Selective amnesia -- How a traumatic memory can be wiped out

Estrogen protects liver after traumatic injury

Researchers have identified the receptor pathway used by estrogen to decrease liver injury after trauma and hemorrhage. The related report by Hsieh et al, “G protein-coupled receptor 30-dependent protein kinase A pathway is critical in nongenomic effects of estrogen in attenuating liver injury after trauma-hemorrhage,” appears in the April issue of The American Journal of Pathology and is accompanied by a commentary. more
