Abstract Phage therapy and antibiotics have been used in treating bacterial infections for nearly a century. However, bacterial mutations over time have allowed bacteria to advance in fitness and, in turn, resistance to these treatments. In this experiment we evolve phage-resistant bacteria to observe the mutations present on a genomic level. Pairing these observations with …
Abstract Dancers are often under pressure to maintain a lean physique; therefore it is common to observe unhealthy dieting behaviors leading to inadequate caloric intake and protein (PRO), which may negatively alter body composition (BC). PURPOSE: To assess collegiate dancers’ dietary intake, BC, resting metabolic rate (RMR), and total sleep (TS) following a 6-week PRO …
Autism Spectrum Disorder (ASD) is a developmental disability characterized by sensory and communication deficits. Recently, diagnosis of ASD has increased, and it is now estimated to affect 1 in 68 children. The symptoms of autism begin to appear during the first three years of life, which coincides with the development of learning ability and a …
Abstract The distribution of vector-borne diseases such as Zika virus continues to expand, leading to epidemics across a variety of geographical locations, but monitoring the spread of these diseases for public health purposes is made difficult by a lack of instrumentation. With the assay we are developing and testing, there is no need for special …
Observations of exoplanets, planets outside of our solar system, have exploded in the last 20 years, to the point where we know now of thousands of exoplanet systems. One of the great mysteries to come out of these discoveries has been the great diversity in types of planetary systems seen. Up until we started discovering …
The Galápagos Islands are home to many diverse species, but not all have diverged as extensively as Darwin’s finches. What could be preventing diversification in the Succinea land snails?
Abstract:Cupriavidus necator, a Gram-negative soil bacterium, will be characterized using AC-based dielectrophoretic microwells. A crossover frequency will be found for the bacterium in buffer as well as the bacterium in different metal solutions and different concentrations. Once the crossover frequency has been observed and the process has been repeated to ensure repeatable values, the bacterium …
Stem cells play an important role in regenerative medicine because of their ability to proliferate into various cell types. Current work focuses on murine mesenchymal stem cells (MSCs) differentiating into tenogenically differentiated cells upon exposure to a growth factor TGFβ2. During the course of their differentiation on treatment, MSCs are observed to exhibit different phenotypical and genotypical changes accounting for their change in electrophysiological make-up, i.e., the capacitance and permittivity of both the cell membrane and its interior. In this study, murine MSCs are characterized using dielectrophoresis (DEP), a non-labeling, non-destructive electrokinetic technique using a crossover frequency method. DEP is known to be able to detect subtle changes within the cell. Studies were performed on both untreated and treated (treated with growth factors differentiating into tenogenically modified MSCs) murine MSCs; the treated MSCs were treated on a time scale of days 1, 3, and 7. The results showed that tenogenically modified MSCs differed significantly in their electrical properties and could be distinguished from the untreated MSCs as early as 3 days into treatment.
The initial discovery We are investigating the potential of protein toxins naturally produced by Saccharomyces cerevisiae (Brewer’s/Baker’s yeast) to inhibit the growth of the human pathogen Candida glabrata. These toxin producers are known as killer yeasts to those who study them. We have tested over 15,0000 interactions between our killer yeasts and 130 isolates of …
By improving current bioremediation techniques for the removal of trichloroethylene from groundwater we can improve efficiency, improve safety, and treat spills closer to the source.
