  1. 21. 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. 22. Phasing single DNA molecules with barcode linked sequencing

    Författare :David Redin; Afshin Ahmadian; Ulf Gyllensten; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single molecule sequencing; DNA barcoding; whole genome haplotyping; linked-read sequencing; phasing; de novo genome assembly.; Biotechnology; Bioteknologi;

    Sammanfattning : Elucidation of our genetic constituents has in the past decade predominately taken the form of short-read DNA sequencing. Revolutionary technology developments have enabled vast amounts of biological information to be obtained, but from a medical standpoint it has yet to live up to the promise of associating individual genotypes to phenotypic states of wide-spread clinical relevance.

  4. 23. Carbapenem resistance in Pseudomonas aeruginosa

    Författare :Christian Giske; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Carbapenem (imipenem and meropenem) resistance in Pseudomonas aeruginosa is increasing, with global resistance rates approaching 20%. The most common resistance mechanisms are down-regulation of the porin OprD, and increased activity of multi-drug efflux pumps, primarily MexAB-OprM. LÄS MER

  5. 24. Hodgkin Lymphoma : Studies of Advanced Stages, Relapses and the Relation to Non-Hodgkin Lymphomas

    Författare :Rose-Marie Amini; Volker Diehl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Hodgkin lymphoma; advanced stages; relapse; p53; EBV; Rb; cell line; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Sammanfattning : The relationship between Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) is not entirely elucidated and a clonal relation may be present more often than previously believed. Mechanisms of tumour progression and resistance to therapy are poorly understood.Between 1974 and 1994 all individuals in Sweden with both HL and NHL were identified. LÄS MER

  7. 25. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

    Författare :Rong Cao; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

    Sammanfattning : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. LÄS MER
