Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Access via the internal jugular vein [PDF]

open access: yes, 2008
Central venous access via the internal jugular vein (IJV) is safe, relatively easy and very commonly used in infants and children undergoing cardiac surgery for congenital heart disease. Because of the wide range of anatomical variations an ultrasound-

3D‐Printed Multidimensional Bionic Mg‐MC/PLGA Composite for Tailored Repair of Segmental Long Bone Defects

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops 3D‐printed Mg‐MC/PLGA scaffolds with varying Mg concentrations (0–20%). The 5% Mg scaffold shows optimal cytocompatibility, osteogenic activity in vitro, and significantly enhances bone regeneration in rabbits, improving bone volume and mechanical strength.

Suppressing t(4;11) Acute Leukemia by Lipopolymer Nanoparticle Delivery of siRNA Targeting KMT2A::AFF1 with Enhanced Extrahepatic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a new lipopolymer nanoparticle (LPNP) system that efficiently delivers siRNA to leukemia cells. The LPNPs silence the leukemia fusion gene KMT2A::AFF1, induce apoptosis, and decrease leukemia burden in mice. These results demonstrate the potential of LPNPs as a targeted siRNA therapy for acute lymphoblastic leukemia.

Microscopically Adaptable Bioink Guide Cell Compartmentalization toward Morphogenesis of a Functional Vasculature‐Like System

open access: yesAdvanced Healthcare Materials, EarlyView.
Contractile vasculatures are fabricated through a one‐step bioprinting strategy. The adaptable microenvironment provided by ECM‐mimicking bioink triggers cell sorting and compartmentalization of endothelial cells and vascular smooth muscle cells toward a histological configuration by focal adhesion kinase‐mediated upregulation of cell adhesion and ...
