15/03/2018A newly-discovered hereditary mutation is responsible for an increased production of erythropoietin (EPO) in the blood. This mutation causes a messenger RNA (mRNA) that is not normally involved in the formation of proteins to be reprogrammed so that it produces EPO, thus abnormally increasing the number of red blood cells.

Now physicists and health professionals join in collaborative research at an interdisciplinary Center in Erlangen and incorporate fundamental principles of theoretical physics in their studies of diseases.
01/08/2017Many therapeutic drugs are very powerful, but they are also very toxic at the same time. Thus, they have to be measured regularly, again and again, so that an adjustment of the individual drug dosage can be made. Until now, the "normal" way was to take the blood sample, send it to a central laboratory and get the results after some days. A new point-of-care test can measure it in 15 minutes.
03/07/2017Precision work is absolutely essential in eye surgery since the surgical site is very minute and sensitive. This is why eye surgeons have been using lasers for years. Femtosecond lasers are especially well suited to serve this purpose because they are able to cut tissue with great precision and little energy, which prevents unwanted side effects of surgery.
08/12/2016Watching millions of neurons in the brain interacting with each other – for a long time this was possible only to a limited extent. The current techniques can visualize only superficial layers or the imaging they use is too slow. But now, Prof Daniel Razansky and his team have found a new method to visualize the brain activity – by using optoacoustics.
08/08/2016What happens when stem cells differentiate? What molecular characteristics do they have? Questions that can now be easier answered with the help of a new open-source software. We spoke with Prof. Fabian Theis at the Helmholtz Center Munich, who participated in the software development.

01/02/2016Children, especially newborns, are generally no longer simply considered to be small adults whose treatment just needs to be "reduced". This is why a pediatrician’s education includes several specialties because ultimately everything in terms of care comes together here.
01/10/2015Semiconductor nanoparticles for biomedical applications have been researched for some time now. Not only are they millionths of a millimeter in size, they also offer great potential for cancer diagnostics and therapy, so-called theranostics. They enter cells, are activated by ultrasonic radiation and destroy the cells using the generated vibration.
02/03/2015Crises come in many shapes and sizes. Whether it’s poor hygiene, thefts or treatment errors – once the crisis has arrived, things need to move quickly. For hospitals in particular, the right crisis communication is key. Yet many medical facilities still neglect the fact that crisis communication starts before the actual crisis takes place.
02/02/2015The digitization of medicine moves on. Researchers, physicians and patients equally benefit from this development – thanks to improved diagnostics with highly sensitive devices, today findings can be comprehensively analyzed and treatment decisions made on a broadened basis. Digitization also offers the area of pathology interesting fields of application.
05/01/2015T-cells are the guardians of our immune system. When they show changes, it can lead to severe inflammatory responses in the body.

Two proteins that can be found on activated T-cells and that interact with each other are now being analyzed.
03/11/2014The treatment of chronic wounds is extremely problematic. Chronic wounds can take months or years to heal and some even never heal resulting in over 100.000 amputations taking place annually in the US alone. A new technology from Iceland, that is based on fish skin and is already used clinically, allows for improved healing of chronic and burn wounds.
03/11/2014As an imaging procedure, magnetic resonance tomography has become essential in clinical practice, since it can easily make organs and tissue visible. However, until now abnormal cancer cells or small centers of inflammation remained almost invisible. Now cell biologists from Berlin, Germany, have succeeded in fixing this problem with xenon magnetic resonance imaging.
01/10/2014On November 10, 2014, astronaut Alexander Gerst will return to Earth from the International Space Station (ISS). He is not just anxiously expected by his family, but also by Dr. Anna-Maria Liphardt from the Institute of Biomechanics and Orthopedics at the German Sport University Cologne
01/07/2014Large burns require skin grafting. Surgeons remove split-thickness skin grafts and apply them to the injured areas. Now skin that has been made in a laboratory is meant to help in covering burns as well as chronic wounds and thus promote the healing process. Researchers in Zurich have been working on this for more than 13 years.
01/07/2014In patients with Parkinson's, neural cells in the brain die off that produce the neurotransmitter dopamine. Certain physical symptoms that can indicate the disease follow years later. But a reliable diagnosis can only be made through examination of the brain after the patient's death, and not during his lifetime.
01/07/2014The not so popular “love handles“ could revolutionize medicine in the near future.
