A new study finds tobacco may act as an environmental trigger for patients with an inherited genetic predisposition to pancreatic cancer. The authors of the report say the findings underscore the importance of strongly counseling patients with a family history of pancreatic cancer to avoid smoking. The study will be published in the December 15, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of this study will be available via the CANCER News Room upon online publication.
Pancreatic cancer is rare and poorly studied. What is known is that pancreatic cancer is aggressive, with a five-year survival rate of only 4 percent. A small percentage of patients with pancreatic cancer have first-degree relatives with pancreatic cancer. Smoking has been identified as the single most important risk factor in familial pancreatic cancer. Despite genetic characterization of other hereditary cancers, the genetic component of pancreatic cancer remains a mystery. With such little known about what is now called familial pancreatic adenocarcinoma (FPAC), researchers led by Ted A. James, M.D. of the Roswell Park Cancer Institute in Buffalo, New York investigated the clinical course and outcome of FPAC compared to sporadic pancreatic cancer.
Retrospective review of 826 patients with pancreatic cancer found 30 had the familial form (3.6 percent). Earlier age at diagnosis and a smoking history were marked features among the familial group. The mean age of diagnosis was younger in the hereditary cohort than among those with the sporadic form (57.1 years old versus 61 years old), and more FPAC patients were diagnosed before the age of 50 (36.7 percent versus 18.3 percent). Moreover, patients with FPAC were more likely to smoke than those who had sporadic pancreatic cancer (87 percent versus 66 percent).

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...
