Role Of Emotion Regulation In The Relationship Between Fears Of Evaluation And Social Anxiety, Jaismeen Dua

Masters Theses

Cognitive components influencing social anxiety have been well-researched for decades, especially fear of negative evaluation (Clark & Wells, 1995; Hofmann, 2007; Rapee & Heimberg, 1997; Schlenker & Leary, 1982). Relatively recent and emerging research has suggested a strong link between fear of negative evaluation and fear of positive evaluation, and how both of them influence social anxiety (Weeks, Heimberg, & Rodebaugh, 2008; Weeks et al., 2007; Weeks & Howell, 2012; Weeks et al., 2009). This study examined social anxiety in relation to both fear of negative evaluation and fear of positive evaluation. Findings from the study replicated previous research results, …

Synthesis, Characterization And Mechanistic Studies Of Biomimetic Dinuclear Copper(Ii) Complexes, Millaniyage Nuwanthaka Prasad Jayaweera

Masters Theses

Dinuclear copper complexes are significant synthetic targets due to their use as model compounds for the active sites of type 3 copper proteins like catechol oxidase. A distinct class of ligands used in these studies are built on a phenol core to witch various donor side-arms were appended at the 2 and 6 positions of the arene ring. In our quest to quantify the influence of electron donating or withdrawing groups attached to the central arene ring, we have designed a set of ligands that, upon coordination to copper(II) centers, would produce complexes of the general structure. During this research …

Developing A Basket-Shaped Host Molecule Based On P-Tert-Butylcalix[4]Arene Featuring Urea Groups For Encapsulating Volatile Guest Molecules, Lokugama Widanelage Vidula Priyadarshana

Masters Theses

Molecular baskets are a group of synthetic host molecules which are designed to govern the inclusion of small guest molecules. The basic structural features of basket-shaped host molecules are a cavity for holding a much smaller guest molecule and tunable gates for keeping the guest molecule inside. These types of gates can be tuned by changing temperature, concentration, pH, etc. In this research group's previous study, a molecular basket of cal ix[ 4]arene with carboxylic acid groups was synthesized by functionalizing calix[4]arene's phenol hydroxyl groups with benzyl bromide building blocks. In the study detailed here, 1 , l '-((5-(bromomethyl)-1,3-phenylene)bis(methylene))bis(3-isopropylurea) was …

The Transcriptional Response Of Phanerochaete Chrysosporium And Trametes Versicolor To Growth On Stems Of Helianthus Argophyllus (Silverleaf Sunflower), Nadh Hamoud Alsubaie

Masters Theses

Traditional physicochemical and physicomechanical pretreatment technologies have improved the deconstruction of lignocellulose, but often require high energy inputs and added chemical reagents. Recent studies have demonstrated the use of white-rot fungi as alternative biological pretreatment agents that can mitigate these concerns. Although, white-rot fungi have been shown to grow on a variety of non-woody substrates, they have not been explored with respect to sunflower, which has the potential to provide raw materials for both biodiesel and bioethanol. In the present study, Silverleaf sunflower stems (Helianthus argophyllus) were used as substrates for the white-rot fungi Phanerochaete chrysosporium and Trametes …

Creg1: Its Role As A Master Regulator Of Liver Function, Iffat Jahan

Masters Theses

Mammalian development involves a complex system of regulatory signals and reactions resulting in highly differentiated cell types with specific structure and function. The liver is a major organ that has been studied extensively to understand underlying genetic processes responsible for specification, establishment and maintenance of tissue identity. Hepatoma and hepatoma variant cell lines have been used as models to understand genetic networks responsible for liver function. Whole genome microarray analysis of hepatocyte cell lines has revealed candidate genes that may serve as regulators or master regulators of liver specificity. In two previous studies in our lab, the role of candidate …

Uridine Promotes Neurite Outgrowth In Neuro2a Cells, Jacquelyn Spathies

Undergraduate Honors Theses

Neurodegenerative diseases such as Alzheimer's and Parkinson's are the main causes of age-related dementia. These diseases can be due to neuronal cell death and/or impairment of neurite outgrowth. Giant oyster mushroom (GOM), Pleurotus giganteus, is used as a nootropic to improve cognitive function. GOM can also be used to prevent the onset of dementia. The underlying mechanism behind the medicinal property of GOM is unclear. Previous studies have shown that GOM has a high concentration of uridine. In this study, I examined the effects of uridine on neurite outgrowth in the Neuro-2a (N2a) neuroblastoma cell line. We also examined …

Genomic Dysregulation By Overexpression Of Transcription Factors, Mackenzie Scroggins

Undergraduate Honors Theses

As one of the major organs, the liver plays vital roles in the homeostasis of an individual. Being able to identify master regulator genes, genes whose product can affect the activation or deactivation of other genes, will enrich our understanding of hepatic function and liver disease. Previously, our lab used genome-wide microarray data to identify several transcription factors that may play a key role in liver expression. Here we ask whether overexpression of these transcription factors in a non-liver cell would result in liver phenotype activation or general disruption of gene regulation. To this end, we stably introduced seven transcription …

