Defining Contractile And Age-Specific Remodeling In Atrial Fibrillation, Hannah Cizauskas

Dissertations

Atrial fibrillation (AFib) is the most common cardiac arrythmia worldwide and is characterized by hallmarks including electrical, fibrotic, and hemodynamic remodeling, each of which can cause or be caused by alterations in the contractile apparatus. However, there is little known about contractile remodeling in AFib. While our current understanding of AFib lacks contractile remodeling, it also largely ignores the contribution of aging-induced remodeling. Aging is the strongest risk factor for AFib development, with most patients diagnosed with AFib over the age of 70, and aging also involves the three molecular hallmarks of AFib, which could explain increased susceptibility of AFib …

Soil And Crop Productivity Under On-Farm Vermiculture-Based Farming System At Smallholder Rates In The Sub-Humid Tropics, Felix Matheri, Edward Karanja, David Bautze, Milka Kiboi

All Peer-Reviewed Publications

Introduction – Vermiculture-based manures such as vermicompost and its byproducts like vermiculture are gaining importance as viable alternative soil amendments. This is practically feasible, especially in subsistence farming, by replacing common organic and synthetic inputs that are often costly and inaccessible to farmers. However, the effectiveness of vermiculture tea as a sole amendment or in combination with other inputs has not been tested under field conditions. Moreover, its longterm impact on soil and crop productivity has not been established. Methods – We conducted an on-farm field study in farmers' fields to evaluate the effects of sole vermiculture tea (Vermi), in …

First Photographic Record Of A Pale-Colored Wild Boar (Sus Scrofa) Consistent With Leucism In The Zagros Mountains, Iraqi Kurdistan, Bahez F. Ali, Hana A. Raza, Nabaz Horeni

AUIQ Complementary Biological System

Pigmentation anomalies in wild mammals are rare and poorly documented in wild boar (Sus scrofa) populations. Leucism, characterized by partial loss of melanin while retaining normal eye pigmentation, represents one of the least frequently reported coloration anomalies in the species. During a camera-trap survey in Bamo Mountain, Zagros Mountains of Iraqi Kurdistan, an unusually pale-colored wild boar consistent with leucism was recorded. The individual exhibited cream to light-blond pelage with retained darker pigmentation on the snout and distal limbs, while the eyes remained normally pigmented. Its morphology and behavior were otherwise consistent with those of a typical wild …

Cultivating Narratives: A Critical Discourse Analysis Of Higher Education Student-Led Farms And Gardens, Maximilan Sherard, Marc T. Sager

Publications

Despite extensive research on community agriculture, little attention has been paid to student-led farms or gardens (SFGs) in higher education contexts. SFGs represent a unique site for community agriculture due to their diverse stakeholders, academic affiliations, and the institutional policies they navigate. This study examines online promotional materials from 42 SFGs located on land-grant higher education campuses across the United States. Using critical discourse analysis, we (1) map these organizations’ practices and (2) identify competing discourses about community and agriculture within their promotional narratives. We identify and explain four core practices (membership, growing, distribution, and purpose) and connect these practices …

Utilizing Diapause In A Sugarcane Borer (Lepidoptera: Crambidae) Laboratory Colony As A Cost Saving Measure, W. H. White

Midsouth Entomologist

The ability to rear insects in the laboratory broadens the scope of research opportunities available to the scientist. Our laboratory routinely rears the sugarcane borer, Diatraea saccharalis (F.), for research in host plant resistance and biological control of this important sugarcane pest. Unfortunately, insect rearing is a costly process. One option to reduce cost is to hold a founder population in diapause during times when insects are not needed. These insects can then be brought out of diapause and allowed to reconstitute the colony. A procedure was developed to put larvae of the sugarcane borer into diapuase, hold these larvae …

Rethinking Preoperative Mrsa/Mssa Screening Through Molecular Triage, Rob E. Carpenter, Greg Whitlock

Human Resource Development Faculty Publications and Presentations

Background: Preoperative screening for methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) is intended to identify patients at increased risk of surgical site infection and guide decolonization and perioperative antimicrobial prophylaxis. However, many molecular assays reduce this decision to a binary positive/ negative result, potentially obscuring clinically important distinctions in organism identity, methicillin resistance attribution, and mupirocin resistance risk. Methods: This structured narrative review organized direct perioperative evidence and indirect mechanistic, implementation, and economic evidence around one question: how MRSA/MSSA screening can move from organism detection to actionable molecular triage. Results: Useful preoperative reporting depends on assigning resistance markers …

