  1. 1. Cyclooxygenase-2 inhibitors and knee prosthesis surgery

    Författare :Andreas Meunier; Lars Good; Per Aspenberg; Tore Dalén; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-steroidal anti-inflammatory agents; administration dosage; Arthroplasty; knee replacement; Surgical blood loss; Surgery; Cyclooxygenase inhibitors; Cyclooxygenase inhibitors; Fracture healing; Isoxazoles; Postoperative pain; Pyrazoles; Sulfonamides; Surgery; Kirurgi;

    Sammanfattning : Adverse effects of cyclooxygenase (COX) inhibitors on bone healing have previously been demonstrated in diaphyseal fracture models in animals. In spite of that, they are widely used as postoperative analgesics in orthopaedic surgery. After joint replacement, a bone repair process starts at the interface between bone and cement. LÄS MER

  2. 2. The Role of Cyclooxygenase-2 in Models of Epilepsy and Traumatic Brain Injury : Effects of Selective Cyclooxygenase-2 Inhibitors

    Författare :Tina Kunz; Tadeusz Wieloch; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Controlled cortical contusion injury; fluid percussion injury; limbic seizures; nuclear factor-kappa B; prostaglandin metabolism; TUNEL staining; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : Cyclooxygenase-2 (COX-2) catalyses prostaglandin synthesis from arachidonic acid during inflammation. COX-2 is expressed in the normal brain and is induced in neurological disorders. There is evidence that COX-2 is involved in secondary events leading to cell death in the brain. LÄS MER

  3. 3. Cyclooxygenase activity and tumor progression

    Författare :Christian Cahlin; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cyclooxugenase; PGE2; inflammation; cytokine; nitric oxide; indomethacin; IL-6;

    Sammanfattning : Invasive growth of malignant tumors is associated with local and systemic inflammation, which may promote progression and metastases. Inflammation is also responsible for appearing manifestations of advanced cancer as fatigue, anorexia and wasting with eicosanoids, proinflammatory cytokines and nitric oxide as mediators. LÄS MER

  4. 4. Studies of prostaglandin E2 formationin human monocytes

    Författare :Sofia Karlsson; Jonny Wijkander; Christina Gustafson-Svärd; Karlstads universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostaglandin E2; arachidonic acid; phospholipase A2; cyclooxygenase; prostaglandin E synthase; human monocytes; Medical cell biology; Medicinsk cellbiologi; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Prostaglandin (PG) E2 is an eicosanoid derived from the polyunsaturated twenty carbon fatty acid arachidonic acid (AA). PGE2 has physiological as well as pathophysiological functions and is known to be a key mediator of inflammatory responses. LÄS MER

  5. 5. Role of Inducible Nitric Oxide Synthase and Melatonin in Regulation of β-cell Sensitivity to Cytokines

    Författare :Annika K. Andersson; Stellan Sandler; Nils Welsh; Décio L. Eizirik; Nils Billestrup; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; β-cell; Cyclooxygenase; Cytokine; Diabetes; IFN-γ; IL-1β; iNOS; Insulin; Melatonin; Nitric oxide; Pancreatic islets; Phospholipase D; Prostaglandin E2; Streptozotocin; Cellbiologi; Cell biology; Cellbiologi;

    Sammanfattning : The mechanisms of β-cell destruction leading to type 1 diabetes are complex and not yet fully understood, but infiltration of the islets of Langerhans by autoreactive immune cells is believed to be important. Activated macrophages and T-cells may then secrete cytokines and free radicals, which could selectively damage the β-cells. LÄS MER
