Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Comprehensive Evaluation of Bisphenol A Toxicity Reveals Neurobehavioral, Metabolic, and Reproductive Impairments in Girardia tigrina

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a common industrial chemical used in plastics and consumer products, is increasingly detected in aquatic environments, raising serious concerns about its potential ecological impacts. This study evaluated the sublethal and acute toxic effects of BPA on the freshwater planarian Girardia tigrina, a recognized model for ...

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

Environmental Mycotoxins and Brain Health: Protective Role of Bromelain Against Fumonisin B1 in SH‐SY5Y Cells

Environmental Toxicology, EarlyView.
ABSTRACT Fumonisin B1 (FB1), a mycotoxin commonly found in contaminated food and feed, has been increasingly implicated in neurotoxicity, although its mechanisms remain poorly understood. This study investigates the neurotoxic potential of FB1 in human SH‐SY5Y neuroblastoma cells, both undifferentiated and RA‐differentiated, and evaluates the ...
