Towards A New Role Of Mitochondrial Hydrogen Peroxide In Synaptic Function, Cliyahnelle Z. Alexander

Student Theses and Dissertations

Aerobic metabolism is known to generate damaging ROS, particularly hydrogen peroxide. Reactive oxygen species (ROS) are highly reactive molecules containing oxygen that have the potential to cause damage to cells and tissues in the body. ROS are highly reactive atoms or molecules that rapidly interact with other molecules within a cell. Intracellular accumulation can result in oxidative damage, dysfunction, and cell death. Due to the limitations of H₂O₂ (hydrogen peroxide) detectors, other impacts of ROS exposure may have been missed. HyPer7, a genetically encoded sensor, measures hydrogen peroxide emissions precisely and sensitively, even at sublethal levels, during …

Validating A New In Vivo Model To Study Als, Izabela J. Cimachowska

Student Theses and Dissertations

Buildup of oxidative stress and mitochondrial dysfunction are well known characteristics of both sporadic and hereditary amyotrophic lateral sclerosis (ALS). While both forms of the disease seem to arise from common cellular dysfunction, the genetic disease is studied to a much greater extent. Engineering novel animal models of the sporadic form of the disease is crucial for development of druggable targets to treat ALS and understand the underlying mechanisms. Interestingly, accumulation of oxidative stress by exacerbated emission of reactive oxygen species (ROS) from presynaptic mitochondria is a hallmark of both hereditary and sporadic ALS. Previous work by our laboratory showed …

The Significance Of Sonic Branding To Strategically Stimulate Consumer Behavior: Content Analysis Of Four Interviews From Jeanna Isham’S “Sound In Marketing” Podcast, Ina Beilina

Student Theses and Dissertations

Purpose:
Sonic branding is not just about composing jingles like McDonald’s “I’m Lovin’ It.” Sonic branding is an industry that strategically designs a cohesive auditory component of a brand’s corporate identity. This paper examines the psychological impact of music and sound on consumer behavior reviewing studies from the past 40 years and investigates the significance of stimulating auditory perception by infusing sound in consumer experience in the modern 2020s.

Design/methodology/approach:
Qualitative content analysis of audio media was used to test two hypotheses. Four archival oral interview recordings from Jeanna Isham’s podcast “Sound in Marketing” featuring the sonic branding experts …

Exploring Social Determinants Of Covid-19 Related Sickness And Suffering In The Bronx, Hamida Chumpa

Student Theses and Dissertations

Through a positivistic and phenomenological approach, the study examines social determinants of COVID-19 related sickness and suffering in the Bronx, New York City, New York, ZIP codes 10462, 10472, 10467, 10458, 10474, and 10464. I utilize a violence paradigm (structural and everyday violence) to describe the social determinants of risk and sickness-related suffering and deploy an assemblage framework to shed light on how these determinants create negative synergies that undermine wellbeing and render certain communities vulnerable to extreme suffering. The mixed methods include 64 surveys and eight interviews. Analysis methods include a descriptive analysis of survey results and a thematic …

Mitochondrial Distribution Of Glycine Receptors In Motor Neuron Cell Lines, Katsiaryna Milashevich

Student Theses and Dissertations

Although non-essential, glycine plays an important role in major metabolic reactions and is most known for its anti-inflammatory effects. An accumulation of contemporary research has shown that glycine is able to stabilize membrane potential using glycine receptors at the cellular level and to protect mitochondrial function directly, whether it is from inflammation, heavy metal poisoning, or ischemia-induced neuroinflammation. In this research, the existence of a hypothetical mitochondrial glycine receptor is examined. Immunofluorescence imaging was used to examine the presence of the glycine receptor subunits alpha 1 and alpha 2 in both non- differentiated and differentiated neuroblastoma cell lines. The preliminary …

Emerging Technologies In Healthcare: Analysis Of Unos Data Through Machine Learning, Reyhan Merekar

Student Theses and Dissertations

The healthcare industry is primed for a massive transformation in the coming decades due to emerging technologies such as Artificial Intelligence (AI) and Machine Learning. With a practical application to the UNOS (United Network of Organ Sharing) database, this Thesis seeks to investigate how Machine Learning and analytic methods may be used to predict one-year heart transplantation outcomes. This study also sought to improve on predictive performances from prior studies by analyzing both Donor and Recipient data. Models built with algorithms such as Stacking and Tree Boosting gave the highest performance, with AUC’s of 0.6810 and 0.6804, respectively. In this …

An Exploratory Study Of How Millennials Approach And Communicate Mental Health In The Workplace, Johanna I. Seitenbach

Student Theses and Dissertations

Depression is the leading cause of disability worldwide, affecting more than 300 million people. As more millennials take on leadership positions, it is important to understand how companies are currently addressing mental health in the workplace and compare this to how millennials approach the subject. The quantitative analysis completed through this study helped to determine what a mentally healthy workplace looks and feels like for millennials. Companies are increasingly investing in mental health initiatives for several reasons: to increase brand recognition, to improve company culture, to mitigate potential lawsuits, and to increase employee engagement and retention. This survey assessed how …

Illness And The American Workplace: Issues And Implications For Employers And Employees, Victoria R. Dolan

Student Theses and Dissertations

This project aims to identify American employee experiences and existing workplace policies and cultures surrounding illness, disability, and sick leave. This approach was taken in order to closely examine what looks to be working well for companies and workers, and what could benefit from a more human centric approach in regards to workplace policy and employee support programs. The study of employee experiences in particular represents a gap in the current scholarly literature regarding illness and illness policy in the American workplace, and more accurately represents the experiences for both employees and employers. Furthermore, it assists with distinguishing the types …
