To Ban or Not to Ban: The UK's Hamlet Moment With Farm Antibiotics
Politics &Policy, Volume 53, Issue 6, December 2025.ABSTRACT This article applies the Multiple Streams Framework (MSF) to examine post‐Brexit antimicrobial resistance (AMR) governance in UK agriculture, focusing on the contested regulation of prophylactic antibiotic use in farm animals. The study reveals how Brexit created a structural policy window, yet political and ideological dynamics rendered it ...

热化疗逆转人肝癌细胞系HepG2/ADM多药耐药性的实验研究
Zhongguo shiyan zhenduanxue, 2007 目的研究热化疗对多药耐药人肝癌细胞系HepG2/ADM耐药性的影响并探讨相关的机制。方法通过MTT法测定热化疗对多药耐药人肝癌细胞系HepG2/ADM耐药性影响;利用流式细胞仪检测细胞内ADM浓度变化。结果热化疗使多药耐药人肝癌细胞系HepG2/ADM耐药性降低;细胞内阿霉素浓度提高。结论热化疗具有逆转多药耐药人肝癌细胞系HepG2/ADM耐药性的作用,可能与细胞内阿霉素浓度提高有关。
