symptoms), was completed. Disease diagnosis was done by PCR.
Results: The disease of 55% of people was mild, 35% moderate, and 10% severe. Fifty-one people (31.9%) mentioned a history of previous infection with COVID-19. Pulmonary involvement, the type of drug used, and anxiety at the time of infection were related to the severity of the disease (P < 0.05). The five most common symptoms of Omicron (%) were sore throat (86.3), cough (82.5), weakness and lethargy (76.3), headache (72.5) and dry mouth (62.5). There was also a relationship between old age with dry mouth and headache, underlying disease with sneezing, anxiety during illness with joint pain and chest pain, and smoking with abdominal pain (P < 0.05).
Conclusions: The most common symptoms included sore throat, cough, weakness and lethargy, headache, and musculoskeletal pain. However, reduced smell and taste, night sweats, fever, and joint pain, common in the previous serotypes, were among the less frequent symptoms of Omicron.

Abstract
Introduction: Exercise and physical activity have always been recommended as a core treatment for knee osteoarthritis. However, it is unclear which types of exercises have the most splendid effect on this condition. This study aimed to evaluate the impact of two methods of water exercise (Traband exercise and NASM exercise) on pain and motor function in women with knee osteoarthritis.
Methods: In this semi-experimental study, with a design pre and post-test and a control group, 45 women with knee osteoarthritis with an average age = 56.5 years and a BMI = 29.04 kg/m2 were purposefully selected and divided into three groups (n = 15); Water Exercise with Theraband, Water Exercise with the NASM Approach and Control randomly. An exercise protocol with Theraband and NASM approach (approved by the Medical College of Georgia for patients with knee osteoarthritis) was performed for eight weeks, three sessions per week, and each session lasted about 60 minutes in the water. Visual Analog Scale (VAS) and physical performance tests of the Osteoarthritis Research Society International (OARSI) were used to estimate the study variables. MANCOVA and post hoc Bonferroni tests were conducted to analyze the data at a significant level (P ≤ 0.05).
Results: The results showed that, similarly, in both experimental groups, the amount of pain and the time of tests TUG, 40MW, and SCT decreased significantly (P≥ 0.05). In addition, in both experimental groups, there was a significant increase in the scores of the 30-S-CS and 6MWT tests (P≥ 0.05).
Conclusions: These results showed the beneficial effects of training in water with the traband and training in water with the NASM approach on pain and motor performance indicators. Therefore, the use of these training methods is recommended as a suitable prevention and treatment method for knee osteoarthritis.

Abstract
Introduction: Different training methods increase performance capabilities in addition to metabolic changes in body organs. The present study aimed to compare the effect of endurance and strength training on anthropometric indicators, glucose changes, fat metabolism, and irisin levels of young male students.
Methods: Thirty-six obese students (age: 21.19 ± 2.43 years; weight: 88.59 ± 6.20 kg; height: 175.41 ± 12.96 cm; body mass index: 30.45; fat percentage: 25.73%) were randomly placed in one of control, endurance, and strength training groups (n= 12). The strength training group trained for 8 week/3 session/4 sets/10 repetitions/ from 50 to 70% of the one repetition maximum (incremental manner, every 2 weeks), and the endurance training group trained for 30 minutes of aerobic jogging with 60 to 80% heart rate maximum. Plasma irisin, glucose, insulin, insulin resistance, fat percentage, body mass index, weight, waist circumference, and hip circumference were measured. The data were analyzed by one-way analysis of variance and Tukey's test at 0.05.
Results: Body weight (P = 0.03), fat percentage (P = 0.04), and body mass index (P = 0.04) significantly decreased in the post-test of endurance training group. Irisin level in the post-test in the control group had a significant difference with endurance and strength training (P = 0.01 and P = 0.02, respectively). Insulin in the post-test of the control group was significantly different from the endurance and strength group (P = 0.00 and P = 0.00, respectively). The level of insulin resistance in the post-test of the endurance and strength group had a significant difference compared to the control (P = 0.00 and P = 0.00, respectively).
Conclusions: Eight weeks of aerobic treadmill training and strength training with free weights can improve body composition, increase irisin levels, and reduce insulin resistance in obese male adolescents.

Abstract
Introduction: Novel antidiabetic medications are employed to manage glycemic control and mitigate the long-term complications of type 2 diabetes. This study aimed to investigate the prevalence of adverse events, including hypoglycemia, associated with these novel antidiabetic agents in a cohort of patients with type 2 diabetes.
Methods: This cross-sectional analytical study was conducted on 157 patients with type 2 diabetes mellitus attending the Endocrinology Clinic at Imam Khomeini Hospital, Urmia, during the summer of 2024. A convenience sampling method was employed to recruit participants. Data on demographics, the incidence of hypoglycemia, and reported adverse drug reactions were collected from all eligible patients through a structured interview. Subsequently, patients were stratified into three treatment groups based on the specific novel antidiabetic medication they received.
Results: In patients receiving sitagliptin, the most prevalent adverse events included arthralgia and rheumatic problems (26.31%), dermatological manifestations (36.84%), and allergic reactions (21.06%). Nausea (52.94%) and abdominal pain (17.65%) were the most frequent adverse events observed in patients treated with liraglutide. Polydipsia (28.72%), weakness and lethargy (26.6%), and dry mucous membranes (27.66%) were commonly reported in patients receiving empagliflozin. Hypoglycemia was observed predominantly in male patients aged 51-55 years receiving sitagliptin.
Conclusions: The findings of this study demonstrate a low incidence of hypoglycemia among patients treated with modern antidiabetic medications. Prevalent short-term adverse events observed included gastrointestinal disturbances, allergic reactions, and dermatological manifestations.

Abstract
Introduction: Imaging of the vascular system supplying the brain parenchyma is a diagnostic tool in the evaluation of stroke patients. This study aimed to compare the results of digital subtraction angiography with color Doppler ultrasound of the carotid arteries in patients with ischemic stroke.
Methods: In this cross-sectional-analytical study, the medical records of patients with ischemic stroke admitted to Imam Khomeini Hospital from July 1401 to July 1402 were reviewed to collect data. Demographic information, along with the results of color Doppler ultrasound and digital subtraction angiography of the patients, were extracted and evaluated.
Results: This study included 48 patients with ischemic stroke with a mean age of 12.8 ± 0.67 years. Hypertension was present in 68.8%, diabetes mellitus in 20.8%, and smoking in 25% of patients. Based on the results of digital subtraction angiography and color Doppler ultrasound, the most common vascular abnormality was plaque (79.2%). Vascular stenosis and occlusion were present in 91.7% of patients. Color Doppler ultrasound in examining the right and left internal carotid arteries had a sensitivity of 94.9% and 92.8%, specificity of 66.7% and 38.9%, positive predictive value of 92.1% and 70.3%, and negative predictive value of 75% and 77.8%.
Conclusions: Color Doppler vascular ultrasound demonstrated high sensitivity and specificity in detecting the presence and severity of stenosis in internal carotid arteries of ischemic stroke patients, supporting its use as a non-invasive and cost-effective method in clinical practice.
