The Threshold of Toxicological Concern (TTC) concept for chemical safety assessment has encountered significant development over the last forty years.The TTC has been used in the risk assessment of chemicals to which humans are exposed at very low levels and was first used to asses chemicals migrating from food contact materials then gradually has been applied to a broad range of safety assessment including food and feed additives, genotoxic impurities in pharmaceutical products, cosmetic ingredients, household products, airborne substances, organic substances in the aquatic environment, plant protection product metabolites and combined exposures.

OBJECTIVE To explore the potential anti-cancer function and the pathway of Varacin-1 (VCA-1), which is an analog of varacin C, an agent known to induce DNA damage.METHODS VCA1 was synthesized by the c
Chrysin(5,7-dihydroxyflavone) exists widely in plants, honey and propolis.The anticancer property of chrysin has been demonstrated though the molecular mechanism is not clear.In this study,we found th
目的 探讨自吞噬在电离辐射之后细胞命运决定中的作用及其分子机制。方法 采用慢病毒感染的方法构建稳定敲低p53及对照A549细胞系,用血清饥饿诱导细胞自吞噬,3-MA抑制Beclin 1/Vps34介导的自吞噬,然后用γ射线照射细胞。采用流式细胞检测细胞周期的分布及细胞凋亡率。采用双荧光素酶报告系统检测目的基因的转录活性。结果 p53抑制自吞噬效应蛋白p62/SQSTM1在DNA放射损伤情况下的转录
Environmental and chemical carcinogens have been shown to act as both initiators and promoters of cancer.In the present study, we attempted to reveal critical pathways in chemical carcinogenesis that
环境或内源的化学物质或物理过程会损伤DNA.研究聚合酶如何处理这些DNA损伤可以揭示DNA复制错配、错位、突变、细胞死亡、老化和癌症等过程的分子机理,为DNA损伤引起的疾病的治疗提供重要参考依据.酒精、烟、烧烤、农药或其它烷基化剂均可形成N2-烷基嘌呤而改变了DNA的分子结构,然而这些DNA损伤如何影响DNA复制的机制并不清楚,其中的重点和难点是这类损伤是否、以及如何导致DNA复制的错配或中断,这
全球化学品统一分类和标签制度(GHS)的实施旨在减少不同国家地区之间对化学品分类和标签的差异,在国际范围内统一对化学品危害特征的认识,从而提高化学品防护,降低国际贸易成本.化学品测试方法是实施GHS制度过程中重要的技术支撑.GHS本身并未提出化学品的试验要求甚至不鼓励进行不必要的动物实验,而是通过证据权重,分析来自人类和动物的数据,并结合专家判断对化学品进行分类和标签.化学品测试方法作为GHS分类
《新化学物质申报登记指南》中,对固体物质急性吸入毒性豁免的要求为:物质的粒径分布中,可吸入部分<1%(重量百分比),且使用时产生的浮质、微粒或者液滴MMAD(质量Mass median aerodynamic diameter》 >100 μm.本文总结了粒径测试的相关方法,并给出了不同种类的固体物质进行粒径测定的建议.满足《新化学物质申报登记指南》中,对固体物质急性吸入毒性豁免的要求为:物质的粒
为研究经济学研究对毒物管理与立法的影响,本文回顾了20世纪90年代以来,一些涉及毒物和毒性事件有关的经济学研究对毒物管理与立法产生的积极影响。并就简述了环境污染对经济供需关系的影响、切尔诺贝利核事故带来的经济学影响、烟草经济学研究为控烟决策提供依据。以英国伦敦烟雾事件、"反应停"灾难、日本水俣汞污染事件、中国西部毒草灾害、"瘦肉精"中毒事件、毒奶粉事件等重大毒性事件的经济学研究为例,分述了这些毒性
本研究通过对辽河表层沉积物的重金属污染状况调查,对比分析丰水期、枯水期6种重金属(Cr,Ba,Ni,Cu,Zn和Pb)总量,评价了辽河水系沉积物中的重金属含量及污染程度,并利用统计分析的方法进行了污染来源分析,以期为综合治理辽河流域重金属污染提供基础数据.采用ICP-MS方法测定了辽河流域19个采样点位枯水期以及丰水期表层沉积物中6种重金属(Cr,Ba,Ni,Cu,Zn和Pb)的含量.用地累计指数
Progress in the use of non-testing methods in chemical risk assessment has accelerated in recent years as global chemical legislations have been updated to highlight the principles of animal welfare a
