Validating An Automated Classification System For Snake Movement Behavior: Refining And Extending The Radio Telemetry-Accelerometry Framework, Dominic L. Desantis

College of Arts and Sciences

An animal’s behavioral decisions, such as when, why, and how individuals move through their environment, are mediated by a complex interplay between internal (e.g., sex, physiological state, motivational state) and external (e.g., environmental conditions, predation, competition) factors. A detailed understanding of the causes and consequences of these decisions for many species has historically been precluded by methodological constraints. However, a recent wave of advancements in sensor technologies circumvents many of these traditional limitations and has spurred the emerging field of biologging science. Animal-attached dataloggers (or biologgers) give researchers the ability to remotely monitor an individual’s physiology and behavior in the …

A Zugunruhe Data Collection System Using Passive Infrared Sensors, Ryan Terry, Luis E. Ramirez, Carol Carrera, Abigail Kimmitt, Kira Delmore, Ana Goulart

Pursue: Undergraduate Research Journal

When engineers and biologists work together, there is a lot to learn on both sides. For instance, our work introduced us to zugunruhe, which is a German word that means “unrest”. It is used in the context of migratory birds, as they become restless at night, inside their cages, during their migratory period. When does zugunruhe start? It usually starts when the weather becomes cold and the days shorter, but it varies for different bird species. Moreover, global warming has caused changes in zungunruhe’s timing, which made it even harder to predict. Another question is about genetics: is …

A Morphological And Molecular Analysis Of A Bloom Of The Filamentous Green Alga Pithophora, Blia Lor, Merry Zohn, Marcus J. Meade, A. Bruce Cahoon, Kalina M. Manoylov

Faculty and Staff Works

Filamentous representatives of Cladophorales (Chlorophyta) are major contributors to algal biomass of littoral communities. In the present study, community analysis of a reported bloom in the Ogeechee River in Georgia provided an opportunity to combine morphological and genetic analyses with ecological information related to an understudied nuisance alga. A polyphasic approach of incorporating genotypic and phenotypic methods led to the identification of the algal community as Pithophora roettleri (Roth) Wittrock. Morphological analysis showed a monospecific community based on the average length and diameter of the heterosporous intercalary and terminal akinetes, along with the diameter of the principal filaments. Single-gene and …

Epitranscriptomic Writer Regulation Of Gene Expression In Escherichia Coli, William Eugene Gasperi

Legacy Theses & Dissertations (2009 - 2024)

The epitranscriptome is composed of enzyme catalyzed RNA modifications that can regulate tRNA, mRNA, and rRNA structure and function. RNA modifications can play key roles in regulating gene expression by controlling the when and how much of translation of specific transcripts. The SelU catalyzed tRNA wobble uridine (U) modification, occurs on tRNA lysine, glutamic acid, and glutamine. We have shown that E. coli deficient in selU gene are more sensitive to the antibiotic chloramphenicol (CAM) than their wild type counterparts. CAM works by inhibiting protein synthesis by binding to the ribosome and preventing peptide chain formation. We hypothesize that SelU …

An Exceptionally Small New Polycotylid Plesiosaur (Reptilia: Sauropterygia) With Raptorial Eyes From The Western Interior Seaway Of North America, Robert O’Brien Clark

Theses, Dissertations and Capstones

Polycotylidae is a family of plesiosaurian marine reptiles that evolved during the Early Cretaceous and radiated into multiple genera during the Late Cretaceous, achieving a worldwide distribution. Derived polycotylids of the subclade Polycotylinae have a gracile and elongated rostrum, homodont dentition, an extended mandibular symphysis, and foreshortened temporal fenestrae. In this thesis, I describe a small and highly derived new polycotylid taxon based on three specimens from the Campanian of the Western Interior Seaway in North America. A high number of maxillary teeth, fused neural arches, propodials with well-defined facets, and heavily remodeled cortical bone indicate the specimens are adults, …

Pleistocene Rodents From Southeast Georgia, Parker Rhinehart

Graduate Research Showcase

Late-Pleistocene fossil sites are uncommon in Georgia. However, Clark Quarry, a locality near Brunswick, Georgia, has yielded a large and diverse collection of vertebrate skeletal material dominated by cranial and post-cranial fossils of Columbian mammoths (Mammathus columbi) and giant bison (Bison latifrons). Screen washing of the fossiliferous sediment associated with the bones of the megafauna has produced a large number of microfossils. Here I describe fossil rodents from Clark Quarry. Cranial and post-cranial material of eight rodent taxa have been identified to date. Of these, five are found in the area today: Sigmodon hispidus, Peromyscus sp., …

