The stability of extracted and prepared specimens was assessed by analysis of 2 controls enriched with MMA, MCA, and HCY at 5.
Recovery was evaluated by the analysis of DBSs spiked with MMA, MCA, and HCY at 2 concentrations (5 and 50 [micro]mol/L).
MS signal suppression and/or enhancement was evaluated by the post-column infusion of MMA, MCA, and HCY (13).
At the end of the treatment period, 3 animals from the control group had to be excluded because they exhibited spontaneously increased HCY >10 [micro]mol/L.
max] showed a highly significant negative correlation with plasma HCY (r = -0.
Accordingly, there was also a highly significant correlation between circulating HCY and BAr/TAr (Fig.
Concentrations of HCY in the CSF correlated to CSF-folate (r = -0.
Little is known about HCY transport and metabolism in human brain.
We observed a weak association between CSF and serum concentrations of HCY (r = 0.
We also adjusted the culture medium to 0, 10, 50, and 100 [micro]mol/L HCY (Sigma), cysteine (Sigma,), and glutathione (Sigma).
For each individual, we prepared 32 wells (8 wells for each HCY concentration).
PBMCs from 3 donors were cultured, as described before, in these wells (3 slices per donor and HCY concentration).
