  1. 16. 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

  3. 17. Direct and endothelium-linked serotonergic control of vascular tone in human uterine and umbilical arteries

    Författare :Caroline Karlsson; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; vascular smooth muscle; uterine artery human ; umbilical artery human ; serotonergic receptor; 5-HT; noradrenaline; endothelium; NPY; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : The serotonergic vascular control was investigated by in vitro pharmacology in the human uterine and umbilical arteries. The localisation of immunoreactive (IR) neuropeptide Y (NPY) and the influence of NPY on the adrenergic vascular effects in the human uterine artery were also studied. LÄS MER

  4. 18. Atrial Fibrillation. Modulation of the atrial fibrillatory frequency. A non-invasive approach

    Författare :Carl Meurling; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elektrofysiologi; Förmaksflimmer; arytmi; Cardiovascular system; Kardiovaskulära systemet; non-invasiv;

    Sammanfattning : Aim: To non-invasively detect and explore the changes in atrial fibrillatory cycle length (i.e. changes in the atrial refractory period) in humans with chronic atrial fibrillation (CAF) following autonomic modulation and pharmacological intervention. LÄS MER

  5. 19. Vascular Effects of P2 Receptors. Changes in Congestive Heart Failure

    Författare :Malin Malmsjö; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; congestive heart failure; pyrimidine; purine; P2 receptor; vasodilatation; vasoconstriction; hyperpolarisation; EDHF; NO; Vascular; endothelium; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Extracellular nucleotides induce dilatation and constriction of blood vessels by activation of P2 receptors. In this thesis the vasomotor effects of P2 receptor activation were studied in the rat mesenteric artery, and their changes in congestive heart failure (CHF) were evaluated using in vitro pharmacology, electrophysiology and competitive RT-PCR.

  7. 20. The Biophysics of Na+,K+-ATPase in neuronal health and disease

    Författare :Evgeny E. Akkuratov; Hjalmar Brismar; Anita Aperia; Stefan Wennmalm; Poul Nissen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Na ; K -ATPase; NMDA receptor; ouabain; phosphoproteome; oligomerization; rapid-onset dystonia-parkinsonism; Biologisk fysik; Biological Physics;

    Sammanfattning : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. LÄS MER
