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.

Parasites In Flight: Toxoplasma Gondii Genotypes In South Florida Birds, Ava Barrasso, Katherine Hirt, Kaitlin Whalen, Shree Diora, Adhiraj Katoch, Aansi Patel

Undergraduate Student Symposium

Toxoplasma gondii is a zoonotic parasite that significantly impacts human and wildlife health. Often associated with domestic cats, avian hosts also contribute to the parasite's persistence in global ecosystems. This research investigates the strain diversity of T. gondii found within South Florida birds. Florida is an avian biodiversity hotspot along two migratory flyways and therefore presents unique opportunities to detect novel and/or virulent genotypes that may present health risks to humans. These risks are increasing with environmental factors (e.g. urbanization and climate change) that facilitate pathogen transmission between feral and domesticated animals, and susceptible human populations. Our approach consists of …

Pecking At Protozoan Parasites: Pcr Diagnostics Of Toxoplasma Gondii In South Floridian Birds, Senia Bu, Donna Huynh, Sridevi Gundimeda, Samhita Doranala, Madeline Hsu, Valentina Cevallos

Undergraduate Student Symposium

Toxoplasma gondii is a protozoan parasite whose prevalence and transmission remain underexplored in wildlife, especially in birds. This is a crucial gap since birds can serve as pathogen reservoirs (facilitating transmission to humans and other animals) and because T. gondii’s prevalence in wildlife (e.g. birds) helps illuminate its environmental distribution. Thus, characterizing T. gondii in local avian communities can help us assess and mitigate risks to the health of humans, pets, agricultural animals, and endangered wildlife. This study investigates T. gondii prevalence in South Florida’s diverse avian species. We obtained tissue samples from >100 birds by dissecting carcasses provided …

The growing international concern for the rise in drug-resistant microorganisms has driven research to determine approaches that will keep microbes from developing further immunological adaptations. Photosensitizers are molecules activated by light that produce reactive oxygen species (ROS) lysing and causing cell death in structures of microbes and in diseased mammalian cells. The photosensitizers applied in this experiment are meso–Tetra(N–methyl–pyridyl)porphine tetrachloride isomers. Three variations of the nitrogen placement were used to understand the interactions with the bacterial cell …

Playing Stereoscopic Video Games Enhances The Precision But Not The Accuracy Of Depth Perception, Charlene Li, Nada Bleibel, Lara Cereminati, Yingzi Luo, Betty Z. Li Ph.D., Dennis M. Levi Ph.D., Sandy W. Chat

Undergraduate Student Symposium

Purpose. We recently reported that playing immersive video games in a three-dimensions (3D) environment boosts stereo vision in young adults with normal vision. Here we asked whether the improvement in stereoscopic acuity (precision) was the result of a reduced disparity pedestal, as indicated by a decreased subjective depth bias (accuracy).

Methods. Twenty-one university students with normal visual acuity and stereoacuity were recruited. All of them had limited previous video game experience, and none had ever played 3D video games. Participants were required to play stereoscopic 3D video games for a total of 40 hours, 2 hours per session, over 4-5 …

Predictive Toxicological Analysis Of Novel Prostate Cancer Drug, Dani Sheil

Undergraduate Student Symposium

Prostate cancer is the second-leading cause of cancer-related death in men in the United States, claiming approximately 1 in 44 lives. While novel cancer therapies aim to selectively target cancer cells, minimizing damage to healthy tissues, these treatments can still cause significant side effects. The drug discovery process remains costly and time-intensive, with only 10-20% of compounds making it from clinical trials to market, often due to toxicity issues that arise during later-stage testing. To address this, computational methods in predictive toxicology can expedite drug development by assessing potential toxic effects early, reducing costs and risks. In this study, we …

Psychedelic Substituted Phenethylamine Alters Human Neural Progenitor Cell Morphology, Proliferation, And Survival, Omar E. Saleh, Grace K. Wong, Chase A. Gonzales, Mark Apterman, Laury Pierre, Stacey Doret, Isaac Hai, Travis J.A. Craddock

Undergraduate Student Symposium

Examining how psychedelic substituted phenethylamines affect neural plasticity is key to understanding harms and potential medical implications of recreational drugs. The microtubule cytoskeleton has been proposed to modulate the effects of phenethylamines as a downstream effector and through scaffolding mechanisms. Microtubules play a crucial role in neurite outgrowth, protein transport, and synaptic stability in cells. Our group has shown that specific psychedelic substituted phenethylamines (25B-NBF, 25C-NBF, and DMBMPP) alter microtubule formation in a dose-dependent manner. As these phenethylamines limit microtubule capacities, they may impact cytoskeletal-mediated neural plasticity. This study’s purpose is to determine if substituted phenethylamines, 25B-NBF, 25C-NBF, and DMBMPP …

Reproductive Outcomes In A Mouse Model Of Alzheimer's Disease, Melanie Mendonca, Esperanza Barrios, Chana Vogel, Victoria Pulido-Correa

Undergraduate Student Symposium

Alzheimer’s disease (AD) is a devastating neurodegenerative disease lacking effective treatment. Despite women having 2x greater risk for developing AD, few studies have investigated the sex-specific factors that influence AD risk. Reports show a difference in the risk and progression of AD in parents and nonparents, suggesting motherhood may mitigate the risk and impacts of AD, but alternative explanations could play a role. For example, healthier and wealthier people may have more reproductive opportunities and less disease risk. Moreover, genes that alter disease risk could also modify fertility/fecundity, such as APOE4, a gene that increases both AD risk and fertility. …

Conversely, many antiepileptics affect glucose and lipid metabolism.

The nematode Caenorhabditis elegans (C. elegans) is a model organism suited for studying metabolic and neurological disorders, due to its genetic tractability, short life cycle, and conserved signaling pathways. Although previous studies have developed and used genetic and diet-induced obesity models in C. elegans, none …

Sgi-1027 Small Molecule Inhibits Dnmt And Promotes P21-Mediated Apoptosis Via Epigenetic Alterations In Sk-N-Sh Neuroblastoma Cells, Sadhna Seth, Anika Singh, Shyam Sundar Jaganathan Ph.D.

Undergraduate Student Symposium

Neuroblastoma is an aggressive childhood cancer originating from neural crest cells. Treatment for high-risk neuroblastoma includes chemotherapy. Emerging evidence indicates that DNMT inhibitor codenamed SGI-1027 may facilitate cell cycle arrest and induce apoptosis by modulating cell cycle regulatory pathways. Therefore, we hypothesize that SGI-1027 treatment could lead to apoptosis mediated cell death in SK-N-SH cells through the upregulation of p21 transcription.

This study investigated whether SGI-1027, a DNA methyltransferase inhibitor, causes DNA methylation and upregulation of p21 through a p53-independent pathway, which could lead to cell cycle arrest and intrinsic-pathway mediated apoptosis in SK-N-SH cells. To assess the effects of …

Solvent Effect On The Stabilization Of The Monoprotonated Species Of Tetraphenylporphyrin, Pablo Perez, Dani Sheil

Undergraduate Student Symposium

The protonation of Tetraphenylporphyrin (TPP) demonstrates unusual behavior where protonation causes only the formation of a diprotonated species. This behavior is due to a change in conformation leading to an unstable saddle deformation in which the monoprotonated species is highly unfavorable. The stabilization of the unfavored conformation in the monoprotonated intermediate species may be achieved by understanding the effects of different solvents on the protonation of TPP. This study was done to explore the protonation of TPP using Toluene Chloroform, and Dichloromethane using trifluoroacetic acid and chloroacetic acid to analyze the effects of the different solvents. Using a UV spectrophotometer, …
