Endothelin-1 (ET-1) increases pulmonary vascular tone through effects on pulmonary artery smooth muscle cells (PASMC) via membrane bound ET-1 receptors. Circulating ET-1 causes vascular remodeling by promoting SMC proliferation, migration, and inhibiting SMC apoptosis. While endothelial cells (EC) are the primary source of ET-1, whether ET-1 produced by SMC modulates ...

The relative importance of ATP as a functional sympathetic neurotransmitter in blood vessels has been shown to be increased when the level of preexisting vascular tone or pressure is increased, in studies carried out in rat mesenteric arteries. The aim of the present study was to determine whether tone influences ...

Renal denervation is a new interventional approach to treat hypertension with variable results. The purpose of this study was to correlate response to endovascular radiofrequency ablation of renal arteries with nerve and ganglia distributions. We examined how renal neural network anatomy affected treatment efficacy. A multielectrode radiofrequency catheter (15 W/60 ...

It has been almost twenty years since the discovery that pulmonary vein ectopy is largely responsible for initiation of paroxysmal atrial fibrillation (PAF). We have spent the better part of those twenty years seeking effective ways of eliminating pulmonary vein ectopy or its effect on the atrial rhythm. This article ...

The long-term coronary arterial response of biodegradable polymer biolimus-eluting stents (BES) remains unclear. We sought to evaluate the coronary arterial response of biodegradable polymer BES at 5 years after stent implantation using optical coherence tomography (OCT) as compared with that of durable polymer sirolimus-eluting stents (SES) and bare-metal stents (BMS). ...

Intracranial aneurysms with a fusiform morphology are rarely amenable to direct clipping and instead require occlusion techniques that involve revascularization. One such technique is aneurysm trapping and excision with end-to-end reanastomosis of the inflow and outflow arteries. MCA and PICA aneurysms often have redundant parent artery that allows primary reanastomosis. ...

We present an unusual complication following endovascular repair of traumatic thoracic aortic injury using a homemade stent-graft. Although an initial technical success was apparently obtained, the aorta showed remarkable dilatation without shortening or migration of the stent skeleton in late follow-up period. The possible cause of the dilatation was considered ...

We report the evaluation of dual-gelling poly(N-isopropylacrylamide)-based polymer systems as embolic agents for intracranial aneurysms. These hydrogels undergo gelation physically via temperature-responsiveness of poly(NIPAAm) and chemically through a Michael-addition reaction between thiol and vinyl functional groups on the copolymers. Cytotoxicity studies were performed for biocompatibility of the hydrogels. In vitro ...

Cyclooxygenase-2 (COX-2) and Microsomal Prostaglandin E2 Synthase-1 (mPGES-1) catalyze isomerization of the cyclooxygenase product PGH2 into PGE2. Deletion of COX-2/mPGES-1 suppresses carotid artery atherogenesis and angiotensin II-induced aortic aneurysms formation, and attenuates neointimal hyperplasia after vascular injury in mice. The upregulation of COX-2/mPGES-1 in the wall of ruptured human cerebral ...

Copeptin is a peptide derived from pre-provasospression along with arginine vasospressin. In the setting of aneurysmal subarachnoid hemorrhage (SAH), elevated serum copeptin levels correlate with vasospasm, inpatient mortality, mortality at 1 year, and poor functional outcome at 1 year. The potential role of serum copeptin levels in the management of ...

The recent American College of Cardiology/American Heart Association guideline recommended carotid artery stenting (CAS) as an alternative to carotid endarterectomy (CEA) for symptomatic patients. This and the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) form the basis for seeking more liberalized indications and reimbursement for CAS. For the years 2005-2007, ...
