MRI can determine if a patient has endometrial versus cervical cancer even when a biopsy can't make that distinction, according to a new study. Determining the primary site of a tumor helps determine appropriate cancer treatment.
The study, which is being presented during the American Roentgen Ray Society Annual Meeting on May 3 in Chicago, found that radiologists using MRI could correctly identify the primary site of cancer in 79% of cases (38/48 patients) when biopsy results are inconclusive.
BIRMINGHAM, Ala. – An antioxidant may prevent damage to the liver caused by excessive alcohol, according to new research from the University of Alabama at Birmingham. The findings, published online April 21, 2011, in the journal Hepatology, may point the way to treatments to reverse steatosis, or fatty deposits in the liver that can lead to cirrhosis and cancer.
ST. PAUL, Minn. – According to a new study, being overweight or obese during middle age may increase the risk of certain dementias. The research is published in the May 3, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology.
ROCHESTER, Minn. - One of the largest studies of its kind has found that people with coronary artery disease who have even a modest beer belly or muffin top are at higher risk for death than people whose fat collects elsewhere. The effect was observed even in patients with a normal Body Mass Index (BMI). The findings of this Mayo Clinic analysis are published in the May 10 issue of the Journal of the American College of Cardiology.
Doctors should consider using catheterization as a treatment tool in addition to its established role in diagnosing children with heart defects, according to a new American Heart Association scientific statement.
A catheter is a thin flexible tube inserted into a blood vessel and used in procedures such as angiography, in which physicians use the catheter to inject dye into the arteries near the heart to illuminate the vessels via X-ray technology. It can also open a valve, enlarge a narrow blood vessel, close a hole in the heart or close off a blood vessel.
A study documents reduction in hospital mortality over ten years in a children's hospital without a Pediatric Emergency Medical Team (PMET), according to a report in the May issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
Among children whose parents and other primary caregivers have limited English proficiency, there is an associated increased length of hospital stay and decreased number of home health care referrals for pediatric inpatients with infections requiring long-term antibiotics, according to a report in the May issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
People who wash their hands with contaminated soap from bulk-soap-refillable dispensers can increase the number of disease-causing microbes on their hands and may play a role in transmission of bacteria in public settings according to research published in the May issue of the journal Applied and Environmental Microbiology.
SALT LAKE CITY, May 2, 2011 –- For decades, a 2.3 million- to 1.2 million-year-old human relative named Paranthropus boisei has been nicknamed Nutcracker Man because of his big, flat molar teeth and thick, powerful jaw. But a definitive new University of Utah study shows that Nutcracker Man didn't eat nuts, but instead chewed grasses and possibly sedges –- a discovery that upsets conventional wisdom about early humanity's diet.
Using museum specimens from Mexico, Guatemala and Costa Rica, a team of researchers from San Francisco State University and University of California at Berkeley has documented evidence of a Batrachochytrium dendrobatidis (Bd) epidemic wave that wiped out native amphibians, according to research to be published on May 3 by the Proceedings of the National Academy of Sciences. (PNAS).
In modern ecology, the removal or addition of a predator to an ecosystem can produce dramatic changes in the population of prey species. For the first time, scientists have observed the same dynamics in the fossil record, thanks to a mass extinction that decimated ocean life 360 million years ago.
A team of researchers has identified a cellular protein that acts as a receptor for Ebola virus and Marburg virus. Furthermore, the team showed that an antibody, which binds to the receptor protein, is able to block infection by both viruses.
An ancient, bipedal hominid sporting a set of powerful jaws and huge molars that earned it the nickname "Nutcracker Man" likely didn't crack nuts at all, preferring instead to slurp up vast quantities of grasses and sedges, says a new study.
On land, being small and lurking at the bottom of the food chain is a far better strategy for species survival than being big, fierce and perched on top, at least when humans are after you – just ask the mice and grizzly bears.
But talk to sharks and anchovies and they'll tell you a different story, according to a new study of fisheries collapses led by Stanford researchers.
There's a crisis among the world's amphibians—about 40 percent of amphibian species have dwindled in numbers in just three decades. Now, museum jars stuffed full of amphibians may help scientists decide whether this wave of extinctions was caused by a fungal infection.
