An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

Advanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

5,6,7,8-tetrahydroneopterin (NH4) Acts like an Endogenous Superoxide Dismutase

Pteridines, 1996
The protective effect of 5,6,7,8-tetrahydroneopterin (NH.) against radiation injury in mice was studied. (C57BL/6x A/J)F1 mice received whole body irradiation with a single fatal dose of 8.0 Gy X-ray.

Superoxide dismutase triggers activation of primed platelets

, 1991
Superoxide dismutase (SOD) triggers activation of human platelets exposed to subthreshold concentrations of arachidonic acid and collagen. The subthreshold concentrations used are not able to activate platelets but "prime" platelets to be activated by ...

D4F‐Functionalized Ceria Nanozyme‐CasRx Platform Suppresses STING and Reprograms the Renal Immune Niche in Acute Kidney Injury

Advanced Science, EarlyView.
D4F‐functionalized ceria nanozyme–CasRx nanoparticles preferentially target renal macrophages through SR‐B1‐mediated uptake in ischemia–reperfusion injury. Ceria scavenges excessive ROS, while CasRx silences STING signaling, shifting macrophages toward a less inflammatory, pro‐resolving state and increasing the proportion of regulatory T cells.

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

Advanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Studies on superoxide dismutase inhibition and application of methods to study metal ion participation in complication of diabetes [PDF]

, 2012
Studies on Superoxide Dismutase Inhibition We used NMR relaxation rates to study reactions of the enzyme superoxide dismutase (SOD) with low molecular weight polyphenolic compounds. While the compounds appeared to inhibit SOD, we discovered evidence that

Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease

Advanced Science, EarlyView.
A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

A New Method for the Purification of Cu-Zn Superoxide Dismutase from Human Erythrocytes [PDF]

Iranian Journal of Public Health, 2005
The human erythrocyte is a rich raw material for the purification of Cu-Zn superoxide dismutase (SOD). We applied a simple and rapid procedure for the purification of SOD from human erythrocytes by ion exchange chromatography.
