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.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
