Art Conservation Master's Projects
A severely damaged 19th-century oil painting depicting a portrait of a woman was treated at Patricia H. and E. Garman Art Conservation Department. A typed letter provided by the owner mentioned that it has been previously restored yet returned with unsatisfactory results. After further examination, the painting appeared to have been previously treated multiple times by different people. There was overpaint distinctly present on the face and later discovered to be present overall. The full state of condition of the painting was initially unknown due to the sum of the surface being overpainted. However, there were evidence of paint loss …

The Effects Of Light Cycle Disruption On The Reactive Oxygen Species Production In Zebrafish, Talia Sanders
Honors College Theses
It has been proven that maintaining homeostasis is linked to regulation of circadian rhythms and the light cycles associated with them. Through investigation of zebrafish mitochondria subject to stress via unpredictable light cycle exposure, we previously studied the level of GSK3β protein as it relates to the health of the brain. The data has shown that when a brain undergoes stress, it results in the increased activation of GSK3β which leads to disruptions in circadian rhythm, inflammation, and cell death. Moreso, this overexpression results in reduced ATP production and lowered Complex 1 activity in the mitochondria. However, GSK3β activation is …

In Silico Identification Of Small Molecule Agonist Binding Sites On Kcc2, Kenyon Mitchell, Alfred Amendolara, Ruth Hunter, Jaden Miner, Andrew Payne
Annual Research Symposium
Purpose: Potassium-Chloride Cotransporter 2 (KCC2) is a neuronal membrane protein specific to the central nervous system. It is responsible for removing Cl- ions from the intracellular space, maintaining a normal Cl- gradient essential for proper function at inhibitory synapses. Dysregulation causes an upward shift in the Cl- reversal potential resulting in a hyperexcitable state of the postsynaptic neuron. Existing literature indicates that KCC2 may be involved in the addiction pathway of a variety of drugs of abuse, including opioids and alcohol. This makes KCC2 an attractive potential drug target when treating substance use disorders. A novel direct KCC2 agonist, VU0500469, …
Associations Between Early Childhood Sleep, Memory Function, And Brain Development Across The Nap Transition,

Associations Between Early Childhood Sleep, Memory Function, And Brain Development Across The Nap Transition, Sanna Lokhandwala
Doctoral Dissertations
Preschool-age children often distribute their sleep across a midday nap and overnight sleep. Skipping the nap is suggested to increase the duration and depth of deep sleep (i.e., slow wave activity; SWA). Moreover, missing the midday nap has been shown to impair learning processes. This may be because children’s brains at this point in development are immature, necessitating the intervening nap period to strengthen memories before they are forgotten. Nonetheless, at some point during the preschool years, many children begin transitioning naturally out of napping. It is unclear whether the memory benefits of overnight SWA after a skipped nap depend …

Checking For Ticks: Analyzing The Efficiency Of Different Tick Collection Methods, Peter Briggs, Lawson Trimmell, Javier Monzón
Seaver College Research And Scholarly Achievement Symposium
Ticks are the most important arthropod disease vectors in both North America and Europe. Field collection of wild ticks is vital for research on the ecology of vector-borne diseases. Dragging and trapping are the two most common methods for collecting wild ticks. Dragging involves a researcher pulling a canvas through a field to collect ticks searching for a host, while trapping exploits ticks’ natural attraction to carbon dioxide to lure them onto a canvas where they get caught on tape. Our study aimed to evaluate which of these two methods is more effective. We chose six sites across three states, …

Library/Life Sciences Undergraduate Poster Competition 2024
One of the most important tests in the clinical laboratory is the Complete Blood Count, which involves identifying the white blood cells in a patient’s blood. The respective counts of the different white blood cell types correlate with various states of health and disease and are critical to diagnosing diseases such as leukemia. Leukemic cells (blasts) are considered especially difficult to distinguish, and it is of the upmost importance that these cells are identified correctly. To aid in the process of leukemic cell identification, we quantified fractal patterns in the chromatin of white blood cells and used the data to …

A Dietary Variety: Analyzing The Impacts Of Diverse Vs Worm-Exclusive Diets On The Blanding’S Turtle (Emydoidea Blandingii), Caitlin F. Copenhaver
Honors Theses
The endangered Blanding’s turtle (Emydoidea blandingii) is a species with a generally diverse diet in their freshwater wetland habitats; they consume prey such as crayfish and snails. In captivity, these options often become more limited due to logistical reasons. As ex situ conservation efforts such as captive rearing and head-starting are becoming more popular for this species, it will be important to gain more insight on how these more limited diets might affect these turtles. This study describes a comparison between diets in six captive Blanding’s turtles from September to November of 2023, with three turtles receiving only …

