DCF fluorescence from 60,000 microparticles (MPs). Values are means ± SE (n = 6) for MPs obtained from decompressed mice that were incubated with 10 μM Nox2ds (closed triangles) or scrambled sequence peptide (Deco-MPs, closed circle), or control mice (no decompression stress) incubated with scrambled sequence peptide (Control-MPs, open circles). For sake of clarity, control MPs incubated with Nox2ds are not shown, but slope was insignificantly different from decompressed MPs + Nox2ds (slope = 1.7 ± 2.1 fluorescence units/min).
