Spinocerebellar ataxia type 1 (SCA1) is a fatal neurodegenerative disease caused by an expanded polyglutamine tract in the widely expressed ataxin-1 (ATXN1) protein. To elucidate anatomical regions and cell types that underlie mutant ATXN1-induced disease phenotypes, we developed a floxed conditional knockin mouse (f-ATXN1146Q/2Q) with mouse Atxn1 coding exons replaced by human ATXN1 exons encoding 146 glutamines. f-ATXN1146Q/2Q mice manifested SCA1-like phenotypes including motor and cognitive deficits, wasting, and decreased survival. Central nervous system (CNS) contributions to disease were revealed using f-ATXN1146Q/2Q;Nestin-Cre mice, which showed improved rotarod, open field, and Barnes maze performance by 6-12 weeks of age. In contrast, …

The Disordered N-Terminal Tail Of Sars-Cov-2 Nucleocapsid Protein Forms A Dynamic Complex With Rna, Jasmine Cubuk, Jhullian J Alston, J Jeremías Incicco, Alex S Holehouse, Kathleen B Hall, Melissa D Stuchell-Brereton, Andrea Soranno

2020-Current year OA Pubs

The SARS-CoV-2 Nucleocapsid (N) protein is responsible for condensation of the viral genome. Characterizing the mechanisms controlling nucleic acid binding is a key step in understanding how condensation is realized. Here, we focus on the role of the RNA binding domain (RBD) and its flanking disordered N-terminal domain (NTD) tail, using single-molecule Förster Resonance Energy Transfer and coarse-grained simulations. We quantified contact site size and binding affinity for nucleic acids and concomitant conformational changes occurring in the disordered region. We found that the disordered NTD increases the affinity of the RBD for RNA by about 50-fold. Binding of both nonspecific …

Faculty Publications

Injuries and subclinical effects from exposure to blasts are of significant concern in military operational settings, including tactical training, and are associated with self-reported concussion-like symptomology and physiological changes such as increased intestinal permeability (IP), which was investigated in this study. Time-series gene expression and IP biomarker data were generated from “breachers” exposed to controlled, low-level explosive blast during training. Samples from 30 male participants at pre-, post-, and follow-up blast exposure the next day were assayed via RNA-seq and ELISA. A battery of symptom data was also collected at each of these time points that acutely showed elevated symptom …

INTRODUCTION: People with aphasia following stroke experience disproportionally poor outcomes, yet there is no comprehensive approach to measuring the quality of aphasia services. The Meaningful Evaluation of Aphasia SeRvicES (MEASuRES) minimum dataset was developed in partnership with people with lived experience of aphasia, clinicians and researchers to address this gap. It comprises sociodemographic characteristics, quality indicators, treatment descriptors and outcome measurement instruments. We present a protocol to pilot the MEASuRES minimum dataset in clinical practice, describe the factors that hinder or support implementation and determine meaningful thresholds of clinical change for core outcome measurement instruments. METHODS AND ANALYSIS: This research …

Journal of Human Services Scholarship and Interprofessional Collaboration

Young adults with serious mental illness (SMI) experience disproportionate rates of physical illness. Morbidity and mortality are even worse for young African Americans with SMI, especially those who are overweight. Primary care physicians (PCPs) have an important role in addressing weight management. Current research explored these young patient’s perceptions of weight management and how PCPs can best address their weight concerns. Using community-based participatory research, we interviewed 25 African American aged 18-30 who were overweight and had a SMI. Results revealed 1) patient perceptions around weight and 2) patient preferences. Participants identified both positive and negative aspects of being overweight, …

Ai-Driven Solutions Promote Medication Adherence, Eric Pulice, Alberto Coustasse

Management Faculty Research

A study conducted in 2019 showed that approximately 50% of the 187 million patients in the US health care system did not follow their medication plan as prescribed. This means they failed to adhere to the drug regimen or to take the medication for the entire prescribed duration. Adherence rates for most medications used to treat chronic conditions, such as diabetes and hypertension, usually fall in the range of 50% to 60%, even with patients who have good insurance and drug benefits. This rate of adherence leads to an estimated 125,000 avoidable deaths each year and $100 billion annually in …

Effects Of Maternal-Infant Golden Hour On Breastfeeding, Julina A. Wall-Penner, Katilyn Rasmussen, Madeline Suderman

SACAD: Scholarly Activities

Abstract

This study examines the effects of immediate maternal-infant skin-to-skin contact, and how those effects compare to mothers and babies who have delayed or skin-to-skin. Skin-to-skin contact, also known as “the golden hour”, is a remarkable practice that occurs immediately after birth. During this intimate bonding experience, the newborn is placed directly on the mother's chest, their tiny body nestled against her warm skin. Studies have shown numerous benefits from this practice. Breastfeeding success through early initiation is one the benefits this study focuses on. This cohort observational study is recommended to take place at Hays Medical Center with mothers …

