  1. 21. Production of neocartilage tissues using primary chondrocytes

    Författare :Janne Ylärinne; Mikko Lammi; Chengjuan Qu; Mats Brittberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; primary chondrocytes; articular cartilage; tissue engineering; neocartilage; scaffold; scaffold-free; hyaluronan; self-assembling peptide; TGF-β3; glucosamine sulfate; hypoxia; hypertonic medium; glucose;

    Sammanfattning : Hyaline cartilage is a highly specialized tissue, which plays an important role in the articulating joints of an individual. It provides the joints with a nearly frictionless, impact resisting surface to protect the ends of the articulating bones. LÄS MER

  3. 22. Aqueous graphene dispersions for paper packaging

    Författare :Wei Zhao; Anwar Ahniyaz; Abhilash Sugunan; Thomas Gillgren; Johan A. Larsson; Zhi-Bin Zhang; Shi-Li Zhang; Valeria Nicolosi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; Aqueous graphene dispersions; Noncovalent interactions; Composites; Barriers; Inkjet printing; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Sammanfattning : Graphene is widely touted as the thinnest and the most versatile material available. As an atomically thin layer of carbon atoms arranged in a hexagonal configuration, graphene has a combination of technologically important properties, such as thermal and electrical conductivity, mechanical strength, and impermeability to gases.

  4. 23. Regulation of biofilm formation in Salmonella typhimurium and Escherichia coli Nissle 1917

    Författare :Cláudia Monteiro; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Bacteria have the ability to grow in cell communities designated biofilms. This mode of growth is widespread and offers numerous advantages to the bacteria in terms of survival, persistence and propagation. Bacteria have developed different ways of building up a biofilm.

  5. 24. On laser Doppler flowmetry : methods and microvascular applications

    Författare :Torsten Tenland; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A laser Doppler flowmeter for non-invasive microcirculatory blood flow studies has been developed. The tissue under study is illuminated by laser light (helium-neon laser, output power 2 mW) via an optical fibre and the Doppler shift oflight scattered in moving red cells is analysed. LÄS MER

  7. 25. Gas exchange with a reflecting system for inhalational anaesthesia

    Författare :Louise Walther Sturesson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anesthetic conserving device; inhalational anaesthesia; carbon dioxide; Gas exchange;

    Sammanfattning : In order to reduce comsumption of inhalational anaesthetsics during high flow anaesthesia a system open in regard to oxygen, nitogen and nitrous oxide, but closed to inhalational anaesthetics, was developed. This was achieved by a reflecting filter for inhalational anaesthetics made of active carbon. LÄS MER
