Parallelization Of A Three-Dimensional Full Multigrid Algorithm To Simulate Tumor Growth, Dylan Goodin, Chin F. Ng, Hermann B. Frieboes

Commonwealth Computational Summit

We present the performance gains of an openMP implementation of a fully adaptive nonlinear full multigrid (FMG) algorithm to simulate three-dimensional multispecies desmoplastic tumor growth on computer systems of varying processing capabilities. The FMG algorithm is applied to solve a recently published thermodynamic mixture model that uses a diffuse interface approach with fourth-order reaction-advection-diffusion PDEs (Cahn-Hilliard-type equations) that are coupled, nonlinear, and numerically stiff. The model includes multiple cell species and extracellular matrix (ECM), with adhesive and elastic energy contributions in chemical potential terms, as well as including blood and lymphatic vessels represented as continuous vasculatures. Advection-reaction-diffusion PDEs are employed …

Finding Human Proteins That Bind To A Lassa Virus Protein, Maria Alejandra Pardo Ruge, Veronica J. Heintz, Douglas J. Lacount

The Summer Undergraduate Research Fellowship (SURF) Symposium

Viral hemorrhagic fevers are severe illnesses caused by many different viruses. Lassa Virus is one of these important pathogens in Western Africa, causing hemorrhagic fever and eventually death without early medical treatment. There is no vaccine and there is little information on host-pathogen interactions. Therefore, the interaction between viral proteins and host targets is useful to understand Lassa virus’s lifecycle and pathology, and to develop ways to prevent infection. In this project, we study the nucleoprotein of Lassa virus (NP), which has been reported to have anti-interferon (IFN) activity through elimination of double stranded RNA (dsRNA). These features could be …

Witcher, Rebekah Napier-Jameson, Hannah N. Lockwood, Josephine Taylor, Beatrice A. Clack, Judith M. Ball, Fabricio Medina Bolivar, Rebecca D. Parr

Undergraduate Research Conference

Rotavirus (RV) infections are a leading cause of severe gastroenteritis in infants and children under the age of five. There are two vaccines available in the United States and one in India that can be administered early in childhood, however they only protect against specific strains1. From our previous work, both arachidin-1 (A1) and arachidin-3 (A3) from peanut (Arachis hypogaea) hairy root cultures significantly inhibit simian RV replication2,3,4. The purpose of this study was to determine if a human intestinal cell line, HT29.f8, infected with a human RV, Wa, was affected by A1 and A3. Cell viability assays were utilized …

The purpose of my research is to show the correlation between modern vocal practices and the current medical technology available to help us understand the physiology of the voice. I am studying and analyzing the vocal performance and pedagogical practices from the early church to present day. I want to know why these vocal strategies have changed over time. There have been several different schools of thinking in regards to vocal practices. From the Italian style bel canto singing that was widely …

The Effect Of Photoactivated Tmp On Burkholderia Cepacia Biofilms, Reyna G. Osorio, Chandra N. Swiech, Tracy L. Collins

The Research and Scholarship Symposium (2013-2019)

Burkholderia cepacia is an opportunistic pathogen that causes infections in immunocompromised individuals such as cystic fibrosis patients. B. cepacia infections are typically characterized by the formation of complex communities of cells known as biofilms. Because B. cepacia biofilms are difficult to eradicate using antibiotics, it is important to pursue alternative treatment methods. Photodynamic therapy (PDT) is a type of therapy that uses light, a photosensitizer, and oxygen to elicit cell death through the production of reactive oxygen species. PDT has been shown in previous studies to be successful in killing both Pseudomonas aeruginosa and Staphylococcus aureus. In this study, we …

The Research and Scholarship Symposium (2013-2019)

Background

A rise in new schools of pharmacy has led to implementation of new curriculums. Pharmacy schools must adhere to standards set by the Accreditation Council of Pharmacy Education in order to provide knowledge of foundational sciences and prepare pharmacy students for the future. Prerequisites are typically foundational science courses taken early in the program so that students have the knowledge necessary to be excellent pharmacists. Within the Cedarville University School of Pharmacy, Biochemistry is a prerequisite course for Integrated Medicinal Chemistry and Pharmacology (PCoMedChem).

