  1. 1. Characterization of two novel fatty acid dioxygenases : Linoleate diol synthase and manganese lipoxygenase

    Author : Chao Su; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Dioxygenase; hemeprotein; lipoxygenase; metalloenzyme; oxylipin; fatty acid; manganese-protein; Gaeumannomyces graminis; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Two classes of fatty acid dioxygenases, PGH synthases (hemeproteins) and lipoxygenases (non-heme iron proteins), are of eminent pharmacological importance. This thesis describes a PGH synthase-related dioxygenase designated linoleate diol synthase (LDS) and the first native occurring manganese-containing lipoxygenase. READ MORE

  2. 2. Expression of Manganese Lipoxygenase and Site-Directed Mutagenesis of Catalytically Important Amino Acids : Studies on Fatty Acid Dioxygenases

    Author : Mirela Cristea; Ernst H. Oliw; Chao Su; Olof Rådmark; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Dioxygenase; Gaeumannomyces graminis; lipoxygenase; Magnaporthe grisea; oxylipin; Pichia pastoris; hydroperoxide isomerase; polyunsaturated fatty acids; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Abstract : Polyunsaturated fatty acids can be bioactivated by two families of dioxygenases, which either contain non-heme iron (lipoxygenases) or heme (cyclooxygenases, linoleate diol synthases and α-dioxygenases).Lipoxygenases and their products play important roles in the pathophysiology of plants and fungi.

  3. 3. Imine/azo-linked microporous organic polymers : Design, synthesis and applications

    Author : Chao Xu; Niklas Hedin; Dave Adams; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microporous organic polymers; CO2 capture and separation; post-modification; chemisorption; heterogeneous catalysis; materialkemi; Materials Chemistry;

    Abstract : Microporous organic polymers (MOPs) are porous materials. Owing to their high surface area, tunable pore sizes and high physicochemical stability, they are studied for applications including gas capture and separation and heterogeneous catalysis. In this thesis, a series of imine/azo-linked MOPs were synthesized. READ MORE

  4. 4. Group-Theoretical Structure in Multispectral Color and Image Databases

    Author : Thanh Hai Bui; Reiner Lenz; Björn Kruse; Jinhui Chao; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group theory; PCA Principal Component Analysis ; CBIR; Content-based Image Retrieval ; filter; color; image; multispectral; database; Signal processing; Signalbehandling;

    Abstract : Many applications lead to signals with nonnegative function values. Understanding the structure of the spaces of nonnegative signals is therefore of interest in many different areas. Hence, constructing effective representation spaces with suitable metrics and natural transformations is an important research topic. READ MORE

  5. 5. A multi-faceted approach to a "dark taxon" : The hyperdiverse and poorly known scuttle flies (Diptera: Phoridae)

    Author : Emily Hartop; Fredrik Ronquist; Torbjørn Ekrem; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; taxonomy; dark taxa; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Most of the unknown animal biodiversity on earth is in groups of invertebrates that are hyperdiverse and abundant, yet poorly known (“dark taxa”). The study of these organisms requires a multi-faceted approach and methodologies designed to tackle large numbers of species and specimens. READ MORE
