Neuronal Degeneration And Short-Term Memory Impairment After Tbi, Obiamaraije Igwe

Posters-at-the-Capitol

Traumatic brain injury (TBI) was associated with impaired short-term memory with causes of vehicle accidents and falls. Protein plaques containing fibrinogen (Fg), are associated with memory loss. After TBI, Fg in blood was higher than normal (>~2 mg/ml), which resulted in increased Fg in extravascular space. Therefore, Fg bonded to its endothelial receptor intercellular adhesion molecule-1 (ICAM-1). Fg then interacted with cellular prion protein (PrPC), which had a strong effect on the loss of memory and cognition. Mechanisms of Fg and PrPC complex formation and its functional implication are not known. This present study tested the level of Fg-PrPC …

E,E-Farnesol Inhibits Swarming Motility In Burkholderia Cepacia Through Rhamnolipid Production, Stephanie E. Nicholls, Alayna N. Sanderson, Andrea P. Schwartz, Lauren E. Ward, Jessica N. Weisensee, Molly Yandrofski, Tracy L. Collins

The Research and Scholarship Symposium (2013-2019)

Burkholderia cepacia and Candida albicans both exhibit cell-to-cell communication through the use of quorum-sensing molecules (QSM) known as autoinducers. E,E-farnesol is a QSM produced by C. albicans which regulates its conversion from yeast to mycelium. Because there is a positive correlation between the presence of B. cepacia and C. albicans in the lungs of individuals with cystic fibrosis (CF), we examined whether E,E-farnesol had an effect on swarming motility in B. cepacia. Swarming motility was inhibited when B. cepacia was exposed to 250 µM of E,E-farnesol. In addition, there was a 26.8% decrease in rhamnolipid production when cells were grown …

Spatial And Temporal Variability Of Water Quality Parameters In Cedar Lake (Cedarville, Ohio), Laura A. Cashman, William A. Smith, Shannon L. Swicker, Abigail L. Williams, Mark A. Gathany

The Research and Scholarship Symposium (2013-2019)

Cedar Lake is a man-made lake that is central to Cedarville University’s campus. This focal point of the campus is a source of aesthetic appeal and beauty of Cedarville University. The lake ranges in depth from 0.6-3.7m, is 140m by 150m across, an approximate volume of 40,000 m³ and demonstrates normal capabilities to support fish and other life. There is, however, some concern over Cedar Lake’s level of productivity as undesirable algae blooms are common during warmer months. In October and November 2016 we began to assess the spatial and temporal variability of water chemistry by measuring temperature (℃), …

Quantitative evaluation of Clinostomum marginatum distribution in the fish host (Perca flavescens): Investigation of the impact on functional performance

Clinostomum marginatum is a trematode commonly found in freshwater fish. The adult C. marginatum stays in its definitive avian host’s mouth and throat. It releases eggs upon contact in water and the eggs hatch into a free-swimming miracidia, which infects an aquatic snail as the first intermediate host. The miracidia, then, develops into a cercaria and leaves the snail to find a fish as its second intermediate …

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 …

Assessment Of Olfactory-Based Social Recognition: Designing A Paradigm For Marmosets, Stephanie Womack

UNO Student Research and Creative Activity Fair

Navigation of the social world depends largely on one’s responsiveness to social stimuli and information from a wide range of senses can be used to discriminate between individuals. Mammals use several sensory modes to communicate and respond to their surroundings, but olfaction is the dominant sense across most species. Chemosignals provide a wealth of information including sex, age, reproductive status, and individual identity. Currently, assessment of olfaction is largely limited to the habituation-dishabituation paradigm or the two-choice discrimination task used primarily in rodents. These paradigms are limited by their reliance on inherent reward of interaction with stimuli without providing additional …

Gait Biomechanics In Patients With Peripheral Artery Disease After Revascularization, Sarah Baker

UNO Student Research and Creative Activity Fair

Peripheral artery disease (PAD) is a cardiovascular disease manifesting blockages to arteries while limiting blood flow to the legs. Patients with PAD have pain/tingling in calves, thighs, and/or buttocks emanating by physical activity called intermittent claudication. PAD causes physical function limitations and increases cardiovascular morbidity by 3-6 times. PAD becomes particularly more prevalent with age. Patients with PAD walk differently than their healthy counterparts. Surgical revascularization to restore blood flow is the typical intervention, but whether walking patterns are restored following surgery has not been studied. This study compared walking patterns of patients with PAD at baseline and six-months post-revascularization. …
