An enzyme that protects the body from reactive chemicals called free radicals is crucial in preventing the inflammation that causes chronic lung disease in premature infants, according to three new studies.
The findings could lead to improved treatments to alleviate such inflammation, preserving the lungs of premature infants, said Richard Auten, M.D., a neonatalogist and associate professor of pediatrics at Duke University Medical Center. Auten and colleagues from the Medical College of Wisconsin reported their findings in three presentations on May 2 and 3, 2004, at the Pediatric Academic Societies’ annual meeting in San Francisco. The research was sponsored by the American Lung Association and the National Institutes of Health.
In studies with mice, the researchers previously found that infant animals with an extra copy of the gene for the crucial enzyme, called superoxide dismutase, were better able to defend themselves against oxygen-free radicals. Oxygen-free radicals are highly reactive forms of oxygen that can readily combine with and damage proteins and other molecules in body tissues such as the lungs. Superoxide dismutase reacts with oxygen-free radicals, converting them into harmless byproducts.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
