UNLABELLED FRFP binds to mineral at osteoblastic, osteoclastic, and quiescent surfaces, with accumulation likely modulated by vascular delivery. In vivo visualization and quantification of binding can be accomplished noninvasively in animal models through optical tomographic imaging. INTRODUCTION The development of near-infrared optical markers as reporters of bone metabolism will be useful f...

OBJECTIVES To compare serum markers of bone formation with the urinary excretion of pyridinium crosslinks (PYR) as a possible measure of bone and cartilage degradation which would detect changes in bone metabolism in patients with ankylosing spondylitis (AS) and to relate them to influences of inflammatory disease activity, and to treatment. METHODS In 62 patients with AS, serum osteocalcin, ...

Osteoporosis is characterised by a progressive loss of bone mass and microarchitecture which leads to increased fracture risk. Some of the drugs available to date have shown reductions in vertebral and non-vertebral fracture risk. However, in the ageing population of industrialised countries, still more fractures happen today than are avoided, which highlights the large medical need for new tre...

Osteoporosis may complicate iron overload diseases such as genetic hemochromatosis. However, molecular mechanisms involved in the iron-related osteoporosis remains poorly understood. Recent in vitro studies support a role of osteoblast impairment in iron-related osteoporosis. Our aim was to analyse the impact of excess iron in Hfe-/- mice on osteoblast activity and on bone microarchitecture. We...

background and aims. recent literature shows that accelerated portland cement (apc) is a non-toxic material that may have potential to promote bone healing. the objective of this study was to histologically evaluate periodontal healing focusing on new bone regeneration following implantation of apc into intra-bony defects in dogs. materials and methods. three-wall intra-bony periodontal defects...
