Greater Pain Severity Is Associated With Higher Glucocorticoid Levels In Hair Among A Cohort Of People Living With Hiv, Quan Zhang, Xiaoming Li Ph.D., Shan Qiao Ph.D., Shuaifeng Liu, Zhiyong Shen, Yuejiao Zhou

Faculty Publications

Background: Pain is a common occurrence and persistent symptom, which has an adverse impact on individual well-being and quality of life among people living with HIV (PLHIV). Alteration in the activity of the Hypothalamic-Pituitary-Adrenal (HPA) axis resulting in abnormal glucocorticoid levels had been proposed to play important roles in those associations. Purpose: This study aimed to investigate whether pain severity was associated with hair glucocorticoid levels, a novel method of measuring long-term glucocorticoid exposure, among a large cohort of Chinese PLHIV. Methods: A measure of pain severity and hair samples were collected from 431 adults PLHIV in Guangxi, China. Glucocorticoid …

The element silicon (Si) is required for the growth of silicified organisms in marine environments, such as diatoms. These organisms consume vast amounts of Si together with N, P, and C, connecting the biogeochemical cycles of these elements. Thus, understanding the Si cycle in the ocean is critical for understanding wider issues such as carbon sequestration by the ocean's biological pump. In this review, we show that recent advances in process studies indicate that total Si inputs and outputs, to and from the world ocean, are 57 % and 37 % higher, respectively, than previous estimates. We also update the …

Cluster analyses identified three profiles with completely convergent levels of AMC, PMC, and OSP and three profiles with partially convergent levels. Children in the convergent profiles with average to high …

Radiation-Induced Grain Growth Of Nanocrystalline Alxcocrfeni High-Entropy Alloys, Jianren Zhou, Md Imdadul Islam, Shengmin Guo, Yi Zhang, Fengyuan Lu

Faculty Publications

Grain growth of nanocrystalline AlxCoCrFeNi high-entropy alloys with varying Al contents (x = 0, 1, 2) is studied. The alloys are fabricated by high-energy ball milling and subjected to a 1 MeV Kr2+ ion irradiation bombardment at room temperature up to a dose of 5.625 displacements per atom (dpa). X-ray diffraction (XRD) and transmission electron microscopy (TEM) characterizations show that the crystal structure is face-centered cubic (FCC) for CoCrFeNi (Al-0) alloy and BCC + FCC for Al1CoCrFeNi (Al-1) and Al2CoCrFeNi (Al-2) alloys. In situ TEM observations show that the grain size increases with irradiation dose from 13.8 ± 3, 7.4 …

Efforts On Changing Lifestyle Behaviors May Not Be Enough To Improve Health-Related Quality Of Life Among Adolescents: A Cluster-Randomized Controlled Trial, Alexsandra Da Silva Bandeira, Michael Beets Med, Mph, Phd, Pablo Magno Da Silveira, Marcus Vinicius Veber Lopes, Valter Cordeiro Barbosa Filho, Bruno G.G. Da Costa, Kelly Samara Silva

Faculty Publications

Schools have been the main context for physical activity (PA) and sedentary behavior (SB) interventions among adolescents, but there is inconsistent evidence on whether they also improve dimensions of the health−related quality of life (HRQoL). The aim of this study was to evaluate the effects of a school-based active lifestyle intervention on dimensions of HRQoL. A secondary aim was to verify whether sex, age, and HRQoL at baseline were moderators of the intervention effect. A cluster-randomized controlled trial was conducted at three control and three intervention schools in Florianopolis, Brazil. All students from 7th to 9th grade were invited to …

The doubly labeled water (DLW) method measures total energy expenditure (TEE) in free-living subjects. Several equations are used to convert isotopic data into TEE. Using the International Atomic Energy Agency (IAEA) DLW database (5,756 measurements of adults and children), we show considerable variability is introduced by different equations. The estimated rCO2 is sensitive to the dilution space ratio (DSR) of the two isotopes. Based on performance in validation studies, we propose a new equation based on a new estimate of the mean DSR. The DSR is lower at low body masses (<10 >kg). Using data for 1,021 babies and infants, …

Structural Templates For Imaging Eeg Cortical Sources In Infants, Christian O'Reilly, Eric Larson, J. E. Richards, Mayada Elsabbagh

