A review published online June 22 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP) reports the conclusions of an international workshop on ways to improve chemicals safety testing for effects on the breast. The studies reviewed by workshop scientists indicate that chemical exposures during critical periods of development may influence breast growth, ability to breastfeed, and cancer risk. The scientists recommend that future chemical testing evaluate effects on the breast after prenatal and early-life exposure.

Coming out as lesbian, gay, or bisexual increases emotional well-being even more than earlier research has indicated. But the psychological benefits of revealing one’s sexual identity -- less anger, less depression, and higher self-esteem – are limited to supportive settings, shows a study published June 20 in Social Psychology and Personality Science. The findings underscore the importance of creating workplaces and other social settings that are accepting of all people, but especially gay, lesbian or bisexual individuals.

Mayo Clinic investigators and collaborators from the United Kingdom cured well-established prostate tumors in mice using a human vaccine with no apparent side effects. This novel cancer treatment approach encourages the immune system to rid itself of prostate tumors without assistance from toxic chemotherapies and radiation treatments. Such a treatment model could some day help people to live tumor free with fewer side effects than those experienced from current therapies.
Researchers at Fred Hutchinson Cancer Research Center have demonstrated in mice that the performance of a novel biomarker-development pipeline using targeted mass spectrometry is robust enough to support the use of an analogous approach in humans.

The findings are published in the June 16 issue of the New England Journal of Medicine.

Bariatric surgery can cut the incidence of heart attack, stroke or death by as much as 50 percent, according to a new study* presented here at the 28th Annual Meeting of the American Society for Metabolic & Bariatric Surgery (ASMBS).
Obesity has been linked to infertility and now a new study shows bariatric surgery may treat its most common cause, polycystic ovarian syndrome (PCOS), a hormonal imbalance that affects up to 10 percent of women of child-bearing age -- 33 to 50 percent of whom are overweight or obese.

Engaging this signaling pathway and its capacity to govern cell differentiation has important implications in preventing obesity and cardiovascular disease. The study is published in the June issue of Developmental Cell.

A new study provides support for Darwin’s hypothesis that the struggle for existence is stronger between more closely related species. While ecologists generally accept the premise, this new study contains the strongest direct experimental evidence yet to support its validity.
In one of the first studies of its kind, UCLA researchers used a unique brain scan to assess the levels of plaques and tangles — the hallmarks of Alzheimer's disease — in adults with Down syndrome. The finding may offer an additional clinical tool to help diagnose dementia in adults with Down syndrome. Adults with this disorder develop Alzheimer's-like plaque and tangle deposits early, often before the age of 40.
