  1. 21. Dietary effects on gene regulation and function in human adipose tissue in obesity

    Författare :Elisabet Nordström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Obesity is an excess of body fat that develops from both genetic and environmental factors, leading to a disturbed balance between energy intake and energy expenditure. It is closely associated with insulin resistance, type 2 diabetes, hyperlipidemia and atherosclerosis. Its increasing prevalence has reached epidemic proportions worldwide. LÄS MER

  3. 22. On the Function of Ceria Supported Rhodium Catalysts for Methanation of Carbon Dioxide

    Författare :Felix Hemmingsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HE-XRD; Catalytic methanation; AP-XPS; In situ spectroscopy; DRIFTS; Sabatier reaction; CO2 reduction; Hydrogenation;

    Sammanfattning : Technologies for energy harvesting of sustainable sources such as solar and wind lack an inherent energy buffer. As such, storing excess energy in chemical bonds, for example that of hydrogen (H2), is a desirable complementary concept. LÄS MER

  4. 23. The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans

    Författare :Daniele A. Cardinale; Filip J Larsen; David Bishop; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondria; OXPHOS; p50mito; mitochondrial oxygen affinity; oxygen extraction; sex difference; hyperoxia; training; muscle metabolism; performance; HIIT; Medicin Teknik; Medicine Technology;

    Sammanfattning : The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions.

  5. 24. Fundamental Investigations of Adsorption in SFC

    Författare :Emelie Glenne; Torgny Fornstedt; Jörgen Samuelsson; Caroline West; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supercritical fluid chromatography; SFC; Adsorption isotherm; Excess adsorption isotherm; Solvent adsorption; Peak distortion; Solute retention; Overloaded peaks; Kemi; Chemistry;

    Sammanfattning : In supercritical fluid chromatography (SFC), the eluent is composed by carbon dioxide, often with additional components, in a condition between gas and liquid. This thesis aims to reach a deeper understanding of SFC by revealing the function of the additional eluent components through systematic adsorption studies. LÄS MER

  7. 25. Effects of excess glucocorticoids on neural cell fate : long lasting consequences of adverse prenatal factors

    Författare :Mirko Conti; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The developing nervous system is particularly vulnerable to high level of glucocorticoids (GCs). Excess GCs is often associated with decreased birth weight in relation to gestational age, and to increased risk of psychiatric disorders, like depression, later in life. LÄS MER
