Combined Effects of Perfluorooctane sulfonic acid (PFOS) and dissolved Carbon dioxide (CO2) on acute steroidogenic responses in the brain of Atlantic cod (Gadus morhua)
Langberg, Håkon Austad (Master thesis, 2014)Climate changes are often regarded as a concern for the future, but effects are already seen. Increased levels of atmospheric CO2 have resulted in increased levels of dissolved CO2 and a decreased pH in the ocean surface. ... -
Effects of elevated dissolved carbon dioxide and perfluorooctane sulfonic acid, given singly and in combination, on steroidogenic and biotransformation pathways of atlantic cod
Preus-Olsen, Gunnhild; Olufsen, Marianne Opsahl; Pedersen, Sindre Andre; Letcher, RJ; Arukwe, Augustine (Journal article; Peer reviewed, 2014)In the aquatic environments, the predicted changes in water temperature, pO2 and pCO2 could result in hypercapnic and hypoxic conditions for aquatic animals. These conditions are thought to affect several basic cellular ... -
Endocrine, biotransformation, and oxidative stress responses in salmon hepatocytes exposed to chemically induced hypoxia and perfluorooctane sulfonamide (PFOSA), given singly or in combination
Olufsen, Marianne Opsahl; Arukwe, Augustine (Journal article; Peer reviewed, 2015)The effects of hypoxia and perfluorooctane sulfonamide (PFOSA), given singly and also in combination on endocrine, biotransformation, and oxidative stress responses were investigated in primary culture of salmon hepatocytes. ... -
Modulation of membrane lipid composition and homeostasis in salmon hepatocytes exposed to hypoxia and perfluorooctane sulfonamide, given singly or in combination
Olufsen, Marianne Opsahl; Cangialosi, Maria Vittoria; Arukwe, Augustine (Journal article; Peer reviewed, 2014)The relative importance of environmental hypoxia due to global climate change on organismal ability to adapt to chemical insult and/or mechanisms of these responses is not well understood. Therefore, we have studied the ... -
Multiple Environmental Stressors: Biological Interactions Between Parameters of Climate Change and Perfluorinated Alkyl Substances in Fish
Olufsen, Marianne Opsahl (Doctoral thesis at NTNU;2016:100, Doctoral thesis, 2016)Aquatic organisms continuously acclimatize to fluctuations in environment parameters and contaminant insult. The aim of this thesis was to investigate effects of combined exposure to quantifiable measures of climate ...
