Haloferax Volcanii For Carotenoid Production, Erika Smith

Honors Theses

Carotenoids are used as natural colorants and have been shown to have numerous health benefits, making these molecules highly desirable in the aquaculture, pharmaceutical, and nutraceutical markets. There is increasing consumer demand for the natural synthesis of carotenoids, but current methods are limited by the cost and difficulty of extraction from organisms. The halophilic archaeon Haloferax volcanii is amenable to extraction and has an endogenous carotenoid biosynthetic pathway that culminates in the accumulation of the carotenoid bacterioruberin; however, H. volcanii also synthesizes important precursors that can be converted into more highly-desired carotenoids, such as β-carotene and astaxanthin, in the presence …

The Identification And Application Of Generalizable Spatial Patterns Of Human-Wildlife Conflict, Vivian F. Hawkinson

Honors Theses

Many human-wildlife conflict studies focus on one location or one individual species or taxonomic group; fewer comparative studies analyze patterns of conflict across species and regions. As a result, numerous studies report similar conclusions across diverse cases of human-wildlife conflict. I found 133 scholarly articles published between 1975 and 2017 referencing distance from a protected area boundary as a variable associated with human-wildlife conflict. I identified three generalizable patterns of human-wildlife conflict that appear across taxonomic groups and geographic locations. The family Felidae had the highest maximum average conflict distance and furthest distance from a protected area that conflict was …

The Effects Of Nutrient Limitation On Toxin Production For The Harmful Algal Bloom Species, Pseudo-Nitzschia, In The Gulf Of Maine, Julia M. Park

Honors Theses

Pseudo-nitzschia is a pennate marine diatom that produces the neurotoxin domoic acid (DA). Domoic acid accumulates in the digestive tract of filter feeders and becomes concentrated at higher trophic levels. When DA concentrations reach critical levels, consumption of toxic shellfish can induce a condition known as Amnesic Shellfish Poisoning (ASP), which has been responsible for the deaths of marine mammals, seabirds and humans. This study worked to respond to a toxic Pseudo-nitzschia bloom in the Gulf of Maine during the fall of 2016, with the goal of quantifying and identifying Pseudo-nitzschia spp. in the bloom region and to determine the …

Role Of Nest Site Microclimate And Food Availability In Chick Development And Reproductive Success In Black-Legged Kittiwakes (Rissa Tridactyla), Lindsay Mae Lacey

Honors Theses

Seabirds are marine top predators, and as such are often studied as bioindicators of climate shifts (Oswald and Arnold 2012). Though many studies have analyzed the effect of macroclimatic variation on marine prey species availability and thus seabirds, few have analyzed effects of microclimate - fine spatial patterns of climate (Mantua and Hare 2002; Hatch 2013; Kim and Monaghan 2005a). I tested the hypothesis that localized temperature and humidity at nest sites interact with food availability to alter black-legged kittiwake (Rissa tridactyla) nest site quality, chick body condition during growth and development, and reproductive parameters including Julian lay …

Stress In College Students: Associations With Anxiety And Perfectionism, Emory Hamblin

Honors Theses

Psychosocial stressors are prevalent in the workplace and academic environment largely due to emotional responses from rising conflict, unattainable demands, or a decreased sense of control. An individual's perception of stress is interrelated to the characteristic of perfectionism and the level of anxiety one possesses. Stress is commonly associated with adverse circumstances, and perfectionism is characterized by the setting of unrealistically high standards accompanied by a personal and social standard, attitude, or philosophy. Anxiety is characterized by increased physiological arousal, inhibition of ongoing activities, and a change in individual priorities. Previous studies have examined anxiety's relation to stress-invoking stimuli, but …

Targeting Metastatic Breast Cancer With Statin Drugs And Coq10, Jacob Thrasher

Honors Theses

Statin drugs are commonly prescribed to lower cholesterol levels in patients, but recently statins have been under investigation as a potential anti-cancer drug. Statins are HMG-CoA reductase inhibitors and subsequently inhibit the mevalonate pathway and cholesterol synthesis. Since cholesterol trafficking is vital in the growth and metastasis of cancer, statin drugs are being studied to explore their effects on cancer cells. CoQ10, one of the products from the mevalonate pathway, also has shown some potential anti-cancer properties, but its use to combat cancer is controversial. While some studies have shown that CoQ10 supplements can be synergistic with other cancer treatment …

Abortion Access And Child Maltreatment: A Cross-National Analysis, Alexandra Gersdorf

Honors Theses

This thesis has examined the impact of restricted abortion access on different indicators of child maltreatment. Drawing from literature linking unwanted pregnancies to child maltreatment, I posited that given the proposed relationship between unintended pregnancies and child maltreatment, we should expect to see increased instances of maltreatment within countries that allow less of forbid women from accessing abortions. For this purpose, I created an index of abortion access to numerically rate a country's level of liberality or restrictiveness. Then, using data from 49 countries, this thesis examined the potential linkage across a variety of measures that indicate child maltreatment while …

Cm-Dii And Mcf-7 Breast Cancer Cell Responses To Chemotherapeutic Agents, Ashten M.C. Anderson

Honors Theses

CM-DiI is a lipophilic, red fluorescent dye used for staining and tracking the migration of cells. CM-DiI makes it possible to visualize cells in histological regions and can therefore be very useful for the tracking of cancer cell proliferation and metastasis in vivo. The ability to track and quantitate cancer cell proliferation in vivo is essential for cancer drug discovery. If CM-DiI labeled cancer cells respond to chemotherapy agents similar to unlabeled cancer cells, it facilitates screening of potential anti-cancer compounds using CM-DiI labeled cells in a xenotransplanted, transgenic zebrafish model (Danio rerio). To investigate whether CM-DiI labeling would affect …

