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.

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.

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.

He told MEDICA.de which technology is behind all this and what he also wants to examine with it in the future.
03/02/2014Differentiating tumor tissue from healthy tissue isn’t always easy for surgeons. Scattered cancer cells and early cancer are often hard to detect with the naked eye. A special camera now makes even the tiniest remainder of a tumor visible during surgery.
22/01/2014It guards the body but can become its enemy: the immune system defends us from intruding pathogens; it is also able to cause severe diseases if it falsely recognizes the body itself as a threat. Molecular receptors in the whole body enable the immune system to “sense” what happens within.
