An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)

The Anatomical Record, EarlyView.
Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

The Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Rsk2 inhibition induces an aneuploid post-mitotic arrest of cell cycle progression in osteosarcoma cells

Cell Death Discovery
Osteosarcoma is the most common primary bone tumor, which is associated with a high mortality rate. The c-Fos transgenic mouse model has been described to spontaneously develop osteosarcoma, and the ribosomal S6 kinase 2 (Rsk2) was found to be essential ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Impact of Relative Energy Deficiency in Sport (REDs) on Bone Health in Elite Athletes: A Retrospective Analysis

Journal of Cachexia, Sarcopenia and Muscle
Background Relative energy deficiency in sport (REDs) is associated with impaired performance and compromised bone health in elite athletes. While reduced bone mineral density (BMD) and increased risk for bone stress injuries are well documented, the ...
