  1. 11. Functional roles of protein phase separated assemblies in cellular stress response and proteinopathies

    Författare :Michelle Lindström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phase separation; LLPS; stress granules; Lsm7; FUS; Ccr4;

    Sammanfattning : For a long time, pertinent biological conundrums, such as the organization and compartmentalization of the cytoplasm and nucleoplasm, perplexed the scientific community. The organization of the complex biochemistry in an accurate space and time manner could not be explained without the enclosure of a membrane. LÄS MER

  3. 12. Improving Stress Tolerance in Industrial Saccharomyces cerevisiae Strains for Ethanol Production from Lignocellulosic Biomass

    Författare :Valeria Wallace; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; lignocellulose; ethanol; inhibitors; temperature; stress tolerance;

    Sammanfattning : The present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors.

  4. 13. Effects of manufacturing chain on mechanical performance : Study on heat treatment of powertrain components

    Författare :Johan Fahlkrans; Arne Melander; Bengt Lindberg; Stefan Jonsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat treatment; case hardening; carburising; induction hardening; gas quenching; tempering; straightening; fatigue strength; contact fatigue; fracture mechanics; Industriell ekonomi och organisation; Industrial Economics and Management; Production Engineering; Industriell produktion; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The increasing demands for lightweight designs with high strength call for improved manufacturing processes regarding heat treatment of steel. The manufacturing process has considerable potential to improve the mechanical performance and to obtain more reliable results with less variation. LÄS MER

  5. 14. Retinal pigment epithelial cells, oxidative stress and lipofuscin : relation to age-related macular degeneration

    Författare :Staffan Sundelin; Stefan Seregard; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In developed countries, age-related macular degeneration (AMD) is the most common cause of loss of central vision in people over the age of 65. The retinal pigment epithelium (RPE) appears to be the site of early pathological changes in AMD. LÄS MER

  7. 15. Stress induced virulence of Staphylococcus aureus and Listeria monocytogenes

    Författare :Nikoleta Zeaki; Teknisk mikrobiologi; []
    Nyckelord :;

    Sammanfattning : Control of the dissemination of pathogens in the food production chain is an on-going process with new challenges emerging as pathogenic bacteria evolve and express enhanced virulence characteristics. Staphylococcus aureus and Listeria monocytogenes are two notorious pathogens responsible for staphylococcal food poisoning (SFP) and listeriosis: a foodborne intoxication and an infectious disease respectively.
