Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

Student Perceptions of the Implementation of Novel Sonography Phantoms in Radiography Curricula: A Mixed Methods Study

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Anthropomorphic sonography phantoms can assist radiography students with understanding the theoretical principles of sonography. We examined students' perceptions of participating in tutorials which required students to use four sonography phantoms.

Effects of testosterone and high‐dose anabolic steroids on orthodontic‐induced bone remodeling and root resorption: An animal study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study investigates the impact of disruptions in testosterone levels on bone remodeling, root resorption, and periodontal ligament (PDL) during orthodontic tooth movement (OTM) in a pubertal male rat model. Methods Testosterone deficiency was induced through orchiectomy, and the anabolic‐androgenic steroid (AAS, testosterone ...
