A ‘Game Changer’ For Organ Transplants: Blood Type of Donor Kidneys Altered in Breakthrough Research_我的网站

A |     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.。    　　据媒体最新报道，韩国存储芯片巨头SK海力士的工会成员周二投票否决了一项经过两个月谈判达成的初步薪资协议，超过50%的投票者投出反对票。
　　据悉，在参与投票的15045名员工中，有50.08%的人反对该协议。赞成票和反对票之间的差距仅为25票。　　SK海力士管理层与工会预计将恢复谈判，后续讨论的重点很可能围绕绩效奖金支付制度展开，而这正是劳资双方的核心分歧点所在。

B | 　　不少员工反对超过一半的奖金以股票形式发放，因为他们对SK海力士股价的波动性感到担忧。

C | 该股6月曾在AI热潮的推动下创下历史新高，但随后因市场担忧AI巨额投入可能无法获得相应回报而大幅回调。　　上周，SK海力士与其工会就2026年度薪资及集体谈判达成初步协议。这项协议包括6.3%的薪资增长，以及对SK海力士利润分享奖金计划的调整：其中40%的奖金以现金形式发放，60%以公司股份形式发放，而此前为全部由现金支付。

D | 　　在该初步协议下，奖金总额的40%将在当年以现金形式发放；其余60%以公司股票形式发放，其中占总奖金40%的股票可在当年自由变现，剩余20%的股票则递延发放。　　去年，SK海力士劳资双方约定取消利润分红上限，规定每年提取营业利润的10%作为奖金池，并设定为80%当年现金支付、20%递延两年以现金支付的发放机制。　　作为全球第二大存储芯片制造商，SK海力士正凭借人工智能应用对高带宽存储器（HBM）芯片的旺盛需求持续获得丰厚利润。随着利润暴涨，SK海力士员工希望获得更高的奖金，股东则期待分红、回购等资本回报。　　SK海力士上周宣布，其董事会已批准一项决议，拟回购并注销价值40万亿韩元（约合283亿美元）的股票。此举旨在将公司凭借AI浪潮所获得的丰厚收益回馈给投资者。　　周二，SK海力士股价大跌，截至发稿，下跌4.55%，报1595000韩元，盘中跌幅一度接近7%。　　美国芯片股抛售潮也波及了韩国芯片股。

E | 截至发稿，三星电子股价下跌约2%。　　由于英伟达财报发布前市场谨慎情绪升温，隔夜美股市场，美光科技和闪迪等芯片厂商股价暴跌。（文章来源：财联社）。
