Arrhythmic risk: regression, single cell biophysics, or big tissue simulations?

Posted on March 27, 2017 by Gary Mirams

On the 15th March I presented at an FDA public Advisory Committee hearing on the proposals of the CiPA initative. CiPA aims to replace the current testing for increased drug-induced Torsade de Pointes (TdP) arrhythmic risk, which is a human … Continue reading →

Should I work with IC50s or pIC50s?

Posted on June 13, 2016 by Gary Mirams

When you are expressing how much a drug inhibits something, it’s common to fit a Hill curve through a graph of concentration against % inhibition as shown here: In our case this is often ‘% inhibition’ for a given ionic … Continue reading →
