2010-2019 OA Pubs

GATA4, a transcription factor crucial for early liver development, has been implicated in the pathophysiology of hepatoblastoma, an embryonal tumor of childhood. However, the molecular and phenotypic consequences of GATA4 expression in hepatoblastoma are not fully understood. We surveyed GATA4 expression in 24 hepatoblastomas using RNA in situ hybridization and immunohistochemistry. RNA interference was used to inhibit GATA4 in human HUH6 hepatoblastoma cells, and changes in cell migration were measured with wound healing and transwell assays. RNA microarray hybridization was performed on control and GATA4 knockdown HUH6 cells, and differentially expressed genes were validated by quantitative polymerase chain reaction or …

Hepatic Ketogenic Insufficiency Reprograms Hepatic Glycogen Metabolism And The Lipidome, D. André D'Avignon, Patrycja Puchalska, Baris Ercal, Yingju Chang, Shannon E. Martin, Mark J. Graham, Gary J. Patti, Xianlin Han, Peter A. Crawford

Open Access Publications

While several molecular targets are under consideration, mechanistic underpinnings of the transition from uncomplicated nonalcoholic fatty liver disease (NAFLD) to nonalcoholic steatohepatitis (NASH) remain unresolved. Here we apply multiscale chemical profiling technologies to mouse models of deranged hepatic ketogenesis to uncover potential NAFLD driver signatures. Use of stable-isotope tracers, quantitatively tracked by nuclear magnetic resonance (NMR) spectroscopy, supported previous observations that livers of wild-type mice maintained long term on a high-fat diet (HFD) exhibit a marked increase in hepatic energy charge. Fed-state ketogenesis rates increased nearly 3-fold in livers of HFD-fed mice, a greater proportionate increase than that observed for …

Ursodeoxycholic Acid Versus Phenobarbital For Cholestasis In The Neonatal Intensive Care Unit., Tamorah Lewis, Simisola Kuye, Ashley Sherman

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Although neonates and young infants with cholestasis are commonly treated with either phenobarbital or ursodeoxycholic acid (ursodiol), there is no evidence that phenobarbital is effective for this indication. Our objective was to compare the effectiveness of ursodiol and phenobarbital for the treatment of cholestasis in a diverse NICU population.

METHODS: This is a retrospective cohort study including infants with cholestasis who were admitted to a Level IV NICU between January 2010 and December 2015. Drug courses of phenobarbital and ursodiol were identified within the medical record, and medical, demographic, and drug information were extracted. The primary outcome was reduction …

Preventive Medicine and Environmental Health Faculty Publications

Background: COPD Assessment in Primary Care To Identify Undiagnosed Respiratory Disease and Exacerbation Risk (CAPTURE™) uses five questions and peak expiratory flow (PEF) thresholds (males ≤350 L/min; females ≤250 L/min) to identify patients with a forced expiratory volume in 1 second (FEV₁)/forced vital capacity (FVC)11 60%–80% predicted) who may also benefit from diagnosis and treatment.

Methods: Data from the CAPTURE development study were used to test its sensitivity (SN) and specificity (SP) differentiating mild-to-moderate COPD (n=73) from no COPD (n=87). SN and SP for differentiating all COPD cases (mild to severe; n=259) from those without COPD (n=87) were …

Identification Of A Rhythmic Firing Pattern In The Enteric Nervous System That Generates Rhythmic Electrical Activity In Smooth Muscle, Nick J. Spencer, Timothy J. Hibberd, Lee Travis, Lukasz Wiklendt, Marcello Costa, Hongzhen Hu, Simon J. Brookes, David A. Wattchow, Phil G. Dinning, Damien J. Keating, Julian Sorensen

Open Access Publications

The enteric nervous system (ENS) contains millions of neurons essential for organization of motor behavior of the intestine. It is well established that the large intestine requires ENS activity to drive propulsive motor behaviors. However, the firing pattern of the ENS underlying propagating neurogenic contractions of the large intestine remains unknown. To identify this, we used high-resolution neuronal imaging with electrophysiology from neighboring smooth muscle. Myoelectric activity underlying propagating neurogenic contractions along murine large intestine [also referred to as colonic migrating motor complexes, (CMMCs)] consisted of prolonged bursts of rhythmic depolarizations at a frequency of ∼2 Hz. Temporal coordination of …

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Clinician-rated measures of functioning are often used as primary endpoints in clinical trials and other behavioral research in Huntington disease. As study costs for clinician-rated assessments are not always feasible, there is a question of whether patient self-report of commonly used clinician-rated measures may serve as acceptable alternatives in low risk behavioral trials.

AIM: The purpose of this paper was to determine the level of agreement between self-report and clinician-ratings of commonly used functional assessment measures in Huntington disease.

