  1. 11. Cervical Radiculopathy : Studies on Pain Analysis and Treatment

    Författare :Anna MacDowall; Claes Olerud; Helena Brisby; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cervical radiculopahy; Artificial disc replacement; Orthopaedics; Ortopedi;

    Sammanfattning : Background: Knowledge about how to interpret pain-analyzing tools such as the pain drawing test and the visual analog scale (VAS) in cervical spine patients are sparse; hence, they have never been validated for this subgroup of patients. The method of artificial disc replacement (ADR) has been developed as an alternative treatment to fusion surgery after decompression for cervical degenerative disc disease (DDD) with radiculopathy.

  3. 12. Studies of Novel Nanostructures by Cross- sectional Scanning Tunneling Microscopy

    Författare :Lassana Ouattara; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dilute ferromagnetic semiconductors Superlattices; Cross-sectional scanning tunneling microscopy; Semiconductor nanostructures; Fysik; Physics; Epitaxy; Quantum dots; Nanowires;

    Sammanfattning : This thesis presents structural and morphological studies of semiconductor nanostructures, namely quantum dots, nanowires and a dilute ferromagnetic semiconductor. These nanostructures are investigated on the atomic scale using cross-sectional scanning tunneling microscopy (XSTM). LÄS MER

  4. 13. Assessment of 3D movements in the lumbar and cervical spine with a new CT based method

    Författare :Per Svedmark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Numerous methods for measuring segmental motion in spine have been described. However, because of the inaccessibility of the spine and the complexity of segmental movements, most of the noninvasive methods in use today have low accuracy or are unable to detect movements in all three cardinal axes.

  5. 14. Tissue remodelling proteases as prognostic factors in colon and rectal cancer

    Författare :Marcus Langenskiöld; Göteborgs universitet; []
    Nyckelord :extracelluar matrix; survival; staging; colorectal cancer; mucosa; stroma;

    Sammanfattning : Background: Colorectal cancer is the third most common cancer in Sweden and the main treatment is surgery. The TNM classification is the principal staging tool, although insufficient in identifying all patients with poor survival. LÄS MER

  7. 15. The value of artificial disc replacement in cervical radiculopathy

    Författare :Martin Skeppholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background; Artificial disc replacement (ADR) is a motion-preserving implant and a further development of existing surgical implants for the treatment of cervical radiculopathy. Theoretically, an artificial disc could decrease stress on adjacent segment and thereby prevent rapid progression of degenerative changes in surrounding segments. LÄS MER
