摘要：
采水蒸气蒸馏法提取大蒜挥发油,用毛细管气相色谱-质谱联用程序升温法测定大蒜挥发油化学成分,考察贮藏对大蒜挥发成分的影响.共鉴定出了22种化合物,占挥发油总成分的95%.主要成分为大蒜辣素(28%～41%)和甲基烯丙基硫醚(11～16%)等.结果表明不同贮藏期的大蒜油的成分的种类变化不大,但相对含量变化较大.该变化可能源自贮藏期成分的挥发和大蒜水分含量的变化.

Hollow mesoporous silica spheres;Horseradish peroxidase;Biosensor;Direct electron transfer
摘要：
In this work, novel mesoporous silica hollow spheres (MSHS) were chosen as an immobilization matrix, to construct a mediator-free third-generation HRP biosensor. UV-vis spectroscopy revealed that horseradish peroxidase (HRP) entrapped in MSHS could retain its native structure. FTIR spectroscopy and nitrogen adsorption-desorption isotherms indicated that HRP are intercalated into the mesopores. The direct electron transfer of HRP entrapped in MSHS was observed. A pair of stable and well-defined redox peaks of HRP with a formal potential of about -0.150 V (vs. Ag/AgCl) in 0.1 M pH 7.0 phosphate-buffered solution (PBS) were obtained. The biosensor exhibited a fast amperometric response to H<inf>2</inf>O<inf>2</inf> with a linear range of 3.9 ×10<sup>-6</sup> to 1.4 ×10<sup>-4</sup> M (R = 0.997, N = 20). The detection limit was 1.2 ×10<sup>-6</sup> M based S/N = 3. ©2008.

摘要：
A rapid, simple, and specific liquid chromatography-electrospray ionization-mass spectrometric method has been developed and validated for the determination of fluoxetine in human plasma. The method was validated with a linear range of 0.5-100 ng mL-1, and the lowest limits of quantification were 0.5 ng mL-1 for fluoxetine. The extraction efficiencies were about 65% and recoveries of method were in the range of 94.0-97.5%. The intraday relative standard deviation (RSD) was less than 11% and interday RSD was within 12%. The method has been successfully applied to the evaluation of pharmacokinetics and bioequivalence of fluoxetine. © Taylor & Francis Group, LLC.

摘要：
In the present paper, the gas-sensing characteristics of novel gas sensors based on PbS were investigated. The sensors exhibited high responses to NO<inf>2</inf> and NH<inf>3</inf> at room temperature. No response to other gases was observed. The response magnitude of sensors based on PbS prepared with Na<inf>2</inf>S at 50 °C was 266.4 to NO<inf>2</inf> at operating voltage 5 V. The response and recovery time was about 54 and 43 s, respectively. The response magnitude of PbS prepared with Na<inf>2</inf>S at 80 °C was about 301 to NH<inf>3</inf> at operating voltage 5 V. The response and recovery time was about 46 and 67 s, respectively. The influence of the working temperature and operating voltage on the sensor response was also studied. The sensing mechanism of the sensor was discussed. ©2009 Elsevier B.V. All rights reserved.

摘要：
Corrosion behavior of reinforced bar in concrete was studied by simulating the 4×4 array wire-beam electrode in this paper. These reinforced concretes have been coated respectively in different ways: blank, iron wire with coating resin in surface, concrete with coating resin in surface. By measuring open-circuit potential of iron wire, the impact of different ways of coating were studied on the corrosion of concrete. The result showed that it is the best protection way to coat resin on the surface of concrete, which keep the open-circuit potential within the passivation range all the time, so as to ensure the integrity of the passivation membrane.

摘要：
Supported by geographical information system, using Costanza method and referring to terrestrial ecosystem service value in China, the influence of land use and land cover change (LUCC) between 1980 and 2000 on ecosystem service value in the up and middle reaches of Dongting Lake basin was analyzed in this study. The results showed that the estimated value of ecosystem services decreased 8.416 9×10~8 CNY over a 21-year period, and the main reasons were that the land for forest use was exploited for cropland and construction land use in study area. Further analysis results showed that the value of single ecosystem service function such as gas regulation, climate regulation, soil formation and conservation, biodiversity conservation, raw materials as well as recreation decreased significantly; and that of provision of water conservation, waste treatment and food production increased obviously in the area. The results of coefficient sensitivity analysis indicated that these estimates were reliable.

摘要：
Polyethylenimine (PEI) is a type of cationic polymer which is efficient in DNA transfer. The characters of PEI binding to bovine serum albumin and human serum albumin (HSA) were described by fluorescence quenching, surface plasmon resonance (SPR) and circular dichroism (CD) spectroscopy. The fluorescence quenching results showed that the binding processes occurred on the surface of the protein molecules. The accurate binding constants between PEI and the two proteins were obtained by SPR spectroscopy. The CD spectra results showed that the confirmations of the two proteins were affected with the addition of PEI.

摘要：
Lignocellulose biomass is the new ideal feedstock for ethanol production as the renewable liquid fuel for transportation. The pivotal step of ethanol production from lignocellulose is the degradation of lignocellulosic materials to monomeric sugars through the concerted action of cellulolytic enzymes. In order to search for more efficient lignocellulose-degrading microorganisms and their enzymes, strains from humus soil samples of Gaoligong Mountains State Nature Reserve, Yunnan province, China, were isolated and purified. One of the fungal isolates YT01, with very high lignocellulose-degrading ratio and velocity, was identified as Pe´nicillium expansum. It metabolized numerous saccharides and polysaccharides, removed much of the holdbacks of lignin and hemicellulose for cellulose hydrolysis. YT01 had activity from multiple extracellular polysaccharidedegrading enzymes, including one xylanase (64 kDa), three endoglucanase (73 kDa, 43 kDa, 40 kDa), one exoglucanase (38 kDa) and one α-glucosidase (57.8 kDa). In this paper, the results showed that 69.32% cellulose, 78.66% hemicellulose and 66.22% lignin of un-pretreated rice straw were degraded after 4 days fermentation of YT01, which were much higher than the relative activities of control strains demonstrated in other reports. YT01 may have strong potential for industrial application and bio-resource utilization. Copyright ©2009 American Scientific Publishers All rights reserved.
