  1. 1. Theory of water-proton spin relaxation in complex biological systems

    Författare :Zhiwei Chang; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin relaxation theory; immobilized macromolecules; magnetic relaxation dispersion; integral longitudinal relaxation rate; stochastic Liouville equations; multi-spin systems; cross-mode relaxation; spectral density functions;

    Sammanfattning : In complex biological systems (e.g. gels, cross-linked proteins and biological tissues), the longitudinal spin relaxation of water protons is primarily induced by exchange-mediated orientational randomization (EMOR) of intra- and intermolecular magnetic dipole-dipole couplings.

  3. 2. Water and Protein Dynamics in Biological Systems Studied by Magnetic Relaxation Dispersion

    Författare :Erik Persson Sunde; Biofysikalisk kemi; []
    Nyckelord :protein dynamics; ubiquitin; BPTI; Escherichia coli; Haloarcula marismortui; nuclear magnetic resonance; protein hydration; magnetic relaxation dispersion; water dynamics; cell water;

    Sammanfattning : The results presented in this thesis demonstrate that the magnetic relaxation dispersion (MRD) technique can provide information of relevance to protein biophysics, magnetic resonance imaging and cell biology. By immobilizing proteins with covalent cross-links, intermittent protein dynamics on the previously inaccessible ns-µs time scale could be probed with MRD via the exchange of water molecules between internal cavities and the surrounding bulk solvent phase.

  4. 3. Functional ecology of ectomycorrhizal fungi : peroxidases, decomposition, spatial community patterns

    Författare :Inga Bödeker; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Boreal forest ecosystems constitute a globally important carbon (C) sink, due to accumulation of complex organic matter, persistent to decomposition. Nitrogen (N) is immobilized in these complex compounds and, thereby, unavailable to the plant community. LÄS MER

  5. 4. Cryogels as Solid Supports in Bioprocessing

    Författare :Gry Jespersen; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Downstream processing; cryogel; solid support; biomacromolecules; chromatography;

    Sammanfattning : In recent years the market for biopharmaceutical products has been increasing rapidly as a result of an increased demand for new and efficient treatments of various indications. Biopharmaceuticals are distinguished from chemical drugs by being derived from a biological origin and are hence, frequently constituting biological macromolecules. LÄS MER

  7. 5. Molecularly Imprinted Polymer Beads-Synthesis, Evaluation and Applications

    Författare :Tongchang Zhou; Tillämpad biokemi; []
    Nyckelord :Molecularly imprinted polymer beads; Pickering emulsion; RAFT; water-compatible;

    Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial receptors designed for the selective recognition of template molecules. These polymers have been applied in analytical separations, as chemical sensors and in drug delivery system due to their low cost and high stability. LÄS MER
