  1. 11. Blood pressure-dependent changes in plasma volume, glycocalyx and platelet function during anaesthesia -Clinical and experimental studies

    Författare :Tor Damén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; blood pressure; hypotension; norepinephrine; haematocrit; plasma volume; atrial natriuretic peptide; glycocalyx; platelet aggregation;

    Sammanfattning : Background: Worldwide, more than 300 million surgeries are performed each year. General anaesthesia provides the surgical patient with a state of controlled loss of sensation and awareness. It is common that general anaesthesia causes hypotension. Anaesthesia-induced hypotension is associated with haemodilution and increased plasma volume (PV). LÄS MER

  3. 12. Platelet adhesion and P-selectin surface expression

    Författare :Per A. Whiss; Nils Olav Solum; Linköpings universitet; []
    Nyckelord :divalent cations; ELISA; nicotine; nitric oxide; platelet adhesion; P-selectin; MEDICINE; MEDICIN;

    Sammanfattning : Upon injury in a blood vessel, platelets become activated and adbere to prevent blood loss. Activated platelets express adhesion molecules on their surface that also make leukocytes adhere to the injury. One such molecule, which also is expressed on endothelium, is the glycoprotein P-selectin. LÄS MER

  4. 13. Studies on effects of antioxidants on arterial thrombosis and endothelial cell injury : With special reference to Tocopherols and ApoA1 Milano

    Författare :Dayuan Li; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; tocopherols; apoA1 Milano; platelet aggregation; thrombosis; superoxide dismutase; nitric oxide synthase; endothelial cells; oxidized LDL; transcription factor; apoptosis; Kirurgi; Surgery; Kirurgi; rättsmedicin; Forensic Medicine;

    Sammanfattning : Coronary arterial endothelial injury and thrombosis are believed to be critical factors in the pathogenesis of coronary artery disease (CAD). Experimental studies have provided evidence for au inverse relation between acute coronary events and antioxidant intake. LÄS MER

  5. 14. Impact of Interleukin-6 family cytokine signalling on human endothelial cells and platelets

    Författare :Madelene Lindkvist; Magnus Grenegård; Liza Ljungberg; Alistair W. Poole; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gp130 signalling cytokines; inflammation; transsignalling; JAK STAT; MEK ERK; PI3K AKT; platelet aggregation; vasodilation;

    Sammanfattning : Endothelial cells lining the luminal side of blood vessels creates a barrier between the circulating blood and the extracellular matrix. Endothelial cells have important functions in regulation of vessel tension and inflammation. LÄS MER

  7. 15. Streptococcus pyogenes and its interactions with the human host

    Författare :Ulrika Ringdahl; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; mykologi; virologi; bakteriologi; M protein; Streptococcus pyogenes; plasminogen; fibrinogen; phagocytosis; platelet; Microbiology; bacteriology; virology; Mikrobiologi; mycology; Infektioner; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : We have found that a set of group A streptococcal strains, primarily associated with skin infections, express surface-associated M proteins that bind plasminogen and plasmin with high affinity. The binding is mediated by a common 13 amino acid internal repeated sequence located in the NH2-terminal surface-exposed portion of these M proteins. LÄS MER
