[背景]产前暴露于双酚A（BPA）及邻苯二甲酸酯会影响胎儿发育；然而该类研究很少，且得出的结果不一致。[目的]对一个西班牙出生队列中488对母婴进行研究，评估产前暴露于BPA及邻苯二甲酸酯是否与胎儿发育相关。[方法]检测第一和第三孕期两次尿液样本中BPA及8种邻苯二甲酸酯[4种邻苯二甲酸二（2-乙基己基）酯代谢物（DEHPm），邻苯二甲酸单卞酯（MBzP）以及3种低分子量邻苯二甲酸酯代谢物（LMWPm）]。另外，估计股骨长度（FL）、头围（HC）、腹围（AC）、双顶径（BPD）的生长曲线，估计孕期（12—20周，20～34周）的胎儿体重，并测量出生体重、出生长度、出生头围以及胎盘重量。[结果]总体上，结果并不支持孕期暴露于BPA或DEHPm与胎儿发育参数相关。产前MBzP暴露与20～34孕周的FL呈正相关，MBzP浓度每增加一倍，平均FL增加3．7％（95％CI：0．75，6．63％）。MBzP与男婴出生体重呈正相关（48g；95％CI：6，90），但在女婴中没有相关性（-27g；95％CI：-79，25）（交互作用P=0．04）。LMWPm邻苯二甲酸单丁酯（MnBP）与12—20孕周的HC呈负相关[平均HC降低了4．88％（95％CI：-8．36，-1．36％）]。[结论]本研究首次将暴露生物标志重复测量值与胎儿期多种发育参数相结合，发现暴露于BPA或邻苯二甲酸酯与胎儿发育不相关。邻苯二甲酸酯代谢物MBzP与MnBP与部分胎儿发育参数相关，但这些结果还需要重复验证。

Atmospheric ammonia(NH_(3)) is a chemically active trace gas that plays an important role in the atmospheric environment and climate change. Satellite remote sensing is a powerful technique to monitor NH_(3) concentration based on the absorption lines of NH_(3) in the thermal infrared region. In this study, we establish a retrieval algorithm to derive the NH_(3)column from the Hyperspectral Infrared Atmospheric Sounder(HIRAS) onboard the Chinese Feng Yun(FY)-3D satellite and present the first atmospheric NH_(3) column global map observed by the HIRAS instrument. The HIRAS observations can well capture NH_(3) hotspots around the world, e.g., India, West Africa, and East China, where large NH_(3) emissions exist. The HIRAS NH_(3) columns are also compared to the space-based Infrared Atmospheric Sounding Interferometer(IASI)measurements, and we find that the two instruments observe a consistent NH_(3) global distribution, with correlation coefficient(R) values of 0.28–0.73. Finally, some remaining issues about the HIRAS NH_(3) retrieval are discussed.

This study aimed to discriminate ten Cameroonian cocoa hybrids according to their total fat, fatty acid composition, tocopherol and tocotrienol profiles. Six cocoa clones from the gene banks of the Cameroon Cocoa Development Corporation were used to create hybrids. The determination of fatty acid composition was carried out by using a gas chromatography (GC) apparatus coupled by a flame ion detector (FID). Tocopherol and tocotrienol analysis was performed by upper high-performance liquid chromatography (UHPLC). Information on the impact of the genotype on the cocoa fat composition was provided. The major fatty acids (FA) in fermented samples are stearic (34.57%), palmitic (26.13%), oleic (34.13%) and linoleic (3.16%) acids. (35.05% to 35.6%). SCA12 × ICS40, SCA12 × SNK13, SNK13 × T79/501 have the least hard cocoa butters. Tocopherols analysis showed a predominance of γ-tocopherols (94.64 ± 1.51 to 292.16 ± 3.17 µg∙g−1), whereas only a small amount of β and δ-tocopherol (from 0.46 to 2.78 µg∙g−1 and 0.12 to 5.82 respectively) was observed. No γ-tocotrienol was found in fermented samples. A differentiation in terms of total fat and tocopherol content was observed amongst hybrids with the same mother-clone, suggesting an impact of pollen on these compounds.

[背景]人类在生命早期的发育期间可能特别容易受到环境暴露的影响。有关这一主题的人体研究一般集中在单一暴露与健康效应之间的关系。而"暴露组"的概念涵盖了从受孕开始的的全部暴露,完善了基因组。[目的]人类生命早期暴露组(HELIX)项目是一个新的合作研究项目,目的是为了采用新的暴露评估和生物标志分析方法来描述生命早期多种环境因素的暴露,并将这些与生物标志组学和儿童健康结局相关联,从而刻画"生命早期暴露组"。本文描述了该项目的总体设计。[方法]HELIX将利用欧洲现有的6个出生队列研究来估计产前、产后暴露的一系列化学和物理暴露。建立全部队列中总共32 000对母亲和儿童的暴露模型,并在一个包含1 200对母亲和儿童的子队列中测量生物标志。嵌套重复采样的定组研究(n=150)将收集生物标志的变化数据,利用智能手机来评估流动性和体力活动,并监测个体暴露。采用组学技术确定与暴露相关的分子学特征(代谢组、蛋白质组、转录组和表观基因组)。对于多次暴露,采用统计方法估计胎儿和儿童的成长、肥胖、神经发育和呼吸系统结局中的暴露-效应关系。项目还将进行一项健康效应评估测试,以评价组合暴露的风险和收益。[结论]HELIX是描述欧洲人群生命早期暴露组并解开它与组学标志物和儿童健康之间关联的首次尝试之一。作为对暴露组学这一概念的验证,该项目向生命过程中暴露组迈出了重要的第一步。
