  1. 16. Peripheral Hypoglycaemic Neuropathy in Type 1 Diabetic Rats : Morphologic and Metabolic Studies

    Författare :Reza Jamali; Simin Mohseni; Claes Hildebrand; Håkan Aldskugius; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes Mellitu; Hypoglycaemia; Neuropathy; Morphology; Microdialysis; Glucose level; Neurobiology; Neurobiologi;

    Sammanfattning : Hyperglycaemia caused by insulin deficiency is believed to play a major role in the de-velopment of neuropathy in diabetic patients. The clinical and pathological features of diabetic neuropathy vary considerably, although sensory and autonomic dysfunctions are the most common characteristics. LÄS MER

  3. 17. The Human Spiral Ganglion

    Författare :Sven Tylstedt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. LÄS MER

  4. 18. Methodological aspects and usefulness of Quantitative Sensory Testing in early small fiber polyneuropathy : a clinical study in Swedish hereditary transthyretin amyloidosis patients

    Författare :Victoria Heldestad; Erik Nordh; Ole Suhr; Göran Solders; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloidosis; cold thresholds; heart rate variability; method-of-limits; quantitative sensory testing; transthyretine; warm thresholds; Clinical Neurophysiology; klinisk neurofysiologi;

    Sammanfattning : Generalised polyneuropathy (PNP) is a common cause to neurological impairment, and may be an early symptom of a severe systemic disease. One such illness is hereditary transthyretin (TTR) amyloidosis (ATTR), a progressive fatal disorder caused by a mutation on the TTR gene. LÄS MER

  5. 19. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference

    Författare :Karin Rylander; Göteborgs universitet; []
    Nyckelord :CT afferent; thin fibre; autonomic; insula; fMRI;

    Sammanfattning : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. LÄS MER

  7. 20. Distribution and function of TRP ion channels in primary sensory neurons

    Författare :Helena Sturesson; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurofysiologi; neuropsykologi; histokemi; cytokemi; vävnadskultur; Neurology; neuropsychology; neurophysiology; Neurologi; tissue culture; histochemistry; cytochemistry; Histology; Skin; Immunohistochemistry; Cannabinoid receptor 1 CB1 ; Pain; Primary sensory neurons; TRP ion channels; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Histologi;

    Sammanfattning : It is frequently argued that cannabinoids exert part of their analgesic and anti-inflammatory effects via activation of the cannabinoid CB1 receptor located on TRPV1-expressing primary sensory nerve fibres in peripheral tissues. However, we find no evidence of CB1 receptor immunoreactivity on nerve fibres in rat or mouse hindpaw skin and mesenteric artery. LÄS MER
