Both the Nuremberg Code and the Declaration of Helsinki indicate that animal-based research should be conducted before human experimentation, the former more unequivocally than the latter.

An interesting recent survey revealed that the donor informed consent procedures in tissue-based research should be rethought: perhaps information about research objectives is seen more as a service than a safeguard (i.e., is nice to have but not important), which would imply that bioethicists should work to ensure safeguards other than informed consent.
This study contributes to the limited body of literature on the effect of prenatal toxicants on memory and learning, and suggests that further population-based research should be undertaken to better understand the effects of low-level prenatal MeHg exposures on child memory and learning in general, and particularly aspects of memory and learning related to visual processing.
These findings suggest that the edited ER may not be representative of the general population and that alternative sampling frames for population based research should also be considered.
By email, Kraska told me that those numbers, based on his research, should be the same today, or even higher.
