Influence of Age and Central Hypertension on the Form Factor Needed to Estimate Mean Aortic Pressure, and Its Implications for Pulse Pressure Amplification: A Secondary Data Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Mean aortic pressure (MAP) plays a pivotal role in both cardiovascular dynamics and the noninvasive estimation of systolic aortic pressure. MAP can be estimated by adding a fraction of the pulse pressure (PP) to the diastolic aortic pressure ...

Signal Separation Using a Mathematical Model of Physiological Signals for the Measurement of Heart Pulse Wave Propagation With Array Radar

IEEE Access, 2020
The arterial pulse wave, which propagates along the artery, is an important indicator of various cardiovascular diseases. By measuring the displacement at multiple parts of the human body, pulse wave velocity can be estimated from the pulse transit time.

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.
