This study aimed to determine the relationship between experiential avoidance and death anxiety, with the mediating role of meaning in life in elderly people living in nursing homes. The present descriptive-correlational study was conducted using structural equation modeling. The statistical population of this study was elderly people living in nursing homes in Rasht in 2024. 200 of them participated in this study using convenience sampling and responded to the Acceptance and Action Questionnaire (AAQ-II; Bond et al., 2007), the Death Anxiety Scale (DAS; Templer et al., 1971), and the Meaning of Life Questionnaire (MLQ; Steger et al., 2011). The data were analyzed using structural equation modeling. The findings showed that the proposed model had a good fit. Another finding showed that the direct effects of experiential avoidance and meaning in life on death anxiety were significant; also, the direct effect of experiential avoidance on meaning in life was significant (P<0.05); Also, the results of the bootstrap test showed that meaning in life had a mediating role in the relationship between experiential avoidance and death anxiety (P<0.05). The findings of this study indicate that experiential avoidance has a direct effect on death anxiety in the elderly through the mediating role of meaning in life.

In order to describe the biostratigraphy of the Late Cretaceous deposits of the Zagros basin in the southeast of the Lurestan area, a stratigraphic section of the Gurpi Formation selected in the Kabir-Kuh anticline (Sheikh-Makan section) and it was carefully sampled and studied. The thickness of the Gurpi Formation in this section is 179 meters, and in terms of lithology, it mainly consists of limestone, argillaceous limestone, marl, and shale, with two formal members of Seymareh and Imam-Hassan limestone. The lower and upper boundaries of the Gurpi Formation are conformable with Ilam and Pabdeh Formations, respectively, and the K/Pg boundary is located between the uppermost part of the shale of the Gurpi Formation (3.85 meters from the base of the Pabdeh Formation). Based on the planktonic foraminifera, 76 species belonging to 27 genera were identified, and 7 biozones belonging to the late Cretaceous, and 3 biozones belonging to the early Paleogene were introduced. Based on the identified biozones, the age of the Gurpi Formation is mid to late Early Campanian- Danian.

One of the services that has been significantly impacted by the ramifications of the COVID-19 pandemic is counseling and psychological services. Prior to the onset of this disease, individuals used to avail themselves of counseling and psychological services through in-person interactions. However, the current situation has faced a new reality, whereby the continuation of these services now relies on the utilization of remote communication tools. Consequently, both psychological education and services have undergone a notable transition towards non-face-to-face modalities. The objective of the current research was to examine the efficacy of online interventions for post-divorce adjustment on stress, anxiety, and quality of life among divorced individuals residing in Izeh in the year 2021. The present study utilized a quasi-experimental design with a pre-test and post-test approach, involving an intervention group and a control group. The target population for this research study included all divorced individuals residing in Izeh during the year 2021. The sample consisted of 24 female participants, divided into two groups of 12 individuals each (the first group receiving online interventions and the second group without any intervention) selected through purposive sampling. The intervention group was exposed to a 6-month online intervention program (based on the post-divorce adjustment online intervention protocol developed by Sadeghi, Goodarzi, and Karimi Sani, 2021) implemented through a mobile application, while the control group did not receive any interventions. The data collection instruments employed in this study encompassed the Cohen Perceived Stress Scale, the Beck Anxiety Inventory, and the Weir and Sherborn Quality of Life Questionnaire. The findings of the study demonstrated the efficacy of online interventions in promoting post-divorce adjustment by reducing perceived stress, alleviating anxiety, and enhancing overall quality of life among divorced individuals residing in Izeh. Consequently, this mobile application can be deemed a valuable tool during remote training sessions, aiding divorced individuals in their post-divorce adjustment journey.

This investigation aims to examine the available unconformity of the Late Alpine orogenic phases in the Lurestan sub-basin, with particular emphasis on the Baba Habib and Sultan anticlines. The disconformity occurs at the boundary between the Shahbazan and Asmari formations. Biostratigraphic examinations indicate that the Shahbazan Formation belonged to the middle to late Eocene, while the Asmari Formation is dated to the early Miocene. The investigated sections indicate prevalent marine deposits from the Late Eocene. According to research, the Late Alpine Orogenic phases had an exposure on this area of the Arabian Plate during the Late Eocene, as evidenced by the development of microkarst. Based on the amount of precipitation, the study area was located in a hot and humid climate zone.

