Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

Advanced 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.

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

Advanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...

Aligned Conductive Magnetic Nanofibers with Directional Magnetic Field Stimulation Promotes Peripheral Nerve Regeneration

Advanced Science, EarlyView.
Peripheral nerve injury necessitates alternatives to autografts. This study combines magnetic nanoparticles, oriented PCL fibers, and Ppy to create a conductive, magnetically active scaffold. In vitro and in vivo experiments demonstrated enhanced downstream pathways of calcium signaling, as revealed by transcriptome analysis.

CAMP: Closed‐Loop Acoustic‐Magnetic Propulsion of Microrobots for Precision Cell Manipulation

Advanced Intelligent Systems, EarlyView.
This work demonstrates, for the first time, closed‐loop control of acoustically driven, magnetically steerable microrobots with automated speed modulation. Closed‐loop navigation allows guided motion and speed control, allowing highly accurate trajectory following. pen‐loop control enables mammalian cell manipulation via microrobots, highlighting their

Radiotherapy or surgical treatment of early glottic carcinoma: A population-based study from the Swedish Head and Neck Cancer Register evaluating primary treatment outcomes for patients with T1a/T1b tumors. [PDF]

Cancer
Abstract Background Radiotherapy (RT) has been the treatment of choice for T1 glottic squamous cell carcinomas with curative intent; however, transoral microsurgery (MLS) has gradually taken its place. The objective of this study was to compare the outcomes of the two treatment modalities.
