1 1735-9503 Islamic Republic of Iran/ Air Force Health Administration 431 The effect of adolescent treadmill mandatory exercise on symptoms of depression and brain inflammatory responses following maternal separation stress in mature male rats Zolfaghari F Peeri M Hosseini Mir-Jamal 1 12 2017 19 4 4 12 08 08 2016 07 01 2018 Background: Early life stressful events have detrimental effects on brain and behavior associated with development of depression. Also immune-inflammatory responses have been reported to contribute in pathophysiology of depression and many studies have indicated the beneficial effects of physical activity against stress. This study aimed to determine the effect of adolescent treadmill mandatory exercise on symptoms of depression and brain inflammatory responses following maternal separation stress in mature male rats. Materials and methods: In this work, we applied maternal separation (MS), as a valid animal model of early life adversity, to rats from postnatal day (PND) 2 to 14 for 180 min per day. At PND 28, male Wistar albino rats were randomly divided into 4 experimental groups: control, MS, treadmill mandatory exercise (TM), and fluoxetine. At PND 60, depressive-like behaviors were assessed using behavioral tests including forced swimming test (FST), splash test , sucrose preference test (SPT), and open field test. Also, real-time PCR was used for assessment of IL-6, IL-1β‎ genes expression in hippocampal samples. Results: Our result revealed that depressive-like behaviors following MS stress significantly caused depressive-like behaviors which were treated only in fluoxetine group (p<0.05). Also, increases in IL-6, IL-1β‎ genes expression were found in MS group and were decreased after treatment in both TM and fluoxetine groups (p<0.05). Conclusion: Although, mandatory physical exercise during adolescence is not able to change depressive-like behaviors, it‎ can make changes in cellular and molecular level.

University of Mazandaran, Babolsar, Iran 1 12 2017 19 4 13 21 06 06 2017 17 02 2018 Background: The physical fitness of military personnel is one of the main concerns of the military forces; because it is one of the determining factors in their efficiency and performance. The aim of this study was the monitoring of Army cadet's body composition, physical and motion fitness and providing national norms. Materials and methods: For this study, 3,000 students of University of Imam Ali consisting of first to third year entry (every entry 1000 cadets) aged between 18 and 22 were selected according to stratified random sampling method. At first, the height, weight, and body composition of the students were measured. Then physical- (sit-ups, push-ups, pull-up, and 2-mile run) and motion- (30-Ft agility shuttle run, 60-m sprint) fitness tests were performed. To compare body composition, physical and motion fitness of cadets, One-way analysis of variance (ANOVA), Scheffe and Tamhnae post-hoc tests were used. Also, Spearman correlation coefficient was used to show the relationship between body composition and the physical and motion fitness. Results: The results showed that there was a significant difference between the first, second, and third entry students about values of body composition, physical and motion fitness (p<0.05). Also, there was no strong relationship between body composition with physical fitness and motion fitness among the three groups of study subjects. Conclusion: According to the results, cadets received suitable scores in terms of body composition, physical fitness and motion fitness parameters that represent the university achievements in this field. 532 Assessment of postural control in various knee alignments Yahyaei M h Norasteh A.A i Shamsi A j h Department of Sport Injury and Corrective Exercise, Faculty of Physical Education Sport Sciences, University of Guilan, Rasht, Iran i Department of Sport Injury and Corrective Exercise, Faculty of Physical Education Sport Sciences, University of Guilan, Rasht, Iran j Department of Sport Injury and Corrective Exercise, Faculty of Physical Education Sport Sciences, University of Guilan, Rasht, Iran 1 12 2017 19 4 22 29 01 05 2017 17 02 2018 Background: Nowadays, many people participate in sport activities which may lead to the sport-related injuries. Postural control has an important role in injury prevention and athletic performance. The Aim of current study was to assess the balance stability among subjects with different knee alignments under jump and land on their dominant foot. Materials and methods: Totally, 33 healthy athletically-active females were assigned into three groups based on their knee alignment [normal knee (n=16), genu varus (n=10), genu valgus (n=7)]. To evaluate the alignment of the knee joints, the frontal plane knee angle was measured with a universal goniometer. The dynamic postural stability index was evaluated with two dynamic tasks (anterior-posterior and medial-lateral jumps) on the force plate. An independent sample t-test was to examine the differences of mean values of dynamic postural stability index between genu varus and genu valgus groups with their control groups in two jump tasks. Results: No significant difference was seen between groups in anterior-posterior jumps. Also, significantly higher dynamic postural index was found in the genu varus group compared to its control group in medial – lateral jump tasks (p 0.05). Conclusion: The results showed that genu varus may decrease the dynamic balance. It seems that athletes with genu varus may benefit from some programs to increase their balance during dynamic activity like medial-lateral jumps.   508 The effect of acute circuit resistance exercise on plasma concentration of Brain-Derived Neurotrophic Factor (BDNF) in young men Alizadeh R k Tahmasebi w l Rezaei Nejad R m Salehpour M n Sheikhi S o k Department of Physical Education & Sports Sciences, School of Literature and Humanities, Ilam University, Ilam l Department of Physical Education and Sports Sciences, Razi University, Kermanshah m Department of Physical Education and Sports Sciences, Mazandaran University, Babolsar n Department of Physical Education and Sports Sciences, Shahid Rajaee University, Tehran o Department of Sports Science, Shahid Beheshti University, Tehran 1 12 2017 19 4 30 37 25 02 2017 17 02 2018 Background: Neurotrophins belong to a small group of growth factors family and Brain-Derived Neurotrophic Factor (BDNF) as one of the most active forms of them is widely distributed in mammalian brain and also can be found in plasma and platelets. The aim of this study was to investigate the effect of acute circuit resistance exercise on plasma BDNF