Cell wall invertase immobilization within calcium alginate beads
(Elsevier Sci Ltd, Oxford, 2007)
Yeast cell wall invertase (CWI) was immobilized within calcium alginate beads. The result of entrapment was the complete immobilization of all the added CWI. Three types of biocatalysts were prepared: CWI-S, CWI-155 and ...
Influence of thermal treatment on phenolic compounds and antioxidant properties of oak acorns from Serbia
(Elsevier Sci Ltd, Oxford, 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. ...
Are chelate rings aromatic? Calculations of magnetic properties of acetylacetonato and o-benzoquinonediimine chelate rings
(Amer Chemical Soc, Washington, 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 done ...
Synthesis and antioxidant properties of fullero-steroidal covalent conjugates
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Four new fullero-steroids were synthesized starting from gamma-aminobutyric acid (GABA)-incorporated fulleropyrrolidine and corresponding sterols. The synthesis, characterization, preliminary study on in vitro antioxidant ...
The dependence of cation distribution, microstrain and magnetic susceptibility on particle size in nanocrystalline Gd2O3/Y2O3
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
A novel synthesis route based on thermal decomposition of yttrium and gadolinium complexes with 2,4-pentanedione ligand has been used to synthesize 5 nn size (Y0.9Gd0.1)(2)O-3 powder. Refinement of occupancy parameters ...
A refined pharmacophore identifies potent 4-amino-7-chloroquinoline-based inhibitors of the botulinum neurotoxin serotype a metalloprotease
(Amer Chemical Soc, Washington, 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 ...
Silver(I) mediated folding of a molecular basket
(Amer Chemical Soc, Washington, 2007)
We have investigated Ag(I) mediated folding of a tridentate compound, containing three pyridine flaps tethered to a semirigid scaffold, into a molecular basket, using both experimental and theoretical methods. The basket ...
Investigation of nanocrystalline phases in Li-La-Fe-O system formed by the decomposition of acetylacetonato complexes
(Elsevier Science Sa, Lausanne, 2007)
Applying a new synthesis route based on the thermal decomposition of a mixture acetylacetonato complexes, Li(AA), La(AA)(3) and Fe(AA)(3), Li, La ferrite (Li0.5La0.08Fe2.42O4) was formed. The element analysis performed by ...
Distribution and fractionation of heavy metals in the Tisa (Tisza) River sediments
(Ecomed Publishers, Landsberg, 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 ...
