  2. 1. Distribution and Chemical Diversity of Cyclotides from Violaceae : Impact of Structure on Cytotoxic Activity and Membrane Interactions

    Author : Robert Burman; Ulf Göransson; Lars Bohlin; William Gerwick; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cyclotide; Violaceae; Viola; Cytotoxic; Mechanism; In vivo; Structure-activity; Membrane; Mass spectrometry; Pharmacognosy; Farmakognosi; Pharmacognosy; Farmakognosi;

    Abstract : During the last decade there has been increased interest in the cyclotide protein family, which consist of a circular chain of approximately 30 amino acids, including six cysteines that form three disulfide bonds, arranged in a cyclic cystine knot motif. This thesis gives new insights in cyclotide distribution and occurrence in the plant family Violaceae, structure-activity relationships for cytotoxic effects, membrane disruption and adsorption on lipid membranes, and evaluates toxicity and anti-tumor activity in vivo.

  4. 2. High-temperature degradation of plasma sprayed thermal barrier coating systems

    Author : Robert Eriksson; Sten Johansson; Christer Burman; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Thermal barrier coating systems (TBCs) are used in gas turbines to prevent high-temperature degradation of metallic materials in the combustor and turbine. One of the main concerns regarding TBCs is poor reliability, and accurate life prediction models are necessary in order to fully utilise the beneficial effects of TBCs. READ MORE
