STUDY DESIGN A study of the histologic changes of the intervertebral discs (IVDs) in biglycan (Bgn)-deficient mice. OBJECTIVE In this study, we investigate whether the absence of Bgn accelerates the degenerative process in mouse intervertebral disc (IVD). SUMMARY OF BACKGROUND DATA Proteoglycans and collagen fibrils are major components in the(More)
Bone marrow derived mesenchymal stem cells (MSC) have been shown to be progenitor cells for mesenchymal tissues. These cells may also provide a potential therapy for bone repair. Our previous studies showed that MSC engineered with the gene for bone morphogenetic protein 2 (BMP-2), a growth factor for bone cells, were capable of differentiating into(More)
Monte-Carlo Tree Search (MCTS) is a very successful approach for improving the performance of game-playing programs. This paper presents the Accelerated UCT algorithm, which overcomes a weakness of MCTS caused by deceptive structures which often appear in game tree search. It consists in using a new backup operator that assigns higher weights to recently(More)
PURPOSE To investigate the effects of platelet-rich plasma (PRP) with fibrin matrix on the healing of intrasynovial flexor tendons in a rabbit model in vivo. METHODS We transected and repaired 156 toe flexors of 73 rabbits using the technique of Tsuge et al and a simple running epitendinous suture. We randomly assigned Repaired tendons to groups that(More)
BACKGROUND Kawasaki disease (KD) is the most common systemic vasculitis of unknown etiology in children, and can cause the life-threatening complication of coronary artery aneurysm. Although a novel treatment strategy for patients with KD-caused vascular lesions is eagerly awaited, their molecular pathogenesis remains largely unknown. c-Jun N-terminal(More)
BACKGROUND Platelet-rich plasma (PRP) can provide an assortment of growth factors, but how PRP effects bone regeneration is still unknown. The aim of the study was to explore an optimal method of using PRP and bone marrow stromal cells (BMSCs). METHODS An in vitro experiment was first conducted to determine an appropriate quantity of PRP. BMSCs were(More)
