In the current study, a nutrigenomics approach was utilized to evaluate the in vivo function of “Kikuimo Extract” (KE) in ovariectomized cynomolgus macaque, a post-menopausal non-human primate model. KE was administered orally before feeding, for 3 months for the following examinations: 1) the effect of KE on intestinal microbes was examined by quantitative analyses of the intestinal bacteria using real-time PCR with DNA extracted from monkey feces;2) the effect of KE on gene expression was investigated by real-time RT-PCR using RNA extracted from both the liver and adipose tissue of the monkeys. KE administration modulated menopause-mediated altered microbes to increase Lactobacilli, Veillonella, and Bacteroides in all monkeys. KE administration regulated the altered expression of functional genes, SCAP, LDLR, and LXRA (lipid metabolism);GLUT-4 (glucose transport);CYP1A1 and CYP1A2 (drug metabolism);and CYP-17-2 and CYP-19-2 (E2 synthesis) in the menopausal monkeys. In menopausal monkeys, KE showed potent prebiotic effect on beneficial microflora and regulating effect on altered expression of functional genes associated with metabolism and E2 production. Thus, KE appears to be a practical functional food that alleviates the altered conditions of intestinal microbes and gene expression in the liver and adipose tissue in a menopausal state.展开更多

The goals of this system are(1) to perform metadata mapping automatically for Japanese heterogeneous humanities digital libraries and(2) to let users access multiple humanities digital libraries by using only one query input.The proposed automatic metadata mapping method produced the average mapping precision of 94.9%.We also address the metadata-related challenges facing Japanese humanities databases.展开更多
