Background: Bisphenol A (BPA), an estrogenic environmental contaminant is also known for oxidative stressinducing effect. The aim of this study was to investigate the effect of vitamin C as an antioxidant on the ovary tissue in adult rats treated with BPA. Materials and Methods: Adult female rats (200 ±20 g) were divided into 4 groups (n=6):control, bisphenol A (60μg/Kg/day) , vitamin C (150 mg...

Bisphenol A (BPA) is a known endocrine disruptor and one of the most serious environmental contaminants, often present at low levels in various water sources. Therefore, it is very important and necessary to develop a fast, cost-effective, sensitive, and selective method for on-site detection of BPA. Herein, we developed a portable, evanescent, wave fiber-optic aptasensor for rapid, on-site det...

Bisphenol A (BPA) is a widely studied typical endocrine-disrupting chemical, and one of the major new issues is the safe replacement of this commonly used compound. Bisphenol S (BPS) and bisphenol F (BPF) are already or are planned to be used as BPA alternatives. With the use of a culture system that we developed (fetal testis assay [FeTA]), we previously showed that 10 nmol/L BPA reduces basal...

Metformin, a Type II diabetic treatment drug, which inhibits transcription of gluconeogenesis genes, has recently been shown to lower the risk of some diabetes-related tumors, including breast cancer. Recently, "cancer stem cells" have been demonstrated to sustain the growth of tumors and are resistant to therapy. To test the hypothesis that metformin might be reducing the risk to breast cancer...

Transesterification mechanisms and rate in blends of polycarbonate (PC) and random liquid crystalline polyester copoly(oxybenzoate-p-terephthalate) at molar ratio 40/60 (P46) were studied through a five-component diad analysis and with 13C and 1H-13C nuclear magnetic resonance spectroscopy. It was found that the ester-ester interchange in the two polymers took place within 15 min when the blend...

The presence of endocrine-disrupting compounds, such as bisphenol A (BPA), in the environment can cause serious health problems. However, there are controversial opinions. This study investigated the reproductive, metabolic, oxidative and immunologic-disrupting effects of bisphenol A in male rabbits. Rabbits were divided into five groups. The first four rabbit groups were administered oral BPA ...

Dendrocalamus latiflorus Munro (ma bamboo) was liquefied in phenol or in polyethylene glycol/glycerol cosolvent, with H2SO4 as a catalyst. The liquefied bamboo was reacted with bisphenol-A and epichlorohydrin to prepare copolymer epoxy resins. The thermal properties of resins during and after curing were investigated by differential scanning calorimetry (DSC) and dynamic mechanical analysis (DM...

Considerable attention has been focused on environmental disruptors such as the xenoestrogen bisphenol A, which influences reproductive, developmental, and cognitive activities through its interaction with specific neuromediating systems in an estrogen-like fashion. In the present study, the effects of this xenoestrogen proved to be preferentially directed toward hypothalamic and extrahypothala...

OBJECTIVE The main objective of the study was to investigate the role of C-reactive protein on the relationship between Bisphenol A & Cardiovascular Disease, where the C-reactive protein has been taken as a moderating variable. METHODS Quantitative research design has been incorporated for evaluating the role of C-reactive protein. Similarly, non-parametric Spearman correlation test has been ...
