  1. 16. Exploring Devices for Molecular Solar Thermal Energy Storage Systems

    Författare :Zhihang Wang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar energy; photochromic molecule; dihydroazulene vinylheptafulvene photoswitches; energy conversion; norbornadiene quadricyclane photoswitches; energy storage;

    Sammanfattning : The sun is considered to be one of the most abundant and renewable sources of energy. During recent last decades, technologies for solar energy capture and storage have been significantly investigated. An attractive way to store solar light, is to use photochromic molecules that can capture and store solar energy in chemical bonds. LÄS MER

  3. 17. Dietary fatty acids increase the absorption of toxic substances and drugs by modifying different absorption pathways in the intestinal epithelium

    Författare :Bitte Aspenström-Fagerlund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Dietary fatty acids have surface active properties comparable to substances used as absorption enhancers of poorly absorbed drugs. The intestinal epithelium serves as a gatekeeping barrier for the absorption of toxic substances, nutrients and drugs. LÄS MER

  4. 18. Airway antioxidant responses to oxidative air pollution and vitamin supplementation

    Författare :Annelie Behndig; Anders Blomberg; Ian S Mudway; Ragnberth Helleday; Isabelle Romieu; Umeå universitet; []
    Nyckelord :Medicine; air pollution; ozone; diesel exhaust; airway inflammation; antioxidant; vitamin C; dehydroascorbate; vitamin supplementation; Medicin; lungmedicin; Lung Medicine;

    Sammanfattning : Air pollutants, such as ozone (O3) and diesel exhaust particles, elicit oxidative stress in the lung. Antioxidants within the respiratory tract lining fluid (RTLF) protect the underlying tissue from oxidative injury. LÄS MER

  5. 19. Tumor lipid status and the responses to therapy in neuroblastoma : with emphasis on treatment monitoring by proton magnetic resonance spectroscopy

    Författare :Magnus Lindskog; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In this thesis, the aberrant lipid and phospholipid metabolism of neuroblastoma was exploited for tumor monitoring and as target of experimental therapy. Neuroblastoma is the most common and deadly solid tumor of childhood. Since neuroblastoma cells are highly proliferative, aberrantly regulated metabolic pathways would be expected. LÄS MER

  7. 20. Fats in Mind : Effects of Omega-3 Fatty Acids on Cognition and Behaviour in Childhood

    Författare :Ulrika Birberg Thornberg; Thomas Karlsson; Magnus Lindgren; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognition; Omega-3 Fatty Acids; Children; ADHD; Executive Functions; kognition; omega-3 fettsyror; barn; ADHD; exekutiva funktioner; Psychology; Psykologi;

    Sammanfattning : The aim of this thesis was to examine possible effects of omega-3 fatty acids on children’s cognition and behavior. Longitudinal as well as cross-sectional comparisons were made among children with typical development and children with ADHD /at risk developing ADHD. LÄS MER
