Characterizing The Heterogeneity Of Adult-Onset Leukoencephalopathy With Axonal Spheroids: A Digital Spatial Profiling Study, Peter Liu

Undergraduate Student Research Internships Conference

Adult-onset leukoencephalopathy with axonal spheroids (ALAS) is a group of hereditary, progressive, neurodegenerative disorders involving primarily the central nervous system white matter (WM). ALAS is characterized by patchy, asymmetrical myelin loss and axonal destruction in the WM, predominantly involving the frontoparietal regions. However, the asymmetrical and heterogenous involvement of different brain regions remains poorly characterized.

In this study, digital spatial profiling was performed to investigate the region-specific expressions of 60 proteins. Conventional immunohistochemistry methods was used validate intrepretation of probes. Using a high-plex and high-throughput method, we provide evidence of regional heterogeneity in ALAS, particularly involving key markers of microglia …

Preventing Transmission Of Covid 19 In Hvac Duct Systems: Implementations Of Hvac System Design Upgrade, Jacob S. Lopez, Adama Barro

Publications and Research

The recent pandemic outbreak has triggered a global alarm to increase efforts on finding the best methods to mitigate contagious viral pathogens. This project is a continuation of our mission to study engineering guidelines needed to implement upgrades to HVAC Systems in order to deter airborne pathogens such as the covid-19 virus. In our previous projects we researched how covid-19 can possibly flow through the ambient air inside of restaurants, office spaces, and locomotive train cabins. As we continued our research, we were able to find some solutions that will be best used to deactivate and prevent the virus from …

Understanding Of Aerosol Transmission Of Covid 19 In Indoor Environment - Part 2: Approaches To Mitigation, Adama Barro, Cathal O'Toole, Jacob S. Lopez, Matthew Quinones, Sherene Moore

Publications and Research

The challenge we face in implementing solutions for new HVAC ventilation and filtration design, is to effectively improve air quality for virus mitigation without losing performance efficiency. The purpose of this improvement is to decontaminate the occupied enclosed areas, reducing the transmission of the corona virus aerosol transmission. Our research seeks reliable approaches to mitigate the further spread of aerosol transmission in indoor spaces. The methodology is to examine innovative HVAC engineering solutions that combat epidemiological problems of Covid-19 for the post-pandemic era, by researching scholarly articles and ASHRAE journals. We are achieving the goal of finding highly efficient resolutions …

Influence Of Myelin-Associated Glycoprotein On Axon Subtype Specific Sheath Targeting, Nazmus Sakib Khan

Ramaley Celebration

During the development of the Central Nervous System, oligodendrocytes wrap axons with myelin, which is necessary for rapid, efficient nerve impulse propagation. For reasons unknown, oligodendrocytes direct myelin to certain subtypes of axons, leaving others incompletely myelinated, or even totally unmyelinated. Previous studies demonstrated mice harboring Mag mutations showed improper sheath targeting of myelin to axons indicating that MAG is a possible facilitator of axon-glia communication.

In the present study, we tested the hypothesis that loss of mag decreases the proportion of myelin directed towards specific axon subtypes. To test this, we perturbed Mag function in zebrafish embryos using knockdown …

Impact Of Acute Exercise On Micrornas Related To Concussion Symptoms, Emily Work

UNO Student Research and Creative Activity Fair

Impact of acute exercise on microRNAs related to concussion symptoms

Concussions, or traumatic brain injury (TBI), are a serious medical problem affecting approximately 1.7 million people in the United States each year. Current tools for analysis of concussion include the Glasgow Coma Scale, SCAT5, computerized topography (CT) and magnetic resonance imaging (MRI), however, these tools are typically not indicative of the range and severity of symptoms a patient may experience. Recent studies have explored the use of microRNAs as a biomarker for TBI severity in patients who have already experienced a TBI. We seek to investigate the microRNA levels in …

Primary Aortic Valve Replacement In Adults From Age 45 To 65 And How Their Survivability, Post Replacement, May Be Affected By Opting For A Bioprosthetic Or Mechanical Valve., Chandler Hutchinson

Capstone Showcase

Abstract:

Introduction: Aortic valve replacement in middle-aged adults is a procedure done when the aortic valve becomes so incompetent, that replacement is the only viable option for the patient. A bioprosthetic or a mechanical valve is then chosen and replaces the patients’ native aortic valve. For these adults, this procedure is life-extending and the only option for prolonged survival. This paper will address whether a bioprosthetic or mechanical valve would be the better option for prolonging a middle-aged patients’ life.

Methods: A literature search was completed in November of 2019 using PubMed and Google Scholar. Seven articles were chosen based …

The Efficacy Of Mirnas As A Diagnostic Tool For Endometriosis, Maura Franey

Capstone Showcase

Abstract

Introduction: Endometriosis is a chronic inflammatory gynecological condition. Laparoscopic abdominopelvic exploration is the gold standard of diagnosis, but is not performed until patients experience severe symptoms. This review analyzes the levels of circulating micro-RNAs (miRNAs) (I) for diagnosis of endometriosis (O) in women diagnosed with endometriosis (P) compared to laparoscopic exploration (C).

Methods: A literature search was conducted through PubMed and Cochrane Library in November 2019. A total of nine articles consisting of case-control or systematic reviews were selected based on publication date, main outcome, and the use of miRNAs or laparoscopy for diagnosis of endometriosis.

Results: The eight …

Biometric Prognosticators Of Future Myocardial Infarction: Bmi Vs. Waist To Hip Ratio, Christopher Hover

Capstone Showcase

Introduction: Myocardial Infarction (MI), better known as a heart attack, occurs when one or more of the coronary arteries becomes blocked or clogged to the point of being unable to perfuse myocardial tissue. Standard biometric measurements when visiting an outpatient care provider include height and weight which are converted into body mass index (BMI). BMI can sometimes be misleading in judging future health outcomes such as heart attacks. Therefore, this review analyzes the use of waist to hip ratio (I) to predict future myocardial infarctions (P) subsequently to prevent such events (O) compared to the traditionally used metric of BMI …
