  2. 1. Biotic and abiotic stress in microorganisms and plants: Some Mechanisms of Stress and Programmed Cell Death. Genetic Engineering Approaches Towards Improved Stress Tolerance

    Author : Per-Johan Meijer; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biotic stress; plants; microorganisms; stress tolerance; antifreeze protein; proline; programmed cell death; systemic aquired resistance; Biochemistry; metabolism; Biokemi; Bioteknik; Biotechnology; abiotic stress;

    Abstract : Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. READ MORE

  4. 2. Categorization Work in the Swedish Welfare State : Doctors and social insurance officers on persons with mental ill-health

    Author : Maricel L Knechtel; Michael Allvin; Rafael Lindqvist; Sandra Torres; David Rosenberg; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; institutional categorization; institutional categories; street-level bureaucrats; discretion; sick leave; sick listing; diagnosis; mental illness; psychiatric diagnosis; moral work; deservingness; worthiness; medical sociology; work capability; medical certification; social insurance; vignette studies; discrimination; labeling; stickiness; social mechanisms; matching; screening; signaling; cognitive categorization; working conditions; conflicting demands; client processing; Human Service Organizations; work approach; primary health care; moral stress; Bayes; work capability; rationing; Sociologi; Sociology;

    Abstract : This dissertation contributes to the debate on street-level bureaucracy, which highlights how the decisions made by workers in public bureaucracies effectively become public policy. This debate has paid relatively little attention to the study of how professionals carry out their work by means of institutional categorization, a knowledge gap that this study helps to close.

  5. 3. The γ-aminobutyric acid and proton signaling systems in the zebrafish brain : Characterization and effect of stress

    Author : Arianna Cocco; Svante Winberg; William H. J. Norton; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; g-aminobutyric acid GABA ; GABAA receptors; adult zebrafish; central nervous system; gene expression profiling; extracellular acidification.; Biokemi; Biochemistry;

    Abstract : The central nervous system of vertebrates is continuously processing sensory information relayed from the periphery, integrating it and producing outputs transmitted to efferents. In the brain, neurons employ an array of messenger molecules to filter afferent information and finely regulate synaptic transmission. READ MORE

  6. 4. Control of reactive oxygen species homeostasis in response to environmental stress

    Author : Malgorzata Plaszczyca; Katharina Pawlowski; Jean-Jacques Drevon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stress; antioxidant defense; ascorbate peroxidase; aerenchyma; actinorhiza; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Plants are exposed to various fluctuations in their environmental conditions - light intensity, temperature, water status - and have to adapt in order to survive. Plant acclimatory responses can include the formation of new tissues, e.g., aerenchyma, or the activation of defense systems, e. READ MORE

  7. 5. Peroxiredoxins in Redox Signaling and Aging

    Author : Friederike Roger; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aging; Peroxiredoxin; Redox Signaling; Caloric restriction; light sensing;

    Abstract : Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not clear through what mechanism peroxiredoxins extend lifespan. READ MORE
