  1. 21. Gastroduodenal epithelial transport in patients with cystic fibrosis

    Författare :Karin Edshage Hallberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cystic fibrosis; CFTR; intestinal motility; gastric secretion; IgA; Ussing chamber; intestinal permeability; genotype;

    Sammanfattning : Cystic fibrosis (CF) is an inherited disease where respiratory failure due to chronic lung infection is the major cause of death. A defective protein, cystic fibrosis transmembrane conductance regulator (CFTR) alters chloride epithelial transport. LÄS MER

  3. 22. Isolation, Characterization and Material Properties of Arabinoxylan from Barley

    Författare :Anders Höije; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical structure; moisture content; film formation; Arabinoxylan; isolation; mechanical properties; oxygen permeability;

    Sammanfattning : The growing amount of household waste and the limited supply of fossil fuel on earth make it important to find renewable resources for the production of biodegradable polymers for a variety of applications, particularly as packaging and other disposable products. Hemicelluloses are important components in all plants and the second most abundant plant biopolymers on earth. LÄS MER

  4. 23. Characterization of artificial and biological lipid vesicles using TIRF and SPR

    Författare :Thomas Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane permeability; chromaffin vesicle; fluorescence; total internal reflection TIRF microscopy; surface plasmon resonance SPR ; vesicle; osmotic shock; cell membrane; liposome; nanoparticle tracking analysis NTA ; large dense core vesicles LDCVs ;

    Sammanfattning : Synthetic lipid vesicles serve as important mimics of cells and the natural membranes that they are enclosed by. As such they are frequently used as simplified models of the highly complex cell membrane to aid in-depth physicochemical and biological characterization of this essential biological structure.

  5. 24. Permeability modelling and particle deposition mechanisms related to advanced composites manufacturing

    Författare :Markus Nordlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Advanced composite materials reinforced by Non-Crimp Fabrics (NCFs) are becoming increasingly popular for high performance, light weight, complex structures, due to their high mechanical properties and relatively cheap production costs. These materials, not only improve the structural properties, but also induce great possibilities for reduced fuel consumptions for aircrafts and automotives, due to their high strength to weight ratio.

  7. 25. Barrier Plastics, Processing of Wheat Gluten and A New Method to Measure Permeability

    Författare :Henrik Ullsten; KTH; []
    Nyckelord :;

    Sammanfattning : One way to extend the shelf life for foodstuff is to usemodified atmosphere packaging (MAP). It is important that MAPare gas tight or in some rare cases permselective to preservethe right gas mix. LÄS MER
