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

    Författare :Andreas Meunier; Lars Good; Per Aspenberg; Tore Dalén; Linköpings universitet; []
    Nyckelord :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

  4. 3. Luminal Hypotonicity and Duodenal Functions : An Experimental Study in the Rat

    Författare :Liselotte Pihl; Olof Nylander; Gunnar Flemström; Mats Jodal; Uppsala universitet; []
    Nyckelord :Physiology; luminal alkalinization; mucosal permeability; osmolality; cyclooxygenase-2; rat; duodenum; jejunum; motility; enteric nervous system; Fysiologi;

    Sammanfattning : After drinking water, the fluid quickly leaves the stomach thereby creating a hypotonic luminal environment in the duodenum. This in turn constitutes a potential threat to the integrity of the duodenal epithelium. It therefore seems highly likely that luminal hypotonicity activates physiological mechanisms that aim to increase luminal osmolality. LÄS MER

  5. 4. Endocannabinoid metabolism : the impact of inflammatory factors and pharmacological inhibitors

    Författare :Jessica Karlsson; Christopher Fowler; Stig Jacobsson; Jürg Gertsch; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endocannabinoid; anandamide; 2-AG; fatty acid amide hydrolase; cyclooxygenase-2; prostate cancer; catabolism; inflammation; inflammatory factors;

    Sammanfattning : The endocannabinoid (eCB) system is an endogenous signaling system consisting of ligands (referred to as endocannabinoids, eCBs), receptors and metabolic enzymes. The eCB system is involved in homeostatic control of a variety of biological functions such as neuronal signaling, mood, appetite and pathological conditions such as pain, inflammation and tumour progression.

  7. 5. Influence of leukotriene D4 and cyclooxygenase-2 on cell survival

    Författare :Katarina Wikström; Malmö Experimentell patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pathological anatomy; Patologi allmän ; General pathology; colorectal cancer; inflammation; apoptosis; LTD4; COX-2; patologisk anatomi;

    Sammanfattning : The pro-inflammatory effect of leukotrienes is an important element in the pathogenesis of multiple disorders, including asthma and inflammatory bowel diseases (IBD). A serious concern for IBD patients is the increased risk of developing colorectal cancer and since there seems to be a general connection between inflammation and cancer we hypothesised that LTD4 induced signalling events could be involved in increasing the tumourgenic potential of cells.
