Abstract Background and objectives The presence of endocrine disruptors in food is creating concern, consequently, efficient methods for their identification are needed. In vitro bioassays have been developed to study properties pure chemicals as well mixtures. Because relative ease execution low cost, application such techniques whole foods tempting. This raises a number technical challenges. ...

This study was conducted to reveal the estrogenic effects of bisphenol A and o, p’-DDT on quailembryos. Thirteen fertilized eggs were used as control (injected with 20 μl corn oil), 15 eggs were injectedwith estradiol 17β (0.04 mg dissolved in 20 μl corn oil), 20 eggs were injected with BPA (2 mg dissolved in20 μl corn oil) and 20 eggs were injected with o, p’-DDT (2 mg dissolved in 20 μl corn ...

Abstract Effluents from municipal wastewater treatment plants (MWTPs) are complex mixtures of chemicals including endocrine-disrupting compounds (EDCs) and 17?-ethynylestradiol (EE2). The objective this study was to evaluate selected responses two fish species, in different years, exposed situ MWTP effluent. Biological markers exposure (plasma vitellogenin (VTG) antioxidant enzymes) were measur...

The estrogenic activity of the chemical UV-filters, 4-methylbenzylidene camphor (4-MBC) and octyl methoxy cinnamate (OMC) was investigated in an vivo rainbow trout ( Oncorhynchus mykiss ) assay. Plasma vitellogenin concentrations were quantified by means Enzyme Linked Immuno Sorbent Assay (ELISA) juvenile before after intraperitoneal injection test compounds. Injection 4-MBC on day 0, 3, 6 10 e...

The rapid evolution of antibiotic resistance in bacteria is one of the most pressing public health problems in the nation. According to the Center for Disease Control, over 70% of the bacteria that cause hospital-acquired infections are resistant to at least one commonly prescribed drug. The fight against antibiotic resistance is primarily focused on clinical settings. Antibiotic resistant bact...
