Background: Phthalate exposure may increase the risk of asthma. Little is known about whether oxidative-stress related genes may alter this association. First, this motivated us to investigate whether genetic polymorphisms of the oxidative-stress related genes glutathione S-transferase Mu 1 (GSTM1), glutathione S-transferase pi 1 (GSTP1), superoxide dismutase 2 (SOD2), catalase (CAT), myelopero...

BACKGROUND Gestational phthalate and bisphenol A (BPA) exposure may increase the risk of adverse maternal/child health outcomes, but there are few data on the variability of urinary biomarkers before and during pregnancy. OBJECTIVE We characterized the variability of urinary phthalate metabolite and BPA concentrations before and during pregnancy and the ability of a single spot urine sample t...

Phthalates are ubiquitous endocrine-disrupting chemicals that are contaminants in food and contribute to significant dietary exposures. We examined associations between reported consumption of specific foods and beverages and first trimester urinary phthalate metabolite concentrations in 656 pregnant women within a multicenter cohort study, The Infant Development and Environment Study (TIDES), ...

Phthalate diesters, widely used in flexible plastics and consumer products, have become prevalent contaminants in the environment. Human exposure is ubiquitous and higher phthalate metabolite concentrations documented in patients using medications with phthalate-containing slow release capsules raises concerns for potential health effects. Furthermore, animal studies suggest that phthalate expo...

BACKGROUND Maternal hypothyroidism during pregnancy can cause adverse effects in the fetus. Scientific evidence has shown that probable thyroid-like function of some phthalates in vitro and in vivo, and phthalates exposure, can begin in utero. This study investigated the association between phthalate exposure and thyroid hormones in pregnant women. METHODS Serum and spot urine samples were co...

Phthalate exposure is widespread among pregnant women but whether it is related to fetal growth and birth weight remains to be determined. We examined whether first trimester prenatal phthalate exposure was associated with birth weight in a pregnancy cohort study. We recruited first trimester pregnant women from 2010-2012 from four centers and analyzed mother/infant dyads who had complete urina...

Exposure to phthalates is widespread because of their use in plastics, cosmetics, and other consumer products. Phthalate exposure has been associated with adverse respiratory outcomes in children. With urinary phthalate measures, we assessed the association between phthalate exposure and four pulmonary function parameters [forced vital capacity (FVC), forced expiratory volume at 1 sec (FEV1), p...

BACKGROUND Recent studies have identified associations between the concentration of phthalates in indoor dust and allergic symptoms in the airways, nose, and skin. OBJECTIVES Our goal was to investigate the associations between allergic symptoms in children and the concentration of phthalate esters in settled dust collected from children's homes in Sofia and Burgas, Bulgaria. METHODS Dust s...

objective(s) in recent years concerns have been raised regarding the incidence of male reproductive disorders from exposure to endocrine disruptors. so, chronic effects of di(2-ethylhexyl)phthalate were studied on histological and stereological structure of testis in adult wistar rats. materials and methods thirty two adult wistar rats were randomly divided in four equal experiment groups; oil ...

Phthalic acid esters may be used as plasticizers in food-packaging materials that have direct contact with food. Under normal conditions of use small amounts of the plasticizers would be expected to migrate into the food. The safe use of the phthalic acid esters under these conditions is based on available toxicity data, as well as regulations which, in general, specify the maximum extractable ...
