二 |     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.。杭州市气象台15时54分发布台风蓝色预警信号。来了解“梅花”的最新动向和对杭州的影响。

三 | “梅花”动向今年第12号台风“梅花”（强台风级）今天（13日）17时中心位于距离杭州东南方向约576公里的海面上，预计将以每小时15公里左右的速度向北偏西方向移动，强度维持或略有加强，逐渐向浙江中北部沿海靠近，并可能于14日下午到夜里在三门到舟山一带沿海登陆。从昨天的台风“登陆或擦过”沿海地区，到今天各大数值模式对“登陆”这个趋势基本达成一致，其中原因是海上的副热带高压和大陆高压合并加强，使得台风路径上的偏西分量增加。省防指、市防指提升防台风应急响应根据《浙江省防汛防台抗旱应急预案》，省防指决定于9月13日17时将防台风应急响应提升至Ⅰ级。受台风影响，今天夜里到15 日早晨杭州东部及临安北部山区有大雨到暴雨，局部大暴雨，其它地区阴有中阵雨，局部大雨到暴雨。14 日-15 日上午最大偏北风 7～9级，部分高山区和钱塘江等江湖水面 9～10 级个别11级，梅花台风将对杭州产生严重影响。根据《杭州市防汛防台抗旱应急预案》，市防指决定于今天19时30分将防台风应急响应等级提升至Ⅱ级。杭州明天大雨到暴雨，局部大暴雨对杭州来说，台风这个路径所带来的风雨影响会比原先预计的更大，杭州市气象台15时54分发布台风蓝色预警信号。预警内容：受台风“梅花”影响，预计上城区、拱墅区、滨江区、西湖区和钱塘区所有街道今天（13日）傍晚到夜里阴有中到大阵雨，局部暴雨，明天（14日）阴有大雨到暴雨，局部大暴雨；明天最大偏北风6至8级，钱塘江等江湖水面可达9到10级，需注意防范短时强降雨可能引发的城乡积涝和大风对在建工地、临时工棚、户外广告牌、园林绿化等的不利影响。防御措施：1.政府及相关部门做好防台准备工作；2.相关水域水上作业和过往船舶采取积极的应对措施；3.紧固门窗、围板、棚架、户外广告牌、临时搭建物等易被风吹动的搭建物，妥善安置易受热带气旋影响的室外物品；4.检查城市、农田排水系统，做好排涝准备。风的影响今天夜里东北风4-5级阵风6级，部分高山区和钱塘江等江湖水面5-6级阵风7-8级，14日至15日上午最大偏北风7-9级，部分高山区和钱塘江等江湖水面9-10级、个别11级。雨的影响今天夜里到明天前期受到台风北侧倒槽和冷空气结合的影响，云团不甚紧密，杭州的雨呈现阵性特点，时、空分布不太均匀。明天后期开始随着台风靠近，杭州将受台风本体影响，雨量增大而且更加均匀。此外，山区的地形有明显的增雨作用。预计今天夜里杭州东部和临安、余杭的西北部山区阴有中到大雨，局部暴雨；明天到后天早晨杭州东部及临安北部山区有大雨到暴雨，局部大暴雨。13日15时10分雷达拼图由于大气环流复杂，目前陆上海上多低压系统，可能产生相互影响，后期路径仍存在一定不确定性。气象部门将继续密切监测分析，也请大家持续关注。西湖西溪景区所辖公园景点等场所临时关闭，船只停航受强台风影响，杭州西湖西溪景区所辖公园景点等场所临时关闭，船只停航，具体公告如下：关于西湖西溪景区所辖公园景点等场所临时关闭的公告尊敬的市民游客：根据气象部门预测，第12号台风“梅花”将于14日下午在浙江沿海登陆。为确保市民游客在极端恶劣天气下的生命财产安全，9月14日（星期三）临时关闭西湖西溪景区所属各公园景点，游船和观光车停驶。恢复时间另行通知。请广大市民、游客合理安排行程，互相转告，给您造成的不便，敬请谅解。杭州西湖风景名胜区管理委员会（杭州西溪国家湿地公园管理委员会）2022年9月13日2022年9月13日9月14日良渚博物院闭馆9月14日良渚博物院闭馆，开馆时间根据防指最新要求另行通知。请观众及时关注天气变化，及时调整安排好自己的行程，注意出行安全。如有疑问，请致电：0571-88781340。受台风“梅花”影响，良渚古城遗址公园启动台风应急响应，为保障访客生命财产安全，良渚古城遗址公园、瑶山遗址公园、老虎岭遗址公园于9月14日临时闭园一天。开园时间另行通知。
