1. Extinctions and Ecosystem Stability
Abstract : Human society's expansion and demand for both biotic and abiotic natural resources exert a large pressure on ecosystems around the globe. Ecosystems are complex networks of species interacting with each other and their physical surroundings. READ MORE

2. Sweet stability
Abstract : The disaccharide trehalose is known for its ability to stabilise proteins by preventing aggregation and elevating their denaturation temperature, consequently avoiding unfolding. The folding and function of proteins are vital for many biological processes. READ MORE

3. Liposomes for Drug Delivery : from Physico-chemical Studies to Applications
Abstract : Physico-chemical characterisation of structure and stability of liposomes intended for drug delivery is the central issue in this thesis. In addition, targeted liposomes to be used in boron neutron capture therapy (BNCT) were developed.Lysolipids and fatty acids are products formed upon hydrolysis of PC-lipids. READ MORE

4. Sterically stabilised liposomes and related lipid aggregates : Fundamental studies on aggragate structure and stability
Abstract : Various aspects of and approaches towards the steric stabilisation of liposomes have been investigated, mainly by use of fluorescence techniques and cryo-transmission electron microscopy (cryo-TEM). It is shown that PEG(2000)-lipids can be incorporated in the liposome membrane up to a critical concentration of 8-10 mol% without any observable structural perturbations. READ MORE

5. Structure and stability of liposomes : Interactions with micelle- forming surfactants
Abstract : The stability of phospholipid lipomes interacting with micelle-forming surfactants was studied under physiological conditions (150 mM NaCl and pH=7.4 unless otherwise stated) mainly by use of cryo-TEM and fluorescence. READ MORE
