Oxytocin, A Lover And A Fighter: Maternal Trauma Exposure And Mother-Child Coregulation, Patricia M. Pehme

Dissertations, Theses, and Capstone Projects

The placenta is responsible for regulating the fetal growth and environment in preparation for the anticipated external life. To succeed, it continuously adapts and weaves in a variety of neuroendocrine signals from the maternal organism. If a mother was exposed to trauma and her physiology sustained a change in the functioning of the immune, autonomic and/or endocrine systems, the placenta may anticipate different external environments for her children as compared to children of mothers without trauma exposure. This dissertation examined possible underlying mechanisms of psychosocial trauma transmission from one generation to the next via the placental oxytocinergic pathway. Encompassing three …

Stability Of Two-Dimensional Magnetic Skyrmions, Amel Derras-Chouk

Dissertations, Theses, and Capstone Projects

Magnetic skyrmions are whirls formed by magnetic moments in a crystal. They have attracted attention largely due to their topological protection, which provides an avenue for technology like next-generation memory storage. The idea of topologically protected solutions of a quantum field theory was originally proposed by Tony Skyrme when he developed a model to explain the stability of hadrons in particle physics. His work has extended far beyond his original intent to several areas of condensed matter physics. Here we focus on skyrmions in magnetic materials.

Skyrme's original theory modeled excitations which exist in three spatial dimensions, a requirement for …

Destination Icaic: Cosmopolitan Intellectuals, Documentary Film And The Image Of The Cuban 1960s, Gabriel Arce-Riocabo Rollins

Dissertations, Theses, and Capstone Projects

This study analyzes the interaction between foreign intellectuals and ICAIC (Instituto cubano de artes e industrias cinematográficas) in shaping the image of Cuba in the 1960s. I make the case that the idea of Revolution was a product of cosmopolitan intellectual engagement and that in this process documentary film was a privileged medium. By tracing the development of normative stories of commitment, cosmopolitanism, and aesthetic experimentation embodied both in written texts and travel essay films, I argue that such circulation destabilizes fixed ideas of Cuban, Revolutionary or Intellectual. The archive of Danish filmmaker and ICAIC collaborator Theodor Christensen as well …

A Queens Community Teacher Storytelling Project: A Qualitative Research Study Of Five Local Afro-Caribbean And Latina Public School Teachers And Community Teachers In New York City, José Alfredo Menjivar Ortéz

Dissertations, Theses, and Capstone Projects

This dissertation thesis examines the lived experiences, life stories, and storytelling of five Afro-Caribbean and Latina people, who are all local from the borough of Queens, alumni of New York City’s public schools, and since then, became their local public school teachers, classroom practitioners, and local community teachers. We refer to this specific and unique population of teachers as alumni-community teachers and to these and other similar stories as teacher life stories.

This qualitative research and study were conducted through a series of writing workshops and semi-structured interviews. The study’s main examination is preoccupied to understand how local teachers make …

Necessity, Essence And Analyticity: Toward An Analytic Essentialist Account Of Necessity, Dongwoo Kim

Dissertations, Theses, and Capstone Projects

Some truths could not have failed to hold. Such are called metaphysically necessary truths. As Michael Dummett once aptly formulated, the philosophical problem about necessity is twofold: what makes necessary truths necessarily true and how do we recognize them as such? This dissertation aims to address these questions by developing and defending a novel account of necessity, which has the following three main theses: (1) the necessity of a statement about an entity is established as a consequence of a general principle implying that if the entity is a certain way then it is necessarily that way and the fact …

A Repository Of Books By Women From The Arab World Translated To English, Nadia El Mouldi

Dissertations, Theses, and Capstone Projects

The translation of women writers from the Arab world in the West contributes to the harmful and inaccurate stereotyping of women from the region in the Global North as oppressed and silenced. In this paper, I describe the rationale and building process for “The repository of books by women from the Arab world translated to English”, a digital project built to counter this flattened image of women from the Arab world by shedding light on the books translated so far and exposing the patterns in the choice and translation of books from Arabic to English. I start by discussing the …

The Euro And Bumps In The Road: Historical Patterns Of Nonresident Holdings In Eurozone Bonds, 1980–2018, Michael H. Scarlatos

Dissertations, Theses, and Capstone Projects

A developed bond market which attracts nonresident investors both enables and reflects a host currency’s transition from domestic to international status. My analysis of historical private nonresident holdings of Eurozone portfolio debt securities spanning the euro’s 1999 creation and its subsequent 2008 crisis reveals diverging patterns.

