  1. 21. Trypsinogen and neutrophil activation in acute Pancreatitis

    Författare :Hannes Hartman Magnusson; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute pancreatitis; trypsinogen activation; adhesion; neutrophil extracellular traps;

    Sammanfattning : Background and aims: Acute pancreatitis (AP) is a common condition characterized by premature protease activation, abdominal pain and leakage of pancreatic enzymes to the circulation. Approximately 10% develop systemic inflammation and persistent organ failure. LÄS MER

  3. 22. Platelet activation and aggregation: Clinical and experimental studies

    Författare :Sukhi Singh; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Platelet concentrate; Adrenaline; Noradrenaline; Ticagrelor; Platelet aggregation; Platelet activation;

    Sammanfattning : Background: Dual antiplatelet therapy with acetylsalicylic acid (ASA) and the adenosine diphosphate (ADP)-receptor antagonist ticagrelor increases the risk of bleeding complications during cardiac surgery. The overall aim of this thesis was to identify and evaluate current and potential methods to reduce and prevent bleeding complications in patients with ongoing antiplatelet therapy. LÄS MER

  4. 23. Endothelial activation and inflammation in the tumor microenvironment

    Författare :Hua Huang; Anna Dimberg; William C. Aird; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tumor angiogenesis; endothelial activation; leukocyte recruitment; VEGF-A; αB-crystallin; ELTD1;

    Sammanfattning : Tumors are composed not only of malignant cells, but also of various types of normal cells, including vascular cells and infiltrating immune cells, which drive tumor development and progression. The tumor vasculature is abnormal and dysfunctional due to sustained tumor angiogenesis driven by high levels of pro-angiogenic factors. LÄS MER
