  1. 26. The effects of temperature on avian physiology, behavior and development

    Författare :Andreas Nord; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clutch size; Cyanistes caeruleus; ecological immunology; energy expenditure; fever; Ficedula hypoleuca; heterothermy; hypothermia; incubation; life history; metabolic rate; Parus major; RMR; Taeniopygia guttata; temperature; winter;

    Sammanfattning : Temperature is a property of profound matter in all aspects of animal life, affecting both individual energy budgets and the environments in which animals reside. Thus, a proper understanding of the effects of temperature variation is instrumental in understanding not only animal form and function, but also the structure and dynamics of wild populations.

  3. 27. Costs and benefits of immune system activation on physiology, behavior and offspring phenotype from an immunoecological perspective

    Författare :Sandra Sköld Chiriac; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunoecology; acute-phase response; sickness behaviors; energy expenditure; fever; hypothermia; life history; maternal effects; terminal investment; costs of immune responses; Taeniopygia guttata; Parus major; Cyanistes caeruleus;

    Sammanfattning : Pathogen challenges and host immune defenses can have substantial impact on life history patterns of animals. Biotic and abiotic factors may affect immunity in wild animals, influencing e.g., population dynamics and sexual selection. LÄS MER

  4. 28. Metabolic effects of interleukin-6

    Författare :Ingrid Wernstedt; Göteborgs universitet; []
    Nyckelord :IL-6; cytokine; obesity; energy expenditure; lipolysis; ASP; sympathetic nervous system; exercise; -174 G C IL-6 polymorphism; fat mass; stress response; cerebrospinal fluid;

    Sammanfattning : The levels of the cytokine interleukin-6 (IL-6) in the circulation are positively correlated with indices of obesity and metabolic disturbances. Paradoxically, plasma IL-6 levels increase markedly during prolonged and strenuous exercise, mainly due to increased production and release from working skeletal muscle. LÄS MER

  5. 29. The Role of Gut Dysfunction and Nutritional Factors in Liver Cirrhosis

    Författare :Evangelos Kalaitzakis; Göteborgs universitet; []
    Nyckelord :liver cirrhosis; malnutrition; gastrointestinal symptoms; health-related quality of life; food intake; energy expenditure; gastric accommodation; gastric barostat; insulin resistance; leptin; ghrelin; intestinal permeability;

    Sammanfattning : Malnutrition is a common finding in patients with liver cirrhosis. Malnutrition has been shown to be associated with increased morbidity and mortality. Its pathogenesis remains unclear but both poor dietary intake and increased energy expenditure have been reported. Spontaneous bacterial peritonitis is an important clinical problem in cirrhotics.

  7. 30. Young vegetarians and omnivores : Dietary habits and other health-related aspects

    Författare :Christel Larsson; Umeå universitet; []
    Nyckelord :Adolescent; Biological markers; Dietary intake; Diet history; Doubly labeled water; Energy expenditure; Food habits; Lifestyle; Nutritional status; Questionnaire; Vegan; Vegetarian; Kostvetenskap; Food and Nutrition;

    Sammanfattning : In the middle of the 1990s many adolescents became vegetarians. There was concern among adults about whether these new young vegetarians got enough energy and nutrients from their dietary intake. LÄS MER
