Identification and partial characterization of an extracellular manganese-dependent peroxidase in Armillaria ostoyae and Armillaria mellea

, 1992
National audienceAbstract Laccase and manganese-dependent peroxidase (Mn peroxidase) activities were detected in the culture media of Armillaria ostoyae and A. mellea. Mn peroxidase was produced in significantly higher quantity by the A. ostoyae isolates

Bimetallic Plasmonic Nanozyme‐Based Microneedle for Synergistic Ferroptosis Therapy of Melanoma

Advanced Science
Melanoma is the most common malignant skin tumor, characterized by complexity, invasiveness, and heterogeneity. Conventional therapies often yield poor outcomes, posing significant clinical challenges.

Bifunctional catalase-peroxidase KatB drives direct and indirect Mn(II) oxidation in genetically engineered bacteria: Synergistic biochar immobilization enhances wastewater remediation

Environment International
Manganese (Mn) pollution threatens ecosystems and human health. Microbial Mn(II) oxidation is a promising Mn(II) removal strategy, which converts soluble Mn(II) into insoluble Mn(III/IV) oxides.

The preparation and characterisation of novel microperoxidase biocatalysts [PDF]

, 1987
Microperoxidases are haem oligopeptides, derived from the proteolytic digestion of cytochrome c, possessing peroxidase activity. They are termed "microperoxidases" in contrast to other relatively large peroxidases such as horseradish peroxidase.

Reactions of "hybrid" Mn-peroxidase of the white rot fungus Panus tigrinus with benzylic alcohols in the presence of mediators

, 2004
"Hybrid" Mn-peroxidase (hMnP) isolated from the white rot fungus Panus tigrinus 8/18 was studied with respect to its reactions with veratryl alcohol in the presence of typical laccase mediators in the reaction mixture.

Self-oxygenating PCN-224(Mn) co-delivers sorafenib and plumbagin to boost chemo-photodynamic therapy in hepatocellular carcinoma

International Journal of Pharmaceutics: X
Tumor hypoxia is a major barrier to oxygen-dependent photodynamic therapy (PDT), markedly limiting its therapeutic efficacy in hepatocellular carcinoma (HCC).

Effect of Foliar Nutrition on Post-Harvest of Onion Seed under Sandy Soil and Saline Irrigation Water Conditions

International Journal of Horticultural Science, 2013
Foliar application has been determined to be an effective nutrients delivery strategy in vegetable and fruits. The enhancement of vegetable and fruit yields affected by foliar nutrients application has been recognized in previously conducted studies with

Influence of hyperhomocysteinemia on the cellular redox state - Impact on homocysteine-induced endothelial dysfunction [PDF]

, 2003
Hyperhomocysteinemia is an independent risk factor for the development of atherosclerosis. An increasing body of evidence has implicated oxidative stress as being contributory to homocysteines deleterious effects on the vasculature.
