Individual Preparedness for Large-scale Earthquakes among International Students in Japan: A Cross-sectional Questionnaire Survey.

Introduction: Individual preparedness for large-scale earthquakes is essential for safety and security in Japan, where earthquakes frequently occur. Foreign residents in Japan face barriers to gathering disaster information, and international students are likely to be more vulnerable to the effects of earthquakes due to the shorter duration of their stay in Japan. However, no studies have been conducted on international students' individual preparedness for large-scale earthquakes in Japan.

Multi-enzyme Machinery for Chitin Degradation in the Chitinolytic Bacterium Chitiniphilus shinanonensis SAY3.

The chitinolytic bacterium, Chitiniphilus shinanonensis SAY3 was examined to characterize its chitin-degrading enzymes in view of its potential to convert biomass chitin into useful saccharides. A survey of the whole-genome sequence revealed 49 putative genes encoding polypeptides that are thought to be related to chitin degradation. Based on an analysis of the relative quantity of each transcript and an assay for chitin-degrading activity of recombinant proteins, a chitin degradation system driven by 19 chitinolytic enzymes was proposed.

Comparison of self-reported symptoms in COVID-19 patients who had or had not previously received COVID-19 mRNA vaccination.

Aberrant activation of bone marrow Ly6C high monocytes in diabetic mice contributes to impaired glucose tolerance.

Accumulating evidence indicates that diabetes and obesity are associated with chronic low-grade inflammation and multiple organ failure. Tissue-infiltrated inflammatory M1 macrophages are aberrantly activated in these conditions and contribute to hyperglycemia and insulin resistance. However, it is unclear at which stage these cells become aberrantly activated: as precursor monocytes in the bone marrow or as differentiated macrophages in tissues.

Hyperuricemia predicts the risk for developing hypertension independent of alcohol drinking status in men and women: the Saku study.
