Plant and Soil Sciences Faculty Publications

Licochalcone A (LCA) is a characteristic compound in licorice Glycyrrhiza inflata and is widely utilized in pharmaceutical and cosmetic industries. However, the biosynthetic pathway and regulatory mechanisms of LCA remain poorly understood. In this study, we first found the accumulation of LCA is induced by methyl jasmonate (MeJA). Given that MYB transcriptional factors are well-documented as key regulators of flavonoid biosynthesis, we identified a total of 147 GiR2R3-MYB genes in G. inflata, which were classified into 28 subgroups. The chromosome distributions, sequence characteristics, gene structures, duplication events and cis-acting elements were also investigated. Through integrated analysis of GiR2R3-MYBs expression patterns …

Post-Translational Control Of Biotic Stress-Related Nicotine Biosynthesis By A Map Kinase Signaling Cascade, Yan Zhou, Yongliang Liu, Ruiqing Lyu, Sanjay Kumar Singh, Xueyi Sui, Xin Hou, Sitakanta Pattanaik, Ling Yuan

Plant and Soil Sciences Faculty Publications

The evolutionarily conserved mitogen-activated protein kinase (MAPK) cascades relay extracellular signals into cells, triggering a variety of cellular responses. We previously revealed NtMPK4 as a positive regulator of nicotine biosynthesis; however, its upstream regulation remains unclear. Here, we characterized a MAPK cascade, comprising NtMEKK1b, NtMPKK2a, and NtMPK4, that promotes nicotine biosynthesis. This signaling module transduces external cues, including jasmonate and pathogen elicitors such as flg22, into post-translational modifications that enhance transcriptional activity and pathway gene expression. NtMPKK2a physically interacts with and phosphorylates NtMPK4 in vivo, confirming its role as an upstream kinase. RNAi-mediated silencing of NtMPKK2a significantly reduced the expression …

Low Temperature Green Synthesis Of Red Emitting Pb-Free Csmnbr3Perovskite Films, Saurabh Singh, Xiyu Wen, Fuqian Yang

Chemical and Materials Engineering Faculty Publications

Lead halide perovskites (APbX₃) have demonstrated exceptional opto-electronic properties, but their inherent toxicity and environmental hazards hindered their practical deployment in display technologies such as liquid crystal display (LCD) backlights. Herein, we report for the first time a facile, water-mediated synthesis of red-emitting CsMnBr₃ thin films from an aqueous solution of CsBr and MnBr₂ precursors at a low temperature of ∼50 °C. Unlike traditional synthesis routes reported for synthesis of CsMnBr₃ powders or nanocrystals, relying heavily on toxic solvents, high temperatures, or inert atmospheres, the green approach utilizes water as a benign medium to facilitate …

Sustained Increase In Extracellular Atp In The Lung Induced By Chronic Inhalation Exposure To Nitrogen Dioxide, Nai Ju Chan, Yueh Yin Chen, Chun Chun Hsu, You Shuei Lin, Maxwell Zakeri, Mehdi Khosravi, Lu Yuan Lee

Physiology Faculty Publications

Nitrogen dioxide (NO₂) is an environmental air pollutant and a potent oxidant. Epidemiological studies have revealed a close association between chronic cough and long-term inhalation exposure to NO₂. ATP can be released from airway/lung epithelial cells upon inhalation exposure to oxidants, and convincing evidence established in recent clinical studies indicated that extracellular ATP in the respiratory tract plays an important role in the pathogenesis of refractory chronic cough. However, whether inhalation exposure to NO₂ elevates the ATP release in the lung is not yet known. Results of this study showed: 1) in awake rats, acute …

Physics and Astronomy Faculty Publications

The AGN Space Telescope and Optical Reverberation Mapping (STORM) 2 campaign targeted Mrk 817 with intensive multiwavelength monitoring and found its soft X-ray emission to be strongly absorbed. We present results from 157 near-IR spectra with an average cadence of a few days. Whereas the hot dust reverberation signal as tracked by the continuum flux does not have a clear response, we recover a dust reverberation radius of ∼90 lt-days from the blackbody dust temperature light curve. This radius is consistent with previous photometric reverberation mapping results when Mrk 817 was in an unobscured state. The heating/cooling process we observe …

