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.。    8月25日消息，据报道，美国总统特朗普近日宣布，自2027年1月1日起，将把加拿大输美汽车、卡车、汽车零部件和钢铁的进口关税提高至50%。     加拿大总理卡尼回应，称加拿大绝不会接受任何损害主权和产业利益的"附属国协议"。    这是继8月23日美国正式对约200亿美元加拿大商品征收50%关税后，美方再次升级贸易施压。

B | 此前双方旨在避免关税生效的贸易谈判已于22日宣告破裂。    特朗普在社交媒体发文，呼吁加拿大企业将生产线迁往美国以避免高额关税，并称在美国生产相关产品将享受“零关税”待遇。     他同时再次称呼卡尼为“州长”，威胁“必须有人让加拿大乖乖听话”。    卡尼24日在魁北克举行记者会，直指美方谈判态度是将加拿大视作“美国的附属”，要求加拿大产业长期处于竞争劣势。    他表示，特朗普希望通过“不公平的条件”削弱加拿大钢铁、铝和汽车三大支柱产业。“双方完全有可能达成互利协议，但前提是协议必须尊重加拿大的主权和独立，而不是为了美国的短期利益拆毁加拿大产业。”     据卡尼透露，谈判破裂并非单一原因。双方曾讨论将美国汽车关税降至15%，但美方拒绝把这一优惠扩大至中型和重型卡车，而这类车型正是福特汽车位于多伦多郊区工厂正在生产的重要产品。    更令加拿大无法接受的是，美方还要求限制加拿大与第三国签署贸易协议，并在文化及法语事务上提出附加条件。    美国贸易代表杰米森·格里尔则给出截然不同的说法。他表示，是加拿大在最后关头提出新要求，导致接近完成的协议草案流产。

C |     按照格里尔的说法，这份协议原本将降低汽车、钢铁、铝材和木材关税，并建立出口管制、数字贸易及联合关税合作机制，同时启动《美墨加协定》的正式续约谈判。该协定由特朗普第一任期推动签署，但特朗普今年拒绝续签。    就在记者会结束数分钟后，特朗普再次发文，继续称呼卡尼为“州长”，并抨击安大略省省长道格·福特，写道：“必须有人让这些小丑乖乖听话，否则加拿大将面临更严重的后果。
