Gametogenesis-Related Fluctuations in Ovothiol Levels in the Mantle of Mussels from Different Estuaries: Fighting Oxidative Stress for Spawning in Polluted Waters
(MDPI, 2020-02-28)
Reactive oxygen species present a challenge for marine organisms releasing gametes into the water. Thiol-containing molecules protect cells against oxidative stress, and ovothiol (OSH), an antioxidant-reducing mercaptohistidine, ...
Integrated biological response to environmentally-relevant concentration of amitriptyline in Sparus aurata
(Elsevier, 2021-11)
[EN]Amitriptyline (AMI) is a commonly tricyclic antidepressant to treat depression, anxiety, and other conditions. Like many other pharmaceuticals, AMI and its by-products are incompletely removed during wastewater treatment ...
Influence of season-depending ecological variables on biomarker baseline levels in mussels (Mytilus trossulus) from two Baltic Sea subregions
(Science Direct, 2019-06-26)
For reliable mussel monitoring programmes based on biomarkers, regionally relevant reference values and their natural variability need to be known. The Baltic Sea exhibits high inter-regional and seasonal variability in ...
Application of a Biological Multilevel Response Approach in the Copepod Acartia Tonsa for Toxicity Testing of Three Oil Water Accommodated Fractions
(Elsevier, 2021-06-01)
Abstract
Copepods play a critical role in the marine food webs, being a food source for marine organisms. In this study, we investigated the toxic effects of Water Accommodated Fractions (WAFs) from three types of oil: ...
Toxicity to sea urchin embryos of crude and bunker oils weathered under ice alone and mixed with dispersant
(Elsevier, 2022)
[EN] A multi-index approach (larval lenghthening and malformations, developmental disruption, and genotoxicity) was applied using sea-urchin embryos as test-organisms. PAH levels measured in the under-ice weathered aqueous ...
Influence of dispersant application on the toxicity to sea urchin embryos of crude and bunker oils representative of prospective oil spill threats in Arctic and Sub-Arctic seas
(Elsevier, 2021-09-09)
This study deals with the toxicity assessment of crude and bunker oils representative of prospective oil spill threats in Arctic and Sub-Arctic seas (NNA: Naphthenic North-Atlantic crude oil; MGO: Marine Gas Oil; IFO: ...
Antioxidant activities and selenogene transcription in the european sea bass (Dicentrarchus labrax) liver depend, in a non-linear manner, on the Se/Hg molar tatio of the feeds
(Springer Nature ; Humana Press, 2021-07-01)
[EN] Feeding 3.9 and 6.7 mg Hg/kg (Se/Hg molar ratios of 0.8 and 0.4, respectively) for 14 days negatively affected Dicentrarchus
labrax growth and total DNTB- and thioredoxin-reductase (TrxR) activities and the transcription ...
