MDCT ’unwraps’ Egyptian mummy, clearly revealing face of 3,000 year old man

02.09.2004


Multidetector computed tomography (MDCT) was used for the first time to produce a detailed 3D model of the face of an Egyptian man who lived nearly 3,000 years ago--without having to unwrap his mummified corpse, say a multidisciplinary group of Italian researchers that included physicians, anthropologists and forensic scientists.

MDCT was used to image the completely wrapped mummy of an artisan named Harwa, which had been on display at the Egyptian Museum in Torino, Italy. MDCT created 3D images, which were then reconstructed to create all the features of the mummy’s face. A physical plasticine and nylon model was sculpted based on the 3D image. The facial reconstruction revealed Harwa to be 45 years old at the time of his death and was detailed enough to reveal a mole on his left temple. "The only other way to have gotten the information we got from MDCT would have been to unwrap, destroy and otherwise alter the conservation of the bandages and the mummy," said Federico Cesarani, MD, of the Struttura Operativa Complessa di Radiodiagnostica in Asti, Italy, and lead author of the study.

CT is a noninvasive method that can provide data such as skull dimensions and dehydrated soft tissue arrangement for 3D reconstructions of the skull and body while preserving the mummy. "MDCT provides thin slices--up to 0.6 mm--in a single-shot acquisition and in a very short time, which permits high-resolution 3D reconstructions," said Dr. Cesarani.



According to the author, the technique of facial reconstruction is important for forensics, anthropology and medicine. "Police use it for identifying bodies, anthropologists to learn more about individuals in ancient societies and medicine can learn about the diseases that afflicted ancient peoples," said Dr. Cesarani.

For the lifelike Harwa facial reconstruction, the researchers avoiding guessing at the hair, beard and the color tones of the skin. They were also unable to determine just how fatty Harwa’s face was when he was alive, since fat does not leave signs in the skull, as do muscle and skin.

The article appears in the September 2004 issue of the American Journal of Roentgenology.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