New Benzoxazole Derivatives As Antiprotozoal Agents: In Silico Studies, Synthesis, And Biological Evaluation, Mohamed A. Abdelgawad, Mohammad M. Al-Sanea, Mohamed A. Zaki, Enas I.A. Mohamed

Faculty and Student Publications

Background. Benzoxazole derivatives have different biological activities. In pursuit of designing novel chemical entities with antiprotozoal and antimicrobial activities, benzoxazolyl aniline was utilized as a privileged scaffold of a series of (3-benzoxazole-2-yl) phenylamine derivatives, 3-benzoxazoloyl acetamide, and butyramide derivatives. Methods. These novel analogs were synthesized in straightforward simple chemistry without any quantitative chromatographic separations in reasonable yields. The biological evaluation of all target compounds as potential antimalarial, antileishmanial, antitrypanosomal, and antimicrobial agents was performed by various well-established cell-based methods. Results. Compounds 6d and 5a showed promising biological screening data. The amidation of 3-benzoxazolyl aniline 1 with the chloroacetyl functional group …

Mythopoetic Naturalization: Toward A New Paradigm Of Reifcation, Bryan Smyth

Faculty and Student Publications

This paper sketches a new approach to the critical-theoretic problem of reifcation understood as a normatively problematic form of naturalizing or dehistoricizing entifcation. Entifcation in general is approached phenomenologically in terms of the mythic outer horizonality of the lifeworld, and reifcation is shown to stem from the dichotomy between nature and history which, along with a corresponding dichotomy between myth and reason, is characteristic of Enlightenment rationality. Dereifcation necessitates overcoming these dichotomies, and this implies a critical embrace of myth and mythopoesis in the sense of instituting more normatively appropriate lifeworld horizons. While classical Marxism and radical social theory have …

Longitudinal Analysis Of Dengue Virus–Specific Memory T Cell Responses And Their Association With Clinical Outcome In Subsequent Denv Infection, Luis Alberto Sanchez-Vargas, Kathryn B. Anderson, Anon Srikiatkhachorn, Jeffrey R. Currier, Heather Friberg, Timothy P. Endy, Stefan Fernandez, Anuja Mathew, Alan L. Rothman

Cell and Molecular Biology Faculty Publications

Memory T cells resulting from primary dengue virus (DENV) infection are hypothesized to influence the clinical outcome of subsequent DENV infection. However, the few studies involving prospectively collected blood samples have found weak and inconsistent associations with outcome and variable temporal trends in DENV-specific memory T cell responses between subjects. This study used both ex-vivo and cultured ELISPOT assays to further evaluate the associations between DENV serotype-cross-reactive memory T cells and severity of secondary infection. Using ex-vivo ELISPOT assays, frequencies of memory T cells secreting IFN-γ in response to DENV structural and non-structural peptide pools were low in PBMC from …

Cell and Molecular Biology Faculty Publications

Background

Human mobility among residential locations can drive dengue virus (DENV) transmission dynamics. Recently, it was shown that individuals with symptomatic DENV infection exhibit significant changes in their mobility patterns, spending more time at home during illness. This change in mobility is predicted to increase the risk of acquiring infection for those living with or visiting the ill individual. It has yet to be considered, however, whether social contacts are also changing their mobility, either by socially distancing themselves from the infectious individual or increasing contact to help care for them. Social, or physical, distancing and caregiving could have diverse …

Monomeric Iga Antagonizes Igg-Mediated Enhancement Of Denv Infection, Adam D. Wegman, Hengsheng Fang, Alan L. Rothman, Stephen J. Thomas, Timothy P. Endy, Michael K. Mccracken, Jeffrey R. Currier, Heather Friberg, Gregory D. Gromowski, Adam T. Waickman

Cell and Molecular Biology Faculty Publications

Dengue virus (DENV) is a prevalent human pathogen, infecting approximately 400 million individuals per year and causing symptomatic disease in approximately 100 million. A distinct feature of dengue is the increased risk for severe disease in some individuals with preexisting DENV-specific immunity. One proposed mechanism for this phenomenon is antibody-dependent enhancement (ADE), in which poorly-neutralizing IgG antibodies from a prior infection opsonize DENV to increase infection of F_c gamma receptor-bearing cells. While IgM and IgG are the most commonly studied DENV-reactive antibody isotypes, our group and others have described the induction of DENV-specific serum IgA responses during dengue. We …

