Voltammetric and Square-Wave Anodic Stripping Determination of Amlodipine Besylate on Gold Electrode
(Electrochemical Science Group, Beograd, 2012)
The oxidative behaviour of amlodipine besylate was studied. The gold electrode and Au/o-MWCNT (oxidized multi-wall carbon nanotubes) were used for determination of amlodipine besylate standard and as a content of Alopres ...
Synthesis of Barium-zinc-titanate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
In vitro investigation of the antihypertensive effect of the moss rhodobryum ontariense (kindb.) (kindb.)
(Inst Materials Physics, 2012)
The ability to modulate erythrocyte membrane fluidity, the capacity to release nitric oxide and the ABTS [2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid)] cation scavenging activity including the total phenolic ...
Sugars and acid invertase mediate the physiological response of Schenkia spicata root cultures to salt stress
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2012)
A heterotrophic model system was established in our studies in order to differentiate the effect of high salt concentrations in external medium on growth and sugar metabolism in roots from the effect of reduced sugar ...
In vitro evaluation of the immunomodulatory and anticarcinogenic activity of the freshwater bryozoan hyalinella punctata methanolic extract
(Inst Materials Physics, 2012)
The immunomodulatory and anticarcinogenic activity of the freshwater bryozoan Hyalinella punctata methanolic extract (MEx) was evaluated in vitro on selected biosystems for the first time. Murine lymphocytes and macrophages ...
Formation of the honeycomb-like electrodes by the regime of pulsating overpotential in the second range
(International Association of Physical Chemists, 2012)
In this study the honeycomb-like copper structures electrodeposited by the regime of pulsating overpotential in the second range were analyzed by the technique of scanning electron microscopy. The overpotential amplitude ...
Antimicrobial activity of the freshwater bryozoan hyalinella punctata (Hancock, 1850)
(Inst Materials Physics, 2012)
The antimicrobial activity of the freshwater bryozoan Hyalinella punctata (Hancock, 1850) was tested by microdilution method against eight bacteria and eight fungi for the first time. All five crude extracts (hexane, ...
Silicon ameliorates manganese toxicity in cucumber by decreasing hydroxyl radical accumulation in the leaf apoplast
(Oxford Univ Press, Oxford, 2012)
This work was focused on the role of silicon (Si) in amelioration of manganese (Mn) toxicity caused by elevated production of hydroxyl radicals (center dot OH) in the leaf apoplast of cucumber (Cucumis sativus L.). The ...
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 ...
On the kinetics of the hydrogen evolution reaction on Ni-MoOx composite catalysts in alkaline solutions
(Srpsko hemijsko društvo, Beograd, 2012)
MoO3 particles were co-deposited with Ni onto smooth or rough Ni supports from modified Watt baths of different compositions. Morphology and composition of the electrodeposits were characterized by means of cyclic voltammetry, ...
