Introduction: Troponin- T is the best biological marker of heart injuries, that isn't affected by sex, age, birth weight and gestational age. Myocardial damage in infancy is a risk factor eventual cardiac disease. This study carried out for cardiac evaluation of neonates with mechanical ventilation by Troponin T.Methods: This case-control study carried out on 60 infants that were admitted in neonate intensive care unit of Amir Almomenin hospital, Zabol, Iran. Neonates were enrolled in 2 groups: those who were supported with ventilator as cases and those who were not supported with ventilator as control group. We assayed the serum samples from neonates for Troponin T for myocardial injury. Data was analyzed using Pearson correlation, Mann-Whitney and Chi-square tests by SPSS software and significance level of 0.05.Results: Troponin T levels in case group was significantly different than it in control group at the beginning of the study and 24 hours after that (P<0.05). Generally, Troponin T level in case group was significantly higher than it in control group.Conclusion: We conclude that evaluation of newborn with mechanical ventilation enhances the possibility of occult and clinically myocardial injury. The results, in this study, suggest that Troponin T is a useful and early marker for myocardial injury.

Introduction: Diabetes mellitus is often associated with chronic neuropathy, a condition which is due to the disturbance in the function of peripheral nervous system. Studying the effects of antioxidants in relieving neuropathy is of a great clinical importance. The aim of this study was to compare the effect of aqua extract of date and Melatonin in preventing neuropathic hyperalgesia in Streptozotocin-induced diabetic rats.Methods: In this experimental study, 40 male Sprague dawley rats weighing 200-250gr were divided into five groups of control, sham, diabetics+melatonin and diabetics+date extract and diabetic+solvent. Diabetes was induced by intraperitoneal injection of streptozotocin (45mg/kgB.W) solved in 0.05M citrate buffer. After confirming diabetes statue, experimental groups received either melatonin (10mg/kg/day), date extract (4mg/kg/day) or solvent for a duration of 6 weeks. At the end of the 6th week, all groups were investigated using Hot plate and Tail flick tests. Analysis of variance with significance level of P<0.05 was used for statistical analysis.Results: In Hot plate test, solvent group showed significant decrease in the time of thermal pain response compared to the non diabetic control group (P<0.01). Date extract group showed an increase in the time of response to thermal pain as compared to the solvent group (P<0.01) in a way that response time was close to that in the non diabetic control group. Although time of response to pain in melatonin-administered group was close to that in the non diabetic control group, melatonin group had no significant difference with other groups. There was no significant difference among groups based on the results of Tail flick test.Conclusion: The results of this study show that both date aqua extract and Melatonin as antioxidants prevent and decrease neuropathic hyperalgesia in diabetic rats. In addition, the protective effect of date aqua extract in prevention of diabetic hyperalgesia is more than Melatonin.

Introduction: Using zinc oxide nanoparticles, as a catalyst removal of fecal pollution indicator bacteria in water, has been studied as a model of bacterial contamination. This study aims to determine the toxicity and selection of appropriate indicators to evaluate the toxicity of zinc oxide nanoparticles on the isolated bacteria Vibrio species of Bushehr coastal waters.Methods: In this experimental study, 100 samples of sea water off the coast of Persian Gulf in Bushehr coastal areas were selected.10 centigrade of each sample was cultured on the TCBS medium. In the next step, differential tests were conducted on colonies of positive oxidase. The specific concentrations of nanoparticle were prepared and paper discs were impregnated with the concentrations and then bacterial isolates from the 0.5 Mc-Farland suspensions was prepared. After incubation, inhibition zone was reported in millimeters at each concentration. Data analysis was performed using by SPSS 16 Software.Results: The strains of bacteria detected by culturing samples of raw water including Vibrio cholerae, Vibrio parahaemolyticus, Vibrio vulnificus and Vibrio mimicus. Minimum and maximum number of Vibrio strains were, Vibrio cholerae and Vibrio parahaemolyticus, respectively. Elimination of Vibrio Cholerae, Vibrio Parahaemolyticus, Vibrio Vulnificus and Vibrio Mimicus strais in concentration of 6000 mg/L zinc oxide nanoparticles were 95%, 90%, 75% and 70%, respectively.Conclusion: Due to significant effect of nanoparticle in removal of genus Vibrios, economic justification and other factors should be considered in application of nanoparticles, in eliminating bacterial pathogens in water industry.

