Delay in diagnosis of menopause-like condition in young women linked to low bone density

Women and young girls who experience delays in diagnosing a premature, menopause-like condition face increased risk of low bone density, according to new research by scientists at the National Institutes of Health. A delay in diagnosing the condition, called primary ovarian insufficiency, may make women more susceptible to osteoporosis and fractures later in life, the researchers concluded.

“Life force” linked to body’s ability to withstand stress

Our ability to withstand stress-related, inflammatory diseases may be associated, not just with our race and sex, but with our personality as well, according to a study published in the July issue of the journal Brain, Behavior and Immunity. Especially in aging women, low levels of the personality trait extraversion may indicate that blood levels of a key inflammatory molecule have crossed over a threshold linked to a doubling of risk of death within five years.

Could hormones explain gender differences in neurological disease?

Neurological diseases including Parkinson's, Tourette's, attention deficit hyperactivity disorder (ADHD), Alzheimer's, and schizophrenia are all associated with alterations in dopamine-driven function involving the dopamine transporter (DAT).

Nicotine promotes insulin resistance

Researchers have discovered a reason why smoking greatly increases the risk of heart disease and stroke. Nicotine promotes insulin resistance, also called prediabetes, which is a risk factor for cardiovascular disease, according to the new study, which was presented at The Endocrine Society's 91st Annual Meeting in Washington, D.C.

Social moms make better moms, at least in baboons

Female baboons who have strong social relationships with other females give birth to offspring who are much more likely to survive to adulthood than baboons reared by less social mothers, according to a new study by researchers at the University of Pennsylvania, the University of California, Los Angeles, and others.

Hormone therapy may confer more aggressive properties to prostate tumours

Hormone therapy is often given to patients with advanced prostate cancer. While it is true that the treatment prevents growth of the tumour, it also changes its properties. Some of these changes may result in the tumour becoming more aggressive and more liable to form metastases. This is one of the conclusion of a thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden.

A new method for breast cancer biomarker discovery

Three researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed and evaluated a new one-step bioanalytical approach that allows them to profile in detail complex cellular extracts of proteins. The method has allowed the scientists to look at how the levels of proteins change in breast cancer cells when they are treated with hormones or cancer drugs like tamoxifen.
