The Association Of Hyperhomocysteinemia (Hhcy) With Cancer Risk: An Updated Systematic Review And Meta-Analysis Of Case-Control Studies (2013-2024), Hajar Heidari

Electronic Theses & Dissertations (2024 - present)

Abstract:

Cancer continues to be one of the leading causes of morbidity and mortality globally, influenced by a complex interplay of genetic, environmental, and nutritional factors. Among these, the metabolism of homocysteine (HCY), a sulfur-containing amino acid derived from dietary methionine, has attracted growing attention due to its involvement in one-carbon metabolism and its potential link to cancer. Elevated HCY levels, a condition known as hyperhomocysteinemia (HHCY), have been shown to disrupt crucial cellular processes such as DNA methylation and promote oxidative stress (OS)—both of which contribute to genomic instability and cancer progression. Disruptions in the folate and methionine cycles, …

Intention-Setting Among Recreational Psychedelic Users: Associated Acute Effects And Changes In Well-Being, Zi Ling Fiona Low

Electronic Theses & Dissertations (2024 - present)

Psychedelic intentions play an important role in shaping acute psychedelic experiences and influencing long-term outcomes. Limited existing literature suggests that different types of intentions are linked to acute experiences and outcomes in varying ways. However, data on the types of intentions set by recreational users remain scarce, and their effects lack clarity. This study investigates intention-setting practices among recreational psychedelic users, aiming to establish a taxonomy of intentions in naturalistic use contexts and clarify user perspectives on the impact of intention-setting. We also examine how domain-specific intentions correlate with acute psychedelic effects and changes in well-being. Finally, we test a …

Integration Of Theoretical Frameworks For Problematic Exercise: Toward A Comprehensive Model Of Maladaptive And Adaptive Exercise, Christina M. Sanzari

Electronic Theses & Dissertations (2024 - present)

Exercise can promote health and well-being, and yet a proportion of individuals who exercise develop a maladaptive relationship with physical activity. Problematic exercise is often associated with significant impairment and psychological distress, yet a consensus has not been reached regarding how problematic exercise should be conceptualized. The literature distinguishes between primary exercise dependence, or excessive exercise driven by its intrinsic reinforcement, and secondary exercise dependence, or excessive exercise driven by compensatory motivations related to weight and shape concerns. However, to date, little is known about the prevalence and nature of exercise dependence in the absence of eating pathology. This incongruity …

Risk Factors For Executive Functioning Development In Preschool Children With Type 1 Diabetes, Victoria L. Ledsham

Electronic Theses & Dissertations (2024 - present)

Links between Type 1 diabetes (T1D) and decreased cognitive functioning in children are well documented, but research on executive functioning (EF) in this population is more limited. Multiple T1D-related risk factors (e.g., hypoglycemia, hyperglycemia, glycemic variability, diabetic ketoacidosis) for EF have been established throughout the literature, but their individual effects have been difficult to determine given their interrelated nature. In result, cumulative risk has been proposed as a more robust predictor of EF differences in children with T1D. Moreover, despite the importance of early T1D onset as a risk factor for EF impairment, no studies have previously investigated EF in …

Synthesis Of Small Molecules As Therapeutic Candidates, Savia Boyer

Electronic Theses & Dissertations (2024 - present)

RNA plays a critical role in many biological functions, such as normal cellular functions or disease-related processes. Regulating biological processes through RNA-based therapeutics can be employed by the reversible photoregulation of oligonucleotides. Azobenzene, a light-responsive compound that changes conformation when exposed to ultraviolet (UV) or visible light, is attached to cytidine phosphoramidite to be incorporated in a series of RNA oligonucleotides. The reversibility of the nucleoside and oligonucleotide is verified through UV melting point experiments. The modified oligonucleotide can change conformation upon light irradiation to stop reverse transcription (RT) in the presence of many different reverse transcriptase enzymes. This technique …

Transcriptome-Wide Gene Expression Analysis Of Skeletal Muscles Of Duchenne Muscular Dystrophy Mouse Models And Patients, Olivia N. Ransiear

Electronic Theses & Dissertations (2024 - present)

