Fluorescent nanocrystals composed of semiconductor materials were first introduced for biological applications in the late 1990s. The focus of this review is to give a brief survey of biological applications of quantum dots (QDs) at the single QD sensitivity level. These are described as follows: 1) QD blinking and bleaching statistics, 2) the use of QDs in high speed single particle tracking with a special focus on how to design the biofunctional coatings of QDs which enable specific targeting to single proteins or lipids of interest, 3) a hybrid lipid-DNA analogue binding QDs which allows for tracking single lipids in lipid bilayers, 4) two-photon fluorescence correlation spectroscopy of QDs and 5) optical trapping and excitation of single QDs. In all of these applications, the focus is on the single particle sensitivity level of QDs. The high applicability of QDs in live cell imaging experiments held together with the prospects in localization microscopy and single molecule manipulation experiments gave QDs a promising future in single molecule research.

ACAT抑制对冠状动脉粥样硬化进展的影响

世界核心医学期刊文摘（心脏病学分册） 2006年第9期2卷 6-7页

作者： Nissen S.E. Tuzcu E.M. brewer H.B. 杜媛 Department of Cardiovascular Medicine Cleveland Clinic Foundation9500 Euclid Ave.ClevelandOH 44195United States.Dr

Background: The enzyme acyl-coenzyme A:cholesterol acyltransferase(ACAT) esterifies cholesterol in a variety of tissues. In some animal models, ACAT inhibitors have antiatherosclerotic effects. Methods: We performed intravascular ultrasonography in 408 patients with angiographically documented coronary disease. All patients received usual care for secondary prevention, including statins, if indicated. Patients were randomly assigned to receive the ACAT inhibitor pactimibe(100 mg per day) or matching placebo. Ultrasonography was repeated after 18 months to measure the progression of atherosclerosis. Results: The primary efficacy variable analyzing the progression of atherosclerosis-the change in percent atheroma volume-was similar in the pactimibe and placebo groups(0.69 percent and 0.59 percent, respectively; P=0.77). However, both secondary efficacy variables assessed by means of intravascular ultrasonography showed unfavorable effects of pactimibe treatment. As compared with baseline values, the normalized total atheroma volume showed significant regression in the placebo group(-5.6 mm3, P=0.001) but not in the pactimibe group(-1.3 mm3, P=0.39; P=0.03 for the comparison between groups). The atheroma volume in the most diseased 10-mm subsegment regressed by 3.2 mm3 in the placebo group, as compared with a decrease of 1.3 mm3 in the pactimibe group(P=0.01). The combined incidence of adverse cardiovascular outcomes was similar in the two groups(P=0.53). Conclusions: For patients with coronary disease, treatment with an ACAT inhibitor did not improve the primary efficacy variable(percent atheroma volume) and adversely affected two major secondary efficacy measures assessed by intravascular ultrasonography. ACAT inhibition is not an effective strategy for limiting atherosclerosis and may promote atherogenesis.(*** number, NCT 00268515).

对十六个城市污泥样品中的挥发性亚硝胺类,尤其是二甲基亚硝胺(DMN)和二乙基亚硝胺(DEN)进行了分析。200克样品在索氏提取器中用二氯甲烷提取3小时。将提取物浓缩并者悬浮于蒸馏水中,以供气液色谱、薄层色谱和比色分析之用。在11个样品中,用比色法检出亚硝胺。用两种色谱法分析,在6个样品中检出了DMN,在3个样品中检出了DEN。在另加标准物的2个样品中,用薄层色谱法分析仅检出了DMN。根据已知的施用于农业土壤的污泥样品中,DMN的平均含量为0.272微克/克(按污泥湿重计算)。研究结果表明:由于直接施用污泥于土壤中,每年每平方米土壤要混合进59.8至1365微克的亚硝胺。根据计算,平均施用率为每年每平方米土壤530.4微克的亚硝胺。
