  1. 1. 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.

    Sammanfattning : This study investigates pathways by which the eicosanoid precursor pools in the platelets, bone marrow and the gastrointestinal (GI) mucosa are acquired and regulated, and in this context some aspects on the interaction between triglyceride (TG)-rich lipoproteins and platelets. 1.

  4. 3. Fat metabolism : A clinical and experimental study with special reference to newborns

    Författare :Gertrud Angsten; Karl-Anders Dahlström; Uppsala universitet; []

    Sammanfattning : Lipid emulsion is an important constituent of total parenteral nutrition (TPN). In the investigations described in this thesis the effects of different lipid emulsions in neonates were studied. LÄS MER

  5. 4. Arachidonic acid metabolism in corneal epithelial cells : Identification of lipoxygenase isoforms

    Författare :Maria Liminga; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Interaction of Triglyceride-rich Lipoproteins with Platelets and Vitamin K-dependent Coagulation Factors

    Författare :Ning Xu; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Triglycerides.; Prothrombin; Protein S; Protein C; Platelets; Phospholipids; Metabolism; Lipoproteins; Lipids; Endocytosis; Electron microscopy; Cytochemistry; Coronary heart disease; Blood coagulation factors; Arachidonic acid; Atherosclerosis; Clinical chemistry; Klinisk kemi; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

    Sammanfattning : 1. During incubation of platelets with 3H-arachidonic acid (20:4, n-6) and 14C-cholesterol doubly labelled and colloidal gold labelled chylomicrons (CMs) and chylomicron remnants (CMRs) CMs were taken up more efficiently than CMRs. Addition of unlabelled CMs, VLDLs, LDLs and HDLs decreased the uptake of labelled CMs. LÄS MER
