Thyroid Lymphoma As A Cause Of Dysphagia And Dyspnea In A Patient Without Palpable Nodules Or Goiter, Jarrod D. Frizzell, Brandon J. Perkins, R. Scott Morehead

Internal Medicine Faculty Publications

Tumors originating in the neck are well-known causes of progressive dysphagia and dyspnea (including stridor), and thyroid lymphoma is an uncommon example. Physical examination provides an important first step in the evaluation of such complaints, as tumors large enough to produce such symptoms are typically considered to be palpable, if not able to be seen grossly. In this case presentation, the authors describe a nonsubsternal thyroid lymphoma measuring 3 x 4 cm at its largest diameter, producing dysphagia and leading to respiratory emergency, that was entirely nonpalpable to physical exam even after confirmation of its presence by computed tomography.

Control Of Myosin Motor Activity And Actin Filament Translation By Alteration Of Assay Reducing Potential, Siva Krishna Nalabotu

Theses, Dissertations and Capstones

The use of biomolecular motors for nanotechnological applications has been impaired by an inability to control biomolecular motor activity in a temporal fashion. Previous data has suggested that myosin activity can be modulated by inducing changes in the degree of myosin oxidation. The hypothesis of this study is that myosin motor activity can be regulated by altering the amount of antioxidants and reducing agents present in assay solution. To test this hypothesis we systematically altered the concentration of reducing agents and examined the effects of these changes on myosin-dependent actin filament translation. Our findings indicate that myosin activity can be …

Concepts Of Contraception For Adolescents With Obesity: Pathways Of Judicial Moderation, Donald E. Greydanus, Hatim A. Omar, Artemis Tsitsika

Pediatrics Faculty Publications

All sexually active youth, whether obese or normal weight, should be offered counseling regarding contraception and appropriate contraceptive methods. However, obese youth who are sexually active may be less likely than their normal weight peers to use contraceptives correctly. Methods of contraception for obese adolescents are reviewed in this discussion. Combined oral contraceptives (COCs) and the contraceptive patch have higher failure rates in obese versus normal weight females, though failure rates are lower than noted with barrier contraceptives. The risk for venous thrombosis is higher in obese youth on COCs. Progestin-only pills and the levonorgestrel intrauterine system appear to be …

Psychological And Social Development, Kimberly K. Mcclanahan, Marlene B. Huff, Hatim A. Omar

Pediatrics Faculty Publications

The global epidemic of childhood and adolescent overweight has become a major public health concern. Not only are these youth more likely to become obese as adults, and thus more prone to obesity-related diseases than their non overweight peers, they are also likely to suffer emotional and social effects associated with overweight. Overweight in youth has been linked to depression, low self-esteem, eating disorders, negative body image, and stigma. It appears to be bi-directional in nature, with overweight sometimes predicting certain psychological effects and psychosocial issues sometimes predicting overweight. Effective assessment and treatment of psychological and mental health issues in …

Quality Of Life, Environmental Domain, And Use Of Identification Devices In Nursing, William L. Rhoads

Master's Theses or Doctor of Nursing Practice

Significant attention has been brought to the safety of medical and nursing care in acute-care hospitals, but nursing homes are not immune to errors that result in injury (Kapp, 2003). Errors, even minor ones, can have significant impact in this population group of aged, frail individuals (Scott-Cawiezell, et al., 2006). Nursing home residents do not wear an identification device for varied reasons. This places an extra burden on those passing medications to ensure they have the right person receiving the right medication. The purpose of this study was to determine the relationships between variables with the resident’s willingness to wear …

Studies On Drug Solubilization Mechanism In Simple Micelle Systems, Shaoxin Feng

University of Kentucky Doctoral Dissertations

Poor aqueous solubilities of drug candidates limit the biopharmaceutical usefulness in either oral or parenteral dosage forms. Lipid assemblies, such as micelles, may provide a means of enhancing solubility. Despite their usefulness, little is known about the means by which micelles accomplish this result. The goal of the current dissertation is to provide the molecular level understanding of the mechanism by which simple micelle systems solubilize drugs. Specifically, the location, orientation and amount of the drug molecules in micelle systems are the focuses of the work.

Three series of model drugs, steroids, benzodiazepines and parabens, in three surfactant systems with …

Experimental And Molecular Dynamics Simulation Studies Of Partitioning And Transport Across Lipid Bilayer Membranes, Ravindra Wadhumal Tejwani

University of Kentucky Doctoral Dissertations

Most drugs undergo passive transport during absorption and distribution in the body. It is desirable to predict passive permeation of future drug candidates in order to increase the productivity of the drug discovery process. Unlike drug-receptor interactions, there is no receptor map for passive permeability because the process of transport across the lipid bilayer involves multiple mechanisms. This work intends to increase the understanding of permeation of drug-like molecules through lipid bilayers.

