Prenatal exposure to ethanol leads a myriad of developmental disorders known as fetal alcohol spectrum disorder, often characterized by growth and mental retardation, central nervous system damage, specific craniofacial dysmorphic features. The mechanisms toxicity are not fully understood, but during development affects the expression several genes involved in cell cycle control, apoptosis, transcriptional regulation. MicroRNAs (miRNAs) implicated some these processes, however, it is yet...

Layered double hydroxides (LDHs) are stimuli-responsive anionic nanoclays. The vast possibilities of using LDHs can lead to their existence in the ecosystem, raising a question potential ecological concern. However, little is known about effect these nanomaterials on freshwater organisms. present study aimed assess ecotoxicological effects Zinc-Aluminium LDH-nitrate (ZnAl LDH-NO3) zebrafish (Danio rerio) early life stages. endpoints measured were mortality, malformations and hatching rate...

An array of anthropogenic pressures is affecting tropical ecosystems, posing major conservation challenges for scientists, stakeholders and populations. Illegal cyanide fishing one the threats to Indo-Pacific coral reefs, targeting a multitude colorful species marine aquarium trade as well large-sized groupers wrasses food fish trade. Ultimately, continued use this destructive practice oceans warm may overload ecosystems result in irreversible ecological damage. Here we show that impact...

Mutations in genes that encode tRNAs, aminoacyl-tRNA syntheases, tRNA modifying enzymes and other interacting partners are associated with neuropathies, cancer, type-II diabetes hearing loss, but how these mutations cause disease is unclear. We have hypothesized levels of decoding error (mistranslation) do not fully impair embryonic development can accelerate cell degeneration through proteome instability saturation the proteostasis network. To test this hypothesis we induced mistranslation...

Abstract The effects of combined exposure to microplastics and contaminants are still not completely understood. To fill this gap, we assessed the polyethylene terephthalate microplastic fibers (100 mg/L; 360 µm average length) on toxicity silver nanoparticles (AgNPs; 32 nm) nitrate (AgNO 3 ; 0.1–10 µg Ag/L) Daphnia magna . Acute immobilization (median effect concentration [EC50]) cellular energy allocation (CEA; ratio between available consumption) were determined in neonates (<24 h old)...

Bioaccumulation of cadmium was assessed in different tissues the benthic fish Solea senegalensis. Juvenile Senegalese soles were simultaneously exposed to cadmium-contaminated diet (Hediste diversicolor) and water during 14 days allowed depurate for another days. Cadmium content measured muscle, gills, liver intestine, with recorded values increasing these this same order. Muscle showed a considerably lower accumulation after uptake. kinetics juvenile revealed that highest uptake flux metal...

Mesoporous silica engineered nanomaterials are of interest to the industry due their drug-carrier ability. Advances in coating technology include using mesoporous nanocontainers (SiNC) loaded with organic molecules as additives protective coatings. The SiNC biocide 4,5-dichloro-2-octyl-4-isothiazolin-3-one (DCOIT), i.e., SiNC-DCOIT, is proposed an additive for antifouling marine paints. As instability ionic-rich media has been reported and related shifting key properties its environmental...

La vía intranasal es reconocida en medicina humana como una muy promisoria para la administración sistémica y cerebral de fármacos. Es indolora, incruenta, económica práctica. Por sus características, útil aplicación fármacos pacientes con alteraciones orales, diarrea o que no cooperen. Además, potencial directa al sistema nervioso central (SNC). Su uso veterinaria raro, salvo tratamientos locales. En especie equina, aun cuando hay estudios completos profundos sobre las características...

Abstract Due to their general cytotoxic effects, anticancer drugs pose a great risk aquatic species, yet they have been among the least studied groups of regarding environmental impact. The present study aimed identify effects antileukemia drug cytarabine, also known as cytosine arabinoside (ara-C), on development and neurobehavior zebrafish larvae. Zebrafish eggs were exposed cytarabine assess survival, embryonic malformations, locomotor activity, DNA damage, biochemical alterations. No...
