Researchers at Hesperos, Inc., a biotech firm based in Florida, have collaborated with Roche and the University of Central Florida to develop a multi-organ lab-on-a-chip system for drug testing. The device includes human organ-derived tissue constructs that allow for the efficacy and side-effects of anti-cancer drugs in various organs to be tested in a way that does not involve laboratory animals. The technique is another step for lab-on-a-chip devices in making preclinical testing easier, less expensive, and more humane. Lab-on-a-chip devices for drug testing are an active area of research,...
Researchers at the University of Washington have used machine learning to teach an AI system to identify when someone is having a cardiac arrest. The system learned to identify agonal breathing, which occurs when someone gasps for breath during cardiac arrest, with a high degree of accuracy. The technology can be embedded into a variety of listening devices, such as smart speakers or smartphones, to alert authorities and loved ones to someone having a heart attack while they sleep. Approximately half a million Americans die from cardiac arrest annually. Cardiac...
Materialise, a 3D printing company with a focus on patient-specific parts, has received FDA clearance for its Mimics Enlight cardiovascular planning software suite. The product's initial application will be in planning complex transcatheter mitral valve replacement (TMVR) procedures. Developed with the help of the Henry Ford Health System in Detroit, and in particular Dr. Dee Dee Wang, MD, FACC, Director of Structural Heart Imaging at the hospital, the Mimics Enlight software lets cardiologists identify which patients are appropriate for treatment and measures various important parameters to make sure that a...
Innovega Inc., a systems engineering and lens development company with offices in Washington and California, has created eMacula, a new generation of eyewear that combines smart contact lenses and stylish, lightweight glasses. The system will be tailored to the needs of vision impaired patients who will benefit from both lens-based vision correction and from magnification and digital enhancement of the view of their surroundings. The eMacula solution responds directly to the fact that the vision of these patients cannot be sufficiently improved by techniques based on the use of normal...
Cancerous tumors can be very inconsistent in how they respond to different therapies. While the tumor of one patient can rapidly shrink when exposed to a given medication, another patient suffering from the same kind of tumor may not get any benefit from that same drug. This phenomenon highlights why personalized medicine is such an important component of biomedical research. To help identify which therapies will work for a given tumor, researchers at University of Geneva (UNIGE) in Switzerland have developed a way of recreating tumors in 3D outside the...
Researchers from Emory University and Harvard University have developed a machine learning algorithm that can predict an individual’s likelihood for developing psychosis based on their speech patterns. Psychosis may be described as a “break with reality,” including hallucinations and delusions, which may arise from schizophrenia or other mental disorders. The researchers' work, recently published in Nature Communications, demonstrates their tool can predict whether an at-risk person will develop psychosis with 90% accuracy. This is an exciting development for those who are at risk of psychosis, and can provide valuable medical...
Our memories often seem ephemeral, coming and going without any obvious reasons. Researchers at UCLA seem to have come up with a way to bring some memories back that would probably otherwise have gone missing forever. The team relied on transcranial direct current stimulation (tDCS), a technology that can direct low energy electricity into specific parts of the brain. Based on previous research, the team targeted the left rostrolateral prefrontal cortex, which is associated with abstract thought and processing signals coming from other parts of the brain. What they discovered...
Tissue biopsies of skin lesions can be unpleasant and quite painful. Moreover, a biopsy typically doesn't sample the whole lesion and doesn't provide much information about a given lesion's size and depth. Now, scientists at Rutgers University have developed and tested a new device that relies on two different mechanisms to analyze skin lesions. The new "virtual biopsy" device relies on vibrational optical coherence tomography to analyze tissue. It delivers pulses of near-infrared light, along with sound clicks, into the target tissue. The combination technology can identify how deep a...

Assessing the health of tissues deep inside the body is a major need and challenge in medicine. Imaging modalities such as MRI, CT, and ultrasound provide very little information about the composition and environment of tissues being examined. Now, researchers at the University of Edinburgh, Heriot-Watt University, and Bath University, all in the UK, have developed an ultra-thin probe, similar to a fine piece of hair, that can measure the pH and oxygen concentration deep within the lungs. The same technology, slightly modified, has potential in other parts of the...

A couple of years ago a team of U.S. and U.K. scientists came up with a way of making molecular motors that can drill through cancer cells, destroying them in the process. The researchers, from Rice University, Durham University, and North Carolina State University, used an ultraviolet (UV) light source to energize these motors, but such light is dangerous and can cause a host of unintended consequences. Now, the same team has managed to use a phenomenon called two-photon absorption, powered by a near-infrared laser, to activate the motors, avoiding...

Life science organizations successfully increase sales when all departments collaborate to enhance results. Sharing information between departments can focus on fulfilling the needs of customers and strengthening commercial performance. At the 9th Digital Marketing for Medical Devices, taking place on August 5–7 in Minneapolis, attendees will learn to work together and share information for the latest devices and compare efforts to grasp the interest of physicians and other key stakeholders. Kick off the first day with our Marketing and Sales Collaboration Day and hear from industry professionals on the featured sessions below: Streamline...
