Novel Drug‐Testing Platform for Vascular Injury‐induced Intimal Hyperplasia Using a Microphysiological System

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a 3D vascular injury model using a microphysiological system that mimics key features of intimal hyperplasia. Antiproliferative drugs reduced VSMC proliferation but worsened endothelialdenudation. A combination of diphenyleneiodonium and quercetin effectively reduced proliferation and migration of VSMC and inflammation while ...

Morphological and Compositional Features of Chronic Internal Carotid Artery Occlusion in MR Vessel Wall Imaging Predict Successful Endovascular Recanalization

open access: yesDiagnostics, 2023
Background: We sought to determine if the morphological and compositional features of chronic internal carotid artery occlusion (CICAO), as assessed by MR vessel wall imaging (MR-VWI), initially predict successful endovascular recanalization.

Immunomodulation With Local, Sustained Delivery of Pituitary Adenylate Cyclase Activating Polypeptide Results in Improved Functional Recovery in Stroke‐Injured Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
The tissue and functional benefits are demonstrated with local, sustained delivery of an anti‐inflammatory peptide, pituitary adenylate cyclase‐activating polypeptide (PACAP), for stroke treatment in a mouse model. Prolonged PACAP treatment modulated astrocyte and microglia toward pro‐reparative phenotypes, enhanced neuroprotection and preservation of ...

Uniting 4D Printing and Melt Electrowriting for the Enhancement of Regenerative Small Diameter Vascular Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
A hybrid 4D printing strategy enables the fabrication of shape‐morphing, mechanically reinforced tubular constructs for vascular tissue engineering. By combining alginate‐methylcellulose hydrogels with melt electrowritten polycaprolactone fibers and protein‐based functionalization, this platform supports spatially organized co‐cultures of fibroblasts ...

Treatment strategy of endovascular recanalization for chronic ischemic stroke with large vessel occlusion

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2020
The diagnosis and treatment of chronic large vessel occlusion is in its infancy period. At present, few studies reported some successful cases, but on the whole, the opening of large vessel occlusion is in a state of exploration in terms of preoperative ...

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

open access: yesAdvanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Succinate Dehydrogenase Subunit A (SDHA) Mediated Microglia Extracellular Traps Formation Participating in Cerebral Ischemic Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
This study investigates the mechanism of succinate dehydrogenase (SDH)‐mediated succinate oxidation in microglia extracellular traps (MiETs) formation and neuronal injury after cerebra I/R injury. Dimethyl malonate (DMM), a competitive SDH inhibitor, could reduce MiETosis by inhibiting succinate oxidation and mtROS production during reperfusion ...

A angiografia no diagnóstico da patologia vascular cerebral. Indicações actuais e controvérsias.

open access: yesActa Médica Portuguesa, 1993
The role of cerebral angiography in the diagnosis of cerebrovascular disease is currently being questioned due to both the increasing availability of carotid sonography and the recent introduction of Magnetic Resonance Angiography (MRA).
