Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Safety of thrombolysis in acute ischemic stroke patients with previous aortic abdominal aneurysm repair

Journal of Stroke and Cerebrovascular Diseases
Objective: Intravenous thrombolysis is the standard treatment for acute ischemic stroke (AIS), but its safety in patients with a history of abdominal aortic aneurysm (AAA) repair remains unclear.

Risk factors are different for deep and lobar remote hemorrhages after intravenous thrombolysis.

PLoS ONE, 2017
Background and purposeRemote parenchymal haemorrhage (rPH) after intravenous thrombolysis is defined as hemorrhages that appear in brain regions without visible ischemic damage, remote from the area of ischemia causing the initial stroke symptom.

Engineered Brain‐Targeted Exosomes Delivering FGF1 for Sustained Glycemic Regulation and Multitarget Neurovascular Protection in Diabetic Stroke

Advanced Science, EarlyView.
ABSTRACT Diabetic stroke is characterized by a hyperglycemic and pro‐inflammatory microenvironment that exacerbates neurovascular dysfunction. However, the blood–brain barrier (BBB) remains a formidable obstacle, restricting the delivery of most therapeutic molecules.

Intravenous Thrombolysis in Patients on Direct Oral Anticoagulants: Analysis of the Get With The Guidelines Stroke Registry

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Intravenous thrombolysis for acute ischemic stroke (AIS) is a proven effective treatment. Whether thrombolysis in patients with AIS with recent direct oral anticoagulant (DOAC) use is safe and efficacious is not well established.

Thrombolysis for acute ischemic stroke in the setting of a recently created brachiocephalic arteriovenous fistula [PDF]

Romanian Journal of Neurology
Introduction. Intravenous thrombolysis can be performed in the setting of acute ischemic stroke when eligibility criteria are met. We present our experience with intravenous thrombolysis in a patient who had undergone arteriovenous fistula creation for ...

SR‐A3 Promotes USP18‐Mediated deISGylation of STING to Protect Against Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
MI/RI is a major clinical challenge with high morbidity and mortality. This study demonstrates that SR‐A3 expression is downregulated in MI/RI, and its deletion exacerbates damage via the USP18/ISG15/STING axis, revealing SR‐A3 as a potential therapeutic target.

Nano Proton Scavengers Modulate Endosomal pH to Inhibit Microglial Activation and Enhance Stroke Recovery

Advanced Science, EarlyView.
Amphiphilic sulfonated chitosan nanoparticles buffer endo/lysosomal acidity in microglia by limiting V‐ATPase membrane recruitment and restoring endosomal homeostasis. Following systemic administration, they accumulate in the ischemic hemisphere partly through association with infiltrating immune cells, suppress TLR3/IRF3 and TLR4/NF‐κB signaling ...