An integrated analysis of subsurface data, encompassing seismic and well log information, serves as an effective approach for refining sequence stratigraphic interpretations and enhancing the understanding of oil fields. This method elucidates the connections between sedimentary sequences, facies, and reservoir characteristics, facilitating more precise predictions of facies distribution and the identification of hydrocarbon reservoirs. In this study, the deposits of the Kazhdumi Formation in a field located in the northwestern Persian Gulf were analyzed across three wells. To achieve a more detailed evaluation of the Kazhdumi Formation, seismic data were calibrated with well data using check shots. Following this calibration, seismic data interpretation was conducted according to sequence stratigraphy principles, focusing on seismic reflector terminations on seismic sections to delineate the sequence boundaries and elements within the Kazhdumi sequence. Seismic analysis revealed a single seismic sequence within the Kazhdumi Formation in the studied field. This sequence comprises several components: the base of the Dariyan Formation (lower sequence boundary), the base of the Maddud Formation (upper sequence boundary), the Borgun B Formation (lowstand systems tract), the Borgun A Formation (transgressive systems tract), the Dair limestone (overlying the maximum flooding surface), and the upper Kazhdumi along with a portion of the Madud member of the Sarvak Formation (highstand systems tract). The Kazhdumi sequence was mapped and interpreted on 2D seismic sections within the study field and adjacent areas. Subsequently, subsurface isochron maps were created by interpolating points between 2D seismic lines.

Understanding adipogenesis, the process of adipocyte development, may provide new insights to treat type II diabetes and related metabolic diseases. The present study investigates the effect of eight weeks of moderate-intensity continuous training and L-carnitine supplementation on Wnt10b protein expression related to visceral adipose tissue adipogenesis in streptozotocin (STZ)-induced diabetes in larg rats.

In an experimental clinical-intervention study, 50 large laboratory mice were divided into 5 equal groups of control (C), diabetic (D), supplemental diabetic (D + LC), diabetic with exercise (D + T), supplemental diabetic with exercise (D + LC + T). The training program consisted of three times a week for 30 minutes on a treadmill at a speed of 15 meters per minute. Five days a week, 30 mg/kg of L-carnitine was given through drinking water. Expression of Wnt10b protein at visceral fat was measured by western blot method. Data analysis was performed with one-way analysis of variance and Tukey's post hoc tests at a significant level (P< 0.05).

The results showed that the expression of Wnt10b protein, the Lipolysis inhibitory protein, in both (D+LC+T) groups and (D+T) decreased significantly (P< 0.001).

According to the results, it seems that MICT exercise with L-carnitine supplement and alone is more effective in decreasing the expression of protein associated with adipogenesis in visceral fat. However, a clear statement requires further research in this area.

Technological changes lead to the creation of new challenges and opportunities for various industries. The inability of companies to adapt their business model to these changes may even lead to their exit from the market. Therefore, it is very important to accurately evaluate the consequences of new technologies on the business models of various industries. Blockchain has been one of the most important technology trends in recent years. One of the industries that many experts believe will take major changes from blockchain technology is the banking industry. Considering the revolutionary impact that blockchain technology can have on the banking industry. Investigating the impact of this technology on the business model of the banking industry, which represents how to create, provide and acquire value in this industry, will be very important. The general purpose of this article is to present the strategic value creation model of blockchain technology in financial and banking fields. This research is applied in terms of purpose and exploratory in nature. This research was done in three parts, in the first part, the dimensions, components and indicators of the model were prepared from the metacombination approach. In the next step, fuzzy Delphi method was used to identify, evaluate, screen and localize the model. In the final part, Denep technique was used to analyze relationships and their effects. The first stage community including 73 articles out of 849 articles (between 1395 and 1402 for domestic articles and 2016 to 2023 for foreign articles) were selected by systematic review and coded by content analysis method. In the second stage; 7 dimensions, 23 components and 102 indicators were validated and localized with the help of 17 experts, and in the final stage, dimensions and components were prioritized with the help of experts and the final model was extracted. The results of this research stated that the use of blockchain technology can create value for financial and banking businesses in terms of innovation and technology, transparency, security, quality, speed, business models and cooperation, and give them strategic capabilities. As a result, due to the fact that blockchain technology has not found a special place in the banking system of our country, there is a need for decision-making managers to pay attention to this area.

