  • Effects of Withholding Cell Phones on Students' Autonomic Arousal, State Anxiety, and Test Scores

    Recinos, Manderley; Streets, Hannah; Gaffney, Jasmine; Department of Psychological Sciences; Johnson, Michelle; Augusta University (2019-02-13)
    Approximately 85% of Americans aged 18-29 have smartphones. Many people report that they get agitated when their phones are not immediately accessible.1,2Researchers studying the links between phone use and academic performance have focused on their disruptive nature (e.g., texting). No research has examined the effects of withholding phones during testing on test performance. The objective of this study was to assess whether withholding phones during testing affected students state anxiety, skin conductance (SC), and test scores. State anxiety is situationally determined, transitory, and associated with autonomic nervous system activation. SC (sweat gland secretions) is an index of sympathetic nervous system activation. We expected higher levels of self-reported state anxiety, higher levels of SC, and lower test performance among students who had their phones withheld compared with students who kept their phones. Eighty-six students participated. There were three conditions: phones withheld but kept in the same room as testing condition (n= 31), phones withheld but sequestered in a different room (n= 28), and control where students were not separated from their phones (n= 27). One-way MANOVA revealed no differences between the groups in state anxiety, SC or test scores. Data did reveal interesting trends we would like to discuss.
  • IS EXERCISE THE BIGGEST INFLUENCER OF HAPPINESS? RESEARCHING HOW INFLUENTIAL EXERCISE IS IN COMPARISON TO OTHER VARIABLES IN DAILY LIFE

    Collins, Megan; Department of Sociology, Criminal Justice & Social Work; Davies, Kim; Augusta University (2019-02-13)
    There have been multiple studies that indicate that there is a relationship between exercise and happiness. In this research, I test whether exercise is the strongest factor when compared to other common variables in a person's life for predicting happiness. Using the 2012 General Social Survey (GSS) data, I test several different variables in order to determine which of them has the strongest correlation with a person's general happiness. The 2012 GSS consisted of 4,820 respondents that ranged in age from 18 to 89. Using logistic regression, I compare the variables of sex, marriage, age, frequency of exercise, employment, and income and found that exercise has a positive relationship with a person's general happiness and that is the most strongly correlated variable. Other variables were also found to be significant and will be discussed in the poster.
  • PROFILING G PROTEINS USING BIOLUMINESCENCE RESONANCE ENERGY TRANSFER

    Farooq, Maheen; Department of Chemistry and Physics; Department of Pharmacology & Toxicology; Spencer, Angela; Lambert, Nevin; Okashah, Najeah; Augusta University (2019-02-13)
    GPCRs are receptors that act in signal transduction pathways via guanosine nucleotide-binding proteins (G proteins). Extracellular ligands act on GPCRs resulting in activation of one or more G protein subtypes (Gs, Gi/o, Gq/11 and G12/13) affecting the concentration of intracellular second messenger molecules ultimately altering cellular function. Cellular responses to external signals are typically studied indirectly by measuring concentration changes in second messengers. However, this approach can be problematic as many GPCRs can activate multiple G protein subtypes, and many second messenger pathways engage in crosstalk. To address this issue, we used Bioluminescence Resonance Energy Transfer (BRET) to directly measure coupling between 5-hydroxytryptamine (5-HT; serotonin) receptors and different G protein family subtypes. We co-transfected cells with plasmid DNA encoding the 5-HT2B or 5-HT4 receptors fused to the bioluminescent protein nanoluciferase (NLuc) as well as plasmid DNA containing G protein subtypes fused to the fluorescent protein Venus. In BRET assays, we found that mGsq couples to 5-HT2B and mGscouples with 5-HT4 in response to 5-HT activation. These results are consistent with the literature. Interestingly, initial studies suggest that activated 5-HT4 shows secondary coupling to mGsi highlighting the potential novel signaling pathways that can be elucidated using this technique.

    Sura, Survasha; Department of Biological Sciences; Department of Biochemical and Molecular Biology; Georgia Cancer Center; Rajpurohit, Surendra K; Augusta University (2019-02-13)
    Zebrafish have emerged as a powerful model organism for elucidating the development and function of microglia. Generation of new transgenic reporter lines and imaging tools strengthen the zebrafish model in microglia study�in-vivo. The aim is to develop a novel compound transgenic line to study the inflammatory process mediated by NF-kB in microglia cells. This novel compound transgenic line will establish a new model for microglia study. To generate the novel compound zebrafish transgenic model for microglia, we are crossbreeding microglia transgenic line zebrafish (Tg(mpeg1:mCherry) with the NF-kB Tg(6xNFkB:EGFP) transgenic progeny. We first generate a heterozygous F1 progeny which will be bred to generate an F2 homozygous progeny. Once the F1 progeny of the Microglia-NfkB transgenic line is developed, they will be crossbred to develop the Homozygous compound transgenic line. Fluorescent Microscopy will be used to screen the larvae generated from the breeding events. By developing the compound transgenic line, we are optimizing microglia isolation and sorting methodology by using the related antibodies as the marker. The NF-kB microglia transgenic line will provide a unique platform for drug screening to address microglial based ailments, thus furthering the understanding and treatment of human disease.
  • EXAMINING THE EFFECTS OF AETOKTHONOS HYDRILLICOLA EXTRACT ON OXIDATIVE STRESS IN C6 CELLS

    Ward, Kayla; Department of Biological Sciences; Wiley, Faith; Augusta University (2019-02-13)
    Aetokthonos hydrillicola, a species of cyanobacteria, has colonized an invasive species of hydrilla in the lakes of the Southeastern United States. This cyanobacterium is suspected to cause Avian Vacuolar Myclinopathy (AVM). AVM is a neurological disease that affect birds. Bald eagles and American coots have been primarily studied and known to be affected by AVM. Symptoms of AVM consist of brain lesions, loss of basic motor skills, and the disease often leads to death. Extracts of A. hydrillicola are toxic to C6 cells, and this cell line is used as a model to examine the mechanism of toxicity. The aim of this research project is to understand the role of oxidative stress in A. hydrillicola cytotoxicity and determine if antioxidant compounds may protect the cells. Common oxidative stress inhibitors, Gingko biloba extract and selenium, have been tested in different concentrations in order to determine if oxidative stress is present and preventable. These compounds did not prevent toxicity in the C6 cells exposed to the cyanobacterial extracts. The presence of oxidative is currently being further investigated using a 2-7 dichlorofluorescin diacetate (DCFH-DA) assay, which indicates the presence of reactive oxygen species.

