Effect of short-term exposure to the strobilurin fungicide dimoxystrobin: Morphofunctional, behavioural and mitochondrial alterations in Danio rerio embryos and larvae
Ahmed, Abdalmoiz I.M.; Macirella, Rachele; Talarico, Federica; Muoio, Mariarosaria F.; Mezzasalma, Marcello; Tronci, Valentina; Lal, Pradeep; Gharbi, Naouel; Brunelli, Elvira (Peer reviewed; Journal article, 2024)Strobilurins, among the most used fungicides worldwide, are considered non-toxic to mammals and birds, but there is growing evidence that these compounds are highly toxic to aquatic species. Dimoxystrobin has been included ... -
Effects of chronic exposure to the water-soluble fraction of crude oil and in situ burn residue of oil on egg-bearing Northern shrimp (Pandalus borealis)
Keitel-Gröner, Frederike; Bamber, Shaw Duncan; Bechmann, Renée Katrin; Lyng, Emily; Gomiero, Alessio; Tronci, Valentina; Gharbi, Naouel; Engen, Frode; Taban, Ingrid Christina; Baussant, Thierry (Journal article; Peer reviewed, 2021)Oil spill clean-up measures using in situ burning can potentially result in seafloor contamination affecting benthic organisms. To mimic realistic exposure and measure effects, ovigerous Northern shrimp were continuously ... -
Exposure to cold temperatures differentially modulates neural plasticity and stress responses in post-smolt Atlantic salmon (Salmo salar)
Tang, Patrik Anthony; Stefansson, Sigurd Olav; Nilsen, Tom Ole; Gharbi, Naouel; Lai, Floriana; Tronci, Valentina; Vigo, Pablo Balseiro; Marnix, M.; Ebbesson, Lars O.E. (Peer reviewed; Journal article, 2022)The transfer success of farmed post-smolt Atlantic salmon (Salmo salar) to sea-cages rely on neural adaptions to promote stress resilience. As low temperatures impact physiology, this suggests that off-season transfer to ... -
Expression and localization of the aryl hydrocarbon receptors and cytochrome P450 1A during early development of Atlantic cod (Gadus morhua)
Aranguren Abadía, Libe; Donald, Carey; Eilertsen, Mariann; Gharbi, Naouel; Tronci, Valentina; Sørhus, Elin; Mayer, Philipp; Nilsen, Tom Ole; Meier, Sonnich; Goksøyr, Anders; Karlsen, Odd Andre (Peer reviewed; Journal article, 2020)The aryl hydrocarbon receptor (Ahr) is a ligand-activated transcription factor that mediates the toxicity of dioxins and dioxin-like compounds (DLCs) in vertebrates. Two clades of the Ahr family exist in teleosts (Ahr1 and ... -
Increased Thermal Challenges Differentially Modulate Neural Plasticity and Stress Responses in Post-Smolt Atlantic Salmon (Salmo salar)
Tang, Patrik Anthony; Gharbi, Naouel; Nilsen, Tom Ole; Gorissen, M.; Stefansson, Sigurd Olav; Ebbesson, Lars O.E. (Journal article; Peer reviewed, 2022)The successful transfer of farmed post-smolt Atlantic salmon (Salmo salar) depends on proper stress responses and cognitive functions during the early seawater (SW) phase. However, with increasing summer oceanic temperatures, ... -
New wine in old bottles: Modification of the Na+/K+-ATPase enzyme activity assay and its application in salmonid aquaculture
Takvam, Marius; Sundell, Kristina; Sundh, Henrik; Gharbi, Naouel; Kryvi, Harald; Nilsen, Tom Ole (Peer reviewed; Journal article, 2023)The Na+, K+ ATPase (NKA) enzyme is important to generate the transmembrane ion gradient in the gills, intestine, and kidneys, hence, is vital for secondary transport of fluids and different solutes in teleosts. Gill NKA ... -
PigghåFRI – Hvordan unngå problemer med pigghå?
Lal, Pradeep; Oosterkamp, Antonie; Brynildsrud, Mette Espedal; Chen, I-Hao; Gharbi, Naouel; Hauss, Helena; Lennox, Robert; Dahlmo, Lotte Svengård; Tressoler, Alan Le; Hansen, Christian Andreas; Nilsen, Marius; Takvam, Marius; Gilannejad, Neda; Tronci, Valentina; Sharp, Mary-Scarlett; Menanteau-Ledouble, Simon; Tang, Patrik Anthony (Research report, 2024)This study has mapped the impact of interaction of spiny dogfish (Squalus acanthias) with aquaculture installations in Norway and studied the behavior of spiny dogfish, in laboratory and field studies, in response to sensory ... -
Reduced α-galactosidase A activity in zebrafish (Danio rerio) mirrors distinct features of Fabry nephropathy phenotype
Elsaid, Hassan Osman Alhassan; Furriol, Jessica; Blomqvist, Maria; Diswall, Mette; Leh, Sabine; Gharbi, Naouel; Anonsen, Jan Haug; Babickova, Janka; Tøndel, Camilla; Svarstad, Einar; Marti, Hans Peter; Krause, Maximilian (Peer reviewed; Journal article, 2022)Fabry disease (FD) is a rare genetic lysosomal storage disorder, resulting from partial or complete lack of alpha-galactosidase A (α-GAL) enzyme, leading to systemic accumulation of substrate glycosphingolipids with a broad ... -

(Peer reviewed; Journal article, 2021)The eye is continuously under oxidative stress due to high metabolic activity and reactive oxygen species generated by daily light exposure. The redox-sensitive protein DJ-1 has proven to be essential in order to protect ... -
Sulfate homeostasis in Atlantic salmon is associated with differential regulation of salmonid-specific paralogs in gill and kidney
Takvam, Marius; Denker, Elsa; Gharbi, Naouel; Kryvi, Harald; Nilsen, Tom Ole (Peer reviewed; Journal article, 2021)Sulfate (urn:x-wiley:2051817X:media:phy215059:phy215059-math-0001) regulation is challenging for euryhaline species as they deal with large fluctuations of urn:x-wiley:2051817X:media:phy215059:phy215059-math-0002 during ... -
