Assessment of periportal fibrosis in Schistosomiasis mansoni patients by proton nuclear magnetic resonance-based metabonomics models

Figure 1 Typical ¹H-nuclear magnetic resonance spectrum (400 MHz, D₂O, presaturation-Carr-Purcell-Meiboom-Gill) of serum from a patient with Schistosomiasis mansoni, Pernambuco, Brazil, 2020. Integration areas under the signal are associated with the concentration of metabolites weighted by the number of hydrogen nuclei in each chemical environment. Some assignments are presented in the spectrum.
