BPA exposure reduces quality of womens' eggs retrieved for IVF

A small-scale University of California, San Francisco-led study has identified the first evidence in humans that exposure to bisphenol A (BPA) may compromise the quality of a woman's eggs retrieved for in vitro fertilization (IVF). As blood levels of BPA in the women studied doubled, the percentage of eggs that fertilized normally declined by 50 percent, according to the research team.

Protein p53 plays crucial role in coordinated growth of organ parts

In studies conducted on the fruit fly, researchers at IRB Barcelona headed by ICREA Professor Marco Milán have revealed that organs have the molecular mechanisms to control their proportions. In this process the protein p53 plays a crucial role. The study is published today in the prestigious journal PLoS Biology.

UCLA findings could lead to enhanced health supplements, progress on Parkinson's

The discovery by UCLA biochemists of a new method for preventing oxidation in the essential fatty acids of cell membranes could lead to a new class of more effective nutritional supplements and potentially help combat neurodegenerative disorders such as Parkinson's disease and perhaps Alzheimer's.

Doctors still prescribe higher-dose menopausal hormone therapy pills

Doctors across the country are still prescribing higher-dose menopausal hormone therapy pills, despite clinical evidence that low doses and skin patches work just as well and carry fewer health risks. That's what researchers at the Stanford University School of Medicine found in a study that will be published online Dec. 2 in Menopause: The Journal of the North American Menopause Society.

Diabetes plays a vital role in regulating brain cholesterol: Research

The brain contains more cholesterol than any other organ in the body, has to produce its own cholesterol and won't function normally if it doesn't churn out enough. Defects in cholesterol metabolism have been linked with Alzheimer's disease and other neurodegenerative conditions. Now researchers at Joslin Diabetes Center have discovered that diabetes can affect how much cholesterol the brain can make.

Study shows link between reduced hormone therapy and decline in breast cancer

In a new UCSF study of more than 2 million mammogram screenings performed on nearly 700,000 women in the United States, scientists for the first time show a direct link between reduced hormone therapy and declines in ductal carcinoma in situ (DCIS) as well as invasive breast cancer. The researchers saw such a striking decrease, they believe they also have uncovered indirect evidence that hormones promote breast tumor growth.

Depressed and suicidal individuals linked to low levels of stress hormone cortisol

Depressed and suicidal individuals have low levels of the stress hormone cortisol in their blood and saliva. They also have substances in their spinal fluid that suggest there is increased inflammation in the brain.
