BACKGROUND Osteoporotic structural damage and bone fragility result from reduced bone formation and increased bone resorption. In a phase 2 clinical trial, strontium ranelate, an orally active drug that dissociates bone remodeling by increasing bone formation and decreasing bone resorption, has been shown to reduce the risk of vertebral fractures and to increase bone mineral density. METHODS ...

Ankylosing spondylitis (AS) is an inflammatory disease characterized by excessive bone formation. We investigated the presence of neutrophil extracellular traps (NETs) in AS and how they are involved osteogenic capacity marrow mesenchymal stem cells (MSCs) through interleukin-17A (IL-17A). Peripheral neutrophils sera were obtained from patients with active healthy controls. NET formation neutro...

This study was designed to determine if macrophage inhibitory protein-1 alpha (MIP-1 alpha), a recently described osteoclast (OCL) stimulatory factor,(1) was present in marrow from patients with multiple myeloma (MM) and possibly involved in the bone destructive process. MIP-1 alpha, but not interleukin-1 beta (IL-1 beta), tumor necrosis factor-beta (TNF-beta), or interleukin-6 (IL-6), messenge...

Distraction osteogenesis (DO) is one of the most dramatic in vivo applications of mechanical stimulation as a means of inducing bone regeneration. A simple and reproducible murine model of tibia distraction osteogenesis was developed using a monolateral fixator. Bone formation was assessed histologically over a 35-day time course. The steady state expression of a broad family of angiogenesis-as...

conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...

The rate of calcification of new bone (accretion rate) was measured by a radioisotope technique in 20 patients with carcinoma of the breast, 14 patients with multiple myelomatosis, five patients with Paget's disease of bone, and in six patients with solitary, non-osseous tumours. The rate of bone destruction was assessed in these patients by the measurement of the rate of urinary calcium excret...

introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...

BACKGROUND Active vitamin D metabolites have been shown to have protective effects in experimental arthritis especially when used as preventive treatment. However, because the direct effects of 1,25-dihydroxyvitamin D3 (1,25(OH) 2D3) on bone formation and resorption are very complex, the net effect of 1,25(OH)2D3 on histomorphometric parameters of bone turnover and mineralisation should be inve...
