  1. 6. Calpain-Mediated Apoptosis in Motor Neurons of Adult Mouse Spinal Cord Slices

    Författare :HamidReza Momeni; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Calpain; Djurfysiologi; Animal physiology; Spinal cord; Organ culture; Mouse; Motor neurons; Caspase; Calpain inhibitor; Calpain activity; Apoptosis;

    Sammanfattning : Motor neuron degeneration is a critical phenomenon during spinal cord injuries and some neurodegenerative diseases. However, the mechanisms by which cell death is induced in these neurons are poorly understood. LÄS MER

    Sammanfattning : Packaging DNA into chromatin represses essential DNA-based processes, such as transcription, DNA replication, and repair. To change the accessibility of DNA, cells have evolved a set of enzymes referred to as chromatin remodelers that act on the basic repeat unit of chromatin,  the nucleosome. LÄS MER

  3. 8. Effect of timing training in golf and soccer players : skill, movement organization, and brain activity

    Författare :Marius Sommer; Louise Rönnqvist; Charlotte Häger; Nicola Hodges; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Motor timing; rhythmicity; timing training; golf shot; golf swing; kinematics; precision; variability; coordination; movement dynamics; soccer; fMRI; mirror neurons; action observation; cerebellum; perception - action.; Psychology; psykologi;

    Sammanfattning : Background Although trainers and athletes consider ‘good timing skills’ to be critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Thus, assuming that all motor performances are mediated by an internal timing mechanism, enhanced motor timing is expected to have positive effects on both planning and execution of movement performance, and consequently on complex sports actions as golf or soccer.

  4. 9. The Role of the Cortico-Basal Ganglia-System in Voluntary Movements

    Författare :Martin Tamté; Integrativ neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Electrophysiology; Pharmacology; Motor Systems; Voluntary movements; Philosophy; In vivo; Corticostriatal; Parkinson s disease; Dyskinesia; Levodopa; Multiple Electrode Arrays;

    Sammanfattning : Bodies with multiple limbs and joints have endless possibilities to move around in their surrounding space. How the nervous system controls this amount of degrees of freedom in motor execution is a question under vigorous debate. LÄS MER

  5. 10. Amyotrophic Lateral Sclerosis – A Study in Transgenic Mice

    Författare :Hanna Wootz; Dan Lindholm; Håkan Aldskogius; Christopher Fowler; Uppsala universitet; []
    Nyckelord :Neurosciences; ALS; Caspase; Caspase-12; Cathepsin; Cystatin; ER stress; Motor neuron; Neurodegeneration; Sod1; XIAP; Neurovetenskap;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with an incidence of 1.5-2.7/100000 people/year. Today there is no cure for the disease and only symptomatic treatments are available. LÄS MER
