Isolated myocyte function from mice exposed to filtered air (FA) or particulate matter (PM) for 9 months in the OASIS-1 trailer. A, Representative shortening of FA and PM myocyte contraction. B, Percent peak shortening (%PS) normalized to sarcomere length (SL). C, Time-to-90% peak shortening (TPS90), and D, time-to-90% relengthening (TR90). n=20 to 30 myocytes from 3 to 4 mice per group. Data are expressed as mean±SEM and analyzed using a Student t test. P<0.05 was considered statistically significant.
