Microplastic Abundances In The Guana River Estuary In Northeast Florida, Mckenna Keplinger Jan 2022

Microplastic Abundances In The Guana River Estuary In Northeast Florida, Mckenna Keplinger

Honors Undergraduate Theses

Plastic never fully disappears, but instead breaks into smaller pieces referred to as microplastics (< 5 mm length). Microplastics are common worldwide, and more studies are needed to understand the accumulation and diversity of microplastics found in various environments. In this study, six locations were sampled for one year in the Guana River Estuary, a partially impounded system with heavily urbanized headwaters. This study was conducted in conjunction with the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM NERR) and the Florida Fish and Wildlife Conservation Commission (FWC) at their water sampling stations. The objectives of this study were to investigate: 1) distribution patterns across sample sites over time, 2) the color, size, and shape of microplastics found, and 3) polymer composition. Water samples were collected from surface waters in 1-L bottles, with five replicates at each site. Sampling occurred once a month, at the beginning of each month from August 2020-August 2021. Samples were analyzed for abundance and characteristics of microplastics using a dissecting microscope and the polymer composition was determined using Fourier-transform infrared spectroscopy. No pattern was found in the distribution of microplastics from north to south or over time. Variations in plastic color, size, and polymer composition suggests that there are multiple sources of pollution into the Guana River Estuary.

Heterogenous Reduction Of Co2 Over Boron-Rich Alb2, Jose C. Berger Jan 2022

Heterogenous Reduction Of Co2 Over Boron-Rich Alb2, Jose C. Berger

Honors Undergraduate Theses

Evidence suggests that the recent drastic changes in the global climate have been caused by greenhouse gases, especially CO­2. As a result, scientists are aiming to develop processes that either minimize the production of these gases or convert them into products of higher value. To that end, the catalytic properties of a two-dimensional boron-rich material were investigated. Herein is reported that such a material can reduce CO2 into benzene, C3 species, and C4 species at relatively low temperatures (225-450 ℃) and pressures (0.38 MPa). Current data suggest that a low-temperature induction period (e.g., 225 ℃) …

Targeting L-Arginine Metabolism To Control Small Cell Lung Cancer Transformation, Robert L. Burns Jr. Jan 2022

Targeting L-Arginine Metabolism To Control Small Cell Lung Cancer Transformation, Robert L. Burns Jr.

Honors Undergraduate Theses

Cancer is known for its unregulated and mutagenic characteristics. The topic of targeting cancer by inhibiting the metabolic pathways it uses to thrive has been a focus of modern cancer research. Specifically, in lung cancer, the transformation from non-small cell lung cancer (NSCLC) to small cell lung cancer (SCLC) is a focus. This transformation often comes with a grimmer prognosis and reduced survival rate. This is primarily due to SCLC being resistant to epidermal growth factor receptor (EGFR) inhibitors. This frontline treatment for EGFR mutant NSCLC has shown to be quite effective until transformation to SCLC occurs. To further study …

Examining The Effects Of Synthetic Dye Yellow No. 5 (Tartrazine) Exposure On Mouse Neuro2a Neurons In Vitro, Jenna L. Farnum Jan 2022

Examining The Effects Of Synthetic Dye Yellow No. 5 (Tartrazine) Exposure On Mouse Neuro2a Neurons In Vitro, Jenna L. Farnum

Honors Undergraduate Theses

Yellow Dye No. 5, also known as tartrazine (TRZ), is widely used[1] and has an accepted daily intake (ADI) of 0-7.5 mg/kg of body weight per day[2]. Consuming TRZ dosages greater than the ADI can lead to reduced levels of antioxidant enzymes in the brain, chromosomal alterations, or neuronal dendritic changes, [3, 4] which can result in oxidative stress, impaired neuronal functioning and potential mutagenic effects. Within the ADI, there have been observed reductions of the copper zinc superoxide dismutase-1 (SOD1) enzyme levels.[5]We hypothesize that TRZ interacts pre-translationally inside the cell, resulting in the reduction of SOD1 mRNA. …

Mediation Analysis Of A Broader Conceptualization Of The Three-Step Theory Of Suicidality, Ana V. Garcia Villasana Jan 2022

Mediation Analysis Of A Broader Conceptualization Of The Three-Step Theory Of Suicidality, Ana V. Garcia Villasana

