  1. 16. Functional regulation of the dopaminergic system in vivo : Experimental and clinical studies with positron emission tomography

    Författare :Richard Torstensson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : Positron emission tomography (PET) is a non-invasive imaging technique used to quantitate the kinetics of a radiotracer in such physiological processes as receptor binding and enzyme activity. Radiolabelled L-DOPA has previously been used as a tracer for the dopaminergic system. LÄS MER

  3. 17. In vivo regulation of pancreatic beta cell function

    Författare :Pim Pieter van Krieken; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pancreatic beta cells within the islets of Langerhans contribute to the regulation of glucose homeostasis by secretion of insulin, a hormone that stimulates the uptake of glucose by liver, muscle and fat tissue. In response to variations in insulin demand, the beta cell population can adapt by (1) changing the total beta cell mass, and (2) modulating the functional capacity of individual beta cells. LÄS MER

  4. 18. Gastric gland luminal pressure and mucosal protection : An in vivo study in the anesthetized rat

    Författare :Ingrid Synnerstad; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; acid secretion; bicarbonate; epithelial cell surface pH; gastric gland; muscularismucosa; micropuncture; mucosal blood flow; mucus gel thickness; omeprazole; permeability; prostaglandins; ranitidine; rat; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : The driving force for creation of channels in gastric mucus, for acid and pepsin transport, ismost probably the hydrostatic pressure generated within the gastric gland lumen. The aim ofthis study was to investigate the origin and regulation of the glandular pressure. LÄS MER

  5. 19. Gene regulation by nuclear hormone receptors in vivo

    Författare :Anethe Mansén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The nuclear hormone receptor superfamily contains 49 different members, including those for thyroid hormone, TR? and TR?. These receptors are ligand-modulated transcription factors that activate or repress gene activity. The TR? gene encodes two main splice variants, TR?1 and TR?2. LÄS MER

  7. 20. Fcγ Receptors in the Immune Response

    Författare :Teresita Díaz de Ståhl; Jan van de Winkel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Fc Receptors; IgG Receptors; IgE Receptors; Immune regulation; In vivo animal models; Mouse; Rh prophylaxis; Rheumatoid arthritis; Transgenic knockout; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Circulating immune complexes play an important role in the modulation of antibody responses and in the pathogenesis of immune diseases. This thesis deals with the in vivo regulatory properties of antibodies and their specific Fc receptors. LÄS MER
