A team of researchers from the University Hospital of Grenoble (CHU – Inserm U647) and the ESRF1 has found a new treatment that improves the survival of rats with high-grade gliomas.
This research was carried out at the ESRF Medical Beamline. It showed that after a year of this treatment, three rats out of 10 were considered cured, whereas without treatment, all would be dead. The results have just been published in the scientific journal Cancer Research. A glioma is one of the most frequent brain tumours in human adults, and it is not curable. Clinical trials on humans are planned for the near future.
Today, the median survival for patients with glioma is less than a year. Around 5 to 10 adults out of 100.000 suffer from this brain tumour. Traditional radiotherapy using hospital X-rays only has a palliative effect because gliomas are some of the most radio-resistant human tumours. Chemotherapy is ineffective most of the time. Several therapeutic techniques have been developed over the last years using animal models, but none has had such successful results as this new treatment with cis-platinum combined with monochromatic synchrotron x-rays. This new technique combines chemotherapy with radiotherapy in such a way that both techniques are effective when associated.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
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...