Honors Undergraduate Theses

Unsatisfactory results for the aim of reducing suicide rates have motivated the creation of new models to predict suicide, such as the ideation-to-action framework, which focuses on differentiating those with suicidal ideation and those who attempt suicide. The most recently published theory on the ideation-to-action framework is the Three-Step Theory (3ST). Step 1 proposes that the combination of pain and hopelessness causes suicidal ideation, step 2 proposes that ideation increases when pain and hopelessness surpass connectedness, and step 3 proposes that strong suicidal ideation escalates to action when the person has the capacity to attempt suicide. The theory’s concepts are …

The Evolution Of Racial And Ethnic Disparities In Health Outcomes, Megan T. Hoang Jan 2022

The Evolution Of Racial And Ethnic Disparities In Health Outcomes, Megan T. Hoang

Honors Undergraduate Theses

Health disparities between different racial/ethnic groups in the United States are substantial. When reviewed across an extensive body of literature, these disparities have been demonstrated to persist even when socioeconomic status, geographic region, health conditions, treatment methods, and patient access-related variables are controlled. This ultimately leads to higher mortality rates among minority patients, making disparities in health a highly prevalent issue. However, the literature suggests that while racial and ethnic disparities in health have been widely examined, research documenting the evolution of these changes over time is lacking. This motivates the research questions: (1) How has the impact of racial …

Investigation Of Catalysis Of Nitration By Cytochrome P450s, Lannika Johnson Jan 2022

Investigation Of Catalysis Of Nitration By Cytochrome P450s, Lannika Johnson

Honors Undergraduate Theses

TxtE is a protein related to cytochrome P450 enzymes, which catalyze a number of reactions that typically involve oxygen and not nitrogen. It has been discovered that TxtE can nitrate tryptophan through an unusual reaction in which it uses nitric oxide (NO) as a nitrogen donor to install the nitro group despite NO typically being considered toxic to bacteria. This project will determine if all cytochromes P450 can catalyze nitration as long as they are given NO. This will have an impact on understanding drug delivery and metabolism for which nitration is important.

Investigating The Relationship Between Biological Age And Mutant Huntingtin Misfolding, Ratnesh Kesineni Jan 2022

Investigating The Relationship Between Biological Age And Mutant Huntingtin Misfolding, Ratnesh Kesineni

Honors Undergraduate Theses

Huntington Disease (HD) is an autosomal dominant neurodegenerative disease caused by an expansion of a CAG trinucleotide repeat tract in the huntingtin (HTT) gene. This CAG tract expansion causes production of mutant HTT (mtHTT) protein, which misfolds and forms inclusions in the brain that accumulate with age. Misfolded mtHTT aggregates have been linked with increased cell death in neuron cell culture, leading to speculation that mtHTT aggregates cause cell death. However, there are mouse lines that have robust mtHTT inclusion deposition, but no HD-like signs or neurodegeneration. Furthermore, neuronal HD cultured cells with inclusions were found to be …

Bioprospecting For Improved Floral Fragrance In Wild Sunflower, Jason Anandappa

Honors Undergraduate Theses

The cultivation of crop sunflower or Helianthus annuus is a 20 billion USD industry globally. Crop wild relatives of H. annuus have a long history of being used to breed improved traits into cultivated varieties. Cultivated H. annuus is not known to have a pleasant aroma, and at times seed yield is limited by pollination services, particularly in the production of hybrid seed. Improved floral fragrance could improve pollinator attraction and would add value to ornamental sunflowers in the context of the cut-flower industry. If volatile organic compounds that together generate favorable scents are present in wild Helianthus species, they …

Emotional Neglect In Childhood And Attachment Anxiety In Adult Relationships As Predictors Of Social Networking Addiction, Latasha N. Mcdowell Jan 2022

Emotional Neglect In Childhood And Attachment Anxiety In Adult Relationships As Predictors Of Social Networking Addiction, Latasha N. Mcdowell

Honors Undergraduate Theses

This study investigated the relationship between childhood maltreatment and social networking addiction to determine if it was mediated by anxious-avoidant attachment. It was hypothesized that the presence of an anxious-avoidant attachment pattern developed as a result of childhood maltreatment would mediate the correlation between anxious-avoidant attachment and social networking addiction. This would mean that participants who developed an anxious-avoidant attachment style due to childhood maltreatment would use social media in unhealthy ways. To measure childhood maltreatment, the Adverse Childhood Experiences scale (ACE) was used. The Experiences in Close Relationships-Revised scale (ECR-R) was used to measure anxious-avoidant attachment. Finally, social networking …
