Endocrine-disrupting chemicals are exogenous substances that alter the function of endocrine system, with adverse health effects on organisms or their progeny. In vitro estrogen receptor (ER) reporter gene assays have long been used to measure estrogenic activity in wastewater. Nevertheless, there is still uncertainty about usefulness environmental monitoring account a discrepancy between response assay and concentrations compounds determined by chemical analysis. Here, we measured...

The in vitro estrogen receptor (ER) reporter gene assay has long been used to measure estrogenic activity wastewater. In a previous study, we demonstrated that the represents net balance between and antiestrogenic activities However, it remained unclear whether measured by ERα can predict vivo effect of To determine this, following: wastewater reclaimed water assay, expression vitellogenin-1 (vtg1) choriogenin-H (chgH) male medaka (Oryzias latipes) quantitative real-time PCR, estrone,...

The synthesis of high-molecular-weight lactic-acid-based polymers by chain-linked polymerization was investigated. A hydroxyl-terminated telechelic pre-polymer synthesized and then it with methylene diphenyldiisocyanate (MDI). All polymerizations were carried out in the melt, using tin octoate as catalyst. products characterized dynamic mechanical analyzer, Fourier transform infrared spectroscopy, thermogravimetric analysis viscometry. With increase diisocyanate concentration, increases...

A simple model was set up to predict estrogen concentrations and endocrine disruption risk in the Yodo River, Japan. This catchment spans conurbations of Kyoto Osaka is main source drinking water for City, From river survey data (5 separate occasions between 2005 2008), a maximum 32 g per day estrone (E1) load observed most downstream site river. Predicted E1 were reasonable agreement with measurements taken at several points within basin from series sampling campaigns. The predicted...

This study describes the occurrence, fate,and removal of free estrogens (estrone (E1), 17β‐estradiol (E2), estriol (E3), 17α‐ethynylestradiol (EE2)) and their glucuronide sulfate conjugates (estrone‐3‐sulphate (E1‐3S), 17β‐estradiol‐3‐sulfate (E2‐3S), estriol‐3‐sulfate (E3‐3S), estrone‐3‐glucuronide (E1‐3G), 17β‐estradiol‐3‐glucuronide (E2‐3G), estriol‐3‐glucuronide (E3‐3G)) in 12 sewage treatment plants Japan. Glucuronide were only rarely detected influents entirely eliminated within...

The drumstick tree, Moringa oleifera, is a multi-purpose plant showing several beneficial effects, depending on part origin. seeds for example show potential anti-biotic activity against certain pathogenic bacteria species. Furthermore they can be used water purification since contain specific proteins with coagulation properties. In these experiments we tested the effects of dietary M. oleifera seed protein extracts (MPE) growth performance, nutrient utilization and blood parameters common...
