Extracranial-Intracranial Vascular Shunt Procedures [PDF]

open access: yes, 1976
Cerebrovascular occlusive disease has been and continues to be a leading cause of death and disability throughout the world. In the United States there are about 400,000 new strokes each year. Some 90% of strokes are a result of vascular occlusion of the

Homocysteine in cerebrovascular disease: An independent risk factor for subcortical vascular encephalopathy [PDF]

open access: yes, 2001
Hyperhomocysteinemia is a risk factor for obstructive large-vessel disease. Here, we studied plasma concentrations of homocysteine and vitamins in patients suffering from subcortical vascular encephalopathy (SVE), a cerebral small-vessel disease leading ...

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

open access: yesAdvanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Assessing a 600-mg Loading Dose of Clopidogrel 24 Hours Prior to Pipeline Embolization Device Treatment [PDF]

open access: yes, 2018
Background: Clopidogrel/aspirin antiplatelet therapy routinely is administered 7-10 days before pipeline aneurysm treatment. Our study assessed the safety and efficacy of a 600-mg loading dose of clopidogrel 24 hours before Pipeline Embolization Device ...

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

open access: yesAdvanced Science, EarlyView.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

MRI Visualization of Whole Brain Macro- and Microvascular Remodeling in a Rat Model of Ischemic Stroke: A Pilot Study [PDF]

open access: yes, 2020
Using superparamagnetic iron oxide nanoparticles (SPION) as a single contrast agent, we investigated dual contrast cerebrovascular magnetic resonance imaging (MRI) for simultaneously monitoring macro- and microvasculature and their association with ...

ATF5‐Dependent GDF15 Expression Mediates Anesthesia‐Induced Neuroprotection Against Stroke

open access: yesAdvanced Science, EarlyView.
Anesthesia‐induced preconditioning protects against perioperative stroke. By manipulating ATF5 in excitatory neurons, it is shown that anesthesia‐driven ATF5 upregulation activates the mitochondrial unfolded protein response (UPRmt) and elevates GDF15 expression.
