  1. 6. ADHD and stress : Diurnal cortisol levels, early psychosocial adversity and perceived stress

    Författare :Johan Isaksson; Frank Lindblad; Kent W Nilsson; Per Gustafsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; HPA-axis; cortisol; hypocortisolism; diurnal rhythm; trauma; adversity; medication; perceived stress; gender differences; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Sammanfattning : The Hypothalamus-Pituitary-Adrenal axis (HPA-axis) with its end product cortisol mediates the physiological response to stress thereby promoting mobilization of energy. The cortisol levels follow a diurnal rhythm with a distinct awakening response. LÄS MER

  3. 7. The Stress Hypothesis : Implications for the induction of diabetes-related autoimmunity in children?

    Författare :Anneli Sepa; Ann Frodi; Johnny Ludvigsson; Gunilla Bohlin; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Psychological stress; parenting stress; attachment security; serious life events; children; attitudes; Type I diabetes; beta-cell autoantibodies; prediction; etiology; Medicine; Medicin;

    Sammanfattning : Background: Second to Finland, Sweden has the world’s highest incidence of type 1 diabetes. Experiences of serious life events have retrospectively been shown to constitute a risk factor for the development of this disease, probably via the biological stress response. LÄS MER

  4. 8. Physiological Stress Reactivity in Late Pregnancy

    Författare :Charlotte Hellgren; Inger Sundström-Poromaa; Helena Åkerud; Mats Hammar; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acoustic startle response; allopregnanolone; antenatal; anxiety; cold pressor test; cortisol; cortisol awakening response; depression; electrodermal; estradiol; hypothalamic-pituitary-adrenal axis; postpartum; pregnancy; progesterone; skin conductance; stress; sympathetic nervous system; Medical Science; Medicinsk vetenskap;

    Sammanfattning : During pregnancy, the basal activity is increased in both of our major stress response systems: the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. At the same time, the reactivity towards stressors is reduced. These alterations sustain maternal and fetal homeostasis, and are involved in the regulation of gestational length. LÄS MER

  5. 9. RsbX and stress response in Listeria monocytogenes

    Författare :Ana Henriques de Oliveira; Jörgen Johansson; Cormac Gahan; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; SigB; stressosome; RsbX; phosphorylation; growth; competitiveness; motility; energetic cost; homeostasis; stress response; virulence; invasion; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Sammanfattning : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. LÄS MER

  7. 10. Stress response and virulence in Vibrio anguillarum

    Författare :Barbara Weber; Debra L. Milton; James D. Oliver; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vibrio anguillarum; quorum sensing; Type VI secretion; stress response; virulence; skin colonization; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Bacteria use quorum sensing, a cell to cell signaling mechanism mediated by small molecules that are produced by specific signal molecule synthases, to regulate gene expression in response to population density. In Vibrio anguillarum, the quorum-sensing phosphorelay channels information from three hybrid sensor kinases VanN, VanQ, CqsS that sense signal molecules produced by the synthases VanM, VanS and CqsA, onto the phosphotransferase VanU, to regulate activity of the response regulator VanO.