Objectives

The goal of this study is to determine if Biochemistry should remain a prerequisite …

The Use Of Rhyme, Rhythm, And Melody As A Form Of Repetition Priming To Aid In Encoding, Storage, And Retrieval Of Semantic Memories In Alzheimer’S Patients, Faiz Plastikwala

Virginias Collegiate Honors Council Conference

Treating Alzheimer’s disease, especially through non-pharmaceutical means, has become increasingly important over the past few decades. I examined the use of melody, rhyme, and rhythm as encoding mechanisms to aid in the retrieval of long term semantic information by juxtaposing previous experiments in the field. Melody, rhyme, and rhythm provide an organizational structure to facilitate the encoding of information. Specifically, chunking, the grouping of smaller units into larger ‘chunks’, helps facilitate long term encoding in patients, and is the byproduct of the organizational structure of a text. A major drawback of using these devices is the loss in the depth …

Undergraduate Research On General Aviation Hypoxia: A Student’S Perspective, Claire Schindler

Discovery Day - Prescott

During the fall academic term of 2016, an opportunity arose through the College of Aviation to serve as an undergraduate research assistant. Through discussion with faculty mentors, it was decided that a severely overlooked aspect of the aviation industry was survivors of hypoxia, especially in the less regulated general aviation community. The problem this study addresses is the uncertainty of the common circumstances that general aviation pilots find themselves in that create a hypoxic state, as well as whether or not that pilot reported the occurrence to the proper establishments. The results of this study showed not only those that …

P33. Design And Evaluation Of An Escherichia Coli Biomarker For Indication Of Ph, Kevin X. Zhou, Luana Langlois, Ashmita Singh, John Prince

Western Research Forum

Measuring pH is one of the most commonly used techniques in both the laboratory as well as the field due to its importance in a multitude of biochemical processes. Traditional methods of measuring pH may be highly developed in accuracy and precision but often involve disruption of the environment. Biological markers offer an alternative that allows for long-term pH monitoring. This innovative approach allows for vast applications such as in the manufacturing, food processing and research industries. Under moderate acidic conditions, the asr (acid shock RNA) gene is highly inducible and has been demonstrated to be crucial for growth at …

P03. Role Of Prefrontal Cortical Dopamine Transmission In Post-Traumatic Stress Disorder And Opiate Addiction Vulnerability, Jingjing Li

Western Research Forum

Background

PTSD and opiate addiction share strong co-morbidity and the inability to suppress obtrusive memory recall related to either stressful or rewarding experiences may be an underlying neuropsychological feature triggering PTSD and/or addiction. Our previous research has shown that dopamine (DA) transmission in the prefrontal cortex (PFC) strongly modulates emotional memory formation: activation of the DA D4 receptor (D4R) strongly potentiates the emotional salience of normally non-salient fear memories whereas DA D1 receptor (D1R) activation blocks the behavioural recall of fear memory. Thus, while intra-PFC D4 transmission strongly controls the acquisition of emotional memory, D1 transmission is selectively involved in …

P27. Acute Impact Of An Extremely Low Frequency Magnetic Stimulus On Human Neurophysiological Function - Magnetophosphene Perception, Cadence M. Baker

Western Research Forum

Background: Magnetophosphenes are classified as colourless, flickering lights that are perceived with closed eyes in the dark, and upon exposure to a magnetic field (MF). Uncertainties exist involving the MF threshold for magnetophosphene perception.

Methods: Forty subjects will be enrolled in this experiment aiming to provide a frequency-response curve of magnetophosphene perception under MF exposure. Subjects will sit in a whole head MF exposure device wearing a 64-channel MRI-compatible EEG cap. Subjects will be exposed to a MF with a frequency of 5-300 Hz, in the form of an increasing flux density ramp (increasing magnetic field flux density from 0-100 …

Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, Brandon J. Baer

Western Research Forum

Background: Bacterial pneumonia is a leading cause of death worldwide, with high mortality rates persisting even after antibiotic treatment. Current treatments for pneumonia involve administration of antibiotics, however after the bacteria are killed they release toxic substances that induce inflammation and lung dysfunction. Host defense peptides represent a potential solution to this problem through their ability to down regulate inflammation. However, effective delivery to the lung is difficult because of the complex branching structure of the airways. My study addresses this delivery problem by using exogenous surfactant, a pulmonary delivery vehicle capable of improving spreading of these peptides throughout the …

The Effect Of Auditory Stimulation On Human Movement Variability And Associated Cortical Involvement, Samuel Maaiah 9051573

UNO Student Research and Creative Activity Fair

The Biomechanics Research Building (BRB) is presently using functional near-infrared spectroscopy (fNIRS) to measure and understand brain activity during human movement and exercise. Compared to other brain activity measuring methods, which require subjects to remain very still during recording, fNIRS allows researchers to study brain activity while subjects perform a range of movement tasks. It is consequently a useful tool for studying movements (e.g. walking) that are not conducive to conventional methods of measuring brain activity. Experiments using fNIRS can vary dramatically in duration depending upon the research question. Some experimental methods contain multiple trials for short time intervals, while …
