Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy.

Modern-day Chinese pigs are directly descended from ancient pigs which were the first to be domesticated in the region 10,000 years ago, a new archaeological and genetic study has revealed.
An international team of researchers, led by Durham University (UK) and the China Agricultural University, in Beijing, say their findings suggest a difference between patterns of early domestication and movement of pigs in Europe and parts of East Asia.
BINGHAMTON, NY – In each of two cities, a team of local agencies launches a campaign to keep children from joining gangs. The two use similar tactics, combining counseling, tutoring and recreation. One initiative shows great results; the other makes barely a dent. Why the difference?
The research of Pamela Mischen, associate professor of public administration at Binghamton University, demonstrates that one program may have failed because the right people weren't talking.
Washington, DC – A high level of one type of estrogen in a man's body might increase his risk of developing prostate cancer. That is one surprising conclusion from a new study which also offers another novel finding – that high levels of the estrogen considered fuel for breast cancer might offer a protective benefit against prostate cancer. Details of the research will be presented at the AACR 101st Annual Meeting 2010.
WASHINGTON, D.C. — Researchers at Johns Hopkins have evaluated a simple, more specific blood test that identifies patients undergoing proactive surveillance for low-grade, low-stage, non-palpable prostate cancer who would eventually require treatment.
These results, presented at the American Association for Cancer Research 101st Annual Meeting 2010, may be a major advance in prostate cancer risk assessment.
PHILADELPHIA (April 19, 2010)—Lung cancer rates are increasing substantially in women, particularly in non-smoking women, with no known reason for the increase. Now researchers at Fox Chase Cancer Center may have uncovered a critical piece in the puzzle.
WASHINGTON, D.C. (April 19, 2010)––Most treatment for advanced head and neck cancer requires chemotherapy with a drug called cisplatin, an inorganic platinum agent that inhibits cell growth. A substantial number of patients do not respond well to this therapy, but oncologists are unable to prescribe alternative agents because they don't know which patients will respond to platinum therapy and which won't.
WASHINGTON, D.C. - People who eat meat frequently, especially meat that is well done or cooked at high temperatures, may have a higher chance of developing bladder cancer, according to a large study at The University of Texas M. D. Anderson Cancer Center presented at the American Association for Cancer Research 101st Annual Meeting 2010. This risk appears to increase in people with certain genetic variants.
A blood test for certain forms of prostate specific antigen (PSA) and measurement of DNA content in biopsy tissue accurately predict which men with potentially non-lethal prostate cancers may eventually need treatment, say Johns Hopkins scientists.
Many companies grow by extending their brands into new types of products. A new study in the Journal of Consumer Research examines why some of those new products succeed and others fail.
When products don't easily fit into our goals, we experience conflict. According to a new study in the Journal of Consumer Research, conflicted consumers are easily swayed by unwanted influences.
Consumers who choose between two good product options build a "positivity bubble" to justify their choices. But according to a new study in the Journal of Consumer Research, that bubble is easy to burst.
"From routine cereal-aisle shopping to expensive big-ticket purchases, consumers are often free to choose among many similarly attractive options," write authors Ab Litt and Zakary L. Tormala (Stanford University). "In these contexts, it can be difficult to resolve one's preferences to arrive at a purchasing decision."
Chapel Hill, NC – Rho proteins have been described as "molecular switches" and play a role in cell migration, cell proliferation, cell death, gene expression, and multiple other common cellular functions.
Understanding the actions of Rho proteins is important to illuminating cellular mechanisms related to cancer, which is fundamentally a disease of cell misbehavior. When cells multiply too rapidly, multiply and migrate into inappropriate places in the body, do not die after their natural lifespan or create networks of blood vessels where they should not, cancer results.
Scientists investigating ovale malaria, a form of the disease thought to be caused by a single species of parasite, have confirmed that the parasite is actually two similar but distinct species which do not reproduce with each other, according to research published in The Journal of Infectious Diseases.
WASHINGTON, D.C. -- A blood test used to determine the level of inflammation in the body may offer some help in assessing colon cancer risk, according to results of a study to be presented by Vanderbilt-Ingram Cancer Center's Gong Yang, M.D., MPH, at the 101st Annual Meeting of the American Association for Cancer Research (AACR).
Yang and colleagues show that levels of C-reactive protein (CRP), a protein produced by the liver in response to inflammation, are increased in women with colon cancer.
