Development of a mechanism for the rapid risk assessment of cross-border chemical health threats.

Background: Chemical incidents can result in harm to public health and the environment. Although most are localised and have little impact, some affect wide areas, a range of sectors and may lead to many casualties. A public health response to assess the risks and provide advice to authorities and the public is usually required.

Development of a new categorization system for pesticides exposure to support harmonized reporting between EU Member States.

Objectives: European legislation requires reporting from Member States on acute poisoning incidents involving pesticides. However, standard rules for data collection and reporting have not yet been set out. The new categorization system presented in this paper is aimed at enabling Member States to gather comparable data and provide standard reporting on pesticide poisoning exposures.

Targeting of SWI/SNF chromatin remodelling complexes to estrogen-responsive genes.

SWI/SNF complexes are ATP-dependent chromatin remodelling enzymes that have been implicated in the regulation of gene expression in yeast and higher eukaryotes. BRG1, a catalytic subunit in the mammalian SWI/SNF complex, is required for transcriptional activation by the estrogen receptor, but the mechanisms by which the complex is recruited to estrogen target genes are unknown. Here, we have identified an interaction between the estrogen receptor and BAF57, a subunit present only in mammalian SWI/SNF complexes, which is stimulated by estrogen and requires both a functional hormone-binding domain and the DNA-binding region of the receptor.