Studies have shown that individuals who experience divorce often face challenges in adjusting to their new circumstances and may encounter difficulties in managing emotions, coping with stress, and maintaining healthy relationships. Online interventions have emerged as a novel approach to supporting individuals in the post-divorce period. These interventions typically provide interactive resources and tools through digital platforms, offering guidance, support, and skill-building exercises to assist individuals in navigating the challenges of divorce and enhancing their psychological well-being. However, there is a gap in the existing research regarding the design and validation of online intervention protocols, particularly tailored to post-divorce adjustment.

The aim of the present study was to design and validate an online intervention protocol for post-divorce adjustment.

This research was conducted using a qualitative method (thematic analysis) through semi-structured interviews, with the target population consisting of all family experts in Khuzestan province. The research sample was selected using purposive sampling method. The criteria for selecting individuals included holding a doctoral degree in counseling or psychology and having a minimum of 5 years of therapeutic experience with couples and families. The interview data were analyzed in three stages: open coding, axial coding, and selective coding, using MAXQDA software.

In the developed protocol, interventions were categorized into three sections: self, children, and emotions and stress. The self-section comprised five topics: stress and anxiety management, anger management, resilience, communication with the ex-spouse, and remarriage. The children section included five topics: investing in children's future, interactions regarding parenting, interactions with families, remarriage, and interactions with children during holidays and celebrations. The emotions and stress section encompassed two topics: forgiving the ex-spouse and accepting divorce and reality.

Considering the positive validation results of the designed protocol, its utilization for post-divorce adjustment during contagious diseases that require non-face-to-face services will aid in the adjustment of these individuals. It is recommended that mental health professionals take steps to expand its implementation in the field of mental health.

Adipogenesis is a dynamic process that leads to the phenotype of mature fat cells and plays a significant role in obesity and diabetes. The present study investigates the effect of Eight –Weeks of High-Intensity Interval Training (HIIT) and L -carnitine Consumption on the expression of BMP7 protein in visceral adipose tissue in diabetic rats.

In an experimental clinical-intervention study, 50  male Wistar rats were divided into 5 equal groups of control (C), diabetic (D), supplemental diabetic (D + LC), diabetic with exercise (D + T), supplement and exercise (D + LC + T). The training program consisted of eight weeks, 5 sessions per week (6 to 12 2-minute sessions with an intensity of 85-90% of the maximum speed). The subjects received 30 mg/kg body weight L-carnitine through drinking water. Visceral fat was extracted and the expression level of BMP7 protein was assessed using Western Blotting. Data analysis was performed by one-way ANOVA and Tukey post hoc test at a significant level of (P< 0.05).

The results showed that the expression of BMP7, the adipogenesis stimulating protein, in (D + T) and (D + LC + T) groups increased significantly (P< 0.001).

According to the results, it seems that HIIT exercise alone and with L-carnitine Consumption is more effective in the expression of protein associated with adipogenesis expression in visceral fat. However, a clear statement requires further research in this area.

In order to study the biostratigraphy of the Gurpi Formation in the Fars area, a stratigraphic section is selected and sampled in the Sarbalesh anticline. The thickness of the Gurpi Formation in this section is 346.3 meters and its main lithology includes argillaceous limestone and shale. The lower boundary with the Sarvak Formation indicates a disconformity with dissolution holes and iron oxide bearing fragments, and its upper boundary with the Pabdeh Formation indicates a disconformity with a 30 cm thick key horizon containing phosphate nodules and manganese oxide traces. In this study, by identifying 66 species belonging to 22 genera of planktonic foraminifera, 9 biozones were identified and introduced based on the Tethys standard biozonation of Premoli Silva and Verga (2004). The age of the Gurpi Formation based on identified biozones is determined from the early Santonian to the late Maastrichtian. The K/Pg boundary is located at the end of the key horizon containing phosphate nodules and correlates with the lithostratigraphic boundary of the Gurpi and Pabdeh formations.

