Fig. 5From: Metabonomics profile analysis in inflammation-induced preterm birth and the potential role of metabolites in regulating premature cervical ripeningIntensity of significantly differential expressed metabolites between CTL and PTB groups. A-B Phosphatidylethanolamine and phosphatidylcholine were increased in PTB groups. C Amino acids were enriched in the CTL group. D-G. The PTB group had higher levels of organic sulfonic acids, carnitines, glycerophospholipids, and imidazopyrimidines (*p < 0.05, ** p < 0.01, and *** p < 0.001)Back to article page
