  1. 11. Native protein mass spectrometry of nuclear receptor-ligand and enzyme-substrate complexes

    Författare :Johan Lengqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mass spectrometry; electrospray; nuclear receptor; retinoid X receptor; fatty acid; membrane protein; glutathione transferase; glutathione;

    Sammanfattning : Nuclear receptors (NRs) are transcription factors that are activated by the binding of low molecular weight ligands. The NR superfamily includes receptors for steroid hormones, anti-inflammatory and lipid-lowering drugs as well as endogenous compounds such as bile acids and fatty acids. LÄS MER

  3. 12. GC-MS based metabolomics – Development of a next generation GC-MS method and its application to nutrition and biomarker research

    Författare :Otto Savolainen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gas chromatography; nutrition; biomarkers; metabolomics; mass spectrometry; type 2 diabetes;

    Sammanfattning : Metabolomics, the measurement of a broad range of small molecules in a sample, is maturing as a field in analytical chemistry and becoming a standard research tool in biological sciences for helping to generate a wider understanding of the complex biological mechanisms behind, for example, development of disease and effects of diet on health. Metabolomics analysis is generally divided into either targeted or untargeted metabolomics. LÄS MER

  4. 13. An Experimental and Theoretical Study of the Mass Transport in Lithium-Ion Battery Electrolytes

    Författare :Andreas Nyman; Göran Lindbergh; Mårten Behm; Signe Kjelstrup; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium‐ion batteries; Electrolytes; Transport properties; Conductivity; Diffusion coefficients; Transport number; Maxwell-Stefan equation; Simulations; Mathematical analysis; Polarization; Hybrid electric vehicles; Litiumjonbatterier; Aprotiska elektrolyter; Transport egenskaper; Konduktivitet; Diffusion koefficienter; Transporttal; Maxwell-Stefans ekvation; Simuleringar; Matematisk analys; Polarisation; Elhybridfordon; Electrochemistry; Elektrokemi;

    Sammanfattning : Lithium‐ion batteries are particularly suitable as energy storage solutions in high power applications, such as hybrid electric vehicles. It is generally considered that one of the processes that limit the power density for lithium‐ion batteries is the mass transport in the electrolyte. LÄS MER

  5. 14. Mercury immobilization : a requirement for permanent disposal of mercury waste in Sweden

    Författare :Margareta Svensson; Bert Allard; Anders Düker; Björn Öhlander; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mercury; mercury sulphide; cinnabar; stabilization; solidification; encapsulation; monolith leaching; solubility; mercury speciation; diffusion; apparent diffusion coefficient; Chemistry; Kemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : The Swedish Government states that mercury in the Swedish industry and private use shall be collected and waste containing more than 1% of mercury shall be conditioned for permanent storage in proposed groundwater-saturated repository in deep bedrock. The owners of mercury waste in Sweden are responsible for finding ways to the conversion of the mercury waste to insoluble forms. LÄS MER

  7. 15. Osteoarthritis. Epidemiologic and genetic aspects

    Författare :Jonas Franklin; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; body mass index; knee; hip; epidemiology; Osteoarthritis; occupation; hip fracture; inheritance; natural history;

    Sammanfattning : The purpose of this study was to (I) assess the association between body mass index (BMI) and total hip replacement (THR) and total knee replacement (TKR) due to osteoarthritis (OA), (II) assess the association between the mechanical load of work and THR and TKR due to OA, (III) evaluate the natural history of radiographic hip OA with regards to THR and hip fracture, (IV) to determine the prevalence of radiographic OA in patients with hip fracture, and (V) to examine and compare the inheritance patterns of THR for OA and hip fracture. OA was previously regarded as a consequence of the wear and tear the joint is subjected to during one’s lifetime. LÄS MER