This analysis, complemented by coefficient stability tests, discovers that the conversion of national currencies to the euro was reflected by a pickup in nonresident holdings of bonds issued by countries adopting the euro, especially those of the periphery (Portugal, Ireland, Italy and Spain) relative to the core (Germany, Austria, Belgium, Finland, France, and the …

Transcriptional Mechanisms Of Neuroprotection In Excitotoxicity Driven Neurodegeneration In C. Elegans, Zelda Z. Mendelowitz

Dissertations, Theses, and Capstone Projects

Excitotoxicity is notorious for triggering neuronal cell death in both developmental and adult-onset neurodegenerative diseases. In excitotoxicity, excessive concentrations of Glutamate in the synapse overstimulate Glutamate Receptors (GluRs) on postsynaptic neurons. While GluR mediated degenerative mechanisms remain obscure, GluR activation was surprisingly found to also have a neuroprotective effect through activation of specific transcriptional programs. To identify evolutionarily conserved transcriptional programs in neuroprotection we use a C. elegans model of excitotoxic necrosis (glt-3;nuIs5). We have identified that non-canonical activation of the transcription factor CRH-1/CREB mediates neuroprotection in our excitotoxicity model. We found the Histone Acetyl Transferase, MYS-1/KAT6, and the neuronal …

The Moral Economy Of Ordinary Belarussians And A Critical Examination And Re-Evaluation Of The 2020 Post-Electoral Uprising, Geoffrey Blank

Dissertations, Theses, and Capstone Projects

This study is three studies in one: First, a qualitative study of the moral economy of ordinary Belarussians based on E.P Thompson’s class-based economic conception of moral economy, as applied to complex socio-economic systems by Reinarman (1987). Second, a critical and broad examination and re-evaluation of the August 9, 2020 post-electoral uprising. And third, an examination of both the West’s hostility toward Belarus’ largely state-owned socially-oriented economic model (often considered market socialism) and toward President Lukashenka, and, of the West’s commitment to overthrowing President Lukashenka and Belarus’ largely state-owned socially-oriented economic model, through its sponsorship of color revolution, “democratization,” regime …

A New Pathogenic Polg Variant

Faculty, Staff and Student Publications

POLG gene mutations are the most common causes of inherited mitochondrial disorders. The enzyme produced by this gene is responsible for the replication and repair of mitochondrial DNA. To date, around 300 pathogenic variants have been described in this gene. The resulting clinical outcomes of POLG mutations are widely variable in both phenotype and severity. There is considerable overlap in the phenotype of the so-called POLG syndromes with no clear genotype-phenotype correlation. Here we describe a newly discovered pathogenic variant in the POLG gene in a 7-year-old male that died of uncontrollable refractory status epilepticus. Genetic epilepsy panel sequencing identified …

Elucidation Of Gene Essentiality And Genetic Determinants Of Intrinsic P-Aminosalicylic Acid Resistance In Mycobacterium Kansasii, Keith J. Levendosky

Dissertations, Theses, and Capstone Projects

Mycobacterium kansasii (Mk) is an opportunistic pathogen capable of causing tuberculosis-like pulmonary disease in immunocompromised individuals and those with other risk factors including chronic obstructive pulmonary disease or malignancy. Mk is frequently isolated from man-made water sources where it forms resilient biofilms, posing a health risk to these susceptible individuals. Despite its medical relevance as an environmental pathogen, and a close phylogenetic relationship with the obligate pathogen Mycobacterium tuberculosis (Mtb), few studies to date have probed the molecular biology and genetics of Mk. Here, we sought to apply a transposon (Tn) mutagenesis tool to dissect …

Analog Matters: Labels, Cassettes, And Alternative Economies In Argentina’S Independent Music Scenes, Maria Agustina Checa

Dissertations, Theses, and Capstone Projects

This dissertation is a multi-sited ethnographic study of current cassette production and circulation in Argentina. It analyzes the work of independent labels that record music available online onto cassette tapes, incorporating a variety of music styles. I examine practices of production, circulation, and exchange, and the alternative economies performed around cassettes, with particular attention to the materialities constituting these processes. Through cassettes, I conceptualize and trace "relational value," a notion to understand objects with different kinds of social agencies valued for their abilities to generate connections. Relational value is a theoretical construct that emerges from the ground-up approach to studying …

Association Between Metabolic Overweight/Obesity Phenotypes And Readmission Risk In Patients With Lung Cancer: A Retrospective Cohort Study, Hang Dong, Jiajun Zhao

Faculty, Staff and Student Publications

BACKGROUND: Increased body mass index (BMI) and metabolic abnormalities are controversial prognostic factors of lung cancer. However, the relationship between metabolic overweight/obesity phenotypes and hospital readmission in patients with lung cancer is rarely reported.

