DFT Investigation of Biocatalytic Mechanisms from pH-Driven, Multi-Enzyme, Biomimetic Behavior in CeO2 [PDF]
, 2021 There is considerable interest in the pH-dependent, switchable, biocatalytic properties of cerium oxide (CeO2) nanoparticles (CeNPs) in biomedicine, where these materials exhibit beneficial antioxidant activity against reactive oxygen species (ROS) at basic physiological pH but cytotoxic prooxidant activity in acidic cancer cell pH microenvironment ...

The trail to superoxide dismutase [PDF]
Protein Science, 1998 City College of New York + Cornell Medical School + Duke. While a youngster, I was enthralled by the miracle of insect metamorphosis and followed the transformations of pet caterpillars to pupae and then to gloriously beautiful butterflies and moths. This led naturally to an interest in biology. but mere description was not totally satisfying.

Reaction Cycles of Halogen Species in the Immune Defense: Implications for Human Health and Diseases and the Pathology and Treatment of COVID-19 [PDF]
Cells 2020, 9(6), 1461, 2020 There is no vaccine or specific antiviral treatment for COVID-19. One current focus is drug repurposing research, but those drugs have limited therapeutic efficacies and known adverse effects. The pathology of COVID-19 is essentially unknown. It is therefore challenging to discover a successful treatment to be approved for clinical use.

Superoxide Dismutase Activities in Plasma of Patients with Breast Cancer
Archives of Breast Cancer, 2014 Background: Superoxide radicals are produced during oxidative metabolic processes, and removed by superoxide dismutase (SOD) enzymes. Controversial results have been reported regarding the tissue and plasma concentration of SOD in patients with breast ...

High expression of antioxidant proteins in dendritic cells: possible implications in atherosclerosis [PDF]
Mol Cell Proteomics 5 (04/2006) 726-36, 2006 Dendritic cells (DCs) display the unique ability to activate naive T cells and to initiate primary T cell responses revealed in DC-T cell alloreactions. DCs frequently operate under stress conditions. Oxidative stress enhances the production of inflammatory cytokines by DCs.

Increased peripheral lipid clearance in an animal model of amyotrophic lateral sclerosis [PDF]
The Journal of Lipid Research 48, 7 (07/2007) 1571-1580, 2007 Amyotrophic lateral sclerosis (ALS) is the most common adult motor neuron disease, causing motor neuron degeneration, muscle atrophy, paralysis, and death. Despite this degenerative process, a stable hypermetabolic state has been observed in a large subset of patients.

Superoxide dismutase in anaerobes: survey [PDF]
Applied and Environmental Microbiology, 1978 Superoxide dismutase (SOD) was present in 23 of 28 strains of the genus Bacteroides tested. Several clostridia, anaerobic cocci, and anaerobic, grampositive, nonsporing rods contained measureable SOD, but the frequency of SOD occurrence was much lower than in the bacteroides.
