Introduction: Incidences of overweight obesity are increasing in the world and it is an alarm for health community. The present study was designed to investigate the relationship between dietary habits with body mass index in Urmia. Materials and Methods: In this study, 453 female students were selected by multi-stage sampling. Anthropometric indices including height, weight and waist circumference were measured using standard methods and calibrated instruments. The dietary habits were determined using a researcher-made questionnaire. Results: In this study, the frequency of side activity during meals was significantly higher in overweight and obese individuals than in subjects with normal weight (P = 0. 034), and physical activity significantly higher in subjects with normal weight than overweight and obese (P = 0. 001). Consumption of breakfast every day before going to school (P = 0. 04), eating three meals regularly (P = 0. 003), and healthy snack at school (P = 0. 05) were directly related to underweight. In the multiple logistic regression model only eating three regular meals (OR = 1. 837, 85% CI (1. 35-2. 51), P = 0. 005) had a direct association with underweight. Conclusion: The results of this study show that side activity during meals increased risk of overweight and obesity. Eating all three meals regularly and eating breakfast every day before going to school were associated with an increased risk of underweight.

Introduction: The photocatalytic process has been used for many years in industrialized countries as a solution to the world's environmental pollution. During the oxidative photo-catalytic processes, the pollutants are completely degraded by UV irradiation in the presence of semiconductor catalysts, and are converted to CO2 and H2O. In this work, for the first time, the use of a 9-Watt UVC lamp with synthetic zinc oxide nanoparticles for degradation of atenolol is studied. Materials and Methods: The main objective of this work is to investigate the effect of synthetic zinc oxide photo-catalyst on the rate of destruction of atenolol as an organic pollutant in wastewater using lowintensity UV light. The effects of parameters such as concentration of atenolol, amount of photo-catalyst, pH, stirring rate, atmospheric nitrogen, and presence of various ions are studied in the photocatalytic reaction. Results: An oxidation reaction is performed under the optimal experimental conditions, i. e. 20 mg L-1 of atenolol, 10 mg L-1 of the photo-catalyst, pH 7. 0, and a stirring rate of 600 rpm. After 120 minutes of irradiation, atenolol was degraded completely. Kinetic studies under optimized conditions are shown pseudo-first order kinetic. Conclusion: The results of this study indicate the acceptable performance of the photocatalytic degradation process of synthetic zinc oxide nanoparticles and 9-watt mercury vapor lamp in the decomposition of atenolol.

Introduction: The deposition of β-amyloid in the brain is a pathologic feature of Alzheimer's disease (AD). Low doses of morphine, can enhance memory. The aim of present study, was to investigate the therapeutic efficacy of morphine on memory in Healthy and Streptozotocin (STZ) Rat Model of AD. Materials and Methods: In first experiment animals were divided to: Control and Morphine group which were injected with saline and Morphine (5mg/kg, ip) for 10 days. In the second experiment animals were divided to: control, sham operated and groups treated with STZ and STZ plus saline or morphine (2 mg/kg. ). For induction of AD, STZ (3 mg/kg, 10 μ l/injection site) were administered into lateral ventricles. Morphine or saline, were injected for 10days. All rates were trained in the Morris water maze. Results: Our results show that chronic injection of Morphine (5mg/kg) impaired spatial learning but improves spatial memory in Healthy rats. our results also show that i. c. v. injection of STZ significantly increased escape latency and Swimming distance to find the hidden platform in comparison with the control group (P<0. 05). The amnesic effect of STZ was prevented in rats treated with Low doses of Morphine, So The latency time and Swimming distance to find the platform in the STZ+ Morphine (2 mg/kg) group rats were significantly lower than STZ group (P<0. 05). conversely, the percentage of time spent and distance swimming in the target quadrant in the probe test in the STZ+ Morphine group rats were significantly higher than those in the STZ group. Conclusion: Higher doses of Morphine, impairs, learning in Healthy rats, whereas Low doses of Morphine, improved, learning and memory in the STZ rat model of AD. The results suggest that treatment with Low doses of Morphine is useful for treatment of cognitive impairment in AD.

