Exploring A Gene Panel For Parkinson’S Disease In An Egyptian Cohort, Asmaa Saeed Gabr

Theses and Dissertations

Parkinson’s disease is a highly heterogeneous disorder characterized by diverse neuropathological features, clinical presentations and progression patterns. In Egypt, Parkinson’s disease incidence rates lie outside the range reported elsewhere. The genetic background to the pathogenesis of Parkinson's disease has been postulated for a long time. However, Parkinson’s disease has never been systematically investigated in Egypt. This study aimed to explore genetic variants and interactions that are associated with the familial and sporadic forms of Parkinson's disease in an Egyptian cohort. This includes examining variants in PD-related genes, exploring the role of specific genes like MAPT and adjacent genomic regions, and …


The Impact Of Sharing Economy Platforms On Tourism: Opportunities, Challenges, And Future Directions, Mehmet Bahar Feb 2024

The Impact Of Sharing Economy Platforms On Tourism: Opportunities, Challenges, And Future Directions, Mehmet Bahar

Journal of Global Hospitality and Tourism

The sharing economy is a socio-economic phenomenon where surplus goods and services, aided by technology, are shared mutually among those in need and providers, coming together to exchange these goods and services. Economic crises, environmental issues, changes in social life, and technological advancements have led to the emergence of the sharing economy as an alternative model to existing goods and services. In this regard, the tourism sector has also been affected by this change, offering new travel and holiday alternatives, competitive advantages to stakeholders, the creation of new income sources, and the establishment of a more sustainable approach. Consequently, this …

Nineteen globally diverse rice cultivars were analyzed for various chemical parameters important to malting, including germination energy, protein, apparent amylose content, and gelatinization temperatures (GT). The rice cultivars were then malted, and congress mashes were produced. Several parameters important to brewing were then assessed in the malts and worts (i.e., extract, soluble protein, free amino nitrogen (FAN), GT, etc.). The rice malts produced were saccharified to varying degrees, had high limit dextrinase activities, and contained sufficient FAN/protein concentrations. This suggests their potential to yield robust fermentations in beer styles with high adjunct inclusions without requiring additional nitrogen supplementation. Rice cultivars …


The Relationship Between Cognitive Impairment In Psychiatric Patients And Readmission Rate To An Inpatient Facility, Cherilyn Isis Schuff Feb 2024

The Relationship Between Cognitive Impairment In Psychiatric Patients And Readmission Rate To An Inpatient Facility, Cherilyn Isis Schuff

Theses and Dissertations

The primary intention of this study was to further understand the impact of assessing cognitive impairment in psychiatric patients, as a mediating factor on readmission rates. Mild cognitive dysfunction impacts a patient’s functional outcomes (Bowie & Harvey, 2006; Davis et al., 2012; Marcantonio, et al., 2001). Little information exists to guide best practices in the treatment of adults with cognitive impairment who are hospitalized for acute conditions (Davis et al., 2012). A cognitive impairment may impact patient prognosis and ability to function outside of a setting focused on stabilization. Neuropsychological testing is a valuable tool in predicting a patient’s cognitive …

Faculty, Staff and Student Publications

INTRODUCTION: Although the concept of hope is highly relevant for cancer patients, little is known about its association with cancer-relevant biomarkers. Here we examined how hope was related to diurnal cortisol and interleukin-6 (IL-6), a pro-inflammatory cytokine previously associated with tumor biology and survival in ovarian cancer. Secondly, we examined whether hope and hopelessness are distinctly associated with these biomarkers.

METHOD: Participants were 292 high-grade ovarian cancer patients who completed surveys and provided saliva samples 4x/daily for 3 days pre-surgery to assess diurnal cortisol. Blood (pre-surgery) and ascites were assessed for IL-6. Hope and hopelessness were assessed using standardized survey …

Purpose: Accurate and comprehensive segmentation of cardiac substructures is crucial for minimizing the risk of radiation-induced heart disease in lung cancer radiotherapy. We sought to develop and validate deep learning-based auto-segmentation models for cardiac substructures.

