11.09.2019Researchers at KU Leuven in Belgium have developed a technique to make sheep produce new antibodies simply by injecting the DNA building blocks. This approach is much cheaper and more efficient than producing antibodies industrially and administering them afterwards. The study in animals with a similar size as humans brings us a step closer to the clinical use of antibody gene therapy.
06.09.2019Cardiovascular stents are special implants used to widen blood vessels that have become constricted as a result of calcium deposits. In some cases, the body's immune system can reject these implants in a process known as foreign-body reaction. In a joint project with partners, Fraunhofer researchers have now developed enhanced coatings that substantially improve the biocompatibility of stents.
30.08.2019In a study led by Harvard University's Kevin Kit Parker, microfluidics and human, insulin-producing beta cells have been integrated in an "Islet-on-a-Chip". The new device makes it easier for scientists to screen insulin-producing cells before transplanting them into a patient, test insulin-stimulating compounds, and study the fundamental biology of diabetes.
21.08.2019Researchers on ageing from the Max Planck Institute for Biology of Ageing and the Leiden University Medical Center (LUMC) collaborate to link basic insights from model organisms to the causes of ageing in humans. They can determine the disease vulnerability of older people using a defined set of substances in the blood.

21.11.2018Our blood reveals a lot about our physical health. The shape of our blood cells sheds light on several hereditary diseases for example. For a diagnosis, the cells must first be examined under the microscope and categorized into a specific cell class. We met with Dr. Stephan Quint and Alexander Kihm of the Institute of Physics at the Saarland University, who explained how this classification works.
02.11.2018This is what diagnostic investigation normally looks like: a patient sample is collected, sent to the laboratory and analyzed. Once that's completed, the patient is told of the lab test result. But if the patient is a high-performance athlete and has to follow and stick to a rigid training schedule, he or she needs these results immediately. What makes this possible? Point-of-care testing!
22.06.2018A drop of blood provides a lot of valuable information. However, it takes several hours to analyze the blood of a patient and make a diagnosis. This takes away a lot of time that's crucial for treatment. A new method intends to considerably speed up this process by testing the cells in the blood in terms of their deformability and immune response.
20.12.2017Sixty percent of newborns are affected by jaundice during their first days of life. In most cases, the condition is harmless. The ailment is more pronounced in premature babies, whose treatment involves irradiation with blue light in a special incubator – naked and alone.
01.08.2017Advances in technology and analysis techniques, as well as the increasing miniaturization of laboratory equipment and processes, make it possible: patient-side laboratory testing, better known as point-of-care testing or POCT. There are many POCT projects and all of them promise a rapid diagnosis as well as economic advantages. But are these tests also suited for everyday medical testing?
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.
24.07.2017A new analysis method that uses fetal DNA extracted from the mother’s blood is designed to non-invasively reach a prenatal diagnosis of genetic disorders in a child.
