<p>Quercetin is one of the flavonoids and has a wide variety of cytoprotective effects. We previously reported that quercetin exerted various cytoprotective effects via nuclear factor E2-related factor 2 (Nrf2)-heme oxygenase (HO)-1 pathway. However, the mechanisms how quercetin can induce HO-1 to exhibit cytoprotective effects are poorly understood. We focused on cell membrane, which is the front line to interact with extracellular environment and plays an important role in cellular signaling. Recent studies showed that Nrf2 interacted with caveolin-1 (Cav-1), a component of caveolae, to regulate cellular anti-oxidant capacity. In this study, we investigated the involvement of Cav-1 in quercetin-induced HO-1 expression. We showed that quercetin changed the formation of lipid rafts, and the expression level of Cav-1 was decreased in cell membrane and increased in cytosol and nucleus after exposure to quercetin. The expression level of Nrf2 localized in cell membrane was also decreased, and Nrf2 was translocated to cytosol and nucleus. The extent of HO-1 induction by quercetin was as much as that by methyl-beta-cyclodextrin, a cholesterol-depleting agent. These findings suggested that HO-1-dependent cytoprotective effects by quercetin could be mediated through the disruption of lipid rafts, leading Cav-1 and Nrf2 to translocate from cell membrane and to nucleus, followed by HO-1 induction.</p>

MEMS Flow Sensor Capable of Measuring Multi-Vital Signs of Respiration, Heart Rate, and Body Temperature 国際会議

Hasegawa Y., Lee S., Matsushima M., Hasegawa S., Kawabe T., Shikida M.

21st International Conference on Solid-State Sensors, Actuators and Microsystems, TRANSDUCERS 2021 2021年6月20日 21st International Conference on Solid-State Sensors, Actuators and Microsystems, TRANSDUCERS 2021

記述言語：英語会議種別：ポスター発表

Multi-vital signs detection; respiration, heart rate, and body temperature from respiration airflow at the mouth was proposed, and three sensors patterns (flow-rate, - direction, and -temperature sensors) were formed on a single MEMS sensor. The small-sized tube type flow sensor was designed and fabricated to apply it the animal experiment, and its detection characteristics were experimentally evaluated. The flow rate sensor output followed the King's equation, and the response time of 50 ms was obtained to confirm the following oscillating breathing airflow measurement. Then, we confirmed that the fabricated sensor can measure the airflow whose temperature changes periodically. Finally, we conducted an animal experiment using rats, and confirmed that the fabricated sensor can measure three vital signs of respiration, heart rate, and body temperature from respiration.

Calibration Method for Wearable Sensor Using Airflow at Mouth for Quantitative Monitoring of Respiration and Heartbeat 国際会議

Horie K., Al Farisi M.S., Hasegawa Y., Matsushima M., Kawabe T., Shikida M.

2023 22nd International Conference on Solid-State Sensors, Actuators and Microsystems, Transducers 2023 2023年 2023 22nd International Conference on Solid-State Sensors, Actuators and Microsystems, Transducers 2023

Airflow at the mouth contains both the respiration and the heartbeat signals. In this study, we propose a calibration method for a wearable vital sensor attached on the chest using the airflow at the mouth for respiration and heartbeat quantitative monitoring. An artificial ventilator and an experimental animal, namely rat, were introduced as test benches prior to human clinical experiment. As a proof of concept, a micro-electro mechanical systems (MEMS) airflow sensor and a wearable accelerometer were implemented to both the test benches. The velocity output of the piston motion measured by the wearable sensor conformed with the airflow rate output, and the obtained results indicated that the wearable sensor can monitor not only the frequency but also the respiratory volume or heartbeat strength.
