Lichen metabolites modulate hydrogen peroxide and nitric oxide in mouse macrophages
(2009-11-20)
The activities of perlatolic acid (1), atranorin (2), and lecanoric acid (3) and their derivatives, such as orsellinates and β-methyl orsellinates obtained by alcoholysis, were assessed for stimulation of the release of ...
Microbicidal activity of N-chlorotaurine in combination with hydrogen peroxide
(2017-12-01)
N-chlorotaurine (NCT) and hydrogen peroxide are powerful endogenous antiseptics. In vivo, the reaction between hydrogen peroxide and metal ions leads to the formation of free hydroxyl radicals, which have an increased ...

Flow injection amperometric determination of hydrogen peroxide in household commercial products with a ruthenium oxide hexacyanoferrate modified electrode
(SPRINGER WIEN, 2009)
Hydrogen peroxide was determined in oral antiseptic and bleach samples using a flow-injection system with amperometric detection. A glassy carbon electrode modified by electrochemical deposition of ruthenium oxide ...
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 ...
Bioactive paper platform for detection of hydrogen peroxide in milk
(2020-02-15)
This paper describes the development and application of a paper-based analytical device (μPAD) for the determination of hydrogen peroxide, an important adulterant in milk. The method employs the reaction between hydrogen ...
Electrogeneration of hydrogen peroxide applied to the peroxide-mediated oxidation of (R)-limonene in organic media
(Pontificia Universidad Católica de Valparaíso, 2007)
Low toxic effects of a whitening strip to cultured pup cells
(2013)
To assess the trans-enamel and trans-dentin toxicity of a 10% hydrogen peroxide (HP) whitening strip to odontoblast-like cells (MDPC-23). Methods: Enamel surfaces of enamel/dentin discs adapted to artificial pulp chambers ...
Dental bleaching with a 10% hydrogen peroxide product: a six-month clinical observation
(2014)
Context: The possibility of bleaching vital teeth with peroxide-based products considerably revolutionized esthetic dentistry. Aim: The aim of this clinical study was to evaluate tooth color change and dental sensitivity ...
