Monitoring the concentration of antibiotics in body fluids is essential to optimizing the therapy and minimizing the risk of bacteria resistance,which can be made with electrochemical sensors tailored with appropriate *** this paper,we report on sensors made with screen-printed electrodes(SPE)coated with fullerene(C60),reduced graphene oxide(rGO)and Nafion(NF)(C60-rGO-NF/SPE)to determine the antibiotic metronidazole(MTZ).Under optimized conditions,the C60-rGO-NF/SPE sensor exhibited a linear response in square wave voltammetry for MTZ concentrations from 2.5×10^(-7) to 34×10^(-6) mol/L,with a detection limit of 2.1×10^(-7) mol/*** sensor was also capable of detecting MTZ in serum and urine,with recovery between 94%and 100%,which are similar to those of the standard chromatographic method(HPLC-UV).Because the C60-rGO-NF/SPE sensor is amenable to mass production and allows for MTZ determination with simple principles of detection,it fulfills the requirements of therapeutic drug monitoring programs.

Polycrystalline Pr2Fe17-xMnx（x = 0, 1, and 2）alloys were studied by X-ray diffraction（XRD）, heat capacity, ac susceptibility, and isothermal magnetization measurements. All the alloys adopt the rhombohedral Th2Zn17-type structure. The Curie temperature increases from 283 K at x = 0 to 294 K at x = 1, and then decreases to 285 K at x = 2. The magnetic phase transition at the Curie temperature is a typical second-order paramagnetic–ferromagnetic transition. For an applied field change from0 to 5 T, the maximum-△SM for Pr2Fe17-xMnxalloys with x = 0, 1, and 2 are 5.66, 5.07, and 4.31 J·kg^-1·K^-1,respectively. The refrigerant capacity（RC） values range from 458 to 364 J·kg^-1, which is about 70 %–89 % that of Gd. The large, near room temperature △SM and RC values,chemical stability, and a high performance-to-cost ratio make Pr2Fe17-xMnxalloys be selectable materials for room temperature magnetic refrigeration applications.

After a radiological or nuclear event, acute radiation syndrome(ARS) will present complex medical challenges that could involve the treatment of hundreds to thousands of patients. Current medical doctrine is based on limited clinical data and remains inadequate. Efforts to develop medical innovations that address ARS complications are unlikely to be generated by the industry because of market uncertainties specific to this type of injury. A prospective strategy could be the integration of cellular therapy to meet the medical demands of ARS. The most clinically advanced cellular therapy to date is the administration of mesenchymal stem cells(MSCs). Results of currently published investigations describing MSC safety and efficacy in a variety of injury and disease models demonstrate the unique qualities of this reparative cell population in adapting to the specific requirements of the damaged tissue in which the cells integrate. This report puts forward a rationale for the further evaluation of MSC therapy to address the current unmet medical needs of ARS. we propose that the exploration of this novel therapy for the treatment of the multivariate complications of ARS could be of invaluable benefit to military medicine.

本论文中,我们采用跨样本熵值法来调研2004-2011年间市场和行业层面国际股票收益的发展。2007/2009年度全球金融危机用作案例研究。我们探究了中国大陆,香港,德国,日本,英国和美国8个市场指数下2004-2011年间的的每日数据。与此同时,我们计算了从8个分区（基本材料,金融,医疗,技术,消费品,工业品,服务以及综合部门）选取的8支股票两两之间道琼斯工业平均指数的交互关系。SampEn（样本熵）可靠区间的计算方法延伸到cross-SampEn（跨样本熵）。2004-2007期间（全球金融危机前）以及2008-2011（全球金融危机后）每两支股票之间的cross-SampEn以及可靠区间也计算了。样本计算方法用在选取的证券指数中。结果表明这些市场指数的cross-SampEn在全球金融危机后减小,这暗示较低的不同时性（与金融危机有相关性）。与此同时,结果也表明基于股市安排（如基于最紧密关系选取的股票）每两支证券指数收益序列在全球金融危机后升高,这暗示了较高不同时性（与金融危机的相关性较小）,然而,另一方面,基于最差关联性的证券指数,金融危机后收益序列降低,表明较高不同时性（与金融危机有相关性）。比较相关系数以及cross-SampEn,我们进一步发现cross-SampEn可更好地描述各个时间段之间的相互关系,从而提供一种选择性的并实用的方法来展示时间段之间的关系。结果进一步表明彼此关联较弱的市场依然存在,并且国与国之间受到危机的影响程度不同。

通过对辉绿岩的高温高压交代实验及理论计算,研究了洋中脊的热液交代过程。这一交代过程的存在可以从洋中脊的热液化学组成、挖掘到的变质玄武岩样品的化学、矿物学以及陆地上的蛇绿岩露头得到证实。所获结果表明,Mg、Ca、Na的固定反应分别发生在不同的交代条件下。Mg的固定反应发生在海底热液对流圈的下降翼,Ca、Na的固定主要和上升翼有关,其中Ca反应发生于深部,Na反应则位于上升翼近于海底的部位。热液中Ca的迁出,伴随着H^+的产生。减压过程大大地增进了这一反应。和其他含钙交代相相比,绿帘石的稳定性也因此而提高。在热液体系中,绿帘石和斜长石这两个固溶体制约着热液的化学成分和pH值。东太平洋隆起21°N黑烟囱中喷出的热液来自于385—400℃、300—400bar的反应带。只要弄清了盐度的影响、由传导冷却而造成的退变质过程以及混合过程,就可确定所有热液的反应带的温压条件。

An examination of available data reveals large trade misinvoicing between China and its trade partners. The analysis finds a net trade misinvoicing of US$287.6bn between 2000 and 2005, while the full magnitude of unrecorded trade is estimated at US$1.4tn. China needs to establish more effective management of its international trade flows. At the same time, the international community needs to provide more effective governance mechanisms to address trade misinvoicing.

we provide an integrative taxonomic analysis of the Lipinia vittigera species complex from mainland Southeast Asia. Based on examination of external morphology, color pattern, and 681 base pairs of the cytochrome oxidase subunit I (COI) mitochondrial gene, we demonstrate the presence of four morphologically distinct lineages of Lipinia in Vietnam, Cambodia, Thailand, and Malaysia, showing a sequence divergence ranging 15.5%–20.4%. All discovered lineages are discretely diagnosable from one another by a combination of scalation traits and color patterns. A review of the published distribution data and a re-examination of available type material revealed the following results:(1) distribution of L. vittigera (Boulenger, 1894) sensu stricto is restricted to Sundaland and the Thai-Malay Peninsula south of the Isthmus of Kra;(2) L. microcercus (Boettger, 1901) stat. nov. is elevated to full species rank;the species has a wide distribution from central and southern Vietnam across Cambodia to eastern Thailand;we regard Lygosoma vittigerum kronfanum Smith, 1922 and Leiolopisma pranensis Cochran, 1930 as its junior synonyms;(3) Lipinia trivittata sp. nov. occurs in hilly areas of southern Vietnam, Cambodia, and eastern Thailand;and (4) Lipinia vassilievi sp. nov. is currently known only from a narrow area along the Vietnamese-Cambodian border in the foothills of the central Annamite Mountain Range. we further provide an identification key for Lipinia occurring in mainland Southeast Asia.
