| 2 | Cell Death Mechanisms Induced by Cytotoxic Lymphocytes显示文摘One of the functions of the immune system is to recognize and destroy abnormal or infected cells to maintain homeostasis. This is accomplished by cytotoxic lymphocytes. Cytotoxicity is a highly organized multifactor process. Here,we reviewed the apoptosis pathways induced by the two main cytotoxic lymphocyte subsets,natural killer(NK) cells and CD8+ T cells. In base to recent experimental evidence,we reviewed NK receptors involved in recognition of target-cell,as well as lytic molecules such as perforin,granzymes-A and-B,and granulysin. In addition,we reviewed the Fas-FasL intercellular linkage mediated pathway,and briefly the cross-linking of tumor necrosis factor(TNF) and TNF receptor pathway. We discussed three models of possible molecular interaction between lytic molecules from effector cytotoxic cells and target-cell membrane to induction of apoptosis. | Chávez-Galán L Arenas-Del Angel MC Zenteno E Chávez R Lascurain R | 2009 | Cellular & Molecular Immunology2009，6，1： | 17 |
| 3 | Antenna-assisted picosecond control of nanoscale phase transition in vanadium dioxide显示文摘Nanoscale devices in which the interaction with light can be configured using external control signals hold great interest for next-generation optoelectronic circuits.Materials exhibiting a structural or electronic phase transition offer a large modulation contrast with multi-level optical switching and memory functionalities.In addition,plasmonic nanoantennas can provide an efficient enhancement mechanism for both the optically induced excitation and the readout of materials strategically positioned in their local environment.Here,we demonstrate picosecond all-optical switching of the local phase transition in plasmonic antenna-vanadium dioxide(VO_(2))hybrids,exploiting strong resonant field enhancement and selective optical pumping in plasmonic hotspots.Polarization-and wavelength-dependent pump–probe spectroscopy of multifrequency crossed antenna arrays shows that nanoscale optical switching in plasmonic hotspots does not affect neighboring antennas placed within 100 nm of the excited antennas.The antenna-assisted pumping mechanism is confirmed by numerical model calculations of the resonant,antenna-mediated local heating on a picosecond time scale.The hybrid,nanoscale excitation mechanism results in 20 times reduced switching energies and 5 times faster recovery times than a VO_(2) film without antennas,enabling fully reversible switching at over two million cycles per second and at local switching energies in the picojoule range.The hybrid solution of antennas and VO_(2) provides a conceptual framework to merge the field localization and phase-transition response,enabling precise,nanoscale optical memory functionalities. | Otto L Muskens Luca Bergamini Yudong Wang Jeffrey M Gaskell Nerea Zabala CH de Groot David W Sheel Javier Aizpurua | 2016 | Light(Science & Applications)2016，5，1： | 5 |

| 5 | RATIONAL GENERAL SOLUTIONS OF HIGHER ORDER ALGEBRAIC ODES显示文摘This paper generalizes the method of Ngo and Winkler(2010,2011)for finding rational general solutions of a first order non-autonomous algebraic ordinary differential equation(AODE)to the case of a higher order AODE,provided a proper parametrization of its solution hypersurface.The authors reduce the problem of finding the rational general solution of a higher order AODE to finding the rational general solution of an associated system.The rational general solutions of the original AODE and its associated system are in computable 1-1 correspondence.The authors give necessary and sufficient conditions for the associated system to have a rational solution based on proper reparametrization of invariant algebraic space curves.The authors also relate invariant space curves to first integrals and characterize rationally solvable systems by rational first integrals. | HUANG Yanli NG L X Chu WINKLER Franz | 2013 | Journal of Systems Science & Complexity2013，26，2： | 3 |
| 6 | 牛体内重组牛生长激素(rbST)的快速高灵敏度检测显示文摘重组牛生长激素(rbST)在一些国家和地区常被作为猪或牛的生长促进剂(用于乳牛可以增加牛奶产量),但在欧盟国家,有法规明确禁止生长激素的使用。重组牛生长激素本身是蛋白质,在生物基质中的浓度较低,且样品基质十分复杂,对其进行有效分析还存在一定难度,因而,长久以来其分析方法一直局限为酶联免疫检测法。 | Gaud Pinel Sandrine Roulet-Rochereau ylvain Chéreau Fabrice Monteau Bruno Le Bizec Paul Silcock Marie-Hélène Le Breton | 2010 | 食品安全导刊2010，，8： | 2 |
