1. 16. Plant aquaporin regulation: Structural and functional studies using diffraction and scattering techniques

   Författare :Michael Järvå; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray Crystallography; Membrane protein; Plasma membrane intrinsic protein; Aquaporin; pH gating; mercury; proteoliposome assay; water transport; SANS; SAXS; WAXS; nanodisc; liposome;

   Sammanfattning : Water is the basis for life as we know it. It is only logical then that all organisms have evolved specialized proteins, aquaporins, which regulate water flow across their membranes. Plants, which are immobile, depend more on their environment and also use water flows to move, to breathe, and to grow. LÄS MER

3. 17. alpha-synuclein: amyloid fibrils and interactions with lipid membranes

   Författare :Marija Dubackic; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alpha-synuclein; model lipid membranes; amyloid fibrils; Parkinson s disease; Lewy bodies; SANS; SAXS;

   Sammanfattning : The second most common neurodegenerative disease, Parkinson’s disease, is linked with an amyloid forming protein, alpha-synuclein. Hallmarks of Parkinson’s disease are progressive loss of dopaminergic neurons and accumulation of intraneuronal inclusions termed Lewy bodies. LÄS MER

4. 18. Phase Equilibria and Structures of Oppositely Charged Polymers and Surfactants in Water

   Författare :Anna Svensson; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self diffusion; PFG NMR; hexagonal; cubic Pm3n; liquid crystals; SAXS; polymer; counterion; complex; polyelectrolyte; surfactant; Monte Carlo simulations; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : A new approach to the study of aqueous mixtures of oppositely charged polymers and surfactants has been introduced. Pure polyion-surfactant ion complex salts have been synthesized and used as the point of departure. The elimination of the simple ions reduces the number of components in the mixtures, thus greatly simplifying the system. LÄS MER

5. 19. ALA and m-ALA in bicontinuous lipid formulations: -Characterization and Transdermal Delivery

   Författare :Johanna Bender; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; passive diffusion; SAXS; monoolein; methyl 5-aminolevulinate hydrochloride; NMRD; sponge phase; 5-aminolevulinic acid hydrochloride; iontophoresis;

   Sammanfattning : δ-Aminolevulinic acid (ALA) and its methyl ester (m-ALA) are both used in photodynamic therapy (PDT) of certain non melanoma skin cancers as the basal cell carcinoma (BCC). In PDT the cancer cells are destroyed by a photochemical reaction that occurs when a photosensitive molecule is irradiated with light of a certain wavelength. LÄS MER

7. 20. Association of Amphiphiles and Polyelectrolytes with DNA

   Författare :Yulia S Mel'nikova; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; cryo-TEM; SAXS; fluorescence microscopy; DNA condensation; DNA-polyelectrolyte; DNA- amphiphile interactions; Fysikalisk kemi;

   Sammanfattning : DNA- cationic amphiphile and DNA-cationic polymer systems were studied with respect to the intermolecular interactions, as well as structure and stability of formed complexes. The thesis is divided in two parts: one section is a summary and the other section contains five papers. LÄS MER
