Breast Imaging And Reporting Data Systems, And MRI In Predicting Breast Cancer: Study
Date: May-16-2012A large, multicenter study found that the Breast Imaging and Reporting Data Systems (BI-RADS) terminology used by radiologists to classify breast imaging results is useful in predicting malignancy in breast lesions detected with MRI. Results of the study are published online in the journal Radiology. "BI-RADS was developed to standardize the lexicon of breast imaging reports and to help ensure patients receive proper follow-up," said Mary C. Mahoney, M.D, director of breast imaging at the University of Cincinnati Medical Center in Ohio. "The BI-RADS lexicon for breast MRI provides descriptors...
Aortic Aneurysm Treatment Monitored By Contrast-Enhanced Ultrasound

Minimizing Stroke Damage
Date: May-16-2012Following a stroke, factors as varied as blood sugar, body temperature and position in bed can affect patient outcomes, Loyola University Medical Center researchers report. In a review article in the journal MedLink Neurology, first author Murray Flaster, MD, PhD and colleagues summarize the latest research on caring for ischemic stroke patients. (Most strokes are ischemic, meaning they are caused by blood clots.) "The period immediately following an acute ischemic stroke is a time of significant risk," the Loyola neurologists write. "Meticulous attention to the care of the stroke patient...
Religion Replenishes Self-Control
Date: May-16-2012There are many theories about why religion exists, most of them unproven. Now, in an article published in Psychological Science, a journal of the Association for Psychological Science, psychologist Kevin Rounding of Queen's University, Ontario, offers a new idea, and some preliminary evidence to back it up. The primary purpose of religious belief is to enhance the basic cognitive process of self-control, says Rounding, which in turn promotes any number of valuable social behaviors. He ran four experiments in which he primed volunteers to think about religious matters. Those volunteers showed...
Eye Cancer Tumors Likely To Spread Can Be Identified By Genetic Test
Date: May-16-2012Researchers at Washington University School of Medicine in St. Louis have developed a genetic test that can accurately predict whether the most common form of eye cancer will spread to other parts of the body, particularly the liver. In 459 patients with ocular melanoma at 12 centers in the United States and Canada, the researchers found the test could successfully classify tumors more than 97 percent of the time. The study will appear in an upcoming issue of the journal Ophthalmology, but is now online. "When the cancer spreads beyond the eye, it's unlikely any therapy is going to be...
Differences Seen In Brain Circuitry Between Women With Anorexia And Those With Obesity
Date: May-16-2012Why does one person become anorexic and another obese? A study recently published by a University of Colorado School of Medicine researcher shows that reward circuits in the brain are sensitized in anorexic women and desensitized in obese women. The findings also suggest that eating behavior is related to brain dopamine pathways involved in addictions. Guido Frank, MD, assistant professor director of the Developmental Brain Research Program at the CU School of Medicine and his colleagues used functional magnetic resonance imaging (fMRI) to examine brain activity in 63 women who were either...
Scientist Grows Bone From Human Embryonic Stem Cells
Date: May-16-2012Dr. Darja Marolt, an Investigator at The New York Stem Cell Foundation (NYSCF) Laboratory, is lead author on a study showing that human embryonic stem cells can be used to grow bone tissue grafts for use in research and potential therapeutic application. Dr. Marolt conducted this research as a post-doctoral NYSCF - Druckenmiller Fellow at Columbia University in the laboratory of Dr. Gordana Vunjak-Novakovic. The study is the first example of using bone cell progenitors derived from human embryonic stem cells to grow compact bone tissue in quantities large enough to repair centimeter-sized...
US Seniors Are Going Hungry
Date: May-16-2012A new study that looked at the hunger trends over a 10-year period found that 14.85 percent of seniors in the United States, more than one in seven, face the threat of hunger. This translates into 8.3 million seniors. "In 2005, we reported that one in nine seniors faced the threat of hunger," said Craig Gundersen, University of Illinois associate professor of agricultural and consumer economics and executive director of the National Soybean Research Laboratory who led the data analysis on the study. "So, unlike the population as a whole, food insecurity among those 60 and older actually...
Injuries With Baby Bottles, Pacifiers And Sippy Cups In The US And Related Treatment Required In An Emergency Department
Date: May-16-2012A new study by researchers in the Center for Biobehavioral Health and the Center for Injury Research and Policy at Nationwide Children's Hospital examined pediatric injuries associated with baby bottles, pacifiers and sippy cups. Researchers found that from 1991 to 2010, an estimated 45,398 children younger than three years of age were treated in U.S. emergency departments for injuries related to the use of these products. This equates to an average of 2,270 injuries per year, or one child treated in a hospital emergency department every four hours for these injuries. The study, which was...
Understanding The Cellular Secrets Of Plant Fatty Acid Production
Date: May-16-2012A curious twist in a family of plant proteins called chalcone-isomerase recently was discovered by Salk Institute for Biological Studies scientist Joseph Noel and colleagues at Iowa State University led by Eve Wurtele. Pursuing basic scientific discovery, they found three similar proteins that could soon translate into positive results for bio-renewable fuels, commodity chemicals like plastics, food security and nutrition and biomedicine. The findings, reported in advance online publication of the journal Nature, may lead to higher-yield crops and quantities of oils, help to address growing...
