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 effects of selenium deficiency, dietary selenium, and vitamin E supplementation on the oxidative status of pig liver
(Begell House Inc., 1998)
The aim of this work was to determine the effect of Selenium (Se) deficiency on the porcine liver oxidative stability and to investigate Se content and oxidative status in porcine liver after dietary supplementation with ...
Kinetic Determination of Trace Levels of Selenium(IV) and Total Selenium by Nile Blue A/Hydrogen Peroxide Method
(Springer New York, 1998)
A kinetic method for the determination of selenium(IV) traces is proposed, based on its inhibitory action on the oxidation of Nile Blue A by hydrogen peroxide in phosphate buffer (pH 10.5). A linear dependence was established ...
Furo- and pyranocoumarins from plant species Angelica silvestris and Peucedanum austriacum
(Journal of the Serbian Chemical Society, 1993)
An investigation of the coumarin content of plant species Angelica silvestris (roots and fruits) and Peucedanum austriacum (Jacq.) Koch (roots), both belonging to the family Apiaceae is reported. A. silvestris contained ...
Contribution to interaction between magnesium and toxic metals: The effect of prolonged cadmium intoxication on magnesium metabolism in rabbits
(John Libbey Eurotext, 1998)
The results obtained up to now indicate that increased intake of some heavy metals causes disorder of bioelements metabolism leading to their blood and organs decrease and higher elimination via the urine. As to lead and ...
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, ...
