Many experiments support the notion that augmentation of neurotrophic factors' (NTFs) activity, especially glial cell line-derived neurotrophic factor (GDNF) and brain-derived neurotrophic factor (BDNF) could prevent or halt the progress of neurodegeneration in Parkinson's disease (PD). However, application of NTFs as therapeutic agents for PD is hampered(More)
Objective. To investigate the current use of integrative therapies (IT) in the treatment of patients with amyotrophic lateral sclerosis (ALS). Methods. A cross-sectional, multicenter clinical epidemiological survey was conducted in 12 hospitals in Shanghai. We investigated the type and frequency of IT use and determined whether the use of IT correlated with(More)
Stream-media technology is a hotspot of research these days. The performance of stream-media service provided by the Internet based on TCP/IP protocol is always changing with the variation of network and is easily affected by the network parameters. During the developing of stream media, service performance Measurement is very important. This paper proposes(More)
Analyzing the characteristic of network behavior provides scientific basis for designing, building, and managing the next generation Internet, and is especially important for monitoring network behavior. This paper establishes a system of metrics that evaluates the behavior of IP networks with respect to the need of analyzing network behavior, introduces(More)
IP networks are more and more used to transport real-time services. A crucial factor for real-time services is the end-to-end delay experienced by the application. The contribution resulting from the queuing delay induced by the network nodes is the most difficult to calculate. Under assumptions of real-time traffic behaviors and network nodes behaviors,(More)
