Nevertheless, the presence of infectious prions in the saliva and blood of terminal CWD-infected deer [27] provide a possible mechanism for natural transmission among cervids and provide an exposure risk to humans and domestic livestock.
Hair typically grows 1 cm per month, thereby providing an exposure estimate of 1 6 months in our cohort.
To increase cost and information effectiveness, a cohort study should cover a wide range of exposures in order to provide an exposure contrast.
Additionally, the literature reviewed does not provide any clear tendency as to the effects of different concentrations of exposure: epidemiological studies using linear models did not provide an exposure effect threshold.
For each set of experiments, the choice of which coil was providing an exposure and which was the sham was computer-coded; decoding occurred when the study was complete.
This exposure provides an extensile exposure of the pelvis and femur.
Thus, repainting might have provided a sustained exposure since the gestational period or shortly following the birth.
This process provided a tentative exposure designation until more extensive assessments (described below) were completed.
Provided a sufficient exposure dose, several halogenated aromatic hydrocarbons can lead to increased urinary porphyrin excretion (Hogue and Brewster 1991).
For the photography activity, each participant was provided a 27-exposure disposable camera for taking still photographs and a one-page instruction sheet.
