Free radicals and antioxidants at a glance using EPR spectroscopy
(Taylor & Francis Ltd, Abingdon, 2011)
The delicate balance between the advantageous and detrimental effects of free radicals is one of the important aspects of human (patho)physiology. The controlled production of reactive oxygen and nitrogen species has an ...
Electrochemical versus Spectrophotometric Assessment of Antioxidant Activity of Hop (Humulus lupulus L.) Products and Individual Compounds
(Amer Chemical Soc, Washington, 2013)
Antioxidant (AO) activity of extracts of hop cones (Serbian domestic varieties) and commercial hop products (Saaz, Spalter, Spalter select, and Magnum pellets) was determined by parallel application of recently developed ...
Leaf vitamin C contents modulate plant defense transcripts and regulate genes that control development through hormone signaling
(Amer Soc Plant Biologists, Rockville, 2003)
Vitamin C deficiency in the Arabidopsis mutant vtc1 causes slow growth and late flowering. This is not attributable to changes in photosynthesis or increased oxidative stress. We have used the vtc1 mutant to provide a ...
Mechanism of Fe uptake by the leaf symplast: Is Fe inactivation in leaf a cause of Fe deficiency chlorosis?
(Springer, Dordrecht, 1999)
The mechanism of iron (Fe) uptake from the leaf apoplast into leaf mesophyll cells was studied to evaluate the putative Fe inactivation as a possible cause of Fe deficiency chlorosis. For this purpose, sunflower (Helianthus ...
Light-induced transient ion flux responses from maize leaves and their association with leaf growth and photosynthesis
(Wiley, Hoboken, 2005)
Net fluxes of H+, K+ and Ca2+ ions from maize (Zea mays L.) isolated leaf segments were measured non-invasively using ion-selective vibrating microelectrodes (the MIFE technique). Leaf segments were isolated from the blade ...
Spectral and dose dependence of light-induced ion flux responses from maize leaves and their involvement in leaf expansion growth
(Oxford Univ Press, Oxford, 2007)
Two types of segments (intact leaf tissue and isolated mesophyll tissue respectively) were isolated from basal (still growing) and tip (non-growing) maize leaf regions. The leaf segments were exposed to different light ...
Study of self-assembly of the lignin model compound on cellulose model substrate
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
Full Paper: Herein we report a topographical study of the supramolecular organization of enzymatically polymerized lignin model compound - dehydrogenative polymer (DHP) of coniferyl alcohol - on cellulose substrate, using ...
Effects of 5-fluorouracil on erythrocytes in relation to its cardiotoxicity: Membrane structure and functioning
(Amer Chemical Soc, Washington, 2005)
In the present study, we showed that the antineoplastic drug 5-fluorouracil (5-FU) induces in vitro exposure-time/dose-dependent changes on the level of an erythrocyte's morphology, ionic balance, and membrane fluidity. ...
Senescence- and drought-related changes in peroxidase and superoxide dismutase isoforms in leaves of Ramonda serbica
(Oxford Univ Press, Oxford, 2006)
Ramonda sp. (Gesneriaceae) is an endemic and relic plant in a very small group of poikilohydric angiosperms that are able to survive in an almost completely dehydrated state. Senescence- and drought-related changes in the ...
Electroretinographic evaluation of spectral sensitivity in yellow and silver eels (Anguilla anguilla)
(Cambridge Univ Press, New York, 1998)
Although differences in visual pigments between developmental stages of the European eel are well known, the expected differences in spectral sensitivity have not been demonstrated at the electrophysiological level. In ...
