  1. 1. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

    Författare :Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

    Sammanfattning : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. LÄS MER

  3. 2. Streptococci and Platelets - A Study of Host-Pathogen Interaction Dynamics

    Författare :Lisbeth Svensson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; host-pathogen interactions; bacterial entrapment; disaggregation; aggregation; platelet activation; Streptococci;

    Sammanfattning : Invasive infections remains one of the leading causes of death due to infections over the world, and efficient treatment remains elusive. One of the major causes of sepsis and other invasive infections is pathogenic streptococci that cause a wide range of clinical manifestations in humans. LÄS MER

  4. 3. Development of 2-Pyridone-based central fragments : Affecting the aggregation of amyloid proteins

    Författare :Magnus Sellstedt; Fredrik Almqvist; Petri Pihko; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2-pyridone; central fragment alteration; multi-component reactions; directed diversity-oriented synthesis; peptidomimetics; amyloid; protein aggregation; pilicide; curlicide; Biorganic Chemistry; bioorganisk kemi;

    Sammanfattning : There are many applications of small organic compounds, e.g. as drugs or as tools to study biological systems. Once a compound with interesting biological activity has been found, medicinal chemists typically synthesize small libraries of compounds with systematic differences to the initial “hit” compound.

  5. 4. Evolutionary and functional studies of protein H: a surface molecule of Streptococcus pyogenes

    Författare :Inga-Maria Frick; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular transportation; adhesion; aggregation; FNIII domain; albumin-binding; M-like protein; convergent evolution; protein G; Streptococcus pyogenes; IgG-binding; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Several bacterial species express surface proteins with affinity for the Fc part of human IgG. This thesis describes evolutionary and functional studies of protein H, an IgGFc-binding surface protein of the human pathogen Streptococcus pyogenes. LÄS MER

  7. 5. Surface proteins of Finegoldia magna interacting with the human host

    Författare :Christofer Karlsson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finegoldia magna; Gram-positive anaerobic cocci; surface proteins; protease; LL-37; MIG CXCL9; Fibrinogen; adhesion; gene disruption; bacterial aggregation; basement membranes;

    Sammanfattning : Finegoldia magna is a Gram-positive anaerobe and a member of the normal human microflora. This bacterium is also an opportunistic pathogen and isolated from ~10% of all anaerobic infections. Reoccurring taxonomical changes and the anaerobic growth have contributed to the neglect of F. magna. LÄS MER
