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 ...
Determination of free bile acids in pharmaceuticals by thin layer cromatography and high performance liquid chromatography
(Lubner Communication Srl, 1998)
High-performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) and thin layer chromatography with flame ionization detection (TLC-FID) have been applied to the separation of five main free ...
Quantity and composition of essential oil of the wild plant Nepeta nuda L. from Yugoslavia
(Journal of Essential Oil Research, 1998)
The aerial parts of the wild plant Nepeta nuda L. collected in Serbia and the Durmitor region contained respectively 0.67–0.70% and 0.4% oil. Each oil was analyzed by GC and GC/MS. The main constituent was 1,8-cineole; ...
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 ...

Comparison of spectrophotometric and UV-densitometric methods for the determination of celiprolol hydrochloride in tablets
(Wiley, 1998)
Spectrophotometric and UV-densitometric methods for the determination of celiprolol hydrochloride in tablet formulations were compared. Celiprolol hydrochloride and benzylorange react in a 1:1 ratio in the presence of ...
Application of artificial neural networks in HPLC method development
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The use of artificial neural networks (ANNs) for response surface modelling in HPLC method development for amiloride and methychlothiazide separation is reported. The independent input variables were pH and methanol ...
Application of neural networks for response surface modeling in HPLC optimization
(Elsevier Science BV, Amsterdam, 1998)
The usefulness of artificial neural networks for response surface modeling in HPLC optimization is compared with multiple regression methods. The results show that neural networks offer promising possibilities in HPLC ...
