The Potentiating Effect of Graphene Oxide on the Arylhydrocarbon Receptor (AhR)–Cytochrome P4501A (Cyp1A) System Activated by Benzo(k)fluoranthene (BkF) in Rainbow Trout Cell Line

Autor: Ana Valdehita, María Luisa Fernández-Cruz, José M. Navas

Publikováno v: Nanomaterials, Vol 13, Iss 18, p 2501 (2023)

The increasing use of graphene oxide (GO) will result in its release into the environment; therefore, it is essential to determine its final fate and possible metabolism by organisms. The objective of this study was to assess the possible role of the

Cytotoxicity against fish and mammalian cell lines and endocrine activity of the mycotoxins beauvericin, deoxynivalenol and ochratoxin-A

Autor: José María Navas, Ana Valdehita, V. García-Herranz, María Luisa Fernández-Cruz

Publikováno v: Food and Chemical Toxicology. 127:288-297

The toxicity of mycotoxins is well recognized in mammals, but their effects on fish have received less attention. Moreover, in the last years several studies have reported that some mycotoxins may act as endocrine disruptors. The aim of this study wa

Acute toxic effects caused by the co-exposure of nanoparticles of ZnO and Cu in rainbow trout

Autor: María Luisa Fernández-Cruz, Isabel Rucandio, Ana Valdehita, José María Navas, David Hernández-Moreno, Estefanía Conde

Publikováno v: The Science of the total environment. 687

The toxic effects produced by the co-exposure to low- and non-toxic concentrations of zinc oxide (ZnONPs) and copper nanoparticles (CuNPs) was assessed in rainbow trout following the OECD Test Guideline 203. Four groups of trouts were exposed for 96

Androgens and androgenic activity in broiler manure assessed by means of chemical analyses and in vitro bioassays

Autor: Maria-Luisa Fernández-Cruz, Eduardo Becerra-Neira, José María Navas, María Isabel González-Gullón, María Mar Delgado, Ana Valdehita, Mari Cruz García-González

Publikováno v: Environmental Toxicology and Chemistry. 36:1746-1754

The use of manure as an agricultural amendment is increasing the release of steroid hormones into the environment. Most research in this field has focused on estrogenic phenomena, with less attention paid to androgenic substances. The present study a

In mammals, numerous reports describe an immunomodulating effect of thyroid-active compounds. In contrast, only few reports have been published on this subject in fish. We previously demonstrated that immune cells of rainbow trout (Oncorhynchus mykis