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive muscle degenerative disease that frequently proves fatal by age 30. It primarily affects adolescent males with symptoms appearing as early as age 6. Patients quickly lose their ability to walk due to muscle weakness and are confined to wheelchairs for the remainder of their lives. DMD is caused by a mutation in the dystrophin gene. Without dystrophin, mechanical stress, injury, or shock takes a drastic toll on muscle tissue and muscle stem cells, rendering them unable to regenerate or be repaired. This results in a rapid loss of muscular strength and muscle …

Hippocampal Insulin Exists! In Vivo Sampling Methods, Basal Concentrations, Recurrent Hypoglycemia, And Behavioral Extracellular Insulin Responses, Starlette R. Douglass

Electronic Theses & Dissertations (2024 - present)

Insulin has widespread actions within the brain, including energy homeostasis, modulation of feeding, and as a key component of memory processes. Further, brain insulin dysfunction correlates with Alzheimer's disease and other neurodegenerative disorders. To this point, measurement of hippocampal insulin has been limited. Determining in vivo hippocampal insulin levels both at a healthy baseline and after, e.g., induction of a disease state or in response to cognitive challenge, is essential to advance our understanding of both insulin's procognitive actions and to guide potential therapeutic interventions.

We first sought to establish a sampling technique for insulin within awake and moving rats …

Concurrent Parasympathetic Synchrony In Romantic Couples Exposed To Childhood Maltreatment Subtypes, Kate L. Senich

Electronic Theses & Dissertations (2024 - present)

Early responsive caregiving hones children’s physiological systems and subsequently supports social interactions (Feldman, 2007; Porges 2001; Steelman et al, 2002). Conversely, mis-attuned interactions with caregivers, such as exposure to maltreatment subtypes, might hinder social engagement capacities at both behavioral and biological levels (Kim & Cicchetti, 2004; Sheridan & McLaughlin et al., 2014). These early adverse influences endure across development and can affect behavioral and physiological interactions with romantic partners (Mayo et al., 2021; River et al., 2020; Zamir, 2022). Specifically, temporally coordinated patterns of physiological responses between partners (i.e., synchrony) are linked with important relationship behaviors, including conflict behaviors …

Impact Of The New York State Gender Recognition Act On Mental Health Outcomes Among Non-Binary Adults Served By The New York Public Mental Health System, Sahil Chaudhry

Electronic Theses & Dissertations (2024 - present)

This dissertation explores the impact of the 2021 New York State Gender Recognition Act (GRA) on mental health outcomes and service utilization among non-binary adults in the public mental health system. The GRA introduced pivotal legal reforms—including the option for an “X” gender marker and self-attestation for gender identity changes on state-issued documents—designed to affirm gender diversity and reduce structural barriers for transgender and non-binary populations. Guided by gender affirmation theory and minority stress frameworks, this study investigates how these legal shifts relate to changes in mental health service engagement and psychological well-being among non-binary individuals.

Using a difference-in-differences (DD) …

Investigation Of The Binding Mechanism Between The Supplemental And Tail Regions Of Mirna And Mrna Within Argonaute 2, Christina Ms Karadiakos

Electronic Theses & Dissertations (2024 - present)

MicroRNAs (miRNA) are a class of small non-coding RNAs that play a key role in gene silencing. miRNAs form an RNA-induced silencing complex (RISC) with the argonaute 2 (AGO2) protein in order to control gene expression through silencing messenger RNAs (mRNA). The ability for a miRNA-mRNA complex to fit into AGO2 and form the RISC is based on the location and characteristics of a central bulge, but the mechanism and interactions that lead to a functional RISC remain unknown. Using available experimental data, we modeled the miR-34 and NOTCH1 duplex inside of AGO2 with only the seed region base paired. …

Perception As Creation In Swann's Way, Ethan D. Snowball

Electronic Theses & Dissertations (2024 - present)

Marcel Proust’s Swann’s Way is written with such detail that it overwhelms both the reader’s and the character’s sensory experience. Despite all the details, each character takes their senses of the world and strings them together as coherent images and stories. Proust shows that perceptions and memories are malleable, as individuals perceive objects in a way that brings entire stories or images to their conscious experience. The way that Proust’s characters take sensory objects and create images shows that each character can consciously interpret the world around them. Social images find themselves competing with the personally constructed images of an …

