Researchers from the University of Chicago and Stanford University found that one of the new programs to increase the number of kidneys available for transplantation has disadvantages for candidates with blood type O who are waiting for an organ from a deceased donor. The researchers findings appear in the Sept. 15, 2004, issue of Transplantation.
Through a process called list-paired exchange, a person waiting for a kidney transplant gets a higher priority on the wait list for an organ from a deceased donor when a relative makes a living donation to another waiting recipient. The living donor is not able to donate to his or her relative, usually because of blood type incompatibilities, so the willing donor gives his or her kidney to an unknown person on the wait list.
The researchers argue that list-paired exchanges are unethical because they harm an already vulnerable population. The majority of candidates waiting for kidneys have blood type O. They have the longest wait times. Where list-paired exchanges are permitted, the researchers show, wait-list candidates of blood type O are forced to wait even longer for an available deceased donor kidney.

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...
