Prospective evaluation of acute cerebral injury by DW-MRI following transcarotid artery revascularization using a double-layer micromesh stent.

Background: Transcervical carotid artery revascularization (TCAR) has demonstrated a low overall stroke rate in carotid artery stenting (CAS). Furthermore, the use of a double-layer micromesh stent is expected to reduce embolization and plaque prolapse. The combination of TCAR and the double layer stent may lead to improved results compared to previously reported outcomes.

Cost-effectiveness of Carotid Surgery.

Background: The purpose of this study is to determinate the cost-effectiveness of carotid endarterectomy (CEA) versus transfemoral stenting (TFS) and transcervical stenting (TCS) in a short- and long-term basis in symptomatic and asymptomatic patients.

Methods: From January 2003 to December 2014, patients from the vascular department, with symptomatic or asymptomatic carotid stenosis, who were clinically and anatomically suitable for TFS, TCS, or CEA, were included. Prospective cost data for each individual procedure and complication during follow-up were obtained from the diagnosis-related group.

Stretchable conductive polypyrrole films modified with dopaminated hyaluronic acid.

In this paper, we report the modification of polypirrole (PPy) with dopaminated hyaluronic acid (HADA). This design improves PPy adhesion onto stretchable materials such as poly(dimethylsiloxane) (PDMS) allowing the formation of conducting films on this kind of very flexible, hydrophobic materials. The results revealed that described PPy modification allows to obtain stable PPy:HADA nano-suspension able to cast films directly on PDMS.

Retromer- and WASH-dependent sorting of nutrient transporters requires a multivalent interaction network with ANKRD50.

Retromer and the associated actin-polymerizing WASH complex are essential for the endocytic recycling of a wide range of integral membrane proteins. A hereditary Parkinson's-disease-causing point mutation (D620N) in the retromer subunit VPS35 perturbs retromer's association with the WASH complex and also with the uncharacterized protein ankyrin-repeat-domain-containing protein 50 (ANKRD50). Here, we firmly establish ANKRD50 as a new and essential component of the SNX27-retromer-WASH super complex.

A diffusion-weighted magnetic resonance imaging-based study of transcervical carotid stenting with flow reversal versus transfemoral filter protection.

Background: Transfemoral carotid artery stenting (CAS) has been associated with a high incidence of embolic phenomena and silent brain infarction. The goal of this study was to compare the incidence of new ischemic cerebral lesions on diffusion-perfusion magnetic resonance imaging (MRI) sequences after transcervical CAS performed with carotid flow reversal vs stenting via transfemoral approach with distal filter protection.

Methods: During a 26-month period, 64 consecutive patients diagnosed with significant carotid stenosis by ultrasound imaging were assigned to transcervical CAS with carotid flow reversal or a transfemoral approach with a distal filter.
