Abstract
Background and Aim: Prevalence of anabolic steroids (ASs) consumption among bodybuilders has increased progressively. Therefore, the purpose of this study was to evaluate the effect of ASs consumption on C-reactive protein (CRP) in bodybuilders.
Materials and Methods: Sixty healthy men (age: 24/1± 9/1yr weight: 77±10 kg and height: 172±12 cm) participated in the study voluntarily. These subjects were selected from three groups. First group (FG) was bodybuilders who consumed ASs (n=20), second group (SG) was bodybuilders who did not consume ASs (n=20) and third group (TG) were untrained subjects as control (n=20). Blood samples were collected in fasting state (12 hours) at 09:00 for CRP assessment. Strength and volume of the forearm, pectoral major and femur muscles were measured via 1RM test and muscle circumstances, respectively. Speed was assessed by 30m speed test. Analysis of variance test and LSD post-hoc test was used.
Results: FG had significantly greater blood CRP (P<0/05) compared to other groups. However, differences between SG and TG were not significant. Muscle strength, and forearm and femur circumstances were greater in FG than other groups. Furthermore, this was greater in SG than TG. But chest circumstance was greater in FG and SG than TG only. There were no significant differences in speed between groups.
Conclusion: ASs consumption for muscle strength and volume improvement in bodybuilders is accompanied by higher level of CRP (as a cardiovascular risk factor).

Abstract
Background and Aim: Learning basic issues in nursing requires new strategies that can enhance knowledge retention among nurses. This study aimed to determine the effect of lecturing by peer-nurses on critical units nurses’ retaining knowledge of electrocardiogram (ECG) interpretation.
Materials and Methods: In this experimental study, two units (as test and control groups) were selected randomly from among critical care units of Semnan University of Medical Sciences hospitals. First, a pretest was performed on nurses in both groups. Then, the nurses of test group were trained by a peer-nurse how to interpret ECGs. A posttest was performed on the two groups both a week and a year later. Finally, the data were analyzed using Pearson’s correlation coefficient, t-paired and t-tests.
Results: The mean of nurses’ scores of ECG interpretation in pretest was 9.55±2.73 in the test group and 10.82±3.43 in the control group. In the first posttest, mean scores of nurses’ knowledge in test and control groups were 15.27±2.57 and 11.36±3.29, respectively. In the second posttest, nurses’ mean scores in test and control groups were 10.82±4.07 and 11.33±2.95, respectively. There was a significant difference (p<0.05) between the pretest and the first posttest in the test group, but there was no such difference for the second posttest (p>0.05).
Conclusion: Lecturing by peer-nurses can enhance nurses’ knowledge about ECG interpretation in the short run, but it cannot enhance knowledge retention. So it is suggested that other educational methods be used in nurses' in-service training programs designed for ECG interpretation.

Abstract
Background and Aim: Emergency medical services (EMS) staff’s attention level may be affected by various work conditions. This study aims to compare the beginning- and end-of-shift attention levels of Tehran’s pre-hospital emergency staff with those of Semnan Province.
Materials and Methods: This is a descriptive and cross-sectional research study conducted in 2013. In this study, 192 emergency medical technicians (EMT) of Tehran and Semnan Province participated. The research instrument was Bonnardel Attention Level Test. The participants’ attention level was assessed at 10 am and 5 am. The data were analyzed by chi-square test and independent samples t-test.
Results: At 10 am (arrival attention), the average rate of attention level of Tehran’s pre-hospital emergency staff was 0.49±0.25 and that of Semnan Province staff was 0.51±0.23. There was not a significant difference (p=0.58) at that time between the average rate of attention in these two groups. At 5 am (exit attention), however, the average attention level of Tehran’s pre-hospital emergency staff was 0.45±0.25, and of Semnan Province staff was 0.55±0.20. At this time, there was a statistically significant difference (P= 0.044) between the average rate of attention in these two groups.
Conclusion: The means of arrival and exit attention levels in pre-hospital emergency staffs were moderate. Besides, there was no significant difference between the arrival attention levels of the two groups. Therefore, in order to increase the attention level in both groups, it is suggested that the workload and the length of shifts should be reduced for pre-hospital emergency staffs, specially in Tehran.

Abstract
Background and Aim: CT scan as a medical imaging modality delivers high radiation dose to the patients. Since eye and thyroid are two radiosensitive organs in this study, those effective doses were evaluated in brain CT scan. Using TLD as dosimeter.
Materials and Methods: This cross-sectional study was carried out in three selective hospitals in Rasht in September and October in year 2016.TLD was used as personal dosimeter. To measure the effective dose, TLDs were put on the patient’s eyes and thyroid and the mean effective dose was evaluated in brain CT scan. Results were analytical using SPSS software and Anova (P<0.05).
Results: The mean effective doses of eyes and thyroid in three hospitals with codes of H1, H2 and H3 were obtained as 2.66±2.04 mSv and 0.03±0.009 mSv, 1.80±1.11 mSv and 0.03±0.02 mSv, 1.94±0.95 mSv, 0.04±0.01 mSv, respectively. We found significant differences between effective doses of the eyes and thyroid in the three hospitals (p<0.05). Despite the difference in effective doses between right and left sides of eyes and thyroid, we didn't find any other significant differences.
Conclusion: The most important factor affecting patient radiation dose is the way CT scan examination is performed.

Abstract
Background and Aim: Deep and sustainable learning requires a safe and healthy environment. Moreover, paying attention to the intertwined emotional, motivational, cognitive and social processes in the teaching-learning process is vital. Academic achievement motivation and self-regulated learning (SRL) are two important elements in this process that are influenced by the achievement emotions in the learning environment. Therefore, the aim of this study is to evaluate the effectiveness of instructional design model based on control-value theory of achievement emotions (CVT), on academic achievement motivation and self-regulation learning.
Materials and Methods: The research was quantitative and performed by Nonequlment design control group. The statistical population included female second year high school students in Tehran in the academic year of 1997-98, who were selected by multi-stage cluster random sampling in two experimental and control groups. The experimental group was trained according to the instructional design model based on CVT theory and the control group did not receive this training method. The questionnaire of academic achievement motivation and self-regulated learning was administered to the experimental and control groups as pre-test and post-test before and after the implementation of the model. Data were analyzed by inferential and descriptive statistics using SPSS software and multivariate covariance.
Results: The results of univariate analysis of covariance of group effect on the scores of dependent variables show that there is a significant difference between the experimental and control groups in cognitive strategy (F=11/94, P>0/05, η2=0/14), metacognition strategy (F=56/06, P>0/05, η2=0/44), motivational beliefs (F=6/36, P>0/05, η2=0/08) and academic achievement motivation (F=10/69, P>0/05, η2 =0/13).
Conclusion: The result of this study show that the use of instructional design model based on CVT theory has a positive effect on cognitive strategies, metacognition strategies, motivational beliefs and learners' academic achievement motivation.
