Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Nanocrystal Compressive Residual Stresses: A Strategy to Strengthen the Bony Spines of Osteocytic and Anosteocytic Fish

Advanced Science, EarlyView.
Advanced neoteleost fishbones, such as medaka, challenge bone adaptation strategies. While zebrafish bones contain osteocyte‐mediated porosity, medaka bones lack it, raising questions about alternative reinforcement mechanisms. Using advanced imaging, this study reveals higher residual compressive strains in medaka bone, suggesting an adaptation that ...
