Development Of A Synthetic Biomarker System For Early Detection Of Myocardial Infarction, Kennedy Alexis Bietz Mar 2025

Development Of A Synthetic Biomarker System For Early Detection Of Myocardial Infarction, Kennedy Alexis Bietz

Honors Thesis

Every year, thousands of Americans suffer from the event of a heart attack, i.e., myocardial infarction (MI). Currently, the early detection of MI remains a challenge. We intend to solve the problem by constructing a synthetic biomarker system that would be able to recognize early warning signs of MI, such as cellular inflammation and oxidative stress. We have proposed two different pathology specific genetic sensors that act as artificial promoters to transcribe a peptide that can be secreted into the blood stream and eventually work its way into the urine and act as a reporter that can be detected through …


A Life Course Approach To Understanding Preserved Cognition In Late Life, Cassidy E. Doyle Mar 2025

A Life Course Approach To Understanding Preserved Cognition In Late Life, Cassidy E. Doyle

USF Tampa Graduate Theses and Dissertations

Some level of cognitive decline is generally expected with advanced age. However, a subgroup of individuals – commonly labeled as ‘SuperAgers’ – maintain youthful memory abilities into their 80s and beyond. Relatively little is known about factors across the life course related to this phenotype. This dissertation used population-based data from the Health and Retirement Study (HRS) to investigate lifestyle factors related to the most youthful cognitive trajectory in the United States and assess how their cognition fares over time. Three research questions were addressed: (1) Can samples of youthful cognitive agers be identified longitudinally in a population-based dataset? (2) …

Multicilia Dynamically Transduce Sonic Hedgehog Signaling To Regulate Choroid Plexus Functions, Suifang Mao, Michael J Holtzman, Et Al. Mar 2025

Multicilia Dynamically Transduce Sonic Hedgehog Signaling To Regulate Choroid Plexus Functions, Suifang Mao, Michael J Holtzman, Et Al.

2020-Current year OA Pubs

The choroid plexus is a major site for cerebrospinal fluid (CSF) production, characterized by a multiciliated epithelial monolayer that regulates CSF production. We demonstrate that defective choroid plexus ciliogenesis or intraflagellar transport yields neonatal hydrocephalus, at least in part due to increased water channel Aqp1 and ion transporter Atp1a2 expression. We demonstrate choroid plexus multicilia as sensory cilia, transducing both canonical and non-canonical Sonic Hedgehog (Shh) signaling. Interestingly, it is the non-canonical Shh signaling that represses Aqp1 and Atp1a2 expression by the Smoothened (Smo)/Gαi/cyclic AMP (cAMP) pathway. Choroid plexus multicilia exhibit unique ciliary ultrastructure, carrying features of both primary and …

Role Of Eye-Tracking Technology And Software Algorithms In Enhancing Adhd Detection And Diagnosis: A Systematic Literature Review, Lauren E. Perkins Mar 2025

Role Of Eye-Tracking Technology And Software Algorithms In Enhancing Adhd Detection And Diagnosis: A Systematic Literature Review, Lauren E. Perkins

Honors College Theses

This systematic literature review explores the role of eye-tracking technology and software algorithms in enhancing the detection and diagnosis of ADHD. ADHD, a neurodevelopmental disorder affecting both children and adults, is traditionally diagnosed through behavioral assessments, which may lack objectivity. Recent studies suggest that eye-tracking, specifically focusing on saccades, fixations, and blink rates, offers the potential for more accurate and objective measures of ADHD. The review examines clinical trials, observational studies, and machine learning research to assess the correlation between ADHD and eye movement patterns. Results indicate that individuals with ADHD exhibit distinct eye movement patterns, which can be quantified …

The Mediator complex facilitates interactions between transcription factors and RNA polymerase II, a process that is required for host gene transcription, including in response to viral infections. Among the many subunits in the Mediator complex, the MED25 subunit has been shown to be a target for viral activators during infection. Here we provide the molecular basis for the interaction between human respiratory syncytial virus (hRSV) nonstructural 1 protein (NS1) and the activator interaction domain (ACID) of MED25. The X-ray crystal structure of the complex revealed that NS1 straddles and binds two faces of MED25 ACID. This interaction is distinct from …