Epitope Mapping Of Japanese Encephalitis Virus Neutralizing Antibodies By Native Mass Spectrometry And Hydrogen/Deuterium Exchange, Jagat Adhikari, James Heffernan, Melissa Edeling, Estefania Fernandez, Prashant N Jethva, Michael S Diamond, Daved H Fremont, Michael L Gross

2020-Current year OA Pubs

Japanese encephalitis virus (JEV) remains a global public health concern due to its epidemiological distribution and the existence of multiple strains. Neutralizing antibodies against this infection have shown efficacy in in vivo studies. Thus, elucidation of the epitopes of neutralizing antibodies can aid in the design and development of effective vaccines against different strains of JEV. Here, we describe a combination of native mass spectrometry (native-MS) and hydrogen/deuterium exchange mass spectrometry (HDX-MS) to complete screening of eight mouse monoclonal antibodies (MAbs) against JEV E-DIII to identify epitope regions. Native-MS was used as a first pass to identify the antibodies that …

The Latissimus Dorsi Creates A Dynamic Track For The Inferior Angle Of The Scapula During Arm Abduction In Humans, Alp Paksoy, Doruk Akgün, Henry Gebauer, Daniel Karczewski, Lucca Lacheta, John M Tokish, Aaron Chamberlain, Philipp Moroder

2020-Current year OA Pubs

BACKGROUND: The importance of several scapulothoracic muscles, including trapezius and serratus anterior, in maintaining physiological scapula kinematics has been highlighted in the past. However, the relationship between the scapula and the latissimus dorsi muscle remains unclear. Our clinical surgical observation is that the latissimus dorsi does not directly attach but rather runs superficial to the inferior angle of the scapula. Based on this observation, we hypothesise that the latissimus dorsi creates a dynamic track on which the scapula glides under the muscle belly during elevation of the arm, creating the latissimus-scapula overlap (LSO).

METHODS: All consecutive patients who had a …

Garza, Major Extremity Trauma Research Consortium (Metrc)

Physical Therapy Faculty Articles and Research

In persons with limb loss, prosthetic devices cause skin breakdown, largely because residual limb skin (nonvolar) is not intended to bear weight such as palmoplantar (volar) skin. Before evaluation of treatment efficacy to improve skin resiliency, efforts are needed to establish normative data and assess outcome metric reliability. The purpose of this study was to use optical coherence tomography to (i) characterize volar and nonvolar skin epidermal thickness and (ii) examine the reliability of optical coherence tomography. Four orientations of optical coherence tomography images were collected on 33 volunteers (6 with limb loss) at 2 time points, and the epidermis …

Effects Of Stroboscopic Vision On Depth Jump Motor Control: A Biomechanical Analysis, Kenneth D. Harrison, Christopher J. Dakin, Anne Z. Beethe, Talin Louder

Kinesiology and Health Science Faculty Publications

Researchers commonly use the 'free-fall' paradigm to investigate motor control during landing impacts, particularly in drop landings and depth jumps (DJ). While recent studies have focused on the impact of vision on landing motor control, previous research fully removed continuous visual input, limiting ecological validity. The aim of this investigation was to evaluate the effects of stroboscopic vision on depth jump (DJ) motor control. Ground reaction forces (GRF) and lower-extremity surface electromyography (EMG) were collected for 20 young adults (11 male; 9 female) performing six depth jumps (0.51 m drop height) in each of two visual conditions (full vision vs. …

Understanding Heterogeneity In Individual Responses To Digital Lifestyle Intervention Through Self-Monitoring Adherence Trajectories In Adults With Overweight Or Obesity: Secondary Analysis Of A 6-Month Randomized Controlled Trial, Shiyu Li, Yan Du, Hongyu Miao, Kumar Sharma, Chengdong Li, Zenong Yin, Bradley Brimhall, Jing Wang

Faculty, Staff and Student Publications

Background: Achieving clinically significant weight loss through lifestyle interventions for obesity management is challenging for most individuals. Improving intervention effectiveness involves early identification of intervention nonresponders and providing them with timely, tailored interventions. Early and frequent self-monitoring (SM) adherence predicts later weight loss success, making it a potential indicator for identifying nonresponders in the initial phase.

Objective: This study aims to identify clinically meaningful participant subgroups based on longitudinal adherence to SM of diet, activity, and weight over 6 months as well as psychological predictors of participant subgroups from a self-determination theory (SDT) perspective.

