Elution Countercurrent Distribution

Analytical Biochemistry, 1987
The single withdrawal technique, here called elution countercurrent distribution, was applied for the first time on aqueous two-phase systems. The modifications necessary for elution countercurrent distribution of a thin-layer countercurrent distribution apparatus are described.

Drug-Eluting Stents

Seminars in Interventional Radiology, 2022
AbstractEndovascular revascularization strategies have advanced tremendously over the years and are now often considered first line for treatment of peripheral arterial disease. Drug-eluting stents (DESs) have been developed as one of the tools to overcome the limitations of elastic recoil and neointimal hyperplasia observed with balloon angioplasty ...

Paclitaxel-eluting Stents

Future Cardiology, 2006
Percutaneous coronary intervention and stent implantation is rapidly becoming the most commonly used form of revascularization. The long term results of this procedure are limited by restenosis which is a phenomenon predominantly caused by proliferation of smooth muscle cells.

Drug-Eluting Stents

Annual Review of Medicine, 2004
Advances in catheter and stent design have made stent implantation the standard coronary angioplasty procedure. Unfortunately, in-stent restenosis continues to plague this procedure, with the optimum binary restenosis rates reaching ∼10% to 20%. In the past few years, it has become clear that in-stent restenosis is largely due to the migration and ...

High speed counter current chromatography: Overview of solvent-system and elution-mode

Journal of Liquid Chromatography & Related Technologies, 2018
High speed counter current chromatography (HSCCC) utilizes a liquid stationary-phase and, hence, does not suffer from irretrievable adsorption associated with conventional chromatography procedures. It is a good alternative for such techniques because of

Hyperfast Flow-Field Thermal Gradient GC/MS of Explosives with Reduced Elution Temperatures.

Analytical Chemistry, 2018
Hyperfast GC/MS below 60 s of measurement time has been used for the measurement of explosives. The new flow-field thermal gradient GC (FF-TG-GC) utilizes a modified transport process of the explosives at lowered temperatures.

Drug Eluting Balloons

Techniques in Vascular and Interventional Radiology, 2010
Ever since the first percutaneous transluminal angioplasty (PTA) was carried out in Switzerland in 1977, restenosis remains a major drawback of this minimally invasive treatment intervention. Numerous attempts to increase vessel patency after PTA have included systemic medications and endovascular brachytherapy, but these techniques have not met our ...
