Abstract
Introduction: Pain relief has been received the highest level of medical attempts continuously but still many patients suffer from it. Narcotics' side-effects have led investigators to apply other techniques for controling acute postoperative pain to reduce narcotics requirements. Recently, some concepts have been presented implying that Metoclopramide does have analgesic effects and this led us to conduct the present study in order to determine Metoclopramide's effect on alleviating pain after cesarean section. Materials and Methods: In this clinical trial, 80 patients who were candidates of elective cesarean section were studied in two groups. 10 minutes before the cesarean section's ending time, the control group was given 25 mg Pethidine accompanied by 10 mg Metoclopramide and control group 25 mg Pethidine and distilled water. Then when patients were conscious after cesarean section, for a period of 6 hours received after-care for their vital signs and side-effects of prescribed drugs. Their pain score (VAS) and nausea rate was measured and if necessary, Pethidine was injected with certain dose. Injection time for first dose of Pethidine and its required amount were recorded in a checklist within first 6 hours after cesarean section. Data was analyzed using ANOVA and T tests. Results: Prescription of Metoclopramide inhaunced analgesic effect of narcotics and a meaningful decrease was found in pain score (p=0.002) and nausea rate (p<0.005). Injection time for the first dose of Pethidine was also prolonged in the group who received Metoclopramide compared to control group (p=0.019) and an obvious decrease was occurred in received Pethidine's amount within the first hours after cesarean section (p<0.005). Drugs side-effects were not found in patients. Conclusion: The results indicate that use of Metoclopramide accompanied by Pethidine in ending time of cesarean section, does have considerable effects in controlling acute pain after surgery and increasing analgesic effect of narcotic drugs. Therefore, use of Metoclopramide as a proper supplement drug with low side-effects is recommended.

Abstract
Background: Albizzia lebbeck is used for the treatment of diarrhea and dysentery. In this study the efficacy of hydro-ethanolic extract of this plant on enteric gram-negative and aerobic gram-positive bacillis was determined. Materials and Methods: In this experimental-clinical trial, cold maceration method by ethanol was used for extraction of Albizzia lebbeck fruit, seed, flower and leaves. Then its polyphenolic components were separated by ethyl acetate. After concentrating the different extracts through disk diffusion and tube dilution, the effect of minimal inhibitory concentration (MIC) and minimal bacteriocidal concentration (MBC) of their antibacterial component on shigella dysenteriae, proteus mirabilis, escherchia coli, bacillus cereus and bacillus anthracis were evaluated. Also, the antibacterial effects of Albizzia lebbeck extracts together and in combination with some antibiotics, were compared through variance analysis. Results: Different extracts of Albizzia lebbeck just had similar and positive effects on shigella dysenteriae, bacillus cereus, and bacillus anthracis. However, the hydro-ethanolic fruit extract was more effective than the falavnoid fruit, flower and leave extracts. MIC and MBC results for antibacterial material on the three aforementioned bacterias were 0.125 and 0.25 gram/ml, respectively while the effects of the polyphenolic components of this plant's fruit were similar to its hydro-ethanolic extracts. Conclusion: Through the identification of different components of Albizzia lebbeck and the attainment of new formulations of these components, the grounds will be provided for its application on treatment of patients with inflammatory diseases and asthma, and on improvement of their immune system.

Abstract
Background: All-trans retinoic acid(RA), an active metabolite of vitamin A, is widely used to induce cell differentiation. It has significant effects on growth and proliferation of epithelial cells. It also causes cell cycle arrest in G0/G1 phase and induces the apoptosis. cisplatin, a chemotherapy compound that cross-linking to DNA, and leads to apoptosis, it is commonly used for treatment of ovarian, head and neck, esophageal, gastric cancers and melanoma. Recent studies showed that RA enhances cytotoxic effects of cisplatin on melanoma and ovarian cancer. Our literature review showed that there is no previous study on the effect of RA in combination with cisplatin on esophageal cancer, hence current study conducted to investigate such combination treatment on esophageal derived cell, KYSE-30.
Materials and Methods: KYSE30 cell line was cultured in presence of different concentration of RA alone and in combination with cisplatin. Then, cell death was investigated by colonogenic assay and acridine orange/ ethedium bromide staining.
Results: The results showed that RA concentrations &ge15µM cause differentiation of KYSE30 to squamous cell morphology, while lower concentrations decreases the colony formation (p&le0.05). These effects were also observed in combination with cisplatin and RA. The best effects on cell death were observed in 10 µM of RA of combination with 5 and 10 µg/ml of cisplatin.
Conclusion: The results suggest that low concentration of RA in combination with cisplatin are more effective than cisplatin alone in terms of apoptosis and necrosis of esophageal cancer, KYSE-30.