Introduction: With attention to considered various cognitive beliefs in psychopathology of disorders, the purpose of this study was comparison of cognitive beliefs include; thought action fusion (TAF), responsibility and the overestimation of threat (RT), and overimportance and control thoughts (ICT), perfectionism and the intolerance of uncertainty (PC) in obsessive-compulsive disorder (OCD), generalized anxiety disorder (GAD), major depression disorder (MDD) and normal group for more clarification psychopathology of these disorders. Materials and Methods: This study is causal-comparative research. The clinical samples include patients with OCD, GAD and MDD that referred to Sari Shahid Zareh hospital in 2015. From each of these clinical groups and normal people, 30 persons were selected available sampling method and accomplish obsessive beliefs questionnaire and thought action fusion scale. Data were analyzed by MANOVA. Results: The result of MANOVA and Tukey posthoc test showed that OCD group were significantly higher than other groups in TAF, RT and ICT (p<0/001), but in PC didn't show the significant difference between OCD and GAD groups (p<0/086). Also, the result was shown that in all of these cognitive beliefs OCD and GAD groups were significantly higher than depression and normal groups (p<0/001). Conclusion: According to this result it seems that TAF, RT, and ICT are more specific for OCD but about PC there isn't this specialty and it is a common cognitive vulnerability in OCD and GAD. Thus considering this result can be effective in designing more specific psychotherapeutic interventions.

Therefore, this extract can be a good option for future studies in In Vivo to provide antibacterial drugs.

Introduction: Menopause is natural phenomenon and it is a stage of a woman's life in which, the menstruation period ends as a result of the reduction of the ovaries activity and the lack of estrogen. Since blood pressure and insulin resistance is a major problem in older women, The purpose of this study would be studying the effect of combined training with and without consuming the flaxseed on the Insulin resistance and blood pressure of postmenopausal women. Materials and Methods: This quasi-experimental study, 27postmenopausal women with the age group of 50 to 60 years old and the BMI equal to 25 to30kg/m2, were selected using the available sampling method. Then they were randomly divided into two groups called the combined training(12people)and the combined training plus flaxseed(15people). The aerobic exercise was performed with the intensity of 60to80 percent of the maximal heart rate and the resistance exercise with the intensity of60to80 percent of a maximal repetition. complementary was given by using25 gr of the milled flaxseed. The blood samples were collected for measuring insulin resistance and analyzed using SPSS software and Independent and independent t test, respectively, to compare intra-group and inter-group differences at a significant level of P <0. 05. Results: The results indicated that eight weeks of combined training with flaxseed consumption caused an increase maximal oxygen consumption(p=0. 001), decrease in BMI(p=0. 001)and reduce blood pressure(p=0. 001), Combined exercise alone significantly decreased BMI(p=0. 001)and decreased blood pressure(p= 0. 001). Conclusion: It seems that eight weeks of combined training alone and with flaxseed consumption can improve aerobic fitness, body composition and blood pressure in postmenopausal women.

Introduction: The amount of exclusive breastfeeding in Iran during the years 1991-2015 is estimated to be between 10%-53%, which should be promoted for the baby according to the importance of breastfeeding. In order to intervene in breastfeeding promotion in the first step, the effective factors should be determined. Due to the lack of standard and indigenous questionnaires on the determinants of effective factors on lactation, this study aimed to design and validate native instruments for measuring the factors affecting exclusive breastfeeding in nulliparous women of Kashmar city based on the theory of planned behavior. Materials and Methods: In this cross-sectional study, original tool was designed using the literature review and need assessment of beliefs based on the theory of planned behavior and the researcher's experience in lactation. To validate the tool, face validity (quantitative and qualitative) with the participation of 10 nursing mothers, content-related validity (by measuring the ratio of content validity and Content Validity Index) through the panel of experts with the participation of 10 experts in health education and tool design and validity Structures (through confirmatory factor analysis) were studied by selecting 156 of the survey population. The reliability of the tool was examined by internal consistency (Cronbach's alpha) and Ray-Test Test (ICC). Results: The initial questionnaire was designed with 67 items. In the face value and validity of the qualitative literature content, some questions were changed and in the face validity, 6 items were omitted due to the score of less than 1. 5. In content validity, considering the cutting point 79% to measure content validity index and cut point of. /62 for the ratio of credit, 18 items were deleted. Structural validity was performed by confirmatory factor analysis in LISREL software, which showed RMSEA = 0. 072, AGFI =. /96. 4. The Reliability of the tool was also approved using methods such as internal consistency (α = 0. 832) and its stability through retest method (ICC = 70. 38). Conclusion: The results show that a questionnaire designed to measure the effective factors on exclusive breastfeeding in primipara women based on the theory of planned behavior is a reliable and trustworthy tool with acceptable reliability and validity and we recommend it in related studies.

