New surface modification of titanium implant with phospho-amino acid.
The purpose of this study was to investigate a new biochemical surface modification technique for titanium implants using phospho-amino acid. Pure titanium disks were pretreated with 10 N HCl and ultrapure water at room temperature for 30 minutes respectively. Then these disks were modified with either L-threonine (Thr) or O-phospho-L-threonine (P-Thr) at 37 degrees C for 12 hours. X-ray photoe...
متن کاملEvaluation of a novel slow-release paclitaxel-eluting stent with a bioabsorbable polymeric surface coating.
OBJECTIVES We sought to evaluate a new second-generation drug-eluting stent (DES), comprising a slow-release biodegradable polylactide coglycolide (PLGA) polymer and low-dose paclitaxel on a thin-strut cobalt chromium stent platform, in a clinically relevant animal model. BACKGROUND Our previous work demonstrated subacute vascular toxicity and necrosis triggering late excess neointima in pig ...
متن کاملOptimal Stent Expansion by Stent Balloon Multiple Inflation at Nominal Pressure in Resistant Lesions: A New Technique
Introduction: This study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. Materials and Methods: This interventional study was conducted on 39 patients with coronary artery lesions, in whom Zotarolimus-eluting stents (N=20), Paclitaxel-eluting stents (N=11) and other stents (N=8) were deployed four tim...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولStent distortion after sutureless aortic valve implantation: a new complication seen with a novel surgical technique.
In recent years, sutureless aortic valves have grown in popularity. As these valves do not need to be anchored with sutures, shorter cardiac ischaemia and extracorporeal circulation times can potentially be achieved. In addition, the absence of a sewing ring in these valves results in a greater effective orifice area for any given size. Postoperative outcome may be improved using sutureless val...
