  1. 21. Metabolic and Endocrine Response in the Acute Stage of Subarachnoid Hemorrhage

    Författare :Christoffer Nyberg; Elisabeth Ronne Engström; Torbjörn Karlsson; Lars Hillered; Silvana Naredi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid hemorrhage; Energy Expenditure; BNP; Animal Model; Cortisol; Microdialysis; Neurokirurgi; Neurosurgery;

    Sammanfattning : The rupture of an aneurysm in subarachnoid hemorrhage (SAH) is a dramatic event causing a severe impact on the brain and a transient or permanent ischemic condition. Several types of responses to meet the challenges of SAH have been found in the acute phase, including activation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, elevated levels of brain natriuretic peptide (BNP), and disturbances in cerebral and systemic metabolism.

  3. 22. Isolation and characterization of lipid-associated and neurosecretory polypeptides

    Författare :Margareta Stark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Lipid-interacting proteins play important roles in all living organisms. This thesis focuses on isolation and characterization of an enzyme in the triacylglycerol biosynthesis (phosphatidic acid phosphatase, PAP), hydrophobic polypeptides in bile, and polypeptides in cerebrospinal fluid.

  4. 23. Physiological and pathophysiological regulation of ECL-cell activity

    Författare :Maria Lundgren; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacy; toxicology; Pharmacological sciences; pharmacognosy; Gastroenterologi; endothelin; gastrin; ischemia-reperfusion; Physiology; Fysiologi; Gastro-enterology; pancreastatin; histamine; microdialysis; ECL-cell; stomach; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They produce and secrete histamine and chromogranin A-derived peptides in response to circulating gastrin. Mobilized histamine stimulates acid secretion from adjascent parietal cells. LÄS MER

  5. 24. Tumour Biological Factors Characterizing Metastasizing Serotonin-producing Ileocaecal Carcinoids

    Författare :Janet Lynn Cunningham; Eva Tiensuu Janson; Kjell Öberg; Irvin M. Modlin; Uppsala universitet; []
    Nyckelord :Internal medicine; endocrine tumour; midgut carcinoid; serotonin-producing neuroendocrine carcinoma; prognosis; morphology; tachykinin; connective tissue growth factor; islet autoantigen-2; morphology; carcinoid syndrome; Invärtesmedicin;

    Sammanfattning : In this study, metastasizing serotonin-producing ileocaecal carcinoid tumours (MSPCs) were examined for biological characteristics that could be used to define clinically relevant subgroups within this patient population. Possible targets for new treatment options were also explored. LÄS MER

  7. 25. Somatostatin Receptor Expression and Biological Functions in Endocrine Pancreatic Cells

    Författare :Eva Ludvigsen; Stellan Sandler; Eva Tiensuu Janson; Mats Stridsberg; Frank Sundler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; somatostatin; somatostatin receptors; somatostatin analogues; NOD mouse; type 1 diabetes; pancreatic islets; BON-1 cells; Cellbiologi; Cell biology; Cellbiologi;

    Sammanfattning : Type 1 diabetes is resulting from the selective destruction of insulin-producing beta-cells within the pancreatic islets. Somatostatin acts as an inhibitor of hormone secretion through specific receptors (sst1-5). LÄS MER