Materials and methods: Nineteen cardiac substructures (whole heart, 4 heart chambers, 6 great vessels, 4 valves, and 4 coronary arteries) in 100 patients treated for non-small cell lung cancer were manually delineated by two radiation oncologists. The valves and coronary arteries were delineated as planning risk volumes. An nnU-Net auto-segmentation model was trained, validated, and tested on this dataset with a split ratio of 75:5:20. …


Mediators Of Necroptosis: From Cell Death To Metabolic Regulation, Xiaoqin Wu, Laura E Nagy, Jérémie Gautheron Feb 2024

Mediators Of Necroptosis: From Cell Death To Metabolic Regulation, Xiaoqin Wu, Laura E Nagy, Jérémie Gautheron

Faculty, Staff and Student Publications

Necroptosis, a programmed cell death mechanism distinct from apoptosis, has garnered attention for its role in various pathological conditions. While initially recognized for its involvement in cell death, recent research has revealed that key necroptotic mediators, including receptor-interacting protein kinases (RIPKs) and mixed lineage kinase domain-like protein (MLKL), possess additional functions that go beyond inducing cell demise. These functions encompass influencing critical aspects of metabolic regulation, such as energy metabolism, glucose homeostasis, and lipid metabolism. Dysregulated necroptosis has been implicated in metabolic diseases, including obesity, diabetes, metabolic dysfunction-associated steatotic liver disease (MASLD) and alcohol-associated liver disease (ALD), contributing to chronic …

Sterile inflammation, also known as 'inflammaging', is a hallmark of tissue aging. Cellular senescence contributes to tissue aging, in part, through the secretion of proinflammatory factors collectively known as the senescence-associated secretory phenotype (SASP). The genetic variability of thioredoxin reductase 1 (TXNRD1) is associated with aging and age-associated phenotypes such as late-life survival, activity of daily living and physical performance in old age. TXNRD1's role in regulating tissue aging has been attributed to its enzymatic role in cellular redox regulation. Here, we show that TXNRD1 drives the SASP and inflammaging through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) …

Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional …

Faculty, Staff and Student Publications

Background: Predicting relapse and overall survival (OS) in early-stage non-small-cell lung cancer (NSCLC) patients remains challenging. Therefore, we hypothesized that detection of circulating tumor DNA (ctDNA) can identify patients with increased risk of relapse and that integrating radiological tumor volume measurement along with ctDNA detectability improves prediction of outcome.

Patients and methods: We analyzed 366 serial plasma samples from 85 patients who underwent surgical resections and assessed ctDNA using a next-generation sequencing liquid biopsy assay, and measured tumor volume using a computed tomography-based three-dimensional annotation.

Results: Our results showed that patients with detectable ctDNA at baseline or after treatment and …

Gamma band modulations in response to 4 language tasks at each electrode were visualized in real-time. Next, DCS was conducted for …


New Algorithmic Support For The Fundamental Theorem Of Algebra, Vitaly Zaderman Feb 2024

New Algorithmic Support For The Fundamental Theorem Of Algebra, Vitaly Zaderman

Dissertations, Theses, and Capstone Projects

Univariate polynomial root-finding is a venerated subjects of Mathematics and Computational Mathematics studied for four millenia. In 1924 Herman Weyl published a seminal root-finder and called it an algorithmic proof of the Fundamental Theorem of Algebra. Steve Smale in 1981 and Arnold Schonhage in 1982 proposed to classify such algorithmic proofs in terms of their computational complexity. This prompted extensive research in 1980s and 1990s, culminated in a divide-and-conquer polynomial root-finder by Victor Pan at ACM STOC 1995, which used a near optimal number of bit-operations. The algorithm approximates all roots of a polynomial p almost as fast as one …


The Early Late Miocene Cessation Of Deep And Intermediate Water Circulation Through The Central American Seaway, Benjamin Stanley Kwiatkowski Feb 2024

The Early Late Miocene Cessation Of Deep And Intermediate Water Circulation Through The Central American Seaway, Benjamin Stanley Kwiatkowski

Dissertations, Theses, and Capstone Projects

The state of the middle late Miocene global ocean circulations which regulated climate and affected deep ocean chemical environments were impacted by geographic changes. During the Miocene, cirum-equatorial circulations slowly decreased, which included through the seaway between the Americas called the Central American Seaway (CAS). Its shoaling and ultimate closing led to the onset of modern day oceanic circulation as characterized by the global thermohaline circulation. However, this seaway has a long hotly debated history concerning the timing of its restriction and shallowing owing in part to the shifting of tectonic plates.

