Hidden Markov Model For Identifying Local Variants In Human Genomes Using Simulated Data, Scott Mccallum

Electronic Theses and Dissertations

Identifying adaptive mutations in genetic data is challenging due to the low frequency of occurrence of such events, and because signatures of selection are intertwined with the footprints of various other evolutionary forces that shape our genomes. Even when a larger region appears to be under selection, genomic sites that are linked to adaptive mutations have similar statistical signals, and thus can obfuscate the identification of the actual adaptive mutation. The new method described here uses a Hidden Markov Model that allows for classification of neutral, linked, and sweep (adaptive mutation) genomic sites. This model is general and can be …

Method Development Of [3 + 2] Cycloadditions Using Tertiary Amine N-Oxides And Efforts Towards The First Total Synthesis Of Chrysosporazine D, Alexander Cocolas

Electronic Theses and Dissertations

Nitrogen-containing heterocycles are ubiquitous in bioactive molecules, pharmaceutical drugs, and natural products. For this reason, finding new and efficient ways to make such compounds remains a high priority for the organic and medicinal community. Our current endeavors build upon previously established work by our group, where we generated 1,2-diamines by coupling commercially available aldehydes with trimethylamine N-oxide (TMAO) in two steps. This route proved to be effective in generating 20+ novel 1,2-diamines and imidazolidines with a demonstrated ability to undergo transformations. Using this chemistry, we have developed a diastereoselective synthesis of 50+ novel 7-azanorbornanes using tertiary amine N-oxides …

Efficient Development Of Density-Insensitive Near-Infrared Methods For In-Line Drug Content Monitoring In Continuous Powder Streams, Natasha L. Velez-Silva

Electronic Theses and Dissertations

A well-defined action plan to respond effectively to sudden changes in product demand is critical for preventing drug shortages within the pharmaceutical industry. An effective way to increase the output of a continuous manufacturing (CM) process is through flow rate adjustments. However, robust analytical methods must be in place to ensure consistent analytical performance across varying flow rates. Existing approaches for mitigating the physical effects of flow rate on Near-Infrared (NIR) measurements are often burdensome. Thus, efficient robust modeling strategies that reduce the current calibration burden and ensure model insensitivity to the physical variations in CM systems are needed. In …

Examining The Dynamic Nature Of Acceptability In A Performance Feedback Writing Intervention, Tyler J. Young

Theses - ALL

Acceptability, or the perception that an intervention is appropriate, fair, and reasonable, is a critical construct to assess when implementing interventions (Kazdin, 1981). Despite original conceptualizations of acceptability as dynamic, or changing throughout intervention implementation (Foster & Mash, 1999; Schwartz & Baer, 1991), repeated acceptability assessments have been conducted up to only 9.26% of the time in intervention research (Silva et al., 2019). Studies that have previously conducted repeated assessments did not descriptively report or analyze differences in acceptability across sessions (e.g., DuBois et al., 2016; Raggi et al., 2009). No study to date has conducted dynamic assessments of acceptability …

Assembly Of Ppsu-Oligomers, Mariam Nesterov

Student Theses and Dissertations

The development of nanostructures for delivering multiple proteins to targeted antibodies has become a promising avenue in biotechnology, driven by advancements in synthetic polymers like poly(propylene sulfone), PPSU. However, the PPSU polymer faces a major limitation - its high insolubility. To address this challenge, this study investigates whether PPSU oligomers can enhance both the solubility and stability of lysozyme, a model protein that is cost-effective and widely accessible. Using dimer, trimer, tetramer, and hexamer configurations, we analyzed the interactions between PPSU oligomer and lysozyme under varying conditions. Our results show that the dimer and trimer are water soluble (no aggregate …

Addressing Over-The-Counter Proton Pump Inhibitor Overuse: Strategies For Pharmacists To Enhance Patient Care, Brenna Hissong, Giang Nguyen, Alexander Defranco, Layla Dials, Jordyn Linfield, Haley Brown, Joshua Honaker, Samantha Mccord, Alaina Kortokrax

