Immobilization of glucoamylase via its carbohydrate moiety on macroporous poly(GMA-co-EGDMA)
(Elsevier, 2007)
We succeeded in the immobilization of 190 mg of periodate oxidized glucoamylase per gram of macroporous polymer. The covalently immobilized enzyme had a specific activity of 1100 U/g. The temperature and pH optimum as well ...
Performance limits to the operation of nanoplasmonic chemical sensors: noise-equivalent refractive index and detectivity
(Spie-Soc Photo-Optical Instrumentation Engineers, Bellingham, 2009)
We considered figures of merit for chemical and biological sensors based on plasmonic structures and utilizing adsorption/desorption mechanism. The operation of these devices in general is limited by noise determining the ...
Synthesis, characterization and crystal structure of palladium(II) complexes containing edta tetraalkyl ester ligands
(Ceska Republika : Akademie Ved Ceske Republiky, 2007)
The reaction of solutions of tetraalkyl ethylenediamine-N,N,N′, N′-tetraacetate esters (alkyl = Me, 1a; Et, 1b) with H 2[PdCl4] led to the complexes [PdCl2(R 4EDTA)] (R = Me, 2a; Et, 2b). The coordination of R4EDTA ligands ...
Silver–silica transparent metal structures as bandpass filters for the ultraviolet range
(IOP Publishing, 2005)
We designed and produced silver–silicon dioxide multilayer thin-film bandpass filters for the ultraviolet range by applying the concept of 'transparent metals'. To calculate the transmission of the designed metallodielectric ...
Effect of pH and human serum albumin on the cytotoxicity of a glucuronide prodrug of 9-aminocamptothecin
(Switzerland : Springer Nature, 2007)
Purpose: 9-aminocamptothecin glucuronide (9ACG) is a prodrug of 9-aminocamptothecin (9AC) that displays potent antitumor activity against human tumor xenografts in nude mice. Camptothecins exist in a pH dependent equilibrium ...
Multifractal analysis of the UV/VIS spectra of malignant ascites: Confirmation of the diagnostic validity of a clinically evaluated spectral analysis
(Physica A: Statistical Mechanics and its Applications, 2008)
Multifractal (MF) approach was applied for the analysis of ultraviolet/visible (UV/VIS) spectra as an independent confirmation of the diagnostic efficacy of UV/VIS spectral analysis of intraperitoneal fluids, ascites, taken ...
Oxidation of n-hexane over Pt and Cu-Co oxide catalysts supported on a thin-film zirconia/stainless steel carrier
(Catalysis Communications, 2008)
The complete oxidation of n-hexane in air over a stainless steel foil (SS) coated with a thin film of ZrO2 (SS/ZrO2), SS/ZrO2/Pt, SS/ZrO2/La2O3/CuCo and SS/ZrO2/La2O3/CuCo/Pt catalysts has been investigated. The ZrO2 films ...
Stereochemistry and conformations of natural 1,2-epoxy-guaianolides based on 1D and 2D NMR data and semiempirical calculations
(Magnetic Resonance in Chemistry, 2008)
From detailed study of ID and 2D NMR spectra of ten natural 1,2-epoxyguaianolides (bis-1,2:3,4-epoxyguaianolides and guaianolide-1,2- epoxychlorohydrins), we identified general spectral traits helpful for stereochemical ...
Cholesterol bound to hemoglobin in normal human erythrocytes: a new form of cholesterol in circulation?
(Elsevier, 2004)
Objective: To study lipid fraction that is occasionally observed in red blood cell (RBC) hemolysate (supernatants from which membranes were separated). Study design: Plasma lipid profiles, cholesterol (Ch) and phospholipids ...
Reactions of ortho-substituted α,α-dibromoacetophenones with nucleophiles: first examples of combined carbophilic and bromophilic attack on C-Br bonds
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
An efficient method for the formation of α-carbonyl-monosubstituted acetophenones from ortho-methoxy- and ortho-hydroxy-α,α-dibromoacetophenones and a range of selected nucleophiles, occurring via a carbophilic ...
