  1. 21. Mass spectrometry for comparative proteomics of degenerative and regenerative processes in the brain

    Författare :Carina Sihlbom; Göteborgs universitet; []
    Nyckelord :glycoproteomics; quantitative proteomics; glycoprotein; protein quantification; glycosylation; Fourier transform ion cyclotron mass spectrometry; cerebrospinal fluid; Alzheimer s disease; neurodegeneration; neuroregeneration; hippocampus; astrocytes; brain injury; 14-3-3 protein; isoform;

    Sammanfattning : Biological processes involve changes at the protein level. Proteomics aims to determine protein changes from a normal state, to measure for instance recovery or disease progression. Mass spectrometry is the most important tool for identification of proteins and determination of post-translational modifications such as glycosylation. LÄS MER

  2. 22. Infrared Laser Stimulation of Cerebral Cortex Cells - Aspects of Heating and Cellular Responses

    Författare :Rickard Liljemalm; Tobias Nyberg; Hans von Holst; Claus-Peter Richter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; laser; modeling; heating; infrared neural stimulation; astrocytes; neurons; damage;

    Sammanfattning : The research of functional stimulation of neural tissue is of great interest within the field of clinical neuroscience to further develop new neural prosthetics. A technique which has gained increased interest during the last couple of years is the stimulation of nervous tissue using infrared laser light. LÄS MER

  3. 23. Using patient-derived cell models to investigate the role of misfolded SOD1 in ALS

    Författare :Elin Forsgren; Jonathan Gilthorpe; Stefan Marklund; Peter Andersen; Thomas Brännström; Ulrika Nordström; Séverine Boillée; Umeå universitet; []
    Nyckelord :ALS; SOD1; patient-derived models; induced pluripotent stem cells; motor neurons; astrocytes; 20S proteasome low oxygen tension; misfolded SOD1; Neurology; neurologi;

    Sammanfattning : Protein misfolding and aggregation underlie several neurodegenerative proteinopathies including amyotrophic lateral sclerosis (ALS). Superoxide dismutase 1 (SOD1) was the first gene found to be associated with familial ALS. LÄS MER

  4. 24. Alzheimer Aβ peptides induce dysregulation of C/EBP and NF-кB in glial cells

    Författare :Malin Samuelsson; Kerstin Iverfeldt; Piet Eikelenboom; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; amyloid-β; astrocytes; C EBP; glia; microglia; neuroinflammation; NF-кB; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

    Sammanfattning : Inflammation is believed to contribute to neurodegeneration in Alzheimer’s disease (AD). AD in turn is believed to be a consequence of accumulated amyloid-β (Aβ) peptides, that subsequently form senile plaques, due to imbalance between production and clearance of Aβ. LÄS MER

  5. 25. Cellular Reactions and Behavioral Changes in Focal and Diffuse Traumatic Brain Injury : A Study in the Rat and Mouse

    Författare :Sara Ekmark Lewén; Lars Hillered; Niklas Marklund; Anders Lewén; Mårten Risling; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Astrocytes; Inflammatory response; Multivariate concentric square field test; Morris water maze; Exploratory behavior; Risk taking; Functional outcome.; Neurosurgery; Neurokirurgi;

    Sammanfattning : Traumatic brain injury (TBI) is a severe condition and a major cause of death and disability. There is no pharmacological treatment available in clinical practice today and knowledge of brain injury mechanisms is of importance for development of neuroprotective drugs. LÄS MER
