Scientists at Vanderbilt have developed a sterile kit to collect blood cultures that results in substantially fewer contaminated cultures compared to the current standard of care for collecting culture specimens.
Vanderbilt researchers have developed a normally closed valve that is able to provide selective movement of small fluid quantities in a microfluidic device. The present microfluidic valve can be actuated using a simple rotating drivehead and mechanical support, greatly simplifying the valve design.
Vanderbilt researchers have developed a method to perform the Parahydrogen Induced Polarization (PHIP) based method of Signal Amplification by Reversible Exchange (SABRE) in aqueous media. This allows the resulting hyperpolarized molecules to be used for in vivo applications.
Vanderbilt researchers have developed a group of microfluidic organ-on-chip devices that include perfusion controllers, microclinical analyzers, microformulators, and integrated microfluidic measurement chips. Together, these devices can measure and control multiple organ-on-chip systems in order to model the multi-organ physiology of humans.
New everninomicin antibiotics including a potent bifunctional antibiotic natural product targeting two different and distant ribosomal sites are under development and can be readily produced using synthetic biology. Developing resistance to this bidentate antibiotic should be very difficult for pathogenic microorganisms.
This device is designed to assist physical therapists in collection of objective data during gait analysis, to facilitate appropriate assistive gait device prescription, to provide patients and therapists feedback during gait training, and to reduce wrist and shoulder injuries with cane usage.Currently gait characteristics are "measured" in a clinic-based atmosphere. This has two limitations: (i) subjective allocation of "measures" of gait characteristics and (ii) limited data based on trials in the clinic ONLY. What this technology is designed to do is achieve freedom from both of these limitations. The measurements are objective and numerical values (force etc.) and the clinic could provide the cane to the user for obtaining a much more extensive data set including use during normal life activities at home etc.
New compounds developed at Vanderbilt demonstrate a unique mechanism of broad spectrum activity to stymy antibacterial resistance. The compounds are particularly useful in chronic infections where long term antibiotic therapy fails, because it specifically kills "small colony variants" -- the bacteria that have developed resistance mechanisms. These compounds show promise in treating Methicillin-resistant S. aureus (MRSA), Bacillus anthracis (anthrax), and in overcoming difficult-to-treat infections in bone in cystic fibrosis patients. These compounds could be combined with new (and old) antimicrobial drugs to outwit resistant bacterial infections.
LumaSiL is a low-level light therapy (LLLT) producing device which aims to accelerate wound healing and reduce the incidence of infection in diabetic foot ulcers (DFUs). There is no treatment option using this technology that actively encourages diabetic foot ulcer healing, complements current procedures, and maintains patient compliance. Complications like infection often require the need for surgical intervention such as lower-extremity amputation. Previous studies have shown that exposing wounds to dose-specific levels of light can reduce wound size and promote healing. Incorporated into a standard of care, the total-contact cast, this device transfers LED light from a power source to the wound site in order to introduce an active healing component for diabetic foot ulcers.
Vanderbilt researchers have developed a system that corrects for compressional effects in ultrasound data during soft tissue imaging. The system uses tracking and digitization information to detect the pose of the ultrasound probe during imaging, and then couples this information with a biomechanical model of the tissue to correct compressional effects during intraoperative imaging.
