When a breast tumor is detected, many women opt to have a lumpectomy, which is surgery designed to remove the diseased tissue while preserving the breast. But during this procedure, doctors cannot learn right away whether all of the cancerous tissue has been removed, with no microscopic signs that cancer cells were left behind.
On this episode of The Pulse, a major step toward an artificial pancreas, detecting disease from just one drop blood, creating mature human cardiac patches from human heart cells, and a smart sock that helps runners improve their technique and prevent injuries.
In November 2012 and February 2013, Andrew Johnson underwent a surgical procedure, Deep Brain Stimulation surgery, to help control his motor symptoms. This video represents his experience of how DBS has helped him. He is using a device from Medtronic.
Researchers used a flat interface nerve electrode to demonstrate direct sensory feedback. By interfacing with residual nerves in the patient's partial limb, some sense of touch by the fingers is restored. Unlike visual feedback, direct sensory feedback allows patients to move a hand without keeping their eyes on it—enabling simple tasks, like rummaging through a bag for small items, not possible with today's prosthetics.
Researchers are developing a new type of gripping arm for medical and engineering applications, using the the flexible armor of seahorses as a model. A team at the University of California San Diego says the creature's natural armor plating provides a degree of strength and flexibility that does not exist outside nature. Tara Cleary reports.
On this episode of The Pulse, rewired nerves from amputated limbs allow for prosthetic control with existing muscles, a bioengineered blood vessel is transplanted, diabetes is diagnosed through breath analysis alone, and a new technology is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body.
Professor Il-Doo Kim of Materials Science & Engineering, KAIST, developed an exhaled breath sensor that is composed of highly porous tin dioxide (SnO2) nanofibers with a unique nanostructure functionalized by catalytic platinum (Pt) particles. This unique structure reacts to acetone gas, which is known as a biomarker of diabetes, for the fast diagnosis of the disease within 10 seconds.
Researchers at Case Western Reserve University used a flat interface nerve electrode (FINE) to demonstrate direct sensory feedback. By interfacing with residual nerves in the patient's partial limb, some sense of touch by the fingers is restored. Other existing prosthetic limb control systems rely solely on visual feedback.
A team of researchers at the Rehabilitation Institute of Chicago (RIC) demonstrated a type of peripheral interface called targeted muscle re-innervation (TMR). By rewiring nerves from amputated limbs, new interfaces allow for prosthetic control with existing muscles. Former Army Staff Sgt. Glen Lehman, injured in Iraq, recently demonstrated improved TMR technology.
Diastolic heart failure is responsible for more than half of all cardiac failure. The condition is usually treated with drugs, but now, a new device being tested in the Czech Republic could provide more effective treatment for millions of sufferers.
In this video, a representative at Nephosity demonstrates MobileCT, an app for mobile collaborative teleradiology. It allows for a user (such as a doctor or patient) to use their mobile devices to view x-rays, MRIs, etc., and to collaborate with other users (such as other doctors or relatives).
Professor Brian T. Cunningham and his graduate students demonstrate their development of using a smartphone camera as a high resolution spectrophotometer. Cunningham’s group is now collaborating with other groups across campus at the U. of I. to explore applications for the iPhone biosensor.
Graduate students developed a new textile microfluidic platform using hydrophilic threads stitched into a highly water-repellent fabric. The new fabric works like human skin, forming excess sweat into droplets that drain away by themselves, said inventor Tingrui Pan, professor of biomedical engineering.
Paula Spurlock was experiencing intense itching following hip replacement surgery. It turned out that she was allergic to the hip implant and the bone cement used to keep the implant in place. Now, a new test can help to prevent this type of problem for future patients who require an orthopedic implant.
The tail of a seahorse can be compressed to about half its size before permanent damage occurs, engineers at the University of California, San Diego, have found. The tail’s exceptional flexibility is due to its structure, made up of bony, armored plates, which slide past each other.