Subsequently, 7 dimensions, 23 components, and 102 indicators were validated and localized with the assistance of 17 experts. In the final stage, these dimensions and components were prioritized with expert input, leading to the extraction of the final framework. The results indicate that fintech-driven blockchain technology enhances value creation in the dimensions of innovation and technology, transparency, security, quality, speed, business models, and collaboration, providing strategic capabilities to financial and banking businesses.

Research has shown that the tendency to addiction is influenced by personality characteristics and through mediating variables including emotional well-being as emotional and cognition values and mental experience of positive emotions and life satisfaction. but there is a research gap in the researched population.

The present study was conducted with the aim of investigating structural equation modeling of the relationship between personality traits and addiction tendencies in adolescents: the mediating role of emotional well-being.

This research was of a descriptive-correlation type with structural equations. The statistical population of the present study was all male students of the second secondary level of public high schools in Rasht city in the academic year of 2019-2019, numbering 16451 students. In order to determine the sample size, the number of 300 male students was selected multi stage cluster sampling method and completed the five-factor questionnaires of Neo personality of Costa & McCrae (1970), emotional well-being scale of Keyes and Magyarmo (2003) and Farjad addiction tendency questionnaire (2006) were completed. Data were analyzed with Pearson correlation coefficient, path analysis and structural equations and with spss 19 and amos 22 software.

The results showed that the direct effect of extroversion (0.21) and emotional irritation (0.22) on addiction tendency is positive and significant (P < 0.05). Also, the indirect effect of psychological irritation through emotional well-being on addiction tendency was significant.

According to the obtained results, it can be said that the personality traits of extroversion and neuroticism directly and neuroticism indirectly had an effect on the level of addiction tendency, Therefore, focusing on the results of the current research, can be to reduce the tendency to addiction in adolescents.

This research was conducted with the aim of investigating the structural relationship of marital conflicts, alexithymia, anxiety sensitivity and sexual dissatisfaction in married female students of University of Guilan.
The present research method was descriptive and correlational. A sample of 175 people was selected from the community of married female student in University of Guilan. To collect data, Toronto alexithymia TAS-20, anxiety sensitivity ASI-R, marital conflicts MCQ and sexual satisfaction ISS questionnaires were used. Data analysis was done using structural equation analysis method through Amos software environment.

All analyzes were performed using SPSS26 and AMOS24 software. Bootstrap method was used to analyze the intermediate relationships in MACRO Preacher and Hayes (2008). The results showed that self-control has a direct and significant effect on emotional well-being (p<0/008). Also, the direct effect of self-control on self-compassion was significant (p<0/001), but the direct effect of self-control on emotion regulation was not significant (p> 0/05). The indirect effect of self-control on emotional well-being due to self-compassion was significant (p<0/001), but the indirect effect of self-control on emotional well-being wasnot significant due to emotion regulation (p> 0/05).The results of the research have practical implications for health professionals and psychologists and it can be concluded that self-control through self-compassion has an effect on the emotional well-being of cancer patients.

Anabolism has a major contribution in increasing proteolysis and muscle mass of athletes. This study was done to investigate the impact of the acute use of different doses of glutamine supplementation following exhaustive physical activity on cortisol and testosterone levels in young male athletes. 

Following a semi-experimental design, 24 male athletes with a mean age of 22.35±1.79 years were randomly selected and divided into two intervention groups (glutamine; 0.1 and 0.6 gr/kg body weight (BW) and a placebo group (10 g of dextrin dissolved in 500 mL water), each with eight subjects. Serum levels of cortisol and testosterone were measured immediately, 90 minutes, and 24 hours following the test. Data analysis was done using paired t-test and repeated measures analysis of variance at P<0.05.

