Gap between guidelines and clinical practice in heart failure with reduced ejection fraction: Results from TSOC-HFrEF registry.

Background: Heart failure (HF) is a global health problem. Guidelines for the management of HF have been established in Western countries and in Taiwan. However, data from the Taiwan Society of Cardiology-Heart Failure with reduced Ejection Fraction (TSOC-HFrEF) registry showed suboptimal prescription of guideline-recommended medications.

An enzyme-linked immunosorbent assay on a centrifugal platform using magnetic beads.

An automated, disk-based, enzyme-linked immunosorbent assay (ELISA) system is presented in this work. Magnetic beads were used as the antibody carriers to improve the assay sensitivity and shorten the reaction time. The magnetic module integrated on the system is capable of controlling the magnetic beads to either move in the incubation stage or immobilize at a specific location during washing stage.
