BACKGROUND We aimed to assess the safety and efficacy of thrombectomy for the treatment of stroke in a trial embedded within a population-based stroke reperfusion registry. METHODS During a 2-year period at four centers in Catalonia, Spain, we randomly assigned 206 patients who could be treated within 8 hours after the onset of symptoms of acute ischemic(More)
BACKGROUND AND PURPOSE To describe the safety and effectiveness of a self-expanding and fully retrievable stent (Solitaire AB; ev3 Inc, Plymouth, MN) in revascularization of patients with acute ischemic stroke. METHODS Prospective, single-center study of 20 patients with an acute ischemic stroke attributable to a large artery occlusion of the anterior(More)
Heterozygous coding mutations in the INS gene that encodes preproinsulin were recently shown to be an important cause of permanent neonatal diabetes. These dominantly acting mutations prevent normal folding of proinsulin, which leads to beta-cell death through endoplasmic reticulum stress and apoptosis. We now report 10 different recessive INS mutations in(More)
Mitofusin 2 (MFN2) plays critical roles in both mitochondrial fusion and the establishment of mitochondria-endoplasmic reticulum (ER) interactions. Hypothalamic ER stress has emerged as a causative factor for the development of leptin resistance, but the underlying mechanisms are largely unknown. Here, we show that mitochondria-ER contacts in anorexigenic(More)
BACKGROUND AND PURPOSE Mechanical thrombectomy using stent retriever devices have been advocated to increase revascularization in intracranial vessel occlusion. We present the results of a large prospective study on the use of the Solitaire Flow Restoration in patients with acute ischemic stroke. METHODS Solitaire Flow Restoration Thrombectomy for Acute(More)
MicroRNAs (miRNAs) have recently emerged as key regulators of metabolism. However, their potential role in the central regulation of whole-body energy homeostasis is still unknown. In this study we show that the expression of Dicer, an essential endoribonuclease for miRNA maturation, is modulated by nutrient availability and excess in the hypothalamus.(More)
SUMMARY The Merci Retrieval System (TM) (Concentric Medical, Mountain View, CA, USA) was approved in 2004 for restoring blood flow in patients experiencing an acute stroke who are otherwise ineligible for intravenous tPA, or in whom intravenous tPA treatment has failed. However, this treatment results in successful recanalization in less than 60% of(More)
IMPORTANCE Endovascular thrombectomy with second-generation devices is beneficial for patients with ischemic stroke due to intracranial large-vessel occlusions. Delineation of the association of treatment time with outcomes would help to guide implementation. OBJECTIVE To characterize the period in which endovascular thrombectomy is associated with(More)
SUMMARY This study aimed to report the results obtained in treating small ruptured and unruptured intracranial aneurysms using Cerecyte coils. A prospective, non-randomized multicenter registry operating in Spain with a reporting period between May 2005 and September 2007.We present clinical and angiographic results for 48 small aneurysms (26 ruptured, five(More)
Sixty eight cases of chronic subdural hematoma (CSDH) surgically treated (December 1984-December 1988) with twist drill craniostomy (3-4 mm) and application of a closed drainage system (CDS) are reviewed. The patients were distributed in four groups depending on the density of the hematoma: hypodense (36 cases), isodense (6 cases), of mixed density (22(More)
