Department of Food Science and Technology: Faculty Publications

Pneumococcal surface protein A (PspA) is a choline-binding protein which is a virulence factor found on the surface of all Streptococcus pneumoniae strains. Vaccination with PspA has been shown to be protective against a lethal challenge with S. pneumoniae, making it a promising immunogen for use in vaccines. Herein, the design of a PspA-based subunit vaccine using polyanhydride nanoparticles as a delivery platform is described. Nanoparticles based on sebacic acid (SA), 1,6-bis-(p-carboxyphenoxy)hexane (CPH) and 1,8-bis-(p-carboxyphenoxy)-3,6- dioxaoctane (CPTEG), specifically 50:50 CPTEG:CPH and 20:80 CPH:SA, were used to encapsulate and release PspA. The protein released from the nanoparticle …

Food, Parasites, And Epidemiological Transitions: A Broad Perspective, Karl Reinhard, Luis Fernando Ferreira, Françoise Bouchet, L. Sianto, J. M.F. Dutra, A. Iniguez, Daniela Leles, M. Le Bailley, Martín Horacio Fugassa, Elisa Pucu, Adauto Araújo

Karl Reinhard Publications

Pathoecology provides unique frameworks for understanding disease transmission in ancient populations. Analyses of Old and New World archaeological samples contribute empirically to our understanding of parasite infections. Combining archaeological and anthropological data, we gain insights about health, disease, and the way ancient people lived and interacted with each other and with their environments. Here we present Old and New World parasite evidence, emphasizing how such information reflects the different ways ancient populations exploited diverse environments and became infected with zoonotic parasites. It is clear that the most common intestinal helminthes (worm endoparasites) were already infecting ancient inhabitants of the New …

Shrinkage Empirical Likelihood Estimator In Longitudinal Analysis With Time-Dependent Covariates: Application To Modeling The Health Of Filipino Children, Denis H. Y. Leung, Dylan S. Small, Jing Qin, Min Zhu

Research Collection School Of Economics

The method of generalized estimating equations (GEE) is a popular tool for analysing longitudinal (panel) data. Often, the covariates collected are time-dependent in nature, for example, age, relapse status, monthly income. When using GEE to analyse longitudinal data with time-dependent covariates, crucial assumptions about the covariates are necessary for valid inferences to be drawn. When those assumptions do not hold or cannot be verified, Pepe and Anderson (1994, Communications in Statistics, Simulations and Computation 23, 939–951) advocated using an independence working correlation assumption in the GEE model as a robust approach. However, using GEE with the independence correlation assumption may …

College of Nursing Faculty Research and Publications

Chronic prenatal stress contributes to poor birth outcomes for women and infants. Importantly, poor birth outcomes are most common among minority and low income women. To investigate underlying mechanisms, we tested the hypothesis that chronic stress related to minority or low income status is associated with glucocorticoid resistance as indicated by disruption in the cytokine-glucocorticoid feedback circuit. Home visits were conducted during which 3rd trimester pregnant women completed stress and depression surveys and provided blood for pro- and anti-inflammatory cytokines. Saliva was collected 5 times the preceding day for diurnal cortisol levels. For statistical analyses, women were grouped 3 ways, …

Enterococci are among the leading pathogens isolated in hospital-acquired infections. Current antimicrobial options for vancomycin-resistant enterococci (VRE) are limited. Prior data suggests that daptomycin > 6mg/kg/day may be used to treat enterococcal infections. We retrospectively evaluated the effectiveness and safety of high-dose daptomycin (HD-daptomycin) therapy (> 6 mg/kg) in a multicenter cohort of adult patients with enterococcal infections to describe the characteristics and outcomes. Two-hundred and forty-five patients were evaluated. Enterococcus faecium was identified in 175 (71%), followed by 49 (20%) Enterococcus faecalis and 21 (9%) Enterococcus spp., overall 204 (83%) were VRE. Enterococcal infections included bacteremia (173, 71%), intra-abdominal (35, …

Stakeholder Perceptions Of Socioenvironmental Impacts From Unconventional Natural Gas Development And Hydraulic Fracturing In The Haynesville Shale, Anthony E. Ladd

Journal of Rural Social Sciences

Environmental controversy over unconventional natural gas development utilizing horizontal drilling and hydraulic “fracking” has been on the rise in recent years. While most of the media attention has been focused on the conflicts in states like Pennsylvania, New York, Texas, and Colorado, the discovery of huge natural gas reserves in the Haynesville Shale formation in 2008 set off a drilling rush that has resulted in differential benefits and risks for various residents. Drawing on current research and extensive interview data collected from a relevant cross-section of community stakeholders, this study offers a descriptive and comparative analysis of the types of …