Also, using random sampling method, 40 students (25 girls and 15 boys) from Tehran area 2 were selected as control group. After collecting the rumination questionnaire, subjects were assessed by assignment test of curci blocks (spatial memory test). The multiple covariance analysis was used to analyze data. Results: The results revealed that there is no significant difference in spatial memory between the two groups (P = 0. 001); and the result showed that rumination could not moderate the relationship between diabetes type 1 and spatial memory. Conclusion: Diabetes mellitus disease did not affect spatial memory. Also, high rumination did not interfere with spatial memory function.

Introduction: This study aimed to determine the effectiveness of eight weeks of endurance training with ginger supplementation on CRP and TNF-α in young girls aged 20 to 30. Materials and Methods: In this semi-experimental study, 32 young girls 20-30 years old were randomly assigned in four groups (control, supplement, practice and practice + supplement). The weight mean and standard deviation of participants were (61. 17 ± 11. 1) kilograms, and their body mass index were (23. 45 ± 2. 7). Training program was planned for eight weeks and three sessions per week. Each session consisted of 45-60 minutes with an intensity of 65-75 Vo2 max. The supplement and practice + supplement groups received daily one gram of ginger (Four 250 mg capsules) for 8 weeks. Blood samples were taken 48 hours after the last training session. The data were analyzed using Kolmogorov-Smirnov, Levene's Test, Covariance (ANCOVA) And Bonferroni and by SPSS 20. Results: The findings showed that endurance training decreases significantly TNF-α in Young girls 20-30 years old (P <0. 001), It was also effective in reducing CRP values (P = 0. 002). Intake of ginger supplementation decreases significantly TNF-α (P <0. 001), but there was no significant effect on CRP values (P =0. 281). Eendurance training along with intake of ginger supplementation decrease significantly the values of CRP and TNF-α (P <0. 001). Conclusion: It seems that endurance training and supplementation of ginger with the necessary precautions can be used as an effective agent for preventing and delaying cardiovascular diseases.

Introduction: Intensive, long-term activity can damage the immunity system and cause inflammation. So, a natural anti-inflammatory intermediate like green tea has attracted the interests. The objective of the present study was to examine the impact of green tea consumption and intensive aerobic exercise training on body composition, creatine phosphokinase and lactate dehydrogenaseparameters in sedentary young men. Materials and Methods: Thirty-eight sedentary young men (age: 19. 87± 1. 63 years) were participated in study and were randomly divided into four groups: green tea + aerobic training, aerobic training, green tea, and control. The subjects took three mg green tea or placebo a day with their meals. Also, green tea + aerobic training and aerobic training groups had aerobic training with 55-85% of maximum heart beat rate three sessions a week for one month. Blood samples were taken before and after four weeks and 24 hours after El-Estado test and their creatine phosphokinase and lactate dehydrogenase were measured. Data were analyzed with t-paired test and covariance test. Results: It was revealed that fat percentage was significantly lower in green tea group (p < 0. 001) but, no significance was observed in other variables. Conclusion: It seems that green tea consumption with regular, short aerobic activities can favorably affect subcutaneous fat percentage.

Introduction: Leptin is mainly produced in adipose tissue and plays an important role in regulating glucose metabolism. It seems that exercise training can improve glucose homeostasis and leptin level in human. Therefore, the purpose of this study was to determine the effect of aerobic interval, non-liner resistance and concurrent training on the level of serum leptin and insulin resistance in overweight women. Materials and Methods: In this semi-experimental study, 40 volunteers women were randomly assigned (n = 10 each) to non-training control, aerobic interval training, non-liner resistance training, or concurrent training group. Subjects in Exercise group were on 12-week supervised exercise training program of four three per week, whereas the control group maintained a sedentary lifestyle. Insulin resistance and leptin were assessed from fasting blood samples before and after 12-week of intervention. All data were analyzed using Statistical software version 24 and the levels of statistical significance were set at P<0. 05. Results: At baseline, fasting blood sugar, insulin, HOMA-IR and leptin were not different between the groups. Fasting blood sugar improved in concurrent resistance group (P=0. 005), whereas no relevant change occurred in other groups. In other hand, insulin, HOMA-IR and leptin did not change throughout the study. Conclusion: In summary, compared to either aerobic interval or nonliner resistance training alone, concurrent training is as efficacious for improving fasting blood sugar in overweight women.

Introduction: So far, no study has ever surveyed the effectiveness of injectable and oral forms of the Glucosamine compared with chondroitin sulfate and hyaluronic acid on physical function and pain in osteoarthritic patients. The aim of this study is to evaluate the clinical efficacy of glucosamine compared with chondroitin sulfate and hyaluronic acid in relieving pain and function of people with osteoarthritis.

