Waste Streams From Next Generation Molten Salt Reactors: The Challenge Of Creating An Insoluble Ceramic For Chloride Salt Waste, Alevtina A. Maksimova, Jake W. Amoroso, Matthew Page, Gregory Morrison, Hans Conrad Zur Loye

Faculty Publications

Molten salt reactors (MSRs) design development is of interest to many research groups and companies. Waste management for MSRs is one of the most important issues that needs to be resolved due to its impact on environmental safety, primarily via the dissolution of radionuclides in water. Furthermore, the waste treatment strategy will have a significant influence on the operating cost of MSRs, which is why a reliable process for the immobilization, transportation, storage and disposal of MSR waste must be addressed. This work presents a new approach for the immobilization of chloride salts from molten salt reactors in stable oxyhalide …

Individualized Bayesian Inference Identifies Novel Genetic Variants For Parkinson's Disease, Jin Ren, Yasaman J. Soofi, Md Asad Rahman, Qing Lu, Jinling Liu

Engineering Management and Systems Engineering Faculty Research & Creative Works

Parkinson's disease (PD) is a complex neurodegenerative disorder with a significant genetic component. While genome-wide association studies (GWAS) have been instrumental in identifying genetic variants associated with PD, the reliance on large sample sizes and population-level analyses may overlook variants with lower minor allele frequencies or individual-specific relevance. Individualized Bayesian Inference (IBI) offers a promising method to complement GWAS by identifying and prioritizing candidate genetic markers at both the individual and patients-like-me subgroup levels. This study evaluates the application of IBI to PD genetics, using GWAS as a baseline for comparison. We analyzed genetic data from the Fox Insight online …

Children’s Nutrition Research Center Staff Publications

Skin carotenoid score (SCS) as measured using pressure-mediated reflection spectroscopy has been validated among adults with normal and overweight body mass index, with little validation research among adults with obesity. Therefore, the purpose of this exploratory study was to examine the validity of SCS as an approximation of fruit and vegetable intake among adults with obesity. We used samples from adults with obesity from three prior studies: The first study examined the validity of SCS among 213 adults, 34 with obesity; the second, examined sensitivity of SCS to a β-carotene-rich juice intervention among 162 adults, 14 with obesity; the third …

An Observational Study Of The Effect Of Concomitant Levetiracetam On Apixaban Concentrations In A Hospital Cohort, Chazmyn Riley, Kevin Lam, Cristina Micale, Lynda Thomson, Douglas F. Stickle, Walter K. Kraft

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Despite the lack of evidence of a mechanism-based drug interaction, some professional organizations have advised caution coadministering apixaban and levetiracetam. Eligible patients taking apixaban with or without levetiracetam for any indication for at least 72 h were screened from the electronic medical records. Plasma samples from 77 patients were retrieved from salvaged clinical blood collections. Apixaban minimum and maximum concentrations (Cmin and Cmax) were compared using descriptive statistics in R. While the median Cmin and Cmax appear to be marginally elevated, there were no apparent differences relative to apixaban alone. These findings suggest no apparent interaction of levetiracetam and support …

Effect Of Sprayer Type, Nozzle Selection, And Herbicide Properties On Spray Deposition And Weed Control Efficacy, Mary Joy M. Abit, Analiza Henedina M. Ramirez

The Philippine Agricultural Scientist

Sprayer application efficiency is influenced by sprayer performance, nozzle characteristics, and herbicide properties, which collectively affect spray deposition and weed control. This study evaluated the effects of backpack sprayer type and nozzle configuration on spray output, droplet characteristics, spray coverage, and deposition under Philippine field conditions and compared these characteristics with weed control responses to glyphosate and glufosinate in separate field experiments. Battery-operated (BO) and hand-pumped (HP) backpack sprayers equipped with flat fan and hollow cone nozzles were evaluated. The BO sprayer provided more consistent spray output and maintained discharge rates closer to the target application volume than the HP …

Genomic Investigation Of Population Structure In A Secretive, Semi‐Fossorial Snake (Colubridae: Tropidoclonion Lineatum) Across The Great Plains, Taylor Probst, Cameron D. Siler, Drew R. Davis

School of Integrative Biological & Chemical Sciences Faculty Publications

With advances in genomic technologies, it has become increasingly feasible to generate large numbers of loci to address population genetic and phylogeographic questions. Nevertheless, many widespread and relatively abundant species remain unsampled using molecular approaches. The lined snake ( Tropidoclonion lineatum ), a semi‐fossorial snake distributed across the Great Plains, is one such example. Despite the historical recognition of multiple subspecies based on noted variation in morphological characters, no formal molecular investigation of population structure has been conducted to date due to a paucity of vouchered genetic samples. Here, we present the first genomic assessment of range‐wide population structure in …

Analysis of Diterpenoid Alkaloids from American Aconitum Using LC-MS Metabolomic Methods

by

Yi Zhao

Advisor: Edward J. Kennelly

Aconitum plants have been used as a traditional medicine in Asian countries for millennia to treat pain, rheumatism, syncope, fever, and other conditions. These therapeutic effects are mainly due to the bioactive diterpenoid alkaloids accumulated in the roots. Comparing with the large records and studies of Asian Aconitum and their medicinal use and the broad bioactive compounds, American Aconitum has been rarely investigated, not to mention how American Aconitum has been used medicinally. Based on previous phylogenetic and chemotaxonomic studies of Aconitum …

