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.

A Review Of Gut Failure As A Cause And Consequence Of Critical Illness, Danielle E. Soranno, Craig M. Coopersmith, Jessica F. Brinkworth, Faith N. F. Factora, Julia H. Muntean, Monty G. Mythen, Jacob Raphael, Andrew D. Shaw, Vidula Vachharajani, Jeannette S. Messer

Department of Anesthesiology Faculty Papers

In critical illness, all elements of gut function are perturbed. Dysbiosis develops as the gut microbial community loses taxonomic diversity and new virulence factors appear. Intestinal permeability increases, allowing for translocation of bacteria and/or bacterial products. Epithelial function is altered at a cellular level and homeostasis of the epithelial monolayer is compromised by increased intestinal epithelial cell death and decreased proliferation. Gut immunity is impaired with simultaneous activation of maladaptive pro- and anti-inflammatory signals leading to both tissue damage and susceptibility to infections. Additionally, splanchnic vasoconstriction leads to decreased blood flow with local ischemic changes. Together, these interrelated elements of …

Inhibition Of Il-6 Trans-Signaling Promotes Post-Stroke Functional Recovery In A Sex And Dose-Dependent Manner, Cassandra Hall, Dustin T Nguyen, Kate Mendoza, Chunfeng Tan, Anjali Chauhan

Faculty, Staff and Student Publications

Introduction: Elevated circulating IL-6 levels are associated with poorer outcomes after stroke, and increased serum IL-6 levels are linked to a higher risk of stroke. IL-6 binds to soluble IL-6 receptors (sIL-6R) and subsequently to ubiquitously expressed gp130, initiating proinflammatory trans-signaling. This study tested the hypothesis that inhibiting IL-6 trans-signaling by administering soluble (s) gp130 improves long-term functional outcomes in young mice after stroke.

Methods: Recombinant mouse gp130Fc chimera (sgp130) was administered one hour after middle cerebral artery occlusion (MCAO) followed by twice-weekly administration for 2 weeks in mice (8-15 weeks old). Behavioral assessments were done on days 7 and …

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 …

Fungi And Fungi-Like Entities, Claudia Pogoreutz, Miriam Reverter, Nathalia Delgadillo-Ordonez, Anna Roik

School of Biological and Marine Sciences

Coral microbiology research has long focused on the composition and functional roles of prokaryotic organisms, but microeukaryotic communities, including the enigmatic fungi remain a poorly understood “black box” within coral and other holobionts. Here, we summarise what is known and hypothesised about the diversity, functional traits and potential, and chemodiversity of coral- and reef-associated fungi and fungi-like organisms (FLOs). Finally, we briefly outline the challenges associated with the characterization of marine fungi and provide a perspective for future studies to elucidate the biology, chemical ecology, and organismal interactions of marine fungi and FLOs within coral reef holobionts and their potentially …

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 …

Accelerating Earlier Access To Anti-Tnf-Α Agents With Biosimilar Medicines In The Management Of Inflammatory Bowel Disease, Gionata Fiorino, Ashwin Ananthakrishnan, Russell D Cohen, Raymond K Cross, Parakkal Deepak, Francis A Farraye, Jonas Halfvarson, A Hillary Steinhart

2020-Current year OA Pubs

Data indicate that earlier initiation of anti-tumor necrosis factor alpha (anti-TNF-α) biologic medicines may prevent progression to irreversible bowel damage and improve outcomes for patients with inflammatory bowel disease (IBD), particularly Crohn's disease. However, the high cost of such therapies may restrict access and prevent timely treatment of IBD. Biosimilar anti-TNF-α medicines may represent a valuable opportunity for cost savings and optimized patient outcomes by improving access to advanced therapies and allowing earlier anti-TNF-α treatment initiation. Biosimilar anti-TNF-α medicines have been shown to offer consistent therapeutic outcomes to their reference medicines, yet despite entering the IBD treatment armamentarium over 10 …

The Abandoned Shipwreck Act Of 1987 And The Reaction Of State Historic Preservation Offices, Kelly A. Victor, Gary M. Victor

The Geographical Bulletin

The Abandoned Shipwreck Act of 1987 is perhaps the most important piece of recent federal legislation enacted affecting underwater archaeology and the preservation of underwater historic sites. With this short statute, the federal government vested title to virtually all historic shipwrecks in navigable water to the states. 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 …

