Role Of Host Cell Β-Catenin During Toxoplasma Gondii Infection, Cameron H. Ranken Jul 2019

Role Of Host Cell Β-Catenin During Toxoplasma Gondii Infection, Cameron H. Ranken

Biology ETDs

The microbial pathogen Toxoplasma gondii is an intracellular protozoan that actively invades host cells and simultaneously creates a specialized parasitophorous vacuole within which the parasite lives and replicates. The parasite molecular machinery that drives establishment of the intracellular niche is relatively well known. However, it is now emerging that Toxoplasma exploits less well-understood host cell components to enable successful infection. Here, we examined the role of host Wnt/β-catenin during T. gondii infection. Using human fibroblasts and a mouse dendritic cell line, we found that infection with Toxoplasma stimulated both upregulation and nuclear localization of β-catenin. Using a transwell experimental approach, …

Ecological And Morphological Response Of Rodents To Environmental Change Over The Late Quaternary, Catalina Tomé Jul 2019

Ecological And Morphological Response Of Rodents To Environmental Change Over The Late Quaternary, Catalina Tomé

Biology ETDs

The rapid progression of modern climate change is already altering ecosystems worldwide. By employing the fossil record, we can investigate how animals responded to past climatic changes and biodiversity loss. The paleontological record of the late Quaternary (past ~22000 years) encompasses a period of considerable environmental change in North America. Rising temperatures and climatic fluctuations are coupled with the extinction of the majority of large bodied mammals on the landscape. The combination of climate and extinction events led to changes in vegetation and community structure which likely affected the resources available and interactions between the remaining mammals within communities. Here, …

Forty Years Of Change In Southwestern Bee Assemblages, Catherine Cumberland Jul 2019

Forty Years Of Change In Southwestern Bee Assemblages, Catherine Cumberland

Biology ETDs

Changes in a regional bee assemblage were investigated by repeating a 1970s study from the U.S. Southwest of bees visiting native sunflower (Helianthus annuus). Results showed declines in abundance and species richness of native bees and increases in non-native Apis mellifera. Climate data indicate drought increased over the 40-year period, favoring introduced and generalist species. Experimental placement of A. mellifera in an area of low A. mellifera density in New Mexico reduced native bee visitation, but improved reproduction in H. annuus plants. Meta-analytic models comparing pollination effectiveness in specialist versus generalist, native versus non-native, and native pollinators …

Constraining The Oxygen Values Of The Late Cretaceous Western Interior Seaway Using Marine Bivalves, Camille H. Dwyer Jul 2019

Constraining The Oxygen Values Of The Late Cretaceous Western Interior Seaway Using Marine Bivalves, Camille H. Dwyer

Earth and Planetary Sciences ETDs

The Western Interior Seaway (WIS) remains an oceanographic enigma, including its circulation, similarity to the open ocean, and the fidelity of geochemical proxies to reconstruct paleoenvironments. Across the late Campanian and early Maastrichtian I test whether: 1) the WIS had unique δ18OVPDB compared to other marine settings, 2) increasing oceanographic restriction changed the stable isotope composition, and 3) biases, e.g., taxonomy or diagenesis, influenced stable isotope compositions. Results indicate distinct δ18OVPDB in the WIS compared to other marine settings. δ18OVPDB values were stable through time, suggesting insignificant oceanographic restriction and a …

Resaka Kolontsaina Le Raha (It Is About Cultures): Cultures And Foreign Language Teaching In Madagascar, Iarintsambatra Rijasoa Andriamanana Josoa Jul 2019

Resaka Kolontsaina Le Raha (It Is About Cultures): Cultures And Foreign Language Teaching In Madagascar, Iarintsambatra Rijasoa Andriamanana Josoa

Language, Literacy, and Sociocultural Studies ETDs

For years, teaching and learning a foreign language (FL) has been equated to exclusively discover and master that target language and its related cultures. There has not been any exploration of other features such as the native language and local cultures in a foreign language classroom. Using a participatory action research, the aim of this study was to tell the story of six Malagasy high school teachers collaborating in a Teacher Learning Community (TLC) to construct and put into practice pedagogical approaches that celebrate and sustain Malagasy students’ identities, cultures, and experiences through classroom activities, and capitalize them for basis …

