Emerging evidence recently indicates that the anterior cingulate cortex is critically involved in the central processing and modulation of noxious stimulus, although the neuroadaptation in the anterior cingulate cortex has not been well documented in the conditions of chronic pain. Meanwhile, the cellular mechanism underlying opiate analgesia in the anterior cingulate cortex remains unclear. To address these issues, the present study was undertaken to explore the adaptation of excitatory glutamatergic transmission and mu opioid receptor-mediated modulation of glutamatergic transmission in the anterior cingulate cortex slices from the complete Freund′s adjuvant (CFA)-inflamed rats. The results demonstrated that glutamatergic paired-pulse facilitation was decreased in the anterior cingulate cortex neurons from the CFA-inflamed rats, indicating an enhanced presynaptic glutamate release. In addition, activation of mu opioid receptor significantly inhibited the glutamatergic excitatory postsynaptic currents (EPSCs) in the anterior cingulate cortex neurons, which was attained through the suppression of presynaptic glutamate release. Taken together, these findings provided the evidence for the functional adaptation of central glutamatergic transmission induced by peripheral inflammation, and elucidated the cellular mechanism underlying opiate analgesia in the anterior cingulate cortex. © 2009 Elsevier B.V.

Knowledge spillover not only has economies of scale, but also has economies of scope in scientific research collaboration. The paper set out to provide a framework of mechanism design of synergies gained from knowledge alliance made up of library consortium and R&D institutions. Firstly, it proposed that the formation the knowledge cooperation was mainly due to complementary resource advantages achieving, cost and risk sharing, and mutual learning. Secondly, it analyzed relational game in the knowledge alliance cooperation relations and proposed a conceptual model. Lastly, the paper put forward a relational mechanism which provided a theoretical reference for R&D institutions to enhance their knowledge alliance partnership. © 2017 The Authors.

In this paper, the consensus problem of multi-agent following a leader is studied. An adaptive design method is presented for multi-agent systems with non-identical unknown nonlinear dynamics, and for a leader to be followed that is also nonlinear and unknown. By parameterizations of unknown nonlinear dynamics of all agents, a decentralized adaptive consensus algorithm is proposed in networks with jointly connected topologies by incorporating local consensus errors in addition to relative position feedback. Analysis of stability and parameter convergence of the proposed algorithm are conducted based on algebraic graph theory and Lyapunov theory. Finally, examples are provided to validate the theoretical results. © 2012 Elsevier Ltd. All rights reserved.

In order to further design and successfully prepare for the functional metal-organic framework materials, it is essential to understand the fundamental correlations between the composition, physical properties and topology of the underlying nets. In this review, we focus on recent advances in metal-organic frameworks (MOFs) that possess more common non-zeotype 4-connected topological nets (such as sql, kag, nbo, lvt, cds, qtz, dia, lon, pts, etc.), and discuss the synthetic strategies of non-zeotype 4-connected MOFs and their related properties. In particular, we emphasize how to establish basic design principles and synthetic methodology to construct the same topological MOFs with different functions using specifically designed organic linkers. © 2013 Elsevier B.V.

A novel dry thermal sulfuration approach has been used to fabricate a porous NiS/Ni nanostructured cathode electrode. Galvanostatic battery testing shows that the NiS/Ni electrode exhibits high discharge/charge capacity and excellent cycle performance. The performances are due to its favorable porous structure and the fine electrical contact between NiS and Ni. © 2012 The Royal Society of Chemistry.

