The effect of maternal high-fat diet and variable stress on plasma corticosterone concentration (a) and adrenal glands weight (b). On days 1 and 14 of the stress induction period, plasma concentrations of corticosterone were measured and the weight of the adrenal glands was determined 24 h after the last stress exposure. Each column denotes mean ± SEM (n = 8 per group); NC: Normal diet Control, NS: Normal diet Stress, HFC: High-fat diet Control, HFS: High-fat diet Stress; ^** P < 0.01, ^*** P < 0.001 vs. NC, ^$ P < 0.05, ^$$$ P < 0.001 vs. HFC, ^† P < 0.05, ^††† P < 0.001 vs. NS, ^ωω P < 0.01, ^ωωω P < 0.001 vs. day 1 of the same group