Uti, Delirium, And Dementia: A Conceptual Bioinformatics Framework For Clinical Attribution, Rob E. Carpenter, Andrew Krouse

Human Resource Development Faculty Publications and Presentations

Urinary tract infection (UTI) is frequently invoked to explain delirium, confusion, and functional decline in persons with dementia. Yet urine positivity in this population often reflects asymptomatic bacteriuria, colonization, chronic pyuria, contamination, or sampling noise rather than clinically attributable infection. For biomedical informatics and computational diagnostics readers, this narrative review contributes an integrative conceptual bioinformatics framework for probabilistic clinical attribution of suspected UTI in dementia under uncertainty. We formalizes the attribution problem by distinguishing organism detection from a clinically plausible infection-related contribution to neurocognitive decline. The framework integrates clinical, laboratory, biological, and longitudinal data to clarify whether urinary findings are …

Exploring Immune Priming In The Species Exaiptasia Diaphana, Torrence Campos

Biology Theses

Vibrio coralliilyticus is a pathogen that infects various coral species across several reef ecosystems and causes mortality within a span of a few days. With increasing temperatures, the pathogen becomes more virulent towards coral. Probiotics such as MCH1-7 have previously been used to treat infected corals before and after exposure to V. coralliilyticus. In this study, we will be using a species of sea anemone Exaiptasia diaphana in place of coral to evaluate the effects of two V. coralliilyticus strains ATCC BAA-450 and OFT6-21. It was determined that BAA-450 was more virulent. It led to immediate stress and higher mortality. …

BACKGROUND: Pearson syndrome (PS) is a rare multisystem mitochondrial disorder characterized by single large-scale mitochondrial DNA deletions (SLSMDs). It typically presents in infancy with refractory sideroblastic anemia, exocrine pancreatic insufficiency, and failure to thrive. Due to its heterogeneous manifestations and resemblance to other hematological conditions, early diagnosis remains a clinical challenge.

CASE PRESENTATION: A south asian male infant presented with persistent pancytopenia, severe anemia unresponsive to intravenous and oral iron and multivitamin supplements, exocrine pancreatic insufficiency, failure to thrive, and metabolic acidosis. Born to consanguineous parents, the child had a significant family history of early infant deaths and hematological abnormalities. …

Nebraska And The Midwest Agtech Ecosystem: Benchmarking Innovation Investment And Translation Gaps, Ankit Chandra, Ishani Lal, Brennan Costello

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Agricultural innovation is central to the sustainable transformation of food systems, yet the capital that finances it is unevenly distributed relative to where food is produced. This paper develops a diagnostic framework for measuring this mismatch and applies it across the U.S. Midwest from 2021 to 2025, with particular emphasis on Nebraska's structural position within this landscape. Drawing on venture capital deal-flow data, 17 stakeholder interviews, and a novel strength-weakness-opportunity-gap (SWOG) ecosystem mapping methodology, we document $736 million in tracked Midwest AgTech funding across eight states (Nebraska, Iowa, Missouri, Illinois, Indiana, Kansas, North Dakota, and South Dakota). We introduce three …

Inductive thematic analysis was utilized to derive themes …

Learning About Gujarati: Cultural Identity And Family Language, Vritti Sodha

Florida Atlantic Undergraduate Research Journal

Language loss is a prevalent problem that is occurring in immigrant families in the United States. Since regional languages such as Gujarati are not used outside of households and community gatherings, it is not given much importance to learn. In order to combat this problem, community centers hold Gujarati classes for students of all ages to help preserve the language, but the lack of motivation to learn the language still remains. This is because a student needs to have a connection to the language to be motivated to learn it, which can be made through active learning. This study examines …

An In-Silico Investigation Of Induced Target Neural Activity Through Simulation-Based Inference Informed Deep Brain Stimulation, James Lee, Ty Roachford

Florida Atlantic Undergraduate Research Journal

Deep Brain Stimulation (DBS) is clinically effective for various neurological disorders, yet its underlying neuronal mechanisms remain unknown. Building on previous studies, we used an in-silico Hodgkin-Huxley biophysical model to investigate hippocampal CA1 responses to DBS. Our simulations replicate key experimental findings, confirming robust somatic depolarization at 140 Hz and a more gradual ramp at 40 Hz, alongside distinct transient and sustained voltage profiles. Both frequencies modulated firing rates, supporting the notion that DBS disrupts pathological network activity. Beyond frequency-specific effects, we employed Simulation-Based Inference (SBI) to identify the DBS features needed to suppress spiking and match a quiescent target …
