Ultrasound‐Activated Nanoinhibitors Blocking the Chemo‐Immune Checkpoint to Overcome Chemotherapy‐Induced Immune Resistance

Advanced Science, EarlyView.
A sono‐responsive chemo‐immune checkpoint nanoinhibitor (Sono‐TT8) co‐delivering TPZ chemotherapy and siXkr8 simultaneously kills tumor cells and blocks PS externalization, reversing chemotherapy‐induced immunosuppression and enhancing antitumor immunity. ABSTRACT Breast cancer features an immunosuppressive tumor microenvironment following chemotherapy

Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

Advanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

Advanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

Discovery of 1RXS J171824.2-402934 as an X-ray burster

, 2000
We report the first-time detection of a type-I X-ray burst from a position that is consistent with that of 1RXS J171824.2-402934. The detection was made on Sep 23, 1996, with the Wide Field Cameras on board the BeppoSAX satellite. The burst had a peak intensity of 1.3 Crab units in 2 to 28 keV and is relatively long (at least 3.5 min).
