Effect Of Estrogen Pretreatment On Glial-Like Cell Viability Following Stress Response Hormone Treatment, Bridget N. Smith, Kevin S. Burgess, Kathleen S. Hughes

Georgia Journal of Science

The role of steroid hormones is critical in cellular function. Previous studies have found a positive correlation between the endogenous estrogen 17β-estradiol and cellular protection. Conversely, exogenous conjugated equine estrogens provide less protective mechanisms than endogenous hormones, and little is known about the role of estrogens in cellular protection during a stress response. In the present study, we compare the effects of short-term estrogen pretreatments (alone and in combination) on cell viability when cells with glial cell morphology are exposed to either epinephrine or cortisol. Results showed that 1 µM 17β-estradiol resulted in decreased cell viability following the epinephrine treatment; …

Comparing Allelochemicals Of ​English Ivy And Native Georgia Plants​, Rebecca Senft

Symposium of Student Scholars

English Ivy (Hedera helix L.) is a common invasive plant causing biodiversity losses across the southeast and parts of the northwestern US. The mechanisms by which Ivy invades native ecosystems are not well understood but may include allelopathy, a process through which one species produces biochemicals that disrupt competitors. These biochemicals are often produced and exuded by roots into soil, making them difficult to isolate. This study used a soil-less hydroponic system and gas-chromatography mass spectroscopy to examine differences in the chemicals produced by roots of native Georgia plants and English Ivy. Our results suggest there are differences in the …

Binding Affinity And Interaction Of Sars-Cov-2 Epitopes With Major Histocompatibility Complex, Sareena Kandavalli, James Stewart, Mohammed A. Halim

Symposium of Student Scholars

SARS CoV-2 has been affecting the world since 2019. It caused 245 million cases of infection and around 5 million deaths worldwide. The most important strategies for the development of vaccines against SARS-CoV-2 are inactivated or weakened virus, replicating or non-replicating viral vector-based approaches, DNA, RNA, virus particle like approaches and epitope-based approaches. The epitope-based approach is rapid, accurate, cost-effective, and reliable against pathogens. By presenting epitopes (antigen peptides) on antigen-presenting cells (APCs), the major histocompatibility complex (MHC), also recognized as the human leukocyte antigen (HLA) system in humans, plays an essential role in triggering T-cell immune responses. The focus …

Pilot Study Exploring The Impact That Laboratory ​Instruction Has On A Student's Stem Professional Identity​ ​, Datiel Dayani, Dr. Michelle Head, Amjad Alkawam, Emma Pearman

Symposium of Student Scholars

STEM professional identity serves as one lens through which researchers have used to study factors that influence achievement in chemistry courses and persistence in a STEM major. The literature has proposed that the high attrition rate among STEM majors may result from the student’s evolving professional identity, motivational factors, and how they correlate a STEM career to their future aspirations. There is limited insight into how laboratory classes and teaching practices affect a student’s professional identity development. To investigate this, this study employed James Marcia’s identity development theory to understand the relationship between a student's identity status and their perception …

Cell Penetrating Peptide Inhibiting The Main Protease Of Sars-Cov-2, Adam Ashley, James Stewart, Mohammad Halim

Symposium of Student Scholars

As of October 2021, SARS-CoV-2 has infected over 244 million people and killed about 5 million people. The current FDA approved vaccines are effective; however, they lose their effectiveness after a few months of receiving both doses of the vaccine, and it is recommended to get a booster shot six months after receiving the second dose of the vaccine. Therefore, new highly effective, long lasting antiviral agents and strategies are needed to create an alternative treatment for SARS-CoV-2 and the different variants. Previous studies have shown that cell penetrating peptides (CPPs) have led to greater efficiency of intracellular delivery. However, …

Seasonal shifts in phytoplankton accumulation and loss largely follow changes in mixed layer depth, but the impact of mixed layer depth on cell physiology remains unexplored. Here, we investigate the physiological state of phytoplankton populations associated with distinct bloom phases and mixing regimes in the North Atlantic. Stratification and deep mixing alter community physiology and viral production, effectively shaping accumulation rates. Communities in relatively deep, early-spring mixed layers are characterized by low levels of stress and high accumulation rates, while those in the recently shallowed mixed layers in late-spring have high levels of oxidative stress. Prolonged stratification into early autumn …

Simulation Of Pedestrian In Multifunctional Passageway Of Metro Station Area Based On Social Force Model, Wang Xi, Zhang Rui, Fei Shuo, Minghang Yang

Journal of System Simulation

Abstract: Transitional passageway connecting subway stations and commercial facilities is generally designed as the multifunctional passageway, in which the traffic function is the main and the service function is the auxiliary. The impact of the service facilities on both sides of the passage on pedestrian traffic is difficult to be quantitatively analyzed and simulated and modeled. Through measurement, it is found that the viscous effect of service facilities on pedestrian traffic is mainly slowing down the speed or changing the trajectory direction. Through analyzing the horizontal influence range of service facilities, dividing the passage into different areas, and introducing the …

Making Agriculture Carbon Neutral Amid A Changing Climate: The Case Of South-Western Australia, Ross Kingwell

