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 ...
First-order UV-derivative spectrophotometry in the analysis of omeprazole and pantoprazole sodium salt and corresponding impurities
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The first-order UV-derivative spectrophotometry, applying zero-crossing method was developed for the determination of omeprazole (OM), omeprazole sulphone (OMS), pantoprazole sodium salt (PANa), and N-methylpantoprazole ...
Determination of bifonazole in creams containing methyl- and propyl p-hydroxybenzoate by derivative spectrophotometric method
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
A second order derivative spectrophotometric method for the determination of bifonazole in the presence of methyland propyl p-hydroxybenzoate as preservatives has been developed. The determination was performed in a 0.1 M ...
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 ...
Salting-out thin-layer chromatography of several myorelaxants
(Research Inst Medicinal Plants, Budakalasz, 2003)
The chromatographic behavior of five myorelaxant drugs has been studied under the conditions used for salting-out thin-layer chromatography (SOTLC) on cellulose and alumina. For this purpose, aqueous ammonium sulfate ...
Circulating transforming growth factor-beta(1), lipoprotein(a) and cellular adhesion molecules in angiographically assessed coronary artery disease
(Walter de Gruyter & Co, Berlin, 2003)
Transforming growth factor-beta(1) (TGF-beta(1)) is involved in different physiological and pathological processes, including atherogenesis. High plasma lipoprotein(a) (Lp(a)) concentration is an established independent ...
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 ...
The essential oil composition of Salvia brachyodon Vandas
(John Wiley & Sons Ltd, W Sussex, 2003)
The essential oils of Salvia brachyodon (samples A and B), collected from Montenegro, were analysed by GC-MS. Fifty-four constituents were identified. The oil was characterized by a high content of oxygenated monoterpenes. ...
Visual-evoked potentials as additional diagnostic procedure in migraine headaches in childhood and adolescence
(International Congress Series, 2003)
Patients with migraine often show abnormalities in visual evoked potentials (VEP). The aim is to confirm diagnostic value of VEP in children and adolescents suffering from migraine and to compare findings with the control ...
