  2. 21. Growth regulation in sarcomas : studies in vivo and in cell culture

    Author : Avni Abdiu; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Sarcomas are malignant tumors of mesenchymal origin, and can arise in soft-tissue and in bones. It has been suggested that the abnormal growth regulation in sarcoma cells may be due to an autocrine mechanism, in which the cells are stimulated by an endogenous production of growth factors.

  4. 22. Morphologic and genetic features of sarcomas : improving diagnosis and exploring biomarkers

    Author : Yifan Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sarcomas are malignant tumors of soft tissue and bone origin. They are a family of rare but diverse neoplasms which pose clinical challenges due to their heterogeneous properties. READ MORE

  5. 23. Studies of VEGF-B and novel PDGFs in tumorigenesis and angiogenesis

    Author : Hong Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The family of VEGF/PDGF growth factors and their receptors are important regulators of tumorigenesis and angiogenesis. VEGFs have been shown to play important roles in development of both blood and lymphatic vessels by effect on endothelia cells. READ MORE

  6. 24. Mitotic failure and genome stability in benign, premalignant and malignant human tissues

    Author : Rüdiger G Steinbeck; Karolinska Institutet; Karolinska Institutet; []
    Keywords : aneuploidy; CDF; clonal selection; DNA content; image microphotometry; interphase; microsection; nondisjunction; unbalanced telophase;

    Abstract : Mitotic failure may occur throughout the human lifespan. Individual nuclear mistakes will escape detection within the mass of somatic cells. The probability of nondetection increases with progression in development. READ MORE

  7. 25. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

    Author : Mary Adjeiwaah; Tufve Nyholm; Rob HN Tijssen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; Radiotherapy; geometric distortions; patient-induced susceptibilities MR-only; radiofysik; radiation physics;

    Abstract : Magnetic resonance imaging (MRI) utilizes the magnetic properties of tissues to generate image-forming signals. MRI has exquisite soft-tissue contrast and since tumors are mainly soft-tissues, it offers improved delineation of the target volume and nearby organs at risk. READ MORE
