  1. 1. Partitioning of Drugs and Lignin Precursor Models into Artificial Membranes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elisabet Boija; Uppsala universitet.; [2006]
    Keywords : Biochemistry; Bilayer disk; Capillary electrophoresis; Detergent; Drug; Electrostatic interaction; Hydrophobic interaction; Immobilized liposome chromatography; Lignin; Lignin precursor model; Liposome; Membrane model; Octanol water partitioning; Partitioning; Phospholipid; Phospholipid bilayer; Sterol; Biokemi;

    Abstract : The main aim of this thesis was to characterize membrane-solute interactions using artificial membranes in immobilized liposome chromatography or capillary electrophoresis. The partitioning of a solute into a cell membrane is an essential step in diffusion across the membrane. READ MORE

  2. 2. 13C-Enriched Dehydrogenation Polymers Used for Studying Light-Induced Yellowing of Lignocellulosic Materials

    University dissertation from Chalmers University of Technology

    Author : Jim Parkås; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; spruce; Picea abies; differentiating xylem; DHP; lignin; 13C-enrichment; 13C NMR spectroscopy; solid state; yellowing; lignin model compounds;

    Abstract : This study deals with the use of selectively 13C-enriched dehydrogenation polymers (DHPs) as models of lignin in lignocellulosic materials for elucidating the reaction pathways involved in light-induced yellowing. Methods for the synthesis of coniferin, a precursor to lignin and DHP, selectively 13C-enriched in the aromatic ring (positions 1, 3, 4, and 5) have been developed. READ MORE

  3. 3. A study of the traits associated with the biocontrol activity of Phlebiopsis gigantea

    University dissertation from Chalmers University of Technology

    Author : Anthony Christian Mgbeahuruike; Sveriges lantbruksuniversitet.; [2009]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Phlebiopsis gigantea has routinely been used for the biocontrol of the conifer pathogen, Heterobasidion annosum s.l. but the mechanism for the biocontrol action has not been properly understood. In the present work, 64 isolates of P. READ MORE
