Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

open access: yesThe Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

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.

Identification of Stress-Responsive Transcription Factors Interacting with Cysteine Desulfurase through Co-expression Network Analysis under Drought, Heat, and Salinity Conditions in Potato (Solanum tuberosum)

open access: yesActa Biologica Slovenica
Cysteine desulfurases are essential enzymes involved in sulfur metabolism, redox regulation, and hydrogen sulfide (H₂S) signalling, especially under abiotic stress conditions.

Comparative micro‐ornamentation patterns of reptile skin: Phylogeny‐ecology debate and species‐specific variations

open access: yesThe Anatomical Record, EarlyView.
Phylogenetic limitations seem more decisive than life habit in the diversity of reptile skin micro‐ornamentation. The ancestral form possibly had polygonal cells with regular borders, smooth surface and had no ridges. Cell morphology change gradually on a single scale, especially widths at scale base are greater than those at middle.

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)

open access: yesThe Anatomical Record, EarlyView.
Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

open access: yesAnimal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

Cross‐Species Single‐Cell Comparative Analysis Reveals Gluconeogenic Features of Hepatocytes in Ruminants

open access: yesAnimal Research and One Health, EarlyView.
In this study, we used cross‐species comparisons to identify ruminant hepatocyte features. We also identified potential genes and TFs involved in coordinating gluconeogenesis in ruminant hepatocytes. By integrating single‐cell data with population genetic analyses, we further identified candidate genetic variation in glucose metabolism and ...

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Synchronization and Application of a Novel Hyperchaotic System Based on Adaptive Observers

open access: yesApplied Sciences
This paper explores the synchronization and implementation of a novel hyperchaotic system using an adaptive observer. Hyperchaotic systems, known for possessing a greater number of positive Lyapunov exponents compared to chaotic systems, present unique ...
