Caregivers Of A Child With Autism In South Florida: A Phenomenological Study, Marline Whigham

Dissertations

Autism spectrum disorder (ASD) is now well known and is being diagnosed more frequently than years ago. According to the Centers for Disease Control and Prevention in 2017, the combined estimated prevalence of ASD is 14.6 per 1,000 (1 in 68). Estimated prevalence among children age 8 was significantly higher among boys (23.6 per 1,000). ASD is a complicated and challenging disorder for every caregiver, health care providers, schools, and the overall community. However, caregivers of children with ASD receive little support. Little is known about what support is available for caregivers; not much research is available on how to …

Targeted Therapeutics And Novel Signaling Pathways In Non-Alcohol-Associated Fatty Liver/Steatohepatitis (Nafl/Nash), Dhriti Sinha, Nicholas R De Lay

Faculty, Staff and Student Publications

The C-terminal domain (CTD) of the major endoribonuclease RNase E not only serves as a scaffold for the central RNA decay machinery in gram-negative bacteria but also mediates coupled degradation of small regulatory RNAs (sRNAs) and their cognate target transcripts following RNA chaperone Hfq-facilitated sRNA-mRNA base pairing. Despite the crucial role of RNase E CTD in sRNA-dependent gene regulation, the contribution of particular residues within this domain in recruiting sRNAs and mRNAs upon base pairing remains unknown. We have previously shown that in Escherichia coli, the highly conserved 3'-5'-exoribonuclease polynucleotide phosphorylase (PNPase) paradoxically stabilizes sRNAs by limiting access of …

Hippo-Yap Signaling Maintains Sinoatrial Node Homeostasis, Mingjie Zheng, Rich G Li, Jia Song, Xiaolei Zhao, Li Tang, Shannon Erhardt, Wen Chen, Bao H Nguyen, Xiao Li, Min Li, Jianxin Wang, Sylvia M Evans, Vincent M Christoffels, Na Li, Jun Wang

Faculty, Staff and Student Publications

BACKGROUND: The sinoatrial node (SAN) functions as the pacemaker of the heart, initiating rhythmic heartbeats. Despite its importance, the SAN is one of the most poorly understood cardiac entities because of its small size and complex composition and function. The Hippo signaling pathway is a molecular signaling pathway fundamental to heart development and regeneration. Although abnormalities of the Hippo pathway are associated with cardiac arrhythmias in human patients, the role of this pathway in the SAN is unknown.

METHODS: We investigated key regulators of the Hippo pathway in SAN pacemaker cells by conditionally inactivating the Hippo signaling kinases

RESULTS: We …

Immunity To Poliovirus In Afghanistan: A Household Sampling Method For Serological Assessment Based On Geographical Information Systems, Amalia Mendes, Ari Whiteman, Benjamin Nygren, Brian Kaplan, Imtiaz Hussain, Sajid Bashir Soofi, Maureen Martinez, Noha H. Farag

Department of Paediatrics and Child Health

Afghanistan continues to experience challenges affecting polio eradication. Mass polio vaccination campaigns, which aim to protect children under the age of 5, are a key eradication strategy. To date, the polio program in Afghanistan has only employed facility-based seroprevalence surveys, which can be subject to sampling bias. We describe the feasibility in implementing a cross-sectional household poliovirus seroprevalence survey based on geographical information systems (GIS) in three districts. Digital maps with randomly selected predetermined starting points were provided to teams, with a total target of 1,632 households. Teams were instructed to navigate to predetermined starting points and enrol the closest …

Non-Charismatic Waterbodies And Ecosystem Disservices: Mine Pit Lakes Are Underrepresented In The Literature, Rachele Bernasconi, Mark A. Lund, Melanie L. Blanchette

Research outputs 2022 to 2026

Pit lakes are one of the greatest legacies of open-cut mining. Despite the potential hazards of these lakes, they represent newly formed ecosystems with great scientific and ecological potential. Although thousands of pit lakes occur on every inhabited continent, with more being created, the microbial ecology of pit lakes is relatively under-researched. We evaluated the current state of microbial research in pit lakes by performing a Web of Science search and creating a literature database. Study lakes were categorized according to location and water quality (pH and conductivity) which is a key community and environmental concern. Research technology employed in …

Parikh, Avishai Wizel, Daniel Davis, Armida Lefranc-Torres, Alejandro I. Rodarte-Rascon, Lauren E. Miller, Kevin S. Emerick, Mark A. Varvares, Daniel G. Deschler, William C. Faquin, Jon C. Aster, Derrick T. Lin, Bradley E. Bernstein, Yotam Drier, Sidharth V. Puram

