Researchers use metabolomic analysis to diagnose DM even after death, calling for the technique’s use in forensic analysis

Caption

A. Score and loading plots of PCA. 10 samples from the DM group (red) and 10 samples from the negative (Ng) group (green) are plotted based on 22 ions with statistical significance in the analysis targeting hydrophilic substances. The loading plot corresponds to the PCA score plot, with one plot representing a single ion. From this plot, it is possible to visually understand what the characteristic components are for the DM and Ng groups, respectively. B. Heat map analysis of metabolomics for hydrophilic substances. The row displays the ions, and the column represents the samples. Ions with significantly lower levels are displayed in blue, while ions with significantly higher levels are displayed in red. The brightness of each color corresponds to the magnitude of the difference when compared to the average value. The samples roughly form clusters of DM group (red) and Ng group (green).
