Patel, Earlissa Tucker, Rishubh Madaboosi, Mehtab Singh

Undergraduate Student Symposium

In 1915, Frederick William Twort and Felix d’Herelle discovered bacteriophages (phage), viruses that kill bacteria. As this was prior to the discovery of antibiotics, their work led to early development of phage therapy, treatment that involves the use of phage to selectively kill bacterial. Today, phage therapy provides an alternative to antibiotics especially by targeting specific pathogens that are normally resistant to multiple treatments. Even with its ability to alleviate the antibiotic-resistant problem, the vast majority of phage remains uncharacterized. Therefore, it is important to expand bacteriophage discovery-based and genome characterization research. Through the SEA-PHAGES (Science Education Alliance – Phage …

Undergraduate Student Symposium

Waterhyacinth is an invasive floating plant that rapidly grows across aquatic environments, creating dense mats that disrupt ecosystems like the Everglades and Lake Okeechobee. Our prior observations showcased that waterhyacinth supports different fish and invertebrate species assemblages than the native plant species. More invertebrates, especially amphipods, are found in the roots of waterhyacinth than its native equivalent, pennywort. To determine what causes these patterns, we asked four different questions: whether waterhyacinth has a greater root surface area than pennywort, whether fish preferred native plant environments, whether dissolved oxygen (DO) levels were comparable, and whether predation rates were similar. Surface area …

Effect Of Dopamine On Nlrp3 Inflammasome Activity And Thiol Metabolites In Human Thp-1 Macrophages, Grace K. Wong, Emily H. Guirguis

Undergraduate Student Symposium

Neuroinflammation plays an important role in aging and neurological disorders across the lifespan and the NLRP3 inflammasome has been closely linked to the progression of neurodegenerative diseases and is a potential target for therapy. The neurotransmitter dopamine regulates production of inflammatory cytokines in an age-dependent manner and in neurons dopamine is stored in a complex with ATP and both are released during neuronal activity. ATP promotes NLRP3 inflammasome activity via the P2X7 receptor. However, the combined influence of dopamine and ATP on inflammasome activity has not been previously investigated. The goal of this study was to examine lipopolysaccharide (LPS)-induced NLRP3 …

Effects Of Reproductive Experience On Cognitive-Behavioral Outcomes In Mouse Models Of Alzheimer's Disease And Related Dementias, Chana Vogel, Esperanza Barrios, Ariana Hernandez, Natalia Noto

Undergraduate Student Symposium

Dementias, including Alzheimer’s disease and vascular dementia, are devastating conditions lacking safe and effective treatments. Despite the striking sex/gender difference in the prevalence of dementia, few studies have investigated sex-specific factors that may influence the greater risk and faster progression of disease in females. These factors include but are not limited to prior pregnancy and motherhood. Women with children have slower rates of cognitive decline and lower risk for developing mild cognitive impairment or dementia than women with no children. However, other studies have reported mixed results, suggesting that the influence of reproductive/maternal experience may depend on an individual’s number …

Methyl Group Substituent Effect On The Basicity Of Meso-Substituted Porphyrins, Krisha Patel, Rochelle Avezki, Tej Chaudhari, Alex Arshavsky

Undergraduate Student Symposium

Titration studies of three freebase porphyrins (meso-tetra-2-methylphenyl, meso-tetra-3-methylphenyl, meso-tetra-4-methylphenyl) were carried out to determine the corresponding basicity in solution with a nonpolar solvent (toluene). The differences in the porphyrin structure lie within the position of the substituents, specifically the position of the methyl group. In each trial, protonation of the porphyrins was reached through the repeated addition of trifluoroacetic acid (TFA). In examining the protonation of these different isomers, the pKa values were determined through a spectrophotometric analysis. The apparent pKa values were found using the modified Henderson-Hasselbalch equation.
