Show moreA trilogy of three plays based upon the life of Florida-born author, Zora Neale Hurston, which emphasizes Hurston's unique place in American literary history. The plays, Zora, Color Struck and Weary Blues, and Tea with Zora and Marjorie are based on not only interpretations of Zora's works, letters, and conversations with people who remember her, but also the works and letters of Marjorie Kinnan Rawlings, Carl Van Vechten, Fanny Hurst, and Langston Hughes. The three plays present Hurston first as a child in Eatonville at the turn of the century, then as a young woman during the Harlem Renaissance, and finally in her full maturity. The structure of Zora and Color Struck and Weary Blues is concentrated on two of the most important days of Zora's life, which are the day of her mother's death when she was about 12 and the night of the Opportunity Award's Banquet which launched the Harlem Renaissance. The structure of Tea with Zora and Marjorie is different from the two previous plays because it relates to the period from 1942 until 1952 in the life of not only Zora Hurston but Marjorie Kinnan Rawlings, another prominent Florida writer.

Show moreLimiting undesired interactions of proteins with surfaces is a vital task for implementation of many technologies that require direct exposure to protein media. This includes sensors, single molecule spectroscopy studies, and nanoparticles that would act as vehicles for therapeutic agents or diagnostic agents. Current technology relies on the resistive properties of poly(ethylene glycol), PEG, to protein adsorption. PEG has been therefore the subject of thorough studies to decipher the mechanism involved in protein resistivity. The latter has been mainly attributed either to chain mobility, that would suffer from entropic penalty upon protein adsorption, or due to a hydration layer that prevents close encounter of proteins to the surface. Regardless of the mechanism, PEG has been reported to suffer from performance degradation in biological media due to oxidation, and its properties have been reported to differ with temperature. Given their biocompatibility, zwitterions have been proposed as a viable alternative mimicking the cell membrane. Polymeric zwitterions, the most commonly studied alternatives, result in an increase in the hydrodynamic size of particles upon grafting to surfaces. Control over size is essential as it controls the distribution of particles in the body. This work attempts to provide a different approach to nanoparticle stabilization against different aggregating factors to alleviate some of the above mentioned shortcomings of PEG and other polymers. A monomeric zwitterion siloxane was synthesized. The zwitterion siloxane covalently bonds to the oxide surface of nanoparticles without significantly changing their hydrodynamic size. The "zwitterated" particles remain stable even when challenged with high salt solutions or incubated with serum; two factors that are known to induce aggregation. The efficacy of the zwitterionic coating was compared head-to-head with a PEG coating for its ability to prevent protein adsorption to silica nanoparticles. The same siloxane coupling chemistry is employed to yield surfaces with similar coverages of both types of ligand on two geometrically different surfaces (nanoparticlesversusplanar). While both types of surface modification are highly effective in preventing protein adsorption and nanoparticle aggregation, the zwitterion provided monolayer-type coverage with minimal thickness whereas the PEG appeared to yield a more three-dimensional coating. A mechanism is proposed to explain the resistive properties of passivating ligands such as PEG and other neutral surfaces. The role of the passivating ligand is broken down to ion-coupled and ion-decoupled processes. The ion-decoupled process minimizes intermolecular interactions, whereas the ion-coupled mechanism prevents ion pairing between protein and surface charges which releases counterions and water molecules, an entropic driving force enough to overcome a disfavored enthalpy of adsorption. Finally, the synthesis of zwitterated iron oxide nanoparticles by co-precipitation of iron salts in presence of zwitterion siloxane as the stabilizing ligand is reported. This procedure yields superparamagnetic maghemite nanoparticles whose polydispersity varies as a function of the amount of zwitterion siloxane present during synthesis. The latter has the effect of changing the effective hydrodynamic radius of the particles from 5.4 nm to 35 nm. The presence of zwitterions on the surface is validated with thermogravimetric analysis and Diffuse Reflectance Infrared Fourier Transform. Magnetization versus applied field data shows the absence of coercive field and low magnetization values attributed to the decreasing particle size as well as the diamagnetic coating. The particles are tested for their possible use as MRI contrast agents. The calculated relaxation rates are low indicating that a high concentration of iron is needed for good contrast. Introduction of amine functionality for incorporation of targeting agents is achieved by the addition of aminopropyltriethoxysilane post-synthesis. The presence of the latter is verified by fluorescence spectroscopy.

