Phthalates are associated with a variety of health outcomes, but sources that may be targeted for exposure reduction messaging remain elusive. Diet is considered a significant exposure pathway for these compounds. Therefore, we sought to identify primary foods associated with increased exposure through a review of the food monitoring survey and(More)

The structure of supergiant shells, in particular of LMC 4, is hard to explain with stochastic self-propagating star formation. A series of supergiant structures lies along the outer edge of the LMC and form a sequence increasing clockwise in age. We have considered the rotation of the LMC and its motion through the halo of the Milky Way and propose that(More)
A detailed kinetic analysis of the distribution of cytoplasmic myosin during the capping of various lymphocytic surface molecules revealed two distinct capping mechanisms. (a) Some cell surface molecules, including immunoglobulin, Fc receptor, and thymus leukemia antigen, all cap spontaneously in a small fraction of lymphocytes during locomotion.(More)
BACKGROUND Endocrine-disrupting chemicals (EDCs) may be involved in the etiology of autism spectrum disorders, but identifying relevant chemicals within mixtures of EDCs is difficult. OBJECTIVE Our goal was to identify gestational EDC exposures associated with autistic behaviors. METHODS We measured the concentrations of 8 phthalate metabolites,(More)
OBJECTIVE The purpose of this study was to examine the association of tobacco smoke and environmental lead exposure with conduct disorder (CD). METHODS The National Health and Nutrition Examination Survey (NHANES) 2001-2004 is a nationally representative cross-sectional sample of the noninstitutionalized U.S. population. We examined the association of(More)
BACKGROUND Pyrethroid pesticides cause abnormalities in the dopamine system and produce an ADHD phenotype in animal models, with effects accentuated in males versus females. However, data regarding behavioral effects of pyrethroid exposure in children is limited. We examined the association between pyrethroid pesticide exposure and ADHD in a nationally(More)
BACKGROUND Exposure to phthalates, a class of endocrine disrupting chemicals, is ubiquitous. We examined the association of urinary phthalate metabolite concentrations during pregnancy with maternal blood pressure and risk of pregnancy-induced hypertensive diseases. METHODS We used data from the Health Outcomes and Measures of the Environment Study, a(More)
BACKGROUND Early-life exposure to bisphenol A (BPA) may increase childhood obesity risk, but few prospective epidemiological studies have investigated this relationship. OBJECTIVE We sought to determine whether early-life exposure to BPA was associated with increased body mass index (BMI) at 2-5 years of age in 297 mother-child pairs from Cincinnati, Ohio(More)
Detailed studies of steady-state ion fluxes in murine lymphocytes were used to examine for possible ionic changes generated by surface Ig, the antigen receptor of B lymphocytes. When bound by ligands, surface Ig triggered the mobilization and release of 45Ca2+ from the cell interior by a transmembrane process requiring crosslinking of the bound receptors.(More)
Capping of membrane Ig was studied in lymphocytes treated with agents that interfere with adenosine metabolism. Treatment of murine or human B cells with combinations of coformycin, an inhibitor of adenosine deaminase, homocysteine, and adenosine impaired Ig capping. Inhibition of capping was also produced by 3-deazaadenosine, a specific inhibitor of(More)