It is so important to explore the potential side effects of antidepressants especially if these side effects could lead to a future detriment to an individual’s financial and social well-being. A better understanding of these side effects in regards to human developmental issues is imperative considering issues related to mental health and depression affect a large percentage of the population. In this study, we tested if Caenorhabditis (C.) elegans could be a potential model organism to predict possible side effects associated with select antidepressants. Their developmental problems potentially encountered upon drug treatment may be encountered in humans.

Sulforaphane Pre-Treatment Improves Cytoprotection Against Opportunistic Pathogens, Robert Darby, Nathan Clark
Annual Research Symposium
Alcohol is associated with increased mortality and morbidity globally. Pulmonary infections with opportunistic pathogens can occur in healthy humans; however, binge alcohol intoxication (≥ 0.08% BAC) is a major risk factor. We have previously shown that a single dose of alcohol comparable to binge alcohol intoxication increases infection by reducing alveolar macrophage function in vivo. The aim of this study was to 1) test the therapeutic potential of the phytonutrient sulforaphane (SFN) given as a pre-treatment, and 2) test the alcohol-induced effects on phagocytic function in murine and human macrophages in vitro.

Investigating The Impact Of Ozempic Treatment On Alcohol Consumption In Individuals With Class 1 And Class 2 Obesity, Yvannia Gray, Selin Karadag
Annual Research Symposium
The purpose of this experiment is to see if there is a correlation between Ozempic (semaglutide) treatment for weight loss and alcohol consumption. Ozempic is a glucagon-like peptide-1 (GLP-1) agonist that lowers blood sugar and appetite as it mimics the effects of GLP-1. In previous studies involving rodents, it has been shown that GLP-1 agonists can also be used to reduce addictive substance intake. We hypothesize that subjects who receive Ozempic treatment will exhibit reduced consumption of alcohol over the span of a month compared to subjects who do not receive Ozempic treatment.

Ksp1 Is An Autophagic Receptor Protein For The Snx4-Assisted Autophagy Of Ssn2/Med13, Sara E Hanley, Stephen D Willis, Steven J Doyle, Randy Strich, Katrina F Cooper
Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship
Ksp1 is a casein II-like kinase whose activity prevents aberrant macroautophagy/autophagy induction in nutrient-rich conditions in yeast. Here, we describe a kinase-independent role of Ksp1 as a novel autophagic receptor protein for Ssn2/Med13, a known cargo of Snx4-assisted autophagy of transcription factors. In this pathway, a subset of conserved transcriptional regulators, Ssn2/Med13, Rim15, and Msn2, are selectively targeted for vacuolar proteolysis following nitrogen starvation, assisted by the sorting nexin heterodimer Snx4-Atg20. Here we show that phagophores also engulf Ksp1 alongside its cargo for vacuolar proteolysis. Ksp1 directly associates with Atg8 following nitrogen starvation at the interface of an Atg8-family interacting …

Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …

The objective of this study is to fabricate solid-contact ion selective electrodes (SC-ISEs) that have long term stable potential. Various conducting polymers such as polyaniline and its derivatives have been successfully employed to improve the potential stability in SC-ISEs. Recently, the role of hydrophobicity at the interface between the conducting polymer solid contact and the ion sensing membrane has been investigated and figured out that the hydrophobic interfaces preclude water layer formation that deteriorate the SC-ISEs potential stability and reproducibility. In this work, a hydrophobic polyaniline derivative was fabricated on the surface of a glassy carbon electrode by electropolymerization of …

Doctoral Dissertations
N2O is a long-recognized greenhouse gas (GHG) with potential in global warming and ozone depletion. Terrestrial ecosystems are a major source of N2O due to imbalanced N2O production and consumption. Soil pH is a chief modulating factor controlling net N2O emissions, and N2O consumption has been considered negligible under acidic conditions (pH <6). In this dissertation, we obtained solids-free cultures reducing N2O at pH 4.5. Furthermore, a co-culture (designated culture EV) comprising two interacting bacterial population was acquired via consecutive transfer in mineral salt medium. Integrated phenotypic, metagenomic and metabolomic analysis dictated that the Serratia population excreted certain …
