Fig. 9From: Pregnancy exposure of titanium dioxide nanoparticles causes intestinal dysbiosis and neurobehavioral impairments that are not significant postnatally but emerge in adulthood of offspringPregnancy exposure to TiO2NPs did not affect the α-diversity indices at PD10, PD21 and PD49. After 16S rRNA sequencing, the richness and evenness of gut microbiota were evaluated by α-diversity indices at postnatal day (PD) 10, 21 and 49. A Effects of TiO2NPs on the Ace index. B Effects of TiO2NPs on the Chao index. C Effects of TiO2NPs on the Simpson index. D Effects of TiO2NPs on the Shannon index. E Effects of TiO2NPs on the Coverage index. Data were presented as mean ± S.E.M. Statistical analysis was performed by using repeated-measure ANOVA or independent student t test or Mann–Whitney U testBack to article page
