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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
