Barrett's epithelium is recognized as a complication of erosive esophagitis and is the pre-malignant condition for adenocarcinoma of the esophagus.
A research team from Yokohama City University School of Medicine hypothesized that some macroscopic features of Barrett's epithelium might be useful for identifying a subgroup with a high risk for the development of esophageal adenocarcinoma. Their study will be published on January 28, 2010 in the World Journal of Gastroenterology.
Monash University biochemists have found a critical piece in the evolutionary puzzle that explains how life on Earth evolved millions of centuries ago.
The team, from the School of Biomedical Sciences, has described the process by which bacteria developed into more complex cells and found this crucial step happened much earlier in the evolutionary timeline than previously thought.
CHICAGO, Ill. (February 5, 2010) — In a study to be presented today at the Society for Maternal-Fetal Medicine's (SMFM) annual meeting, The Pregnancy Meeting ™, in Chicago, researchers will unveil findings that demonstrate a link between the birth defect gastroschisis and the agricultural chemical atrazine.
CHICAGO, Ill. (February 5, 2010) — In a study to be presented today at the Society for Maternal-Fetal Medicine's (SMFM) annual meeting, The Pregnancy Meeting ™, in Chicago, researchers will unveil findings that show that it is not cost effective to screen for spinal muscular atrophy.
Children who are especially reactive to stress are more vulnerable to adversity and have more behavior and health problems than their peers. But a new longitudinal study suggests that highly reactive children are also more likely to do well when they're raised in supportive environments.
The study, by scientists at the University of British Columbia, the University of California, San Francisco, and the University of California, Berkeley, appears in the January/February 2010 issue of the journal Child Development.
Researchers at Yale School of Medicine believe they may have discovered how the hormone progesterone acts to prevent preterm birth.
The findings will be presented at the Annual Scientific Meeting of the Society for Maternal-Fetal Medicine (SMFM) in Chicago by Errol Norwitz, M.D., professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale.
Bacteria that infect chronic wounds can be deadly to maggot 'biosurgeons' used to treat the lesions, show researchers writing in the journal Microbiology. The findings could lead to more effective treatment of wounds and the development of novel antibiotics.
Scientists from the Copenhagen Wound Healing Centre, Statens Serum Institut and the University of Copenhagen in Denmark showed that maggots applied to simulated wounds heavily infected with the bacterium Pseudomonas aeruginosa, were unable to treat the wound and were left dead after 20 hours.
The American Society for Radiation Oncology (ASTRO) and the American College of Radiology (ACR) have released practice guidelines for image guided radiation therapy (IGRT) and stereotactic body radiation therapy (SBRT) in the February issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO.
These guidelines were released as educational tools to assist practitioners in providing appropriate, effective and safe medical care for patients.
NORFOLK, Va. – Doctors at Eastern Virginia Medical School's Strelitz Diabetes Center have been stalking the culprit responsible for Type 1 diabetes. Now, they are one step closer.
Members of a research team at the center, led by Jerry Nadler, MD, professor and chair of internal medicine and director of the center, have been studying the role of the enzyme 12-Lipoxygenase (12-LO) in the development of Type 1 diabetes. They hope that targeting this enzyme will hold the key to a cure.
TALLAHASSEE, Fla.--In the natural stream communities of Trinidad, guppy populations live close together, but evolve differently. Upstream, fewer predators mean more guppies but less food for each; they grow slowly and larger, reproduce later and less, and die older. Downstream, where predators thrive, guppies eat more, grow rapidly, stay small, reproduce quickly and die younger.
Ancient human teeth are telling secrets that may relate to modern-day health: Some stressful events that occurred early in development are linked to shorter life spans.
"Prehistoric remains are providing strong, physical evidence that people who acquired tooth enamel defects while in the womb or early childhood tended to die earlier, even if they survived to adulthood," says Emory University anthropologist George Armelagos.
COLLEGE PARK, Md. -- New research conducted at the University of Maryland's bat lab shows Egyptian fruit bats find a target by NOT aiming their guiding sonar directly at it. Instead, they alternately point the sound beam to either side of the target. The new findings by researchers from Maryland and the Weizmann Institute of Science in Israel suggest that this strategy optimizes the bats' ability to pinpoint the location of a target, but also makes it harder for them to detect a target in the first place.
Auckland, New Zealand and Chicago, USA -- February 4, 2010 -- Giving smokers information about their own individual risk of serious illness helps motivate them to quit smoking, according to a paper published in the current issue of Postgraduate Medical Journal.
SAN ANTONIO, Texas, U.S.A. (Feb. 4, 2010) — A new finding described today by teams from the National Cancer Institute, The University of Texas Health Science Center at San Antonio and the University of Toronto offers a clue as to how genes can have what you might call multiple personalities.
The best way to track a moving object with a flashlight might be to aim it to one side, catching the object in the edge of the beam rather than the center. New research at the Weizmann Institute of Science reveals that bats, which 'see' with beams of sound waves, skew their beams off-center when they want to locate an object. The research, which recently appeared in Science, shows that this strategy is the most efficient for locating objects.
