Objective: Recent studies have provided insights into the gut microbiota in autism spectrum disorder (ASD); however, these studies were restricted owing to limited sampling at the unitary stage of childhood. Herein, we aimed to reveal developmental characteristics of gut microbiota in a large cohort of subjects with ASD combined with interindividual factors impacting gut microbiota.
Design: A large cohort of 773 subjects with ASD (aged 16 months to 19 years), 429 neurotypical (NT) development subjects (aged 11 months to 15 years) were emolyed to determine the dynamics change of gut microbiota across different ages using 16S rRNA sequencing.
Background: There has been significant research on the genetic and environmental factors of congenital heart defects (CHDs), but few causes of teratogenicity, especially teratogenic mechanisms, can be clearly identified. Metabolomics has a potential advantage in researching the relationship between external factors and CHD.
Objective: To find and identify the urinary potential biomarkers of pregnancy (including in the second and third trimesters) for fetuses with CHD based on modified gas chromatograph-mass spectrometer (GC-MS), which could reveal the possibility of high-risk factors for CHD and lay the foundation for early intervention, treatment, and prevention.
Background: Eukaryotic translation initiation factor 4-gamma 1 (EIF4G1) gene mutations have recently been reported in autosomal dominant, late-onset Parkinson's disease (LOPD). We carried out genetic analysis to determine the prevalence of EIF4G1 variants in an ethnic Chinese population and to better understand the association between EIF4G1 and PD.
Methods: We conducted a comprehensive genetic analysis of EIF4G1 in a cohort of 29 probands of autosomal dominant, LOPD families.
