^aThe variables are changes in the concentrations in blood or plasma between two times W0 and W3 calculated as concentrations at W3 minus concentrations at W0 for plasma metabolites like AA (1-methylhistidine or 1-MH, glutamine or GLN, isoleucine or ILE, tryptophan or TRP and tyrosine or TYR), free fatty acids or FFA, and urea or UREA, plasma indicators of oxidative status (Biological Antioxidant Potential or BAP, Diacron reactive oxygen metabolites or dROM expressed in), acute phase protein (haptoglobin or HAPTO) and blood cells (neutrophil granulocytes (GRAN), monocytes (MONO) and white blood cells (WBC))
^bCarrU = “Carratelli Units”, where 1 CARRU is equivalent to the oxidizing power of 0.08 mg H₂O₂/dL
