  1. 6. 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. 7. Genetic engineering of Yarrowia lipolytica for the sustainable production of food oils

    Författare :Oliver Konzock; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triacyclglycerols; RNA-seq; tolerance; cocoa butter; hydrolysate; yeast; desaturase; filamentation;

    Sammanfattning : The human population and its demand for food oils is constantly growing. However, increasing food oil production currently requires the deforestation of mostly tropical rainforests to allow the plantation of oil crops. LÄS MER

  4. 8. The Role of Proline Catabolism in Candida albicans Pathogenesis

    Författare :Fitz Gerald S. Silao; Per O. Ljungdahl; Joachim Morschhäuser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Candida albicans; proline metabolism; ATP; P5C; virulence; macrophage; hyphae; filamentation; Ras1 cAMP PKA; mitochondria; Proline dehydrogenase; P5C dehydrogenase; reactive oxygen species; Proline-P5C cycle; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Candida albicans is an opportunistic fungal pathogen that has evolved in close association with human hosts. Pathogenicity is linked to an array of virulence characteristics expressed in response to environmental cues and that reflect the requirement to take up and metabolize nutrients available in the host.

  5. 9. Ultrahigh-Voltage Silicon Carbide Device Performance, Requirements, and Limitations in High-Power Applications

    Författare :Daniel Johannesson; Hans-Peter Nee; Staffan Norrga; Muhammad Nawaz; Alberto Castellazzi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 4H-SiC; Current Filamentation; Device Characterization; Dynamic Avalanche; JTE Structure; Junction Termination Extension Design; SiC BJT; SiC GTO Thyristor; SiC IGBT; SiC MOSFET; SiC PiN Diode; Silicon Carbide; TCAD Simulation; Wide bandgap device; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The increased awareness of the on-going climate change accelerates the electric energy system transformation from fossil-fueled power sources towards systems with larger portions of renewable energy sources. Moreover, the grid infrastructure requires reinforcements to cope with increasing electrical energy demand. LÄS MER

  7. 10. Microphysical Conditioning of Gamma-Ray Burst Shocks

    Författare :Jacob Trier Frederiksen; Claes Fransson; Åke Nordlund; Mikhail V. Medvedev; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic fields; particle acceleration; plasma instabilities; gamma-ray bursts; collisionless shocks; relativistic outflows; Astronomy and astrophysics; Astronomi och astrofysik; Astronomy; astronomi;

    Sammanfattning : Gamma-Ray Bursts (GRBs) are believed to be connected with either collapse of massive stars or – in some cases – coalescing neutron stars, both of which cause extreme relativistic explosions observable from the entire Universe. GRBs produce rapid flashes of high energy radiation, extending up to 2MeV in photon energies: as much energy per photon as the rest mass of 4 electrons. LÄS MER
