FOXM1 Protects Against Myocardial Ischemia‐Reperfusion Injury in Rodent and Porcine Models by Suppressing MKRN1‐Dependent LKB1 Ubiquitination

Advanced Science, EarlyView.
FOXM1 maintains mitochondrial bioenergetic function by inhibiting MKRN1‐mediated ubiquitination of LKB1 in cardiomyocytes. Loss of FOXM1 in cardiomyocytes results in upregulation of MKRN1, which enhances LKB1 ubiquitination and disrupts AMPK signaling and energy metabolism pathways. Conversely, FOXM1 overexpression preserves mitochondrial bioenergetics

Depth‐Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain

Advanced Electronic Materials, EarlyView.
In this study, a depth‐adjustable, flexible 3D multi‐shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re‐fabrication.

Knowledge, Attitude, and Practice on Atrial Fibrillation and Atrial Fibrillation Screening in High‐Risk Population: A Cross‐Sectional Study

AGING MEDICINE, EarlyView.
Distribution of KAP scores for participants ≤ 65 versus > 65 years. ABSTRACT Objectives Atrial fibrillation (AF) is a common clinical arrhythmia. Failure to identify AF leaves patients at a considerably higher risk of disability and death, making its early screening and prevention extremely important. This study aimed to investigate knowledge, attitude,

E‐CAD: Electroactive Polymer‐Based Cardiac Assist Device with Low Power Consumption

Advanced Intelligent Systems, EarlyView.
Conventional cardiac assist devices often require high power, involve direct blood contact, and risk driveline infections. This work presents a soft electroactive polymer‐based system that compresses the heart externally while consuming <0.3 W. With no blood contact, a 0.3 mm driveline, and a compact design, E‐CAD demonstrates enhanced output and ...
