ATP and glutamate coordinate contractions in the freshwater sponge Ephydatia muelleri
Abstract Sponges (phylum Porifera) are an early diverging animal lineage that lacks both conventional nervous and muscular systems, and yet they are able to produce coordinated whole-body contractions in response to disturbances. Little is known about the underlying signaling mechanisms in coordinating such responses.

Accumulation of Thallium in Rainbow Trout (Oncorhynchus mykiss) Following Acute and Subchronic Waterborne Exposure
Abstract The accumulation and tissue distribution of toxicants in aquatic biota can be determinative of their toxic impact to both exposed organisms and their potential human consumers. In the present study, accumulation of the trace metal thallium (Tl) in gill, muscle, plasma, and otoliths of rainbow trout (Oncorhynchus mykiss) following acute (96-h) and subchronic (28-day) waterborne exposures was investigated.
The “Trojan Horse” Effect of Nanoplastics: Potentiation of Polycyclic Aromatic Hydrocarbon Uptake in Rainbow trout and the Mitigating Effects of Natural Organic Matter
The “Trojan Horse” Effect of Nanoplastics: Potentiation of Polycyclic Aromatic Hydrocarbon Uptake in Rainbow trout and the Mitigating Effects of Natural Organic Matter Massive annual production of plastics worldwide, coupled with prolonged environmental degradation and poor recycling policies has resulted in serious concerns regarding the ecological impact of these materials.

Comparison of the Hydraulic Fracturing Water Cycle in China and North America: A Critical Review
There is considerable debate about the sustainability of the hydraulic fracturing (HF) water cycle in North America. Recently, this debate has expanded to China, where HF activities continue to grow. Here, we provide a critical review of the HF water cycle in China, including water withdrawal practices and flowback and produced water (FPW) management and their environmental impacts, with a comprehensive comparison to the U.S. and Canada (North America).

Hydraulic Fracturing Return Fluids from Offshore Hydrocarbon Extraction Present New Risks to Marine Ecosystems
Offshore hydrocarbon extraction is an important energy source, with most offshore hydrocarbon extraction performed on shallow continental shelves. More recently, improved technologies (e.g., deep-water drilling and hydraulic fracturing) along with the depletion of easily accessible hydrocarbons have led to an increase in hydrocarbon exploitation from deep-sea environments (Figure 1).(1) Figure 1 Figure 1.
Polyacrylic acid coated nanoparticles elicit endothelial cell apoptosis and diminish vascular relaxation in ex vivo perfused iliac arteries of the cane toad (Rhinella marina).
Polyacrylic acid coated nanoparticles elicit endothelial cell apoptosis and diminish vascular relaxation in ex vivo perfused iliac arteries of the cane toad (Rhinella marina). Nanoparticles (NP) that penetrate external protective barriers of an animal are most likely transported and distributed to various tissues and organs via the circulatory system.
Potentiation of polycyclic aromatic hydrocarbon uptake in zebrafish embryos by nanoplastics
Potentiation of polycyclic aromatic hydrocarbon uptake in zebrafish embryos by nanoplastics The presence of microplastics in the environment and potential effects on the health of organisms is a subject of great concern. However, with further weathering through UV radiation, mechanical force, and microbiological activity, most of these microplastics will degrade into nano-sized particles with exponentially higher surface areas compared to microplastics.
Activity and post-prandial regulation of digestive enzyme activity along the Pacific hagfish (Eptatretus stoutii) alimentary canal
Loading metrics Open Access Peer-reviewed Research Article Alyssa M. Weinrauch , Christina M. Schaefer, Greg G. Goss Alyssa M. Weinrauch, Christina M. Schaefer, Greg G. Goss Published: April 5, 2019 https://doi.org/10.1371/journal.pone.0215027 Figures Abstract Hagfishes are living representatives of the earliest-diverging vertebrates and are thus useful for the study of early vertebrate physiology.
Proposal for a tiered dietary bioaccumulation testing strategy for engineered nanomaterials using fish
The scientific community has invested effort into standardising methodologies for the regulatory ecotoxicity testing of engineered nanomaterials (ENMs), but the practical requirements for bioaccumulation testing of ENMs have been given less attention. A strategy for a tiered approach to bioaccumulation testing of ENMs using fish is proposed, with recommendations for its implementation by regulatory agencies.
UV induced toxicity of cerium oxide nanoparticles (CeO2 NPs) and the protective properties of natural organic matter (NOM) from the Rio Negro Amazon River - Environmental Science: Nano (RSC Publishing)
Electric power and transportation to remote communities in the Amazon Basin is almost entirely derived from use of diesel engines. To increase the fuel efficiency and decrease CO2 emissions, cerium oxide nanoparticles (CeO2 NPs) are increasingly used as a diesel fuel additive.

Post-prandial physiology and intestinal morphology of the Pacific hagfish (<Emphasis Type="Italic">Eptatretus stoutii</Emphasis>)
Hagfishes are unique to the vertebrate lineage in that they acquire dissolved nutrients across multiple epithelia including the intestine, gill, and skin. This feat has been attributed to their immersive feeding behavior that likely simultaneously provides benefits (nutrient rich) and potentially adverse (hypercapnia, hypoxia, high environmental ammonia) physiological effects.
Drinking and water permeability in the Pacific hagfish, <Emphasis Type="Italic">Eptatretus stoutii</Emphasis>
Hagfish are osmoconformers, maintaining an internal osmolality that matches their seawater habitats. Hagfish would, therefore, appear to have no physiological need to drink, but previous studies are equivocal regarding whether drinking in hagfish occurs. The current study addressed this knowledge gap, by examining drinking and water permeability in the Pacific hagfish, Eptatretus stoutii.
Poly (acrylic acid)-coated titanium dioxide nanoparticle and ultraviolet light co-exposure has minimal effect on developing zebrafish (Danio rerio)
Widespread production of titanium dioxide nanoparticles (TiO NPs) for use in various consumer products has increased the potential for their release into the environment. Most studies examine TiO NP toxicity under laboratory lighting that emits little to no ultraviolet (UV) radiation, yet these nanoscale particles are wide band-gap semiconductors capable of generating reactive oxygen species. The purpose of this study was to examine poly (acrylic acid)-coated TiO NP phototoxicity in vivo.
