    Sammanfattning : Oxidative stress is associated with several diseases, either as a cause or a consequence. Chronic kidney disease (CKD) is one example of a disease in which elevated levels of oxidative stress are frequently reported. LÄS MER

  5. 19. Biocompatibility of synthetic nanomaterials and their applications in gene delivery

    Författare :Jingwen Shi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nanomedicine is the use of nanoscale or nanostructured materials in medicine that due to their structure have unique medical effects. Prominent applications of nanomedicine are the use of nanomaterials for the delivery of drugs and nucleic acids (to correct gene defects). LÄS MER

  7. 20. Characterization of some natural and synthetic materials with silicate structures

    Författare :Edwin Escalera; Farid Akhtar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials; Materialteknik; Engineering Materials;

    Sammanfattning : The present thesis deals with characterization of silicate structures with a determined morphology and structure such as ordered mesoporous silica and layered silicates. Mesoporous silica groups are amorphous solids exhibiting highly ordered pore structures with narrow pore size distributions and large surface areas. LÄS MER
