Prostate cancer drug, Omnitarg by Genentech falls short

Research into an experimental prostate cancer drug being developed by Genentech Inc. will probably be abandoned after scientists found that the drug failed to prove effective in a mid-stage trial.

Swedish study suggests gay men's brains differ from heterosexual men's

Researchers in Sweden have found that a compound taken from male sweat stimulates the brains of gay men and straight women but not heterosexual men, which raises the possibility that homosexual brains are different.

Simple and efficient method for creation of novel protein functions in an existing protein scaffold

By designing a molecular bridge, scientists at the University of Illinois at Urbana-Champaign have forged a successful pathway through a complex ocean of barriers: They've changed the function of a protein using a co-evolution approach.

New study confirms 'wait and see' approach best for some prostate cancers

Men diagnosed with low-grade localized prostate cancer who opt not to undergo aggressive treatment for the disease are unlikely to die of the disease, even after 20 years, according to researchers in Connecticut.

Statins help cut risk for advanced prostate cancer

In a 10-year study of more than 30,000 health professionals, researchers at Johns Hopkins and Harvard found that the longer men take cholesterol-lowering drugs such as statins, the far less likely they are to develop advanced prostate cancer.

Men have a four times greater risk than women of developing abdominal aortic aneurysms

Men have a four times greater risk than women of developing abdominal aortic aneurysms, estimated to be the cause of death in 4 percent of people over the age of 65, but the mechanism for this higher incidence has remained unknown.

New color-coded test for protein folding

Every protein--from albumin to testosterone--is folded into a unique, three-dimensional shape that allows it to function properly. Now Stanford University scientists have developed a simple test that instantly changes color when a protein molecule attached to a gold nanoparticle folds or unfolds.

Timing is everything when it comes to killing prostate cancer cells

"The window of opportunity is narrow for vaccination, designed to reinvigorate the immune system's attack on cancer cells, and it occurs right after hormonal therapy begins to wipe out the tumor and immune cells outnumber cancerous ones," according to Charles Drake, M.D., Ph.D.

Women prefer men with deep voices

Sarah Evans, a part-time psychology lecturer and PhD student, found that women consider deep voices more attractive, dominant, masculine, sexy, assertive, confident and friendly.

A man's index finger length relative to ring finger length can predict how physically aggressive that man might be

Dr. Peter Hurd a psychologist at the University of Alberta, and his graduate student Allison Bailey, have found that a man's index finger length relative to ring finger length can predict how physically aggressive that man might be.

Hormone therapy for prostate cancer can affect men's thinking

Androgen-deprivation therapy (AD), an effective therapy in the treatment of prostate cancer reduces levels of testosterone (a tumor stimulant), and estradiol, a form of estrogen, in men. These are known to be important in neurological development and play a particularly important role in the cognitive areas of learning and memory.

Testosterone spray improves younger women's sexual enjoyment and satisfaction

Improved sexual satisfaction for women could be just a spray on the skin away, according to the results of clinical trials led by a Monash University research team.

What causes puberty to begin?

Puberty, that awkward phase when boys and girls are primed for their sexual reproductive years as men and women, appears to be triggered by the brain's own version of "It takes two to tango," whereby a signal literally gets turned on by a molecule that is produced by a gene aptly named KiSS-1.

Why some men develop aggressive prostate cancer that becomes resistant to hormone-withdrawal therapy

Researchers found that certain mutations in a protein called the androgen receptor cause advanced and invasive prostate cancer when put into otherwise healthy mice. The androgen receptor's normal function is to control growth of the prostate gland in response to cues from male hormones called androgens, which have long been thought to stimulate prostate tumors.

Sex hormones modulate brain damage in multiple sclerosis

Abnormalities in sex hormone levels may contribute to the damage to brain tissue typical of multiple sclerosis, indicates research in the Journal of Neurology Neurosurgery and Psychiatry.

Pancreatic beta-cells play an important role in the existence of polycystic ovary syndrome (PCOS)

Researchers have discovered that pancreatic beta-cells, which are responsible for insulin secretion, play an important role in the existence of polycystic ovary syndrome (PCOS), a hormonal disorder that affects up to 10 percent of reproductive aged women.

Exposure to the chemical BPA (Bisphenol A) stimulates prostate cancer cell growth

An estrogen-like chemical commonly used to synthesize plastic food containers has been shown to encourage the growth of a specific category of prostate cancer cell, potentially affecting the treatment efficacy for a subset of prostate cancers.
