Context: Agronomic data such as applied inputs, management practices, and crop yields are needed for assessing productivity, nutrient balances, resource use efficiency, as well as other aspects of environmental and economic performance of cropping systems. In many instances, however, these data are only available at a coarse level of aggregation or simply do not exist.

Objectives: Here we developed an approach that identifies sites for agronomic data collection for a given crop and country, seeking a balance between minimizing data collection efforts and proper representation of the main crop producing areas.

Methods: The developed approach followed a …

Bullying Involvement And Depression Among Youth With Adhd: Is Positive Parenting Protective?, Jessica A. Simmons

Dissertations - ALL

Abstract Background: Youth with attention deficit / hyperactivity disorder (ADHD) are at increased independent risk for bullying involvement or depression yet the topic of bullying involvement and depression in ADHD is poorly understood and largely considered without a guiding theoretical framework. Research on the relation between ADHD and bullying is still in its early stages and less is known about the risk and protective factors that may contribute to the development or buffering of depression in these youth. Family factors such as positive parenting promote resilience in children with ADHD, help reduce the risk for youth depression and help to …

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 …

The Use Of Fecal Microbiota Transplant In Overcoming And Modulating Resistance To Anti-Pd-1 Therapy In Patients With Skin Cancer, Tahne Vongsavath, Rodd Rohmani, Kyaw Min Tun, Vignan Manne

Department of Internal Medicine Faculty Research

While immune checkpoint inhibitors have evolved into the standard of care for advanced melanoma, 40–50% of melanoma cases progress while on therapies. The relationship between bacterium and carcinogenesis is well founded, such as in H. pylori in gastric cancers, and Fusobacterium in colorectal cancers. This interplay between dysbiosis and carcinogenesis questions whether changes in the microbiome could affect treatment. Thus, FMT may find utility in modifying the efficacy of anti-PD-1. This review aims to examine the use of FMT in treatment-resistant melanoma. A literature search was performed using the keywords “fecal microbiota transplant” and “skin cancer”. Studies were reviewed for …

Determining Best Diet And Temperature Regime Of Monkeyface Pricklebacks (Cebidichthys Violaceus) For Aquaculture, Luke C. Townsend

Master's Theses

Wild freshwater eel populations are threatened due to overfishing and habitat degradation. Attempts to use aquaculture to close the eel life cycle have yet to be commercially adapted, owing largely to their complex lifecycle. Monkeyface pricklebacks (Cebidichthys violaceus) are intertidal fish that may serve as an alternative species for freshwater eels in aquaculture, as they possess several beneficial characteristics. This study aimed to optimize diet and culture temperatures to maximize monkeyface prickleback cultures by measuring growth, condition, metabolic rates, fillet composition, and critical thermal maximum (CTmax) of juvenile fish that were reared in two separate experiments: (1) on four different …

To Touch Time: U.S. Black Feminist Modernist Sculpture In The 1970s And 1980s, Sarah Louise Cowan

Art and Art History Faculty Publications

Modernist propositions long have been understood as atemporal—somehow outside of time—or insistently hailing the future. This temporal framework suppresses the contributions of those excluded from modernist canons, particularly Black women. In this article, visual and material analysis of sculptural works produced in the 1970s and 1980s by U.S. Black women artists Beverly Buchanan, Senga Nengudi, and Betye Saar reveal how Black feminists have engaged with modernist protocols in order to redress cultural erasures of Black women. These practices exemplify Black feminist modernisms, or creative practices that unsettle the racist and sexist logics of dominant cultural institutions. Each of these artists …

Nur77 Mitigates Endothelial Dysfunction Through Activation Of Both Nitric Oxide Production And Anti-Oxidant Pathways, Lin Lu, Soohwa Jang, Jiaqi Zhu, Qing Qin, Lijun Sun, Jianxin Sun

Center for Translational Medicine Faculty Papers

BACKGROUND: Nur77 belongs to the member of orphan nuclear receptor 4A family that plays critical roles in maintaining vascular homeostasis. This study aims to determine whether Nur77 plays a role in attenuating vascular dysfunction, and if so, to determine the molecular mechanisms involved.

