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.。
二 | 根据国际足联官方排定的大赛成绩表（第5到第48名），亚洲球队占据了榜末五位中的三个席位（0分净负11球的伊拉克队垫底，0分净负9球的乌兹别克斯坦是倒数第三，0分净负5球的约旦是倒数第五）。伊朗队3战保持不败，拿到3分，在48强中排名第33位——距离淘汰赛真的就差一步。
三 | 在12个小组第三，8支可以跻身淘汰赛的赛制里，伊朗队是成绩第9好的小组第三，未能晋级。而且伊朗队几乎就绝杀拿下了比赛，然而因为半个脚掌的越位，伊朗队最终无法更进一步，着实令人惋惜。作为伊朗队出色表现的代表，36岁的边后卫雷扎扬，获得了举世称赞。他在对阵新西兰之战里，打入一球，助攻一次，成为世界杯正赛历史上，第一位单场比赛传射建功的伊朗球员。随后，他在伊朗队打平埃及之战里再度破门，赛后夺取全场最佳球员。雷扎扬参加了2018俄罗斯世界杯、2022卡塔尔世界杯、2026美加墨世界杯，他还在卡塔尔世界杯里，伊朗队2-0击败威尔士之战里取得破门。年轻时的雷扎扬，被亚足联官方赞为“速度快、体力好，爆发力是亚洲顶级”，如今已经36岁的他，速度、爆发力很难再像年轻人那般生猛，为何还能有如此出色的表现？大赛后，雷扎扬通过社媒发布了一系列图片，人们才找到答案。这位球员世界杯后没有休息，而是去西班牙寻找场地积极的训练，他堪比健美运动员的身材，就是他用苦练、汗水浇灌出的成果。这是一位非常珍惜机会，深知每一次训练、每一场比赛的机会都来之不易，所以会拼尽全力去应对的球员！根据伊朗多家媒体的介绍，已经36岁的雷扎扬，收获了西班牙阿尔梅里亚等队的邀请，他有可能在这个年纪去欧洲联赛踢球。这不仅仅是因为他在世界杯上，无论是进攻、防守，都有着可圈可点的表现，这也是因为，他在大赛结束后没有去度假休息，而是第一时间就投入训练的职业态度，让他收获了业界的好评和欣赏。雷扎扬的职业生涯大部分时间都是在中东的联赛（伊朗、卡塔尔）度过，只是在2017-18赛季短暂效力过比利时联赛。如今他已是36岁的老将，反而因为表现出色，获得了欧洲球队的青睐，这种“逆生长”令人赞叹，也成为2026世界杯期间，亚洲足球的一抹亮色。看足球上咪咕视频！（罗掌柜）