Zymancer is an approximately 13 minute work for what is essentially a chamber orchestra, but with just one player to a part. Though it is written and performed as a single movement, there are three main formal sections of the piece that could be considered movements. These three sections are distinct from each other in tempi, meter, harmony, and mood. There is, however, a return of material from the first section at the end of the third.

An understanding of the role of chromatin structure and its relationship to gene regulation is critical to developing new strategies to prevent and treat diseases. We chose to investigate the anti-inflammatory response of human macrophage-like cell line (THP1) to Zymosan, in order to elucidate the regulation of chromatin. Zymosan is a component of the fungal cell wall that induces an innate immune response. After THP1 were treated with Zymosan, we hypothesized that the fungal infection would initiate an inflammatory response by altering nucleosome redistribution and/or altering chromatin structure in a time dependent manner. Based on previous results that showed rapid, widespread, transient changes in nucleosome distribution in the innate immune response, we chose to look at multiple time points at high temporal resolution: 0 (control), 20', 40', 60', 80', 100', 2h, 3h, 4h and 12h. We measured nucleosome distribution at each of these time points at hundreds of genes transcription start sites involved in the immune response. We saw the greatest changes in nucleosome positioning from 20 to 60 minutes, and it appeared that these changes were transient since they reverted back to their original after the 60-minute time point. These results support our prediction that all cells have the same nucleosome distributions during their resting states, but can be altered with the addition of an insult. In response to a stimulus, a biochemical "yawn" occurs to provide accessibility to genes needed to provide a response. The data indicates that widespread but transient changes occur to the entire genome upon response to an environmental stimulus.

Because of this association, along with political relations between the United States and Cuba, these genres have been marginalized in favor of mainstream salsa. In this thesis, I argue that casino and timba must be understood as distinct genres from an historical perspective. Additionally, I examine casino from a linguistic perspective and apply principles of linguistic relativity to create a linguistic analogy for social partner dance. By understanding casino and timba as separate from the international salsa phenomenon, they can be studied and appreciated as the unique cultural forms that they truly are.

Show moreThis dissertation considers foodways as a vital symbolic and material force in the arts of Mexico’s volatile postrevolutionary reconstruction (1920 – 1960). Although Mexican food history has stood at the forefront of a growing food studies movement, the field has been slow to appropriate image-based methodologies. Likewise, art history has been hesitant to embrace the historical performativity and materiality of foodways. This project thus seeks to fill a gap at the margins of food studies and art history, particularly at the nexus of indigeneity and urbanization. The dissertation traces the shifting relationships between art and food during a period of rampant modernization, in which the rise of modern cookery through electrical appliances and industrial foodstuffs converged and clashed with the nation’s growing nostalgia for its pre-Columbian heritage. The book focuses on three case studies of artistic production and alimentary consumption—Tina Modotti and pulque, Carlos E. González and mole poblano, and Rufino Tamayo and watermelon—that highlight the various ways in which visual renderings of food were used to frame indigenous culture as both the foundation of and a threat to the modern state. Each case study engages the convergence of racial imaginaries, artistic production, and foodways to show how conflictive attitudes toward indigenous heritage and bodies were made manifest through images of food and foodways. Therefore, this project demonstrates how seemingly innocuous images of foodstuffs and consumption became implicated in a broader visual, experiential, and commercial battle over the definition of nationalist attitudes toward indigeneity. The manuscript consists of five chapters and an appendix. Chapter 1, “Introduction,” surveys Mexican food and art histories and establishes my intersectional framework. Chapter 2, “Nursing the Nation: Pulque and the Indigenous Body in Tina Modotti’s Baby Nursing,” argues that Tina Modotti’s celebrated photograph Baby Nursing (1926) invokes the problematic consumption of pulque, an indigenous fermented beverage, as a metonym for nationalist ideologies that simultaneously celebrate and rebuke indigenous lifeways. Chapter 3, “The ‘Spirit of Mexico’: Consuming Heritage in Café de Tacuba,” demonstrates how an iconic but previously unstudied painting depicting the mythic invention of mole poblano, commissioned for Mexico City’s famous Café de Tacuba (1946), negotiates modern consumption by evoking colonial production. Chapter 4, “Mister Watermelon/Señor Sandía: Fruitful Anxieties in the Work of Rufino Tamayo,” argues that Rufino Tamayo’s still life mural Naturaleza muerta (1954), commissioned for the Sanborns department store café, mediated the state’s aggressive removal of fruteros [informal fruit vendors] by acting as both an icon of Anglophone modernity and a visual celebration of Mexican tropicalia. Chapter 5, “The Colonial in the Contemporary: On the State of Mexican Gastronomy,” presents the book’s conclusions while engaging in a critique of Mexico’s contemporary gastronomic movement and its reliance upon colonial aesthetics to veil Mexico City’s socio-economic fragmentation. The Appendix catalogues recipes for pulque, mole poblano, and watermelon-based dishes, all of which have been compiled from nineteenth- and twentieth-century cookbooks and manuscripts.

