Improving The Palatability Of Colonoscopy Preparations, Phuong Anh Hoang Nguyen, Darnell Leon Cuylear, Heather Elizabeth Canavan Nov 2018

Improving The Palatability Of Colonoscopy Preparations, Phuong Anh Hoang Nguyen, Darnell Leon Cuylear, Heather Elizabeth Canavan

Shared Knowledge Conference

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. The most reliable screening method of CRC is a colonoscopy which requires a 4-Liter polymer with electrolytes preparation. Two in five patients are non-compliant to their colonoscopy schedules, with many patients who abstain reporting refusal due to significant discomfort associated with this preparation. Furthermore, there are distinct gender differences in the tolerance of colonoscopy preparations in male and female populations. We hypothesize the differences in clinic are a result of toxic effects of the drug associated with poor mixing by individual patients. PEG, the drug, …

L-Serine Reduces Reactive Oxygen Species Yield In Cisplatin Treated Zebrafish Utricles, Satya A. Moolani, Elvin Irihamye, Jerry D. Monroe, Michael E. Smith Nov 2018

L-Serine Reduces Reactive Oxygen Species Yield In Cisplatin Treated Zebrafish Utricles, Satya A. Moolani, Elvin Irihamye, Jerry D. Monroe, Michael E. Smith

Posters-at-the-Capitol

Cisplatin is a chemotherapy compound effective against a variety of cancers. However, it can act as an ototoxin and cause hearing loss by promoting reactive oxygen species (ROS) production in auditory tissues. The antioxidant amino acid, L-serine has been hypothesized to lower levels of cisplatin-mediated ROS. In this project, we investigated whether L-serine can reduce cisplatin-mediated ROS production in auditory tissue and potentially act as an otoprotectant during cisplatin chemotherapy. We used a zebrafish utricular tissue culture system and fluorescent ROS indicator dye to spectrophotometrically measure if L-serine could decrease reactive oxygen species levels in cisplatin-treated tissues. We found that …


Polyrotaxane Variants And Their Effects On The Cholesterol Efflux In Patients Suffering From Niemann Pick Type C, Sydney Smith, Zach Struzik, David Thompson Aug 2018

Polyrotaxane Variants And Their Effects On The Cholesterol Efflux In Patients Suffering From Niemann Pick Type C, Sydney Smith, Zach Struzik, David Thompson

The Summer Undergraduate Research Fellowship (SURF) Symposium

Niemann Pick type C disease (NPC) is a rare lysosomal storage disorder characterized by a progressive accumulation of cholesterol in the late endosomal/lysosomes compartment leading to cellular dysfunction and organ failure. Symptoms include ataxia, dysarthria, cognitive dysfunction, and seizures. Although average life expectancy is below 20, there are no FDA approved treatment available making it a serious unmet medical need. Clinical trials with 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD) has shown promise in cholesterol normalization within NPC cells. However, HP-beta-CD treatment has been shown to cause ototoxicity in NPC patients at high dosages. Supramolecular complexes known as polyrotaxanes have been synthesized in hopes of …


Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra Aug 2018

Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra

The Summer Undergraduate Research Fellowship (SURF) Symposium

Microglia are the brain’s resident immune cells that are responsible for maintaining homeostasis in healthy conditions. During injury or infection, resting microglia get activated and produce pro-inflammatory cytokines such as IL-1b, IL-1a, IL-6, etc. along with reactive oxygen species like nitric oxide (NO) to combat neuroinflammatory diseases such as Alzheimer’s disease (AD). Inflammation is characterized by the activation of resident-immune cells in the brain called microglia that respond to the eat-me signals released by the toxic amyloid beta peptides as well as the dying neurons in the microenvironment. Recent studies have shown that activated microglia induce neuronal death by secreting …


The Effect Of The Oxytocin Hormone In Cocaine Addicted Rats Suffering From Abstinence Syndrome, Juan Padilla Jun 2018

The Effect Of The Oxytocin Hormone In Cocaine Addicted Rats Suffering From Abstinence Syndrome, Juan Padilla

The International Student Science Fair 2018

This study aimed to understand the effects of oxytocin in cocaine-addicted rats to prove its ability to help recovering drug addicts overcome the extreme anxiety and craving that makes them relapse during their rehabilitation.
