Mechanisms Regulating Photoreceptor Subtype Specification And Chromophore Utilization In Zebrafish, Leo Volkov

Arts & Sciences Graduate Student Theses and Dissertations

The first step in vision is the detection of light by a photoreceptor cell. The spectral sensitivity of a photoreceptor, in turn, is determined by the composition of its visual pigment, which consists of an opsin protein and a covalently bound chromophore derived from either vitamin A1 or vitamin A2. In the course of evolution, opsin gene duplication and functional divergence led to the emergence of four distinctive cone opsins, maximally sensitive to ultraviolet (UV), blue, green, or red light, as well as the rod opsin. Subsequently, the expression of these functionally distinct opsins was segregated into distinct cell types …

“Have You Seen Me?”: Forensic Art For Human Identification, Mckenzie Stommen

Honors Theses

Forensic art for human identification is used to identify victims, suspects, and unidentified decedents. The field is highly interdisciplinary, and forensic artists draw on a broad range of skills, knowledge, and relationships with colleagues to complete this work. This paper will focus mainly on age progression and forensic facial reconstruction, although more applications of forensic art do exist. The case study in forensic art discussed here took the form of an age progression.

New developments in artificial intelligence, facial recognition, computed tomography, and DNA have implications for forensic art, and have already begun to find a place in the field. …

Tiam1-Mediated Synaptic Plasticity Underlies Comorbid Depression-Like And Ketamine Antidepressant-Like Actions In Chronic Pain, Qin Ru, Yungang Lu, Ali Bin Saifullah, Francisco A Blanco, Changqun Yao, Juan P Cata, De-Pei Li, Kimberley F Tolias, Lingyong Li

Faculty, Staff and Students Publications

Chronic pain often leads to depression, increasing patient suffering and worsening prognosis. While hyperactivity of the anterior cingulate cortex (ACC) appears to be critically involved, the molecular mechanisms underlying comorbid depressive symptoms in chronic pain remain elusive. T cell lymphoma invasion and metastasis 1 (Tiam1) is a Rac1 guanine nucleotide exchange factor (GEF) that promotes dendrite, spine, and synapse development during brain development. Here, we show that Tiam1 orchestrates synaptic structural and functional plasticity in ACC neurons via actin cytoskeleton reorganization and synaptic N-methyl-d-aspartate receptor (NMDAR) stabilization. This Tiam1-coordinated synaptic plasticity underpins ACC hyperactivity and drives chronic pain-induced depressive-like behaviors. …

The Enemy Within: An Investigation Of The Intracellular Bacteria In Urinary Tract Infections, Jennie Elizabeth Hazen

Arts & Sciences Graduate Student Theses and Dissertations

Urinary tract infections (UTIs) are common diseases that are associated with significant morbidities. Multiple studies have indicated that multiple species of uropathogenesis bacteria invade and persist within bladder epithelial cells as a necessary step of uropathogenesis. Interestingly, many of these species are not canonically associated with intracellular infections. Although the first study describing bacteria within the urothelium was published two decades ago, this critical step of uropathogenesis remains relatively understudied.I established a murine model of community-acquired A. baumannii UTI, a previously unstudied manifestation of the disease. While immunocompetent mice resolved their infections quickly, immunocompromised mice displayed high bacterial burdens throughout …

This dissertation covers a wide range of topics but is linked by the common theme of radiation interacting with materials and studying the result of those interactions. The introduction describes the fundamentals of how radiation interacts with material and how we are able to detect that radiation and the application of how we use those interactions in radiation oncology. The thesis starts with a chapter detailing the temperature dependence of the photophysics in two organic scintillators. This chapter is the foundation for a future study that will look the degree to which these scintillators can distinguish between gammas and neutrons …

Review Of The Physical And Chemical Properties Of Seagrass Soils, Nerea Piñeiro-Juncal, Oscar Serrano, Miguel Ángel Mateo, Elena Diaz-Almela, Carmen Leiva-Dueñas, Antonio Martinez-Cortizas

Research outputs 2022 to 2026

Seagrasses are a polyphyletic group of angiosperms that colonized marine environments more than 30 million years ago and currently inhabit coastal soft and rocky substrates in all continents except Antarctica. Due to their evolution from terrestrial plants, seagrasses have belowground organs that interact with the substrate, transforming it through chemo-physical processes analogous to terrestrial soil formation. Although seagrass substrates provide valuable ecosystem services including carbon and coastal stabilization, they have been largely regarded as sediments by marine scientists and neglected in soil science research. However, over the last decades, the increasing interest in carbon accumulation by seagrasses has generated multiple …

