05/02/2019A new technique to study tissue samples in 3D has revealed that pancreatic cancers can start and grow in two distinct ways, solving a decades-old mystery of how tumours form. The new method could help researchers to get more information from tissue biopsies and may lead to improved treatments for pancreatic cancers. The technique was developed by scientists at the Francis Crick Institute.
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.
29/01/2019Researchers have developed a simple blood test that can detect when a newly transplanted lung is being rejected by a patient, even when no outward signs of the rejection are evident.
23/01/2019A previously unknown network of fine capillaries directly connecting the bone marrow with the circulation of the periosteum has been discovered.
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.
11/01/2019With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don't respond to more benign treatments.
11/01/2019A research team led by investigators from the National Institutes of Health and Global Good has developed a computer algorithm that can analyze digital images of a woman's cervix and accurately identify precancerous changes that require medical attention. This artificial intelligence (AI) approach, called automated visual evaluation.
07/01/2019A team of University of Illinois at Urbana-Champaign researchers led by Prof. Stephen Boppart has successfully visualized the tumor microenvironment of human breast tissue after it was surgically removed from a patient in the operating room by using a new portable optical imaging system. This work marks a major step toward providing cancer researchers with a tool for tracking tumor progression.
10/12/2018A team of surgeons from the Perelman School of Medicine at the University of Pennsylvania are the first in the world to use a surgical robot to assist with a bilateral free flap breast reconstruction - a procedure in which tissue is taken from the lower abdomen and used to rebuild the breast. The robot allows surgeons to make a much smaller incision into the abdominal wall muscles.
30/11/2018Researchers from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have found a method for obtaining high-quality images in magnetic resonance imaging (MRI), that requires less contrast medium compared to current methods. An “elastic” protein structure can absorb dissolved xenon in a self-regulating way: The greater the amount of this noble gas, the higher the quality of the image.
27/11/2018Elisa Oltra, head of the Genetic Exppression and Immunity group of the Faculty of Medicine at the Catholic University of Valencia (UCV), in collaboration with Alejandro Caicedo, professor of the Department of Medicine of the University of Miami, have developed a surgical process which makes it possible to place functional fragments of the thymus in the anterior chamber of the eyes of mice.
23/11/2018Biotechnologists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a system to accurately measure muscle weakness caused by structural changes in muscle tissue. The new method allows muscle function to be assessed using imaging without the need for sophisticated biomechanical recordings and could in future even make taking tissue samples for diagnosing myopathy superfluous.
21/11/2018Researchers at the University of New Hampshire have created an easy-to-make, low-cost injectable hydrogel that could help wounds heal faster, especially for patients with compromised health issues.
20/11/2018Using technology similar to the type that powers facial and speech recognition on a smartphone, researchers at the University of North Carolina Lineberger Comprehensive Cancer Center have trained a computer to analyze breast cancer images and then classify the tumors with high accuracy.
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.
24/04/2017Liver cancer is the fifth most common malignant tumor in the world. The tumor can be removed through surgery or by utilizing thermal ablation techniques. If a treatment with conservative methods is no longer possible, there is an alternative: irreversible electroporation (IRE). The effectiveness of this method was now confirmed by a clinical study.
