Non-pharmacologic approaches to preserve or increase BMD include whole body vibration (WBV). A meta-analysis and one-year randomized trial concluded that WBV has no effect on BMD in older women; however, previous trials were relatively brief and did not include a sham control group. Therefore, we conducted the Vibration to Improve Bone in Elderly Subjects (‘VIBES’) trial, a randomized, sham-controlled trial of 10 min of daily WBV (0.3 g at 30 Hz) in seniors recruited...

Osteoblast-specific overexpression of amphiregulin leads to transient increase in cancellous bone mass in mice

It is well known that the epidermal growth factor receptor (EGFR), its ligands, and the structurally related receptor ERBB2/neu are expressed in skeletal cells. However, the functions of EGFR ligands in bone cells remain poorly defined. In this study, we employed a transgenic mouse line overexpressing the EGFR ligand amphiregulin (AREG) specifically in osteoblasts under the α1(I)-collagen promoter. AREG-tg mice did not show changes in body weight or gross phenotype. Compa...

Pamidronate may prevent muscle protein breakdown in burns by indirectly affecting cytokines

Jay Jason W. , Herndon David N. , Finnerty Celeste C. , Andersen Clark R. , Klein Gordon L.

We have shown that the bisphosphonate pamidronate (P) given to children <10d post-burn prevents resorptive bone loss and muscle protein breakdown. We have also shown in vitro that Ca modulates the inflammatory response by altering mononuclear cell chemokine production. We hypothesized that P affects muscle protein breakdown by altering cytokine or chemokine concentration directly or indirectly by lowering blood ionized (i) Ca. We retrospectively analysed biomarker...
