1. 6. Magnetic resonance imaging and diffusion tensor imaging after brachial plexus injury and repair : Experimental and clinical study

   Författare :Grainne Bourke; Mikael Wiberg; Lev N. Novikov; Lars Dahlin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brachial Plexus; Magnetic Resonance Imaging; Neonatal; Diffusion Tensor Imaging;

   Sammanfattning : Brachial plexus injuries (BPI) cause permanent upper limb paralysis and serious disability in adults and children. Timely identification of the severity of nerve injury and early appreciation of the inane potential for recovery would revolutionise management. LÄS MER

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

   Författare :Maria Brohlin; Mikael Wiberg; Martin Birchall; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 8. Att gestalta måltider – mise en place, dukning och servering : En metodstudie i servitörens hantverkskunnande

   Författare :Lars Eriksson; Åsa Öström; Gunnar Almevik; Mikael Wiberg; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tidsgeografi; estetik; restaurang; yrkeskunskap; hantverksforskning; metod; tyst kunskap; sinnliga bedömningar; uppmärksamhet;

   Sammanfattning : I restaurangbranschen har rationaliseringar tvingats fram och kunskap efterfrågas i mindre omfattning. Syftet med avhandlingen är därför att utveckla begrepp och pröva metoder för att återge och förmedla procedurer och göranden i hantverk för att därigenom visa vad som är servitörens yrkeskunskap.

5. 9. Striking a balance : Managing collaborative multitasking in computer-supported cooperation

   Författare :Rikard Harr; Victor Kaptelinin; Mikael Wiberg; Oskar Juhlin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer-supported Cooperative Work; articulation work; individual task execution; balance; interruptions; availability; awareness; interaction; information technology; multitasking; task switching; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

   Sammanfattning : This thesis is a collection of six papers and a cover paper reporting an exploration of how to strike a balance between individual task execution and work articulation in Computer-supported Cooperative Work (CSCW). The interest in this theme is motivated by an increased reliance of IT-supported cooperative work arrangements in modern organizations, the fragmented layout of work for multitasking individuals and reports on various forms of overload, increased level of stress and anxiety experienced by workers active in these organizations.

7. 10. Nerve gap repair by the use of artificial conduits and cultured cells

   Författare :Daniel Kalbermatten; Mikael Wiberg; Ulrich Mennen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipose stem cells; cell matrix; fibrin; nerve conduit; nerve gap; Surgery; Kirurgi; kirurgi; Surgery;

   Sammanfattning : Peripheral nerve injuries are often associated with loss of nerve tissue and require autologous nerve grafts to provide a physical substrate for axonal growth. This thesis investigates the use of fibrin as both a tubular conduit to guide nerve regeneration and also as a matrix material to suspend various regenerative cell types within/on poly-3-hydroxybutyrate (PHB) nerve conduits.