Results: Showed that there is a significant difference between the mean quality of family relationships and the mentality of the experimental and control group (P <0. 001). Also, there was a significant difference between the frequency of self-harm in two groups (0. 05) > P). Conclusion: A positive change in mentalization and improvement in family relationships can reduce self-harm. The results of the research are based on the Mentalization Based Therapy of the quality of family relationships and self-harm behavior in adolescent girls.

Introduction: Postpartum depression (PPD) is an episode of major depression that has many negative effects on the mother and the newborn child. Some factors have been identified as the predictive factors for PPD in peripartum such as Peripartum and Postpartum Depression, and preterm labor. The aim of this study was to investigate the relationship between breastfeeding and PPD. Materials and Methods: This research was a longitudinal study conducted in Darreh Shahr County, Ilam Province in 2015-2016. Of the 365 women who were pregnant about 38 weeks, 303 ones who had no depression according to the Edinburgh questionnaire were put under the study. The under study group was reexamined again with the Edinburgh questionnaire 6 to 8 weeks after delivery. 31 of them achieved grade 13 or greater of whom 29 ones were approved that had depression by a psychiatrist. The study was conducted on this group. Afterwards the relationship between breastfeeding and PPD and other effective variables including type of delivery, place of residence and etc, was investigated by dividing the samples into two groups namely depressed and non-depressed subjects. Results: Among the variables studied it was only breastfeeding that was connected to postpartum depression (P=0/004). This relationship was also positive (P =0/ 02) in the multivariate regression analysis. Conclusion: The results revealed that in the case of exclusive breastfeeding, the rate of PPD was decreased. Due to the high rate of prevalence of PPD in some parts of the country, it is important to reduce the rate of this prevalence, the special health care is important during the postpartum period, relative to the initial, and the continuation of exclusive breastfeeding.

Elimination of these causes can have a great impact on reducing risks, reducing costs and improving the quality of the operating room.

Introduction: Thiopental Sodium is a commonly used drug in anesthesia, but it is not ideal because barbiturate is prohibited in acute and allergic porphyria, and is not recommended in asthmatic and hypovolemic patients. Propofol is the newest drug in anesthesia due to its rapid onset, short duration of action, anti-nausea and a feeling comfort after use, its consumption is increasing. It is also safe in porphyry and asthma. This study compares the use of sodium antiproliferative drug propofol to reduce the need for opiate. Materials and Methods: This study was conducted on 173 patients admitted to Sabzevar Hospital. Patients were randomly divided into two study and control groups. Anesthesia induction was performed in the study group with propofol 2. 2 kg / mg and with thiopental sodium 5 kg / mg, in both groups, blood pressure and heart beats were measured before and after induction and minutes 1, 5 and 11 after intubation. Within 1-2-3-4 hours after operation with a pain control chart, the intensity of the pain was checked and the data were recorded. Results: In the propofol group at the 4th hour, 44 individuals feel mild pain, and 9 had moderate, but severe pain was not reported (P=0/44). In the thiopental group at the fourth hour, 53 patients feel mild pain, 11 had moderate and 5 had severe pain (P=0/44). Conclusion: Propofol increases the threshold of postoperative pain, so it can be a good alternative to thiopental.

Introduction: Self-efficacy is a predictor of health behaviors, including physical activity and eating habits. Health literacy is the capacity of individuals to obtain, process and understand information and basic health services needed for health decision making. The purpose of this study was to determine the effect of education based on self-efficacy theory on health literacy, self-efficacy of regular eating habits and self-efficacy of regular physical activity in second-grade female students Materials and Methods: This research was a Semi-experimental study in which 92 female students aged 15-18 years were randomly selected through simple random sampling and assigned to two groups of test and control. Data gathering tools were demographic information, Health Literacy (NVS), selfefficacy of regular eating habits and self-efficacy of regular physical activity questionnaires. Educational intervention was designed and implemented in a 40-minute training session in the experimental group. Data analysis was done using descriptive and analytical tests by SPSS software Results: Before intervention, there was no significant difference between the two test and control groups in terms of mean score of health literacy, self-efficacy of regular eating habits and self-efficacy of regular physical activity. But after intervention, there was a significant difference in health literacy score (P= 0. 001), self-efficacy of regular eating habits (P<0. 001) and self-efficacy of physical activity (P<0. 001) in the experimental group. Conclusion: The results showed that the design and implementation of educational interventions based on self-efficacy theory can lead to increased health literacy, self-efficacy of regular eating habits and self-efficacy of regular physical activity of students.
