N-Acylated homoserine lactone (AHL) lactonases are capable of degrading signal molecules involved in bacterial quorum sensing and therefore represent a new approach to control bacterial infection. Here a gene responsible for the AHL lactonase activity of Bacillus sp. strain AI96, 753 bp in length, was cloned and then expressed in Escherichia coli. The(More)
—Power-coupling models are inherently unable to describe certain mode coupling effects in multimode fiber (MMF) when using coherent sources at high bit rates, such as polarization dependence of the impulse response. We develop a field-coupling model for propagation in graded-index MMF, analogous to the principal-states model for polarization-mode dispersion(More)
The discovery of Rous sarcoma virus (RSV) led to the identification of cellular Src (c-Src), a non-receptor tyrosine kinase, which has since been implicated in the development of numerous human cancers. c-Src has been found to be highly activated in colon cancers, particularly in those metastatic to the liver. Studies of the mechanism of c-Src regulation(More)
We consider the problem of determining the capacity of an energy-harvesting transmitter with finite battery communicating over a discrete memoryless channel. When the battery is unlimited, or zero, the capacity has been determined, but it remains unknown for a finite non-zero battery. In this paper we assume that the harvested energy at each time, the total(More)
We applied event-related potentials (ERPs) to assess brain activities with inhibition of irrelevant conflict information processing during visual selective attention. Fifteen healthy subjects matched two sequentially presented color spots (S1 and S2) in a visual selective attention task. The two spots might be presented in a fixed position of either the(More)
Taurochenodeoxycholic acid (TCDCA) is one of the main bioactive substances of animals' bile acid. In this study, we aimed to investigate the anti-arthritic effects and potential mechanism of TCDCA on adjuvant arthritis (AA) in rats. Freund's complete adjuvant (FCA) was used to induce AA in rats. Paw swelling, index of thymus and spleen and body weight(More)
PURPOSE This study was designed to evaluate the therapeutic effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on patients with refractory partial epilepsy. METHODS Sixty-four patients with refractory focal epilepsy were screened and 60 patients were randomly divided into two groups by stimulation intensity: 90% (group 1) or 20%(More)
To study the role of the adiponectin (ADIPOQ) gene single-nucleotide polymorphism (SNP) in the susceptibility and prognosis for non-small cell lung cancer (NSCLC), we recruited 344 patients with NSCLC, of which 141 had undergone surgical resection and post-surgery follow up. For controls, there were 264 healthy volunteers for the control group, matched in(More)
Current models suggest that colon cancer initiation and progression are secondary to both the activation of oncogenes and the deletion of tumor suppressor genes. The role of each, however, is still poorly understood, particularly with regard to the induction of metastasis. We hypothesized that genetic differences exist between tumors that metastasize(More)