METHODS: Both Nur77 knockout (Nur77 KO) and Nur77 endothelial specific transgenic mice (Nur77-Tg) were employed to examine the functional significance of Nur77 in vascular endothelium in vivo. Endothelium-dependent vasodilatation to acetylcholine (Ach) and reactive oxygen species (ROS) production was determined under inflammatory and high glucose conditions. Expression of genes was determined by real-time PCR and western blot …

Genetic Background Of Juniper (Juniperus Spp.) Consumption Predicted By Fecal Near-Infrared Spectroscopy In Divergently Selected Goats Raised In Harsh Rangeland Environments, Henrique A. Mulim, John W. Walker, Daniel F. Waldron, Danilo G. Quadros, Lorena F. Benfica, Felipe E. De Carvalho, Luiz F. Brito

Purdue University Libraries Open Access Publishing Fund

Background

Junipers (Juniperus spp.) are woody native, invasive plants that have caused encroachment problems in the U.S. western rangelands, decreasing forage productivity and biodiversity. A potential solution to this issue is using goats in targeted grazing programs. However, junipers, which grow in dry and harsh environmental conditions, use chemical defense mechanisms to deter herbivores. Therefore, genetically selecting goats for increased juniper consumption is of great interest for regenerative rangeland management. In this context, the primary objectives of this study were to: 1) estimate variance components and genetic parameters for predicted juniper consumption in divergently selected Angora (ANG) and composite Boer …

Microbial Contributions To Plant Function And Resistance Under A Changing Climate, Sarah Araldi-Brondolo

Dissertations - ALL

The ability of natural plant populations to respond in the face of rapid environmental change depends on the complex microbial communities with which they associate. The interactions plants have with their microbial symbionts impacts the plants growth, function, and subsequent reproduction. It is important to understand how climate change alters these interactions. First, I aimed to understand how the microbial communities among and within the roots of alpine plants changed in response to drought along an elevational gradient, providing insight into what environmental and ecological factors play a role in microbial community resistance to drought stress. Secondly, within plant populations …

Multi-Functional Phenolic Acid-Based Shape Memory Polymer Foams As Hemostatic Agents, Changling Du

Dissertations - ALL

Severe trauma causes 5 million deaths annually worldwide, 30-40% of which are due to uncontrolled bleeding. Of these, 39% of trauma wounds develop polymicrobial infections, and even if the patient can be treated in the hospital, the patient is at significant risk of contracting drug-resistant bacteria. Therefore, we developed dual incorporated phenolic acid (DPA)-based shape memory polymer (SMP) foam as a hemostatic agent. In emergencies, this DPA-based SMP foam can be injected into the deep wound to rapidly stop bleeding and disinfect the wound to prevent hemorrhage and wound infection. Additionally, when the patient is exposed in the hospital, this …

Containment: Logistics, Environmental Conflict, And The Legal Geography Of Inland Ports, Jared Charles Whear

Dissertations - ALL

In 2020, as the COVID-19 pandemic disrupted the supply chain, people worldwide received a crash course in the importance of logistics when corporations like Amazon became a lifeline for many. Before this increased public attention, however, scholars in geography had shown logistics to be a highly political yet indispensable process in the operation of global capitalism. Much of this scholarship underscores how the logistics industry frequently operates at the expense of marginalized people, workers, and the environment. In this dissertation, I expand on this work by adding a legal geography and political ecology analysis—a legal political ecology approach—to examine the …

Faculty, Staff and Student Publications

The use of cardioprotective strategies as adjuvants of cardioplegic solutions has become an ideal alternative for the improvement of post-surgery heart recovery. The choice of the optimal cardioplegia, as well as its distribution mechanism, remains controversial in the field of cardiovascular surgery. There is still a need to search for new and better cardioprotective methods during cardioplegic procedures. New techniques for the management of cardiovascular complications during cardioplegia have evolved with new alternatives and additives, and each new strategy provides a tool to neutralize the damage after ischemia/reperfusion events. Researchers and clinicians have committed themselves to studying the effect of …

Exploring Novel Frontiers: Leveraging Stat3 Signaling For Advanced Cancer Therapeutics, Taiwo Adesoye, Debasish Tripathy, Kelly K Hunt, Khandan Keyomarsi

