Direct Gravity‐Induced Modulation of Cardiac Conduction Pathways Evidenced Through Propagation Features in Electrophysiological Mapping

Advanced Materials Technologies, EarlyView.
A high‐density wearable body‐surface potential mapping array reveals how gravity reshapes cardiac conduction in real time. By resolving spatiotemporal delay patterns invisible to conventional ECG, the platform uncovers posture‐dependent electrophysiological adaptations across the thorax.

ELABELA Targets Mitochondria to Modulate Heart Development

Advanced Science, EarlyView.
The role of peptide ELABELA (ELA) in cardiomyocyte apoptosis and congenital heart disease (CHD) is unclear. ELA deficiency caused cardiomyocyte apoptosis and CHD. A novel ELA‐APJ‐AKT‐BCL2/BAX axis in regulating mitochondrial function and contributing to CHD pathogenesis was established.

Bufalin Inhibits the PI3K/AKT Pathway by Targeting GTF3C4 to Impede Breast Cancer Progression

Advanced Science, EarlyView.
Mechanisms of Bufalin‐Mediated Intervention in Breast Cancer. ABSTRACT Breast cancer incidence is rising globally, presenting challenges such as treatment side effects and drug resistance. Bufalin is a bufadienolides compound with potential anti‐cancer effects. This study shows that bufalin inhibits malignant proliferation of MDA‐MB‐231 and MCF‐7 cells

Postoperative Stress Accelerates Atherosclerosis Through Inflammatory Remodeling of the HDL Proteome and Impaired Reverse Cholesterol Transport

Advanced Science, EarlyView.
The study shows that noncardiac surgical inflammation rapidly disrupts HDL function and cholesterol efflux in mice and human patients. Impaired reverse cholesterol transport after surgery drives rapid lipid accumulation, NETosis, and apoptosis within atherosclerotic plaques.