Therefore, it is not surprising that many genes involved in the circadian clock mechanism have demonstrated a regulatory role in metabolism. It has been shown that E3 ubiquitin ligases can influence metabolism as well. In initial studies, my lab created a knockout of two E3 ubiquitin ligases thought to be essential to the clock, βTRCP1/2, in a mouse model in order to study the proteasomal degradation machinery in mammals. Upon characterizing the circadian phenotype of this mouse, we noticed an unprecedented, metabolic phenotype after deletion of these vital ligases. These novel mutant mice lose over 30% of their body weight within 5 days while still maintaining an eating and drinking regime similar to wild-type mice. In this project, in vivo and sequence analysis studies aimed to look further into the causes of this phenomenon and the molecular mechanisms underlying them.

These cross sections were used to extract the delta_3 deformation length for the low-lying octupole vibration excitations in Ca-48,49 using the coupled channels analysis code fresco. Particle-core coupling in Ca-49 was studied in comparison to Ca-48 through determination of the neutron and proton deformation lengths. The total inverse kinematic proton scattering deformation lengths were evaluated for the low-lying octupole vibration excitations in Ca-48,49 to be delta_3(Ca-48, 3^-_1) = 1.0(2)fm, delta_3(Ca-49, 9/2^+_1) = 1.2(1)fm, delta_3 (Ca-49, 9/2^+_1) = 1.5(2)fm, delta_3(Ca-49, 5/2^+_1) = 1.1(1)fm. Proton and neutron deformation lengths for two of these octupole states were also determined to be delta_p(Ca-48, 3^-_1) = 0.9(1)fm, delta_p (Ca-49, 9/2^+_1) = 1.0(1)fm, delta_n(Ca-48, 3^-_1) = 1.1(3)fm, and delta_n(Ca-49, 9/2^+_1) = 1.3(3)fm. Additionally, the ratios of the neutron to proton transition matrix elements were also determined for these two states to be M_n/M_p(Ca-48, 3^-_1) = 1.7(6) and M_n/M_p(Ca-49, 9/2^+_1) = 2.0(5). Statistically, the derived values for these two nuclei are nearly identical.

It preferentially blocks a subset of Ca(2+) channels that is apparently not required for neurotransmitter release; decreases threshold for Na(+) channel activation; and slows Na(+) channel inactivation. As δ/ω-plectoxin-Pt1a enhances synaptic transmission by prolonging presynaptic release of neurotransmitter, its effects on Na(+) and Ca(2+) channels may act synergistically to sustain the terminal excitability.

The full quark model wave functions are employed to numerically calculate the form factors to all orders in (1/m[subscript c], 1/m[subscript s]). The form factors satisfy relationships expected from the heavy quark effective theory (HQET) form factors. No other semileptonic decays of Λ[subscript c] has been reported other than the decay to the ground state Λ that implies f = B(Λ[subscript c]⁺ → Λl⁺ν[subscript l])/B(Λ[subscript c]⁺ → X[subscript s]l⁺ν[subscript l]) = 1. In this work, the differential decay rates and branching fractions are calculated for transitions to the ground state and a number of excited states of Λ. The branching fraction of the semileptonic decay width to the total width of Λ[subscript c] has been calculated and compared with other theoretical estimates and experimental results. The branching fractions for Λ[subscript c] → Λ*l⁺ν[subscript l] → Σπl⁺ν[subscript l] and Λ[subscript c] → Λ*l⁺ν[subscript l] → NǨl⁺ν[subscript l] are also calculated. Apart from decays to the ground state Λ(1115), it is found that decays through the Λ(1405) provide a significant portion of the branching fraction Λ[subscript c] → X[subscript s]lν[subscript l]. There are various conjectures on the structure of the Λ(1405) while we treated it as a three quark state. A new estimate for f = B(Λ[subscript c]⁺ → Λl⁺ν[subscript l] is obtained.

