A Beta-hydroxybutyric acid (BHBA) increased Ca-dependent fluorescence (P < 0.01) whereas NA-1 and NA-5 reduced Ca-dependent fluorescence in the presence of BHBA (P < 0.01). B 10 and 100 μmol/L niacin increased Ca-dependent fluorescence (P < 0.01). NA-1 and NA-5 reduced calcium fluorescence in the presence of 100 μmol/L niacin (P ≤ 0.01)
