High-Frequency Field Stimulation of Primary Neurons Enhances Ryanodine Receptor-Mediated Ca2+ Release and Generates Hydrogen Peroxide, Which Jointly Stimulate NF-kB Activity
(2011)
Neuronal electrical activity increases intracellular Ca2+ concentration and generates reactive oxygen species.
Here, we show that high frequency field stimulation of primary hippocampal neurons generated Ca2+ signals
with ...
Ethylene production and peroxidase activity in aphid-infested barley
(2001)
The purpose of this work was to investigate whether ethylene is involved in the oxidative and defensive responses of barley to the aphids Schizaphis graminum (biotype C) and Rhopalophum padi. The effect of aphid infestation ...
An improved chemiluminescence method for hydrogen peroxide determination in plant tissues
(SPRINGER, 2006-01)
As a consequence of the increasing importance of hydrogen peroxide in plant metabolism, more efficient methods are required for accurate determinations of its concentration in plant tissue and organs. Here we present a ...
Global and Local Reactivity and Activation Patterns of HOOX (X = H, NO 2, CO2-, SO3-) Peroxides with Solvent Effects
(2003)
A detailed analysis of the global and local reactivity patterns of neutral and charged peroxides, including hydrogen peroxide (HOOH), peroxynitric acid (HOONO2), the peroxymonocarbonic ion (HOOCO2-), and the peroxymonosulfate ...
Possible role of catalase in post-dormancy bud break in grapevines
(URBAN & FISCHER VERLAG, BRANCH OFFICE JENA, 2005-03)
Changes in the activity of catalase (Cat) and in the levels of H2O2 were followed throughout dormancy in buds of grapevines (Vitis vinifera L.). In grapevines grown in the Elqui valley in Chile, a region with warm-winters, ...
High-frequency field stimulation of primary neurons enhances ryanodine receptor-mediated Ca2+ release and generates hydrogen peroxide, which jointly stimulate NF-κB activity
(2011)
Neuronal electrical activity increases intracellular Ca2+ concentration and generates reactive oxygen species. Here, we show that high frequency field stimulation of primary hippocampal neurons generated Ca 2+ signals with ...
A novel approach for in-office tooth bleaching with 6 % H2O2/TiO_N and LED/laser system—a controlled, triple-blinded, randomized clinical trial
(Springer London, 2016)
The purpose of this randomized, parallel, tripleblinded clinical trial was to compare efficacy and tooth sensitivity (TS) after use of an in-office bleaching agent of 6 %
hydrogen peroxide containing nanoparticles of ...
One-year bleaching efficacy using two HP products with different pH: A double-blind randomized clinical trial
(Blackwell, 2019)
Objectives: This split-mouth, double-blind, randomized clinical trial evaluated the
1-year bleaching efficacy produced by two hydrogen peroxide gels with different pHs.
Materials and Methods: Twenty-eight patients were ...
Effect of the Dispersing Agent on the Electrochemical Response of Glassy Carbon Electrodes Modified with Dispersions of Carbon Nanotubes
(2012)
The electrochemical response of a glassy carbon electrode modified with carbon nanotubes (CNT) dispersed in two solvents, water and DMF, and two polymers, chitosan and Nafion is reported. The films were homogeneous when ...
From birth to death: a role for reactive oxygen species in neuronal development
(Elsevier, 2018-08)
Historically, ROS have been considered toxic molecules, especially when their intracellular concentration reaches high values. However, physiological levels of ROS support crucial cellular processes, acting as second ...
