    Sammanfattning : Purified bacterial cell wall components peptidoglycan and teichoic acid were isolated from staphylococcal species S. aureus and/or S. epidermidis and tested for their ability to induce cytokine release from plastic-adherent human monocytes. LÄS MER

  5. 4. Structural Insights into Botulinum Neurotoxins and the ALFA-tag System : Structural and Functional Studies of Proteins Related to the Botulinum Neurotoxins and Design of a Novel Epitope Tag

    Författare :Markel Martínez-Carranza; Pål Stenmark; Thomas Binz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; botulinum neurotoxin; Biochemistry; biokemi;

    Sammanfattning : This thesis is divided into two sections; the first part describes our work in the field of botulinum neurotoxins (presented in papers I, II, III, and manuscript IV) and the second part summarizes our work involving the design of a new biochemical tool (presented in paper V).Botulinum neurotoxins (BoNTs) produced by the anaerobic bacterium Clostridium botulinum are the most poisonous substances known to date.

  7. 5. Long-term properties of polyethylene films : efficiency of a natural antioxidant

    Författare :Clara Strandberg; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer Technology; alfa-tocopherol; Polyethylene PE ; Thermal aging; Infrared Spectroscopy FT-IR ; Chemiluminescence CL ; Solid-phase microextraction SPME ; Chemistry; Kemi;

    Sammanfattning : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. LÄS MER