Indirect Effects In A Planktonic Disease System, Zoi Rapti, Tara E. Stewart Merrill, Liam E. Mueller-Brennan, Jerry H. Kavouras, Carla E. Cáceres Jul 2019

Indirect Effects In A Planktonic Disease System, Zoi Rapti, Tara E. Stewart Merrill, Liam E. Mueller-Brennan, Jerry H. Kavouras, Carla E. Cáceres

Biology Department Faculty Articles

Indirect effects, both density- and trait-mediated, have been known to act in tandem with direct effects in the interactions of numerous species. They have been shown to affect populations embedded in competitive and mutualistic networks alike. In this work, we introduce a four-dimensional system of ordinary differential equations and investigate the interplay between direct density-effects and density- and trait-mediated indirect effects that take place in a yeast parasite–zooplankton host–incompetent competitor system embedded in a food web which also includes resources and predators. Among our main findings is the demonstration that indirect effects cause qualitative and quantitative changes almost indistinguishable from …

Development Of Ni-Catalyzed Alkene Dicarbofunctionalization Reactions, Shekhar Kc Jul 2019

Development Of Ni-Catalyzed Alkene Dicarbofunctionalization Reactions, Shekhar Kc

Chemistry and Chemical Biology ETDs

Alkenes serve as one of the most important feedstocks for organic synthesis, having two vicinal sites for bond formation. In alkenes, both vicinal sites can be functionalized with two reagents in a process commonly known as alkene difunctionalization, which results in the formation of two new bonds. A number of alkenes difunctionalization reactions, such as diamination, dioxygenation, carboamination and carbooxygenation, are known. However, difunctionalization of alkenes with two carbon-based entities, termed alkene dicarbofunctionalization, is relatively less common. Development of such a process could provide a powerful method to introduce two different carbon fragments across an alkene in a regioselective manner, …

Computer Science Faculty Research and Publications

The Americans with Disabilities Act (ADA) is a civil rights law that was signed into law in 1992 by President George H.W. Bush. The law requires wheelchair access be made available for buildings built after 1992. Buildings under the law include retail stores, hotels, banks and most other public buildings. However, there are a large percentage of buildings built before 1992 that are not wheelchair accessible. In addition, ADA does not require the location of ramp to be at the front of the building. This is an inconvenience for individuals who use wheelchairs to access a building, as a) the …

Motor-Induced Suppression Of The N100 Event-Related Potential During Motor Imagery Control Of A Speech Synthesizer Brain–Computer Interface, Jonathan S. Brumberg, Kevin M. Pitt Jul 2019

Motor-Induced Suppression Of The N100 Event-Related Potential During Motor Imagery Control Of A Speech Synthesizer Brain–Computer Interface, Jonathan S. Brumberg, Kevin M. Pitt

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Speech motor control relies on neural processes for generating sensory expectations using an efference copy mechanism to maintain accurate productions. The N100 auditory event-related potential (ERP) has been identified as a possible neural marker of the efference copy with a reduced amplitude during active listening while speaking when compared to passive listening. This study investigates N100 suppression while controlling a motor imagery speech synthesizer brain–computer interface (BCI) with instantaneous auditory feedback to determine whether similar mechanisms are used for monitoring BCI-based speech output that may both support BCI learning through existing speech motor networks and be used as a …

Substituted Anthraquinones Represent A Potential Scaffold For Dna Methyltransferase 1-Specific Inhibitors, Rebecca L. Switzer, Jessica Medrano, David A. Reedel, Jill Weiss Jul 2019

Substituted Anthraquinones Represent A Potential Scaffold For Dna Methyltransferase 1-Specific Inhibitors, Rebecca L. Switzer, Jessica Medrano, David A. Reedel, Jill Weiss

