Autor: Toshio Itoh, Yutaro Koyama, Woosuck Shin, Takafumi Akamatsu, Akihiro Tsuruta, Yoshitake Masuda, Kazuhisa Uchiyama

Publikováno v: Sensors, Vol 20, Iss 9, p 2687 (2020)

We investigated the selective detection of target volatile organic compounds (VOCs) which are age-related body odors (namely, 2-nonenal, pelargonic acid, and diacetyl) and a fungal odor (namely, acetic acid) in the presence of interference VOCs from

Exercise Stress Electrocardiography Using the Two-Minute Jump Test in Children

Autor: Yutaro, Koyama, Masaru, Miura, Jun, Maeda, Yoshihiko, Morikawa, Hiroyuki, Yamagishi

Publikováno v: Pediatric Cardiology.

Although the treadmill and cycle ergometer are commonly used for exercise stress electrocardiography (ECG) testing, they are often difficult to perform with children. We herein evaluated the utility and safety of the two-minute jump test (2MJT) as a
