Assessment of toxicity and endocrine-disrupting activity of bisphenol analogues during ozone and UV treatments in zebrafish eleutheroembryos.

In recent decades, increased regulations on the use of bisphenol A (BPA) have prompted a surge in the use of BPA alternatives. Consequently, a widespread occurrence of BPA substitutes in aquatic environments is currently being detected. While some evidence exists about the degradation of these compounds through various water treatment technologies, the evolution of the resulting toxicity and endocrine-disrupting activity during these processes remains scarcely evaluated.

Facilitating microplastic ingestion in aquatic models: A verified protocol for daphnia magna as a trojan horse vector.

Microplastic pollution poses a significant environmental threat due to its persistence, widespread distribution, and inherent toxic potential. Despite the increasing number of publications in this field, a standardized protocol for the laboratory intake of microplastics by has yet to be established. In this study, we introduce a verified protocol designed to facilitate the ingestion of microplastic particles (MPs) by , ranging in size from 5-55 µm.

Efficient removal of toxicity associated to wastewater treatment plant effluents by enhanced Soil Aquifer Treatment.

The regeneration of wastewater has been recognized as an effective strategy to counter water scarcity. Nonetheless, Wastewater Treatment Plant (WWTP) effluents still contain a wide range of contaminants of emerging concern (CECs) even after water depuration. Filtration through Soil Aquifer Treatment (SAT) systems has proven efficient for CECs removal although the attenuation of their associated biological effects still remains poorly understood.

Cerebellar Hemangioblastoma with Leptomeningeal Spread and a Fatal Outcome: A Rare Case Report with and Alterations.

Hemangioblastoma (HB) is a Central Nervous System (CNS) tumor with a generally favorable behavior and prognosis, classified as WHO grade 1. Sporadic HB is not related to any inherited disease, and it usually appears in a single location. Sporadic or VHL-related HBs show variable patterns of growth velocity.

Impact of organic soil amendments in antibiotic levels, antibiotic resistance gene loads, and microbiome composition in corn fields and crops.

The potential spreading of antibiotic resistance genes (ARG) into agricultural fields and crops represent a fundamental limitation on the use of organic fertilization in food production systems. We present here a study of the effect of spreading four types of organic soil amendments (raw pig slurry, liquid and solid fractions, and a digested derivative) on demonstrative plots in two consecutive productive cycles of corn harvest (Zea mays), using a mineral fertilizer as a control, following the application of organic amendments at 32-62 T per ha (150 kg total N/ha) and allowing 5-8 months between fertilization and harvest. A combination of qPCR and high-throughput 16S rDNA sequencing methods showed a small, but significant impact of the fertilizers in both ARG loads and microbiomes in soil samples, particularly after the second harvesting cycle.
