Assembly Processes under Severe Abiotic Filtering: Adaptation Mechanisms of Weed Vegetation to the Gradient of Soil Constraints
(Public Library Science, San Francisco, 2014)
Questions: Effects of soil on vegetation patterns are commonly obscured by other environmental factors; clear and general relationships are difficult to find. How would community assembly processes be affected by a substantial ...
Extracellular iron diminishes anticancer effects of vitamin C: An in vitro study
(Nature Publishing Group, London, 2014)
In vitro studies have shown that hydrogen peroxide (H2O2) produced by high-concentration ascorbate and cell culture medium iron efficiently kills cancer cells. This provided the rationale for clinical trials of high-dose ...
Effect of long-term cyanide exposure on cyanide-sensitive respiration and phosphate metabolism in the fungus phycomyces blakesleeanus
(Srpsko biološko društvo, Beograd, i dr., 2014)
The effects of long-term exposure (5 h) of Phycomyces blakesleeanus mycelium to 5 mM KCN on respiration and phosphate metabolites were tested. Exposure to cyanide, antimycin A and azide lead to a decrease in the activity ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
Characterization of the Alkoxide-based Sol-gel Derived La9.33Si6O26 Powder and Ceramic
(Slovensko Kemijsko Drustvo, Ljubljana, 2014)
In this study, we report on the acid-catalysed synthesis of La9.33Si6O26 from lanthanum nitrate or acetate and silicon ethoxide (TEOS) in the ethanol solvent, upon the transition from liquid to amorphous and crystalline ...
Ouabain modulation of snail Br neuron bursting activity after the exposure to 10 mT static magnetic field revealed by Higuchi fractal dimension
(General Physiol And Biophysics, Bratislava, 2014)
Aim of this study was to investigate the application of normalized mean of the empirical Higuchi fractal dimension (FD) distributions, as a new approach to analyze the spontaneous bioelectrical activity of garden snail ...
Effect of phenol on germination capacity and polyphenol oxidase, peroxidase and catalase activities in lettuce
(Srpsko biološko društvo, Beograd, i dr., 2014)
In this study we examined the activities of polyphenol oxidase (PPO) and antioxidant enzymes, peroxidase (POX) and catalase (CAT) during lettuce seed germination at different concentrations of phenol. Out of eleven varieties ...
Using Higuchi’s fractal dimension in fine analysis of the effects of 2.7 mt and 10 mt static magnetic fields on the complex bursting activity of the snail br neuron
(Srpsko biološko društvo, Beograd, i dr., 2014)
The components of complex bioelectrical activity - action potential (AP), interspike interval (ISI) and the quiet interburst interval (IBI), along with the effects of 2.7 mT and 10 mT static magnetic fields, were identified ...
Synthesis and characterization of mu-hydroxido- and mu-polycarboxylato-bridged iron(III) complexes with 2,2 '-bipyridine
(Srpsko hemijsko društvo, Beograd, 2014)
Four novel polymeric iron(III) complexes with 2,2'-bipyridine (bipy) and different aromatic polycarboxylato ligands as anions of phthalic (pht), isophthalic (ipht), terephthalic (tpht) and pyromellitic (pyr) acid were ...
Spectrofluorimetric determination of quercetin in pharmaceutical dosage forms
(Soc Chemists Technologists Madeconia, Skopje, 2014)
A simple, accurate and precise method based on the fluorescence properties of the aluminum(III)-quercetin complex, for the determination of quercetin, has been developed and validated. The complex has strong emission at ...
