Hematological and Genotoxic Effects of Subchronic Oral Exposure to a Mancozeb‐Based Fungicide in Female Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT The extensive use of pesticides in modern agriculture has raised increasing concerns regarding the potential biological effects of repeated exposure to pesticide residues and commercial formulations. Mancozeb is a widely used ethylene‐bis‐dithiocarbamate fungicide; however, information on its hematological and genotoxic effects following ...

Cellular Toxicity of Short‐ and Long‐Term Exposures to Polystyrene Nanoplastics and Microplastics in Fish Skin Cell Derived From Fathead Minnow (Pimephales promelas)

Journal of Applied Toxicology, EarlyView.
ABSTRACT The ubiquitous presence of microplastics and nanoplastics (MNPs) is raising concerns about their impact on the health of humans and other living organisms. Due to its tiny size, this particle can accumulate and circulate in the body after uptake, resulting in a variety of harmful outcomes on the organism, such as increased oxidative stress and

Etude préliminaire sur l'utilisation de l'Aqui'S® comme anesthésique pour la manipulation et l'échantillonnage de truites arc-en-ciel (Oncorhynchus mykiss) et de truites fario (Salmo trutta)

Knowledge and Management of Aquatic Ecosystems, 1998
La cinétique d'anesthésie de truites arc-en-ciel (Oncorhynchus mykiss) avec de l'Aqui'S® a été suivie sur des animaux de différents poids (9, 25 et 200 g). La vitesse d'anesthésie augmente avec la dose d'Aqui'S® utilisée.

Genome-Wide Association Analysis With a 50K Transcribed Gene SNP-Chip Identifies QTL Affecting Muscle Yield in Rainbow Trout

Frontiers in Genetics, 2018
Detection of coding/functional SNPs that change the biological function of a gene may lead to identification of putative causative alleles within QTL regions and discovery of genetic markers with large effects on phenotypes.

Plasma Proteome Responses in Salmonid Fish Following Immunization

Frontiers in Immunology, 2020
Vaccination plays a critical role in the protection of humans and other animals from infectious diseases. However, the same vaccine often confers different protection levels among individuals due to variation in genetics and/or immunological histories ...

Short‐Term 6PPD‐Q Exposure alters Tight‐Junction‐Related Gene Expression Without Acute Lethality in Japanese Medaka Oryzias latipes

Journal of Applied Toxicology, EarlyView.
ABSTRACT 6PPD‐quinone (6PPD‐Q), a transformation product of the tire antioxidant 6PPD, causes acute mortality in several salmonid species, but its toxicity varies markedly among fish species. Disruption of vascular‐barrier integrity and inflammatory signaling has been proposed as a key mechanism of 6PPD‐Q toxicity.

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...
