CaMKII inhibition does not affect the development of active force . Mean values of active force measurements during 1-Hz pacing in LMS from the ENDO in the absence (n_control = 5 from five rats; n_cryoinjury = 4 from four rats) and presence of AIP (n_control = 4 from four rats; n_cryoinjury = 4 from four rats), and from the EPI in the absence (n_control = 7 from seven rats; n_cryoinjury = 3 from three rats) and presence of AIP (n_control = 3 from three rats; n_cryoinjury = 5 from five rats; comparison with two-way ANOVA with Bonferroni post-hoc testing).
