  1. 16. Analysis of basic motor behaviors in quadrupeds

    Författare :Manideep Gupta Vemula; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Ability to perform locomotion in different directions and maintain upright body posture is crucial for normal life. At present, mice, which allows employing genetic approaches, are widely used in studying the locomotor system. In these investigations different experimental setups are used to evoke locomotion.

  2. 17. Amyotrophic lateral sclerosis (ALS) associated with superoxide dismutase 1 (SOD1) mutations in British Columbia, Canada : clinical, neurophysiological and neuropathological features

    Författare :Heather G. Stewart; Hiroshi Mitsumoto; Umeå universitet; []
    Nyckelord :ALS; SOD1; complete penetrance; incomplete penetrance; mis-diagnosis; upper motor neuron; clinical neurophysiology; transcranial magnetic stimulation; peristimulus time histogram; corticospinal pathway; cortical inhibition; cortical hyper-excitability;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by loss of motor neurons and their supporting cells in the brain, brainstem and spinal cord, resulting in muscle paresis and paralysis including the bulbar (speech, chewing, swallowing) and respiratory muscles. The average age at onset is 55 years, and death due to respiratory failure occurs 2-5 years after symptom onset in ~ 85% of cases. LÄS MER

  3. 18. A Muscle Perspective on the Pathophysiology of Amyotrophic Lateral Sclerosis : Differences between extraocular and limb muscles

    Författare :Vahid M. Harandi; Jingxia Liu; Fatima Pedrosa Domellöf; Per Stål; Fawzi Kadi; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuromuscular junctions; Extraocular muscles; Skeletal muscle; Neurotrophic factor; Wnt; Motor neuron disease; Amyotrophic lateral sclerosis; SOD1G93A mice; molekylärbiologi; Molecular Biology;

    Sammanfattning : Background: Amyotrophic lateral sclerosis (ALS) is a late-onset progressive neurodegenerative disorder. ALS has been traditionally believed to be primarily a motor neuron disease. LÄS MER

  4. 19. Structural investigation of SOD1 aggregates in ALS : identification of prion strains using anti-peptide antibodies

    Författare :Johan Bergh; Thomas Brännström; Stefan L. Marklund; Peter M. Andersen; Joakim Bergström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; SOD1; prion; motor neuron disease; neurodegeneration; strain; seeding; protein aggregation; transgenic mice; peptide antibodies; Neurology; neurologi;

    Sammanfattning : Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative syndrome characterized by progressive degeneration of motor neurons that result in muscle wasting. The symptoms advance gradually to paralysis and eventually death. Most patients suffer from sporadic ALS (sALS) but 10% report a familial predisposition. LÄS MER

  5. 20. Metabolomics studies of ALS : a multivariate search for clues about a devastating disease

    Författare :Anna Wuolikainen; Peter M Andersen; Henrik Antti; Stefan L Marklund; Thomas Moritz; Thomas Hankemeier; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyotrophic lateral sclerosis ALS ; motor neuron disease; Lou Gehrig’s disease; human disease; CSF; biomarkers; metabolomics; metabonomics; chemometrics; design of experiments; multivariate analysis.; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS), also known as Charcot’s disease, motor neuron disease (MND) and Lou Gehrig’s disease, is a deadly, adult-onset neurodegenerative disorder characterized by progressive loss of upper and lower motor neurons, resulting in evolving paresis of the linked muscles. ALS is defined by classical features of the disease, but may present as a wide spectrum of phenotypes. LÄS MER
