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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
