Adenovirus 36 (Ad36) is the only adenovirus to date that has been linked with obesity in humans. Our previous studies in late-adolescent females suggest that excess weight in the form of fat mass is associated with lower cortical bone strength. The purpose of this study was to assess the relationship between Ad36-specific antibodies, adiposity, and bone strength in our sample of late-adolescent...

OBJECTIVES To examine association between muscle strength, jump test performance, muscle mass, bone mineral density (BMD), and bone strength in older adults. METHODS Sixty individuals (55-75 years) participated. Leg press strength and bilateral hip abduction strength were evaluated by one repetition-maximum testing. Jump power (JPow) and jump height (JHt) were assessed by jump test performanc...

objective(s): adipose derived stem cells (adscs) can be engineered to express bone specific markers. the aim of this study is to evaluate repairing tibia in animal model with differentiated osteoblasts from autologous adscs in alginate scaffold. materials and methods: in this study, 6 canine’s adscs were encapsulated in alginate and differentiated into osteoblasts. alkaline phosphatase assay (a...

Modern cementing techniques aim to improve the interlock between bone and cement and to establish a durable interface. Cement penetration is generally believed to influence interface failure, but current methods for improving the cement-bone interface are inadequate. Oscillation is the reciprocated movement of an object through its balanced position, or the quantum physics of systematic fluctua...

The benefit of impact-loading activity for bone strength depends on whether the additional bone mineral content (BMC) accrued at loaded sites is due to an increased bone size, volumetric bone mineral density (vBMD) or both. Using magnetic resonance imaging (MRI) and dual energy X-ray absorptiometry (DXA), the aim of this study was to characterize the geometric changes of the dominant radius in ...

INTRODUCTION Structurally intact cancellous bone allograft is an attractive tissue form in that it may be filled with osteoinductive agents while providing immediate structural support. Bone allograft tissue is commonly submitted to gamma radiation sterilization of 25-35 kGy to prevent disease transmission from donor to host. In cortical bone, gamma radiation sterilization has been shown to cau...
