Furthermore, as depicted in Figure 8B, we observed a gradual decline in research interest in clusters #7 (mesenchymal stem cells), while sustained research interest remains for clusters #0 (chronic kidney disease), #1 (septic shock), #2 (acute kidney injury), #3 (renal inhury), #4 (macrophage activation syndrome), #5 (mice), #6 (oxidative stress), #8 (phenotype), and #9 (tnf alpha). This evidence concerns the gene TNF and septic shock.
