Manganese superoxide dismutase (MnSOD) catalyzes NO-dependent tyrosine residue nitration / Mangan-superoksid-dismutaza (MnSOD) katalizuje NO-zavisno nitrovanje ostatka tirozina
(Serbian Chemical Society, 2005)
The peroxynitrite-induced nitration of manganese superoxide dismutase (MnSOD) tyrosine residue, which causes enzyme inactivation, is well established. This led to suggestions that MnSOD nitration and inactivation in vivo, ...
Predictive modeling of the hypothalamic-pituitary-adrenal (HPA) function. dynamic systems theory approach by stoichiometric network analysis and quenching small amplitude oscillations
(International Journal of Nonlinear Sciences and Numerical Simulation, 2009)
Two methods for dynamic systems analysis, Stoichiometric Network Analysis (SNA) and Quenching of Small Amplitude Oscillations (QA), are used to study the behaviour of a vital biological system. Both methods use geometric ...
Evaluation of Hypericum perforatum oil extracts for an antiinflammatory and gastroprotective activity in rats
(Phytotherapy Research, 2009)
Oil extracts of Hypericum perforatum L. (Oleum Hyperici) were prepared in three different ways according to the prescriptions from traditional medicine. Variability of constituents and biological activity were evaluated ...
Composition of the essential oil of Ptilostemon gnaphaloides
(Springer, New York, 2008)
Micromechanical and structural properties of nickel coatings electrodeposited on two different substrates / Mikromehanička i strukturna svojstva elektrodeponovanih prevlaka nikla na različitim supstratima
(Serbian Chemical Society, 2009)
Fine-structured nickel coatings were electrodeposited from a sulfamate-based electrolyte onto different substrates: polycrystalline cold-rolled copper and single crystal silicon with (111) orientation. The influence of the ...
The Bray-Liebhafsky oscillatory reaction: Kinetic investigations in reduction and oxidation pathways based on hydrogen peroxide concentration monitoring
(International Institute for the Science of Sintering, Beograd, 2000)
By direct monitoring of the hydrogen concentration during its catalytic decomposition into water and oxygen in the presence of potassium iodate and sulfuric acid, that is in the Bray-Liebhafsky system, the pseudo-rate ...
Investigation of the conditions of synthesis of optical fiber-magnetic powder composites
(International Institute for the Science of Sintering, Beograd, 2000)
The goal of these investigations was synthesis of optical fiber-magnetic powder composites with new application possibilities like sensors, detectors etc. Parts of results of the investigation of the possibility of embedding ...
The influence of concentration of Nd-Fe-B powder in composite coating of optical fiber to the sensibility to external magnetic field
(Technical Faculty, Bor, 2005)
Multi-mode optical fiber with magnetic composite coating was investigated as an optical fiber sensor element (OFMSE) for magnetic field sensing The composite coating was formed with dispersions of permanent magnet powder ...
5,10:13,14-Disecosteroids: novel modified steroids containing 10- and 9-membered rings
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
In this paper a synthetic pathway to the modified 5,10:13,14-bisfragmentation cholestane derivatives 8-14 is described. The synthesis involves introduction of the 5α- and 14α-hydroxyl groups in the cholestane molecule and ...
Further guaianolides from Amphoricarpos neumayeri ssp murbeckii from Montenegro
(Verlag Z Naturforsch, Tubingen, 2006)
The aerial parts of Amphoricarpos neumayeri ssp. murbeckii afforded eleven guaianolides with the same relative (1 alpha H,4 beta H,5 alpha H, 7 alpha H) configuration of the basic skeleton. All of them contained a CH2OX ...
