Embracing Diversity In Agricultural Economics, Timothy L. Meyer

Cornhusker Economics

To steal an overused cliché, “There’s room in the tent for everyone.” Over the 2023 academic year, I have reiterated this message to all my students, with one addition. Not only is there room for everyone, but all are invited AND welcome. Food is something we all have in common, no matter the background. I think this is why producers in the state of Nebraska feel as strongly as they do about the food they produce; it is life-giving and should be taken seriously. Nebraska Agriculture is part of what makes our state great, and that is not a secret …

The Emerging Role Of Non-Coding Rnas (Ncrnas) In Plant Growth, Development, And Stress Response Signaling, Amit Yadav, Jyotirmaya Mathan, Arvind Kumar Dubey, Anuradha Singh

Center for Plant Science Innovation: Faculty and Staff Publications

Plant species utilize a variety of regulatory mechanisms to ensure sustainable productivity. Within this intricate framework, numerous non-coding RNAs (ncRNAs) play a crucial regulatory role in plant biology, surpassing the essential functions of RNA molecules as messengers, ribosomal, and transfer RNAs. ncRNAs represent an emerging class of regulators, operating directly in the form of small interfering RNAs (siRNAs), microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs). These ncRNAs exert control at various levels, including transcription, posttranscription, translation, and epigenetic. Furthermore, they interact with each other, contributing to a variety of biological processes and mechanisms associated with stress resilience. …

Predicting Sedentarism And Its Impact On Caloric Requirements, Jacob Michels, John C. Beghin

Yeutter Institute International Trade Policy Review

A recent study conducted by PhD candidate Jacob Michels and Agricultural economist John Beghin delves into the question of whether global estimates of food insecure populations need a reevaluation of their methodology to account for increasing sedentarism. This reevaluation is prompted by the increasing prevalence of sedentary lifestyles worldwide, which calls for a redefinition of caloric thresholds indicating the onset of food insecurity. In this short article, we provide a nontechnical summary of their investigation recently published in Michels and Beghin (2024).

The Importance Of Strategic Planning For Farmers And Ranchers, Larry Van Tassell

Center for Agricultural Profitability

Planning, or more specifically, strategic planning, is a process of defining long-term goals and objectives of an organization and determining the best course of action to achieve them. It involves such steps as defining the current situation, identifying strengths, weaknesses, opportunities, and threats, and developing a plan of action to take advantage of opportunities and overcome challenges. Parsons (2018) outlined six key components of a business plan and why a farm or ranch should make the effort to develop a business plan.

High-Fat Diet Feeding Exacerbates Hiv-1 Rectal Transmission, Saroj Chandra Lohani, Amanda E. Ramer-Tait, Qingsheng Li

Department of Food Science and Technology: Faculty Publications

High-fat diet (HFD) is well known to impact various aspects of gut health and has been associated with many diseases and inflammation. However, the impact of HFD feeding on HIV-1 rectal transmission has not yet been well addressed. With an increasing threat of HIV-1 infection in men who have sex with men (MSM), where the rectal route is the primary mode of infection, it is imperative to understand the impact of HFD on gut microbiota and inflammation and consequently, its effect on HIV-1 rectal transmission. Here, we utilized our double humanized bone marrow, liver, thymus (dHu-BLT) mouse model to assess …

Taxonomic Advances Driven By The Genomic Analysis Of Butterflies, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

This study presents new findings based on a large-scale analysis of butterfly genomic sequences. Focusing on species identification through comparative genomics, we define subspecies as populations differentiated to a lesser extent than distinct species ("species in the making"). Additionally, we propose further adjustments to the current butterfly classification. As a result, 3 subgenera, 12 species, and 4 subspecies are described as new. New subgenera are (type species in parenthesis): Hyalaus Grishin, subgen. n. (Papilio epidaus E. Doubleday, 1846) of Eurytides Hübner, [1821] (Papilionidae Latreille, [1802]) and Astria Grishin, subgen. n. (Lycaena astraea Freyer, 1851) of Glaucopsyche Scudder, 1872 …

A "Quic" Way To Quality Improvment, Rosalie Mince, Michelle Kloss

Instructional Leadership Abstracts

QUICs (Quality Improvement Cycles) serve as concise and valuable summaries of important work being done at Carroll Community College (located in central Maryland, United States).

