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 ...
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 ...
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 ...
High-yield synthesis of substituted and unsubstituted pyridinium salts containing a 4-oxothiazolidine moiety
(Georg Thieme Verlag Kg, Stuttgart, 2008)
A new series of unsubstituted and substituted pyridinium salts bearing a 4-oxothiazolidinyl moiety has been prepared by an efficient rearrangement of 2-(l-bromoalkylidene)thiazolidin-4-ones. The process is based on three ...
EPR spin-trapping and spin-probing spectroscopy in assessing antioxidant properties: Example on extracts of catkin, leaves, and spiny burs of castanea sativa
(Food Biophysics, 2009)
Electron paramagnetic resonance (EPR) spin-trapping and spin-probing techniques were applied to determine antioxidant activity of extracts of catkin, leaves, and spiny burs of Castanea sativa against physiologically relevant ...
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 ...
The effect of hydrogen co-deposition on the morphology of copper electrodeposits. II. Correlation between the properties of electrolytic solutions and the quantity of evolved hydrogen
(Elsevier, 2008)
Formation of irregular deposits by electrodeposition from acid sulfate solutions of various H2SO4 concentrations was examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
Synthesis, biological evaluation, and modeling of a C,D-seco-taxoid
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
A C,D-seco-paclitaxel derivative 12 was prepared and tested for biological activity. The key step in the synthesis was a free radical fragmentation of the bicyclic tertiary alcohol 7 under the conditions of the hypobromite ...
Synthesis, biology, and modeling of a C-4 carbonyl C,D-seco-taxoid
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
A C,D-seco-paclitaxel derivative 26 was prepared from taxine and tested for biological activity. Chemical reactivity of the seco-compounds proved to be substantially modified, with respects to taxoids. The corresponding ...
Antitumor effects of a natural anthracycline analog (Aloin) involve altered activity of antioxidant enzymes in HeLaS3 cells
(Taylor & Francis Inc, Philadelphia, 2007)
The anti proliferative and cytotoxic potential of the natural anthracycline aloin from Aloe vera was tested on human uterine carcinoma HeLaS3 cells. Aloin showed a pronounced antiproliferative effect at physiological ...
