Under ideal circumstances cryonics patients are stabilized immediately after pronouncement of legal death by restoring  blood flow to the brain, lowering temperature, and administering medications. In most cryonics cases, however, there is a delay between pronouncement of legal death and start of cryonics procedures. In some cases there are no stabilization interventions at all. Provided [...]

Various approaches are available to investigate cryoprotectant toxicity, ranging from theoretical work in organic chemistry to  cryopreservation of complete animals. Because resuscitation of complex organisms after cryopreservation is not feasible at the moment, such investigations need to be confined to viability assays of individual cells and tissues or ultrastructural  studies.
One simple model that allows for [...]
