Distribution and fractionation of heavy metals in the Tisa (Tisza) River sediments
(Springer Heidelberg, Heidelberg, 2007)
Introduction. In this work, sediments of the River Tisa (Tisza) are studied to assess their environmental pollution levels for some major heavy metals, as well as to predict the investigated elements' mobility on the basis ...
The qualitative electrochemical determination of clarithromycin and spectroscopic detection of its structural changes at gold electrode
(Elsevier, 2007)
The aim of the present study was the qualitative determination of the pure clarithromycin using a gold electrode in neutral electrolyte by cyclic linear sweep voltammetry. It was shown that in the range of -1.2 V to 1.0 V ...
Far infrared properties of PbTe doped with cerium
(Elsevier, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300 K are presented. The experimental data were numerically ...
Porosity of different dental luting cements
(Elsevier, 2007)
Objective. The aim of this in vitro study was to compare open porosity and pore size distribution
of different types of luting cements (zinc phosphate and polycarboxylate produced by
Harvard Cement, Great Britain, ...
Organocatalyzed cyclizations of π-allylpalladium complexes: A new method for the construction of five- and six-membered rings
(American Chemical Society (ACS), 2007)
Synergic combination of organotransition metal catalysis and organocatalysis allows, for the first time, the Tsuji-Trost cyclization of aldehydes. A catalytic asymmetric variant of the reaction is also possible.
Are Chelate Rings Aromatic? Calculations of Magnetic Properties of Acetylacetonato and o-Benzoquinonediimine Chelate Rings
(American Chemical Society (ACS), 2007)
The aromaticity of the chelate rings of acetylacetonato (acac) and o-benzoquinonediimine (bqdi) ligands was
investigated theoretically by calculating nucleus-independent chemical shifts (NICS). The calculations were ...
Kinetics and mechanism of the formation of poly[(1,1,3,3- tetramethyldisiloxanyl)ethylene] and poly(methyldecylsiloxane) by hydrosilylation
(Wiley-Blackwell, 2007)
The kinetics of the formation of poly(carbosiloxane), as well as of alkylsubstituted poly(siloxane), by Karstedt's catalyst catalyzed hydrosilylation were investigated. Linear poly(carbosiloxane), poly[(1,1,3,3-tetrameth ...
A refined pharmacophore identifies potent 4-amino-7-chloroquinoline-based inhibitors of the botulinum neurotoxin serotype A metalloprotease
(American Chemical Society (ACS), 2007)
We previously identified structurally diverse small molecule (non-peptidic) inhibitors (SMNPIs) of the botulinum neurotoxin serotype A (BoNT/A) light chain (LC). Of these, several (including antimalarial drugs) contained ...
Influence of thermal treatment on phenolic compounds and antioxidant properties of oak acorns from Serbia
(Elsevier, 2007)
The aim of the present work was to investigate and compare phenolic compounds and antioxidant activity of methanol extracts of Quercus robur and Quercus cerris acorn kernels obtained before and after thermal treatment. ...
Deoxycholic acid-derived tetraoxane antimalarials and antiproliferatives
(American Chemical Society (ACS), 2007)
The synthesis of deoxycholic acid (DCA)- and cholic acid (CA)-derived mixed tetraoxanes revealed that N-(2-dimethylamino)ethyl derivatives are potent antimalarials in vitro and in vivo. The tetraoxanes presented in this ...