Abstract
Background: Diabetic retinopathy (DR) is a severe complication of diabetes and the leading cause of blindness among working adults worldwide. Chronic extra cellular hyperglycemia in diabetes stimulates reaction oxygen species (ROS) production and increase oxidative stress. Glutathion S- transferases (GSTs) enzymes have been shown to protect human from reactive oxygen compounds damage. The aim of the present study was to investigate whether the genetic polymorphism of GSTP1 is associated with DR.
Materials and Methods: This case–control study, included 70 patients with DR and 70 healthy volunteers. Genomic DNA was extracted from peripheral blood leukocytes. Genotypes were determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Statistical analysis was performed using the MedCalc program for Windows version 12.
Results: The prevalence of genotype frequencies of the GSTP1 Ile/Ile and Ile/Val were 71.42% and 28.57% respectively, in DR subject, whiles in healthy volunteers were 78.58% and 21.42%, respectively. Statistical analysis has not emerged significant difference from the comparison of either genotype (&Rho>0.05).
Conclusion: There was no evidence that GSTP1 variants were associated with DR in studied population. Further research is required to clarify role of GSTP1 in DR.

Abstract
Background: Diabetic retinopathy (DR) is the complication of diabetes mellitus (DM) and causes blindness among adults. Chronic extra cellular hyperglycemia in diabetes stimulates reaction oxygen species ROS production and increases oxidative stress. GPX-1 that was coded by GPX-1 gene is a key enzyme in protecting vessels against oxidative stress. The aim of this study was to evaluate the association of GPX-1 gene Pro 198 Leu polymorphism in patients with diabetic retinopathy.
Materials and Methods: In this case-control study, 160 blood samples of participants including 80 patients with diabetic retinopathy and 80 healthy individual were tested. Genotyping of GPX-1 gene was determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) by ApaI enzyme. Data analysis was performed using MedCalc (12.1) program.
Results: The genotype frequencies of the GPX-1 in DR patients for Leu/Leu, Leu/Pro, Pro/Pro were 10%, 62.5% and 27.5%, respectively, while for the control groups were 10%, 70% and 20%, respectively.In ohter words, Ile/Pro heterozygote was the most frequent genotype in patients and controls. According to the results of this study, there was not significant difference between patients with diabetic retinopathy and controls(p=0.52).
Conclusion: It is concluded that GPX-1 gene Pro 198 Leu polymorphism is not associated with DR. Further research is required to clarify the role of GPX-1 gene in DR in Rasht population along higher sample size.

Abstract
Background: ALS is a progressive neuro-muscular disease, which is characterized by motor neuron loss in the Central Nervous System (CNS) and Peripheral Nervous System (PNS). Up to now, no accurate clinical method for diagnosis of the disease have been provided. In most cases, ALS patients are unable to walk normally due to abnormalities in the nervous system. For this reason, one of the most appropriate methods in the diagnosis of ALS from other neurological diseases or from healthy volunteers is the gait motor signal analysis.
Materials and Methods: In this study, gait signals available in Physionet database have been used. The database consists of 13 patients with ALS (ALS1, ALS2, …, ALS13) and 16 normal subjects (CO1, CO2, …, CO16). The patients participating in this study had no history of any psychiatric disorders and did not use any assistive device for walking, like wheelchair. The power spectrum of stride, swing, and stance of normal subjects and patients was computed for both left and right legs. To provide appropriate inputs for the classifier, the frequency band of the power spectrum of all signals was divided into eight equal parts. The area of all regions was computed. Three frequency band of the lower range of power spectra selected as inputs of the classifier.
Results: In this study, power spectra, as frequency attributes, were used to explore probable differences of time series in both patients and healthy subjects.
Conclusion: Artificial Neural Network was used to classify normal and ALS groups with the accuracy of 83% for the test data set. It seems that the present algorithm can be used in discriminating patients from normal subjects in the early stages of the disease.

