  1. 11. Regulatory mechanisms involved in pathoadaptation of extraintestinal pathogenic Escherichia coli

    Författare :Nikola Zlatkov; Bernt Eric Uhlin; Åke Forsberg; Sun Nyunt Wai; Eliora Ron; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ExPEC; PAIs; pathoadaptation; citrate; metabolism; filamentation; toxins; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Sammanfattning : Establishment of commensal bacteria within a new niche of their host usually promotes the transition from commensalism to pathogenicity. Extraintestinal Pathogenic Escherichia coli (ExPEC) represent different pathovars with biphasic lifestyle – they can reside in the gut as commensals or they can escape and cause diseases elsewhere in the human body.

  3. 12. Microfluidics and AI for single-cell microbiology

    Författare :Praneeth Karempudi; Johan Elf; Yoav Shechtman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microfluidics; Artificial intelligence; Deep learning; Single-cell microbiology; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Most of the biological sciences deal with understanding the relationships between phenotypes and the underlying molecular mechanisms of organisms. This thesis is an engineering, computational, and experimental exercise in expanding the scope and scale of phenotype-genotype mapping techniques in single-cell microbiology using microscopy, microfluidics, and image processing.

    Sammanfattning : Within life science, there is currently an intense search for novel techniques that enable efficient and reliable analysis of biomolecular interactions. Such methods have future applications within medical diagnostics and drug development, as well as within proteomic research in general. LÄS MER

  5. 14. New Roads for an Ancient Enzyme : Whole-Cell Studies and New Cofactors for [FeFe] Hydrogenases

    Författare :Marco Lorenzi; Gustav Berggren; Hannah Shafaat; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; [FeFe] hydrogenases; hydrogen; catalysis; photocatalysis; spectroscopy; whole-cell; semi-artificial enzymes; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Sammanfattning : [FeFe] hydrogenases rare Nature’s best H2-processing catalysts, and one of the best candidates to satisfy societal need for cheap and efficient catalyst for H2-evolution. These enzymes owe their remarkable catalytic activities to their organometallic active site, called “H-cluster”. LÄS MER

  7. 15. Human iPSC-based models of theCNS: attaining cellular biofidelitythrough conventional and advancedculture systems

    Författare :Dimitrios Voulgaris; Anna Herland; Susanna Narkhilakhi; KTH; []

    Sammanfattning : Brain development is a highly orchestrated process that entails changes in microenvironmental cues and growth factor gradients, which set the tempo for proper development of the rudimentary structures of the brain and the generation of neurons,astrocytes, and oligodendrocytes. Another intricate feature of the brain is the bloodbrain barrier (BBB). LÄS MER
