Researchers at the Massachusetts General Hospital in Boston, USA, say that this "ear" is as elastic as the real ear. The researchers believe that this technology will one day be used to help patients who have lost or damaged their outer ears.
Tissue engineering is a rapidly developing field in the medical science research community. Researchers cultivate replacement organs in the laboratory with a view to replacing damaged human organs with them. The purpose of the American research team responsible for cultivating artificial ears is to help those who are born with ear deformities or lose their ears in an accident to regain their ears.
Previously, the researchers had also cultivated artificial ears, but only bred artificial ears of the same baby ear size on mice.
The scientists extracted live cells from cattle and sheep, and then cultivated the cells on a three-dimensional titanium frame resembling a human ear and transplanted them into a mouse.
Dr. Thomas Cervantes, the head of the research team, said: "We have cultivated the first artificial ears in mice with the same size as real human ears." He said that this research is a clinical experiment that uses tissue engineering to cultivate human ear A big step forward. Cervantes expects that human clinical trials will be possible in about five years.
Sunglasses can prevent ultraviolet rays from sunlight. Ultraviolet rays can damage the cornea and retina, and sunglasses can completely eliminate ultraviolet radiation. Sunglasses can prevent strong light. Light reflected from the sun will damage the retina. High quality sunglasses can filter up to 97% of the eye rays to avoid injury. Sunglasses can prevent glare. It can reflect large amounts of light, and the bright spots that it produces will disturb the line of sight or hide objects. Sunglasses can completely eliminate such glare with polarizing technology. There is also the role of beauty decoration. Sunglasses are an indispensable decoration for fashion.