Bruce protocol significantly increased cortisol levels immediately after physical activity (P<0.05). Cortisol levels significantly decreased in subjects receiving glutamine at 0.6 g/kg Bw (P=0.03) and 0.1 g/kg BW (P=0.02) 90 minutes and 24 hours following the protocol. Meanwhile, testosterone levels only increased in cases who received glutamine at 0.6 g/kg BW 24 hours following the protocol (P=0.02).

According to the results of this study, taking a glutamine supplement at a dose of 0.6 g/kg body weight after exhausting activities is probably effective in maintaining an anabolic profile.

Over the past few decades, the phenomenon of addiction has increased all over the world for various reasons. The aim of this study was to investigate structural modeling of the relationship between spiritual health with addiction tendency in adolescents with the mediating role of emotional well-being.

This research was descriptive-correlation based on the model of structural equations. The statistical population of this research included all the male students of the second secondary level of public high schools in Rasht City in the year of 2021. From this community, 300 qualified volunteers have been selected for the study by the multistage cluster sampling method. Three standard questionnaires, including Paloutzian and Ellison Spiritual Well-Being Scale (1982), Keyes and Magyar-Moe subjective well-being (2003), and Mousavi et al Addiction Tendency Scale (2008) were used for data collection.

This research confirms the mediating role of emotional well-being in the relationship between spiritual health and addiction tendency. It is hoped that families and guardian organizations will benefit from the results of this research.

The effects of exercise and sirtuin1 on inflammatory markers may be a therapeutic target for type 2 diabetes. This study aimed to determine the effect of 8 weeks of combined training along with supplemental consumption of Mulberry Leaf Extract on serum sirtuin1 levels and insulin resistance index in elderly men with type 2 diabetes. In this semi-experimental clinical study 40 elderly men with diabetes (age: 67.07 ± 1.50) were randomly divided into five groups: control, placebo, extract, training, and extract + training. Aerobic training (10 to 30 minutes with an intensity of 50 to 70% of maximum heart rate) and resistance training (30 to 40 minutes, 8 to 12 repetitions per movement, between 40 to 80% of a maximum repetition) were performed. Mulberry Leaf Extract was prescribed to the subjects in three doses (each dose, 2 capsules of 500 grams). The variables were measured 48 hours before and after the test. The training, extract, and training +extract groups, a significant decrease in insulin resistance index and a significant increase in sirtuin1 level were observed (P<0.05). results between the groups showed a significant difference in the index of insulin resistance (P=0.001, F=60.70) and sirtuin1 (P=0.001, F=15.38), and these changes in the extract + training group compared to training and extract groups are larger (P<0.05). It seems that prescribing a combined training along with the consumption of Mulberry Leaf Extract the elderly with type 2 diabetes can have the greatest effect in improving insulin resistance and sirtuin1 in the elderly with diabetes.

Probing in Ahl al-Bayt Hadiths reveals several cognitional, moral, social and emotional aspects of “faith” apart from its “ideological” aspect and also shows its potential of incensement. On the other hand, James Fowler’s significant and psychological theory of “stages of faith growth” depicts the essence of “faith growth” in “increasing and enhancement of a collection of cognitional, social, moral and emotional capabilities” during the lifetime. The base of this study is a comparison between the mentioned cognitional theory with the concept of faith increasing in Hadiths. According to hadiths, increasing in faith means “realization, consolidation and enhancement in cognitional, emotional, moral and social indices of faith in human beings”. Fowler also believes that “the orientation of faith growth is towards more progressed levels of cognition, integrity, meaning making and interpersonal relationships”. Although, in his approach human beings lack a proper and complete and absolute exemplary in faith.