Exploration Of Sonic Hedgehog Gene Expression In Fathead Minnows (Pimephales Promelas), Brooke Renee Greiner

Undergraduate Honors Theses

Pollutants, as a result of wastewater treatments, have been shown to have negative impacts on aquatic ecosystems. To better understand the possible consequences caused by effluents on ecosystems, it is important to examine ecotoxicology data. One of the most commonly used species for water quality testing is the fathead minnow, Pimephales promelas. Ecotoxicology can then be taken one step further to understand the effects of pollutants on a molecular level. Previous research had identified effluents as causes for abnormal minnow fin morphology. In order to collect additional data on development, tanks with fathead minnows were placed at the Charleston …

Time Perception After Emotional Induction, Abigail Crowne

Undergraduate Honors Theses

Current literature establishes trends where valent stimuli can create a subjective experience of retrospective or prospective time. The purpose of this study is to examine the consequences of estimating time that has passed as a result of valence mood induction. Time seems to pass more slowly when we are not in a pleasant state. What if a self-induced mood could change our perception of time that has passed? To answer this question, our study required participants to write about specific memories about incidents of joy or sadness, or about the classroom around them for a control condition. There was no …

Reprogramming Of Rat Hepatoma Cells With Fibroblast-Specific Protein Twist1, Kezban Ucar Cifci

Masters Theses

In mammalian development, a complex system comprised of regulatory signals causes tissue distinction with unique structures as well as functions. Gene expression controls these functions through specific combinations of transcription factors and cofactors that influence cell differentiation by both activation and repression of genes.

Whole genome microarray studies of fibroblasts have identified candidate genes that can serve as master regulators of fibroblast identity. A previous study showed that Prrx1 and Snai2 play important roles in activating expression of fibroblast identity, and Snai2 overexpression in hepatoma cells (Fg14) activated expression of fibroblast specific genes. Moreover, Snai2 overexpression resulted in repression of …

Single Parent Households And The Effect On Student Learning, Asia Watt

Masters Theses

The purpose of this research is to examine if there is a relationship between single-parent households and the effect on student learning. A total of seven parents and three elementary teachers took a survey. Students’ scores in math and reading from report cards and PARCC scores were also used as data sources. Results revealed that the involvement of single parents at school varies depending on the type of involvement, however, data from the report card review showed all the parents review their child’s report card. Approximately 70 % or more assisted their children in math and English homework. In addition, …

Investigating The Prevalence Of An Insecticide Resistance Gene In Culex Mosquito Populations Of Central Illinois, Kylee R. Noel

Masters Theses

The globalization of society has led to the spread of the vectors, mosquitoes, and diseases. Each year millions of people are killed by diseases vectored by mosquitoes. For example, West Nile Virus alone killed over 2,000 people in North America in 2017; 8 of those deaths being in Illinois. Two prominent vectors of West Nile Virus are Culex pipiens and Culex restuans; which are difficult to differentiate based upon morphological features. In this study, mosquitoes collected from two Illinois counties, Coles County and Champaign County, were first identified based upon morphology and this identification was then compared to probe-based …

Teachers' Perception Of Mental Health In The School System, Nicholas Caldwell

Masters Theses

The study examined teachers' perceptions of their school's mental health system. Specifically, teachers were asked about their role in the identification process, how effective their school's system is at identifying and treating mental health problems, and their suggestions for improvement. Mental health problems affect a significant portion of today's youth (Merikangas et al., 2010). Mental health problems can negatively impact an adolescent's academic achievement, social relationships, and behavioral functioning (Woodward & Fergusson, 2001). Six teachers from a southeastern, rural Illinois high school participated in the study. Each teacher participated in a single interview and discussed their perceptions of the school's …

Detection Of Beta-Lactamase Variants In Municipal Wastewater And Fresh Water, Sunil Pandey

Masters Theses

The occurrence and spread of antibiotic-resistant genes (ARGs) are pressing public health problems worldwide. A key factor contributing to the spread of ARGs is lateral gene transfer. Wastewater treatment plants (WWTPs) are measured hot spots of microbial diversity and resistance because they receive polluted wastewater from diverse sources and contain a variety of different environments with dense bacterial loads. Due to the overuse of antibiotics the genetic capacities of microbes have profited. This helps every source of resistance gene and every means of horizontal gene transmission to develop the multiple mechanism of resistance to each antibiotic used clinically, agriculturally, or …

Support From Above The Glass Ceiling: Narratives Of Women As University Student Leaders, Rebecca Schwartz

Masters Theses

Using qualitative methodology. the researcher examined motivations, social support networks, and challenges college women face in student leadership positions. Four semi-structured interviews were conducted at a midsized university in the Midwest with college women in various positions of organizational leadership. The researcher identified motivational factors for women to apply for leadership positions as well as described the social support network that exists for college women in positions of leadership. Challenges college women face in achieving higher leadership positions were also identified. Lastly, recommendations were made for student affairs professionals and women in leadership based on the research findings.

