Bisphenol A (BPA), a well-known endocrine disruptor, is metabolized and eliminated rapidly from the body in adult animals. However, many authors have reported that perinatal BPA exposure alters development of the brain, reproductive system and behavior in the next generation. Recently, BPA substitutes, especially bisphenol F (BPF), have been used because of concerns about the influence of BPA o...

Objective(s): Bisphenol A (BPA) as a synthetic compound is applied in many plastic industries. BPA has been reported to have endocrine-disrupting feature with cytotoxic effects. The study aimed to evaluate the efficiency of Naringin against testicular toxicity induced by BPA in adult rats.Materials and Methods: The animals were assigned into six groups of control, BPA-treated (50 mg/kg), BPA+Na...

This work describes some results of identification and determination of bisphenol A (BPA) in powdered milk by applying the gas chromatography. To determine BPA contents in the milk and to reduce the matrix interference associated with the constituents of the powdered milk, we performed the following activities. First, we ultra-centrifuged the dissolved milk solutions. Next, we preconcentrated t...

Royal jelly is known as a functional food containing many useful minerals. In this study, we found an anti-environmental estrogen activity of royal jelly. Bisphenol A (BPA) is an environmental estrogen that stimulates proliferation of human breast cancer MCF-7 cells. Royal jelly inhibited the growth-promoting effect of BPA on MCF-7 cells, even though it did not affect the proliferation of cells...

Bisphenol A (BPA) is an endocrine disruptor which can mimic estrogen and has been shown to cause negative health effects in animal studies. The aim of this work was to study the protective effect of chitosan against BPA. Forty male albino rats were randomly divided into four equal groups. Group I, animals served as control. Group II, animals were injected by bisphenol A, intra-peritoneal, at a ...

We investigated the interaction of bisphenol A (BPA, an estrogenic environmental contaminant used in the manufacture of plastics) with the estrogen receptor alpha (ERalpha) transfected into the human HepG2 hepatoma cell line and expanded the study in vivo to examine the effect of BPA on the immature rat uterus. Bisphenol A was 26-fold less potent in activating ER-WT and was a partial agonist wi...

Sub-lethal toxic effects of Bisphenol A on Caenorhabditis elegans: the role of stress resistance genes in BPA-induced growth inhibition by Zailene Flood July, 2014 Director: Xiaoping Pan DEPARTMENT OF BIOLOGY Endocrine disrupting chemicals (EDCs) have become of concern for a variety of health issues. Bisphenol-A (BPA) is a widely studied EDC and has been characterized by its estrogen-like effec...

A reliable and sensitive method for simultaneous determination of bisphenol A (BPA) and bisphenol F (BPF) in canned food by gas chromatography-mass spectrometry (GC/MS) is described after extraction and pre-concentration by a new solid-phase microextraction (SPME) adsorbent. The potential of single-walled carbon nanotubes (SWCNTs) as SPME adsorbent for the pre-concentration of environmental con...

Bisphenol A (BPA) is a synthetic unit of polycarbonate polymers and epoxy resins, the types of plastics that could be found in essentially every human population and incorporated into almost every aspect of the modern human society. BPA polymers appear in a wide range of products, from liquid storages (plastic bottles, can and glass linings, water pipes and tanks) and food storages (plastics wr...
