Research has shown that the drug tamoxifen citrate not only helps prevent recurrence of breast cancer, but it also can keep the deadly disease from occurring in the first place in some women.
But a new University of North Carolina at Chapel Hill study indicates its unlikely that tamoxifen will ever be given widely to women to prevent breast cancer. Thats because the drug would avert only a maximum of 6 percent to 8.3 percent of breast tumors in eligible women, UNC School of Medicine researchers have found. "Our calculations showed that tamoxifens possibly harmful side effects, including blood clots and stroke, would rule out some 90 percent of women who might benefit from taking it each day," said Dr. Russell P Harris, associate professor of medicine at UNC. A report on the study appears in the latest issue of the Archives of Internal Medicine.
Besides Harris, a member of UNCs Lineberger Comprehensive Cancer Center, authors are principal investigator Dr. Carmen L. Lewis, assistant professor of medicine at UNC; Dr. Linda S. Kinsinger, assistant director of the VA Center for Health Promotion and Disease Prevention; and Robert J. Schwartz, a computer programmer at UNCs Cecil G. Sheps Center for Health Services Research.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
