Development of Antimicrobial AgNPs‐Coated Polydioxanone Sutures Using Low‐Pressure Plasma: Physicochemical Characterization and In Vitro Evaluation

Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
AgNPs‐coated PDO sutures were developed by low‐pressure plasma treatment, achieving homogeneous nanoparticle deposition without any significant changes in the polymer's physicochemical properties. The sutures exhibited controlled silver release, activity against S. aureus and E.

Tissue‐Resident Macrophage in Inflammation and Cancer

MedComm, Volume 7, Issue 9, September 2026.
Opposing macrophage functions in inflammation and cancer converge on shared mechanistic nodes, informing cross‐disease therapeutic strategies. ABSTRACT Tissue‐resident macrophages (TRMs) are long‐lived immune cells strategically distributed across organs, where their functional plasticity enables both homeostatic maintenance and pathological ...

Transmembrane Protein PTCHD4 Is a Novel Regulator of Cellular Senescence and Age‐Related Pathologies

Aging Cell, Volume 25, Issue 9, September 2026.
PTCHD4 is induced by aging‐ and injury‐associated stresses and acts as a senescence‐associated transmembrane regulator. Through AKT activation, PTCHD4 promotes cellular senescence, SASP, functional decline, and pulmonary fibrosis, whereas PTCHD4 deficiency dampens AKT signaling and alleviates senescence‐associated pathological phenotypes.

AMPK‐mediated prevention of vascular dysfunction with metformin: Experimental and population‐based evidence

British Journal of Pharmacology, Volume 183, Issue 17, Page 5389-5406, September 2026.
Angiotensin II induces vascular inflammation, senescence, extracellular matrix (ECM) degradation and endothelial dysfunction, thus impairing SK+/IK+ channel function and reducing endothelial‐dependent hyperpolarisation (EDH). Metformin activates AMPK, increasing SK+/IK+ channel function and restoring vasorelaxation.
