Although the specific mechanism of neuronal damage in human immunodeficiency virus (HIV) -associated dementia is not known, a prominent role for NMDA receptor (NMDAR)-induced excitotoxicity has been demonstrated in neurons exposed to HIV-infected/activated macrophages. We hypothesized NMDAR-mediated activation of the calcium-dependent protease, calpain,(More)
A network is considered observable if its current state can be determined in finite time from knowledge of the observed states. The observability transitions in networks based on random or degree-correlated sensor placement have recently been studied. However, these placement strategies are predominantly based on local information regarding the network. In(More)
OBJECTIVES This study evaluates the microscopic characteristics of liver metastases from colorectal cancer (LMCRC) invasion and provides a reference for expansion from gross tumor volume (GTV) to clinical targeting volume (CTV). METHODS Data from 129 LMCRC patients treated by surgical resection at our hospital between January 2008 and September 2009 were(More)
A strain of transmissible gastroenteritis virus (TGEV), SHXB, was isolated in Shanghai, China. The complete genome of strain SHXB was sequenced, and its sequence was compared those of other TGEV strains in the GenBank database. The comparison showed that there were no insertions or deletions in the 5′ and 3′- non-translated regions, in the nonstructural(More)
