  1. 16. Regulation of biofilm formation in Salmonella typhimurium and Escherichia coli Nissle 1917

    Författare :Cláudia Monteiro; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Bacteria have the ability to grow in cell communities designated biofilms. This mode of growth is widespread and offers numerous advantages to the bacteria in terms of survival, persistence and propagation. Bacteria have developed different ways of building up a biofilm.

  3. 17. Expression and regulation of antimicrobial peptides in mucosal immunity

    Författare :Andreas Cederlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Antimicrobial polypeptides (AMPs) are effector molecules of the innate immune defense. AMPs are mainly expressed in epithelial cells and immune cells, providing the first line of defense to infection as direct antimicrobials. In addition, many AMPs display immunomodulatory functions in both the adaptive and innate immune system. LÄS MER

  4. 18. The efficacy of bacterial viruses against multi-resistant Escherichia coli: from isolation to pharmacology

    Författare :Mohammadali Khan Mirzaei; Anders Nilsson; Rob Lavigne; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phage therapy; Multiresistant E. coli; Pharmacodynamics; Pharmacokinetics; Bacterial viruses; Genomic; proteomic; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The increase of multi-resistant bacteria highlights that the golden era of antibiotics is ending and that alternative treatmentsare urgently needed. Phages have been historically used to treat bacterial infections prior to the discovery of antibiotics and have gained renewed interest in the past decade. LÄS MER

  5. 19. Growth and integrity of the small intestine in malnutrition and trauma

    Författare :Michael Wirén; Linköpings universitet; []
    Nyckelord :Glutamine; growth factors; intestinal mucosa; malnutrition; permeability; surgery; MEDICINE; MEDICIN;

    Sammanfattning : The small intestine is an active metabolic organ constituting a functional and immunologic barrier to toxins and microbes in the intestinal lumen. Injuries are repaired by rapid cell replication, which depends on nutritional and humoral growth factors. Glutamine has been suggested to be the most important nutrient for the enterocytes. LÄS MER

  7. 20. Experimental Studies of Ursolic Acid and Alkaline Sphingomyelinase in Colon Cancer and Colitis

    Författare :David Andersson; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Sphingomyelin (SM) is a sphingolipid present in all eukaryotic cell membranes. Hydrolysis of SM by sphingomyelinase (SMase) generates ceramide, which has effects on cell-cycle regulation and apoptosis. LÄS MER
