Ultracytochemical localization of hydrogen peroxide production by dental plaque bacteria
(1998)
This study looked for evidence of in vitro hydrogen peroxide (HP) synthesis in human dental plaque, using an ultracytochemical technique that included incubation in a CeCl3-rich medium. Supragingival dental plaque was ...
Co2SnO4/Carbon nanotubes composites: A novel approach for electrochemical sensing of Hydrogen Peroxide
(Wiley-V C H Verlag GMBH, 2018)
For the first time Co2SnO4 (CTO)/Carbon nanotubes (CNT) composites were prepared and used to modify glassy carbon electrodes for the amperometric determination of hydrogen peroxide. The catalytic activity of composites ...
A systematic electronic structure study of the O–O bond dissociation energy of hydrogen peroxide and the electron affinity of the hydroxyl radical
(Springer New York LLC, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Hydroxyl radical reduction and peroxide bond breaking in hydrogen peroxide are reactions involved in various processes such as the Fenton reaction, which has ...
Reactivity descriptors for Cu bis-phenanthroline catalysts for the hydrogen peroxide reduction reaction
(Pergamon-Elsevier Science, 2020)
Following previous studies where the metal-centered redox potentials of MN4 complexes are proposed as a reactivity descriptor for different electrochemical reactions, in the present work we expand this idea to a series of ...
Co2SnO4 / Carbon paste electrode as electrochemical sensor for hydrogen peroxide
(Sociedad Chilena de Química, 2017)
Hydrogen peroxide (H2O2) plays an important role as an intermediary in different biological, chemical and environmental systems. It has been widely used as an oxidizing and antimicrobial agent, in germicides production and ...
Can an LED-laser hybrid light help to decrease hydrogen peroxide concentration while maintaining effectiveness in teeth bleaching?
(Institute of Physics Publishing, 2015)
The aim of this study was to compare the bleaching efficacy of 35% hydrogen peroxide and 15% hydrogen peroxide with nitrogen-doped titanium dioxide catalysed by an LED-laser hybrid light. We studied 70 patients randomized ...
Bactericidal efficacy of hydrogen peroxide on Cutibacterium acnes
(British Editorial Society of Bone and Joint Surgery, 2019)
The purpose of this study was to examine the bactericidal efficacy of hydrogen peroxide (H 2 o 2 ) on Cutibacterium acnes (C. acnes). We hypothesize that H 2 o 2 reduces the bacterial burden of C. acnes. Methods The effect ...
Comparative effects of superoxide anion and hydrogen peroxide on microsomal and cytosolic glutathione S-transferase activities of rat liver
(2010)
Glutathione S-transferases (GSTs) are isoenzymes occurring in the cytoplasm and as integral membrane proteins. In addition to their role in drug metabolism by conjugating electrophilic and lipophilic compounds with glutathione ...
Hydrogen peroxide increases during endodormancy and decreases during budbreak in grapevine (Vitis vinifera L.) buds
(MDPI, 2021)
Changes in the level of hydrogen peroxide (H2O2) is a good indicator to monitor fluctuations in cellular metabolism and in the stress responses. In this study, the changes in H2O2 content during bud endodormancy (ED) and ...
Redox status affects the catalytic activity of glutamyl-tRNA synthetase
(Academic Press Inc., 2010)
Glutamyl-tRNA synthetases (GluRS) provide Glu-tRNA for different processes including protein synthesis, glutamine transamidation and tetrapyrrole biosynthesis. Many organisms contain multiple GluRSs, but whether these ...
