Fig. 1From: Developmental programming of DNA methylation and gene expression patterns is associated with extreme cardiovascular tolerance to anoxia in the common snapping turtleEffects of acute anoxia and reoxygenation on haemodynamic variables from N21 and H10 turtles. Turtles from the N21 (red circles, n = 6) and H10 (blue squares, n = 5) cohorts were subjected to 120 min of anoxia followed by 30 min reoxygenation. A Heart rate (\(f_{{\text{H}}}\)), B systemic blood flow (\(\dot{Q}_{{{\text{Sys}}}}\)), C pulmonary blood flow (\(\dot{Q}_{{{\text{Pul}}}}\)), D total blood flow (\(\dot{Q}_{{{\text{Tot}}}}\)), E systemic stroke volume (\(V_{{{\text{S}},{\text{Sys}}}}\)), F pulmonary stroke volume (\(V_{{{\text{S}},{\text{Pul}}}}\)), G shunt distribution (\(\dot{Q}_{{{\text{Shunt}}}}\)), H shunt ratio (\({{\dot{Q}_{{{\text{Pul}}}} } \mathord{\left/ {\vphantom {{\dot{Q}_{{{\text{Pul}}}} } {\dot{Q}_{{{\text{Sys}}}} }}} \right. \kern-\nulldelimiterspace} {\dot{Q}_{{{\text{Sys}}}} }}\)), I mean ventricular pressure (\(P_{{{\text{Vent}}}}\)), and J cardiac power output. Values are mean ± SEM, asterisks (*) indicate statistically significance difference between N21 and H10 groups, dollar ($) and psi (Ψ) symbols denote a significant difference between that data point and pre-anoxic levels (time zero) in the N21 and H10 groups, respectively (p ≤ 0.05)Back to article page
