Breast cancer prognosis predicted by protein

Researchers have identified a protein that they believe may help predict breast cancer prognosis, potentially relieving thousands of women at low risk from having to undergo painful, oft-debilitating therapies, while insuring the most successful treatments for those at high risk. The research was published ahead of print in the journal Molecular and Cellular Biology. Using bioinformatics techniques, the authors showed that the levels of expression of some 1,200 genes that are directly controlled by the enzyme, EZH2, correlates with the aggressiveness of breast cancer cases...

In 1st human brain-to-brain interface, researcher controls colleague's motions

University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher. Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of the UW campus, causing Stocco's finger to move on a keyboard...

The absence or presence of a single protein can make cancer cells more or less susceptible to drugs

A new weakness has been discovered in cancer cells that may make them more susceptible to chemotherapy and other treatments. In a research report appearing in the September 2013 issue of The FASEB Journal, scientists identify the HDAC5 protein as being essential for the maintenance of structures, called telomeres, within cancer cells that promote cancer cells longevity. Cancer cells with longer telomeres tend to be more resistant to therapies, while cancer cells with shorter telomeres tend to be more susceptible...

Standard antibiotics plus blood pressure drug speeds up TB treatment

Infectious disease experts at Johns Hopkins have found, in studies in mice, that a drug better known as a treatment for high blood pressure and headaches effectively speeds up treatment of TB when added to the standard, daily antibiotic regimen. Test animals were cured in four months instead of the usual six...

Unintentional opioid exposure in young children can be lethal

Medication poisonings among children are an important public health problem. During 2010-2011, an average of 1500 children under 6 years of age was evaluated in emergency departments each year due to unintentional exposure to buprenorphine. Ingestion of strong opioids, such as buprenorphine, can cause central nervous system depression, respiratory depression, and death in young children...

New guidance on vulvovaginal atrophy issued by NAMS

Symptoms of vulvovaginal atrophy (VVA), such as lack of lubrication, irritated tissues, painful urination, and pain with intercourse, affect as many as 45% of women after menopause. That's according to The North American Menopause Society (NAMS), which has published new guidance for diagnosing and treating VVA. The Society's Position Statement "Management of Vulvovaginal Atrophy" appears in the September issue of Menopause. "The symptoms of VVA can significantly impair women's quality of life and relationships, yet few women whose lives are affected get help...

Men's subconscious self-esteem related to female partner's successes and failures

Deep down, men may not bask in the glory of their successful wives or girlfriends. While this is not true of women, men's subconscious self-esteem may be bruised when their spouse or girlfriend excels, says a study published by the American Psychological Association. It didn't matter if their significant other was an excellent hostess or intelligent, men were more likely to feel subconsciously worse about themselves when their female partner succeeded than when she failed, according to the study published online in the APA Journal of Personality and Social Psychology...
