  1. 1. Platelet-activating factor, intestinal epithelial cells, and Chron's disease : An experimental study

    Författare :Bengt Kald; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Platelet-activating factor (PAF-acethcr, 1-0-alky l-2-acetyl-s n- glycero-3- phosphocholine), is a potent inflammatory mediator that can be formed by a variety of cells and tissues. In the present investigation, the content of PAFacether was determined in mucosal biopsies from the ileum and colon of patients with Crohn's disease and control patients. LÄS MER

  3. 2. Role of platelet-activating factor in sepsis and shock : an experimantal study

    Författare :Fikri M. Abu-Zidan; Bengt Gerdin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Objectives: To study the role of platelet-activating factor (PAF) on cardiovascular and pulmonary dysfunction in sepsis and shock.Design: Experimental study. Setting: Trauma research unit, university department of surgery, Sweden.Material: 76 juvenile domestic pigs. LÄS MER

  4. 3. The Role of Chlamydia pneumoniae-induced Platelet Activation in Cardiovascular Disease : In vitro and In vivo studies

    Författare :Hanna Kälvegren; Torbjörn Bengtsson; Arina Richter; Erik Kihlström; Kenneth Persson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chlamydia pneumoniae; Platelet; atherosclerosis; Infection; LDL-oxidation; Percutaneous coronary intervention; Cardiovascular disease; Serotonin; Reactive oxygen species production; Pharmacology; Farmakologi;

    Sammanfattning : The common risk factors for atherosclerosis, such as obesity, high cholesterol levels, sedentary lifestyle, diabetes and high alcohol intake, only explain approximately 50% of cardiovascular disease events. It is thereby important to identify new mechanisms that can stimulate the process of atherosclerosis. LÄS MER

  5. 4. Platelet-derived growth factor-induced signal transduction

    Författare :Sigrídur Valgeirsdóttir; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Cellbiologi; Cell biology; Cellbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Platelet-derived growth factor (PDGF), a potent mitogen for mesenchymal cells, elicits its effects by binding to cell surface tyrosine kinase receptors, denoted α- and β-receptors. This thesis describes the mechanism of interaction between stimulated PDGF receptors and various intracellular molecules. LÄS MER

  7. 5. Crosstalk Between Activated Platelets and the Complement System

    Författare :Osama A. Hamad; Bo Nilsson; Kristina Ekdahl-Nilsson; Lennart Truedsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; platelets; activated platelets; TRAP; chondroitin sulfate; C1q; factor H; C4BP; C3; Compstatin; complement; platelet-leukocyte complexes; platelet microparticles; Clinical immunology; Klinisk immunologi; Klinisk immunologi; Clinical Immunology;

    Sammanfattning : Several studies have shown that complement and thrombotic events co-exist. Platelets have been suspected to act as the bridge between the two cascade systems. LÄS MER
