Health Of Value Menu: Cost Versus Benefits Analysis, Lucas Sartain

Undergraduate Research Conference

Consumption of fast food is rapidly increasing on both a domestic and global scale. Fast food has become increasingly popular not only for its quick service, but also for the economic savings it provides. One arguable factor however, rests with the health concerns that accompany this category of food. Important preliminary measures include clearly defining what is classified as fast food, what is considered to be unhealthy, and what determines healthiness. The most frequently ordered items at most fast food restaurants are located on the dollar menu. Through various research, it will be determined whether the dollar menu is less …

Removable Discontinuity: Crispr, Gene Drives, And Bioethics, Emily Dunnahoe

Undergraduate Research Conference

This paper questions whether bioethical scrutiny has been devoted to the ethical dilemmas that have arisen with advancements of CRISPR-Cas 9 gene editing techniques, particularly its use in conjunction with gene drive applications. Therefore, the trend of genetic research using both gene drives and CRISPR-Cas 9 systems must be established, while also simultaneously observing the trend of bioethical scholarly works. The tabulation of all articles from 2012 to 2015 from selected genetic journals yielded a significant increase in articles relating to CRISPR, while no articles were found in their selected bioethical counterparts for the same period. Similarly, no significant CRISPR/gene …

Witcher, Rebekah Napier-Jameson, Hannah N. Lockwood, Josephine Taylor, Beatrice A. Clack, Judith M. Ball, Fabricio Medina Bolivar, Rebecca D. Parr

Undergraduate Research Conference

Rotavirus (RV) infections are a leading cause of severe gastroenteritis in infants and children under the age of five. There are two vaccines available in the United States and one in India that can be administered early in childhood, however they only protect against specific strains1. From our previous work, both arachidin-1 (A1) and arachidin-3 (A3) from peanut (Arachis hypogaea) hairy root cultures significantly inhibit simian RV replication2,3,4. The purpose of this study was to determine if a human intestinal cell line, HT29.f8, infected with a human RV, Wa, was affected by A1 and A3. Cell viability assays were utilized …

Antimicrobial Properties Of S-Benzofuran-2-Yl Ethanol Produced By Biotransformation, Nick Cheatwood, Ann Davis, Elizabeth Schabeck, Kelsi Hooker, Michele Harris

Undergraduate Research Conference

All living organisms contain enzymes to carry out biological reactions, which produce substances with a specific three dimensional shape. Enantiomers are two molecules that are mirror images of each other just as hands are mirror images of each other. It is well known in the pharmaceutical world that one of the enantiomers (one of the mirrorimage molecules) has a positive biological effect while the other can be harmful or have no effect. Currently, any potential pharmaceutical that could exist as enantiomers must have each enantiomer tested for biological activity prior to FDA approval. In our laboratory, we have focused on …

The Methods Used For Eradication Of Polio Versus The Defense Efforts That Are Being Conducted For Global Defense Against Ebola, Kalyn Johnson

Undergraduate Research Conference

Poliovirus eradication has been a long-lasting and difficult process that has become a global issue. The World Health Organization and the European Union have been trying to end the terrible reign of this abhorrent disease since the 1980s and are continually fighting the virus today. Poliomyelitis is an Old World disease, much like smallpox. It has been easily, through a twenty year process, eradicable through mass vaccination and circle vaccination.

However, as poliovirus is coming to the end of its reign, a more recent danger lurks nearby. Ebola virus is considered a non-traditional disease in that it requires more developed …

Using Freshwater Mussels As An Indicator For River Water Quality, Joseph Gerland, Will Titone, Ariana Clark, Brad Michael

Undergraduate Research Conference

Using the freshwater mussel to monitor water quality is a practical and advantageous way to use nature’s indicator species. River water quality is an important measurement that is constantly monitored for many purposes. The sampling involved with monitoring can be very costly and time-consuming. Using mussels as indicator species could save money and time. So, this project has been dedicated to exploring the applications and reality of using freshwater mussels to monitor river quality.

Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal

Georgia College Student Research Events

The United States spends $20 billion each year on farm subsidies. Farmers face increased risk and income variation when their crop portfolio is less diversified. It’s possible for farm subsidies to decrease diversification if they are focused on specific crops. Utilizing state level subsidy and agricultural data from the Environmental Working Group, I used econometric analysis to estimate the effect of farm subsidies on crop diversification. I used the number of acres planted from the 15 top most subsidized and grown crops in the United States to derive my dependent variable, the Herfindahl-Hirschman index (HHI). The HHI is a market …

Disease Introduction By Aboriginal Humans In North America And The Pleistocene Extinction, Zachary D. Nickell, Matthew D. Moran

