STUDY QUESTION Are urinary phthalate metabolites associated with reduced antral follicle growth among women in an infertility setting? SUMMARY ANSWER Higher urinary concentrations of di(2-ethylhexyl) phthalate (DEHP) metabolites were associated with significant decreases in antral follicle count (AFC) among women seeking infertility care. WHAT IS KNOWN ALREADY Experimental animal studies sh...

Questions about the safety of the plasticizer di(2-ethylhexyl) phthalate (DEHP), particularly in regards to exposure during medical procedures such as transfusions, have swirled for decades, but especially in the last several years, given growing concerns about endocrine disruption. In October 2005, an independent panel of experts convened by the National Toxicology Program Center for the Evalu...

Dr Trasande and his group in the article on phthalates conclude that urine phthalate concentrations (represented by urine di-2-ethylhexylphthalate [DEHP] concentrations) were associated with increased insulin resistance in this cross-sectional study of adolescents. Dr Trasande refers to this as an association and indicated that this study cannot rule out the possibility that insulin-resistant c...

The aim of the present research was to explore whether food emulsifier polysorbate 80 can enhance the absorption of di-(2-ethylhexyl) phthalate (DEHP) and its possible mechanism. We established the high-performance liquid chromatography (HPLC) method for detecting DEHP and its major metabolite, mono-ethylhexyl phthalate (MEHP) in rat plasma, and then examined the toxicokinetic and bioavailabili...

The industrial plasticizer di-(2-ethylhexyl)phthalate (DEHP) is used in manufacturing of a wide variety of polyvinyl chloride (PVC)-containing medical and consumer products. DEHP belongs to a class of chemicals known as peroxisome proliferators (PPs). PPs are a structurally diverse group of compounds that share many (but perhaps not all) biological effects and are characterized as non-genotoxic...

The tumor promotion stage of chemical carcinogenesis has been shown to exhibit a persistence of cellular effects during treatment and the reversibility of these changes upon cessation of treatment. Inhibition of gap-junctional intercellular communication and increased replicative DNA synthesis appear to be important in this process. The present study assessed the persistence and reversibility o...

The results of our studies on the extraction and disposition of three plasticizing substances which are extracted from poly(vinyl chloride) medical devices will be reported. The plasticizers are di-2-ethylhexyl phthalate (DEHP), di-2-ethylhexyl adipate (DEHA), and butylglycolyl butyl phthalate (BGBP). DEHP extraction will be described in greater detail, and the two other plasticizers, DEHA and ...

Incubation under controlled laboratory conditions were performed to assess the toxic effects of two plastic derived chemicals, bisphenol A (BPA) and di-(2-ethylhexyl) phthalate (DEHP), on growth, photosynthetic efficiency activity cosmopolitan diatom Chaetoceros decipiens-lorenzianus . Non-axenic cells exposed concentrations BPA DEHP (separately in mixture), mimicking observed contaminated mari...

Bisphenol A (BPA) and Diethylhexyl Phthalate (DEHP) are well-studied endocrine disrupting chemicals (EDCs), however, the effects of mixtures these EDCs not. To assess consequences prenatal exposure to a mixture EDCs, dams were orally administered either saline (control), BPA (5 μg/kg BW/day), high dose DEHP (HD-D; 7.5 mg/kg or combination with HD-D in experiment 1; saline, low-dose (LD-D; 5 BW/...

OBJECTIVE We previously demonstrated that exposure to polyvinyl chloride plastic medical devices containing di(2-ethylhexyl) phthalate (DEHP) was associated with higher urinary concentrations of several DEHP metabolites in 54 premature infants in two neonatal intensive care units than in the general population. For 42 of these infants, we evaluated urinary concentrations of several phenols, inc...
