Alpha-1 antitrypsin deficiency is a monogenic disorder resulting in emphysema due principally to the unopposed effects of neutrophil elastase. We previously reported achieving plasma wild-type alpha-1 antitrypsin concentrations at 2.5%-3.8% of the purported therapeutic level at 1 year after a single intramuscular administration of recombinant adeno-associated virus serotype 1 alpha-1 antitrypsin vector in alpha-1 antitrypsin deficient patients. We analyzed blood and muscle for alpha-1 antitrypsin expression and immune cell response. We also assayed previously reported markers of neutrophil function known to be altered in alpha-1 antitrypsin deficient patients. Here, we report sustained expression at 2.0%-2 ...

Audiology Students’ Perception Of Hybrid Simulation Experiences: Qualitative Evaluation Of Debriefing Sessions, Ahmad A. Alanazi, Nannette Nicholson, Samuel R. Atcherson, Clifford A. Franklin, Naveen K. Nagaraj, Michael Anders, Laura Smith-Olinde

Journal of Early Hearing Detection and Intervention

Simulation-based research is still new in the audiology field and requires more research to better understand students’ perspectives on standardized patients/parents (SPs) and manikins use. There is also limited research about debriefing practices in audiology. This qualitative study used a baby simulator and SPs to evaluate audiology students’ reflection during three debriefing sessions conducted at the University of Arkansas for Medical Science (UAMS) Simulation Center. Seventeen Doctor of Audiology (AuD) students participated in the simulation event, and the data were collected using the transcripts of videotaped debriefing sessions. The qualitative content analysis of the transcripts revealed eight sub-themes: support ...


Persistent Neurobehavioral Traits In A Mouse Model Of Prenatal Ethanol Exposure, Jill M. Lawrence 2017 Ursinus College

Persistent Neurobehavioral Traits In A Mouse Model Of Prenatal Ethanol Exposure, Jill M. Lawrence

Neuroscience Honors Papers

Fetal Alcohol Spectrum Disorders (FASD) effect an estimated 2% of the population, causing a range of symptoms: from craniofacial defects to inhibited cortical growth (May, et al., 2009; Murawski, et al., 2015). Impaired medial forebrain function apparent in FASD is associated with lifelong cognitive behavioral deficits, but these consequences may be avoided with early diagnosis and intervention (Streissguth, et al., 2004). Our goal is to identify early neurobehavioral abnormalities that persist into adulthood that could potentially serve as early indicators for FASD. Mouse models of prenatal ethanol exposure were developed using a voluntary drinking paradigm that introduced a sweetened ethanol ...

Open Access Articles

OBJECTIVE: To examine the therapeutic potential of stochastic vibrotactile stimulation (SVS) as a complementary non-pharmacological intervention for withdrawal in opioid-exposed newborns. STUDY DESIGN: A prospective, within-subjects single-center study was conducted in 26 opioid-exposed newborns ( > 37 weeks; 16 male) hospitalized since birth and treated pharmacologically for Neonatal Abstinence Syndrome. A specially-constructed mattress delivered low-level SVS (30-60Hz, 10-12mum RMS), alternated in 30-min intervals between continuous vibration (ON) and no vibration (OFF) over a 6-8 hr session. Movement activity, heart rate, respiratory rate, axillary temperature and blood-oxygen saturation were calculated separately for ON and OFF. RESULTS: There was a 35% reduction in movement ...

High Throughput In Vivo Functional Validation Of Candidate Congenital Heart Disease Genes In Drosophila., Jun-Yi Zhu, Yulong Fu, Margaret Nettleton, Adam Richman, Zhe Han

Pediatrics Faculty Publications

Genomic sequencing has implicated large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system is needed to validate gene associations with pathology. We developed a Drosophila-based functional system to screen candidate disease genes identified from Congenital Heart Disease (CHD) patients. 134 genes were tested in the Drosophila heart using RNAi-based gene silencing. Quantitative analyses of multiple cardiac phenotypes demonstrated essential structural, functional, and developmental roles for more than 70 genes, including a subgroup encoding histone H3K4 modifying proteins. We also demonstrated the use of Drosophila to evaluate cardiac phenotypes resulting ...


Promotion Of Early Pediatric Hearing Detection Through Patient Navigation, Matthew L. Bush 2017 University of Kentucky

Promotion Of Early Pediatric Hearing Detection Through Patient Navigation, Matthew L. Bush

Theses and Dissertations--Clinical and Translational Science

Congenital hearing loss is the most common neonatal sensory disorder and it is crucial to diagnose hearing loss as soon as possible after birth in order to facilitate rapid treatment. Universal standards of infant hearing healthcare dictate that infant hearing screening should be completed by one month of age and abnormal screening tests should be followed with definitive audiological testing by three months of age. Obtaining diagnostic testing can be complicated by limited access to care in rural areas, breakdowns in communication, lack of parental support, and poor coordination of care. There is no established method to address appointment non-adherence ...


Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts 2017 The University of Akron

Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts

Honors Research Projects

Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.

Objectives: To evaluate the use of biomarkers in children seen in the Emergency ...

Abnormal Glycosylation In Joubert Syndrome Type 10., Megan S Kane, Mariska Davids, Michelle R Bond, Christopher J Adams, Megan E Grout, Ian G Phelps, Gilbert Vezina, +Several Additional Authors

Neurology Faculty Publications

BACKGROUND: The discovery of disease pathogenesis requires systematic agnostic screening of multiple homeostatic processes that may become deregulated. We illustrate this principle in the evaluation and diagnosis of a 5-year-old boy with Joubert syndrome type 10 (JBTS10). He carried the OFD1 mutation p.Gln886Lysfs*2 (NM_003611.2: c.2656del) and manifested features of Joubert syndrome.

METHODS: We integrated exome sequencing, MALDI-TOF mass spectrometry analyses of plasma and cultured dermal fibroblasts glycomes, and full clinical evaluation of the proband. Analyses of cilia formation and lectin staining were performed by immunofluorescence. Measurement of cellular nucleotide sugar levels was performed with high-performance anion-exchange ...


Novel Roles Of Adhesion G Protein-Coupled Receptors In Cardiovascular Development, Andrew Poggemiller 2017 University of Iowa

Novel Roles Of Adhesion G Protein-Coupled Receptors In Cardiovascular Development, Andrew Poggemiller

University of Iowa Honors Theses

Congenital heart disease is the most common congenital birth defect, affecting 1.35 million newborns every year. Though therapeutic techniques have been developed to assist those afflicted, new issues arise as those that have been treated may have a higher likelihood to pass on their cardiovascular defect to their children. Adhesion G protein-coupled receptors are an increasingly studied member of the G protein-coupled receptor superfamily. aGPCRs have a wide array of molecular mechanisms that it affects; however, their role in the development of organ systems, specifically the cardiovascular system, is the focus of our research. When screening for aGPCRs within ...


Histone Deacetylase 3 Coordinates Heart Development Through Stage-Specific Roles In Cardiac Progenitor Cells, Sara L. Lewandowski 2016 University of Massachusetts Medical School

Histone Deacetylase 3 Coordinates Heart Development Through Stage-Specific Roles In Cardiac Progenitor Cells, Sara L. Lewandowski

GSBS Dissertations and Theses

Disruptions in cardiac development cause congenital heart disease, the most prevalent and deadly congenital malformation. Genetic and environmental factors are thought to contribute to these defects, however molecular mechanisms remain largely undefined. Recent work highlighted potential roles of chromatin- modifying enzymes in congenital heart disease pathogenesis. Histone deacetylases, a class of chromatin-modifying enzymes, have developmental importance and recognized roles in the mature heart. This thesis aimed to characterize functions of Hdac3 in cardiac development. We found loss of Hdac3 in the primary heart field causes precocious progenitor cell differentiation, resulting in hypoplastic ventricular walls, ventricular septal defect, and mid- gestational ...

Losing Ground: Awareness Of Congenital Cytomegalovirus In The United States, Sara M. Doutre, Tyson S. Barrett, Janelle Greenlee, Karl R. White

Journal of Early Hearing Detection and Intervention

One in 150 infants is born with cytomegalovirus (CMV) and one in 750 will have lifelong disabilities due to CMV. Even though congenital CMV is the leading viral cause of congenital disabilities and the leading non-genetic cause of childhood hearing loss, most adults have never heard of it. Data from the 2015 and 2016 HealthStylesTM surveys were analyzed and compared to data from similar studies and show an awareness rate of 7% for US adults (5% for men and 9% for women), a statistically significant decrease from 2005 and 2010 studies. Predictors of awareness include gender and education level ...


