Superoxide and superoxide dismutase in red blood cells.

The St. Luke's Hospital gazette, 1976
In 1969 a previously obscure copper protein of red blood cells, erythrocuprein, was shown to catalyse the dismutation of superoxide radicals. Erythrocuprein thus became superoxide dismutase and the object of intensive study. Superoxide dismutase is typically an enzyme of aerobic organisms which utilize oxygen as the major electron acceptor.

Photon-generated carriers excite superoxide species inducing long-term photoluminescence enhancement of MAPbI₃ perovskite single crystals

, 2017
Superoxides, produced by the reaction of O2 with photon-generated electrons, with the assistance of iodine vacancies and lead ions, lead to photoluminescence enhancements in perovskites.

N, S Co‐Doped Carbon Quantum Dots‐Riboflavin Composite Photosensitizers for Enhanced Iontophoresis‐Assisted Corneal Cross‐Linking

Advanced Science, EarlyView.
This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.

Neuroprotective Effect of Aqueous Extract of Berberis vulgaris L. in a Model of Parkinson’s Disease in Rat

Journal of Medicinal Plants, 2010
Background: Parkinson’s disease is a neurodegenerative disease of dopaminergic neurons in substancia nigra. Superoxides formation is one of the main etiologies of the disease, and angiotensin converting enzyme inhibitors (ACEIs) are able to suppress ...

The Endothelial Tyrosine Phosphatase SHP-1 Plays an Important Role for Vascular Haemostasis in TNFα-Induced Inflammation In Vivo

Mediators of Inflammation, 2013
Introduction. Inflammation and endothelium-derived superoxides are important pathomechanisms in atherothrombotic diseases. We could previously show that the tyrosine phosphatase SHP-1 acts as a negative regulator in endothelial superoxide production.

GATA4‐Driven Transcription of HtrA1 Promotes Cellular Senescence in Ménière's Disease and Age‐Related Audio‐Vestibular Dysfunction

Advanced Science, EarlyView.
This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...
