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: The thickness of the molecular and pyramidal layers in the hippocampus represents a pivotal aspect of Alzheimer's research. This study was conducted to investigate the effect of swimming endurance, resistance, and combined exercises on the molecular and pyramidal layers of the hippocampus tissue thickness of Alzheimer's rats.
Methods: In this experimental study, 40 large white Wistar laboratory rats (6 weeks old; Weight 180-200 g) were randomly and equally divided into five groups: healthy control, Alzheimer's control, endurance, resistance, and combined. Alzheimer's disease was induced by intraperitoneal injection of trimethyltin chloride (8 mg/kg). Two weeks after the injection and confirmation of Alzheimer's induction, the training protocols of endurance (5-sessions/week, the first to the fourth week incrementally from 5-15-min to 45-min of swimming, the fifth to the twelfth week 60-min of swimming), resistance (5-sessions/week, The first week of familiarization with the exercise, week 2; 30%, week3-5; 70-90%, week6-8; 100-110%, week9-10; 120-130%, and week11-12; 140-150% of body weight), combined (2 resistance sessions/week and three endurance sessions/week) was performed for 12 weeks. Forty-eight hours post-intervention, animals were dissected, and hippocampus tissue was harvested. Finally, the data were analyzed at the significance level of P < 0.05.
Results: The thickness of the molecular and pyramidal layers of the hippocampal tissue of Alzheimer's animals decreased compared to healthy animals, and all three endurance, resistance, and combined exercise protocols increased layers (P < 0.001). However, the increase in the molecular and pyramidal layers thickness of the hippocampal tissue of combined group rats compared to the endurance and resistance group had a greater increase (P < 0.01).
Conclusions: These findings highlight the changes in the thickness of the hippocampal tissue layers concerning Alzheimer's pathology and the effect of combined exercises on this parameter. While exercise may have positively affected hippocampal volume and synaptic plasticity, more research is needed to fully understand the impact of exercise on hippocampal layer thickness in Alzheimer's.

Abstract
Introduction: The purpose of the "Health Communication" discussion plan, the most serious sparks of which were struck in the minds with the emergence of the COVID-19 pandemic in 2019, revealed the importance of paying attention to improving health communication more than ever. For this purpose, in the current study, the formulation of a conceptual model of health communication capacities in pandemic conditions was examined from the perspective of health system experts.
Methods: This research was conducted using a qualitative approach and the foundation's data theory method. Sampling was done with a purposeful snowball method, which included 20 communication and media professors and health professionals. Data collection was done through semi-structured interviews and document reviews based on the systematic approach of Strauss and Corbin (open, central, and selective coding), which includes causal conditions, central idea, context, mediating conditions (intervenor), strategies, and consequences of analysis. Validation was done through the review of participants and experts in the health system.
Results: The findings of the research in the grounded theory section show that the dimensions of the paradigm model include the central phenomenon: health communication (effective and informative communication), causal conditions: health communication harms (infodemic), the context of harms (widespread and popular media, lack of authority of the health unit, mass information, politicization), strategies (holding officials accountable, reliable sources and producing practical content, anxiety management, avoiding exaggeration of people's participation, teamwork and combination of experts, using the experiences of other countries) and consequences including (attracting trust and forming beneficial relationships) took place.
Conclusions: According to the dimensions achieved in presenting the model for improving health communication capacities in pandemic conditions in the country, it can be said that on the one hand, "transparency and immediacy of information" and the other hand, "empathy and trust between people and officials" in such More than one situation should be considered.

