Effects Of Response Elaboration Training On Sentence Production Of Persons With Chronic Agrammatic Aphasia, Ryan S. Husak

Theses and Dissertations--Rehabilitation Sciences

Purpose: Response Elaboration Training (RET) is a treatment program for increasing the amount of information contained in the speech of individuals with aphasia. This study employed a sentence production task (SPT) to examine whether RET will (1) generalize to a task not worked on in treatment and (2) affect syntactic performance.

Methods and Procedures: Three adults with chronic non-fluent Broca’s aphasia received RET in this prospective, repeated case study. The dependent variable was a SPT requiring the participant to put a verb in a sentence. Changes in the syntactic performance of the participant’s sentence productions were classified across …

A Shared Gene Expression Signature In Mouse Models Of Ebv-Associated And Non-Ebv-Associated Burkitt Lymphoma, Kathryn T. Bieging, Kamonwan Fish, Subbarao Bondada, Richard Longnecker

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The link between EBV infection and Burkitt lymphoma (BL) is strong, but the mechanism underlying that link has been elusive. We have developed a mouse model for EBV-associated BL in which LMP2A, an EBV latency protein, and MYC are expressed in B cells. Our model has demonstrated the ability of LMP2A to accelerate tumor onset, increase spleen size, and bypass p53 inactivation. Here we describe the results of total gene expression analysis of tumor and pretumor B cells from our transgenic mouse model. Although we see many phenotypic differences and changes in gene expression in pretumor B cells, the transcriptional …

Microglial P38Α Mapk Is Critical For Lps-Induced Neuron Degeneration, Through A Mechanism Involving Tnfα, Bin Xing, Adam D. Bachstetter, Linda J. Van Eldik

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: The p38α MAPK isoform is a well-established therapeutic target in peripheral inflammatory diseases, but the importance of this kinase in pathological microglial activation and detrimental inflammation in CNS disorders is less well understood. To test the role of the p38α MAPK isoform in microglia-dependent neuron damage, we used primary microglia from wild-type (WT) or p38α MAPK conditional knockout (KO) mice in co-culture with WT cortical neurons, and measured neuron damage after LPS insult.

RESULTS: We found that neurons in co-culture with p38α-deficient microglia were protected against LPS-induced synaptic loss, neurite degeneration, and neuronal death. The involvement of the proinflammatory …

Driving Qi With Research: Findings From Public Health Pbrns, Glen P. Mays

Health Management and Policy Presentations

Public health agencies are increasingly experimenting with quality improvement (QI) strategies designed to enhance the effectiveness and efficiency of their efforts. Does QI work in public health, and if so for whom and under what circumstances? What QI strategies work best for which types of public health process failures, and at what cost? Research underway through the Public Health Practice-Based Research Networks (PBRN) Program is examining these types of questions to build an evidence base for public health QI.

Physical Therapy Faculty Publications

Dosage for the galvanic stimulation for iontophoresis varies. Clinicians manipulate the duration or the amplitude of the current, but it is not known which is more effective. We compared the anesthetic effect of lidocaine HCL (2%) by manipulating the current parameters on 21 healthy volunteers (age: 21.2 ± 4.2, height 170.7 ± 10.2 cm, mass 82.1 ± 19.2 kg). Three conditions were administered in a random order using a Phoresor II^® with 2 mL, 2% lidocaine HCL in an iontophoresis electrode. (1) HASD (40 mA_*min): High amplitude (4 mA), short duration (10 min); (2) LALD (40 mA.min): …

Maternal Separation Affects Dopamine Transporter Function In The Spontaneously Hypertensive Rat: An In Vivo Electrochemical Study, Jacqueline S. Womersley, Jennifer H. Hsieh, Lauriston A. Kellaway, Greg A. Gerhardt, Vivienne A. Russell

Neuroscience Faculty Publications

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a developmental disorder characterised by symptoms of inattention, impulsivity and hyperactivity. The spontaneously hypertensive rat (SHR) is a well-characterised model of this disorder and has been shown to exhibit dopamine dysregulation, one of the hypothesised causes of ADHD. Since stress experienced in the early stages of life can have long-lasting effects on behaviour, it was considered that early life stress may alter development of the dopaminergic system and thereby contribute to the behavioural characteristics of SHR. It was hypothesized that maternal separation would alter dopamine regulation by the transporter (DAT) in ways that distinguish SHR …

