18/09/2018Prof. Johannes Herrmann, a researcher at the Technische Universität Kaiserslautern, and his team discovered a novel mechanism by which newly synthesized proteins reach their respective target compartment in the cell. Proteins destined to mitochondria, are not directly transported to mitochondria but are directed to the surface of the endoplasmic reticulum.
18/09/2018Scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) have identified new means of fighting drug-tolerant bacteria, a growing global threat as menacing as drug-resistant microbes. Little is known about the mechanisms leading to tolerance, a strategy that makes bacteria "indifferent" to antibiotics and almost "un-killable," which results in chronic infections.
29/08/2018Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart -- a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death.
22/08/2018A new biosensor allows researchers to track oxygen levels in real time in "organ-on-a-chip" systems, making it possible to ensure that such systems more closely mimic the function of real organs. This is essential if organs-on-a-chip hope to achieve their potential in applications such as drug and toxicity testing.
09/07/2018People who are not ill and do not show any symptoms typically do not visit the doctor. And while most people know that preventive medical checkups for cancer, for example, are important, they still avoid them. They tend to be very hesitant because the doctor might detect a serious illness. In the future, a new type of implant could make it easier to go to a screening test.
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.
23/04/2018A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.
01/03/2018Everyone is different. This statement also applies to our health. Cancer, in particular, can look and progress differently depending on the individual person. That’s why every patient ideally also needs a customized treatment that is tailored to their individual needs. But how feasible is this idea?
22/02/2018Here on Earth, all experiments are bound by gravitation. Yet, freed from gravity's grip, tumor cells, for example, behave in an entirely different way. As part of the "Thyroid Cancer Cells in Space" project by the University of Magdeburg, smartphone-sized containers carrying poorly differentiated thyroid cancer cells are sent into space.
08/01/2018Few patients with heart failure are fortunate enough to receive a donor's heart. Ventricular assist devices (or heart pumps) have been around for several years and are designed to buy time as patients wait for a transplant. Unfortunately, the body doesn't always tolerate these devices.
22/08/2017Physics has always supported medical science, especially when it comes to practical implementation. 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.
22/07/2016Millions of people all over the world suffer from partial blindness – caused by glaucoma, a stroke or traumatic brain injury. For years, the loss of vision was deemed irreversible. But now a new treatment makes it possible to improve eyesight and vision.
09/02/2016Many people suffer from atherosclerosis, especially in developed countries. The buildup of fatty deposits inside the arterial blood vessels leads to strokes and heart attacks. Now, a new method is designed to get to the root of the problem, and with the help of nanoparticles inject new turbo replacement cells into the blood vessels which are intended to exert their curative effect.
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.
01/02/2016Self-healing powers like a superhero on the big screen? That’s the aim of regenerative medicine; at least in a very broad sense. This promising field of biomedicine is currently highly dynamic with innovative technologies and development. New methods are designed to help propel medicine into a whole new sphere.
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. It is believed that the T-cells in persons who are affected by inflammatory bowel disease don’t work properly. Two proteins that can be found on activated T-cells and that interact with each other are now being analyzed.
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.
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.
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. In cooperation with the University of Rostock (Professor Hermann Seitz), the human med AG Company currently seeks to develop a device that is able to gently remove adipose tissue during surgery and subsequently isolate stem cells.
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.
