Exploration Of Stable Isotope Analysis To Identify Prior Host In Ixodes Scapularis, Imogene Welles
Exploration Of Stable Isotope Analysis To Identify Prior Host In Ixodes Scapularis, Imogene Welles
Honors Theses
One of the most enigmatic concepts in tick-borne disease ecology is how to identify the prior host of a questing tick. The ability to do so would provide predictions to directly aid in controlling the spread of the many tick-borne pathogens, including the bacterial spirochete Borrelia burgdorferi, which causes Lyme disease in humans. I explored the application of a novel technique, stable isotope analysis (SIA), to identify the most recent host in molted Ixodes scapularis (black-legged tick). The common reservoir and feeding host, Peromyscus leucopus (white-footed mice; n = 46), were trapped, infested with nymphal ticks, and fed restricted …
The Effects Of Alpha-Tocopherol And Ascorbic Acid On Metastatic Breast Cancer Cells, Scout Treadwell
The Effects Of Alpha-Tocopherol And Ascorbic Acid On Metastatic Breast Cancer Cells, Scout Treadwell
Honors Theses
Breast cancer is a multifaceted, complex disease that affects hundreds of thousands of patients every year. Although there has a been a decline in the mortality rate of this disease, it is still vital to investigate and discover new possible treatments. One area of research involves the generation of reactive oxygen species (ROS) in cancer cells and the possibility of ROS-induced apoptosis. Antioxidants such as Vitamin C and Vitamin E have been shown to serve as pro-oxidants. Instead of detoxifying the cell from damaging ROS, these compounds can stimulate ROS production, triggering an apoptotic cascade in the cell. In this …
Baseline Health Assessment Of A Rural Delta Community, Sydney Mitchell
Baseline Health Assessment Of A Rural Delta Community, Sydney Mitchell
Honors Theses
The Lower Mississippi Delta is characterized by poverty, chronic health issues, health disparities, and food insecurity. The rural Delta communities are primarily African American, experiencing disproportionately higher rates of poverty, job loss, and chronic health problems. Historically, chronic health issues have persisted in these areas over time, including obesity, hypertension, and diabetes, which have only seemed to increase in this region. The food environment in this rural region tends to assist in the creation of the largely obesogenic population which, in turn, contributes to the increased prevalence of diabetes and hypertension and a lower quality of life. Many residents in …
Characterization Of A Plasmid-Based Dna Vaccine For Simian Immunodeficiency Virus, Priya Sanipara
Characterization Of A Plasmid-Based Dna Vaccine For Simian Immunodeficiency Virus, Priya Sanipara
Honors Theses
Described as one of the world’s worst pandemics, HIV (Human Immunodeficiency Virus) infects millions of people each year and is the cause for AIDS (Acquired Immunodeficiency Syndrome). Despite the development of vaccines for numerous infectious diseases such as polio, small pox, and influenza, a vaccine for HIV remains elusive due to the virus’s high mutation rate and ability to evade the immune system. HIV causes depletion of CD4+ lymphocytes, resulting in a weakened immune system. However, the development of a plasmid-based DNA vaccine approach may help revolutionize vaccine development for HIV due to its ability to confer cellular and humoral …
How Misinformation And Mistrust Compound The Threat Of Epidemics, William Boyd
How Misinformation And Mistrust Compound The Threat Of Epidemics, William Boyd
Honors Theses
This thesis was conducted to study the effects of misinformation and medical mistrust on the public health field. I use the events of the Chapare Virus outbreak in Bolivia in the summer of 2019 and the public dialogue during that time period to discuss these themes. I used data from market survey's in La Paz, newspaper articles from Página Siete, and Tweets from the time period of the outbreak. My findings suggest that misinformation and medical mistrust affected public health measures, which has major implications for the way the public health field should address future public health events.
“A Moral Imperative To Prevent Aids”: Race And Religion In Atlanta’S Aids Activism, 1981-1993, Madison Bailey
“A Moral Imperative To Prevent Aids”: Race And Religion In Atlanta’S Aids Activism, 1981-1993, Madison Bailey
Honors Theses
The early years of the AIDS epidemic marked a tumultuous period of American history, calling into question the authority of doctors and the ability of scientists to cure disease. Already marginalized groups, such as gay men and intravenous drug users, appeared to be most vulnerable to a deadly virus with no cure or effective treatments. In the face of discrimination, activists rose up to provide necessary services for AIDS patients and advocate on their behalf. This activism uniquely characterized the early AIDS epidemic and permanently changed the field of biomedical research. The current historiography of AIDS activism tends to focus …
Bacterial Load In Virtual Reality Headsets, Benjamin Creel
Bacterial Load In Virtual Reality Headsets, Benjamin Creel
Honors Theses
Virtual reality technology is a rapidly growing field of computer science. Virtual reality utilizes headsets which cover the user’s eyes, nose, and forehead. In this study, I analyzed the potential for these headsets to become contaminated with bacteria. The nosepieces and foreheads of two HTC Vive VR headsets of the Department of Computer Science of the University of Mississippi were sampled over the course of a seven-week Immersive Media (CSCI 447) course. Serial dilutions were performed, and samples were plated on various culture media. Following incubation, counts of bacteria were determined. DNA was extracted from bacterial growth on plates from …
Investigating The Role Of Rap1a In Medial Arterial Vascular Calcification, Amelia Grace Haydel
Investigating The Role Of Rap1a In Medial Arterial Vascular Calcification, Amelia Grace Haydel
Honors Theses
Cardiovascular disease is the leading cause of death in the United States with one of the major contributors being vascular calcification, characterized by the deposition of calcium-phosphate hydroxyapatite. Once thought to be a passive process due to aging, medial vascular calcification is becoming better understood as a tightly regulated, cellmediated process. Vascular smooth muscle cells (VSMCs) within the medial arterial layer respond to inflammation, oxidative stress, and changes in pyrophosphate levels, which induce differentiation into osteoblast-like cells. Fibroblasts within the adventitial layer (AFBs) also alter their function in response to vascular calcification signaling, although this is largely understudied. The AGE/RAGE …
