  3. 2. Nanoparticle-based drug delivery systems for neural interfaces - a novel approach for improved biocompatibility

    Författare :Alexander Dontsios Holmkvist; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Neural interfaces; brain damage injury; Minocycline; Gelatin; Nanoparticles; Drug-delivery systems; Biocompatibility; Tissue responses; immunohistochemistry IHC ; Poly D; L-lactic-co-glycolic acid PLGA ; Hydrophobic ion paring; Emulsification-solvent-diffusion method; Drug release; Microglia activation;

    Sammanfattning : The overall purpose of this thesis was to reduce brain tissue responses around implanted microelectrodes using a pharmacological strategy. One of the main aims was to develop and evaluate drug delivery systems that allow local administration of anti-inflammatory pharmaceutics. LÄS MER

  4. 3. Hydrometallurgical Treatment of Neodymium Magnet Waste

    Författare :Marino Gergoric; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; recycling; rare-earth elements; leaching; Keywords: neodymium magnets; solvent extraction;

    Sammanfattning : Recent decades have seen a considerable increase in the usage of rare-earth elements (REEs) in modern technologies and green energy sources. Recycling of REEs out of end-of-life products and E-scrap has become an alternative to mining them out of primary ores due to their supply risk in some countries and the development towards circular economies.

  5. 4. Bone and Cartilage Regeneration: Wnt Signaling Pathway in Healing

    Författare :Anna Thorfve; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wnt signaling pathway; Osteoarthritis; Bone regeneration; Lithium;

    Sammanfattning : The Wnt signaling pathway plays a central role in bone and cartilage embryonic development, processes that are recapitulated during regeneration. Imbalance in such well conserved and complex system often contributes to numerous diseases, whereas controlled modulation of the Wnt signaling activity is an attractive target e.g. LÄS MER

  7. 5. Tissue engineering in blood vessels

    Författare :Gisela Helenius; Göteborgs universitet; []
    Nyckelord :tissue engineering; vascular graft; endothelial cells; smooth muscle cells; thrombogenicity; mechanical properties; scaffold; bacterial cellulose;

    Sammanfattning : Severely occluded coronary- and peripheral arteries, caused by atherosclerotic plaques, are treated with bypass surgery. Autologous veins are the most commonly used replacement graft. Among the patients that need a vascular bypass, 5-10% lack appropriate replacement veins due to previous surgery of bad quality of the vessels. LÄS MER