DESIGN: 486 participants with premanifest or manifest Huntington disease were examined. Total Functional Capacity, Functional Assessment, and Independence Scale assessments …

The Impacts Of Medicaid Expansion On Rural Low-Income Adults: Lessons From The Oregon Health Insurance Experiment., Heidi Allen, Bill J. Wright, Lauren Broffman

Articles, Abstracts, and Reports

Medicaid expansions through the Affordable Care Act began in January 2014, but we have little information about what is happening in rural areas where provider access and patient resources might be more limited. In 2008, Oregon held a lottery for restricted access to its Medicaid program for uninsured low-income adults not otherwise eligible for public coverage. The Oregon Health Insurance Experiment used this opportunity to conduct the first randomized controlled study of a public insurance expansion. This analysis builds off of previous work by comparing rural and urban survey outcomes and adds qualitative interviews with 86 rural study participants for …

Palladin Is A Neuron-Specific Translational Target Of Mtor Signaling That Regulates Axon Morphogenesis, Yusuke Umegaki, Antonio Martínez Brotons, Yui Nakanishi, Zhongyue Luo, Hanlu Zhang, Azad Bonni, Yoshiho Ikeuchi

Open Access Publications

The mTOR signaling pathway regulates protein synthesis and diverse aspects of neuronal morphology that are important for brain development and function. To identify proteins controlled translationally by mTOR signaling, we performed ribosome profiling analyses in mouse cortical neurons and embryonic stem cells upon acute mTOR inhibition. Among proteins whose translation was significantly affected by mTOR inhibition selectively in neurons, we identified the cytoskeletal regulator protein palladin, which is localized within the cell body and axons in hippocampal neurons. Knockdown of palladin eliminated supernumerary axons induced by suppression of the tuberous sclerosis complex protein TSC1 in neurons, demonstrating that palladin regulates …

Boys To Men: Masculinity, Victimization, And Offending, Shon Michael Reed

UNLV Theses, Dissertations, Professional Papers, and Capstones

Male victims are an underrepresented group within society as research within victimology primarily focuses on female victims and services available typically cater to female populations. This study focuses on male victims and draws attention to the role that victimization may play in criminal offending. Prior research has found that male victims may feel a diminished sense of their own masculinity. While other studies have noted that masculinity plays a role in some men’s decisions to engage in criminal behavior (Messerschmidt, 1993, 2016). It seems logical that these two concepts (masculinity and victimization) would be related. Utilizing self-reported data from 135 …

Exacerbation Recovery Patterns In Newly Diagnosed Or Maintenance Treatment-Naïve Patients With Copd: Secondary Analyses Of Ticari 1 Trial Data, David M. Mannino, Emmanuelle M. Clerisme-Beaty, Joanne Franceschina, Naitee Ting, Nancy K. Leidy

This study describes the course of AECOPD in these patients at the time of treatment for the symptoms of acute respiratory tract infection (RTI).

Methods: This study was a secondary analysis of data from a 12-week, randomized clinical trial (TICARI 1) testing the efficacy and safety of once-daily tiotropium 18 µg maintenance therapy versus placebo in newly diagnosed or maintenance treatment-naïve COPD patients with acute RTI symptoms for ≤7 days. Patients received standard care …

Examining Ecological Constraints On The Intergenerational Transmission Of Attachment Via Individual Participant Data Meta-Analysis, Marije L Verhage, R M Pasco Fearon, Carlo Schuengel, Marinus H Van Ijzendoorn, Marian J Bakermans-Kranenburg, Sheri Madigan, Glenn I Roisman, Mirjam Oosterman, Kazuko Y Behrens, Maria S Wong, Sarah Mangelsdorf, Lynn E. Priddis, Karl-Heinz Brisch, Collaboration On Attachment Transmission Synthesis

Research outputs 2014 to 2021

Parents' attachment representations and child-parent attachment have been shown to be associated, but these associations vary across populations (Verhage et al., 2016). The current study examined whether ecological factors may explain variability in the strength of intergenerational transmission of attachment, using individual participant data (IPD) meta-analysis. Analyses on 4,396 parent-child dyads (58 studies, child age 11-96 months) revealed a combined effect size of r = .29. IPD meta-analyses revealed that effect sizes for the transmission of autonomous-secure representations to secure attachments were weaker under risk conditions and weaker in adolescent parent-child dyads, whereas transmission was stronger for older children. Findings …

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Children with acute respiratory tract infections (ARTIs) are prescribed up to 11.4 million unnecessary antibiotic prescriptions annually. Inadequate parent-provider communication is a chief contributor, yet efforts to reduce overprescribing have only indirectly targeted communication or been impractical. This paper describes our multisite, parallel group, cluster randomised trial comparing two feasible interventions for enhancing parent-provider communication on the rate of inappropriate antibiotic prescribing (primary outcome) and revisits, adverse drug reactions and parent-rated quality of shared decision-making, parent-provider communication and visit satisfaction (secondary outcomes).

