Quantitative Visualization of Intracellular Nanometabolism Using Peak‐Shifted Dual‐State Emissive FRET Nanoprobes

open access: yesAdvanced Science, EarlyView.
This study reveals the long‐elusive intracellular dissolution mechanism of carrier‐free nanomedicines. By utilizing peak‐shifted dual‐state emissive FRET nanoprobes (PDFNPs) that undergo a distinct ratiometric fluorescence peak shift upon disassembly, we achieve real‐time, quantitative tracking of dissolution kinetics in live cells.

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Ciliary Membrane Lipid Homeostasis in Health and Disease

open access: yesAdvanced Science, EarlyView.
This review systematically delineates the distinct lipid landscapes of ciliary membranes, including the spatial organization of phosphoinositides, cholesterol, and sphingolipids. It elucidates how these lipids orchestrate ciliogenesis, signal transduction, and membrane dynamics in cilia beating, and highlights how their dysregulation drives ...

A formulation of thickness optimization for plane stress

open access: yes, 2009
Thickness optimization can be considered as a case of sizing optimization for plane structures. It canalso be used as an intermediate step for topology problems, i.e. we can eliminate the parts where thethickness tends to be zero. This paper is concerned