The steps in the Reflective Improvement Cycle are: Define/Redefine; Design; Implement; Analyze; Modify/Maintain

Reflections from one QUIC often lead to follow-up inquiries the next year, and often, innovative ideas from one area are replicated and customized for other areas. The QUIC process would be easily replicable by instructional administrators at other institutions of higher education, requiring minimal resources beyond the time of a champion at the institution to launch the effort and catalog completed reports.

Slight Cost Of Production Changes Noted In The 2024 Nebraska Crop Enterprise Budgets, Glennis Mcmclure

Cornhusker Economics

The Nebraska crop budgets are available for the 2024 production season. The 84 enterprise budgets prepared in the October 2023 timeframe use input prices collected as of that time. Overall, estimates reflect slight cost of production decreases in the budgets when compared to the 2023 cost estimates. For 2024, the main drivers of cost decreases are due to decreased fuel and fertilizer costs. In some cases, pesticide costs decreased, yet for some of those products, prices increased. Seed and interest costs have increased for 2024 adding to cash expenses, while land opportunity costs and depreciation costs have continued to rise …

Metabolic Collaboration Between Cells In The Tumor Microenvironment Has A Negligible Effect On Tumor Growth, Johan Gustafsson, Fariba Roshanzamir, Anders Hagnestål, Sagar M. Patel, Oseeyi I. Daudu, Donald F. Becker, Jonathan L. Robinson, Jens Nielsen

Department of Biochemistry: Faculty Publications

The tumor microenvironment is composed of a complex mixture of different cell types interacting under conditions of nutrient deprivation, but the metabolism therein is not fully understood due to difficulties in measuring metabolic fluxes and exchange of metabolites between different cell types in vivo. Genome-scale metabolic modeling enables estimation of such exchange fluxes as well as an opportunity to gain insight into the metabolic behavior of individual cell types. Here, we estimated the availability of nutrients and oxygen within the tumor microenvironment using concentration measurements from blood together with a metabolite diffusion model. In addition, we developed an approach …

Parallels Of Quantum Superposition In Ecological Models: From Counterintuitive Patterns To Eco-Evolutionary Interpretations Of Cryptic Species, David G. Angeler, Hannah B. Fried-Petersen

School of Natural Resources: Faculty Publications

Background Superposition, i.e. the ability of a particle (electron, photon) to occur in different states or positions simultaneously, is a hallmark in the subatomic world of quantum mechanics. Although counterintuitive at first sight, the quantum world has potential to inform macro-systems of people and nature. Using time series and spatial analysis of bird, phytoplankton and benthic invertebrate communities, this paper shows that superposition can occur analogously in redundancy analysis (RDA) frequently used by ecologists.

Results We show that within individual ecosystems single species can be associated simultaneously with different orthogonal axes in RDA models, which suggests that they operate in …

The Second Digital Transformation Of Scholarly Publishing: Strategic Context And Shared Infrastructure, Tracy Bergstrom, Oya Y. Rieger, Roger C. Schonfeld

Copyright, Fair Use, Scholarly Communication, etc.

Today, the scholarly publishing sector is undergoing its second digital transformation. The first digital transformation saw a massive shift from paper to digital, but otherwise publishing retained many of the structures, workflows, incentives, and outputs that characterized the print era. A variety of shared infrastructure was developed to serve the needs of this first digital transformation. In this current second digital transformation, many of the structures, workflows, incentives, and outputs that characterized the print era are being revamped in favor of new approaches that bring tremendous opportunities, and also non-trivial risks, to scholarly communication.

Influence Of Microbes In Mediating Sorghum Resistance To Sugarcane Aphids, Edith Ikuze, Stephanie Cromwell, Paul A. Ayayee, Joe Louis

Department of Entomology: Faculty Publications

Gut microbiomes profoundly influence insect health and mediate interactions between plant hosts and their environments. Insects, including aphids, harbour diverse obligate symbionts that synthesize essential nutrients and facultative symbionts that enhance host fitness in specific ecological contexts. Sorghum (Sorghum bicolor) is a significant cereal crop cultivated worldwide that has been negatively affected by the presence of an invasive piercing-sucking insect pest, the sugarcane aphid (SCA; Melanaphis sacchari). We previously identified SC265 and SC1345 as the resistant and susceptible sorghum lines, respectively, among the founder nested association mapping (NAM) population. Here, using these resistant and susceptible lines, we …

