  1. 16. Etiological and clinical studies of Langerhans cell histiocytosis (LCH)

    Författare :Selma Olsson Åkefeldt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Langerhans cell histiocytosis (LCH) is a rare disease of unknown origin. LCH may occur at any age but affects mainly children and the most severe forms of the disease are seen in the youngest children. In LCH, granulomatous lesions are formed in various organs. LÄS MER

  3. 17. Mitotic Kinesin-Like Protein 1 (MKLP1/KIF23) in hereditary congenital dyserythropoietic anemia type III and in cancer

    Författare :Ann-Louise Vikberg; Irina Golovleva; Monica Holmberg; Masanori Mishima; Pontus Aspenström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alternative splicing; Cell division; COPI; Congenital dyserythropoietic anemia; Cytokinesis; Gene expression; KIF23 protein human; Cancer; MKLP1 protein mouse; Mutation; medicinsk genetik; Medical Genetics;

    Sammanfattning : A hereditary form of autosomal dominant congenital dyserythropoietic anaemiatype III (CDA III) has been reported in four families from Sweden, Argentina, Cuba and USA. CDA III patients might experience signs of mild anaemia and some of them need occasional blood transfusions. LÄS MER

  4. 18. Ion Tracks for Micro- and Nanofabrication : From Single Channels to Superhydrophobic Surfaces

    Författare :Reimar Spohr; Lars Westerberg; Lars Montelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion track; single ion; real time; phase detection; conductometric cell; conductometry; electro replication; microtechnology; nanotechnology; surfactant; self organization; GMR; magnetic; sensor technology; hydrophobic; tilted texture.; Physics; Fysik; Materialvetenskap; Materials Science;

    Sammanfattning : A method is described for preset-count irradiations between 1 and 100 ions singling-out individual ions from an ion beam with more than a billion ions arriving per second. The ion tracks are etched in a conductometric system with real-time evaluation of the acquired data. The etch process can be interrupted when reaching a preset channel diameter. LÄS MER

  5. 19. Membrane-Polymer Interactions in Lipid Vesicles

    Författare :Ilona Wegrzyn; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipid nanotube; liposome; multifunctional pipette; PNIPAAm; lipid bilayer; giant unilamellar vesicle;

    Sammanfattning : Membrane related biological processes are commonly investigated in artificial biomimetic experimental systems. One of the most versatile models is based upon giant unilamellar phospholipid vesicles (liposomes), which are artificially generated spherical lipid structures in an aqueous environment. LÄS MER

  7. 20. Experimental radioimmunotherapy and effector mechanisms

    Författare :David Eriksson; Torgny Stigbrand; Eva Forsell-Aronsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radioimmunotherapy; apoptosis; mitotic catastrophe; caspases; cell cycle disturbances; combination treatment.; Immunology; Immunologi;

    Sammanfattning : Radioimmunotherapy is becoming important as a new therapeutic strategy for treatment of tumour diseases. Lately monoclonal antibodies tagged with radionuclides have demonstrated encouraging results in treatment of hematological malignancies. The progress in treatment of solid tumours using radioimmunotherapy, however, has been slow. LÄS MER
