  2. 1. Magnetic resonance imaging in breast diagnosis

    Author : Maria Kristoffersen Wiberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MRI; breast; triple diagnosis; FNAB; size; scintimammography.;

    Abstract : MRI of the breast has, since the introduction of gadolinium contrast agents, been increasingly used in breast investigations. MRI has been found to have a high sensitivity but a low specificity in cancer detection. The aim of this thesis was to study and establish the role of MRI in the clinical diagnosis of breast lesions.

  4. 2. The EU Services Directive – Law or Simply Policy?

    Author : Maria Wiberg; Jane Reichel; Antonina Bakardjieva Engelbrekt; Ulla Neergaard; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Services Directive; free movement of services; internal market; regulatory autonomy; new governance;

    Abstract : The balance between the regulatory autonomy of the Member State of the European Union and the requirements of harmonisation as set out in the EU Services Directive (2006/123/EC) is the subject of this work. The overall effects of the free movement of services on national regulatory autonomy as prescribed by the Services Directive is to a great degree dependent upon whether this directive is perceived of as a traditional directive or instead, as a governance instrument to control and steer the actions of the Member States.

  5. 3. Mesenchymal stem cells for repair of the peripheral and central nervous system

    Author : Maria Brohlin; Mikael Wiberg; Martin Birchall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone marrow-derived stromal cells; Schwann cells; Peripheral nerve injury; Spinal cord injury; Neurotransplantation; anatomi; Human Anatomy; cell research; cellforskning;

    Abstract : Bone marrow-derived mesenchymal stem cells (MSC) have been shown to provide neuroprotection after transplantation into the injured nervous system. The present thesis investigates whether adult human and rat MSC differentiated along a Schwann cell lineage could increase their expression of neurotrophic factors and promote regeneration after transplantation into the injured peripheral nerve and spinal cord.

  6. 4. Schwann cells and mesenchymal stem cells as promoter of peripheral nerve regeneration

    Author : Maria Cristina Mantovani; Mikael Wiberg; Giorgio Terenghi; Susan Shawcross; Lev Novikov; Liudmila Novikova; John W Haycock; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve regeneration; Schwann cell; adult stem cell; myelin; senescence;

    Abstract : The transplantation of primary Schwann cells (SC) has been shown to improve nerve regeneration. However, to monitor the survival of transplanted cells within the host, a stable labelling method is required. READ MORE

  7. 5. Optimizing stem cells for reconstructive surgery

    Author : Anne Therese Lauvrud; Paul J. Kingham; Rebecca Wiberg; Peyman Kelk; Maria Brohlin; Susanna Kauhanen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipose tissue-derived stem cells; liposuction; oncological safety; xenofree growth medium; Human Anatomy; anatomi;

    Abstract : Fat grafting has become an established method in plastic surgery for treating soft tissue defects. The results for survival of the fat being transplanted is unpredictable and supplementation of the graft with the Stromal Vascular Fraction (SVF) or cultures Adipose tissue-derived stem cells (ASCs) can enhance graft viability.
