Shear Stress Targeted Delivery of Nitroglycerin to Brain Collaterals Improves Ischaemic Stroke Outcome

Advanced Science, EarlyView.
Shear‐activated nanoparticles carrying nitroglycerin selectively target high‐shear stress collateral vessels during ischaemic stroke, enhancing blood flow to at‐risk brain without systemic side effects. This novel approach significantly improves outcomes in animal models, outperforming conventional nitroglycerin delivery.

FMO2 Promotes Angiogenesis via Regulation of N‐Acetylornithine

Advanced Science, EarlyView.
This study identifies flavin‐containing monooxygenase 2 (FMO2) as a novel proangiogenic regulator in endothelial cells. Targeted FMO2 ablation impairs vessel sprouting, whereas its compensation potently enhances angiogenesis. Metabolomics and single‐cell sequencing reveal that FMO2 drives vascular growth via the N‐acetylornithine/ATF3/NOTCH1 axis ...

A Single‐Component Adhesive Sponge Based on Blood‐Triggered and Autopenetrative Adhesion for Robust Vascular Closure

Advanced Science, EarlyView.
This study presents MonoSeal, a single‐component adhesive sponge powered by the novel Autopenetrative Adhesion (APA) mechanism. Unlike traditional adhesives, which require external stimuli, APA enables strong tissue adhesion under dynamic, high‐pressure bleeding conditions. MonoSeal's ability to autonomously seal large‐size arterial defects underscores

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis

, 2017
In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during invasive coronary angiography (ICA), is most often used in clinical ...

ACE‐mediated Glycosylation Stabilizes PSAP To Promote GPR37‐dependent Macrophage‐Nucleus Pulposus Cells Crosstalk and TGFβ Signaling in Alleviating Intervertebral Disc Degeneration

Advanced Science, EarlyView.
ACE can modulate the CBL‐mediated K48 ubiquitination degradation of PSAP by altering its glycosylation levels in NP cells. As a result, NP cells secrete PSAP, which interacts with GPR37 on macrophage surfaces, facilitating their polarization toward the M2 phenotype. These M2 macrophages subsequently secrete TGFβ, which exerts feedback effects on the NP

Effect of guidewire on contribution of loss due to momentum change and viscous loss to the translesional pressure drop across coronary artery stenosis: An analytical approach

BioMedical Engineering OnLine, 2011
Background Guidewire (GW) size and stenosis dimensions are the two major factors affecting the translesional pressure drop. Studying the combined effect of these parameters on the mean pressure drop (Δp) across the stenosis is of high practical ...

Ultrafine Molybdenum Wire Braided Neurointerventional Implants: Bridging Biodegradability and Neurovascular Safety for Stroke Treatment

Advanced Science, EarlyView.
Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...
