It is difficult to study bone in vitro because it contains various cell types that engage in cross-talk. Bone biologically links various organs, and it has thus become increasingly evident that skeletal physiology must be studied in an integrative manner in an intact animal. We developed a model using local intraosseous small interfering RNA (siRNA)(More)
Three-dimensional porous titanium alloys printed via electron beam melting have low stiffness similar to that of cortical bone and are promising scaffolds for orthopedic applications. However, the bio-inert nature of titanium alloy is poorly compatible with bone ingrowth. We previously observed that simvastatin/poloxamer 407 thermosensitive hydrogel induces(More)
To compare the efficacy of once-weekly and once-daily subcutaneous injections of teriparatide (recombinant human parathyroid hormone 1-34) on fracture healing, 50 adult male Sprague-Dawley rats were subjected to a unilateral tibia fracture and received internal fixation with a Kirschner needle. Based on the injection dose and frequency, the rats were(More)
Researching on the power supply path is one aspect of analyzing gird physics topology structure, the paper aims to discuss the power supply paths which would describe the power supply process from a certain source, based on power components theory. In general, path search method is divided into depth-first search and breadth-first search. Improving on the(More)
Treating peripheral nerve defects represents a clinical challenge, and nerve conduits lacking an internal scaffold lead to limited large nerve gap regeneration. Here, we bridged 10-mm sciatic nerve defects in rats with a chitosan conduit filled with 0, 0.5, or 1.0 mg of simvastatin in Pluronic F-127 hydrogel. We assessed subsequent nerve regeneration using(More)
