EPR Spin-Trapping and Spin-Probing Spectroscopy in Assessing Antioxidant Properties: Example on Extracts of Catkin, Leaves, and Spiny Burs of Castanea sativa
(Springer, New York, 2009)
Electron paramagnetic resonance (EPR) spin-trapping and spin-probing techniques were applied to determine antioxidant activity of extracts of catkin, leaves, and spiny burs of Castanea sativa against physiologically relevant ...
In vitro avarol does affect the growth of Candida sp.
(Taylor & Francis Ltd, Abingdon, 2016)
This work extends in vitro screening of antimicrobial activity of avarol, the marine natural product firstly isolated from the Mediterranean sponge Dysidea avara. Its anticandidial activity was evaluated by microdilution ...
Magneli phase titanium oxides as catalyst support - Electrochemical behavior of Ebonex/Pt catalysts
(Journal of New Materials for Electrochemical Systems, 2006)
The impregnation method has been applied to synthesize platinum nanoparticles on Magneli phase titanium oxide powder (Ebonex). Surface area of the Ebonex support was determined by BET technique. Distribution and morphology ...
A method for detecting the effect of magnetic field on activity changes of neuronal populations of Morimus funereus (Coleoptera, Cerambycidae)
(Wiley-Liss, Hoboken, 2007)
Modification of a new method for detecting changes in the activities of neuronal population and the nearest neuron is described. Preliminary measurements of the influence of a static magnetic field (2 mT) on neuronal ...
Changes in peroxidase activity and isoenzymes in spruce needles after exposure to different concentrations of cadmium
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
We studied the guaiacol peroxidase activity, isoenzyme pattern and metal content in the needles of 2-year-old spruce grown on soils supplemented with cadmium concentrations from 1 to 21 mg kg(-1). Following exposure to ...
A comparative study of enzymatically and photochemically polymerized artificial lignin supramolecular structures using environmental scanning electron microscopy
(Academic Press Inc Elsevier Science, San Diego, 2000)
Environmental scanning electron microscopy images of the self-assembled structures of enzymatically (DHP) and photochemically polymerized (PCP) artificial lignin are herein presented. Differences in the structural organization ...
Inhibition of catalase by sulfite and oxidation of sulfite by H2O2 cooperating with ascorbic acid
(Harwood Academic Publishers GmbH, 1999)
An oxidative detoxification of sulfite, which originates from sulfur dioxide taken up into a leaf, has not yet been fully understood. In this study, we discuss that redox reactions between sulfite and H2O2 have an important ...
Senescence-related changes in catalase, peroxidase and ascorbic acid level in ginkgo and birch leaves during autumn yellowing
(Taylor & Francis Ltd, Abingdon, 2003)
Characterization of NAD-dependent malate dehydrogenases from spinach leaves
(Springer Wien, Wien, 2008)
Spinach leaves were used to extract isoforms of NAD-dependent malate dehydrogenase (NAD-MDH) (EC 1.1.1.37), either soluble or bound to microsomal, plasma, or chloroplast envelope membranes. All fractions were subjected to ...
Consecutive differences as a method of signal fractal analysis
(World Scientific Publ Co Pte Ltd, Singapore, 2005)
We propose a new method for calculating fractal dimension (DF) of a signal y(t), based on coefficients m(y)((n)), mean absolute values of its nth order derivatives (consecutive finite differences for sampled signals). We ...
