Effects Of Dietary Perfluorobutane Sulfonate (Pfbs) On Adipose Tissue, Hannah Olofintuyi, Eric Gato Jan 2026

Effects Of Dietary Perfluorobutane Sulfonate (Pfbs) On Adipose Tissue, Hannah Olofintuyi, Eric Gato

Honors College Theses

Per- and polyfluoroalkyl substances (PFAS) are chemical substances used in a variety of industrial applications and consumer products. Perfluorobutane sulfonate (PFBS) is often used as a replacement for the more harmful (Perfluoroalkyl sulfonate) PFAS chemicals that have been around longer. It is believed that PFBS does not remain in the body as long as other PFAS compounds; however, there is a rising concern that it has the potential to cause damage to human health. This study focused on understanding how dietary PFBS exposure affects metabolism-related processes in adipose tissues in rats. To accomplish study objectives, Sprague Dawley rats were exposed …


Perinatal Inflammation And Oxidative Stress Alter Adult Rat (Rattus Norvegicus) Motor Behavior, Alexander Young Jan 2026

Perinatal Inflammation And Oxidative Stress Alter Adult Rat (Rattus Norvegicus) Motor Behavior, Alexander Young

Honors College Theses

Recent evidence in comparative animal models suggests that early life exposure to elevated inflammation (via LPS exposure) and oxidative stress (via acetaminophen exposure) may synergistically interact to alter typical neurodevelopmental trajectories, resulting in lasting effects on both behavior and gut-brain neurochemistry. The current study observed emotional and motor behaviors and collected fecal-boli to measure Tyrosine (TE) levels in male and female Long-Evans (Rattus norvegicus) rats. Subjects were either treated with [1] saline [2] lipopolysaccharide (LPS) to introduce an inflammatory state, [3] acetaminophen (APAP) to introduce oxidative stress, or [4] a dual-hit of both LPS + APAP on postnatal day (PD) …


Effects Of Perinatal Exposure To Lipopolysaccharide And Acetaminophen On Learning In Adult Long-Evans Rats, Lucy A. Sivils Jan 2025

Effects Of Perinatal Exposure To Lipopolysaccharide And Acetaminophen On Learning In Adult Long-Evans Rats, Lucy A. Sivils

College of Graduate Studies: Theses & Dissertations

The present study investigated the individual and combined effects of elevated perinatal inflammation, oxidative stress caused by acetaminophen (APAP) exposure, or elevated inflammation and oxidative stress on adult learning behaviors in Long-Evans rats. While prior studies have examined these factors independently, the combined effects of inflammation and oxidative stress via APAP exposure during early development on learning-related behaviors remain unexplored. The present research aimed to address this gap by the analysis of potential long-term neurodevelopmental consequences of lipopolysaccharide (LPS)-induced inflammation and APAP-induced oxidative stress. LPS, APAP, or LPS + APAP was administered during the perinatal period: postnatal days (PD) 9, …


Photodynamic Therapy Agents: The Power Of Mjöllnir To Eradicate Cancer, Sidney M. Hopper May 2023

Photodynamic Therapy Agents: The Power Of Mjöllnir To Eradicate Cancer, Sidney M. Hopper

Honors College Theses

After its discovery back in the 1900s, photosensitizers became a critical study for potential treatments and cures for medical issues, including cancer. It was discovered that porphyrins appeared to target and accumulate in proliferating cells, and to reach the cells, a certain wavelength of light with maximum absorbance associated with the porphyrin was necessary to achieve cell death. Photodynamic therapy involves making use of porphyrins or metalloporphyrins as activators when exposed to such light. When activated, these compounds generate reactive oxygen species (ROS), such as HO- or O2-, which can react with nucleic acids found in DNA and RNA. In …


Risk Factors And Trends In Antimicrobial Susceptibility Patterns In Strains Of Neisseria Gonorrhoeae Following Changes In The Cdc Sexually Transmitted Disease (Std) Treatment Guidelines – United States, 2012-2018, Niketta A. Womack Jan 2021

Risk Factors And Trends In Antimicrobial Susceptibility Patterns In Strains Of Neisseria Gonorrhoeae Following Changes In The Cdc Sexually Transmitted Disease (Std) Treatment Guidelines – United States, 2012-2018, Niketta A. Womack

College of Graduate Studies: Theses & Dissertations

Antimicrobial resistant Neisseria gonorrhoeae (N. gonorrhoeae) has become a major global public health concern in the 21st century. Surveillance activities are essential in identifying risk factors in priority populations. The purpose of this study was to identify risk factors associated with and trends in antimicrobial susceptibility patterns in N. gonorrhoeae strains identified through the Gonococcal Isolate Surveillance Project (GISP). A study sample of 37,157 men was evaluated to measure adherence to changes in CDC’s STD treatment guidelines in 2012 and 2015. Data were analyzed to measure associations between independent and dependent variables by conducting bivariate and logistic regression …