The oceans’ uptake of anthropogenic carbon dioxide (CO₂) decreases seawater pH and alters the inorganic carbon speciation – summarized in the term ocean acidification (OA). Already today, coastal regions experience episodic pH events during which surface layer pH drops below values projected for the surface ocean at the end of the century. Future OA is expected to further enhance the intensity of these coastal extreme pH events. To evaluate the influence of such episodic OA events in coastal regions, we deployed eight pelagic mesocosms for 53 days in Raunefjord, Norway, and enclosed 56–61 m³ of local seawater …

Fitness Of Interspecific Hybrids In The Genus Cyprinella: An Evaluation Of Swimming Performance In Stream Fishes, Jessica K. Wilks, Gregory J. Glotzbecker, Gary D. Grossman, Michael J. Blum

Graduate Research Showcase

As the result of anthropogenic disturbance, freshwater ecosystems are rapidly being destroyed worldwide. Accordingly, such impacts are also resulting in the loss of aquatic biodiversity. Specifically, the introduction of non-native aquatic species is becoming an increasing concern. Historically, many non-native freshwater fish introductions have been the result of commercial baitfish aquaculture and private aquarium release. Cyprinella lutrensis (the red shiner) is endemic to much of the central U.S., and its natural range does not extent east of the Mississippi River. Since the 1950’s, red shiner have been cultivated and transported across the globe as both bait and aquarium fish. During …

Monitoring Lake Sinclair, Margaret Blackledge

Graduate Research Showcase

Algae, a polyphyletic group of aquatic primary producers, play a great part in earth’s biosphere. They produce half of the world’s oxygen and are major contributors to aquatic biodiversity. When conditions are favorable to a species, algae will bloom. Some algal species will produce algal toxins during a bloom as a potential mechanism to concentrate carbon. Due to the integral part they play in aquatic food webs, nutrient cycling and the potential for harmful algal blooms, algal communities are monitored to determine the health and safety of aquatic environments. Lake Sinclair in middle Georgia is a good model where in …

Technology Or Taboo?: An Analysis Of Emerging Technology Weapons And Weapon Taboos, Mia R. Wilson

Honors Undergraduate Theses

Technology tends to evolve over time, leading over things to evolve with it. One example may be the evolution of weapons with technological advancement. When these weapons change, it changes how war is conducted. This paper seeks to delve into the specifics of this phenomena. With technological advancement, the world has seen new threats such as lethal autonomous weapons (LAWs) and cyber weapons. New weapons have been, at times, too threatening. They have created so much stigma around themselves the international community ultimately decided against their use. These weapons may then receive a weapon taboo, discouraging their use.

Cytotoxic Effects Of 5-Azacytidine On Primary Tumour Cells And Cancer Stem Cells From Oral Squamous Cell Carcinoma: An In Vitro Ftirm Analysis, Valentina Notarstefano, Alessia Belloni, Simona Sabbatini, Chiara Pro, Giulia Orilisi, Riccardo Monterubbianesi, Vincenzo Tosco, Hugh Byrne, Lisa Vaccari, Elisabetta Giorgini

Articles

In the present study, the cytotoxic effects of 5-azacytidine on primary Oral Squamous Cell Carcinoma cells (OSCCs) from human biopsies, and on Cancer Stem Cells (CSCs) from the same samples, were investigated by an in vitro Fourier Transform InfraRed Microscospectroscopy (FTIRM) approach coupled with multivariate analysis. OSCC is an aggressive tumoral lesion of the epithelium, accounting for ~90% of all oral cancers. It is usually diagnosed in advanced stages, and this causes a poor prognosis with low success rates of surgical, as well as radiation and chemotherapy treatments. OSCC is frequently characterised by recurrence after chemotherapy and by the development …

What Common Factors May Influence The Success Of Dental Implant?, Yehuda Taavar

The Science Journal of the Lander College of Arts and Sciences

The aim of this study is to investigate the common factors that may influence the success of dental implants. Addressing these factors may potentially aid experts in the field in delivering dental implants without approaching or decreasing the number of failures. Smoking, diabetes, implant maintenance, age, and implant size have significantly influenced implant success. It is suggested that patients are advised to quit smoking at least one week before surgery to minimize risk factors. Inadequate glycemic control also contributes to periodontal destruction and is associated with the severity of peri-implant complications. However, if patients maintain good glycemic control, dental implants …
