Population and Public Health Science Faculty Publications

This chapter summarizes the associations between children's digital screen media use (DSMU) and their health, within the 24-h movement behavior framework (physical activities, sedentary behaviors, sleep), provides recommendations for healthy DSMU, and highlights future research directions. Key concepts include behavior displacement, combined associations, and DSMU context and content. Displacement examples include more DSMU decreasing time for healthier behaviors (e.g., physical activity or sleep) or replacing reading books and magazines with DSMU alternatives (e.g., texting, social media). How DSMU affects the relationships between various combinations of movement behaviors and children's health is largely unknown. Total DSMU is most frequently studied, but …

Whose Information Is Whose? Adult Adoptees And The Silent Struggle To Access Records, Alyssa Traina

Undergraduate Honors Theses

The United States has fifty-one different laws pertaining to adult adoptee access to their original birth certificates and adoption court records, with only fifteen states being unrestricted. These states give adult adoptees access to their documents upon request. Fifteen states are restricted, meaning they require a court order to obtain documents, which involves proving “good cause” to a judge. This requirement of “good cause” has no standard definition. The remaining twenty-one states are compromised, meaning they have complex requirements to obtain documentation. My research uses case studies of the restricted laws of California, the unrestricted laws of Louisiana, and the …

Comparisons Of Buried And Unburied Benthic Communities On Mesophotic Coral Ecosystems, Michael Mcdonough

All HCAS Student Capstones, Theses, and Dissertations

Mesophotic coral ecosystems, MCEs, are coral ecosystems found at depths between 30-150m and are divided into two zones-the upper and lower MCE. The upper MCE serves as a transitional zone between shallow water reefs (SWRs) and the lower MCE. This transition is marked by increased reliance on heterotrophy by benthic organisms. While MCEs have been of increased interest by resource managers as potential sources of resiliency for impacted benthic species, these benthic communities are understudied. Mesophotic benthic communities in close proximity of Port Everglades between 32-37m depth were surveyed using video footage recorded by a remotely operated vehicle (ROV). This …

Progerin Can Induce Dna Damage In The Absence Of Global Changes In Replication Or Cell Proliferation, Liza A. Joudeh, P. Logan Schuck, Nina M. Van, Alannah J. Dicintio, Jason A. Stewart, Alan S. Waldman

Faculty Publications

Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare genetic condition characterized by features of accelerated aging, and individuals with HGPS seldom live beyond their mid-teens. The syndrome is commonly caused by a point mutation in the LMNA gene which codes for lamin A and its splice variant lamin C, components of the nuclear lamina. The mutation causing HGPS leads to production of a truncated, farnesylated form of lamin A referred to as "progerin." Progerin is also expressed at low levels in healthy individuals and appears to play a role in normal aging. HGPS is associated with an accumulation of genomic DNA …

Effect Of Laser Textured Surface With Different Patterns On Tribological Characteristics Of Bearing Material, Paul Joshua S

Theses and Dissertations

This research work determines the wear rate and friction characteristics of bearing material under different laser textured surface conditions. Chrome steels are used in bearings since they possess high strength and wear resistance. However, when those parts are in service, failure happens due to sliding friction before the lifetime. To improve the durability of the American Iron and Steel Institute (AISI) 52100 chromium steel, in this work, the effect of laser surface texturing (LST) was analysed.

With the different pattern of circle, ellipse, groove and grid were produced on the sample surface, the wear behavior was investigated using the pin …

Species Detection And Discovery Of Zoanthidea Symbiotic With Deep-Sea Gorgonians, Saige Jost

All HCAS Student Capstones, Theses, and Dissertations

Symbiotic marine invertebrates known as Zoanthidea, from the phylum Cnidaria, live on a wide diversity of other organisms. Deep-sea corals such as Gorgonians are one of these clades of hosts. These octocorals and their Zoanthidean symbionts are challenging to collect and consequently difficult to study. However, the Evolution of Marine Symbioses Laboratory at Nova Southeastern University has obtained several samples from the Yale Peabody Museum and other museums or universities with the goal of expanding our knowledge of the diversity of Zoanthideans. Until recently, the existing taxonomic system has been based on morphological characters. A competing molecular parataxonomic system has …

BACKGROUND: Immunotherapy has improved survival for patients with advanced clear cell renal cell carcinoma (ccRCC), but resistance to therapy develops in most patients. We use cellular-resolution spatial transcriptomics in patients with immunotherapy naïve and exposed primary ccRCC tumors to better understand immunotherapy resistance.

