  1. 11. Cancer Risk Assessment of Glycidol : Evaluation of a Multiplicative Risk Model for Genotoxic Compounds

    Författare :Jenny Aasa; Margareta Törnqvist; Elaine M. Faustman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycidol; 3-monochloropropane-1; 2-diol 3-MCPD ; genotoxicity; mutations; micronuclei; hemoglobin adducts; in vivo dose; multiplicative risk model; cancer risk assessment; human cancer risk; miljökemi; Environmental Chemistry;

    Sammanfattning : Humans are exposed to chemical compounds in everyday life, both from the environment and from endogenous processes. Some compounds constitute a risk for cancer development. One such compound is glycidol, which is genotoxic and an animal carcinogen. It is the model compound of this work, partly due to its presence in food. LÄS MER

  2. 12. Amino acids with relevance to health, climate and the environment : Development of mass spectrometric methods

    Författare :Javier Zurita; Leopold Ilag; Ulrika Nilsson; Margareta Törnqvist; Natalia Tretyakova; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amino acids; LC MS; fixed-charge derivatization; BMAA; chiral separation; pheromones; arctic aerosols; serum albumin adducts; benzo[a]pyrene diol epoxides; high-resolution MS; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Amino acids play vital roles in health, either in their native form or chemically modified. Some studies have linked certain non-proteinogenic amino acids to neurodegenerative diseases, such as in the case of β-methylaminoalanine (BMAA). LÄS MER

  3. 13. Nuclear receptor functions in the central nervous system : clues from knockout mice

    Författare :Sandra Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Estrogen receptor; liver X receptor; 5alpha-androstane-3beta; 17beta-diol; brain development; neuronal degeneration; spinal cord; motor neuron.;

    Sammanfattning : The nuclear receptor (NR) superfamily is the largest known family of transcription factors in eukaryotes. In the 1980 s when the size of the NR family and the scope of the functions of its members were being discovered, tissue distribution studies revealed that the mRNAs of many of these receptors were expressed in the central nervous system.

  4. 14. Factors Influencing the Yield of Mutations Induced by Polycyclic Aromatic Hydrocarbons in Mammalian Cells

    Författare :Anne Lagerqvist; Dag Jenssen; Klaus Erixon; Fredrik Johansson; Hanspeter Naegeli; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi; toxikologisk genetik; Toxicological Genetics;

    Sammanfattning : Environmental contaminants are ubiquitously present in the urban environment, this has the implication that humans are exposed to toxic and carcinogenic chemicals. Polycyclic aromatic hydrocarbons (PAH) are one type of environmental contaminants, which are produced by combustion of organic compounds. LÄS MER

  5. 15. Insights into dynamic covalent chemistry for bioconjugation applications

    Författare :Shujiang Wang; Oommen Varghese; Nicola Tirelli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamic covalent chemistry; reaction mechanism; hydrogel; bioconjugation; catalysis; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : Dynamic covalent chemistry (DCC) is currently exploited in several areas of biomedical applications such as in drug discovery, sensing, molecular separation, catalysis etc. Hydrazone and oxime chemistry have several advantages, such as mild reaction conditions, selectivity, efficiency, and biocompatibility and therefore, have the potential to be for bioconjugation applications.
