![]() “In particular, we are interested in craniofacial structures, which have undergone a number of adaptations in head shape, eye placement and facial structure that allow us to house larger brains, walk upright and even use our larynx for complex speech.” “We are trying to understand the regulatory changes in our DNA that occurred during recent evolution and make us different from the great apes,” said Joanna Wysocka, PhD, associate professor of developmental biology and of chemical and systems biology. In particular, the researchers found that chimps and humans express different levels of proteins known to control facial development, including some involved in jaw and nose length and skin pigmentation. The key lies in how genes involved in facial development and human facial diversity are regulated - how much, when and where the genes are expressed- rather than dissimilarities among the genes themselves. ![]() Now researchers at the Stanford University School of Medicine have begun to pinpoint how those structural differences could arise in two species with nearly identical genetic backgrounds. Herold died last year of an aneurysm.The face of a chimpanzee is decidedly different from that of a human, despite the fact that the apes are our nearest relative in the primate tree. Ms Nash's family is suing the estate of the chimpanzee's owner, Sandra Herold, for $US50 million ($A49.2 million) and wants to sue the state for $US150 million ($A147.7 million), claiming officials failed to prevent the attack. "This has really given my mum the hope to move forward, a chance at a life again." "What they've done for us is just so amazing," she said. Ms Nash said she's hoping to attempt another double hand transplant one day.Īsked by Today what she would say to the donor's family, Ms Nash's daughter, Brianna, said she'd tell them how grateful she is. It was the third full face transplant in the US.īut doctors later had to remove the hands because of complications that developed when Nash caught pneumonia. She received skin, underlying muscles, blood vessels, nerves, a hard palate and teeth from a dead person who hasn't been named. In late May, she underwent a full face and double hand transplant in Boston. ![]() She could eat only pureed food, and she was barely understandable when she talked. Ms Nash was left with no eyes and only a small opening where her mouth once was. The animal, named Travis, ripped off Ms Nash's nose, lips, eyelids and hands before being shot to death by police. The show aired footage of Ms Nash in a hospital bed, nodding to visitors, her face smooth and features appearing nearly normal. "I am tremendously grateful to the donor and her family." I will be able to kiss and hug loved ones. I will have lips and will speak clearly once again. "I will now be able to do things I once took for granted," she said. In a statement released by the hospital, Ms Nash thanked all the doctors, nurses and other medical experts who helped her over the past two years. Ms Nash, 57, didn't appear on Today because relatives said she was too weak to be interviewed. ![]() The pictures of Charla Nash were first shown on NBC's Today show and were later released by Brigham and Women's Hospital in Boston, where she had face transplant surgery in May. THE new face of a woman who was mauled by a chimpanzee two years ago has been revealed for the first time in photos showing a startling transformation. ![]()
