let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
Deep eutectic solvents (DESs) have emerged as promising green solvents, due to their versatility and properties such high biodegradability, inexpensiveness, ease of preparation negligible vapor pressure. Thus, DESs been used sustainable media catalysts in many chemical processes. On the other hand, lignocellulosic biomass an abundant source renewable carbon has received ample interest for produ...
BACKGROUND Drug-eluting stents (DESs) were considered as ground-breaking technology promising to eradicate restenosis and the necessity to perform multiple revascularization procedures subsequent to percutaneous coronary intervention. Soon after DESs were released on the market, however, there were reports of a potential increase in mortality and of early or late thrombosis. In addition, DESs a...
In percutaneous coronary interventions, drug-eluting stents (DESs) have reduced the risk of restenosis and repeat revascularization compared with bare-metal stents. The secondgeneration DESs with thinner stent struts have improved safety and efficacy compared with the first-generation DESs and has been associated with a reduced risk of late stent thrombosis. The persistence of polymer material ...
Polymer-coated drug-eluting stents (DESs) have become the treatment of choice in most patients undergoing percutaneous coronary interventions. Although these stents are effective in the sense that they reduce the restenosis rate and the need for repeat intervention by 70% compared with bare-metal stents, concerns have been raised about a series of risks closely related to the metal mesh of the ...
Deep eutectic solvents (DESs) are a valid alternative to common organic and ionic liquids (ILs) as solvent media for oxidation reactions.
Although the angiographic rates of in-stent restenosis (ISR) at later months have reduced dramatically with the introduction of drug-eluting stents (DESs), some patients with ISR after implantation of DES present with acute coronary syndrome (ACS). Here, we sought to identify parameters influencing the likelihood of restenosis with ACS presentation after DES implantation. Stented patients (n=3,...
