A | SAN SALVADOR, El Salvador -- El Salvador sent more than 4,000 security forces into three communities on the outskirts of the capital to root out gang members Wednesday, as President Nayib Bukele prepared to request another extension of emergency powers to combat crime.Bukele announced the pre-dawn operation in a slickly produced video posted to the platform X. Soldiers and police were sent to surround the densely populated communities of Popotlan, Valle Verde and La Campanera outside San Salvador, the president said.“We are not going to stop until we capture the last terrorist that remains,” Bukele wrote, using a phrase that typically refers to members of gangs who have been accused of drug trafficking, protection rackets and extortion. “We won’t allow small remnants to regroup and take away the peace that has cost so much.”Bukele has used emergency powers granted after a surge in gang violence i n March 2022 to wage an all-out offensive against the country’s powerful street gangs. More than 72,000 alleged gang members or affiliates have been jailed. The crackdown has allowed a renewal of everyday life in the public spaces of Salvadoran communities once cowed by the gangs, but critics say the arrests have been made without due process and that thousands of innocents have been swept up in the effort.The emergency powers suspend some constitutional rights, such as being told why you’re being arrested and access to an attorney. The security measures remain highly popular with Salvadorans, but international human rights organizations and some foreign governments are highly critical.Security forces have executed similar operations over the past year and a half. They typically set up checkpoints at the entrances to communities, stopping and questioning drivers and searching their vehicles, while other forces search door to door for gang members.La Campanera has been known as one of the country’s most violent areas. Some 10,000 people live there and for years were controlled by the Barrio 18 gang.In December 2022, more than 10,000 members of the security forces entered La Campanera and other communities of the Soyapango municipality rounding up gang members.。
B | 近日，由上海之江生物研发的“小青耕”全自动核酸检测平台获国家药监局批准上市，成为目前国内体积最小、自动化程度更高的一体化磁珠法+荧光PCR核酸检测系统，这一台设备仅重45Kg，可放置桌面，能自动化完成样本管开关盖、移液前处理、纳米磁珠法核酸提取、PCR体系构建、荧光PCR扩增等核酸检测全流程，从而实现无人值守，以此来缓解目前核酸检测专业人员数量不足的问题。“小青耕”全自动核酸检测平台获国家药监局批准上市。上海之江生物 供图9月13日，澎湃新闻（www.thepaper.cn）记者从上海之江生物科技股份有限公司获悉这一消息。一台“小青耕”搭载了48个PCR扩增反应孔，可在2小时内完成48管样本的检测。如果搭配20混1方案，2小时内至少可完成960人份样本，单次检测通量1-48样本灵活设置，可有效提高门、急诊核酸筛查与复核效率，缓解人员不足的矛盾，也可快速提升医疗机构、疾控中心、机场口岸等的全自动核酸检测能力。同时，“小青耕”将核酸检测流程的各模块高度集成，占地面积小于0.4㎡，极大程度节约实验室紧张的空间，有限空间内最大程度提升核酸检测能力。同时搭载全封闭负压系统、紫外消杀和HEPA高效过滤系统，达到生物安全二级标准，全面保护检验人员操作安全。早在2022年4月，上海之江生物另一款核酸检测一体机“青耕一号”也已获批上市。“青耕一号”能连续运转24小时，可全自动化实现单管检测4500管，如果采用20混1方案，日检测量最高可达9万人次，且24小时连续工作仅需人工干预4次进行耗材移放，能快速提升上海尤其机场口岸、医疗机构等区域的大规模核酸检测能力。而与“青耕一号”相比，“小青耕”功能集约紧凑但全面，单台设备仅45Kg，可放置桌面，适用于各类实验室，包括发热门诊、急诊以及移动车载等空间环境相对有限的场所，快速灵活解决个性化需求。上海之江生物科技股份有限公司方面透露，当前，该公司还在开发更多核酸检测一体机可搭载检测项目，致力于减少病人检查多头跑、等待时间长的难题，为分子诊断领域作出更多贡献。
