Precision Approaches Improve Community Health, Roger A. Rennekamp, David Buys Sep 2026

Precision Approaches Improve Community Health, Roger A. Rennekamp, David Buys

Journal of Extension

Recent advances in data science provide Extension practitioners with access to data sorted by zip code, census tract, or neighborhood. Such hyper-local data now allows Extension personnel to assess community needs and assets at a more granular level and focus their work on the people and communities of greatest need. In this article, we introduce an approach we refer to as precision public health. Using such a precision approach to community assessment and, ultimately, programming can save money, increase the likelihood of producing measurable results, and create more manageable workloads for county-based Extension personnel.

Individualized Bayesian Inference Identifies Novel Genetic Variants For Parkinson's Disease, Jin Ren, Yasaman J. Soofi, Md Asad Rahman, Qing Lu, Jinling Liu Sep 2026

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 …

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 …

The Plastic Footprint Of Sugar: Microplastic Contamination In Bangladesh’S Commercial Sugar, Sadia Afrin, Nayon Hossain, Mostafizur Rahman

Research outputs 2022 to 2026

The presence of microplastics (MPs) in food has emerged as an environmental and public health concern, yet evidence regarding their occurrence in refined dietary commodities remains limited. This study assesses microplastic contamination in commercially available sugar and estimates the daily intake of MPs. Seven branded and non-branded sugar products were analysed using stereomicroscopy for particle characterization and FTIR spectroscopy for polymer identification. Microplastics were detected in 95% of samples, with concentrations ranging from 210 to 508 particles/kg. Branded sugar contained 322 ± 109.53 particles/kg, while non-branded sugar exhibited 403 ± 148.5 particles/kg, indicating comparatively higher contamination in freely available market …

Meikle, Kevin Huynh, Changyu Yi, Habtamu B. Beyene, Agus Salim, Michelle Cinel, Nat Mellett, John Blangero Sep 2026

Integration Of Lipidomic And Polygenic Risk Scores Within Contemporary Clinical Cardiovascular Risk Assessment Pathways: A Multi-Cohort Development And Validation Study, Aleksandar Dakic, Jingqin Wu, Tingting Wang, Thomas G. Meikle, Kevin Huynh, Changyu Yi, Habtamu B. Beyene, Agus Salim, Michelle Cinel, Nat Mellett, John Blangero

Human Genetics Publications

Background: Guideline-recommended clinical risk scores such as AusCVDRisk underestimate cardiovascular disease (CVD) risk in a substantial proportion of individuals who later experience events, with up to 65% initially classified as low or intermediate risk. This limitation is most consequential in the intermediate-risk group, where treatment decisions are uncertain and additional risk refinement could alter management. Circulating lipid species and inherited genetic variation capture complementary molecular aspects of atherosclerotic risk that are not fully reflected by conventional clinical variables, but are not routinely incorporated into primary-care risk assessment. We investigated whether selective integration of lipidomic and genomic risk signals into AusCVDRisk …

Sec-Saxs And Sans Analyses Of The Talin•Vinculin Complex, Gilbert Reyes Sep 2026

Sec-Saxs And Sans Analyses Of The Talin•Vinculin Complex, Gilbert Reyes

Dissertations, Theses, and Capstone Projects

Focal adhesions (FA) are integrin-based cell-matrix adhesion sites composed of adaptor proteins that facilitate the generation of traction forces important for biological functions such as cell migration, embryo development, wound healing, tissue organization and stability, and immune responses. Mature FA are observed when both autoinhibited multi-domain scaffolding protein talin and membrane-cytoskeletal protein vinculin are activated and interact thus promoting the assembly and function of FA. While research has resolved truncated sections of autoinhibited talin and recruitment of vinculin due to mechanotransduction that exposes cryptic vinculin binding sites (VBS), little is known about the global modifications of full length talin in …

The Cranial Nerves And Electrical Stimulation, Devin K. P. Adair Sep 2026

The Cranial Nerves And Electrical Stimulation, Devin K. P. Adair

Dissertations, Theses, and Capstone Projects

Cranial nerves provide afferent pathways that enable bottom-up modulation of central autonomic and cognitive neural pathways. Because these pathways project to brainstem nuclei such as the nucleus tractus solitarius and engage neuromodulatory systems, including the locus coeruleus, electrical stimulation offers a mechanistically grounded approach to influencing brain function. This thesis tested whether active transcutaneous auricular vagus nerve stimulation (taVNS) produces physiological responses indicative of parasympathetic engagement, defined as decreases in heart rate, increases in heart rate variability, and decreases in respiration relative to a dose-matched earlobe control condition. Using cardiac and respiratory measures as physiological markers, taVNS at the tragus …

