Academicians are identified with their papers and expertise in writing scholarly articles, either for promotion or for satisfying their prestige. Iranian academic members are expected to win a justifiable stance by the quality and quantity of their publications and presentations. Regrettably through pervious studying about second language writing, any studies haven’t been dedicated to the style of writing articles, which are used by academic members. Former studies on second language writing indicate that style in academic paper writing is most likely ignored. The purpose of this study is to explore the role of mind translation strategy among Iranian academic members for expressing their own opinion through writing second language academic papers. The present paper has based its hypothesis on three levels of strategies, effective in writing academic papers, namely: 1-Do Iranian academicians follow specific strategies in writing their academic papers? 2-What role does translation play as a strategy in their writing academic papers? 3-Do they feel a need for a strategy shift in their academic paper writing? Data elicited based on survey and corpora analysis in form of CBDTS- on micro and macro levels, are put into matrices and their analyses are supportive of academicians’ reliance on different types of mental translation use and their shift toward authentic writing after receiving feedback from their reviewers. © Australian International Academic Centre, Australia.

Introduction: Environmental pressure changes with depth may lead to changes in various hormone levels in the body. Of interest are the so-called stress hormones, such as cortisol. Other factors altering cortisol levels are anxiety, exercise and cold. We investigated serum cortisol changes after air scuba dives in 24–27ºC open water up to a depth of 30 metres. Method: Ten, experienced, male divers participated in the study. Four dives, to depths of 1, 10, 20 and 30 metres’ sea water (msw) for 20 minutes bottom time, at rest, were conducted at about 1000 h on four consecutive days in the Persian Gulf. Before diving and soon after surfacing, approximately 5 ml blood was drawn from a right antecubital vein for serum cortisol assay, using a radioactive immunoassay technique. Repeated measures was used to analyse cortisol changes with depth. Results: There were significant differences in the pre-dive cortisol levels (df = 1, F = 5.978, P < 0.037) and post-dive levels (df = 1, F = 34.567, P < 0.001). Cortisol levels increased with immersion irrespective of depth compared to pre-dive levels, whilst they were further significantly raised after dives to 10 m (mean 312.6 nmol∙L-1), 20 m (mean 299.1 nmol∙L-1) and 30 m (mean 406.7 nmol∙L-1) depth compared to levels after the 1 m dive (mean 189 nmol.L-1). Conclusion: The observed changes in serum cortisol were considered to be the result of the physiological effects of immersion combined with increased environmental pressure, rather than resulting from anxiety, heavy exercise or cold stress. © 2014, South Pacific Underwater Medicine Society.

Objective(s): High-intensity interval training (HIIT) increases energy expenditure and mechanical energy efficiency. Although both uncoupling proteins (UCPs) and endothelial nitric oxide synthase (eNOS) affect the mechanical efficiency and antioxidant capacity, their effects are inverse. The aim of this study was to determine whether the alterations of cardiac UCP2, UCP3, and eNOS mRNA expression following HIIT are in favor of increased mechanical efficiency or decreased oxidative stress. Materials and Methods: Wistar rats were divided into five groups: control group (n=12), HIIT for an acute bout (AT1), short term HIIT for 3 and 5 sessions (ST3 and ST5), long-term training for 8 weeks (LT) (6 in each group). The rats of the training groups were made to run on a treadmill for 60 min in three stages: 6 min running for warm-up, 7 intervals of 7 min running on treadmill with a slope of 5° to 20° (4 min with an intensity of 80-110% VO2max and 3 min at 50-60% VO2max), and 5-min running for cool-down. The control group did not participate in any exercise program. Rats were sacrificed and the hearts were extracted to analyze the levels of UCP2, UCP3 and eNOS mRNA by RT-PCR. Results: UCP3 expression was increased significantly following an acute training bout. Repeated HIIT for 8 weeks resulted in a significant decrease in UCPs mRNA and a significant increase in eNOS expression in cardiac muscle. Conclusion: This study indicates that Long term HIIT through decreasing UCPs mRNA and increasing eNOS mRNA expression may enhance energy efficiency and physical performance. © 2016, Mashhad University of Medical Sciences.

Rapid adsorption of Triamterene using multi-walled carbon nanotube (MWCNT) and single-walled carbon nanotube (SWCNT) was well investigated and elucidated. The impact of influential variables such as temperature, amount of adsorbent, initial drug concentration, contact time was modeled using multiple linear regression (MLR) and artificial neural network (ANN) and the influential variables were optimized using genetic algorithm (GA). The adsorption equilibrium and kinetic data was well fitted and found to be in good agreement with the Langmuir monolayer isotherm model and pseudo second order kinetics mechanism. The maximum adsorption capacity of SWCNT and MWCNTs for the removal of Triamterene was found to be 25.77 mg g- 1 and 33.14 mg g- 1 respectively. The negative value of adsorption enthalpy (ΔH°) reveals towards the exothermic nature of the adsorption process. Based on the results comparison of the proposed models, results revealed that the applicability of the ANN model is more appropriate in comparison to the MLR model for predicting the adsorption efficiency of the process. The coefficient of determination (R2) of 0.980 and mean squared error (MSE) of 0.002 for adsorption on SWCNT 0.986 and 5.4e-04 on MWCNT were obtained, respectively using the optimal ANN model. © 2016 Elsevier B.V.

Background and Objectives: Despite the wide spread use of zinc oxide nanoparticles (Nano zinc oxide) in the medical and industry, a comprehensive study has been done on the effects of neuropsychological and cognitive its related processes. Considering the oxidative effects of nanoparticles, there has been a great challenge on the way to their medicinal use. The purpose of this study was to investigate the effect of acute application of Nanozinc oxide on memory processes in the presence and absence of vitamin C as an antioxidant in the adult male rats.Methods: Adult male wistar rats (200-250g) were divided into groups with 7 in each including saline, three groups received Nano zinc oxide (1.25, 2.5 and 5mg/kg), three groups received vitamin C (30, 60, 120mg/kg) alone and three groups received vitamin C and Nanozinc oxide in combination. Memory was assessed by Step Down device after teaching using passive avoidance learning.Results: It was revealed that in all three doses of Nano zinc oxide there was a significant loss of memory (P <0.001and P <0.01) while no change in locomotor activity. Vitamin C as antioxidants, at doses of 60 and 120 mg impaired memory and in 30 mg was ineffective. Ineffective dose of vitamin C could not improve memory deficit resulting from the Nano zinc oxide.Conclusion: Considering the results of this study, acute application of Nano zinc oxide causes significant impairment in long-term memory, and this effect is probably not just due to its oxidative effect. This action mechanism may be effect through change in receptors activity or neurotransmitters releasing which is associated with memory that needs to be investigate further. © 2014 AENSI Publisher All rights reserved.
