Abstract
Background & objectives: The “redox” state represents the oxidation/reduction potential within the cell in a way that more “redox” is the marker of health, while the more oxidized reflects predisposition to diseases. Different types of exercise training may change the thiol/disulfide ratio of redox couples such as glutathione and represent a shift in redox balance. This study was assessed the influence of high-intensity aerobic exercise on glutathione redox state in red blood cells in professional, recreational athletes and nonathletes.
Methods: Ten voluntary well trained (WT), moderately trained (MT) and untrained men subjectswere randomly selected for this semi-experimental study (mean ages of 21.10±1.72 21.70±1.88 and 20.10±1.44, respectively). Blood samples were collected before, immediately, 10 min and 30 min after acute aerobic exercise with 75%VO2max. The levels of reduced glutathione (GSH), oxidized glutathione (GSSG) and (GSH/GSSG) in red blood cells (RBCs) as well as serum levels of cortisol and creatine kinase (CK) were measured.
Results: The results showed reduction, elevation and no changes in RBCs GSH/GSSG ratio in UT, MT and WT groups, respectively. The lowest levels of GSH/GSSG ratio in RBCs and the highest one were detected in the WT and MT groups, respectively. The serum levels of cortisol and creatine kinase were increased following the exercise in three groups.
Conclusion: It is concluded that acute aerobic exercise with high intensity does not change redox balance in well trained subjects, however it is capable to shift redox balance towards more reducing environment in moderately trained subjects and also to more oxidizing one in untrained subjects.

Abstract
Background & objectives: Construction of new service centers including hospitals is expensive and requires optimal site selection for these centers so that all citizens benefit from its increased productivity. It can also help them lower their costs. This study investigates the optimal locations for construction of hospitals in Ardabil using GIS software.
Methods: This is an applied research which incorporates a descriptive-analytic methodology. The data is made up of 11 criteria; proximity to densely populated areas, proximity to green space, closeness to main thoroughfares, proximity to fire departments and distance from existing hospitals, industrial centers, slopes, learning centers, cemetery, military bases and from sport facilities. They were all weighted using analytic network process (ANP) model.
Results: After performing the necessary calculations and evaluations, the highest and lowest weight of criteria belonged to the proximity to densely populated areas (0.229) and distance from the cemetery (0.033), respectively. According to the criteria weights and overlapping of layers, the most and least favorable locations for the establishment of hospitals were identified.
Conclusion: Results of the classification showed the best location for construction of hospitals in Ardabil city based on four municipal regions. In region one it belongs to the 8th, 5th, 2nd, and 11th districts in region two districts of 6 and 7 which cover southeastern edge of the city, in region 3 districts of 1, 2, 6, 7, 8 and 10 which contain the western part of the city, and in region four it belongs to districts of 1, 2, 6, 7, 10 and 11 that encompass the blocks in the northern and north-western route of the city. These regions can be used for construction of new hospitals in order to improve people’s access to healthcare services.

Abstract
Background & objectives: There is a direct relationship between the presence of beneficial microbiota in the gut, development immune system functions and maintenance homeostasis. Hence, the consumption of foods or supplements with postbiotic components has been characterized as one of the most important strategies to modify the microbiome balance and improve the health status of the host. In this study, the concept of postbiotics and their clinical role in host health has been reviewed.
Methods: All articles related to the study subject were searched in the Scopus, PubMed/Medline, ISI Web of Knowledge, and Google Scholar database and studies that examined the effects of postbiotics on diseases were included.
Results: According to available evidences, postbiotics do not need the viability in comparison with their parent cells and they exert health effects like live probiotic cells. Also, their preparation and application in various delivery system is affordable, which this highlights the importance of postbiotics from technological, clinical and economic aspects. These compounds have biological activities including immunomodulation, antimicrobial, anti-inflammatory, anti-oxidant and anti-proliferation, and they can play an important role in modulating the immune system's performance, improving therapies and reducing their possible side-effects in some cases of gastrointestinal disorders and chronic diseases.
Conclusion: The postbiotics as a novel strategy can be used in a wide range of pharmaceutical products for the preventive therapy and improvement of the current therapeutic methods, as well as in food products to delay corruption, increase shelf life, and promote functional foods.

