  1. 6. NO PAIN, STILL GAIN- cross-modality development learning guided by spinal spontaneous activity

    Författare :Alexandra Waldenström Ellervik; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; Neurologi; Neurology; neuropsychology; development; spinal cord; activity-dependent learning and memory; pain; somatosensory; neurophysiology;

    Sammanfattning : Recent studies indicate that experience dependent mechanisms shape the pain system during the development. In view of that painful stimuli are rare during development it is not clear how this is accomplished. LÄS MER

  3. 7. Involvement of vasopressin and oxytocin in the regulation of human uterine activity

    Författare :Margareta Steinwall; Urogynekologi och reproduktionsfarmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; uterine activity; oxytocin mRNA; EP2 agonist; receptors; antagonists; oxytocin; vasopressin; andrologi; reproduktion; sexualitet; reproduction; sexuality; Obstetrik; gynekologi;

    Sammanfattning : Vasopressin and oxytocin seem to have pivotal roles in the pathophysiology of primary dysmenorrhoea and preterm labour. Prostaglandins are also involved in the regulation of uterine activity with different receptors mediating both stimulation and relaxation. LÄS MER

  4. 8. Homochiral crystals for selective synthesis

    Författare :Theonitsa Kokoli; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Absolute asymmetric synthesis; total spontaneous resolution; optical activity; coordination compounds; coordination polymers; photoisomerization; enantioselective sulfide oxidation; single crystal X-ray crystallography; co-crystallization of diastereomers;

    Sammanfattning : Six new coordination compounds were prepared from monodentate sulfide ligands and copper(I) halides and their crystal structures were determined by single-crystal X-ray diffraction. The aim was to prepare coordination polymers that crystallize as conglomerates in order to use them in total spontaneous resolution. LÄS MER

  5. 9. Role of potassium channels in regulating neuronal activity

    Författare :Göran Klement; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Potassium channels; threshold dynamics; trafficking; hERG; SMOCs; excitability;

    Sammanfattning : The firing behaviour of excitable cells is fundamental for the information processing in multicellular organisms, varying from single spikes to different forms of repetitive firing. Of the many regulators, voltage gated potassium channels play a major role. In this thesis some aspects of the potassium channel regulation of firing are explored. LÄS MER

  7. 10. Breathing Pattern and Lung Mechanics during Assisted Ventilation Response of Slowly Adapting Pulmonary Stretch Receptors and Effects on Phrenic Nerve Activity in Cats with Normal and Surfactant Depleted Lungs

    Författare :Richard Sindelar; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; slowly adapting pulmonary stretch receptor; phrenic nerve activity; assisted ventilation; surfactant; breathing pattern; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Sammanfattning : Different modes of assisted ventilation were investigated in cats before and after lung lavage and after instillation of surfactant. The activity of single units of slowly adapting pulmonary stretch receptors (PSRs) in the vagal nerve and the integrated phrenic nerve activity were recorded. LÄS MER
