  1. 1. Placental Function : An Epidemiological and Magnetic Resonance Study

    Författare :Sara Sohlberg; Anna-Karin Wikstrom; Matts Olovsson; Ajlana Mulic-Lutvica; Johan Wikström; Karel Marsal; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; body height; body mass index; early preeclampsia; late preeclampsia; magnetic resonance imaging; placenta; perfusion; IVIM; risk factors; energy metabolism; magnetic resonance spectroscopy; 31P-MRS; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. LÄS MER

  2. 2. Olfactory Function : The Influence of Demographic, Cognitive, and Genetic Factors

    Författare :Margareta Hedner; Maria Larsson; Lars-Göran Nilsson; Claire Murphy; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfaction; odor identification; odor threshold; odor discrimination; aging; gender; ApoE; BDNF; val66met; association study; population-based; psykologi; Psychology;

    Sammanfattning : Olfactory function is affected by demographic, cognitive, and genetic factors. In the present thesis, three empirical studies investigated individual differences in olfactory ability. Study I explored demographic and cognitive correlates in common olfactory tasks; odor detection, odor discrimination, and odor identification. LÄS MER

  3. 3. Nutrition, exercise and body composition in community-dwelling older adults : Effects on function, wellbeing and mortality

    Författare :Åsa von Berens; Tommy Cederholm; Afsaneh Koochek; Margaretha Nydahl; Peter Nordström; Uppsala universitet; []
    Nyckelord :Older adults; function; nutrition; wellbeing; mortality; exercise; sarcopenic obesity;

    Sammanfattning : Background: The demographic shift in society with more people reaching a high age provides new challenges for both society and the healthcare system.Aim: The overall aim of this thesis was to examine the impact of nutrition, exercise and body composition on function, wellbeing and mortality in community-dwelling older adults.

  4. 4. The semiotic function : studies in children's representations

    Författare :Maare Tamm; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Piaget; Semiotic function; Mental representation Figurative; Operative; Representation media;

    Sammanfattning : The main purpose of this thesis was to explore if there existed one single underlying semiotic function for representation. The problem was examined from both a theoretical and an empirical point of view. LÄS MER

  5. 5. On protein structure, function and modularity from an evolutionary perspective

    Författare :Robert Pilstål; Björn Wallner; Maria Sunnerhagen; Mauno Vihinen; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; structure; biology; intrinsical; disorder; protein; sequence; evolution; mutation; epistasis; function; allostery; dynamics; simulation; prediction; graph; network; bioinformatik; struktur; biologi; strukturbiologi; intrinsiellt; oordnad; protein; sekvens; evolution; mutation; epistasis; funktion; allosteri; dynamik; simulation; prediktion; graf; nätverk;

    Sammanfattning : We are compounded entities, given life by a complex molecular machinery. When studying these molecules we have to make sense of a diverse set of dynamical nanostructures with wast and intricate patterns of interactions. LÄS MER
