Nanoparticles have enormous potential for bioimaging and biolabeling applications, in which conventional organically based fluorescent labels degrade and fail to provide long-term tracking. Thus, the development of approaches to make fluorescent probes water soluble and label cells efficient is desirable for most biological applications. Here, we report on the fabrication and charac- terization of self-assembled nanodots （SANDs） from 3-aminopropyltriethoxysilane （APTES） as a probe for protein labeling. We show that fluorescent SAND probes exhibit both bright photoluminescence and biocompatibility in an aqueous environment. Selective in vitro imaging using protein and carbohydrate labeling of hepatoma cell lines are demonstrated using biocompatible SANDs conjugated with avidin and galactose, respectively. Cytotoxicity tests show that conjugated SAND particles have negligible effects on cell proliferation. Unlike other synthetic systems that require multistep treatments to achieve robust surface functionalization and to develop flexible bioconjugation strategies, our results demonstrate the versatility of this one-step SAND fabrication method for creating multicolor fluorescent probes with the tailored functionalities, effident emission, as well as excellent biocompatibility, required for broad biological use.

Based on the remote sensing (RS) and geographic information system (GIS) analysis of the Landsat multispectral scanner (MSS) and thematic mapper (TM) satellite images of 1983, 1993, and 2005, the present research examined the effectiveness of the urban construction boundaries (UCBs) in containing urban growth within the 6th Ring Road of Beijing Municipality. Three indicators on boundary control were proposed, through which the effectiveness of boundary containment, land inventory sufficiency and illegal adjacent development to the UCBs were explored. The results suggested that, first, the UCBs were limited in effectiveness in containing urban growth; second, the area encompassed by the UCBs might not be designed large enough to accommodate new development. The frustration of the urban growth control through the UCBs mainly resulted from the lack of a transparent system for urban land use planning and control to provide sufficient information, the limitation of the traditional land use prediction method to consider contingencies, and the absence of a mechanism to monitor and adjust the UCBs to respond just in time to urban change.

为满足消费者对营养健康、风味多样的方便食品较高的需求,以高湿挤压大豆蛋白肉为原料开发了传统菜肴宫保鸡丁的仿真预制菜(The prepared dish kung Pao Chicken with soy protein artificial meat,SPAM-KPC),并比较了不同贮藏温度(4、25和37℃)下SPAM-KPC贮藏品质的变化。以菌落总数为影响产品货架期的关键品质因子,建立了SPAM-KPC的货架期预测模型。结果发现:三种温度下贮藏15 d的SPAM-KPC样品菌落总数从0.67 lg(CFU/g)分别增长至2.73、3.37、4.33 lg(CFU/g);pH(从6.22分别下降至5.98、5.87和5.69)和感官得分(从25.12分别下降至22.67、19.52和16.84)逐渐降低;SPAM-KPC样品颜色逐渐加深,硬度和弹性降低。三种贮藏温度下SPAM-KPC产品的货架期分别为28、20和17 d。表明4℃低温贮藏是SPAM-KPC产品的最佳贮藏温度。本研究为植物基蛋白肉在预制菜加工领域的应用提供了理论参考。

AIM： To examine the sensitivity and accuracy of real-time polymerase chain reaction （PCR） for the quantification of hepatitis B virus （HBV） DNA in semen. METHODS： Hepatitis B viral DNA was isolated from HBV carriers＇ semen and sera using phenol extraction method and QIAamp DNA blood mini kit （Qiagen, Germany）. HBV DNA was detected by conventional PCR and quantified by TaqMan technology-based real-time PCR （quantitative polymerase chain reaction （qPCR））. The detection threshold was 200 copies of HBV DNA for conventional PCR and 10 copies of HBV DNA for real time PCR per reaction. RESULTS： Both methods of phenol extraction and QIAamp DNA blood mini kit were suitable for isolating HBV DNA from semen. The value of the detection thresholds was 500 copies of HBV DNA per mL in the semen. The viral loads were 7.5×10^7 and 1.67×10^7 copies of HBV DNA per mL in two HBV infected patients＇ sera, while 2.14×10^5 and 3.02×10^5 copies of HBV DNA per mL in the semen. CONCLUSION： Real-time PCR is a more sensitive and accurate method to detect and quantify HBV DNA in the semen.
