The effect of continuous infusion of human parathyroid hormone on bone architecture in female mice
… for either 2 week or 4 week duration. Total body bone mineral density (BMD) and bone mineral content (BMC), trabecular and cortical bone microarchitecture, and serum calcium levels were measured. There were no significant differences in BMD or BMC in either study in mice infused with either …

Skeletal adaptation to reduced mechanical loading
Bone adapts its mass and architecture in response to its mechanical environment. Yet control of this process by mechanical cues is poorly understood, particularly for unloading. Defining the fundamental mechanoregulation of bone adaptation is critical for the better understanding and mitigation of …

Skeletal adaptation to reduced mechanical loading
Bone adapts its mass and architecture in response to its mechanical environment. Yet control of this process by mechanical cues is poorly understood, particularly for unloading. Defining the fundamental mechano-regulation of bone adaptation is critical for the better understanding and mitigation of …

Study and development of ultrasound monitoring of skeletal defects
Fatigue fractures are fine disruptions of normal bone architecture whose identification is often unreliable or difficult using x-rays (Robinson, Wilson et al.; Kundel 2004; Swischuk and Hernandez 2004). A fatigue fracture results from the application of abnormal loads to a bone with normal elastic …

Δυναμική ταξινόμηση των μορφών της νόσου του Paget των οστών και η θεραπευτική αντιμετώπισή τους
… the traditional radiological phases of bone turnover or remodelling: that is, the osteolytic phase, the mixed phase, and the osteoblastic phase. Normal or diminished bone scan activity in the osteoblastic phase indicates diminished bone turnover which we distinguish as the osteosclerotic …

Thermoneutral Housing Did Not Impact the Combined Effects of External Loading and Raloxifene on Bone Morphology and Mechanical Properties in Growing Female Mice
… and increasing the bound water content in the bone matrix in a cell-independent manner. In this thesis, active tissue formation was induced by non-invasive external tibial loading in female mice and combined with raloxifene treatment to assess their combined effect on bone morphology and …

Pathologic Fracture Secondary to Acute Hematogenous Osteomyelitis in Children in New Zealand
… of osteomyelitis may weaken and destabilize the bone architecture leading to complications like pathologic fracture. The purpose of this study was to investigate the risk factors for the development of pathologic fracture following acute hematogenous osteomyelitis for children in New Zealand. …

NEAR INFRARED SPECTROSCOPIC ASSESSMENT OF BONE WATER BINDING TO COLLAGEN AND MINERAL
Cortical bone fragility increases with age, therapeutic drug use and disease states. Clinically, bone fragility is evaluated by assessment of bone mineral density (BMD); however, studies have shown that other factors such as bone architecture, cell turnover and tissue composition influence bone …

Bone Properties of Recombinant Inbred Line - BXD Mouse
<p>Osteoporosis is identified by reduced bone mass, decreased bone quality and altered bone micro-architecture. These traits are quantitative and also highly regulated by genetic and environmental factors. As a powerful tool for collaborative analysis of quantitative traits and gene function, BXD …

Advanced Magnetic Resonance Imaging of Osteoarthritis
… of change. Moving to QIBs of subchondral bone, I evaluate the association between measures of subchondral bone architecture derived from MR texture analysis and OA progression in the Osteoarthritis Initiative. The remainder of the thesis describes a prospective observational study where …

Automated Modelling of Cortical Bone from Clinical CT
… providing an improved measure of the cortical bone mineral density (cBMD) from in-vivo clinical CT scans. These features are of interest as both have been linked to fracture risk. \\ The new technique is developed within the cortical bone mapping (CBM) framework so that it provides localised …

Osseointegration of a Cementless Total Knee Arthroplasty in a Murine Model of Glucocorticoid Induced Osteoporosis
… deficient osteoblast activity (i.e., decreased bone formation) rather than increased osteoclastic activity. Glucocorticoid-type steroids (GC) are used long-term typically for inflammatory diseases such as rheumatoid arthritis, lupus, multiple sclerosis, and other autoimmune disorders. …

Influence of Biomaterials in Alveolar Bone Regeneration and Preservation
… documented. However, they require a minimal bone quantity (in height and thickness). But alveolar bone defects are very frequent, for instance due to periodontitis, traumatism or acute dental infection. Moreover, a simple tooth extraction leads to significant bone resorption. Therefore, …

Dietary protein and bone health: Harmonizing conflicting theories
… sources of fixed acid cause demineralization of bone and apparent osteoporosis, this effect has not been consistently observed for protein, suggesting opposing, beneficial effects on bone. Specifically, protein may improve bone health through improving calcium absorption, increasing total …

Could a Foot Pressure Platform Replace X-ray to Diagnose Hallux Valgus Deformity?
