  1. 16. Imaging brain aromatase by using PET A way to study anabolic steroid abuse

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Kayo Takahashi; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aromatase; brain; molecular imaging; PET; [11C]Vorozole; amygdala; hypothalamus; anabolic-androgenic steroids; abuse; [18F]Vorozole analogs; MEDICINE Morphology; cell biology; pathology Cell biology Neuroscience; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi Neurovetenskap;

    Abstract : Aromatase is an enzyme that facilitates the conversion of androgens to estrogens and may play a role in mood and mental status. The main theme of this thesis is the imaging of brain aromatase by use of the PET technique. The PET tracer for aromatase, 11C-labeled vorozole (VOZ) was developed and evaluated by with in vitro and in vivo methods. READ MORE

    Abstract : Popular Abstract in Swedish Hjärnskador till följd av skallskador (traumatiska hjärnskador) eller otillräckligt blodflöde (cerebral ischemi) är en av de vanligaste orsakerna till död och invaliditet i västvärlden. De vanligaste orsakerna till traumatiska hjärnskador är fordonsolyckor, fall och våldshandlingar. READ MORE

  3. 18. Inflammation and neuroprotective strategies in the immature brain after hypoxic-ischemic brain injury

    University dissertation from Laboratory for Experimental Brain Research

    Author : Pernilla Svedin; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypoxia-ischemia; LPS; immature; brain; inflammation; NAC; melatonin; G-2mPE; MMP-9; MMP-12;

    Abstract : Perinatal brain injury, as a result of hypoxia-ischemia (HI) or infection/HI, is a major cause of acute mortality and neurological morbidity in infants and children. The mechanisms of perinatal HI are not fully understood, which makes it difficult to find effective treatment. READ MORE

    Abstract : Popular Abstract in Swedish Flertal studier talar för att såväl vaskulär demens som demens av Alzheimers typ är relaterade till blodtrycksnivå tidigare under livet. En studie har visat att redan blodtrycket vid 50- årsåldern är relaterat till kognitiva (intellektuella) funktioner vid 70-års ålder. READ MORE

  5. 20. Segmentation and Visualisation of Human Brain Structures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Roger Hult; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : In this thesis the focus is mainly on the development of segmentation techniques for human brain structures and of the visualisation of such structures. The images of the brain are both anatomical images (magnet resonance imaging (MRI) and autoradigraphy) and functional images that show blood flow (functional magnetic imaging (fMRI), positron emission tomography (PET), and single photon emission tomograpy (SPECT)).
