Screening of selenium absorption ability of mycelia of selected Pleurotus species
(Teknoscienze Publ, Milan, 2006)
Pleurotus species are economically high praised due to their edible and medicinal properties. Selenium is a trace element with antioxidant and anticarcinogenic effects. The aim of our research was to investigate the influence ...
Improved procedure for the preparation of cis-2,4-dimethylglutaranhydride
(Taylor & Francis Inc, Philadelphia, 2006)
Addition of 2.5 mol% DBU to a mixture of isomeric 2,4-dimethylglutaric anhydrides in ethyl acetate promotes crystallization-induced transformation, affording the pure cis-2,4-dimethylglutaric anhydride in 87% yield.
Liquid-crystalline bisadducts of [60]fullerene
(Amer Chemical Soc, Washington, 2006)
A second-generation cyanobiphenyl-based dendrimer was used as a liquid-crystalline promoter to synthesize mesomorphic bisadducts of [60]fullerene. Liquid-crystalline trans-2, trans-3, and equatorial bisadducts were obtained ...
A dendritic fullerene-porphyrin dyad
(Royal Soc Chemistry, Cambridge, 2006)
We describe the synthesis, characterization and photophysical properties of a fullerene derivative whose structure includes a Zn-porphyrin and a second generation liquid-crystalline (LC) dendrimer. The size of the fullerene ...
Allosteric regulation of the conformational dynamics of a cavitand receptor
(Amer Chemical Soc, Washington, 2006)
Inspired by allostery in nature, we synthesized cavitand 1 and investigated regulation of its conformational dynamics. Quantitative H-1 NMR studies have revealed that the rate of the conformational isomerization of 1 can ...
Activity and stability of soluble and immobilized alpha-glucosidase from baker's yeast in cosolvent systems
(Taylor & Francis Ltd, Abingdon, 2006)
The activity of alpha-glucosidase from baker's yeast was determined in various concentrations of dioxan, tetrahydrofuran, tert-butanol, dimethylformamide, methanol and dimethylsulfoxide (DMSO). Higher activities were ...
Conformational analysis of edta-type rhodium(III) complexes with mixed five- and six-membered chelate rings. Structural analysis of conformational flexibility in rhodium(III) complexes containing 1,3-propanediamine-N,N′-diacetate-N,N′-di-3-propionate liga
(Journal of Molecular Structure, 2006)
Conformational analysis of the three possible geometrical isomers: trans(O5), trans(O5O6) and trans(O6) of the sexidentate [Rh(1,3-pddadp)]- complex, and of the 10 possible isomers: four cis-equatorial, four cis-polar and ...
Cholinesterase inhibition based determination of pancuronium bromide in biological samples
(Springer Heidelberg, Heidelberg, 2006)
Pancuronium bromide (PCBr) inhibition effect on enzyme cholinesterase from pooled human serum (Che, EC 3.1.1.8 acylcholine acylhydrolase) was used for development of a spectrophotometric kinetic method for PCBr determination ...
Petroleum pollutant degradation by surface water microorganisms
(Ecomed Publishers, Landsberg, 2006)
Background, Aims and Scope. It is well known that the composition of petroleum or some of its processing products changes in the environment mostly under the influence of microorganisms. A series of experiments was conducted ...
