Metformin prevents mandibular bone loss in a mouse model of accelerated aging by correcting dysregulated AMPK-mTOR signaling and osteoclast differentiation

Journal of Orthopaedic Translation
Background: Age-related mandibular osteoporosis frequently causes loose teeth, difficulty eating, and disfiguration in elders. Bmi1−/− mice displaying accelerated skeletal aging represent a useful model for testing interventions against premature jaw ...

Wing bone laminarity in Pterosaurs: insights into torsional adaptations for flight evolution [PDF]

Anais da Academia Brasileira de Ciências
Powered flight has evolved separately in three tetrapod clades: pterosaurs, birds (avian dinosaurs), and bats. To meet the challenges of powered flight, tetrapods acquired structural, mechanical, and physiological adaptations.

HISTOLOGICAL FEATURES OF LARGE BONE ALLOGRAFTS [PDF]

The Journal of Bone and Joint Surgery. British volume, 1996
We performed biopsies during reoperation for minor complications in two active young patients 9 and 19 months after massive bone allograft implantation for bone tumour. The grafts were dead and resorption-apposition activity, when present, was predominantly in subperiosteal areas. Inflammatory infiltration was very seldom found.
