  1. 1. Cold finger

    Författare :Clas Backman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; vascular; microsurgery; replantation; Cold intolerance; Vasospa;

    Sammanfattning : Post Traumatic Cold Intolerance is the most common, and often the most prominent disabilityfrom hand trauma. The discomfort caused by cold is believed to be linked to a dysfunction o f thedigital vasoregulation, but its pathophysiology is poorly understood. Cold induced vasospasm, i.e. LÄS MER

  3. 2. 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

  4. 3. 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.

  5. 4. In the quest for a cold tolerant variety : gene expression profile analysis of cold stressed oat and rice

    Författare :Angelica Lindlöf; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cold tolerance; oat; rice; bioinformatics analysis; Bioinformatics; Bioinformatik; Technology; Teknik; cold tolerance; oat; rice; bioinformatics analysis;

    Sammanfattning : Cold acclimation is a process which increases the freezing tolerance of an organism, after exposure to low, non-freezing temperatures. The acclimation ensures that cold tolerant species can endure harsh winter conditions, by preparing them to sub-zero temperatures. LÄS MER

  7. 5. Impact of cold climate on boreal ecosystem processes : exploring data and model uncertainties

    Författare :Sihong Wu; Per-Erik Jansson; Annikki Mäkelä; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; net ecosystem exchange; sensible and latent heat fluxes; soil temperature; soil moisture; CoupModel; GLUE;

    Sammanfattning : The impact of cold climate on physical and biological processes, especially the role of air and soil temperature in recovering photosynthesis and transpiration in boreal forests, was investigated in a series of studies. A process-based ecosystem model (CoupModel) considering atmospheric, soil and plant components was evaluated and developed using Generalized Likelihood Uncertainty Estimation (GLUE) and detailed measurements from three different sites.
