Aquaporins in poplar: What a difference a symbiont makes!
(Springer, New York, 2005)
The formation of ectomycorrhizas, a tight association between fine roots of trees and certain soil fungi, improves plant nutrition in a nutrient-limited environment and may increase plant survival under water stress ...
The effect of anoxia on PolyP content of Phycomyces blakesleeanus mycelium studied by P-31 NMR spectroscopy
(New York Acad Sciences, New York, 2005)
The effect of anoxia and the respiratory chain inhibitors azide and cyanide on the polyphosphate content of Phycomyces was studied by in vivo (31)p NMR spectroscopy. Anoxia was manifested by a decrease of core polyphosphates ...
Nonenzymatic reaction of dihydroxyacetone with hydrogen peroxide enhanced via a Fenton reaction
(New York Acad Sciences, New York, 2005)
An analysis of the reaction of dihydroxyacetone with hydrogen peroxide was performed using HPLC with electrochemical and spectrophotometric detection and EPR spectroscopy of the reactants and products. Glycolate production ...
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 ...
Acid activation of bentonite clay in conditions of water deficiency
(Silicates Industriels, 2005)
The methods of X-ray diffraction, FTIR, electron microscopy, BET, CEC and others were used for investigation of bentonite activation with hydrochloric acid in conditions of water deficiency. It was established that during ...
Modeling of the migration of the European glass eel
(New York Acad Sciences, New York, 2005)
The characteristics of glass eel migration at the mouth of river Bojana have been investigated by seasonal field studies from February to April 1998. Samples were collected by two fyke nets, one on each riverside, for 12 ...
Fractal analysis of rat brain activity after injury
(Springer Heidelberg, Heidelberg, 2005)
With application of the Higuchi algorithm, fractal dimension (FD) values of the electrocortical activity of the rat parietal cerebral and paravermal cerebellar cortex were calculated, before and after unilateral discrete ...
Barium strontium titanate powders prepared by spray pyrolysis
(Elsevier Science Sa, Lausanne, 2005)
Ultasonic spray pyrolysis (SP) has been investigated for the production of the barium strontium titanate (BST) powders from the polymeric precursors. The processing parameters, such as flux of aerosol and temperature profile ...
Detection of hydrogen atom adduct of spin-trap DEPMPO. The relevance for studies of biological systems
(Amer Chemical Soc, Washington, 2005)
We proposed EPR spectroscopy using spin-trap DEPMPO as a novel method for the detection of a hydrogen atom (H-center dot) produced by chemical and biological systems. In complex EPR spectra of DEPMPO adducts in biological ...
P-31 NMR spectroscopy and polarographic combined study of erythrocytes treated with 5-fluorouracil - Cardiotoxicity-related changes in ATP, 2,3-BPG, and O-2 metabolism
(New York Acad Sciences, New York, 2005)
Antineoplastic drug 5-fluorouracil (5-FU) frequently shows cardiotoxic effects, the mechanism of which has not yet been elucidated. The objective of the present study was to explore effects of 5-FU on metabolism of ATP, ...
