Avian Adaptation To Thermal Gradients, Justin Wheeler Baldwin Dec 2024

Avian Adaptation To Thermal Gradients, Justin Wheeler Baldwin

Arts & Sciences Graduate Student Theses and Dissertations

Life on Earth has adapted to extremely different temperatures worldwide. However, across distant branches of the tree of life, animals in similar temperature environments often share similar phenotypic traits. Specifically, traits that bear on the ratio between an individual’s surface area (e.g. appendage length) and its volume (e.g. body size) are particularly important for temperature regulation and are codified in canonical biogeographical rules. Although these global patterns of finding larger-bodied (Bergmann’s Rule) and shorter-limbed (Allen’s Rule) animals in colder regions are widely upheld, they also show substantial variation. It remains poorly understood why some animals conform to these biogeographical rules …

Sustainable Plastics From Plastic Metabolisms: Leveraging Purple Non-Sulfur Bacteria For Polyhydroxyalkanoate Synthesis, Eric Michael Conners Dec 2024

Sustainable Plastics From Plastic Metabolisms: Leveraging Purple Non-Sulfur Bacteria For Polyhydroxyalkanoate Synthesis, Eric Michael Conners

Arts & Sciences Graduate Student Theses and Dissertations

Purple non-sulfur bacteria (PNSB) are a taxonomically diverse group of gram-negative bacteria representing some of Earth’s most metabolically versatile life, with many genera capable of switching between the four major metabolic modes – chemoheterotrophy, chemoautotrophy, photoheterotrophy, and photoautotrophy. Today, we exploit this diversity to explore fundamental questions about microbial metabolism. At the same time, many researchers are eager to use PNSB as tools for biotechnological innovations. Yet there exists a gap between fundamental biology and applied science. Part of the challenge is that we rely on a handful of model organisms – namely, members of the genera Rhodopseudomonas and Rhodobacter …

The Activity And Origin Of The Chitinases In The Gut Of The Mediterranean House Gecko, Alec John Dec 2024

The Activity And Origin Of The Chitinases In The Gut Of The Mediterranean House Gecko, Alec John

Masters Theses (Archived)

Chitin is a major component of the exoskeleton of arthropods as well as the cell wall of fungi. This amino polysaccharide polymer provides structure and protection to these organisms and represents a significant barrier to digestion of arthropod prey and fighting fungal infections. Chitinases are enzymes that break down chitin. Smaller insectivores, based upon the higher surface-to-volume ratio of their even smaller prey, ingest a large amount of chitin per unit prey item. Therefore, they represent high-likelihood opportunities to bio prospect for novel chitinases that may be effective against pathogenic fungi. Fungal infections are notoriously difficult to treat, and they …

The Imposition Of Power: Modernity And Nature In Hemingway And Mccarthy, Danielle Ball Dec 2024

The Imposition Of Power: Modernity And Nature In Hemingway And Mccarthy, Danielle Ball

Honors College Theses

This thesis focuses on the role of nature in opposition to modernity in Ernest Hemingway's “The Last Good Country” and “The End of Something” as well as Cormac McCarthy’s The Orchard Keeper. Each author places the forces of modernity, such as the logging industry or the introduction of the railroad, at odds with the untouched state of the natural world. Specifically, I emphasize the different portrayals of the natural world from each author. Hemingway’s nature is very closely tied to Romanticism, as nature is a spiritual and healing force for those who choose to commune with it. However, McCarthy portrays …

Meaning As Process And Product: Hybridizing Metamodern Hylosemiotics With Postmodern And Contemporary American Poetry, Zeke Shomler Dec 2024

Meaning As Process And Product: Hybridizing Metamodern Hylosemiotics With Postmodern And Contemporary American Poetry, Zeke Shomler

English

This thesis expands on Jason Storm’s theory of metamodern hylosemiotics by addressing contemporary American poetic strategies and their relationship to modernism and postmodernism, especially through Cole Swenson and David St. John’s definition of the “American hybrid.” In modifying Storm’s theoretical system, I offer a hybridized semiotics that locates meaning both in the information or “content” inferred through the act of reading and the related processes of interacting with the text. Through readings of poetry by John Ashbery, Terrance Hayes, Clark Coolidge, and William Stafford, I show that hybridizing semiotics is not only necessary for the consistency and viability of metamodern …

Breast cancer stem cells (CSCs) are resistant to most cancer therapeutics and contribute to tumor recurrence and metastasis. Two breast CSC-promoting transcription factors, truncated glioma-associated oncogene homolog 1 (tGLI1) and signal transducer and activator of transcription 3 (STAT3), have been reported to be frequently co-expressed in HER2-enriched breast cancer and triple-negative breast cancer (TNBC), undergo protein-protein interactions for gene regulation and activation, and functionally cooperate to promote breast CSCs. STAT3 can be activated by activated interleukin-6 receptor/glycoprotein-130 (IL-6R/GP130). Co-targeting of tGLI1 and IL-6R/GP130 has not been investigated in breast cancer or any tumor type. Here, we report that tGLI1 and …

Pmp2+ Scs Maintain The Survival And Functioning Of Large-Caliber Motor Axons, Mikolaj Kozlowski Dec 2024

Pmp2+ Scs Maintain The Survival And Functioning Of Large-Caliber Motor Axons, Mikolaj Kozlowski

Arts & Sciences Graduate Student Theses and Dissertations

Neurodegenerative diseases are characterized by selective neuronal vulnerability, a phenomenon in which a specific pathology induces the death of a particular subpopulation of neurons. For example, selective neuronal vulnerability in the peripheral nervous system results in sensory, motor, or mixed peripheral neuropathies. While the intrinsic differences between neuronal subtypes cannot fully explain the basis of selective neuronal vulnerability, it is plausible that it partially stems from neuron extrinsic mechanisms such as the malfunction of distinct Schwann cell (SC) subtypes. Recently, we identified an exciting subpopulation of myelinating SCs characterized by the expression of Adamtsl1, Cldn14, and Pmp2 (hereafter referred to …
