Pulsed Dipolar EPR Spectroscopy and Metal Ions: Methodology and Biological Applications

ChemPlusChem, 2020
AbstractPulsed dipolar electron paramagnetic resonance spectroscopy (PDS) is a valuable method for determining biomolecular structures and their conformational changes during function. Often, this method is applied to paramagnetic metal ions that are either intrinsic co‐factors of biomolecules or introduced into biomolecules as spin labels.

Impact of changes in the methodology of external price referencing on medicine prices: discrete-event simulation

Cost Effectiveness and Resource Allocation, 2020
Background Several governments apply the policy of external price referencing (EPR), which considers the prices of a medicine in one or more other countries for the purpose of setting the price in the own country.
