  1. 1. Cold Acclimation : Dissecting the plant low temperature signaling pathway using functional genomics

    Författare :Catherine Benedict; Vaughan Hurry; Matsuo Uemura; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cold acclimation; functional genomics; microarray; Populus tremula; Arabidopsis thaliana; gene voting; regulon; enhancer-blocking; Plant physiology; Växtfysiologi;

    Sammanfattning : The physiological process of cold acclimation protects plants native to the temperate regions of the world from the deleterious effects of low and freezing temperatures. This is achieved by a series of transcriptional, regulatory, and metabolic changes that enable continued growth and survival. Within minutes of exposure to temperatures below ca. LÄS MER

  3. 2. 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

  4. 3. Unravelling the complexity of cold acclimation in plants

    Författare :Aakash Chawade; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; cold acclimation; winter; oat; arabidopsis; stress; freezing; genetic networks; metabolomics;

    Sammanfattning : Many plants respond to low non-freezing temperatures by increasing their freezing tolerance in a process known as cold acclimation. Microarray studies have shown that hundreds of genes are differentially expressed during the cold acclimation process in Arabidopsis. LÄS MER

  5. 4. Cold exposure and thermal comfort among patients in prehospital emergency care : innovation research in nursing

    Författare :Jonas Aléx; Britt-Inger Saveman; Stig Karlsson; Ulf Björnstig; Inggard Lereim; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thermal comfort; thermal discomfort; cold exposure; cold stress; hypothermia; patients’ experiences; active warming; prehospital emergency care; finger temperature; back temperature; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : BackgroundPatients’ cold exposure is a neglected problem in prehospital emergency care. Cold stress increases pain and anxiety and contributes to fear and an overall sense of dissatisfaction. When left untreated, cold stress disturbs vital body functions until ultimately reaches hypothermia. LÄS MER

  7. 5. Cold exposure and health : A study on neurological and vascular hand symptoms in northern Sweden

    Författare :Albin Stjernbrandt; Jens Wahlström; Ingrid Liljelind; Tohr Nilsson; Ellen Jørum; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cold climate; Sweden; Hand; Frostbite; Raynaud disease; Peripheral nerve injuries; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Background: Living in a cold climate is associated with several adverse health effects. The main purpose of this thesis was to describe cold exposure characteristics in northern Sweden, and investigate the associations between such exposure and the reporting of neurological and vascular hand symptoms.
