14‐3‐3γ Protects Against Postoperative Cognitive Dysfunction by Regulating Tau Thr205 Phosphorylation and Synaptic Integrity

open access: yesAdvanced Science, EarlyView.
Integrative multi‐cohort analyses identify 14‐3‐3γ as a biomarker and regulator of cognitive vulnerability. Experimental studies show that 14‐3‐3γ loss is associated with Tau Thr205 phosphorylation, synaptic dysfunction, and cognitive impairment, while genetic overexpression or pharmacological stabilization of 14‐3‐3γ confers protective effects in ...

Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

open access: yesAngewandte Chemie, EarlyView.
Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...

Mechanophore‐Based Multichannel Colorimetric Force Sensors: Ultrasound‐Driven Stress and Strain Quantification

open access: yesAdvanced Science, EarlyView.
ABSTRACT Mechanophores with mechanochromic properties have attracted significant attention as force‐responsive materials for structural sensing. However, their applications remain mainly limited to qualitative force visualization, as direct and quantitative extraction of mechanical parameters such as stress and strain from mechanochromic responses has ...
