  2. 1. The Role of HoxB4 in Hematopoiesis

    Author : Ann Brun; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellulära vätskor; Haematology; extracellular fluids; adenovirus; gene transfer; knock out; HOXB4; HOXB3; homeobox genes; hematopoietic stem cells; Transcription factors; hematopoiesis;

    Abstract : HOXB4 is one of 39 members of the homeobox (HOX) family, a family of transcription factors involved in embryonic development. Several HOX transcription factors, including HOXB4, are highly expressed in hematopoietic stem cells (HSCs) but are downregulated upon differentiation towards more mature progeny cells. READ MORE

  4. 2. Head and Neck Cancer: Studies on microvessel density, radiation response and FDG PET

    Author : Eva Brun; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 2-18 fluoro deoxy glucose FDG ; radiotherapy; microvessel density; Head and neck cancer; therapy response; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Abstract : Treatment options of head and neck squamous cell carcinoma (HNSCC) usually include combinations of radiotherapy and surgery, and in some cases addition of chemotherapy. In locally advanced cases cure rates are low. Current prognostic factors cannot foresee the outcome for the individual patient. READ MORE

  6. 4. Manifold learning and representations for image analysis and visualization

    Author : Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Reiner Lenz; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; manifold learning; image analysis; signal processing; diffusion tensor mri; Medical informatics; Medicinsk informatik;

    Abstract : We present a novel method for manifold learning, i.e. identification of the low-dimensional manifold-like structure present in a set of data points in a possibly high-dimensional space. The main idea is derived from the concept of Riemannian normal coordinates. READ MORE

  7. 5. Manifolds in Image Science and Visualization

    Author : Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Roland Wilson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; manifold learning; image analysis; signal processing; diffusion tensor mri; Medical engineering; Medicinsk teknik;

    Abstract : A Riemannian manifold is a mathematical concept that generalizes curved surfaces to higher dimensions, giving a precise meaning to concepts like angle, length, area, volume and curvature. A glimpse of the consequences of a non-flat geometry is given on the sphere, where the shortest path between two points – a geodesic – is along a great circle. READ MORE
