Transcriptomic And Pharmacological Characterization Of A Murine Line Harboring An Antidepressant-Insensitive Serotonin Transporter, Meghan Alicia Rodriquez Jan 2021

Transcriptomic And Pharmacological Characterization Of A Murine Line Harboring An Antidepressant-Insensitive Serotonin Transporter, Meghan Alicia Rodriquez

Theses and Dissertations

Perinatal depression is a complex mood disorder often treated with Selective Serotonin Reuptake Inhibitor (SSRI) antidepressants, which block the serotonin transporter (SERT) and alter synaptic serotonin concentrations. The serotonergic system is highly plastic and serotonin regulates the growth and maturation of neurons and signaling systems from conception through end of life. Notably, interference with serotonin levels during an SSRI sensitive window (SSW) of development in humans and rodents has been linked to neurovegetative effects which increase susceptibility for the manifestation of anxiety- and depressive-like behaviors and can be persistent throughout life. We hypothesize the persistent behavioral perturbations resulting from acute …

Transcriptomic Analysis Of Young Regenerating Magnocellular Neurons (Mcns) Vs Mature Non- Regenerating Mcns, Malak Alzidaneen

Theses and Dissertations

Mature mammalian CNS neurons do not regenerate or recover following injuries. Different transcription factors have been linked to axonal growth and survival, and regulation changes in these transcription factors will affect the expression levels of genes involved in axonal regeneration. A robust collateral sprouting response within the distant terminal field of magnocellular neurons, the neurohypophysis, arising from the contralateral non-injured supraoptic neurons have been shown in response to unilateral denervation of MCNs tracts. This response peaked at age 35 days then it was followed by a complete loss of the regenerative capacity between 35 days and 125 days of age. …

Monolayer Sorption Isotherm Model For Surface Tension Of Aqueous Surfactant Solutions Containing Electrolytes And Organic Mixtures, Kaiser Ahmed Bhuiyan Jan 2021

Monolayer Sorption Isotherm Model For Surface Tension Of Aqueous Surfactant Solutions Containing Electrolytes And Organic Mixtures, Kaiser Ahmed Bhuiyan

Theses and Dissertations

The surface tensions and compositions of aqueous aerosols dictate surface-mediated processes, especially the growth of aerosol particles into cloud nuclei and interfacial chemical reactions. Surface tension is also an indirect proxy for the partitioning of organics to the surface due to enhanced organic activity, driven by a reduction in solubility. Model predictions are generally not available for most surfactant-laden multi-component aqueous solutions, despite the importance of surface tension. Our recent multi-component surface tension model uses competitive adsorption at the interface, but these results are not consistent with salting out.1 We have now applied these techniques to surfactants in pure water …


By A Thread: Adapting And Understanding The Literary Past Through Contemporary Costume, Sherry Bollero Jan 2021

By A Thread: Adapting And Understanding The Literary Past Through Contemporary Costume, Sherry Bollero

Theses and Dissertations

For over four hundred years, Shakespeare’s plays have been adapted from text to the visual realizations on the stage and later the screen. Scholarship has attended to the playscript and the performance, but it has largely neglected the position of the costume as a bridge between the literary past and contemporary adaptation. This project contends that costumes as adaptations themselves play a significant role in contemporary constructions of the literary past. In particular, the project attends to the contribution of costumes in the visualization of Shakespeare’s histories on screen. To explore this topic, the project considers several aspects. Specifically, the …

Narratological Limitations Of Telling Trauma: A Case Study Of Lorena Bobbitt And Sexual Assault, Brittney Christy Jan 2021

Narratological Limitations Of Telling Trauma: A Case Study Of Lorena Bobbitt And Sexual Assault, Brittney Christy

Theses and Dissertations

There are many barriers that women face when they tell their stories of sexual assault, namely—that they will not be believed. A number of factors hinder believability, many of them related to the broader relationship that narrative plays in our lives. Narrative expectation, cultivated by the texts we consume, shapes what we find believable or “tellable” in the words of scholar Amy Shuman. Difficult narratives are often rendered “untellable” because they contain unfamiliar patterns or because they fall outside recognizable frameworks of understanding. Sexual assault narratives are rendered untellable for many reasons, including social misunderstanding of the problem and the …
