Matrine induces apoptosis in hepatocellular carcinoma through Bid-mediated nuclear translocation of AIF [PDF]
, 2013 肝癌是一种常见的恶性肿瘤，它严重威胁着人类的健康。然而，由于肝癌本身所具有的生物学特性，使其成为目前尚缺乏有效治疗手段的疾病。苦参碱是从我国传统中药苦参的干燥根中提取出的一种生物碱活性成分，分子式为C15H24N2O，具有广泛的药理学作用。近年来的研究表明，苦参碱能在体内、外对多种肿瘤细胞起作用，诱导肿瘤细胞凋亡。然而，苦参碱诱导肿瘤细胞凋亡的作用机制还不明确。 本论文以人肝癌细胞系HepG2及裸鼠荷肝癌模型为研究对象，探讨苦参碱的抗肿瘤作用及原理。通过MTT法、PI染色法、流式细胞术 ...

Integrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant
