  1. 6. Image Analysis in Support of Computer-Assisted Cervical Cancer Screening

    Författare :Patrik Malm; Ewert Bengtsson; Calum MacAulay; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image analysis; cervical cancer; pap-smear; synthetic images; screening; image processing; cytometry; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Cervical cancer is a disease that annually claims the lives of over a quarter of a million women. A substantial number of these deaths could be prevented if population wide cancer screening, based on the Papanicolaou test, were globally available. The Papanicolaou test involves a visual review of cellular material obtained from the uterine cervix. LÄS MER

    Sammanfattning : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. LÄS MER

  4. 8. Algorithms for Applied Digital Image Cytometry

    Författare :Carolina Wählby; Ewert Bengtsson; Stephen Lockett; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Bildanalys; Image analysis; Bildanalys;

    Sammanfattning : Image analysis can provide genetic as well as protein level information from fluorescence stained fixed or living cells without loosing tissue morphology. Analysis of spatial, spectral, and temporal distribution of fluorescence can reveal important information on the single cell level. LÄS MER

    Sammanfattning : This thesis presents work in digital image cytometry applied to fluorescence microscope images of cultivated cells. Focus has been on the development and compilation of robust image analysis tools, enabling quantitative measurements of various properties of cells and cell structures. LÄS MER

  7. 10. Improvements of the Bromodeoxyuridine-DNA Flow Cytometry Method for the Study of Cell Proliferation

    Författare :Maria C Johansson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; head and neck cancer; [3H]thymidine; energy transfer; cell cycle; xenografted tumours; cultured cells; potential doubling time; labelling index; DNA synthesis time; cell proliferation; growth kinetics; Bromodeoxyuridine; DNA flow cytometry; cancer; onkologi; Cytologi; cancerology; oncology; Cytology;

    Sammanfattning : Potential doubling time (Tpot), DNA synthesis time (TS), and labelling index (LI) are fundamental growth kinetics parameters in clinical and experimental cancer research, which may be of further practical importance regarding prognosis and treatment prediction of cancer. They can be measured by bromodeoxyuridine(BrdUrd)/flow cytometry (FCM) methods, where BrdUrd, an analogue of thymidine, is incorporated into DNA and quantified simultaneously with the DNA content.
