Relevance of the capacity of phosphorylated fructose to scavenge the hydroxyl radical
(Elsevier Sci Ltd, Oxford, 2009)
The hydroxyl radical ((OH)-O-center dot) has detrimental biological activity due to its very high reactivity. Our experiments were designed to determine the effects of equimolar concentrations of glucose, fructose and ...
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 ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
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 ...
Antioxidant Properties of Phenolics in Castanea sativa Mill. Extracts
(University of Zagreb, 2009)
Using electron paramagnetic resonance (EPR) spectroscopy, antioxidant properties of chestnut extracts have been investigated as a source of phenolic compounds. In addition to their high antioxidant activities against ...
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 ...
Fenton reaction produces hydrogen radical (center dot H) in chemical and biological systems
(Taylor & Francis Ltd, Abingdon, 2006)
Far infrared reflectance of sintered Zn2TiO4
(Springer, New York, 2008)
Zinc-titanate ceramics were obtained by initial mechanical activation in a high-energy planetary mill for 15 min followed by sintering at temperatures 900-1100 degrees C for 2 h. Room temperature far infrared reflectivity ...
Effects of xanthine derivatives on electroretinographic responsiveness
(Elsevier, Amsterdam, 2000)
In view of the use of synthetic propentofylline (PPF) as a protective agent in brain ischemia, its possible side effects on vision capacities have been explored by electroretinography in comparative experiments with ...
Oxygen and light accelerate recovery from SO2-induced inhibition of leaf photosynthesis and from cytoplasmic acidification
(Elsevier GmbH, 2000)
Leaves of several plant species were illuminated either in air or in a gas atmosphere with reduced oxygen content, and photosynthesis and transpiration were recorded after brief exposure to high concentrations of SO2. ...
