ROS‐Targeted Nanomotor Therapy in OA: Cartilage Protection and Pain Relief

open access: yesAdvanced Science, EarlyView.
ROS‐responsive NM@MET nanomotors utilize elevated ROS in osteoarthritic joints to promote deep penetration into cartilage and synovium and enable sustained metformin release. By scavenging ROS, regulating NRF2/KEAP1 signaling, protecting chondrocytes, suppressing synovial inflammation, and attenuating nociceptive signaling, NM@MET alleviates pain and ...

Computation‐Guided Tunnel Engineering Enhances O2 Transport and H2O2 Resistance of Fe(II)/α‐Ketoglutarate‐Dependent Dioxygenases

open access: yesAdvanced Science, EarlyView.
This study presents a computational tunnel engineering strategy in Fe(II)/α‐ketoglutarate‐dependent dioxygenases (αKGDs) to enhance oxygen (O2) transport, an essential molecule for αKGDs, and limit hydrogen peroxide (H2O2) entry, an inhibitor from the αKG supply system.

High Tree Species Diversity Promotes Thermal Enhancement Response of Microbial Carbon Use Efficiency

open access: yesAdvanced Science, EarlyView.
ABSTRACT Predicting soil carbon dynamics under warming is constrained by limited understanding of microbial thermal adaptation, particularly whether microbial carbon use efficiency (CUE) can adapt to warming and how plant diversity modulates this response. Using soils from a natural tree species diversity gradient in a subtropical forest, we combined a

Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Assessment of Purslane (Portulaca oleracea L.) Total Oxalate Content, Ascorbic Acid, and Total Organic Acids Using Near-Infrared Spectroscopy

open access: yesPlants
Purslane (Portulaca oleracea L.) has been regaining its reputation as a valuable food and source of nutrients and biologically active compounds, but a high content of oxalates reduces mineral bioavailability and poses nutritional limitations.
