Identifying Glucose Metabolism Status in Nondiabetic Japanese Adults Using Machine Learning Model with Simple Questionnaire.

We aimed to identify the glucose metabolism statuses of nondiabetic Japanese adults using a machine learning model with a questionnaire. In this cross-sectional study, Japanese adults (aged 20-64 years) from Tokyo and surrounding areas were recruited. Participants underwent an oral glucose tolerance test (OGTT) and completed a questionnaire regarding lifestyle and physical characteristics.

Actual consumption amount of personal care products reflecting Japanese cosmetic habits.

Safety assessments of cosmetics are carried out by identifying possible harmful effects of substances in cosmetic products and assessing the exposure to products containing these substances. The present study provided data on the amounts of cosmetic products consumed in Japan to enhance and complement the existing data from Europe and the United States, i.e.

Carbon nanohorns accelerate bone regeneration in rat calvarial bone defect.

A recent study showed that carbon nanohorns (CNHs) have biocompatibility and possible medical uses such as in drug delivery systems. It was reported that some kinds of carbon nanomaterials such as carbon nanotubes were useful for bone formation. However, the effect of CNHs on bone tissue has not been clarified.

Genome sequence of the lager brewing yeast, an interspecies hybrid.

This work presents the genome sequencing of the lager brewing yeast (Saccharomyces pastorianus) Weihenstephan 34/70, a strain widely used in lager beer brewing. The 25 Mb genome comprises two nuclear sub-genomes originating from Saccharomyces cerevisiae and Saccharomyces bayanus and one circular mitochondrial genome originating from S. bayanus.

Allophanate hydrolase of Oleomonas sagaranensis involved in an ATP-dependent degradation pathway specific to urea.

The first prokaryotic urea carboxylase has previously been purified and characterized from Oleomonas sagaranensis. As the results indicated the presence of an ATP-dependent urea degradation pathway in Bacteria, the characterization of the second component of this pathway, allophanate hydrolase, was carried out. The gene encoding allophanate hydrolase was found adjacent to the urea carboxylase gene.

Enzymatic characterization of a prokaryotic urea carboxylase.

We identified the first prokaryotic urea carboxylase (UCA) from a member of the alpha subclass of the class Proteobacteria, Oleomonas sagaranensis. This enzyme (O. sagaranensis Uca) was composed of 1,171 amino acids, and its N-terminal region resembled the biotin carboxylase domains of various biotin-dependent carboxylases.

Oleomonas sagaranensis gen. nov., sp. nov., represents a novel genus in the alpha-Proteobacteria.

A Gram-negative bacterium was previously isolated from an oil field in Shizuoka, Japan, and designated strain HD-1. Here we have performed detailed characterization of the strain, and have found that it represents a novel genus. The 16S rRNA sequence of strain HD-1 displayed highest similarity to various uncultured species (86.
