  2. 11. Impacts of urbanisation on birds : Disentangling the effects of multiple pollutants on avian behaviour and physiology

    Author : Ann-Kathrin Ziegler; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial light at night; ALAN; antioxidants; great tit; light pollution; LPS; multi-stressor; noise pollution; tropospheric ozone; urbanisation; zebra finch;

    Abstract : Anthropogenic pollution is a pervasive feature of urbanisation, reaching into ecosystems worldwide and posing novel challenges to wildlife. Not surprisingly, differences in behaviour, and physiology, have been found between urban and rural populations. READ MORE

  4. 12. Intricate aspects of the thioredoxin system in redox signaling

    Author : Marcus Cebula; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Reversible modifications of redox sensitive protein thiols by reactive oxygen and nitrogen species have emerged as a major posttranslational mechanism that affects the function of the respective proteins and therewith all downstream events. These modifications can be reversed by redox catalysts of which the thioredoxin system forms one of the most prominent. READ MORE

  5. 13. Development of a Sel-tag for multimodality imaging and studies of mammalian thioredoxin reductase 1

    Author : Qing Cheng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Selenocysteine (Sec; U in one-letter code), the 21st amino acid existing in all selenoproteins, has unique biochemical properties due to its selenium atom, including a low pKa and a high reactivity with many electrophilic agents. When a selenoprotein is translated, the insertion of Sec occurs at a UGA codon, normally yielding translational termination. READ MORE

  6. 14. Oxidation of marine oils during in vitro gastrointestinal digestion and its effects on stress in human intestinal Caco-2 cells

    Author : Cecilia Tullberg; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lipid oxidation; human digestive fluids; LC n-3 PUFAs; Caco-2 cells; marine oils; HNE; MDA; in vitro digestion; HHE; gastrointestinal; aldehydes;

    Abstract : Marine oils are attracting public interest due to the preventive effects, e.g., on inflammation, which are linked to the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). However, LC n-3 PUFAs are highly susceptible to oxidation, which could interfere with their positive effects. READ MORE

  7. 15. Altered gene expression in the human airways during oxidative stress

    Author : Tiziana Dandrea; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Nitrogen dioxide; Ozone; Oxidative stress; Gene expression; Redox signalling; GSH; Alveolar macrophages.;

    Abstract : The atmospheric accumulation of pollutant gases, such as N02 and ozone, has been associated with an increased airways hyper-reactivity within the healthy population. Moreover, those with conditions such as asthma and chronic obstructive pulmonary diseases generally experience an exacerbation of their symptoms upon exposure to these noxious gases. READ MORE