METHODS/ANALYSIS: We will attempt to recruit all eligible paediatricians and nurse practitioners (currently 47) at an academic …

Parabiosis And Single-Cell Rna Sequencing Reveal A Limited Contribution Of Monocytes To Myofibroblasts In Kidney Fibrosis, Rafael Kramann, Flavia Machado, Haojia Wu, Tetsuro Kusaba, Konrad Hoeft, Rebekka K Schneider, Benjamin D Humphreys

Open Access Publications

Fibrosis is the common final pathway of virtually all chronic injury to the kidney. While it is well accepted that myofibroblasts are the scar-producing cells in the kidney, their cellular origin is still hotly debated. The relative contribution of proximal tubular epithelium and circulating cells, including mesenchymal stem cells, macrophages, and fibrocytes, to the myofibroblast pool remains highly controversial. Using inducible genetic fate tracing of proximal tubular epithelium, we confirm that the proximal tubule does not contribute to the myofibroblast pool. However, in parabiosis models in which one parabiont is genetically labeled and the other is unlabeled and undergoes kidney …

Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

Social rejection is a painful event that often increases aggression. However, the neural mechanisms of this rejection–aggression link remain unclear. A potential clue may be that rejected people often recruit the ventrolateral prefrontal cortex’s (VLPFC) self-regulatory processes to manage the pain of rejection. Using functional MRI, we replicated previous links between rejection and activity in the brain’s mentalizing network, social pain network and VLPFC. VLPFC recruitment during rejection was associated with greater activity in the brain’s reward network (i.e. the ventral striatum) when individuals were given an opportunity to retaliate. This retaliation-related striatal response was associated with greater levels of …

Department of Physical Therapy Faculty Papers

BACKGROUND: Virtual reality and augmented feedback have become more prevalent as training methods to improve balance. Few reports exist on the benefits of providing trunk motion visual feedback (VFB) during treadmill walking, and most of those reports only describe within session changes.

RESEARCH QUESTION: To determine whether trunk motion VFB treadmill walking would improve over-ground balance for older adults with self-reported balance problems.

METHODS: 40 adults (75.8 years (SD 6.5)) with self-reported balance difficulties or a history of falling were randomized to a control or experimental group. Everyone walked on a treadmill at a comfortable speed 3×/week for 4 weeks …

Population-Specific Genetic Modification Of Huntington's Disease In Venezuela., Michael J Chao, Kyung-Hee Kim, Jun Wan Shin, Diane Lucente, Vanessa C Wheeler, Hong Li, Jared C Roach, Leroy Hood, Nancy S Wexler, Laura B Jardim, Peter Holmans, Lesley Jones, Michael Orth, Seung Kwak, Marcy E Macdonald, James F Gusella, Jong-Min Lee

Articles, Abstracts, and Reports

Modifiers of Mendelian disorders can provide insights into disease mechanisms and guide therapeutic strategies. A recent genome-wide association (GWA) study discovered genetic modifiers of Huntington's disease (HD) onset in Europeans. Here, we performed whole genome sequencing and GWA analysis of a Venezuelan HD cluster whose families were crucial for the original mapping of the HD gene defect. The Venezuelan HD subjects develop motor symptoms earlier than their European counterparts, implying the potential for population-specific modifiers. The main Venezuelan HD family inherits HTT haplotype hap.03, which differs subtly at the sequence level from European HD hap.03, suggesting a different ancestral origin …

Validation Of A Novel Scoring System For Changes In Skeletal Manifestations Of Hypophosphatasia In Newborns, Infants, And Children: The Radiographic Global Impression Of Change Scale, Michael P Whyte, Kenji P Fujita, Scott Moseley, David D Thompson, William H Mcalister

Open Access Publications

Hypophosphatasia (HPP) is the heritable metabolic disease characterized by impaired skeletal mineralization due to low activity of the tissue-nonspecific isoenzyme of alkaline phosphatase. Although HPP during growth often manifests with distinctive radiographic skeletal features, no validated method was available to quantify them, including changes over time. We created the Radiographic Global Impression of Change (RGI-C) scale to assess changes in the skeletal burden of pediatric HPP. Site-specific pairs of radiographs of newborns, infants, and children with HPP from three clinical studies of asfotase alfa, an enzyme replacement therapy for HPP, were obtained at baseline and during treatment. Each pair was …
