Preliminary Study on the Removal of Steroidal Estrogens Using TiO2-Doped PVDF Ultrafiltration Membranes

, 2016
Steroidal estrogens are a representative type of endocrine-disrupting chemical contaminant that has been detected in surface water. In this paper, modified polyvinylidene fluoride (PVDF) membranes were prepared by adding different amounts of polyvinyl ...

Sexual dimorphism in hormone–gut microbiome associations across reproductive states in wild giant pandas

iMetaOmics, EarlyView.
Gut microbiota–host endocrine interactions in wild mammals remain poorly understood. Giant pandas experience seasonal dietary shifts and constrained annual reproduction, offering an ideal model to investigate microbiome–endocrine coupling. We integrated fecal hormone profiling, microsatellite‐based individual identification, and gut microbiome ...

Comparison of Short-Term Estrogenicity Tests for Identification of Hormone-Disrupting Chemicals

, 1999
The aim of this study was to compare results obtained by eight different short-term assays of estrogenlike actions of chemicals conducted in 10 different laboratories in five countries. Twenty chemicals were selected to represent direct-acting estrogens,

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Predicting Biological Degradation and Toxicity of Steroidal Estrogens [PDF]

, 2012
This study was to construct a model to predict a variety of biological transformations of Ethinylestradiol (EE2) using electronic theory and to analyze the estrogenic potential of EE2 and its metabolites. As a secondary goal, Frontier Electron Density (

Steroidopathies and hormonal imbalance in children and adolescents with autism spectrum disorder

JCPP Advances, EarlyView.
Abstract Background Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with a multifactorial etiology, many aspects of which remain unclear. Emerging evidence suggests a potential association between ASD and clinical manifestations resulting from hormonal imbalances, henceforth named “steroidopathies.” The present study aims to ...

Assessing the Sensitivity of Different Life Stages for Sexual Disruption in Roach (Rutilus rutilus) Exposed to Effluents from Wastewater Treatment Works

, 2005
Surveys of U.K. rivers have shown a high incidence of sexual disruption in populations of wild roach (Rutilus rutilus) living downstream from wastewater treatment works (WwTW), and the degree of intersex (gonads containing both male and female structural

Immunomodulators, associated or not with systemic antibiotics, to treat periodontitis: A 1‐year multicenter, placebo‐controlled, double‐blind, randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background Immunomodulatory agents such as omega‐3 (ω‐3) and low‐dose aspirin (ASA) have been proposed as effective adjuncts in the treatment of periodontitis. However, they still lack long‐term studies and head‐to‐head evaluation with metronidazole (MTZ) and amoxicillin (AMX), the adjunct protocol with the strongest scientific evidence of ...

Comparison of the toxicokinetics of daidzein and bisphenol A in pregnant and non-pregnant DA/Han rats [PDF]

Potentially adverse human and environmental effects due to hormone mimicry of environmental estrogens are a matter of current concern. Environmental estrogens belong to the socalled endocrine active compounds (EAC) and may alter signalling processes of ...
