Effects Of Functional Appliances On Pharyngeal Airway Dimensions: A Cone Beam Computed Tomography Study, Melissa K. Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Functional appliances are intended to correct by incremental advancement of the mandible for correction of skeletal Class 11 relationships. Similar in design to functional appliances, mandibular advancing devices (MAD) are used for obstructive sleep apnea (OSA) patients as they increase the size of the airway by drawing the tongue and soft palate forwards, and thus maintain its patency during sleep. It has been shown that significant increases in airway dimensions and decreases in airway resistance were gained in OSA patients while evaluated with a MAD in place. This retrospective study evaluated volumetric, cross-sectional area and linear changes in the …

Profiles Of Drug Endangered Children: Investigation In A Clinical Sample, Imanie Samanmali Wijayaratne

Loma Linda University Electronic Theses, Dissertations & Projects

Despite the increase in children born prenatally exposed to methamphetamine, little is known about the cognitive and neuropsychological outcomes of these children. Research specific to prenatal-methamphetamine exposure is extremely limited and has been primarily restricted to rat studies. This research combined with the few studies examining children prenatally exposed to methamphetamine suggests that methamphetamine-exposure is associated with various cognitive and neuropsychological delays and is impacted by both biological and environmental factors. Given the scarcity of research in this area, the current study used archival data from a psychological assessment clinic to (1) describe the frequency of prenatal methamphetamine-exposure cases, (2) …

The Relationship Of Infant Feeding And Self-Regulation In Pediatric Obesity, Amy Rebecca Beck

Loma Linda University Electronic Theses, Dissertations & Projects

Pediatric overweight and obesity is a growing national epidemic with 15 percent of children ages 6-19 considered obese and at least 22 percent considered overweight. Although there are many suggested causes, treatments, and preventions for this epidemic, a construct that is showing promise in the current literature as a preventive factor against obesity is breastfeeding in infancy. However, the mechanisms by which breastfeeding may impact later childhood weight are unknown. Some of the literature posits the possibility of self-regulation as a key mechanism in the role of breastfeeding in pediatric overweight/obesity. The purpose of this study was to examine the …

The Proliferation Of Theoretical Paradigms Quandary: How One Novice Researcher Used Eclecticism As A Solution, David W. Stinson

The Qualitative Report

When a doctoral student plans to conduct qualitative education research, the aspect of the dissertation that often becomes problematic is determining which theoretical paradigm(s) might frame the study. In this article, the author discusses how he resolved the quandary through eclecticism. The author begins by describing briefly the purpose of his dissertation study, providing a justification for eclecticism in the selection of theories. He follows with a description of the three theories-poststructural theory, critical race theory, and critical theory-that framed his study and discusses briefly the methodology employed. The author concludes with a discussion of likely objections of his study …

Detection Of Merkel Cell Carcinoma Polyomavirus In Mucosal Merkel Cell Carcinoma, Karen N. Wu, Md, Peter A. Mccue, Md, Zi-Xuan Wang, Phd, Agnieszka K. Witkiewicz, Md

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Case Report: A 61-year-old-woman with a past medical history significant for hypertension, bipolar disorder, obstructive sleep apnea and chronic obstructive pulmonary disease presented with diffusive lymphadenopathy suspicious for lymphoma. A lymph node in her right groin was biopsied by fine needle aspiration and showed atypical cells, but was not diagnostic. An excisional biopsy of the 2 x 2 cm lymph node demonstrated metastatic Merkel cell carcinoma (MCC). No skin lesions were detected. A CT scan revealed the presence of a large nasopharyngeal mass that following surgical removal was diagnosed as MCC. Treatment with etoposide and cisplatin and radiation were instituted. …

Cd34 And Alpha-Smooth Muscle Actin Distinguish Cryptogenic Organizing Pneumonia From Secondary Bronchiolitis Obliterans-Organizing Pneumonia, Karen N. Wu, Md, Tajender S. Vasu, Md, John L. Farber, Md

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Secondary bronchiolitis obliterans-organizing pneumonia (BOOP) is a reaction to injury, forming granulation tissue with airspaces. Idiopathic cryptogenic organizing pneumonia (COP) and secondary BOOP are histologically similar. COP has been reported to show increased collagen in the granulation plugs and fewer myofibroblasts and capillaries. Using CD34 for capillaries and alpha-smooth muscle actin for myofibroblasts, we assessed these statins to differentiate COP from secondary BOOP.

The Elucidation Of Metabolic Pathways And Their Improvements Using Stable Optimization Of Large-Scale Kinetic Models Of Cellular Systems, Evgeni V. Nikolaev

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Metabolic engineering of cellular systems to maximize reaction fluxes or metabolite concentrations still presents a significant challenge by encountering unpredictable instabilities that can be caused by simultaneous or consecutive enhancements of many reaction steps. It can therefore be important to select carefully small subsets of key enzymes for their subsequent stable modification compatible with cell physiology. To address this important problem, we introduce a general mixed integer non-linear problem (MINLP) formulation to compute automatically which enzyme levels should be modulated and which enzyme regulatory structures should be altered to achieve the given optimization goal using non-linear kinetic models of relevant …

Consequences Of Recruitmentdecisions And Heterogeneity On Age-Specific Breeding Success In A Long-Lived Seabird, Lise M. Aubry, David N. Koons, Jean Yves Monnat, Emmanuelle Cam

