Muscle Oxygenation In Patients With Peripheral Artery Disease During Walking With And Without An Ankle Foot Orthosis, Anthony Arellano, Hafizur Rahman, Iraklis Pipinos, Jason Johanning, Sara Myers

UNO Student Research and Creative Activity Fair

Peripheral artery disease (PAD) is a cardiovascular disease caused by blockages in the arteries that reduce blood flow to the peripheral limbs. Claudication, a prominent symptom of PAD is a condition in which the lack of blood flow causes an inability to meet the metabolic demands of the muscle tissue, causes severe cramping pain. Previous studies have shown muscle oxygenation starts significantly lower and declines faster in patients with PAD compared to healthy controls. An ankle foot orthosis (AFO) can provide walking assistance by absorbing and returning the mechanical force during walking. We hypothesized oxygenation levels would be higher in …

An Investigation Of Stimulants: Reviewing Their Effects On The Brain, Including Memory And Microglia, Michael Douchey

UNO Student Research and Creative Activity Fair

Stimulants are a class of drugs that have a variety of effects on the brain, including changes in receptor activity in the brain areas responsible for- memory, attention, emotion, motor control, and the reward pathway. Stimulants may be generally classified by their availability. For example, prescription stimulants, which include drugs such as methylphenidate (Concerta™, Ritalin™) and mixed amphetamine salts (Adderall™), must be prescribed by medical professionals. Another regulated stimulant, albeit one available without a prescription, is nicotine; a highly addictive chemical that is age-restricted by the U.S. federal government. Nicotine is found in tobacco products, and in tobacco-free alternatives including …

Prior research has focused on functional treatment of the upper limbs but has lacked observance of the effects that prosthetics and limb loss incur to the trunk. Therefore, the purpose of this study is to examine the acute effects …

Impacts Of Dietary Nitrate On Endothelial Function, Arterial Stiffness, And Systemic Vascular Pressure In Peripheral Arterial Disease, Elizabeth J. Pekas, Steven D. Scott, Ronald J. Headid Iii, Michael D. Shukis, Jeonghwa Shin, Jiwon Song, Song-Young Park

UNO Student Research and Creative Activity Fair

Peripheral arterial disease (PAD) is the manifestation of atherosclerotic plaque in the larger arteries of the legs, which results in impaired blood flow to the lower extremities. Markers of vascular health, including endothelial function and arterial stiffness, have been shown to be attenuated in PAD.

Purpose: We sought to examine the effects of a nitrate supplement (body mass-normalized dosage of beetroot juice) on vascular function measurements such as endothelial function, arterial stiffness, and central and peripheral blood pressure in patients with PAD. We hypothesized that acute intake of a nitrate supplement would improve vascular function.

Methods: PAD patients (stage II-III, …

Large Scale Dynamical Model Of Macrophage/Hiv Interactions, Sean T. Bresnahan, Matthew M. Froid

UNO Student Research and Creative Activity Fair

Properties emerge from the dynamics of large-scale molecular networks that are not discernible at the individual gene or protein level. Mathematical models - such as probabilistic Boolean networks - of molecular systems offer a deeper insight into how these emergent properties arise. Here, we introduce a non-linear, deterministic Boolean model of protein, gene, and chemical interactions in human macrophage cells during HIV infection. Our model is composed of 713 nodes with 1583 interactions between nodes and is responsive to 38 different inputs including signaling molecules, bacteria, viruses, and HIV viral particles. Additionally, the model accurately simulates the dynamics of over …

Perceptions Of Physical Activity While Breastfeeding: 
A Mixed Methods Approach, Kailey Snyder

The Energy Paradox Of The Ankle-Foot Complex During Human Walking, Nikolaos Papachatzis, Kota Takahashi

UNO Student Research and Creative Activity Fair

Flexor hallucis longus (FHL) is a multiarticular muscle that possesses the potential to alter foot’s functional and mechanical behavior, since it performs multiple significant functions during walking (e.g supports the medial longitudinal arch of the foot).The purpose of this study was to determine if the functional changes of the FHL are associated with the foot’s adaptations to the mechanical demands of walking. Backward walking is an experimental method capable of altering how the forces propagate underneath the foot and disrupting the mechanical function of the FHL muscle. We hypothesized that: (1) the muscle activity of the FHL will increase during …

Consideration Of Colloids And Crystalloids In Fluid Management, Gregory Van Dyke

Physician Assistant Capstones

The average adult is roughly comprised of 50-60% water that embodies the intracellular and extracellular space.1 Extracellular space is further broken into the interstitial, intravascular, and transcellular spaces. Because crystalloids are small molecules, most providers are concerned about the interstitial edema associated with revascularization. Critical illness causes inflammatory states that leads to endothelial dysfunction associated with interstitial edema. Since one significant downside of crystalloid administration is fluids crossing the permeable membrane, colloids can complete resuscitation without changing oncotic pressure and avoiding edema while increasing intravascular expansion. Due to the increased molecular weight and larger molecules associated with colloids, it is …

Data Integration And Interoperability For Patient-Centered Remote Monitoring Of Cardiovascular Implantable Electronic Devices, Carly Daley, Tammy Toscos Phd, Michael Mirro

Mirro Center Articles

Abstract: The prevalence of cardiovascular implantable electronic devices with remote monitoring capabilities continues to grow, resulting in increased volume and complexity of biomedical data. These data can provide diagnostic information for timely intervention and maintenance of implanted devices, improving quality of care. Current remote monitoring procedures do not utilize device diagnostics to their potential, due to the lack of interoperability and data integration among proprietary systems and electronic medical record platforms. However, the development of a technical framework that standardizes the data and improves interoperability shows promise for improving remote monitoring. Along with encouraging the implementation of this framework, we …
