From the authors: “Overall, [total conjugated bromotyrosine] provides a simple and specific noninvasive approach for monitoring eosinophil activation and oxidative stress and may serve as a useful biomarker for identification of patients who are suffering greater oxidative tissue remodeling.”

This study is highlighted as one of November’s “best of the best” as part of the American Physiological Society's APSselect program.
