In Vitro Hydrogel Blood Clots Phantoms, Ethan Evans

Bioengineering Master's Theses

This thesis presents a mechanical and microstructural characterization of agarose-based hydrogels as synthetic thrombus analogs for balloon catheter testing. Agarose gels ranging from 0.25% to 1.0% (w/v) were fabricated and analyzed using dynamic shear rheometry, capillary flow porometry, and gas pycnometry. Rheological data showed a nonlinear increase in storage modulus (G′), from 110 ± 66 Pa at 0.25% agarose to 4,900 ± 1,600 Pa at 1.0%, effectively mimicking the viscoelastic spectrum of acute to chronic thrombi. Gas pycnometry measurements indicated that true density (P_true) increased modestly from 1.03 g/mL to 1.13 g/mL over the same concentration range. This …

Emotional Flooding: Examining Associations With Family Of Origin Violence And The Mediating Role Of Attentional Bias To Threat, Rachel Zukerman

Theses and Dissertations

Emotional flooding, or the experience of partner negative affect as intensely disorganizing and overwhelming, has recently emerged as an important variable in predicting maladaptive relationship behaviors, including intimate partner violence (IPV). However, not much is known about risk factors for flooding beyond qualities of the interpersonal interaction. While flooding depends on the experience of intense partner negative emotion, some individuals may vary regarding their propensities to feel flooded in a relatively stable way, and therefore may be more likely to engage in destructive relationship behaviors. Theory and research suggest that family violence negatively impacts emotional processing by increasing emotional arousal …

Testing Mediation Models Of Antisocial Behavior In The Context Of Parental Criminal Justice System Involvement, David Alfonso Tio

Theses and Dissertations

Parental criminal justice system involvement (CJSI) affects a significant portion of our children in a multitude of ways, including increasing the child’s risk for developing antisocial behaviors and, in doing so, perpetuating the intergenerational cycle of criminal offending that uniquely and unjustly afflicts marginalized communities of color and leaves behind what many have termed the ‘hidden victims’ of CJSI. This dissertation aimed to answer two research questions: 1. Does the division into two categories, the aggression, and rule breaking dimensions, provide a superior fitting model than the more commonly used unidimensional measure?; 2. Is it more accurate to model the …

Theses and Dissertations

This phenomenology examines the instructional practices of high school teachers and the changes the challenges of remote learning during the COVID-19 pandemic have wrought, with a focus on strategies to promote student engagement. The more students are engaged, the more they may see the relevance of their experiences, feel connected to their school experiences, and develop more positive attitudes and attributes, both inside and outside of the school walls (Bridgeland, Dilulio, & Morison, 2006). Six big themes emerged through qualitative analysis were instructional strategies, adaptation to online learning, teaching practices post 2020, perceptions of the teachers, teacher-student relationships, and barriers …

How Technology Overuse Is Affecting Youth’S Physical Activity Time, Amiya Prema Sikidar

Theses and Dissertations

Prior research demonstrates how time and energy dedicated to screens is negatively correlated with physical activity time (Alotaibi et al., 2020; Scaranni et al., 2023; Barot et al., 2023; Parasuraman et al., 2017). Therefore, in this research study, we aimed to investigate if time dedicated to screens is still replacing participation in physical activities or if technology has become so integrated in our lives over time that it no longer affects our physical activity time. We tested this via an online survey of 62 students (38 females, 24 males) at St. John’s University. Participants completed an internet addiction questionnaire (M=46.66, …

Health Literacy’S Relationship With Hearing Loss And Tinnitus In Marines And Sailors At An Air Base, Caton Harris

Theses and Dissertations

Health literacy is listed as an international health issue by the World Health Organization (WHO) and is one of the primary goals of Healthy People 2030 (USDHHR, 2023; WHO, 2023). Health literacy is the minimal amount of information needed to make appropriate health decisions (Nutbeam, 2017). Individuals must have adequate health literacy to sufficiently read and comprehend medical brochures and medical pamphlets and understand verbal instructions from their medical providers (Bo et al., 2014). Poor health literacy can reduce overall quality of life and access to health care. Health literacy is lower in adolescents and lower socioeconomic groups; therefore, the …

Mechanism Of Napthenic Acid Binding To Dissolved Organic Matter, Clarissa Jules

Theses and Dissertations

The oil sands in Alberta, Canada are being destroyed by oil extraction because remediation methods have proven largely ineffective. One toxic byproduct of oil extraction is a family of cyclical surfactant organic acids known as naphthenic acids (NAs). They are toxic to aquatic life, including fish, frogs, and aquatic birds. It is suspected that NAs bind to humic acid, a major organic component of soil, in dissolved organic matter in natural water, making them difficult to remove by conventional remediation methods. This problem prompts the following question: what is the binding mechanism between NAs and humic acid when dissolved in …

Protein-Metal Interactions Of A-Synuclein And Bioactive Transition Metals Via Molecular Dynamics, Gonzalo R. Vazquez

Theses and Dissertations

Parkinson’s Disease (PD) is a neurodegenerative movement disorder which has been found to target the dopaminergic neurons of the substantia nigra. It is characterized by the formation of masses known as Lewy Bodies, formed by aggregates of the intrinsically disordered protein (IDP) -synuclein (asyn). Research suggests that alpha synuclein can undergo aggregation in the presence of heavy metals, which may accumulate in the body through a variety of mechanisms. To study how metals may play a role in wildtype (WT) asyn aggregation, MD simulation of the protein was performed in the presence of bioactive transition metals including Fe2+, Fe3+, Cu+, …

An Ethnographic Survey Of Hispanic Parental Experiences With Special Education, Leila Fox Goldsmith

Theses and Dissertations

This study explored Spanish-speaking parents' involvement, perception, and experience with Committee on Special Education (CSE) meetings.

Improving The Safety Of N,N-Dimethylacetamide As A Potential Treatment For Preterm Birth Using A Vaginal Nanoformulation, Asad Mir

Theses and Dissertations

With no available treatment for preterm birth, the field of reproductive medicine has been repurposing small molecule candidates into vaginal nanoformulations as potential treatments for the condition. The commercial solvent N,N-Dimethylacetamide (DMA) has previously been shown to delay and prevent inflammation-induced preterm birth in a mouse model. A vaginal nanoformulation of DMA loaded into a self-nanoemulsifying drug delivery system (SNEEDS) was studied to see if it can also be efficacious. A side by-side histological comparison was done in the more pertinent tissues of the reproductive tract between the traditional formulation of DMA given intraperitoneally (IP) and the vaginal nanoformulation of …

Electrochemical And Conformational Patterns Of S-Glycosides And The Synthesis Of Schistosoma Mansoni Antigens, Bhavesh Rajendra Deore

Theses and Dissertations

This thesis dives into two relevant fields in carbohydrate science: reactivity and conformation. We centered our attention on S-glycosides, a common class of glycosyl donors and glycomimetics, to study the influence exerted by the structural architecture over the conformational properties about flexible bonds and the reactivity towards electrochemical activation. Studying the conformational properties of sugars is key to understanding the molecular recognition mechanisms underlying their biological functions. Moreover, a well understanding of how the molecular components affect free rotation about bonds can be valuable information to design improved glycomimetic drug candidates. On the other hand, electrosynthesis is a promising application …
