  1. 11. Pet imaging of two monoaminergic neurotransmitter systems in brain : studies of the norepinephrine transporter and dopamine D[2] receptor

    Författare :Nicholas Seneca; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Positron emission tomography (PET) has been widely used to study non-invasively function of the brain, pathophysiology of disease and aid in the development of new drugs. PET and selective radiolabeled molecules allow imaging of certain critical components of neurotransmission, such as pre-synaptic transporters and post-synaptic receptors in living brain. LÄS MER

  3. 12. Suicide attempt and genes : psychiatric and genetic characteristics of suicide attempters

    Författare :Maj-Liz Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Suicide; Attempted; Mental disorders; Association; Genetic markers; Serotonin; Norepinephrine; Dopamine;

    Sammanfattning : Suicide affects an appreciable number of people in all societies. Finding genes that predispose to suicidal behavior may help to identify individuals at risk and an appropriate counseling and support can be extended to them. The studies of the present thesis focus on suicide attempt. LÄS MER

  4. 13. Catecholaminergic neurotransmission in heart and brain : development of tracers for positron emission tomography

    Författare :Claus Oliver Langer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :PET; Radioligand; Catecholamine; Norepinephrine; Dopamine; Heart; Brain; Metaraminol; Dopamine D2 Receptor;

    Sammanfattning : The catecholamines norepinephrine and its biosynthetic precursor dopamine are two principal neurotransmitters in the human central nervous system (CNS). Moreover, norepinephrine is a major transmitter substance in the peripheral, autonomic nervous system. LÄS MER

  5. 14. Prevention and treatment of acute kidney injury after cardiac surgery

    Författare :Bengt Redfors; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute glomerular filtration rate renal circulation oxygen consumption cardiac surgery mannitol dopamine norepinephrine autoregulation;

    Sammanfattning : Acute kidney injury (AKI) occurs frequently after cardiac surgery and is independently associated with increased mortality. The main cause of AKI in these patients is renal ischemia. LÄS MER

  7. 15. The regulation of renal tubular Na+ transport is dependent on interaction between different hormones

    Författare :Yoshiyuki Ohtomo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Norepinephrine; oc-adrenergic; beta-adrenergic; neuropeptide Y; Na ; K -ATPase activity; C-peptide; ontogeny;

    Sammanfattning : Renal Na+,K+-ATPase (NKA) is of great importance for the regulation of salt metabolism and its activity can be inhibited by several natriuretic hormones. So far, the effect of antinatriuretic factors have been less well studied. LÄS MER
