摘要：
The aim of this paper is to develop a wireless magnetoelastic sensing method for the determination of uranium in water based on the inhibitory effect of uranyl cation to α-amylase. In this method, a wireless sensor used for detecting uranium was fabricated by immobilizing a layer of starch gel on the surface of a magnetoelastic foil. When the sensor was in a solution containing α-amylase, the α-amylase catalyzed the hydrolyzation of starch, causing a resonance frequency shift of the sensor. Meanwhile, the catalytic hydrolyzation of starch was inhibited by uranium presented in the above solution, resulting in a decrease in the resonance frequency shift of the sensor. Consequently, the amount of uranium could be determined by measuring the resonance frequency shift. The influence of manifold variables on the determination was investigated in details. A linear range was found to be 9.2 to 103.5 μg L<sup>-1</sup> under optimal conditions with a detection limit of 3.6 μg L<sup>-1</sup>. The method was applied to the determination of uranium in environmental water samples with satisfactory results. ©2013 Copyright Taylor and Francis Group, LLC.

摘要：
This paper researched the effect of six surfactant including aodium dodecyl benzene sulfonate(SDBS), cetyltrimethyl ammonium bromide(CTAB), po1yoxyethylene octylphenol ether (OP-10), Triton X-100(TX-100), FSO and their mixture on surface tension of the leaching solution and on leaching rate of uranium in sandstone uranium ores. Results showed that all kinds of surfactant could observably reduce the surface tension of the leaching solution at low concentration. The surface tension of leaching solution containing 1g/L FSO and 0.01g/L mixture surfactant(mOP-10 /mFSO; 7:3) was 20.7mN/m and 17.9 mN/m respectively. Results of agitation leach experiments showed that FSO and the system of OP-10 and FSO could improve the leaching rate, and the leaching rate of uranium could be increased by 14.16% and 16.08% to 92.54% and 94.09% respectively. These results indicated that the way of reducing the surface tension of the leaching solution could improve the leaching rate of uranium. © (2013) Trans Tech Publications, Switzerland.

摘要：
Exposure of cells to densely ionizing radiation can initiate a series of molecular and cellular events, which result in the gain and loss of functions in critical regulatory genes and cellular damage. In the present study, alpha-particle radiation-induced insulin resistance and toxic injury to 3T3- L1 preadipocyte were observed, and the mechanism underlying the action was investigated. 3T3-L1 preadipocytes were irradiated by different doses of alpha-particle at 0Gy , 0.3Gy , 0.6Gy , 1.0Gy , 1.5Gy , 2.0Gy , and 4.0Gy . Cloning efficiency was investigated to evaluate the cellular toxic effect of alpha-particle irradiation on cellular viability. Cytokinesis-block micronucleus technique ( CB-MNT ) and single-cell comet assay COMET assay were used to observe alpha-particle irradiation-induced DNA damage. Expression of caveolin-1, IRS-1 (insulin receptor substrate-1 ) and GLUT-4 ( glucose transporter-4 ) were analyzed by western blot and Reverse-transcription PCR (RT-PCR). Alpha-particle irradiation inhibited cloning efficiency, and increased micronucleus cells and the DNA damage in 3T3-L cells in a dose-dependent manner. Alpha-particle irradiation decreased the mRNA expression of GLUT-4 and IRS-1, and inhibited the protein expression of caveolin-1. The present results indicate that alphaparticle irradiation induced toxic injury and insulin resistance in 3T3-L1 preadipocyte, which might be associated with inhibition of GLUT-4 and IRS-1 expression by down-regulating caveolin-1. ©2013 Trade Science Inc. - INDIA.

摘要：
Although with a distinct heme active site, both myoglobin (Mb) and cytochrome c oxidase (CcO) were found to function as a nitrite reductase (NIR) under hypoxic conditions. On the other hand, Mb was rationally designed to mimic native CcO by introduction of two distal histidines, i.e., L29H/F43H mutant, where His29, His43 and native His64 formed a metal-binding site. To probe the role of distal histidines in regulating the NIR activity of Mb, we herein designed a single mutant of L29H Mb that contains two distal histidines and solved its X-ray crystal structure, then we made both structural and NIR activity comparisons of Mbs with one to three distal histidines. It was shown that introduction of one or two additional distal histidines in Mb leads to the formation of a distal hydrogen network, which slightly alters the conformation of heme active site and inhibits the NIR activity. Meanwhile, the reductase activity of both L29H Mb and L29H/F43H Mb are regulated by metal ions such as Cu(II) or Zn(II) binding to the distal histidines, i.e., Cu(II) enhances the reactivity while Zn(II) inhibits the reactivity. These findings provide valuable insights into the structure and function relationship for both Mb and CcO functioning as a NIR in biological system.

摘要：
We have prepared a nanoparticle-based metronidazole-imprinted polymer by combining a surface molecular imprinting technique with a sol-gel process. Metronidazole was used as a template, 3-aminoprophyltriethoxysilane as the functional monomer, and tetraethyl orthosilicate as the cross-linker. The resulting magnetic molecularly imprinted polymer was characterized by Fourier transform infrared spectroscopy, powder X-ray diffraction and scanning electron microscopy. The adsorbent can be applied to the solid phase extraction of metronidazole and exhibits high adsorption capacity, good selectivity, favorable reusability and the feature of magnetic separation. The binding performances of the adsorbent were evaluated by equilibrium rebinding experiments and Scatchard analysis. The material was successfully applied to solid phase extraction of metronidazole, followed by spectrophotometric determination in food samples. Spiked recoveries ranged from 88.5% to 97.0%, with relative standard deviation (RSD) of <3.5% for milk samples, and of 85.6% to 96.0% (with RSDs of 3.3-4.5%) for honey samples. © The Royal Society of Chemistry 2013.

摘要：
The solvothermal reaction of Cd(NO 3 ) 2 with substituted phenyl-dicarboxylic acids afford four coordination polymers formulated as [Me 2 NH 2 ] 2 [Cd(2-R-BDC)] ·xDMF (2-R-BDCH 2 , R = -H, -NH 2 , -Br, -NO 2 ), which feature interpenetrated dia or qtz nets based on Cd(COO) 4 tetrahedral secondary building units. The size of the substituent group plays a key role in the formation of the chirality and catenation of nets: the small ones lead to three-fold interpenetrated achiral dia nets while the larger ones furnish two-fold interpenetrated chiral qtz nets. © 2013 This journal isThe Royal Society of Chemistry.

摘要：
In this study, infrared thermography is used to detect the thermal effects of rubber-like materials during loading-unloading cycles. Two salient features of temperature change have been observed: (1) the temperature has a tiny decrease at first and then becomes to increase during the stretching process, which is in agreement with the thermo-elastic inversion effect. (2) Temperature variation is partly reversible in the first cycle and totally reversible in the following cycles. These phenomena are related to complicated deformation mechanisms. Based on the analysis of elastic thermal effects during deformation process, thermodynamics of rubber elasticity has also been investigated by infrared thermography. ©2012 Springer-Verlag.
