Highly‐Time‐Resolved Measurements of Tryptophan's Distribution and Homeostatic Regulation in Live, Intact Animals

open access: yesAdvanced Science, EarlyView.
Using a novel, aptamer‐based biosensor, here we have performed 20‐s‐resolved, in situ measurements of plasma‐free tryptophan in the jugular veins of live rats (blue). This unprecedented time‐resolution provides insights into the regulation of tryptophan metabolism in live, intact animals.

Antigen‐Detected NMR for Minimal Epitope Engineering and Structure‐Guided Selection of a NaV1.7‐Selective Nanobody

open access: yesAdvanced Science, EarlyView.
A minimal extracellular epitope from voltage‐gated sodium channel NaV1.7 was engineered into an isotope‐labelled antigen for antigen‐detected nuclear magnetic resonance (NMR). Together with AlphaFold2 (AF2), this enabled structure‐guided selection of R4C8, a human NaV1.7‐selective nanobody that labels fixed NaV1.7‐expressing cells and produces staining

Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

open access: yesAdvanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Photocatalytic Reduction of U(Ⅵ) by Hierarchical Macro/Mesoporous Carbon Nitride-Titania Composites

open access: yesHe huaxue yu fangshe huaxue
Photocatalytic technology can use photogenerated electrons to reduce easily soluble U(Ⅵ) to insoluble U(Ⅳ). In this work, hierarchical macro/mesoporous g-C3N4-TiO2 composites were synthesized without the introduction of organic templates or auxiliary ...

Gut Microbiota‐Derived Indole‐3‐Propionic Acid Alleviates Diabetic Osteoporosis Through Nrf2‐Mediated Ferroptosis Suppression

open access: yesAdvanced Science, EarlyView.
Diabetes‐associated dysbiosis is accompanied by reduced Clostridium abundance, impaired microbial tryptophan metabolism, and lower circulating indole‐3‐propionic acid (IPA). Exogenous IPA improves trabecular microarchitecture and bone formation and restores Nrf2‐associated antioxidant signaling in bone marrow mesenchymal stem cells, limiting iron ...
