Artificial CO_(2)removal from the atmosphere(also referred to as negative CO_(2)emissions)has been proposed as a potential means to counteract anthropogenic climate *** we use an Earth system model to examine the response of ocean acidification to idealized atmospheric CO_(2)removal *** our simulations,atmospheric CO_(2)is assumed to increase at a rate of 1%per year to four times its pre-industrial value and then decreases to the pre-industrial level at a rate of 0.5%,1%,2%per year,*** results show that the annual mean state of surface ocean carbonate chemistry fields including hydrogen ion concentration([H^(+)]),pH and aragonite saturation state respond quickly to removal of atmospheric CO_(2).However,the change of seasonal cycle in carbonate chemistry lags behind the decline in atmospheric CO_(2).When CO_(2)returns to the pre-industrial level,over some parts of the ocean,relative to the pre-industrial state,the seasonal amplitude of carbonate chemistry fields is substantially *** results also show that changes in deep ocean carbonate chemistry substantially lag behind atmospheric CO_(2)*** CO_(2)returns to its pre-industrial value,the whole-ocean acidity measured by[H^(+)]is 15%-18%larger than the pre-industrial level,depending on the rate of CO_(2)*** study demonstrates that even if atmospheric CO_(2)can be lowered in the future as a result of net negative CO_(2)emissions,the recovery of some aspects of ocean acidification would take decades to centuries,which would have important implications for the resilience of marine ecosystems.

Investigating the development toxicity of perfuorinated iodine alkanes(PFIs)is critical,given their estrogenic effects through binding with estrogen receptors(ERs).In the present study,two PFIs,including dodecafuoro-1,6-diiodohexane(PFHx DI)and tridecafuorohexyl iodide(PFHx I),with binding preference to ERαand ERβ,respectively,were selected to evaluate their effects on proliferation and differentiation of the mouse embryonic stem cells(m ESCs).The results revealed that,similar to E_(2),50μmol/L PFHx DI accelerated the cell proliferation of the m *** PFI stimulation at the exposure concentrations of 2–50μmol/L promoted the differentiation of the m ESCs as characterized by the upregulation of differentiation-related biomarkers(i.e.,Otx2 and Dnmt3β)and downregulation of pluripotency genes(i.e.,Oct4,Nanog,Sox2,Prdm14 and Rex1).Comparatively,PFHx DI exhibited higher induction effect on the differentiation of the m ESCs than did PFHx *** tests on ER signaling indicated that both PFI compounds induced exposure concentration-dependent expressions of ER signaling-related biomarkers(i.e.,ERα,ERβand Caveolin-1)in the m ESCs,and the downstream ER responsive genes(i.e.,c-fos,c-myc and c-jun)well responded to PFHx I *** role of ER in PFI-induced effects on the m ESCs was further validated by the antagonistic experiments using an ER inhibitor(ICI).The findings demonstrated that PFIs triggered ER signaling,and perturbed the differentiation program of the m ESCs,causing the potential health risk during early stage of development.

数字央行建设是央行业务高质量发展的前提,加快基层央行数字化转型步伐是数字央行建设中的重要一环。在人民银行IT“三集中”框架背景下,基层央行原则上不再建设信息系统,需要采用“脚本式”部署推动自身数字化转型。RPA以其流程化、自动化、智能化、跨系统的特点,成为基层央行数字化转型的首选。文章通过探索RPA在实际业务场景中的应用,为基层央行使用RPA开展数字化转型提供参考。

随着社会经济的不断发展,肥胖已经成为一种不可忽视的全球性流行疾病。除了受到遗传和饮食因素的影响外,肥胖的形成与发展也与环境中的化学物质暴露有关。研究发现一些具有内分泌干扰活性的化学物质可以影响机体脂代谢,如促进脂肪细胞形成、引起体内脂质累积增加等,这类物质被称为“环境致肥胖物质”。合成酚类化合物广泛用于工业生产和日常生活用品中,如塑料制品、消毒剂、杀虫剂和食品添加剂等,它们可通过饮食、饮水或皮肤接触等方式进入人体,是影响人体健康的潜在威胁。研究显示,合成酚类化合物具有内分泌干扰效应,可以影响脂肪生成过程、干扰脂代谢,具有致肥胖作用。由于这类物质都具有类似的苯酚结构,因此系统梳理这类化合物脂代谢干扰效应与致肥胖作用,有助于理解其构效关系与潜在健康风险。本文阐述了筛选环境致肥胖物质的3种常用研究模型,即体外分子互作研究模型、细胞成脂分化模型和动物脂代谢实验模型,并比较了各种模型的适用场景和优缺点。在此基础上,针对3种合成酚类化合物,即双酚A及其类似物、烷基酚和酚类抗氧化剂,结合其体外细胞与动物实验数据,对这些化合物的暴露现状和脂代谢干扰效应进行了分类描述,从它们对脂肪生成和代谢、肝组织脂代谢的影响等方面展开讨论。基于近年来脂代谢和致肥胖效应的相关研究,本文归纳总结了环境内分泌干扰物干扰脂代谢的内在毒理机制,主要包括核受体调控作用、炎症和氧化应激、肠道微环境、表观遗传和其他信号通路。最后本文指出了当前针对环境污染物,特别是新污染物,影响机体脂代谢引起肥胖效应研究中的不足,并对该领域研究进行了展望。
