A team from The University of Texas at Arlington has used mathematical modeling to develop a computer simulation they hope will one day improve the treatment of dangerous reactions to medical implants such as stents, catheters and artificial joints.

The work resulted from a National Institutes of Health-funded collaboration by research groups headed by Liping Tang, professor of bioengineering in the

LOS ANGELES (Sept. 24, 2013) – A new study of patients who died of sudden cardiac arrest, a usually fatal condition that causes the heart to stop beating, shows the majority who qualified to receive potentially lifesaving treatment did not receive it.

ROCHESTER, Minn. -- Sulfasalazine, a drug commonly prescribed to reduce diarrhea in patients with inflammatory bowel disease, does not reduce diarrhea in patients receiving radiation therapy for cancers in the pelvic area a Mayo Clinic-led study has found. The study also found that the medication may be associated with a higher risk of diarrhea than a placebo when used during radiation therapy to the pelvis. The results were presented today at the American Society of Radiation Oncology's (ASTRO's) 55th Annual Meeting in Atlanta.

Abraham and other cardiovascular researchers at 11 centers around the world tested the feasibility, safety and efficacy of a new transvenous phrenic nerve stimulator made by Respicardia Inc. The device resembles a pacemaker in that it delivers a regular signal to stimulate the diaphragm to breathe during sleep.

Pediatric researchers have found race- and ethnicity-based disparities in pain management and length of stay among children who came to hospital emergency departments for treatment of abdominal pain. A study team reported on their analysis of a national database of hospital visits in the October issue of Pediatrics.

Medicare expenses for patients with acute myocardial infarction (AMI, heart attack) increased substantially between 1998 and 2008, with much of the increase coming in expenses 31 days or more after the patient was hospitalized, according to a study published by JAMA Internal Medicine, a JAMA Network publication.

Researchers examined Medicare expenses for AMI in part because of large budget deficits in the United States and the high cost of caring for Medicare beneficiaries, according to the study background.

BOSTON – Nursing home residents with advanced dementia commonly experience burdensome, costly interventions that do not improve their quality of life or extend their survival. Now a new study suggests that providing intensive primary care services may result in less burdensome and less costly care for these terminally ill residents.

WASHINGTON, Sept. 23, 2013 – Audio CDs, all the rage in the '90s, seem increasingly obsolete in a world of MP3 files and iPods, leaving many music lovers with the question of what to do with their extensive compact disk collections. While you could turn your old disks into a work of avant-garde art, researchers in Taiwan have come up with a more practical application: breaking down sewage.

(SACRAMENTO, Calif.) — A scientific survey of gun dealers and pawnbrokers in 43 U.S. states has found nearly unanimous support for denying gun purchases based on prior convictions and for serious mental illness with a history of violence or alcohol or drug abuse – conditions that might have prevented Washington Navy Yard shooter Aaron Alexis from legally purchasing a firearm.

The research, conducted by the UC Davis Violence Prevention Research Program, is to be published in the Journal of Urban Health.

The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence of complex states in the ancient world.

When it comes to addressing the obesity epidemic, fast food restaurants are a favorite target, with some communities, such as the city of Los Angeles, going so far as to ban the construction of new, standalone fast food restaurants in neighborhoods with a high density of fast food restaurants that are also plagued by a high obesity rate.

Investments in green energy, education, networking opportunities and research top a list of 10 priorities for countries looking to move up the world's financial ranks, according to a leading US expert in innovation, creativity, entrepreneurship and economic growth.

Jerry Hultin, Senior Presidential Fellow of New York University, and President Emeritus of the Polytechnic Institute of NYU, says investments in life-long education and entrepreneurial spirit are the primary keys to a country's economic breakthrough.

It's not the chicken or the egg, but marine scientists at The University of Texas at Austin have answered a basic question about red drum fish and their eggs that may eventually help save the state of Texas a great deal of money in hatcheries management and make fish farming more environmentally friendly.

The threat from a heart attack doesn't end with the event itself. Blockage of blood flow to the heart can cause irreversible cell death and scarring. With transplants scarce, half the people who live through a heart attack die within five years. Scientists are trying to address this problem by engineering cardiac tissue to patch up damaged areas.

Atlanta, September 23, 2013 – A shorter course of androgen suppression therapy prior to radiation therapy, when compared to a longer course of androgen suppression therapy, yields favorable outcomes and fewer adverse effects for intermediate-risk prostate cancer patients, according to research presented today at the American Society for Radiation Oncology's (ASTRO) 55th Annual Meeting. The study confirmed a disease-specific-survival (DSS) rate of 95 percent when patients received fewer weeks of neoadjuvant (NEO) total androgen suppression (TAS).
