  1. 26. Effects of dietary fibre on the human metabolism and metabolome

    Författare :Anna Johansson Persson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arabinoxylan; b-glucan; dietary fibre; inflammation; LC-MS; metabolomics; oat; pectin; postprandial response; randomised controlled trial; rye; sugar beet fibre;

    Sammanfattning : It is well-known that dietary fibre can have a positive effect on the development of lifestyle-dependent diseases such as cardiovascular disease and type 2 diabetes. However, the effect may be different for different kinds of fibre and different sub-populations at risk. LÄS MER

  3. 27. Analysis and human levels of persistent perfluorinated chemicals

    Författare :Anna Kärrman; Gunilla Lindström; Bert van Bavel; Ulf Järnberg; Jessika Hagberg; Lennart Hardell; Derek Muir; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; SPE; LC-MS; human exposure; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : An extensive use of perfluorinated chemicals (PFCs) in the last 50 years has resulted in a worldwide spread of these persistent chemicals. Human populations are subjected to a large number of PFCs in ways that are not yet fully explained. LÄS MER

  4. 28. Enrichment of biogenic and anthropogenic organic substances on sea spray aerosols

    Författare :Nikola Radoman; Ian Cousins; Matthew Salter; Jurgita Ovadnevaite; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sea spray; Organic carbon; Dissolved organic matter; Phytoplankton bloom; Cationic surfactants; Perfluorinated alkyl acids; LC-MS; HRMS; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The world’s oceans are the source of one of the most abundant types of natural aerosols, namely sea spray aerosols (SSA). By scattering solar radiation, SSA play a significant role in controlling the Earth’s radiation budget, while they are also involved in the formation of clouds, acting as cloud condensation nuclei (CCN).

  5. 29. Radiobiological effects of the thyroid gland - transcriptomic and proteomic responses to 131l and 211At exposure

    Författare :Nils Rudqvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astatine-211; iodine-131; radionuclide therapy; nuclear medicine; environmental exposure; thyroid; radiation biology; transcriptomics; proteomics; ionizing radiation; toxicity; normal tissue damage; microarray; LC-MS; biomarker;

    Sammanfattning : Radionuclides are widely used in medicine. 131I is one of the most employed radionuclides and is administered to patients either bound to tumor targeting molecules or as halide to target the thyroid or thyroid cancer. LÄS MER

  7. 30. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure

    Författare :Shahid Ullah; Urs Berger; Tomas Alsberg; Michael McLachlan; Jonathan W. Martin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental Science; PFASs; PFAAs; PFOA; PFOS; Precursor; FOSA; PAPs; Method development; LC-MS; SPE; Dietary sample; Drinking water; Human exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. LÄS MER
