A study that includes 20 years of follow-up does not support aggressive treatment for localized, low-grade prostate cancer, with data indicating a small risk of progression of this grade of cancer, according to a study in the May 4 issue of JAMA.
To determine the need for treatment of localized prostate cancer, patients and physicians must understand the natural history of this disease, according to background information in the article. A recent study suggested an increasing prostate cancer death rate for men who are alive more than 15 years following diagnosis. The appropriate therapy for men with clinically localized prostate cancer has been uncertain.
Peter C. Albertsen, M.D., M.S., of the University of Connecticut Health Center, Farmington, Conn., and colleagues conducted a study to determine whether prostate cancer death rates declined, remained constant, or increased after 15 years. The researchers used data from the Connecticut Tumor Registry, supplemented by hospital record and histology review of 767 men aged 55 to 74 years with clinically localized prostate cancer diagnosed between January 1, 1971, and December 31, 1984. Patients were treated with either observation or immediate or delayed androgen withdrawal therapy, with an observation period of 24 years being the norm.

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...