Wildland Resources Faculty Publications

An individual’s age at first reproduction and investment in successive reproductive attempts are involved in mechanisms that can impede somatic repair, resulting in a decline in reproductive abilities with age (reproductive senescence). We used long-term data from the Black-legged Kittiwake, a long-lived seabird, to address the relationship between recruitment age, age-specific breeding success (BS), and reproductive senescence, while accounting for breeding experience and temporal variation in BS. We first detected late-life improvement in BS across all recruitment groups, which we recognized as ‘‘within-generation selection’’ or the selective disappearance of ‘‘frail’’ phenotypes. When such heterogeneity was accurately accounted for, we showed …

Performance Flight Testing Of Small Electric Powered Unmanned Aerial Vehicles, Jon N. Ostler, W. Jerry Bowman, Deryl O. Snyder, Timothy W. Mclain

Faculty Publications

Flight testing methods are developed to find the drag polar for small unmanned aerial vehicles powered by electric motors with fixed-pitch propellers. Wind tunnel testing was used to characterize the propeller-motor efficiency. The drag polar was constructed using data from flight tests. This drag polar was then used to find the following performance parameters: maximum velocity, minimum velocity, velocity for maximum range, velocity for maximum endurance, maximum rate of climb, maximum climb angle, minimum turn radius, maximum turn rate, and maximum bank angle. The developed flight testing methods are used to characterize the performance of a small UAV.

Assessment Of The Reliability Of The Diagnosis Of Chagas Disease By Indigenous Promotores Of The Amazon Basin In Ecuador, Summer Nguyen

Undergraduate Medical Student Research

Chagas disease, caused by the protozoan parasite, Trypanosoma cruzi, is the most important vector-borne disease in Latin America. It is estimated that 16 to 18 million people are infected with Chagas disease and some 50,000 people die each year. In endemic countries, people living in rural areas are at greatest risk for acquiring infection. Ecuador is one of these countries, and it is estimated that between 2.4-3.8 million people in Ecuador are exposed to Chagas disease, primarily in the Eastern endemic coastal region. The indigenous people of the Amazon region in Ecuador have historically been protected from Chagas disease due …

Tapping In Time: Visual And Auditory Selective Attention In Schizophrenia, Irene Patniyot

Undergraduate Medical Student Research

Attention is a complex construct involving extensive interactions with working memory and executive control systems to process and extract meaning out of large amounts of multi-sensory information. Disruption of attention is a characteristic symptom in schizophrenia, and further studies on selective attention are crucial for understanding the disease. The current study looks at how subjects with schizophrenia selectively attend to either a visual or auditory metronome in the presence of asynchronous cross-modal distractors of 3 different frequencies (0.5, 1, and 2 Hz). Results showed that across all tasks of selective attention, patients with schizophrenia demonstrated increased variability in mean group …

Development Of A Potential Vaccine For Asthma Using Ige And Virus Like Particles, Fernando Monreal, Bryce Chackerian

Undergraduate Medical Student Research

Highly dense, repetitive antigens such as virus particles induce strong immune responses. Correspondingly, Virus Like Particles (VLPs), which consist of the viral structural proteins, can be used as molecular scaffolds to increase the antigenicity of normally poorly immunogenic antigens. This ability to elicit strong antibody responses is not limited to foreign antigens, but also to self-antigens, which are normally subject to B-cell tolerance. The intention of this proposal is to develop a system for rapid identification of asthma vaccine candidates based on potent immunogenicity of antigens (IgE) displayed in dense repetitive arrays on virus-like particles. The technology is based on …

Electrical And Optical Properties Of Carbon Nanotube Intra-Connects And Conductive Polymers, Seon Woo Lee

Dissertations

Growth of individual carbon nanotube (CNT) intra-connects (bridges) between two prefabricated electrodes is a great challenge and a pre-requisite to the development of single electron devices. In this thesis, CNT intra-connects were fabricated and studied. Later on, the intra-connects were deposited with electrically conductive polymer (ECP) in the realization of CNT/ECP hybrids.

The process started by realizing two electrodes with sharp end on a silicon wafer using e-beam lithography. The intra-connects were then grown by use of chemical vapor deposition (CVD) technique. The intra-connects were later electroplated by various conductive polymers. The morphology, electrical conductivity of these intra-connects as well …

Electrohydrodynamic Manipulation Of Multiphase Fluids, Sai C. Nudurupati

Dissertations

In microfluidic devices, the fluid can be manipulated either as continuous streams or droplets. The latter is particularly attractive as individual droplets can not only move but also split and fuse, thus offer a greater flexibility in applications such as a laboratory-on- a-chip. In this thesis, a technique is developed that uses an externally applied electric field for manipulating and removing particles trapped on the surface of a drop. The drop is assumed to be immersed in another liquid with which it is immiscible, and the electric field is generated by placing electrodes on the sides of the microdevice. Both …

Coverage And Payment For Prescription Drugs Under Medicare Part B: A Complex Patchwork, Amanda Cassidy

National Health Policy Forum

As part of the diverse discussions around health care reform, many have looked to refining Medicare payment systems as a way to give health care practitioners and providers greater incentives to deliver care more efficiently, and thus slow health care spending growth. Understanding how Medicare currently pays for Part B services, including drugs covered under Part B, is essential to understanding the potential impact of these types of reforms. Most items and services covered under Part B, including most Part B drugs, are paid individually, which means practitioners and providers generally receive more payments for providing more services. Some reform …
