No stain? No sweat: Terahertz waves can image early-stage breast cancer without staining. A team of researchers at Osaka University, in collaboration with the University of Bordeaux and the Bergonié Institute in France, has succeeded in terahertz imaging of early-stage breast cancer less than 0.5 mm without staining, which is difficult to identify even by pathological diagnosis. Their work provides a breakthrough towards rapid and precise on-site diagnosis of various types of cancer and accelerates the development of innovative terahertz…
The results of the VIBRA project of the Politecnico di Milano Funded by ERC and just completed, the project uncovers the cellular mechanisms underlying various diseases thanks to a new optical microscopy technique. The VIBRA project, “Very fast Imaging by Broadband coherent Raman”, has just ended at the Politecnico di Milano. Funded by the prestigious European Research Council of the European Community and lasted 5 years (2015-2020), it led to the development of a new revolutionary optical microscope in the…
A joint research team led by Prof. WANG Hui and Prof. LIN Wenchu from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science developed a synthesis of metal-free multifunctional therapeutic reagents, called graphitic carbon nitride quantum dots embedded in carbon nanosheets (CNQD-CN), via a one-step hydrothermal treatment. Metal-free multifunctional nanomaterials have broad application prospects in integrated cancer diagnosis and treatment. The team took an organic solvent (formamide) as the carbon and nitrogen source and then developed CNQD-CN….
Researchers at the University of Colorado Boulder and the University of Colorado Anschutz Medical Campus have developed a new way to diagnose diseases of the blood like sickle cell disease with sensitivity and precision and in only one minute. Their technology is smaller than a quarter and requires only a small droplet of blood to assess protein interactions, dysfunction or mutations. The team published its results Oct. 15 in the journal Small. “In Africa, sickle cell disease is the cause…
Imaging findings of in situ pulmonary artery thrombosis associated with radiation therapy are different from acute pulmonary emboli and do not appear to embolize. According to an article in ARRS’ American Journal of Roentgenology (AJR), the imaging findings of in situ pulmonary artery thrombosis (PAT) associated with radiation therapy (RT) are different from those of acute pulmonary emboli and do not appear to embolize. Due to the differences in clinical prognosis and subsequent management strategies, in situ PAT associated with…
Strengthening innovative power of German medical technology industry Fraunhofer Institute for Biomedical Engineering IBMT as partner in the BMB joint project “EUREKA-AMeLie: Advanced Systems Engineering aims to reduce production costs for SMEs and increase design flexibility – Exemplary testing on application cases from the fields of in-vitro diagnostics, medical devices and implants The medical technology industry is facing major challenges due to digitalization, new manufacturing technologies and changes in the regulatory framework. In order to strengthen the innovative power of…
Should I or shouldn’t I? The activity of individual nerve cells in the brain tells us how confident we are in our decisions. This is shown by a recent study by researchers at the University of Bonn. The result is unexpected – the researchers were actually on the trail of a completely different evaluation mechanism. The results are published in the journal Current Biology. You are sitting in a café and want to enjoy a piece of cake with your…
Dual-energy CT adds value to routine interpretation of emergency department imaging studies by increasing radiologists’ diagnostic confidence, leading to a reduction in downstream imaging and associated costs. According to an open-access article in ARRS’ American Journal of Roentgenology (AJR), dual-energy CT (DECT) added value to routine interpretation of emergency department (ED) imaging studies by increasing radiologists’ diagnostic confidence, leading to a reduction in downstream imaging and associated costs. William D. Wong of Vancouver General Hospital and colleagues queried his institution’s…
One feature of the COVID-19 virus that makes it so difficult to contain is that it can be easily spread to others by a person who has yet to show any signs of infection. The carrier of the virus might feel perfectly well and go about their daily business–taking the virus with them to work, to the home of a family member, or to public gatherings. A crucial part of the global effort to stem the spread of the pandemic,…
An international team led by current and former McMaster University researchers has developed an artificial lung to support pre-term and other newborn babies in respiratory distress. The group has proven the concept using a live piglet, a major step along the route toward approval for use in humans, where the portable device could save many lives and prevent catastrophic damage by taking up some of the placenta’s role in oxygenating the blood until babies are able to breathe independently. “This…
Cold Spring Harbor Laboratory (CSHL) scientists have taught computers to recognize a neuron in microscope images of the brain more efficiently than any previous approach. The researchers improved the efficiency of automated methods for tracing neurons and their connections, a task that is increasingly in demand as researchers work to map the brain’s densely interconnected circuits. They did it by teaching the computer to recognize different parts of neurons, each of which have different characteristics. Such connection maps are critical…
New method could jump-start creation of tiny medical devices for the body. Researchers at the National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as drug delivery systems or flexible electrodes that can…
Rubbery electronics offer promise for new applications A medical robotic hand could allow doctors to more accurately diagnose and treat people from halfway around the world, but currently available technologies aren’t good enough to match the in-person experience. Researchers report in Science Advances that they have designed and produced a smart electronic skin and a medical robotic hand capable of assessing vital diagnostic data by using a newly invented rubbery semiconductor with high carrier mobility. Cunjiang Yu, Bill D. Cook…
Landshut University of Applied Sciences project develops device that transmits the medical devices’ acoustic alarm signals directly to the rescue services’ headsets When injured people have to be rescued by rescue helicopter after an accident, every second is precious. One problem for rescue teams during such missions though is that they cannot immediately hear the medical devices’ alarm signals due to the high noise level in the helicopter and are therefore often only able to react with a time delay….
“Honey, I shrunk the detector”: Researchers have developed the world’s smallest ultrasound detector Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as super-resolution imaging. Researchers at Helmholtz…
Approach to electromagnetic stimulation of nervous tissue Today, a large number of diseases are treated with medication. This is often associated with side effects that can be serious for people who are already ill. A new therapeutic approach, known under the keyword “bioelectronic medicine”, provides for the therapy of diseases by means of electrostimulation. Since April 2019, the Fraunhofer Institute for Biomedical Engineering IBMT has been contributing its many years of expertise in the field of intelligent miniaturized active implants…