A Comparison Of Time-Dependent Cloudy Astrophysical Code Simulations With Experimental X-Ray Spectra From Kev Laser-Generated Argon Plasmas, N. Rathee, F. P. Keenan, R. J. R. Williams, Gary Ferland, S. J. Rose, S. White, D. Riley

Physics and Astronomy Faculty Publications

We have generated strongly photoionized Ar plasmas in experiments designed to use primarily X-ray l-shell line emission generated from Ag foils irradiated by the VULCAN high-power laser at the UK Central Laser Facility. The principle of the experiment is that use of line emission rather than the usual sub-keV quasi-blackbody source allows keV radiation to play a more dominant role compared to softer X-rays and thus mimic the effect of a blackbody with a higher effective spectral temperature. Our aim is to reproduce in the laboratory the extreme photoionization conditions found in accretion-powered astrophysical sources. In this paper, we compare …

Deep Learning-Based Quantification Of Tall Fescue Abundance In Pastures, Rose E. Binkley, Samuel R. Revolinski, Echo Elizabeth Gotsick, Ray Smith, Zeya Wang, Katsutoshi Mizuta

Plant and Soil Sciences Faculty Publications

Accurate and rapid measurement of tall fescue abundance is essential for efficient forage management and mitigating livestock exposure to potential endophyte-related toxicity. Traditional visual estimation methods are labor-intensive and are subject to change depending on the observer doing the calculations, which limits their scalability and consistency. This study explores the application of deep learning techniques to automate and improve the classification of tall fescue abundance across pasture systems in Kentucky. Ground-truth abundance classes were evaluated using one of the traditional methods with occupancy grid and compared against estimates derived from red-green-blue images. Two convolutional neural network architectures, YouOnlyLookOnce (YOLO) and …

Driving Employee Engagement Across Sectors: Current Evidence And An Agenda For Future Research, Taha Hameduddin, Kerstin Alfes, Adrian Ritz

Public Policy and Administration Faculty Publications

Employee engagement has emerged as a critical employee attitude linked to employee motivation and organisational performance and has successfully embedded itself in governments around the world. Apart from a few exceptions, however, much of what we know about engagement does not attend to the institutional context of public institutions and whether private-sector theories and approaches to driving employee engagement work well in public sector organisations. To address this gap, we systematically review the evidence on antecedents of employee engagement, and determine whether and how sectoral differences may matter. We then discuss the findings and contextualise the debate surrounding the employee …

Agricultural Economics Faculty Publications

The USDA Agricultural Marketing Service has invested in direct-to-consumer initiatives to expand local food consumption and enhance farmers market opportunities. To evaluate the effectiveness of these efforts, this study employs a sample-selected ordered probit model to analyze consumer perceptions of farmers market performance across four states in the Southeast United States. Specifically, we examine differences in awareness and performance of product quality, diversity, and market infrastructure. Awareness and perceptions vary significantly by age, other demographics, and state. These insights provide market organizers and policymakers with data-driven strategies to tailor marketing efforts and improve engagement across diverse consumer segments.

The Association Between Personal Particulate Matter Exposures And Cognitive Function Among Stroke Patients, Kentucky, Usa, Nana Afua Ankomah Dei

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Stroke, a major cause of long-term disability and cognitive problems in the U.S., significantly affects people’s quality of life. Exposure to particulate matter (PM_2.5) may result in systemic inflammation and oxidative stress, which can worsen the cognitive function of post-thrombectomy stroke patients. This project thus assessed the relationship between PM_2.5 exposure and its effect on the cognitive function of post-thrombectomy stroke patients. Fifteen stroke patients (9 non-Appalachian and 6 Appalachian) undergone thrombectomy were recruited. Personal PM_2.5 exposure was measured using wearable sensors for a week during the study period. Montreal Cognitive Assessment (MoCA) scores and covariates …

Gill Heart & Vascular Institute Faculty Publications

Background: Dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) remains a cornerstone for preventing ischemic events; however, the optimal long-term single antiplatelet therapy after completion of DAPT remains unclear. We aimed to compare clopidogrel and aspirin monotherapy after completion of the standard duration of DAPT.

