  1. 11. Angiogenesis in childhood malignancies

    Författare :Erik Sköldenberg; Rolf Christofferson; Göran Läckgren; Agneta Nordenskjöld; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Angiogenesis Factor; Biopsy; Needle; Neovascularization; Pathologic; Nephroblastoma; Reference value; Kirurgi; Surgery; Kirurgi; Pediatric Surgery; kirurgi; särskilt barnkirurgi;

    Sammanfattning : Angiogenesis is necessary for the growth and spread of solid tumors. In these studies angiogenesis was measured in childhood malignancies in general and in Wilms’ tumor in particular, and cutting needle biopsy (CNB) specimens were evaluated for diagnosis in childhood renal tumors.

  2. 12. Fabrication of new silica nano structures and development of new concepts for MALDI-TOF mass spectrometry

    Författare :Andreas Woldegiorgis; Johan Roeraade; Peter J. Schoenmakers; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : A technique to alter the morphology of the inner surface of fused silica capillaries has been developed. The internal surface area is enlarged by means of nano-wires of silica, which are grown from the capillary walls. LÄS MER

  3. 13. In vivo imaging of leukocyte-endothelium interactions in septic lung injury

    Författare :Jonas Roller; Kirurgi; []
    Nyckelord :Sepsis; Acute lung injury; Leukocyte recruitment; Intravital fluorescence microscopy;

    Sammanfattning : Excessive accumulation of leukocytes in the lung represents a key feature in the development of an acute lung injury (ALI). Numerous studies demonstrated that leukocyte rolling is a compulsory precondition for the firm adhesion in organs. However, it seems that the recruitment process of leukocytes in the lung is more complex. LÄS MER

  4. 14. Guiding of highly charged ions through insulating nanocapillaries

    Författare :Hongqiang Zhang; Reinhold Schuch; Amine Cassimi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Atomic physics; Atomfysik; fysik; Physics;

    Sammanfattning : This thesis contains experimental work on guiding of highly charged ions through insulating nanocapillaries. We have studied the time evolution of angular distributions of transmitted ions under well defined initial conditions: already charged, as well as fully discharged nanocapillaries, by using a two-dimensional position sensitive Micro Channel Plate detector with a data acquisition system working in event mode.

  5. 15. Extracellular Matrix and Actin Cytoskeleton - the Control Unit of Interstitial Fluid Volume

    Författare :Vahid Reyhani; Kristofer Rubin; Markella Ponticos; Uppsala universitet; []
    Nyckelord :Collagen; fibrin; integrins; PDGF-BB; gel contraction; fluid homeostasis; interstitial fluid pressure; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : The regulation of fluid (water) volume in the body is crucial for tissue homeostasis. The interstitial fluid, which comprises almost 20% of the body fluid, is stored in the loose connective tissue and its volume is actively regulated by components of this tissue. LÄS MER
