A 10-Year Study of the Trend of Accidental Falls in the Elderly in a Japanese Hospital.

Elderly people are prone to falls. We established the Falls Prevention Working Group (FPWG) at our hospital in 2015 to reduce the number of falls during hospitalization. This study compared the trend of in-hospital falls in the elderly in two time periods (2008/9 and 2018/9) and determined the effects of FPWG-implemented measures.

Immobilization of Trypsin from the Subphase to the Langmuir Monolayer of Fluorocarbon-Modified Single-Walled Carbon Nanotube and Its Activity Maintenance.

Single-walled carbon nanotubes (SWCNTs) synthesized by the improved arc discharge method were modified with a fluorocarbon chain, and the maintenance of trypsin activity upon adsorption from the subphase to the interfacial monolayer of SWCNTs was evaluated. The adsorption of trypsin on the fluorocarbon-modified SWCNT monolayer was confirmed by morphological and spectroscopic evaluations. Fiber morphology studies revealed that the fluorocarbon-modified SWCNT monolayer was covered by trypsin, and a trypsin-derived amide band was detected in the infrared spectra of the multilayers.
