The role of polycarbonate monomer bisphenol-A in insulin resistance
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...
متن کاملMicrobial-mediated release of bisphenol A from polycarbonate vessels.
AIM To identify the source of bisphenol A (BPA) [2,2'-bis(4-hydroxyphenyl) propane] in cultures of an antibiotic-producing Bacillus sp. strain grown in polycarbonate flasks. METHODS AND RESULTS Although a culture of an antibiotic-producing Bacillus sp. strain grown in a new, rinsed polycarbonate flask yielded BPA, duplicate cultures grown in thoroughly washed polycarbonate flasks did not. Cel...
متن کاملPolycarbonate Bottle Use and Urinary Bisphenol A Concentrations
BACKGROUND Bisphenol A (BPA) is a high-production-volume chemical commonly used in the manufacture of polycarbonate plastic. Low-level concentrations of BPA in animals and possibly in humans may cause endocrine disruption. Whether ingestion of food or beverages from polycarbonate containers increases BPA concentrations in humans has not been studied. OBJECTIVES We examined the association bet...
متن کاملFriction Stir Welding of Dissimilar Poly Methyl Methacrylate and Polycarbonate Sheets
The widespread application of thermoplastic polymers in different aspects of industries has motivated researchers and companies to improve and upgrade their forming, joining and assembling processes to overcome their limitations. One of the newest joining methods of thermoplastics is friction stir welding which is based on frictional heat generated through contact between a rotating tool and th...
متن کاملThe Role of Transesterification on the Miscibility in Blends of Polycarbonate and Liquid Crystalline Copolyester
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...
