(PERGAMON-ELSEVIER SCIENCE LTD, 2001-07)The polyamine, cadaverine, was detected in transformed root cultures of Brugmansia candida (syn. Datuira candida), a Solanaceae which produces the tropane alkaloids scopolamine and hyoscyamine. To the best of our knowledge, ...
-
(1991)Immunoaffinity chromatography involves binding of an antigen or antibody to a solid matrix, usually agarose, frequently using the cyanogen bromide method. These methods are laborious, rather expensive, and their use has ...
-
(ELSEVIER SCI LTD, 2008-07)The objective of this research was to study the kinetics of oil absorption and distribution in the structure of potato slices during frying, considering the effects of three oil temperatures and a blanching pre-treatment. ...
-
(1993)The concentration of the triterpene oleanolic acid in leaves of Baccharis linearis varies at different stages of plant growth from 1.9 to 3.0 g kg-1 fr. wt. Larvae of Heliothis zea, starved with 1.4 mg of oleanolic acid ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2009-09-02)Selective oxidation of galacturonic residues of oligo and polyuronic acids by Cr-VI affords CO2/HCO2H, oxidized uronic acid, and Cr-III as final redox products. Kinetic studies show that the redox reaction proceeds through ...
-
(MDPI, 2021)Gold nanoparticles (AuNPs) have been shown to be outstanding tools for drug delivery and biomedical applications, mainly owing to their colloidal stability, surface chemistry, and photothermal properties. The biocompatibility ...
-
(Institution of Chemical Engineers, 2017)Olive leaves extract (OLE) was microencapsulated with inulin (OLE-IN) by spray-drying using a central composite design. Oleuropein encapsulation efficiency and recovery values were over 87% in the OLE-IN microparticles ...
-
(2014)We show that the Gel’fand character χG of a finite group G (i.e. the sum of all irreducible complex characters of G ) may be realized as a “ twisted trace” g 7→ T r(ρg ◦ T ) for a suitable involutive linear automorphism ...
-
(Informa Healthcare, 1989)The characteristics of the visible luminescence that follows the lipid peroxidative process were investigated either in the autoxidation of rat brain homogenates or in the azo-bis-arnidinopropane initiated lipid peroxidation ...