Abstract
Background: Irisin is a new myokine that exerts its positive effects via increasing energy expenditure. The purpose of this study was to determine the effect of submaximal aerobic training on serum irisin level and irisin-related insulin-resistance change in obese men.
Materials and Methods: In this study, 26 obese men were selected as statistical sample and they were divided into experimental groups. Former group (13 men) consisted of subjects who carried out exercise training with 50-60 percent of maximum max heart rate for 10 continuous weeks (3 sessions per week for 30 to 45 minutes in each session). Later group was consisted of subjects who do not carried out exercise training. After the interventions of study, irisin serum levels, insulin resistance indices, body composition and maximum oxygen consumption were determined. Finally, data were analyzed by Stata software.
Results: Statistical data analysis illustrated that the amounts of irisin serum were significantly increased in exercise training group than control group (14.75±6.22; p=0.022) after the intervention. Also, only body fat percentage (1.242±0.57) and max oxygen consumption (1.509±0.328) of subjects were significantly increased (p=0.034 and p=0.0001, respectively). However, there were not statistically significant changes in irisin- related insulin-resistance indices (p>0.05).
Conclusion: Current study presented that serum irisin was increased after 30 submaximal exercise training sessions regardless of insulin resistance changes in obese men.

Abstract
Background: Individual differences, especially gender, have an important role on individuals responds to the emotions. In cognitive science investigations, the analysis of biological signals has been introduced as a confident way to evaluate such responses. In this paper, by adopting a comprehensive approach on biomedical signal processing techniques, a precise examination on women and men differences in affective responses has been provided into different emotional stimuli, including fear, sadness, happiness, and peacefulness.
Materials and Methods: Accordingly, signal processing methods were divided into three general categories, linear, wavelet, and non-linear based techniques. In the proposed method, different features from each of three categories and from three autonomic signals, including electrocardiogram (ECG), finger pulse, and galvanic skin response (GSR), were extracted. To induce emotions in participants, validated emotional pieces of music were broadcast in four affective classes.
Results: The results indicate the different patterns of responses into affective incentives in women and men. The differences were more noticeable in the features of pulse signal than those of the other signals. Among emotional classes, fear resulted in the highest rate of distinction between men and women emotional responses.
Conclusion: By the comprehensive evaluation of autonomic signals and different signal processing techniques, this study has tried to offer a new insight for better understanding of gender differences in emotional responses. In addition, it will help the researchers to adopt appropriate decisions in identifying efficient processing approach to deal with large amount of information achieved from signal analysis.

Abstract
Background: Protein tyrosine phosphatase 1B (PTP1B) is a key enzyme in dephosphorylation of the insulin receptor (IR) and it is a central factor to induce the insulin resistance. The purpose of this study was to evaluate the effect of 12-week aerobic training on protein tyrosine phosphatase 1B gene expression and insulin resistance in diabetic rats.
Materials and Methods: In this study, 16 Wistar rats were divided into aerobic training and control groups. After inducing diabetes intra protaneally, aerobic training group performed training protocol for 12 weeks and 5 session/week. The duration and speed of each session increased progressively as 18 to 26 m/min and 10 to 55 min, respectively. Then, blood and tissue (from gastrocnemius) sampling were carried out in diabetic rats. Insulin resistance markers and PTP1B gene expression were evaluated by commercial kits and Real-Time PCR method, respectively.
Results: Findings showed that PTP1B significantly was decreased in diabetic rats of aerobic training group (p=0.0001). Also, glucose and insulin resistance significantly was decreased in aerobic training groups (p=0.02 and p=0.006, respectively). However, insulin in control rats was significantly increased (p=0.015).
Conclusion: It seems that, current aerobic training protocol has capability to decrease PTP1B and insulin resistance in diabetic rats. Furthermore, the direct correlation between PTP1B and insulin illustrated that any changes in insulin resistance due to exercise training associated with diminution of negative regulation of insulin signaling pathway.