In the past thirty years, Chile has experienced dramatic political, social, economic, and cultural changes. A constant source of national identity, pride, and comfort through this tumultuous period was (and continues to be) fútbol. Chileans follow the sport relentlessly and it is a key part in the construction of local, regional, and national identities. My thesis work aims to answer the following question: how do the relationships between consumption cultures and football create/delineate/eliminate space for women in the overarching social public sphere of national belonging? In order to answer this question, I utilize a mixed methods approach to investigate how …

Attitudinal Changes In Experiential Learning Via Poverty Simulation, Madison E. Bandler

Honors Theses

More than 10% of people living in the United States are impoverished. These human beings are subjected to poor living conditions, experience increased mental and emotional stress, lack basic necessities, and are more susceptible to many health conditions. Lack of poverty awareness and understanding has contributed to the spread of misconceptions, the majority of which are damaging to the impoverished community. These misconceptions affect how impoverished individuals are viewed by health care professionals and influence the quality of medical treatment they receive. The Missouri Community Action Poverty Simulation (CAPS) is an experiential learning tool that requires participants role-play a low-income …

Cardiolipin Profiling In Metastatic Breast Cancer Cells, Meghan Houston Mcneely

Honors Theses

Six human breast cancer cell lines (MDA-MB-231, LM, BoM, T47D, MCF7, and MCF7-BoM) were treated with three differentially targeted phospholipase inhibitors (bromoenol lactone, tricyclodecan-9-yl-xanthogenate, and halopemide) as well as various dietary oils (canola oil, avocado oil, coconut oil, olive oil, sesame oil, and soybean oil). Cell viability assays were performed to examine the effects of each inhibitor and oil in varying concentrations on the proliferation of each breast cancer cell line. The goal was to detect changes in cardiolipin concentration within each cell line after exposure to a series of various phospholipase inhibitors and oils. Liquid chromatography-mass spectrometry (LC-MS) was …

Effects Of Emotion And Construal Level On Obesity Stigma, Peyton D. Curtis

Honors Theses

We conducted the present study to determine how emotion and construal level contribute to obesity bias. Specifically, we examined if different emotions, such as disgust, sadness, and happiness, played a role in several different judgments of an obese versus thin individual: 1) general impressions, 2) supporting a friend, and 3) endorsing personal versus biological/environmental causes for weight. We also investigated whether a self me construal or collective we construal influenced these judgments. We additionally considered whether emotion and these construal levels would interact to influence such judgments. The current work found that emotion and construal level did not interact to …

Development Of A Novel Salivary Cortisol Laboratory Experiment For Undergraduate Physiology Students, Charmin C. Guy

Honors Theses

Developing an endocrine-based laboratory exercise for undergraduate students is challenging because of the limitations that are characteristic of endocrine processes. These laboratory exercises often involve invasive methods and expensive biochemical analysis. They are also time consuming because of the slow-acting endocrine responses. A potential endocrine-based exercise that can be completed in 2-3 hours, is non-invasive, and at a low cost is a salivary assay. This assay is not without drawbacks, however, including sample collection outside the laboratory classroom. Cortisol is a hormone that is accessible in saliva and provides some insight into the Hypothalamic-Pituitary-Adrenal Axis (HPA Axis), also known as …

Effects Of Predation On The Biochemical Constituents Of The Bleached Soft Coral Sinularia Polydactyla, Carley Elizabeth Cole

Honors Theses

Climate change can indirectly affect the level of predation on soft corals. As sea temperatures rise, more and more bleaching events are occurring, which can affect the production of chemical defenses and the concentrations of the biochemical constituents that make up the soft corals. These changes may make the soft corals more attractive to predators. This phenomenon is suggested by the environmental stress theory (EST), which states that under stressful conditions, more of an organism's energy is allocated to survival rather than to other factors, such as reproduction or predator deterrence. To test the effect of predation on already bleached …

The study also synthesized written immigration policy and incorporated visa data from approved visa applications from the years …

Effects Of Housing Management On Vaccination Success Against Eimeria Infection In Chickens, Louis Wilson Benton

Honors Theses

Coccidiosis is a disease of the gastrointestinal system of commercially raised chickens (Gallus gallus). The infection is caused by multiple parasitic species of the coccidian genus Eimeria. Eimeria proliferate within large poultry houses leading to decreased nutrient absorption, anorexia, and death of the host. Scheduled vaccination with live coccidian oocysts should minimize production losses, but various management factors may contribute to variation in the outcome. I investigated whether by tracking infection cycles in detail it might be possible to improve poultry production. Feces were collected daily from four farms across a two-month period to understand how peaks in oocyst shedding …

Healthcare Certificates Of Need In Mississippi: Policy Review And Recommendation, Seth Dickinson

Honors Theses

Healthcare Certificates of Need, often abbreviated as CON, are public policies implemented across America with many intentions but the primary purpose of engaging the healthcare marketplace in a way that allows for government regulation and monitoring. Over time, states have created their own types of certificate of need policies while others have abandoned these types of policies all together. Mississippi is a member of the former group that has crafted its own type of policies geared towards enabling Certificates of Need. As the healthcare marketplace shifts across America, this research delves into the certificate of need policies of states with …

Effects Of Point Of Purchase Marketing On Selection Of Vegetables In A University Greek House Foodservice, Shelton Wittenberg

Honors Theses

Weight gain is common for undergraduate college students because of factors such as body maturation, increased consumption of fast food, and less physical activity. Weight gain may continue after college if diet and exercise habits do not improve, so learning healthy habits during college can contribute to a healthy adulthood. Recent research has reported that weight gain is inversely related to fruit and vegetable consumption. Because a large portion of college students' diets come from on-campus dining options, fruit and vegetable intake may be lacking because many of these venues may not serve these items or serve them in a …
