    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Limulus assay; bioactivity; ergosterol; muramic acid; LPS; organic dust; GC-MS; GC-MSMS; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Inhalation of air-borne microorganisms and components thereof can cause illnesses and diseases. However, lack of specific and sensitive methods for exposure assessment can pose problems in predicting health outcomes. READ MORE

  2. 2. Glass Ionomer Cements with Improved Bioactive and Antibacterial Properties

    Author : Song Chen; Håkan Engqvist; Wei Xia; Jie Zhou; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterial; glass ionomer cement; bioactivity; hydroxyapatite; monetite; calcium silicate;

    Abstract : Dental restorative cements are placed in a harsh oral environment where they are subjected to thermal shock, chemical degradation, and repeating masticatory force. The ideal restorative dental cements should have superior mechanical properties, chemical stability, aesthetic, good handling properties, biocompatibility, antibacterial properties, and preferably bioactivity.

  3. 3. Titanium Dioxide Photocatalysis in Biomaterials Applications

    Author : Yanling Cai; Ken Welch; Maria Strømme; Håkan Engqvist; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; titanium dioxide; photocatalysis; bioactivity; antibacterial effect; metabolic activity assay; biofilm; reactive oxygen species; disinfection kinetics; post-UV;

    Abstract : Despite extensive preventative efforts, the problem of controlling infections associated with biomedical materials persists. Bacteria tend to colonize on biocompatible materials and form biofilms; thus, novel biomaterials with antibacterial properties are of great interest. READ MORE

  4. 4. Bioactive Coatings and Antibacterial Approaches for Titanium Medical Implants

    Author : Oscar Janson; Ken Welch; Pentti Tengvall; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioactivity; antibacterial; titanium; hydrogen peroxide; hydroxyapatite; biomaterial; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : The aim of this thesis was to characterize and manufacture coatings and surfaces with antibacterial properties and retained or enhanced bioactivity and biocompatibility. The aim was also to study the optimal composition and parameters of mixtures for debridement of bacterial biofilms on titanium surfaces. READ MORE

  5. 5. Nutri-medicinal plants used in the management of HIV/AIDS opportunistic infections in western Uganda : documentation, phytochemistry and bioactivity evaluation