Faculty Journal Articles

In humans, the most common epigenetic DNA modification is methylation of the 5-carbon of cytosines, predominantly in CpG dinucleotides. DNA methylation is an important epigenetic mark associated with gene repression. Disruption of the normal DNA methylation pattern is known to play a role in the initiation and progression of many cancers. DNA methyltransferase 1 (DNMT1), the most abundant DNA methyltransferase in humans, is primarily responsible for maintenance of the DNA methylation pattern and is considered an important cancer drug target. Recently, laccaic acid A (LCA), a highly substituted anthraquinone natural product, was identified as a direct, DNA-competitive inhibitor of DNMT1. …

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

Over the past decade, several large registries of patients with idiopathic pulmonary fibrosis (IPF) have been established. These registries are collecting a wealth of longitudinal data on thousands of patients with this rare disease. The data collected in these registries will be complementary to data collected in clinical trials because the patient populations studied in registries have a broader spectrum of disease severity and comorbidities and can be followed for a longer period of time. Maintaining the quality and completeness of registry databases presents administrative and resourcing challenges, but it is important to ensuring the robustness of the analyses. Data …

An Efficient Multiple-Place Foraging Algorithm For Scalable Robot Swarms, Qi Lu Jul 2019

An Efficient Multiple-Place Foraging Algorithm For Scalable Robot Swarms, Qi Lu

Computer Science ETDs

Searching and collecting multiple resources from large unmapped environments is an important challenge. It is particularly difficult given limited time, a large search area and incomplete data about the environment. This search task is an abstraction of many real-world applications such as search and rescue, hazardous material clean-up, and space exploration. The collective foraging behavior of robot swarms is an effective approach for this task. In our work, individual robots have limited sensing and communication range (like ants), but they are organized and work together to complete foraging tasks collectively. An efficient foraging algorithm coordinates robots to search and collect …

A hypothesis for the evolution of long post-reproductive lifespans in the human lineage involves asymmetries in relatedness between young immigrant females and the older females in their new groups. In these circumstances, inter-generational reproductive conflicts between younger and older females are predicted to resolve in favor of the younger females, who realize fewer inclusive fitness benefits from ceding reproduction to others. This conceptual model anticipates that immigrants to a community initially have few kin ties to others in the group, gradually showing greater relatedness to group members as they have descendants who remain with them in the group. We examine …

Epidermal Growth Factor Receptor Rs17337023 Polymorphism In Hypertensive Gestational Diabetic Women: A Pilot Study, Russell S. Martins, Taimur Ahmed, Sabah Farhat, Sana Shahid, Syeda Sadia Fatima

Medical College Documents

Background: Women with gestational diabetes mellitus have an increased risk of developing gestational hypertension, which can increase fetal and neonatal morbidity and mortality. In the past decade, single nucleotide polymorphisms in several genes have been identified as risk factors for development of gestational hypertension. The epidermal growth factor receptor activates tyrosine kinase mediated blood vessels contractility; and inflammatory cascades. Abnormalities in these mechanism are known to contribute towards hypertension. It is thus plausible that polymorphisms in the epidermal growth factor receptor gene would be associated with the development of hypertension in women with gestational diabetes.
Aim: To determine whether the …

The Chaotic Domestic: Tracing Affect In Representations Of Nation, Class, And Gender In Eighteenth-Century Laboring-Class Women’S Writing, Kelly J. Hunnings Jul 2019

The Chaotic Domestic: Tracing Affect In Representations Of Nation, Class, And Gender In Eighteenth-Century Laboring-Class Women’S Writing, Kelly J. Hunnings

English Language and Literature ETDs

My dissertation traces a term I call the “chaotic domestic” in the writing of a collection of eighteenth-century women laboring-class writers: Mary Barber, Mary Collier, Mary Leapor, Ann Yearsley, and Janet Little. The chaotic domestic in the hands of these writers is multi-layered and affect-driven, focusing as they do on issues regarding nation, class, and gender. As both a poetic trope and the seeming natural and dynamic state of the domestic sphere, the image of the domestic that this set of writers represents and defines is turbulent, unruly, and one that deals with the tangled web of local and global, …
