Proliferative vitreoretinopathy (PVR) is a complication of rhegmatogenous retinal detachment and ocular trauma. The disease is characterized by development of membranes that may apply traction to the retina and cause redetachment. Membrane contractions are attributed to myofibroblasts arising from retinal pigment epithelial cells, glia and fibroblasts. The progenitors of myofibrobasts in the lens are Myo/Nog cells that express the skeletal muscle transcription factor MyoD and bone morphogenetic protein inhibitor Noggin. The retina and choroid also contain Myo/Nog cells that respond to stress. We examined preretinal PVR membranes from three ocular trauma patients with retinal detachment for Myo/Nog ...
The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl
Senior Theses and Projects
Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ ...
Melanopsin-Expressing Retinal Ganglion Cells In Control Vs. Glaucomatous Retinas, 2020 The University of Akron
Melanopsin-Expressing Retinal Ganglion Cells In Control Vs. Glaucomatous Retinas, Edward Hamad
Williams Honors College, Honors Research Projects
Glaucoma is a common cause of vision loss worldwide and has a large scope of symptoms, ranging from pupillary reflex defects to sleep disorders. These issues can be explained partially by a recently found subtype of retinal ganglion cells that express melanopsin, denoted melanopsin-expressing retinal ganglion cells or mRGCs for short. These cells function primarily as photoreceptors in the non-image forming pathway, but can receive input from rods and cones. Since mRGCs play a role in the pupillary reflex and regulation of the sleep-wake cycle, I investigated if glaucoma leads to the degeneration of these cells in a mouse model ...
Counseling For Patients With Hyperacusis, 2019 Augustana College, Rock Island Illinois
Counseling For Patients With Hyperacusis, Mary Maraist
Communication Sciences and Disorders: Student Scholarship & Creative Works
Hyperacusis is the phenomenon of experiencing moderately loud sounds as overly loud and/or intensely annoying. Hyperacusis can also cause fear or pain in response to sound. There is no one known cause of hyperacusis, and because of the variety of ways it presents itself, the approximate prevalence is difficult to determine. Despite the ambiguity of hyperacusis, the audiologist is an important part of diagnosing and educating clients with hyperacusis. During this project we aimed to discover the challenges individuals with hyperacusis face. These include anxiety, depression and avoidance behavior, and sometimes co-occurring tinnitus and hearing loss. Another aim was ...

Fluorometholone Modulates Gene Expression Of Ocular Surface Mucins, 2019 Chapman University
Fluorometholone Modulates Gene Expression Of Ocular Surface Mucins, Jonathan Taniguchi, Ajay Sharma
Pharmacy Faculty Articles and Research
Mucins are vital to keep the ocular surface hydrated. Genes encoding for mucins contain a glucocorticoid response element. The purpose of this study was to evaluate the effect of fluorometholone, a glucocorticoid receptor agonist used in the management of dry eye, on the gene expression of conjunctival and corneal epithelial cell mucins.
Stratified cultures of human conjunctival and corneal epithelial cells were exposed to 25, 50 and 100 nM of fluorometholone alone or in presence of mifepristone, a glucocorticoid receptor antagonist. The mRNA was isolated from the cells and reverse transcribed to cDNA. The cDNA was used for ...
The Sacred Touch Of Hallowed Hands: Tracing The Holy Through The Haptic In George Eliot’S Early Work, 2019 College of William and Mary
The Sacred Touch Of Hallowed Hands: Tracing The Holy Through The Haptic In George Eliot’S Early Work, Katharine Isabel Williams
Undergraduate Honors Theses
From the outstretched hand in “Janet’s Repentance,” through the hands that mingle with the soil in Adam Bede, to the lovingly clasped hands in The Mill on the Floss, the hand plays a remarkable, multi-faceted role in George Eliot’s early fiction. Eliot was writing in an era when the conception of the hand was changing; its sensory capacity was a subject of exploration, its relationship to work was shifting, and its conduct was policed. Eliot uses this dynamic cultural significance, alongside the hand’s established biblical meaning, to negotiate issues ranging from religion to gender to work to ...
The Effects Of Ocular Dominance On Visual Processing In College Students, 2019 James Madison University
The Effects Of Ocular Dominance On Visual Processing In College Students, William Alexander Holland
James Madison Undergraduate Research Journal (JMURJ)
The role of ocular dominance in processing visual memory and analytic tasks is unknown. Research has variably showed both significant effects and no effect of ocular dominance on visual perception, motor control, and sports performance. The goal of this study was to determine if there is a relationship between ocular dominance and visual processing under a variety of computer gaming tasks. This was accomplished by first determining subjects’ ocular dominance through the Miles test, and then examining the subjects’ visual performance on four different Lumosity games under three conditions: left eye, right eye, and both eyes. Results suggest a relationship ...

