To date, it is not known where these memories are stored in the brain, what kinds of regulatory biological factors or molecules are involved, nor why it is so difficult to stop addiction psychologically. Currently, rodent animal models, such as the self-administration and conditioning place preference / aversion paradigm are still widely used in the studies of drug withdrawal syndromes or drug-associate memories. However, the differences between humans and rodents--particularly in terms of genetics, and pathology and pharmacology--have significantly limited the application of further studies on this topic. Essentially, rodents lack the longterm or life-time memories humans possess and lose their drug-associated memory only after a few weeks of withdrawal.展开更多

The logical development from partial surgical removal of the breast is partial breast radiotherapy. Several methods of delivery have been investigated, but as yet none has been widely accepted.展开更多
