Antioxidant properties of grape seed extract on human lymphocyte oxidative defence
(Georg Thieme Verlag Kg, Stuttgart, 2008)
The distribution of polyphenolic compounds in a grape (Vitis vinifera) seed extract (GSE) was determined using LC/ESI-TOF MS, HPLC/DAD, and C-13-NMR. The 17 identified compounds comprised gallic and protocatechuic acid, ...
Ethyl 3-(6-phenyl-44-1,2-dithiolo[1,5-b][1,2,4]dithiazol-2-yl) propanoate
(International Union of Crystallography, 2008)
The title compound, C15H15NO2S3, exists in a bicyclic form, with resonance contributions from two monocyclic forms, each without a second S - S bond. The trithiapentalene heterocyclic ring system is planar, with a mean ...
Process improvement approach to the acid activation of smectite using factorial and orthogonal central composite design methods / Faktorijalni i ortogonalno centralno kompozitni plan eksperimenta kiselinske aktivacije smektita
(Serbian Chemical Society, 2008)
The purpose of this study was to determine the effective operating parameters and the optimum operating conditions of an acid activation process within the framework of improvement of the process. Full two-level factorial ...
Chemical stability of the peroxide bond enables diversified synthesis of potent tetraoxane antimalarials
(American Chemical Society (ACS), 2008)
Of 17 prepared 1,2,4,5-tetraoxacyclohexanes stable to reductive and acidic conditions, 3 of them were more active than artemisinin against CQ and MFQ resistant strain TM91C235 and all compounds were more active in vitro ...
Surface Texture Parameters in Optimizing Magnetic Force Images
(Belgrade : Astronomical Observatory, 2008)
In this work, the optimizing conditions necessary for magnetic field gradient imaging using Atomic Force Microscopy (AFM) and Magnetic Force Microscopy (MFM) in a lift mode have been established. 55 nm thick Co thin film ...
Multifractal analysis of the UV/VIS spectra of malignant ascites: Confirmation of the diagnostic validity of a clinically evaluated spectral analysis
(Physica A: Statistical Mechanics and its Applications, 2008)
Multifractal (MF) approach was applied for the analysis of ultraviolet/visible (UV/VIS) spectra as an independent confirmation of the diagnostic efficacy of UV/VIS spectral analysis of intraperitoneal fluids, ascites, taken ...
Metal-dielectric photonic crystal for the enhancement of solar-blind ultraviolet silicon photodiodes
(Institute of Electrical and Electronics Engineers Inc., 2008)
We report the fabrication of metal-dielectric photonic crystals as bandpass filter for the UV riadiation with a sidelobe suppression in excess of 4 orders of magnitude. The metal-dielectrics were designed for the enhcancement ...
Stereochemistry and conformations of natural 1,2-epoxy-guaianolides based on 1D and 2D NMR data and semiempirical calculations
(Magnetic Resonance in Chemistry, 2008)
From detailed study of ID and 2D NMR spectra of ten natural 1,2-epoxyguaianolides (bis-1,2:3,4-epoxyguaianolides and guaianolide-1,2- epoxychlorohydrins), we identified general spectral traits helpful for stereochemical ...
Lipids and cholesterol content in pigs' neck and the activity of glutathione-dependent enzymes / Sadržaj masti i holesterola u vratu svinja i aktivnost glutation zavisnih enzima
(Tehnologija mesa, 2008)
Pigs' neck meat is predominantly used for barbecues. In order to prevent oxysterols formation during thermal preparation, it is important to be aware of the content of fats, cholesterol and the activity of lipid peroxide ...
Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus ferrooxidans - Research on a model system
(Elsevier, 2008)
Oil shale is one of the alternative sources of hydrocarbon fuels ("synthetic petroleum") but is characterized by increased sulfur and nitrogen contents, which represent even greater ecological problems in its use compared ...
