  2. 6. 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. 7. Development of robust cyanobacterial strains for biotechnological applications : Stress tolerance and cell-specific expression in heterocyst-forming cyanobacteria

    Author : Xin Li; Karin Stensjö; Yagut Allahverdiyeva-Rinne; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Dps protein; heterocysts; Nostoc; oxidative stress; cell specific promoter; ROS tolerance; synthetic biology tools transcriptional regulation.; Biokemi; Biochemistry;

    Abstract : Synthetic biology tools can be used to exploit potential applications of cyanobacteria, promising photosynthetic hosts for production of fuels and chemicals. Specific genetic tools are needed for the development of robust cyanobacterial strains for bioengineering. READ MORE

  5. 8. Genetic adaptation to soil acidification in four grasses

    Author : Pernilla Göransson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; Deschampsia flexuosa; Deschampsia cespitosa; Elymus caninus; Poa nemoralis; arbuscular mycorrhiza; stress; tolerance; genetic variation; local adaptation; Al; Soil acidification; pH;

    Abstract : Soil acidification has become a source of serious concern in many parts of the world. In southern Sweden, the deposition of acidifying substances, such as nitrogen and sulphur compounds, has decreased the mean pH of forest soils by almost one unit since the 1950s. READ MORE

  6. 9. Cooperation and conflict over the struggle to reproduce in harsh environments : An experimental field study on ostriches

    Abstract : People are used to hearing that evolution is about the survival of the fittest. Theyimagine a world full of bullies that ruthlessly fight their way to the top in the struggle for life, leaving the weak behind. But this doesn’t need be the case. READ MORE

  7. 10. Gendered experiences of work environment : A study of stress and ambiguity among dental students in Sweden

    Author : Ingrid Schéle; Leif Hedman; Anne Hammarström; Eva Bejerot; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dental students; Swedish dental education; work and organisational theories; gender power relations; ambiguity; perceived stress; satisfaction; grounded theory; content analysis; SEM; cluster analysis; tandläkarstudenter; svensk tandläkarutbildning; arbets- och organisations teorier; genus och makt relationer; ambiguitet; upplevd stress; nöjdhet; grundad teori; innehållsanalys; SEM; kluster analys; Applied psychology; Tillämpad psykologi; Psychology; psykologi;

    Abstract : This thesis explores how dental students experience their education. We aim to generate ways to understand which elements relate to the students’ experience based on current theories and models regarding the quality of working life and gender (and) power relations. READ MORE
