    Författare :Håkan Örlefors; Barbro Eriksson; Mats Bergstrom; Anders Sundin; Karel Pacak; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Neuroendocrine tumor NET ; carcinoid; endocrine pancreatic tumor EPT ; Positron Emission Tomography PET ; serotonin-precursor; 5-hydroxytrytophan 5-HTP ; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Medicin; Medicine;

    Sammanfattning : Neuroendocrine tumors (NET´s) are often characterized by overproduction of peptide hormones. In spite of pronounced clinical symptoms, the tumor lesions can be small and difficult to detect. LÄS MER

  4. 3. Spinal motoneurones and the bulbospinal serotonininergic system in aged rats with behavioral deficits

    Författare :Hans Johnson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :aging; behavior; immunohistochemistry; in situ hybridisation; motoneuron; CGRP; axotorny; GAP-43; neurotrophin receptors; degeneration; axon dystrophy; 5HT TRH; SP; 5HLkA; AADC; serotonintransporter protein; fluoxetine; L-5-HTP;

    Sammanfattning : The expression of neuropeptides, growth-related proteins and neurotrophin receptors were studied in motoneurons of young adult rats and in aged rats with symptoms of neuromuscular incapacities. Also studied were aging-related changes in the descending serotoninergic (5HT) bulbospinal system which constitutes a major afferent pathway to spinal motoneurons. LÄS MER

  5. 4. Positron Emission Tomography and Magnetic Resonance Techniques in Diabetes

    Författare :Lina Carlbom; Håkan Ahlström; Olle Korsgren; Olof Eriksson; Lars Johansson; Tove Grönroos; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; Magnetic resonance imaging; Magnetic resonance spectroscopy; Type 1 diabetes; Type 2 diabetes; PET MR; Pancreas transplantation; Perfusion; Radiology; Radiologi;

    Sammanfattning : In order to further advance the field of diabetes research there is a great need for establishing validated non-invasive quantitative techniques to study the pancreas and other tissues of importance for blood glucose regulation. The general aim of this thesis was to explore magnetic resonance techniques and positron emission tomography as such tools. LÄS MER

  7. 5. Midgut carcinoid tumours - biochemical and therapeutic aspects

    Författare :Gunnel Westberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carcinoid syndrome; valvular heart disease; 5-HT; chromogranins; octreotide; hepatic arterial embolization;

    Sammanfattning : The biology of human midgut carcinoid tumour was studied experimentally in primary cell culture and clinically in patients with the midgut carcinoid syndrome. In cell cultures, tumour cells had a secretory pattern of 5-HTP, 5-HT and 5-HIAA specific for each tumour indicating individual regulation of synthesis/degradation. LÄS MER
