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

A |     IT之家 7 月 21 日消息，小米现已在海外电商平台 Flipkart 预热 Poco M8 Power 5G 手机。    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.。新机主打超长续航，拥有橙色配色，即将在印度发布。         官方预热信息显示，这款手机将配备一块大容量电池，具体容量暂未公布。外观方面，该机将采用橙色方案，带有后置双摄。         结合消息人士 Kacper Skrzypek 此前发掘小米澎湃 HyperOS 代码库，该机很可能是 REDMI Note 17 的换标版本。         IT之家了解到，REDMI Note 17 手机配备 7 英寸 OLED 屏，分辨率为 2396*1080，支持 120Hz 高刷，峰值亮度可达 1800nits。拥有 8000mAh 金沙江电池，支持 45W 有线快充、22.5W 有线反向充电，搭载第四代骁龙 4 移动平台，采用 4nm 制程工艺。
