Senescence-related changes in the antioxidant status of ginkgo and birch leaves during autumn yellowing
(Wiley, Hoboken, 2004)
The antioxidant status of birch and ginkgo leaves during autumnal senescence was characterized by the activities of catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX) and superoxide dismutase (SOD). The contents ...
Kinetics of the hydrogen evolution reaction on Fe-Mo film deposited on mild steel support in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The mechanism and kinetics of the hydrogen evolution reaction were studied. in 1.0 mol dm(-3) NaOH solution on Fe-Mo alloy electrodes prepared by electrodeposition at constant current densities from a pyrophosphate bath. ...
Are leaf hydrogen peroxide concentrations commonly overestimated? The potential influence of artefactual interference by tissue phenolics and ascorbate
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2002)
We have examined the authenticity of two methods for determination of H2O2 in leaf tissue. We show that the high concentrations of ascorbic acid present in leaf extracts interfere with both techniques. In the chromogenic ...
Estimation of neuronal population activity changes in rat cerebellum using one electrode
(Elsevier Science Inc, New York, 2004)
Activity of neuronal populations is usually measured with multielectrode systems. In this paper a procedure is described for estimating population activity changes in rat cerebellar cortex, using one microelectrode. Signals ...
Influence of the common varistor dopants (CoO, Cr2O3 and Nb2O5) on the structural properties of SnO2 ceramics
(Elsevier Science Inc, New York, 2004)
The influence of dopants commonly used in SnO2 varistor ceramics, such as CoO, Cr2O3 or Nb2O5, on the structural properties of SnO2 was investigated. Several SnO2-based ceramics containing only one of the dopants were ...
Electronic and transport properties of contacts between molybdenum sulfide nanowires and gold electrodes
(Amer Inst Physics, Melville, 2008)
We report unique electronic and transport properties of contacts between a molybdenum sulfide nanowire and a gold electrode. The pointlike contacts exhibit a remarkable transparency for the charge carrier injection, which ...
Probing the lignin nanomechanical properties and lignin-lignin interactions using the atomic force microscopy
(Elsevier, Amsterdam, 2001)
By combining atomic force microscopy (AFM) force and environmental scanning electron microscopies (ESEMs), herein we present an evidence for the existence of strong intermolecular forces, which are responsible for holding ...
Photoacoustic properties of sintered NiO
(Carl Hanser Verlag, Munich, 2004)
The thermal diffusivity of NiO pellets was determined by the photoacoustic technique. A NiO powder, with a purity of 99.95%, was pressed into pellets 10 mm in diameter. The average agglomerate size of the NiO powder was ...
Distribution of the Asiatic cyprinid Pseudorasbora parva in Serbia and Montenegro
(Wiley, Hoboken, 2004)
The first record of Pseudorasbora parva in the Balkan region was in 1977 in Sasko Lake, Montenegro and in 1978 it was found in Serbia. Since then, this species has spread to almost all lowland rivers and has become a ...
Anti-tumor effect of Coriolus versicolor methanol extract against mouse B16 melanoma cells: In vitro and in vivo study
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
Numerous studies have shown immunostimulatory and anti-tumor effects of water and standardized aqueous ethanol extracts derived from the medicinal mushroom, Coriolus versicolor, but the biological activity of methanol ...
