In subjects GD009 and GD007, CMRO2 was measured again at 5-6 months post-triheptanoin oil consumption. The normal values for CMRO2 have been measured by us in a broad adult age-range and are gender-dependent (i.e., females exhibit higher CMRO2 than males). At ages 21 and 28 years, the normal male CMRO2 is 149 and 154 µmol/100g/min, respectively. The standard deviation none of our normal CMRO2 measurements exceeds 12.5 µmol/100g/min (HL et al, Age-related increase of resting metabolic rate in the human brain; submitted).
