Methanol extracts of aerial flowering parts of four endemic Stachys taxa: S. anisochila Vis. et PANCIC, S. beckeana DORFLER & HAYEK, S. plumosa GRISEB. and S. alpina L. ssp. dinarica MURB. were investigated on their ...
High-spin binuclear Co(II) complexes with a pendant octaazamaclocycle and carboxylates / Visokospinski Co(II) kompleksi sa pendantnim oktaazamakrociklom i karboksilatima
(Srpsko hemijsko društvo, Beograd, 2007)
Three new binuclear Co(II) mixed-ligand complexes with N,N′,N′′,N′′′-tetrakis( 2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and mono- or dicarboxylate ligands were prepared and some of their physical properties ...
Acid-base equilibria of 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid and its labeling with technetium-99m / Kiselinsko-bazne ravnoteže 2,4-dijod-6-metilfenilkarbamoilmetil iminodisirćetne kiseline i obeležavanje tehnecijumom-99m
(Srpsko hemijsko društvo, Beograd, 2006)
The acid-base equilibria of a novel hepatobiliary imaging agent, 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid (DIIODIDA) were studied. The potentiometrically determined acidity constants of the second ...
Chromatographic behavior of fosinopril sodium and fosinoprilat using neural networks
(Springer Heidelberg, Heidelberg, 2008)
In this paper, the chromatographic characterization of fosinopril sodium and fosinoprilat is presented. The first stept was pK(a) determination for the active substance and its degradation product using RP-LC. It was ...
The second-derivative spectrophotometric assay of a multicomponent analgetic mixture
(Marcel Dekker Inc, New York, 2000)
In this paper the second-derivative spectrophotometric method for the simultaneous determination of some analgetic ingredients was described. Optimal conditions for the quantitative analysis of the three-component analgetic ...

Influence of ribavirin on the micronucleus formation and in vitro proliferation of human lymphocytes
(Slovak Academic Press Ltd, Bratislava, 2000)
Cytotoxic effects of the antiviremic drug ribavirin (1-beta -D-ribofuranosyl-1,2,4-triazole-3-carboxamide) were evaluated in vitro measuring micronucleus formation and cell proliferation kinetics in whole blood cultures ...
Preparation and characterisation of phenytoin-loaded alginate and alginate-chitosan microparticles
(Taylor & Francis Inc, Philadelphia, 2007)
We aimed to prepare and investigate microparticles with the varying contents of calcium gelling ion, loaded with phenytoin, a standard antiepileptic agent, in its acidic form. Two different methods of alginate-based ...
Antioxidative effect of nerve growth factor (NGF) in rat thalamus after quinolinic acid-induced neurotoxicity / Efekat NGF na antioksidativnu odbranu u talamusu pacova nakon neurotoksičnog delovanja hinolinske kiseline
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2003)
Quinolinic acid (QA) produces a pattern of selective cell loss in the striatum, that closely mimics that of Huntington's disease (HD). The aim of this study was to investigate the antioxidative status in the thalamus after ...
