An important factor of mental health is praying. The purpose of this study was to develop a questionnaire for assessing students' attitude towards prayer. Methods: This cross-sectional study was conducted on 500 students in the Jan. 2017 at the University of Welfare and Rehabilitation Sciences (USWRS). The first draft of the prayer questionnaire (68 items) was based on literature review. To ensure content validity and face validity, the research panel team examined the questionnaire and the items were reduced to 33. Thereafter the questionnaire was tested by 9 students and also an expert panel team (10 persons) examined face and content validity. Then construct validity, internal consistency, and test- retest reliability of were assessed. Finally, Receiver Operating Characteristic (ROC) curve was used to assess the predictive ability of the attitude questionnaire and to inform the choice of a cut-off point. Data analysis was carried out using SPSS 21 software. Results: 18 items were omitted based on the content validity ratio (CVR<0.6) and 11 items were  added by the expert panel. For this questionnaire, the average content validity index of relevance, simplicity, and clarity were 0.879, 0.976 and 0.958, respectively. Scale- Level content validity index was calculated 0.937. Cronbach's alpha coefficient (0.95) confirms the high internal consistency and test-retest coefficient (0.903) confirms stability of this questionnaire. Factor analysis identified four factors, based on 22 items, which explained a total of 68% of the total variance. The cut-off point score by using the ROC curve analysis was calculated 53.5. Conclusion: Our finding showed that the students’ attitude questionnaire with 22 items provided a reliable and valid tool to detect attitude of students towards praying. This questionnaire can be used in other universities in Iran.    }, Keywords = {Validity, Reliability, Factor analysis, Mental health, Attitude, Praying}, volume = {25}, Number = {1}, pages = {1-10}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-5054-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-5054-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2018} } @article{ author = {dehdari, tahereh and dehdari, Laleh}, title = {Investigate the knowledge and performance of employers regarding suitable cooking methods for reducing aromatic hydrocarbons in meat}, abstract ={Background: Given the importance of aromatic hydrocarbons in developing cancer, the necessity of educating individuals about methods to reduce it in food products and the importance of assessing individuals’ knowledge and practice to design effective educational programs, the present study aimed to determine the knowledge and performance of employers regarding suitable cooking methods to reduce the production of aromatic hydrocarbons in meat in 2017. Methods: In a cross-sectional study, 128 employers who were employed in Iran University of Medical Sciences, Tehran, Iran were selected randomly. Data were collected by a 46-item questionnaire and then analyzed through Pearson's correlation coefficient, One-Way ANOVA and T- test. P>0.05 was considered significant. Results: Finding showed that about half of the participants were informed about meat barbeque on charcoal, frying method and smoking methods that generate aromatic hydrocarbons in meat. In addition, about 50% of participants expressed that steam and boiled methods for cooking meat can reduce the generation of aromatic hydrocarbons in meat. Most consumed meat among participants were meat fried, boiled and then barbequed on charcoal, respectively. Only 36.7% of participants didn’t eat the burned parts of meat. Conclusion: Given the lack of individuals’ information about the role of meat cooking methods in the production of aromatic hydrocarbons and the methods for reducing its production, it is imperative that health workers provide essential information in the cancer prevention education sessions.  }, Keywords = {Aromatic hydrocarbons, Performance, Knowledge, Employer, Meat cooking}, volume = {25}, Number = {1}, pages = {11-19}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-4966-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-4966-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2018} } @article{ author = {Rajabi, Ali and Siahkouhian, Marefat and Akbarnejad, Ali}, title = {Comparison of the effect of a therapeutic exercise program and oral administration of saffron on the levels of IL-6, TNF-a and glycemic control in type 2 diabetic women}, abstract ={Background: The purpose of this study was comparison of the effect of a therapeutic exercise program and oral administration of saffron on the levels of IL-6, TNF-a and glycemic control in type 2 diabetic women Methods: 48 type 2 diabetic obese women were randomly divided into four equal groups (saffron + training, training + placebo, saffron, placebo). The saffron group + training and training + placebo groups performed aerobic training with intensity of 60-75% of maximal heart rate for 8 weeks (three sessions per week). Daily dose of 400 mg of Saffron sprout powder (once a day) was used for two months. The placebo contained 400 mg of wheat flour. The following IL-6, TNF-a, Blood glucose and HbA1c variables; lipid profiles and HOMA-IR were tested. The Shapiro-Wilk test, variance analysis with repeated measures, Bonferron's post hoc test, and one way analysis of variance with LSD post-test. Results: In the post-test phase, the pre-test the variables IL-6 and TNF-α, blood glucose and HbA1c in intervention groups decreased significantly, and also in the post-test between group, saffron + training with training + placebo, saffron + training  with saffron, saffron + training  with placebo and saffron with placebo there was a significant difference (p<0.05). Also, in variables of weight and BMI, there were statistically significant differences between saffron + training with placebo groups, training + placebo with placebo groups, and saffron with the placebo groups (p<0.05). Conclusion: It can be possible aerobic exercise and saffron consumption have a protective effect against the increased levels of blood glucose and HbA1c. It is possible that the reduction of blood glucose, IL-6 and TNF-a in saffron recipients is due to the presence of saffron metabolites, especially flavonoids (crostein and crocin) and increased antioxidant defense system through saffron.}, Keywords = {Type 2 diabetes, Aerobic exercise, Saffron, IL-6, TNF-a.}, volume = {25}, Number = {1}, pages = {20-33}, publisher = {Iran University of Medical Sciences}, url = {http://rjms.iums.ac.ir/article-1-4930-en.html}, eprint = {http://rjms.iums.ac.ir/article-1-4930-en.pdf}, journal = {Razi Journal of Medical Sciences}, issn = {2228-7043}, eissn = {2228-7051}, year = {2018} } @article{ author = {Haeri, Azadeh and Rabbani, Shahram and Mahboubi, Arash}, title = {Nanoparticle applications in cardiovascular diseases}, abstract ={Cardiovascular diseases remain the leading cause of death worldwide.

Therefore, continuous monitoring of blood pressure in health centers is a priority for deciding the type of therapeutic treatment in these patients. The aim of this study was to provide a decision-making model based on neural network and quality control charts for monitoring and continuous monitoring of blood pressure. Methods: This was an applied-developmental study carried out in cross-sectional method during 2014 to 2015, on 175 patients with hypertension in Ali ibn Abi Talib Hospital of Zahedan. The actual behavior of the systolic and diastolic blood pressure of these patients under the online model and its expected behavior was studied under the Offline model and in the form of an artificial neural network. By evaluating the true behavior of patients with their modeled blood pressure, residual values are produced and introduced as inputs of EWMA quality control charts in two steps to determine the state of the patient out of control and determine the status of the patient.

The compounds in the Artemisia deserti (A. deserti) have antimicrobial properties. The purpose of this research is investigation of the antifungal effect of aqueous and alcoholic extracts of plant A. deserti on the M. furfur in the laboratory conditions. Methods: From the A. deserti plant by the method of percolation, the aqueous and alcoholic extracts were prepared and then concentration of 40, 50, 60 and 70 mg/ml was made. In order to evaluate the antifungal effects of these extracts on M. furfur in laboratory Disc diffusion method, Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentrations (MFC) was investigated.
