MHH researchers are working on vascular prostheses made from the blood protein fibrin. The biocompatible alternative to synthetic plastic prostheses is now to be made increasingly fit for clinical use with spider silk. The aorta is the largest blood vessel in the human body. It originates in the heart and carries oxygen-rich blood to all parts of the body. The most common disease of the aorta that requires treatment is an aneurysm. Because the diameter of the aorta is enlarged…
A prototype sensor that measures glucose levels in saliva could eventually offer a simple, rapid and painless way for people to monitor their diabetes, according to the KAUST researchers behind the technology. Diabetes is a disease that occurs when the body cannot regulate its blood glucose levels. Raised glucose levels can lead to cardiovascular disease and other conditions, so it is vital that people with diabetes maintain their blood glucose at moderate levels. People with diabetes have traditionally monitored their…
University of Melbourne researchers have developed a fast, inexpensive and scalable method for engineering blood vessels from natural tissue. Co-led by ARC Future Fellow Associate Professor Daniel Heath and Redmond Barry Distinguished Professor and Shanahan Chair in Frontier Medical Solutions Andrea O’Connor, both from the Department of Biomedical Engineering, the researchers employed a novel approach to ‘tissue engineering’ blood vessels. By combining multiple materials and fabrication technologies, they developed a method to create blood vessels with complex geometries like native…
The new device, which can be incorporated into a bra, could allow more frequent monitoring of patients at high risk for breast cancer. When breast cancer is diagnosed in the earliest stages, the survival rate is nearly 100 percent. However, for tumors detected in later stages, that rate drops to around 25 percent. In hopes of improving the overall survival rate for breast cancer patients, MIT researchers have designed a wearable ultrasound device that could allow people to detect tumors…
Complex-domain neural network achieves state-of-the-art coherent imaging accuracy, reducing exposure time and data volume by more than one order of magnitude. Computational imaging has the potential to revolutionize optical imaging by providing wide field-of-view and high-resolution capabilities. Joint reconstruction of amplitude and phase — known as “coherent imaging or holographic imaging” — expands the throughput of an optical system to billions of optically resolvable spots. This breakthrough enables researchers to gain crucial insights into cellular and molecular structures for biomedical…
Physicists at the University of Würzburg have succeeded in making a new imaging technique ready for use on humans. Radioactive markers and radiation are not necessary for this. Imaging techniques such as computed tomography, magnetic resonance imaging, positron emission tomography and ultrasound have become indispensable in the medical world. Each method not only opens up unique insights into the inside of people, but also allows physicians to draw conclusions about defects or functional processes in the human body. A team…
… could transform detection and treatment of cancers. A tiny robot which can travel deep into the lungs to detect and treat the first signs of cancer has been developed by researchers at the University of Leeds. The ultra-soft tentacle, which measures just 2 millimetres in diameter and is controlled by magnets, can reach some of the smallest bronchial tubes and could transform the treatment of lung cancer. It paves the way for a more accurate, tailored, and far less…
FAU research project about robotic assistance systems receives approximately 2 million euros in funding. A robot performing surgery on humans. What sounds like science fiction could provide support to physicians in the operating room in future. In the “ForNeRo – Seamless and Ergonomic Integration of Robotics into the Clinical Workflow” research network, researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and five other research institutions and five companies are developing methods for integrating robotic assistance systems for surgical applications using intuitive interfaces in…
University of Ottawa team advances clear vision for eye repair. With potential to impact millions, study finds that biomimetic materials pulsed with low-energy blue light can reshape damaged corneas, including thickening the tissue. An injectable biomaterial activated by pulses of low-energy blue light has tremendous potential for on-the-spot repair to the domed outer layer of the eye, a team of University of Ottawa researchers and their collaborators have revealed. Guided by biomimetic design—innovation inspired by nature—the multidisciplinary researchers’ compelling results show that a novel…
Artificial intelligence (AI) can use data from low-dose CT scans of the lungs to improve risk prediction for death from lung cancer, cardiovascular disease and other causes, according to a study published in Radiology, a journal of the Radiological Society of North America (RSNA). The U.S Preventive Services Task Force recommends annual lung screening with low-dose CT (LDCT) of the chest for individuals ages 50 to 80 years with a high risk of lung cancer, such as longtime smokers. Along…
Combining two types of heart scan techniques could help doctors to detect the deadly heart condition hypertrophic cardiomyopathy (HCM) before symptoms and signs on conventional tests appear, according to a new study led by UCL researchers. The research, funded by the British Heart Foundation and published in the journal Circulation, opens the prospect of treating the condition at the earliest stages. Being able to detect HCM earlier than ever before will also assist trials investigating gene therapies and drug treatments…
Specific nerves may be stimulated artificially, for example to treat pain. The finer the nerves, the more difficult it is to attach the required electrodes. Researchers at the Technical University of Munich (TUM) and NTT Research have now developed flexible electrodes produced with 4D printing technology. On contact with moisture, they automatically fold and wrap themselves around thin nerves. The nervous system controls our movements through electrical impulses. These pass from nerve cell to nerve cell until finally, for example,…
… performed by Washington University surgeons. A surgical team from Washington University School of Medicine in St. Louis recently performed the first robotic liver transplant in the U.S. The successful transplant, accomplished in May at Barnes-Jewish Hospital, extends to liver transplants the advantages of minimally invasive robotic surgery: a smaller incision resulting in less pain and faster recoveries, plus the precision needed to perform one of the most challenging abdominal procedures. The patient, a man in his 60s who needed…
Groundbreaking method offers a fast and cost-effective way to observe abnormal metabolic processes live in the magnetic resonance imaging (MRI) scanner / Production of biological contrast agents / Publication in Angewandte Chemie International Edition. A team of scientists from the University Medical Center Freiburg, the German Cancer Consortium (DKTK), and other locations has achieved a significant breakthrough in live observation of metabolic processes in the body using metabolic magnetic resonance imaging (MRI). They have developed a method to modify naturally…

A three-dimensional (3D) bioprinting technology capable of eliminating cancer cells using the function of immune cells has been developed for the first time in the world. Through joint research with the Korea Institute of Machinery and Materials (President Sang Jin Park, hereinafter referred to as KIMM), the Korea Research Institute of Bioscience and Biotechnology (President Jang Seong…
Unveiling a groundbreaking and accurate AI-based method to classify cardiac function and disease using chest X-Rays. AI (artificial intelligence) may sound like a cold robotic system, but Osaka Metropolitan University scientists have shown that it can deliver heartwarming—or, more to the point, “heart-warning”—support. They unveiled an innovative use of AI that classifies cardiac functions and pinpoints valvular heart disease with unprecedented accuracy, demonstrating continued progress in merging the fields of medicine and technology to advance patient care. The results will…