METHODS: We established a retrospective cohort using the United States (US) Nationwide Readmissions Database (NRD). We included adult patients diagnosed with lung cancer from January 1, 2018 to November 30, 2018 and excluded patients combined with other cancers, pregnancy, died during hospitalization, low body weight, and those with missing data. The cohort was observed for hospital readmission until December 31, 2018. We defined and distinguished four …

Hepatic Circadian And Differentiation Factors Control Liver Susceptibility For Fatty Liver Disease And Tumorigenesis, Samay Shivshankar, Zheng Chen, Kai Sun, Frances M Sladek, Mamoun Younes, Kristin Eckel-Mahan

Faculty, Staff and Student Publications

Hepatocellular carcinoma (HCC) is a leading cause of cancer deaths, and the most common primary liver malignancy to present in the clinic. With the exception of liver transplant, treatment options for advanced HCC are limited, but improved tumor stratification could open the door to new treatment options. Previously, we demonstrated that the circadian regulator Aryl Hydrocarbon-Like Receptor Like 1 (ARNTL, or Bmal1) and the liver-enriched nuclear factor 4 alpha (HNF4α) are robustly co-expressed in healthy liver but incompatible in the context of HCC. Faulty circadian expression of HNF4α- either by isoform switching, or loss of expression- results in an increased …

Gastrocnemius Venous Aneurysm-A Diagnostic Dilemma, Kourosh Keyhani

Faculty, Staff and Student Publications

A 63-year-old man with multiple previous orthopedic procedures in both lower extremities had presented to us for a third opinion regarding the point-specific pain in his right lateral calf. The initial diagnosis had been venous reflux at two other institutions. However, repeat imaging studies demonstrated an aneurysmal gastrocnemius vein without any other abnormalities, such as venous reflux or thrombosis. The patient had received compression stocking therapy for 6 months but had continued to experience increasing pain at night, especially when lying in bed. The patient was reexamined in the supine position, which showed a prominent bulge in the lateral calf. …

Mir-486 Is Essential For Muscle Function And Suppresses A Dystrophic Transcriptome, Michael A Lopez, Marcas M Bamman, Jeffrey J Widrick, David K Crossman, Min Xie, David Jee, Eric C Lai, Matthew S Alexander

Faculty, Staff and Student Publications

miR-486 is a muscle-enriched microRNA, or “myomiR,” that has reduced expression correlated with Duchenne muscular dystrophy (DMD). To determine the function of miR-486 in normal and dystrophin-deficient muscles and elucidate miR-486 target transcripts in skeletal muscle, we characterized mir-486 knockout mice (mir-486 KO). mir-486 KO mice developed disrupted myofiber architecture, decreased myofiber size, decreased locomotor activity, increased cardiac fibrosis, and metabolic defects were exacerbated in mir-486 KO:mdx5cv (DKO) mice. To identify direct in vivo miR-486 muscle target transcripts, we integrated RNA sequencing and chimeric miRNA eCLIP sequencing to identify key transcripts and pathways that contribute towards mir-486 …

Informed Consent For Placebo-Controlled Trials: Do Ethics And Science Conflict?, Jon E Tyson

Faculty, Staff and Student Publications

The use of a placebo has been considered the best method for controlling bias in a prospective randomized clinical trial and provides the most rigorous test of treatment efficacy for evaluating a medical therapy. Placebos commonly produce clinically important effects particularly in studies where the primary outcomes are subjective. Yet the potential beneficial or harmful effects of placebos are often not addressed in designing a clinical trial, calculating the sample size, seeking consent, or interpreting clinical trial results. In this manuscript, we use an actual study to indicate three approaches that might be considered in seeking informed consent for placebo-controlled …

Dockopathies: A Systematic Review Of The Clinical Pathologies Associated With Human Dock Pathogenic Variants, Donna M Brown

Faculty, Staff and Student Publications

The Dedicator of Cytokinesis (DOCK) family (DOCK1-11) of genes are essential mediators of cellular migration, growth, and fusion in a variety of cell types and tissues. Recent advances in whole-genome sequencing of patients with undiagnosed genetic disorders have identified several rare pathogenic variants in DOCK genes. We conducted a systematic review and performed a patient database and literature search of reported DOCK pathogenic variants that have been identified in association with clinical pathologies such as global developmental delay, immune cell dysfunction, muscle hypotonia, and muscle ataxia among other categories. We then categorized these pathogenic DOCK variants and their associated clinical …

