    Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER

  3. 2. Repair and Reconstruction of Peripheral Nerve Injuries. Treatment with G-CSF and Stromal Vascular Fraction

    Författare :Hanna Frost; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve injuries; nerve regeneration; reconstructive surgical procedures; diabetes mellitus; rat sciatic nerve; granulocyte colony-stimulating factor; stromal vascular fraction; electrospinning; rats; Schwann cells;

    Sammanfattning : While surgery is a cornerstone in treatment of peripheral nerve injuries, it is not a comprehensive approach, and outcome is unsatisfactory, especially sensory function. The present aim was to translate recent findings about stem- and progenitor cells to improve regenerative outcome, where the cells have to be autologous, available within the same surgical procedure, and minimally manipulated.

  4. 3. Effects of inflammatory mediators on human osteoblasts

    Författare :Anders Frost; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : Inflammatory mediators produced in or adjacent to bone have implications on bone and may induce both osteolysis and/or osteosclerosis. Inflammatory cytokines mediate these effects by acting either directly or indirectly on the bone cells. LÄS MER

  7. 5. Hemodilution with dextran: Effects on blood flow and thrombus formation. An experimental study in the rabbit

    Författare :Lieselotte Frost-Arner; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; Hypertonic saline-dextran; Desmopressin; Heparin; Dextran; Rabbit; Synthetic vascular grafts; Blood flow; Hemodilution; Thrombus formation; Kirurgi; ortopedi; traumatologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Microvascular surgery enables free tissue flaps to cover tissue defects, e.g. after trauma and malignancies. Although major improvements in techniques have been made, problems with poor tissue circulation and thrombus formation still exist. LÄS MER
