Using the perfusion image made by a laser and an ultra fast camera, doctors will be able to determine whether a burn needs surgery. The new measuring device, developed under supervision of dr. Wiendelt Steenbergen of the Biophysical Engineering group, has been successfully tested at the hospital Martini Ziekenhuis in Groningen.
Tests in hospital show that the system is perfectly capable of measuring differences in perfusion in burn wounds; patients and medical staff are positive about the high speed of the system and the quality of the images.
A burn that shows good perfusion, has a better chance of healing by itself: no surgery is needed. In many cases, the visual inspection is not sufficient to take a decision on the necessity of surgery. This can lead to unnecessary surgery or, on the other hand, to unwanted delays when surgery is the best option. Compared to current perfusion measurements, the new technique is much faster. Scanning techniques take minutes of time for some square centimeters of skin, during which time the patient is not allowed to move. The new technique will be capable of imaging an entire surface of ten by ten centimeter in a fraction of a second.Doppler effect
Apart from this promising application in determing perfusion in burn injuries, Wiendelt Steenbergen predicts other applications, for example in evaluating the uptake of medication through the skin, or in testing allergic reactions. In evaluating diabetic micro circulation problems, the new technique could be an attractively fast alternative to current approaches as well.

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...
