  1. 1. Melanophore signaling : regulation and application

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Tony P. M. Andersson; Ethan Lerner; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Sammanfattning : Melanophores are pigment-containing cells responsible for quick physiological color changes in lower vertebrates due to redistribution of melanosomes, pigment granules. We have studied melanophores from African clawed frog, Xenopus laevis. LÄS MER

  2. 2. Chemoattractant receptor signaling and neutrophil acctivation. Involvement of the cytoskeleton

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Huamei Fu; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; G-protein coupled receptors; signaling; cytoskeleton;

    Sammanfattning : Neutrophil granulocytes play a vital role in the host surveillance system and form the first line of defense against microbial infections. The migration of neutrophils to an infected/inflamed tissue is guided by chemoattractants released either from intruding microbes or from activated/damaged host cells. LÄS MER

    Sammanfattning : This dissertation contributes to the debate on street-level bureaucracy, which highlights how the decisions made by workers in public bureaucracies effectively become public policy. This debate has paid relatively little attention to the study of how professionals carry out their work by means of institutional categorization, a knowledge gap that this study helps to close.

  4. 4. Signaling and Adhesive Mechanisms in Acute Pancreatitis

    Detta är en avhandling från Lund University

    Författare :Darbaz Awla; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; trypsinogen activation; Acute pancreatitis; leukocyte recruitment and adhesion;

    Sammanfattning : Acute pancreatitis (AP) is an inflammatory disease with variable severity ranging from mild interstitial edematous to severe necrotizing disease. The overall mortality rate of AP is 8-9%. Specific treatment of AP is lacking which is partly related to an incomplete understanding of the basic pathophysiology behind the disease. LÄS MER

  5. 5. Calcium signaling : Molecular mechanisms and cellular consequences

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medical Biochemistry and Biophysics

    Författare :Seth Malmersjö; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cells exploit calcium (Ca2+) signaling to transmit information. In a multicellular organism, each cell must be able recognize, process, and respond to information received from the surrounding environment. In this thesis I investigate molecular mechanisms and cellular consequences of Ca2+ signaling. LÄS MER
