To determine the association between prenatal tobacco smoke exposure and neurological impairment at 10years of age among children born extremely preterm (<28weeks of gestation). The Extremely Low Gestational Age Newborn (ELGAN) Study, a prospective cohort. Ten-year follow-up of extremely preterm infants born at 14 US hospitals between 2002 and 2004. Prenatal tobacco smoke exposure was defined as a mother's report at enrolment of active (i.e. maternal) and passive smoking during pregnancy. Poisson regression with generalized estimating equations was used. Models adjusted for mother's age, race/ethnicity, education, insurance, pre-pregnancy body mass index, US region, multiple gestation and infant's sex; and in sensitivity analysis, gestational age at delivery and clinical subtype of preterm birth, given their classification as intermediate and non-confounding variables. Neurological impairment at 10years, epilepsy, cerebral palsy and cognitive impairment. Of 1200 ELGAN study survivors, 856 were al active tobacco smoke exposure was associated with an increased risk of epilepsy at 10 years of life.Serotonin N-acetyltransferase (SNAT) is the key rate-limiting enzyme in melatonin biosynthesis. It mediates melatonin biosynthesis in plants by using serotonin and 5-methoxytryptamine (5-MT), but little is known of its underlying mechanisms. Herein, we present a detailed reaction mechanism of a SNAT from Oryza sativa through combined structural and molecular dynamics (MD) analysis. We report the crystal structures of plant SNAT in the apo and binary/ternary complex forms with acetyl-CoA (AcCoA), serotonin, and 5-MT. OsSNAT exhibits a unique enzymatically active dimeric fold not found in the known structures of arylalkylamine N-acetyltransferase (AANAT) family. The key residues W188, D189, D226, N220, and Y233