Heterogeneous Being attempts to set the often-disunited aspects of the sciences and humanities in congruence and to extol and advance a hybrid creative-scientific aesthetic that moves beyond any restricted dimensions of its previously segregated fields of study. It likewise expresses the need to perpetuate that hybrid form of inquiry and representation to successfully address or convey the precarious realities of Earth’s ecological and environmental conditions. Heterogeneous Being asks readers to observe the inexhaustible proofs of our pluralized configurations with the nonhuman world, to recognize the agentic potentialities nonhuman subjects may hold both in and outside of those inhuman enmeshments, and …

Conserved A-Rich Regions In The 3’ Utr Of Zika Virus Differentially Affect Viral Gene Expression, Kristen Kaytes

Electronic Theses & Dissertations (2024 - present)

Following its discovery in 1947, Zika virus garnered little attention in the global stage until a rapidly spreading epidemic brough the virus to the global stage in 2015. Continuous advances in research have begun to further the understanding of the molecular biology of Zika virus, however much is still unknown. Much of our understanding of the virus comes from cross reference to other viruses within the same family, such as Dengue virus and West Nile virus. A commonality of these viruses is that they resemble cellular mRNAs and have a single-stranded positive-sense RNA genome that contains a 5’-cap but lacks …

Demonstration And Assessment Of Dark Field And Phase X-Ray Computed Tomography, Wadiah Hamed Allahyani

Electronic Theses & Dissertations (2024 - present)

Conventional computed tomography produces a 2D slice or 3D image from multiple conventional images to avoid overlapping structures and increase visualization of the internal features of the object. A set up, macro controls and processing for computed tomography was created for the Center for X-ray Optics for the first time, and demonstrated in this work. Adding differential phase contrast to conventional x-ray images highlights edges. Two more channels of information, dark field and integrated phase, improve the contrast and increase the signal-to-noise ratios of the image. Combining these channels with computed tomography is an important development. This work is the …

Associations Of Screen Time, Growth, And Sleep In The Upstate Kids Study, Brooke Turcotte

Electronic Theses & Dissertations (2024 - present)

In the modern digital era, children are increasingly engaging with digital media (i.e., screen time), and the health-related implications of increased screen time are not fully understood. Excessive screen time in early childhood is increasingly recognized as a potential contributing factor to adverse health outcomes, including increased body mass index (BMI) and disrupted sleep patterns. Despite American Academy of Child and Adolescent Psychiatry recommendations for limiting screen time, studies indicate that many children surpass these guidelines, leading to concerns about reduced physical activity and disrupted sleep. Sedentary behaviors associated with screen time have been linked to increased risk of obesity, …

Exploring Rna Dynamics: Insights Into Structural Modifications, Splicing Regulation, And Biological Function, Zohreh Nowzari

Electronic Theses & Dissertations (2024 - present)

The post-transcriptional regulation of RNA, particularly through alternative splicing (AS) and chemical modifications, plays a critical role in gene expression and is linked to many human diseases. This thesis investigates three interconnected aspects of RNA and DNA dynamics and their regulation, providing new insights into cellular function.

First, we examine how RNA modifications influence the structural stability of transfer RNA Phenylalanine (tRNA^Phe) in S. cerevisiae. Using temperature replica exchange molecular dynamics (T-REMD) simulations, we show that specific modifications create a network of interactions essential for maintaining tRNA’s tertiary structure. Interestingly, magnesium ions (Mg2+) can compensate for the …

Enhancing Crispr-Cas12a Activity Through Guide Rna Methylation, Hilal Dagci

Electronic Theses & Dissertations (2024 - present)

