  1. 1. Intestinal Bypass and Total Parenteral Nutrition: Changes in Gut Function and Morphology

    Författare :Mikael Ekelund; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; Gastroenterologi; Gastro-enterology; Fysiologi; Physiology; total parenteral nutrition; supersensitivity; plasticity; intestinal bypass; interstitial cells of Cajal; goblet cells; eosinophils; adaptation; enteric nervous system;

    Sammanfattning : Abolition of enteral nutrition is sometimes required in severe illness. The primary aim of the present work has been to elucidate possible changes in intestinal morphology and motor function in absence of enteral nutrition. Total absence of enteral nutrition in an isolated intestinal segment was created by bypassing the distal ileum in a rat model. LÄS MER

  3. 2. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

    Författare :Ulf Havelius; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

    Sammanfattning : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.

  4. 3. Neuronal Cell Death and Restoration in the Basal Ganglia: Implications for Huntington's and Parkinson's diseases

    Författare :Oskar Hansson; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; basal ganglia; Parkinson s disease; Huntington s disease; neural transplantation; restoration; NMDA receptor; excitotoxicity; calcium; caspase; neuronal cell death; apoptosis; transgenic mouse; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Huntington's disease (HD) is a hereditary neurodegenerative disorder presenting with chorea, dementia and extensive striatal neuronal death. The mechanism through which the widely expressed mutant huntingtin mediates striatal neurotoxicity is unknown. Excitotoxicity, i.e. LÄS MER

  5. 4. The Enteric Nervous System, Plasticity and Survival

    Författare :Katarina Sandgren; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; Nitric oxide synthase; Neuropeptides; Neuronal survival; Lethal spotted mice; Interstitial cells of Cajal; Hirschsprung s disease; Cell cultures; Enteric nervous system; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The thesis deals with plasticity in terms of neurotransmitter expression and survival of neurons in the adult enteric nervous system (ENS). Several motility disorders have been suggested to originate in developmental defects, neurodegeneration, or insufficient innervation by the ENS. LÄS MER

  7. 5. Physiological roles of amyloid precursor protein in vivo - zebrafish as a model

    Författare :Jasmine Chebli; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloid-beta precursor protein; amyloid precursor protein-b; zebrafish; physiological functions; development; trigeminal ganglia; ependyma; cilia; proteomics; translational adaptation;

    Sammanfattning : Amyloid-beta precursor protein (APP) is an evolutionarily conserved transmembrane protein expressed in many different tissues. APP belongs to a gene family consisting of two other APP-like proteins (APLP1 and APLP2). LÄS MER