Abstract
Introduction: In a stressful work environment, individuals experience burnout; meanwhile, social support helps to reduce burnout. Therefore, the current research has investigated the effect of organizational climate on the burnout of employees of selected healthcare centers in Arak City, considering the moderating role of social support in 2023.
Methods: The current research is applied, exploratory, and developmental in terms of purpose. Random sampling and based on Cochran's formula from 134 healthcare workers working in the health center, the questionnaire was completed. Demographic information forms, Maslach's (1993) job burnout questionnaire, Halpin and Kraft's (1963) organizational climate questionnaire, and Zimmet's (1988) perceived social support questionnaire were used to collect data. The results of model structure reliability tests, Cronbach's alpha values, composite reliability values, and rho_a, which indicate the internal correlation of questions of a variable within the model, are higher than 0.7 and have acceptable structure reliability. All the values of the HTMT index were less than the permissible value of 0.9 and were at a satisfactorylevel. Consequently, this test also confirmed the divergent validity.
Results: The results with P > 0.001 and a 99% confidence level of the organizational atmosphere had an inverse effect on emotional burnout and depersonalization and directly impacted individual success. The perceived social support variable did not have a moderating role on the causal relationship of organizational climate with emotional burnout and depersonalization and its direction was reversed. However, it had a strengthening role in individual success and direct direction. In other words, people with more social support have more powerful personal success and vice versa.
Conclusions: Organizational climate is one of the variables of job burnout, and people with higher social support have less job burnout. Therefore, it is suggested that managers conduct in-service training focusing on the components of job burnout and perceived organizational climate. In addition, friendly relations should be established with employees to increase social support, and rewards and welfare measures should be granted.

Abstract
Introduction: Glyphosate is the most popular broad-spectrum herbicide globally due to the growing demand for glyphosate-resistant crops. Glyphosate exhibits harmful properties, including cytotoxicity, neurotoxicity, and reproductive toxicity. This study aimed to investigate the detrimental effects of glyphosate on ovarian histopathology in mice and the in vitro maturation (IVM) of oocytes following superovulation.
Methods: In this study, thirty-two female NMRI mice were randomly divided into the following groups: control, glyphosate, superovulation, and superovulation-glyphosate. Animals received glyphosate (0.5%) continuously through drinking water for three weeks. HMG and HCG were used to induce superovulation. Oocytes were collected from the ampulla, and the quantity and quality of oocytes were analyzed. Then, in vitro maturation (IVM) of oocytes was performed. At the end of the study, ovarian histopathology was analyzed.
Results: Compared to the control group, the glyphosate-treated group exhibited a significant decrease in secondary and Graafian follicles while demonstrating a concomitant increase in atretic follicles (P < 0.05). Additionally, the superovulation-glyphosate group showed fewer germinal vesicle breakdown (GVBD) and MII oocytes than the superovulation group. In the superovulation-glyphosate group, there was a notable reduction in GVBD and MII oocytes following in vitro maturation (IVM).
Conclusions: Glyphosate has the potential to damage ovarian tissue and adversely affect IVM and oogenesis.

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 growing increase in the elderly population requires more research to identify the health priorities of this group, especially in critical situations such as the COVID-19 pandemic. Therefore, the current study was conducted to determine the influential components of marital satisfaction and its relationship with lifestyle in Urmia City in 2021.
Methods: In this descriptive-analytical and cross-sectional correlational study, 220 married elderly living in Urmia were selected through cluster sampling. The Miler's life satisfaction and Haynes's marital satisfaction questionnaires were used in addition to the demographic questionnaire to collect data in this research. Data were analyzed using descriptive statistical tests (mean and standard deviation, frequency, and percentage) and analytical (Pearson correlation coefficients and multiple linear regression) at a significant level of P ≤ 0.05.
Results: A step-by-step multiple linear regression model also revealed that variables of lifestyle (ß = -0.364), age (ß = 0.425), number of children (ß = 0.143), occupation (ß = 0.425) and illness (ß = 3.608) - had the most considerable contribution in the sensitive prediction of marital satisfaction. The regression model excluded other demographic variables.
Conclusions: This study showed that lifestyle and demographic variables such as age, number of children, occupation, and illness have the greatest contribution in predicting marital satisfaction. Therefore, it seems necessary to design counseling services in comprehensive health centers for this group so that counselors can teach healthy lifestyles to older adults to improve marital relationships.

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: Sociodemographic factors and perceived anxiety have a significant impact on the development of somatic symptom disorder. This study aimed to investigate the role of demographic characteristics, social isolation, and perceived anxiety in predicting somatic symptom disorder.
Methods: In a cross-sectional descriptive study among adults aged 18 to 60 in Tehran in 2023, 437 participants were selected based on convenience sampling. The participants completed the Somatic Symptom Disorder Questionnaire (SSEQ), Social Isolation Questionnaire, and Perceived Anxiety Questionnaire. Data were analyzed using Pearson’s correlation and multiple regression analysis.
Results: The results indicated that social isolation and perceived anxiety have a positive and significant correlation with somatic symptoms disorder (P < 0.01). There was no correlation between demographic characteristics (age, gender, marital status, education, and employment status) and somatic symptoms (P <0.01). Multiple correlation and regression coefficients among research variables were statistically significant (P < 0.01).
Conclusions: The examined model was almost able to predict 22% of the somatic symptoms of the disorder. The results have implications for formulating interventions based on social isolation and perceived anxiety in controlling somatic symptoms. It is essential to pay attention to social isolation and perceived anxiety in the formulation and implementation of interventions and educational programs for the prevention and improvement of somatic symptom disorder.