Journal of Ecological Anthropology

While overhunting and climate change have been the major hypotheses to explain the late-Pleistocene New World megafaunal extinctions, the role of introduced disease has only received brief attention. Here, we review pre-Columbian diseases endemic to aboriginal Americans and evaluate their potential to cause large-scale mortality in Pleistocene mammals. Of the probable communicable diseases present in pre-Columbian times, we regard anthrax and tuberculosis as viable candidates. These two diseases demonstrate characteristics that could have made them deadly to immunologically naïve populations. Introduced disease, as a primary cause or interacting with overhunting and climate change, could have contributed to the decline and …

Dna-Binding And Cellular Uptake Properties Of Pyrrole-Imidazole Polyamides, Maria J. Scuderi

Dissertations

Pyrrole-imidazole polyamides (PAs) represent a class of synthetic ligands that bind to the minor groove of DNA through hydrogen bonds and can be programmed to recognize predetermined DNA sequences. Potential applications of these compounds include gene expression modulation, antimicrobial activity and cell imaging.

Studies conducted in our lab in collaboration with NanoVir have shown that large PAs exhibit antiviral activity against Human Papillomavirus (HPV), which is the most common sexually transmitted infectious agent in the US and the primary factor for the development of cervical cancer. PAs act against HPV by targeting the viral DNA and promoting its selective elimination …

Dynamic Patterns Of Expression For Genes Regulating Cytokinin Metabolism And Signaling During Rice Inflorescence Development, Maria V. Yamburenko, Joseph J. Kieber, G. Eric Schaller

Dartmouth Scholarship

Inflorescence development in cereals, including such important crops as rice, maize, and wheat, directly affects grain number and size and is a key determinant of yield. Cytokinin regulates meristem size and activity and, as a result, has profound effects on inflorescence development and architecture. To clarify the role of cytokinin action in inflorescence development, we used the NanoString nCounter system to analyze gene expression in the early stages of rice panicle development, focusing on 67 genes involved in cytokinin biosynthesis, degradation, and signaling. Results point toward key members of these gene families involved in panicle development and indicate that the …

Nutrition And Exercise Plan For College Students, Rachel Walny

Honors Projects

This is a website designed to help college students lead a healthy and active lifestyle. Many students are unaware of the exercise and nutrition recommendations for adults and have not been in the practice of living on their own and cooking their own meals. It can also be difficult for college students to find time to exercise and eat healthy due to their busy schedules. This source is meant to take some of the planning and questioning out of the process and provide students with a resource that can guide them them in reaching their exercise and nutritional goals.

Identification Of Novel Interactors Of Sec6 Via Genetic Suppressor Screen Using A Saccharomyces Cerevisiae Genomic Dna Library, Y. Ellen France Phd, Emily Parrish, Raira Ank, Tristan Peterman, Sarah Mork, Billie Mills, Lindsey Duke, Jyoti Lama

Georgia College Student Research Events

Polarized protein secretion is a fundamental process for all organisms, from yeast to higher eukaryotes. The secretory pathway in eukaryotes includes many steps mediated by hundreds of essential proteins. Our interest lies on Sec6, which is an 88kDa protein subunit of the tethering complex named exocyst, which is known to play diverse roles in recognition, tethering, and SNARE-mediated fusion of secretory vesicles. Previous work on Sec6 done by Munson and Songer (2009) explored phenotypes of two novel SEC6 mutant proteins, whose conserved surface amino acids had been altered. Both sec6-49 and sec6-54 mutant alleles displayed severe temperature sensitive growth and …

Determination Of The Binding Site Of Adenovirus E4 11k On The Cellular Protein Ddx6, Clint E. Edmunds, Courtney F. Moon

Georgia College Student Research Events

Adenovirus is a double-stranded DNA virus that is responsible for localized infections, such as upper respiratory tract infections. The virus takes over the target cell through many mechanisms, in particular taking control of host cell gene expression mechanisms as well as controlling host cell protein synthesis machinery. One of the functions of the adenovirus E4 11k protein is in turning off host cell protein synthesis and regulating late viral gene expression. E4 11k from all adenovirus subclasses has been shown to disrupt cellular RNA processing bodies (P-bodies), and adenovirus serotype 5 has a direct interaction with a P-body protein, Ddx6. …

Impact Of Cations On The Sorption Capabilities Of Kaolin Towards Biofilm-Forming Bacteria, Rachel E. Brineman

Georgia College Student Research Events

Biofilm-forming bacteria cause problems for industries such as medical, food, and water treatment. Due to its heterogeneous charges, kaolin is capable of sorption of these microorganisms. These charges are impacted by pH and cations, which change the electrostatic interactions between kaolin particles and microorganisms. Proper pH and cation composition may lead to enhanced sorption. The impact of Al3+ cations on kaolin sorption of Gram negative (E. coli and P. aeruginosa) and Gram positive (B. megaterium and S. aureus) was investigated. Calcined kaolin and Diatomaceous Earth kaolin, which were selected in previous studies, were incubated in triplicates with the above organisms …

