A Systematic Literature Review On Alternative Treatment Modalities In Adults With Treatment Resistant Depression, Brian Miller

Epsilon Sigma at-Large Research Conference

Abstract

            Currently, Psychiatric Mental Health Nurse Practitioners (PMHNPs) often defer to electroconvulsive therapy (ECT) for individuals with TRD who fail to achieve resolution of their disorder. However, many individuals do not meet criteria for ECT or decline the treatment due to side effects and associated risks. To synthesize potential alternative treatments and address the current gap in literature that does not include first-line preferred electroconvulsive therapy (ECT), a systematic literature review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA 2020). Databases searched for this review included the Cumulative Index to Nursing and Allied Health Literature …

Choreographed Confession: Plath’S Engineered Extremity And Technical Voice, Emma Heagney

Liberty University Research Week

Sylvia Plath’s poetry is frequently interpreted through the framework of confessionalism, encouraging readings that equate emotional extremity with spontaneous self-disclosure and psychological crisis. This presentation challenges that assumption by arguing that the intensity of Plath’s late poetry is not an eruption of uncontrolled feeling but a deliberately engineered aesthetic effect. Drawing on Plath’s journals and letters alongside close readings of poems from Ariel, the project demonstrates that Plath conceived of poetry as a disciplined, technical practice involving control, revision, and precision rather than unmediated expression. Her private writings repeatedly emphasize ordering, manipulation, and the importance of sound, revealing a poet …

A systematic literature review assessed the recent literature on postpartum relapse risk, contributors, and maternal outcomes in women with bipolar disorder. Systematic search of three electronic databases, CINAHL, PubMed, and PsycINFO, revealed 168 studies dating back to 2022. Title and abstract screening of 124 articles was carried out after elimination of duplicates and other eligibility criteria. Eighteen articles were full-text reviewed, and …

Adolescent Depression, Telepsychiatry, And Access, Dustin Strickland

Epsilon Sigma at-Large Research Conference

Adolescent depression is prevalent, undertreated, and associated with long-term morbidity if left untreated. Several structural barriers impede timely access to specialty mental health care in this age group. Telepsychiatry, including therapist delivered videoconference psychotherapy and internet delivered cognitive behavioral therapies (ICBT) have been developed to expand access and continuity of care for adolescents. This modality, however, has not been thoroughly evaluated to determine the effectiveness of telepsychiatry in improving access to services and its ability to reduce depressive symptoms in adolescence. A structured literature review identified six primary studies and four complementary systematic reviews evaluating this topic. Randomized trials show …

“Slaves To Sin:” Harnessing Neuroplasticity To Defeat Habitual Behaviors, Charity Parrott

Liberty University Research Week

How does neuroplasticity affect the life of a Christian? This thesis will seek to address the concepts of habit formation, neuroplasticity, and top-down control through a neurobiological perspective, and how they relate to the Biblical concept of habitual sin. Discoveries in neuroplasticity have revealed the brain to be a malleable organ, capable of rewiring neural connections and, in the hippocampus region, neurogenesis, or the creation of new neurons (Fuchs & Flügge, 2014). This thesis will compile research in neuroplasticity, explore the biological reasons behind the difficulty in escaping patterns of sin, and connect Biblical-based strategies for sin prevention with neurobiology. …

Formation Of Rosette-Like Hierarchical Structures On Cylindrical Titanium Surfaces., Cole Urquhart, Ally Doud, Michael Korn, Hector Medina

Liberty University Research Week

The purpose of this experiment was to characterize titanium-based rosettes and other micro-sized crystal formations on multiple different non-planar titanium surfaces. Rosettes are crystal structures in the titanium sulfate family. They are 20-150µm in diameter and vastly increase the surface area of the places where they are grown, which can lead to various possible applications in future research. The titanium type that was being experimented on was titanium gauze (50µm diameter). To grow titanium-based structures, two steps are involved: etching and crystal formation. Firstly, the titanium material was placed in a centrifuge tube filled with 1mL of 18M (96%) conc. …

Comparison Of Hypothalamic And Hippocampal Neurogenesis Across Sexes And Ages Of Mice, Chloe Jensen, Madison Reynolds, Rebecca Kinyon

Liberty University Research Week

Background: The hippocampus is primarily known for its function in learning and memory; thus, it makes sense that this is a well-established highly neurogenic zone. Recent studies have demonstrated that the hypothalamus also has neurogenic properties where there were once believed to be none. Because of these recent findings, our study aims to provide baseline data pertaining to rates of neurogenesis in the hypothalamus in comparison to the hippocampus along with distinguishing differences in these rates between males and females. Methods: Using four mice, three young and one aged female, we cryosectioned the brain to image the hippocampal and hypothalamic …

Pilot Study: Black Tea Extract And Theaflavin Polyphenols Effects On L6 Myotubes, Elizabeth Allen

Liberty University Research Week

This research investigates bioactive polyphenol group theaflavins found in black tea and how they affect Akt signaling in skeletal muscle. The black tea polyphenols are a collection of innate compounds in Camillia sinensis, among them being the theaflavin group which is comprised of four compounds: theaflavin (TF1), theaflavin 3-gallate (TF2A), theaflavin 3’-gallate (TF2B), and theaflavin 3,3’ digallate (TF3) (He, 2017). The theaflavins group has been described as bioactive in a variety of different cellular pathways such as apoptosis, cellular division, gene expression and nutrient regulation (Li et al., 2021)(He, 2017)(Lin et al., 2007).

