The skeletal muscle has a significant role on physical functions, and the assessment of the skeletal muscle is important in critically ill patients. Computed tomography (CT), ultrasound examination, bioelectrical impedance analysis (BIA) device, and biomarkers can all be used to assess skeletal muscle mass. CT is useful for accurately measuring skeletal muscle mass, and the measurement is conducted at the third lumbar vertebra level as the gold standard. However, the assessment using CT is done retrospectively because CT involves radiation exposure and requires patients to be transported to the examination room. On the other hand, ultrasound and BIA are noninvasive and can be used at the bedside to assess longitudinal skeletal muscle mass. However, accurate assessment requires knowledge and skills. Assessments using BIA should be carefully interpreted because critically ill patients are under dynamic fluid change and edema. Furthermore, various biomarkers for the assessment of skeletal muscle mass have been recently reported. Appropriate skeletal muscle assessment will contribute to the nutrition and rehabilitation intervention of critically ill patients so that they can return to society.

A prototype lithium-ion battery with a bis(fluorosulfonyl)imide (FSI)-based ionic liquid electrolyte was developed. The prototype was mounted on a demonstration module of the “Hodoyoshi-3” microsatellite, which was successfully launched on June 20, 2014. Qualification tests for space application, including radiation tolerance and vacuum tests, revealed negligible degradation of the ionic liquid-based lithium-ion battery (IL-LIB) cell. According to the flight data, the IL-LIB cell can exist stably in an ultra-high vacuum environment despite its thin and flexible pouch casing without any rigid anti-vacuum reinforcements. Furthermore, the power unit showed the same charge–discharge performance as that predicted by the charge–discharge behavior of an identical cell on the ground, suggesting that the IL-LIB cell maintains performance in high vacuum a microgravity environment. These results prove that LIB cells with FSI-based ionic liquids can be used as a power source for space applications.