Climate Science Research Articles

Making Australian agriculture carbon neutral by 2050 is a goal espoused by several agricultural organisations in Australia. How costly might it be to attain that goal, especially when adverse climate change projections apply to agriculture in southern Australia? This study uses scenario analysis to examine agricultural emissions and their abatement via reforestation in south-western Australia under projected climate change. Most scenarios include the likelihood of agricultural emissions being reduced in the coming decades. However, the impact of projected adverse climate change on tree growth and tree survival means that the cost of achieving agricultural carbon neutrality via reforestation is forecast …

Ticks (Acari: Ixodidae) Parasitizing Migrating And Local Breeding Birds In Finland, Jani J. Sormunen, Tero Klemola, Eero J. Vesterinen

Harold W. Manter Laboratory of Parasitology: Library Materials

Ticks are globally renowned vectors for numerous zoonoses, and birds have been identified as important hosts for several species of hard ticks (Acari: Ixodidae) and tick-borne pathogens. Many European bird species overwinter in Africa and Western Asia, consequently migrating back to breeding grounds in Europe in the spring. During these spring migrations, birds may transport exotic tick species (and associated pathogens) to areas outside their typical distribution ranges. In Finland, very few studies have been conducted regarding ticks parasitizing migrating or local birds, and existing data are outdated, likely not reflecting the current situation. Consequently, in 2018, we asked volunteer …

A Study In Soft Robotics: Metrics, Models, Control, And Estimation, Levi Thomas Rupert

Theses and Dissertations

Traditional robots, while capable of being efficient and effective for the task they were designed, are dangerous when operating in unmodeled environments or around humans. The field of soft robotics attempts to increase the safety of robots thus enabling them to operate in environments where traditional robots should not operate. Because of this, soft robots were developed with different goals in mind than traditional robots and as such the traditional metrics used to evaluate standard robots are not effective for evaluating soft robots. New metrics need to be developed for soft robots so that effective comparison and evaluations can be …

Complex tissue regeneration is extremely rare among adult mammals. An exception, however, is the superior tissue healing of multiple organs in spiny mice (Acomys). While Acomys species exhibit the remarkable ability to heal complex tissue with minimal scarring, little is known about their cardiac structure and response to cardiac injury. In this study, we first examined baseline Acomys cardiac anatomy and function in comparison with commonly used inbred and outbred laboratory Mus strains (C57BL6 and CFW). While our results demonstrated comparable cardiac anatomy and function between Acomys and Mus, Acomys exhibited a higher percentage of cardiomyocytes displaying …

The Puerto Rican Diaspora: Evaluating Constructions Of Race And Ethnicity, Megan E. Walter

Honors Theses

The Spanish first colonized Puerto Rico in the 16^th century. The implementation of slavery shaped cultural traditions, agricultural practices, and established a socio-racial hierarchy. When Puerto Rico was acquired by the United States, legal and economic changes intensified race relations and classism. These global powers established notions of race and ethnicity which continue to dominate diasporic and identity discourse. Nearly a century later, the lasting effects of imperialism have converged with two decades of recurrent calamities, resulting in mass migration off the island and growing Puerto Rican communities within the U.S., notably in New York and Florida. By tracing …

Leukotrienes Are Dispensable For Vaginal Neutrophil Recruitment As Part Of The Immunopathological Response During Experimental Vulvovaginal Candidiasis, Junko Yano, David J. White, Anthony P. Sampson, Floyd L. Wormley, Paul L. Fidel

School of Dentistry Faculty Publications

Recruitment of polymorphonuclear neutrophils (PMNs) into the vaginal lumen is the hallmark of an acute immunopathologic inflammatory response during vulvovaginal candidiasis (VVC) caused by Candida albicans. Recurrent VVC (RVVC) remains a chronic health burden in affected women worldwide despite the use of antifungal therapy. Based on the role leukotrienes (LTs) play in promoting inflammation, leukotriene receptor antagonists (LTRAs) targeted for LTB4 (etalocib) or LTC4, LTD4, and LTE4 (zafirlukast or montelukast) have been shown to reduce inflammation of epithelial tissues. An open-label pilot study using long-term regimens of zafirlukast in women with RVVC indicated the potential for some relief from recurrent …

Western North American Naturalist

Accurate information on species identities and distributions is critical for informing state land use and conservation policies. However, it can often be difficult to determine species identity using morphological data alone. Using phylogenetic methods, we determined the identity of Sceloporus lizards occupying the Laramie Mountains of Wyoming, between known ranges for Sceloporus tristichus and Sceloporus consobrinus. The ND1 mitochondrial gene was sequenced for 10 individuals from the Laramie Mountains and analyzed using maximum likelihood with 23 other samples of S. tristichus and S. consobrinus from throughout their ranges. The mtDNA gene tree places the Laramie Mountains populations within a …

The Evolutionary Origins Of Autism Associated Genes And Their Role In Great Ape Socio-Communicative Behavior, Azeeza Abdulrauf

Master of Science in Integrative Biology Theses

Autism Spectrum Disorder (ASD) is a set of neurological disorders characterized by reduced social interactions and deficits in verbal and nonverbal communication. Although there are no clear genetic markers for ASD, studies have found associations between gene single nucleotide polymorphisms (SNPs) and patients diagnosed with ASD. For this study, the focus is on OXTR, AVPR1A, and FOXP2. OXTR is reported to regulate empathy and stress reactivity while AVPR1A is reported to regulate stress management and territorial aggression, as well as social bonding and recognition. FOXP2 is one of the first genes to be associated with both speech and language recognition …
