  1. 1. PEG and lipids in solid dispersions and liquid crystals - structure and phase behaviour

    Författare :Johan Unga; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; bicontinuous sponge phase; polyethylene glycol; monoolein; bicontinuous cubic phase; lipids; differential scanning calorimetry; phytantriol; small angle X-ray diffraction; solid dispersions;

    Sammanfattning : In this thesis, two different kinds of nano-structured systems have been studied; solid dispersion systems of polyethylene glycol (PEG) and liquid crystalline systems containing the polar lipids monoolein (MO) and phytantriol (PT). Solid dispersions of PEG were studied with addition of different substances, lipids or parabens. LÄS MER

    Sammanfattning : In this thesis, the interaction between lipids, solvents and active substances in lipid based formulations have been studied and related to formulation structure or release behavior on human skin or a model thereof. For the different investigations, isotropic equilibrium lipid phases, i.e. LÄS MER

  4. 4. On the crystallization of membrane proteins in lipidic sponge and cubic phases

    Författare :Pia Jeanette Hindrichsen; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

    Sammanfattning : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. LÄS MER
