The University Hospital at Navarre University has developed a system for the percutaneous implantation of palladium 103 seeds, a new technique in permanent bradytherapy for the treatment of lung cancer. Recently, the fourth experiment was carried out and the results remitted to the scientific magazine, "Bradytherapy", for its publication. To date there has been no description in world scientific literature of any case using this therapeutic procedure.
The Clínica Universitaria has hosted the only cases of bradytherapy using palladium implantation although, in the literature, there exist two articles on the treatment of 8 patients with iodine 125, a radioisotope especially suited to treatment of prostate cancer. In this case it was decided to opt for palladium 103 given that theoretically it adapts better to rapid and aggressive growth lesions such as the majority of primary lung tumours – although this affirmation is not backed up by clinical data. Apart from this, the isotope having a shorter half-life, the radiological protection measures are reduced.
Bradytherapy is a radical radiation technique which is undertaken jointly by the Radiology and Oncology Departments at the University Hospital. It involves the percutaneous implantation of radioactive seeds by means of vectors that are placed inside the tumour. The procedure is carried out under a general anaesthetic with the patient lying on their back. First, the radiologist selects the target area and then the vectors are introduced with the point guided by CAT (computer-controlled axial tomography); in this way the structures through which they pass can be seen in practically real time. Once it is confirmed that the vectors are correctly placed into position, the radioactive load is impanted.

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....

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...