2020-Current year OA Pubs

Salivary adenoid cystic carcinoma (ACC) is a rare, biologically unique biphasic tumor that consists of malignant myoepithelial and luminal cells. MYB and Notch signaling have been implicated in ACC pathophysiology, but in vivo descriptions of these two programs in human tumors and investigation into their active coordination remain incomplete. We utilize single-cell RNA sequencing to profile human head and neck ACC, including a comparison of primary ACC with a matched local recurrence. We define expression heterogeneity in these rare tumors, uncovering diversity in myoepithelial and luminal cell expression. We find differential expression of Notch ligands DLL1, JAG1, and JAG2 in …

Deficiency And Excess Of Groundwater Iodine And Their Health Associations, Ruoqi Ma, Mingquan Yan, Peng Han, Ting Wang, Bin Li, Shungui Zhou, T Zheng, Yandi Hu, Alistair G.L. Borthwick, C Zheng, Jinren Ni

School of Engineering, Computing and Mathematics

AbstractMore than two billion people worldwide have suffered thyroid disorders from either iodine deficiency or excess. By creating the national map of groundwater iodine throughout China, we reveal the spatial responses of diverse health risks to iodine in continental groundwater. Greater non-carcinogenic risks relevant to lower iodine more likely occur in the areas of higher altitude, while those associated with high groundwater iodine are concentrated in the areas suffered from transgressions enhanced by land over-use and intensive anthropogenic overexploitation. The potential roles of groundwater iodine species are also explored: iodide might be associated with subclinical hypothyroidism particularly in higher iodine …

Reshaping Aesthetics And Aesthetic Sensibility In A Hybrid Environment, Aleksandra Łukaszewicz, Jakub Petri

Contemporary Aesthetics (Journal Archive)

The contemporary environment in developed countries is highly urbanized and technologized. It is not only physical but also virtual, created with the use of cyber-techniques and the internet. The two layers of the environment are: the physical places, persons, objects, etc., and the virtual – electronically-emerged places, persons, and objects, etc. Therefore, it is correct to overcome the enforced conceptual dualism between what is virtual and what is physical, as proposed by Michal Ostrowicki (aka Sidey Myoo) in calling for the recognition of the hybrid status of reality, by pointing to symbiosis within the context of lived experience. This raises …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Black Americans At A Crossroads In American Politics: Electoral Participation, Protest, And Policy Change, Tenille-Rose Martin

Dissertations

This dissertation explores Black political participation in the United States. I argue there is a relationship between Black political participation and trust in government, political efficacy, group consciousness, linked fate, political knowledge, and desire to engage in social activism. This argument draws on research on political participation, group identity, and political behavior and attitudes within the Black community.

A mixed-method approach was used in the study. Data was collected from Blacks across the country via an original survey and interviews. The data analysis chapter determined some support for the theoretical framework, albeit aspects of the model were rejected. Results determined …

Interactions between ionic liquids and biomolecules have been of great interest due to the intrinsic properties of ionic liquids and the flexibility to mix and match cations and anions to create unique ionic liquids. A number of ionic liquid-biomolecule studies have focused on the interactions with proteins, including industrially relevant enzymes. One of these, laccase from Trametes versicolor, is a naturally derived enzyme used in the breakdown of phenolic compounds in a wide variety of industries, especially useful in breakdown of lignocellulosic materials. Here, a combination of experiments and molecular dynamics (MD) simulations were used to investigate the interactions …

“What Is The Environment Doing To Our Genes?”: A Pedigree Analysis Of The Possible Genetic Basis Of A Set Of Familial Clinical Disorders, Emily N. Goodman

Honors Theses

The exact contribution the environment plays in human health is unknown; however, it is estimated that 24% of the global disease burden and 23% of deaths are attributed to environmental factors (Remoundou and Koundouri 2009). With the statistics from previous studies drawing attention to the impact of the environment on humans, it makes sense why the number of clinical disorders is on the rise. Many are being impacted more frequently than in previous generations by clinical disorders. This study was conducted to investigate a personal pedigree to gain insight and analysis to determine a possible connection between the environment and …

Emotionally Unavailable: A Comparison On The Ability Of Children With Developmental Language Disorders To Interpret Emotions In Humans And Inanimate Objects, Savanna B. Gullett

