    Abstract : Neuroblastoma (NB) is a tumor of the sympathetic nervous system and is the most common extra-cranial tumor of childhood, accounting for 7% of all pediatric malignancies. Despite recent advances in therapeutics, outcome is still fatal for patients with aggressive NB and side-effects of treatment are severe. READ MORE

  4. 2. Cell cycle regulatory proteins and miRNAs in premalignant lesions and breast cancer

    Author : Sofie Björner; Malmö Patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Early diagnosis and reliable prognosis and treatment prediction of breast cancer will ultimately lead to a decreased mortality rate. This can be achieved by identification of prognostic and treatment predictive biomarkers, and by understanding the mechanisms behind early changes in the breast. READ MORE

  5. 3. 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

    Abstract : Background: The highest numbers of HIV-infected women are in sub- Saharan Africa, where the natural progression of HIV disease in the absence of treatment results in death before the onset of invasive cervical cancer. With improved access to treatment, several studies outside West Africa demonstrated an increased risk of pre-invasive cervical lesions among HIV-infected women and the positive impact of treatment on the outcome.
