  2. 1. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

    Author : Pauline Vandoolaeghe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

    Abstract : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. READ MORE

  4. 2. Foreign molecules in biomembranes : Molecular effects on intact stratum corneum and model lipid systems

    Author : Quoc Dat Pham; Fysikalisk kemi; []
    Keywords : stratum corneum; lipid; keratin filament; protein; DMPC; penetration enhancer; osmolyte; solvent; monoterpene; fatty acid; hydration; molecular mobility; fluidity; permeability; PT ssNMR; diffusion cell;

    Abstract : This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular information.

  5. 3. Plant lipid transfer proteins : Evolution, expression and function

    Author : Monika Edstam; Johan Edqvist; Kristina Blomqvist; Jenny Hagenblad; Frederica Theodoulou; Linköpings universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

  6. 4. Spatial analysis of lipids in tissue samples applying mass spectrometry imaging

    Author : Masoumeh Dowlatshahi Pour; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SIMS; MALDI; Mass spectrometry imaging; Lipid; ME-SIMS; Sample preparation;

    Abstract : Lipids are important naturally occurring components in all living cellular organisms. They serve as the main building blocks of cellular membranes, participate in many signaling pathways and are also stored as an energy source. READ MORE

  7. 5. Lipid bilayers versus monolayers- Sponge phases and skin lipid domains

    Author : Katarina Ekelund; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatty acids; Langmuir-Blodgett films; AFM; domains; stratum corneum; bilayer curvature; lipids; glycerol monooleate; phase behaviour; sponge phase; L3 phase; Livsmedelsteknik; cholesterol; Food and drink technology;

    Abstract : The L3, or sponge, phase is a thermodynamically stable isotropic liquid consisting of a surfactant membrane in aqueous solution. A solvent induced L3 phase is shown in systems of solvent, monoolein and water. READ MORE
