Glycopolymeric Nanoparticles Enrich Less Immunogenic Protein Corona And Improve Tumor Delivery Compared To Pegylated Nanoparticles, Kenneth Ryan Hulugalla

Electronic Theses and Dissertations

Nanoparticles (NPs) offer significant promise as drug delivery vehicles; however, their in vivo efficacy is often hindered by the formation of a protein corona (PC), which influences key physiological responses such as blood circulation time, biodistribution, cellular uptake, and intracellular localization. Understanding NP-PC interactions is crucial for optimizing NP design for biomedical applications. Traditional approaches have utilized hydrophilic polymer coatings like polyethylene glycol (PEG) to resist protein adsorption, but glycopolymer-coated nanoparticles have emerged as superior alternatives due to their biocompatibility and ability to reduce the adsorption of highly immunogenic proteins. In this study, we synthesized and characterized glycopolymer-based poly[2(diisopropylamino)ethyl methacrylate-b-poly(methacrylamidoglucopyranose) …

Breast Tissue As A Local Drug Reservoir For Anticancer Therapy In Breast Cancer, Saniia Shchinar

Electronic Theses and Dissertations

Breast cancer, particularly the estrogen receptor-positive (ER+) subtype, remains a formidable challenge in oncology. Traditional oral therapies for ER-positive breast cancer, such as selective estrogen receptor modulators (SERMs) like Tamoxifen (TAM) and Toremifene (TOR), often encounter issues related to limited bioavailability, metabolic complications, and significant systemic side effects. These side effects include the risk of blood clots, hot flashes, vaginal dryness, menstrual cycle disruptions, and uterus cancer, which can hinder long-term adherence to preventive therapy. The exploration of local drug delivery into breast tissue presents a promising alternative to tackle these challenges. In this study, we explored the feasibility of …

Delivery Of Gemcitabine, Stearoyl Gemcitabine And Paclitaxel Through Plga Nanoparticles And Its Effect On The Desmoplasia Of Pancreatic Cancer Spheroids, Rishabh Bahl

Electronic Theses and Dissertations

Pancreatic cancer is one of the deadliest cancers to treat. The primary cause for the drug resistance is the dense extracellular matrix (ECM) that surrounds the tumor and restricts blood supply. Gemcitabine (GEM) and paclitaxel (PTX) are drugs that are clinically used in the treatment of pancreatic cancer. GEM, however, is rapidly metabolized by cytidine deaminase (CDA) and eliminated from the body, and paclitaxel is a substrate for P- glycoprotein (P-gp) efflux receptors. Drug delivery using nanoparticles has been reported to help improve drug half-lives and bypass efflux receptors. This thesis aims to encapsulate PTX in PLGA nanoparticles (PTX-NP) and …

Role Of Interferon Induced Transmembrane Protein 3 (Ifitm3) And Neural Precursor Cell Expressed Developmentally Down Regulated Protein 4 (Nedd4) In Seneca Virus A (Sva) Replication, Shamiq Aftab

Electronic Theses and Dissertations

In this study, we studied the role of IFITM3 in SVA replication in vitro by silencing the endogenous IFITM3 in NCI-H1299 cells. An average of 1.94-fold increase in SVA VP2 expression and an average of 4.4-fold increase in supernatant virus titer was observed after 24h SVA isolate SD15-26 infection. We have indeed observed an increase in viral mRNA copies by an average of 5-fold in IFITM3 silenced NCI-H1299 cells at 8 hpi indicating that IFITM3 restricts SVA replication post virus attachment and entry. A positive correlation between interferon-alpha induced IFITM3 upregulation and reduced SVA replication was observed. To further confirm …

A Demonstration Of Enactivist Personality Assessment Using The Five-Factor Model, Garri Hovhannisyan

Electronic Theses and Dissertations

This dissertation seeks to extend the intellectual and existential horizon of the enactive approach by bringing forth an enactivist understanding of human cognitive life as it is lived from the perspective of personality traits. The theoretical task of this dissertation is to review existing evidence in support of the Enactivist Big-5 Theory (EB5T) of personality and its potential for bridging the phenomenological gap between minimal and human cognition. As a phenomenologically grounded theory of personality, EB5T conceptualizes individual differences not merely as differences in trait measures within a person but as differences in styles of how individuals bring forth, experience, …

The Impact Of Sitting And Crawling On The Acquisition Of Object Permanence In Infants With Motor Delays And Infants With Typical Development, Karl Jancart

Electronic Theses and Dissertations

Object permanence (OP) is the ability to understand that objects continue to exist even when they cannot be perceived. During play, infants with an understanding of OP will continue searching for toys when the toys have been obscured by other items. Searching requires movement. The theory of embodied cognition maintains that the form and function of an organism’s body influence how the organism learns; Therefore, if a child has difficulties with movement, as demonstrated by children with motor delays, they will likely have difficulty engaging in play, the modality by which children learn about their world. The current research is …

