Article: Reports summarize life sciences study results from Imperial College London.

Data detailed in 'Investigation of endothelial function by pulse contour analysis: a protocol for drug administration and timing of pulse contour assessment' have been presented. "Pulse contour analysis (PCA) obtained by finger photoplethysmography produces a digital volume pulse (DVP) including an inflection point in its down-slope. The reflection index (RI: ratio of the inflection point height over the maximal DVP) is responsive to vasodilatation," scientists in London, the United Kingdom report (see also Life Sciences).

"We aimed to optimize the drug dose and time interval for assessing endothelial function using PCA in healthy volunteers and patients with ...
