Dramatic Enhancement and Integration of Properties in Pork Belly‐Inspired All‐Biomass Composite Films via Facile, Sustainable, and Controllable Design

Advanced Science, EarlyView.
A pork belly‐inspired all‐biomass composite film was constructed through layer‐by‐layer assembly of cellulose nanofibers (CNFs), gelatin, and graphitized carbon nanosheets (GCNs) via hydrogen bonding and π–π stacking interactions. The excellent mechanical properties, effective thermal management, and outstanding EMI shielding performance of the ...

RUNX1‐Mediated Hypoxic Signaling Impairs Myogenesis and Promotes Fibrosis in Myopathies

Advanced Science, EarlyView.
Myofiber overgrowth was associated with reduced blood flow and a potential hypoxic state in broiler breast muscle, accompanied by increased RUNX1 expression. Elevated RUNX1 impaired myogenic regeneration, promoted fibrosis, and disrupted the signaling niche required for efficient muscle repair, contributing to pathological degeneration in Wooden Breast