Comparison Of Hip And Knee Strength And Neuromuscular Activity In Subjects With And Without Patellofemoral Pain Syndrome, Lori Ann Bolgla, Terry R. Malone, Brian R. Umberger, Timothy L. Uhl

Physical Therapy Faculty Publications

Purpose/Background: Historically, patellofemoral pain syndrome (PFPS) has been viewed exclusively as a knee problem. Recent findings have suggested an association between hip muscle weakness and PFPS. Altered neuromuscular activity about the hip also may contribute to PFPS; however, more limited data exist regarding this aspect. Most prior investigations also have not concurrently examined hip and knee strength and neuromuscular activity in this patient population. Additional knowledge regarding the interaction between hip and knee muscle function may enhance the current understanding of PFPS. The purpose of this study was to compare hip and knee strength and electromyographic (EMG) …

Widespread Regulation Of Mirna Biogenesis At The Dicer Step By The Cold-Inducible Rna-Binding Protein, Rbm3, Julie Pilotte, Esther E. Dupont-Versteegden, Peter W. Vanderklish

Physical Therapy Faculty Publications

MicroRNAs (miRNAs) play critical roles in diverse cellular events through their effects on translation. Emerging data suggest that modulation of miRNA biogenesis at post-transcriptional steps by RNA-binding proteins is a key point of regulatory control over the expression of some miRNAs and the cellular processes they influence. However, the extent and conditions under which the miRNA pathway is amenable to regulation at posttranscriptional steps are poorly understood. Here we show that RBM3, a cold-inducible, developmentally regulated RNA-binding protein and putative protooncogene, is an essential regulator of miRNA biogenesis. Utilizing miRNA array, Northern blot, and PCR methods, we observed that over …

Liposomal, Ring-Opened Camptothecins With Prolonged, Site-Specific Delivery Of Active Drug To Solid Tumors, Bradley D. Anderson, Vijay Joguparthi, Tiang-Xiang Xiang

Pharmaceutical Sciences Faculty Patents

A method for preparing a stable dispersion of a camptothecin, camptothecin prodrug, or analog thereof for administration to a patient in need thereof includes preparing a solution of the camptothecin, wherein the solution has a pH which places substantially an entirety of that camptothecin in a carboxylate form. The camptothecin may be a neutral camptothecin. The solution is next loaded into a liposome including at least one lipid, which may be a phospholipid. An intraliposomal pH is maintained which preserves substantially an entirety of the camptothecin in the carboxylate form. The liposomal dispersion is administered to an individual in need …

Autoimmune Enteropathy With A Cd8+ Cd7- T-Cell Small Bowel Intraepithelial Lymphocytosis: Case Report And Literature Review, Shrinivas Bishu, Violeta Arsenescu, Eun Y. Lee, H. David Vargas, Willem J. S. De Villiers, Razvan Arsenescu

Surgery Faculty Publications

Background

Adult onset autoimmune enteropathy (AIE) is a rare condition characterized by diarrhea refractory to dietary therapy diagnosed in patients with evidence of autoimmune conditions. Auto-antibodies to gut epithelial cells and other tissues are commonly demonstrated. Despite increasing awareness, the pathogenesis, histologic, immunologic and clinical features of AIE remain uncertain. There remains controversy regarding the diagnostic criteria, the frequency and types of auto-antibodies and associated autoimmune conditions, and the extent and types of histologic and immunologic abnormalities. CD4+ T-cells are thought to at least responsible for this condition; whether other cell types, including B- and other T-cell subsets are involved, …

Exploration And Comparison Of Methods For Combining Population- And Family-Based Genetic Association Using The Genetic Analysis Workshop 17 Mini-Exome, David W. Fardo, Anthony R. Druen, Jinze Liu, Lucia Mirea, Claire Infante-Rivard, Patrick Breheny

