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

一 | 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.。 Kenny 编译 3月10日下午，行动党党魁、明年将担任新西兰副总理的David Seymour在Parnell街区发生电动自行车（e-bike）事故。 Seymour说当他在路中间摔倒后遭到了路人的言语羞辱。 Advertise with us 据英文《先驱报》报道，周日傍晚时分，Seymour在参加完圣三一大教堂的活动后，骑着电动自行车离开。

三 | 所以我用力踩刹车，意识到我要侧翻了，同时还意识到哪怕如此也会撞上车，于是我更用力地猛踩刹车，然后就翻车了。” Seymour说他最终没有撞上汽车，司机也很快停下车来查看他的情况。他说除了手腕酸痛外没有受伤，路人也给他送水和询问他是否需要搭车回家。但摔倒在路中间的短暂时刻，他说自己遭受了言语羞辱。 “一个人走过来拍摄我。我觉得‘这有点怪’，然后他说‘知道吗，有时你这是罪有应得，’”Seymour说。 “他用英式口音说’看你对毛利人做了什么，你只是个脱离现实的富二代（trust-fund baby）’。

四 | ” Seymour说自己当时感到莫名其妙：“我想，我是毛利人，我没有信托基金啊？” Seymour因为提出《条约原则法案》而备受争议。他呼吁恢复《怀唐伊条约》原本的含义，同时就条约原则进行全民公投。

五 | 毛利群体广泛认为这是对毛利人自决权的削弱。 Seymour并不是今年第一个因电动车出事的政客。前国家党党魁、刚被任命新西兰交通局局长的Simon Bridges在1月发生电动滑板车事故。Bridges脸部擦伤，左手手腕骨折，被送往医院救治后打上了石膏。他说感到没发生更严重的后果让他觉得很“幸运”。目前电动自行车和电动滑板车不被归类为机动车辆。它们被允许在公路、自行车道和人行道上骑行。

六 | 出事故时最有可能伤及的是骑手而不是行人。
