  2. 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.

  4. 2. Energy Metabolic Stress Syndrome : Impact of Physical Activity of Different Intensity and Duration

    Author : Stefan Branth; Leif Hambraeus; Gunnar Ronquist; Mats Stridsberg; Lennart Kaijser; Uppsala universitet; []
    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

  5. 3. Workload transitions and stress : changes over time

    Author : Erik Prytz; Mark Scerbo; USA VA Norfolk Old Dominion University Department of Psychology; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; human factors; workload transition; stress; workload;

    Abstract : Workload transitions are situations where operators are suddenly confronted with levels of workload substantially different from previously established levels. Workload transitions may affect the operators' state of stress and coping behaviors but previous research has not conclusively demonstrated the nature of those. READ MORE

  6. 4. The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity

    Author : Niklas Gustavsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; oxidative stress; thermostability; temperature stress; stress tolerance; sHsp; protein aggregation; molecular chaperone; Heat stress; methionine sulfoxidation; Biokemi; metabolism; Plant biochemistry; Växtbiokemi;

    Abstract : The chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. READ MORE

  7. 5. Fibromyalgia syndrome in women - a stress disorder? : Neurobiological and hormonal aspects

    Author : Ulla Maria Anderberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Fibromyalgia; stress; sex hormones; premenstrual syndrome; neuropeptides; personality; Neurovetenskap; Neurology; Neurologi; Psychiatry; psykiatri;

    Abstract : The FMS is almost exclusively a female disorder, as 90% of the patients struck by it are women. About 7% of all women in modern society have this disorder. READ MORE
