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

一 | 本文来自微信公众号：认真学，作者：Seki菇菇，原文标题：《日本第一位女首相上任后，二手市场煤炉卖疯了？!》，题图来自：AI生成日本第一位女首相诞生了，相信大家前两天已经被这条新闻刷屏了。 10月22日我在雅虎新闻和NHK上看各种关于高市早苗接下来会有什么动作的报道时，被一条二手市场卖疯了的新闻吸引走了。

二 | 二手交易平台メルカリ（煤炉）上，“高市早苗”相关的物品被炒到了天价——报纸号外卖到六千多日元，高市早苗应援的毛巾成了新一轮的稀有收藏品。 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.。等一下，都是什么东西？报纸和毛巾？是的，奈良新闻和读卖新闻在21日发行的首相就任号外，还有高市早苗当选自民党总裁时的号外也被拿出来卖了，有人标价高达6600日元一份，原价也就200日元左右。

三 | 还有在2021年她首次参选总裁时发售的“早苗毛巾”（定价2000日元）也被大量拿出来卖。最高价的是她在1992年出版的名为“30歳のバースディ―その朝、おんなの何かが変わる”（30岁的生日——那天早晨，女人的某些东西改变了）的书，标价199980日元（含运费），约为9600RMB。还好，至今没卖出去，商品下面的评论区里有学生真心想买，但是将近20w太贵，想划价到2w日元，卖家出面表示不如去图书馆借来看。

四 | 不过，目前最受欢迎的是围巾毛巾，多款已经售罄。原因在于，2021年发售的“早苗毛巾”在35分钟内就售出500条，之后又紧急加印1000条，堪称超级稀有品。

五 | 真是在这个万物皆可二手的日本里，连首相也成了消费的一部分啊。

六 | 这场看似荒诞的交易，却刚好折射出日本社会里一种非常典型的文化现象：把时代事件转化为收藏记忆的能力。在日本，几乎每一次“历史时刻”发生时，二手网站上都会成为另一种“现场”。 2019年改元为“令和”时，各地报社发放的号外报纸被民众一抢而空，随后大量出现在二手平台上，有的报纸版本因为地方限定，还被炒到几千日元。 2022年安倍晋三遇袭身亡后，相关的纪念品比如演讲用的宣传单、签名书籍、徽章等被大量转卖，价格飙升数倍。甚至有人把当日现场的照片上架，引发道德争议。感觉日本人似乎很喜欢用“实物”去留住瞬间，比如一张报纸、一条毛巾、一枚纪念徽章，都是他们与时代之间的触点。换句话说，煤炉等二手市场上那些被高价转卖的物品，不只是商品，它们代表了一种“我见证了”的参与感。这也是日本消费文化里非常典型的一面：当某个事件成为全民话题时，它就会被迅速商品化，并通过转卖市场完成“纪念仪式”。但更多的我感觉还是想趁热度赚一笔吧，有意思的是居然真的有人买单。

七 | 有人出于好奇，有人想“收藏历史”，还有人只是单纯地觉得“限量＝值得”。毕竟在日本，“限定”“稀有”这两个词本身就带着魔力，它让一张免费报纸也能摇身一变成为拍卖品。买与卖的人动机不同，但共同构成了这个国家独有的“事件消费文化”——把一场新闻，变成一次消费，也变成一种纪念的方式。啊，好吧，只能说一句不理解但尊重。
