  2. 6. Small bowel obstruction and toxicity of a new model of adhesion prevention

    Author : Karolin Isaksson; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small bowel obstruction; predictive parameters; appendectomy; open versus laparoscopic; abdominal adhesions; prevention; polypeptides; toxicity; biodistribution;

    Abstract : Abstract Background: Small bowel obstruction (SBO) is a common surgical diagnosis. If no signs of strangulation are evident, the majority of the patients can be conservatively managed. Approximately one third of the patients need surgical treatment and there is a need for early parameters that can predict operative intervention. READ MORE

  4. 7. Multilayer Structures for Biomaterial Applications : Biomacromolecule-based Coatings

    Author : Tobias Halthur; Per M. Claesson; Bjørn Stokke; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multilayer; layer-by-layer deposition; physical chemistry; surface chemistry; adsorption; ellipsometry; QCM-D; DPI; protein adsorption; polypeptides; biomaterials; biosurfaces; amelogenin; solid liquid interface; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : The cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied.

  5. 8. Conformation of polypeptides at nanoparticles interfaces : protein structural changes and induced folding of peptides

    Author : Martin Lundqvist; Fredrik Höök; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis can be divided into two parts. The first deals with characterization of structural and dynamic consequences for proteins of interactions with a solid surface in the form of silica nanoparticles. READ MORE

  6. 9. Immunological analysis of the human tumor cell surface : characterization of polypeptides associated with urinary bladder carcinoma

    Author : Staffan Paulie; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Tumors express antigens characteristic of their malignant phenotype, a fact that has become exploited for the diagnosis of certain types of cancer. As these tumor-associated antigens (TAA) may also provide Information on the molecular mechanisms of tumorogenesls as well as constituting the basis for immunotherapeutlc approaches, much Interest has been focused on the Identification and characterization of TAAs.

  7. 10. POLYPEPTIDES - STRUCTURES AND INTERACTIONS IN MONOLAYERS AND AQUEOUS SOLUTIONS

    Author : Helen Sjögren; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; tyrosine ; co-poly-L lysine; phenylalanine ; co-poly-L- lysine; poly-L-glutamate; poly-L-lysine; poly-L-valine; poly-L-isoleucine; poly-gamma-methyl-L-glutamate; poly-L-leucine; monolayer; Langmuir-Blodgett film; CD spectroscopy; random coil; alpha-helix; surfactant stabilisation; polypeptide; polyamino acid;

    Abstract : The aim of this thesis work is to understand and be able to control polypeptide conformation and interactions at interfaces and in solution by changing the solution conditions. For this purpose simple model polypeptides, so-called polyamino acids, have been investigated at the air-liquid interface, as well as in aqueous solutions. READ MORE
