  2. 1. The oxidative stress response of Francisella tularensis

    Author : Marie Honn; Anders Sjöstedt; Helena Lindgren; Andres Melendez; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; FupA; MglA; OxyR; ROS; oxidative stress; molekylärbiologi; Molecular Biology;

    Abstract : Francisella tularensis is capable of infecting numerous cell types, including professional phagocytes. Upon phagocytosis, F. tularensis resides within the phagosome before escaping into the cytosol to replicate. Phagocytes constitute a hostile environment rich in ROS, which are employed as a means of killing pathogens. READ MORE

  4. 2. Biomarkers of oxidative stress and their application for assessment of individual radiosensitivity

    Author : Siamak Haghdoost; Mats Harms-Ringdahl; Steffen Loft; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oxidative stress; 8-oxo-dG; 8-oh-dG; Radiosensitivity; Toxicology; Toxikologi;

    Abstract : Radiotherapy is one of the most common therapeutic methods for treatment of many types of cancer. Despite many decades of development and experience there is much to improve, both in efficacy of treatment and to decrease the incidences of adverse healthy tissue reactions. READ MORE

  5. 3. Function and Adaptation of Acidophiles in Natural and Applied Communities

    Author : Stephan Christel; Mark Dopson; Michael Schlömann; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acidophiles; Biomining; Psychrophiles; Adaptation; Acid Sulfate Soil; Redox Control; Ecology; Ekologi;

    Abstract : Acidophiles are organisms that have evolved to grow optimally at high concentrations of protons. Members of this group are found in all three domains of life, although most of them belong to the Archaea and Bacteria. READ MORE

  6. 4. On urbanisation and birds : Insights from a molecular and physiological perspective

    Author : Pablo Salmon; Evolutionär ekologi; []
    Keywords : Air Pollution; Antioxidants; Birds; great tit Parus major; Local adaptation; Nitrogen oxides; Oxidative stress; Parallel evolution; Survival; Telomere dynamics; Telomeres; Urbanisation;

    Abstract : Urbanisation of natural habitats is rapidly intensifying and poses a potential global threat for wildlife. Thus, it is important to explore its impact on wildlife in order to understand the present and future threats and how resilient organisms are to them. READ MORE

  7. 5. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco

    Author : Jenny Lindberg; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Abiotic stress; compatible solutes; osmotic stress; osmoprotectants; trehalose; calmodulin; E. coli; N. tabacum; genetic engineering; Biotechnology; Bioteknik; Biochemistry; Metabolism; Biokemi; metabolism; glycine betaine;

    Abstract : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. READ MORE
