Defining the Biologically Plausible Taxonomic Domain of Applicability of an Adverse Outcome Pathway: A Case Study Linking Nicotinic Acetylcholine Receptor Activation to Colony Death

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 71-87, January 2023., 2023
Abstract For the majority of developed adverse outcome pathways (AOPs), the taxonomic domain of applicability (tDOA) is typically narrowly defined with a single or a handful of species. Defining the tDOA of an AOP is critical for use in regulatory decision‐making, particularly when considering protection of untested species.

Osteohistological characterization of notosuchian osteoderms: Evidence for an overlying thick leathery layer of skin

Journal of Morphology, Volume 284, Issue 1, January 2023., 2023
The perpendicular insertion of Sharpey's fibers in the external cortex suggests the presence of a thick leathery skin layer overlying notosuchian osteoderms. Although intramembranous ossification is the main process involved in the development of crocodyliform osteoderms, we reported a case of metaplastic development.

A proteome‐scale analysis of vertebrate protein amino acid occurrence: Thermoadaptation shows a correlation with protein solvation but less so with dynamics

Proteins: Structure, Function, and Bioinformatics, Volume 91, Issue 1, Page 3-15, January 2023., 2023
Abstract Despite differences in behaviors and living conditions, vertebrate organisms share the great majority of proteins, often with subtle differences in amino acid sequence. Here, we present a simple way to analyze the difference in amino acid occurrence by comparing highly homologous proteins on a subproteome level between several vertebrate model
