  2. 2. Modulation of Neuronal Functions : the Role of SLC10A4

    Författare :Kalicharan Patra; Klas Kullander; Håkan Aldskogius; Per Svenningsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; acetylcholine; central nervous system; neuromuscular junctions; electrophysiology; monoamine; synaptic transmission; neuromodulation; Neuroscience; Neurovetenskap;

    Sammanfattning : Mental health of a person depends on the correct functioning of the brain. The brain and the spinal cord contain many types of cells, of which one important type are called the neurons. Neurons are special in the way they connect to each other to form large networks. LÄS MER

  3. 3. Development of nicotinic receptor ligands for positron emission tomography - from in vitro to in vivo : Binding studies of neuronal nicotinic acetylcholine receptors using different ³H-, ¹1C- and `6Br - labeled ligands

    Författare :Wiebke Sihver; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; nicotinic acetylcholine receptor; PET-ligand; in vitro; in vivo; Alzheimer s disease; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : Neuronal nicotinic acetylcholine receptors (nAChRs) are involved in central processes, such as cognitive functionand memory, and play a critical role in neuropathological changes in Alzheimer's disease (AD). The in vivocharacterization of nAChRs by positron emission tomography (PET) may increase our understanding of thefunctional implications of these receptors in AD and their early changes during this disease.

  4. 4. Zinc-enriched neurons in the spinal cord, cerebellum and peripheral sympathetic system

    Författare :Zhan-You Wang; Göteborgs universitet; []
    Nyckelord :autometallography; axonal transport; confocal laser scanning microscopy; immuno-electron microscopy; immunofluorescence; inhibitory neurons; sympathetic neurons; synaptic vesicles; zinc ions; zinc transporter;

    Sammanfattning : Zinc ions are abundant in the nervous system and are involved in many biological functions. Most zinc is tightly bound to macromolecules, whereas a small fraction of zinc exists in synaptic vesicles of the zinc-enriched (ZEN) neurons, and can be visualized using various histochemical techniques, including autometallography (AMG).

  5. 5. The human Achilles tendon : innervation and intratendinous production of nerve signal substances - of importance in understanding the processes of Achilles tendinosis

    Författare :Dennis Bjur; Sture Forsgren; Patrik Danielson; Håkan Alfredson; Tomas Movin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon; tendinosis; tendinopathy; nerve signal substances; hälsena; Achillessena; tendinos; tendinopati; Orthopaedics; Ortopedi; anatomi; Human Anatomy;

    Sammanfattning : Tendinopathies are painful tendon conditions of presumably multifactorial genesis. In tendinosis, as in Achilles tendinosis, there is apart from pain also morphological changes which are described as degenerative with no signs of inflammation. The exact mechanisms behind these conditions are still, to a large extent, unknown. LÄS MER
