  1. 1. Silicone obturators and the bacterial flora in symptomatic nasal septal perforations

    Författare :Anna Karin Hulterström; Anders Berglund; Diana Berggren; Åke Davidsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nasal mucosa; perforation; symptomatic; inflammation; Staphylococcus aureus; obturator treatment; medical silicone; wettability;

    Sammanfattning : Background A perforation in the nasal septum can cause symptoms such as bleeding, obstruction, crusts and pain, and can be a challenge to treat. Surgery is the treatment of choice, but disease, size of the perforation, or the patient’s wish may contradict surgery. LÄS MER

  3. 2. Ecology and genetic population structure of Indo-Pacific bottlenose dolphins in East Africa

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymers; cellulose; conjugated polymers; volume changes; plant growth substrates;

    Sammanfattning : Polymers (Greek: poly=many, meros=part) are large molecules made up of many small parts (monomers) in a repetitive way, as a term was introduced for the first time (1833) by the Swedish chemist, Jöns Jakob Berzelius. By the combination of different monomers, the resulting polymer can exhibit various properties, such as biodegradability, photosensitivity and electrical conductivity. LÄS MER
