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

    Author : Tina Kunz; Tadeusz Wieloch; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 7. Arachidonic acid metabolism in corneal epithelial cells : Identification of lipoxygenase isoforms

    Author : Maria Liminga; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Cornea; cDNA cloning; lipoxygenase; liquid chromatography-mass spectrometry; organ culture; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : The metabolism of arachidonic acid in the human cornea was investigated and compared with the metabolism in cattle and primates. All three species showed significant arachidonic acid metabolism inthe epithelium, whereas the activity in the stroma and the endothelium was low or undetectable. READ MORE

  3. 8. The Role of the Melanocortin System in Linking Energy Homeostasis with Reward Mechanisms

    Author : Jonas Lindblom; Per Södersten; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : There is evidence of a link between peripheral signals of energy homeostasis and reward mechanisms. A hypothesis was formulated that the melanocortin (MC) system is part of this link. The hypothesis was tested by a series of receptor expression and neurochemical studies in rats. READ MORE

  4. 9. Cytochrome P450 Enzymes in the Metabolism of Cholesterol and Cholesterol Derivatives

    Author : Maria Norlin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : Cholesterol is metabolized to a variety of important biological products in the body including bile acids and vitamin D. The present investigation is focused on enzymes that catalyze 7α-hydroxylation or 27-hydroxylation in the metabolism of cholesterol, oxysterols (side chain-hydroxylated derivatives of cholesterol) and vitamin D3.

  5. 10. Involvement of the Opioid System in High Alcohol Consumption : Environmental and Genetic Influences

    Author : Karolina Ploj; Jörgen A Engel; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Opioids; ethanol; stress; maternal separation; neonatal handling; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : It is well accepted that both inherent and environmental factors influence the pathogenesis of alcohol dependence. This thesis investigates the role of the opioid system in the initiation and maintenance of high ethanol intake. READ MORE
