Advances in the chip fabrication technology have begun to make manufacturing 3D chips a reality. For 3D designs to achieve their full potential, it is imperative to develop effective physical design strategies that handle the complexities and new objectives specific to 3D designs. We present two frameworks of placement and routing techniques, for 3D FPGA(More)
The polycomb group protein B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1) is dysregulated in various cancers, and its upregulation strongly correlates with an invasive phenotype and poor prognosis in patients with nasopharyngeal carcinomas. However, the underlying mechanism of Bmi-1-mediated invasiveness remains unknown. In the current study, we found(More)
We present a method for high-throughput cytological profiling by microscopy. Our system provides quantitative multidimensional measures of individual cell states over wide ranges of perturbations. We profile dose-dependent phenotypic effects of drugs in human cell culture with a titration-invariant similarity score (TISS). This method successfully(More)
Stable BHK cell lines inducibly expressing wild-type or dominant negative mutant forms of the rab7 GTPase were isolated and used to analyze the role of a rab7-regulated pathway in lysosome biogenesis. Expression of mutant rab7N125I protein induced a dramatic redistribution of cation-independent mannose 6-phosphate receptor (CI-MPR) from its normal(More)
BACKGROUND Higher fat mass may be an independent risk factor for osteoporosis and osteoporotic fractures. OBJECTIVE We aimed to determine the independent contribution of fat mass to osteoporosis and to estimate the risk of osteoporotic fractures in relation to body weight, lean mass, and other confounders. DESIGN This was a community-based,(More)
Regulation of membrane trafficking requires the concerted actions of rab proteins, their effectors and several phosphatidylinositol 3'-kinases. Rab7 is required for late endosomal transport and here we establish that the phosphatidylinositol 3'-kinase hVPS34 and its adaptor protein p150 are rab7 interacting partners. The hVPS34/p150 complex colocalized with(More)
The Wnt/β-catenin signalling pathway plays essential roles in embryonic development and adult tissue homeostasis, and deregulation of this pathway has been linked to cancer. Axin is a concentration-limiting component of the β-catenin destruction complex, and its stability is regulated by tankyrase. However, the molecular mechanism by which(More)
Nicotine is the major addictive substance in cigarettes, and genes involved in sensing nicotine are logical candidates for vulnerability to nicotine addiction. We studied six single-nucleotide polymorphisms (SNPs) in the CHRNA4 gene and four SNPs in the CHRNB2 gene with respect to nicotine dependence in a collection of 901 subjects (815 siblings and 86(More)
A phenotypic screen was used to search for drug-like molecules that can interfere with specific steps in membrane traffic. 2-(4-Fluorobenzoylamino)-benzoic acid methyl ester (Exo1), identified in this screen, induces a rapid collapse of the Golgi to the endoplasmic reticulum, thus acutely inhibiting the traffic emanating from the endoplasmic reticulum. Like(More)
The large size of modern FPGAs has caused researchers to consider deploying hierarchical techniques in their design. In this paper, we consider the floorplanning of FPGAs. We present a two-step approach for the floorplanning of modern FPGAs that we believe is cleaner and more versatile than recent floorplanners. The steps, based on resource-aware fixed(More)
