A drug used for the treatment of sickle cell anemia in adults has now been shown to cause significant improvements in very young children with the disorder. The finding is an important one as these young patients are especially vulnerable to serious organ failure and even death at an early age. The study results will be published in the October 1, 2005, issue of Blood, the official journal of the American Society of Hematology.
Sickle cell anemia is a genetic blood disorder that can cause severe pain, fatigue, and organ damage to the kidneys, spleen, and liver. It occurs in about one in every 500 African-Americans. In the new study, 21 children from two to four years old who had sickle cell anemia were given the drug hydroxyurea orally as a flavored liquid formula. A majority of the children took the drug for at least four years and more than half of the participants completed all six years of the study.
The treatment was well-tolerated in the patients, with only one childs dosage permanently reduced during the study due to adverse effects. The drugs primary function, to counteract the effects of the disease by increasing and sustaining fetal hemoglobin production, was achieved in all study participants. Patients treated with hydroxyurea also weighed more and were taller than untreated children with the disorder – their growth rates were even comparable to those of normal children.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
