  2. 16. Mechanisms behind the lipid-lowering effects of ACTH - Studies in different experimental models

    Author : Maria Skoog; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Lipid; ACTH; Apolipoprotein-B; Cholesterol; Human; Rat; Rabbit; Medicin människa och djur ;

    Abstract : Abstract Adrenocorticotrophic hormone (ACTH) has strong and direct lipid-lowering effects in man. All apoB-containing lipoproteins, i.e. VLDL, LDL, Lp(a), are reduced by 25-30%. READ MORE

  4. 17. Lipid Nanotube Networks: Shape Transitions and Insights into the Dynamics of Self-Organization

    Author : Tatsiana Lobovkina; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular nanotube; shape transition; enzymatic reaction; nanotube knot; self-organization; liposome; lipid nanotube; lipid vesicle; nanotube-vesicle network;

    Abstract : Nanotube-vesicle networks (NVNs) are simplified models of cell membrane tubular systems which are dynamic transportation routs for molecular cargoes in biological cells. The presented work describes dynamic properties of NVNs such as self-organization, shape and topology transformations; moreover, specific geometric properties of the networks are used for controlling enzymatic reactions.

  6. 19. 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.

  7. 20. Unravelling the structure and dynamics of lipid nanoparticles for biomolecule delivery

    Author : Jennifer Gilbert; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipid nanoparticles; neutron scattering; SAXS; protein encapsulation; nucleic acid delivery; lipid self-assembly;

    Abstract : 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.