The concern about the quality of life of the elderly living in resident at home and nursing homes has been one of the controversial issues. Some studies believe that if the mental health of the elderly is provided and a suitable atmosphere is created in the nursing homes, better health care and treatment can be provided to the elderly and their life expectancy can be increased; But on the other hand, some studies believe that caring for the elderly at home and with other family members can have an effective role on their psychological health; so that the results of some studies indicate that this group of elderly people have a higher life expectancy; But on the other hand, it can threaten their physical health and make them prone to other chronic diseases and malnutrition. Admission to a nursing home evokes emotional consequences, including feelings of rejection, psychological tension, depression, instability, loss of home and the chance to contact family and friends. Research shows that the living environment of the elderly plays a very important role in their psychological health. It has been shown in various researches that the level of quality of life and mental health, happiness and social health in the elderly living in nursing homes is lower than that of the elderly living at home; Based on this, it can be concluded that there is a relationship between living in a nursing home and the psychological state of the elderly, but it cannot be said with certainty that the low mental health of the elderly indicates living in a nursing home; Because some studies have shown that the diseases and disabilities of elderly people living in nursing homes are more than other elderly people, and disabilities lead them to care centers; Maybe this factor also has an effective role in reducing their mental health. Based on this, the implementation of a comparative study in the elderly with high performance and control of physical disabilities will clarify the role of living in a nursing home in the state of mental health of the elderly, which is addressed in the present study. Also, some studies indicate that the stay of the elderly in the nursing home is associated with the feeling of exclusion and their feeling of loneliness plays an effective role. Also, the research showed that the elderly living in the nursing home experienced a feeling of insecurity and rejection and described their transition from home to the nursing home as painful; In other words, living in a nursing home can have an effective role in reducing the mental health of the elderly. Elderly people who have a high level of rejection feel that they are of no use to themselves and those around them and cannot be effective; Also, the results of this study showed that the feeling of rejection, due to its high relationship with social incompetence, has an effective role in increasing depression symptoms in these elderly people; Based on this, it can be concluded that living in a nursing home, rejection and depression are closely related. In this regard, the results of some studies show that the elderly living in nursing homes have far more symptoms of depression, anxiety and stress and report less satisfaction with life. Nowadays, due to the increase in the number of elderly people and the shrinking of families, caring for the elderly is a very important issue, and detailed and comprehensive programs for the care of this sensitive age group should be provided by conducting field research and formulating detailed care policies. Compared to younger people, older people with depression usually have multiple co-occurring medical and cognitive disorders, and depression that occurs in older patients is often underdiagnosed or undertreated. Also, previous studies have shown that inactivity and disability are factors affecting the feeling of exclusion of the elderly; which, if accompanied by family rejection, can lead to an increase in psychological distress in the elderly. Considering the importance of this topic, the present study compared the perception of rejection and depression symptoms in elderly people living in nursing homes and resident at home.

The current research was descriptive and based on causal-comparative method. The statistical population of this research includes two groups of elderly people in Rasht city in 2020 who were living in nursing homes or living with their families. The sample size was calculated using G*Power software. From each group, 120 elderly people participated in a targeted manner and answered the Perceived Rejection Scale: PRS and the Geriatric Depression Scale: GDS-15. For both groups, the age gap is between 65 and 90 years, having minimum physical health to communicate and answer the questions of the questionnaire, not suffering from cognitive impairment diseases such as (Alzheimer, stroke and dementia), not being engaged in economic activity. And retirement from governmental and non-governmental institutions and having informed consent and willingness to participate in the research were considered as entry criteria. Also, failure to answer at least 10% of the questionnaire questions, fatigue and unwillingness to complete the questionnaire were considered as exit criteria. Data analysis was performed using SPSS-24 statistical software and multivariate analysis of variance.

The results of multivariate analysis of variance showed that the perception of rejection (F = 14.25, P = 0.001) and depressive syndrome (F = 17.280, P = 0.001) in the elderly living in nursing homes were significantly higher than the elderly were in the control group (P <0.001).

Overall, the results of this study showed that the perception of rejection and depression symptoms in elderly people living in nursing homes is more than that of elderly people living at home; But this difference cannot be attributed to the presence of the elderly in the nursing home. But in general, it can be concluded that elderly people living in nursing homes are more in need of appropriate interventions and educational programs to reduce the feeling of rejection and depression symptoms than the elderly people living at home. Therefore, it is suggested to provide educational and therapeutic programs to improve the psychological condition of these elderly people.

