The Implications Of Ferroptosis In Antibiotic Resistance, Marysol Hohl

Senior Honors Theses

Bacterial infections in the United States are becoming increasingly resistant to existing antibiotic treatments. Due to projected increases in resistance and the recent decrease in novel antibacterials, experts have determined that the United States is in the “post-antibiotic era.” The scientific community has failed to resolve resistance despite the continual discovery of new antibiotic compounds. In the past decade, a novel form of cell death called ferroptosis has been implicated in antibiotic treatment by employing the use of nanotechnology. This literature review will describe the problem of bacterial resistance and demonstrate how current research is pioneering a new age of …

Genome-Wide Identification Of Qtls Associated With Iron Deficiency Tolerance In Soybean Reveals Gata12 As The Integrator Of Iron Signaling In Roots, Amir Maqbool, Ahmet Şahi̇n, Allah Bakhsh, Emre Aksoy

Turkish Journal of Botany

Iron (Fe) is an essential micronutrient required for plant growth and development. However, its deficiency causes substantial yield losses, particularly in alkaline soils. Soybean (Glycine max) serves as an ideal model to study Fe deficiency chlorosis (IDC) due to its inefficient Fe uptake from the soil. Although the quantitative trait loci (QTL) associated with IDC tolerance were determined in soybean, the specific genes within these QTL regions remain unidentified. In this study, it was aimed to identify and analyze the expression levels of genes present in IDC-responsive soybean QTL under Fe deficiency. Through this investigation, 6593 genes were identified within …

Beta-Carbonic Anhydrase Gene Expression Levels Change Depending On The Drought Severity In Both The Leaves And Roots Of Arabidopsis Thaliana, Sertan Çevi̇k, Oğuzhan Kurt, Ayşi̇n Güzel Değer, Ferit Kocaçinar, Rıza Bi̇nzet

Turkish Journal of Botany

In this study, it was aimed to determine the relationship between β carbonic anhydrase (βCA) gene expression levels and drought stress severity. For this purpose, the expression levels of six βCA genes in the roots and leaves of Arabidopsis thaliana were investigated under mild, moderate, and severe drought conditions. In addition, changes in the biomass, leaf water content, photosynthetic efficiency, CA enzyme activity, free proline content, and lipid peroxidation were also determined. The results showed that all of the β CA gene expression levels and CA enzyme activity increased in the leaf under mild drought conditions; however, the expression levels …

Engineering Virtuous Health Habits Using Emotion And Neurocognition: Flexibility For Lifestyle Optimization And Weight Management (Even Flow), Patrick J. Smith, Heather E. Whitson, Rhonda M. Merwin, C. Virginia O'Hayer, Timothy J. Strauman

Department of Psychiatry and Human Behavior Faculty Papers

Interventions to preserve functional independence in older adults are critically needed to optimize 'successful aging' among the large and increasing population of older adults in the United States. For most aging adults, the management of chronic diseases is the most common and impactful risk factor for loss of functional independence. Chronic disease management inherently involves the learning and adaptation of new behaviors, such as adopting or modifying physical activity habits and managing weight. Despite the importance of chronic disease management in older adults, vanishingly few individuals optimally manage their health behavior in the service of chronic disease stabilization to preserve …

Dynamics And Scaling Of Particle Streaks In High-Reynolds-Number Turbulent Boundary Layers, Tim Berk, Filippo Coletti

Mechanical and Aerospace Engineering Faculty Publications

Inertial particles in wall-bounded turbulence are known to form streaks, but experimental evidence and predictive understanding of this phenomenon is lacking, especially in regimes relevant to atmospheric flows. We carry out wind tunnel measurements to investigate this process, characterizing the transport of microscopic particles suspended in turbulent boundary layers. The friction Reynolds number Re_𝜏 = O(10⁴) allows for significant scale separation and the emergence of large-scale motions, while the range of viscous Stokes number St⁺ = 18–870 is relevant to the transport of dust and fine sand in the atmospheric surface layer. We …

Tidal Bed Stress Asymmetry And Sediment Transport In Estuaries, Austin Scott Hudson

Dissertations and Theses

Rivers and estuaries provide numerous ecological, economic, and cultural resources. The value of these resources is greatly influenced by sediment transport processes, which can be affected by human activities and climate variability. A key driver of sediment transport in tidal rivers and estuaries is tidal asymmetry of velocity and bed stress, which can manifest from both non-linear tidal interactions and linear interactions among astronomical tidal constituents.

