Novel drug increases survival in animal models exposed to high-dose radiation

A novel drug that mimics a naturally occurring molecule found in coffee and blueberries has been developed to treat radiation exposure. Charles R. Yates, Pharm.D., Ph.D., and colleagues Duane Miller, Ph.D., and Waleed Gaber, Ph.D., from the University of Tennessee Health Science Center and Baylor College of Medicine, show that application of this drug, starting 24 hours after radiation exposure, increases survival in animal models by three-fold compared to placebo.

AIUM to host Ultrasound First Forum on Nov. 12

The American Institute of Ultrasound in Medicine (AIUM) will host an Ultrasound First Forum on November 12, 2012, in New York, New York. The forum will address the expanding role of ultrasound imaging as a "first" imaging examination and will be devoted to encouraging the use of ultrasound as a safe, effective, and affordable alternative to other diagnostic imaging modalities where scientific evidence supports its appropriateness.

NVIDIA video cards can help reduce radiation exposure from X-ray and CT scans

Video gamers are generally the biggest consumers of computer graphics cards, using the devices to boost the speed and resolution of their digital quests to fend off invading extraterrestrials or outwit hostile dragons. But researchers at Rensselaer Polytechnic Institute seek to harness the power of these computer graphics cards to solve one of the world's most pressing health care technology challenges: radiation exposure from X-ray and CT imaging scans.

Regional PACS networks may be useful in reducing cost and radiation exposure associated with trauma

According to a study in the Sept. issue of the Journal of the American College of Radiology, using a combination of the Internet and compact discs (CD) to transfer images during inter-hospital transfer is associated with much lower repeat imaging rates, suggesting that regional PACS networks may be useful for reducing cost and radiation exposure associated with trauma.

Ultra-fast 320-detector CT scanner can accurately diagnose arterial blockages

An ultra-fast, 320-detector computed tomography (CT) scanner can accurately sort out which people with chest pain need - or don't need - an invasive procedure such as cardiac angioplasty or bypass surgery to restore blood flow to the heart, according to an international study. Results of the study, which involved 381 patients at 16 hospitals in eight countries, are scheduled to be presented at the European Society of Cardiology Congress in Munich, Germany, on August 28.

Two studies examine psychological status of Fukushima workers after nuclear plant disaster

The results of two studies in the August 15 issue of JAMA report on the psychological status of workers at the Fukushima nuclear power plants in Japan several months after the earthquake and tsunami in March 2011, and the amount of internal radiation exposure among residents of a city north of the power plant that experienced a meltdown.

Young women with indoor tanning habits frequently experience sunburn

Controversy remains over the risks involved with indoor tanning, especially in children and young adults. Since sunburn serves as a marker for excessive and skin-cell damaging ultraviolet (UV) exposure -- which can eventually lead to the development of skin cancer -- investigators at The Cancer Institute of New Jersey (CINJ) took a closer look at a college-aged sample of females and their indoor tanning habits.
