Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

open access: yesThe Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Single Pixel Imaging Based on Bicubic Interpolation Walsh Transform Matrix

open access: yesIEEE Access
Single pixel imaging is a new method, but imaging quality and speed are the main factors affecting its practicality. Building upon the attributes of the random measurement and deterministic matrices, a Walsh transformation matrix with bicubic ...

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

Dental Applications of Ion-Substituted Hydroxyapatite: A Review of the Literature

open access: yesDentistry Journal
Hydroxyapatite (HA) forms an essential constituent of human teeth and bone. Its distinctive characteristic features, such as bioactivity and osteoconductivity, make it an ideal candidate to be used as an implant coating in restorative dentistry and ...

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Surface Characteristics and Biofilm Development on Selected Dental Ceramic Materials

open access: yesInternational Journal of Dentistry, 2017
Background. Intraoral adjustment and polishing of dental ceramics often affect their surface characteristics, promoting increased roughness and consequent biofilm growth.

Editorial Commentary: A Call for Clarity—Standardizing Return‐to‐Sport Definitions Is Essential for Interpreting Hip Arthroscopy Outcomes

open access: yesArthroscopy, EarlyView.
Abstract Outcome reporting in sports medicine has become increasingly sophisticated, yet sophistication alone does not ensure clinical usefulness. The value, or utility, of an outcome measure lies in its ability to inform patient expectations, shared decision‐making, and treatment selection.

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...
