Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Characterization of the microstructural properties that are predictive of regain in strength in phosphate-deficient mice [PDF]

open access: yes, 2016
Fracture healing occurs in a discrete set of steps, which recapitulates embryonic endochondral bone formation. Pathophysiologies of the fracture healing that prolong the fracture repair or result in non-union may be associated with either environmental ...

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

The importance of markers of osteolysis and osteogenesis in the pathogenesis of cephalohematoma in newborns

open access: yesActa Biomedica Scientifica
Background. Of particular importance in the repair process for cephalohematomas is the pathological remodeling of the bones of the cranial vault. Local changes in the bones of the skull are accompanied by the processes of osteolysis and osteogenesis and ...

Early Condylectomy: Biological Considerations [PDF]

open access: yes, 2018
Objective: To describe the early treatment of two patients with unilateral condylar hyperplasia (UCH) diagnosis and therapeutic surgical protocol (early condylectomy) supported by the current biological knowledge about the development and repair of ...

Trabecular bone ontogeny of the human talus

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Dnmt3b ablation impairs fracture repair through upregulation of Notch pathway [PDF]

open access: yes, 2020
We previously established that DNA methyltransferase 3b (Dnmt3b) is the sole Dnmt responsive to fracture repair and that Dnmt3b expression is induced in progenitor cells during fracture repair.

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

open access: yesThe Anatomical Record, EarlyView.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

Epibulbar Complex Choristoma Containing Bone: A Case Report and Closer Look at Classifications

open access: yesCase Reports in Ophthalmology
Introduction: Epibulbar choristoma is a benign congenital lesion containing histologically normal-appearing tissue in an abnormal ectopic location. An epibulbar choristoma is classified as either epibulbar dermoid, dermolipoma, or complex choristoma ...
