‘Animal-human’ cornea transplant by Chinese doctors

BEIJING: Doctors of Shandong Eye Institute in China, on Monday, declared  the successful operation of a bio-engineered pig cornea into a human eye.

“The patient’s vision has gradually improved after a three month recovery period, which means the transplant was a success,” said Zhai Hualei, director of Shandong Eye Institute’s cornea division.

Wang Xinyi, 60, was suffering  from  corneal ulcer. He could only see moving objects within 10 cm.

“The doctors originally told me that my father might lose sight in one eye because there are not enough cornea donations,” Wang’s son said.

The transplant used a bio-engineered cornea named Acornea, the first such product to be licensed by the China Food and Drug Administration in April.

“With the pig cornea as the main material, the product is devoid of cells, hybrid proteins, and other antigens. It retains a natural collagen structure with remarkable bio-compatibility and biological safety,” said Zhai.

Cornea diseases are one of the biggest causes of blindness in China. New cases are increasing by 100,000 each year, however, only about 5,000 people receive a cornea transplant annually.

Beijing Tongren Hospital and Wuhan Xiehe Hospital, among others, have been conducting clinical trials of Acornea since 2010, recording a success rate of 94.44 percent, similar to the results seen with donated human corneas.(IANS),(Image: the-newshub.com)

After two cases of cars exploding in China, electric vehicle (EV)-maker Tesla is planning to upgrade the battery systems of some of its cars.

The decision comes after a Tesla vehicle caught fire in Hong Kong last week, marking the second time a Tesla was found burning recently, CNN reported on Saturday.

“Out of an abundance of caution, we are revising charge and thermal management settings on Model S and Model X vehicles,” the report quoted the company spokesperson as saying.

Last month, a viral footage showed a Tesla Model S appearing to explode at a car park in Shanghai.

The company said it sent a team to the site of the Hong Kong fire to investigate the incident alongside the Chinese authorities.

EVs are generally far less likely to catch fire than gasoline vehicles.

The EV-maker also said its battery packs are designed “so that in the very rare instance a fire does occur, it spreads very slowly and vents heat away from the cabin, alerting occupants that there is an issue and giving them enough time to exit the vehicle,” the spokesperson added.
