Spectrophotometric and electrochemical study of protolytic equilibria of some oximes-acetylcholinesterase reactivators
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Newly synthesized oximes, mono and bis imidazole derivatives, which promise to be more effective acetylcholinesterase reactivators than standard antidotes used, were investigated by spectrophotometric and electrochemical ...
Simple and rapid method for the measurement of nitrite and nitrate in human plasma and cerebrospinal fluid by capillary electrophoresis
(Elsevier Science BV, Amsterdam, 1999)
Nitrite and nitrate levels in physiological fluids are commonly used as an index of nitric oxide production. We developed simple and rapid method for the determination of these anions by capillary zone electrophoresis ...
Determination of some insect repellents in cosmetic products by high-performance thin-layer chromatography
(Elsevier Science BV, Amsterdam, 1999)
A simple and reliable thin-layer chromatographic method for the determination of N,N-diethyl-m-toluamide (DEET) and dimethyl phthalate (DMP) in raw material and cosmetic products was developed and validated. A benzene-diethyl ...
The role of transforming growth factor-beta in identifying patients with coronary artery disease
(Društvo medicinskih biohemičara Srbije i Crne Gore, Beograd i Univerzitet u Beogradu - Farmaceutski fakultet, Beograd, 1999)
Transforming growth factor-beta (TGF-beta) is a cytokine with antiatherogenic propretis. The active form of TGF-beta inhibits the activation of endothelial cells, and acts on vascular smooth muscle cells by inhibiting their ...
The influence of ethanol addition on excitation of aluminium in the argon stabilized d.c. arc
(Akademiai Kiado, Budapest, 1999)
The effect of ethanol addition on the spectral line intensities of aluminium and excitation conditions in an argon stabilized d.c. are was investigated. In order to find optimal conditions for trace elements determination, ...
Identification of protonic species and their dynamic equilibrium in magnesium and calcium salts of 12-tungstophosphoric acid
(Elsevier Science BV, Amsterdam, 1999)
This contribution presents the results of the investigation of Mg2+ and Ca2+ 12-tungstophosphoric acid (WPA) salts as superionic proton conductors. We have identified protonic species as charge carriers in several hydration ...
Spectrophotometric investigation of the Cu(II)-hesperidin complex
(Govi-Verlag Gmbh, Eschborn, 1999)
A taraxasterol derivative and phenolic compounds from Hieracium gymnocephalum
(Elsevier Ltd, 1999)
From the aerial parts of Hieracium gymnocephalum the new triterpene, 21α-hydroxy-taraxasterol and flavone diglycosides luteolin 7-O-α-L- rhamnosyl(1 → 6)-β-D-glucoside and luteolin 7-O-β-D-xylosyl(1 → 6)-β-D- glucoside ...
Aromatic Plants of Yugoslavia. I. Chemical Composition of Oils of Achillea millefolium L. ssp. pannonica (Scheele) Hayak, A. crithmifolia W. et K., A. serbica Nym. and A. tanacetifolia All.
(Allured Publishing Corp., 1999)
We used GC/MS to determine the chemical composition of the essential oils of
wild Achillea plants native to Yugoslavia: Achillea millefolium L. ssp. pannonica
(Scheele) Hayak, A. crithmifolta W. et K., A. serbica Nym. ...
Flavonoid and phenolic acid patterns in seven Hieracium species
(Biochemical Systematics and Ecology, 1999)
We propose a new model for landslide dynamics under the assumption of a delay failure mechanism. Delay failure is simulated as a delayed interaction between adjacent blocks, which mimics the relationship between the ...
