P53 is tumor suppressor gene that plays important roles in regulating cell cycles in human including cell cycles arrest(inhibit cellular growth) and cell death[l]. It can be triggered by damaged DNA, ionizing agents or oxidative stress via transcription process". After p53 IS triggered, it is called "p53 transcription factor". The function of p53 transcription factor is related to programmed...
The parasympathetic nervous function in obstructive sleep apnea syndrome (OSAS) patients were quantified by using the respiratory sinus arrhythmia (RSA) impulse response magnitude. Ten participants were recruited and classified into three groups; mild (four participants), moderate (four participants) and severe (two participants) groups. Autoregressive with exogenous input (ARX) model was used to...
A noninvasive parasympathetic autonomic function monitoring system was developed. Nine healthy adults were recruited. ARX model was used to precisely separate the effect of respiration and systolic blood pressure to heart rate variability (HRV). The respiratory sinus arrhythmia (RSA) impulse response magnitude, the parasympathetic autonomic function index, was estimated during supine and standing...
Every year, several thousands of elderly people experience with falling accident. Falling is then a main problem about healthiness of elders. This paper tries to find out a simple algorithm to detect a fall. With less calculation, the device can quickly distinguish between a fall and a normal activity of daily living (ADL). As the smartphone technology is currently in very advance, it includes several...
