Hollow Cu2O Nanozymes Enhance Probiotic Therapy for Colitis via Redox Homeostasis and TXNIP/NLRP3 Inflammasome Inhibition

Advanced Science, EarlyView.
Hollow cuprous oxide (H‐Cu2O) nanozymes feature enlarged catalytic surfaces for superior reactive oxygen species (ROS) scavenging. By efficiently neutralizing mucosal ROS, H‐Cu2O directly suppresses the TXNIP/NLRP3 inflammasome axis and restores intestinal epithelial barrier integrity.

Gut Microbial Release of Ferulic Acid From Germinated Quinoa Alleviates Obesity‐Associated Cognitive Impairment by Activating Hippocampal Mitophagy Associated with PINK1/Parkin Pathway

Advanced Science, EarlyView.
Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Interference of ATP‐Binding Cassette Transporter by Functional Nano‐Delivery System for High Efficiency Management of Insecticide‐Resistant Nilaparvata lugens

Advanced Science, EarlyView.
A ZIF‐90 nanocarrier delivers dinotefuran and suppresses NlABCG3 and NlABCH1 in resistant Nilaparvata lugens. This system combines pH/ATP‐triggered release with enhanced foliar retention, improving efficacy while sparing honeybees and promoting rice growth, offering a promising resistance‐breaking strategy.

Rhoifolin Alleviates Ulcerative Colitis by Targeting NMNAT1 and Activating SIRT1‐FOXO1 Signaling to Enhance ILC3s Effector Function

Advanced Science, EarlyView.
Rhoifolin directly targets NMNAT1, thereby activating nicotinamide salvage pathway and promoting intracellular NAD+ biosynthesis. Elevated NAD+ levels enhance SIRT1 activity, leading to FOXO1 deacetylation and nuclear translocation. Nuclear FOXO1 subsequently binds to the IL‐22 promoter, upregulating IL‐22 transcription and potentiating ILC3 effector ...
