Specific antagonism lowers blood pressure
High blood pressure (hypertension) is associated with an increased risk of heart attack and stroke, and the frequent use of drugs known as NSAIDs, for example to treat individuals with rheumatoid arthritis, can cause hypertension.   view more (2007-08-17)

HIV accessory protein disables host immunity via receptor-protein intermediary
Researchers at the University of Pennsylvania School of Medicine discovered that an HIV-1 accessory protein called Vpr destroys the host cell's ability to survive by binding to a host receptor.   view more (2006-03-31)

Risk assessment plays key role in long-term treatment of breast cancer
Breast cancer patients and their physicians may make more informed, long-term treatment decisions using risk assessment strategies to help determine probability of recurrence.   view more (2008-08-13)

New path from estrogen to survival in breast cancer cells described
After years of research, scientists at The University of Texas M. D. Anderson Cancer Center are now able to explain, in exquisite molecular detail, how the estrogen hormone can help keep breast cancer cells alive.   view more (2006-09-26)

Researchers discover new way to predict survival in older women with lung cancer
Researchers at UCLA's Jonsson Comprehensive Cancer Center have discovered a novel mechanism to predict survival in older women with early stage lung cancer. The finding may have significant implications for new treatment approaches.   view more (2007-11-02)

Pituitary hormone in menopause under study
Regulating a hormone abundant in women approaching menopause could offer alternatives for hormone replacement therapy, Medical College of Georgia researchers say.   view more (2006-11-03)

Flaxseed shows potential to reduce hot flashes
Data from a new Mayo Clinic (http://mayoclinic.edu) study suggest that dietary therapy using flaxseed can decrease hot flashes in postmenopausal women who do not take estrogen.   view more (2007-08-30)

Odd protein interaction guides development of olfactory system
Scientists have discovered a strange mechanism for the development of the fruit fly antennal lobe, an intricate structure that converts the chaotic stew of odors in the environment into discrete signals in the brain.    view more (2007-10-30)

OHSU researchers discover protein fragment that helps predict breast cancer outcome
Oregon Health & Science University Cancer Institute researchers have identified a protein fragment in some human breast cancers that may help predict a patient's chances of survival.   view more (2006-01-16)

Treatment advances for fibroids, menopause
Women with fibroids and endometriosis facing the possibility of hysterectomy may now choose less invasive treatment options to preserve fertility, according to Yale professor Aydin Arici, M.D., who will direct a scientific session exploring these alternatives at the American College of... view more (2008-05-05)

Chemotherapy and tamoxifen reduce risk of second breast cancer
Among breast cancer patients, both chemotherapy and tamoxifen independently reduced the risk of developing a second cancer in the other breast, according to a study published online December 25 in the Journal of the National Cancer Institute. The risk reduction persisted for at least 10 and 5... view more (2007-12-26)

Studies find no evidence that estrogens in soy increase uterine cancer risk
Studies in monkeys and women suggest that unlike traditional estrogen therapy, a diet high in the natural plant estrogens found in soy does not increase the risk of uterine cancer in postmenopausal women.   view more (2005-11-03)

Soy found protective against localized prostate cancer
The largest study examining the relationship between the traditional soy-rich Japanese diet and development of prostate cancer in Japanese men has come to a seemingly contradictory conclusion: intake of isoflavone chemicals, derived largely from soy foods, decreased the risk of localized prostate... view more (2007-03-16)

Meth Promotes Spread of Virus in HIV-Infected Users
Researchers at the University at Buffalo have presented the first evidence that the addictive drug methamphetamine, or meth, also commonly known as "speed" or "crystal," increases production of a docking protein that promotes the spread of the HIV-1 virus in infected users.   view more (2006-08-07)

Women on hormone therapy regain emotion response
Older women on hormone therapy are more sensitive to negative events, confirming speculation that age-related estrogen loss affects the brain's ability to process emotion, an Oregon Health & Science University study shows.   view more (2006-10-17)

Refuted claims from observational studies often persist despite strong evidence against them
Prominent claims from observational studies of the cardiovascular benefits of vitamin E often continue to be supported in medical literature despite strong contradictory evidence from randomized trials.   view more (2007-12-05)

Hormone use related to lower risk of macular degeneration in postmenopausal women
Women who take postmenopausal hormones appear to have a lower risk of developing advanced stages of the eye disease age-related macular degeneration, especially if they had also taken oral contraceptives in the past, according to a report in the April issue of Archives of Ophthalmology, one of the... view more (2008-04-15)

Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle
Fluctuations in sex hormone levels during women's menstrual cycles affect the responsiveness of their brains' reward circuitry, an imaging study at the National Institute of Mental Health (NIMH), a component of the National Institutes of Health (NIH), has revealed.   view more (2007-02-05)

Biosensor sniffs out explosives
Temple University School of Medicine researchers have developed a new biosensor that sniffs out explosives and could one day be used to detect landmines and deadly agents, such as sarin gas, according to a paper in the June issue of Nature Chemical Biology.   view more (2007-05-09)

Cell-death receptor links cancer susceptibility and inflammation
For over 10 years, Wafik S. El-Deiry, MD, PhD, Professor of Medicine, Genetics, and Pharmacology at the University of Pennsylvania School of Medicine, has been pursuing a cancer-targeting molecule called TRAIL and its molecular partners.   view more (2007-12-28)

Breast cancer and hormone therapy -- A looking-glass mirror?
The medical community has been debating for many years whether, and to what extent, postmenopausal hormone therapy (HT) use is associated with a higher risk of breast cancer, says Professor Amos Pines, President of the International Menopause Society.   view more (2007-07-25)

IL-21 receptor plays an essential role in the Th2 immune response
During the immune response cells known as Th2 cells express a variety of cytokines (e.g. interleukin-4, -5, and -13), many of which stimulate B cells to proliferate and produce antibodies.   view more (2006-06-16)

Study connects obesity with nervous system