Pharmacy and Wellness Review

Proton pump inhibitors (PPIs) are among the most commonly prescribed and widely used medications for the treatment of gastrointestinal (GI) disorders. PPIs irreversibly inhibit the H+/K+-ATPase enzyme, effectively reducing gastric acid secretion and providing sustained relief for acid-related conditions. With the approval of over-the-counter (OTC) PPIs, the number of individuals taking these medications for prolonged periods of time without routine monitoring for the appropriateness of therapy has increased. The overuse of OTC PPIs can be attributed to a number of factors, including ease of access, perceived safety, inadequate understanding of OTC PPI treatment intervals, and a lack of awareness regarding …

Ccr5-Ligand Decorated Rilpivirine Lipid-Based Nanoparticles For Sustained Antiretroviral Responses, Milankumar Patel

Theses & Dissertations

Antiretroviral therapy (ART) is the standard remedy to improve the health-related quality of life of people living with human immunodeficiency virus (HIV). However, limited access to the viral reservoir has significantly hindered its effectiveness in fully eradicating HIV. Therefore, to improve HIV therapy, here we propose a C-C chemokine receptor type 5 (CCR5)-targeted theranostic lipid Based Nanoparticles (LBNPs) to noninvasively track and specifically deliver the antiretroviral drugs (ARVs) to the viral reservoir. A multi-modular radioactive nanoprobe was synthesized and co-encapsulated with rilpivirine (RPV, an ARV) into the LBNP to achieve a theranostic LBNP that can be tracked by positron emission …

Neurophysiological Indicators Of Neurodevelopmental Outcomes: Examining Discrimination And Habituation Among Children Born Preterm, Erin Stephanie Misato Matsuba

Dissertations - ALL

Children born preterm are at an elevated likelihood for autism (ELA) and intellectual disabilities (ID). Event-related Potentials (ERPs), such as the P1 and the Mismatch Negativity (MMN), can be used to measure underlying neurophysiology, which may aid in the identification of these important neurodevelopmental and cognitive outcomes. Specifically, enhanced P1 and MMN discrimination, measured via the difference between two alternating sounds, is associated with autism while reduced neurophysiological habituation is associated with a lower IQ. The present study sought to examine whether early auditory discrimination and habituation could differentially predict autistic traits and cognitive abilities, respectively, as well as assess …

Noise-Enhanced Network Science, Reyhaneh Abdolazimi

Dissertations - ALL

Graphs are a versatile and powerful data structure used to model complex relationships in diverse domains such as social networks, biological systems, and transportation networks. In graphs, entities are represented by nodes, and interactions or relationships between them are represented by edges. For example, in the World Wide Web, web pages are considered vertices, and if there is a link from one page to another page on the web, there will be a directed edge between those pages in its graph data structure. These structures allow us to analyze and solve important problems like community detection (identifying closely related clusters …

Modulating Liquid-Liquid Phase Separation Of Intrinsically Disordered Proteins Through Lipidation, Zhe Zhang

Dissertations - ALL

Liquid-liquid phase separation (LLPS) is a fascinating biological phenomenon that enables cells to form membraneless organelles, creating specialized compartments for orchestrating complex biochemical reactions. While significant progress has been made in deciphering the sequence determinants underlying phase separation, precisely modulating these features remains a challenge. Inspired by biology, post-translational modifications (PTMs) offer a promising approach to modulate the protein condensates formation and their properties in real-time, without altering the sequences. Despite the identification of over 300 types of PTMs, most research has predominantly focused on charge-altering modifications. The effects of non-charged PTMs, such as lipidation, on LLPS remain poorly understood. …

Predictors Of Sedimentary Organic Carbon In Seagrass Vegetated And Unvegetated Sediment In The Tamar Estuary, United Kingdom, Kathryn Pogson

The Plymouth Student Scientist

Seagrass meadows are considered significant natural carbon sinks due to their ability to store large amounts of organic carbon (C_org) in their sediments. ‘Blue carbon strategies’ aim to utilise and enhance this ability to mitigate climate change. However, assessing the C_org content and the habitat characteristics that influence this, in both seagrass vegetated and adjacent unvegetated sediments is needed to improve ‘Blue Carbon’ assessments. Currently, adjacent unvegetated sediments are excluded from Blue Carbon assessments as investigations rarely incorporate them into study design, despite evidence suggesting that they can also store significant amounts of C_org. Mean …
