Ellagic acid has been demonstrated to inhibit the growth of several types of cancer cells. However, whether it sensitizes human colorectal carcinoma cells to 5-fluorouracil, has not yet been investigated. Colorectal carcinoma HT-29, Colo 320DM, SW480 and LoVo cells were treated with ellagic acid (2.5-25 μg/ml) and 5-fluorouracil (5-25 μM) alone and in(More)
This paper proposes a systematic method of system identification and control of a proton exchange membrane (PEM) fuel cell. This fuel cell can e used for low-power communication devices involving complex electrochemical reactions of nonlinear and time-varying dynamic properties. rom a system point of view, the dynamic model of PEM fuel cell is reduced to a(More)
This paper develops a multivariable robust controller for a proton exchange membrane fuel cell (PEMFC) system. To give a perspective of the system, a PEMFC can be simplified as a two-input-two-output model, where the inputs are air and hydrogen flow rates, while the outputs are cell voltage and current. By fixing the output resistance, we aim to control the(More)
Sex-determining region Y (SRY)-box protein 2 (SOX2) plays a critical role in stem cell maintenance and carcinogenesis. In addition to its function as a minor-groove DNA binding transcription factor, our previous study showed that SOX2 also acts as a RNA binding protein. In current study, we first showed that SOX2 displayed high affinity toward the mRNA(More)
We will describe a dynamic federated autonomic networking system1 for the testing of netcentric systems across organizations. Using a suite of policy-based management software tools, our system can provide netcentric missions with self-configuring, self-debugging, self-healing, and self-protecting capabilities across end-to-end coalition networks. The(More)
In order to facilitate a robust object oriented definition of policy exchange interfaces across semi-autonomous domains within an enterprise, a protocol neutral approach to describing the information exchanged is followed. This protocol neutral approach makes use of the Unified Modeling Language (UML) to describe information classes and their properties as(More)
Graphene is a highly promising candidate to replace oxide-based conducting materials for fabrication of transparent electrodes used in flexible displays and electronic devices. However, so far an appropriate method is still not found to provide high-quality, low-cost graphene in a large quantity. To overcome this issue, we demonstrate that massive graphene(More)
BACKGROUND Hypoxia has been shown to facilitate tumor progression. Hypoxia-regulated microRNA-210 (miR-210) may play an important role in carcinogenesis and tumor progression. In this study, we evaluated the clinical significance of miR-210 expression in upper tract urothelial carcinoma (UTUC). METHODS Eighty-three UTUC patients participated in this(More)
