STUDY DESIGN To demonstrate the existence of mesenchymal stem cells (MSCs) in ligamentum flavum (LF) and their pathogenic role in LF hypertrophy. OBJECTIVE To isolate and characterize LF-derived MSCs and their response to transforming growth factor-beta 1 (TGF-β1) and trichostatin A (TSA), a histone deacetylase inhibitor (HDACi). SUMMARY OF BACKGROUND(More)
As the deployment of the cable TV (CATV) network becomes ubiquitous, the CATV networks have emerged as one of primary technologies to provide broadband access to the home. Due to the natural of CATV networkthe radical asymmetric bandwidth, the upstream channel is critical to allocating and scheduling. The objective of this paper is to propose a new adaptive(More)
As the community antenna television (CATV) networks becomes ubiquitous, instead of constructing an entirely new broadband network infrastructure, it has emerged as one of the rapid and economic technologies to interconnecting heterogeneous network to provide broadband access to subscribers. How to support ubiquitous real-time multimedia applications,(More)