RESULTS: Spatial molecular imaging of tumor and adjacent stroma samples from 21 tumors suggests that viable tumors following immunotherapy harbor more stromal CD8 + T cells and neutrophils than immunotherapy naïve tumors. YES1 is significantly upregulated in immunotherapy exposed tumor cells. Spatial GSEA shows that the epithelial-mesenchymal transition pathway is spatially enriched and the associated ligand-receptor transcript …

Targeting The Cholesterol Storage Enzyme Acat1/Soat1 In Brain Cells And Mouse Model: A Novel Approach To Address Aging And Apoe4-Related Neuroinflammation, Thao Nguyen Phuong Huynh Krumeich

Dartmouth College Ph.D Dissertations

Alzheimer’s Disease (AD) is a progressive neurodegenerative disease that significantly impacts nearly 7 million people in the United States. AD is characterized by the deposition of amyloid beta (Ab) plaque, tau neurofibrillary tangles (NFTs), lipids granules, and neuroinflammation. Age and apolipoprotein E4 (APOE4) are the two biggest risk factors for AD. Recent AD therapeutic development has mostly benefited the patient population with milder symptoms while causing serious side effects in APOE4 carriers, leaving the most impacted patients’ group - aged APOE4 carriers with no treatment option. With the increasing aging population, there is an urgent need for a …

This review assesses the impact of E. maxima supplementation on fish growth performance and feed utilization, considering factors like …

Differential Relationship Between Meditation Methods And Psychotic-Like And Mystical Experiences, T. Palmer, K. Kadri, E. Fakra, J. Scholl, E. Fouragnan

School of Psychology

Much work has investigated beneficial effects of mindfulness-based meditation methods, but less work has investigated potential risks and differences across meditation methods. We addressed this in a large pre-registered online survey including 613 mediators where we correlated participants’ experience with fifty meditation techniques to psychotic-like experiences (PLEs) and mystical experiences. We found a positive correlation for both PLEs and mystical experiences with techniques aiming at reducing phenomenological content (‘null-directed’, NDM) or classified as non-dual or less embodied. In contrast, methods aiming at achieving an enhanced cognitive state (CDM), also described as ‘attentional’ or strongly embodied, showed negative correlations with PLEs. …

Recurrent ovarian cancer patients, especially those resistant to platinum, lack effective curative treatments. To address this, we conducted a phase 2 clinical trial (NCT02853318) combining pembrolizumab with bevacizumab, to increase T cell infiltration into the tumor, and oral cyclophosphamide, to reduce the number of regulatory T cells. The trial accrued 40 heavily pretreated recurrent ovarian cancer patients. The primary endpoint, progression free survival, was extended to a median of 10.2 months. The secondary endpoints demonstrated an objective response rate of 47.5%, and disease control in 30% of patients for over a year while maintaining a good quality of life. We …

Liar-Dependent Gene Expression Contributes To Antimicrobial Responses In Group A, Luis Alberto Vega, Misú Sanson-Iglesias, Piyali Mukherjee, Kyle D Buchan, Gretchen Morrison, Anne E Hohlt, Anthony R Flores

Faculty, Staff and Student Publications

The ability to sense and respond to host defenses is essential for pathogen survival. Some mechanisms involve two-component systems (TCSs) that respond to host molecules, such as antimicrobial peptides (AMPs), and activate specific gene regulatory pathways to aid in survival. Alongside TCSs, bacteria coordinate cell division proteins, chaperones, cell wall sortases, and secretory translocons at discrete locations within the cytoplasmic membrane, referred to as functional membrane microdomains (FMMs). In group A Streptococcus (GAS), the FMM or “ExPortal” coordinates protein secretion, cell wall synthesis, and sensing of AMP-mediated cell envelope stress via the LiaFSR three-component system. Previously, we showed that GAS …

Telomere biology disorders (TBDs), caused by pathogenic germ line variants in telomere-related genes, present with multiorgan disease and a predisposition to cancer. Clonal hematopoiesis (CH) as a marker of cancer development and survival in TBDs is poorly understood. Here, we characterized the clonal landscape of a large cohort of 207 patients with TBD with a broad range of age and phenotype. CH occurred predominantly in symptomatic patients and in signature genes typically associated with cancers: PPM1D, POT1, TERT promoter (TERTp), U2AF1S34, and/or TP53. Chromosome 1q gain (Chr1q+) was the commonest karyotypic abnormality. Clinically, multiorgan involvement and CH in TERTp, TP53, …

Little Shop Of Patriarchy : Analyzing Constructed Vs. Essential Gender Roles, Taylor Gadsden-Deterville

Student Scholar Symposium Abstracts and Posters

Frank Oz’s Little Shop of Horrors (1986) is more than a silly kooky musical. The comedic plot dramatically dances with themes of domestic violence, poverty, and sexism. For this project, my poster will explore the expectations and representations of femininity and masculinity set up at the film's beginning versus the end. The film’s context will connect to research involving gender essentialism (innate, biological sex) and gender constructionism (socially constructed gender roles). I will analyze the roles of Seymour, Audrey, and Orin to exhibit how they discover their constructed and essential gender identities. The film represents Audrey as a ditsy hyper-feminine …

