Controllable engineered probiotic microspheres for treating ulcerative colitis: A cascade enzyme‐catalyzed strategy to restore intestinal redox homeostasis

open access: yesBMEMat, EarlyView.
A dual strategy integrating genetic engineering and physical encapsulation was proposed to enhance the cell viability and antioxidant properties of probiotics. The cascade antioxidant enzymes released from probiotic microspheres restore intestinal redox homeostasis by eliminating intestinal reactive oxygen species for ulcerative colitis treatment ...

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

open access: yesBMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Viscoelastic hydrogel potentiates cancer cell stemness and drug resistance through Piezo1‐dependent mechanotransduction

open access: yesBMEMat, EarlyView.
The effects of matrix dynamics on cancer progression remain unclear. Herein, we fabricated a tunable dynamic hydrogel via reversible host–guest crosslinking and demonstrated that high matrix dynamics activate Piezo1 and its downstream PI3K/AKT and Wnt/β‐catenin signaling pathways, thereby enhancing cancer spheroid assembly, elevating cancer stemness ...

Channel‐trap coupled charge modulation in sulfur‐vacancy‐rich nanotransducer for enhanced dual‐mode cancer catalytic therapy

open access: yesBMEMat, EarlyView.
Sulfur vacancy‐rich ZnS–NCx heterojunctions are engineered as dual‐function nanotransducers, in which channel‐trap‐coupled electronic pathways enable efficient capture and transport of ultrasound‐induced piezoelectrons. This vacancy‐mediated regulation simultaneously enhances sonodynamic activity and biomimetic POD/GSHOx catalysis, triggering a self ...

Reversible Cystine Disulfide Scaffolding Enables Carbonyl Sulfide‐Mediated Intramolecular Peptide Bond Formation via Cyclocystine: Implications for Prebiotic Chemistry

open access: yesChemistry – A European Journal, EarlyView.
Cystine is unique among amino acids, in that the disulfide bond can allow intramolecular peptide bond formation. This cyclization offers potential advantages for intramolecular coupling selectivity in prebiotic peptide formation. ABSTRACT Treatment of cystine (the disulfide‐linked dimer of cysteine) with carbonyl sulfide (COS) results in the formation ...
