BACKGROUND Previous studies demonstrated that intensive lifestyle modification can prevent type 2 diabetes mellitus among those with impaired glucose tolerance, but similar beneficial results have not been proved among those with impaired fasting glucose levels. We investigated the efficacy of lifestyle modification on type 2 diabetes incidence among those(More)
BACKGROUND In single-cell human genome analysis using whole-genome amplified product, a strong amplification bias involving allele dropout and preferential amplification hampers the quality of results. Using an oligonucleotide single nucleotide polymorphism (SNP) array, we systematically examined the nature of this amplification bias, including frequency,(More)
Brain-derived neurotrophic factor (BDNF) belongs to the neurotrophin family, and enhances the growth and maintenance of several neuronal systems. In addition, BDNF may promote neurogenesis and protect against hippocampal volume loss in depressive disorders. Although first detected in brain, BDNF also exists in peripheral tissues and is mainly stored in(More)
PURPOSE YM155, a novel molecular targeted agent, suppresses survivin, a member of the inhibitor of apoptosis protein family that is overexpressed in many tumor types. The aim of this study was to determine the maximum tolerated dose (MTD) and to assess the safety, pharmacokinetics, and antitumor activity of YM155 in patients with advanced refractory solid(More)
Patients with alcoholism exhibit behavioral adaptations to ethanol such as tolerance, dependence, and addiction. Molecular mechanisms that underlie these altered behavioral responses to ethanol are largely unclear. We have performed oligonucleotide microarray analysis in postmortem prefrontal cortices of alcoholics. Among about 12,000 genes represented on(More)
Probucol is a unique hypolipidemic agent that increases cholesteryl ester transfer protein (CETP) activity. Enhanced CETP-mediated conversion of high-density lipoprotein (HDL) partly explains the probucol-induced decrease in HDL cholesterol and increase in plasma prebeta1-HDL (native lipid-poor HDL) concentrations. However, HDL cholesterol is reduced in(More)
IN AUTISTIC PSYCHOPATHY, Hans Asperger described that ‘the autistic personality is an extreme variant of male intelligence’. Consistent with this notion, Baron-Cohen proposed the ‘extreme male brain theory of autism’. By quoting this theory, gender dysphoria in female subjects with Asperger syndrome (AS) could be explained logically. But a literature search(More)
We studied the prevalence of intestinal parasites in animal companions in Saitama Prefecture, Japan, where no detailed data is currently available. Between May 1999 and December 2007, fecal samples were collected from 906 dogs and 1,079 cats in public animal shelters and examined by microscopy. Overall, prevalence of intestinal parasites in dogs was 38.6%(More)
It has been demonstrated previously that aldosterone increases the electrical conductance of the toad bladder in association with the stimulation of active sodium transport. In the present study the concurrent measurement of electrical quantities and ion tracer flux distinguishes effects on active and passive pathways. Lack of an effect on passive Na+ or(More)
BACKGROUND Ethanol exposure during development leads to various forms of neuronal damage. Because neural stem cells (NSCs) play a pivotal role in the development and maturation of the central nervous system, it is important to understand the effect of ethanol on NSC differentiation. In this study, we investigated the effect of ethanol on differentiation of(More)
