Development And Ex Vivo Characterization Of Enteric Coated Chitosan Beads For Crohn’S Disease Management, Craig Mendonca

Drug delivery is the process of transporting a drug to its site of action. It includes controlled delivery, where the drug is released at the tissue in a regulated manner. Additionally, it includes targeted delivery, where the drug is aimed at a specific tissue or region to avoid unwanted side effects (that would occur if the drug were distributed throughout the body). A cellulose acetate phthalate coated chitosan bead was developed as a formulation for controlled and targeted release of dexamethasone to the ilium and colon. This formulation was determined to be effective in delaying dexamethasone release until the formulation …

Modeling And Analyzing An Optogenetic System For Photoactivatable Protein Dissociation, Anvin Thomas, James Schaff

Computational modeling of cell-cell interactions can grant clues and can answer questions about an experiment, especially for observations about binding interactions and kinetics. This approach was used to investigate an interaction between a light-oxygen-voltage (LOV) domain and an engineered protein called Zdark (Zdk). The LOV domain is membrane-bound while Zdk is cytosolic. The LOV domain and Zdk bind strongly in dark (Kd 26.2 nM), and weakly upon exposure to blue light (Kd > 4 μM). Total internal reflection fluorescence (TIRF) images are acquired of Zdk, the fluorescent species bound to a mCherry tag, and the loss of fluorescence is …
Is Concussion-Related Sleep Disturbance Present After Return To Play In College Athletes?, Alexander Gallaer
Is Concussion-Related Sleep Disturbance Present After Return To Play In College Athletes?, Alexander Gallaer
Honors Scholar Theses
As one of the most commonly experienced symptoms, the ramifications of sleep disruption as a result of concussion are potentially great, yet widely unexplored. Particularly troublesome is murky data regarding the length of sleep disruption following a concussion. By analyzing self-reported sleep data via the Pittsburgh Sleep Quality Index, this study seeks to investigate potential differences in sleep quality between injured college athletes 40 days after they have been cleared to play and matched controls. Data was analyzed using ANOVA analysis as well as Pearson correlation. No significant differences were found in sleep quality between groups, nor was there a …

The Ush2a Gene: An Analysis Of Ultrasonic Vocalizations In A Mouse Model Of Usher Syndrome Type 2, Kiana R. Akhundzadeh
Honors Scholar Theses
Usher syndrome type 2 is a complex autosomal recessive genetic disorder that is characterized by moderate to severe congenital sensorineural hearing loss, the onset of retinitis pigmentosa in the second decade of life, and in some cases, vestibular dysfunction. Mutations in the USH2A gene account for 85% of cases of type 2. The USH2A gene is responsible for encoding the protein usherin, which has an important role in the development and function of inner ear hair cells and retinal photoreceptors. Until recently, it has been believed that carriers of the USH2A mutation were phenotype free. However, recent data has suggested …

The new gene editing system CRISPR/Cas9, composed of a complex composed of a guide RNA and the Cas9 endonuclease, promises to revolutionize biological research and potentially allow clinicians to directly modify patient DNA in vivo. While its applications in the treatment of genetic diseases and in modifying immune cells for immunotherapy are currently being explored, CRISPR/Cas9’s potential utility as a modular system for targeting tumor-specific mutated sequences has not as of yet been explored. While CRISPR/Cas9 is specific enough to target small insertions and deletions or gross chromosomal rearrangements, it is not specific enough to reliably restrict editing to …
