The authors therefore suggest that targeting the PGE2 receptor EP1 might be a viable approach to treating hypertension.

01-14-2008 · EurekAlert!
Recent work led by University of Iowa neuroscientist Natalie Denburg, PhD, suggests that for a significant number of older adults, measurable neuropsychological deficits do seem to lead to poor decision-making and an increased vulnerability to fraud. The findings also suggest that these individuals may experience disproportionate aging of a brain region critical for decision-making.
