background: taxol is one of the most important anti-cancer drugs, which is obtained from yew trees (taxus sp.). t+he fist step in side chainassembly of taxol is catalyzed by phenylalanine aminomutase, which converts α-phenylalanine to β-phenylalanine.objectives: in this study, for the fist time, we report on the cloning, preliminary expression and characterization of a full-length gene andcdna ...
BACKGROUND Drug-eluting stents reduce restenosis and reintervention rates but are complicated by stent thrombosis, which may be related to polymer coating. The NEVO sirolimus-eluting coronary stent (NEVO SES) is designed to improve long-term percutaneous coronary intervention safety by combining sirolimus release from reservoirs with bioabsorbable polymer to reduce spatial and temporal polymer ...
OBJECTIVE At 4-year follow-up, paclitaxel-eluting stents (PES, TAXUS) have demonstrated clinical effectiveness in reducing restenosis without increasing death or myocardial infarction. Concerns remain with all drug-eluting stents, however, regarding potential interference with long-term healing, particularly in zones with adjacent stent overlap due to theoretical doubling in both drug release a...
BACKGROUND Early clinical studies demonstrated the feasibility of local paclitaxel delivery in reducing restenosis after treatment of de novo coronary lesions in small patient populations. METHODS AND RESULTS We conducted a randomized, double-blind trial of 536 patients at 38 medical centers evaluating slow-release (SR) and moderate-release (MR) formulations of a polymer-based paclitaxel-elut...
AIMS The purpose of this study was to evaluate the Genous(TM) endothelial progenitor cell capturing stent vs. the Taxus Liberté paclitaxel-eluting stent in patients with de novo coronary lesions with a high-risk of coronary restenosis. METHODS AND RESULTS We randomly assigned 193 patients with lesions carrying a high risk of restenosis to have the Genous stent or the Taxus stent implanted. Le...
BACKGROUND Intracoronary polymer-based stent delivery of paclitaxel has been shown to be effective in reducing restenosis in simple coronary lesions, but the evidence base for contemporary use in longer, more complex coronary stenoses is lacking. METHODS AND RESULTS TAXUS VI is a prospective, multicenter, double-blind, randomized trial assessing clinical and angiographic outcomes of the TAXUS...
OBJECTIVES The aim of this study was to compare the effects of systemic prednisone in combination with a bare-metal stent (BMS) or a paclitaxel-eluting stent (Taxus, Boston Scientific Corp., Natick, Massachusetts) on neointimal inhibition and vessel healing in an atherosclerotic rabbit model. BACKGROUND Inflammation plays a critical role in neointimal formation after coronary artery stenting....
ith great interest I read the report by Weissman et al. (1) regarding ntravascular ultrasound (IVUS) analysis of polymer-based aclitaxel-eluting stents. The investigators stated in the text that positive remodeling assessed as the absolute increase in the xternal elastic membrane volume over time tended to be slightly ore prominent with the TAXUS stent (7.66 48.64 mm vs. 12.29 36.05 mm, respect...
Today, drug-eluting stents (DES) are the standard stenting procedure in the USA and in Switzerland. The objective of this analysis is to answer the two questions: what clinically relevant data regarding DES have been published, and is there a clinically relevant difference between the Cypher and the Taxus stents? Twenty-two randomized, controlled studies with a total of 11,118 patients were ide...
AIM To use an indirect comparisons approach and conduct a cost analysis comparing four drug-eluting stents (DES) from a United States (US) payer (i.e., fixed-fee reimbursement) perspective. METHODS AND RESULTS Studies were chosen that randomised two or more DES in diabetic patients. A one-year target lesion revascularisation (TLR) risk for Taxus was first derived. Risk Ratios (RRs) for each D...
