The patient number is relatively small, antiemetic medications were not administered using a fixed protocol, antiemetic levels were not measured, and the triplicate ECGs were performed too far apart to permit exposure-response modeling.
We review relevant literature suggesting in utero inflammation can lead to preterm labor, while insufficient development of the gut-blood brain barriers could permit exposure to potential neurotoxins.
Incremental policy acknowledges that SHS should be controlled because of its health consequences, but effectively gives priority to protecting workers and citizens in certain contexts while permitting exposure to continue in others.
This capsule permits exposure to an extensive diversity of peptides that can bind to various targets and be identified using peptide library techniques.
Longer liver stage development may positively influence the generation of pre-erythrocytic immunity by allowing time for protective immune responses to develop.> A key feature of CPS immunization is that it permits exposure to all Plasmodium life cycle stages in the vertebrate host, including parasitized erythrocytes.
The two required conditions for emergence were present: V. cholerae introduced into the population and breaches in the water, sanitation, and hygiene infrastructure permitting exposure to contaminated water.
Federal restrictions on the maximum permitted exposure to acrylamide, based on a largely clinical study of acrylamide neurotoxicity conducted ten years ago, may require a re-evaluation in the light of recent advances which have pinpointed the initial sites of nerve fiber degeneration.
We are concerned that changing health policies to permit higher exposures based on alleged benefits would be harmful, particularly to susceptible subgroups and individuals exposed to mixtures (Thayer et al. 2005).
A solid-phase application of this method offers an advantage in that it permits exposure of bacteria to sediment-bound contaminants (Kemble et al. 2000).
While in some samples, concentrations of Se and Mo were above the accepted limits, yet they were below the daily permitted exposure levels posing no health risk factor.
Given the dilemma surrounding human experimentation, in 1998 the Clinton administration placed a moratorium on the EPA reviewing human experiments for setting permitted exposure levels.
