  1. 1. Accidental hypothermia and local cold injury : physiological and epidemiological studies on risk

    Författare :Helge Brändström; Michael Haney; Urban Wiklund; Anders Eriksson; Karl-Axel Ängquist; Ola Winsö; Sigridur Kalman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cold-related injuries; hypothermia; frostbite; cold adaptation; rewarming; autonomic nervous system; heart rate variability;

    Sammanfattning : Background: (Papers I and II) The objectives were to first determine incidence and contributing factors to cold-related injuries in northern Sweden, both those that led to hospitalization and those that led to fatality.  (Papers III and IV) A further aim was to assess post-cooling hand-rewarming responses and effects of training in a cold environment, both on fingertip rewarming and on function of the autonomic nervous system, to evaluate if there was adaptation related to prolonged occupational cold exposure.

  3. 2. Biodegradation of the Recalcitrant Endocrine Disruptor Nonylphenol

    Författare :Ana Soares; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm bioreactors; Miljöteknik; pollution control; Environmental technology; Teknik; Technological sciences; white-rot fungi; nonylphenol ethoxylates; endocrine-disrupting activity; contaminated soil; cold-adapted organisms; kontroll av utsläpp; Biotechnology; Bioteknik; biodegradation;

    Sammanfattning : Currently, over 100 high-volume chemicals have been classified as endocrine disrupters. One of these is nonylphenol, which was used as the model compound in this study. This substance originates mainly from the degradation of non-ionic surfactants (nonylphenol ethoxylates) which are widely used in industrial and domestic applications. LÄS MER

  4. 3. Functional morphology of mammalian rhinariumn skin

    Författare :Inga Tuminaite; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nasolabial; skin; epidermis; cutaneous innervation; canine; vascularization; cold acclimatization;

    Sammanfattning : The naked skin surrounding the nostrils in most mammals is called a rhinarium. Rhinarium skin exhibits several unique characteristics, including an ultrastructure of pits or furrows on surface corneocytes, formed in a unique epidermal differentiation process (Paper I). LÄS MER

  5. 4. Fat-Referenced MRI : Quantitative MRI for Tissue Characterization and Volume Measurement

    Författare :Thobias Romu; Magnus Borga; Olof Dahlqvist Leinhard; Samir Sharma; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; water-fat separation; quantitative MRI;

    Sammanfattning : The amount and distribution of adipose and lean tissues has been shown to be predictive of mortality and morbidity in metabolic disease. Traditionally these risks are assessed by anthropometric measurements based on weight, length, girths or the body mass index (BMI). LÄS MER
