The translational control of oncoprotein expression is implicated in many cancers. Here we report an eIF4A RNA helicase-dependent mechanism of translational control that contributes to oncogenesis and underlies the anticancer effects of silvestrol and related compounds. For example, eIF4A promotes T-cell acute lymphoblastic leukaemia development in vivo and(More)
The authors conducted a case-control study of Parkinson's disease patients with and without visual hallucinations to investigate associations of the polymorphisms of the dopamine receptors D2 32806 C>T (Taq1A), D3 Ser9Gly and Msp1, D5 978T>C and dopamine transporter 3'-UTR 40 bp VNTR with visual hallucinations in Parkinson's disease. No significant(More)
Infantile neuroaxonal dystrophy (INAD) is a progressive, autosomal recessive neurodegenerative disease characterized by axonal dystrophy, abnormal iron deposition and cerebellar atrophy. This disease was recently mapped to PLA2G6, which encodes group VI Ca(2+)-independent phospholipase A(2) (iPLA(2) or iPLA(2)β). Here we show that genetic ablation of PLA2G6(More)
Mitochondria-mediated production of reactive oxygen species (ROS) plays a key role in apoptosis. Mitochondrial phospholipid cardiolipin molecules are likely the main target of ROS because they are particularly rich in polyunsaturated fatty acids. They are also located in the inner mitochondrial membrane near the ROS-producing sites. Under physiological(More)

The model driven architecture (MDA) has been widely used as a paradigm in software development. This paper presents an overview on the current research in the model driven architecture. We analyze the key concepts of the MDA by illustrative examples, explore the existing approaches and tools that support model transformation - the essential part of the MDA,(More)
Discovering program behaviors and functionalities can ease program comprehension and verification. Existing program analysis approaches have used text mining algorithms to infer behavior patterns or formal models from program execution. When one tries to identify the hierarchical composition of a program behavior at different abstraction levels, textual(More)
This paper presents a graph transformation based approach to design pattern evolution. An evolution of a design pattern includes modifications of pattern elements, such as classes, attributes, operations and relationships between classes. Compared with other techniques, graphical notation, as a natural and intuitive way in software modeling, is suitable to(More)
This paper proposes a novel kind of multi-operator multi-robot(MOMR) teleoperation systems - the competitive teleoperation system. Compared with the conventional collaborated MOMR teleoperation system, features and properties of the competitive teleoperation system are presented. Futhermore, major concerns of research and development for this kind of(More)
This paper introduces a new application of a virtual repulsive force feedback (VRFF) in telegame, a competitive multi-robot teleoperation system. This system allows multiple users to play the game competitively over the Internet. To improve the teleoperator's situation awareness and enhance the control dexterity, many virtual reality approaches are used in(More)
