The subtle divide: a new method for identifying chop marks on long bone diaphyses using fracture morphology

open access: yesFrontiers in Environmental Archaeology
IntroductionChop marks provide critical evidence for reconstructing butchery practices, yet their identification criteria are underdeveloped and rely heavily on the presence of sharp force trauma. Sharp force trauma does not occur with every chop, and on

Dynamics of postnatal bone development and epiphyseal synostosis in the caprine autopod

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Bones develop to structurally balance strength and mobility. Bone developmental dynamics are influenced by whether an animal is ambulatory at birth. Precocial species, which are ambulatory at birth, develop advanced skeletal maturity in utero and experience postnatal development under mechanical loading.

Clinical and research applications of synthetic bone substitutes in equine veterinary medicine: A systematic review

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Bone grafting in equine medicine offers a promising contribution to treating orthopaedic developmental diseases and chondral, osteochondral and segmental bone defects. Among grafts, synthetic bone substitutes—alloplastics—show favourable biological properties addressing numerous limitations presented by autografts, xenografts and ...

Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...