Methods: A systematic search was conducted on PubMed, Scopus, Cochrane Library, and Web of Science from inception to April 2025. We included randomized clinical trials and observational studies that compared aspirin versus clopidogrel monotherapy after completion of standard-duration DAPT. The primary and co-primary outcomes were major adverse cardiovascular events (MACE) and major bleeding, respectively. …

Cross-Linking Peg Microgels With Mesoporous Organosilica Nanoparticles To Engineer Microporous Annealed Particle Scaffold Properties, Jonathan M. Zuidema, Alessandro Ajo, Marco Carofiglio, Luisa De Cola

Mechanical Engineering Faculty Publications

Microporous annealed particle (MAP) scaffolds composed of cross-linked microgels are emerging as important biomaterials due to their modular design, high porosity, and large surface area, which allow for highly tailored properties, cellular infiltration, nutrient and waste exchange, and improved drug release characteristics. To further expand on these technologies and enhance their modular design, thiolated mesoporous organosilica nanoparticles (ssMSN-SH), which degrade in response to glutathione, were first cross-linked inside of 4-arm poly(ethylene glycol) maleimide microgels. The microgel size, rheological properties, and payload release characteristics were determined. Hierarchical MAP scaffolds were then created by cross-linking 4-arm poly(ethylene glycol) maleimide microgels with ssMSN-SH. …

Cross-Neutralization And Antigenic Characterization Of Simian And Equine Group A Rotaviruses, Shalini Soni, Lianne G. Eertink, Ni Shuisong, Alan T. Loynachan, Samantha M. Barnum, Emma Adam, Michael A. Kennedy, Dan Wang, Feng Li

Veterinary Science Faculty Publications

Rotaviral diarrhea in foals is caused by two dominant G3P[12] and G14P[12] genotypes of equine rotavirus A (ERVA). Protection of foals against ERVA infection and disease is achievable by passive antibody transfer through colostrum from mares receiving inactivated monovalent G3P[12] vaccine. Simian rotavirus SA11 G3P[2] is also included in ERVA vaccines to protect foals. Here, we characterized cross-neutralization and protection among three distinctive rotaviruses carrying the same or different G (defined by VP7) or P (defined by VP4) genotype by using a rabbit and equine monospecific antisera panel coupled with structural and computational analyses of viral epitopes. Data from these …

Data-Driven Thresholds For Standardized Classification Of Severe Alzheimer’S Disease Neuropathology Using Digital Neuropathology, Ryan K. Shahidehpour, Allison M. Neltner, Mitchell A. Klusty, Cole Corbett, Angelique D. Gonzalez, David A. Gutman, David W. Fardo, Adam D. Bachstetter, Cody Bumgardner, Margaret E. Flanagan, Peter T. Nelson

Sanders-Brown Center on Aging Faculty Publications

Alzheimer's disease neuropathological changes (ADNC)—operationalized with semi-quantitative parameters—represent the consensus-based gold standard for diagnostic evaluation of disease severity. Although useful, ADNC diagnostic frameworks have limitations, particularly in advanced disease stages where pathological severity varies widely within a given diagnostic category. Further, some individuals lacking cognitive impairment are inappropriately categorized as having severe ADNC. In this study, quantitative pathology metrics and alternative tissue sampling schemes were integrated with data about premortem cognitive status, in order to derive clinically informed neuropathologic diagnostic thresholds. Specific goals of the current study were to generate data-driven, standardized diagnostic cut-points, with the most severe stages of …

Knowledge Based Automated Planning For Non-Coplanar Vmat Stereotactic Radiosurgery In Ocular Malignancies, Chase Cochran, Shane Mccarthy, William St. Clair, Damodar Pokhrel

Radiation Medicine Faculty Publications

Background and Purpose: Stereotactic radiosurgery/radiotherapy (SRS/SRT) has emerged as a less invasive alternative to enucleation in the management of ocular malignancies. SRS/SRT planning is time-consuming, complex, and the plan quality depends on the experience of the treatment planner. We demonstrate the use of RapidPlan modeling in conjunction with HyperArc for the treatment of ocular diseases to improve planning efficiency, consistency, and quality.

