The accelerated effect of recombinant human bone morphogenetic protein 2 delivered by β-tricalcium phosphate on tendon-to-bone repair process in rabbit models.

Background: Bone morphogenetic protein 2 (BMP-2) plays an important role in the tendon-to-bone repair process. However, there is no previous literature on acceleration of the tendon-to-bone repair process by BMP-2 delivered by β-tricalcium phosphate (β-TCP). The aim of this study was to investigate the accelerated effect of recombinant human BMP-2 (rhBMP-2) delivered by β-TCP on the tendon-to-bone repair process.

Uhrf1 is indispensable for normal limb growth by regulating chondrocyte differentiation through specific gene expression.

Transcriptional regulation can be tightly orchestrated by epigenetic regulators. Among these, ubiquitin-like with PHD and RING finger domains 1 (Uhrf1) is reported to have diverse epigenetic functions, including regulation of DNA methylation. However, the physiological functions of Uhrf1 in skeletal tissues remain unclear.

Local co-application of zoledronate promotes long-term maintenance of newly formed bone induced by recombinant human bone morphogenetic protein 2.

Bone Morphogenetic Proteins (BMPs) strongly induce the recruitment and differentiation of mesenchymal progenitor cells into mature osteoblasts, but also directly and indirectly stimulate differentiation of osteoclast progenitor cells and acceleration of mature osteoclasts function leading excessive bone resorption. Bisphosphonates, such as zoledronate (ZOL), inhibit osteoclasts function and osteoclasts mediated bone resorption. The short or middle term effect of BMPs and bisphosphonates on bone formation were previously reported, but there was no study that argue about the long term effect of bisphosphonates on BMP-induced bone anabolism.

[Compartment syndrome in bilateral lower legs after total cystectomy: a case report].

We report a case of compartment syndrome in bilateral lower legs after total cystectomy with urethrectomy and ileal conduit diversion. A 64-year-old man who had diabetes mellitus for 20 years underwent an operation for invasive bladder cancer. He was placed in the lithotomy position and both lower legs were protected with an elastic stocking and intermittent pneumatic compression for prevention of deep vein thrombosis during the operation.