Emerging Roles Of Cullin-Ring Ubiquitin Ligases In Cardiac Development, Josue Zambrano-Carrasco, Jianqiu Zou, Wenjuan Wang, Xinghui Sun, Jie Li, Huabo Su

Department of Biochemistry: Faculty Publications

Heart development is a spatiotemporally regulated process that extends from the embryonic phase to postnatal stages. Disruption of this highly orchestrated process can lead to congenital heart disease or predispose the heart to cardiomyopathy or heart failure. Consequently, gaining an in-depth understanding of the molecular mechanisms governing cardiac development holds considerable promise for the development of innovative therapies for various cardiac ailments. While significant progress in uncovering novel transcriptional and epigenetic regulators of heart development has been made, the exploration of post-translational mechanisms that influence this process has lagged. Culling-RING E3 ubiquitin ligases (CRLs), the largest family of ubiquitin ligases, …

In this study, we identified three novel compound classes with potent activity against Plasmodium falciparum, the most dangerous human malarial parasite. Resistance of this pathogen to known drugs is increasing, and compounds with different modes of action are urgently needed. One promising drug target is the enzyme 1-deoxy-D-xylulose-5- phosphate synthase (DXPS) of the methylerythritol 4-phosphate (MEP) pathway for which we have previously identified three active compound classes against Mycobacterium tuberculosis. The close structural similarities of the active sites of the DXPS enzymes of P. falciparum and M. tuberculosis prompted investigation of their antiparasitic action, all classes …

Characterization Of Variant Rnas Encapsidated During Bromovirus Infection By High-Throughput Sequencing, Sarah Dexheimer, Nipin Shrestha, Bandana Sharma Chapagain, Jozef J. Bujarski, Yanbin Yin

Food for Health: Publications

Previously, we described the RNA recombinants accumulating in tissues infected with the bromoviruses BMV (Brome mosaic virus) and CCMV (Cowpea chlorotic mottle virus). In this work, we characterize the recombinants encapsidated inside the purified virion particles of BMV and CCMV. By using a tool called the Viral Recombination Mapper (ViReMa) that detects recombination junctions, we analyzed a high number of high-throughput sequencing (HTS) short RNA sequence reads. Over 28% of BMV or CCMV RNA reads did not perfectly map to the viral genomes. ViReMa identified 1.40% and 1.83% of these unmapped reads as the RNA recombinants, respectively, in BMV and …

Awareness And Perception Of Ethical Issues In Libraries As Predictors Of Service Delivery By Library Personnel From Selected Polytechnics In South-West, Nigeria, Kathleen Phillips, Kathleen Chinyere Phillips

Library Philosophy and Practice (e-journal)

Abstract

Polytechnic libraries exist because they deliver services to the patrons. However, reports of previous studies, personal observations and anecdotal evidence have shown that the level of service delivery in some polytechnic libraries in Nigeria is low. Out of the several factors that could enhance the level of service delivery, compliance with ethical issues appears to be the least studied. This study therefore examined the contributions of awareness and perception of ethical issues in libraries to service delivery by library personnel in selected polytechnics in Southwest Nigeria. Descriptive survey research design of the correlational type was used and the total …

Implantation Of A Capsular Tension Ring During Cataract Surgery Attenuates Predicted Remodeling Of The Post-Surgical Lens Capsule Along The Visual Axis, Kurt A. Ameku, Caleb C. Berggren, Ryan M. Pedrigi

Department of Mechanical and Materials Engineering: Faculty Publications

Introduction: Cataract surgery permanently alters the mechanical environment of the lens capsule by placing a hole in the anterior portion and implanting an intraocular lens (IOL) that has a very different geometry from the native lens. We hypothesized that implant configuration and mechanical interactions with the post-surgical lens capsule play a key role in determining long-term fibrotic remodeling.

Methods: We developed the first finite element-growth and remodeling (FE-G&R) model of the post-surgical lens capsule to evaluate how implantation of an IOL with and without a capsular tension ring (CTR) impacted evolving lens capsule mechanics and associated fibrosis over …
