RDF Curator: A Novel Workflow that Generates Semantic Graph from Literature for Curation Using Text Mining

There exist few databases that enable cross-reference among various research fields related to bioenergy. Cross-reference is highly desired among bioinformatics databases related to environment, energy, and agriculture for better mutual cooperation. By uniting Semantic Graph, we can economically construct a distributed database, regardless of the size of research laboratories and research endeavors.

Our purpose is to design and develop a workflow based on RDF (Resource Description Framework) that generates Semantic Graph for a set of technical terms extracted from documents of various formats, such as PDF, HTML, and plain text. Our attempt is to generate Semantics Graph as a result of text mining including morphological analysis and syntax analysis.

We have developed a prototype of workflow program named "RDF Curator". By using this system, various types of documents can be automatically converted into RDF. "RDF Curator" is composed of general tools and libraries so that no special environment is needed. Hence, “RDF Curator” can be used on many platforms, such as MacOSX, Linux, and Windows (Cygwin). We expect that our system can assist human curators in constructing Semantic Graph. Although fast and high throughput, the accuracy of the present version of "RDF Curator" is lower than that of human curators. As a future task, we have to improve the accuracy of the workflow. In addition, we also plan to apply our system to analysis of network similarity

Construction of next generation mobile video on demand delivery system using broadcast and communication integration environments

GCCE2015 : IEEE 4th Global Conference on Consumer Electronics , Oct 27-30, 2015 , Osaka, JapanWatching high quality videos anytime, anywhere is expected because mobile devices become popular. However, if mobile devices try to watch a video at the same time via a wireless network, the concentrated loads to delivery server cause a delay and a stop of playing videos on client devices. Therefore, in this paper, we realize a mobile video on demand delivery system that mobile devices can watch high quality videos continuously by integrated methods of broadcast and communication. We delvelop the prototype system and have practical experiments to evaluate the proposed system

Regulation of Chromatin Structure During Neural Development

The regulation of genome architecture is a key determinant of gene transcription patterns and neural development. Advances in methodologies based on chromatin conformation capture (3C) have shed light on the genome-wide organization of chromatin in developmental processes. Here, we review recent discoveries regarding the regulation of three-dimensional (3D) chromatin conformation, including promoter–enhancer looping, and the dynamics of large chromatin domains such as topologically associated domains (TADs) and A/B compartments. We conclude with perspectives on how these conformational changes govern neural development and may go awry in disease states

Comprehensive analysis of resistance-nodulation-cell division superfamily (RND) efflux pumps from Serratia marcescens, Db10

We investigated the role of the resistance-nodulation-cell division superfamily (RND) efflux system on intrinsic multidrug resistance in Serratia marcescens. We identified eight putative RND efflux system genes in the S. marcescens Db10 genome that included the previously characterized systems, sdeXY, sdeAB, and sdeCDE. Six out of the eight genes conferred multidrug resistance on KAM32, a drug hypersensitive strain of Escherichia coil. Five out of the eight genes conferred resistance to benzalkonium, suggesting the importance of RND efflux systems in biocide resistance in S. marcescens. The energy-dependent efflux activities of five of the pumps were examined using a rhodamine 6G efflux assay. When expressed in the toiC-deficient strain of E. coil, KAM43, none of the genes conferred resistance on E. coil. When hasF, encoding the S. marcescens ToIC ortholog, was expressed in KAM43, all of the genes conferred resistance on E. coil, suggesting that HasF is a major outer membrane protein that is used by all RND efflux systems in this organism. We constructed a sdeXY deletion mutant from a derivative strain of the clinically isolated multidrug-resistant S. marcescens strain and found that the sdeXY deletion mutant was sensitive to a broad spectrum of antimicrobial agents

Early effect of oral administration of omeprazole with mosapride as compared with those of omeprazole alone on the intragastric pH

<p>Abstract</p> <p>Background</p> <p>The ideal medication for acid-related diseases should have a rapid onset of action to promote hemostasis and cause efficient resolution of symptoms. The aim of our study was to comparatively investigate the inhibitory effect on gastric acid secretion of a single oral administration of omeprazole plus mosapride with that of omeprazole alone.</p> <p>Methods</p> <p>Ten Helicobacter pylori-negative male subjects participated in this randomized, two-way crossover study. Intragastric pH was monitored continuously for 6 hours after a single oral administration of omeprazole 20 mg or that of omeprazole 20 mg plus mosapride 5 mg (the omeprazole being administered one hour after the mosapride). Each administration was separated by a 7-days washout period.</p> <p>Results</p> <p>The average pH during the 6-hour period after administration of omeprazole 20 mg plus mosapride 5 mg was higher than that after administration of omeprazole 20 mg alone (median: 3.22 versus 4.21, respectively; <it>p </it>= 0.0247).</p> <p>Conclusions</p> <p>In H. pylori -negative healthy male subjects, an oral dose of omeprazole 20 mg plus mosapride 5 mg increased the intragastric pH more rapidly than omeprazole 20 mg alone.</p

Isolation of genetically manipulated neural progenitors and immature neurons from embryonic mouse neocortex by FACS

Summary: The embryonic mammalian neocortex includes neural progenitors and neurons at various stages of differentiation. The regulatory mechanisms underlying multiple aspects of neocortical development—including cell division, neuronal fate commitment, neuronal migration, and neuronal differentiation—have been explored using in utero electroporation and virus infection. Here, we describe a protocol for investigation of the effects of genetic manipulation on neural development through direct isolation of neural progenitors and neurons from the mouse embryonic neocortex by fluorescence-activated cell sorting.For complete details on the use and execution of this protocol, please refer to Tsuboi et al. (2018) and Sakai et al. (2019)