The goal of this research focuses on investigating …


Fashion, Freedom, And Feminism: The Transcendent Work Of Rosa Genoni And Her "Tanagra Dress" Reimagined, Christina Trupiano Feb 2024

Fashion, Freedom, And Feminism: The Transcendent Work Of Rosa Genoni And Her "Tanagra Dress" Reimagined, Christina Trupiano

Dissertations, Theses, and Capstone Projects

The fashion industry itself is broad in scope and dependent upon numerous sub-industries to produce its garments. It is heavily dependent upon machinery of all kinds, yet unlike many industries today, it is still also largely reliant on manual labor, specifically minority women labor. This dependance upon manual labor correlates with its long history of worker exploitation and sweated labor. The concentration of exploitative labor practices in the fashion industry have made it a focal point in the ongoing struggle between workers and the downward pressure capitalism and industrialization placed on worker compensation, quality of life and job security.

Teaching In The “Home Language” Is Not Enough: Navigating Spanish Raciolinguistic Ideologies In A Dual Language Bilingual Program, Gladys Yacely Aponte

Dissertations, Theses, and Capstone Projects

This ethnographic case study examines how fourth graders in a New York City Spanish/English dual language bilingual public school navigate hegemonic language ideologies about Spanish. Drawing on the scholarship of raciolinguistic ideologies—those that position the language practices of people of color as inherently deficient (Flores & Rosa, 2015), I analyze the discourse of seven Kiskeyanx students to examine how they navigate the widespread raciolinguistic marginalization of Kiskeyanxs— a demographic that is racialized as more Black than other Spanish-speaking groups.

As a first-generation Kiskeyana-New Yorker, a bilingual teacher educator and researcher, and a former dual language bilingual public-school teacher, it …

Socially Safe On Smartphones: How Smartphone Use Reduces Social Risk Taking, Diogo Koch Alves

Dissertations, Theses, and Capstone Projects

Consumers are often faced with decisions that carry a degree of social risk, with uncertain outcomes that could impact their social standing. Examples include choosing the ideal outfit to wear to an upcoming party or selecting a gift to give to a friend. Given the prevalence of smartphones in consumer decision making, I investigate the effect of smartphone use on social risk taking. Across seven studies, I find that smartphone use, relative to the use of other devices, results in a lower propensity to make socially risky decisions. I propose that smartphone use, by increasing the salience of one’s social …

A Municipal Modernity: Women, Architecture, And Public Health In Working-Class New York, 1913–1950, Jessica Fletcher

Dissertations, Theses, and Capstone Projects

“A Municipal Modernity” is the first study to analyze the architectural history of the district health centers in New York City that women reformers and their allies founded to address poor health in working-class communities. It reveals that women’s philanthropic adaptive re-use was foundational to the architecture of the public health care in New York and led to a program of municipal district health centers. Philanthropic reformers adapted buildings in the 1910s and 1920s to provide affordable health care for low-income women and children in European immigrant and Black neighborhoods. During the New Deal, municipal officials followed the example set …

Using Leaf Spectra To Elucidate The Taxonomy And Ecology Of Living And Dried Plants, Natalia L. Quinteros Casaverde

Dissertations, Theses, and Capstone Projects

Identifying plants and understanding of changes in plant communities are crucial to the conservation and management of nature. The shortwave spectral reflectance of leaves is a promising tool for rapidly identifying species at different taxonomic ranks and predicting important plant functional traits. However, the spectral reflectance of leaves changes in response to biotic and abiotic conditions.

The aim of this dissertation is to investigate the potential of shortwave spectral reflectance to investigate (Chapter 1) how its variation affects the accuracy of methods used to predict plant taxonomies and what environmental factors most influence biophysically predicted traits, (Chapter 2) what are …

Stereospecific Cross-Coupling Reactions Of Enantioenriched Secondary Alkyltricyclohexyltin Nucleophiles, Meruyert Binayeva Feb 2024

Stereospecific Cross-Coupling Reactions Of Enantioenriched Secondary Alkyltricyclohexyltin Nucleophiles, Meruyert Binayeva

Dissertations, Theses, and Capstone Projects

Transition metal-catalyzed cross-coupling reactions have evolved into a remarkable instrument for the formation of new bonds, and have significantly impacted how we approach to access complex organic molecules. Palladium is currently one of the most popular elements for catalytic applications due to its ability to facilitate powerful carbon-carbon and carbon-heteroatom couplings. Traditional Pd-catalyzed cross-coupling reactions have primarily concentrated on C(sp2)-C(sp2) cross-couplings, yielding planar products. Considering the use of C(sp3) nucleophiles would offer a viable control of the three dimensional arrangement in molecules. Herein, the first chapter details the history and development of Pd-catalyzed Stille cross-coupling reactions. The use of configurationally …