Abstract
Background: In response to the exercise, variety of inflammatory and anti-inflammatory changes in cytokines were occurred into the tissue spaces and also to the systemic circulation. The purpose of the current study was to determine the effect of three-week intensive interval training on Lipocalin-2 and Interleukin1-β in healthy and adult rat hippocampus.
Materials and Methods: Twenty Wistar rats were divided into training and control groups. Training group performed 15 (bouts) × 4 (min) exercise training for 60 min with 85 to 90% of VO2max used for four sessions/week (for 3 weeks). Then, blood (for ELISA analyzing) and tissue sampling was performed from rat’s hippocampus and they were evaluated by using a Real-Time PCR method. Also, independent and paired t tests were used to define within and between group differences.
Results: Findings showed that gene translations of Lipocalin-2 and Interleukin1-β were significantly decreased in rat’s hippocampus (p=0.0001 and p=0.0001, respectively). Also, similar decreases were shown in serum levels of Lipocalin-2 and Interleukin1-β in rats (p=0.017 and p=0.003, respectively).
Conclusion: It seems that significant decrease of Lipocalin-2 subsequent of short-time intensive interval training is due to decreasing and significant changes in Interleukin1-β. Also, current training protocol on treadmill can significantly decrease levels of Lipocalin-2 and Interleukin1-β in rat serum and hippocampus.

Abstract
Background and Aim: one of the key concepts in physical education and sport science is the process of talent identification. The purpose of this research was to investigate the effect of PPARα gene polymorphism on some of the athletic performances of non-athlete 10-12-year-old children.
Materials and Methods: The present project was carried out in the form of semi-experimental and field-based research with salivary sampling. To determine the polymorphism of the genes, the methods used included saliva sampling, salvary DNA extraction and PCR-RFLP method and exercise tests included the Shuttle run, standing broad jump and 20m sprint. Our subjects consisted of 118 non-athletic healthy boys of Marand from 10 to 12 years old. After comparison with Hardy-Weinberg equilibrium, frequency of genotype was tested with Leven, Fisher and Kolmogorov-Smirnov tests. Using one-way covariance analysis, the mean group phenotypes was compared with each other. Type of polymorphism as a predestine variable and the athletic performances of 20m shuttle run, standing broad jump and 20m sprint test were considered as the criterion variable. All analyzes were performed by SPSS 22.
Findings: The results showed that the subjects with PPARα gene GG polymorphism had better performance in the endurance tests than subjects with CC and GC polymorphism.
Conclusion: It can be concluded that GG polymorphism is related to the endurance activities, but CC and GC polymorphisms do not have a particular predominance in the endurance, speed and power activities. |

Abstract
Background and Aim: In Iran, one quarter of couples experience infertility, which can affect various aspects of their marital life. The aim of this study was to compare psychological characteristics in fertile and infertile women referring to health centers and an infertility center in Qom.
Materials and Methods: This descriptive-analytical cross-sectional study was carried out on 160 women. of all, 80 women were selected via simple random sampling method and were among those in reproductive age who referred to health centers to receive routine childcare services. The other 80 women were selected via simple random sampling method among infertile women who referred to the infertility center. The required data were collected using standard anxiety, depression, and marital adjustment questionnaires. Data were entered into SPSS V.20 software and were analyzed using Fisher’s exact test, independent t-test and Chi-square.
Findings: There were a significant difference between the two groups in terms of the mean scores of depression (p=0.005), anxiety (p=0.02), and marital adjustment (p=0.01), as the mean score of depression and anxiety was higher in fertile women than in infertile women. However, the mean score of marital adjustment was higher in infertile women than in fertile women.
Conclusion: Since fertility can be dependent on psychological factors and other underlying factors of an individual, therefore, it is necessary to consider the educational needs of fertile and infertile women. |

Abstract
Background and Aim The occupational environment, the type of work overload or underload, physical risks, how individuals adapt to the workplace, and face the family - work constitute the sources of stress or occupational distress. Job stress emerges as the duties and tasks assigned to people are more than their abilities. This study aimed to investigate the relationship between stress management training and work ethics of employees.
Methods & Materials This research was an applied study in terms of purpose, a mixed exploratory (qualitative and quantitative) study in terms of data, a content analysis (qualitative stage) and cross-sectional survey (quantitative stage) in term of conduct. The study population in the qualitative section comprised experts (Experts in Psychology, Educational Management, and Social Medicine) according to the inclusion and exclusion criteria. In the qualitative section, the study population included experts and managers who had received stress management training. Sample size and sampling method in qualitative part was based on the principle of theoretical saturation, resulting in 12 people using purposive sampling method. In the quantitative part, the sampling was based on the Cochran’s formula, resulting in 220 people who were selected using cluster sampling method.
Ethical Considerations This barcode research was presented to the Ethics Committee and registered in the system (IR.IAU.TNB.REC.1400.121).
Results The results showed that to deal with stressful situations, three basic strategies of event-focused coping, anxiety-focused coping, and avoidance-focused coping strategies can be used for stress management training models. Overall, the components presented for coping with stressful conditions have the necessary and appropriate validities. All three main coping strategies (event-focused, anxiety-focused, and refusal-focused) are suitable for explaining and fitting. So, they all are reliable and confirmed in the current research questionnaire of coping with stress.
Conclusion Strategies for coping with stressful situations have a different effect on people’s professional work ethics so that the event-focused coping strategy has a significant positive relationship with professional ethics. On the other hand, the anxiety-focused and avoidance-focused coping strategies have negative and decreasing relationship with professional ethics. The more emphasis on the event-focused coping strategy, the more would be the professional ethics of individuals and the more emphasis on the anxiety-focused and avoidance-focused coping strategies, the less would be the professional ethics of individuals..

