Neural stem cells are multipotent and self-renewing cells that can differentiate into new neurons and hold great promise for treating various neurological disorders including multiple sclerosis, Parkinson’s disease, and Alzheimer’s disease. Small molecules that can trigger neurogenesis and neuroprotection are particularly useful not only because of their therapeutic implications but also because they...
Heartbeat and respiration are fundamental vital signs used for estimation of patient's status. In this study, we have proposed a simple method to monitor the heartbeat and respiration based on displacements of human body which occur due to periodic heartbeat and breathing. The proposed system consists of an aircushion, pressure sensing hardware and extraction algorithm. The displacements of subject...
In this paper, we have suggested a novel method to monitor respiration and heart rate using a PPG pillow during sleep. The proposed method employs a pillow containing a reflective type PPG sensor and a simple extraction algorithm. The PPG pillow was placed under the back of a neck to acquire PPG signal on the assumption that the subjects hardly change their position. The results showed considerable...
