摘要：
The heat shock response (HSR) is an essential cellular and organismal protective mechanism against acute forms of physiological and environmental stress.In E.coli,the heat shock response to temperature upshift from 32 to 42℃ consists in induction of synthesis of more than 20 heat shock proteins and various molecular chaperones.However,there has not been a comprehensive genetic analysis of the HSR regulatory pathway,in part because traditional forward genetic screens are inadequately suited to identify genes that regulate the HSR.Here,we adapted ribosome footprinting to chloramphenicol-treated cells to generate a genome-wide translational profiling in E.coli under the condition of heat shock,and identified more than 600 previously unidentified open reading frames,which accounted for about 15% of known genes.Meanwhile,we used LC-MS to verify whether the newly identified genes expressed and explored the relationship between these new genes and the HSR.

摘要：
It is a problem on building energy efficiency of how to improve the heat insulation performance of building envelope, to make the building outer wall has good heat preservation effect, and to keep the necessary seismic performance. Exterior wall thermal insulation engineering, which is a key part on building energy conservation engineering construction quality acceptance and on building energy efficiency design, is an important part in building energy efficiency projects. Therefore, it is necessary to study the seismic performance based on the fact that the building is building energy efficiency. By the research on exterior insulation materials, the analysis on the performance of external thermal insulation materials currently used, and the research on the factors affecting the seismic performance of external thermal insulation material, It provides a guidance on evaluating the external wall thermal insulation material performance and quality, ensuring the quality of external thermal insulation material, and it is expected to achieve the effect of building energy efficiency.
摘要：
A series of studies have recently demonstrated that the release of
interleukin 1β induced by monosodium urate crystals is central to the
experimental gouty arthritis. Elaeagnus pungens has been
traditionally used for the treatment of gouty arthritis in China for more
than thousands years. However, there is still little known about the active
ingredients and mechanisms of E. pungens against gouty arthritis.
Emodinol, as a major triterpene compound in E. pungens, has been
seldom reported to have an effect on gouty arthritis. Therefore, the
potential beneficial effects and mechanisms of emodinol on gouty arthritis
were investigated in this study. Results showed that it significantly
ameliorated the hyperalgesia, inflammation, and levels of multiple
proinflammatory cytokines in monosodium urate crystals-treated mice. These
findings elucidate that emodinol exhibits a prominent effect on improving
symptoms of acute gouty arthritis induced by monosodium urate crystals
through inhibiting the generation of proinflammatory cytokines.

摘要：
Vertically aligned carbon nanotube films are good thermal interface materials because of their high thermal conductance and mechanical compliance. In this study, the authors bond carbon nanotube films and metallized silicon chips together using thermocompression method in a magnetic field to decrease the thermal contact resistance between them. Nickel is considered as the deposition metal because of its strong cohesion and good affinity on the carbon nanotube surface and it is ferromagnetic in nature. Bonding is demonstrated in vacuum chamber under the influence of temperature (300°C) and pressure (180 KPa). The resistance of the carbon nanotube film is measured with a thermal transient tester that can provide the structure function of the sample, so that people can know detailed thermal resistance. In general, the thermal contact resistance of the sample enhanced with magnetic field that the author measured is 34·24 mm<sup>2</sup>K/W that is 10% lower than the sample without enhancement. This study reveals that magnetic field can enhance the bonding strength to decrease the thermal contact resistance.<br/>
