Cognitive Effects of Estrogens During Aging
… an important role in mediating the effects of estrogens on executive function.

Nongenomic Effects of Estrogens on Epithelial Chloride Secretion.
… was used to investigate the regulatory role of estrogens in transepithelial ion transport. Estrogens and other steroid hormones do not stimulate chloride secretion by themselves. However, 17 β-estradiol (17β-E2) rapidly (within seconds to minutes) potentiates carbachol- and …

Effects of Estrogens on Astrocytes Exposed to Stressors
… is often a combination of horomones such as estrogens, progesterone, and conjugated equine estrogens (CEE), extracted from the urine of pregnant mares. Previous studies have found positive correlations between estradiol and cellular protection, but recent research has concluded CEE provide …

Synthesis of Functional Analogs of Non-Steroidal Estrogens
… of several new, functionalized non-steroidal estrogens is reported. With the aim of developing an estrogen receptor-based radiopharmaceutical, two new iodinated estrogens, 1-(2'-iodo-4'-hydroxyphenyl)-2-(4'-hydroxyphenyl)butane and …

The Development of 2,3-Diarylindenes as Integrated Fluorescent Estrogens
… -indenones were inefficient as photofluorogenic estrogens due to geometric considerations and competition from fluorescence and intersystem crossing. Crystallography indicated more planar topography for the indenes and indenones as compared to other triarylethylenes. The estrogen receptor binding …

Labeling of Proteins, Peptides, and Estrogens With Cyclopentadienyltricarbonylrhenium and Technetium
The conjugation of cyclopentadienyltricarbonylrhenium to molecules having an affinity for the estrogen receptor is described. A variety of derivatives were prepared using either an indirect labeling or a preformed chelate approach, and of the compounds synthesized, …

Enterohepatic Circulation of Estrogens in the Domestic Pig, Sus Scrofa
Enterohepatic circulation (EHC) of estrogen involves secretion of estrogen in bile by the liver, release of bile from the gallbladder into the gastrointestinal tract, absorption of estrogen in bile from the gastrointestinal tract into venous blood going to the liver, and secretion of estrogen by …

Development of Novel anti-estrogens for endocrine resistant Breast Cancer
ER+ breast cancer raises a significant diagnostic challenge since resistance invariably develops to the current endocrine therapies. 70% of breast cancers are ER+, which results from the overexpression of estrogen receptor. ER mediates strong anti-inflammatory signaling in ER+ tissues. Once …

INVOLVEMENT OF LYSOSOMES IN SPONTANEOUS ATHEROGENESIS AND THE EFFECTS OF ESTROGENS
… atherogenesis or lesion progression is unclear. Estrogens have been reported to interact with lysosomes and are thought to provide a "protective" effect against development of atherosclerotic lesions. Analysis of lysosomes from sites predisposed to lesions, as well as consideration of the effects …

The nongenomic effects of physiological and environmental estrogens on dopamine transporter function
… nongenomic effects of several physiological estrogens [estradiol (E2) estrone (E1), and estriol (E3)] and xenoestrogens (XEs), such as organochlorine pesticides [dieldrin, endosulfan, and o¡¯,p¡¯-dichlorodiphenylethylene (DDE)], plastics manufacturing by-products/detergents (nonylphenol, …

Sorption, degradation and transport of estrogens and estrogen sulphates in agricultural soils
The fate and behaviour of estrogens in the environment are of concern due to the compounds’ endocrine disruption potential. Estrogens, namely 17β-estradiol (E2), estrone (E1), and estrogen sulphates, i.e. 17β-estradiol-3-sulphate (E2-3S) and estrone-3-sulphate (E1-3S) excreted by livestock …

Removal of Estrogens at Full and Pilot Scale Livestock Manure Treatment Systems
… manure after a base extraction and analysis of estrogens by enzyme-linked immunoassay (ELISA) and yeast estrogen screen (YES) assay. The recoveries of E2 were 104% (ELISA) and 97% (YES) in double distilled water. 112% of E2 and 79% of E3 in flushed dairy manure and 118% of E2 in anaerobic …

Natural and synthetic estrogens in wastewater treatment plant effluent and the coastal ocean
Steroidal estrogens are potent endocrine disrupting chemicals that are naturally excreted by vertebrates (e.g., humans and fish) and can enter natural waters through the discharge of treated and raw sewage. Because estrogens are detrimental to aquatic organisms at picomolar concentrations, many …