Introduction: Lead is the major toxicant found in industrial effluent that can adversely affect environment and human health. Conventional methods for the removal of this metal from waste waters are often cost prohibitive. This study was conducted to investigate the effect ostrich feathers modified by hydrogen peroxide on lead removal from waste water.Methods: In this descriptive and practical study, ostrich feathers were used for removal of lead from model solutions. Ostrich feathers were modified with hydrogen peroxide (30% w/v) and distilled water for 18 hr. In this study, effect of pH (2-9), temperature (20-40oC), contact time (0.5-12 hr), sorbent dosage (0.3-1 gr) and initial concentration (1-15 mg/l) were investigation in batch system. All the experiments were conducted in triplicate. Experimental results were fitted to Langmuir and Freundlich isotherm models and Excel software was used for data analysis.Results: The results show that the maximum lead adsorption by modified feathers reached within pH 5, contact time 8 hr, feather dosage 0.7 g and temperature 30oC for concentration range of 1-15 mg/L. Adsorption equilibrium data fit most satisfactorily with the Freundlich and Langmuir isotherms.Conclusion: According to the results, because of its inexpensive and availability, ostrich feathers can be used as a suitable method to reduce the level of Lead from the aqueous solutions in the contaminated places throughout the country.

Introduction: Most commercial surfactants used for cleaning (as detergents) are part of xezenbiotic compounds. These compounds and products due to its toxic effects on aquatic organisms may interfere with hormonal system and consequently change the echo system. Since the biodegradation of those compounds are weak, ordinary methods are unable to break down conventional purification. Therefore, the study on the efficiency of Fenton oxidation process and optimization of the effective factors on industrial wastewater treatment detergents was investigated.Methods: This is an experimental study which was carried out on samples of detergent industri waste water. Ph level, duration, concentration of hydrogen peroxide, concentration of Iron sulfate of the samples were investigated. Using one-factor experiment plans, each factor separately with three time repeat and 95% confidence interval. The experiments were conducted based on Standard method book on water and wastewater, the data analysis was done using SPSS 11 and EXEL Software.Results: Results showed that efficacy of contamination removal was 70% and BOD to COD ratio increased from 0.2 to 0.6. Statistical analysis showed that PH, contact time, Iron sulfate concentration, and hydrogen peroxide are all effective factors (P<0.001) and their optimum levels are 3, 90 minutes, 90 mg/L, and 70 mg/L, respectively.Conclusion: The process of advanced Fenton treatment based on production of very active radicals of hydroxyl, as a new emerging technology, can be efficient for industrial wastewater pre-treatment which contains substances resistant to biodegradation.

Introduction: Studies with adults have shown that an external focus of attention results in more learning and greater automaticity than an internal focus. Hence, this study was conducted to evaluate the effects of attentional focus instructions on learning of balance skill amongst patients with Parkinson disease.Methods: In this quasi-experimental study, all Parkinson's disease patients referred to neurology clinic were examined by a neurologist and 23 patients who met the inclusion criteria of this study were evaluated using Berg balance scale. They were randomly assigned to control, external, and internal groups. The participants of each group practiced Berg balance scale for five days and then conducted the retention test, 72 hours after the last session. To compare the results of 4 stages of practice, analysis of variance for repeated data was used and P<0.05 was considered statistical significant.Results: Using Berg balance scale revealed that the participants' balance improved in all control, internal and external groups regarding performance and retention. The comparison between the groups also showed that although the external group performed better than the other two groups, there was no significant difference between them regarding performance and retention.Conclusion: The results of this study confirmed the effect of practice on improvement of balance skill amongst patients with Parkinson's disease. However, external and internal attentional focus instructions had no advantage over one another. Therefore, it seems that attentional focus instructions do not probably act similarly in all types of skills and educational environments.

