Most brain related diseases are identified through the symptoms that patients experience. Real, direct testing may be on the horizon thanks to researchers at Washington University in St. Louis who have been looking at whether functional connectivity MRI (fcMRI), a new technique that maps outs the interconnectedness of the brain, may help spot unusual patterns and therefore disease. The team focused on spotting "fundamental differences" in the wiring of the brains of individual human volunteers. “This is a step toward realizing the clinical promise of functional connectivity MRI,” in a statement said...
Researchers at the University of Texas at Austin have developed new technology to investigate the relationship between vision and foot placement during walking. The devices include an eye tracker and a motion-tracking suit that record gaze and full-body kinematics as a wearer navigates various terrains. The insights provided by the technology could help researchers to understand what is going on in the brain during walking. This technology could assist them in developing new prosthetics, robots, and new treatments for diseases that affect mobility, such as Parkinson’s. Walking requires precise coordination...
Pacemakers have gotten so small that they can now reside inside the heart itself. This avoids reliance on electric leads that snake from the implant to the interior of the heart, which come with a number of potential problems. On the other hand, advanced multi-site sensing leads are able to provide considerably more nuanced monitoring of the heart than a pacemaker attached to one spot in the heart. Students at Rice University are working on overcoming this limitation by developing a very different approach. They are working on tiny, grain...
Getting pregnant is not always as easy as our sex education teachers promised it would be. It can be stressful, frustrating, and heart wrenching. One of the key factors to a successful conception is timing intercourse during the woman’s fertile window – a period of time that includes the five days prior to ovulation and up to 24 hours after ovulation. In order for a woman to determine her fertile window, she needs to be able to pinpoint when she ovulates. Although many signs and symptoms can indicate ovulation, such...
Graphene, the material that consists of a one atom thick layer of carbons, is so impressive that its development was awarded a Nobel Prize in physics. To add to its abilities, researchers at Chalmers University of Technology in Sweden used it to create microscopic spikes that kill bacteria upon contact. Because our native cells are generally much bigger than bacterial cells, the same spikes, working as a bed of nails, don't seem to damage human tissue. The technology surely has incredible potential for preventing the growth of bacterial infections on...
Angel Medical Systems, based in Tinton Falls, New Jersey, won FDA approval for its AngelMed Guardian implantable device that may help detect oncoming heart attacks before they even happen. It looks like a pacemaker and it monitors for ST segment changes, an ECG sign of ischemia. When it detects sustained ST segment changes, the implant sends a signal to an external device that then warns the patient to seek medical care. The hope is that early detection will lead to many heart attacks avoided, or at least whose effects would...
University of Connecticut researchers have created a new orthopedic material for fixing bones that's made out of spider silk, itself one of the world's strongest natural materials. While silk fibroin, the protein in silk that gives it strength, is already in use in sutures and other medical devices, this is the first time it was made into an extremely tough polymer composite. The new material, a combination of silk and  polylactic acid, a biocompatible plastic,  has impressive mechanical characteristics that are siumilar to metal. But, since there's no metal, there aren't...

The promise of exoskeletons is to make manual labor easier by providing extra strength to the arms, and hopefully alleviating injuries and overall impact on the body. Researchers at Ohio State wanted to study whether this is really true, so they evaluated whether a Steadicam device, commonly used passive device for stabilizing cameras during filming, really does help workers in the long run. In short, what they found out is that the unpowered device, really transfers the impact to other parts of the body, increasing the load on the spine...
Opioid abuse having become a serious health threat for many and a dire societal problem in many parts of America. Perhaps a simple messaging app can help? A collaboration from Washington University School of Medicine and Epharmix, a nearby company based in St. Louis, has released a simple text-based service to help people kicking the addiction. It questions the patients about their feelings, keeps tabs on their progress, and provides an easy way to seek help. It helps care providers to direct their effort where needed, while helping to automate and...
Researchers at Georgia Tech have developed a technique to remotely activate genetically-modified T cells to attack cancer. The method employs a near-infrared laser that heats gold nanorods present in the tumor, causing local heating. This heat activates the T cells, making them more aggressive in killing cancer cells. Immunotherapies, such as T cell therapy, hold significant promise in treating cancer. However, the technique is still very new, and isn’t always effective. “Right now, we're adept at harvesting a patient's own T-cells, modifying to target cancer, growing them outside the body...
Last year, Medgadget spoke with BioSig Technologies about the company's PURE EP System for detection of cells that cause arrhythmias. PURE EP is a surface electrocardiogram and intracardiac multichannel recording system that acquires, processes, and displays high fidelity cardiac recordings required during electrophysiology studies and catheter ablation procedures. A nationwide survey of electrophysiologists in 2017 highlighted the noise reduction and overall signal clarity and accuracy as differentiating factors setting PURE EP apart from other electrophysiology signal recording and processing systems. Mayo Clinic's Dr. Samuel J. Asirvatham, a BioSig Scientific Advisory Board member has stated...
