Laser-driven high-power X- and gamma-ray ultra-short pulse source

, 2008
A novel ultra-bright high-intensity source of X-ray and gamma radiation is suggested. It is based on the double Doppler effect, where a relativistic flying mirror reflects a counter-propagating electromagnetic radiation causing its frequency ...

An Aptamer‐Based EXACT Anticoagulant as a Sustainable, Animal‐Free Alternative to Unfractionated Heparin

Advanced Science, EarlyView.
By simply conjugating thrombin's active‐site inhibitor, dabigatran, with an exosite inhibitor, aptamer HD1, the resulting EXosite‐ACTive site (EXACT) inhibitors show two orders of magnitude higher potency and selectivity via synergistic binding, while maintaining the aptamer's antidote‐reversible trait, yielding a potential substitute for the animal ...

Inhibition of Macrophage ARID3A Alleviates Myocardial Ischemia‐Reperfusion Injury After Heart Transplantation by Reducing THBS1/CD47 Signaling‐Mediated Neutrophil Extracellular Traps Formation

Advanced Science, EarlyView.
This study reveals that ARID3A in macrophages can transcriptionally regulate the THBS1‐CD47 axis after heart transplantation (HT), thereby inducing activated neutrophils to release NETs through the p38 MAPK signaling pathway. The itaconate derivative 4‐OI can inhibit ARID3A in macrophages and promote the accumulation of antioxidant factors, thereby ...

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

Engineered Multifunctional Hydrogel Delivering Novel CBX7 Inhibitor Modulates Cuproptosis Via Liquid–Liquid Phase Separation to Restore Cardiac Function in Aged Myocardial Infarction

Advanced Science, EarlyView.
An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...
