Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Sargassum Lung Syndrome: Air Flow Obstruction and Bronchial Inflammation Are Observed After Prolonged Exposure to Sargassum Gas Emissions in the Eastern Caribbean

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Sargassum inundation of Caribbean and American shorelines is a growing environmental hazard. Hydrogen sulfide (H2S) and ammonia (NH3) produced by decomposing Sargassum could be involved in airway obstruction and bronchial inflammation. The study was undertaken to evaluate the effects of exposure to H2S and NH3 gases emitted during Sargassum ...

Enhancing Hydrophobic Stability of Silicone Rubber Insulators Under High‐Voltage Direct Current Stress Through Optimised Nano‐Fumed Silica Surface Area: A Dynamic Drop Test Study

open access: yesHigh Voltage, EarlyView.
ABSTRACT The long‐term hydrophobic stability of silicone rubber (SiR) insulators is essential for their reliability in high‐voltage direct current (HVDC) applications. This study investigates the effect of nano‐silica fillers with varying specific surface areas (SSA = 120, 200 and 300 m2/g) and different concentrations of alumina trihydrate (ATH ...

Biochemical and structural characterization of a tail‐spike protein with depolymerase activity identified in a marine podovirus

open access: yesActa Crystallographica Section D, EarlyView.
The marine tail‐spike protein Dpo31 degrades the exopolysaccharide of its host and has structural features similar to those of other members of this protein class, despite similarity not being detected at the sequence level.Marine phages are, through the infection of their bacterial hosts, key regulators of microbiome and carbon fluxes in the ocean ...
