Oral Bioinspired Peroxisome‐Engineered Probiotics for Modulating Gut Microbiota Homeostasis and Alleviating Cardiac Chemotherapy Toxicity

open access: yesAdvanced Science, EarlyView.
This study developed an oral bioinspired peroxisome‐engineered probiotic (BPEP) by anchoring lipid‐encapsulated ruthenium nanozymes onto Escherichia coli Nissle 1917, utilizing probiotics to deliver nanozymes to the intestinal barrier for reactive oxygen species/reactive nitrogen species elimination, tight junction restoration, and gut microbiota ...

Tailored Porous Bimetallic Nanozyme Platform for Full‐Cycle Therapeutics of Intestinal Ischemia/Reperfusion

open access: yesAdvanced Science, EarlyView.
ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly

Evaluation of Inflammatory and Oxidative Markers and Their Diagnostic Value in Schizophrenia

open access: yesBrain Sciences
Objective: Schizophrenia is a chronic psychiatric disorder associated with increased oxidative stress. We aimed to investigate serum myeloperoxidase (MPO), catalase (CAT), and malondialdehyde (MDA) levels and their diagnostic value in schizophrenia ...

Biomimetic Nanoplatform for Targeted Glioblastoma Therapy via Concurrently Triggering GPX4/DHODH Mediated Ferroptosis

open access: yesAdvanced Science, EarlyView.
Considering the great challenge in Glioblastoma multiforme (GBM) treatment, the authors designed and synthesized a multifunctional nanoplatform that effectively induced ferroptosis by synergetically inhibiting intrinsic intrisinc anti‐ferroptosis proteins, GPX4 & DHODH, and realized excellent in vitro and in vivo anti‐GBM effect.

Bifunctional Artificial Enzymes‐Loaded Microgels With LOX‐ and CAT‐Like Activities for Metabolic Reprogramming and Scarless Wound Repair

open access: yesAdvanced Science, EarlyView.
A bifunctional lactate oxidase‐like and catalase‐like artificial enzyme (Metazyme) is integrated into a rod‐shaped microgel (MetaRgel) to enable cascade lactate oxidation and oxygen regeneration. By reprogramming the wound metabolic microenvironment, MetaRgel alleviates excessive lactate accumulation, oxidative stress, hypoxia, and inflammation ...

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

open access: yesAdvanced Science, EarlyView.
Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.