    Boomer, Houlton; Department of History, Anthropology & Philosophy; Bratton, Angela; Augusta University (2019-02-13)
    This research focuses on how the health care system one is used to using effects ones ability to seek and receive care in another System. Specific examples used within the study are the Western Medical System, The Traditional Chinese Medical System, and African American Root medicine. The study was done with interviews to health care providers and with surveys to citizens of the Augusta area. Unfortunately the data collected proved inconclusive with regards to the research question. However it did reveal a great deal of information about the patient population in the area, namely the tendency to remain with a single system with regards to health and the role of financial constraints in choice of healthcare system.
  • AN EXAMINATION OF MORAL PANICS: HOW THE FEAR OF SATANISM AFFECTED TABLETOP ROLE PLAYING

    Williams, Travis; Department of Biological Sciences; Department of Communication; Department of Anthropology & Philosophy; Johnson, Edgar; McClelland-Nugent, Ruth; Augusta University (2019-02-13)
    Moral panics around youth entertainment have been an occurrence as long as culture has been established. As long as youth entertainment has values that can be seen as going against the established values of the preceding generation, a moral panic could take place. The purpose of this research was to analyze how moral panics centered on youth entertainment begin and gain traction. To do this, the research was focused on the 1980s moral panic around tabletop roleplaying games, specifically�Dungeons & Dragons. By tracing the origin of the moral panic to the fear of cults and occult from the 1970s, we can find more context as to why some individuals believed that role playing games could cause adolescents to use the games as a style of dangerous escapism or as a gateway to the occult. To further understand this moral panic, an analysis of some of the major detractors of role playing games was done, as well as researching the role the media played in cultivating the moral panic. With a greater understanding on how moral panics begin and gain traction, this research can be used to compare and contrast other moral panics around youth entertainment.

    Infectious diseases caused by pathogenic microorganisms are major challenges despite all the steps taken to control or cure. New drug development with high efficacy/selectivity for infectious diseases is a point of interest for many researchers. It has reported that tuberculosis is one of the ten major causes of death in the world. Multi-drug resistance (MDR) is another major concern in bacterial and fungal infections. The present study deals with the development of new conjugates of pyrazinoic acid and isoniazid linked via an amino acid. The synthesized conjugates show promising and interesting results against a variety of microbial strains, tuberculous and non-tuberculous mycobacteria. Molecular modeling studies were used for understanding and validation of the experimental data.
  • THE SUBLETHAL EFFECTS AND BIOACCUMULATIONS OF 17-ALPHA-ETHNIYL ESTRADIOL IN LUMBRICULUS VARIEGATUS

    Ogun-Semore, Kikelomo; Department of Biological Sciences; Wiley, Faith; Augusta University (2019-02-13)
    Freshwater sources are subject to contamination from toxic compounds and other harmful materials through improper sewage cleanup and pollution. Ethinyl estradiol (EE), a synthetic, steroidal estrogen used in contraception, is present in varying concentrations across freshwater sources worldwide. EE is also classified as an endocrine disruptor that is known to interfere with the endocrine system. Endocrine disruptors can create adverse effects on bodily systems and have been found to affect behavioral patterns, enzymatic activity levels, and estrogen receptor levels. Preceding data has found that EE exposure leads to an increase in mortality, a decrease in offspring, and changes in reproductive morphology among freshwater invertebrates. The objective of this study was to observe the sublethal effects and bioaccumulation of ethinyl estradiol in Lumbriculus variegatus. Data collection on experimental endpoints, including reproduction rate, segment regrowth of L. variegatus, have been collected. The bioaccumulation of EE within L. variegatus was observed through sediment testing and an ethinyl estradiol ELISA. The data collected from this experiment contributes to information available on the effects of low-dosage endocrine disruptor concentrations on freshwater organisms. The effects of EE and its bioaccumulation could be extrapolated to include bioaccumulation of EE in organisms of higher trophic levels, including vertebrates.

    Aging is a multifarious natural process, linked with several biochemical and morphological variations in the biological system. Aging not only challenges the increased vulnerability as well as homeostasis network to the cognition and locomotion but also to physical, mental or social activities. Medicinal plants have been used since ancient time to cure and prevent various diseases. Several natural compounds such as isoflavones, anthocyanins, and catechins isolated from plant sources act as a potent antioxidant against ROS (Reactive Oxygen Species).�Antioxidants, especially natural antioxidants are recommended for the prevention of aging. In this study, we utilized an unexplored traditional medicinal plant�Aporosa octandra�(Buch.-Ham. ex D. Don) that�belongs to the family�Euphorbiaceae,�sub-family Phyllanthaceae that is shrub to tree, up to 15 m high and comprises of 50 species, which are distributed throughout Asian regions. This plant is enlisted as a medicinal plant and is used for centuries in the Ayurvedic system. We investigated phytochemical contents of the plant and evaluated the biological activity.
