Electrochemical Strategies For Microrna Quantification Leveraging Amplification And Nanomaterials: A Review, Alexander Hunt, Gymama Slaughter Jan 2025

Electrochemical Strategies For Microrna Quantification Leveraging Amplification And Nanomaterials: A Review, Alexander Hunt, Gymama Slaughter

Center for Bioelectronics Publications

MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression and have emerged as critical biomarkers in various diseases, including cancer. Their stability in bodily fluids and role as oncogenes or tumor suppressors make them attractive targets for non-invasive diagnostics. However, conventional detection methods, such as Northern blotting, RT-PCR, and microarrays, are limited by low sensitivity, lengthy protocols, and limited specificity. Electrochemical biosensors offer a promising alternative, providing high sensitivity, rapid response times, portability, and cost-effectiveness. These biosensors translate miRNA hybridization events into quantifiable electrochemical signals, often leveraging redox-active labels, mediators, or intercalators. Recent advancements in nanomaterials and signal amplification …

Weighted Family History Density Of Substance Use: Influence On Participant Substance Use Onset, Escalation, And Duration, Carleigh A. Litteral Jan 2025

Weighted Family History Density Of Substance Use: Influence On Participant Substance Use Onset, Escalation, And Duration, Carleigh A. Litteral

Theses and Dissertations--Psychology

Substance use disorders impose a staggering toll on the United States (U.S.), straining healthcare systems, destabilizing communities, and profoundly impacting both individuals and families. Approximately one in six Americans aged 12 and older had a past-year substance use disorder in 2022 (Key Substance Use, 2022), and nearly one-third of adults experience a substance use disorder in their lifetime (Wu, 2010), contributing to an economic burden exceeding $400 billion annually (National Drug Threat Assessment, 2011). Family history of substance use disorders is a key predictor of vulnerability, with individuals who have affected relatives being 2–8 times more …

The Effects Of Plx 3397 On Fentanyl Escalation In Male And Female Sprague-Dawley Rats, Jakob Shaykin Jan 2025

The Effects Of Plx 3397 On Fentanyl Escalation In Male And Female Sprague-Dawley Rats, Jakob Shaykin

Theses and Dissertations--Psychology

Purpose: A hallmark characteristic of opioid use disorder (OUD) is a persons’ ‘loss of control’, which leads to the compulsion to seek and obtain opioids, resulting in increased consumption. This phenomenon is known as ‘escalation of drug intake’. Chronic opioid use causes microglial reactivity and subsequent release of proinflammatory cytokines leading to neuroinflammation, weakening one’s executive control over drug taking and ultimately leading to greater use. Previous research in our laboratory has explored heterogeneity of fentanyl intake in extended access (6-hr) sessions and identified distinct endophenotypes of fentanyl intake. Moreover, we have observed a positive correlation between Treml1 expression …

Utilizing Evisits To Increase Access To Genetic Services For The Hearing Loss Population: A Tailored Service Delivery Model, Ansley Roberts Jan 2025

Utilizing Evisits To Increase Access To Genetic Services For The Hearing Loss Population: A Tailored Service Delivery Model, Ansley Roberts

Theses and Dissertations

Purpose: Patients referred for genetics services have specific barriers decreasing accessibility, such as communication difficulties, long wait times, and misconceptions about the utility of genetic testing. We assessed a new tailored service delivery model used by the Greenwood Genetic Center to evaluate patients referred for hearing loss to determine if this model increases access to genetics services for individuals with hearing loss. Methods: Data points such as wait times, testing plan, and diagnostic yield were compiled from patient medical records. Comparison and analysis of data was completed by visit type, in-person, virtual, and electronic visits (eVisits), between October 2023 – …

The Relationship Between Cardiac Patient Beliefs And Experiences With Insurability And Their Decisions On Whether Or Not To Pursue Genetic Testing, Julia Schoeni Jan 2025

The Relationship Between Cardiac Patient Beliefs And Experiences With Insurability And Their Decisions On Whether Or Not To Pursue Genetic Testing, Julia Schoeni

Theses and Dissertations

Since the enactment of the Genetic Information Non-Discrimination Act (GINA) in 2008, genetics providers have been incorporating conversations about GINA in pre-test counseling. There is currently limited evidence of the effects of personal or family histories of cardiomyopathy or aortopathy and associated genetic testing on patients seeking insurance policies not protected by GINA, including life, long term care, and disability insurance. This study aimed to determine whether individuals with a personal or family history of cardiomyopathy or aortopathy are having conversations about future insurability with their healthcare providers and how they perceive their ability to get these insurances when deciding …

Corals in the Persian/Arabian Gulf (PAG) are resilient to various stressors, whose levels exceed those of coral reefs globally. These corals thereby offer insight into mechanisms underlying thermal resilience, e.g., regarding the role of endosymbiotic microalgae in the family Symbiodiniaceae. Previous studies have identified the thermotolerant species Cladocopium thermophilum as broadly associated with corals in the southern PAG. However, algal-host specificity at the within-species level and the temporal stability of these associations are not well understood. Here we sampled two dominant stony corals (Porites harrisoni, n = 119 and Platygyra daedalea, n = 79) at three sites …
