By far, the most common approach for estimating reference conditions is to quantify them at a set of sites relatively unexposed by human activity.
We conclude that this model approach creates isolated hyperglycemic fetal exposure while maintaining relatively unexposed control fetuses in the opposing uterine horn and that this approach is likely well-suited to study of other agents that may impact on fetal health.
Areas where both extensive and semi-intensive poultry production systems coexist were believed to be particularly at risk, while larger scale commercial and industrial poultry plants remained relatively unexposed (4, 5 ).
Dawn Approach the previous year was 124 and in recent times we have seen 126-rated champions like Frankel, New Approach and Dream Ahead, but 122 is a very satisfactory figure for such a relatively unexposed horse".
The eight-year-old, relatively unexposed as a chaser, gets into Saturday's £150,000 three-and-a-quarter mile contest low in the handicap and goes to the fray off the back of a sparkling piece of work on Tuesday morning.
Although UV radiation is generally considered to be the major aetiological agent, it was found that approximately 75% of the tumours occurred on the relatively unexposed body sites.
The cohort comprises 577 children born to women recruited at midpregnancy in two towns in Kosovo, Yugoslavia; one town is the site of a lead smelter, refinery, and battery plant and the other is 25 miles away and relatively unexposed.
In fact, rather than enhanced virulence being explained by the addition of virulence factors, virulent CA-MRSA may represent "cleanskin" S. aureus that has been relatively unexposed and unaffected by the selective pressures of antibiotics and the hospital environment (Uhlemann et al. 2013) and has therefore not acquired virulence tempering mutations.
If this information inspires life changes for some, it can seem to those people that anyone unexposed to the information is relatively blameless in contrast to those who are exposed but do not change.
A limitation of our study is, however, that the comparison group of women unexposed to IVF treatment was relatively small, and that a proportion of these women (40%), had used FDs (clomiphene) outside the IVF setting (as did 54% of women in the IVF group), thus restricting the power for comparisons with a truly unexposed reference group.
