In Vivo Rapid Assessment of Compound Exposure (RACE) for Profiling the Pharmacokinetics of Novel Chemical Probes [PDF]

open access: yesCurrent Protocols in Chemical Biology, 2012
AbstractThe Rapid Assessment of Compound Exposure (RACE) assay is an easy and efficient method for estimating the pharmacokinetic parameter of exposure (AUC: area under the curve) of novel chemical probe compounds in mice. RACE is a truncated and compressed version of a traditional comprehensive in vivo pharmacokinetics study.

Non-targeted screening methodology to characterise human internal chemical exposure: Application to halogenated compounds in human milk

open access: yesTalanta, 2021
Suspect and non-targeted screening approaches are a matter of increasing interest notably with regard to the Exposome contextual framework, but their application to human samples still remains limited at this date. The aim of the present study was to develop a non-targeted workflow from sample preparation to data processing and method assessment to ...

Standardised bioassays reveal that mosquitoes learn to avoid compounds used in chemical vector control after a single sub-lethal exposure [PDF]

open access: yesScientific Reports, 2022
AbstractVector-borne diseases are worldwide public health issues. Despite research focused on vectorial capacity determinants in pathogen transmitting mosquitoes, their behavioural plasticity remains poorly understood. Memory and associative learning have been linked to behavioural changes in several insect species, but their relevance in behavioural ...

Identification of gp96 as a novel target for treatment of autoimmune disease in mice. [PDF]

open access: yesPLoS ONE, 2010
Heat shock proteins have been implicated as endogenous activators for dendritic cells (DCs). Chronic expression of heat shock protein gp96 on cell surfaces induces significant DC activations and systemic lupus erythematosus (SLE)-like phenotypes in mice.

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 ...
