Jc Polyomavirus Pooled Seropositivity Prevalence In Healthy Subjects, Lenka J. Kimla Feb 2025

Jc Polyomavirus Pooled Seropositivity Prevalence In Healthy Subjects, Lenka J. Kimla

Walden Dissertations and Doctoral Studies

JC polyomavirus (JCV) causes progressive multifocal leukoencephalopathy in immunocompromised individuals and has been linked to cancer development. To-date, no information is available about the JCV seroprevalence in the healthy (nondiseased) population or whether this virus is ecologically connected to humans. The aim of this systematic literature review and meta-analysis was to the estimate the overall seroprevalence of JCV in the healthy human population by age, region, and testing method. A meta-analysis conducted on 24 studies revealed a pooled JCV seroprevalence of 60% (95% CI, 55% - 65%) with statistically significant effect size (z = 32.93, p < 0.001). Meta-regression and subgroup analyses with STATA18 showed that age and region had a strong positive predictive value on prevalence (R = .578, R2 = 0.334, F(2,52) = 12.543, p < 0.001) whereas the testing method had no significant effect on prevalence. The theories that grounded this study were the ecological model and the systems theory, which support the study result that JCV appears to be ubiquitous in the human population with JCV being acquired very early in life. The results of the systematic literature review indicated that JCV is transmitted via fecal-oral and respiratory routes within and outside of families. Most infants are infected with JCV by the age of 6 months and JCV seronegativity may not be indicative of a lack of an underlying JCV infection. JCV seropositivity increases with age, which is most probably by viral reactivation due to immune senescence. These findings have positive social change implications with JCV treatment, screening, and vaccine development.


Leveraging Arginine Catabolism To Treat Metabolic Complications, Yiming Zhang Feb 2025

Leveraging Arginine Catabolism To Treat Metabolic Complications, Yiming Zhang

Arts & Sciences Graduate Student Theses and Dissertations

Fasting and caloric restriction are effective to treat patients with pre-diabetes or metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), but intensive lifestyle changes are difficult for many to implement and sustain. Therefore, by identifying and studying fasting-mediated signals, we hope to elicit and convey the therapeutic effects of fasting against MASLD without actual physiological fasting. We discovered a key pathway in the liver through unbiased transcriptomic screening in fasted mice, a novel glucose fasting-activated effector: the amino acid hydrolase, arginase 2 (ARG2). Our previously published data demonstrates that forced hepatocyte-specific Arg2 overexpression is …


Tau Oligomers Resist Phase Separation, Lathan Lucas, Phoebe S Tsoi, Josephine C Ferreon, Allan Chris M Ferreon Feb 2025

Tau Oligomers Resist Phase Separation, Lathan Lucas, Phoebe S Tsoi, Josephine C Ferreon, Allan Chris M Ferreon

Faculty, Staff and Students Publications

Tau is a microtubule-associated protein that undergoes liquid-liquid phase separation (LLPS) to form condensates under physiological conditions, facilitating microtubule stabilization and intracellular transport. LLPS has also been implicated in pathological Tau aggregation, which contributes to tauopathies such as Alzheimer's disease. While LLPS is known to promote Tau aggregation, the relationship between Tau's structural states and its phase separation behavior remains poorly defined. Here, we examine how oligomerization modulates Tau LLPS and uncover key distinctions between monomeric, oligomeric, and amyloidogenic Tau species. Using dynamic light scattering and fluorescence microscopy, we monitored oligomer formation over time and assessed oligomeric Tau's ability to …

Support For The United States In The United Nations On Cold War Issues And The Distribution Of Foreign Aid To Central American And Caribbean Countries, Gerald R. Webster Feb 2025

Support For The United States In The United Nations On Cold War Issues And The Distribution Of Foreign Aid To Central American And Caribbean Countries, Gerald R. Webster

The Geographical Bulletin

The agenda of the General Assembly of the United Nations has been dominated by Cold War battles between the United States and the Soviet Union during much of the organization's 45-year history. Do countries who support the United States on votes associated with the Cold War receive larger quantities of U.S. foreign assistance? This paper examines two hypotheses pertaining to this question with regard to the voting behavior of 12 Central American and Caribbean countries between 1970 and 1987. The cross-sectional analysis finds significant evidence for a link between U.N. voting behavior and the quantities of per capita U.S. foreign …

