Background & Aims : Aging and the loss of endogenous estrogen production after menopause are accompanied by increases in blood pressure and endothelial dysfunction. Exercise training improves endothelial function in patients with hypertension. The aim of this study was to examine the effect of aerobic training on some markers of endothelial function in hypertensive postmenopausal women. M...
conclusions vancomycin nephrotoxicity is common but usually reversible and has readily manageable adverse effect. urine kim-1 was not more accurate than serum or urine creatinine in detecting vancomycin nephrotoxicity in our study population. results thirteen out of the 52 recruited patients (25%) developed nephrotoxicity, with a mean ± standard deviation onset of 11.46 ± 7.56 days. furosemide ...
Since FOX-7 (1, 1-diamino-2, 2-dinitroethylene) is a relatively new energetic material, little is known about its physical and chemical properties. Therefore, first-principles quantum chemical calculations are used to predict the energies of atoms of FOX-7. Under gentle heating (thermolysis) is likely to cause hydrogen transfer between molecules, producing highly reactive chemical species. Conv...
an attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.
The adsorption of hydrogen sulfide molecule on undoped and N-doped TiO2/Au nanocomposites was investigated by density functional theory (DFT) calculations. The results showed that the adsorption energies of H2S on the nanocomposites follow the order of 2N doped (Ti site)>N-doped (Ti site)>Undoped (Ti site). The structural properties including bond lengths, angles<span id="...

تا کنون یون های واکنشگر مختلفی برای یونیزاسیون شیمیایی در روش یونش نرم مورد استفاده قرار گرفته اند که این یون ها شامل +ch5+، nh4+، no و+h3o می باشند. از بین این یون ها +no و +h3o که با اجزاء هوا واکنش نمی دهند ولی با بیشتر گونه های آلی و معدنی واکنش سریعی دارند دارای اهمیت می باشند. یون واکنشگر معمول در دستگاه طیف سنج تحرک یونی، +h3o است. در این پایان نامه یون +no بعنوان یون واکنشگر جدید و اصلی...
