Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

The Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Importin-7 promotes tension-induced osteogenesis by regulating RUNX2 nuclear translocation during orthodontic tooth movement

Scientific Reports
Orthodontic tooth movement (OTM) is primarily driven by alveolar bone remodeling, wherein tension-induced osteogenesis plays a central role. Importin7 (IPO7) has been identified as a highly mechanoresponsive nuclear transport receptor (NTR). However, its

The Results of the Treatment of Osteogenesis Imperfecta with Corkscrew Tipped Telescopic Nail

, 2017
Aim: We aimed to evaluate the clinical and radiological results of an intramedullary fixation system used in surgeries for fractures and deformities of osteogenesis imperfecta where we applied a new design corkscrew tipped intramedullary nailing ...

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

The Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Ventriculosubgaleal shunt placement for hydrocephalus in osteogenesis imperfecta with novel compound heterozygous CRTAP variants

Human Genome Variation
Osteogenesis imperfecta is characterized by frequent fractures, bone deformities, and other systemic symptoms. Severe osteogenesis imperfecta may progress to hydrocephalus; however, treatment strategies for this complication remain unclear.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

First reports on the relationship between the eggshell and bone mineralization in Rhinoclemmys punctularia punctularia embryos

The Anatomical Record, EarlyView.
Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...

Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis

Animal Research and One Health, EarlyView.
Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).
