Gene expression profiling can help doctors accurately identify subtypes of pediatric acute lymphoblastic leukemia (ALL), according to the October 15, 2003, issue of Blood, the official journal of the American Society of Hematology. Diagnosing a subtype of ALL can allow physicians to customize a treatment program based on a patients likelihood of responding to therapy.
Pediatric acute lymphoblastic leukemia has a number of subtypes, each with unique cellular and molecular characteristics. Since the subtype may also imply a less favorable prognosis, it is critical to diagnose each individual patients subtype so that therapy can be tailored to reduce the chance of a relapse. ALL patients currently have a 70 to 80 percent chance of surviving the disease, but the odds of survival decrease following a relapse.
ALL subtypes are used to assign patients to risk groups. Risk group assignment is an important element of cancer care because it allows physicians to avoid overtreating patients who are at low risk of relapse, while ensuring optimal treatment for patients with a high risk of relapse. Patients are currently classified into risk groups based on factors such as age and gender, white blood cell count, the presence or absence of leukemia in cerebral spinal fluid, and genetic characteristics of the leukemic cells. These risk features were identified from epidemiological studies and have resulted in excellent overall long-term survival rates, but gene expression profiling may provide an even more precise profile of a patients disease.

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...
