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.。    每周食谱          营养美味，安全可靠          2024.12.16-12.20                    人间烟火气 四季皆安然          健康是本 膳食是根          民航幼儿园的厨房每日为孩子们奉上          精心搭配的应季美食,          两餐一点是我们最用心的陪伴,          最温暖的守护                              星期一食谱          营养早餐                    青菜瘦肉红萝卜鸡蛋汤米粉、牛肉丸                    水果          砂糖橘                    美味午餐          大米饭、卤水鸡翅根、西红柿炒豆腐、红萝卜玉米马蹄脊骨汤                    健康茶点          学生奶、芝麻卷、山楂条                                                  星期二食谱          营养早餐                    牛奶芝麻糊、香菇椰菜肉包                    水果          无核红提                    美味午餐          大米饭、牛肉马蹄上肉饼、青瓜炒鸡蛋、三豆脊骨汤                    健康茶点          菜心瘦肉粥、芒芒腰果奶糕                                                  星期三食谱          营养早餐          小米淮山瘦肉粥、油麦菜胡萝卜猪肉炒面                    水果          秋月梨                    美味午餐          玉米饭、台湾卤肉、红烧南瓜、白萝卜香菜鲫鱼汤                    健康茶点          学生奶、红糖刀切馒头、混合坚果                                                  星期四食谱          营养早餐                    燕麦牛奶羹、肠仔包                    水果          苹果                    美味午餐          西葫芦瘦肉云吞面、春菜瑶柱鸡蛋瘦肉汤                    健康茶点                    小米南瓜瘦肉粥、山楂棒                                                  星期五食谱          营养早餐                    腐皮白果瑶柱瘦肉粥、豆角红萝卜猪肉炒米粉                    水果          火龙果                    美味午餐          龙利鱼五彩好味饭、雪梨银耳无花果瘦肉汤                    健康茶点          学生奶、葡萄干蛋糕、混合坚果                                                  文字 / 民航幼儿园保健          图片 / 周文娟          编辑 / 阮丽舒          排版 / 陈欢萍          审核 / 刘心慧。
