Streptococcus suis serotype 2 (SS2) is a porcine and human pathogen with adhesive and invasive properties. The absence of suitable vaccine or virulent marker can be the bottleneck to control SS2 infection. In the present study, a novel immunogenic Enolase identified in the previous study was inducibly overexpressed in Escherichia coli, and the purified(More)
To improve the scalability of Gnutella-like unstructured peer-to-peer (P2P) networks, a uniform index caching (UIC) mechanism was suggested in some earlier work. In UIC, query results are cached in all peers along the inverse query path such that the same query of other peers can be replied from their nearby-cached results. However, our experiments show(More)
Peer-to-peer networks are widely criticized for their inefficient flooding search mechanism. Distributed hash table (DHT) algorithms have been proposed to improve the search efficiency by mapping the index of a file to a unique peer based on predefined hash functions. However, the tight coupling between indices and hosting peers incurs high maintenance cost(More)
Stem cell therapy has recently been introduced to treat patients with type 2 diabetes mellitus (T2DM). However, no data are available on the efficacy and safety of allogeneic Wharton’s Jelly-derived mesenchymal stem cell (WJ-MSC) transplantation in patients with T2DM. Here we performed a non-placebo controlled prospective phase I/II study to determine(More)
The present paper studied the effect and mechanism of neurosteroid pregnenolone sulfate (PREGS) on spontaneous glutamate release using electrophysiological and biochemical methods combined with a pharmacological approach. The results suggested that PREGS had a selective enhancing effect on spontaneous glutamate release in the prelimbic cortex and the(More)
Many research activities on wireless sensor networks (WSNs) need detailed performance statistics about protocols, systems, and applications; however, current simulation tools and testbeds lack mechanisms to report these statistics realistically and conveniently. To address this need, we have developed a WSN emulator, VMNet. VMNet emulates networked sensor(More)
Network research generally requires a simulation or emulation environment to test protocol implementations, to evaluate the performance of a scheme or a system, and to study complicated and highly varying network operations. For large network simulation, simulators consume a large amount of time and memory; and its result is largely based on some modeling(More)
