18.06.2019Researchers at Ben-Gurion University of the Negev (BGU) and Cedars-Sinai Medical Center in Los Angeles have, for the first time, duplicated a patient's blood-brain barrier (BBB), creating a human BBB chip with stem cells, which can be used to develop personalized medicine and new techniques to research brain disorders.
17.06.2019Like airport security barriers that either clear authorized travelers or block unauthorized travelers and their luggage from accessing central operation areas, the blood-brain-barrier (BBB) tightly controls the transport of essential nutrients and energy metabolites into the brain and staves off unwanted substances circulating in the blood stream.
12.06.2019Machine learning has the potential to vastly advance medical imaging, particularly computerized tomography (CT) scanning, by reducing radiation exposure and improving image quality. Those new research findings were just published in Nature Machine Intelligence by engineers at Rensselaer Polytechnic Institute and radiologists at Massachusetts General Hospital and Harvard Medical School.
10.06.2019Cysts in the pancreas sometimes develop into the invasive cancer, depending on the type of cyst, but such growths often are not cancerous, creating a quandary for physicians who spot them via CT and MRI scans. Surgery to remove pancreatic cysts is often complex, so there is a need for new tools to identify which such cysts are most likely to develop into cancer and which are not.
04.06.2019Scientists successfully bioengineered human liver organoids that faithfully mimic key features of fatal liver disease in the laboratory. This allowed them to uncover underlying disease biology in the organoids and test a potential therapy that in preclinical lab tests reversed an often-fatal childhood condition called Wolman disease.
28.05.2019The production of artificial organs is a hot research topic. In the near future, artificial organs will compensate for the lack of organ donations and replace animal experiments. Although there are already promising experiments with 3D printers that use a "bio-ink" containing living cells, a functional organ has never been created in this way.
24.05.2019University of Maryland School of Medicine study shows the potential of transplanted stem cell secretions as a liquid biopsy.
23.05.2019An artificial portable kidney that patients who have suffered renal failure could wear is to be created by a research team at the University of Saskatchewan with federal funding.
01.03.2019People suffering from lung disease temporarily need ventilator support because they are unable to breathe naturally. Mechanical ventilation is designed to ensure the survival of these patients. The goal is to adapt the ventilator settings and tailor them the patient's specific needs and prevent lung tissue damage.
22.02.2019According to the WHO, ten percent of babies worldwide are born prematurely. Since most organs of these tiny babies have not fully developed yet, it can quickly lead to complications and disorders and most notably affect the lungs of the premature infants. What's more, infections require gentle treatment, as the preemies themselves are fragile and susceptible – making this a challenging situation.
01.02.2019In vitro processes and animal tests are used to develop new medications and novel therapeutic approaches. However, animal testing raises important ethical concerns. Organ-on-a-chip models promise to be a feasible alternative. In a system the size of a smartphone, organs are connected using artificial circulation.
01.02.2019The liver, nervous tissue or the intestines: all are important human organs that have in the past been tested for their function and compatibility using animal or in vitro test methods. In recent years, TissUse GmbH, a spin-off of the Technical University of Berlin (TU Berlin), has launched multi-organ chip platforms. But that’s not all.
22.01.2019Whether in the office, at school or behind the wheel: we spend a lot of time sitting and often stay in the same position for too long. The possible side effects are stiffness, back problems and pain. The SensA-Chair smart seating solution combats decreased mobility and ensures dynamic sitting.
05.10.2018Many people have damaged or suboptimally functioning lungs. An accurate diagnosis and subsequent treatment are vital to protect this life-sustaining organ. Modern imaging solutions help physicians and patients understand what happens inside the lungs.
23.07.2018Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.
08.05.2018Multidrug-resistant organisms that are treated with a dosage that exceeds the regular dose a hundred times and at temperatures of over 40 degrees Celsius – the human organism is unable to handle it. Yet if the diseased organ is treated outside of the body, extreme conditions are an option. For the first time, physicians have succeeded in treating a severe case of pneumonia by using the OCS.
08.02.2018When body tissue is reconnected during a tumor operation in the gastrointestinal tract, surgeons need information about the current state of these so-called anastomoses. The new, non-invasive hyperspectral imaging technology now makes it possible to measure the crucial parameters during surgery and thereby increase surgical precision.
08.11.2017Major surgeries in the abdominal region often result in kidney injury in patients. Meanwhile, the clinical manifestations don't present until one or two days after the procedure. This causes physicians to lose valuable time to treat patients. The University Hospital Regensburg has researched a new concept for the treatment of kidney injuries for several years.
08.11.2017Every year in September, MEDICA Preview takes place at the University Hospital Hamburg-Eppendorf. It is intended to give visitors, exhibitors and the trade press a foretaste of MEDICA in November and tomorrow's medicine.
