Plasmonic Down-Shifting Layers For Cylindrical Solar Concentrators, Kenneth Coldrick

Doctoral

The efficiency of photovoltaics (PVs) and photo-thermal (PT) systems is hindered by spectral mismatches and low thermal conductivity. A promising solution to address these issues can be the use of luminescent down-shifting (LDS) layers. This involves the incorporation of luminophores into solid or liquid layers that will act as spectral beam splitters (SBSs). In solid polymers, they form luminescent solar concentrators (LSCs), while in liquids, they act as working fluids and SBS for hybrid photovoltaic-photothermal (PVT) systems. This thesis will examine the energy conversion in both solid and liquid configurations through experimental, simulation, and economic analyses. An open-source model that …

On The Use Of Dental Microwear Texture Analysis To Determine Aetiology And Assess Wear Of Dental Tissues For Clinical Evaluation, Peter Ungar, Anderson T. Hara

Anthropology Faculty Publications and Presentations

Here, we present and synthesise some recent collaborative efforts in our laboratories to establish protocols for using dental microwear texture analysis, originally developed to reconstruct diets of fossil mammals and to aid in the clinical assessment of dental patients today. The idea is to propose a method where polyvinylsiloxane impressions, as used in many dental practices, can be combined with surface texture analysis for a rapid, non-invasive, and inexpensive approach to detect and monitor the progression of tooth wear at fine scales over short durations and help determine causal agents of dental tissue loss. We employed both in vitro experimentation …

Inactivation Of Zika Virus With Hydroxypropyl-Beta-Cyclodextrin, Cory R. Hewitt, Nicholas J. Wixon, Arthur Gallegos, You Zhou, Victor C. Huber, M. Scott. Killian

Nebraska Center for Biotechnology: Faculty and Staff Publications

Background/Objectives: Zika virus (ZIKV) infection is associated with life-threatening diseases in humans. To date, there are no available FDA-approved therapies or vaccines for the specific treatment or prevention of ZIKV infection. Variation in the ZIKV envelope protein (Env), along with its complex quaternary structure, presents challenges to synthetic approaches for developing an effective vaccine and broadly neutralizing antibodies (bnAbs). We hypothesized that beta-cyclodextrin (BCD) could be used to uniquely inactivate infectious ZIKV without disruption of Env.

Methods: ZIKV was propagated in Vero cells and admixed with BCD. The BCD-treated ZIKV was evaluated for infectivity using immunofluorescence and quantitative …

Microscopic Analysis Of Temperature Effects On Surface Colonization And Biofilm Morphology Of Salmonella Enterica, Zachariah Vice, You Zhou, Sapna Chitlapilly Dass, Rong Wang

Nebraska Center for Biotechnology: Faculty and Staff Publications

Salmonella enterica represents a diverse group of pathogens commonly associated with food contamination including red meat. Even though pre- and post-harvest cleaning and sanitization procedures are widely implemented at meat processing plants to mitigate the hazard, S. enterica cells may escape the process by colonizing, on contact, surfaces in the form of a biofilm that functions as an aggregated microbial community to facilitate mutual protection, antimicrobial resistance, proliferation and dissemination. Biofilm development is a complex process that can be affected by a variety of factors including environmental temperature. We developed methods using scanning electron microscopy and confocal microscopy with a …

Characterization Of Multispecies Microbial Communities At Beef And Pork Processing Plants And Their Impact On Pathogen Stress Tolerance, Rong Wang, Sapna Chitlapilly Dass, Vignesh Palanisamy, You Zhou, Tatum Katz, Joseph M. Bosilevac

Nebraska Center for Biotechnology: Faculty and Staff Publications

Escherichia coli O157:H7 and Salmonella enterica are major foodborne pathogens. Biofilm formation may potentially contribute to product contamination by these pathogens at meat processing facilities. Further, pathogen stress tolerance may vary significantly due to the interactions with the multispecies microbial community at meat plants, which may be affected by processing activity, animal species, and the local selective pressure caused by sanitization practices.

We characterized natural microorganisms collected from floor drains at various areas at three beef plants and two pork plants and analyzed their impact on pathogen sanitizer tolerance.

The pathogen strains were able to integrate efficiently into the multispecies …

Semaglutide And The Evolving Landscape Of Metabolic Dysfunction–Associated Steatotic Liver Disease, Rohan Karkra

Digital Journal of Clinical Medicine

The FDA approved Semaglutide (Wegovy™) on August 15, 2025, for adults with MASLD and moderate to advanced fibrosis (F2–F3), making it the second approved therapy after Resmetirom. MASLD affects up to 38% of adults and is now the leading cause of liver disease. In the phase 3 ESSENCE trial, Semaglutide achieved resolution of steatohepatitis without worsening fibrosis in 62.9% versus 34.3% with placebo, with additional benefits in weight loss and glycemic control. While long-term data remain pending and access barriers exist, this approval marks a significant advance in MASLD therapy with meaningful histologic and metabolic improvements.

Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho

Karl Reinhard Publications

Archaeoparasitology has been conducted in the Southwest for 57 years. In the first decade of the period, two pictures of parasitism emerged. Analysis of compressed organic sediments from a latrine at Elden Pueblo presented a spectrum of geohelminths not different from medieval Europe. These findings contrast pronouncedly with an analysis of coprolites from all other studies that show consistent pinworm parasitism at other sites in the Southwest. We summarize the paleoepidemiological bases for these contrasting phenomena.

Molluscum Dermatitis In A Pediatric Patient, Garrett Furth, Olivia Mayer, Marshall Hall, Henry Lim, Christian Scheufele, Michael Carletti, Stephen Weis

North Texas Research Forum 2025

Atopic dermatitis (AD) is a chronic relapsing condition characterized by irritation, redness, inflammation, and itching of the skin. The cause of AD is theorized to be multifactorial, including genetic components, such as mutations in filaggrin, environmental exposures, and immune predisposition. AD often presents in childhood and adolescence, but can appear at any age. AD eruptions arise through various triggers, which commonly include soaps, detergents, fabrics, and cold or hot weather. Importantly, viral infections can also serve as a trigger, causing systemic inflammation via host defense mechanisms. Molluscum contagiosum (MC) is a double-stranded DNA virus that classically manifests as small, dome-shaped, …

Clinical Evaluation And Management Of Terra Firma-Forme Dermatosis: Insights From Two Diverse Cases, Henry Lim, Rafael Do Valle, Reem Ayoub, Marshall Hall, Michael Carletti, Stephen Weis

North Texas Research Forum 2025

Terra Firma-Forme Dermatosis (TFFD), also known as Duncan’s dirty dermatosis is a benign, asymptomatic dermatologic condition characterized by well-demarcated brown patches to hyperkeratotic papules or plaques. It most commonly affects the neck, trunk, and face but can appear on other body regions. A key diagnostic feature is that these lesions persist despite routine washing with soap and water but can be removed by forcibly wiping the affected area with 70% isopropyl alcohol, revealing normal underlying skin.