Thesis/ Dissertation Defenses

In UAE, dromedary camels (Camelus dromedarius) are considered as vital sources of meat and milk, and they also symbolize the cultural heritage of the region. Understanding healthy dromedary camel’s core microbiome and microbiome diversity is essential for their conservation and sustainable management. To explore the fecal microbiome diversity and core fecal microbiome of healthy dromedary camels, in this study, we analyzed 150 fecal samples from camels collected across 10 different farms in the Dubai region. Each farm maintains healthy camels and provides specific diets and water types, with some farms also focusing on camels for racing purposes. In this study, …

Exploration Of Differential Equation Models For Phage-Bacteria Population Dynamics, John Lawrence Palacios, Rebecca A. Segal

Spora: A Journal of Biomathematics

Bacteriophages are viruses that infect and replicate within bacteria. Lytic phages cause the bacterial cell to burst, killing the bacteria. These types of phages can be used to treat patients with antibiotic-resistant bacterial infections. As a step in developing successful treatment protocols, we aim to understand the population dynamics of phages and bacteria using an in vitro model. We model the dynamics using the Campbell model, which consist of a delay differential equation (DDE), as a base model. We extended the model by including the emergence of phage resistance. We then compared the DDE model with a parallel ordinary differential …

Modulating The Aqueous Micellar Reorganization Of Sequence-Defined Ionic Peptoid Block Copolymers By Ionizable Monomer Position And Solution Ph, Bailee N. Barrett, Pedram Azizihariri, Vijay T. John, Donghui Zhang

Faculty Publications

The micellar aggregation of singly charged sequence-defined ionic peptoid block copolymers can be finely tuned by adjusting the position of the ionizable monomer along the chain and varying the solution pH. The pH-induced structural reorganization of these micelles was found to depend on the position of the ionizable monomer along the chain, influencing the balance of the hydrophobic interactions, excluded volume effect, and electrostatic forces (i.e., charge repulsion, solvation of the ionic monomers, counterion association) that govern the micellar structure. As the solution pH increases, positioning the ionizable monomer closer to the junction of the hydrophobic and hydrophilic blocks causes …

Changing Fire Regimes In The Great Basin Usa, Eva K. Strand, Kori Blankenship, Corey Gucker, Mark Brunson, Eugénie Montblanc

Aspen Bibliography

Wildfire is a natural disturbance in landscapes of the Western United States, but the effects and extents of fire are changing. Differences between historical and contemporary fire regimes can help identify reasons for observed changes in landscape composition. People living and working in the Great Basin, USA, are observing altered fire conditions, but spatial information about the degree and direction of change and departure from historical fire regimes is lacking. This study estimates how fire regimes have changed in the major Great Basin vegetation types over the past 60 years with comparisons to historical (pre-1900) fire regimes. We explore potential …

A Geologist, A Photographer And A Theologian Walk Into The Woods: Wonder, Grief And Hope In An Old-Growth Forest In An Age Of Wildfire, Vincent J. Miller, Frederick J. Swanson, David Paul Bayles

Intersections of Science and Faith

In 2007, Catholic theologian Vince Miller had a sabbatical and went to the H.J. Andrews Experimental Forest in Oregon. In the late 1970s and early '80s, this is the place where the fundamental research was done that established old growth as a certain kind of ecological community. This emerged out of the fuel of forestry, which was largely concerned prior to that with harvest schedules and maximum sustainable yield. So, the research they did there, which was profoundly interdisciplinary, engaged the ecosystem across all sorts of disciplines. Out of that interdisciplinary work, it became a place that began to welcome …

Postnatal Progressive Craniosynostosis: An Unusual Case Presentation Leading To Cascade Diagnosis For Multiple Generations, Jessica T. Ogawa, Maura Guyler, Krystal L. Tomei, Howard D. Wang

Faculty Scholarship

NM_000141.5: FGFR2 c.1032G>A is a pathogenic variant that causes Crouzon syndrome through activation of a new donor splice site. This clinical report highlights the intrafamilial variability that can exist with this specific variant. The proband is a 4-year-old boy who initially presented with concern for seizures. Computed tomography and magnetic resonance imaging revealed pancraniosynostosis and Chiari 1 malformation. Papilledema on fundoscopic exam and copper beaten appearance of the skull on imaging both suggested the presence of elevated intracranial pressure. Genetic testing identified c.1032G>A (p.Ala344=) in FGFR2. Familial testing and genetic evaluation confirmed the same pathogenic variant in the …

