  2. 6. The Human Vestibular Aqueduct, Endolymphatic Duct and Sac : A Morphological Study Using Micro-CT, Super Resolution Immunohistochemistry and Synchrotron Phase Contrast Imaging

    Author : Charlotta Kämpfe Nordström; Helge Rask-Andersen; Göran Laurell; Claes Möller; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endolymphatic sac; endolymphatic duct; vestibular aqueduct; Meniere s disease; LVAS; micro-CT; synchrotron phase contrast imaging; Medicinsk vetenskap; Medical Science;

    Abstract : The inner ear lies sheltered in the temporal bone and consists of basically three parts: the cochlea (the hearing organ), the vestibular (the balance organ), and the endolymphatic duct (ED) and endolymphatic sac (ES). The ES and ED are located in a bony canal, the vestibular aqueduct (VA), located on the medial side of the vestibule. READ MORE

  4. 7. 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. 8. Aerosol Metal Nanoparticles and their Role in Particle-Assisted Growth of III–V Nanowires

    Author : Robert Hallberg; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerosol formation; III–V semiconductor materials; catalyst particles; Palladium nanoparticles; Gold nanoparticles; Spark discharge generation; MOVPE; MOCVD; Transmission electron microscopy TEM ; Phase stability; Nanoparticle deposition; Nanoparticle generation; nanoparticles characterization; Nanowire NW ; Nanowire growth;

    Abstract : Semiconductor nanowires have properties that make them potentially useful for applications in future electronic, photovoltaic, and optoelectronic devices. A powerful nanowire fabrication technique is the use of a nanoparticle as a preferential nucleation site, from which a nanowire grows. READ MORE

  6. 9. The enterocyte in small intestinal adaption : an experimental and clinicopathological study with special reference to the ultrastructure of the brush border

    Author : Roger Stenling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scanning electron microscopy; transmission electron microscopy; stereology;

    Abstract : The small intestine mucosa is known to be able to adapt itself to several kinds of both physiological and pathological conditions. The adaptive patterns of the structure of the enterocytes, particularly their apical surface (brush border), were studied in three models: (1) in rats, subjected to antrectomy or antral exclusion, combined with gastroduodenostomy and gastrojejunostomy; (2) in rats with alloxan dia­betes; (3) in children with coeliac disease; a) in its active phase; b) after long-term treatment with gluten-free diets; c) after long-term challenge with dietary gluten following treatment; d) after short-term elimination of dietary gluten.

  7. 10. Numerical and experimental aspect of coherent lensless imaging

    Author : Erik Malm; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent diffractive imaging; Holography; Phase retrieval; Diffraction; Inverse scattering; XUV light; non-rigid image registration; Fysicumarkivet A:2021:Malm;

    Abstract : This thesis is devoted to the understanding, application, and extension of coherent lensless imaging methods for microscopy purposes. Particular attention is given to the Fourier transform holography and coherent diffractive imaging methods. READ MORE
