زمینه و هدف: پیشرفت در فن آوری اطلاعات و ارتباطات سبب ایجاد نگرش جدیدی در امر آموزش و شیوه های آن شده است؛ به طوری که تغییر رویکرد آموزش به روند آموزش در جهت استفاده از امکانات و منابع الکترونیکی و آموزش مجازی اهمیت بسیاری یافته است. هدف از این مطالعه، بررسی و مقایسه دو روش آموزش مجازی و سنتی در مهارت های کاربردی تکنسین های پارامدیک در اورژانس پیش بیمارستانی بود. روش کار: مطالعه نیمه تجربی حا...
After just simple degassing, dilution, pH adjustment and direct flow injection, characteristic fingerprint spectra of beer samples have been obtained by fast (few seconds) electrospray ionization mass spectrometry (ESI-MS) analysis in both the negative and positive ion modes. A total of 29 samples belonging to the two main beer types (lagers and ales) and several beer subtypes from USA, Europe ...
Electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (ESI-MS/MS) data of a unique family of complexes of nitroso compounds coordinated to pentachloroiridate(III), [Cl5IrN(O)XR]2- (X=NH, S, CH and R=alkyl, aryl) are presented. These novel complexes are obtained by nucleophilic attack of primary amines, thiols. and alkenes to the coordinated nitrosyl. Despite their labi...
Electrospray ionization mass spectrometry (ESI-MS) binding studies between proteins and ligands under native conditions require that instrumental ESI source conditions are optimized if relative solution-phase equilibrium concentrations between the protein-ligand complex and free protein are to be retained. Instrumental ESI source conditions that simultaneously maximize the relative ionization e...
Using electrospray ionization mass spectrometry (ESI-MS), we demonstrate the direct observation of NO attached to the heme moiety in horse heart myoglobin (Mb) and in the Rand â-chains of human hemoglobin (Hb). It was found that a narrow range of ESI-MS conditions conspire to make observation of Fe-NO interactions challenging, and this is presumably the reason why earlier attempts by other rese...
Recently, a novel environmental stress index (ESI) which is composed from commonly used meteorological variables: ambient temperature (T(a)), relative humidity (RH), and solar radiation (SR) was suggested as follows: ESI = 0.63T(a)-0.03RH+0.002SR+0.0054(T(a) x RH)-0.073(0.1+SR)(-1); (degrees C) The purpose of the present study was to evaluate and validate the ESI for hot dry and hot wet climati...
BACKGROUND/PURPOSE One of the most common complications of the peritoneal dialysis (PD) is the infection of the exit site of the peritoneal catheter. The aim of the present study was to evaluate the efficacy of the subcutaneous gentamicin injection around the cuff as a part of routine treatment of the resistant exit site infection (ESI). METHODS If the exit site remains infected after a 2-wee...
از آنجایی که صحنه نبرد یک واقعه تقریباً ناگهانی به همراه و تعداد زیادی مجروح با ضایعات بسیار سطحی تا ضایعات بسیار بحرانی می باشد، تریاژ و تعیین میزان ضایعات و درمان سریع از اهمیت خاصی برخوردار است که اکثر بیماران در مراکز مختلف درمانی از پست امداد تا بیمارستان های صحرایی و نهایتاً بیمارستان های پشت جبهه تحت مداوا قرار می گیرند، لیکن آنچه که دز کنار درمان اورژانس بیماران از اهمیت بیشتری برخوردار ا...
Fatty acids in 42 types of saponified vegetable and animal oils were analyzed by electrospray ionization mass spectrometry (ESI-MS) for the development of their rapid discrimination. The compositions were compared with those analyzed by gas chromatography-mass spectrometry (GC-MS), a more conventional method used in the discrimination of fats and oils. Fatty acids extracted with 2-propanol were...
OBJECTIVES this study aimed to investigate the construct validity and responsiveness of performance-based and self-reported measures of strength, mobility and balance after hip fracture. DESIGN secondary analysis of clinical trial data. SUBJECTS a total of 148 older people undergoing hip fracture rehabilitation. METHODS correlation coefficients assessed construct validity. Internal respon...