Materials and Methods: A HyperArc-based RapidPlan (HARP) model was iteratively trained on 80 patient datasets that simulated ocular malignancies. Twenty additional patient datasets were reserved for model testing and comparison with manual plans. Each testing dataset was both …

Radiation Medicine Faculty Publications

Designing and interpreting early phase trials of theranostic radiopharmaceuticals remains challenging because it is difficult to isolate effective levels of activity in enriched patient populations that would be worth following up in later-phase development. This study explores the known challenges and emerging opportunities for clinical research on patients with uterine cervical cancer. We identified eight randomized combination trials for advanced-stage uterine cervix cancer that were activated between 2011 and 2022 and tabulated their results to determine whether combinations were better than individual constituents and which suitable study population is best situated for the study of a new theranostic agent. In …

From Anxiety To Stewardship: An Autoethnographic Study Of Therapist Development, Christie Ellis

This autoethnographic study investigated the role of ROM in shaping therapist identity development within a university-based marriage and family therapy training clinic. Qualitative data included 34 reflective journal entries analyzed using reflexive thematic analysis, and quantitative data included multiple client outcome trajectories across several clinical measures compared descriptively with prototypical change trajectories derived from MFT-PRN datasets. Qualitative findings reflected a developmental progression from initial anxiety and performance concerns toward increased confidence, attunement, …

Localized Periodontitis In Young Individuals: Aggregatibacter Jp2 Clone, Immunological Dysfunctions And Other Stories, Luigi Nibali, Meaad M. Alamri, Manuela Maria Viana Miguel, Luciana M. Shaddox

Oral Health Science Faculty Publications

Grade C molar-incisor pattern periodontitis (C-MIP) is the latest in a series of names given to a unique phenotype, characterized by an aggressive and rapid loss of tooth-supporting structures, starting early in life and usually affecting first molars and incisors. Although much less prevalent than the more generalized “chronic” forms of this disease in adults, it affects mostly young individuals of lower socioeconomic status and African descent, or from mixed-race populations, and shows a strong familial aggregation, pointing to a possible genetic contribution, yet not fully elucidated. Even though most of the studies report this disease in adolescents/young adults, it …

Neuroscience Faculty Publications

Introduction: Sleep and circadian disturbances are early Alzheimer's disease (AD) features, yet mechanisms linking amyloid pathology, neuroinflammation, and sex differences remain unclear.

Methods: We longitudinally assessed sleep, circadian rhythms, and cognition in female and male hAPP^SAA knock-in and control mice from 2 to 19 months using piezoelectric monitoring. Aged mice (15 months) received MW151, a glial cytokine inhibitor (2.5 mg/kg, every other day, 6 weeks).

Results: Only females exhibited midlife reductions in light-phase sleep, increased rhythm fragmentation, and reduced rhythm stability, coinciding with selective reversal learning deficits, effects independent of amyloid or cytokine burden. MW151 increased light-phase sleep and …

Accelerator Based Fusion Reactor With Magnetic Mirror, Keh-Fei Liu

Physics and Astronomy Faculty Publications

We consider an implementation of the novel accelerator-based fusion reactor scheme using a setup in which ion and electron beams are injected into the end openings of an axisymmetric magnetic mirror. While the magnetic mirror ensures transverse confinement of the plasma, the injected beams contribute to axial confinement, thereby extending the overall plasma lifetime. The ion beam energy is initially set above the resonance region of the fusion reactions, allowing fusion to occur both via resonance and thermal mechanisms as the beam slows down to the plasma temperature. Beam energy loss (stopping power) contributes to plasma heating, offsetting radiative losses …

Physics and Astronomy Faculty Publications

We analyze several key rest-optical emission-line ratios in a sample of 828 galaxies as well as composite spectra from JADES DR3 in the range 1.4 <  z <  7. These emission-line ratios include: [O iii]λ5008/Hβ, [N ii]λ6585/Hα, [S ii]λλ6718, 6733/Hα, [O i]λ6302/Hα, O32, R23, Ne3O2, and RO2Ne3. We find evidence for a harder ionizing spectrum at z ∼ 3.5 compared to z ∼ 2 at fixed gas-phase metallicity, resulting in a pronounced shift in the star-forming galaxy locus on the [N ii]/Hα Baldwin-Phillips-Terlevich (BPT) diagram and the O32 versus R23 diagram. At …
