Brief Stresses and DNA Integrity: An Experimental Analysis
The goal of this study is to examine the impact of psychological stress on DNA integrity by
conducting an experiment under controlled conditions with healthy volunteers to directly test
the extent to which acute stress increases DNA damage, while simultaneously testing the
blocking effects of pre-treatment with propranolol, and exploring key hypothesized mediators
and moderators of the severity of the DNA damage.
