Force‐Electric Nanotentacles of Tantalum Implant Accelerate Cellular Energy Metabolism/Crosstalk for Immunomodulation‐Vascularized Bone Integration

Advanced Science, EarlyView.
A biomimetic force‐electric nanotentacle‐enabled tantalum (Ta) implant with surface‐nanostructured LiTaO3 (n‐LiTaO3) was first developed via laser nanofabrication combined with Li+‐induced in situ reaction, enabling the transduction of ultrasound into bioelectrical cues.

How Does Left Ventricular Ejection Fraction Affect the Multimodal Assessment of Congestion in Patients with Acute Heart Failure? Results from a Prospective Study

Applied Sciences
The assessment of systemic congestion in acute heart failure (AHF) remains clinically challenging, particularly across different left ventricular ejection fraction (LVEF) phenotypes. This study aimed to evaluate whether differences exist in the degree of

D4F‐Functionalized Ceria Nanozyme‐CasRx Platform Suppresses STING and Reprograms the Renal Immune Niche in Acute Kidney Injury

Advanced Science, EarlyView.
D4F‐functionalized ceria nanozyme–CasRx nanoparticles preferentially target renal macrophages through SR‐B1‐mediated uptake in ischemia–reperfusion injury. Ceria scavenges excessive ROS, while CasRx silences STING signaling, shifting macrophages toward a less inflammatory, pro‐resolving state and increasing the proportion of regulatory T cells.

Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

Advanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,
