以江苏省、浙江省、上海市农田为研究区,选用气候、地形、植被、土壤属性等自然环境协变量,及农业机械总动力、每公顷农用化肥施用量、农业总产值、农村用电量等农业活动变量,利用递归特征消除方法(RFE)对环境协变量进行筛选,基于筛选后的最优变量组合建立随机森林(RF)模型,进行表层土壤pH、有机碳、全氮、全磷、全钾、铵态氮、硝态氮、有效磷、速效钾、交换性钙、交换性镁11种主要土壤肥力属性的空间分布预测,并采用100次重复的十折交叉验证法进行验证。结果表明:①11个模型筛选出的环境协变量类型主要集中在气候、地形与植被变量,表征人类农业活动的变量在有机碳、全磷、全钾、铵态氮和有效磷预测中体现重要作用。②11个模型的决定系数(R^(2))在0.27~0.53,pH、速效钾、交换性镁和交换性钙的预测模型决定系数(R^(2))均在0.45以上。本研究表明人类活动变量对于土壤肥力预测具有重要意义,而递归特征消除−随机森林模型(RFE-RF)可以用于农田主要土壤肥力属性制图,为农业生产提供准确的土壤肥力属性空间分布信息。

Crimean-Congo hemorrhagic fever(CCHF)is a zoonotic disease caused by the CCHF virus(CCHFV),which is primarily transmitted by ticks(Lorenzo Juanes et al.2023).It is an emerging disease that occurs sporadically in Africa,Asia,and Europe,with a high morbidity and mortality rate,as high as 30%in humans(Ceylan et al.2013).CCHFV,belonging to genus Nairovirus,family Bunyaviridae,was first identified in the Congo in the 1960s.

miR-5100 promotes tumor growth in lung cancer by targeting Rab6

中国生物化学与分子生物学会第十一次会员代表大会暨2014年全国学术会议

作者： Gang Liu Ziying Lin Yahong Wang Jinfeng Tang haili huang 广东医学院附属医院临床医学研究中心

Chrysotile asbestos exposure is associated with excess mortality from pulmonary diseasessuch as lung cancer, mesothelioma, and asbestosis. Although multiple mechanisms bywhich chrysotile asbestos fibers induce pulmonary disease have been identified, the roleof apoptosis in human lung alveolar epithelial cells(AEC) has not been fully explored. Accumulatingevidence implicate AEC apoptosis as a crucial event in the development ofidiopathic pulmonary fibrosis(IPF) as well as asbestosis. The goal of this study was to determinewhether chrysotile asbestos induces mitochondria-regulated(intrinsic) AEC apoptosisand, if so, whether this occurs via activation of mitogen-activated protein kinases(MAPK). Using human A549 bronchoalveolar carcinoma-derived cells with alveolar epithelialtype II-like features, we show that chrysotile asbestos induces a dose/timedependentdecrease in cell viability, which is accompanied by the activation of the MAPKc-Jun N-terminal kinases(JNK), but not the MAPKs extracellular signal-regulated kinase(ERK)1/2 and p38. Chrysotile asbestos induces intrinsic AEC apoptosis as evidenced by theup-regulation of pro-apoptotic Bax and Bak along with activation of caspase-9, poly(ADPribose)polymerase(PARP), and cytochrome c release. Notably, SP600125, a specific JNKinhibitor, blocked chrysotile asbestos-induced JNK activation and apoptosis as assessed byboth caspase-9 cleavage and PARP activation. Our results demonstrate that chrysotile asbestosinduces intrinsic AEC apoptosis by a JNK-dependent mechanism and suggests apotential novel target for modulating chrysotile asbestos-related lung diseases.
