A study to visualize the generation of droplets and aerosols during singing in Japanese

A research group led by Lecturer Hideaki Kato of the Yokohama City University Hospital Infection Prevention and Control Department observed the distance of droplets dispersed and the amount of aerosols generated during singing and vocalization in Japanese.

Expansion of droplets during speaking and singing in Japanese

During the COVID-19 pandemic, a number of infection clusters associated with choral singing have been reported. Singing generates droplets and carries the risk of spreading infection. However, no reports have explored droplet flight and aerosol production rates by singing and speaking in Japanese.

Mechanistic insights into intramembrane proteolysis by E. coli site-2 protease homolog RseP

Site-2 proteases are a conserved family of intramembrane proteases that cleave transmembrane substrates to regulate signal transduction and maintain proteostasis. Here, we elucidated crystal structures of inhibitor-bound forms of bacterial site-2 proteases including Escherichia coli RseP.

Fragmentation of Ambulatory Care among Older Adults: an Exhaustive Database Study in an Ageing City in Japan

Objectives Continuity of care is a core dimension of primary care, and better continuity is associated with better patient outcomes. Therefore, care fragmentation can be an indicator to assess the quality of primary care, especially in countries without formal gatekeeping system, such as Japan. Thus, this study aimed to describe care fragmentation among older adults in an ageing city in Japan.
