UCLA team develops highly efficient method for creating flexible, transparent electrodes

As the market for liquid crystal displays and other electronics continues to drive up the price of indium -- the material used to make the indium tin oxide (ITO) transparent electrodes in these devices -- scientists have been searching for a less costly and more dynamic alternative, particularly for use in future flexible electronics.

UT Southwestern team identifies tumor-specific pathway

DALLAS -- A research team led by UT Southwestern Medical Center scientists has identified an atypical metabolic pathway unique to some tumors, possibly providing a future target for drugs that could reduce or halt the spread of cancer.

Dr. Ralph DeBerardinis, senior author of the study published Nov. 20 in Nature, likened the newly discovered pathway to traffic that is rerouted during a highway construction project.

Wildlife access critical to children's health

For the first time, researchers have uncovered a powerful connection between loss of access to wildlife and micronutrient deficiencies in children, according to a recently published study by the University of California-Berkeley, Harvard Center for the Environment and Harvard School of Public Health, the Wildlife Conservation Society, and others.

Cancer screening reform needed

Since the National Cancer Institute developed the first guidelines on mammography screening over thirty years ago, advocacy and professional groups have developed guidelines focused on who should be screened, instead of communicating clearly the risks and benefits of screening, according to a commentary by Michael Edward Stefanek, Ph.D., the associate vice president of collaborative research in the office of the vice president at Indiana University, published online Nov.

Treatment of acne using oral antibiotics associated with reporting symptoms of sore throat

CHICAGO – Taking oral antibiotics for treatment of acne appears to be associated with reporting symptoms of pharyngitis (sore throat), according to a report published Online First by Archives of Dermatology, one of the JAMA/Archives journals.

Mortality rates for pharynx and mouth cancers have decreased

CHICAGO – Death rates have declined among U.S. patients with cancer of the mouth and pharynx from 1993 to 2007, with the greatest decreases seen among men and women with at least 12 years of education, according to a report in the November issue of the Archives of Otolaryngology – Head & Neck Surgery, one of the JAMA/Archives journals.

Life-threatening condition in preemies linked to blood type

MAYWOOD, Ill. -- Many premature infants suffer a life-threatening destruction of intestinal tissue called necrotizing enterocolitis (NEC).

Now a Loyola University Medical Center study has identified a major risk factor for NEC: Preemies with the AB blood type who develop NEC are nearly three times as likely to die from it as preemies with other blood types.

The finding suggests that a simple change in blood transfusion practices in neonatal ICUs could significantly reduce the incidence of NEC.

Canadian breast cancer screening guidelines would cost thousands of lives

The American College of Radiology today denounced new breast cancer screening guidelines by the Canadian Task Force on Preventive Health (CTFOPH), which recommend against annual screening of women ages 40-49 and would extend time between screens for older women.

MU researchers find synthetic RNA lessens severity of fatal disease

COLUMBIA, Mo. – A team of University of Missouri researchers have found that targeting a synthetic molecule to a specific gene could help the severity of the disease Spinal Muscular Atrophy (SMA) – the leading genetic cause of infantile death in the world.

Improved method of electrical stimulation could help treat damaged nerves

BOSTON – Functional electrical stimulation (FES) was developed to help return lost function to patients with upper and lower extremity injuries and spinal cord injuries, among other applications. However, the devices, which work by stimulating neuronal activity in nerve-damaged patients, have a potential shortcoming in that the electrical currents needed for the treatment to work can also send errant signals to surrounding nerves, resulting in painful side effects.

Chew gum, lose weight

Most people understand that serious weight loss requires changing attitudes toward what they eat and how often they exercise. But, what if the process could be aided by simply chewing a stick of gum after meals? That's the question a team of scientists, led by Syracuse University chemist Robert Doyle, is trying to answer. In a groundbreaking new study, Doyle's team demonstrated, for the first time, that a critical hormone that helps people feel "full" after eating can be delivered into the bloodstream orally.

Van Andel Institute study may lead to better, safer drug for diabetes

Grand Rapids, Mich. (November 21, 2011) A Van Andel Research Institute (VARI) study published recently in the Journal of Biological Chemistry reveals that a natural fatty acid can serve as a regulator of blood sugar levels, which may have important applications in designing better and safer drugs for diabetes treatment.

According to the U.S. Center for Disease Control and Prevention (CDC), nearly 26 million Americans have diabetes, and current drugs commonly used to treat the disease sometimes have unwanted side effects.

New projection shows global food demand doubling by 2050

Global food demand could double by 2050, according to a new projection by David Tilman, Regents Professor of Ecology in the University of Minnesota's College of Biological Sciences, and colleagues, including Jason Hill, assistant professor in the College of Food, Agricultural and Natural Resource Sciences.

Future prostate cancer treatments might be guided by math

COLUMBUS, Ohio – Scientists have designed a first draft of a mathematical model that someday could guide treatment decisions for advanced prostate cancer, in part by helping doctors predict how individual patients will respond to therapy based on the biology of their tumors.

Researchers shrink tumors and minimize side effects using tumor-homing peptide to deliver treatment

LA JOLLA, Calif., November 21, 2011 – The trouble with most anti-cancer therapies is that they are lethal to most cells in the body, not just cancer cells. As a result, patients experience side effects like nausea, increased susceptibility to infection, and increased risk of developing secondary cancers later in life. Researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) are developing techniques to deliver cancer drugs directly to tumors, increasing their effectiveness and decreasing collateral damage.
