When Problems Become Solutions: Harnessing The Osteogenic Capacity Of Disease-Causing Stem Cells To Repair Bone Fractures, Mehreen Pasha

University Scholar Projects

While we often perceive disease as negative, there is potential to engineer seemingly negative biological phenomena into therapeutics to treat a variety of human illnesses. Fibrodysplasia ossificans progressiva (FOP) is a genetic disorder involving uncontrolled, widespread, extraskeletal bone growth, or heterotopic ossification (HO). In FOP patients, stem cells called fibro/adipogenic progenitors (FAPs) follow an abnormal, osteogenic pathway. In the present study, we investigate whether we can adapt these Acvr1 mutant FAPs, which are exceptional at producing bone, to repair bone fractures in otherwise normal patients. The primary aims of this study are (1) to devise and optimize a novel method …

Early Detection Of Atypical Motor And Neurobehavior Of Infants At Risk Secondary To Opioid Exposure: A Prospective Study, Kara Boynewicz

Electronic Theses and Dissertations

Prenatal opioid exposure has been studied in relation to infants' medical outcomes. However, large gaps exist in the literature supporting early identification of atypical neurobehavior and motor development of infants with prenatal opioid exposure. The purpose of the study was to investigate whether prenatal opioid exposure has a negative influence on a newborn infant’s neurobehavior and motor development to aid in the early identification of potential delays. Using a prospective quasi experimental design, infants motor development using the Test of Infant Motor Performance (TIMP) and neurobehavior using the NICU Neonatal Network Scale (NNNS) was assessed on 58 infants in a …

The Use Of Spectral Imaging To Reveal Inorganics And Organics Identity In The Biological Samples, Qamar Alshammari

Pharmaceutical Sciences (PhD) Dissertations

The wavelength is used to identify the exact location and quantify the number of molecules in the spectral imaging system. It aids in identifying materials and studying their quantities by examining how they interact with light. A traditional spectrometer provides spectrum information of chemical compounds, while standard imaging provides the intensity at each pixel of the image. Spectral imaging (SI) combines these two aspects by equipping intensity and spectral data for each pixel. In biomedical research, it is important to assess the inorganics/organics molecules to understand drug activity, cellular toxicity, and distribution. Using the microscopy technique, we found for the …

Targeting Metabolic Adaptations To Anti-Angiogenic Therapy In Ovarian Cancer, Deanna M. Glassman, Deanna Glassman

Dissertations & Theses (Open Access)

ABSTRACT

Background: Ovarian cancer is the most lethal gynecologic malignancy. Despite modest clinical improvements with anti-VEGF antibody (AVA) therapy, adaptive resistance is nearly ubiquitous and additional therapeutic options are limited. A dependence on glutamine metabolism, via the enzyme glutaminase (GLS), is a known mechanism of adaptive resistance.

Purpose: To assess the efficacy of a glutaminase inhibitor as a means of exploiting the metabolic vulnerability of glutamine dependence that develops as a result of adaptive resistance to AVA therapy.

Experimental Design: We used a glutaminase inhibitor (GLSi) synthesized at MD Anderson Cancer Center for all in vitro and in vivo experiments. …

Foundations Of Plasmas For Medical Applications, T. Von Woedtke, Mounir Laroussi, M. Gherardi

Electrical & Computer Engineering Faculty Publications

Plasma medicine refers to the application of nonequilibrium plasmas at approximately body temperature, for therapeutic purposes. Nonequilibrium plasmas are weakly ionized gases which contain charged and neutral species and electric fields, and emit radiation, particularly in the visible and ultraviolet range. Medically-relevant cold atmospheric pressure plasma (CAP) sources and devices are usually dielectric barrier discharges and nonequilibrium atmospheric pressure plasma jets. Plasma diagnostic methods and modelling approaches are used to characterize the densities and fluxes of active plasma species and their interaction with surrounding matter. In addition to the direct application of plasma onto living tissue, the treatment of liquids …

Self-Rated Function And Delayed Onset Muscle Soreness (Doms) Responses To 6-Week Supplementation With Waters With Anti-Inflammatory Capabilities (Wac), Kristin Garner

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: Researchers have examined the effects of sedentary lifestyles on diminished health outcomes and are pleading individuals to take on a more active lifestyle to prevent these. However, initial efforts to exercise are often dampened by delayed onset muscle soreness (DOMS) and muscle fatigue. This can greatly reduce exercise adherence, making it difficult for individuals to overcome this temporary discomfort. Background: Research has extensively evaluated nonsteroidal anti-inflammatory drugs (NSAIDs) and fruits as anti-inflammatory supplementation to treat DOMS. Berry-derived essences are more highly concentrated in anti-inflammatory substances than regular fruit juices, but there is minimal research on their effects on exercise …

