When combined with antipsychotic medications, the estrogen estradiol appears to be a useful treatment in women with schizophrenia, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Chronic exposure to estrogen impairs some cognitive functions

University of Illinois researchers report this week that chronic exposure to estradiol, the main estrogen in the body, diminishes some cognitive functions. Rats exposed to a steady dose of estradiol were impaired on tasks involving working memory and response inhibition, the researchers found.

Cholesterol byproduct blocks heart health benefits of estrogen

New findings by UT Southwestern Medical Center researchers show that a byproduct of cholesterol metabolism interferes with the beneficial effects estrogen has on the cardiovascular system, providing a better understanding of the interplay between cholesterol and estrogen in heart disease.

Role of oxidative stress in estrogen-related bone loss

Scientists have discovered new information about an immune pathway in mice that explains how oxidative stress that results from acute estrogen deficiency leads to the loss of bone. The finding, published in the Proceedings of the National Academy of Sciences, could help in identifying a new drug target for preventing postmenopausal bone loss.

In the largest study of its kind, Mayo Clinic researchers have shown that women who had one or both ovaries removed before menopause faced an increased long-term risk of cognitive impairment or dementia, compared to women who retained their ovaries.

Positive clinical trial results with combination contraceptive sprays

The Australian drug delivery company, today announced positive results from its Phase 1 clinical studies using two unique contraceptive skin sprays, each containing a progestin and an estrogen.

Estrogen fluctuation affects epileptic seizures

In more than a third of women with epilepsy, seizures fluctuate across the menstrual cycle, due in part to continually fluctuating effects of estrogen on the neural circuitry in the hippocampus, a region of the brain involved in learning and memory - and in epileptic seizures.

Estrogenic activity documented in fish caught in Pittsburgh's rivers

harminka — Tue, 17 Apr 2007 12:31:51 -0500

A new study from the University of Pittsburgh Cancer Institute's Center for Environmental Oncology suggests that fish caught in Pittsburgh rivers contain substances that mimic the actions of estrogen, the female hormone. Since fish are sentinels of the environment, and can concentrate chemicals from their habitat within their bodies, these results suggest that feminizing chemicals may be making their way into the region's waterways.

Estrogen protects liver after traumatic injury

Researchers have identified the receptor pathway used by estrogen to decrease liver injury after trauma and hemorrhage. The related report by Hsieh et al, "G protein-coupled receptor 30-dependent protein kinase A pathway is critical in nongenomic effects of estrogen in attenuating liver injury after trauma-hemorrhage,"Â appears in the April issue of The American Journal of Pathology and is accompanied by a commentary.

Describing Action of Estrogen in Protecting Bone

Researchers at the University at Buffalo have described a novel pathway by which estradiol, the primary estrogen in humans, aids in maintaining bone density, a function critical to avoiding osteoporosis.
