: In recent years the global incidence of cancer during pregnancy is rising, occurring in 1 out of every 1000 pregnancies. In this regard, the most used chemotherapy drugs to treat cancer are alkylating agents such as cyclophosphamide (Cp). Despite its great efficacy, has been associated with the production of oxidative stress and DNA damage, leading to embryotoxicity, genotoxicity, and teratogenicity in the developing .

Nanoplastics pose a growing threat to marine ecosystems, particularly affecting the early developmental stages of marine organisms. This study investigates the effects of amino-modified polystyrene nanoparticles (PS-NH, 50 nm) on the embryonic development of , a model ascidian species. Both chorionated and dechorionated embryos were exposed to increasing concentrations of PS-NH so morphological alterations could be assessed with a high-content analysis of the phenotypes and genotoxicity.

Nonylphenol (NP), a non-ionic surfactant and potent endocrine disruptor, is known for its environmental persistence, biotic accumulation potential and toxicity. Nonetheless, mechanisms underlying NP modulation of female fertility with potential impact on embryogenesis in the unexposed offspring remain elusive. This study investigates the effects and toxic mechanisms of maternal exposure to NP at varying concentrations (50 and 100 μg/L) on zebrafish (Danio rerio), specifically focusing on ovarian health, reproductive parameters, and early developmental potential in the F1 generation.

Volatile oils (VOs), synonymously termed essential oils (EOs), are highly hydrophobic liquids obtained from aromatic plants, containing diverse organic compounds for example terpenes and terpenoids. These oils exhibit significant neuroprotective properties, containing antioxidant, anti-inflammatory, anti-apoptotic, glutamate activation, cholinesterase inhibitory action, and anti-protein aggregatory action, making them potential therapeutic agents in managing neurodegenerative diseases (NDs). VOs regulate glutamate activation, enhance synaptic plasticity, and inhibit oxidative stress through the stimulation of antioxidant enzymes.

Fullerenols, a water-soluble polyhydroxy derivative of fullerene, hold promise in medical and materials science due to their unique properties. However, concerns about their potential embryotoxicity remain. Using a pregnancy mouse model and metabolomics analysis, our findings reveal that fullerenols exposure during pregnancy not only significantly reduced mice placental weight and villi thickness, but also altered the classes and concentrations of metabolites in the mouse placenta.
