Catalase Activity In The Presence Of Pure Flavonoids, Emily Weems, Erika L. Doctor

Student Publications and Presentations

Catalase is an enzyme which catalyzes hydrogen peroxide into water and molecular oxygen. Flavonoids inhibit catalase, which allows for a buildup of hydrogen peroxide in our bodies that is important when we are sick. Pure flavonoids, like those found in colorful fruits and vegetables, will inhibit catalase by reducing the enzymes’ ability to break down hydrogen peroxide. The pure flavonoids that we looked at are hesperidin and naringenin, found in citrus fruits, and quercetin, found in vegetables like onions and hot peppers. Plant flavonoids are seen to inhibit catalase but are found bounded to compounds like sugars while pure flavonoids …

Effects Of Sublethal Bisphenol A On Planarian Phototaxis, Alexis Galindez, Emily Pintilie, Kevin Sosa, Cassandra S. Korte

Student Publications and Presentations

Bisphenol A (BPA) is a common plastic found in many consumer products, including water bottles, food containers, and toys. Previous research shows BPA is an environmental contaminant with potential neurotoxic effects, including nociceptive behaviors in planaria flatworms. Planaria flatworms, such as Girardia dorotocephala, are valuable model organisms for studying neurotoxicity due to their simple but well-characterized nervous systems and measurable phototaxis or light response behaviors. Earlier experiments in our lab demonstrated that BPA concentrations of 1 ppm and higher caused high mortality and reduced movement. We were thus unable to measure phototaxis behavior at this higher concentration. This study investigated …

Planarian Exposure To The Herbicide 2,4- Dichlorophenoxyacetic (2,4-D), Emily Pintilie, Alexis Galindez, Kevin Sosa, Cassandra S. Korte

Student Publications and Presentations

Widespread use of pesticides such as 2,4-dichlorophenoxyacetic acid (2,4-D) raises serious concerns about their effects on non-target aquatic organisms. In vertebrates, 2,4-D has been associated with neurotoxic outcomes such as impaired motor function and altered neurotransmitter activity. Planarians offer a valuable system for toxicological studies due to their well-characterized nervous system, regenerative capacity, and measurable behavioral responses. This study investigates the neurotoxic effects of 2,4-D exposure in the planarian species, Girardia dorotocephala, including assessment of nociceptive behaviors, survival rate, and phototactic responses. Worms were exposed to various concentrations of 2,4-D (0–100 mg/L) over multiple time points. Nociceptive responses such …

From Plastics To Pathways: Phthalates, Oxidative Stress, And Nervous System Function In Planaria, Destiny M. Perez, Cassandra S. Korte

Student Publications and Presentations

Phthalates are widely used chemicals added to plastics to increase flexibility and durability. Because they are not chemically bound to products, they can leach into the environment and contribute to human exposure through food packaging, plastic containers, and hygiene products such as lotions, shampoos, and fragrances. This widespread exposure has raised public health concerns because many phthalates are linked to endocrine disruption and have been associated with reproduction, developmental, metabolic, and neurological disruption. To investigate how phthalates may impact nervous system function, planarian flatworms will be used as a toxicology model. Planaria will be exposed to phthalates and then tested …

Circadian Genes In Fruit Flies: What They Teach Us About Human Sleep And Health, Laney Wilson, Mia Gonzalez, Kimberly Rowland

Student Publications and Presentations

Circadian rhythms are cycles developed internally that influence the behavioral and physiological changes that happen daily. They occur in organisms as diverse as humans and fruit flies. They are the product of “clock” genes that set the rhythm and tune them in response to changes in the ambient light. In the present study, we aimed to determine the contribution of functional clock genes to the circadian regulation of movement of the fruit fly Drosophila melanogaster. An equal number of wild-type flies (n = 5) and clock-mutant flies (n = 5) were placed in an incubator for 1 week to allow …

2020-Current year OA Pubs

OBJECTIVES: Children with differentiated thyroid cancer (DTC) often present with lung metastases but historically have good outcomes. Radioactive iodine (RAI) is commonly used to treat these children. Given the rarity of this condition, little evidence detailing long-term outcomes and risk of radiation pneumonitis exists.

