Data are presented as mean ± SEM (n = 6/group). aaap value < 0.001; compared between naïve control which received a normal diet and vehicle and MetS+MCAO rats which received HCHF, MCAO, and vehicle. bbbp value < 0.001; compared between sham rats which received HCHF, sham operation, and vehicle and MetS+MCAO rats which received HCHF, MCAO, and vehicle. ∗p value < 0.05 and ∗∗∗p value < 0.001; compared to MetS+MCAO rats which received HCHF, MCAO, and vehicle.
