Four new or updated epidemiologic studies were presented at a meeting on the health effects of gasoline exposure held in Miami, Florida, November 5-8 , 1991
Children's health was the focus of almost 30 different sessions at the International Conference on Environmental Epidemiology and Exposure, held 2 6 September 2006 in Paris.
A strength of the present study was the use of a standard, well-tested protocol that enabled different ads to be compared on an equal footing, with advertising exposure held constant across participants.
As for investments, his advice is to "reduce equity exposure, hold gold — it's a quasi-currency".
In order to express the risk due to Cu exposure, holding other variables constant, we estimated the RR [95% confidence interval (CI)] due to an increase of Cu exposure and kept the no-exposure groups as the reference risk value.
Pregnancies with PCE exposure greater than or equal to the sample median had 2.38-times the risk of ending in stillbirth relative to those with no exposure, holding covariates constant (95% CI: 1.01, 5.59) (Table 5).
The ability to monitor changes in gene expression as a result of environmental exposure holds great promise in our understanding of the effect of environmental toxicants on human health.
Because males were not individually marked upon introduction to the exposure holding tanks (i.e., two males per tank), pre-exposure and post-exposure male color scores were independently averaged across both males within each exposure tank (Controlsolvent: n = 12 exposure tanks; BPA: n = 16 exposure tanks).
Using a two-phase cross-over design, marmosets (n = 16) were submitted to one trial for each stimulus, divided into four 5-min intervals: pre-exposure, exposure and post-exposure observations held 0 and 4 h later.
To further test if there was a significant effect of the UMTS exposure on arousal when order of exposure was held constant, separate 2 (condition: UMTS, sham) X 2 (group: sensitive, control) between-subjects ANOVAs were performed for each session (see Table 3 for mean, standard error, and F values).
