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 ...

Epileptiform Activity and Seizure Risk Follow Long‐Term Non‐Linear Attractor Dynamics

Advanced Science, EarlyView.
This study leverages the HAVOK framework to model long‐term, nonlinear attractor dynamics underlying epileptiform activity and seizure risk in epilepsy patients. By identifying key forcing mechanisms driving chaotic transitions, the findings improve seizure risk forecasting over multi‐day cycles and provide a pathway for personalized, data‐driven ...