Abstract
Background and Aim Adropin is a new hormone plays an important role in improving lipid metabolism and vascular protection. The current study aims to determine the effect of eight weeks of high-intensity interval training (HIIT) on Adropin level and nitric oxide (NO) metabolites in overweight men.
Methods & Materials This is a quasi-experimental study with a pre-test/post-test design. Participants were 32 overweight men (Mean±SD age: 30.5±3.07 years, BMI: 27.93±4.2 kg/m2). They were randomly divided into two groups of HIIT (n=16) and control (n=16). The VO2max test was first conducted. Then, the HIIT group performed 8 weeks of HIIT (3 days per week) at 20 sessions of 30 seconds with a 13-s interval between each session. Body composition was measured using a bioelectrical impedance analyzer and the blood sampling was done for measuring Adropin and NO metabolites by ELISA kits in pre-test and post-test phases. The data analysis was done by repeated-measures ANOVA. The significance level was set at P<0.05.
Ethical Considerations This study was approved by the ethics committee of the University of Tehran (Code: IR.UT.REC.1395007). All procedures were in accordance with guidelines of the declaration of Helsinki.
Results There was a significant difference in Adropin between HIIT and control groups (0.88±0.256; 95% CI: 0.26-1.5 ng/mL). There was also a significant difference in NO metabolites between the two groups (7.5±3.03; 95% CI: 0.85-14.15 ng/ml). Moreover, there was a positive relationship between Adropin and NO metabolites in overweight men (r=0.498, P=0.0001).
Conclusion It seems that HIIT can attenuate cardiovascular diseases by increasing Adropin and NO and can improve cardiovascular fitness (VO2max) and body composition of men with overweight.

Abstract
Introduction: One of the biggest environmental challenges of the 21st century is the phenomenon of climate change and global warming, which can cause numerous health problems. One significant health issue associated with climate change is the increase in the prevalence of heat stress, particularly in occupational encounters in hot outdoor environments. So this study aimed to predict and model temperature and humidity indices in the coming decades in a dry climate.
Methods: This study obtained daily atmospheric parameters, including minimum temperature, maximum temperature, and relative humidity of Kerman station, representing a dry climate, for a period of 30 years (1965 to 2005) from the meteorological organization. Modeling of these parameters and calculation of the Temperature and Humidity Index (THI) were performed using the atmospheric general circulation model HadGEM2-ES and the CORDEX dynamic microscaler model. Three different radiative forcing scenarios, including optimistic (RCP 2.6), intermediate (RCP 4.5), and pessimistic (RCP 8.5), were considered for the coming decades (three 30-year periods from 2011 to 2099). The Ethics Committe of Iran University of Medical Sciences (IUMS) approved the present study (Code: IR.IUMS.REC.1400.020).
Results: The results of the study showed an increasing trend for minimum and maximum temperature parameters in all three time periods using the three scenarios considered. Moreover, the increase in temperature in the decades of 2099-2071 was more pronounced compared to the previous decades. The results also demonstrated an increasing trend in the THI index based on all three scenarios. The average results obtained using these scenarios showed an increase of 2.11, 2.53, and 3.3 degrees Celsius, respectively, in this index until the end of the last century compared to the base decades.
Conclusions: Overall, the increase in temperature and the investigated THI index in the studied station, based on all three scenarios, will lead to changes in thermal comfort. Higher levels of thermal discomfort will not only occur in hot months and seasons but also in other seasons. Therefore, proper planning should be implemented to address the adverse effects of climate change on people's health.
