E,E-Farnesol Inhibits Swarming Motility In Burkholderia Cepacia Through Rhamnolipid Production, Stephanie E. Nicholls, Alayna N. Sanderson, Andrea P. Schwartz, Lauren E. Ward, Jessica N. Weisensee, Molly Yandrofski, Tracy L. Collins

The Research and Scholarship Symposium (2013-2019)

Burkholderia cepacia and Candida albicans both exhibit cell-to-cell communication through the use of quorum-sensing molecules (QSM) known as autoinducers. E,E-farnesol is a QSM produced by C. albicans which regulates its conversion from yeast to mycelium. Because there is a positive correlation between the presence of B. cepacia and C. albicans in the lungs of individuals with cystic fibrosis (CF), we examined whether E,E-farnesol had an effect on swarming motility in B. cepacia. Swarming motility was inhibited when B. cepacia was exposed to 250 µM of E,E-farnesol. In addition, there was a 26.8% decrease in rhamnolipid production when cells were grown …

Effects Of Antiepileptic Medications On Bone Density In Individuals With Intellectual And Developmental Disabilities, Carly R. Gregory, Hannah L. Stedge, Robyn K. Brandenburg

The Research and Scholarship Symposium (2013-2019)

Individuals with intellectual and developmental disabilities (IDD) are commonly prescribed antiepileptic drugs (AEDs) to manage seizures, manage behavior, and stabilize mood. Though research has been done on the effects of antiepileptic medications in patients with epilepsy, little study has been done on the persons with intellectual and developmental disabilities population. After surveying IDD patients with a history and current use of AEDs on osteoprotective behaviors, we were unable to use SPSS due to incomplete surveys and low sample sizes. However, we were still able to analyze for common themes, and we found that the most prevalent use of AEDs was …

Investigation Of The Effects Of Growth Environment On The Ferric Reducing Antioxidant Power Of Selected Plant Species, Denise S. Simpson, Marshall C. Johnson, David T. Bancroft, Robert L. Paris

The Research and Scholarship Symposium (2013-2019)

Metabolism within the human body creates multiple oxidant by-products. These oxidants may cause cell injury, damage to DNA, and other complications leading to the development of chronic disease. Antioxidants are important dietary components which defend against oxidative damage by scavenging the oxidant by-products. Research has shown that diets rich in antioxidants offer protection against various chronic diseases.

The goal of this research is to determine the effects of varying growing conditions on the production of antioxidants, and to ultimately find the best possible plant-growth environment for maximum production of antioxidants. Each plant was grown under three different environmental conditions; positive, …