Analyzing The Survival Rate Of Clinically Pathogenic Bacteria On Occupational Therapy Devices Used During Full Hip Replacement Rehabilitation, Meredith Rippy

Honors Theses

An increasing concern of the healthcare system has been that of Healthcare-Associated Infections (HAIs). HAIs currently account for approximately 1.7 million infections and 99,000 deaths per year in United States hospitals. HAI’s (formerly called nosocomial infections) are defined as infections that develop in patients who have been in residence in a healthcare facility (i.e., in-patient clinics) for 48 hours or longer and who previously had no evidence of infection prior to admission. Consequences of HAIs include increased length of hospital stay, exposure to high frequency antibiotics, sepsis, and in unfortunate cases, death. In out-patient environments where patients are receiving rehabilitative …

Spectroscopic Measurements Of Meibum Compositional, Structural, And Functional Relationships To Elucidate The Role Of Meibum In Dry Eye., Anthony Chigozie Ewurum

Electronic Theses and Dissertations

The major aim of my dissertation was to investigate the etiology of dry eye disease which affects about 7 million people in the United States, causing symptoms that can lead to visual disturbance. Correlation between dry eye and an abnormal lipid layer of the tear film has been found. Tear film lipids originate mostly from the meibomian glands. Cholesteryl ester (CE) and Wax ester (WE) lipids make up most of the human meibum lipidome and the CE/WE ratio has been shown to decrease in patients with meibomian gland dysfunction. Model studies using synthetic CE and WE, although providing some insight, …

Estimating The Analytical Performance Of Raman Spectroscopy For Quantification Of Active Ingredients In Human Stratum Corneum, Hichem Kichou, Emilie Munnier, Yuri Dancik, Kamilia Kemel, Hugh Byrne, Ali Tfayli, Dominique Bertrand, Martin Soucé, Igor Chourpa, Franck Bonnier

Articles

Confocal Raman microscopy (CRM) has become a versatile technique that can be applied routinely to monitor skin penetration of active molecules. In the present study, CRM coupled to multivariate analysis (namely PLSR—partial least squares regression) is used for the quantitative measurement of an active ingredient (AI) applied to isolated (ex vivo) human stratum corneum (SC), using systematically varied doses of resorcinol, as model compound, and the performance is quantified according to key figures of merit defined by regulatory bodies (ICH, FDA, and EMA). A methodology is thus demonstrated to establish the limit of detection (LOD), precision, accuracy, sensitivity (SEN), and …

Using A Food Insecurity Screening Tool In The Nicu, Emily Coffman Bsn, Rn, Fatina Caldwell Bs, Bsn, Rn, Cpn, Cpen, Mackenzie Box Bsn, Rn, Uche Anani Md, Faap, Christin Fritz Md, Mph, Bobby Bellflower Dnsc, Nnp-Bc, Faanp

Doctor of Nursing Practice Projects

Purpose/Background: Infants admitted to the NICU are disproportionately born to low-income families. This, combined with unique financial challenges of their long-term stay, may predispose caregivers to food insecurity (FI). FI among caregivers has far reaching implications for the health of infants who are already vulnerable related to comorbidities from their NICU stay.

Methods: Using the Iowa model to successfully engage key stake holders and begin a small pilot study, a randomized preintervention chart audit was performed (n=30) to evaluate if FI was identified by NICU Social Worker (SW). The FI screening tool was administered by nursing to a separate group …

Advantages Of Early Utilization Of Palliative Care In The Pediatric Icu: A Scoping Review, Shelby Noel Cain Bsn, Rn, Cpn, Dana Pabalate Zimmerman Msn, Rn, Charis Elizabeth Oji Msn, Aprn, Cpnp-Pc/Ac, Michelle Rickard Dnp, Cpnp-Ac

Doctor of Nursing Practice Projects

Abstract Purpose/Background Despite the increased use of palliative care in adults, only a tiny percentage of children with life-limiting illnesses or life-threatening conditions receive palliative care before dying. Palliative care has low utilization, and consults are often made late in a child’s hospitalization or diagnosis. Palliative care remains underutilized among hospitalized pediatric patients resulting in unnecessary treatments, costly and lengthy hospitalizations, and deaths occurring in the intensive care unit (ICU) rather than at home. The purpose of this scoping review is to evaluate current literature to determine the use and effect of pediatric palliative care, specifically, whether consultation of palliative …
