Long bone histology and growth patterns in ankylosaurs: implications for life history and evolution.

PLoS ONE, 2013
The ankylosaurs are one of the major dinosaur groups and are characterized by unique body armor. Previous studies on other dinosaur taxa have revealed growth patterns, life history and evolutionary mechanisms based on their long bone histology.

Comprehensive histological evaluation of bone implants [PDF]

Biomatter, 2014
To investigate and assess bone regeneration in sheep in combination with new implant materials classical histological staining methods as well as immunohistochemistry may provide additional information to standard radiographs or computer tomography. Available published data of bone defect regenerations in sheep often present none or sparely labeled ...

The Diagenetic Alterations of Historic Skeletons from the Crown Mines Cemetery, South Africa

Biology, 2023
Human skeletons associated with early gold mining in Johannesburg, South Africa are investigated. An unmarked cemetery was buried beneath a mine dump which resulted in macroscopically stained and poorly preserved bones.

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.

Osteohistology of hyperodapedontine rhynchosaurs from the Upper Triassic of Southern Brazil [PDF]

Acta Palaeontologica Polonica, 2015
The first osteohistological study focused exclusively on rhynchosaurs (non-archosauriform archosauromorphs), based on the hyperodapedontines Teyumbaita sulcognathus and Hyperodapedon sp., from the Upper Triassic of Southern Brazil, indicates a relatively

Sirt1 protects against intervertebral disc degeneration induced by 1,25-dihydroxyvitamin D insufficiency in mice by inhibiting the NF-κB inflammatory pathway

Journal of Orthopaedic Translation, 2023
Background: It has been demonstrated that vitamin D deficiency is associated with an increased risk of patients developing lumbar disc herniation. However, intervertebral disc degeneration caused by active vitamin D deficiency has not been reported. Thus,

Histologic diagnosis of metabolic bone diseases: bone histomorphometry

Reumatismo, 2011
Histomorphometry or quantitative histology is the analysis on histologic sections of bone resorption parameters, formation and structure. It is the only technique that allows a dynamic evaluation of the activity of bone modelling after labelling with tetracycline.

Spatial Organization of Osteoclastic Coupling Factors and Their Receptors at Human Bone Remodeling Sites

Frontiers in Molecular Biosciences, 2022
The strictly regulated bone remodeling process ensures that osteoblastic bone formation is coupled to osteoclastic bone resorption. This coupling is regulated by a panel of coupling factors, including clastokines promoting the recruitment, expansion, and

Tiludronate and clodronate do not affect bone structure or remodeling kinetics over a 60 day randomized trial [PDF]

, 2018
Background Tiludronate and clodronate are FDA-approved bisphosphonate drug therapies for navicular disease in horses. Although clinical studies have determined their ability to reduce lameness associated with skeletal disorders in horses, data regarding