METHODS: We conducted a retrospective analysis of patients < 20 years old who received RAI for DTC lung metastases between 1973 and 2018. Disease-free survival (DFS) was calculated from diagnosis to last follow-up. Overall survival and rates of acute and late radiation pneumonitis were determined by chart review and obituary searches.

RESULTS: Sixteen patients met eligibility criteria. Fourteen presented with thyroid, nodal, and lung disease; one presented with thyroid and nodal disease with nodal and lung recurrence; and one presented with thyroid-only disease with nodal and lung recurrence. All patients underwent thyroidectomy, 10 underwent neck dissection, and four underwent …

Sediment characteristics such as grain size, pH, and nutrient/sulfide concentrations can influence seagrass health and growth, but the relative importance is unclear. This study investigated the relationship between sediment characteristics and the performance of the seagrass Halodule wrightii across multiple different types of sediments found within the IRL in order to identify ideal sediments/locations …

Finding Jaws: Dna Barcoding Shark Cartilage To Identify Species, Kenna Peters

Ocean Engineering and Marine Sciences Student Publications

Elasmobranchs (sharks and rays) are vital keystone predators that help regulate the health of marine ecosystems, and some of the largest and most wide-ranging fishes in the ocean1. Elasmobranch identification is difficult due to morphological similarities between species, and the high risk of encountering cryptics. These are evolutionarily distinct, but physically identical to more common taxa, and can only be identified using genetics. Misidentification is a major obstacle to shark science, especially considering new data showing that >70% of all elasmobranchs have been lost in the past 50 years, and many sharks are now shifting ranges in response to global …

Words That Work: Healthcare Providers’ Acceptability Of Aba Terminology, Marisa A. Hurlock

Thesis Projects

Effective collaboration between behavior analysts and healthcare providers depends on a shared understanding. This study explored how healthcare professionals perceive technical versus plain-language ABA terminology. Healthcare providers (n = 44) rated 10 common ABA terms and their plain-language counterparts across clarity, acceptability, comfort, and likelihood of use. In addition, participants completed a paired-choice procedure in which they selected their preferred terminology for each term pair. Plain-language terminology was generally rated more favorably across all four dimensions and was preferred by approximately 70.6% of respondents. However, this pattern was not consistent across all terms, as several technical terms (e.g., negative …

Assessing Developmental Neurotoxicity Due To Pyrethroid Insecticide Exposure In C. Elegans, Katharine Boyd, Timothy A. Crombie

Biomedical Engineering and Sciences Student Publications

Pyrethroids are a type of insecticide widely used in agriculture and public health programs. These insecticides disrupt neuronal signaling in target insects through voltage-gated sodium channels and have been linked to cardiovascular and neurological disease in humans.The nervous system of the nematode Caenorhabditis elegans is fully mapped, and specific behavioral circuits can be tested, making it a powerful model for studying neurotoxicity. Because the primary target of pyrethroids is not conserved in C. elegans, secondary mechanisms of pyrethroid neurotoxicity can be identified by testing whether specific behavioral circuits are affected.

Photochemical Activation Of Cyanine-Based Nanogels For Controlled Drug Delivery, Presley Clary

Chemistry and Chemical Engineering Student Publications

Cyanines are highly conjugated molecules with useful properties, such as ease of aggregation and fluorescence. In this project, they were incorporated into an acrylamide-based nanogel made through organic synthesis to exploit these properties for controlled drug delivery. Exposing the nanogel to nearinfrared (NIR) light causes it to react with reactive oxygen species (ROS), forming an unstable intermediate. The intermediate splits into two fragments, releasing the nanogel's cargo.1 The cargo, temozolomide, is an alkylating agent which can be used to disrupt the DNA of cancer cells.
