  1. 6. Characterization of the perturbed differentiation in neuroblastoma, aided by the analysis of normal sympathetic nervous system development

    Författare :Carolina Gestblom; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; development; TrkA; apoptosis; proliferation; sympathetic nervous system; neuronal; paraganglia; neuroblastoma; chromaffin; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Neuroblastoma is a pediatric tumor derived from cells in the sympathetic nervous system. In an attempt to explain the heterogeneous clinical behavior of neuroblastoma tumors, neuroblastomas have been characterized with regard to their degree of sympathetic differentiation. LÄS MER

  2. 7. The emotional motor system and gastrointestinal symptoms

    Författare :Pontus Karling; Lars Agréus; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anxiety; ANS; autonomic nervous system; cortisol; DST; emotional motor system; functional; gastrointestinal symptoms; GSRS-IBS; gut; HADS; heart rate variability; HPA axis; IBS; irritable bowel syndrome; stress; unipolar depression; val158met COMT polymorphism; Gastroenterology; Gastroenterologi;

    Sammanfattning : There is a significant comorbidity between anxiety/depression and functional gastrointestinal syndromes, such as irritable bowel syndrome (IBS) and functional dyspepsia. The pathophysiological link between emotions and the gut is not known. LÄS MER

  3. 8. The Physiology of Chicken Domestication : Involvement of the HPA-axis and the Autonomic Nervous System

    Författare :Magnus Elfwing; Jordi Altimiras; Michael Axelsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Domestication; chickens; HPA-axis; autonomic nervous system; heart rate; allometry;

    Sammanfattning : Domesticering är en urvalsprocess för önskvärda egenskaper hos djur som över tid förändrar deras utseende, beteende och genetik. Några exempel av djur som genomgått denna riktade avel är vargen, mufflon, uroxen, vildsvinet och den röda djungelhönan som vi idag känner som hunden, fåret, kon, grisen och slaktkycklingen. LÄS MER

  4. 9. Sympathetic function in cardiac disorders.Upon cardio-renal sympathetic activity and effects of nitroglycerin in human heart failure

    Författare :Magnus Petersson; Göteborgs universitet; []
    Nyckelord :heart failure; renovascular hypertension; sympathetic nervous system; noradrenaline; mortality; renal circulation; cardiovascular physiology; baroreflex; nitroglycerin;

    Sammanfattning : This study explores pathophysiological mechanisms and prognostic implications of sympathetic activation in patients with atherosclerotic renovascular hypertension (RVH) and with chronic heart failure (CHF). Hitherto, it is unknown whether cardiac sympathetic activation is present in patients with RVH, the presence of which could relate to the increased cardiovascular mortality observed in this disorder.

  5. 10. Zinc-enriched neurons in the spinal cord, cerebellum and peripheral sympathetic system

    Författare :Zhan-You Wang; Göteborgs universitet; []
    Nyckelord :autometallography; axonal transport; confocal laser scanning microscopy; immuno-electron microscopy; immunofluorescence; inhibitory neurons; sympathetic neurons; synaptic vesicles; zinc ions; zinc transporter;

    Sammanfattning : Zinc ions are abundant in the nervous system and are involved in many biological functions. Most zinc is tightly bound to macromolecules, whereas a small fraction of zinc exists in synaptic vesicles of the zinc-enriched (ZEN) neurons, and can be visualized using various histochemical techniques, including autometallography (AMG).
