Killing the disease without killing the patient is an old dilemma for doctors fighting cancer and some of the tougher microorganisms such as fungal infections in individuals with suppressed immune systems. Drugs have little effect when a patients own immune system isnt available to help, and these fungi can resist external radiation that would kill even a perfectly healthy human. But they can be easily killed by a very small dose of radiation inside their cells.
Monoclonal antibodies can be designed to deliver radiation to specific cell types while sparing surrounding tissue. These designer antibodies, armed with radioactive isotopes, have been found to be highly effective against some types of cancer, but the combination may also be useful in other types of serious disease. This technique is known as radioimmunotherapy (RIT).
A study appearing in the February issue of The Journal of Nuclear Medicine demonstrates that radioimmunotherapy (RIT) provides a new, highly effective way to kill Cryptococcus neoformans and Histoplasma capsulatum, the fungi responsible for fungal meningitis and pneumonia, using much smaller levels of radiation than required to kill the fungi by external radiation. The study used organism-specific monoclonal antibodies coupled with radioactive isotopes of bismuth or rhenium.

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...
