Gender-based violence associated with lifetime risk of mental illness and disability, research shows

Women who experience gender-based violence such as rape, sexual assault, intimate partner violence and stalking have a higher lifetime prevalence of mental health disorders, dysfunction and disability, new Australian research shows.

The survey of 4,451 women aged 16 to 85 used international instruments developed by the World Health Organisation. Around 15 percent of Australian women report sexual assault, while eight percent report being raped. About eight percent report physical intimate partner violence and 10 percent stalking.

Scientists probe the energy transfer process in photosynthetic proteins

College Park, Md. (August 2, 2011) -- Researchers have developed a new method to probe the fundamental workings of photosynthesis. The new experimental technique could help scientists better understand the nitty-gritty details of nature's amazingly efficient sunlight-to-fuel conversion system.

Study: Inexpensive method detects ALK rearrangement in lung cancer patients

A relatively simple and inexpensive method may be used to determine whether a lung cancer patient is a candidate for crizotinib therapy, according to research published in the August issue of the Journal of Thoracic Oncology, the official monthly journal of the International Association for the Study of Lung Cancer (IASLC).

UNH researchers help find natural products potential of frankia

DURHAM, N.H. – Soil-dwelling bacteria of the genus Frankia have the potential to produce a multitude of natural products, including antibiotics, herbicides, pigments, anticancer agents, and other useful products, according to an article in the June 2011 issue of the journal "Applied and Environmental Microbiology." University of New Hampshire professor of microbiology and genetics Louis Tisa, a Frankia expert, contributed the genomic analysis to this study.

African rodent uses 'poison arrow' toxin to deter predators

Woe to the clueless predator trying to make a meal of the African crested rat, a rodent that applies poisonous plant toxin to sponge-like hairs on its flanks, a discovery recently made by Jonathan Kingdon and colleagues from the National Museums of Kenya, the Wildlife Conservation Society, and University of Oxford.

Plant biologists dissect genetic mechanism enabling plants to overcome environmental challenge

Cold Spring Harbor, NY -- When an animal gets too hot or too cold, or feels pangs of hunger or thirst, it tends to relocate – to where it's cooler or hotter, or to the nearest place where food or water can be found. But what about vegetative life? What can a plant do under similar circumstances?

Plants can't change the climate and they can't uproot themselves to move to a more favorable spot. Yet they do respond successfully to changes in environmental conditions in diverse ways, many of which involve modifications of the way they grow and develop.

Lifestyles of the old and healthy defy expectations

August 3, 2011 — (Bronx, NY) — People who live to 95 or older are no more virtuous than the rest of us in terms of their diet, exercise routine or smoking and drinking habits, according to researchers at Albert Einstein College of Medicine of Yeshiva University.

Urine test shows prostate cancer risk, U-M study finds

ANN ARBOR, Mich. — A new urine test can help aid early detection of and treatment decisions about prostate cancer, a study from the University of Michigan Comprehensive Cancer Center and the Michigan Center for Translational Pathology finds.

The test supplements an elevated prostate specific antigen, or PSA, screening result, and could help some men delay or avoid a needle biopsy while pointing out men at highest risk for clinically significant prostate cancer.

Unconventional hunt for new cancer targets leads to a powerful drug candidate for leukemia

Cold Spring Harbor, N.Y. – Scientists at Cold Spring Harbor Laboratory (CSHL) and five other institutions have used an unconventional approach to cancer drug discovery to identify a new potential treatment for acute myeloid leukemia (AML). As reported in Nature online on August 3, the scientists have pinpointed a protein called Brd4 as a novel drug target for AML, an aggressive blood cancer that is currently incurable in 70% of patients. Using a drug compound that inhibits the activity of Brd4, the scientists were able to suppress the disease in experimental models.

Natural killer cells participate in immune response against HIV

A new study shows for the first time that natural killer (NK) cells, which are part of the body's first-line defence against infection, can contribute to the immune response against HIV. In an article in the August 4 issue of Nature, a research team based at the Ragon Institute of MGH, MIT and Harvard reports that the HIV strains infecting individuals with particular receptor molecules on their NK cells had variant forms of key viral proteins, implying that the virus had mutated to avoid NK cell activity.

Anti-cancer therapy: Starving cancer cells of glucose

STANFORD, Calif. — Stanford University School of Medicine researchers have identified a compound that attacks the Achilles' heel of certain cancer cells by depriving them of their energy source, the sugar glucose.

Combination of existing safety checks could greatly reduce radiotherapy errors

A combination of several well-known safety procedures could greatly reduce patient-harming errors in the use of radiation to treat cancer, according to a new study led by Johns Hopkins researchers.

Research links diet during pregnancy to breast cancer risk reduction in female offspring

ORLANDO, Fla. — August 3, 2011 — During pregnancy, women are counseled to refrain from consuming certain types of foods, beverages and medications in order to avoid jeopardizing the health and development of the fetus. In fact, the American Pregnancy Association has a list of a dozen items they recommend expectant mothers omit from their diets.

Fighting breast cancer from new angles

ORLANDO, Fla. — August 3, 2011 — In their lifetime, women have more than a 12 percent risk of being diagnosed with breast cancer. 1 This week, research on novel approaches to breast cancer treatment is being presented at the Era of Hope (EOH) conference, a scientific meeting hosted by the Department of Defense Breast Cancer Research Program (BCRP).

Research explores how breast cancer spreads and new ways to treat it

ORLANDO, Fla. — August 3, 2011 — Research into new methods to prevent and slow metastatic breast cancer will be presented this week at the Era of Hope conference, a scientific meeting hosted by the Department of Defense Breast Cancer Research Program (BCRP). Approximately 6 percent of women with breast cancer will have metastatic disease upon diagnosis, and up to 30 percent of node-negative and 70 percent of node-positive breast cancers will relapse. 1 Common sites for breast cancer to spread are to the lungs, liver, brain and bones.
