1. Fatty Acid Composition in Skeletal Muscle : Influence of Physical Activity and Dietary Fat Quality
Sammanfattning : Insulin sensitivity is related to the fatty acid profile of skeletal muscle. The aim of this thesis was to investigate whether physical activity and dietary fat quality, independent of each other, influence the fatty acid composition of the skeletal muscle lipids. LÄS MER
2. Unravelling the structure and dynamics of lipid nanoparticles for biomolecule delivery
Sammanfattning : Encapsulation in self-assembled lipid structures has been shown to increase the stability of large biomolecules, including proteins and nucleic acids (NAs), which has many potential applications in the food and pharmaceutical industries. In order to fully optimise the encapsulation system for a certain application, however, it is important to understand the effect of the encapsulated biomolecule on the lipid structure and vice versa.

3. Lipid Vesicle Fusion: Investigation, Generation and Manipulation of Cell-Membrane Mimics
Sammanfattning : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. In this work, cell-membrane mimics were constructed and evaluated as models for studies of the membrane-fusion process. LÄS MER
4. Formation of Mesoporous Materials and their use as Lipid Bilayer Supports
Sammanfattning : Mesoporous materials have acquired great scientific interest in various applications; something that is largely due to that their properties, such as pore size, pore orientation, material composition and surface chemistry, can be controlled to a large extent. One idea, which has been investigated in this thesis, is to use mesoporous materials as supports for lipid bilayers and by doing so fabricate devices that mimic the cell wall and at the same time has sufficient mechanical robustness for practical use.

5. Plant lipid transfer proteins : Evolution, expression and function
Sammanfattning : The plant non-specific lipid transfer proteins (nsLTPs) are known for the ability to transfer different lipids in vitro, but their in vivo functions have not yet been elucidated. They seem to play a role in the defense against biotic and abiotic stresses; the gene expression of nsLTPs is often upregulated when exposed to stresses. LÄS MER