Mitochondria Clumping Vs. Mitochondria Fusion In Cmt2a Diseases, Antonietta Franco, Caroline E Walton, Xiawei Dang

2020-Current year OA Pubs

Phenotypic variations in Charcot-Marie-Tooth disease type 2A (CMT2A) result from the many mutations in the mitochondrial fusion protein, mitofusin 2 (MFN2). While the GTPase domain mutations of MFN2 lack the ability to hydrolyze GTP and complete mitochondrial fusion, the mechanism of dysfunction in HR1 domain mutations has yet to be explored. Using

Human Nk Cells Confer Protection Against Hiv-1 Infection In Humanized Mice, Can M. Sungur, Qiankun Wang, Ayşe N. Ozantürk, Hongbo Gao, Aaron J. Schmitz, Marina Cella, Wayne M. Yokoyama, Liang Shan

2020-Current year OA Pubs

The role of NK cells against HIV-1 infections remains to be elucidated in vivo. While humanized mouse models potentially could be used to directly evaluate human NK cell responses during HIV-1 infection, improved functional development of human NK cells in these hosts is needed. Here, we report the humanized MISTRG-6-15 mouse model, in which NK cells were quick to expand and exhibit degranulation, cytotoxicity, and proinflammatory cytokine production in nonlymphoid organs upon HIV-1 infection but had reduced functionality in lymphoid organs. Although HIV-1 infection induced functional impairment of NK cells, antiretroviral therapy reinvigorated NK cells in response to HIV-1 rebound …

Primates And Birds Of Sabulungan; Roles Of Animals In Sculptures, Shamanic Songs And Dances, And The Belief System Of Traditional Mentawaians, Juniator Tulius, Linda Burman-Hall

Wacana, Journal of the Humanities of Indonesia

Mentawaians sing ritual songs enshrined in archaic texts referring to particular primates and birds, while ritual and traditional dances imitate how gibbons, sea eagles, and other animals live in the natural world. Mentawaians craft sculptures of endemic primates and unique birds. The bilou gibbon ape and various other animals also symbolize specific sacred knowledge within the sabulungan spiritual belief system and traditional cosmology of Mentawai society. Although some do succeed in surviving, many older traditions have faded away. Among the traditions which continue intact, this report aims to examine the roles of primates and birds across the arts and in …

Honey-Bees, Court Ladies, And Beekeeping In Java Before 1500 Ce, Jiří Jákl

Wacana, Journal of the Humanities of Indonesia

People have been interacting with bees in the Indo-Malay world for thousands of years. Though the practice of robbing bees of honey and wax is relatively well-documented, we know very little about the early history of beekeeping in Southeast Asia. In this study I will use Old Javanese evidence to demonstrate that providing honey bees with artificial cavities was a practice known in Java at least by the twelfth century CE, several centuries earlier than suggested by the historians of beekeeping. In the second part of my contribution I will discuss in detail an intriguing passage in the Sumanasāntaka, a …

Loving Nature, Praising The Creator; The Visualizations Of The Natural World In The Islamic Magazine Pandji Masjarakat, Muhammad Yuanda Zara

Wacana, Journal of the Humanities of Indonesia

This study examines previously unexplored visual representations of the natural world published in Pandji Masjarakat magazine in 1960. Known at the time as the most popular Islamic magazine in Indonesia, this publication not only discussed Islamic teachings as hitherto understood, but also provided ample space for the publication of drawings, paintings, and photographs of the natural world. This study argues that the visualizations of the natural world in Pandji Masjarakat were aimed at providing its Muslim readers all over Indonesia and in the wider Malay world with guidance on how to see the natural world and people’s place in it …

Mount Merapi In Drawings And Paintings; A Dynamic Reflection Of Nature, 1800-1930, Ghamal Satya Mohammad

Wacana, Journal of the Humanities of Indonesia

Mount Merapi in Central Java is one of the world’s most studied volcanoes. The frequent eruptions of this volcano and the densely populated areas on its slopes make Merapi particularly important to scholars of the natural and social sciences. Considerable attention has been devoted to contemporary aspects of this volcano, including research into forecasting and monitoring possible volcanic activity and eruptions. However, research investigating artistic representations of Merapi in a historical context, particularly local artworks referring to how people responded to a natural hazard such as a volcanic eruption, is still rare. In this paper, I explore how artists in …

Matters Of Perspective; Local Visual Expertise And Natural History Drawings In Java, 1820-1850, Andreas Weber, Sylvia Van Zanen