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: Nowadays, plant-derived compound is widely used in medical treatment as complementary therapies. Rosemary is one of these plants that have anti-angiogenic and anti-tumor effects. However, low solubility and low bioavailability lead to limited use of this compound. To overcome this limitation, the use of liposomes is beneficial. So, this study aimed to prepare liposomes containing rosemary alcoholic extract to obtain the best formulation with best properties to use in the antitumor study.
Methods: Liposomes were prepared by Thin-Film-Hydration method in different ratios of rosemary extract, hydrogenated-soybean-phosphatidylcholine (HSPC), Cholesterol, and mPEG2000 (F1-F6). The characterization of nanoliposomes includes size, PDI (Poly dispersity index), zeta potential, encapsulation efficiency, and release rate was measured.
Results: The results showed that the average particle size and zeta potential were 113.4 nm and -10.8 mV, respectively. Encapsulation efficiency showed a range of 60- 90%. The average release rate of the extract was about 60%. Also, the results showed that the F1 formulation was transparent, had appropriate properties, and did not precipitate. F2 formulation was not transparent. F3-F4 formulations were precipitated, and F5-F6 formulations did not achieve the appropriate size.
Conclusions: This study proved that F1 formulation in a ratio of 55:30:5 HSPC/chol/mPEG2000 is the best formulation for the preparation of nanoliposomes containing rosemary alcoholic extract to achieve the best properties for use in cancer studies.

Introduction: The present study was conducted to investigate the effectiveness of acceptance and commitment-based therapy on the lifestyle of improving the health and emotional distress of women undergoing infertility treatment with the in vitro fertilization (IVF) method.
Methods: The method of this study was semi-experimental with a pre-test-post-test design with a control group and a follow-up stage. The statistical population of the study included women undergoing infertility treatment with the IVF method referring to the infertility center of Imam Khomeini Hospital in Tehran in the first six months of 2012. In this research, 27 women undergoing infertility treatment with IVF method were selected by voluntary sampling method and replaced by random method in test and control groups. The experimental group underwent acceptance and commitment therapy (10 sessions) for two and a half months. A health-promoting lifestyle questionnaire (HPLP) and an emotional distress questionnaire (Lavibond and Lavibond, 1995) were used as research tools. The data were analyzed using a mixed analysis of variance and Bonferroni post hoc test.
Results: It showed that the treatment based on acceptance and commitment to the lifestyle level improves health (Eta = 0.56, F = 19.74) and has a significant effect on the dimensions of emotional disorders such as depression (P < 0.0001, Eta = 0.58, F = 0.58). F = 34), anxiety (P > 0001; Eta = 0.59; F = 35.69), and stress (P > 0.0001; Eta = 0.61; F = 40.12) of women undergoing infertility treatment with the IVF, and has been able to lead to increase a healthy lifestyle, reduce depression, anxiety, and stress in these individuals.
Conclusions: Acceptance and commitment therapy, utilizing six psychological acceptance processes, cognitive breakdown, self under context, interaction with the present, specified values, and committed behavior, can be used as an effective treatment to reduce emotional distress in women undergoing IVF infertility treatment.

Abstract
Introduction: This study aimed to investigate the effects of insulin drug therapy on the kidney structure of offspring of insulin-treated diabetic mice.
Methods: After pregnancy, female Sprague-Dawley rats were divided into control, sham, diabetics induced by streptozotocin, and diabetics receiving insulin groups. Diabetic rat offspring were sacrificed on the 10th day after natural childbirth, and the left kidneys were studied for morphometric and histological studies.
Results: The weight of children of diabetic mothers showed a significant decrease compared to children of healthy mothers (P < 0.001). The weight of the offspring of diabetic mothers receiving insulin did not show a substantial change compared to the offspring of diabetic mothers. The weight of the kidneys of the offspring of diabetic mothers showed a significant decrease compared to the control group. However, the weight of the kidneys of the offspring of diabetic mothers receiving insulin did not increase compared to those of diabetic mothers. The results of the kidney sections stained with hematoxylin-eosin and trichrome Masson showed that the offspring of diabetic mothers treated with insulin did not show a significant improvement compared to the control group.
Conclusions: Although the use of insulin is one of the momentous therapeutic ways to control blood glucose in diabetics, it cannot significantly lead to the normal health of the kidneys of the offspring of diabetic mothers under insulin treatment.

