  2. 21. 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.

  4. 22. Interactions between polymers and the environment

    Author : Nazanin Alipour; Mikael S. Hedenqvist; Antal Boldizar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deltamethrin; piperonyl butoxide; polyethylene; migration; multilayer film; EVOH; n-hexane; crystallization; mechanical properties; X-ray scattering; swelling; larvae; protein; lipid; moisture sorption; release; nanoclay; polypropylene; degradation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : This dissertation addresses the structure and properties of a number of polymer-based materials when they come into contact with specific environments. The first part describes the migration and depletion of active substances from insecticide-impregnated polyethylene sheets in water and air at different humidity levels and higher temperatures.

  5. 23. Cyanobacteria in symbiosis with plants : Protein patterns and regulatory mechanisms

    Author : Martin Ekman; Birgitta Bergman; Dave G. Adams; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; symbiosis; Nostoc; Gunnera; Azolla; nitrogenase; modification; heterotrophic; proteomics; unsequenced; Plant physiology; Växtfysiologi;

    Abstract : Cyanobacteria belonging to the heterocystous genus Nostoc, capable of oxygenic photosynthesis and nitrogen fixation via the enzyme nitrogenase, may form symbiotic associations with plants. In these associations most of the N2 fixed by the symbiotic cyanobacteria (cyanobiont) is transferred to the host, which in turn supplies the cyanobiont with fixed carbon. READ MORE

  6. 24. Micro-RNA: The “Micro”-managers of cardiovascular diseases - Role of extracellular vesicles-mediated miRNAs in cardiovascular diseases

    Author : Kreema James; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiology; molecular biology; extracelluar vesicles; Micro-RNA; Protein;

    Abstract : Cardiovascular disease (CVD) is the leading cause of death globally, impacted by both extrinsic and intrinsic factors. The disease at the molecular level, however, is governed by inflammation and characterized by endothelial dysfunction. READ MORE

  7. 25. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

    Author : Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Abstract : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.
