Two Cases of Dedifferentiated Chordoma in the Sacrum
Korean Journal of Spine, 2015 Dedifferentiated chordoma (DC) is defined as a chordoma containing sarcoma components. DC is distinguished from conventional chordoma by the rapidity of tumor growth and the potential for distant metastasis. We report two cases of DC, which are developed

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans
The Anatomical Record, EarlyView.Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.