CRISPR-Cas12a is a rapidly evolving technology for improved gene editing in cells, as well as in vivo. The system, consisting of Cas12a nuclease and approximately 40-nt long guide RNA (gRNA), can efficiently recognize and cut genomic double-stranded DNA (dsDNA). Chemical modifications to the gRNA can potentially improve its dsDNA binding and enhance Cas12a-mediated nuclease activity. In this work, 5-methyl cytidine (m5C) and N6-methyl adenosine (m6A) were explored to improve the binding between gRNA and target DNA. Phosphoramidites of m5C and m6A were used to construct a library of gRNAs using solid phase RNA synthesis. Tm studies were carried out …

Multimorbidity In Adolescents: The Longitudinal Impact Of Childhood Socioeconomic Trajectories And Health Risk In Adulthood, Savitha Sambandamoorthy

Electronic Theses & Dissertations (2024 - present)

Abstract

Background:

Multimorbidity, defined as the co-occurrence of two or more health conditions (physical, mental, or both), has been thought of as a disease of the elderly, with most studies of multimorbidity focusing on adults and the elderly population. However, co-occurring (multimorbid) health conditions are common in adolescence, and it is important to understand the profiles and patterns of multimorbidity during adolescence, a critical developmental period with long-term implications. Social determinants of health, especially lower socioeconomic status (SES), are linked to higher risk of multimorbidity and poor outcomes in adulthood. However, most of the past studies that have looked at …

Phylogenetic Analysis Of Metabolic Enzymes In Hypoxic/Anoxic Conditions In Cetaceans And Cancer, Samerna A. Masih

Electronic Theses & Dissertations (2024 - present)

Cancer cells often exhibit a Warburg-like metabolism, which includes increased fatty acid synthesis and storage that help them survive in hypoxic conditions. This shift is marked by the heightened synthesis and accumulation of fatty acids, acting as a survival mechanism in low-oxygen environments (Baumann et al., 2016). Interestingly, deep-diving whales may utilize a similar metabolic pathway to produce wax esters during their prolonged dives.

Our study focused on exploring the genetic and metabolic similarities between breast cancer cells and deep-diving whales, using computational analyses to investigate lipid metabolism genes. We looked for evolutionarily conserved variations that might reveal adaptive mechanisms …

Framing Ethnicity: How Ideological Threats Shape State Policies Towards The Ethnic Chinese In Southeast Asia, Zheng Wang

Electronic Theses & Dissertations (2024 - present)

Post-colonial multiethnic societies still face significant challenges in nation-building today. Not only do countries follow different paths in dealing with ethnic diversity, but many also shift their strategies across time. State policies towards the ethnic Chinese in Southeast Asia, including accommodation, integration, marginalization, and assimilation, vary along two dimensions: the state’s discrimination towards the ethnic Chinese and the room for negotiation between the state and the ethnic Chinese in formulating these policies. Based on puzzling empirical observations on differing levels of changes in state policies towards the ethnic Chinese in Indonesia, Malaysia, and Singapore in the 1960s and 1970s, my …

Ribosome Hibernation In Mycobacterium Abscessus And Its Effect On Antibiotic Resistance, Ryan Treen

Electronic Theses & Dissertations (2024 - present)

Some NTM species, such as Mycobacterium abscessus, can cause life-threatening infections in people with underlying medical conditions. The clinical incidence of such infections is on the rise, posing an emerging threat to public health. M. abscessus is characterized by intrinsic and acquired antibiotic resistance, complicating treatment strategies. Most chemotherapeutic approaches for M. abscessus infection target the bacterial ribosome, necessitating a better understanding of the physiological processes which confer this resistance. Multiple mycobacterial species respond to zinc-limiting conditions by inducing remodeling and hibernation …

The Multifaceted Role Of Glutamate At Excitatory And Inhibitory Synapses, Maurice A. Petroccione

Electronic Theses & Dissertations (2024 - present)

Our thoughts, memories, and actions are finely controlled by the coordinated activity of neural circuits in the brain. Prior work has identified a multitude of molecular mechanisms that contribute to the generation of these higher order functions, yet we know very little about how our ability to learn and perform habitual actions change depending on how far neurotransmitters released from neurons can travel away from their point of release. This is the main focus of my work, which I carried out using a diverse toolbox and focusing on two brain regions: the hippocampus and the striatum. The hippocampus controls learning …