In this study, an analytical framework is developed to examine and describe the dynamics of bed stress asymmetry in semidiurnal, diurnal, and mixed-tide estuaries (Chapter 1). While tidal velocity asymmetry has been previously analyzed, …

Glial Cell Adhesion Molecule (Glialcam) Determines Proliferative Versus Invasive Cell States In Glioblastoma, Arpan De, John M Lattier, John E Morales, Jack R Kelly, Xiaofeng Zheng, Sumod Sebastian, Jason T Huse, Frederick F Lang, Joseph H Mccarty

Faculty, Staff and Student Publications

The malignant brain cancer glioblastoma (GBM) contains groups of highly invasive cells that drive tumor progression as well as recurrence after surgery and chemotherapy. The molecular mechanisms that enable these GBM cells to exit the primary mass and disperse throughout the brain remain largely unknown. Here we report using human tumor specimens and primary spheroids from male and female patients that glial cell adhesion molecule (GlialCAM), which has normal roles in brain astrocytes and is mutated in the developmental brain disorder megalencephalic leukoencephalopathy with subcortical cysts (MLC), is differentially expressed in subpopulations of GBM cells. High levels of GlialCAM promote …

Clemency: A Tool For Extreme And Discriminatory Sentences, Benjamin N. Cardozo School Of Law

Cardozo News 2023

This article appeared in the 2023 edition of Cardozo Life magazine.

For Joaquin Winfield, April 7, 2023, will forever be a day to remember. That is when he was granted clemency by New York Gov. Kathy Hochul after serving 26 years in prison for possession of 4.6 ounces of crack. The disparity in sentences given to people from different races for similar crimes has been widely written about in recent years. Winfield was sentenced under the now-repealed Rockefeller Drug Laws of the 1970s and 1980s. He was sentenced to 37.5 years to life, one of the longest prison sentences in …

The Static And Dynamic Behavior Of Steel Storage Tanks Over Different Types Of Clay Soil, Tarek N. Salem, Ayman El-Zohairy, Ahmed M. Abdelbaset

Faculty Publications

Steel storage tanks are widely used in different fields. Most of these tanks contain hazardous materials, which may lead to disasters and environmental damage for any design errors. There are many reasons which cause the failure of these tanks such as excessive base plate settlement, shear failure of soil, liquid sloshing, and buckling of the tank shell. In this study, five models of above-ground steel storage tanks resting over different types of clay soils (medium-stiff clay, stiff clay, and very stiff clay soils) are analyzed using the finite element program ADINA under the effect of static and dynamic loading. The …

The Effects Of Engineering Summer Camps On Middle And High School Students’ Engineering Interest And Identity Formation: A Multi-Methods Study, Timothy Robinson, Adam Kirn, Jenny Amos, Indira Chatterjee

Journal of Pre-College Engineering Education Research (J-PEER)

This multi-methods study explores changes in engineering interest and identity of middle and high school students (n = 79) attending introductory-level engineering summer camps at a large western land grant university. Middle school is a critical time when student interest, identity, and subsequently career choice begin to emerge and hence it is important that at this age students are given accurate information about engineering majors in college and future career opportunities in engineering. Data were collected over a period of two years in six summer camps. Three separate populations of middle and high school students participated in the summer …

Generative Video Models To Create Panning Videos Anchored On A User Image, Lenord Melvix Joseph Stephen Max

Defensive Publications Series

Creating videos with the panning effect is a cumbersome multi-step process that needs advanced video editing expertise and a deep understanding of video editing tools and source images. These are barriers to the use of panning videos in online media content. This disclosure describes the use of cloud-based video generation models to automate the creation of panning videos of user-specified duration and quality based on a user-selected anchor and satellite imagery end point. The generative model automatically identifies a panning path between the end points, identifies images along different points in the panning path, and automatically generates a panning video …

From Doubt To Degree: The Retention Of African-American Mother-Scholars, Tamala Y. Stallings

Dissertations

According to college student demographic data, the majority of undergraduate students are nontraditional. However a smaller portion of educational resources are allocated to retain nontraditional college students in comparison to traditional college students. An even smaller portion of resources are allocated for the retention of sub- populations of nontraditional college students, such as Mother-Scholars. Therefore it is imperative for postsecondary institutions to understand the needs of sub-populations like Mother-Scholars and adequately apportion resources to increase their retention.

Upon matriculation, Mother-Scholars encounter systemic barriers within their institutions that impede their college persistence. Furthermore, because of their intersectionality, Mother-Scholars have college experiences …

Materials Science and Engineering Faculty Publications and Presentations

DNA nanotechnology has now enabled the self-assembly of almost any prescribed 3-dimensional nanoscale structure in large numbers and with high fidelity. These structures are also amenable to site-specific modification with a variety of small molecules ranging from drugs to reporter dyes. Beyond obvious application in biotechnology, such DNA structures are being pursued as programmable nanoscale optical breadboards where multiple different/identical fluorophores can be positioned with sub-nanometer resolution in a manner designed to allow them to engage in multistep excitonic energy-transfer (ET) via Förster resonance energy transfer (FRET) or other related processes. Not only is the ability to create such complex …
