Artificial Intelligence Automatically Spots Polyps During Colonoscopies (Interview)
Artificial intelligence is making big strides in a variety of medical fields, including radiology, oncology, and even ophthalmology. Now a company called Wision AI, based in Shanghai, Cina, is adapting artificial intelligence vision software to help doctors spot polyps during a colonoscopy. The technology is meant for real-time use and the procedure itself doesn’t change much from existing colonoscopies.
We spoke with JingJia Liu, Cofounder and CEO of Wision AI about the company technology, how it works, and what it is capable of already.
Medgadget: Can you briefly describe your company’s technology and ...

Medgadget Sci-Fi Contest 2018: Meet The Authors and Read Their Stories
From Jules Verne to Isaac Asimov, science fiction writers have inspired scientists, explorers, and thrill seekers to influence the future of humanity. While Sci-Fi may seem like it’s about the distant future, more often than not it’s commentary on rudimentary technologies that already exist and that are about to mature and reveal their true potential.
The authors of this year’s Medgadget Sci-Fi Writing Contest are certainly in tune with the latest trends in biomedicine, the introduction of artificial intelligence (AI) into clinical practice, and genetic manipulation taking place in thousands of labs aroun...

DNA Origami Nanoparticles to Treat Acute Kidney Injury
DNA origami is a technique for building different shaped molecules out of the four standard nucleotide bases. Various forms can be constructed, such as tubes, pyramids, and cubes, and the shapes of these molecules can significantly affect their functionality. Now they’ve been shown to be useful for treating acute kidney injury (AKI).
The DNA origami nanostructures (DONs), that researchers at University of Wisconsin-Madison, Arizona State and a few institutions in China have developed, have been shown to protect kidneys from succumbing to AKI and to heal already injured kidneys. The effect was comparable to the curre...

Machine-Learning Can Help Anesthesiologists Foresee Complications
During surgeries, anesthesiologists must monitor the vital signs of patients and administer the proper doses of anesthesia at the right times. While managing these responsibilities in a high-pressure situation, it can be difficult to anticipate surgical complications. One issue that can arise is hypoxemia, a condition in which the blood oxygen levels of the patient become too low. Hypoxemia has been associated with serious consequences such as cardiac arrest, cerebral ischemia, and post-operative infections. Although anesthesiologists can monitor blood oxygen saturation in real-time, there are currently no reliable ways of...

Researchers are Using Non-Invasive Antenna for MRI
Researchers from the Massachusetts Institute of Technology are taking magnetic resonance imaging (MRI) to new levels. By using a tiny radio antenna implanted in the brain as a sensor, they can detect electrical currents and light generated by luminescent proteins, according to a study published this week inNature Biomedical Engineering.“MRI offers a way to sense things from the outside of the body in a minimally invasive fashion. It does not require a wired connection into the brain,” saidthe study ’s lead author Aviad Hai, PhD, a postdoc working in Alan Jasanoff, PhD’s, brain imaging lab. “We can implant the se...

MRI Implant to Detect Light and Electric Fields Inside Brain
Monitoring certain kinds of processes happening inside the brain can be pretty easy or exceedingly difficult. EEG, for example, provides a pretty good look into the brain using relatively simple technology, while measuring light emitted by luminescent proteins within the brain is incredibly challenging.
Now researchers at MIT are adapting MRI technology, coupled with a tiny implant, to be able to measure both electric fields and light at excellent spatial resolution. Previously, the same would require extremely invasive procedures, with wires protruding from the head, that essentially make it impossible to do so in most c...

Using MRI to Create 3D Heart Models to Improve Cardiac Procedures
Researchers at John Hopkins University ’s schools of Engineering and Medicine are using MRI images of human hearts to create 3D personalized models for physicians to identify and eradicate heart tissue that can cause the organ to go into cardiac arrhythmia. Their findings were recently publishedinNature Biomedical Engineering.Typically, cardiac ablation, or the process of locating and destroying tissue associated with errant electrical impulses, involves loose estimations and uncertainty. The conventional procedure requires the physician to thread a catheter to the heart and destroy specific heart tissues using radiofre...

Flexible Stick-On Ultrasound Patch Measures Central Blood Pressure
Scientists at the University of California San Diego created a flexible ultrasonic patch that can measure the blood pressure in major vessels such as the jugular vein and carotid artery. The technology has already shown, in a proof-of-concept study, that it may be made as accurate as invasive means to measure the central blood pressure. If turned into a product, patients may soon benefit from continuous, highly accurate blood pressure monitoring the reach, convenience, and benefits of which existing BP cuffs or invasive lines simply can’t provide. Moreover, it may serve as an intraoperative technique for real-time bl...

Epigenetic Changes Guide Development of Different Brain Regions (Dana Foundation):
“It’s one of the greatest standing mysteries in neuroscience: Given that each cell in the human body contains the same DNA, how, exactly, does the brain develop into distinct functional regions, supported by different cell types? And how might that developmental program go awry, resulting in neurodevelopmental disorders like schizophrenia or autism? The answers may...

Artificial Model of Heart Ventricle for Studying Cardiac Diseases, Drugs, Therapies
Custom-built artificial hearts are still something from science fiction, but the engineering knowledge to get there is already being assembled in labs around the world. One important piece of the puzzle has just been reported on by researchers at Harvard University, who have built a model of the heart’s left ventricle, seeded with living heart cells, that beats on its own just like the real thing.
The device is made of a specifically engineered nanofiber scaffold throughout which living heart cells have been implanted. The scaffold, and the technique to make it, have also been designed by the Harvard researchers. A s...

Microparticles Carrying Bacteria-Killing Viruses Halt Deadly Pneumonia
Antibiotics suffer from eventual resistance by the bacteria and the fact that they can be quite indiscriminate in who they attack, including the gut’s healthy microbiome.
But, there are also bacteriophages, which are viruses that can kill specific bacteria without harming any other bacteria. The problems with bacteriophages, though, is that they’re hard to produce in large quantities and difficult to deliver, particularly into the lungs.
Researchers at Georgia Tech are now reporting that they developed special microparticles packed with bacteriophages that can be inhaled to fight bacterial lung infections.
The...

New Device Captures Circulating Tumor Cells Directly Within Blood Vessels
Circulating tumor cells (CTCs) are present in the blood of people suffering from most cancers, but because of their rarity their presence is very difficult to spot. A number of technologies have been developed in the past to capture and count CTCs (see flashbacks below), but they tend to still have a number of limitations. The main problem is that because CTCs are so rare, a very large amount of blood is required to have a chance of finding enough of the cells to point toward a diagnosis. Scientists at Stanford University have now developed their own unique approach for capturing CTCs that relies on magnets that work dir...

Nano-Patterned Bone Implants Vascularize and Generate Bone Better Than Smooth Ones
A University of Toronto team from the Institute of Biomaterials and Biomedical Engineering (IBBME) discovered that nano-scale surface topology matters when it comes to vascularization of bone implants. They compared two titanium implants of the same chemical composition and varied only their surfaces at the nano scale. One was smooth and the other was rough and nano-patterned.
In their experiments of bone regrowth around a skull implant, they observed over three times more bone formation around the implant with a rough surface. To uncover the mechanism, they turned to intravital microscopy to visualize the implant at micr...