Quick and accurate assessment of cardiorespiratory capacity is very important in research and exercise conditions. Therefore, the design and evaluation of cheap, light, and portable devices are worthy of consideration. FFThis study investigated the reliability of endurance performance indices in Futsal (EPIF) during the implementation of two selected field tests (FIET = Futsal intermittent endurance test and TCAR = Carminatti test). 23 futsal players with playing experience of 7.2 ± 2.1 years, an average age of19.1 ± 3.07 years, and a body mass index of 21.20 ± 1.04 kg/m2, were randomly selected. They first voluntarily performed the FIET test and then the TCAR test with an interval of 3 days. To evaluate the validity and reliability of the TCAR field test, the researchers used Pearson's correlation coefficient and intra-class intragroup correlation (ICC), respectively. A significant correlation was found between the physiological variable of final heart rate (HR) and the HR delta of running activity in the FIET test, with VO2 max using the standard method. The reliability of the FIET test was reported at an excellent level (p < 0.001, ICC = 0.912-0.939). Also, after the field tests, the HR delta was reported as a suitable predictive factor for estimating the VO2 max of young futsal players (p = 0.020, SEE = 4.051, R2 = 0.512). The findings show the high reliability and validity of the TCAR field test with the EPIF device. Therefore, the design and construction of this native device and its use for coaches at the club and national levels are worthy for evaluating the athletic endurance of futsal players.

The fetus is the source of many stem cells that have great potential in repairing and regenerating different tissues and can differentiate into various types of cells including osteoblast and adipocyte. However, less attention has been paid to the isolation and differentiation ability of these cells in the culture medium. Therefore, the present study aimed to determine the isolation method, proliferation, and differentiation of fetal mesenchymal stem cells (fMSCs) derived from rat fetuses.

In this experimental study, fMSCs were isolated from 15-day-old rat fetuses using trypsin enzymatic digestion and they were cultured up to 3th passage. Then, the fMSCs were characterized by flow cytometry and differentiated into osteoblast and adipocyte cells. Cell proliferation and expression of osteogenesis- and adipogenesis-related genes were investigated in differentiated cells.

Cell surface markers of fMSCs at passage 3 were positive for CD105 and CD90 and negative for CD45 and CD34. These cells exhibited a fibroblast-like morphology. These cells had calcium deposition in osteogenic differentiation and accumulation of fat droplets in adipogenic differentiation. The osteogenesis-related genes including osteonectin, ALP, BMP-6, and Runx-2, and adipogenesis-related genes such as PPARγ and CREBBP were expressed in osteogenic and adipogenic differentiation cultures, respectively.

According to the findings of the present study, it seems that mesenchymal stem cells isolated from rat fetuses have the potential to proliferate and differentiate into osteoblast or adipogenic lineages.

Despite the relative comfort and welfare today’s modern technology has brought to humankind, it has also been the basis for the emergence of risks and threats. These risks and risk factors should be assessed and controlled using systematic risk assessment and management methods. Numerous techniques and methods have been developed to analyze risks, each of which has its own strengths and weaknesses. One of the system risk analysis techniques, which is among qualitative techniques and identifies and analyzes system risks inductively, is the functional hazard analysis (FuHA) technique. The present study aims to identify and control risks that occur due to technical defects or system dysfunctions and can lead to an unpleasant event, as occurred in an industrial unit in 2016.

In this cross-sectional analytical study, the functional risks of an industrial unit were analyzed using the FuHA technique. By implementing the FuHA technique in the investigated industrial unit, 17 functional defects were identified.

In general, according to the level of severity of different consequences caused by the identified defects, 60 functional risks were identified, of which 7 cases (11.67%) were assessed as unacceptable, 17 cases (28.33%) as unfavorable, and 36 cases (60%) as acceptable but needing revision.

The results of this study showed that the FuHA technique had a favorable ability to identify and analyze system and subsystem functional risks, especially software subsystems.

Fibroblast growth factor 21 is proposed as a therapeutic target for type 2 diabetes. The aim of this study was the effect of 8 weeks of combined exercises along with the consuming of mulberry leaf extract on the serum levels of glucose, insulin and fibroblast growth factor 21, in elderly men with type 2 diabetes.

