2023 journal article

Developmental organophosphate flame retardant exposure disrupts adult hippocampal neurogenesis in Wistar rats

NEUROTOXICOLOGY, 99, 104–114.

By: A. Newell n & H. Patisaul n 

author keywords: Neurodevelopment; OPFR; OPE; Flame retardants; Neurotoxicity; Neurotoxicology; Postnatal; Reproductive and developmental toxicology; Hippocampus; Dentate gyrus; Adult hippocampal neurogenesis
TL;DR: Results indicate that developmental OPFR exposure has significant, sex specific impacts on multiple markers of AHN in the dentate gyrus of rats, and further elucidate the developmental neurotoxic properties of OPFRs and highlight the importance of including sex as a biological variable in neurotoxicology research.

Machine learning reveals common transcriptomic signatures across rat brain and placenta following developmental organophosphate ester exposure

Newell, A. J., Jima, D., Reading, B., & Patisaul, H. B. (2023, July 3). TOXICOLOGICAL SCIENCES, Vol. 7.

By: A. Newell n, D. Jima n, B. Reading n  & H. Patisaul n 

author keywords: artificial intelligence; toxicogenomics; neurodevelopment; OPFR; OPE; flame retardants; neurotoxicology; hippocampus; cortex; placenta
TL;DR: It is shown how machine learning can complement more traditional analytical approaches to identify vulnerable "signature" pathways disrupted by chemical exposures and biomarkers of exposure. (via Semantic Scholar)

Maternal organophosphate flame retardant exposure alters the developing mesencephalic dopamine system in fetal rat

TOXICOLOGICAL SCIENCES, 191(2), 357–373.

By: A. Newell n, V. Kapps n, Y. Cai n, M. Rai, G. St Armour n, B. Horman n, K. Rock n, S. Witchey n, A. Greenbaum n, H. Patisaul n 

author keywords: neurodevelopment; monoamine; OPFR; OPE; flame retardants; neurotransmitters; neurotoxicity; neurotoxicology; prenatal; reproductive and developmental toxicology; mesocortical dopamine system; tissue clearing light sheet microscopy.
TL;DR: Results indicate maternal exposure to OPFRs alters the development trajectory of the embryonic dopaminergic system and adds to growing evidence of OPFR developmental neurotoxicity. (via Semantic Scholar)

2019 journal article

The effects of dislocations on crystallographic twins and domain wall motion in magnetite at the Verwey transition

EARTH PLANETS AND SPACE, 71.

By: A. Lindquist*, J. Feinberg *, R. Harrison*, J. Loudon * & A. Newell n

author keywords: Verwey transition; Magnetite; Dislocations; Domain wall; Transmission electron microscopy; TEM; Low-temperature demagnetization; Oxidation; Phase transition
TL;DR: Dislocations, and their associated stress fields, impede the development of monoclinic magnetite twin structures during the phase transition and increase the remanence of a magnetite sample after cooling and warming through the Verwey transition. (via Semantic Scholar)