Wacana, Journal of the Humanities of Indonesia

This essay examines how local draughtsmen using their visual expertise shaped natural historical knowledge production in colonial Indonesia in the early nineteenth century. The persons at the core of this essay are Tsing Wang Ho and Pieter van Oort, both draughtsmen who worked for the Natuurkundige Commissie voor Nederlandsch-Indië (Committee of Natural History of the Netherlands Indies). By zooming in on the Committee’s fieldwork in Java in the 1830s, this essay highlights that producing scientific drawings of animals and plants was a challenging endeavour. Despite detailed instructions from Europe and the logistical support of the colonial government in Batavia, the …

Treatment Of The Mentally Ill In The U.S. Gilded Age, Madeline Whelan

Honors Program Theses and Projects

The maltreatment of the working class and immigrants was quite prominent throughout the Gilded Age of the United States. The endless capitalist desires of a growing industrial nation often left American laborers at the mercy of corporations and businessmen. Workers endured strenuous labor, hazardous work environments, and unjust management; yet, earned barely enough money to pay for their rent, let alone food and other necessities. Immigrants flooded the country with hopes of securing profit for their relatives back home, only to encounter inhumane working conditions and prejudice from nativists. As the distribution of wealth between laborers and the middle and …

Feminism And Women's Representation In Argentina, Devyn Murphy

Honors Theses

The theory of feminism has proved essential in the transformation of the patriarchal society in Argentina. Feminism paved the way for the emergence of various women’s movements, such as the Encuentros and Movimiento Nacional de Mujeres. These movements redefined the roles that women could play in society. It was because of this theory, and the movements, which made the theories a practice that advanced the political rights of Argentine women.

Effect Of Climate History On The Genetic Structure Of An Antarctic Soil Nematode, Abigail C. Jackson

Theses and Dissertations

Historical climate disturbances such as glacial cycling and fluctuating stream, lake, and sea levels strongly influence the distribution and evolutionary trajectories of Antarctic terrestrial species. Antarctic invertebrates, with limited long-range mobility, including the ubiquitous sentinel nematode species Scottnema lindsayae, are especially sensitive to climate disturbances. We tested hypotheses associated with the historical geographic and population genetic structure of this species as it occurs across the McMurdo Dry Valleys (MDVs) of Antarctica. In order to reconstruct the influence of climate disturbance and ecological conditions on this species, partial mitochondrial COI gene sequences were sequenced and analyzed from individual S. lindsayae collected …

Department of Chemistry: Faculty Publications

The growing demand of society for gas sensors for energy-efficient environmental sensing stimulates studies of new electronic materials. Here, we investigated quasi-one-dimensional titanium trisulfide (TiS₃) crystals for possible applications in chemiresistors and on-chip multisensor arrays. TiS₃ nanoribbons were placed as a mat over a multielectrode chip to form an array of chemiresistive gas sensors. These sensors were exposed to isopropanol as a model analyte, which was mixed with air at low concentrations of 1–100 ppm that are below the Occupational Safety and Health Administration (OSHA) permissible exposure limit. The tests were performed at room temperature (RT), as …

Predicted Episode Of Submarine Groundwater Discharge Onto The South Carolina, Usa, Continental Shelf And Its Effect On Dissolved Oxygen, Wilson S. Moore, Jacob Vincent, James L. Pickney, Alicia M. Wilson

Faculty Publications

Submarine groundwater discharge (SGD) may directly influence the dissolved oxygen (DO) content of coastal bottom waters. Here, we report a predicted episode of enhanced SGD that caused low DO concentrations on the South Carolina continental shelf. The prediction model linked episodes of SGD to upwelling-favorable winds. The data revealed these waters were a factor of 2–6 higher in ²²⁶Ra and ²²⁸Ra compared to typical bottom water values and were significantly depleted in DO (<130 μM). The tight ²²⁸Ra:²²⁶Ra correlation of these data was similar to values during a strong hypoxic event off SC in 2012. Water ages from …

Some Epistemological And Ontological Reflections On Concept Of Causality: From Scientific Causality To Contextual Causality Some Epistemological And Ontological Reflections On Concept Of Causality: From Scientific Causality To Contextual Causality, Mohamed S. Hassan, Engy H Abdel Hafez

Journal of Arts and Social Sciences

This research tries to present a critical analysis of the concept of scientific causality and the problems it entails within the scientific domain. This study claims that scientific causality is not enough to understand the nature of relationships existing among the members of a chain and it is concerned with the possible action of correspondence apart from the context of action. It is argued here that all types of scientific causality fail to reflect the flexible nature of members of any possible correlation. This paper offers the concept "contextual causality" as a possible alternative perspective that reflects both the variable …
