i think your refering to the female twins from Iran? yeah they died unfortunately. the twins here in this thread should have made an attempt to come to the medical center here in houston. a good team they are. sorry to hear about their demise.:(

edit: i tried googling the story but to no avail. i think the surgery was attempted in singapor or japan and took more than 20-24 hours with several teams of doctors/nurses. a noble attempt for a good cause that had a terrible ending.