Show moreThe recent breakthrough in the discovery of Weyl fermions in monopnictide semimetals provides opportunities to explore the exotic properties of relativistic fermions in condensed matter. The chiral anomaly-induced negative magnetoresistance and π Berry phase are two fundamental transport properties associated with the topological characteristics of Weyl semimetals. Since monopnictide semimetals are multiple-band systems, resolving clear Berry phase for each Fermi pocket remains a challenge. Here we report the determination of Berry phases of multiple Fermi pockets of Weyl semimetal TaP through high field quantum transport measurements. We show our TaP single crystal has the signatures of a Weyl state, including light effective quasiparticle masses, ultrahigh carrier mobility, as well as negative longitudinal magnetoresistance. Furthermore, we have generalized the Lifshitz-Kosevich formula for multiple-band Shubnikov-de Haas (SdH) oscillations and extracted the Berry phases of π for multiple Fermi pockets in TaP through the direct fits of the modified LK formula to the SdH oscillations. In high fields, we also probed signatures of Zeeman splitting, from which the Landé g-factor is extracted.

Show moreA critical consideration in the process of de novo protein architecture design and protein evolution is the folding pathway and behavior a protein undertakes in transitioning to its functional tertiary structure. Of particular interest is a cryptic element within protein primary structure that enables an efficient folding pathway, and is postulated to be a heritable element in the evolution of protein architecture, the "folding nucleus" (FN). However, almost nothing is known regarding how the FN changes as simpler peptide motifs join to form more complex polypeptides. To this effect, the structure and folding properties of foldable intermediates along the evolutionary trajectory of the β-trefoil protein type were tested. This study specifically used and compared data from Symfoil-4T (an engineered β-trefoil protein) to several mutants to show that the FN is acquired during gene fusion events, incorporating novel turn structure generated by gene fusion. Furthermore, the FN of β-trefoils are adjusted by circular permutation in response to destabilizing functional mutations to allow the survival of FN (which is made possible by the intrinsic C3 cyclic symmetry of β-trefoil architecture) identifying a selective advantage that helps explain extant cyclic structural symmetry in the proteome.

Show moreEndogenous circadian oscillators orchestrate rhythms at the cellular, physiological, and behavioral levels across species to coordinate activity, for example, sleep/wake cycles, metabolism, and learning and memory, with predictable environmental cycles. The 21st century has seen a dramatic rise in the incidence of circadian and sleep disorders with globalization, technological advances, and the use of personal electronics. The circadian clock modulates alcohol- and drug-induced behaviors with circadian misalignment contributing to increased substance use and abuse. Invertebrate models, such as , have proven invaluable for the identification of genetic and molecular mechanisms underlying highly conserved processes including the circadian clock, drug tolerance, and reward systems. In this review, we highlight the contributions of as a model system for understanding the bidirectional interactions between the circadian system and the drugs of abuse, alcohol and cocaine, and illustrate the highly conserved nature of these interactions between and mammalian systems. Research in provides mechanistic insights into the corresponding behaviors in higher organisms and can be used as a guide for targeted inquiries in mammals.

- Picture Superiority Effect on Encoding and Reminding
- Abstract/Description
-
Recent literature has demonstrated that if someone studies one list of word pairs followed by another list of word pairs in which the second half of some of the pairs have changed (e.g., they saw “knee-bone” on the first list and “knee-bend” on the second list), this change can remind them of the pair’s presence on the original list and improve memory performance for both of the pairs. Previously, this kind of design would lead researchers to observe interference, which would cause memory...
Show moreRecent literature has demonstrated that if someone studies one list of word pairs followed by another list of word pairs in which the second half of some of the pairs have changed (e.g., they saw “knee-bone” on the first list and “knee-bend” on the second list), this change can remind them of the pair’s presence on the original list and improve memory performance for both of the pairs. Previously, this kind of design would lead researchers to observe interference, which would cause memory performance to suffer; the discovery of the memory enhancing effects of reminders inspired further research to understand how their underlying mechanisms and what makes them more likely to occur. The presented research examines whether picture-word pairs will trigger more remindings than word-word pairs on the presumption that the picture superiority effect will play an important role. The results indicate that participants did experience more remindings for the picture-word pairs than for the word-word pairs and that better memory performance for picture-word pairs is due to a combination of this effect and an encoding effect.
