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)
Human islet amyloid polypeptide (hIAPP) is the major component of amyloid deposits in islets of type 2 diabetic patients. hIAPP misfolding and aggregation is one of the factors that may lead to β-cell dysfunction and death. Endogenous chaperones are described to be important for the folding and functioning of proteins. Here, we examine the effect of the… (More)
UNLABELLED Flow diverters represent a useful tool in the treatment of fusiform aneurysms and wide-neck saccular aneurysms which until the advent of this technology were problematic to treat. Pipeline™ Embolization Device (PED) has been described in several series showing high rates of occlusion and being relatively safe. OBJECTIVE Shows the experience in… (More)
The "pontine warning syndrome" is characterized by recurrent episodes of motor hemiparesis, dysarthria and horizontal gaze palsy associated with basilar artery branch infarction. We report a case of a patient who presented with recurrent, self-limited episodes of locked-in syndrome, related to a bilateral pontine infarction. As far as we know, this clinical… (More)
BACKGROUND The mechanical thrombectomy (MT) for endovascular clot retrieval has dramatically improved successful revascularization and clinical outcome in selected acute stroke patients. MT is typically performed via a transfemoral approach, but catheterization of the occluded vessel can be problematic in cases of extensive vessel tortuosity. We describe a… (More)
BACKGROUND AND OBJECTIVE Intraoperative monitoring (IOM) has been used in different surgical disciplines since the 1980s. Nonetheless, regular routine use of IOM in interventional neuroradiology units has only been reported in a few centers. The aim of this study is to report our experience, 1 year after deciding to implement standardized IOM during… (More)
Arterial revascularization is the most effective therapy for acute stroke patients. Systemic thrombolysis with recombinant tissue plasminogen activator based on baseline non-contrast CT (NCCT) imaging criteria is the only treatment approved to date, which is limited by severe timing and medical restrictions, and a narrow efficacy. The simple imaging… (More)