Increasing Fatigue Life: Position And Energy Controlled Surface Mechanical Attrition Treatment, Joseph Holt

Liberty University Research Week

Metal structures in engineering are limited by mechanical fatigue. When a material is repeatedly stressed, even beneath its ultimate strength, it slowly develops nano-fractures that propagate and eventually cause the material to suddenly fracture or fail. When this occurs in high-precision, cyclically stressed applications, such as commercial airliners, unchecked material fatigue is catastrophic. This study has shown promising increases in weld-site material fatigue life through a newly developed processing method. Researchers at Liberty University’s Center for Engineering Research and Education (CERE) custom-built a machine to perform position and energy controlled surface mechanical attrition treatment (PECSMAT), which harnesses the advantages of …

Authentic Vs. Artificial Intelligence: The Effect Of Generative Ai On Users’ Brains, Ivy Rath

Liberty University Research Week

Currently, research on generative AI's effect on the brains of those who use it is sparse. However, cognitive offloading, or the outsourcing of intellectual processes to technology or other people, is a well-known neurological phenomenon, and it is through cognitive offloading that we may begin to understand how generative AI affects mental processes. Cognitive offloading occurs frequently, and common examples include using a calculator, GPS, or driver-assist functions. Now, generative AI offers users a far more pervasive kind of cognitive offloading, in that entire mental processes once unique to human minds (such as problem-solving) may now be replicated and supplanted …

Effect Of In-Utero Exposure To A Western-Style Diet On Testis Development, Alexa Ashby, Colton Fitzgerald, Kaylee Vis, Madison Ashby, Marisa Halsey, Nathan Malina, Ryan Anderson

Liberty University Research Week

The increase in western-style dietary patterns has led to an increase in obesity prevalence and its associated comorbidities. Specifically, researchers have found that obesity due to western-style diet (WSD) is negatively correlated with reproductive health in men. This study investigated the effects of inutero exposure to a WSD on testis development, specifically of 12- week-old mice (young adult C57Bl/6J). We hypothesized that in-utero exposure to a WSD would negatively impact testis development and function in male offspring. Using histological hematoxylin and eosin staining and immunohistochemistry method, we examined spermatogenesis in seminiferous tubules, anti-Mullerian hormone (AMH) production by Sertoli cells, and …

Quantifying Neuropathy With Von Frey Filaments In Mice: Novel Neuropathic Pain Animal Model, Maggie Milhorne

Liberty University Research Week

Neuropathic pain is a chronic pain condition resulting from damage to the nervous system which does not respond to current pharmacological treatments. Previous research in rats has demonstrated that formalin injections can induce chronic pain states and molecular changes within the spinal cord comparable to those of the spinal nerve ligation (SNL), an established surgical model of neuropathic pain. This study aimed to determine whether a subcutaneous injection of 5% formalin is sufficient to induce chronic pain in mice, providing a simple and less invasive model to study chronic pain mechanisms. Mechanical pain sensitivity is assessed using the von Frey …

Single Step Cyanoacrylate Fumigation With Common Dyes, Abigail Proffitt, Jared Filegar

Liberty University Research Week

Cyanoacrylate fumigation is a widely used fingerprint development method to visualize latent fingerprints left on nonporous surfaces. This methodology relies on heating cyanoacrylate, otherwise known as superglue, to create vapors that polymerize onto fingerprints. These vapors react via biological components such as amino acids and other residues left from finger oils. This technique is very effective; however, once the polymer has completed its reaction the fingerprint is colorless resulting in the need for a secondary staining technique. The additional procedure increases processing time and introduces potentials for smearing or human error. This research aims to investigate a way to consolidate …

A Bloody Window To The Past: Str Analysis Of Dna From A Bloodstained Civil War Surgical Table, Nadia Walter

Liberty University Research Week

This study aimed to generate DNA profiles from the bloody Hillsman House surgical table via STR analysis while also determining the best method of sample collection and analysis from a wooden substrate. During the Battle at Sailor’s Creek in 1865, the historical Hillsman House served as a field hospital where hundreds of Civil War soldiers were treated. In 2016, Jones and McClintock collected and analyzed samples from bloodstains on the floorboards of the house, showing that historical DNA is still viable for profiling. During this process, marks on the floorboard were presumed to be from the surgical table, which was …

Regulation Of Glut5 Expression And Fructose Uptake By Heat Stress And Pro-Inflammatory Cytokines In Enterocytes, Landri Shope, Gretchka Mair

Liberty University Research Week

Diabetes is an escalating global health concern, affecting 11.1% of the adult population worldwide, with over 90% of cases classified as type 2 diabetes mellitus (T2DM) (Facts & Figures., n.d.). T2DM is characterized by chronic fasting hyperglycemia and is increasingly associated with alterations in the gut microbiome. This study tests the hypothesis that heat stress, a gut dysbiosis-associated stressor, will upregulate the fructose transporter GLUT5 in enterocytes. Increased GLUT5 expression may enhance intestinal fructose uptake, thereby contributing to worsened glycemic control in T2DM. While the mechanism linking inflammation and impaired glucose homeostasis remains elusive, emerging evidence supports strong associations among …

Forensic Differentiation Of Canine Hair, Allison Kelley

Liberty University Research Week

The goal of this research is to determine whether the characteristics of dog hair can effectively differentiate between canine breeds, which is important for forensic applications. While there is extensive literature on human hair analysis, there is not much to be found on canine hair, although dogs are present at many crime scenes. This research ultimately aims to gather sufficient data on a wide range of dog breeds to compile a comprehensive database to identify differences in dog hair, contributing to the discipline of trace evidence hair analysis within forensic science. The central hypothesis in this study is that specific …