concentration in young healthy men. Materials and methods:  In this semi experimental study, twelve young healthy men (age 22.1±2.1 y, height 176.2±6.5 cm, and weight 69.0±8.2 kg) were selected and after familiarization sessions and determining of maximal strength (1-RM), referred to the laboratory after both sessions of exercise or control. The circuit resistance exercise was performed at an intensity corresponding to 55% of 1-RM, consisted of three sets of 15 repetitions and two minutes rest between them. Blood samples from antecubital vein were collected at before, immediately after, after one hour recovery, and next morning after the exercise session. Data were analyzed with ANOVA method with repeated measure at p<0.05 level. Results: The results showed that circuit resistance exercise led to significant increase in levels of BDNF immediately after the exercise (p=0.001), but no significant changes were found in BDNF levels at one hour recovery and next morning after the exercise sessions. Conclusion: According to the results of this study, it seems that acute circuit resistance exercise is strong stimulus for the transient increase in plasma BDNF. Therefore, as the result of the beneficial effects of BDNF, this increase could be effective on brain health.   472 Military Psychiatry Effectiveness of resilience training on stress and psychological well-being of nurses in a military hospital in Kerman jamshidi eini A p Razavi Vida'sadat p Sayed Alshohada Police Hospital, Kerman Department of Psychology, Islamic Azad University, Kerman 1 12 2017 19 4 38 44 26 11 2016 17 02 2018 Background: Nursing is a stressful career which can lead to negative consequences such as increased stress and reduced psychological well-being. So, nurturing capabilities such as resilience to deal with the consequences or preventing them can be helpful in this context. This study aimed to determine the effectiveness of resilience training on the level of stress and psychological well-being of nurses. Materials and methods: This study was a quasi-experimental survey consisting of pre- and post- test, and control group. The study was conducted on 220 nurses of a military hospital in Kerman. Among them, 30 nurses who gained low score regarding the Ryff Scales of Psychological Well-Being (1989)  and high score in Perceived Stress Scale (by Sheldon Cohen; 1983) were selected and assigned into two experimental (n=15) and control (n=15) groups. The experimental group underwent resilience training program according to Henderson's theory for 8 sessions of 90 minutes. The control group received no intervention. Results: The analysis showed that resilience training had a significant effect on stress level (F=4.23) and psychological well-being (F=5.27) of nurses. Conclusion: The results of the current study showed the significant effect of cognitive-based trainings such as resilience, training on the subsidence of stress and improvement of psychological well-being of different strata in the society, especially people with stressful jobs.   499 Assessment of the density and type of the bio-aerosols associated with nosocomial infection in different wards of the selective AJA hospitals in Tehran Rafiee A pesarakloo vida Hoseini Mohammad Shabani Hosein Shahedi A 1 12 2017 19 4 45 52 31 01 2017 17 02 2018 Background: Evaluation of the type and concentration of microorganisms in the air of a hospital can be an indicator of whether such environments are clean or not, and also to be considered as a source of nosocomial infections. The aim of this study was to identify the type and concentration of Bio-aerosols associated with nosocomial infections in different wards of selected AJA hospitals in Tehran. Materials and methods: In a cross-sectional and descriptive- analytical study 120 bacterial and 120 fungal samples were collected from the operation rooms, Intensive Care Units (ICUs) and Infectious diseases wards of two studied hospitals (A and B). A passive indoor environment sampling was carried out within 120 days, once every six days. Results: The average concentration of bacteria in the air of A and B hospitals were 84 and 212 CFU/m3, respectively. Also, the Average concentration of fungal species of A and B hospitals were was 80 and 85 CFU/m3, respectively. The dominant fungal species of these hospitals were Cladosporium (25%) and Aspergillus niger (28%), respectively. Also, Staphylococcus epidermidis was determined as the dominant bacterial species in both hospitals. Significant linear correlation existed between population density and concentration of bio-aerosols. Conclusion: According to the results of this study, bacterial and fungal bio-aerosol concentrations in the studied hospitals were higher than the existing standards and it indicates the low efficiency of the ventilation system in these hospitals.   623 Aerospace Medicine Are flight staffs at higher risk for breast cancer? Ziyari K Rahmani O Eslami R 1 12 2017 19 4 53 68 25 01 2018 27 01 2018 Background: Several studies have shown that there is an increased risk of breast cancer among flight attendants. However, the results of epidemiological studies have not been consistent with this issue. We conducted a brief overview on existing studies on the presence of breast cancer in flight staffs. Materials and methods: A review of databases such as PubMed, Scopus, Embase, Google,Scholar, and ... for related observational studies was undertaken until October 2017. The following keywords were used individually and in all possible various combinations: “breast cancer”, “flight staffs”, and “aerospace medicine”. Results:  The incidence of breast cancer among female flight attendants is higher than normal population. However, no study showed a high mortality rate from breast cancer in this group. Night-time rhythm disturbances due to night shift and changes in time zones which both lead to melatonin disturbances and also exposure to cosmic rays were likely to increase this risk. The results did not differ significantly from year of publication, geographical area, and study quality. Conclusion: Several observational studies and also meta-analyzes showed that the flight group had a higher risk than the normal population for breast cancer. Studies with larger sample sizes are required based on the different population and taking into account all the involved factors.   624 Designing of electronic records for patients admitted to the women ward of Imam Hossein Hospital (Phase I) farzaneh F kiandost M Noghabaei G Hosseini M 1 12 2017 19 4 69 78 25 01 2018 27 01 2018 Background: The electronic data recording technology is used in many developed countries to provide a better service to patients.
