  1. 1. Reactivity of human omental blood vessels. Effects of 5-hydroxytryptamine, substance P and the intravenous anaesthetic propofol

    Författare :Susanna Wallerstedt; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensivvård; intensive care; Anaesthesiology; endothelium; calcium; human; hyperpolarization; K channels; nitric oxide; omental artery; omental vein; propofol; receptors; Anestesiologi; serotonin; sympathetic nervous system; substance P;

    Sammanfattning : Regulation of blood flow involves several endogenous substances and mechanisms, and exogenous substances may also affect the blood flow. In the present thesis, human omental blood vessels were investigated in vitro concerning (i) characteristics of 5-hydroxytryptamine (5-HT) receptors; (ii) mediators of substance P (SP)-induced relaxation; (iii) direct and indirect (via effects on sympathetic neurotransmission) effects of the intravenous anaesthetic propofol.

    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

  4. 3. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands

    Författare :Stefan Jonsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; X-ray crystallography; Phenanthroline; Supramolecular Catalysis; Jacobsen-Katsuki Epoxidation; Mn salen ; Hydrogen-bonding; Supramolecular Chemistry; 2-Pyridone; Organisk kemi;

    Sammanfattning : This thesis concentrates on the development, synthesis and evaluation of supramolecular systems, assembled from its components by means of hydrogen bonding, using the self-complementary 2-pyridone motif. The thesis is divided in two parts. LÄS MER

  5. 4. Deltagande och inflytande gällande redovisningsregler för mindre företag

    Författare :Fredrika Askenmalm; Kristina Artsberg; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Denna uppsats fokuserar på vilka som deltagit och vilka som haft inflytande då nya redovisningsregler för mindre företag skapas.Det pågår en revidering av de svenska redovisningsreglerna. Bokföringsnämnden (BFN) har av regeringen fått i uppdrag att utveckla ett nytt regelverk. LÄS MER

  7. 5. The Balance between Pro- and Antiinflammatory Molecules in ANCA-Associated Vasculitis

    Författare :Sophie Ohlsson; Njurmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nephrology; Urologi; nefrologi; Urology; monocyte; SLPI; proteinase 3; ANCA; vasculitis; inflammation;

    Sammanfattning : ANCA-associated systemic vasculitis (AASV) is a group of inflammatory disorders, characterized by inflammation and necrosis of blood vessels and frequently granuloma formation. Patients with AASV make autoantibodies, so called ANCA, against proteins present in the granules of neutrophils and monocytes, mainly proteinase 3 (PR3) and myeloperoxidase (MPO). LÄS MER
