Carbon allocation from source to sink leaf tissue in relation to flavonoid biosynthesis in variegated Pelargonium zonale under UV-B radiation and high PAR intensity
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2015)
We studied the specific effects of high photosynthetically active radiation (PAR, 400-700 nm) and ecologically relevant UV-B radiation (0.90 W m(-2)) on antioxidative and phenolic metabolism by exploiting the green-white ...
Effects of the static and ELF magnetic fields on the neuronal population activity in Morimus funereus (Coleoptera, Cerambycidae) antennal lobe revealed by wavelet analysis
(Elsevier Science Inc, New York, 2015)
To study the influence of a static magnetic field (SMF, 2 mT) and extremely low frequency magnetic field (ELF MF, 50 Hz, 2 mT) on the neuronal population activity, the experiments were performed on adult longhorn beetles ...
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 ...
Potential of Teucrium chamaedrys L. to modulate apoptosis and biotransformation in colorectal carcinoma cells
(Elsevier Ireland Ltd, Clare, 2019)
Ethnopharmacological relevance: Teucrum chamaedrys L. is one of the known medicinal plants, useful for treatment of various health problems, especially digestive. In this study, we investigated methanol, ethyl-acetate and ...
A contribution to the estimation of berry fruits quality
(Elsevier, Amsterdam, 2019)
This study aimed to estimate the quality (in terms of standard chemical parameters, total antioxidative activity /AO/ and thermal properties) of the fresh strawberry (Fragaria xananassa L. Duch.), raspberry (Rubus idaeus ...
Designing topological defects in 2D materials using scanning probe microscopy and a self-healing mechanism: a density functional-based molecular dynamics study
(IOP Publishing Ltd, Bristol, 2017)
Engineering of materials at the atomic level is one of the most important aims of nanotechnology. The unprecedented ability of scanning probe microscopy to address individual atoms opened up the possibilities for ...
Structure and enhanced antimicrobial activity of mechanically activated nano TiO2
(Wiley, Hoboken, 2019)
Titanium dioxide is a photocatalyst, known not only for its ability to oxidize organic contaminants, but also for its antimicrobial properties. In this article, significant enhancement of the antimicrobial activity of TiO2 ...
Analysis of anal intraepithelial neoplasia images using 1d and 2d higuchi's fractal dimension methods
(World Scientific Publ Co Pte Ltd, Singapore, 2018)
The ILF (Image Landscapes' Fractal Dimension) method and DF2d method obtained by a 2D generalization of Higuchi's algorithm were applied to a set of 120 digital histological images of Anal Intraepithelial Neoplasia (AIN). ...