Children with congenital and acquired heart disease frequently require complex and prolonged pharmacotherapy, often involving off-label cardiovascular medications with narrow therapeutic ranges. Consequently, variability in drug response and medication-related adverse events remains a significant clinical challenge in pediatric cardiology. Pharmacogenetics provides a framework to individualize drug selection and dosing by incorporating genetic variability alongside established clinical and developmental factors. This review outlines the current clinical utility and emerging role of pharmacogenetics in pediatric cardiology, emphasizing applications most relevant to day-to-day patient care. Established pharmacogenetic associations with direct implications for pediatric cardiac practice include gene-drug pairs involving tacrolimus (CYP3A5), …

Remote Sensing Integrated Modeling Of Fall Armyworm Parasitoid Interactions In Africa Using Fractional Differential Equations, Marian Adan, Steeven Belvinos Affognon, Henri E.Z. Tonnang, Klaus Greve, Christian Borgemeister, Georg Goergen

All Peer-Reviewed Publications

The invasion of fall armyworm (Spodoptera frugiperda; FAW) into Africa poses a major threat to agricultural systems, particularly maize production, necessitating effective biological control strategies. This study presents an ecological modelling framework that integrates temperature data with fractional differential equations (FDEs) to investigate interactions between FAW and its parasitoid natural enemies. By incorporating temperature-driven effects on life-history traits and ecological memory dynamics, the model captures key features of host–parasitoid interactions under variable environmental conditions. Equilibrium states corresponding to FAW extinction, parasitoid extinction, and coexistence were analytically derived, and sensitivity analysis of the FAW reproduction number highlighted its central role in …

Coming Soon To A Cellar Near You: Novel Range Expansion Of A Short-Bodied Cellar Spider, Physocyclus Enaulus (Araneae: Pholcidae), In A Building In Central Illinois, Usa, Ricky Gieser, Mark Davis

The Great Lakes Entomologist

A reproductive population of Physocyclus enaulus Crosby, 1926 (Pholcidae: Araneae), a short-bodied cellar spider native to the American southwest and Mexico, is documented for the first time in a single building in Illinois, far outside of their known native range. The means of introduction is unknown but is likely influenced by either accidental hitchhiking spiders or a deliberate introduction to control brown recluse populations. Cellar spiders were purchased and released in the same building to predate on brown recluse spiders, but the first P. enaulus individual was found a year prior to the release. These cellar spiders have a wide-ranging …

Seasonal Emergence, Egg Gallery Characteristics, And Natural Enemies Of The Eastern Ash Bark Beetle, Hylesinus Aculeatus (Coleoptera: Curculionidae: Scolytinae), In Michigan, Robert A. Haack

The Great Lakes Entomologist

Hylesinus aculeatus Say (Coleoptera: Curculionidae: Scolytinae) commonly infests the trunks and limbs of recently dead, dying, or cut ash (Fraxinus spp.) trees in eastern North America. In the Great Lakes region, H. aculeatus is univoltine, overwinters as adults, breeds in late spring and early summer, and constructs transverse biramous egg galleries. I sampled trunk and branch sections from three small-diameter white ash (F. americana L.) trees that were cut in April 1986 in Ingham County, Michigan, and then naturally infested by H. aculeatus and associates. Bolts cut from these trees and placed in an outdoor rearing cage in …

The Culver’s root borer moth (Papaipema sciata) (Lepidoptera: Noctuidae) is a rare Noctuid that requires Culver’s root (Veronicastrum virginicum) to complete its lifecycle within remnant native grasslands and open woodlands in the midwest and northeast United States. We report on 26 years of monitoring this species’ colonization of Culver’s root stems at Algonac State Park (ASP) in Michigan, where prairies have been maintained by prescribed fire since 1990. P. sciata is considered fire sensitive because eggs spend the dormant season in the combustible prairie litter and duff near host plants. The objectives were to determine the …

Could The European Thanasimus Formicarius Outcompete The North American Thanasimus Dubius (Coleoptera: Cleridae) If Introduced To North America?, Robert A. Haack, Robert K. Lawrence

The Great Lakes Entomologist

A federal quarantine was enacted in the United States (US) in the fall of 1992 in response to discovery of the Eurasian pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytinae), in July 1992 in Ohio. The quarantine regulated movement of pine products (e.g., Christmas trees, nursery stock, and logs) at the county level from infested to uninfested US states. A classical biological program was considered for T. piniperda starting in 1995, focusing on the Eurasian clerid beetle Thanasimus formicarius (L.), an important predator of T. piniperda. Concerns were raised in 1996 that if T. formicarius were released in the …

Fecundity Of Thanasimus Dubius (Coleoptera: Cleridae) Rebounds After A Period Of Prey Scarcity, Robert A. Haack, Robert K. Lawrence

The Great Lakes Entomologist

We field-collected Thanasimus dubius (Fabricius) (Coleoptera: Cleridae) adults during spring, maintained them separately in the laboratory, and initially gave them four bark beetle adults [Ips grandicollis (Eichhoff) or Tomicus piniperda (L.) (Coleoptera: Curculionidae: Scolytinae)] daily as prey. Using a subset of the female clerids (N = 41), we assigned them to one of four feeding groups that varied in the number of prey provided daily. For the first four weeks of a 12–week study, the four diets were: four prey daily, two prey daily, one prey daily, and one prey every 2 days. After four weeks, all females were …
