Lanthanide ions have been proven to have various biologic effects. Lanthanum with extremely active physical and chemical property was evidenced to possess antibacterial and immune adjustment effects. In the present study, the anti-inflammatory effects of lanthanum chloride (LaCl 3) on lipopolysaccharide (LPS)-challenged mice were examined in vivo and in vitro. The results indicated that LaCl 3 can greatly decrease the secretion of tumor necrosis factor alpha (TNF-α) and interleukin (IL)-1β as well as TNF-α mRNA expression in the mice challenged with LPS. To clarify the mechanism involved, the effects of LaCl 3 on the activation of nuclear factor (NF)-κB were examined both in liver and in peritoneal macrophages. The LPS-induced activation of NF-κB was significantly blocked by LaCl 3. These findings demonstrate that the inhibition of the LPS-induced inflammatory media, such as TNF-α and IL-1β, by LaCl 3, is due to the inhibition of NF-κ B activation. © Springer Science+Business Media, LLC 2010.

This paper analyses main factors influencing CET4 passing-rate after investigating some classes and reducing related factors based on rough set to find out the core factor and minimum reduction, and then sets up forecasting model of low passing rate with ANN. In virtue of this situation, to switch original post-controlling into pre-controlling in general academy is expected to avoid low passing-rate in maximum. ©2010 IEEE. Source

In this paper, we propose a real-time advertising solution based on MANET for equipment failure information, and provide a fairly detailed description of the development of a distributed sensing and visualization system of equipments failures. The system consists of clients, middle nodes and central server, and includes such subsystems as failure information generator, failure information transfer, routing protocol, distributed sensing and visualization system based on geographical information system (GIS). Experiments demonstrate that the system can advertise the failure information in a timely way and provide rich inquiry functions and real-time situation display. © 2012 Springer-Verlag GmbH. Source

In higher eukaryotes ribosome production starts at the end of mitosis, increases during G1, is maximal in G2 (. Sirri et al., 2000) and stops during prophase (. Gébrane-Younès et al., 1997). But the mechanism of the change is still uncovered. Especially in the actively growing mammalian somatic cells usually contain one or several giant fibrillar centres (GFCs) with many tiny fibrillar centre (FCs) (. Koberna et al., 2002; RaŠka et al., 2004; Casafont et al., 2007). The process how the giant fibrillar centre (GFC) and the many tiny fibrillar centres (FCs) were formed is unknown. The present results showed there were processes of FCs fusion in G1 phase and FCs regeneration in S phase respectively in the nucleoli of A 375 cells. A few FCs fused each other in late G1 phase when the process of nucleoli fusion was completed. In S phase, a lot of tiny FCs were regenerated from the periphery of GFC, separated and scattered into nucleolar matrix in late S phase and early G2 phase. The GFC was found to be coexisted with numerous tiny FCs in the nucleolus in G2 phase. The present study provided a new evidence of nucleolar dynamic change during interphase: fibrillar centre (FC) was not to be a stable state subunit of nucleolar compartment but a highly dynamic process that may be the bases of nucleolar morphological architecture organization and its function taking place. © 2013 Elsevier Ltd.

Motivation is important for studying English; the teacher should have positive expectation on the students. The English studying interest of the students is aroused by singing English songs and setting the studying goals for the students. The following steps are used to improve the interest of studying English: instruct them the strategies of studying, guide the students to choose the contents of studying, direct them to practice speaking English, conduct them to learn the vocabulary and the text, and guide them to study English outside the classroom. The multiple equipment should be sufficiently used with reason and feedback exactly on time so as to arouse the students' motivation in English teaching. © 2013 Springer-Verlag. Source
