Assessing the Acute and Chronic Effects of Palladium on Daphnia magna and the Influence of Natural Organic Matter. [PDF]

open access: yesJ Appl Toxicol
ABSTRACT In recent decades, rising industrial demand for palladium (Pd), driven by its unique properties and affordability compared to other noble metals, has increased its environmental release into aquatic systems. This highlights the need to assess its effects on organisms, given the lack of standardized toxicity studies and regulations for this ...

Metabolic disrupting chemicals in the intestine: the need for biologically relevant models: Zebrafish: what can we learn from this small environment-sensitive fish? [PDF]

open access: yesFEBS Open Bio
In this review, we aimed to study how the intestine may be disrupted by metabolic endocrine disruptors (MDCs) both in its own metabolism and in its relationships with other organs. Zebrafish shares numerous similarities with human gastrointestinal tract, representing an opportunity to study the complex interactions of MDCs at the intestinal level and ...

Mutation of Brain Aromatase Impairs Behavior and Neuroplasticity in Adult Zebrafish. [PDF]

open access: yesJ Neurochem
This study investigates the functional role of brain aromatase, encoded by the cyp19a1b gene, in zebrafish neurodevelopment and adult behavior. Using TALENs technology, we introduced a 10‐nucleotide deletion in exon 2, generating a zebrafish line that expresses a truncated aromatase protein.

The Comet Assay, a Sensitive Biomarker of Water Quality Improvement Following Adoption of Beneficial Agricultural Practices?

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 10, Page 2201-2214, October 2023., 2023
Abstract Numerous actions have been undertaken by farmers to attenuate the impact of agricultural activities on aquatic ecosystems. The identification of biomarkers that respond quickly to water quality improvement could facilitate the assessment of adopted alternative practices and help maintain mobilization among stakeholders.

Combinatorial pathway disruption is a powerful approach to delineate metabolic impacts of endocrine disruptors

open access: yesFEBS Letters, Volume 596, Issue 24, Page 3107-3123, December 2022., 2022
In this review, we describe endocrine disruptor (ED)‐related alterations in tissues involved in metabolic homeostasis, that is, adipose tissue, liver, pancreas, intestine and brain. We also present epigenetic effects of EDs. Finally, we propose an integrative view of multi‐organ alterations that explain how EDs can contribute to the development of ...
