  1. 6. Digital Image Analysis of Cells : Applications in 2D, 3D and Time

    Författare :Amalka Pinidiyaarachchi; Carolina Wählby; Ewert Bengtsson; Arvid Lundervold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; microscopy; fluorescent staining; watershed segmentation; sub-cellular localization; point-like signals; wavelets; cell confluence; cytology; color spaces.; Image analysis; Bildanalys;

    Sammanfattning : Light microscopes are essential research tools in biology and medicine. Cell and tissue staining methods have improved immensely over the years and microscopes are now equipped with digital image acquisition capabilities. The image data produced require development of specialized analysis methods. LÄS MER

  3. 7. Desmoid tumors. New aspects on diagnostic procedures, treatment and outcome

    Författare :Mikael Dalén; Göteborgs universitet; []
    Nyckelord :desmoid; fibromatosis; surgery; radiotherapy; chemotherapy; statistics; imaging; studies; cytology; biopsy; pathology;

    Sammanfattning : Desmoid tumor (aggressive fibromatosis) is a rare, benign fibroblastic/myofibroblasticneoplasm that originates from musculoaponeurotic structures. It never metastasizes but locallygrows aggressively and infiltrates surrounding tissues. The treatment of choice has beensurgery. However, local recurrences are frequent. LÄS MER

  4. 8. Gene Expression Studies of Hematologic Malignacies

    Författare :Anna Andersson; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; cancer; onkologi; Cytologi; oncology; Cytology; acute myeloid leukemia; acute lymphoblastic leukemia; normal hematopoietic cells; cDNA microarray; gene expression profiling; hematopoiesis; pediatric leukemia; fusion gene; Pediatrics; Pediatri; Clinical genetics; Klinisk genetik; cancerology; Hematologi; extracellulära vätskor;

    Sammanfattning : The general aim of this thesis was to characterize hematologic malignancies using gene expression profiling in order to obtain an improved classification and to study deregulated transcriptional networks in leukemia. In the first study (Article I), the gene expression profiles of hematologic cell lines were analyzed to investigate whether such cell lines maintain expression profiles that are characteristic of their primary genetic changes.

  5. 9. Studies of radioactive cisplatin (191Pt) for tumour imaging and therapy

    Författare :Johan Areberg; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytology; mice; in vitro; gamma camera; tumour imaging; platinum pharmacokinetics; cisplatin; radioactive; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : A radioactive variant of the cytostatic agent cis-dichlorodiammineplatinum(II), cisplatin, was synthesised from 191PtCl4. The 191Pt-cisplatin was found to be a sterile product of high radionuclide, radiochemical and chemical purity. LÄS MER

  7. 10. Human glandular kallikrein 2 (hK2) in prostate cancer: Clinical and Methodological studies

    Författare :Charlotte Becker; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; screening; prostate cancer; PSA; Human glandular kallikrein; hK2; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : Human glandular kallikrein 2 (hK2) is a predominantly prostate produced protein with many similarities to prostate-specific antigen (PSA). Just like for PSA elevated levels of hK2 can be found in men with protate cancer. We created an assay where hK2 in serum could reliably and with negligible cross-reactivity with PSA, be measured down to 0. LÄS MER