Effect Of Polyacrylamide Gel Elasticity On Collagen Type Ii Fibril Assembly, Kathryn G. Wilcox, Stephanie Kramer, Surajit Chatterjee, Adam Linscott, Sneha Suresh, Lydia Kisley, Svetlana Morozova

Faculty Scholarship

Collagen type II fibrils provide structural integrity to the articular cartilage extracellular matrix. However, the conditions that control the fibril radial size scale, distribution, and formation inside of dense networks are not well understood. We have investigated how surrounding elastic networks affect fibril formation by observing the structure and dynamics of collagen type II in model polyacrylamide gels of varying moduli. Cryogenic transmission electron microscopy (cryo-TEM) is used to image the fibril structure and is verified qualitatively with optical microscopy of fluorescently-tagged collagen within the gels. Using fluorescence correlation spectroscopy super-resolution optical fluctuation imaging (fcsSOFI), the diffusion dynamics of the …

How To Design A Program For The Poor That Is Not A Poor Program: Explaining The Political Sustainability Of The Guaranteed Income Supplement, Daniel Béland, Patrik Marier

Osgoode Hall Law Journal

Created in 1967 as a temporary program aimed at supporting low-income people during the maturation of the Canada and Quebec Pension Plans, the Guaranteed Income Supplement (GIS) has since become a permanent policy that remains a central component of Canada’s multi-layered public pension system. In this article, we explain why GIS is a popular and politically successful program that challenges the common wisdom in political science and policy analysis that “programs for the poor are poor programs.” The article shows that the success of GIS stems from its policy design (e.g., income-tested rather than means-tested benefits), the social construction of …

The Canada Disability Benefit Act And Women With Disabilities: Pursuing Disability Equality And Reducing Administrative Violence, Laverne Jacobs

Osgoode Hall Law Journal

Stakeholders have welcomed the Canadian Disability Benefits Act as an opportunity to rectify the long-standing socioeconomic disadvantage experienced by persons with disabilities. This article examines one specific form of marginalization that lies beneath the surface of the discussions surrounding poverty and persons with disabilities in Canada: It considers women with disabilities and disabled women from intersecting backgrounds, who face unique experiences of poverty that need to be addressed by any legislation aiming to eradicate income barriers for the disability community. By drawing on the theoretical frameworks of bureaucratic disentitlement, administrative violence, and disability equality, this article examines the lived realities …

BACKGROUND: Advances in our understanding of the molecular biology of meningiomas have led to significant gains in the ability to predict patient prognosis and tumor recurrence and to identify novel targets for therapeutic design. Specifically, classification of meningiomas based on DNA methylation has greatly improved our ability to risk stratify patients, however new questions have arisen in terms of the underlying impact these DNA-methylation signatures have on meningioma biology.

METHODS: This study utilizes RNA-sequencing data from 486 meningioma samples corresponding to 3 meningioma DNA-methylation groups (merlin-intact, immune-enriched, and hypermitotic), followed by in vitro experiments utilizing human meningioma cell lines.

RESULTS: …

Four main medulloblastoma (MB) molecular subtypes have been identified based on transcriptional, DNA methylation, and genetic profiles. However, it is currently not known whether 3D genome architecture differs between MB subtypes. To address this question, we performed in situ Hi-C to reconstruct the 3D genome architecture of MB subtypes. In total, we generated Hi-C and matching transcriptome data for 28 surgical specimens and Hi-C data for one patient-derived xenograft. The average resolution of the Hi-C maps was 6,833 bp. Using these data, we found that insulation scores of topologically associating domains (TADs) were effective at distinguishing MB molecular subgroups. TAD …

BACKGROUND: Mesenchymal stem cells (MSCs) derived from gestational tissues offer a promising avenue for prenatal intervention in congenital malformations although their application is hampered by concerns related to cellular plasticity and the need for invasive, high-risk surgical procedures. Here, we present naturally occurring exosomes (EXOs) isolated from amniotic fluid-derived MSCs (AF-MSCs) and their mimetic analogs (MIMs) as viable, reproducible, and stable alternatives. These nanovesicles present a minimally invasive therapeutic option, addressing the limitations of MSC-based treatments while retaining therapeutic efficacy.

METHODS: MIMs were generated from AF-MSCs by combining sequential filtration steps through filter membranes with different porosity and size exclusion …

Chemically induced proximity modalities such as targeted protein degradation (TPD) hold promise for expanding the number of proteins that can be manipulated pharmacologically. However, current TPD strategies are often limited to proteins with preexisting ligands. Molecular glues (e.g. glutarimide ligands for CUL4CRBN), offer the potential to target undruggable proteins. Yet, their rational design is largely unattainable due to the unpredictability of the ‘gain-of-function’ nature of the glue interaction upon chemical modification of ligands. We recently reported a covalent trans-labelling glue mechanism which we named ‘Template-assisted covalent modification’, where an electrophile decorated BRD4 inhibitor was effectively delivered to …
