  1. 16. Influence of host and bacterial factors during Neisseria meningitidis colonization

    Författare :Sara Sigurlásdóttir; Ann-Beth Jonsson; Ute Römling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Colonization; Host-bacteria interactions; Lactate; Biofilms; Polynucleotide phosphorylase; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The human-restricted pathogen Neisseria meningitidis is a major cause of bacterial meningitis and sepsis worldwide. Colonization of the mucosal layer in the upper respiratory tract is essential to establish an asymptomatic carrier state and invasive disease. N. LÄS MER

  3. 17. Molecular studies of Neisseria : host cell interactions

    Författare :Anne Rytkönen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The Neisseria family includes many non-pathogenic species but also two strict human pathogens; Neisseria gonorrhoeae and Neisseria meningitidis. Both organisms colonise mucosal surfaces and may cause disseminated infections upon passage of the epithelial barrier. LÄS MER

  4. 18. QCM-based sensing using biological and biomimetic interfaces

    Författare :Louise Elmlund; Ian Nicholls; Teodor Aastrup; Jesper Wiklander; Kristina Nilsson-Ekdahl; Håkan Andersson; Susanne Wikman; Alessandra Maria Bossi; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quartz crystal microbalance; molecularly imprinted polymers; phage display; interactions; artificial receptors; recognition; selectivity; Kemi; Chemistry;

    Sammanfattning : The objective of this thesis was to explore novel approaches for studying molecular recognition at biological and biomimetic surfaces using the quartz crystal microbalance (QCM) biosensor technique. The first two papers focused on the synthesis and study of biotin selective polymer films prepared using the molecularly imprinted polymer (MIP) technique. LÄS MER

  5. 19. Streptococcal and staphylococcal tissue infections : therapeutic challenges and opportunities

    Författare :Helena Bergsten; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Streptococcus pyogenes and Staphylococcus aureus have been leading causes of human infections throughout history. S. pyogenes is of the top-ten pathogens responsible for most death globally, 0.5 million deaths per year. LÄS MER

  7. 20. Self assembly of surfactants and polyelectrolytes in solution and at interfaces

    Författare :Luis Alejandro Bastardo Zambrano; Per Claesson; Jan Skov Pedersen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surfactant; polyelectrolyte; small–angle neutron scattering; static light scattering; dynamic light scattering; polyelectrolyte–surfactant association; protein; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : This thesis focuses on the study of the interactions between polyelectrolytes and surfactants in aqueous solutions and at interfaces, as well as on the structural changes these molecules undergo due to that interaction. Small–angle neutron scattering, dynamic, and static light scattering were the main techniques used to investigate the interactions in bulk. LÄS MER
