This technology uses combinations of materials with different electronic properties of micro-or nanometerscale grain size to create a memristive device (twoterminal, variable resistance circuit element). Amidst growing interest in memristors, this technology is one of the first to use composite materials, which make the memristive qualities of the material tunable.
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.
Dr. Fernando P. Polack, a leading international researcher in pediatric infectious diseases, has discovered a new prognostic to predict which infants are at high-risk for hospitalization caused by severe Respiratory Syncytial Virus (RSV) infections. The test measures a mutation in a single gene, along with a quantifiable environmental factor that confers susceptibility. The goal is to categorize infants most likely to benefit from preventative care.
A Vanderbilt engineering senior design team has developed a car seat safety attachment that detects if a child has been left unattended in a car seat and if the environment has become uncomfortably hot or cold. The system is designed with a graduated alarm system based on "alert states" that provides a combination of visual, tactile and audio alerts.
The overall lifetime colorectal cancer risk for Americans is 5.1%, thus screening is recommended for those over the age of 50. Currently, colonoscopies are the standard for monitoring colon cancer development, but are invasive. Therefore, a need exists for a minimally-invasive test that could measure colon cancer risk. Ideally, such a test would offer a straightforward, personalized recommendation on how to substantially reduce colorectal cancer risk. Researchers at Vanderbilt University have identified a test that can characterize colorectal cancer risk and recommend a strategy for risk reduction. Importantly, this test requires only a blood sample and information about a person's diet.
A Vanderbilt research group has discovered a diagnostic to identify patients with non-small cell lung cancer that would respond to MEK inhibitor therapies. This diagnostic indirectly measures loss of tumor suppressor activity by the protein LKB1. The traditional approach to determine MEK inhibitor sensitivity, which is measurement of LKB1 mutations, misses 50% of patients who would benefit from these drugs. This diagnostic measures expression of a small panel of genes to identify a larger population that is sensitive to MEK inhibition.
