Mice were fed soy isoflavones (IF; 0, 126 or 504 mg aglycone equivalents of IF/kg diet) for 14-days prior to and during a 30-day exposure to LPS (1.33 μg/d). Biomechanical properties were determined using simulated compression strength testing with finite element analysis. Results are expressed as means ± standard error. Values for a given parameter that share the same superscript letter are not statistically different (P > 0.05) from each other.
