  1. 1. Coping with Stress : Regulation of the Caulobacter crescentus cell cycle in response to environmental cues

    Author : Kristina Heinrich; Kristina Jonas; Emanuele Biondi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caulobacter crescentus; bacteria; cell cycle; stress; filamentation; cell morphology; DNA replication; cell division; molekylär biovetenskap; Molecular Bioscience;

    Abstract : All organisms have to respond to environmental changes to maintain cellular and genome integrity. In particular, unicellular organisms like bacteria must be able to analyze their surroundings and rapidly adjust their growth mode and cell cycle program in response to environmental changes, such as changes in nutrient availability, temperature, osmolarity, or pH.

  2. 2. Signalling pathways controlling bacterial adaptation

    Author : Kristina Jonas; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The conversion of environmental signals into cellular responses is a critically important process that occurs in all organisms. The ability to process information depends, in general, on complex signal transduction and regulatory networks that control genes required to cope with certain environmental conditions. READ MORE

  3. 3. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films

    Author : Jonas Högström; Leif Nyholm; Kristina Edström; Patrik Schmutz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; corrosion; electrochemistry; thin film; stainless steel; passive film; chromium carbide; carbon oxidation; surface; depth profile; XPS; SEM; EQCM; sputtering;

    Abstract : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. READ MORE

  4. 4. Regulated Proteolysis: The Secrets of Lon : Cellular Roles and Stress-dependent Regulation of the Lon Protease

    Author : Matthias J. Fink; Kristina Jonas; Axel Mogk; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lon protease; regulated proteolysis; allosteric regulation; Caulobacter crescentus; stress responses; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Proteolysis is crucial in cells to maintain a functional proteome. It is required for removal of damaged and unfolded proteins during protein quality control, and serves as a mechanism to regulate protein levels through regulated proteolysis. READ MORE

  5. 5. Governing Development : The Millennium Development Goals and Gender Policy Change in Sub-Saharan Africa

    Author : Helena Hede Skagerlind; Jonas Tallberg; Kristina Jönsson; Jeffrey Checkel; Mathias Koenig-Archibugi; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Millennium Development Goals; sustainable development; gender equality; human rights; performance indicators; United Nations; Sub-Saharan Africa; Kenya; Ethiopia; economic conditionality; social influence; Political Science; statsvetenskap;

    Abstract : Recent decades have witnessed an upsurge in the use of different forms of global performance assessments as a means to influence the behavior of states. Within the area of international development, the Millennium Development Goals (MDGs) reinforced the practice of development governance through global performance indicators (GPIs) and gained considerable agenda-setting power among the international development community.
