  1. 11. Assessment of tympanic membrane : a study of children with otitis media in general practice

    Författare :Thorbjörn Lundberg; Herbert Sandström; Sten Hellström; Claude Laurent; Magnus Von Unge; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Family Medicine; allmänmedicin; oto-rhino-laryngologi; Oto-Rhino-Laryngology;

    Sammanfattning : Background Acute otitis media (AOM) is a common disease in children and is causing great discomfort and disability worldwide but many areas are underserved regarding skilled professional. Tele-otology offers a promising technique to provide ear health globally. Diagnostic accuracy of AOM has regardless of method been found to be low. LÄS MER

  3. 12. The Human Cochlea and Cochlear Implantation : Morphological Characteristics and Clinical Correlations

    Författare :Nadine Schart-Morén; Helge Rask-Andersen; Elina Mäki-Torkko; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cochlear implantation; micro-CT; synchrotron; facial nerve stimulation; hearing preservation; round window;

    Sammanfattning : The most common sensory deficit in the world is sensorineural hearing loss. Cochlear implantation (CI) can majorly contribute to restore hearing, not only in patients with severe to profound hearing loss, but also in hearing-impaired patients with residual low-frequency hearing.

  4. 13. Musculoskeletal Development in Jawed Vertebrates : Gene function, cis-regulation, and 3D phenotypes in zebrafish

    Författare :Jake Leyhr; Tatjana Haitina; Sophie Sanchez; Per Ahlberg; Chrissy Hammond; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nkx3.2; Gdf5; Mkx; zebrafish; jaw joint; skeleton; fin development; cartilage; tendon; ligament; enhancer; CRISPR Cas9; mutant; microCT; synchrotron; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Sammanfattning : Vertebrate skeletons are an intricate framework of bony and cartilaginous structures that form through carefully orchestrated developmental processes, guided by interacting genetic pathways that regulate cellular differentiation, migration, and tissue morphogenesis. The specific timing and localisation of gene expression shapes the diverse array of skeletal elements, from the flexible cartilages of the embryonic stage to the hardened bones that provide structural support in adulthood, and the joints and connective tissues that articulate the musculoskeletal system.

  5. 14. Image processing methods to study the living hearing organ

    Författare :Miriam von Tiedemann; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In this thesis we are developing image processing methods allowing one to probe the structure and function of the mammalian hearing organ, an intricate cellular assembly with a highly specialized three-dimensional organization. Confocal as well as electron microscopy was used for image acquisition. LÄS MER

  7. 15. The temporomandibular joint : Tomopraphic and CT assesment of its bone demarcations with reference to adjacent organs

    Författare :Jan Ahlqvist; Annika Isberg; Sven-Ola Hietala; Umeå universitet; []
    Nyckelord :Temporomandibular joint; anatomy; tomography; CT; artefacts; odontologi; Odontology;

    Sammanfattning : The wall of the temporal bone separating the temporomandibular joint (TMJ) from surroundings organs, can be very thin and also have development defects. Distortion effects in the radiographic reproduction of these bone walls can result in misinterpretations when exanimating suspected pathologic changes in the region. LÄS MER