Understanding The Psychological Significance Of Astrology In Millennial Women's Lives, Rachel June Floyd

Electronic Theses and Dissertations

In North America, astrology has been experiencing a resurgence in popularity. This is immediately remarkable given that the United States and Canada are industrialized, modern societies where astrology is widely lamented as a pseudoscience. This dissertation presents a phenomenological exploration of the underlying reasons for this cultural trend, particularly among the demographic that uses it most: millennial women. Existing psychological literature on astrology is primarily dominated by correlational studies or historical analyses and lacks the depth and richness of direct experiences of individuals engaging with this phenomenon. This study sought to address this gap within psychological literature specifically, by conducting …

Changing The Face Of Reading Instruction: Do Culturally Relevant Passages Increase The Effects Of The Repeated Reading Intervention For Middle School Black Girls With Reading Difficulties (Bgrds)?, Olajumoke Edith Oshokoya

Electronic Theses and Dissertations

Research has shown that fewer studies have focused on improving the reading abilities of middle school Black girls (Morris, 2007). As BGRDs progress through K – 12 grades, they increasingly rely on basic and advanced reading skills (i.e., oral reading fluency [ORF] and comprehension) to learn. Providing BGRDs with engaging reading passages that are relevant to their prior knowledge, background, interests, and experiences, is more likely to motivate them to read, and eventually improve their reading skills (Cartledge et al., 2015). While there is a growing body of literature focused on Black students’ experiences, currently no study has explored the …

Negative Psychology Of Anti-Semitism: Fear Of The Uncategorizable, Benjamin Strosberg

Electronic Theses and Dissertations

Anti-Semitism is a pervasive global issue, particularly prominent in the United States. Studying and defining anti-Semitism prove remarkably challenging for scholars, leading to inadequate understanding and exclusion from contemporary academic discourse and social justice initiatives. In this dissertation, I made the case that anti-Semitism is hard to categorize, stemming, in part, from the difficulty in categorizing what it is to be Jewish, which seems to be multi-form (a figure of thought, a race, an ethnicity, a religion, a nation, none of the above). In thinking about the difficulty in categorization, I constellated various instances of anti-Jewish practices across historical epochs …

Difference And Alterity: On Hegel And Deleuze, Thomas Szwedska

Electronic Theses and Dissertations

This dissertation is a study in ontology. Its central question is: can we think difference without alterity and still think of difference as an essential determination of what something is? I answer that it is possible to ontologically disambiguate difference from alterity. The central thesis of my dissertation is that thinking difference without otherness not only produces meaningful differences, but if we are committed to a complete understanding of what difference is and how it functions, then it is necessary to account for this determination. Thus, I find two cases in the history of philosophy which do think difference without …

The Normative Requirement For Shared Decision Making (Sdm) In Healthcare Ethics, Margaret Nornor-Quadjie

Electronic Theses and Dissertations

Medicine and medical technology started to advance after World War II. During that period, the practice of medicine became technical. A lot began to happen in the biomedical world during the period after WWII that attracted comments, criticisms, and analyses from scholars. Perhaps, the 1947 Doctors’ Trial at the Nuremberg Tribunal and the Nuremberg Code may be said to be the defining moment for bioethics. These events eventually led to, in the United States, the passage of the National Research Act of 1974 that established the Institutional Review Board system and the National Commission for Protection of Human Subjects of …

Electronic Theses and Dissertations

A remote sensing study was performed to quantify current soil brine contamination across the historic Smackover Oil Field in south-central Arkansas, United States. The oil field was established in 1922 and was not subject to the future waste regulations created by the Arkansas Oil and Gas Commission. Brine is a waste product of oil manufacturing which contains water with high salt levels. The storage and transport of brine in the oil field created landscape scarring across the study area.

Landsat 9 multispectral digital imagery was utilized to create supervised classification maps based on earthen pits and creek scarring across the …

A Phenomenological Study Of The Perceptions Of Inclusive Preschool Education Through The Lens Of Interdisciplinary Early Childhood Educators., Brooke Noon

Electronic Theses and Dissertations

Young children with special needs have been educated in early childhood settings with typically developing peers for over 40 years. Successful educational inclusion in the least restrictive environment requires appropriate aids and supports (Individuals with Disabilities Act, 2004). Although researchers have studied many aspects of special education, little investigation has been conducted on the perspectives of dual certified interdisciplinary early childhood educator’s (IECE) perceptions on full inclusion in preschool. This study was designed to examine the connection between the perceptions of IECE teacher’s experiences as a dual certified educator in preschool. In total, 10 IECE teachers were interviewed and completed …
