Autism spectrum disorders affect behaviors that emerge at ages when typically developing children become increasingly social and communicative, but many lines of evidence suggest that the underlying alterations in the brain occur long before the period when symptoms become obvious. Studies of the behavior of children in the first year of life demonstrate(More)
Data from 10 sites of the NICHD/NIDCD Collaborative Programs of Excellence in Autism were combined to study the distribution of head circumference and relationship to demographic and clinical variables. Three hundred thirty-eight probands with autism-spectrum disorder (ASD) including 208 probands with autism were studied along with 147 parents, 149(More)
BACKGROUND The HOXA1 gene plays a major role in brainstem and cranial morphogenesis. The G allele of the HOXA1 A218G polymorphism has been previously found associated with autism. METHODS We performed case-control and family-based association analyses, contrasting 127 autistic patients with 174 ethnically matched controls, and assessing for allelic(More)
Autism is a neurodevelopmental disorder characterized by an early onset of abnormal social, communicative, and repetitive behavior. Engrailed-2 (EN2) was identified as an autism candidate gene because its influence on cerebellar development in mice parallels neurodevelopmental abnormalities seen in individuals with autism. Studies investigating association(More)
OBJECTIVE To investigate the risk of vulvar vestibulitis syndrome (VVS) in the presence of specific genetic variants (polymorphisms) that affect chronic inflammation, pain and skin color. STUDY DESIGN For a retrospective, case-control study performed at a university-based ambulatory gynecologic service, 36 consecutive VVS cases and 69 consecutive(More)
BACKGROUND Valproic acid (VPA) exposure in utero has been associated with an increased risk of both neural tube defects and autism spectrum disorders (ASDs). The terata induced by VPA suggest interference with pattern formation. Retinoic acid produces similar terata and is known to act in part by increasing the expression of Hoxa1. We tested the hypotheses(More)
Para-Methylthiobenzamide (PMTB) produces injury to the liver and kidney. Toxicity is mediated via its biotransformation to a reactive S,S-dioxide metabolite. The objective of this study was to examine the role of hepatic metabolism in the production of PMTB-induced renal toxicity. Renal injury was assessed in partially hepatectomized and sham-operated rats(More)
High sucrose low copper diet induces fetal growth restriction in the three strains of the Cohen diabetic rats: an inbred copper deficient resistant (CDr), an inbred copper deficient sensitive (CDs that become diabetic on high sucrose low copper diet -HSD) and an outbred Wistar derived Sabra rats. Although those growth restricted fetuses also exhibit(More)
Fetal Growth Restriction (FGR) is a leading cause for long term morbidity. The Cohen diabetic sensitive rats (CDs), originating from Wistar, develop overt diabetes when fed high sucrose low copper diet (HSD) while the original outbred Sabra strain do not. HSD induced FGR and fetal oxidative stress, more prominent in the CDs, that was alleviated more(More)
