    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tau; top quark; ATLAS; LHC; TILE calorimeter; sensitivity; cross-section; standard model; physics; optimal filtering; energy reconstruction; hadronic tau decay; fysik; Physics;

    Sammanfattning : This thesis presents two studies conducted using the ATLAS detectorat the Large Hadron Collider. The first one is a technical study abouthow out-of-time pile-up affects energy reconstruction using the optimalfiltering 2 algorithm in the TILE calorimeter sub detector. The studyis conducted using a pulse simulator software that is also described. LÄS MER

  4. 3. Diving and the brain

    Författare :Anders Rosén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomarkers; brain; central nervous system; decompression sickness; dive research; diving; neuronal damage; saturation diving; tau protein; venous gas embolism; neurofilament light; glial fibrillary acid protein; tau; VGE;

    Sammanfattning : Abstract Introduction There are reports that long-term diving is associated with cognitive impairments. This raises the question if diving itself is harmful to the brain in the absence of decompression sickness or hypoxia. LÄS MER

  5. 4. Tau fragments: role as biomarkers and in the pathogenesis of Alzheimer's disease and other tauopathies

    Författare :Claudia Cicognola; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tau; fragments; Alzheimer s disease; tauopathy; cerebrospinal fluid;

    Sammanfattning : Abstract Tau protein is physiologically expressed in neurons, where it is involved in microtubule assembly and stability. Tau functions are rigorously regulated by a series of modifications, e.g. phosphorylation and dephosphorylation. LÄS MER

  7. 5. Novel cerebrospinal fluid and blood tau biomarkers in Alzheimer's disease and other neurodegenerative diseases

    Författare :Juan Lantero Rodriguez; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tau; Phosphorylation; Biomarkers; Alzheimer’s disease; CSF; Blood;

    Sammanfattning : Tau is a protein predominantly expressed in neurons in the central nervous system (CNS), where it binds microtubules (MT), playing a major role regulating their dynamics and architecture. Under pathological conditions, tau detaches from MTs, leading to neuronal dysfunction and cell death. LÄS MER
