Spatiotemporal Measurement of Arterial Pulse Waves Enabled by Wearable Active-Matrix Pressure Sensor Arrays.

Wearable pressure sensors have demonstrated great potential in detecting pulse pressure waves on the skin for the noninvasive and continuous diagnosis of cardiac conditions. However, difficulties lie in positioning conventional single-point sensors on an invisible arterial line, thereby preventing the detection of adequate signal amplitude for accurate pulse wave analysis. Herein, we introduce the spatiotemporal measurements of arterial pulse waves using wearable active-matrix pressure sensors to obtain optimal pulse waveforms.

Proximal trisomy 13. A family with balanced reciprocal translocation t(8;13) in seven members and Robertsonian translocation t(13;14) in three members.

The cytogenetic analysis of a 12-year-old retarded boy revealed a partial proximal trisomy 13, resulting from a maternal translocation t(8;13). A familial study shows this translocation in seven persons and also a Robertsonian translocation t(13q;14q) in three sons of a t(8;13) father. A review of partial proximal trisomies 13 shows a variability in the phenotypic expression.
