Introduction: Bisphenol A is an aromatic compound that has many applications in various industries and is known as persistent pollutants. The aim of this study was to investigate bisphenol A removal by using activated carbon and shell eggs from aqueous solution by response surface experimental designs. Materials and Methods: In this study, activated carbon and eggshell were used as adsorbents....

هدف: هدف از این مطالعه بررسی نقش بازدارندگی ویتامین e  (ve) بر شاخص های اسپرماتوژنز رت ها به دنبال تیمار با bisphenol a بود. مواد و روش ها: رت های نر بالغ نژاد ویستار با میانگین وزنی10±231 گرم به‏طور تصادفی به 4 گروه (6=n): کنترل،  bpa (mg/kg/day250)، ve (mg/kg/day150) و bpa+ ve تقسیم شد. تیمار دهانی تا 56 روز و سه بار در هفته انجام گرفت. در پایان دوره تیمار، موش ها کشته شد و بیضه چپ آن ها توزی...

Bisphenol-S (BPS) is a new bisphenol-A substitute widely used in many plastic products. Bisphenol-A as a main member of bisphenol family has been known as an endocrine system disrupter chemical compound. Like other members of bisphenol family, there is public health concern about the toxic effects of BPS on reproductive system, thus, we examined BPS effects on in vitro fertilization (I...

Plasticizers with estrogenic activity, such as bisphenol A (BPA), have potential adverse health effects in humans. Due to mounting evidence of these health effects, BPA is being phased out and replaced by other bisphenol variants in "BPA-free" products. We have compared estrogenic activity of BPA with 6 bisphenol analogues [bisphenol S (BPS); bisphenol F (BPF); bisphenol AP (BPAP); bisphenol AF...

Introdution: Bisphenol A (BPA) as an environmental pollutant has estrogenic effects and can induce oxidative stress in the testis tissue. The aim of the present study was to investigate the role of vitamin E (Vit E), as a strong antioxidant, on the adverse effect of BPA on adult rat testis tissue. Methods: Male rats (220±15g) were divided into 4 groups (n=6/each): control, Bisphenol A (...

Bisphenol A, an environmental estrogen, can be leached from plastic tableware and from the coating of food and drink cans, orally exposing human beings to the compound. The present study focuses on the absorption and metabolism of bisphenol A in the rat intestine, as elucidated experimentally by segmented everted intestine. One hour after the application of 2 micromol of bisphenol A to the muco...

Phthalates and bisphenol A are environmental endocrine-disrupting chemicals used widely in common consumer products. There is increasing concern about human exposure to phthalates and bisphenol A due to the potential adverse effects related to the anti-androgenic activity of phthalates and estrogenic activity of bisphenol A. In assessing environmental exposure to phthalates and bisphenol A, it ...

Exposure measurement data from several developed countries indicate that human beings are widely exposed to low levels of the synthetic xenoestrogen, bisphenol A. We reported previously that bisphenol A, even at doses below the reference safe daily limit for human exposure, recommended by the U.S. Environmental Protection Agency, impairs the synaptogenic response to 17beta-estradiol in the hipp...

Background and purpose: Bisphenol A is a synthetic xenoestrogen that is used in large amount to produce polymers (polycarbonates, epoxy resins). It easily cross the blood-brain barrier and is reported to influence the central nervous system especially neurogenesis and synaptic transmission. In this research the effects of chronic administration of bisphenol A on spatial learning and memory in a...

Glycosylation of bisphenol A, which is an endocrine disrupting chemical, was investigated using immobilized marine microalga and plant cells from the viewpoint of bioremediation of bisphenol A. Immobilized marine microalga of Amphidinium crassum glucosylated bisphenol A to the corresponding glucoside. On the other hand, bisphenol A was glycosylated to its glucoside, diglycoside, gentiobioside, ...
