An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Kidney Hematopoietic Stem and Progenitor Cells Contribute to Myeloid Development and Pathology in Lupus Nephritis

open access: yesArthritis &Rheumatology, Accepted Article.
Objectives The hematopoietic system maintains homeostasis by balancing myeloid and lymphoid cell production in the bone marrow (BM). In response to increased hematopoietic demand, extramedullary hematopoiesis (EMH) may occur in non‐lymphoid organs. We investigated the role of EMH and kidney‐resident hematopoietic stem and progenitor cells (HSPCs) in ...

Increased Risk of Intrahepatic Cholestasis of Pregnancy in SLE Women Exposed to Azathioprine

open access: yesArthritis &Rheumatology, Accepted Article.
Objectives To evaluate the risk of intrahepatic cholestasis of pregnancy (ICP) in azathioprine (AZA)‐exposed versus unexposed SLE pregnancies within the multi‐centre prospective Lupus in prEGnAnCY (LEGACY) cohort. Methods LEGACY is conducted at Systemic Lupus International Collaborating Centres in Canada, South Korea, Peru, and Mexico.

Legal and ethical considerations around the use of existing illustrations to generate new illustrations in the anatomical sciences

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 289-300, March 2025.
Abstract It is likely existing anatomical illustrations are often used as the basis for new illustrative works, given not all illustrators have access to human tissues, bodies, or prosections on which to base their illustrations. Potential issues arise with this practice in the realms of copyright infringement and plagiarism when authors are seeking to

Promoting engagement in embryology through gamified student‐developed small group sessions

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Learning embryology is often challenging for students as it requires conceptualizing morphological changes to embryologic structures across time. To further complicate the process, while some structures transition to permanent structures, others disappear or degenerate.

Comparison of examination performance and test anxiety during bell‐paced and self‐paced gross anatomy laboratory examinations

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Pacing during anatomy laboratory examinations may influence both student performance and test anxiety. This study compared bell‐paced (BP) and self‐paced (SP) timing structures to assess their impact on students' test performance, test anxiety, and pacing preferences.
