  1. 1. Long-term Properties of Sustainable Polymeric Materials : Mechanical Recycling and Use of Renewable Resources

    Författare :Emma Strömberg; Sigbritt Karlsson; Amparo Ribes-Greus; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable materials; mechanical recycling; polyolefin; reprocessing; accelerated ageing; chromatography; biofilm; microenvironment chamber; environmental degradation; biocomposite; nanocomposite; Polymer chemistry; Polymerkemi;

    Sammanfattning : New strategies for management of the accumulating amounts of plastic waste are required, to achieve a sustainable development in terms of material production and use. After service life, the materials should be recovered and recycled efficiently to provide a valuable resource for future applications. LÄS MER

  2. 2. BMP implants in bone formation. Studies in rabbits and rats

    Författare :Charlotte Jeppsson; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ortopedi; traumatologi; graft resorption.; Kirurgi; Surgery; orthopaedics; traumatology; bone formation; bone graft; hydroxyapatite; collagen; bisphosphonate; rat; rabbit; titanium chamber; BMP; TGF-ß;

    Sammanfattning : Bone morphogenic proteins, BMPs, are a group endogenous proteins that are highly conserved through evolution. The amino acid sequences of about 15 different BMPs are now known and recombinant human BMPs are commercially available. Implantation of an individual BMP protein is sufficient to induce bone formation even at a subcutaneous site. LÄS MER

  3. 3. Treatment of Skin Wounds with Cell Transplantation and Gene Transfer

    Författare :Tor Svensjö; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pigs; gene regulation; cell culture; fibroblasts; keratinocytes; wound healing; skin; gene transfer; Transplantation; gene therapy; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Background: A large number of different wound coverings have been used in order to improve the wound microenvironment, and thus accelerate repair. Since almost two centuries, clinicians and researchers have developed techniques for skin transplantation. LÄS MER

  4. 4. In vivo imaging of islet cells and islet revascularization

    Författare :Daniel Nyqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Glucose homeostasis depends on the release of insulin from the pancreatic beta-cell. Impaired insulin release is a hallmark of diabetes mellitus. LÄS MER

  5. 5. Studies of cell migration and matrix protease production in human lung cancer cell lines

    Författare :Cecilia G Bredin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Lung cancer; extracellular matrix; growth factors; matrix metalloproteases; integrins; migration; invasion;

    Sammanfattning : Metastatic spread in cancer is a complex multistep process involving continuous, sequential interactions between tumour cells and their respective microenvironment. Invasiveness per se has not been studied in this thesis, only some of its major components, such as cell migration and matrix protease production. LÄS MER
