  2. 11. Mechanisms of microbial-host interaction during asymptomatic bacteriuria

    Author : Jenny Grönberg Hernandez; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asymptomatic bacteriuria; Urinary tract infection; Escherichia coli 83972; IRF3; TLR4; Evolution; host response; promoter polymorphisms; transcription; P fimbriae; Type 1 fimbriae;

    Abstract : Urinary tract infections (UTIs) present an interesting and relevant model for studying microbial adaptation. After establishing significant numbers, the bacteria either cause severe disease, or an asymptomatic carrier state resembling the normal flora at other mucosal sites. READ MORE

  4. 12. Experimental studies on the role of the gastrointestinal microflora in postsurgical adhesion formation

    Author : Claes Bothin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adhesions; adhesion formation; germfree; microflora;

    Abstract : Introduction: Adhesions occurring after any kind of surgery is a common phenomenon and cause a great deal of morbidity and mortality, incurring a considerable burden on health care systems. Adhesions are especially prominent after lower abdominal and gynecological procedures (60-90 % of patients after one operation) causing infertility, pain syndromes and bowel obstruction as well as complicating subsequent surgery.

  5. 13. Tuning the long-term properties to control biodegradation by surface modifications of agricultural fibres in biocomposites

    Author : Thorsak Kittikorn; Monica Ek; Ferruccio Doghieri; KTH; []
    Keywords : agricultural fibres; biocomposites; renewable polymers; PP; PLA; PHBV; surface modifications; water uptake; microbial growth; biodegradation;

    Abstract : Sustainable polymeric materials put emphasis on mastering the whole life-cycle of polymeric materials. This includes the choice of raw materials, selection of synthesis and processing, environmental impact during long-term use followed by detailed knowledge about recycling and waste management.

  6. 14. Physico-chemical characterisation of microbial cell surface and bioflotation of sulfide minerals

    Author : Prashant K. Sharma; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Biomineral beneficiation concerns the way in which microorganisms bring about the enrichment of an ore matrix. It involves the selective removal of undesirable mineral constituents from an ore through microbe-mineral interactions in the process such as selective flotation and flocculation. READ MORE

  7. 15. Host-pathogen interactions during Campylobacter and Yersinia infections

    Author : Nayyer Taheri; Anna Fahlgren; Maria Fällman; Sun Nyunt Wai; Elena Vikström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Campylobacter jejuni; Yersinia pseudotuberculosis; OMV; bile; temperature; proteomic;

    Abstract : The innate immune system is known for protecting the host against invading pathogens, for instance enteropathogens infecting the gastrointestinal tract. The production of e.g. antimicrobial peptides, cytokines, and chemokines by innate immune cells and intestinal epithelial cells contribute to bacterial clearance. READ MORE
