Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

Journal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Low‐Dose Chlorothalonil Induces Testicular Injury Through Disruption of Steroidogenic Signaling in Adult Male Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chlorothalonil (CHL) is a widely used organochlorine fungicide frequently detected in environmental and food matrices. Although increasing evidence indicates adverse effects in nontarget species, the mechanisms underlying CHL‐induced male reproductive toxicity remain incompletely understood.

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.

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.

From blue light to clock genes in zebrafish ZEM-2S cells.

PLoS ONE, 2014
Melanopsin has been implicated in the mammalian photoentrainment by blue light. This photopigment, which maximally absorbs light at wavelengths between 470 and 480 nm depending on the species, is found in the retina of all classes of vertebrates so far ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Polyphenol dietary supplementation prevents inflammation‐induced muscle atrophy in a zebrafish (Danio rerio) model

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Diet‐induced inflammation is a major cause of muscle degeneration impacting human and animal health. Owing to their anti‐inflammatory and antioxidant properties, polyphenols have attracted considerable interest as feed additives.
