Fluctuating vs. Continuous Exposure to H2O2: The Effects on Mitochondrial Membrane Potential, Intracellular Calcium, and NF-kappa B in Astroglia
(Public Library Science, San Francisco, 2013)
The effects of H2O2 are widely studied in cell cultures and other in vitro systems. However, such investigations are performed with the assumption that H2O2 concentration is constant, which may not properly reflect in vivo ...
Improving reactivity of fly ash and properties of ensuing geopolymers through mechanical activation
(Elsevier Sci Ltd, Oxford, 2014)
This paper investigated the effects of mechanical activation of fly ash (FA) from thermal power plants on physical-mechanical properties and structure of geopolymers. FA from different power plants in Serbia was mechanically ...
Demographic flexibility influences colonization success: profiling invasive fish species in the Danube River by the use of population models
(Springer, Dordrecht, 2015)
Invasive species have the ability to modify their life-history traits in newly colonized areas, with positive shifts in specific life history traits under favourable environmental conditions. If such positive changes in ...
Contrasting effect of silicon on iron, zinc and manganese status and accumulation of metal-mobilizing compounds in micronutrient-deficient cucumber
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2014)
Although the beneficial role of silicon (Si) in alleviation of abiotic stress is well established, little is known of the relevance of Si nutrition under microelement deficiency. The aim of our work was to investigate the ...
Raman Responses in Mechanically Activated BaTiO3
(Wiley, Hoboken, 2014)
The structure and lattice dynamics of mechanically activated BaTiO3 was investigated in this study. Phonon behavior and crystal structure stability of the obtained nanocrystalline BaTiO3 were discussed from the view point ...
Seasonal variation in element concentrations in surface sediments of three rivers with different pollution input in Serbia
(Springer Heidelberg, Heidelberg, 2016)
The main objective of this study was to evaluate the concentrations and seasonal variations of trace elements in surface sediments of three major rivers in Serbia-the Danube, the Zapadna Morava (ZM), and the JuA3/4na Morava ...
Surface tip-to-base Ca2+ and H+ ionic fluxes are involved in apical growth and graviperception of the Phycomyces stage I sporangiophore
(Springer, New York, 2012)
Net fluxes of Ca2+ and H+ ions were measured non-invasively close to the surface of Phycomyces blakesleeanus sporangiophores stage I using ion-selective vibrating microelectrodes. The measurements were performed on a wild ...
Profiling antioxidant activity of two primocane fruiting red raspberry cultivars (Autumn bliss and Polka)
(Academic Press Inc Elsevier Science, San Diego, 2013)
Fruit extracts of two raspberry (Rubus idaeus L) cultivars (Autumn Bliss and Polka) were analysed for total phenolic (TPC) and anthocyanin (TACY) content. Correlation of TPC with total antioxidant capacity (TAC) showed ...
Improvement of barium titanate properties induced by attrition milling
(Elsevier Sci Ltd, Oxford, 2012)
Barium titanate powder was prepared by soft chemical process from polymeric precursors (modified Pechini process). The synthesized barium titanate (BT) powder was nanosized and the factor of agglomeration (F-agg) pointed ...
Redox therapy in neonatal sepsis: reasons, targets, strategy, and agents
(Lippincott Williams & Wilkins, Philadelphia, 2014)
Neonatal sepsis is one of the most fulminating conditions in neonatal intensive care units. Antipathogen and supportive care are administered routinely, but do not deliver satisfactory results. In addition, the efforts to ...
