Competitive Binding of Persistent Organic Pollutants to the Thyroid Hormone Transport Protein Transthyretin in Glaucous Gull (Larus hyperboreus).
Mortensen, Åse-Karen (Master thesis, 2015)The glaucous gull (Larus hyperboreus) is one of the largest avian top predators in the Arctic. High levels of persistent organic pollutants (POPs) and their metabolites have been detected in the glaucous gull, and several ... -
Evidence of avian influenza virus inseabirds breeding on a Norwegian high-Arctic archipelago
Lee, Megan Marie; Jaspers, Veerle L.B.; Gabrielsen, W. Geir; Munro Jenssen, Bjørn; Ciesielski, Tomasz Maciej; Mortensen, Åse-Karen; Lundgren, Silje Strand; Waugh, Courtney A. (Peer reviewed; Journal article, 2020)Wild aquatic birds serve as the natural reservoir for avian influenza virus (AIV), a disease with significant implications for avian and mammalian health. Climate change is predicted to impact the dynamics of AIV, particularly ... -
The fate of poly- and perfluoroalkyl substances in a marine food web influenced by land-based sources in the Norwegian Arctic
Aasim, Ali M; Langberg, Håkon Austad; Hale, Sarah; Kallenborn, Roland; Mortensen, Åse-Karen; Hartz, William F; Ciesielski, Tomasz Maciej; McDonought, Carrie A.; Jenssen, Bjørn Munro; Breedveld, Gijs D. (Peer reviewed; Journal article, 2021)Although poly- and perfluorinated alkyl substances (PFAS) are ubiquitous in the Arctic, their sources and fate in Arctic marine environments remain unclear. Herein, abiotic media (water, snow, and sediment) and biotic media ... -
Homology modeling to screen for potential binding of contaminants to thyroid hormone receptor and transthyretin in glaucous gull (Larus hyperboreus) and herring gull (Larus argentatus)
Mortensen, Åse-Karen; Mæhre, Silje; Kristiansen, kurt; Heimstad, Eldbjørg Sofie; Gabrielsen, Geir W.; Jenssen, Bjørn Munro; Sylte, Ingebrigt (Journal article; Peer reviewed, 2020)Thyroid hormone disrupting chemicals (THDCs) are of major concern in ecotoxicology. With the increased number of emerging chemicals on the market there is a need to screen for potential THDCs in a cost-efficient way, and ... -
In Vitro and in Silico Competitive Binding of Brominated Polyphenyl Ether Contaminants with Human and Gull Thyroid Hormone Transport Proteins
Hill, Katie L.; Mortensen, Åse-Karen; Teclechiel, Daniel; Willmore, William G.; Sylte, Ingebrigt; Jenssen, Bjørn Munro; Letcher, Robert James (Journal article; Peer reviewed, 2017)Tetradecabromo-1,4-diphenoxybenzene (TeDB-DiPhOBz) is a highly brominated additive flame retardant (FR). Debrominated photodegradates of TeDB-DiPhOBz are hydroxylated in vitro in liver microsomal assays based on herring ... -
Rapid determination of thyroid hormones in blood plasma from Glaucous gulls and Baikal seals by HybridSPE®-LC-MS/MS
Vike-Jonas, Kristine; Villa Gonzalez, Susana; Mortensen, Åse-Karen; Ciesielski, Tomasz Maciej; Farkas, Julia; Venkatraman, Vishwesh; Pastukhov, Mikhail V.; Jenssen, Bjørn Munro; Asimakopoulos, Alexandros (Peer reviewed; Journal article, 2021)A rapid hybrid solid phase extraction (HybridSPE®) protocol tailored to liquid chromatography–electrospray ionization tandem mass spectrometry (LC–ESI–MS/MS) analysis, was developed for the determination of four thyroid ...