Mechanical stretch can activate long-lived changes in fibroblasts, increasing their contractility and initiating phenotypic transformations. This activation, critical to wound healing and procedures such as skin grafting, increases with mechanical stimulus for cells cultured in two-dimensional but is highly variable in cells in three-dimensional (3D) tissue. Here, we show that static mechanical stretch of cells in 3D tissues can either increase or decrease fibroblast activation depending upon recursive cell-extracellular matrix (ECM) feedback and demonstrate control of this activation through integrated in vitro and mathematical models. ECM viscoelasticity, signaling dynamics, and cell mechanics combine to yield a predictable, but nonmonotonic, relationship …


Carotid Peak Flow Velocity Variation As A Surrogate Of Aortic Peak Flow Velocity Variation In A Pediatric Population, Federico Cristiani, Juan Pablo Bouchacourt, Juan Riva, Pablo Motta Mar 2025

Carotid Peak Flow Velocity Variation As A Surrogate Of Aortic Peak Flow Velocity Variation In A Pediatric Population, Federico Cristiani, Juan Pablo Bouchacourt, Juan Riva, Pablo Motta

Faculty, Staff and Students Publications

Background: Carotid peak velocity variation (ΔVpeakCar) is an alternative to aortic peak velocity variation (ΔVpeakAo) and has been used in the pediatric population. Children's physiology and anatomy are heterogeneous throughout their growth. For this reason, the predictive value of ΔVpeakCar as a surrogate of ΔVpeakAo can vary at different ages. We hypothesize that the ability of ΔVpeakCar as a surrogate of ΔVpeakAo changes throughout childhood.

Aim: Analyze the concordance and the tracking ability of ΔVpeakCar and the ΔVpeakAo at different stages of development.

Methods: Patients from 0 to 12 years were included. Three groups were defined: under 12 months (G1), …

Rapid Laser Ablation-Based Fabrication Of High-Density Polymer Microwell Arrays For High-Throughput Cellular Studies, Desh Deepak Dixit, Kavya L Singampalli, Amit S Niyogi, Amanda Montoya, Alexandre Reuben, Peter B Lillehoj Mar 2025

Rapid Laser Ablation-Based Fabrication Of High-Density Polymer Microwell Arrays For High-Throughput Cellular Studies, Desh Deepak Dixit, Kavya L Singampalli, Amit S Niyogi, Amanda Montoya, Alexandre Reuben, Peter B Lillehoj

Faculty, Staff and Student Publications

Polymer-based microwell platforms have garnered much interest due to their usefulness in culturing and analyzing small quantities of biological cells and spheroids. Existing methods for fabricating polymer microwell arrays involve complex fabrication processes and/or are limited in their ability to create dense arrays of very small (< 50 μm in diameter) microwells. Here, we present a simple and rapid technique for fabricating high-density arrays of microwells ranging from 20 to 160 μm in diameter on a variety of polymer substrates. In this approach, a polymer surface is ablated using a CO2 laser that is rastered over a stainless steel mesh, which serves as a shadow mask. A theoretical laser-polymer interaction model was developed for predicting the microwell volume based on the substrate properties and laser settings. Microwell volumes predicted by the model were within 5.4% of fabricated microwell volumes determined experimentally. Cellulose acetate microwell arrays fabricated using this technique were used to culture Lewis lung carcinoma cells expressing ovalbumin (LLC-OVA), which were maintained for up to 72 h with a negligible (< 5%) loss in viability. As a second proof of principle demonstration, LLC-OVA cells grown in microwell arrays were co-cultured with OT-I T cells and measurements of interferon gamma (IFN-γ), a marker for T cell activation, were performed which revealed a positive correlation between LLC-OVA cell-T cell interaction time and T cell activation. These two in vitro demonstrations showcase the capability of this technique in generating polymer microwell arrays for high-throughput cellular studies, including cell growth dynamics studies and cell interaction studies. Furthermore, we envision that these platforms can be used with different cell types and for other biological applications, such as spheroid formation and single cell analysis, …