Methods: This was a secondary data …

Pediatric Beta Blocker Therapy: A Comprehensive Review Of Development And Genetic Variation To Guide Precision-Based Therapy In Children, Adolescents, And Young Adults., Mollie Walton, Jonathan B. Wagner

Manuscripts, Articles, Book Chapters and Other Papers

Beta adrenergic receptor antagonists, known as beta blockers, are one of the most prescribed medications in both pediatric and adult cardiology. Unfortunately, most of these agents utilized in the pediatric clinical setting are prescribed off-label. Despite regulatory efforts aimed at increasing pediatric drug labeling, a majority of pediatric cardiovascular drug agents continue to lack pediatric-specific data to inform precision dosing for children, adolescents, and young adults. Adding to this complexity is the contribution of development (ontogeny) and genetic variation towards the variability in drug disposition and response. In the absence of current prospective trials, the purpose of this comprehensive review …

While excessive production of reactive oxygen species (ROS) is a characteristic hallmark of numerous diseases, clinical approaches that ameliorate oxidative stress have been unsuccessful. Here, utilizing multi-omics, we demonstrate that in cardiomyocytes, mitochondrial isocitrate dehydrogenase (IDH2) constitutes a major antioxidative defense mechanism. Paradoxically reduced expression of IDH2 associated with ventricular eccentric hypertrophy is counterbalanced by an increase in the enzyme activity. We unveil redox-dependent sex dimorphism, and extensive mutual regulation of the antioxidative activities of IDH2 and NRF2 by a feedforward network that involves 2-oxoglutarate and L-2-hydroxyglutarate and mediated in part through unconventional hydroxy-methylation of cytosine residues present in introns. …

Summit-Fa: A New Resource For Improved Transcriptome Imputation Using Functional Annotations, Hunter J Melton, Zichen Zhang, Chong Wu

Faculty, Staff and Student Publications

Transcriptome-wide association studies (TWAS) integrate gene expression prediction models and genome-wide association studies (GWAS) to identify gene-trait associations. The power of TWAS is determined by the sample size of GWAS and the accuracy of the expression prediction model. Here, we present a new method, the Summary-level Unified Method for Modeling Integrated Transcriptome using Functional Annotations (SUMMIT-FA), which improves gene expression prediction accuracy by leveraging functional annotation resources and a large expression quantitative trait loci (eQTL) summary-level dataset. We build gene expression prediction models in whole blood using SUMMIT-FA with the comprehensive functional database MACIE and eQTL summary-level data from the …

Physical Activity Barriers And Facilitators In African American Women: A Social Ecological Models Perspective, Leah Ann Carter

LSU Doctoral Dissertations

African American (AA) women experience poor health outcomes that can be addressed by increasing PA engagement. Understanding how PA barriers and facilitators occur at multiple levels of influence may help tailor PA interventions for AA women. Although prior work has established barriers to PA that are unique to African American women, few studies identify the sociocultural norms associated with these impediments. Little is known about the cultural implications of barriers such as haircare maintenance, and public policy.

The primary aim of this dissertation was to capture AA women’s voice about PA barriers and facilitators using the social ecological model framework. …

A Tough Bioadhesive Hydrogel Supports Sutureless Sealing Of The Dural Membrane In Porcine And Ex Vivo Human Tissue, Kyle C Wu, Benjamin R Freedman, Phoebe S Kwon, Matthew Torre, Daniel O Kent, Wenya Linda Bi, David J Mooney

Duncan NRI Faculty and Staff Publications

Complete sequestration of central nervous system tissue and cerebrospinal fluid by the dural membrane is fundamental to maintaining homeostasis and proper organ function, making reconstruction of this layer an essential step during neurosurgery. Primary closure of the dura by suture repair is the current standard, despite facing technical, microenvironmental, and anatomic challenges. Here, we apply a mechanically tough hydrogel paired with a bioadhesive for intraoperative sealing of the dural membrane in rodent, porcine, and human central nervous system tissue. Tensile testing demonstrated that this dural tough adhesive (DTA) exhibited greater toughness with higher maximum stress and stretch compared with commercial …

Investigating The Roles And Responsibilities Of Institutional Signing Officials After Data Sharing Policy Reform For Federally Funded Research In The United States: National Survey, Jinyoung Baek, Jonathan Lawson, Vasiliki Rahimzadeh

Center for Medical Ethics and Health Policy Staff Publications

Background: New federal policies along with rapid growth in data generation, storage, and analysis tools are together driving scientific data sharing in the United States. At the same, triangulating human research data from diverse sources can also create situations where data are used for future research in ways that individuals and communities may consider objectionable. Institutional gatekeepers, namely, signing officials (SOs), are therefore at the helm of compliant management and sharing of human data for research. Of those with data governance responsibilities, SOs most often serve as signatories for investigators who deposit, access, and share research data between institutions. Although …
