The scratch resistance of coatings used on two highly visible automotive applications (automotive bodies and window glazings) were examined and reviewed. Types of damage (scratch vs. mar), the impact on customers, and the causes of scratch events were investigated. Different exterior clearcoat technologies, including UV curable and self-healing formulations were reviewed, including results from...

In this study, the degradation of bisphenol A in aqueous suspension by interaction of photocatalytic oxidation and ferrate(VI) oxidation was investigated under different conditions. The results indicate that the formation of Fe(V) and Fe(IV) is in the photocatalytic reduction of Fe(VI) by electron (ecb-) on the surface of TiO2. The oxidation efficiency of the photocatalytic oxidation in the pre...

We have developed a relative binding affinity-serum modified access (RBA-SMA) assay to determine the effect of serum on the access of xenoestrogens to estrogen receptors within intact cultured MCF-7 human breast cancer cells. We used this assay to predict low dose activity of two xenoestrogens in mice. In serum-free medium, bisphenol A, a component of polycarbonates and of resins used to line m...

BACKGROUND Although the effect of bisphenol A on various health outcomes has been extensively examined, few studies have investigated its effect on asthma. OBJECTIVE We hypothesized that exposure to bisphenol A in school-age children was associated with wheezing and asthma. METHODS Participants included 127 children aged 7-8 years without a previous asthma diagnosis in an elementary school ...

The widespread human exposure to bisphenol A (BPA), an endocrine disruptor targeting developmental processes, underlines the need to better understand the mechanisms of fetal exposure. Animal studies have shown that at a late stage of pregnancy BPA is efficiently conjugated by the fetoplacental unit, mainly into BPAglucuronide (BPA-G), which remains trapped within the fetoplacental unit. Fetal ...

In order to prepare antibacterial and radio-opaque dental resin, a methacrylate monomer named 2-Dimethyl-2-dodecyl-1-methacryloxyethyl ammonium iodine (DDMAI) with both antibacterial and radio-opaque activities was added into a 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropyl)-phenyl]propane (Bis-GMA)/methyl methacrylate (MMA) dental resin system. Degree of conversion (DC), flexural strength (FS) a...

The effects of four endocrine disruptors: resveratrol, diphenylolpropane (bisphenol-A; BSP), benzophenone-3 (BP3) and silymarin on the secretory and proliferative activity of rat adrenocortical cells were investigated in vitro. Resveratrol and BP3 acutely increased basal corticosterone secretion from freshly dispersed adrenocortical cells, and resveratrol and BSP enhanced ACTH-stimulated cells....

Bis-GMA and epoxy resins are known to cause allergic reactions in some patients. The purpose of this research was to investigate the sensitizing capacity, cross-reactivity and antigenic determinants of bisphenol A (BPA), a major constituent of Bis-GMA and BPA type epoxy resins. Anti-BPA antibodies were prepared from mice injected with BPA-ovalbumin conjugates (BPA-OVA), and the reactions of the...

BACKGROUND Bisphenol-A (BPA) is an industrial chemical, used to manufacture polycarbonate and numerous plastic articles. It has been found to cause biological effects, mimic that of oestrogen. It belongs to a group of chemicals termed "endocrine disruptors" able to disrupt the chemical messenger system in the body. Aim of the study was to demonstrate the biological effects of BPA on the vagina ...