Drug molecules in solution typically form various species due to ionization, complexation, etc. Therefore, species specific properties must be obtained to bridge the experiment and simulations. Due to …

Roles Of Emx2 In Odorant Receptor Gene Expression And Olfactory Sensory Neuron Axon Growth, Jeremy Colin Mcintyre

University of Kentucky Doctoral Dissertations

The sense of smell relies upon the detection of odorants by neurons located in the nasal cavity. These neurons, referred to as olfactory sensory neurons (OSNs), line the olfactory epithelium and extend axons that make synaptic connections with mitral/tufted cells in the olfactory bulb. The mechanisms by which these synaptic connections form remain largely unknown. The development of these synaptic connections relies on the axons of immature OSNs innervating the olfactory bulb. The primary goal of this dissertation was to identify components of the mechanisms used by immature OSN axons to innervate the olfactory bulb. To accomplish this goal, a …

Role Of Oxidative Stress And T Cell Homing In The Development Of Murine Syngeneic Graft-Versus-Host Disease, Jacqueline Perez-Rodriguez

University of Kentucky Doctoral Dissertations

Syngeneic graft-versus-host disease (SGVHD) is induced by reconstituting lethally irradiated mice with syngeneic BM cells followed by a 21 day treatment with the immunosuppressive agent cyclosporine A (CsA). Clinical symptoms of the disease appear 2-3 weeks following cessation of CsA therapy and disease-associated inflammation occurs primarily in the colon and liver.

The development of SGVHD is a complex process resulting from the cooperative interaction of multiple effector cell populations including NK cells, T cells and macrophages. T_H1 cytokines (IL-12, TNF-α, IFN- γ), produced by these effector cells, serve as inflammatory mediators contributing to the pathogenesis of SGVHD. The …

Pathogenesis Of Influenza A Virus: Inhibition Of Monocyte Differetiation Into Dendritic Cell, Saikat Boliar

University of Kentucky Doctoral Dissertations

Dendritic cells (DC) are a heterogeneous population of hematopoietic cells that play a versatile role in orchestrating immune responses against an array of invading pathogens, including influenza virus. These cells reside in lymphoid organs as well as in non-lymphoid tissues such as mucosal surfaces of respiratory and gastro-intestinal system. Recent investigations have suggested that in the steady state, dendritic cells are derived mainly from bone marrow precursor cells without a monocytic intermediate whereas during inflammation or infection, monocytes readily differentiate to generate monocyte derived dendritic cells (MoDC). The ability of virus infected monocytes to differentiate into MoDC was investigated and …

Methods: A purposive sampling technique was used to identify study participants (n = 32) from the United States (n = 16) and Iceland (n = 16). Data were collected via a semi …

Culture And The Social Context Of Health Inequalities, Carol Leler Mansyur, Benjamin C. Amick Iii, Luisa Franzini, Robert E. Roberts

Community & Environmental Health Faculty Publications

There is a great deal of recent interest and debate concerning the linkages between inequality and health cross-nationally. The U.S. National Institutes of Health recommended in 2001 that any new research on health disparities should include social and cultural systems as units of analysis. Nevertheless, many public health interventions and policies continue to decontextualize risk factors from the social environment. Exposures to social and health inequalities probably vary as a consequence of different cultural contexts. To identify the processes that cause social and health inequalities, it is important to understand culture's influence. Navarro's research on political institutions and inequality illustrates …

Probing The Urea Dependence Of Residual Structure In Denatured Human Α-Lactalbumin, Victoria A. Higman, Heike I. Rösner, Raffaella Ugolini, Lesley H. Greene, Christina Redfield, Lorna J. Smith

Chemistry & Biochemistry Faculty Publications

Backbone ¹⁵N relaxation parameters and ¹⁵N–¹H^N residual dipolar couplings (RDCs) have been measured for a variant of human α-lactalbumin (α-LA) in 4, 6, 8 and 10 M urea. In the α-LA variant, the eight cysteine residues in the protein have been replaced by alanines (all-Ala α-LA). This protein is a partially folded molten globule at pH 2 and has been shown previously to unfold in a stepwise non-cooperative manner on the addition of urea. ¹⁵N R₂ values in some regions of all-Ala α-LA show significant exchange broadening which is reduced as the urea …

Ellmer School of Nursing Faculty Publications

The author reflects on direct to consumer advertising which is concerned with erectile dysfunction drugs. She suggests that many people have problems with open discussions of sexual health problems. She argues that urologic nurses should have discussions with pharmaceutical representatives about ways to responsibly educate the public about erectile dysfunction drugs in a manner that is not offensive.