Abstract
Background & objectives: This research has been carried out in order to optimize technology development policies and reduce the costs of health technology development centers in universities of medical sciences. Identifying the influential factors in the growth of technology units helps the growth centers to more efficiently use the growth of knowledge-based companies and the development and progress of innovative entrepreneurs as a host environment for technology growth.
Methods: The current study is a qualitative research that was conducted by extracting qualitative data through semi-structured interviews with 31 managers of growth centers and managers of units located in growth centers and experts in the field of health entrepreneurship. It has been coded and categorized in three stages and the main and subcategories have been identified.
Results: The results show that for the growth of technology units in health technology growth centers, two basic variables of the growth center program and infrastructure have an effect on the efficiency of the centers and the growth of the units. This is despite the fact that according to the regional capacities of Type 3 medical sciences universities in the country, growth program factors have introduced more categories and less focus has been placed on infrastructure, so the growth plan is good. It can have a bigger share.
Conclusion: This research shows what categories are expected from the growth plan and infrastructures of health technology growth centers in few universities.

Abstract
Background & objective: The present research has investigated the impact of mental health on the behavioral inhibition and professional judgment of certified accountants with an emphasis on conflict theory.
Methods: In this descriptive-survey research, using Morgan's table, 306 official accountants working in the audit organization and audit institutes of Tehran in 1400, were selected as a sample by a simple random method. To collect data, standard questionnaires including Goldberg and Hiller's mental health, Goldstone and Parker's behavioral inhibition, Knapp, Gul et al.'s professional judgment, and Vahabzadeh's conflict were used. Structural equation model and SMART PLS3 software were used for data analysis.
Results: The research results indicate that the mental health of certified accountants has a negative effect on the conflict between them and the employer and a positive effect on behavioral inhibition and professional judgment of certified accountants. Their behavioral inhibition has a positive effect on professional judgment and a negative effect on the conflict between them and the managers of the receiving companies. Behavioral inhibition and professional judgment of certified accountants play a mediating role in influencing mental health on the conflict between them and the employer. Also, the professional judgment of certified accountants has a mediating role in influencing behavioral inhibition on the conflict between them and business owners.
Conclusion: According to the obtained results, people with higher mental health and stronger behavioral inhibition ability can make more professional judgments and reduce conflicts with others by using their abilities and mental health and managing their behavior. Resolving conflicts will be more successful.

Abstract
Background: Tooth decay directly and indirectly affects the national economy of some countries. These diseases reduce the number and productivity of the workforce. Medical expenses eat up savings and investments. All these factors reduce the earning power of individuals and households and affect the national economy, so an important part of the social and economic consequences of dental caries is the impact on savings at the household level and national income or gross domestic product at the national level.
Methods: The present study was descriptive, analytical and cross-sectional. The study sample was 260 6-year-old children and 260 adults who were referred to dental centers in 1401, and were randomly selected. The patients with tooth decay received services from the health and treatment centers of Ardabil city.
Results: The total cost of dental services related to tooth decay in 6-year-old children of Ardabil city was equal to 22543323 rials for one tooth, of which 94.23% of these costs are related to direct medical costs, 2.2% to indirect medical costs and 3.57% is related to non-medical indirect costs. The total cost of dental services related to tooth decay in the adult population of Ardabil city was estimated as 3,227,897 rials for one tooth, of which 95.93% of costs are direct medical costs, 2.43% of costs are direct non-medical costs, and 1.65% of costs are indirect costs.
Conclusion: Considering the high prevalence of tooth decay in 6-year-old children and adults in Ardabil city, its treatment imposes a significant part of the costs on Ardabil households, and the limited supply of dental services in the public health sector and the lack of insurance support in paying the costs have caused that families often pay for private services out of their own pockets.

Abstract
Background: Early childhood caries is a disease that affects the quality of life of a child and his overall health; it can interfere with the child's daily activities and growth process. This disease is affected by various factors such as diet, oral hygiene, social health factors and psychological issues. This study aimed to investigate the relationship between early childhood caries in children and the parents’ quality of life.
Methods: This cross-sectional descriptive study was conducted on 552 children aged 12 to 71 months in Ardabil city. The convenient sampling method was used and participants were patients who referred to Ardabil Dental Health Center. Dmft index (decayed, missing, and filled teeth) was assessed after examining the children. The World Health Organization questionnaire was used to evaluate the quality of life of the parents. The demographic information of children and parents was also determined. Statistical analysis included, kruskal-wallis, t-test and linear regression.
Results: The average score of the quality-of-life questionnaire was 66.42±17.91. No significant correlation was found between the mean quality of life of parents and dmft index. (p=0.916, r=0.008) A significant difference was observed between the child's dental caries and the father's age and education. (p<0.05) There was no significant difference in the mean dmft index, 5.32±0.5 in boys and 5.85±4.7 in girls. (p=0.459)
Conclusion: This study showed that the general quality of life of parents and its sub-branches such as the place where the child lives, the social and physical health of the parents are not directly related to early dental caries in children.
