Strategies based on static priorities do not consider the local carrier reuse conditions, while dynamic-priority strategies do take these conditions into consideration. Intuitively, one would expect dynamic-priority strategies to perform better than static- and hybrid-priority strategies, but in the literature it is the other way around-existing dynamic-priority strategies are out-performed by some static- and hybrid-priority strategies. We propose a dynamic-priority strategy which is a significant improvement over all existing strategies. Under various traffic conditions, our simulation results indicated that the proposed strategy could reduce the call blocking/failure rate by a margin ranging from 15% to 95%

The purpose of this study was to examine whether inhibition of SPARC can regulate collagen expression in vitro and in vivo, and subsequently attenuate fibrotic stimulation by bleomycin in mouse skin and lungs.