Examining The Experiences Of Athletic Trainers As They Transition Into Their First Full-Time Position, Stephanie M. Mazerolle, Mclain Whitney, Christy Eason

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Transition to clinical practice is an important topic in athletic training, as it can be a period of time that presents challenges for the athletic trainer. Most of the research pertaining to transition to practice focuses on the skills and knowledge necessary for clinical practice, yet we know that stress can manifest from not only being an independent practitioner but also from learning how to balance one’s roles. We wanted to understand the perspective of today’s novice athletic trainers and how they feel in their first full-time position, specifically relating to their professional development and establishment or maintenance of work-life …

Functional Neural Connectivity Associated With Moral Processing In Healthy And Antisocial Samples, Samantha Jean Fede

Psychology ETDs

Although research finds that brain abnormalities during moral decisions underlie traits that lead to crime, understanding of these neural dynamics is limited. Here we use two samples to explore the role network engagement and components during moral processing. We used independent component analysis and functional network connectivity analysis to examine hemodynamic response during an fMRI task of moral processing. Eighty-four community and 539 incarcerated adult men and women participated; MANCOVA and machine learning algorithms were used to identify individual and group differences in both samples. We found patterns of neural engagement and connectivity consistent with proposed models of moral cognition …

Gregariousness Does Not Vary With Geography, Developmental Stage, Or Group Relatedness In Feeding Redheaded Pine Sawfly Larvae, John W. Terbot Ii, Ryan L. Gaynor, Catherine R. Linnen

Biology Faculty Publications

Aggregations are widespread across the animal kingdom, yet the underlying proximate and ultimate causes are still largely unknown. An ideal system to investigate this simple, social behavior is the pine sawfly genus Neodiprion, which is experimentally tractable and exhibits interspecific variation in larval gregariousness. To assess intraspecific variation in this trait, we characterized aggregative tendency within a single widespread species, the redheaded pine sawfly (N. lecontei). To do so, we developed a quantitative assay in which we measured interindividual distances over a 90-min video. This assay revealed minimal behavioral differences: (1) between early-feeding and late-feeding larval instars, …

Relationship Between Structure And Functional Connectivity Within The Default Mode Network, Andrei A. Vakhtin

Psychology ETDs

We proposed a novel measure of conceptualizing dynamic functional network connectivity (FNC) in the human brain using flexibility of functional connectivity (fFC), which captures the variance of functional connectivity across time. In task-free fMRI scans (N = 122), this measure was demonstrated to correspond to the underlying structural connectivity (SC) within the default mode network (DMN), while static functional connectivity (sFC) did so to a relatively low degree. As SC likely does not develop to facilitate task-free brain function, but rather to integrate information during cognitive engagement, we argue that fFC can estimate the potential functional connectivity exhibited outside of …

Phantom Limb Pain: It’S Not ‘All In My Mind, It’S In My Neurons!', Meredith Conroy (Class Of 2017)

Biology Undergraduate Publications

Phantom limb pain (PLP) is a burning, stabbing, shooting, aching, and/or throbbing pain that an amputee feels in his or her amputated limb. According to recent statistics, PLP affects 50-80% of amputees—over one million amputees in the United States alone. With this condition being so widespread and detrimental to patients’ day to day life it is important to understand its mechanisms. However, there is a great deal of debate as to whether PLP is neurological or psychological.

The Effects Of Dietary Intake On Fuel Metabolism During Aerobic Capacity Exercise, Taylor Lynn Stephenson

Theses and Dissertations

In order to produce mechanical energy through muscular activity, the body must oxidize chemical energy, carbohydrate, fat, or protein through metabolic processes, which then results in the production of ATP as mechanical energy through exercise. Total body metabolism, specifically skeletal muscle depends on factors such as the intensity and duration of exercise, substrate availability, and Training status. During exercise at low intensities (25% of VO2 max) fat is the primary macronutrient that is oxidized for energy. As the exercise intensity progresses, (65% of VO2 max) there is an alteration in skeletal muscle utilization, which results in mainly the use of …

Reduction In Activity By Noxious Chemical Stimulation Is Ameliorated By Immersion In Analgesic Drugs In Zebrafish, Javier Lopez-Luna, Qussay Al-Jubouri, Waleed Al-Nuaimy, Lynne U. Sneddon

Anesthesia and Analgesia Collection

Research has recently demonstrated that larval zebrafish show similar molecular responses to nociception to those of adults. Our study explored whether unprotected larval zebrafish exhibited altered behaviour after exposure to noxious chemicals and screened a range of analgesic drugs to determine their efficacy to reduce these responses. This approach aimed to validate larval zebrafish as a reliable replacement for adults as well as providing a high-throughput means of analysing behavioural responses. Zebrafish at 5 days postfertilization were exposed to known noxious stimuli: acetic acid (0.01%, 0.1% and 0.25%) and citric acid (0.1%, 1% and 5%). The behavioural response of each …
