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 : Nurses' perception of spirituality can affect the way they behave and communicate with patients in line with spiritual care provision. The present study aims to investigate nurses' perception , capability, and adequacy of training about spirituality and spiritual care in Genaveh hospitals affiliated to Bushehr University of Medical Sciences (BUMS) .
Materials and Methods: A cross-sectional descriptive study was performed among 111 nurses working in BUMS hospitals in 2013. The spirituality and spiritual care scale (SSCRS) was used for data collection, which explores nine aspects of spirituality and spiritual care. Descriptive statistics were used to analyze the data.
Results: The overall spirituality and spiritual care was 3.86 (out of 5). Among the nine aspects of need for spirituality, belief in God had the highest mean score, and beliefs and values had the least mean values. About 78.7 % of the participants were confronted with the patients' spiritual needs. Meanwhile, 74.6 % of them noted that the current training about spiritual care was not sufficient .
Conclusion: Although most participants were able to meet the patients' spiritual needs, most of the nurses did not know enough about the issues related to spiritual care. Therefore, inclusion of spiritual care in nursing curriculum and holding workshops and training courses in this area can be useful.

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: At the present time one of the strategies in vaccine design is generation of fusion proteins containing (including) immunogen of infectious agents and adjuvants. In this study design and construction of E2-fliC fragment as a vaccine candid was conducted by using fliC gene from Salmonella enterica and E2 gene from hepatitis C virus.
Materials and Methods: To prepare the E2-fliC construct, E2 and fliC fragments were first amplified from pBluscript-E2 and pBluscript-fliC, respectively by PCR method. To generate pcDNA-E2-fliC plasmid, E2 was subcloned into plasmid pcDNA3.1 (+) which was extracted from DH5α cells. The fliC sequence was then cloned into the pcDNA3.1-E2. To evaluate the expression of E2-fliC construct, it was inserted into the pEGFP-N3 expression vector. Then COS-7 cells were transfected with pEGFPN3- E2-fliC to evaluate the expression of the fusion protein by observation of the EGFP signal under the fluorescence microscope.
Results: By development of GFP fluorescent using fluorescence microscopy the most expression of E2-fliC construct was observed at 24h after transfection. The accuracy of the recombinant plasmid pcDNA-E2-fliC was confirmed by PCR, restriction enzymes and DNA sequencing.
Conclusion: Our findings suggest that E2-FliC fusion protein has expressed efficiently and most likely similar to HCV E2 protein induces immune system of mice after their immunization with pcDNA-E2-fliC.

Abstract
Background and Aim: Inactivity increases the risk of chronic diseases. The aim of the present study was to investigate the acute changes in Normetanephrine and glucose in boxing with Kinect Xbox with and without blood flow restriction as an alternative to aerobic exercise during quarantine in young non-athletes.
Material and Methods: Fourteen healthy non-athlete individuals with a range of 20 to 40 years of age were randomly and purposefully selected. And on two different days with and without restriction of blood flow, they played boxing with Xbox 360 for 20 minutes. Blood samples were taken before and immediately after
Results: There was a significant increase in serum Normetanephrine playing compared to before the test in both training groups, but the amount of changes between the two groups with and without blood flow restriction was not significant (P≤0.05). Exergames, in the case of unrestricted blood flow, has a significant effect on glucose, but the restriction of blood flow did not lead to a significant difference in the amount of glucose (P≤0.05).
Conclusion: Exergames provide the necessary stimulus for catecholamine secretion and glucose response, and it is recommended for people with limited blood flow. Further studies are needed on the effect of restricting blood flow as a new training method on video game with movement.
