Fig. 6From: Hepatotoxicity and the role of the gut-liver axis in rats after oral administration of titanium dioxide nanoparticlesEffect of TiO2 NPs on the content of LPS and SCFAs. a LPS concentrations in the serum and fecal samples increased significantly in the TiO2 NPs exposure groups compared with the control group. b SCFAs, including acetic acid (AA), propionic acid (PA), isobutyric acid (IBA), butyric acid (BA), isovaleric acid (IVA), and hexanoic acid (HA), did not change significantly after exposure to TiO2 NPs in the feces. Significant difference compared with the control group (∗ p < 0.05). LPS: lipopolysaccharides; SCFAs: short-chain fatty acidsBack to article page
