Cancer diagnosis is confirmed through histopathology by removing a part of the tissue in question after conducting imaging tests such as MRI, CT, ultrasound, or endoscopy. Based on this clinical diagnosis, the cancerous tissue is surgically removed and suspected tissues or lymph nodes are additionally examined. Future treatment plans, chemotherapy, and radiation are formulated based on these results. Recently, a research team led by POSTECH and Gachon University College of Medicine has developed a machine learning-based histopathology method. A research…
Lung model mimicking complex anatomy may enable air volume assessment. Take a nice, deep breath. Now imagine your lungs: myriad airways like branches, each with tiny alveoli like leaves. This alveolar structure is key to the absorption of oxygen and excretion of carbon dioxide that we call “breath.” As we breathe, the volume of gases in the lungs is continually changing with varying degrees of inhalation and exhalation. These volumes are medically important for clinical assessment and diagnosis of respiratory…
A needle-free COVID-19 vaccination could be possible, with University of Queensland scientists successfully protecting mice from the virus by administering a US-developed vaccine candidate with a ‘patch’. The University of Texas Hexapro vaccine candidate – delivered via the UQ-developed and Vaxxas-commercialised high-density microarray patch (HD-MAP) – provided protection against COVID-19 disease with a single, pain-free ‘click’ from a pocket-sized applicator. Dr David Muller, from UQ’s School of Chemistry and Molecular Biosciences, said the vaccine patch produced strong immune responses that were shown to be effective when…
Bone screws and plates that dissolve on their own after a broken bone has healed promise to be of great benefit – they could save some patients from having to undergo follow-up surgery. A research team led by the Helmholtz-Zentrum Hereon has now used a 3D X-ray method to determine for the first time quantitatively how different of magnesium alloys dissolve over time under body-like conditions. The result provides indications of which materials are particularly suitable for certain types of…
Telemedical monitoring more reliable than self-assessment. Using telemedicine, COVID-19 patients can be cared for safely at home – from initial home isolation to recovery or, in case problems arise, admission to hospital. A team from the Technical University of Munich (TUM) has now successfully demonstrated this in a study involving 150 patients with risk factors for a severe progression of the disease. COVID-19 patients are required to go into home isolation. But this can be dangerous for high-risk patients if…
Researchers from the University of Notre Dame and the University of Florida have developed a sensor that could diagnose a heart attack in less than 30 minutes, according to a study published in Lab on a Chip. Currently, it takes health care professionals hours to diagnose a heart attack. Initial results from an echocardiogram can quickly show indications of heart disease, but to confirm a patient is having a heart attack, a blood sample and analysis is required. Those results can…
This technology will give researchers insight into how the nervous system works and the chance to develop new ways of treating neurological disorders. Grégoire Courtine doesn’t hesitate to use the word “revolutionary” when describing the emerging field of optogenetics – a technology that uses pulses of light to control individual neural activity – and what it could mean for neuroscience. Courtine, director of the NeuroRestore research center (with neurosurgeon Jocelyne Bloch), is currently developing an optogenetic implant together with Stéphanie…
Stanford University and the University of North Carolina Chapel Hill develop microneedle vaccine patch that outperforms needle jab to boost immunity. Scientists at Stanford University and the University of North Carolina at Chapel Hill have created a 3D-printed vaccine patch that provides greater protection than a typical vaccine shot. The trick is applying the vaccine patch directly to the skin, which is full of immune cells that vaccines target. The resulting immune response from the vaccine patch was 10 times…
Researchers at the Beckman Institute Biophotonics Imaging Laboratory applied deep learning to polarization-sensitive optical coherence tomography to better detect cancer. Yi “Edwin” Sun, a Ph.D. candidate in electrical and computer engineering at the University of Illinois Urbana-Champaign and member of the Beckman Institute’s Biophotonics Imaging Laboratory headed by Stephen Boppart, explored how deep learning methods can make polarization-sensitive optical coherence tomography, or PS-OCT, more cost-effective and better equipped to diagnose cancer in biological tissues. The paper, titled “Synthetic polarization-sensitive optical…
Scientists at Cornell University have created cell-size robots that can be powered and steered by ultrasound waves. Despite their tiny size, these micro-robotic swimmers – whose movements were inspired by bacteria and sperm – could one day be a formidable new tool for targeted drug delivery. For more than a decade, Mingming Wu’s lab has been investigating the ways microorganisms, from bacteria to cancer cells, migrate and communicate with their environment. The goal was to create a remotely controlled micro-robot that…
Woman receives novel type of artificial heart at UofL Health — Jewish Hospital by University of Louisville physicians. A cardiothoracic surgical team with UofL Health – Jewish Hospital and the University of Louisville has performed the world’s first Aeson® bioprosthetic total artificial heart implantation in a female patient. The investigational device, currently intended as a bridge to heart transplant, is part of an Early Feasibility Study (EFS) sponsored by CARMAT, a French medical device company, in partnership with UofL, UofL…
A simple but revolutionary approach to early Alzheimer’s diagnosis is being pioneered by researchers through an initiative that could pave the way for improved outcomes for individuals who develop the disease in the future. The innovative research, led by psychologists at the University of Bath and funded by the dementia charity BRACE, uses a new method to passively measure brain activity. It involves participants looking at a series of flashing images on a computer over two minutes, whilst their brain…
Researchers at the University of Bonn show how machine learning improves the evaluation of blood analysis data. The presence of cancer of the lymphatic system is often determined by analyzing samples from the blood or bone marrow. A team led by Prof. Dr. Peter Krawitz from the University of Bonn had already shown in 2020 that artificial intelligence can help with the diagnosis of such lymphomas and leukemias. The technology fully utilizes the potential of all measurement values and increases…
Capturing the intricacies of the brain’s activity demands resolution, scale, and speed—the ability to visualize millions of neurons with crystal clear resolution as they actively call out from distant corners of the cortex, within a fraction of a second of one another. Now, researchers have developed a microscopy technique that will allow scientists to accomplish this feat, capturing detailed images of activity of a vast number of cells across different depths in the brain at high speed and with unprecedented…
3D-printed origami technology at the heart of low-cost, portable ventilators aimed at improving pandemic treatment and revolutionizing healthcare delivery. Researchers in Simon Fraser University’s Additive Manufacturing Lab are replicating a distinctive artform—the subtle folding of origami—to create 3D printable technologies to aid in the fight against COVID-19, and help doctors to identify and diagnose various health conditions. Highlighting the work, led by SFU School of Mechatronic Systems Engineering’s associate professor Woo Soo Kim, is a low-cost, portable 3D-printed ventilator, driven…
An electronic “nose” is capable of detecting with 86% accuracy when a lung transplant is beginning to fail, according to research presented at the ‘virtual’ European Respiratory Society International Congress today. Ms Nynke Wijbenga, a PhD student and technical physician at Erasmus University Medical Center, Rotterdam, The Netherlands, told the congress that the finding could enable doctors to spot at an early stage when a lung transplant is failing, known as chronic allograft dysfunction (CLAD), so that they could provide…
