  1. 6. Neuronal types and their specification dynamics in the autonomic nervous system

    Författare :Alessandro Furlan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The autonomic nervous system is formed by a sympathetic and a parasympathetic division that have complementary roles in the maintenance of body homeostasis. Autonomic neurons, also known as visceral motor neurons, are tonically active and innervate virtually every organ in our body. LÄS MER

  3. 7. Secretory and anti-inflammatory actions of some gastro-intestinal hormones in salivary glands

    Författare :Hülya Çevik Aras; Göteborgs universitet; []
    Nyckelord :salivary glands; protein secretion; synthesis; inflammation; β-defensins; myeloperoxidase; cholecystokinin; gastrin; melatonin; nitric oxide; nerve stimulation;

    Sammanfattning : Textbooks generally state that the secretory activity of salivary glands is solely regulated by nerves. This view is challenged in the present Thesis, using the parotid gland of the anaesthetized rat as experimental in vivo model. LÄS MER

  4. 8. Neuronal tracers for fine caliber spinal primary afferents and their response to peripheral nerve injury

    Författare :H Fredrik Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Rat; Primary afferents; Dorsal root ganglion; Peripheral nerve injury; Spinal cord; Isolectin GSA I-B4; Soybean agglutinin; Cholera toxin B subunit; Horseradish peroxidase; Immunohistochemistry; Neuronal tracing;

    Sammanfattning : The isolectin B4 from Griffonia simplicifolia I (B4) and soybean agglutinin from the plant Glycine max (SBA), have been shown to bind to rat small-diameter dorsal root ganglion (DRG) neurons, and to fibers and presumed terminals in laminae I-II of the spinal cord dorsal horn. In the present thesis, these lectins and/or their horseradish peroxidase (HRP) conjugates, have been investigated in the rat with regard to their usefulness as selective neuronal markers of and axonally transported tracers for somatic and/or visceral spinal primary afferents with fine caliber, including unmyelinated, axons.

  5. 9. Heart Rate Variability in Stress-related Fatigue, Adolescent Anxiety and Depression and its Connection to Lifestyle

    Författare :Erik Olsson; Lennart Melin; Ulf Lundberg; Uppsala universitet; []
    Nyckelord :heart rate variability; autonomic nervous system; vagal tone; allostatic load; stress; fatigue; anxiety; depression; continuous performance; attention; cardiovascular risk; lifestyle; physical activity;

    Sammanfattning : Heart rate varies constantly as a consequence of activity in the sympathetic and parasympathetic autonomic nervous systems (SNS and PNS). In short-term recordings, heart rate variability (HRV) is mostly related to the inhibitory activity of the vagal nerves, which are part of the PNS. LÄS MER

  7. 10. On The Innervation of Salivary Glands and Treatment of Dry Mouth - An Experimental and Clinical Study

    Författare :Nina Khosravani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parotid gland; Denervation; Acetylcholine synthesis; Otic ganglion; Auriculo-temporal nerve; Facial nerve; Neuropeptides; Salivary gland hypofunction; Physostigmine;

    Sammanfattning : Detailed knowledge of the innervation of the parotid gland is essential in basic studies on various neuroglandular phenomena as well as in various types of orofacial surgery. The innervation is more complex than usually depicted in Textbooks. LÄS MER
