  1. 11. Protein stability and mobility in live cells : Revelation of the intracellular diffusive interaction organization mechanisms

    Författare :Xin Mu; Mikael Oliveberg; Johan Elf; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusive interactions; macromolecular crowding; protein thermodynamic stability; protein mobility; in-cell NMR; Hofmeister series; Biochemistry; biokemi;

    Sammanfattning : Biochemical processes inside living cells take place in a confined and highly crowded environment. As such, macromolecular crowding, one of the most important physicochemical properties of cytoplasm, is an essential element of cell physiology. LÄS MER

  3. 12. Microfluidic blood sample preparation for rapid sepsis diagnostics

    Författare :Jonas Hansson; Hjalmar Brismar; Aman Russom; Fredrik Nikolajeff; KTH; []

    Författare :Young-Keun Kwak; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Staphylococcus aureus is a human pathogen, commonly found in healthy humans as a part of normal flora. alpha-toxin is thought to be largely responsible for the pathogenesis of the bacterium. LÄS MER

  5. 14. The use of protein biomarkers in ecotoxicology : Studies of oxidative and genotoxic stress in the blue mussel (Mytilus edulis)

    Författare :Andreas Prevodnik; Michael Tedengren; Tomas Bollner; Kari Lehtonen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Many environmental pollutants, heavy metals and polyaromatic hydrocarbons (PAHs) among them, are toxic by oxidative stress. Oxidative stress may be defined as a state in an organism when its inherent capacity to handle oxyradicals is surpassed, and it may result in peroxidation of lipids, and damage to proteins and DNA.
