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 ...

A Novel Protein NAB1‐356 Encoded by circRNA circNAB1 Mitigates Atrial Fibrillation by Reducing Inflammation and Fibrosis

Advanced Science, EarlyView.
The circRNA circNAB1 is downregulated in AF patient. Silencing circNAB1 promotes collagen deposition and inflammation, whereas overexpression reduces AF susceptibility. circNAB1 encodes the protein NAB1 356 that interacts with EGR1 to mitigate fibrosis and inflammation.
