Protein that protects probiotics from desiccation, leading to improved gut colonization

Summary Probiotic supplements undergo significant water loss before consumption, killing many of their bacteria and rendering them less effective. Vanderbilt researchers have discovered a protein that protects against damage caused by desiccation and shown that this molecular shield can be added to probiotics to help them survive and colonize the gut....

Inexpensive Disposable Hydro-Jet Capsule Robot for Gastric Cancer Screening in Low-Income Countries

Summary Gastric cancer is the second leading cause of cancer death worldwide. While screening programs have had a tremendous impact on reducing mortality, the majority of cases occur in low and middle-income countries (LMIC). Typically, screening for gastric and esophageal cancer is performed using a flexible endoscope; however, endoscopy resources...

Real-time Detection of Position and Orientation of Wireless Endoscopy Capsule using Magnetic coupling

SummaryVanderbilt researchers have developed a new system to detect the position, orientation, and pressure exerted on surrounding tissues of a wireless capsule endoscopy device. Magnetic coupling is one of the few physical phenomena capable of transmitting actuation forces across a physical barrier. Magnetic manipulation has the potential to make...

Flexible Instrument with Pre-curved Elements for Surgical Tools

SummaryVanderbilt researchers have developed a novel system for allowing surgical instruments to navigate around tighter corners and access difficult-to-reach areas in the body. This system uses pre-curved elastic elements added on to the existing instrument. Current surgical instruments are manufactured in a straight-line configuration, which means...

Local Magnetic Actuation for Obese And Pediatric Patients

SummaryResearchers in Vanderbilt University’s STORM Lab have developed a novel actuation system that uses magnetic coupling to transmit mechanical power across a physical barrier. This technology is particularly suited for use in minimally invasive surgical procedures for manipulating surgical instruments across tissue barriers.Challenges in Minimally...
