  1. 1. Susceptibility effects in MRI and 1H MRS. The spurious echo artifact and susceptibility measurements

    Författare :Åsa Carlsson; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; 1H MRS; susceptibility; spurious echo; artifact; artefact;

    Sammanfattning : When performing magnetic resonance (MR) experiments, a strong homogeneous magnetic field is often preferred, especially in clinical applications. However, all objects that are placed in the magnetic field will disturb the field homogeneity and cause local magnetic field gradients. LÄS MER

  2. 2. Towards Understanding of Selectivity & Enantioconvergence of an Epoxide Hydrolase

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Åsa Janfalk Carlsson; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; Epoxide; Enantioselectivity; Regioselectivity; Enantioconvergence; Crystal structures; Biocatalysis; Immobilization; Transient kinetics; CASTing; Directed evolution; Biokemi; Biochemistry;

    Sammanfattning : Epoxide hydrolase I from Solanum tuberosum (StEH1) and isolated variants thereof has been studied for mapping structure-function relationships with the ultimate goal of being able to in silico predict modifications needed for a certain activity or selectivity. To solve this, directed evoultion using CASTing and an ISM approach was applied to improve selectivity towards either of the enantiomeric product diols from (2,3-epoxypropyl)benzene (1). LÄS MER
