To explore the effect of mirror box therapy based on the mirror neuron (MN) system of the primary motor cortex (M1), we examined if direct (without a mirror) and indirect (with a mirror) observation of self-movement in healthy subjects induced changes in motor evoked potential (MEP) evoked by transcranial magnetic stimulation (TMS). MEPs were elicited from(More)
OBJECT The authors present a retrospective analysis of their experience in the treatment of vertebral artery (VA) dissecting aneurysms and propose a management strategy for such aneurysms, with special emphasis on the most formidable VA dissecting aneurysms, which involve the origin of the posterior inferior cerebellar artery (PICA). METHODS Since 1998,(More)
BACKGROUND Intracranial mycotic aneurysms, although rare neurovascular pathology, represented a neurosurgical challenge that required careful stepwise decision making. Different approaches for their management were used. We present our experience with 4 patients treated in terms of indications and efficacy of different treatment modalities. METHODS Four(More)
BACKGROUND Tentorial dural arteriovenous fistula (AVF) presented symptoms due to mass effect on the dilated draining vein. We report a patient presenting left hemisensory disturbance because of compression of the midbrain by a dilated draining vein of the AVF. The AVF has disappeared completely by drainer clipping after feeder embolization. CASE(More)
BACKGROUND Endovascular embolization of cerebral aneurysms has evolved rapidly worldwide within the last years, and has gained more popularity at the expense of surgical clipping; however, both regimens have inherent risks. This study was undertaken to asses the cerebral complications associated with both modalities of cerebral aneurysm treatment. METHODS(More)
OBJECTIVE The authors introduce a new fusion technique using 2 three-dimensional digital subtraction angiography images acquired by a flat-panel detector angiographic system to understand the detailed angioarchitecture of complex cerebral and spinal vascular malformations. METHODS Eleven consecutive cases of arteriovenous fistula or arteriovenous(More)
OBJECTIVE We sought to use a magnetic resonance (MR) plaque imaging technique to establish the plaque/muscle ratio (PMR) index panel to identify vulnerable plaques in subjects undergoing carotid artery stenting (CAS). METHODS Between 2008 and 2010 we treated 69 patients (71 lesions) by elective carotid endarterectomy (CEA) and 35 patients (36 lesions) by(More)
The mammalian translocon-associated protein (TRAP) complex comprises four transmembrane protein subunits in the endoplasmic reticulum. The complex associates with the Sec61 translocon, although its function in vivo remains unknown. Here, we show the involvement of the TRAP complex in endoplasmic reticulum-associated degradation (ERAD). All four subunits are(More)
OBJECT To elucidate an optimal managenent strategy for unruptured paraclinoid aneurysms, the authors retrospectively reviewed their experience in the treatment of 100 patients who underwent 112 procedures for111 paraclinoid aneurysms performed using direct surgery and/or endovascular treatment. METHODS Between 1997 and 2002, 111 unruptured paraclinoid(More)
BACKGROUND The balance between degradation and synthesis of extracellular matrix determines its content in atherosclerotic tissue. To examine the role of expression balance of matrix metalloproteinases (MMPs) to their inhibitors, tissue inhibitors of metalloproteinases (TIMPs) and tissue factor pathway inhibitor-2 (TFPI-2) in the development and disruption(More)
