  1. 1. Vasodilator actions of EDHF and anandamide

    Författare :David Andersson; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vanilloid receptors; afferent neurons; anandamide; cannabinoids; potassium channels; hyperpolarization; vasodilation; Vascular endothelium; arteries; airways; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : Vasodilator responses to endothelium-derived hyperpolarizing factor (EDHF) and anandamide in isolated arteries were investigated. A combination of the potassium channel blockers charybdotoxin and apamin inhibits EDHF-mediated relaxations. LÄS MER

  3. 2. Neuropeptides, sensory neurons and pain modulation

    Författare :Pablo R Brumovsky; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In the present thesis work we have analyzed the expression, regulation and function of two neuropeptides: galanin and neuropeptide tyrosine (NPY). Their associated receptors, galanin receptor-1 and -2 (GaIR1, -R2) and NPY Y1- and Y2R, were also studied. LÄS MER

  4. 3. Neural Control of Movement : Motor Neuron Subtypes, Proprioception and Recurrent Inhibition

    Författare :Anders Enjin; Klas Kullander; Samuel L. Pfaff; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; motor neuron; proprioception; recurrent inhibition; molecular marker; Ia afferent; development; transgenic mice; Renshaw cell; Neurobiology; Neurobiologi; Neuroscience; Neurovetenskap;

    Sammanfattning : Movement is central for life, and all animals depend on accurate regulation of movement for purposeful behavior. There is great diversity of movements, ranging between simple and vital breathing movements to minute and subtle movements of the face used to communicate emotions. LÄS MER

  5. 4. Structure and function of trigeminal primary sensory neurons after peripheral nerve injury

    Författare :Ulf Bongenhielm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ankyrinG; chronic constriction injury; electron microscopy; electrophysiology; hyperexcitability; immunocytochemistry; inferior alveolar nerve; in situ hybridisation; nerve injury; neuroma; SNS PN3; sodium channel; trigeminal ganglion;

    Sammanfattning : Iatrogenic injuries to branches of the trigeminal nerve are common during surgical procedures in the jaws and teeth, and as the repercussion of facial fractures or certain pathologies. A portion of these patients are left with disturbed sensory functions, and some with unpleasant abnormal sensations, including pain. LÄS MER

  7. 5. Getting to know Trioza apicalis (Homoptera: Psylloidea) – a Specialist Host-Alternating Insect with a Tiny Olfactory System

    Författare :Lina Kristoffersen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; Djurs anatomi och morfologi; Entomologi; plant parasitology; Entomology; Ekologi; Ecology; glomeruli; antennal lobe; olfactory receptor neurons electrophysiology; antennae; behaviour; olfaction; Sternorrhyncha; psyllid; Ryggradslösa djurs fysiologi; animal morphology; Animal anatomy; växtparasitologi;

    Sammanfattning : This thesis comprises ecological, morphological and physiological studies of the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) with particular focus on olfaction. Data from inventories of winter habitats suggest that T. apicalis prefer Picea abies over Pinus sylvestris and Juniperus communis as winter hosts. LÄS MER
