Insights Into Cerebrovascular Health: Comparative Study Of The Common Carotid And Middle Cerebral Artery, Emma Lou

2024 Fall Honors Capstone Projects - Archive

The carotid artery, responsible for blood flow to the brain, and the middle cerebral artery (MCA), which supplies the cerebrum, are both susceptible to atherosclerosis, a condition that impairs blood flow and can lead to cognitive decline and ischemic strokes. This study investigates whether blood flow and vasodilation responses in the MCA during a hypercapnic challenge are comparable to those in the common carotid artery, which supplies the entire brain. This project aims to address limitations in current assessment methods, such as transcranial and duplex Doppler ultrasonography, to ascertain whether these two arteries exhibit consistent vasodilation patterns under hypercapnic conditions. …

Analyzing Head Morphology Trends With Increasing Population Density In A Jamaican Lizard Species, Lillian Durand

2024 Fall Honors Capstone Projects - Archive

Anolis lizards are model organisms for studying natural selection and evolutionary processes. One trait that is hypothesized to be advantageous for males is head size, as larger heads lead to stronger bite forces and increased likelihood in outcompeting other males for mates. To better understand how linked head size and intraspecific competition are, the head morphology of male A. lineatopus was analyzed among Jamaican populations with varying levels of population density. Population densities were determined using standardized plot surveys and mark resight models. Head dimensions and body condition for individual lizards were measured at each site. My study found that …

Forced To Weather The Storm: Reforming The Livestock Indemnity Program To Improve Farm Animal Welfare, Cameron Krier Massey

Journal of Food Law & Policy

Each year, extreme weather events put the lives and wellbeing of millions of farm animals at risk. These events can lead to injury, suffering, acute and chronic stress, decreased productivity, and loss of life. As storms increase in frequency and intensity, efforts should be made to ensure livestock are protected. This paper proposes modifications to the Livestock Indemnity Program (LIP), a federally run disaster assistance program that compensates livestock owners and growers for animal deaths and reduced value caused by eligible conditions, including extreme weather. Surprisingly, the program does not require producers to show proof and use of a disaster …

Differential Responses Of Human Neutrophils To Legionella Species., Hannah E. Hanford

Electronic Theses and Dissertations

Legionella species are Gram-negative facultative intracellular bacterial pathogens commonly found in freshwater or soil environments where they survive and replicate within their natural protozoan hosts. Humans serve as an accidental host for Legionella species after inhalation of contaminated aerosolized water droplets or soil particles enabling the bacteria to enter the lungs, infect alveolar macrophages, and result in severe pneumonia. Evasion of degradation and proliferation within alveolar macrophages by Legionella species and manifestation of “Legionnaires’ disease” is dependent on the Dot/Icm type IV secretion system (T4SS). The T4SS apparatus is a needle-like channel for translocation of over ~350 effector proteins, depending …

Myosin Xva Isoforms Participate In The Mechanotransduction-Dependent Remodeling Of The Actin Cytoskeleton In Auditory Stereocilia, Ana I. López-Porras, Ava M. Kruse, Mark T. Mcclendon, A. Catalina Vélez-Ortega

Neurology Faculty Publications

Auditory hair cells form precise and sensitive staircase-like actin protrusions known as stereocilia. These specialized microvilli detect deflections induced by sound through the activation of mechano-electrical transduction (MET) channels located at their tips. At rest, a small MET channel current results in a constant calcium influx which regulates the morphology of the actin cytoskeleton in the shorter ‘transducing’ stereocilia. However, the molecular mechanisms involved in this novel type of activity-driven plasticity in the stereocilium cytoskeleton are currently unknown. Here, we tested the contribution of myosin XVA (MYO15A) isoforms, given their known roles in the regulation of stereocilia dimensions during hair …

A Graph Theoretical Approach To Experimental Prioritization In Genome-Scale Investigations., Stephen K Grady, Kevin A Peterson, Stephen A Murray, Erich J Baker, Michael A Langston, Elissa J Chesler

Faculty Research 2024

The goal of systems biology is to gain a network level understanding of how gene interactions influence biological states, and ultimately inform upon human disease. Given the scale and scope of systems biology studies, resource constraints often limit researchers when validating genome-wide phenomena and potentially lead to an incomplete understanding of the underlying mechanisms. Further, prioritization strategies are often biased towards known entities (e.g. previously studied genes/proteins with commercially available reagents), and other technical issues that limit experimental breadth. Here, heterogeneous biological information is modeled as an association graph to which a high-performance minimum dominating set solver is applied to …

Net Evaporation-Induced Mangrove Area Loss Across Low-Lying Caribbean Islands, Isamar M. Cortés, Jorge Lorenzo-Trueba, Andre S. Rovai, Robert R. Twilley, Mark Chopping, Temilola Fatoyinbo

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Although mangroves provide many beneficial ecosystem services, such as blue carbon storage and coastal protection, they are currently under threat due to changes in climate conditions, such as prolonged drought exposure. Under drought conditions, evaporation exceeds precipitation and high soil salinities can lead to stunted growth and die-back. To quantify this interplay, we developed a database for low-lying and uninhabited mangrove islands in the Caribbean under various evaporation and precipitation regimes. We extracted physical and biological information from each island using remote sensing techniques and coupled it with a process-based model. We used this database to develop a model that …

Wine-Rs Or Losers: Assessing Socio-Economic Impacts Of Eu Regulations On Climate-Exacerbated Plant Diseases And Pests Within Northern Italian Viticulture, Kyley N. Fishman

Undergraduate Honors Theses

As climate change furthers weather events and unprecedented hot and wet seasons, European farmers are amongst those challenged by these threats. Balancing sustainable and traditional practices while maintaining socio-economic stability can be difficult, especially under European Union (EU) agricultural regulations. A key area of concern for some agro-regulations is viticulture, or grape growing, which is amongst the most climate-sensitive agricultural sectors. These agro-regulations address multiple goals, including sustainability, exports, and cultural heritage protection. Yet, to what extent EU climate-driven agricultural regulations influence regional wine-growing operations’ socio-economics remains unclear, particularly in managing climate-aggravated pests and plant diseases. My thesis aims to …

First Breeding Confirmation For Red-Breasted Nuthatch (Sitta Canadensis) Along The Big Bend Reach Of The Platte River, Jacob C. Cooper, Cody Mcgregor, Letitia M. Reichart, Janet Steele

Nebraska Bird Review

The Red-breasted Nuthatch (Sitta canadensis) is a highly nomadic species of North American nuthatch prone to large movements across the entire continent (Ghalambor and Martin 2020). This behavior has resulted in both a lack of geographic variation across the continent and propensity to colonize isolated patches of suitable habitat (Ghalambor and Martin 2020). In the Bessey District of the Nebraska National Forest (NNF), Red-breasted Nuthatches were one of the first coniferous-forest bird species to colonize and begin breeding in the isolated planted stands of pine (Zimmer 1913, Bray 1994). Despite the increasing number of records for the species …

Fall Field Report, August–November 2024, W. Ross Silcock

Nebraska Bird Review

First off, I should reiterate that records are only mentioned in this Introduction and in the text when they add to or fine-tune data included in BONO (Birds of Nebraska – Online (outdoornebraska.gov). It was my expectation that as the number of birders and in particular those reporting to eBird continue to increase, gaps in the database will be filled and my job will become simpler. However, this expectation is yet to be realized, likely due to increasing movements and activity among birds that appears to be due to increasing severity of weather events, such as heat, cold, and drought, …
