Enhancing The Relationships Between Students With Emotional And Behavioral Disorders And Their Teachers, Jack Watts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Outcomes of students with emotional and behavioral disorders (EBD) have failed to meet the standards of educators and educational researchers. For several decades, such students have had worse academic and postsecondary outcomes than any other student population. This has led to emphasis on implementation of evidence-based practices to combat the negative outcomes associated with educational diagnoses of EBD (i.e., behavioral outbursts, suspension, and expulsion). Despite this increased attention, little improvement has occurred, leading to the question of whether practices implemented for students with EBD have been addressing the underlying causes of these students’ negative outcomes. Student–teacher relationships could be an …

Understanding Disk Substructures With 3d Self-Consistent Thermodynamics, Shangjia Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Protoplanetary disks are birthplaces of planets. The past decade witnessed a great advance- ment in disk observations by Atacama Large Millimeter Array (ALMA) and extreme adaptive optics (ExAOs). Hundreds of disks have been observed at high angular resolutions and revealed rich substructures (e.g., gaps/rings) at midplane and atmosphere, at least part of which are per- turbed by planets. Deep understanding of disk physics has a great potential to unveil more young planets from substructures and distinguish those that are not caused by planets. I worked on con- straining young planet populations using planet-disk interaction simulations and substructures and self-consistent treatment …

Biopsychosocial Occupational Therapy Interventions For Complex Regional Pain Syndrome – A Pilot Manuscript, Cinthia Hartman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Occupational therapists (OTs) have an essential role in the treatment of upper extremity Complex Regional Pain Syndrome (CRPS) in outpatient therapy settings. Occupational therapy (OT) guidelines and research focus treatment on the Budapest Criteria’s biological signs and symptoms. The International Association for the Study of Pain (IASP) now recognizes CRPS as a primary chronic pain condition and not an autonomic disorder, as it was thought to be in the past. This recognition, along with the psychological and social impacts of the condition, highlight the need for updated OT treatment interventions incorporating a biopsychosocial model. Combining evidence-based CRPS OT interventions for …

A Comparison Of Spinal Reflex Function And Morphological Adaptations Of The Achilles Tendon Between Individuals Chronically Post-Stroke And Healthy Controls, Migi Contreras, Mira Seekins, Johanna Mendez, Trevor Diez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: The hallmark gait deviation in individuals with post-stroke hemiparesis is slow walking speed. Reduction in gait speed after stroke is influenced by decreased propulsive forces, which may likely be related to impaired spinal circuit function and spasticity of the paretic plantarflexors. Chronic muscle tone maladaptations in paretic ankle plantarflexors can result in altered Achilles tendon (AT) morphology, therefore leading to altered mechanical properties, force transmission capabilities and subsequent insufficient propulsive forces during walking. The purpose of this study is to characterize the chronic maladaptations in both the spinal Ia afferent loop excitability and AT morphology after stroke lesions in …

Modulating Cortical Excitability To Improve Functional Movements In Individuals With Patellofemoral Pain: A Randomized Controlled Trial, Jeno Aquino, Bryce Broadwell, Connan Wallace, Makenzie Whimple

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Persons with patellofemoral pain (PFP) often exhibit increased knee valgus during functional tasks that is traditionally addressed by strengthening weak hip musculature. However, research related to this topic has revealed altered cortical reorganization in individuals with PFP contributes to dysfunctional movements and underscores the critical role of central neural control in this condition. Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that alters cortical excitability to enhance neuroplasticity. Research using tDCS priming supports its feasibility as a possible treatment for other musculoskeletal conditions. However, its application specifically targeting the corticomotor function of the gluteal musculature in individuals with …

A Low Dose Of Electro-Psychedelic Treatment Increases Neuronal Dendritic Arborization And Filopodic Spine Density, Elaine Aquino Vasquez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Neuropsychiatric disorders remain a formidable challenge to the global healthcare system, necessitating innovative treatments to address their complex pathophysiology. Alternative therapeutic approaches, including electroconvulsive treatment (ECT) and psychedelics, have gained attention for their capacity to relieve a broad range of symptoms. ECT is a long-standing effective therapy for patients, especially treatment-resistant ones. Psychedelics, like psilocybin, can induce profound and sustained therapeutic effects. The limited understanding of their mechanisms of action, compounded by the negative stigma surrounding ECT and psilocybin, prevents them from being used as adjunct agents. ECT and psilocybin promote synaptic plasticity and modulate neural remodeling, yet their comparative …

Pediatric Trauma-Informed Care And Implications For Occupational Therapy Practitioners, Quaneka Hoskin-Chase

UNLV Theses, Dissertations, Professional Papers, and Capstones

Occupational therapy practitioners are provided a wealth of knowledge through school and professional fieldwork experiences to understand and skillfully address the needs of children who have been exposed to trauma. Therapists are competently prepared to provide holistic and client-centered care that is dedicated to meaningful and volitional engagement (Lynch et al., 2021). However, many therapists still lack the confidence and awareness of their role related to trauma-informed care in the pediatric environment (Piller, 2022). Trauma compromises each domain of occupation (Lynch et al., 2021). As early intervention specialists, the lack of responsiveness to children’s trauma can have devastating and enduring …

Characterizing The Molecular And Cellular Changes Of Senescent Cells Induced By Diverse Stressors In 2d And 3d Microenvironments, Apoorva Chauhan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Aging is a risk factor for myriad diseases and is often associated with the accumulation of senescent cells. Cellular senescence, a process of irreversible cell cycle arrest, is associated with various changes in cellular morphology and function. While senescence will occur naturally in a time-dependent manner, it can be prematurely induced by various extrinsic and intrinsic factors. Most senescence studies model cell behavior in two-dimensional (2D) microenvironments; however, these models are not physiologically relevant. In this study, the effects of naturally occurring reactive oxygen species (ROS) hydrogen peroxide (H2O2) and commonly used chemotherapy drugs, doxorubicin and palbociclib, on cellular senescence …

Regulation Of Embryonic Eye Regrowth In Xenopus Laevis, Dylan Guerin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Regrowth of lost organs and tissues is an amazing ability that some animals possess. For regrowth to be considered full, the organism must regrow the organ or tissue to a state that is structurally and functionally similar to that which was lost. The ability of an organism to regrow lost or damaged tissue varies among animals, both in the mechanisms utilized to achieve regrowth, and in what body parts can be regrown. Potentially even closely related species can vary wildly in regenerative ability. Therefore, regenerative research can look to other tissues and organisms for direction in elucidating the mechanisms through …
