BACKGROUND It has been shown that antiproliferative drugs such as paclitaxel lower the amount of intimal hyperplasia after stent implantation. We report the first clinical experience of 7-hexanoyltaxol (QP2)-eluting polymer stent system (QuaDS) implantation for in-stent restenosis. METHODS AND RESULTS Fifteen consecutive patients with elective indication to percutaneous coronary intervention ...
UNLABELLED The objective of this manuscript was to report a case of a patient with extruded pulse generator 3 years after implantation of a spinal cord stimulator system.With the increasing incidence of chronic pain, spinal cord stimulation (SCS) is becoming more commonly utilized by pain physicians. SCS is a generally safe intervention with minimal adverse effects; however, there are risks of ...
OBJECTIVES We sought to examine by angioscopy the neointima formation and thrombogenic potential of the neointima after deployment of a drug-eluting stent (DES). BACKGROUND Late stent thrombosis after DES implantation, a major safety concern, has been associated with poor strut coverage by neointima. Intracoronary angioscopy provides a method for visual evaluation of stent coverage by neointi...
OBJECTIVES Unexplained bleeding events are a severe complication in patients with left ventricular assist devices (LVADs). Platelet dysfunction and acquired von Willebrand syndrome (AVWS) may contribute to bleeding tendencies. Yet, comprehensive data with respect to platelet function and AVWS in LVAD patients in terms of bleeding events are scarce. METHODS Thirty-nine HeartMate II patients we...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
INTRODUCTION The aim of this study was to evaluate the medium-term clinical and angiographic results, as well as the occurrence and treatment of restenosis, following the implantation of sirolimus-eluting stents (SES) in patients undergoing coronary angioplasty. METHODS All patients who have an SES implanted in our department are entered into a database, with a view to evaluating the use of s...
OBJECTIVES The purpose of this study was to assess the frequency of very late stent thrombosis (VLST) after stenting with bare-metal stents (BMS) and drug-eluting stents (DES) for ST-segment elevation myocardial infarction (STEMI). BACKGROUND Stent thrombosis occurs more frequently after stenting for STEMI than after elective stenting, but there are little data regarding VLST. METHODS Conse...
Low-albedo asteroids preserve a record of the primordial solar system planetesimals and conditions in which nebula was active. However, origin evolution these are not well-constrained. Here we measured visible near-infrared (0.5 - 4.0 microns) spectra low-albedo mid-outer main belt. We show that numerous large (d > 100 km) dark (geometric albedo < 0.09) exterior to dwarf planet Ceres' orbit sha...