How asymmetries in motor behavior become established normally or atypically in mammals remains unclear. An established model for motor asymmetry that is conserved across mammals can be obtained by experimentally inducing asymmetric striatal dopamine activity. However, the factors that can cause motor asymmetries in the absence of experimental manipulations to the brain remain unknown. Here, we show that mice with inner ear dysfunction display a robust left or right rotational preference, and this motor preference reflects an atypical asymmetry in cortico-striatal neurotransmission. By unilaterally targeting striatal activity with an antagonist of extracellular signal-regulated kinase (ERK), a downstream integrator of striatal ...
Water Transport In The Lateral Line Canal Of The Intertidal Fish Xiphister Mucosus (Girard 1858) And Its Significance To Evaporative Water With Preliminary Observations Of The Metabolic Consequences Of Water Loss, 2018 Portland State University
Water Transport In The Lateral Line Canal Of The Intertidal Fish Xiphister Mucosus (Girard 1858) And Its Significance To Evaporative Water With Preliminary Observations Of The Metabolic Consequences Of Water Loss, Whitney Anne Gayer
Dissertations and Theses
The lateral line canal system is a sensory organ found in all teleost fish that has a wide range of morphological variation. Variation in morphology may often be the result of evolutionary necessity where the need for function dictates form. Xiphister mucosus is an amphibious Stichaeid fish that inhabits the rocky intertidal zone of the northeastern Pacific Ocean. The rocky intertidal is considered an extreme environment where crashing waves and ebbing tides may require the specialization of adaptations for surviving the many abiotic stressors encountered there.
The lateral line trunk canal of Xiphister is regarded as unique among teleosts with ...
Changes In Balance And Joint Position Sense During A 12-Day High Altitude Trek: The British Services Dhaulagiri Medical Research Expedition, 2018 Northern Michigan University
Changes In Balance And Joint Position Sense During A 12-Day High Altitude Trek: The British Services Dhaulagiri Medical Research Expedition, Sarah B. Clarke, Kevin Deighton, Caroline Newman, Gareth Nicholson, Liam Gallagher, Christopher J. Boos, Adrian Mellor, David R. Woods, John P. O'Hara
Postural control and joint position sense are essential for safely undertaking leisure and professional activities, particularly at high altitude. We tested whether exposure to a 12-day trek with a gradual ascent to high altitude impairs postural control and joint position sense. This was a repeated measures observational study of 12 military service personnel (28±4 years). Postural control (sway velocity measured by a portable force platform) during standing balance, a Sharpened Romberg Test and knee joint position sense were measured, in England (113m elevation) and at 3 research camps (3619m, 4600m and 5140m) on a 12-day high altitude trek in ...
Il-1r And Myd88 Contribute To The Absence Of A Bacterial Microbiome On The Healthy Murine Cornea, 2018 Touro University California

