  2. 21. Brain Structure and Function in Adolescents with Atypical Anorexia Nervosa

    Author : Gaia Olivo; Helgi B. Schiöth; Christian Benedict; Jessica Mwinyi; Andreas Jansen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; functional MRI; fMRI; magnetic resonance imaging; neuroimaging; brain imaging; anorexia nervosa; eating disorders; neuroscience; adolescents; Medicinsk vetenskap; Medical Science; Neuroscience; Neurovetenskap;

    Abstract : Atypical anorexia nervosa (AAN) has a high incidence in adolescents, resulting in significant morbidity and mortality. The weight loss is generally less pronounced than that experienced in full-syndrome anorexia nervosa (AN), but the medical consequences can be as severe. READ MORE

    Abstract : It is known that some psychiatric disorders may deteriorate in relation to the menstrual cycle. However, in some conditions, such as premenstrual dysphoric disorder (PMDD), symptomatology is triggered mainly by the variations in ovarian steroid hormones. READ MORE

  5. 23. Preclinical PET imaging of Alzheimer's disease progression

    Author : Xiaotian T. Fang; Stina Syvänen; Dag Sehlin; Lars Lannfelt; Merja Haaparanta-Solin; Uppsala universitet; []

    Abstract : Amyloid PET imaging with [11C]PIB enabled detection of Aβ for the first time in vivo. However, [11C]PIB is a small molecule that binds only the insoluble Aβ plaque. Rather, the soluble Aβ aggregates are considered the cause of Alzheimer’s disease (AD). READ MORE

  6. 24. Aspects of PET-CT in prostate cancer. Protocol optimization, diagnostic accuracy, and dosimetry

    Author : Mimmi Bjöersdorff; Malmö Nuklearmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET-CT; Prostatacancer; [18F]FCH; [18F]PSMA-1007; optimering; diagnostisk noggrannhet; dosimetri; PET-CT; Prostate Cancer; [18F]FCH; [18F]PSMA-1007; Optimization; Diagnostic accuracy; Dosimetric;

    Abstract : The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. READ MORE

  7. 25. Studies of Long-lived Radionuclides in the Environment - with Emphasis on 99Tc, 237Np and Pu Isotopes

    Author : Patric Lindahl; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; atomic ratio; environmental samples; nuclear weapons fallout; Chernobyl fallout; bioindicators; activated carbon; Sellafield; plutonium; neptunium; ICP-MS; technetium;

    Abstract : Studies of the long-lived anthropogenic radionuclides 99Tc, 237Np, 239Pu and 240Pu were performed in marine and terrestrial areas contaminated by different accidental and controlled releases of radioactive materials. The three main sources discussed in this thesis are nuclear weapons tests, nuclear reprocessing plants and the Chernobyl accident. READ MORE
