By means of a microelectrode that measures the impedance and temperature of the tissues, the system enables the state of any organ to be monitored from the moment of its extraction, during its transport, to the moment of the surgical operation to transplant it into a patient.
The Ikerlan-IK4 device, designed in collaboration with the National Centre for Microtechnology (CNM-CSIC) and the Carburos Metálicos company and patented in conjunction with I2M Design S.A., uses a polymer substrate that represents a great advance in biomedical instrumentation, as it does not produce injury in the tissues during transport or surgical manoeuvres. It even opens a new way to control organ rejection, given that the microelectrode can remain implanted for a considerable time without causing injury.
The application has a number of prototypes already and has had clinical trials with organs of animals at Barcelona’s Hospital Clínic. Moreover, it is of particular interest for a process as delicate as an organ transplant, as it provides an objective indicator of the evolution of the organ in which, despite the conservation techniques used – whether with special liquids or in cold -, the duration of the viscera is highly limited (12 hours in the case of the kidney, eight for the liver and only four hours in the case of the heart). The device is used incorporated into a small electronic system which gathers and sends data by telemetry to an external system, enabling the verification of the state of the organ at all times.
Due to medical advances, the transplant of organs is an evermore common medical practice. Thanks to the high number of donors in the Basque Country, this country has one of the highest rates of transplants in the world, with 61 kidney transplants per million inhabitants in 2006; 26.3 liver transplants and 4.7 heart transplants.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