College Students Experiences Participating In International Alternative Break Trips, Dayton L. Ehrlich

Masters Theses

This study sought to explore undergraduate students’ experiences participating in international alternative break trips. A qualitative approach was used to understand the motivating factors as well as the impact the trip had on them. Participants included three female undergraduate students who had participated in an international alternative break trip in Mexico were interviewed one-on-one. The results demonstrated there were multiple different motivating factors and impacts the students experienced. The motivating factors consisted of student involvement, they were all personally invited on the trip, practicing a new language, opportunity to leave the country, and service was not a motivator. The impacts …

Construct Validity Of The Teate Depression Inventory (Tdi) With A Middle Eastern/Arab American Sample, Dalia Bunni

Masters Theses

The purpose of the study was to examine the construct validity of a newer test used to measure depressive symptoms, the Teate Depression Inventory (TDI). The primary focus of the study was on Middle Eastern/Arab Americans (ME/AA). Previous research has demonstrated that ethnic minority groups may experience and present internalizing disorders, such as depression and anxiety differently than the majority ethnic group, White/Caucasian (W/C) individuals. Further, research suggests that there is a disparity in mental health care among ethnic minority groups, starting with detecting and diagnosing mental health disorders. Inaccurate detection and diagnoses informs inaccurate treatment, further creating a disparity. …

A Pipeline For Exogenous Gene Expression And Biomass Analysis In Plants, Bijay Bisunke

Masters Theses

Biological pretreatment of biomass is typically required for the production of liquid biofuels, which are viable alternatives to traditional fossil fuels. While traditional thermomechanical pretreatments are effective at helping to deconstruct lignocellulose, they are often expensive and tend to generate environmentally dangerous waste materials. An alternative to traditional pretreatment strategies is biological pretreatment, which has focused on lignocellulose-degrading organisms, such as white-rot fungi. While direct pretreatment of biomass with white-rot fungi has shown great promise, directly expressing functional white-rot fungi genes in plants (i.e. in planta expression) has the potential to be even more efficient because the biomass itself …

Medicinal Properties Of The Araliaceae, With Emphasis On Chemicals Affecting Nerve Cells, Rana Alharbi

Masters Theses

In recent times, medicinal plants have become the focus of scientists and research. However, many have used traditional medicine to take advantage of plant extracts to treat many diseases, especially neurological diseases. Various central nervous system receptors have been shown to associate with plant extracts influencing the pharmacology and in this manner conceivably assuming a role in human sickness and treatment. For instance, extracts from Cussonia paniculata Eckl. & Zeyh targeted several early nervous and mental disease, and Kalopanax pictus has been traditionally used for the treatment of rheumatoidal arthritis, nerve pain and diabetes mellitus.

In the present study, we …

Context Dependency Of Invasion Impacts On The Controllers Of Invasibility In Microstegium Vimineum, Scott Vincent Janis

Masters Theses

Although plant invasions are of major conservation concern, understanding of the natural controls on invasion and their impacts is largely limited to static observational studies or artificially manipulated systems. Linking patterns of invasion with subsequent impacts in natural systems is necessary to fully assess invasion causes and consequences. Therefore, I employed a long-term approach to sequentially assess the controls on invasion and their subsequent impacts in a self-assembled system for the highly invasive annual grass Microstegium vimineum. I modeled likely factors contributing to the probability of invasion and local invasion success of a natural invasion of M. vimineum in a …

Assessment And Recovery Of Stream Restoration Efforts On Fish Communities, Jessica Marie Rohr

Masters Theses

Aquatic systems are subjected to disturbances of various types, including natural and anthropogenic, or can deteriorate due to accumulating unfavorable conditions, including receding banks, decreasing riparian vegetation, and disrupted flow patterns. An analysis was done on a variety of streams in central Illinois that experienced one or multiple anthropogenic disturbances without remediation to determine the natural recovery dynamics of each system. A separate analysis was performed on a multi-site restored stream with a complex restoration project with a variety of restoration methods. This data were collected over at periods of time spanning from 5-15 years, including time prior to disturbance/restoration …

Impacts Of Plant-Microbe Interactions On Seedling Performance In A Riparian Forest Invaded By Lonicera Maackii, Taylor E. K. Strehl

Masters Theses

Soil microbes have profound impacts on plant growth and survival and can either promote or inhibit plant dominance. Exotic plants are often strongly invasive because they have escaped their natural enemies, potentially including antagonistic soil microbes. I examined how the invasive shrub Lonicera maackii and a common native tree, Acer negundo, responded to soil microbial communities to determine the role of soil microbes in regulating invasion success. This was done by growing both species with microbes from invaded (L. maackii) and uninvaded (A. negundo) soils collected from three locations within a riparian forest. Seedlings were …
