Mitochondrial membrane potential(MMP) plays many important roles in normal physiological function. Once, MMP generates unusual changes, mitochondrial functions would be severely affected, which further cause mitochondrial disorders. Hence, we design and synthesis a ratio fluorescent probe(TPP-SP) for the selective imaging of MMP at 563 and 663 nm. Moreover, TPP-SP possesses the good biocompatibility and the linear dependent with MMP, which inspired us to explore its feasibility to detect the real-time change of MMP during cells early apoptosis. Confocal microscopic imaging(Fig. I) showed that there only emitted fluorescence in green channel(520-620 nm) and very low fluorescence in red chennel(620-720 nm) when HePG2 cells don’t treated with CCCP. However, the intensity of green channel(520-620 nm) decreased while red chennel(620-720 nm) increased(Fig. Ⅱ) when He PG2 cells treated with CCCP by 5 min. Hence, the probe may have potential application varying from the morphology observation at subcellular level to accurate monitoring change of MMP in living cells.

施马伦贝格病(Schmallenbergdisease,SBD)是由施马伦贝格病毒(Schmallenbergvirus,SBV)引起的反刍动物虫媒传染病,目前对其尚无有效治疗手段,及时检测病原和抗体对其进行确诊,是其防控的重要举措。SBD诊断技术主要包括,病原学检测的病毒分离与鉴定、RT-PCR、实时荧光RT-RAA,血清学检测的病毒中和试验(VNT)、蚀斑减少中和试验(PRNT)、酶联免疫吸附试验(ELISA)、免疫层析试纸条。每种检测方法各有优势和不足,其中病毒分离与鉴定和VNT是经典的SBD确诊方法,但因其涉及病毒培养,操作严格,耗时长;RT-PCR和ELISA方法操作简单,是常用的SBV实验室检测方法;实时荧光RT-RAA和免疫层析试纸条检测反应时间短,适用于SBV的现场快速筛查。因此在实际应用时,可根据自身要求和目的,结合实际情况选择一种或多种检测方法进行SBD诊断。本文主要总结了近年来有关SBD的病原学和血清学诊断技术研究进展,以期为SBD监测和防控提供技术参考。

将风电功率预测信息纳入电力系统调度运行是解决风电波动的主要技术之一。受自然条件影响,风电功率预测的精度仍然较低。描述风电功率的不确定性并在机组组合中使用该信息,可提高机组组合决策的鲁棒性。文中分别采用点预测、区间预测和分位点预测描述风电功率的不确定性。在此基础上,分别建立了适合各种风电功率预测信息的机组组合模型。最后,采用IEEE-RTS96系统对所建机组组合模型进行测试,并在此基础上对各类预测信息在机组组合决策中的作用进行分析。测试结果证明了文中研究方法的有效性。

The poor interfacial contact is one of the biggest challenges that solid-state lithium batteries suffer *** the solid-state electrolyte surface energy by transforming the interface from lithiophobic to lithiophilic is effective to promote the interfacial contact, but electronic conductive interphases usually increase the risk of electron attack, thus leading to uncontrollable Li dendrite growth. Herein, we propose a self-assembled thermodynamic stable Li I interphase to simultaneously improve the interfacial contact between the garnet electrolyte Li_7La_(3)Zr_(2)O_(12)(LLZO) and Li anode, and prohibit the electron attack. The direct contact between LLZO and Li and the high temperature Li melting process was ascribed to Zr4+reduction, which facilitated Li dendrite formation and propagation. With the modification of the high lithiophilic I_(2) thin film, the area specific interfacial resistance of LLZO/Li was reduced from 1525 Ω/cm^(2) to 57 Ω/cm^(2). More importantly, LLZO was protected from being reduced due to the outstanding electronic insulativity of the Li I interphase, which leaded to a high critical current density of 1.2/7.0 m A/cm^(2) in the time/capacity-constant modes, respectively.

In this study, a total of 41 stations with both surface and benthic samples of phytoplankton and microorganisms were collected from December 14 th to December 25 th in Bohai Sea, 2013. According to the biological taxonomy, metagenomics and proteomics data, the compositions and diversities of phytoplankton and microorganism were determined. Furthermore, their relationships with the yellow sea warm current were investigated. The most wide spread species of phytoplankton in winter were Actinocyclus octonarius, Ceratium fusus, Coscinodiscus asteromphalus, Coscinodiscus oculusiridis, Coscinodiscus sp., Melosira sulcata, while the most abundant species were Actinocyclus octonarius, Chaetoceros sp., Coscinodiscus sp., Nitzschia pungens, Rhizosolenia alata f. Indica, Schroederella delicatula. Our results indicated that the yellow sea warm current had dramatic influences on the diversities of both phytoplankton and microorganisms mainly through temperature and salinity.

目的探讨恩诺沙星对鼠疫耶尔森菌(简称鼠疫菌)L型的诱导作用,以期了解更多鼠疫菌L型的形成条件和生物学特性。方法将鼠疫菌EV株分别接种于含0、0.5、5、10、50、100、500、1000 ng/mL恩诺沙星的赫氏培养基中培养。将含50 ng/mL恩诺沙星的培养物接种于不含恩诺沙星的赫氏培养基中进行返祖培养。观察各样品菌落形态,通过革兰染色和细胞壁染色观察细菌形态,透射电镜观察细胞壁状态。对鼠疫菌EV株和鼠疫菌L型进行16S rDNA鉴定,并进行同源性分析及构建系统发育树。结果赫氏培养基中含0.5 ng/mL恩诺沙星可引起鼠疫菌形态改变,由典型短杆菌变为长杆菌。恩诺沙星浓度为50 ng/mL时鼠疫菌细胞壁缺失,细菌无法正常分裂增殖而呈长杆状,盘绕成团,菌落呈油煎蛋样。恩诺沙星诱导鼠疫菌L型在正常赫氏培养基中可返祖,并表现为短小杆状的典型鼠疫菌形态。16S rDNA鉴定诱导菌与诱导前亲本EV株同源性为100%。结论恩诺沙星可诱导鼠疫菌形成L型。

针对激光测风雷达低空风切变识别率不高的现状,文章利用陕西榆林机场激光测风雷达的数据产品,开展数据质量控制,引入风切变强度因子构建滑动分析方法,使得低空风切变被有效识别。利用沙尘天气、持续大风天气和日变化天气下的风切变过程,结合航空器风切变报告、机场自动观测站气象报文,对下滑道上顶风和侧风廓线的风速进行逐点滑动判别与风切变强度识别,验证滑动分析方法的可用性与有效性。3个不同天气背景下的举例验证结果表明:通过逐点滑动分析,可判断下滑道上风切变强度因子最大值对应的高度位置与机组报告的风切变发生高度相吻合;风切变发生时,下滑道上侧风的时空变化明显大于顶风;在同一高度上,风速在短时间内存在较强的波动是造成风切变的原因之一。
