Stem cells hold a great deal of promise in treating a huge variety of human diseases. Although much hyped to the general public some years ago, it turned out to be very difficult to safely use stem cells to generate replacement tissues without inadvertently introducing tumors or other maladies. Knowing how stem cells differentiate, and whether they turn into healthy cells, is key to overcoming a major hurdle for stem cell therapies. Now, a team at Rutgers University has developed a platform and accompanying imaging technology that can accurately monitor...Read More
Researchers at Lawrence Berkeley National Laboratory have developed synthetic peptide-coated magnetic beads that can be used to detect the presence of misfolded proteins in blood samples. Misfolded proteins are a factor in a number of diseases, including prion diseases, Alzheimer’s, and Parkinson’s. To date it has been difficult to detect such proteins in patient blood samples, often because they are present in very small quantities and closely resemble their correctly folded cousins. The new beads bind to specific misfolded proteins in blood samples, paving the way for rapid and convenient...Read More

While there are a number of drugs to treat Attention Deficit Hyperactivity Disorder (ADHD), they can have some pretty serious side effects. Researchers in Singapore at the country's Institute of Mental Health (IMH), Duke-NUS (National University of Singapore) Medical School, and A*STAR (Agency for Science, Technology and Research), have developed a system that combines neuromonitoring with video games to help kids improve their ADHD symptoms. Neeuro Pte Ltd. is a local company that has been spun off to commercialize the technology. So far, a randomized controlled trial of the prototype...Read More
As kids grow, their brains undergo a development process that is poorly understood. Children can have short attention spans, move around a lot, and are not easy to get into and then keep still inside a stationary scanner. Now, a collaboration of scientists from University of Nottingham, University of Oxford, and University College London has developed a functional magnetoencephalography scanner that young kids can wear while playing video games and doing other normal activities. Using the technology, it may be possible to better understand how a variety of brain conditions...Read More

Ischemic strokes can cause havoc in the brain, but early and properly directed treatment can mitigate a lot of damage. While there are a number of options to unclog blocked arteries, the potential to provide additional drug therapy remains mostly unexplored because of the difficulty in getting medications past the blood-brain barrier. Now, researchers at the University of Manchester are reporting that they were able to pass liposomes across the tiny tears in the vasculature that occur during ischemic strokes. Liposomes are lipid vesicles, naturally produced by the body and...Read More
Philips is releasing a new vital signs monitor designed to offer advanced warning on worsening patient status within general care clinical environments. The EarlyVue VS30 is a newly FDA cleared device featuring Philips' Early Warning Scoring technology that spots tell-tale signs of degradation in patient health, and notifies clinicians sometimes even hours before the onset of symptomatic deterioration. The technology allows for earlier intervention and the prevention of serious events. Notifications and the information display can be set to match each patient's unique needs and the clinic can also adopt...Read More

Monitoring neurons and other excitable cells in vivo for research and clinical applications has usually required the use of electrode arrays. These are quite limited in their electrode density and the area that they can cover. Moreover, the amount of signal generated by the neurological system overwhelms any attempts at building large scale electronic microelectrode arrays. Fluorescent probes are another modality, but they come with a host of limitations and incompatibilities for use on living humans. This false-color scanning electron micrograph shows cardiomyocytes (colored in purple) cultured on an electro-plasmonic...Read More

Omega Medical Imaging, a firm based in Sanford, Florida, has won FDA clearance for its FluoroShield technology, as well as the 2020 Cardiac Flat Panel Detector. FluoroShield automatically aims the radiation beam across the area of interest during interventional procedures utilizing fluoro or cine (short X-ray movies of the beating heart) imaging. This is thanks to Omega's TruBlock auto collimation technology. The tissues around the region are not exposed to radiation, but they're still visible. This is thanks to instantaneous merging of live images in the target area with previously...Read More

Magnetic resonance imaging (MRI) requires very expensive scanners, and special facilities to host them. As things stand, most hospitals around the world can't afford an MRI machine. Things may soon get a bit easier thanks to new metamaterials, developed at Boston University, that improve the quality of MRI imaging. This development may allow lower power MRI scanners, which also cost less, to deliver imaging quality that is comparable with that of more powerful devices. The most obvious way to improve MRI image quality is to use ever more powerful magnets,...Read More
Med-botics, a firm based in Colorado Springs, won FDA Breakthrough Device status for its Oxalert EPO (Enhanced Pulse Oximeter), a device developed to prevent respiratory arrest from opioid overdoses. Post-op patients and others on heavy opioid therapy can stop breathing, which can lead to death if not monitored carefully. The Oxalert EPO monitors patient SpO2 (oxygen saturation) levels and if those fall below 90%, the device attempts to arouse the patient using audible notifications via headphones, gentle electric shocks, or a combination of the two. The device is worn on...Read More

Circulating tumor cells can point to the existence of cancer and provide information about its progression. Capturing these cells remains a tricky process. Dozens of devices have been developed that do their best to grab onto only the cancer cells being looked for, but they all suffer from problems such as poor efficiency, damage to the captured cells, and manufacturing complexity. Researchers at Georgia Tech have now 3D printed a device that works in a novel way to filter out red and white blood cells, leaving only tumor cells that...Read More
