Researchers in the United States have succeeded in making a working kidney and transplanting it into rats. According to the journal Nature Medicine, this process known as Bioengineering could potentially make organ transplants obsolete in the future. It involves taking a rat kidney and stripping it of its cells, leaving a shell which's then relined with renewed cells from newborn rats and blood vessel running cells from human donors.
美国研究人员成功研制出一个可操作的肾脏并将其移植到老鼠体内。据自然医学杂志报道,此过程被称之为生物工程,有望在将来取代传统的器官移植。它只需要取老鼠的肾脏,剥离掉其细胞只留下一层外衣,然后再向外衣里注入新生老鼠的细胞和血管方便导入捐献者的细胞。
China's state news agency says 11 fresh cases of the new strain of bird flu have been reported across the country on Sunday. Two new deaths from the new virus were also reported in Shanghai with new strain named new H7N9 first appeared last month. A total of 13 people have now died. A spokesman for the World Health Organization Michael O'Leary said there was no evidence that the virus was transmitted from human to human. "As far as we know, all the cases are individually infected in a sporadic and not connected way. There have been a couple of family clusters that have been investigated but the cases in general have been sporadically spread around the country, and the source of infections remains under active investigation."
