Optimization of the RP-HPLC method for multicomponent analgetic drug determination.
(Bollettino chimico farmaceutico, 2003)
The optimization of RP-HPLC method defined the simultaneous influence of some important conditions, such as the mobile phase composition, pH of the mobile phase and temperature, on the separation and determination. The ...
Apoptotic versus genotoxic potential of antiotumor agents: a concept of duality in unity (vol 61, pg 131, 2003)
(Churchill Livingstone, Edinburgh, 2003)
Study of the lipophilicity and retention behavior of some beta-adrenoceptor antagonists
(Springer Nature, 2003)
The chromatographic behavior of some beta-adrenoceptor antagonists has been studied by RP HPTLC on C-18 with water-acetonitrile (phi = 0.2-0.7) and water-dioxane (phi = 0.1-0.5) mobile phases. The retention mechanism was ...
Artificial neural networks in the modeling and optimization of aspirin extended release tablets with Eudragit L 100 as matrix substance
(AAPS PharmSci Editorial Office, 2003)
The purpose of the present study was to model the effects of the concentration of Eudragit L 100 and compression pressure as the most important process and formulation variables on the in vitro release profile of aspirin ...
Trace elements analysis of Echinacea purpurea - herbal medicinal
(Elsevier Science BV, Amsterdam, 2003)
Elemental composition of Echinacea purpurea (Asteracae), grown in Serbia under strongly controlled conditions, has been studied. To distinguish elemental patterns of different parts of the plant, the content of Zn, Fe, Cu, ...
Evaluation of Tanacetum larvatum for an anti-inflammatory activity and for the protection against indomethacin-induced ulcerogenesis in rats
(Elsevier Ireland Ltd, Clare, 2003)
Oral administration of the chloroform extract from Tanacetum larvatum (Griseb. ex Pant.) Kanitz caused a dose-dependent anti-inflammatory effect in the carrageenan-induced rat paw oedema test. The obtained anti-inflammatory ...
Photochemical degradation of solid-state nisoldipine monitored by HPLC
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The photochemical degradation of solid-state nisoldipine, 1,4-dihydropyridine calcium antagonist, was investigated under daylight and UV light conditions. Degradation products were identified by using the retention times ...

Influence of sodium dodecyl sulfate on the kinetics of complex formation between [PdCl(dien)](+) and sulfur containing ligands L-cysteine and glutathione
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The effect of sodium dodecyl sulfate (SDS) micelles on the kinetics of the complex formation between [PdCl(dien)](+) and sulfur containing ligands L-cysteine and glutathione (GSH) was investigated by using the stopped-flow ...
Preliminary assay on the antioxidative activity of Maydis stigma extracts
(Elsevier Science BV, Amsterdam, 2003)
Antioxidative effects of Maydis stigma methanolic extracts were studied on the level of lipid peroxidation in liposomes, induced by Fe2+/ascorbate system and measured spectrophotometrically by the TBA-test. The most ...
