In a consecutive series of 26 previously operated patients diagnosed with cerebral glioma, magnetic resonance spectroscopy (MRS), 2-((18)F) fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET), and perfusion MRI (MRP), were performed at follow-up to distinguish recurrence from radiation necrosis, and to identify tumour upgrading. Discrepancy between techniques was observed in 9 cases...
در این تحقیق قدرت بیمارگری سه ویروس Spodoptera littoralis NPV، Helicoverpa armigera NPV و Spodoptera litura NPV در سه غلظت مختلف 10۲×6، 104×6 و ۱۰۶×۶ OB در میلیلیتر روی لاروهای ۵ روزه کرم برگخوار مصری پنبه (Spodoptera littoralis) در دمای ۲5 درجه سلسیوس روی غذای مصنوعی بررسی شد. بیشترین طول دوره لاروی با 19.7 روز مربوط به ویروس H. armigera در غلظت ۱۰۴×6 OB در میلیلیتر بود که با بقیه تیمارها اخ...
BACKGROUND ECG criteria differentiating Takotsubo cardiomyopathy (TTC) from mainly anterior myocardial infarction (MI) have been suggested; however, this was in small patient populations. METHODS AND RESULTS Twelve-lead admission ECGs of consecutive 200 TTC and 200 MI patients were compared in dichotomized groups based on the presence or absence of ST-elevation MI (STEMI versus STE-TTC and no...
BACKGROUND Because venous ultrasound (US) fails to fully image the calf veins, there is the potential for US gold standard studies to classify patients with calf deep venous thrombosis (DVT) in the nondiseased category, causing bias in test index calculations. A false increase in negative predictive value (NPV) is especially likely because calf DVT false-negative tests will be counted in the nu...
OBJECTIVE To assess the effectiveness of the Veress needle puncture in the left hypochondrium and the accuracy of the tests described for the intraperitoneal correct positioning of the tip of the Veress needle in an unselected population. METHODS Ninetyone patients consecutively scheduled for Videolaparoscopy had the abdominal wall punctured in the left hypochondrium. There were no exclusion ...
BACKGROUND The lack of patient triggering capability during negative pressure ventilation (NPV) may contribute to poor patient synchrony and induction of upper airway collapse. This study was undertaken to evaluate the performance of a microprocessor based iron lung capable of thermistor triggering. METHODS The effects of NPV with thermistor triggering were studied in four normal subjects and...
Corresponding Author: Al-Ashhab Mohamed Sayed Department of Mechanical Engineering, College of Engineering and Islamic Architecture, Umm Al-Qura University, Makkah, Saudi Arabia Email: [email protected] Abstract: As the importance of forward-reverse logistics increases, attention will be focused on parameters which affect Net Present Value (NPV) of the whole system, aiming at considering th...
BACKGROUND The clinical implications of a negative multiplane transesophageal echocardiography (TEE) have not yet been reported. We aim to determine the negative predictive value (NPV) of a negative multiplane TEE in patients with suspected infective endocarditis (IE). METHODS AND RESULTS We identified 83 consecutive patients with suspected IE and negative multiplane TEE from our echocardiogr...
