Vitamin D deficiency is associated with cardiovascular and metabolic diseases. Cardiovascular diseases, in turn, are responsible for mortality of patients with type 2 diabetes (T2D). We investigated whether a single parenteral dose of 25(OH) Vit D could improve the endothelial function in T2D patients with ischemic heart disease. A randomized, placebo-controlled, and double-blind trial was perf...

we have performed density functional theory investigations on the adsorption properties of ammonia molecule on the undoped and n-doped tio2 anatase nanoparticles. we have geometrically optimized the constructed undoped and n-doped nanoparticles in order to fully understand the adsorption behaviors of ammonia molecule. for tio2 anatase nanoparticles, the binding site is preferentially located on...

Understanding ultracold collisions involving molecules is of fundamental importance for current experiments, where inelastic typically limit the lifetime molecular ensembles in optical traps. Here we present a broad study optically trapped RbCs with one another, reactive Rb atoms, and nonreactive Cs atoms. For experiments alone, show that by modulating intensity trap, such spend 75% each modula...

On the basis of first-principles calculations, we demonstrate the potential application of silicene as a highly sensitive molecule sensor for NH3, NO, and NO2 molecules. NH3, NO and NO2 molecules chemically adsorb on silicene via strong chemical bonds. With distinct charge transfer from silicene to molecules, silicene and chemisorbed molecules form charge-transfer complexes. The adsorption ener...

The 1998 Nobel Prize in Physiology or Medicine recognized the great contributions of Robert Furchgott, Louis Ignarro, and Ferid Murad through “their discoveries concerning nitric oxide as a signaling molecule in the cardiovascular system.” Furchgott’s earlier work describing a vasodilatory factor that was activated by acetylcholine acting on an intact endothelium not only set the stage for subs...

Ruthenium (Ru) complexes have been studied as promising anticancer agents. Ru nitrosyl complex (Ru-NO) is one which acts as a pro-drug for the release of nitric oxide (NO). The Ru-aqueous complex formed by the exchange of NO for a water molecule after NO release could also possess therapeutic effects. This study evaluates the influence of iontophoresis on enhancing the skin penetration of Ru-NO...
