Superoxide dismutase inhibitor screening and characterization using ¹?F NMR [PDF]

, 2010
Superoxide dismutase enzymes (SOD) catalyze the disproportionation of superoxide to form molecular oxygen and hydrogen peroxide in a cyclic mechanism. SODs prevent the formation of hydroxyl radicals, preventing apoptosis.

A Hydrogen‐Releasing Nanozyme Engineers a Mitochondrial ROS Amplifier for Self‐Sustaining Catalytic Immunotherapy

Advanced Science, EarlyView.
We developed a RhPd‐H nanozyme that integrates enhanced POD‐mimetic catalytic activity with thermally triggered H2 release. H2 shields and reprograms mitochondria to continuously leak endogenous ·O2−. This dual‐path ROS spatially and temporally disrupts redox homeostasis, inducing persistent oxidative stress for tumor suppression and antitumor immunity,

Bioadhesive Hydrogel With Polyphenol‐Armored Nanogene Rejuvenates Chondrocyte Senescence for Aged Osteoarthritis Therapy

Advanced Science, EarlyView.
An adhesive hydrogel depot with polyphenol‐armored nanogenes is developed for treating aged osteoarthritis. This system maintains miR‐140 bioactivity, prolongs its intra‐articular retention, and enhances transfection into chondrocytes, leading to the downregulation of senescence‐associated pathways.

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

Advanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Hyperlipidemia Aggravates Alveolar Bone Loss via Periodontal Ligament Stem Cell Ferroptosis Through GSK3β Dependent Ubiquitin‐Mediated NRF2 Degradation

Advanced Science, EarlyView.
Lipid metabolic stress triggers ferroptosis in PDLSCs through the GSK3β/NRF2 pathway, thereby aggravating periodontal bone loss. Upregulated GSK3β promotes NRF2 ubiquitination and proteasomal degradation via β‐TrCP, suppressing NRF2 nuclear translocation and antioxidant target expression.

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
