  2. 1. High-resolution biomedical phase-contrast tomography

    Author : William Twengström; Hans Hertz; Anna Burvall; Marco Stampanoni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; x-ray; x-ray imaging; biomedical; phase contrast; tomography; zebrafish; coronary artery; virtual histology; ring artifacts; phase retrieval; mummy; Fysik; Physics;

    Abstract : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. READ MORE

  4. 2. Virtual histology by laboratory x-ray phase-contrast tomography

    Author : Jenny Romell; Hans Hertz; Anna Burvall; Julia Herzen; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Abstract : Detailed imaging of biological samples is central to different fields of research, as well as for clinical pathology. Classical histology, using light- orelectron microscopy, can generate high-resolution images but is destructive and only gives two-dimensional information. READ MORE

  5. 3. Genetic and molecular regulation of epithelial tube morphogenesis

    Author : Anna Tonning; Göteborgs universitet; []
    Keywords : epithelial tube morphogenesis; trachea; Drosophila; chitin; chitin synthase; apical extracellular matrix; paracellular diffusion barrier; tube expansion; septate junctions;

    Abstract : Networks of epithelial tubes, such as the vertebrate lung, kidney and vascular system, enable transport of gases and nutrients to all tissues in the body. These tubes are built up by a single layer of polarized epithelial cells, with the apical membrane facing the lumen. READ MORE

  6. 4. Microbial Metagenomics : A Tale of the Dead and the Living

    Author : Katarzyna Zaremba-Niedźwiedzka; Siv G.E. Andersson; Jeroen Raes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; single-cell genomics; single cell; fossil metagenome; freshwater metagenome; LD12;

    Abstract : It is a microbial world we live in: microbes outnumber other organisms by several orders of magnitude, and they have great importance for the environment. However, environmental microbes are notoriously difficult to grow in the laboratory, and using culture independent techniques is necessary to expand our view. READ MORE
