Recent Progress in the Development of Metal‐Based Radiosensitizations for Cancer Therapy: A Review
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Radiotherapy (RT) remains an indispensable means in cancer treatment; however, its therapeutic efficacy is often limited by tumor radioresistance and side effect of damage to healthy tissue. The advances in nanotechnology have propelled metal radiosensitizers to forefront of precision medicine.

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 ...

Reversal of multidrug resistance in human hepatocellular carcinoma cells by JNK [PDF]
, 2010 目的：多药耐药（multidrugresistance，MDR）细胞的存在是肝癌化疗失败的重要原因。有研究表明抗肿瘤药物能引起JNK信号传导系统的变化，提示通过调节JNK有可能逆转MDR。本课题应用抗癌药物阿霉素（ADM）诱导建立人肝癌多药耐药细胞HepG2/ADM，通过增高和降低肝癌多药耐药细胞HepG2/ADM中JNK的表达，检测多药耐药细胞的耐药性的变化，初步探讨JNK是否可做为逆转肝癌多药耐药细胞靶点的依据。 方法：采用药物浓度梯度递增诱导法诱导亲本细胞建立人肝癌多药耐药细胞系HepG2/ADM，

Polypeptide Micelle-based Theranostic Nanoplatform for Overcoming Cancer Multidrug Resistance [PDF]
, 2016 癌症是全球范围内导致人口死亡的一个重要原因，在各种癌症中，胃癌是一 种较为高发的癌症，特别是在发展中国家。在发展中国家中，胃癌是造成男性死 亡的第三大死因。由于胃癌容易产生潜在的淋巴结转移，单纯的手术切除通常不 是很有效。因而，临床治疗过程中，常在手术切除肿瘤病灶后，常利用化学疗法 对晚期或是已经发生转移的胃癌进行治疗。化学疗法在癌症的治疗中已经得到广 泛的应用，但化学治疗的同时，也产生了一个新的问题，即癌细胞在经过化疗药 物治疗后，出现了耐药性。为了解决癌细胞对化疗药物耐药的问题，临床常选用 ...
