  1. 1. Crystallographic studies on porphyrin metallation by ferrochelatase

    Författare :David Lecerof; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal and mechanical properties; Condensed matter:stucture; fasjämvikt; kristallografi; egenskaper termiska och mekaniska ; Kondenserade materiens egenskaper:struktur; crystallography; phase equilibria; Magnesium; pi-helix; Zinc; ferrochelatase; Metal binding; porphyrin metallation;

    Sammanfattning : Ferrochelatase catalyses the terminal step in heme biosynthesis by inserting a ferrous ion into protoporphyrin IX. The reaction mechanism has in this thesis been studied by mainly crystallographic methods. LÄS MER

  3. 2. Regulation of hematopoiesis by the Smad signaling pathway

    Författare :Ulrika Blank Savukinas; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; retroviral mediated gene expression; conditional knockout; hematopoietic stem cell; hematopoiesis; Transforming growth factor-beta; Smad signaling; Medicin människa och djur ;

    Sammanfattning : Hematopoietic stem cells (HSCs) reside in the bone marrow (BM) of adult individuals and are ultimately responsible for the continuous production of blood cells throughout life. The regulation of HSCs in vivo is tightly regulated by both intrinsic and extrinsic factors. LÄS MER

  4. 3. En liten sång som alla andra: Melodifestivalen 1959––1983 : A little song like all others: The Melody Festival 1959––1983

    Författare :Alf Björnberg; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Eurovision Song Contest; popular song; Sweden; musical style analysis; popular song lyrics; music and mass media; popular music and ideology;

    Sammanfattning : With the exception of three years, the Swedish Broadcasting Corporation has been a steady participant in the Eurovision Song Contest since 1958. Except for the first year, all Swedish entries have been selected by means of a televised national qualifying event. LÄS MER

  5. 4. Water and protein solutions studied by field-dependent magnetic relaxation

    Författare :Kristofer Modig; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relaxation; protein solvation; protein dynamics; protein denaturation; oxytocin; magnetic relaxation dispersion; nuclear magnetic resonance; lipid-binding protein; hydration; beta-lactoglobulin; BPTI; shielding anisotropy; water; Molecular biophysics; Molekylär biofysik;

    Sammanfattning : In the work presented, nuclear magnetic resonance (NMR) relaxation is used to study wide range of systems. The thesis concerns solvent interactions studied with relaxation techniques that involve measurements at many fields, which allows the separation of individual relaxation mechanisms. LÄS MER

  7. 5. Disruption of moth mating behaviour by olfactory and auditory cues

    Författare :Glenn Svensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; ultrasound; predation risk; selection; heritability; flight tunnel; harmonic radar; pest control; mating disruption; pheromone communication; Pyralidae; Lepidoptera; Noctuidae; Animal ecology;

    Sammanfattning : The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. LÄS MER
