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

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Kristina Heinrich; Stockholms universitet.; [2018]
    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. Energy Metabolic Stress Syndrome Impact of Physical Activity of Different Intensity and Duration

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Stefan Branth; Uppsala universitet.; [2006]
    Keywords : Medicine; energy; ATP; metabolism; nutrition; body-composition; physical-activity; stress; insulin-resistance; ion-pumps; intracellular swelling and -shrinkage; taurine; reactive oxygen species; Medicin;

    Abstract : All living cell functions require an ongoing supply of energy derived from carbohydrates, lipids and proteins with their own pathways of breakdown. All of them end up in the oxidation of reduced coenzymes, yielding chemically-bound energy in the form of adenosine triphosphate (ATP). READ MORE

  3. 3. Chronic stress and intestinal barrier function: Implications for infection and inflammation in intensive salmon aquaculture

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Sundh; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Intestinal barrier function; stress; cortisol; Ussing chamber; welfare; health; inflammation; neutrophils; cytokines; chronic stress;

    Abstract : Aquaculture is a fast growing food-producing sector worldwide. This has increased the awareness among the public as well as governments of the need to secure the welfare and health of farmed fish. Atlantic salmon is, in non-Asian countries, one of the most successful aquacultured species. READ MORE

  4. 4. Coordination of two different genomes in response to light and stress

    University dissertation from Umeå : Umeå University

    Author : Louise Norén Lindbäck; Umeå universitet.; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

    Abstract : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. READ MORE

  5. 5. From single-molecule sensing to extracellular vesicles in glioma cells under stress

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Virginia Claudio; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteome; single molecule sensing; nanoplasmonics; surface plasmon resonance; exosomes; glioblastoma; extracellular vesicles; cellular stress; lipid composition;

    Abstract : This thesis describes the work I conducted in two different areas, namely biomolecular sensing and quantitative cell biology. The work in the former area was focused on the optimization of plasmonic metamaterials for sensing applications, and in the latter on the characterization of extracellular vesicles released by glioblastoma cells under stress conditions.
