  1. 6. Leukocyte receptor alternations during systemic inflammatory responses

    Författare :Olof Ljunghusen; Per Venge; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The leukocyte adhesion molecule CD llb is very important when granulocytes and monocytes leave the blood stream. This adhesion molecule is stored preformed intracellularly, and can upon stimulation of the cells by, for example, complement split products, be mobilized to the cell surface. LÄS MER

  3. 7. Benthic environmental responses to climatic changes during the late Quaternary: a micropalaeontological and geochemical approach

    Författare :Claire McKay; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; late Quaternary; rapid climate change; Benguela; Mauritania; productivity; upwelling; benthic foraminifera;

    Sammanfattning : There is a limited understanding of how the benthic environment within upwelling regions responded to past rapid climatic changes. Within this thesis, a multiproxy approach is applied to two marine sediment cores from two coastal upwelling sites in the low latitude subtropical Atlantic. LÄS MER

  4. 8. Precise cell manipulations and imaging of cellular responses : Methods developed using microfluidic, 3D-printing and microfabrication technologies

    Författare :Nikos Fatsis-Kavalopoulos; Johan Kreuger; Aman Russom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : It is at the heart of biological and medical research to try and understand how cells communicate with each other, and how cells respond to alterations in their environment, including treatment with different drugs. There is in this context a continued need for better methods that allow researchers to precisely manipulate cells and their microenvironment and to study the resulting responses using high-resolution live microscopy.

  5. 9. Characterization and environmental influences on inflammatory and physiological responses

    Författare :Hazem Khalaf; Per-Erik Olsson; Joe de Pierre; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inflammation; NF-κB; cytokines; pharmaceuticals; zebrafish; Biology; Biologi; NATURAL SCIENCES; NATURVETENSKAP; Biology; Biologi;

    Sammanfattning : Pharmaceuticals are regularly released into the environment, in particular nonsteroidalanti-inflammatory drugs (NSAIDs) and antibiotics. The measuredconcentrations are relatively low and have therefore been considered to be harmless. LÄS MER

  7. 10. Plant responses after drainage and restoration in rich fens

    Författare :Kalle Mälson; Håkan Rydin; Sebastian Sundberg; Harri Vasander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; brown mosses; bryophytes; colonization; competition; dispersal limitation; liming; mire; peatland; rewetting; wetland restoration; Ekologi;

    Sammanfattning : Rich fens are an important, but threatened, habitat type in the boreal landscape. In this thesis I have examined responses of rich fen vascular plants and bryophytes after drainage and restoration.The effects of drainage on the rich fen flora were observed in a long time study and the responses were rapid and drastic.