Faculty Publications

Electroencephalographic (EEG) source reconstruction is a powerful approach that allows anatomical localization of electrophysiological brain activity. Algorithms used to estimate cortical sources require an anatomical model of the head and the brain, generally reconstructed using magnetic resonance imaging (MRI). When such scans are unavailable, a population average can be used for adults, but no average surface template is available for cortical source imaging in infants. To address this issue, we introduce a new series of 13 anatomical models for subjects between zero and 24 months of age. These templates are built from MRI averages and boundary element method (BEM) segmentation …

The Influence Of Geographic Variation In Vegetation Characteristics On Habitat Use And Productivity Of An Endangered Warbler, Ashley M. Long, Heather A. Mathewson, Michael L. Morrison

Faculty Publications

Understanding how geographic variation in environmental conditions influences species’ distributions and population dynamics is critical for effective management of at-risk species and can help us anticipate wildlife responses to future change. The Golden-cheeked Warbler (Setophaga chrysoparia; hereafter warbler) is an endangered migratory songbird that nests in oak-juniper woodland in Texas. From 2009 to 2013, we monitored 895 warbler territories at 90 study sites located across the warbler's breeding range to examine how geographic variation in vegetation characteristics influenced aspects of warbler habitat selection and productivity. We found range-wide variation in the tree species composition and vegetation structure of warbler habitat. …

Background

The impact of maternal diet during pregnancy on child neurodevelopment is of public health and clinical relevance. We evaluated the associations of dietary quality based on the Dietary Approaches to Stop Hypertension (DASH) score and dietary inflammatory potential based on the energy-adjusted Dietary Inflammatory Index (E-DII) score during pregnancy with emotional and behavioral symptoms of offspring at 7 to 10 years of age.

Methods

Individual participant data for 11,870 mother–child pairs from four European cohorts participating in the ALPHABET project were analyzed. Maternal antenatal DASH and E-DII scores were generated from self-completed food frequency questionnaires. Symptoms of depression …

Insect Reproductive Behaviors Are Important Mediators Of Carrion Nutrient Release Into Soil, Brooke K. Woelber-Kastner, Serita D. Frey, Daniel R. Howard, Carrie L. Hall

Faculty Publications

Current declines in terrestrial insect biomass and abundance have raised global concern for the fate of insects and the ecosystem services they provide. However, the ecological and economic contributions of many insects have yet to be quantified. Carrion-specializing invertebrates are important mediators of carrion decomposition; however, the role of their reproductive activities in facilitating this nutrient pulse into ecosystems is poorly understood. Here, we investigate whether insects that sequester carrion belowground for reproduction alter soil biotic and abiotic properties in North American temperate forests. We conducted a field experiment that measured soil conditions in control, surface carrion alone, and beetle-utilized …

Annihilation And Control Of Chiral Domain Walls With Magnetic Fields, Sunil K. Karna, Madalynn Marshall, Weiwei Xie, Lisa Debeer-Schmitt, David P. Young, Ilya Vekhter, William A. Shelton, Andras Kovács, Michalis Charilaou, John F. Ditusa

Faculty Publications

The control of domain walls is central to nearly all magnetic technologies, particularly for information storage and spintronics. Creative attempts to increase storage density need to overcome volatility due to thermal fluctuations of nanoscopic domains and heating limitations. Topological defects, such as solitons, skyrmions, and merons, may be much less susceptible to fluctuations, owing to topological constraints, while also being controllable with low current densities. Here, we present the first evidence for soliton/soliton and soliton/antisoliton domain walls in the hexagonal chiral magnet Mn1/3NbS2 that respond asymmetrically to magnetic fields and exhibit pair-annihilation. This is important because it suggests the possibility …

Compoundhetvip: Compound Heterozygous Variant Identification Pipeline, Dustin B. Miller, Stephen R. Picollo

Faculty Publications

Compound Heterozygous ( CH) variant identification requires distinguishing maternally from paternally derived nucleotides, a process that requires numerous computational tools. Using such tools often introduces unforeseen challenges such as installation procedures that are operating-system specific, software dependencies that must be installed, and formatting requirements for input files. To overcome these challenges, we developed Compound Heterozygous Variant Identification Pipeline (CompoundHetVIP), which uses a single Docker image to encapsulate commonly used software tools for file aggregation ( BCFtools or GATK4), VCF liftover ( Picard Tools), joint-genotyping ( GATK4), file conversion ( Plink2), phasing ( SHAPEIT2, Beagle …