Faculty Publications & Research of the TUC College of Pharmacy
Microbial communities are important for the health of mucosal tissues. Traditional culture and gene sequencing have demonstrated bacterial populations on the conjunctiva. However, it remains unclear if the cornea, a transparent tissue critical for vision, also hosts a microbiome. Corneas of wild-type, IL-1R (-/-) and MyD88 (-/-) C57BL/6 mice were imaged after labeling with alkyne-functionalized D-alanine (alkDala), a probe that only incorporates into the peptidoglycan of metabolically active bacteria. Fluorescence in situ hybridization (FISH) was also used to detect viable bacteria. AlkDala labeling was rarely observed on healthy corneas. In contrast, adjacent conjunctivae harbored filamentous alkDala-positive forms, that also labeled with ...
Distortion In Body Schema: The Influence Of Body Fat And Mass On Perceptions Of Personal Size, Katarina Ann Ferrucci
Senior Projects Spring 2017
Obesity has been linked with a myriad of negative outcomes for both physical and mental health including feeding and eating disorders and cognitive impairments that affect perception of body size. Understanding the cognitive mechanisms and physiological factors that contribute to perception of body size may help us to comprehend how obesity impacts the construction and development of one’s mental body representations. Previous research by Scarpina, Castelnuovo, and Molinari (2014) suggests that, compared to those with a normal Body Mass Index, individuals with a BMI greater than 30 (obese) not only inaccurately estimate tactile and mental distances on their own ...
Contributions Of Myd88-Dependent Receptors And Cd11c-Positive Cells To Corneal Epithelial Barrier Function Against Pseudomonas Aeruginosa, Matteo M. E. Metruccio, Connie Tam, David J. Evans, Anna L. Xie, Michael E. Stern, Suzanne M. J. Fleiszig
Faculty Publications & Research of the TUC College of Pharmacy
Previously we reported that corneal epithelial barrier function against Pseudomonas aeruginosa was MyD88-dependent. Here, we explored contributions of MyD88-dependent receptors using vital mouse eyes and confocal imaging. Uninjured IL-1R (−/−) or TLR4 (−/−) corneas, but not TLR2 (−/−), TLR5 (−/−), TLR7 (−/−), or TLR9 (−/−), were more susceptible to P. aeruginosa adhesion than wild-type (3.8-fold, 3.6-fold respectively). Bacteria adherent to the corneas of IL-1R (−/−) or TLR5 (−/−) mice penetrated beyond the epithelial surface only if the cornea was superficially-injured. Bone marrow chimeras showed that bone marrow-derived cells contributed to IL-1R-dependent barrier function. In vivo, but not ex vivo, stromal CD11c+ cells responded to bacterial challenge ...

An Investigation Into Spike-Based Neuromorphic Approaches For Artificial Olfactory Systems, Anup Vanarse, Adam Osseiran, Alexander Rassau
ECU Publications Post 2013
The implementation of neuromorphic methods has delivered promising results for vision and auditory sensors. These methods focus on mimicking the neuro-biological architecture to generate and process spike-based information with minimal power consumption. With increasing interest in developing low-power and robust chemical sensors, the application of neuromorphic engineering concepts for electronic noses has provided an impetus for research focusing on improving these instruments. While conventional e-noses apply computationally expensive and power-consuming data-processing strategies, neuromorphic olfactory sensors implement the biological olfaction principles found in humans and insects to simplify the handling of multivariate sensory data by generating and processing spike-based information. Over ...

“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, 2016 Liberty University
“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams
Senior Honors Theses
Alan Turing asked if machines can think, but intelligence is more than logic and reason. I ask if a machine can feel pain or joy, have visions and dreams, or paint a masterpiece. The human brain sets the bar high, and despite our progress, artificial intelligence has a long way to go. Studying neurology from a software engineer’s perspective reveals numerous uncanny similarities between the functionality of the brain and that of a computer. If the brain is a biological computer, then it is the embodiment of artificial intelligence beyond anything we have yet achieved, and its architecture is ...
