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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
