    CEC (capillary electrochromatography, CEC) is the continuous development of capillary electrophoresis and high performance liquid chromatography increasingly sophisticated theories developed on the basis of a double separation performance between the two analytical methods of separation [64,65] . It filled in a capillary liquid chromatography stationary phase or in the wall bonded stationary phase, high-voltage imposed at both ends to electroosmotic flow-driven mobile phase through column chromatography, solute according to their fixed and mobile phase between the phase distribution as well as their different electrophoretic mobility and can be separated. CEC in a plug flow pattern instead of the electroosmotic flow has a parabolic flow pattern of the pressure flow, which has a capillary zone electrophoresis (CZE) high column efficiency. CEC liquid chromatography using the stationary phase and mobile phase, which also has a high selectivity of high-performance liquid chromatography. Therefore, CEC has been since its birth in Analytical Chemistry is a hot area of research topics and application areas have gradually [66,67]. CEC is the core component of capillary electrochromatography column. Stationary phases based on the existence of different forms of capillary Power was divided into open tubular column, packed column and monolithic column. In the operation of the Joule heating effect, interface effect plug and fill the bubble effect of limiting the CEC (packed-column CEC, PCCEC) the development and application of column [68,69]. Monolithic column there is swelling, heat deformation, insufficient and poor mechanical properties, and it is difficult to obtain a very uniform pore size distribution for bed, so when the separation of small molecule compounds difficult to obtain higher column efficiency [2]. Preparation of open tubular column and run the process as simple and easy to control, high column efficiency and OTCEC the electroosmotic flow velocity ratio PCCEC large 60% [70] and therefore are more suitable for rapid analysis. However, its biggest drawback is that compared to small, low-capacity columns. Preparation of open tubular column is therefore the key is to increase the surface area, improve the capacity compared to column. This section, we will be prepared in the previous section octadecyl modified nano-silica coated capillary column used OTCEC the field, and hopes that the nano-particle liquid phase deposition to increase compared to the stationary phase to enhance the capacity of column. Subsequently, we looked at the column of the electroosmotic flow behavior, and the performance of electrochromatography is evaluated. 看看行吗?

Internationalised Normal Ratio(INR) elevations and/or bleeding events have been reported in some patients taking warfarin(see Pharmacokinetic Properties' section). patients taking warfarin should be monitored regularly for changes in prothrombin time or INR. patients shouldbe advised to seek medical advice promptly in the event of developing any eye symptoms or severe or persistent diarrhoea , nausea vomiting or anorexia(see Pharmacokinetic Properties' section). These symptoms should be managed as clinically indicated. Randomised controlled trials have demonstrated that Iressa combined with doublet , platinum-based cytotoxic chemotherapy in advanced NSCLC provides no added benefit over ther cytototxic in patientswho have previously received treatment with cytotoxic chemotherapy. In a phase I/II trial of IRESSA and radiation in paediatric patients, newly diagnosed with brain stem glioma or incompletely resected supratentorialmalignant glioma, 4 cases(1fatal) of CNS haemorrhages have been reported from trialwith IRESSA alone. There is no evidence to suggest any increased risk of cerebral haemorrhage in adult patients with NSCLC receiving IRESSA. Phase IIclinical trial data, where IRESSA and vinorelbine have been used concomitantly, indicate that Iressa may exacebate the neutropenic effctof vinorbine. Interaction with other medicinal products and other forms of interaction In vitro studies with human hepatic microsomes have shown that the metabolism of gefitinib is predomiantly via the CYP3A4 isoform of the hepatic cytochromeP-450 system. Gefitinib may be sxpected to interact with otehr drgs that induce, inhibit or are metabolised by this system. Gefitinib showed littl enzyme induction effect in animal studies and in vitro sutdies have shown that gefitinib has limited potentialto inhibit CYP2D6. The clinically or potentially significantclinical drug interactions between gefitinib and the following drugs/ durg classes are described below. Other Drugs that effect gefitinib Demonstrated interactions Drugs that inhaibit CYP3A4 co-administraion with itraconazole(a CYP3A4)resuulted in an 80% increase in the mean AUC of gefitinibin healthy volunteers. This increase may bbe clinically relevant since adverse experiences are related to dose and exposure. Although interaction studies with other CYP3A4 inhibitors have not been performed it is expected that drugs such as ketoconaxole, clotrimazole, ritonovir would also inhibit gefitinib metabolism. Drugs that Increase gastric pH In a trial in healthy volunteers co-adminstrationof drugs that cause significant sustined elevations in gastric pH>=5, resulted in a reduced mean gefitinib AUC by 47%. This may reduce efficacy Rifampicin Co-administration with rifa mpicin(a known potent CYP3A4 inducer) in healthy volunteers reduced meangefitinib AUC by 83% of that without rifampicin.

