BACKGROUND: Sleep deprivation resulting from night shifts, is a major cause of burnout among physicians. Exogenous melatonin may improve sleep quality in night-shift workers. The study aims to compare the effectiveness of melatonin versus placebo on sleep effi ciency in emergency medicine(EM) residents. METHODS: A randomized, double-blind, replicated crossover trial was performed on EM residents. This study consisted of 4 phases within a month with intervention periods of 2 nights and washouts of 6 days. In our study, EM residents had nine-hour shifts on 6 consecutive days, 2 mornings, 2 evenings and 2 nights and then 2 days off. At the end of shifts' cycle, 24 EM residents were given 3 mg melatonin or placebo(12 in each arm of the study) for 2 consecutive nights after the second night shift with crossover to the other arm after a six-day off drug. This crossover intervention was repeated for two more another time. Finally, we created 48 cases and comparisons in each arm. Different items related to sleep quality were assessed and compared both within the same group and between the two groups. RESULTS: In the melatonin group, daytime sleepiness(calculated by Karolinska Sleep Scale) had a signifi cant reduction after taking the second dose of drug(P=0.003) but the same result was not observed when comparing the 2 groups. Mood status(calculated by Profile of Mood States) showed no remarkable difference between the 2 groups. CONCLUSION: Melatonin might have a limited benefi t on sleep quality in EM residents working night shifts.

Energy Gain Investigation in Fast Ignition ICF with Electron Ignition Beam by Changing Fuel Characteristics

引用

Chinese Physics Letters 2014年第2期31卷 34-36页

作者： Moosavi Mohadeseh Ahmadi masoume Ghasemizad Abbas Department of Physics University of Guilan Rasht Iran

Fast ignition is a method in inertial confinement fusion （ICF） in which an ignition spark in pre-compression fuel is formed by an ultra-intense laser beam. In applying this method, a hot spot is built by relative electrons which are produced by the ultra-intense laser beam. For a better understanding, a fuel energy gain curve based on density is drawn and it can be observed that the ignition by an electron beam has the maximum energy gain. The maximum energy gain has been observed in equimolar DT fuel with a density of 500g/cma and in fuel with tritium （10%） with a density of 1000g/cm^3.

Previously we have determined the dilute mixture transport properties of slightly polar fluorocarbons using the inverted intermolecular potential energies(Ind. Eng. Chem. Res. 45(2006) 9211–9223). In the present paper, the corresponding states correlations for reduced viscosity collision integrals were employed to obtain effective unlike interaction potential models for dilute binary mixtures of highly polar molecule ammonia with noble *** inverted potentials were fitted to the Morse–Spline–van der Waals(MSV), model potential. The method of least-squares fitting was then applied to identify best consistence force parameters for each ammonia-noble gas mixture, taking advantage of experimental viscosities, diffusion coefficients and thermal *** proposed potential models were compared with those obtained from other sources, in order to assess the extent of their *** potentials were later employed to calculate transport properties of the studied mixtures. Then, results were compared with those reported in the literature, which led to the acceptable agreement.

Stromal vascular fraction combined with silicone rubber chamber improves sciatic nerve regeneration in diabetes

引用

Chinese Journal of Traumatology 2015年第4期18卷 212-218页

作者： Rahim Mohammadi Negin Sanaei Sima Ahsan masoume Masoumi-Verki Fatemeh Khadir Aram Mokarizadeh Department of Surgery and Diagnostic Imaging Faculty of Veterinary Medicine Urmia University Urrnia 57153 1177 Iran Department of Pathology School of Veterinary Medicine Shiraz University Shiraz Iran Department of Immunology Faculty of Medicine Kurdistan University of Medical Sciences Sanandaj Iran

Purpose:To study the effects of transplantation of characterized uncultured stromal vascular fraction (SVF) on sciatic nerve regeneration.Methods:A 10-mm sciatic nerve defect was bridged using a silicone conduit filled with SVF. In control group, silicone conduit was filled with phosphate-buffered saline alone. In sham-operated group, the sciatic nerve was only exposed and manipulated. The regenerated nerve fibers were studied 8 and 12 weeks after surgery.Results:Behavioral and functional studies confirmed faster recovery of regenerated axons in SVF transplanted animals than in control group ( p < 0.05). Gastrocnemius muscle mass in SVF transplanted animal was found to be significantly more than that in control group. Morphometric indices of the regenerated fibers showed the number and diameter of the myelinated fibers to be significantly higher in SVF transplanted animals than in control group. In immunohistochemistry, the location of reactions to S-100 in SVF transplanted animals was clearly more positive than that in control group. Conclusion:SVF transplantation combined with silicone conduit could be considered as a readily accessible source of stromal cells that improves functional recovery of sciatic nerve. It may have clinical implications for the surgical management of acute diabetic patients after facial nerve transection.

Detection of Point Sound Source Using Beamforming Technique in Complex Environments

引用

Open Journal of Acoustics 2018年第2期8卷 23-35页

作者： Navid Nassaji masoume Shafieian Department of Media Engineering IRIBU University Tehran Iran

Detection and localization of acoustic events in an environment are important to protect the military and civilian installations. While there are finite paths of wave propagation in simple or low reverberant environments, in complex environments (e.g. a complex urban environment) obstacles such as terrain or buildings introduce multipath propagations, reflections and diffractions which make source localization challenging. Therefore, numeric results of simulated models (simplified and Fort Benning urban models) of 3D complex environments can highly help in real applications. Some of the conventional beamformer algorithms have been used in order to localize point sound source. Analyzing results shows that MRCB beamformer has better performance than others in this issue and its accuracy superiority is more than 3 m in simplified urban model and 5 m in Fort Benning urban model with respect to the SOC. Moreover, due to possible uncertainties between the numerical model and the actual environment such as squall effect, temperature gradient etc., sensitivity of the beamformers to temperature gradient is investigated which shows higher robustness of SOC beamformer than the MRCB beamformer. According to the results, due to gradient temperature uncertainty the accuracy degradation of the SOC is about 1m while in MRCB it alters from 0.5 m to 20 m approximately at all SNRs. COMSOL Multiphysics has been used to numerically simulate the environment of wave propagation.
