BACKGROUND A38-year-old man presented with a history of fish odor (since age 5) and unusual muscle fatigue with increased serum creatine kinase. Our aim was to identify the metabolic error in this new condition. METHODS We used 1H NMR spectroscopy to study serum and urine from the patient. RESULTS The concentration of N, N-dimethylglycine (DMG) was increased approximately 100-fold in the se...

ERETIC2 (Electronic Reference To access In vivo Concentrations 2) based on PULCON (Pulse Length-based Concentration determination) methodology is a quantitative NMR (qNMR) using an external standard. The performance of the PULCON method was assessed using maleic acid (MA). Quantification of the diarrhetic shellfish toxin and okadaic acid by PULCON was successfully consistent with that obtained ...
