超6000磅：葡萄牙研究人员捕捉有史以来最大鱼类_我的网站

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.。

B |     研究人员最近在《 Journal of Fish Biology》上发表了一份关于迄今为止发现的最大鱼类的报告。他们发现的生物总重量为6049磅，高约12英尺，长约11英尺，是迄今为止捕获的最大的骨鱼。

C | 该研究的第一作者告诉表示，这是一个“雄伟的标本”，如果能看到它活着那么将是不可思议的。这条新发现的太阳鱼比以前的最大鱼纪录保持者约重1000磅，后者的重量略高于5000磅，是1996年在日本千叶海岸捕获的。研究人员不确定是什么杀死了这条巨大的鱼，然而在它的头骨上发现了一个凹陷以及凹陷处有红色油漆的痕迹--可能是跟船只发生碰撞造成。

D | 不幸的是，确切的死因还不清楚。不过清楚的是，这个有史以来最大鱼类的新纪录保持者只是我们最近在海洋中的许多发现之一。此前，研究人员在海底深处发现了一种由蓝色粘液组成的生物。

E | 在此之前，研究人员首次捕捉到了一种罕见的水母的镜头。而像这种巨型标本的太阳鱼对人类来说并不完全陌生。事实上，它们可以在世界各地的水族馆中找到。如果你好奇为什么太阳鱼会叫这个名字，这跟它的形状没有关系。相反，它之所以被命名是因为它在寒冷的深海中游泳后喜欢晒太阳。