In this semi-experimental study, 40 elderly people (age: 67.07 ± 1.50) living in Ardabil province with type 2 diabetes after obtaining written consent were randomly divided into five control groups (8 people) and a placebo group (8 people). The extract group (8 people), the training group (8 people) and the extract + training group (8 people) were divided. The exercises were performed in three sessions for eight weeks. 3000 mg of blackberry leaf extract was prescribed daily. Glucose, insulin and FGF21 values were measured before the intervention and 48 hours after the last training session. Paired t-test and analysis of covariance were used at a significance level of P < 0.05.

A significant decrease in blood glucose levels (161.22 ± 4.91), insulin (9.91 ± 0.80) and a significant increase in FGF21 levels (66.61 ± 7.06) were observed in the training + extract group (P < 0.05). A significant difference was observed in the levels of glucose (P = 0.001), insulin (P = 0.003) and FGF21 (P = 0.001) between the groups, and these changes were greater in the extract + exercise group than the training and extract groups.

Combined exercises along with the consuming of Mulberry leaf extract can improve blood glucose, insulin and FGF21 in the elderly with type 2 diabetes.

Fetuin-A and Fetuin B have effective role in age-related metabolic disorders such as type 2 diabetes. This study aimed to determine the effect of 8 weeks combined training along with consumption of Mulberry Leaf Extract on serum Fetuin-A and Fetuin B levels in elderly men with type 2 diabetes

In this case-control study, 40 elderly people with diabetes were randomly divided into five groups of: control (n = 8), placebo (n = 8), extract (n= 8), training (n=8), and extract + training (n = 8). Training was done for eight weeks and three sessions of 90 minutes each. 3000 ml of Mulberry Leaf Extract per day was prescribed along with three main meals. Fetuin A and Fetuin B levels were measured before the intervention and 48 hours after the last training session. Data were analyzed using SPSS version 23 statistical software at a significance level of P<0.05 and using paired t-test and analysis of covariance.

In the training, extract, and training+extract groups, a significant decrease in fetuin-A and fetuin B levels was observed (P<0.05). The extract + training group shows a larger decrease in Fetuin A (6.02%) and Fetoin B (5.09%) compared to the pre-test. Between groups analyses showed significant differences in the levels of Fetuin (P=0.002) and Fetuin B (P=0.001), and these changes were greater in the extract + training group than them in the training and extract groups.

The results of this research showed that prescribing a combined exercise program along with the consumption of Mulberry Leaf Extract in diabetic elderly can possibly have a positive effect on Fetoin A, Fetoin B levels.

The aim of this study was to investigate the mediating role of emotional schemas in the relationship between attachment styles and childhood trauma with a tendency to extramarital relationships. The research method was descriptive-correlational. The statistical population of the present study consisted of all married students of Guilan University in the academic year 1399-1400, which included 2061 people, and 246 of them entered the study by the available sampling method. Research instruments included the Revised Adult Attachment Scale (RAAS, Collins and Reid, 1996), abbreviated childhood trauma Questionnaire (CTQ, Bernstein et al, 2003), Attitudes Towards Extramarital Relationships Scale (ATERS, Watley, 2006), and Emotional Schemas Scale (LESS, Leahy, 2002). A structural equation modeling method in the form of path analysis was used for data analysis. The results showed that the proposed research model has a good fit. Bootstrap results also showed that the indirect path of secure attachment style with a tendency towards extramarital relationships through adaptive and maladaptive emotional schemas was significant (P<0/05). The indirect path of ambivalent-anxious attachment style with a tendency towards extramarital relationships through adaptive and maladaptive emotional schemas was significant (P<0/01). The indirect path of childhood trauma with a tendency towards extramarital relationships through adaptive emotional schemas was significant (P<0/05). From the above findings, it can be concluded that emotional schemas play a mediating role between attachment styles and childhood trauma with a tendency towards extramarital relationships,  and it is necessary to pay attention to these factors in prevention and counseling programs.