Faculty, Staff and Student Publications

Signal Transducer and Activator of Transcription 3 (STAT3) plays a significant role in diverse physiologic processes, including cell proliferation, differentiation, angiogenesis, and survival. STAT3 activation via phosphorylation of tyrosine and serine residues is a complex and tightly regulated process initiated by upstream signaling pathways with ligand binding to receptor and non-receptor-linked kinases. Through downstream deregulation of target genes, aberrations in STAT3 activation are implicated in tumorigenesis, metastasis, and recurrence in multiple cancers. While there have been extensive efforts to develop direct and indirect STAT3 inhibitors using novel drugs as a therapeutic strategy, direct clinical application remains in evolution. In this …

Antimicrobial And Synergistic Effects Of Syzygium Cumini, Moringa Oleifera, And Tinospora Cordifolia Against Different Candida Infections, Adedayo O. Adelakun, Ayoola Awosika, Uzochukwu Adabanya, Adekunle E. Omole, Akinyode I. Olopoda, Emmanuel T. Bello

School of Medicine Faculty Publications

Introduction The burden of multiple drug resistance in human pathogens has necessitated the search for and development of antimicrobial agents with a wide range of structural classes and potentials to selectively act on the several mechanisms of actions exhibited by the pathogens. However, most synthetic antimicrobial agents have been linked with adverse side effects and high costs, furthering the need to explore more options. Syzygium cumini, Moringa oleifera, and Tinospora cordifolia are three medicinal plants used in traditional medicine systems for various infectious diseases. They contain various phytochemicals that exhibit antimicrobial activities against various bacteria, fungi, and parasites. The mechanisms …

A Survey Of Fusarium Oxysporum In Georgia Hemp Farms And Vegetable Gardens, Christopher D. Burt

Georgia Journal of Science

Recent changes in U.S. federal law have recognized the genetic and chemical differences between hemp and marijuana (Cannabis sativa L.), resulting in the legalization of hemp in the United States. The barriers to this plant’s growth in the state of Georgia are not well understood due to its prohibition for the past 80 years. Among the many possible obstacles is fungal disease. Fusarium oxysporum (Schlecht. emend. Snyder & Hansen) is a fungus that damages various crops and was previously researched as a biocontrol agent for C. sativa. Thus, this study surveyed hemp farms in Georgia to determine the prevalence …

Xun Zi On Desiring To Be Good: Desire As The Necessary Condition For The Transformation Of Nature, Angel Ting

Comparative Philosophy

There are various discussions on the role of desires in the Xun-Zi and how the transformation of nature takes place. Some scholars hold that the heart-mind can override inborn human desires, a view that is analogous to externalism; others maintain the internalism view that desires are essentially motivating in the Xun-Zi. This paper aims to resolve this seeming conflict between externalism and internalism. By introducing David B. Wong's model of being an internalist about duty and an externalist about reason, I will show that desires in the Xun-Zi are necessarily motivating because of their direction of fit, and …

A Madhyamaka Critique Of Jaegwon Kim's Supervenience Argument, Tyler J. Jungbauer

Comparative Philosophy

Jaegwon Kim’s supervenience argument objects to the possibility of emergent causation (both downward and same-level) based on both (1) the causal overdetermination of both (a) higher-level emergent events and (b) lower-level basal events, and (2) the causal closure principle of the physical domain. Kim argues that emergent causation entails epiphenomenalism. Madhyamaka Buddhist philosophy skeptically critiques the primary (ultimate) existence of causal phenomena and instead suggests that all such phenomena may only be secondarily (conventionally) existent. Mādhyamikas acknowledge that, conventionally, emergent phenomena appear to cause both basal phenomena and other emergent phenomena. However, contra Kim, Mādhyamikas doubt that causal relations ultimately …

Sustainable Futures-Integrating Indigenous Perspectives Into An Environmental Assessment Framework: An Analysis Of The Mauri Model, Anna Bettini

Journal of Environmental Sustainability

The twin concepts of sustainable development and sustainability have been key points in new policies. Nonetheless, only the Western scientific perspective is typically considered, excluding other voices and leading to a very narrow vision of “sustainability”. The following article investigates the benefits to including indigenous knowledge and principles, considering their values rather than limitations and presents two specific case studies using the Mauri Model Decision Making Framework, a tool applied for environmental assessment, seen as a more cultural-friendly sustainable approach.
