更为关键的是,此前全球范围内并无经Ⅲ期临床试验确证疗效的CIN2非手术治疗产品,患者要么面临长期随访的癌变风险,要么被迫接受创伤性手术,难以实现“早干预、少损伤”的防控要求。APL-1702的出现,让CIN2真正成为宫颈癌防控的“黄金节点”,将推动临床诊疗重心向CIN2阶段前移,助力宫颈癌防治体系实现跨越式升级。
The NCAR team spent the next ten years working on the problem with researchers at airlines, universities, the F.A.A., NASA, and NOAA—the National Oceanic and Atmospheric Administration. “It was a national imperative,” Cornman said. Luckily, the beginnings of a solution were already in place. The team at NCAR had used sophisticated new Doppler radar systems to detect microbursts. When those were added to the wind detectors already installed at many airports, and the two systems were integrated with software that Cornman developed, microbursts could be detected as they were happening. “A problem where hundreds of people were dying suddenly stopped,” Cornman said. The last time a commercial flight was downed by a microburst in the U.S. was in 1994.
Still, for all the clever innovations that have made cabins safer, the economics of flight have also potentially made them more dangerous. Planes once furnished with plush recliners and wide-open aisles are now packed with more passengers each year. Those in first class lounge in lie-flat seats with built-in air bags in their seat belts, while those in economy sit shoulder to shoulder and knee to seat back, hoping they won’t crack heads in a storm. In 2021, the F.A.A. published a study on emergency evacuations which concluded that current cabin-seating requirements “can accommodate and not impede egress for 99% of the American population.” But last year a review panel from the National Academies of Sciences, Engineering, and Medicine found that the study was flawed. The F.A.A. trials had included only volunteer passengers with no physical limitations, and none of them was over sixty years old.,推荐阅读clash下载获取更多信息
