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 recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