A Review Of Racial Differences And Disparities In Ecg, Jianwei Zheng, Chizobam Ani, Islam Abudayyeh, Yunfan Zheng, Cyril Rakovski, Ehsan Yaghmaei, Omolola Ogunyemi

Mathematics, Physics, and Computer Science Faculty Articles and Research

The electrocardiogram (ECG) is a widely used, non-invasive tool for diagnosing a range of cardiovascular conditions, including arrhythmia and heart disease-related structural changes. Despite its critical role in clinical care, racial and ethnic differences in ECG readings are often underexplored or inadequately addressed in research. Variations in key ECG parameters, such as PR interval, QRS duration, QT interval, and T-wave morphology, have been noted across different racial groups. However, the limited research in this area has hindered the development of diagnostic criteria that account for these differences, potentially contributing to healthcare disparities, as ECG interpretation algorithms largely developed from major …

Variation In Thermal Tolerance Plasticity And The Costs Of Heat Exposure In The Estuarine Sea Hare, Phyllaplysia Taylori, Richelle L. Tanner, Rauri C. K. Bowie, Cynthia Y. Wang-Claypool, Jonathan H. Stillman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Climate change is increasing average temperatures and the frequency and intensity of thermal extremes in coastal marine environments. Organisms in coastal marine habitats are accustomed to environmental fluctuations and possess physiological plasticity that may be advantageous in response to increased occurrence of extremes. To examine whether such plasticity is locally adapted to environmental conditions, we investigated the relationship between genetic diversity and thermal tolerance plasticity in 11 populations of the direct-developing intertidal sea hare, Phyllaplysia taylori, on the western coast of the United States. Using whole-organism metrics of muscle function and metabolic rate and a ddRADseq genomic approach, we …

School of Medicine Publications

Background: In the study of coronary artery disease, the mechanisms underlying atherosclerosis initiation and progression or regression remain incompletely understood. Our research conceptualized the cardiovascular system as an integrated network of pumps and pipes, advocating for a paradigm shift from static imaging of coronary stenosis to dynamic assessments of coronary flow. Further review of fluid mechanics highlighted the water hammer phenomenon as a compelling analog for processes in coronary arteries. Methods: In this review, the analytical methodology employed a comprehensive, multifaceted approach that incorporated a review of fluid mechanics principles, in vitro acoustic experimentation, frame-by-frame visual angiographic assessments of in …

Metabolism plays a key role in the maintenance of sleep/wake states. Brain lactate fluctuations are a biomarker of sleep/wake transitions, where increased interstitial fluid (ISF) lactate levels are associated with wakefulness and decreased ISF lactate is required for sleep. ATP-sensitive potassium (K_ATP) channels couple glucose-lactate metabolism with excitability. Using mice lacking K_ATP channel activity (e.g., Kir6.2^−/− mice), we explored how changes in glucose utilization affect cortical electroencephalography (EEG) activity and sleep/wake homeostasis. In the brain, Kir6.2^−/− mice shunt glucose toward glycolysis, reducing neurotransmitter biosynthesis and dampening cortical EEG activity. Kir6.2^−/− mice spent more time …

The prognostic impact of measurable residual disease (MRD) in acute myeloid leukemia (AML) is unequivocal; however, the optimal time point for achieving undetectable MRD is unclear. We retrospectively studied patients with newly diagnosed (ND) AML who achieved remission with frontline intensive chemotherapy and had MRD assessed by flow cytometry after induction (time point 1 [TP1]) and after cycles 2 or 3 (TP2). Cases were grouped into MRD negative (Neg)/Neg, positive (Pos)/Neg, or Pos/Pos at TP1 and TP2, respectively. Of 1980 patients with ND AML, 277 met the inclusion criteria and were included in this analysis. The median relapse-free survival (RFS) …

Associations Of Parental Perceived Health With Child Movement Behaviors Within Two-Parent Households, You Fu, Hayley Almes, Nora Constantino, Doria Schmidt, Ryan D. Burns

International Journal of Physical Activity and Health

This study aimed to examine how perceived parental mental and physical health status was associated with child physical activity, screen time, and sleep. Participants were 6- to 17-year-old minors (N = 20,156; 47.9% female) from the 2022 US National Survey of Children’s Health. Dependent variables were children’s physical activity frequency, screen time, and sleep. Independent variables were parents’ physical and mental health status. Using the Actor-Partner Interdependence Model, two adjusted path models were constructed. One for parent mental health associating with parental physical health, another for parent physical health associating with parental mental health–both further associating with child movement behaviors. …
