Long-term hemodynamic responses and reverse remodeling after pharmacotherapy in HFpEF versus HFrEF: a systematic review and meta-analysis.

The acute response to therapeutic afterload reduction differs between heart failure with preserved (HFpEF) versus reduced ejection fraction (HFrEF), with larger left ventricular (LV) stroke work augmentation in HFrEF compared to HFpEF. This may (partially) explain the neutral effect of HFrEF-medication in HFpEF. It is unclear whether such differences in hemodynamic response persist and/or differentially trigger reverse remodeling in case of long-term afterload reduction.

Monitoring of drinking water quality: a preliminary approach by an electronic tongue based on functionalized polymer membrane electrodes.

Functionalized polymer membrane electrodes based multichannel sensor is used as an electronic tongue to monitor the drinking water (DW) quality simply by measuring the surface electric potential with respect to Ag/AgCl reference electrode in 1 mM aqueous KCl.
