Abstract: An artificial liver support system is described herein which comprises cryopreserved hepatocytes having an initial viability of 80-99% and a metabolic activity 50-80% of fresh hepatocytes. Further disclosed are hepatocytes cryopreserved by dispensing hepatocytes into freezing containers, freezing the containers from between minus 50 to minus 90 degrees Celsius, storing the containers in liquid or vapor nitrogen, thawing the cryopreserved hepatocytes when ready for use and removing residual cryoprotectant media.

Abstract: Substituted-1-arylpyrrole compounds of general formula (I) below, are useful as pesticides, in particular for the control of insects, arachnids, and nematodes.
