We address the problem of predicting new drug-target interactions from three inputs: known interactions, similarities over drugs and those over targets. This setting has been considered by many methods, which however have a common problem of allowing to have only one similarity matrix over drugs and that over targets. The key idea of our approach is to use(More)
PURPOSE To determine whether polymorphisms in the Toll-like receptor 4 (TLR4) gene are associated with primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG), and exfoliation glaucoma (XFG) in Japanese individuals. DESIGN Genetic association study. METHODS SETTING Multicenter study. STUDY POPULATION One hundred eighty-four unrelated(More)
Patulin is a mycotoxin produced by Penicillium species which often contaminates fruit and fruit-derived products. In this work the degradation of patulin by the yeast Rhodosporidium paludigenum was studied and the toxicity of the degradation product was determined. Patulin-degrading activity of R. paludigenum was inducible by patulin; it was located within(More)
The basic helix-loop-helix (bHLH) proteins play important regulatory roles in eukaryotic developmental processes including neurogenesis, myogenesis, hematopoiesis, sex determination, and gut development. Zebrafish is a good model organism for developmental biology. In this study, we identified 139 bHLH genes encoded in the zebrafish genome. Phylogenetic(More)
In human coronary arterioles (HCAs) from patients with coronary artery disease, flow-induced dilation is mediated by a unique mechanism involving the release of H(2)O(2) from the mitochondria of endothelial cells (ECs). How flow activates ECs to elicit the mitochondrial release of H(2)O(2) remains unclear. Here, we examined the role of the transient(More)
Prostate cancer risk-associated variants have been reported in populations of European descent, African-Americans and Japanese using genome-wide association studies (GWAS). To systematically investigate prostate cancer risk-associated variants in Chinese men, we performed the first GWAS in Han Chinese. In addition to confirming several associations reported(More)
Coleoids are part of the Cephalopoda class, which occupy an important position in most oceans both at an ecological level and at a commercial level. Nevertheless, some coleoid species are difficult to distinguish with traditional morphological identification in cases when specimens are heavily damaged during collection or when closely related taxa are(More)
DNA sequence data enable not only the inference of phylogenetic relationships but also provide an efficient method for species-level identifications under the terms DNA barcoding or DNA taxonomy. In this study, we have sequenced partial sequences of mitochondrial COI and 16S rRNA genes from 63 specimens of 8 species of Pectinidae to assess whether DNA(More)
BACKGROUND Arachidonic acid (AA) and/or its enzymatic metabolites are important lipid mediators contributing to endothelium-derived hyperpolarizing factor (EDHF)-mediated dilation in multiple vascular beds, including human coronary arterioles (HCAs). However, the mechanisms of action of these lipid mediators in endothelial cells (ECs) remain incompletely(More)
Transient receptor potential vanilloid type 4 (TRPV4) is an endothelial Ca(2+) entry channel contributing to endothelium-mediated dilation in conduit and resistance arteries. We investigated the role of TRPV4 in the regulation of blood pressure and endothelial function under hypertensive conditions. TRPV4-deficient (TRPV4(-/-)) and wild-type (WT) control(More)
