Figure 6. RMF improved lifespan in C. elegans. (A) Head-swing frequency. (B) Body-bend frequency. (C) The four levels of locomotivity. Motor ability assays were performed on day 6, 10, and 14. (D) Pharyngeal-pumping frequency (20 s). Different letters indicate a significant difference among groups (P < 0.05). All analyses were based on the data from three independent experiments.
