SL 2: Background 1 First of all, I’d like to touch on the background of this study. As you know well, persistent organic pollutants (POPs) representing polychlorinated dibenzo-p-dioxins, dibenzofurans, PCBs, and organochlorine insecticides are lipophilic stable contaminants. They have been detected in a wide range of environmental media and biota, and have been of great concern on their toxic e...
In vitro and animal studies report that some persistent organic pollutants (POPs) trigger the secretion of proinflammatory cytokines. Whether POP exposure is associated with a dysregulation of cytokine response remains to be investigated in humans. We studied the strength of association between plasma POP levels and circulating cytokines as immune activation markers. Plasma levels of fourteen P...
(ONFLICTING results have beeni reported with neonatal thymectomy in relation to several different chemical carcinogens given to animals by various routes. Some authors (Miller et al., 1963; Grant & Miller, 1965; Nomoto & Takeya, 1969) have shown that tumour induction could be increased in thymectomized animals when they were compared with a group that had had sham thymectomy. When thymectomized...
BACKGROUND There is emerging evidence that background exposure to persistent organic pollutants (POPs) are important in the development of conditions predisposing to diabetes as well as of type 2 diabetes itself. We recently reported that low dose POPs predicted incident type 2 diabetes in a nested case-control study. The current study examined if low dose POPs predicted future adiposity, dysli...
A field calibration study of low density polyethylene (LDPE) for measuring atmospheric concentrations of persistent organic pollutants (POPs) was performed in East Providence (RI), USA. LDPE samplers were collected after 3, 7, 10, 14, 17 and 21 days of exposure along with samples from a co-deployed high volume sampler. Uptake kinetics of POPs by LDPEs were confirmed both by using an uptake stud...
Continuous exposure to low doses of persistent organic pollutant (POPs), such as those occurring in the general population, might contribute burden type 2 diabetes mellitus (T2DM). However, evidences from longitudinal studies are scarce. We aimed explore associations accumulated POP with development T2DM by means 1) 16-year incidence disease, and 2) complementary cross-sectional analyses marker...