Biostatistics Faculty Publications

We examine the performance of various methods for combining family- and population-based genetic association data. Several approaches have been proposed for situations in which information is collected from both a subset of unrelated subjects and a subset of family members. Analyzing these samples separately is known to be inefficient, and it is important to determine the scenarios for which differing methods perform well. Others have investigated this question; however, no extensive simulations have been conducted, nor have these methods been applied to mini-exome-style data such as that provided by Genetic Analysis Workshop 17. We quantify the empirical power and false-positive …

The Science Of Public Health Delivery: Evidence, Uncertainties & Research Needs, Glen P. Mays

Health Management and Policy Presentations

Policy initiatives to reform the nation's health system increasingly recognize the need to incorporate public health and prevention strategies. The nation's delivery system for public health, however, varies widely across states and communities in its structure, authority, and capabilities. This session examines research from the growing field of public health services and systems research to identify directions for improving public health delivery.

Estimating The Value Of Public Health Services & Systems: Evidence, Uncertainties, And Research Needs, Glen P. Mays

Health Management and Policy Presentations

The Affordable Care Act authorized the largest expansion in federal funding for public health services and delivery systems in decades. These provisions, designed to support programs and services that promote health and prevent disease and injury on a population-wide basis, remain controversial because of uncertainties regarding their effectiveness in improving health and constraining medical cost growth. This session examines a series of recent studies to shed light on the health and economic value of spending on public health.

Nanoparticulate Formulations Of Mithramycin Analogs For Enhanced Cytotoxicity, Daniel Scott, Jürgen Rohr, Younsoo Bae

Pharmaceutical Sciences Faculty Publications

Mithramycin (MTM), a natural product of soil bacteria from the Streptomyces genus, displays potent anticancer activity but has been limited clinically by severe side effects and toxicities. Engineering of the MTM biosynthetic pathway has produced the 3-side-chain-modified analogs MTM SK (SK) and MTM SDK (SDK), which have exhibited increased anticancer activity and improved therapeutic index. However, these analogs still suffer from low bioavailability, short plasma retention time, and low tumor accumulation. In an effort to aid with these shortcomings, two nanoparticulate formulations, poly(ethylene glycol)-poly(aspartate hydrazide) self-assembled and cross-linked micelles, were investigated with regard to the ability to load and pH …

Ghrelin Receptor Deficiency Does Not Affect Diet-Induced Atherosclerosis In Low-Density Lipoprotein Receptor-Null Mice, Kirk M. Habegger, Erin Grant, Paul Thomas Pfluger, Diego Perez-Tilve, Alan Daugherty, Dennis Bruemmer, Matthias H. Tschöp, Susanna M. Hofmann

Saha Cardiovascular Research Center Faculty Publications

OBJECTIVE: Ghrelin, a stomach-derived, secreted peptide, and its receptor (growth hormone secretagogue receptor, GHSR) are known to modulate food intake and energy homeostasis. The ghrelin system is also expressed broadly in cardiovascular tissues. Since ghrelin has been associated with anti-inflammatory and anti-atherogenic properties, but is also well known to promote obesity and impair glucose metabolism, we investigated whether ghrelin has any impact on the development of atherosclerosis. The hypothesis that endogenous ghrelin signaling may be involved in atherosclerosis has not been tested previously.

METHODS AND RESULTS: We crossed ghrelin receptor knockout mice (GHSr^-/-) into a low-density lipoprotein receptor-null …

An Evidence-Based Approach To Address Tobacco Dependence Treatment In Mental Health And Addictions Settings, Chizimuzo T.C. Okoli

Nursing Presentations

Purpose: To examine the program completion and smoking cessation outcomes of a tobacco dependence treatment program for individuals with a history of substance use (SUD) and/or psychiatric disorders (PD). Despite the steady decline in the overall smoking prevalence in North America during the last decade some subsets of the population continue to smoke at high rates, particularly individuals with a SUD and/or PD. Among clinical samples, an estimated 75% of individuals with SUD and up to 90% of individuals with PD concurrently smoke. Such findings have prompted the need for tailored tobacco dependence treatment approaches in this population.

Methods: The …