Honors Theses

Developmental Language Disorder (DLD) is a neuro-developmental condition that emerges in early childhood and can persist into adulthood, manifesting as a variety of symptoms that can be significantly different in each individual. It has an estimated prevalence of 7.58% and is nearly 7 times more common in children than autism spectrum disorder (McGregor, 2020). As a population, individuals with DLD are at risk of facing significant issues in associating areas of language, including reading comprehension, problem-solving abilities, and social skills. Professionals have noticed emotional disconnect amongst individuals with DLD, leading to the proposition that those with DLD may have a …

Frequency Domain Diffuse Optics Spectroscopies For Quantitative Measurement Of Tissue Optical Properties, Sadhu Moka

USF Tampa Graduate Theses and Dissertations

Tissue oxygen saturation, blood flow and blood volume are physiological bio-markers of tissue health. Diffuse Optical Spectroscopy(DOS) and Diffuse Correlation Spectroscopy (DCS) are two complementary approaches to measure tissue oxygen saturation and blood flow respectively. Quantitative Diffuse Optical Spectroscopy (DOS) uses multi-spectral intensities of near-infrared light that have been modulated at RF frequencies to estimate static tissue optical properties and hence concentrations of oxygenated and de-oxygenated hemoglobin. Diffuse Correlation Spectroscopy estimates tissue dynamics - i.e., blood flow, by measuring temporal intensity auto-correlation function of backscattered light diffusing through the tissue. Conventionally, DCS instruments use coherent light sources with constant intensity. …

Bioactive Self-Forming Hydrogels For Biomedical Applications, Kirstene Arcuino Gultian Giddings

Theses and Dissertations

Hydrogels are soft biomaterials that feature a wide range of physical and biochemical properties. Although highly versatile, hydrogels typically require an exogeneous input (e.g., light, pH, temperature) to form, and this limits their use to conditions where a catalyst is present. The goal of this dissertation is to expand the use of catalyst-based hydrogels by developing hydrogels with independently tunable properties which gel in situ without external stimuli. This new class of hydrogels was developed by first modifying macromers with norbornene (Nor) or tetrazine (Tet) moieties. Macromers containing Nor or Tet remain liquid when dissolved, and upon mixing self-form into …

Optimal Construction Of A Functional Interaction Network From Pooled Library Crispr Fitness Screens, Veronica Gheorghe, Traver Hart

Faculty, Staff and Student Publications

BACKGROUND: Functional interaction networks, where edges connect genes likely to operate in the same biological process or pathway, can be inferred from CRISPR knockout screens in cancer cell lines. Genes with similar knockout fitness profiles across a sufficiently diverse set of cell line screens are likely to be co-functional, and these "coessentiality" networks are increasingly powerful predictors of gene function and biological modularity. While several such networks have been published, most use different algorithms for each step of the network construction process.

RESULTS: In this study, we identify an optimal measure of functional interaction and test all combinations of options …

Genetic And Small-Molecule Modulation Of Stat3 In A Mouse Model Of Crohn's Disease, Prema Robinson, Emily Magness, Kelsey Montoya, Nikita Engineer, Thomas K Eckols, Emma Rodriguez, David J Tweardy

Faculty, Staff and Student Publications

Crohn's disease (CD), is an inflammatory bowel disease that can affect any part of the gastro-intestinal tract (GI) and is associated with an increased risk of gastro-intestinal cancer. In the current study, we determined the role of genetic and small-molecule modulation of STAT3 in a mouse model of CD. STAT3 has 2 isoforms (α, β) which are expressed in most cells in a 4:1 ratio (α: β). STAT3α has pro-inflammatory and anti-apoptotic functions, while STAT3β has contrasting roles. We used an animal model of CD consisting of intrarectal administration of 2,4,6-trinitrobenzene sulfonic acid and examined the severity of CD in …

The Fate Of Early Perichondrial Cells In Developing Bones, Yuki Matsushita, Angel Ka Yan Chu, Chiaki Tsutsumi-Arai, Shion Orikasa, Mizuki Nagata, Sunny Y Wong, Joshua D Welch, Wanida Ono, Noriaki Ono

Faculty, Staff and Student Publications

In endochondral bone development, bone-forming osteoblasts and bone marrow stromal cells have dual origins in the fetal cartilage and its surrounding perichondrium. However, how early perichondrial cells distinctively contribute to developing bones remain unidentified. Here we show using in vivo cell-lineage analyses that Dlx5+ fetal perichondrial cells marked by Dlx5-creER do not generate cartilage but sustainably contribute to cortical bone and marrow stromal compartments in a manner complementary to fetal chondrocyte derivatives under the regulation of Hedgehog signaling. Postnatally, Dlx5+ fetal perichondrial cell derivatives preferentially populate the diaphyseal marrow stroma with a dormant adipocyte-biased state and are refractory to parathyroid …
