4D ultrasound reveals regional left atrial strain remodelling in a murine model of reversible pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend Traditional planar imaging approaches of the left atrium do not capture complex geometry. Four‐dimensional imaging allows the acquisition of 3D data + time to visualize left atrial geometry and kinematics. We designed an advanced analysis technique to investigate left atrial biomechanics in a model of pressure overload and ...

P2X7 receptors promote atrial remodeling and atrial fibrillation susceptibility via reactive oxygen species‐mediated mitogen‐activated protein kinase signaling activation

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
Abstract Atrial fibrillation (AF), the most common clinical arrhythmia, is driven by inflammatory activation and oxidative stress, though precise molecular links remain unclear. This study identifies the P2X7 receptor as a key upstream regulator orchestrating proarrhythmic atrial remodeling through reactive oxygen species (ROS)‐mediated mitogen ...

Supercritical‐flow structures in a Cretaceous submarine channel–lobe transition zone, Point Loma Formation, California

The Depositional Record, Volume 12, Issue 3, June 2026.
We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...