The act also changed existing legal principles in order to allow the states to enact their own laws to protect and preserve underwater historic resources. This article begins with a discussion of the Abandoned Shipreck Act of 1987- what it is, what it does and how it has changed the law related to …


Review Of Building Representative Community Archives: Inclusive Strategies In Practice, Shir Bach Feb 2025

Review Of Building Representative Community Archives: Inclusive Strategies In Practice, Shir Bach

Journal of Contemporary Archival Studies

In Building Representative Community Archives, editor Hannah Leah Crummé sets out to provide a practical guide to building community archives through ten case studies. The volume covers three types of projects: oral history, collection and curation, and reassessment. With some exceptions, community-created and community-maintained archives are sidelined in this collection. The majority of case studies describe academic special collections units embracing community archival principles and practices to meet their own goals, and some chapters do not meaningfully engage with community archives at all. Though many chapters succeed on their own terms, the misleading framing produces a collection that is …

Disability Measures Used In U.S. Federal Surveys Significantly Underreport Disability Status, Nastassia Vaitsiakhovich, Scott D. Landes, Jean P. Hall, Bonnielin K. Swenor Feb 2025

Disability Measures Used In U.S. Federal Surveys Significantly Underreport Disability Status, Nastassia Vaitsiakhovich, Scott D. Landes, Jean P. Hall, Bonnielin K. Swenor

Population Health Research Brief Series

U.S. federal surveys commonly use two question sets to measure disability: the American Community Survey (ACS-6) and the Washington Group Short Set (WG-SS). This data slice uses data from the 2011-2012 National Health Interview Survey to examine the percentage of disabled people captured by these two different survey sets. The authors find that both sets of questions significantly underreport disability statuses that are not directly addressed in their question prompts, including intellectual disability, developmental disability, birth defects, mental health disability, diabetes, and cancer.

Monitoring And Modeling Legacy Tree Response To Restoration Treatments In The Klamath Mountains, Oregon, Usa, Isaac Joseph Ball

Dissertations and Theses

Climate change and its disruption of historical drought and wildfire patterns pose a substantial threat to forest health in the western United States. This threat is compounded by past management practices like fire suppression. The largest, oldest, and most ecologically valuable trees are particularly vulnerable, making their conservation a key objective of climate-adaptive forest management. Restoration treatments such as mechanical thinning have been shown to enhance tree growth and drought resilience in dry conifer forests, but long-term monitoring is necessary to understand their sustained effects. This study used dendroecological tree-ring analysis to investigate the effects of thinning on the growth, …

Potential Of Individual Upper-Limb Muscles To Contribute To Postural Tremor: Simulations From Neural Drive To Joint Rotation, Spencer A. Baker, Landon J. Beutler, Daniel B. Free, Dario Farina, Steven Knight Charles

Faculty Publications

Background: It is unclear which muscles contribute most to tremor and should therefore be targeted by tremor suppression methods. Previous studies used mathematical models to investigate how upper-limb biomechanics affect muscles’ potential to generate tremor. These investigations yielded principles, but the models included at most only 15 muscles. Here we expand previous models to include 50 upper-limb muscles, simulate tremor propagation, and test the validity of the previously postulated principles. Methods: Tremor propagation was characterized using the gains between tremorogenic neural drive to the 50 muscles (inputs) and tremulous joint rotations in the 7 joint degreesof- freedom (DOF) from shoulder …

Treatment with antibiotics is a major risk factor for Clostridioides difficile infection, likely due to depletion of the gastrointestinal microbiota. Two microbiota-mediated mechanisms thought to limit C. difficile colonization include the conversion of conjugated primary bile salts into secondary bile salts toxic to C. difficile growth and competition between the microbiota and C. difficile for limiting nutrients. Using a continuous flow model that simulates the nutrient conditions of the distal colon, we investigated how treatment with 6 clinically used antibiotics influenced susceptibility to C. difficile infection in 12 different microbial communities cultivated from healthy individuals. Antibiotic treatment reduced microbial richness; …
