There were no significant group differences in any of the other behavioral categories, i.e., self-stimulation, environmental exploration, and vigilance (data not shown), and there were no manifestations of physical distress or weight change.
With the reduction of Pb in fuel and soldered cans as well as increased awareness and vigilance, acute environmental Pb exposure has decreased dramatically (Pirkle et al. 1998).
In our experience, close vigilance of environmental contamination and enforcement of infection prevention and antibiotic policies proved efficient to control nosocomial transmission and reduce the rates of VRE-BSI in subsequent years.
Much attention has been paid to environmental variables that influence antipredator vigilance.
However, the presence of other inhibitors in the environment increases the need for vigilance against additional environmental contaminants, and California law requires consideration of the effects of multiple chemicals that act similarly.
We did not include, unless a relevant part of the mission was research, organisations with functions of environmental protection, radiation protection, pharmaco-vigilance or veterinary services/animal health.
The vigilance of cells to environmental change, the alacrity of the transcriptional response, the short half-life of cellular mRNA and the genome-scale nature of the investigation collectively explain the power of this method.
The persistence of PBDEs raises our vigilance for potential adverse environmental and human health consequences.
"Without standards, there has to be a constant state of vigilance by the buyer, property manager, environmental consultants and the industry".
In these cases, we carefully controlled that not only the stimulation parameters, but also other environmental and subjective conditions (such as daytime, room brightness, subject's vigilance level) were exactly the same.