The Worst Is Behind Us: News Media Choice And False Optimism In The Summer Of 2020, Lawrence C. Hamilton, Thomas G. Safford

Faculty Publications

In the summer of 2020, mitigation efforts slowed the first US wave of the COVID-19 pandemic. Experts warned, however, that without coordinated, sustained mitigation—such as testing and tracing, limited travel or gatherings, social distancing and mask wearing—the worst could lie ahead. A July survey found majority (59%) agreement with the expert warnings, while a minority (27%) mistakenly thought that the worst was behind us, or that COVID-19 was not a real problem. Among frequent Fox News and conservative talk radio consumers, however, large majorities (67–80%) held such false optimism or denial views, in contrast with small minorities (9–16%) among public …

Religiousness And Levels Of Hazardous Alcohol Use: A Latent Profile Analysis, Peter J. Jankowski, Sam A. Hardy, Byron L. Zamboanga, Lindsay S. Ham, Seth J. Schwartz, Su Yeong Kim, Larry F. Forthun, Melina M. Bersamin, Roxanne A. Donovan, Susan Krauss Whitbourne, Erica A. Hurley, Miguel Ángel Cano

Faculty Publications

Prior person-centered research has consistently identified a subgroup of highly religious participants that uses significantly less alcohol when compared to the other subgroups. The construct of religious motivation is absent from existing examinations of the nuanced combinations of religiousness dimensions within persons, and alcohol expectancy valuations have yet to be included as outcome variables. Variable-centered approaches have found religious motivation and alcohol expectancy valuations to play a protective role against individuals’ hazardous alcohol use. The current study examined latent religiousness profiles and hazardous alcohol use in a large, multisite sample of ethnically diverse college students. The sample consisted of 7412 …

Declining Bacteria, Lead, And Sulphate, And Rising Ph And Oxygen In The Lower Mississippi River, R. Eugene Turner

Faculty Publications

Various air and water pollution issues in the US were confronted in the last 60 years using national policy legislation, notably the Clean Water Act and the Clean Air Act. I examine changes in the concentrations of bacteria, oxygen, lead, and sulphate at the terminus of the Mississippi River before and after these pollution abatement efforts. Microbial concentrations increased or were stable from 1909 to 1980 but decreased about 3 orders of magnitude after the 1970s, while the average oxygen content increased. A large decline in lead concentration occurred after the 1960s, along with a less dramatic decline in sulphate …

Faculty Publications

Interest has been growing in regard to increasing the public health workforce and standardizing training to ensure there are competent professionals to support rebuilding and reinforcing the public health infrastructure of the United States. The need for public health leaders was recognized as early as the hookworm control campaign during 1909–1914 when it became apparent that prevention of disease should be distinct from clinical medicine and should be conducted by professionally trained, dedicated full-time public health practitioners. In recent years, research on the public health workforce and on standardizing health workforce education has significantly expanded. A key element of such …

Taking Advantage Of Institutional Weakness? Political Stability And Foreign Subsidiary Survival In Primary Industries, Nathaniel C. Lupton, Donya Behnam, Alfredo Jiménez

Faculty Publications

Purpose

This paper aims to investigate the extent to which locating primary industry subsidiaries in politically unstable countries impacts their survival. The authors argue that foreign multinational enterprises in less stable political environments can shape policies that are impactful on the costs of operating in primary industries and avoid compliance with more stringent policies at home.

Design/methodology/approach

Using a sample of 753 primary sector investments of Japanese multinational enterprises during the period 1986 to 2013, the authors conduct a parametric survival analysis of the relationship between political stability and subsidiary survival.

Findings

Political instability has a slight, curvilinear relationship with …

State Consistence Of Data-Driven Reduced Order Models For Parametric Aeroelastic Analysis, William C. Krolick, Jung I. Shu, Yi Wang, Kapil Pant

Faculty Publications

This paper investigates the state consistence of parametric data-driven reduced order models (ROMs) in a state-space form obtained by various system identification methods, including autoregressive exogenous (ARX) and subspace identification (N4SID), for aeroelastic analysis in varying flight conditions. The target flight envelop is first partitioned into discrete grid points, on each of which an aerodynamic ROM is constructed using system identification to capture the dependence of the generalized aerodynamic force on the generalized displacement of structural modes. High-fidelity aeroelastic modal perturbation simulations are used to generate the ROM training and verification data. Aerodynamic ROMs not on the grid point are …