Introduction: Behavioral science is an inseparable part of a comprehensive accident prevention strategy in a work place. This study reports a behavior approach used to evaluate the effects of an occupational safety training intervention on industrial textile workers.Methods: This study is a quasi-experimental based on Solomon 4-group design participatory study, which is conducted as pretest-post-test intervention. A sample of 85 workers of a textile factory participated in this study. A questionnaires and a behavior observation checklist were developed exclusively for this study. The required substantial data for intervention planning were resulted based on findings due to conducting four first phases of precede-proceed model. A combination concept of Precede-Proceed model and theory of Reasoned Action were utilized in planning and implementing the interventions. Our package consisted of training, assigned goal setting, daily verbal praise, and graphic feedback that were provided four times a week. Analysis of data was performed using Minitab software. Descriptive statistics and t-test and analysis of variance were used for comparisons between groups.Results: The mean scores on knowledge and safety practices showed significant improvement among all four groups in one month and three months post intervention, with groups 1 and 2 show the highest improvement. Our findings approved the applicability of combined models on safety practices and knowledge on the safety issues in workplace.Conclusion: Our study acknowledges the idea of applying an occupational safety training intervention package for textile industry workers and implementing health education intervention to promote safety practices in other industries.

Introduction: Spiritual issues and their relationship with other psychological components are of interesting subjects for behavioural sciences experts. The aim of this research was investigating the relationship between spiritual intelligence, personality traits and quality of life in medical students.Methods: In this analytic study, a sample of 160 medical students in 2010-11 academic years was selected randomly by using cluster sampling method. The data collection instruments were spiritual intelligence and quality of life questionnaires. For statistical analysis, SPSS 16 Software was used.Results: The results revealed that there is a significant correlations between personality traits, spiritual intelligence and quality of life (P<0.001). Spiritual intelligence had the most positive relation with quality of life, whereas neuroticism had the most negative relation with it. It was also revealed that neuroticism, conscientiousness and agreeableness had the highest role in predicting quality of life.Conclusion: The results of this research showed that there were positive and multiple relationships between spirituality intelligence, personality traits and quality of life. Spiritual intelligence had the most positive relation with quality of life, whereas neuroticism has the most negative relation with it.

Introduction: Physical and mental health of students as future human resources of each country, is of particular importance. The purpose of this survey was to determine the general health status of nursing students in Hormozgan University of Medical Sciences in 2011.Methods: In this cross sectional study, 95 nursing students of Hormozgan University of Medical Sciences were selected with convenience sampling method and their health status was assessed with Goldberg's general health questionnaire. This questionnaire consisted 28 multiple choice questions in four dimensions of physical functioning disorder, anxiety and sleep disorders, social functioning disorder and depression symptoms. Data were analyzed by descriptive statistics, t-tests and Pearson correlation coefficient.Results: Findings showed that 30.5% of the samples were male and 75.8% were residing in the dormitory. The average age of the samples was 21.12±1.44 years and their mean of total educational achievement mark was 16.12±1.02 out of 20. The findings revealed that 36.8% of the samples had general health score higher than cut off point. This indicated that the subjects from different dimensions had general health disorders, such as: physical functioning disorder 32.6%, anxiety and sleep disorders 37.9%, social functioning disorder 54.7%, and depression symptoms 17.9%. Statistical relationship showed that there was a significant relationship between general health score and age.Conclusion: Results showed that general health scores and their health related issues were both higher among the younger students. The assessment of physical and mental health status in the beginning of their entrance to the university and, even in high school period, as well as holding counseling classes could be effective in order to promote the youth health condition.

Introduction: Exam anxiety as a common phenomenon is one of the problems of educational systems that affect academic performance. This study was performed to determine exam anxiety and its relationship with demographic factors among new students in Hormozgan University of Medical Sciences.Methods: In this descriptive- analytical study, 310 new students of Hormozgan University of Medical Sciences were selected by random sampling in 2013 academic year.
