P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

open access: yesAdvanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

UGDH Lactylation Aggravates Osteoarthritis by Suppressing Glycosaminoglycan Synthesis and Orchestrating Nucleocytoplasmic Transport to Activate MAPK Signaling

open access: yesAdvanced Science, EarlyView.
Lactylation of UDP‐glucose dehydrogenase (UGDH) represses its enzymatic activity and causes glycosaminoglycans loss. In addition, UGDH lactylation facilitates its interaction with chromosome region maintenance 1 (CRM1) and promotes the nucleocytoplasmic transport.

LIPUS Promotes Calcium Oscillation and Enhances Calcium Dependent Autophagy of Chondrocytes to Alleviate Osteoarthritis

open access: yesAdvanced Science, EarlyView.
A non‐invasive and safe physical therapy, low‐intensity pulsed ultrasound (LIPUS) can alleviate osteoarthritis. This study dynamically “visualizes” the invisible mechanical stimuli of LIPUS on living chondrocytes by fluorescence imaging technology in the form of calcium oscillations, confirming LIPUS maintains cartilage homeostasis by promoting ...

Topology‐Optimized Bound States in the Continuum with High‐Q Acoustic Field Enhancement

open access: yesAdvanced Science, EarlyView.
This study presents a topology optimization method for acoustic metamaterials, achieving high‐Q resonances by redesigning a single unit cell within a periodic array. The design enables precise pressure confinement and energy trapping, validated through experiments.
