Time kinetics of PS-particles concentrations in maternal and fetal compartment using control- (continuous line, n = 5) or plasma medium (dashed line, n = 5). Each graph shows data obtained from different sampling ports: a maternal artery, b maternal vein, c fetal artery, and d fetal vein. Statistical analysis by using a linear mixed model was performed. Significant interaction effects (time, media) are displayed above distinct time points. Significant main effect (media) is indicated to the right of the graphs (b, d). Statistically significant differences are depicted as: *p < 0.05, **p < 0.01 and ***p < 0.001. Data are presented as mean ± SD