Bimetallic dendrimer-encapsulated nanoparticles(DENs)are important materials,because they have demonstrated improvement in performance compared to the monometallic DENs in many systems when they are used as catalysts.This tutorial review focuses on the recent research advances in bimetallic DENs with respect to their synthesis,characterization,and applications as catalysts.Bimetallic DENs can be made mainly via three routes:co-complexation,sequential loading,and partial displacement.The research in bimetallic DENs has been significantly promoted by the advancement of characterization instruments.The performances of bimetallic DENs as homogeneous and heterogeneous catalysts in organic synthesis have been compared with both monometallic DENs and their physical mixtures.It is concluded that the synergistic electronic effect in bimetallic nanoparticles enhances their catalytic activities. 能翻译多少都可以的 展开

D ,L252单取代海因是工业生产 D2氨基酸的重要前体[1~3 ]。海因酶具有底物特异性 ,D2海因酶(EC 3151212)可转化外消旋的D ,L252单取代海因中的D型消旋体成为D2N2氨甲酰氨基酸 ,剩余的L252单取代海因由于完全不被 D2海因酶所作用 ,如图 1所示 ,先进行消旋 ,从而使得 D ,L2海因完全转化为光学纯的 D2N2氨甲酰氨基酸 ,并进一步被转化为D2氨基酸。因此 ,52单取代海因的自发消旋成为L2或D2N2氨甲酰氨基酸生产中的一个重要的步骤。若海因的自发消旋速率远低于海因水解酶的水解速率 ,则海因的消旋将成为D2N2氨甲酰氨基酸生产中的一个限速步骤。目前关于 52单取代海因的消旋的文献非常少 ,海因消旋的细节问题也没有被完全揭示。 1 材料与方法 111 实验材料 L2丙氨酸(国家生化工程ZX) 、 L2苯丙氨酸(国家生化工程ZX) 、氰酸钠(江都化工厂) ,其他试剂为国产分析纯试剂。 112 实验方法 11211 52取代海因衍生物的制备 采用Henze2Speer法[4~5 ]进行52取代海因衍生物的制备: 反应温度为60~80 ℃。反应6 h后 ,加入盐酸酸化 ,继续加热 8 h ,冷却后过滤得到的固体用酒精和水的混合溶液重结晶 ,得到无色晶状目的产物。因使用的氨基酸不同 ,反应条件略有变化 ,产率一般为40 %~80 % ,所得的52取代海因具有和底物氨基酸相同的旋光方向。 11212 海因衍生物的消旋 a.精确称量41000 g L252甲基海因 ,溶解于蒸馏水中 ,定容至250 mL ,测定其旋光度 ,并以此值为未消旋化的起始数据。 b.用 6 mol/ L 的 NaOH溶液调整海因溶液 pH值达810 ,90 ℃水浴2 h ,于旋光仪上测定其旋光度。 c.同 b ,依次调节溶液pH值为710、 810、 910 ,分别测定其旋光度。 d.同 b ,依次于50 ℃水浴中及室温下恒温2 h ,分别测定其旋光度 ,并与起始数据对比 ,计算消旋比 r ( %) :r =αt/α0 ,其中αt 为 t 时间溶液的旋光度 ,α0为溶液初始旋光度。 11213 海因的碱解 精确称量41000 g L252甲基海因 ,溶解于蒸馏水中 ,定容至 250 mL ,用 NaOH溶液和盐酸分别调至pH = 2、 8、 12 , 90 ℃水浴反应4 h ,中间取样测定其N2氨甲酰丙氨酸浓度。 11214 海因的转化 采用012 %的海因溶液 ,按 w (底物)∶ w (菌泥)= 1∶ 5的比例 ,于pH 915 ,温度40 ℃下进行转化。 取样:取样10 mL ,加入 5 mL 三停止反应 ,摇匀 ,放冰箱待测。 3 结 论 311 海因的消旋遵循本文所提出的碳负离子理论 ,其消旋过程为一级反应动力学过程。由海因消旋的半衰期可看出提高温度和pH对海因的消旋均有利 ,但pH过高的情况下海因则会发生碱解反应从而造成损失。 312 本文采用的海因转化酶系中所含为 D2海因酶 ,对D2海因的转化活性非常高 ,由此可见 ,如若采用的转化体系中没有消旋酶的存在 ,则海因的消旋成为海因酶转化生产光学活性氨基酸的一个限速步骤。 展开
