1Direct reprogramming of human fibroblasts into dopaminergic neuron-like cells显示文摘外长的 dopaminergic 神经原(DA 神经原) 的移植是为治疗 Parkinson 的疾病(PD ) 的一条有希望的途径。然而,主要跌倒块是施主 DA 神经原的可靠来源的缺乏。这里,我们证明五 transcriptional 因素 Mash1, Ngn2, Sox2, Nurr1,和 Pitx3 的联合直接并且有效地装改编人成纤维细胞进 DA 像神经原的房间。为为 DA 神经原的各种各样的标记积极的染色的 reprogrammed 房间。他们也显示出典型 DA 举起和生产性质。而且,他们展出了 DA 神经原特定的 electrophysiological 侧面。最后,他们在一个老鼠 PD 模型提供了征兆的地势。因此,我们的直接 reprogrammed DA 像神经原的房间是为 PD 的房间代替治疗的有希望的来源。Xinjian Liu Fang Li Elizabeth A Stubblefield Barbara Blanchard Toni L Richards Gaynor A Larson Yujun He Qian Huang Aik-Choon Tan Dabing Zhang Timothy A Benke John R Sladek Nancy R Zahniser Chuan-Yuan Li 2012Cell Research2012,22,2:14
2Behavior modeling and verification of movement authority scenario of Chinese Train Control System using AADL显示文摘Train control systems like most digital controllers are, by definition, hybrid systems as they interact with or try to control some aspects of the physical world. Detailed behavior modeling with constraints specification and formal verification, required for reliability prediction, is a great challenge for hybrid system designers.Train control systems further intensify this challenge with extensive interaction between computing units and their physical environment and their mutual dependence on each other. In this paper, we investigate behavior modeling and formal verification of Chinese Train Control System Level 3(CTCS-3) using Architectural Analysis & Design Language(AADL) to cope with this challenge. AADL is an architecture description language for embedded systems and is based on model-based engineering paradigm. Along with structural modeling of embedded systems using the core language constructs, AADL also provides support for language extension through annex sublanguages. In system requirements specification document, the behavior of the CTCS-3 is specified as a set of basic operation scenarios that cooperate with each other to achieve safe and secure functionality of trains.Movement Authority(MA) scenario, explored in this paper, is considered as a basic and most crucial scenario to prevent trains from colliding with each other. The detailed discrete behavior of control system is modeled and verified using the Behavior Language for Embedded Systems with Software(BLESS) annex sublanguage of AADL, and the continuous behavior of train with the cyber–physical interaction(communication between train and control system) is modeled using the Hybrid annex sublanguage. The behavior of the MA scenario at system level is verified using the Hybrid Hoare Logic theorem prover. Behavior constraints are specified as assertions using first-order logic formulas augmented with a simple temporal operator.AHMAD Ehsan DONG YunWei LARSON Brian Lü JiDong TANG Tao ZHAN NaiJun 2015Science China(Information Sciences)2015,58,11:4
3小儿哮喘的现代概念显示文摘尽管对哮喘的进展有些了解,但本病在小儿中的发病率及病死率仍高。虽然涉及很多因素,但主要的因素是过量应用β兴奋药加之抗炎药使用不足引起病死率增高。对轻度哮喘亦存在气道炎症的论证及炎性刺激增加气道反应性的观察致使在疾病较早期应用抗炎药。但目前可得到的具有抗炎活性的药物不是对全部病人均有效。由小儿慢性严重哮喘(尽管适当应用皮质类固醇)提出的问题,提示我们现在的概念过于简单化。因此,卫生保健人员在对该病治疗时必须保持清醒的头脑。Larson G L 张雪青 1993国外医学(儿科学分册)1993,20,1:4
