Doctors in Brazil have concluded that the drug amifostine eases many of the most common side effects associated with patients receiving radiation therapy to treat their cancer while simultaneously making the cancer more susceptible to radiation. The study was published in the March 1, 2006, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.
The researchers set out to evaluate, via a clinical investigation of already published work, whether adding amifostine to radiation therapy would prevent common side effects, such as mouth dryness, difficulty swallowing, lung inflammation, bladder inflammation, problems with the esophagus and inflammation of the mucous membranes. In some cases, these side effects can be severe enough that the patients treatment has to be suspended or stopped completely – potentially preventing their cancer from being completely cured. The other major purpose of the study was to discover if amifostine would inadvertently protect the tumor from radiation.
The investigators narrowed their research to 14 randomized, controlled trials in which 1,451 patients were split into two groups: one receiving radiation therapy alone and the second receiving radiation therapy in addition to amifostine. Patients taking amifostine were shown to have less radiation-related side effects. The research also showed that the drug did not protect the tumor from the radiation therapy and patients receiving the drug were more likely to have their cancer affected by the radiation than patients not given amifostine.

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...
