This study was conducted to examine the characteristics and use of dietary supplements by preschool children in Japan. A survey was conducted among 2,125 parents of preschool children to discover the status of dietary supplement use and their attitudes towards supplement use by their children. Logistic regression models were used to determine which(More)
Repeat-induced point mutation (RIP) is a process that detects DNA duplications and peppers their sequences with C:G to T:A transitions in the sexual phase of the life cycle. So far, this unique mechanism has been identified as a currently active process in only two fungal species, Neurospora crassa and Podospora anserina. To determine whether a RIP-like(More)
We conducted a questionnaire-based study in collaboration with a Japanese trisomy 18 parental support group. Sixty-five children (female, 68%) with full trisomy 18 were evaluated. Diagnosis was made prenatally in 17% (11/65) and 57% (37/65) were born following a cesarean. The mean gestational age at delivery was 38 weeks and 6 days, and the mean birth(More)
Sphingosine-1-phosphate (S1P) is a well-known signaling sphingolipid and bioactive lipid mediator. Recently, it was reported that S1P inhibits osteoclast differentiation and bone resorption. On the other hand, S1P effects on osteoblasts and bone formation are little known. In this study, we investigated the effects of S1P on osteoblasts, using two(More)
The rate of chain elongation of palmityl-CoA to stearyl-CoA in rat liver microsomes was studied in connection with the nutritional status of the rats. The microsomal chain elongation activity, which had been decreased by starvation for 48 hr, was rapidly increased to a high level on refeeding. The apparent Km value for malonyl-CoA in both normal and refed(More)
Epidemiologic and ecologic studies suggest that dietary fat plays an important role in the development of obesity. Certain Wistar rat strains do not become obese when fed high-fat diets unlike others. In a preliminary study, we confirmed that Slc:Wistar/ST rats did not become obese when fed high-fat diets. The mechanisms governing the response of hepatic(More)
We measured and compared the activities of various kinds of proteinases, such as cysteine, serine, aspartic, and metalloproteinases, in synovial fluids of 16 patients with rheumatoid arthritis (RA) and 18 patients with osteoarthritis (OA). More than 19-fold higher activity of cathepsin B and about 6-fold higher activity of prolylendopeptidase, compared to(More)
