International journal of andrology, 35(3), 397-406 (2012-05-23)
There is growing concern of exposure of fish, wildlife and humans to water sources contaminated with oestrogens and the potential impact on reproductive health. Environmental oestrogens can come from various sources including concentrated animal feedlot operations (CAFO), municipal waste, agricultural

Molecular and cellular endocrinology, 339(1-2), 136-143 (2011-05-04)
In this work we provide evidence that estrone "per se" modulates cellular endothelial growth and survival, events that play key roles in the development of vascular disease. Moreover, under oxidative stress conditions the hormone prevented apoptosis triggered by hydrogen peroxide.

Journal of chromatography. A, 1083(1-2), 42-51 (2005-08-05)
Equilin-3-sulfate and delta8,9-dehydroestrone-3-sulfate are two isomers found in equine conjugated estrogens that differ in structure only by the position of a double bond in the steroid B-ring. These geometric isomers were not resolved on a C18 column during the analysis

Estrone (E1), 17β-estradiol (E2), estriol (E3), equilin (EQ) and 17α-estradiol (17α) estrogen hormones are released by humans and animals and have been detected in the environment and municipal wastewater treatment plants. The structural and electronic properties of natural hormone molecules