Native T1 Values Identify Myocardial Changes And Stratify Disease Severity In Patients With Duchenne Muscular Dystrophy., Laura J. Olivieri, Peter Kellman, Robert J. McCarter, Russell R. Cross, Michael S. Hansen, Christopher F. Spurney 2016 George Washington University

Native T1 Values Identify Myocardial Changes And Stratify Disease Severity In Patients With Duchenne Muscular Dystrophy., Laura J. Olivieri, Peter Kellman, Robert J. Mccarter, Russell R. Cross, Michael S. Hansen, Christopher F. Spurney

Pediatrics Faculty Publications

BACKGROUND: Duchenne muscular dystrophy (DMD) is an X-linked, inherited disorder causing dilated cardiomyopathy with variable onset and progression. Currently we lack objective markers of the effect of therapies targeted towards preventing progression of subclinical cardiac disease. Thus, our aim was to compare the ability of native T1 and extracellular volume (ECV) measurements to differentiate risk of myocardial disease in DMD and controls.

METHODS: Twenty boys with DMD and 16 age/gender-matched controls without history predisposing to cardiac fibrosis, but with a clinical indication for cardiovascular magnetic resonance (CMR) evaluation, underwent CMR with contrast. Data points collected include left ventricular ejection ...

In Vivo Correction Of Anaemia In Beta-Thalassemic Mice By Gammapna-Mediated Gene Editing With Nanoparticle Delivery, Raman Bahal, Dale L. Greiner, Michael A. Brehm, Peter M. Glazer

Open Access Articles

The blood disorder, beta-thalassaemia, is considered an attractive target for gene correction. Site-specific triplex formation has been shown to induce DNA repair and thereby catalyse genome editing. Here we report that triplex-forming peptide nucleic acids (PNAs) substituted at the gamma position plus stimulation of the stem cell factor (SCF)/c-Kit pathway yielded high levels of gene editing in haematopoietic stem cells (HSCs) in a mouse model of human beta-thalassaemia. Injection of thalassemic mice with SCF plus nanoparticles containing gammaPNAs and donor DNAs ameliorated the disease phenotype, with sustained elevation of blood haemoglobin levels into the normal range, reduced reticulocytosis, reversal ...

A premature termination codon (PTC) in the ORF of an mRNA generally leads to production of a truncated polypeptide, accelerated degradation of the mRNA, and depression of overall mRNA expression. Accordingly, nonsense mutations cause some of the most severe forms of inherited disorders. The small-molecule drug ataluren promotes therapeutic nonsense suppression and has been thought to mediate the insertion of near-cognate tRNAs at PTCs. However, direct evidence for this activity has been lacking. Here, we expressed multiple nonsense mutation reporters in human cells and yeast and identified the amino acids inserted when a PTC occupies the ribosomal A site in ...

Neurology Faculty Publications

BACKGROUND: Mutations in the RMND1 (Required for Meiotic Nuclear Division protein 1) gene have recently been linked to infantile onset mitochondrial disease characterised by multiple mitochondrial respiratory chain defects.

METHODS: We summarised the clinical, biochemical and molecular genetic investigation of an international cohort of affected individuals with RMND1 mutations. In addition, we reviewed all the previously published cases to determine the genotype-phenotype correlates and performed survival analysis to identify prognostic factors.

RESULTS: We identified 14 new cases from 11 pedigrees that harbour recessive RMND1 mutations, including 6 novel variants: c.533C>A, p.(Thr178Lys); c.565C>T, p.(Gln189*); c ...


Activation Of Target Gene Expression In Neurons By The C. Elegans Rfx Transcription Factor, Daf-19, Katherine P. Mueller 2016 Lawrence University

Activation Of Target Gene Expression In Neurons By The C. Elegans Rfx Transcription Factor, Daf-19, Katherine P. Mueller

Lawrence University Honors Projects

DAF-19, the only RFX transcription factor found in C. elegans, is required for the formation of neuronal sensory cilia. Four isoforms of the DAF-19 protein have been reported, and the m86 nonsense (null) mutation affecting all four isoforms has been shown to prevent cilia formation. Transcriptome analyses employing microarrays of L1 and adult stage worms were completed using RNA from daf-19(m86) worms and an isogenic wild type strain to identify additional putative DAF-19 target genes. Using transcriptional fusions with GFP, we compared the expression patterns of several potential gene targets using fluorescence confocal microscopy. Expression patterns were characterized in ...

Alpha-1 antitrypsin (AAT) deficiency is a common monogenic disorder resulting in emphysema, which is currently treated with weekly infusions of protein replacement. We previously reported achieving plasma wild-type (M) AAT concentrations at 2.5-3.8% of the therapeutic level at 1 year after intramuscular (IM) administration of 6×1012vg/kg of a recombinant adeno-associated virus serotype 1 (rAAV1)-AAT vector in AAT-deficient patients, with an associated regulatory T cell (Treg) response to AAV1 capsid epitopes in the absence of any exogenous immune suppression. Here, we report sustained expression at greater than 2% of the therapeutic level for 5 years after ...
