The aim of this study was to investigate the relationships of emotional expressiveness, positive and negative affect with dark triad personality traits. Materials and methods: In this descriptive correlational study, 300 students based on multi-stage cluster sampling from the Urmia University were selected. Then, in order to examine the goals and hypotheses of the study, dark triad traits scale, emotional expressiveness questionnaire, and positive affect and negative affect scale were distributed to the participants. Collected data were analyzed by descriptive indicators, correlation coefficients, simultaneous multiple regression, and independent t-test. Results: Our findings showed that there were negative relationships between most components of emotional expressiveness and all three traits Machiavellianism, narcissism, and psychopathy which were significant for psychopathy and Machiavellianism traits (p<0.05). Also, all dark triad traits had significant positive correlations with positive and negative affect (p<0.01). In addition, women and men had a significant difference in dark personality traits and men had higher scores in Machiavellianism and positive affect, while women showed higher scores in emotional expressiveness components. Conclusion: People with high scores on the traits of Machiavellianism and psychopathy, are more likely to show defects in expressing and understanding of emotional information. It seems that women are more sensitive emotionally, and more prone to emotion. Personality Disorders Affects Emotions 2016 7 01 11 18 http://ebnesina.ajaums.ac.ir/article-1-391-en.pdf

The aim of this study was to examine the effect of aerobic exercise on the levels of parathormone (PTH), alkalin phosphatase (ALP), and calcium (Ca) in untrained obese men. Materials and methods: Totally, 22 untrained obese men (33.9±3.6 years old; body mass index: 32.65±3.42 kg/m2) volunteered to participate in our study. They were randomly divided into two experimental (n=12) and control (n=10) groups. The experimental group performed a training program for 12 weeks (three sessions per week and each session lasted 80 minutes with the intensity of 60-80% maximum heart rate). The control group didn’t participate in any intervention program. For measuring biochemical factors (ALP. Ca and PTH), blood samples were taken from each group. . Finally, t-test was used for the comparison of intergroup mean changes. Results: The study findings showed that there was a significant increase in PTH and ALP in the experimental group compared to the control group (p<0.001). However, no significant difference was seen in the concentration of Ca in the experimental group. Furthermore, there was a significant decrease in the fat percentage, body mass index, and weight in the experimental group (p<0.001). Conclusion: Results showed that a three-month aerobic exercise with the intensity of 60-80% of maximum heart rate causes a significant change in markers of bone metabolism in the obese men. These changes can indicate an increase in calcium absorption and may be the effects of anabolic of PTH and exercise.

Because of aptamers were able to overcome the weakness of antibodies, so they are a proper substitute for antibodies. These molecules usually are prepared in vitro by combinatorial chemistry techniques which are gradually separated from combined libraries by a laboratory process called SELEX. SELEX round was achieved through repeated consecutive steps that include selection process (binding, separation, and washing), proliferation, and conditioning. Materials and methods: This case study is a review on the aptamers and comparing them with antibodies and also their application as recognition agent. Results: Due to the high stability and high affinity of aptamers, they are used as biosensor in diagnosis and treatment, laboratory diagnostic kits, diagnostic approaches in the bioterrorism, and drug delivery. Conclusion: Applications and capabilities of aptamers and aptasensors showed the importance of research and study of them in different fields of science, specially related to military services such as identifying remaining of chemical weapons, identifying the agent used in bioterrorism, biological threats, viruses, toxins, and pathogens.

The aim of this study was to determine the ergonomics characteristics among computer users in the Baqiyatallah Hospital based on transtheoretical model-stage of change. Materials and methods: This descriptive-analytical study was conducted on 115 computer users who worked by computers more than 20 hours per week. Data was collected using the stage of change questionnaire and to assess the ergonomics characteristics, Rapid Office Strain Assessment (ROSA) was used. Data was analyzed through descriptive and analytical statistics by SPSS software. Results: Our findings about the stages of change showed that pre-contemplation, contemplation, preparation, action, and maintenance stage was seen in 31.3%, 20%, 15.7%, 10.4%, and 22.6% of users, respectively. In addition, ROSA showed that the ergonomics characteristics were at acceptable, warning, and intervention level in 2.6%, 53%, and 44.3% of participants. Chi square test indicated a significant relationship between educations and stages of change (p=0.030). As a result, 67% of users were in the inactive group (pre-contemplation, contemplation, and preparation); while based on ROSA, 97.4 % were at warning level and intervention. Conclusion: Generally, the majority of users were in the inactive group (pre-contemplation, contemplation, and preparation) and the ergonomics characteristics were at warning and intervention levels. Therefore, in this regard, it is suggested the appropriate educational interventions. Ergonomics Occupational Health Risk Assessments 2016 7 01 54 57 http://ebnesina.ajaums.ac.ir/article-1-353-en.pdf
