一 |     8月26日讯 据米兰新闻网报道称，加拉塔萨雷准备提高对莱奥的报价，将在5000万欧左右。

二 |     Breakthrough new research could significantly increase supply of organs for people with rarer blood types waiting for a transplant, reported The Guardian.,A team of scientists from the University of Cambridge have successfully altered the blood type of three donor kidneys. By flushing blood infused with a special enzyme through a human kidney the scientists removed the blood type markers lining the blood vessels of the organ.,The procedure required using a device that is connected with a donor’s kidney to pass oxygenated blood through it - a normothermic perfusion machine. As a result, the organ was converted to type O, considered the universal donor.,Blood Group Compatible,As the blood type of a donor must be compatible with the recipient’s, the new development could increase the supply of kidneys available for transplant.,A kidney from someone with blood type A cannot be transplanted to someone with blood type B, or visa versa. In such a case, the receiving body’s immune system would reject the new organ, interpreting the different blood type as foreign.,So changing the blood type to the universal O would mean the donor organ could be used for people with any blood type.,“Our confidence was really boosted after we applied the enzyme to a piece of human kidney tissue and saw very quickly that the antigens were removed. After this, we knew that the process is feasible, and we just had to scale up the project to apply the enzyme to full-size human kidneys,” Serena MacMillan, a PhD student at the University of Cambridge, said.,Scientists involved in the research, funded by charity Kidney Research UK and due to be published in the British Journal of Surgery, clarified that the outcome might have particular implications for minority ethnic groups.,Science & TechGood News for ABs: Scientists Can Now Change People's Blood Type21 February, 16:34 GMT,Some blood groups such as O Rh positive and B Rh positive are more prevalent among black, Asian and minority ethnic communities. To complicate matters further, some rare blood types are only found within the black, Asian and minority ethnic communities,This typically places them at a disadvantage, as they struggle to find a match. With low donation rates from these populations, stressed the researchers, sometimes such patients wait for as long as over a year for a compatible donor. They cited figures from 2020-21 showing that just over 9% of total organ donations in the UK came from black and minority ethnic donors. On the other hand, black and minority ethnic patients make up 33% of the kidney transplant waiting list.,“It’s very exciting to think about how this could potentially impact so many lives,” added Serena MacMillan.,The “potentially gamechanging” research was applauded by Dr Aisling McMahon, the executive director of research at Kidney Research UK.,The scientists will now test the reintroduction of other blood types and observe how the novel approach in clinical settings.。加拉塔萨雷准备重新对莱奥发起冲锋。这家土耳其俱乐部正在准备向AC米兰提交一份新报价，意在尽快与红黑军团达成协议。现在是这项交易以及决定莱奥未来的决定性时刻，这一悬念自5月底以来就一直是舆论焦点。在经历了一个月前首份3500万欧元的报价后，加拉塔萨雷决定不再犹豫，准备呈上一份新的正式报价，并将在极短时间内正式送达米兰。这份报价将在5000万欧元左右，外加一些尚需协商的附加浮动条款；但这笔核心金额将是解开局面的关键。此前在新闻层面，门德斯的运作曾带出了热刺和阿斯顿维拉的关注，但这些关注均未转化为给米兰及球员本人的正式报价。因此，这场夏季转会肥皂剧正迎来最关键的时刻：加拉塔萨雷面临着巨大的媒体舆论与球迷压力，迫切希望引进一位巨星来到伊斯坦布尔，他们已准备打破僵局并结束观望，全速拿下莱奥，他自始至终都是该俱乐部在今夏转会窗的首要目标。现在各方都在等待包含正式报价的邮件以及米兰的最终抉择；事已至此，红黑军团不能冒险将一位如此难以驾驭的球员留在队内。
