Compound and Dose-Dependent Effects of Two Neonicotinoid Pesticides on Honey Bee (Apis mellifera) Metabolic Physiology

open access: yesInsects, 2019
Use of neonicotinoid pesticides is now ubiquitous, and consequently non-targeted arthropods are exposed to their residues at sub-lethal doses. Exposure to these neurotoxins may be a major contributor to poor honey bee colony health.

Protocols for treating C. elegans with pharmacological agents, osmoles, and salts for imaging and behavioral assays

open access: yesSTAR Protocols, 2023
Summary: Research rigor can be enhanced by pairing genetic tools with pharmacology and manipulations of solutes or ions. Here, we present a protocol for treating C. elegans with pharmacological agents, osmoles, and salts. We describe steps for agar plate

Advancing chemical safety assessment through an omics-based characterization of the test system-chemical interaction

open access: yesFrontiers in Toxicology, 2023
Assessing chemical safety is essential to evaluate the potential risks of chemical exposure to human health and the environment. Traditional methods relying on animal testing are being replaced by 3R (reduction, refinement, and replacement) principle ...

Health risk in transport workers. Part II. Dietary compounds as modulators of occupational exposure to chemicals

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2019
Professional drivers are exposed to a number of factors that have a negative influence on their health status. These include vibrations, noise, the lack of fresh air in the car cabin, shift work (frequently at night), monotony resulting from permanent repetition of certain actions, static loads due to immobilization in a sitting position, stress ...

Chemical communication in wood frog (Rana sylvatica) tadpoles is influenced by early-life exposure to naphthenic acid fraction compounds

open access: yesAquatic Toxicology, 2023
Environmental pollutants can disrupt chemical communication between aquatic organisms by interfering with the production, transmission, and/or detection of, as well as responses to, chemical cues. Here, we test the hypothesis that early-life exposure to naphthenic acid fraction compounds (NAFCs) from oil sands tailings disrupts antipredator-associated ...

Biodegradation of mycotoxins: Tales from known and unexplored worlds

open access: yesFrontiers in Microbiology, 2016
Exposure to mycotoxins, secondary metabolites produced by fungi, may infer serious risks for animal and human health and lead to economic losses. Several approaches to reduce these mycotoxins have been investigated such as chemical removal, physical ...
