    Sammanfattning : The relationship between the state and the people is a central theme in political theory. Discussions in this field have often centered on how a people can come to constitute a state. Less attention, however, has been directed toward the state’s role in constituting and recreating its people. LÄS MER

  2. 2. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction

    Författare :Emmanouil Tsakoumis; Monika Schmitz; Tatjana Haitina; Åsa Wallén-Mackenzie; Ana Gómez Peris; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; zebrafish; leptin; appetite; GRN; brain; reproduction; oocyte maturation; ovulation; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Sammanfattning : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. LÄS MER

  3. 3. Allocation of body resources to reproduction in butterflies

    Författare :Fredrik Stjernholm; Bengt Karlsson; Christer Wiklund; Jane K. Hill; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biology; Zoology; Ecology; Butterflies; Reproduction; Life histories; Trade-offs; Resource use; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The life-history of an organism can be studied and understood in terms of acquisition and expenditure of resources. In butterflies, the use of resources for reproduction has been the focus of much research due to the possibility to easily quantify both the input of resources from different sources over the life-cycle as well as the partitioning of these resources to reproduction.

    Sammanfattning : ABSTRACT Optimal breeding of mice is very important in biomedical science today. The understanding why some strains breed better and some worse enable scientists to create better in vivo models for human diseases. LÄS MER

  5. 5. Attityder till barnfrihet : (Icke-)reproduktionens betydelse

    Författare :Ylva Nettelbladt; Ilkka Henrik Mäkinen; Sandra Torres; Helen Peterson; Uppsala universitet; []

    Sammanfattning : This thesis is a study in attitudes towards voluntary childlessness. The specific aim is to investigate attitudes towards voluntary childlessness in a society with pronatalist values: how are they structured and how can the structure be interpreted in the Swedish context? As inspiration and theoretical framework the theory of “the value of children”, that was developed by Lois W. LÄS MER
