A ‘Game Changer’ For Organ Transplants: Blood Type of Donor Kidneys Altered in Breakthrough Research_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.。    Teens in the city of Prayagraj in India's Uttar Pradesh are making headlines for manufacturing crude bombs from easily available explosive materials for just INR 60 to 80 ($1.01), and hurling them at educational institutions and shops.,As many as 35 students, including 27 minors, have recently been arrested in Prayagraj after learning how to make bombs by watching viral videos on social media and putting their newly-acquired skills to practice. The adult students have been sent to jail, according to the police.,Shocked by the details that emerged during the interrogation of the students, Shailesh Kumar Pandey, Superintendent of Police in Prayagraj city, told Indian news agency IANS that the minors between 14 and 17 years of age have become experts in making a low-intensity crude bomb within minutes.,"They would take electrical tape from their houses, and purchase two low or high-intensity firecrackers from the market. Then they collect its explosive material on a piece of paper, add pieces of glass bottle and stones, and wrap it with electrical tapes," Pandey added.,During the interrogation, the cyber unit of the Prayagraj District Police found that students would coordinate the production of bombs through social media groups and share videos on how to make them at home via these groups.,Several such groups are now under scrutiny, with the authorities asking the parents of the adult students sent to jail to talk to their children.,At least 10 such groups, as well as student profiles on social media, are now being monitored by police.。