Patterns Of Autonomous And Conditional Neural Specification For The Brain And Ventral Nerve Cord In Annelida, Nicole B. Webster, Johnny A. Davila-Sandoval, Allan M. Carrillo-Baltodano, Skyler Duda, B. Duygu Özpolat, Neva P. Meyer Sep 2026

Patterns Of Autonomous And Conditional Neural Specification For The Brain And Ventral Nerve Cord In Annelida, Nicole B. Webster, Johnny A. Davila-Sandoval, Allan M. Carrillo-Baltodano, Skyler Duda, B. Duygu Özpolat, Neva P. Meyer

Biology

Evolution of central nervous systems is a long-debated topic. Similar mechanisms of conditional neural specification linked to dorsal-ventral (D–V) axis formation have been used to support homology across several taxa. We tested for autonomous versus conditional neural specification in two distantly related annelids, Capitella teleta and Platynereis dumerilii, using blastomere isolations and ablations. Our results demonstrate autonomous specification of anterior neural tissue in isolated first-quartet (1q) micromeres for both annelids. In both annelids, partial larvae derived from isolation of the somatoblast, micromere 2d, also resulted in the formation of trunk neural tissue (ventral nerve cord or VNC), suggesting that this …

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 Aug 2026

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 …

Phenology Of Ground-Dwelling Beetle Assemblages (Coleoptera: Carabidae, Staphylinidae) From Three Fir Stands Of Southern Québec (Canada), With Comparison Among Selected Species Between 1985 And 2006-2010, Claire Levesque, Gilles-Yvon Levesque

The Great Lakes Entomologist

A total of 5,303 adult epigaeic beetles (Coleoptera) were collected using pitfall traps across three balsam fir (Abies balsamea (Linnaeus) Miller) stands in southern Québec (Canada). Sampling occurred during May–September 1985 in sites representing three distinct understory vegetation types. Three dominant families (Carabidae, Leiodidae and Staphylinidae) together represented at least 93% of catches at each site. Staphylinidae were less abundant than Carabidae at two sites, whereas Carabidae and Staphylinidae were collected in similar numbers at a third stand. Associated with increased abundance and heterogeneity of the understory vegetation, we observed 1) the decrease of specialist forest carabids, often active …

Paper Wasp Species Polistes Fuscatus (Hymenoptera: Vespidae) Tracks Urban Lead (Pb) Levels More Than Polistes Dominula, Lindsey R. Kemmerling, Anna L. Lovat, Allison A. Hanka, Emilie C. Snell-Rood

The Great Lakes Entomologist

Lead (Pb) is a persistent, toxic pollutant with widespread but inequitably distributed impacts, especially for humans in urban areas. The impacts of lead pollution on other organisms is largely unknown, even as they commonly experience exposure to lead alongside humans. We tested hypotheses regarding the lead concentrations of paper wasps across a gradient of pollution relative to soil and human lead levels, and correlations with wasp body condition. We collected two species of paper wasp across an urban gradient of lead pollution: Polistes fuscatus (Fabricius) (Hymenoptera: Vespidae), native to our study location, and Polistes dominula (Christ), nonnative to our study …

Long-Term Monitoring And Response Of Papaipema Sciata Bird (Lepidoptera: Noctuidae) To Prescribed Fire In Michigan (Usa), Gregory J. Norwood, Logan M. Rowe, Brett A. Degregorio, David L. Cuthrell, Aaron D. Meredith, Steven M. Gray

The Great Lakes Entomologist

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 Aug 2026

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 Aug 2026

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 …

Distribution And Status Of Silphium Herb Gall Wasps (Cynipoidea: Aulacideini: Antistrophus) And Their Associated Endophytic Communities In Wisconsin, Richard A. Henderson, Louis F. Nastasi, Jay Watson, Scott Sauer

The Great Lakes Entomologist

At least six described species of the herb gall wasp genus Antistrophus Walsh (Hymenoptera: Cynipoidea: Aulacideini) are dependent on the plant genus Silphium L., a plant group emblematic of now-endangered Midwestern tallgrass prairies. The distribution and conservation status of Antistrophus gall wasps is mostly a mystery, and these insects have only recently been recorded from Wisconsin. We surveyed the state for Antistrophus gall wasps on four Silphium species, whole-leaf rosinweed (S. integrifolium Michx.), compass plant (S. laciniatum L.), cup plant (S. perfoliatum L.), and prairie dock (S. terebinthinaceum Jacq.) to determine their distribution and abundance in Wisconsin.