Abstract
Introduction: Considering the synthesis and secretion of irisin and BDNF from muscle tissue during exercise and the possible relationship of these factors with improving muscle strength and performance, the present study aimed to investigate the effect of 12 weeks of strength training on muscle strength, body fat percentage, irisin, and BDNF in inactive middle-aged women.
Methods: In a semi-experimental study, 20 inactive middle-aged women (mean age 37.70 ± 5.91 years, weight 79.80 ± 5.82 kg) were selected and randomly assigned to two strength training groups (n = 10) and control groups (n = 10). The training group performed 12 weeks of strength training, three sessions per week at an intensity of 65 to 80% of maximum strength. Then, blood samples were taken using ELISA to measure irisin and BDNF. Independent t-test and Pearson correlation test were used to analyze the data. The significance level (P ≤ 0.05) was considered.
Results: Strength training significantly increased serum irisin concentration (P = 0.035) and serum BDNF concentration (P = 0.058) and also considerably decreased body fat percentage (P = 0.058) in middle-aged women. There was also a positive and significant relationship between lower body strength and serum irisin levels (P = 0.040). The Results from the Pearson correlation test indicate a significant positive relationship between BDNF and upper body strength (P = 0.038).
Conclusions: Based on the results of the present study, it seems that increased secretion of serum irisin and BDNF hormones is related to increased muscle strength following strength training in middle-aged individuals.

Abstract
Background and Purpose: Emergency medical technicians (EMTs) are the frontline medical personnel who often face stressful and critical situations. Job hardiness can enhance their capacity to withstand challenging circumstances and both physical and mental pressures. Therefore, this study was conducted to identify the level of job hardiness among EMTs and its associated factors.
Materials and Methods: This study employed a cross-sectional descriptive design involving 216 EMTs from Qom University of Medical Sciences in 2024. A stratified random sampling method was utilized. Data were collected using a demographic and occupational information checklist and a job hardiness scale. Data analysis was conducted employing ANOVA, independent t-tests, and regression analyses. A significance level of less than 0.05 was deemed statistically significant.
Findings: The average age of participants was 32.26 ± 6.34 years, with over two-thirds having bachelor's degrees and working rotating shifts. The average score for job hardiness was 44.67 ± 5.30. Results from multivariable regression indicated that educational status and a sufficient number of personnel accounted for 42% of the variance in job hardiness among EMTs.
Conclusion: Findings reveal that EMTs exhibit moderate to high job hardiness. Furthermore, adequate staffing levels and higher educational attainment positively correlated with increased job hardiness scores.

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.

So, the purpose of this study was to compare the effect of needle gauge on pain and anxiety during palatal infiltration anesthesia injection in children 4-8 years.
Methods: This triple-blind cross-over clinical trial study was performed on 60 children 4-8 years candidates for pulpotomy and SSC treatment of both maxillary first molar teeth. Based on the sequence of using 27- and 30-gauge needles, children were treated during 2 sessions. The anxiety level of children during palatal infiltration local anesthesia was measured using pulse rate (PR) and the pain level of patients was measured using SEM and FPR (objective and subjective criteria).
Results: Anxiety during palatal anesthesia injection with gauge 27 was higher than gauge 30 (treatment effect < 0.001). In subjective and objective criteria, the injection pain in the palatal mucosa with a 27-gauge needle was higher than 30-gauge needle (treatment effect < 0.001). There was no significant difference between earlier and later injection of palatal infiltration with different gauges during treatment sessions (P < 0.05) and according to 0.021 for the period effect, it can be said that the period of receiving two needle gauges had an effect on the average heart rate difference.
Conclusions: The pain of injection in the palatal mucosa with a 27-gauge needle is higher than with a 30-gauge needle, and the use of a 30-gauge needle in the palatal injection of children 4-8 years causes less discomfort than a 27-gauge needle.