The Effects Of Visual Representations On Teacher Training Of Phonological Awareness Principles, Rachel Kennedy Powell

LSU Doctoral Dissertations

Teachers are now being held to high accountability standards in reading instruction, yet studies show that teachers lack adequate knowledge in reading and phonological awareness principles (Moats, 1994, 2009; Spencer, Schuele, Guillot, & Lee, 2008). The purpose of this study was to determine the effects of visual representations of letter/sound production (i.e., Phonic Faces, Norris, 2001) on improving teacher knowledge of phonological awareness principles, and to determine if there is a concomitant improvement in phonological awareness and reading acquisition for children in those classrooms. Seventeen kindergarten teachers from a Mississippi school were pretested on phonological awareness principles, then divided into …

Tumor Necrosis Factor Induced Oxidative Stress In The Central Nervous System Contributes To Sympathoexcitation In Heart Failure, Anuradha Guggilam

LSU Doctoral Dissertations

Despite advanced therapeutic strategies for post-myocardial infarction (MI) patients, many ultimately develop congestive heart failure (CHF), rendering the disease a major cause of death in the United States. MI is associated with an acute increase in sympathetic nervous system activity, becoming persistent in CHF patients. Increased pro-inflammatory cytokines (PICs) following MI are implicated in the pathogenesis of CHF. The increase in tumor necrosis factor (TNF), a primary PIC, correlates closely with heart disease severity. Moreover, central PIC production increases post-MI, and can affect the brain’s cardiovascular regulatory regions that control sympathoexcitation. Therefore, understanding how PICs modulate sympathoexcitation is important for …

Matrix Metalloproteinases In The Equine Systemic Inflammatory Response: Implications For Equine Laminitis, Lee Ann Fugler

LSU Doctoral Dissertations

Laminitis is a crippling and often life-threatening disease of the equine foot. Soft tissue damage characteristic of this disease has been associated with increased MMP activity. Therefore, it seems likely that MMPIs could be potential therapeutic agents for laminitis. Further characterization of equine MMPs and evaluation of the effectiveness of MMPIs in the horse are needed. Equine MMP-9 was harvested from neutrophils, purified by affinity chromatography, and evaluated using western blotting and gelatin zymography. The Biotrak MMP-9 Activity Assay was evaluated for use with equine samples using equine neutrophil MMP-9 as a standard, and was determined to have insufficient sensitivity …

Improving Follow-Up Of Abnormal Cancer Screens Using Electronic Health Records: Trust But Verify Test Result Communication, Hardeep Singh, Lindsey Wilson, Laura A Petersen, Mona K Sawhney, Brian Reis, Donna Espadas, Dean F Sittig

Faculty, Staff and Student Publications

BACKGROUND: Early detection of colorectal cancer through timely follow-up of positive Fecal Occult Blood Tests (FOBTs) remains a challenge. In our previous work, we found 40% of positive FOBT results eligible for colonoscopy had no documented response by a treating clinician at two weeks despite procedures for electronic result notification. We determined if technical and/or workflow-related aspects of automated communication in the electronic health record could lead to the lack of response.

METHODS: Using both qualitative and quantitative methods, we evaluated positive FOBT communication in the electronic health record of a large, urban facility between May 2008 and March 2009. …

An Introduction To Dezert-Smarandache Theory (Dsmt), Jean Dezert, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

The management and combination of uncertain, imprecise, fuzzy and even paradoxical or highly conflicting sources of information has always been, and still remains today, of primal importance for the development of reliable modern information systems involving artificial reasoning. In this introduction, we present a survey of our recent theory of plausible and paradoxical reasoning, known as Dezert-Smarandache Theory (DSmT), developed for dealing with imprecise, uncertain and conflicting sources of information. We focus our presentation on the foundations of DSmT and on its most important rules of combination, rather than on browsing specific applications of DSmT available in literature. Several simple …

Optimizing Computer-Aided Colonic Polyp Detection For Ct Colonography By Evolving The Pareto Front, Jiang Li, Adam Huang, Jack Tao, Jiamin Liu, Robert L. Van Uitert, Nicholas Petrick, Ronald Summers

Electrical & Computer Engineering Faculty Publications

A multiobjective genetic algorithm is designed to optimize a computer-aided detection (CAD) system for identifying colonic polyps. Colonic polyps appear as elliptical protrusions on the inner surface of the colon. Curvature-based features for colonic polyp detection have proved to be successful in several CT colonography (CTC) CAD systems. Our CTC CAD program uses a sequential classifier to form initial polyp detections on the colon surface. The classifier utilizes a set of thresholds on curvature-based features to cluster suspicious colon surface regions into polyp candidates. The thresholds were previously chosen experimentally by using feature histograms. The chosen thresholds were effective for …
