2Super-resolution dipole orientation mapping via polarization demodulation显示文摘Fluorescence polarization microscopy(FPM)aims to detect the dipole orientation of fluorophores and to resolve structural information for labeled organelles via wide-field or confocal microscopy.Conventional FPM often suffers from the presence of a large number of molecules within the diffraction-limited volume,with averaged fluorescence polarization collected from a group of dipoles with different orientations.Here,we apply sparse deconvolution and least-squares estimation to fluorescence polarization modulation data and demonstrate a super-resolution dipole orientation mapping(SDOM)method that resolves the effective dipole orientation from a much smaller number of fluorescent molecules within a sub-diffraction focal area.We further apply this method to resolve structural details in both fixed and live cells.For the first time,we show that different borders of a dendritic spine neck exhibit a heterogeneous distribution of dipole orientation.Furthermore,we illustrate that the dipole is always perpendicular to the direction of actin filaments in mammalian kidney cells and radially distributed in the hourglass structure of the septin protein under specific labelling.The accuracy of the dipole orientation can be further mapped using the orientation uniform factor,which shows the superiority of SDOM compared with its wide-field counterpart as the number of molecules is decreased within the smaller focal area.Using the inherent feature of the orientation dipole,the SDOM technique,with its fast imaging speed(at sub-second scale),can be applied to a broad range of fluorescently labeled biological systems to simultaneously resolve the valuable dipole orientation information with super-resolution imaging.Karl Zhanghao Long Chen Xu-San Yang Miao-Yan Wang Zhen-Li Jing Hong-Bin Han Michael Q Zhang Dayong Jin Jun-Tao Gao Peng Xi 2016Light(Science & Applications)2016,5,1:11
3曹雪涛院士科研团队论文荣膺中国百篇最具影响国际学术论文--长链非编码RNA1nc-DC通过STAT3调控人DC的分化和功能显示文摘树突状细胞(DC)是免疫系统中重要的抗原提呈细胞,其成熟和功能状态决定着免疫应答的走向和强度。哺乳动物基因组能够转录产生大量的长链非编码RNA(long noncoding RNA,IncRNA),其在免疫系统中的功能还知之甚少。 曹雪涛院十科研团队王品副教授课题组采用了转录组芯片二代测序高通量筛选方法、RNA-pulldown、ChIP-seq等技术展开了对IncRNA在DC分化和功能中作用的研究,发现并鉴定了特异性高表达于DC的1ncRNA,命名为1nc-DC,其可通过抑制STAT3去磷酸化,从而促进DC分化和功能。该研究成果发表于Science杂志[2014,344(6181):310-313],并于2015年12月被评为“中国百篇最具影响国际学术论文”。wang p xue y han y lin l wu c xu s jiang z xu j liu q cao x 2016中国肿瘤生物治疗杂志2016,23,1:10
4Expression analysis of a-smooth muscle actin and tenascin-C in the periodontal ligament under orthodontic loading or in vitro culture显示文摘α-smooth muscle actin(α-SMA) and tenascin-C are stress-induced phenotypic features of myofibroblasts. The expression levels of these two proteins closely correlate with the extracellular mechanical microenvironment. We investigated how the expression of α-SMA and tenascin-C was altered in the periodontal ligament(PDL) under orthodontic loading to indirectly reveal the intrinsic mechanical microenvironment in the PDL. In this study, we demonstrated the synergistic effects of transforming growth factor-β1(TGF-β1) and mechanical tensile or compressive stress on myofibroblast differentiation from human periodontal ligament cells(h PDLCs). The h PDLCs under higher tensile or compressive stress significantly increased their levels of α-SMA and tenascin-C compared with those under lower tensile or compressive stress. A similar trend was observed in the tension and compression areas of the PDL under continuous light or heavy orthodontic load in rats. During the time-course analysis of expression, we observed that an increase in α-SMA levels was matched by an increase in tenascin-C levels in the PDL under orthodontic load in vivo. The time-dependent variation of α-SMA and tenascin-C expression in the PDL may indicate the time-dependent variation of intrinsic stress under constant extrinsic loading.Hui Xu Ding Bai L-Bruno Ruest Jian Q Feng Yong-Wen Guo Ye Tian Yan Jing Yao He Xiang-Long Han 2015International Journal of Oral Science2015,7,4:5
5在体背根神经节钙成像方法解析内脏痛及牵涉痛的新机制显示文摘内脏痛是指来自机体内在器官病理改变或功能异常引起的疼痛,常与多种内脏疾病相关,如急慢性肠炎等。内脏痛往往伴有躯体一定部位的牵涉痛。到目前为止,内脏痛及其牵涉痛的机制仍不清楚。该研究采用在体背根神经节钙成像方法(in vivo DRG calcium imaging),大视野实时动态观察和研究内脏痛及牵涉痛的背根节(dorsal root ganglion,DRG)神经元相关机制。刘风雨(译) Gao XY Han S Huang Q 2021中国疼痛医学杂志2021,27,10:5

14卫星专用传感器微波成像仪/探测仪(SSMIS)观测资料在天气和气候研究中的应用(英文)显示文摘2003年10月18日,美国国防气象卫星计划成功发射搭载了专用传感器微波成像仪/探测仪的F-16卫星。然而由于天线自身热辐射和校准暖黑体的不稳定,第一个专用传感器微波成像仪/探测仪出现了一些重要的异常观测。美国海军实验室与美国国家海洋和大气管理局(NOAA)分别开发了两种算法来订正这些异常值。剔除了定标异常值后,专用传感器微波成像仪/探测仪资料目前在探空数据产品反演和资料同化中发挥了更加显著的作用。NOAA利用专用传感器微波成像仪已有算法生成了专用传感器微波成像仪/探测仪成像仪产品。此外,一些新开发的算法可以从专用传感器微波成像仪/探测仪资料中提取出云和降水的信息。在云冰云水的反演算法中,亮温是与云冰云水路径和粒子的平均直径相关的。利用一维变分反演系统,同时反演出了多数大气和地表条件下的大气温度、湿度以及水凝物的垂直廓线。在各种天气形势下,由专用传感器微波成像仪/探测仪资料反演得到的温度和湿度廓线的均方根误差通常分别小于2K和15%。为了同化专用传感器微波成像仪/探测仪资料,还发展了新的质量控制和偏差订正方法。在NOAA的全球预报系统中同化了专用传感器微波成像仪/探测仪资料后,对提高全球中期数值预报水平产生了中性和较小的正效果。Weng F Zou X Yan B Han Y Liu Q 2011气象科技进展2011,1,1:2
