  1. 1. Neuron-glial Interaction in the Developing Peripheral Nervous System

    Författare :Mikael Corell; Åsa Fex Svenningsen; Klas Kullander; Helgi Schöith; Heape Anthony; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Schwann cell; nonmyelinating Schwann cell; myelinating Schwann cell; development; proliferation; differentiation; myelin; neural stem cell; central nervous system; peripheral nervous system; enteric nervous system; N-cadherin; GABA; GAD; GABA B receptor; baclofen; CGP55485; Neuroscience; Neurovetenskap; Neuroscience; Neurovetenskap;

    Sammanfattning : The nervous system, including the brain, is the most sophisticated organ in the mammalian body. In such a complex network, neuron-glial interaction is essential and controls most developmental processes, such as stem cell fate determination, migration, differentiation, synapse formation, ensheathment and myelination.

  3. 2. The nervous system of box jellyfish: A surprisingly complex system in a simple animal

    Författare :Linda Parkefelt; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proliferating cell nuclear antigen; arginine vasotocin; RFamide; immunofluorescence; visual system; nervous system; Tripedalia cystophora; Cnidaria; box jellyfish;

    Sammanfattning : The four surprisingly complex visual sensory organs of cubomedusae, the rhopalia, contain each six eyes of four morphologically different types, two of which are camera-type eyes. This means that the evolutionary basal nervous system of cubomedusae must process the visual signals received from a total of 24 rhopalial eyes. LÄS MER

  4. 3. Cyanide and central nervous system : a study with focus on brain dopamine

    Författare :Gudrun Cassel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CNS; cyanide; dopaminergic system; convulsions; receptor binding; tyrosine hydroxylase; monoamine oxidase; extracellular release; inositol phosphate; GABA; GAD;

    Sammanfattning : The brain is a major target site in acute cyanide intoxication, as indicated by several symptoms and signs. Cyanide inhibits the enzyme cytochrome oxidase. This inhibition causes impaired oxygen utilization in all cells affected, severe metabolic acidosis and inhibited production of energy. LÄS MER

  5. 4. Nasal administration of compounds active in the central nervous system : Exploring the olfactory system

    Författare :Maria Dahlin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Nasal administration; olfactory pathway; cerebrospinal fluid; autoradiography; FARMACI; PHARMACY; FARMACI; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : The nasal administration of drugs offers advantages over administration by intravenous injection. Drugs can be rapidly absorbed through the nasal mucosa, resulting in a rapid onset of action, and also avoiding degradation in the gastrointestinal tract and first-pass metabolism in the liver.

  7. 5. Aspects of the human enteric nervous system : A study of the normal development and of Hirschsprung's disease

    Författare :Tomas Wester; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; enteric nervous system; Hirschsprung s disease; intestinal neuronal dysplasia; neuron density; nitric oxide; bcl-2; interstitial cells of Cajal; c-kit; human; fetal; development; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Thirty patients with Hirschsprung's disease (HD) who underwent Rehbein's anterior resection, using a circular stapler to perform the anastomosis, were evaluated retrospectively. The postoperative complication rate and long-term functional outcome were similar to those reported by other investigators using the same and other techniques. LÄS MER
