  1. 21. Statistical assessment of genomic variability in tumours and bacterial communities

    Författare :Anna Rehammar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; somatic mutations; hierarchical Bayesian modelling; cancer genetics; high-throughput sequencing; metagenomics; personalised diagnostics;

    Sammanfattning : Current high-throughput DNA sequencing technologies have the ability to generate large amounts of high-resolution genomic data. The high dimensionality in combination with the substantial levels of technical errors and biological variability typically present in the data make, however, the analysis challenging. LÄS MER

  3. 22. Dosimetry of Radionuclide Therapy with 177Lu-octreotate

    Författare :Mattias Sandström; Hans Lundqvist; Mark Lubberink; Sven-Erik Strand; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 177Lu-octreotate; Absorbed dose; Neuroendocrine tumour; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : In radionuclide therapy it is still common to administer standard activities or to scale administered activity with blunt parameters such as body weight or surface area. This is not ideal because, due to considerable variation in kinetics, large safety margins have to be applied to avoid radiation damage to healthy organs, which causes under-treatment of many patients.

  4. 23. Tumour Biological Factors Characterizing Metastasizing Serotonin-producing Ileocaecal Carcinoids

    Författare :Janet Lynn Cunningham; Eva Tiensuu Janson; Kjell Öberg; Irvin M. Modlin; Uppsala universitet; []
    Nyckelord :Internal medicine; endocrine tumour; midgut carcinoid; serotonin-producing neuroendocrine carcinoma; prognosis; morphology; tachykinin; connective tissue growth factor; islet autoantigen-2; morphology; carcinoid syndrome; Invärtesmedicin;

    Sammanfattning : In this study, metastasizing serotonin-producing ileocaecal carcinoid tumours (MSPCs) were examined for biological characteristics that could be used to define clinically relevant subgroups within this patient population. Possible targets for new treatment options were also explored. LÄS MER

  5. 24. Hypoxia and differentiation in human neuroblastoma cells

    Författare :Helén Nilsson; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ontogeny; embryology human ; Utvecklingsbiologi; teratologi; embryologi människa ; teratology; cytogenetik; Development biology; cytogenetics; Genetik; Genetics; Medicin människa och djur ; HIF; Medicine human and vertebrates ; MYCN; Hypoxia; differentiation; Neuroblastoma;

    Sammanfattning : The childhood tumour neuroblastoma is derived from immature cells of the sympathetic nervous system, which have become arrested at different maturation stages. Neuroblastoma is a malignancy with a high degree of heterogeneity, and there is a correlation between a poor differentiation status and a more aggressive phenotype. LÄS MER

  7. 25. PET/CT with 18F-FDG and 68Ga-DOTATOC in pulmonary carcinoid imaging

    Författare :Natalja Uhlén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: PET/CT, positron emission tomography combined with computed tomography, with 18F-FDG (2-deoxy-2-[18F]fluoro-D-glucose) is well established in oncological imaging. Pulmonary carcinoid tumours may have metabolic activity, making them available for PET/CT imaging with 18F-FDG. LÄS MER
