The Interplay Between Molybdopterin Synthase and Metal Metabolism Contributes to Pathogenicity in Acinetobacter baumannii

Advanced Science, EarlyView.
Pathogenic Acinetobacter baumannii scavenges metal ions as nutritional elements to survive within the host. This study demonstrates that molybdopterin synthase is essential for pathogenesis and full virulence during infection. Molybdopterin synthase subunit MoaE constitutes an intrinsically disordered C‐terminal histidine rich tail, which mediates ...

A UBE3A‐UTX Proteostasis‐Epigenetic Axis Governs Hypothalamic Energy Homeostasis

Advanced Science, EarlyView.
Ubiquitin protein ligase E3A (UBE3A) regulates hypothalamic energy homeostasis and promotes degradation of the histone demethylase UTX (KDM6A). Neuronal UBE3A loss increases susceptibility to diet‐induced obesity and is accompanied by UTX accumulation, reduced histone H3 lysine 27 trimethylation, and altered endoplasmic reticulum stress‐responsive gene

Development‐Informed Microsphere Assemblies Enable Spatiotemporally Programmed Bone–Vascular Organoid‐Like Constructs for Large Bone Defect Repair

Advanced Science, EarlyView.
Single‐cell‐guided prioritization of BMP4 and VEGFA is combined with temporally programmed BMSCs and a Matrigel‐free GelMA/PEO/bioactive‐glass assembled‐microsphere matrix to generate bone–vascular organoid‐like constructs. The platform coordinates osteogenic differentiation, endothelial activation, vascular‐like microchannel formation, and ...

Analysis of Shaft Voltage in a Doubly-fed Induction Generator

, 2009
Fast switching transients and common mode voltage generated by pulse width modulated voltage in high frequency applications may cause many unwanted problems such as shaft voltage and resultant bearing currents. The main objective of this research work is

A Citrulline‐Functionalized Patch Coordinates Macrophage NRF2 Signaling and Arginine Metabolism for Tendon‐to‐Bone Repair

Advanced Science, EarlyView.
A locally implanted patch combines citrulline‐functionalized carbon dots, a thioketal‐containing membrane coating from tendon‐derived stem cells, and aligned core–shell fibers. In macrophages, the patch reduces inflammatory markers and enhances antioxidant signaling through nuclear factor erythroid 2‐related factor 2 (NRF2); in rats and rabbits, it ...

Hierarchical Organization of Biomaterials in the Formation of Photonic Nanostructures

Advanced Science, EarlyView.
Natural organisms create vibrant structural colors through precisely organized nanostructures formed under mild biological conditions. This review explores how cellulose, chitin, corneous beta‐protein, and melanin form complex nanostructures across molecular, mesoscale, and tissue levels.

Localized Hydrogen Release Driven by Mg–Pd Microgalvanic Cells from 3D‐Printed Microneedles Reverses Redox Homeostasis for Psoriasis Treatment

Advanced Science, EarlyView.
A 3D printing microneedle (MP‐MN), loading magnesium‐based micro‐galvanic cells (MP), is designed for improving psoriasis. H2 generated from MP‐MN scavenges ROS and •OH, actives NRF2‐KEAP1 pathway, and decreases inflammation, thereby effectively restoring the oxidative stress homeostasis of psoriatic skin and suppressing the excessive proliferation of ...