Project Ngage: Network Supported Hiv Care Engagement For Younger Black Men Who Have Sex With Men And Transgender Persons, Dexter R. Voisin

Faculty Scholarship

Background: Young Black men who have sex with men and transgender persons (YBMSMT) aged 13-29 carry the nation's highest burden of new HIV infections. Studies indicate that YBMSMT have poor retention in care, which is associated with reduced medication adherence and increased virologic failure. Objective: Project nGage is a randomized controlled (RCT) trial evaluating the feasibility and preliminary efficacy of a brief, dyadic intervention designed to promote adherence to HIV primary care in safety-net clinics. Network visualization is used to identify and engage a support confidant (SC) from participants' social networks. A social work interventionist then meets with the SC …

The Recruitment Of Female “Mules” By Transnational Criminal Organizations: Securitization Of Drug Trafficking In The Philippines And Beyond, Stéphanie Martel

Social Transformations Journal of the Global South

Southeast Asia has long been vulnerable to drug trafficking. Recently, intensified flows of persons, goods, and capital across borders have rendered it more fragmented and complex. The recruitment of female drug “mules” by transnational criminal organizations is a growing concern for both national and international counter-trafficking authorities in the region. This phenomenon has been the focus of a particular securitization process, emerging primarily in the Philippines but having regional implications, which has supported the implementation of counter-trafficking policy initiatives on both levels of state and region in Southeast Asia.

Identification And Characterization Of An Effective Antimicrobial Peptide Defensin And Its Effects On Transmission Efficiency, Kody Johnson, Dr. David Erickson

Journal of Undergraduate Research

Among many transmissible infectious diseases falls the Bubonic Plague, a disease that is caused by Yersinia pestis, a bacterium. It is still a concern because there have been human cases as recent as last year in our home state of Utah. While health care has advanced significantly since the last large plague epidemic, there are still areas of the world where health care is not as efficient or advanced and it is in these areas that this disease causes the greatest harm.

Telomere Length Dynamics In Human Memory T Cells Specific For Viruses Causing Acute Or Latent Infections, Joel M. O'Bryan, Marcia Woda, Mary Co, Anuja Mathew, Alan L. Rothman

Institute for Immunology and Informatics Faculty Publications

Background:

Declining telomere length (TL) is associated with T cell senescence. While TL in naïve and memory T cells declines with increasing age, there is limited data on TL dynamics in virus-specific memory CD4⁺ T cells in healthy adults. We combined BrdU-labeling of virus-stimulated T cells followed with flow cytometry-fluorescent in situ hybridization for TL determination. We analyzed TL in T cells specific for several virus infections: non-recurring acute (vaccinia virus, VACV), recurring-acute (influenza A virus, IAV), and reactivating viruses (varicella-zoster virus, VZV, and cytomegalovirus, CMV) in 10 healthy subjects. Additionally, five subjects provided multiple blood samples separated by …

Optimization Of Inpatient Hemodialysis Scheduling Considering Efficiency And Treatment Delays To Minimize Length Of Stay, Manuel Tolentino Peña

Theses

Inpatient dialysis units face an uncertain daily demand of hemodialysis procedures for end-stage renal disease (ESRD) patients hospitalized for health conditions that may or may not be directly related to their renal disease. While hospitalized, these patients must receive hemodialysis in addition to any medical services needed for their primary diagnosis. As a result, when demand for inpatient dialysis is high, treatments and procedures required by these inpatients may be delayed increasing their length of stays (LOS). This research presents an optimization approach for daily scheduling of inpatient hemodialysis to maximize the efficiency of the dialysis unit while minimizing delays …

Phosphorylation Of Calcineurin At A Novel Serine-Proline Rich Region Orchestrates Hyphal Growth And Virulence In Aspergillus Fumigatus, Praveen R. Juvvadi, Christopher Gehrke, Jarrod R. Fortwendel, Frédéric Lamoth, Erik J. Soderblom, Erik C. Cook, Michael A. Hast, Yohannes G. Asfaw, M. Arthur Moseley, Trevor P. Creamer, William J. Steinbach

Molecular and Cellular Biochemistry Faculty Publications

The fungus Aspergillus fumigatus is a leading infectious killer in immunocompromised patients. Calcineurin, a calmodulin (CaM)-dependent protein phosphatase comprised of calcineurin A (CnaA) and calcineurin B (CnaB) subunits, localizes at the hyphal tips and septa to direct A. fumigatus invasion and virulence. Here we identified a novel serine-proline rich region (SPRR) located between two conserved CnaA domains, the CnaB-binding helix and the CaM-binding domain, that is evolutionarily conserved and unique to filamentous fungi and also completely absent in human calcineurin. Phosphopeptide enrichment and tandem mass spectrometry revealed the phosphorylation of A. fumigatus CnaA in vivo at four clustered serine residues …
