Exposure to disinfection by-products（DBP） such as trihalomethanes（THM） in swimming pools has been linked to adverse health effects in humans, but their biological mechanisms are unclear. We evaluated short-term changes in blood gene expression of adult recreational swimmers after swimming in a chlorinated pool. Volunteers swam 40 min in an indoor chlorinated pool. Blood samples were drawn and four THM（chloroform,bromodichloromethane, dibromochloromethane and bromoform） were measured in exhaled breath before and after swimming. Intensity of physical activity was measured as metabolic equivalents（METs）. Gene expression in whole blood m RNA was evaluated using Illumina Human HT-12v3 Expression-Bead Chip. Linear mixed models were used to evaluate the relationship between gene expression changes and THM exposure. Thirty-seven before-after pairs were analyzed. The median increase from baseline to after swimming were： 0.7 to 2.3 for MET, and 1.4 to 7.1 μg/m^3 for exhaled total THM（sum of the four THM）.Exhaled THM increased on average 0.94 μg/m^3 per 1 MET. While 1643 probes were differentially expressed post-exposure. Of them, 189 were also associated with exhaled levels of individual/total THM or MET after False Discovery Rate. The observed associations with the exhaled THM were low to moderate（Log-fold change range：-0.17 to 0.15）. In conclusion, we identified short-term gene expression changes associated with swimming in a pool that were minor in magnitude and their biological meaning was unspecific. The high collinearity between exhaled THM levels and intensity of physical activity precluded mutually adjusted models with both covariates. These exploratory results should be validated in future studies.

[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。

Gone with the wind： Seasonal trends in foraging movement directions for a central-place forager

引用

Current Zoology 2014年第5期60卷 604-615页

Lesser kestrels Falco naumanni are migratory central-place foragers that breed in dynamic arable landscapes. After arriving from migration, kestrels have no knowledge of the distribution of crops, and consequently prey, around their colony. The energy demand of pairs increases as breeding season progresses, but at the same time prey abundance, and their knowledge on prey distribution, also increases. Wind can have a strong influence on flight cost and kestrels should try to reduce energy expendi- ture when possible. When prey abundance is low, kestrels have little knowledge of prey distribution, and pairs have no chicks, they could reduce foraging flight cost by leaving the colony with tailwinds. When prey is abundant, knowledge on prey distribu- tion has increased, and chick demand is high, kestrels should fly to the most favorable foraging patches. We analyzed foraging trips directions in a lesser kestrel colony along the breeding season and in relation to wind speed and direction. We recorded 664 foraging trips from 19 individuals using GPS-dataloggers. We found that outward flights direction changed from uniform to a concentrated distribution along the season, as prey abundance and individual experience increased. We also found a temporal trend in the angular difference between outward flights and wind directions, with low values early in the season and then increa- sing as expected, but again low values at the end, contrary to expectation. Results suggest changes in kestrels foraging strategy along the season in relation to wind. Kestrels depart more with tailwinds in exploratory flights early in the season, while there is a spurious coincidence in direction to preferred foraging patches and dominant wind direction at the end [Current Zoology 60 （5）： 604-615, 2014].