Estimated glomerular filtration rate (eGFR) reflects kidney function. Progressive eGFR-decline can lead to kidney failure, necessitating dialysis or transplantation. Hundreds of loci from genome-wide association studies (GWAS) for eGFR help explain population cross section variability. Since the contribution of these or other loci to eGFR-decline remains largely unknown, we derived GWAS for annual eGFR-decline and meta-analyzed 62 longitudinal studies with eGFR assessed twice over time in all 343,339 individuals and in high-risk groups. We also explored different covariate adjustment. Twelve genome-wide significant independent variants for eGFR-decline unadjusted or adjusted for eGFR-baseline (11 novel, one known for this phenotype), including nine …

Addressing Patient Heterogeneity In Disease Predictive Model Development, Xu Gao, Weining Shen, Jing Ning, Ziding Feng, Jianhua Hu

Faculty, Staff and Student Publications

This paper addresses patient heterogeneity associated with prediction problems in biomedical applications. We propose a systematic hypothesis testing approach to determine the existence of patient subgroup structure and the number of subgroups in patient population if subgroups exist. A mixture of generalized linear models is considered to model the relationship between the disease outcome and patient characteristics and clinical factors, including targeted biomarker profiles. We construct a test statistic based on expectation maximization (EM) algorithm and derive its asymptotic distribution under the null hypothesis. An important computational advantage of the test is that the involved parameter estimates under the complex …

Repeatability And Reproducibility Assessment Of The Apparent Diffusion Coefficient In The Prostate: A Trial Of The Ecog-Acrin Research Group (Acrin 6701), Michael A Boss, Bradley S Snyder, Eunhee Kim, Dena Flamini, Sarah Englander, Naveen Gumpeni, Haesun Choi, Adam T Froemming, Thorsten Persigehl, Matthew S Davenport, Dariya Malyarenko, Thomas L Chenevert, Mark A Rosen

Faculty, Staff and Student Publications

Background: Uncertainty regarding the reproducibility of the apparent diffusion coefficient (ADC) hampers the use of quantitative diffusion-weighted imaging (DWI) in evaluation of the prostate with magnetic resonance imaging MRI. The quantitative imaging biomarkers alliance (QIBA) profile for quantitative DWI claims a within-subject coefficient of variation (wCV) for prostate lesion ADC of 0.17. Improved understanding of ADC reproducibility would aid the use of quantitative diffusion in prostate MRI evaluation.

Purpose: Evaluation of the repeatability (same-day) and reproducibility (multi-day) of whole-prostate and focal-lesion ADC assessment in a multi-site setting.

Study type: Prospective multi-institutional.

Subjects: Twenty-nine males, ages 53 to 80 (median 63) …

Intermediary Role Of Lung Alveolar Type 1 Cells In Epithelial Repair Upon Sendai Virus Infection, Belinda J Hernandez, Margo P Cain, Anne M Lynch, Jose R Flores, Michael J Tuvim, Jichao Chen

Faculty, Staff and Student Publications

The lung epithelium forms the first barrier against respiratory pathogens and noxious chemicals; however, little is known about how more than 90% of this barrier, made of AT1 (alveolar type 1) cells, responds to injury. Using the Sendai virus to model natural infection in mice, we find evidence that AT1 cells have an intermediary role by persisting in areas depleted of AT2 cells, upregulating IFN responsive genes, and receding from invading airway cells. Sendai virus infection mobilizes airway cells to form alveolar SOX2+ (Sry-box 2+) clusters without differentiating into AT1 or AT2 cells. Large AT2 cell-depleted areas remain covered by …

New Sedatives And Analgesic Drugs For Gastrointestinal Endoscopic Procedures, Jun Yong Bae, Jun-Won Chung, Hyun Ho Choi, Jun Kyu Lee, Byung-Wook Kim

Faculty, Staff and Student Publications

Procedural sedation has become increasingly common in endoscopy. Sedatives and analgesics induce anxiolysis and amnesia. In addition, an appropriate level of sedation is necessary for safe procedures including therapeutic endoscopy. Midazolam and propofol are the most commonly used drugs in sedative endoscopy. In recent years, the need to ascertain the safety and effectiveness of sedation has increased in practice. Therefore, new sedatives and analgesic drugs for optimal sedative endoscopy, have recently emerged. This article reviews the characteristics of sedatives and analgesics, and describes their clinical use in gastrointestinal endoscopy.