Tupistra chinensis Baker has been used as a folk remedy in China, and it has been shown to exhibit anti-inflammation, expectorant and anti-bacterial effects. In this study, we report the cytotoxic activity of the total saponins of Tupistra chinensis Baker (TST) against several carcinoma cell lines, including A549, MCF-7 and HeLa cells with the IC50 values of 4.11 μg/ml, 6.47 μg/ml and 7.78 μg/ml respectively. Treatment of A549 cells with TST resulted in growth inhibition and induction of apoptosis in a time-dependent manners determined by cell viability, chromatin condensation, DNA fragmentation and flow cytometry analysis. The activities of caspase-3, 9 were significantly increased following TST treatment. Real-time PCR analysis showed that the mRNA expression levels of pro-apoptosis related genes including Bax, P21, P27 and P53 were markedly increased in the cells treated with TST but anti-apoptosis related gene Bcl-2 was slightly decreased. TST also leads to a loss of mitochondrial membrane potential in a time-dependent manner the release of cytochrome C from mitochondria into the cytosol. Thus, these results suggest that TST may play an important role in tumor growth suppression by inducing apoptosis in human A549 cells via mitochondria-dependent apoptotic pathways and the TST would be promising to treat human lung adenocarcinoma.

Ultrahigh-temperature (UHT) and high pressure (HP) metamorphic rocks generated at different times in Earth history form paired suites within the same tectonic belts in several regions. We evaluate the thermal regimes and fluid circulation patters in different plate tectonic settings and propose a new model involving ridge subduction where the slab window places hot asthenosphere against the base of the overlying plate and provides an ideal setting for the supply of heat and CO2-rich fluids at relatively shallow domains, which can explain the formation and preservation of UHT metamorphic rocks in the roots of the arc and forearc. The plate geometry below the slab window would inhibit the normal cooling induced by the slab, and a temporary deprivation of slab-derived sediments and hydrous fluids. Our analysis provides a unified model for paired UHT and HP metamorphic orogens and presents a key to the associated thermal and fluid regimes. © 2009 Blackwell Publishing Ltd.

The geometry and timing of amalgamation of the North China Craton have been controversial, with three main models offering significantly different interpretations of regional structure, geochronology, and geological relationships. One model suggests that the Eastern and Western Blocks of the NCC formed separately in the Archean, and an active margin was developed on the Eastern Block between 2.5 and 1.85. Ga, when the two blocks collided above an east-dipping subduction zone. A second presumes the Eastern Block rifted from an unknown larger continent at circa 2.7. Ga, and experienced a collision with an arc (perhaps attached to the western block) above a west-dipping subduction zone at 2.5. Ga, and the 1.85. Ga metamorphism is related to a collision along the northern margin of the craton when the NCC joined the Columbia supercontinent. A third model suggests two collisions in the Central Orogenic Belt, at 2.1 and 1.88. Ga, but recognizes an early undated deformation event. Recent seismic results reveal details of the deep crustal and lithospheric structure that support both the second and third models, showing that subduction beneath the Central Orogenic Belt was west-directed, and that there is a second, west-dipping paleosubduction zone located to the east of the COB dipping beneath the Western Block (Ordos Craton). The boundaries identified through geophysics do not correlate with the boundaries of the Trans-North China Orogen suggested in the first model, and the subduction polarity is opposite that predicted by that model. High-pressure granulite facies metamorphism at 1.85. Ga is not restricted to the "TNCO" as suggested by the first model, but is documented across the NCC, as predicted by the second model, suggesting a major continent-continent collision along the north margin of the craton at 1.85. Ga. Further, it has recently been shown that in the southern "TNCO", there is no record of metamorphism at circa 1.85. Ga, but only at 2.7-2.5. Ga, showing that the "TNCO", as defined as a circa 1.85. Ga orogen, does not exist. This is further confirmed by recent Re-Os isotopic studies which show that the subcontinental lithospheric mantle beneath the southern COB is late Archean in age, and that a province in the northern NCC is circa 1.8. Ga, correlating with the proposed collision belt of the NCC with the Columbia supercontinent across the entire NCC. The COB is an Archean convergent belt, re-worked in the Paleoproterozoic, and the Paleoproterozoic tectonism is widespread across the NCC, as predicted by the model whereby the previously amalgamated Eastern and Western Blocks experienced a continental collision with Columbia at circa 1.85. Ga, but uplift/exhumation rates are slow, necessitating a re-evaluation of the tectonic models of the NCC. © 2011 International Association for Gondwana Research.
